Description

A remote-controlled electric bypass flexible cable lifting device and its working method

Technical Field

The invention belongs to the technical field of cable installation, and in particular relates to a remote-controlled electric bypass flexible cable lifting device and a working method thereof.

Background Art

The lifting and access of the bypass flexible cable is the key process of the integrated non-stop power supply operation, and it is also the most dangerous and labor-intensive step in the entire operation process. In this operation step, the lifting of the bypass cable consumes the most manpower, usually requiring at least four workers on the bucket and on the ground, and requiring a number of large and small tools, which has problems such as high labor intensity, many safety hazards, low efficiency and complicated operations. At the same time, other heavy objects or tools are often lifted during live operations, and the above problems also exist in this process.

The inventor has discovered that in the cable lifting device currently designed to assist in cable lifting work, the lifting device cannot be flexibly fixed and separated from the crossarm during operation. When not fixed to the crossarm, the stability of the entire lifting device during operation is poor and is prone to swinging and other problems. When fixed to the crossarm, the fixing structure and method are relatively cumbersome, which is not conducive to the flexible fixation and separation of the lifting device on the crossarm, affecting the lifting operation efficiency. In addition, when fixed to the crossarm, when the crossarm becomes energized due to wire damage or other reasons, leakage will affect the cable lifting device, especially the power equipment or power supply in the cable lifting device, and even cause risks such as contact. At the same time, the lifting process of the current bypass flexible cable lifting device requires staff to operate at close range, which has major disadvantages, and the stability of the lifting mechanism is poor, and the stable rise of the cable cannot be guaranteed.

Summary of the invention

In order to achieve the above-mentioned purpose, in a second aspect, the present invention also provides a working method of a remote-controlled electric bypass flexible cable lifting device, which adopts the following technical solution:

After the main line is hooked to the main line by the main line hooking mechanism and fixed to the cross arm by the cross arm connecting mechanism, the remote controller is operated to lower the bypass fixing mechanism to the bypass flexible cable by means of the lifting mechanism; the bypass flexible cable is fixed to the bypass fixing mechanism, and the remote controller is operated to lift the bypass fixing mechanism and the bypass flexible cable by means of the lifting mechanism;

When the cross-arm connecting mechanism is close to the cross-arm, the probe first contacts the cross-arm for leakage detection; if it is detected that there is no leakage in the cross-arm, then when controlled by the remote controller, the first control switch and the second control switch are both closed, and the multiple first electromagnets and the multiple second electromagnets are magnetized after being energized, and the multiple first electromagnets and the multiple second electromagnets extend outward along the through hole and are fixed on the cross-arm by magnetic force; if it is detected that there is leakage in the cross-arm, then when controlled by the remote controller, the first control switch is not closed, the second control switch is closed, the multiple second electromagnets are magnetized after being energized, and the multiple second electromagnets extend outward along the through hole and are fixed on the cross-arm by magnetic force.

Compared with the prior art, the present invention has the following beneficial effects:

1. The lifting mechanism in the present invention includes a shell, a driving source arranged on the shell, a main shaft connected to the driving source, and an insulating rope with one end wound around the main shaft, and the other end of the insulating rope is connected to the bypass fixing mechanism. Through the cooperation of the driving source, the main shaft and the insulating rope, the bypass fixing mechanism can be stably lifted, and the power source can be remotely controlled by a remote controller, which solves the problem of requiring close-range operation by the staff. At the same time, the cross-arm connecting mechanism is an electromagnetic mechanism, which can be connected and fixed with the cross-arm, ensuring stability during the lifting process, and the electromagnetic mechanism can be turned on and off and powered off by remote control of the remote controller, thereby realizing flexible fixation and separation between the cross-arm connecting mechanism and the cross-arm, ensuring work efficiency; and, when the cross-arm connecting mechanism is close to the cross-arm, the probe first contacts the cross-arm for leakage detection; if it is detected that there is no leakage in the cross-arm, when controlled by the remote controller, the first control switch and the second control switch are both closed, and the multiple first electromagnets and the multiple second electromagnets are all energized and magnetized, and the multiple first electromagnets and the multiple second electromagnets are electrically connected and magnetically connected. The two electromagnets extend outwardly along the through hole and are fixed on the cross arm by magnetic force; if leakage is detected in the cross arm, when controlled by the remote control, the first control switch is not closed, the second control switch is closed, and multiple second electromagnets are magnetized after energization. Multiple second electromagnets extend outwardly along the through hole and are fixed on the cross arm by magnetic force. At this time, the insulating pad can prevent the electricity on the cross arm from being transmitted to the cross arm connecting mechanism, thereby avoiding the problem of leakage affecting the cable lifting device when the cross arm is charged due to wire damage or other reasons, and solving the problem of leakage causing a large impact on the power equipment or power supply in the cable lifting device, as well as the risk of contact.

2. In the present invention, when the multiple first electromagnets and the multiple second electromagnets extend outward along the through hole and are fixed on the crossarm by magnetic force, the multiple first springs and the multiple second springs are stretched. When the crossarm connecting mechanism needs to be separated from the crossarm, after controlling the multiple first electromagnets and the multiple second electromagnets to be powered off, the multiple first springs and the multiple second springs can promptly pull the multiple first electromagnets and the multiple second electromagnets back into the crossarm connecting mechanism, thereby improving operational flexibility, avoiding problems such as collision between the multiple first electromagnets and the multiple second electromagnets and the crossarm or the wire outside the crossarm connecting mechanism, and avoiding the problem of the sides of the multiple first electromagnets and the multiple second electromagnets being charged after colliding with the crossarm or the wire.

3. In the present invention, when the multiple first electromagnets and the multiple second electromagnets extend outward along the through hole and are fixed on the cross arm by magnetic force, the third spring is compressed, thereby avoiding the interference of the probe with the first electromagnets and the second electromagnets, and at the same time ensuring that the probe is always in contact with the cross arm. If leakage of the cross arm is detected during the connection process, the first control switch can be promptly controlled to disconnect, and the multiple first electromagnets can be pulled back and separated from the cross arm in time by the multiple first springs, thereby further avoiding leakage of the cross arm connection mechanism.

4. In the present invention, the insulating rope adjusting member is a reciprocating motion mechanism, which can make the insulating rope evenly wound on the main shaft during the rotation of the main shaft, thereby avoiding the problem of chaotic winding of the insulating rope.

Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

Embodiment 1:

As shown in FIG1 , this embodiment provides a remote-controlled electric bypass flexible cable lifting device, comprising a main line hanging mechanism 1, a cross arm connecting mechanism 2 connected to the main line hanging mechanism 1, a lifting mechanism 3 connected to the cross arm connecting mechanism 2, a bypass fixing mechanism 4 connected to the lifting mechanism 3, and a remote controller 5;

The crossarm connecting mechanism 2 is an electromagnetic mechanism; as shown in Figure 3, the lifting mechanism 3 includes a shell 31, a driving source 36 arranged on the shell 31, a main shaft 34 connected to the driving source 36, and an insulating rope 35 with one end wound around the main shaft 34; the other end of the insulating rope 35 is connected to the bypass fixing mechanism 4; as shown in Figure 5, the electromagnetic mechanism and the driving source 36 are both wirelessly connected to the remote control 5.

In this embodiment, the cross arm connection mechanism 2 is configured as an electromagnetic mechanism, which can achieve connection and fixation with the cross arm, ensuring stability during the lifting process. If the device is not fixed to the cross arm, the entire device will have a serious shaking problem, which is not conducive to safe construction, and the electromagnetic mechanism can be turned on and off and powered off by remote control of the remote controller 5, thereby achieving flexible fixation and separation between the cross arm connection mechanism 2 and the cross arm, ensuring work efficiency. At the same time, the lifting mechanism 3 includes a housing 31, a driving source 36 arranged on the housing 31, a main shaft 34 connected to the driving source 36, and an insulating rope 35 with one end wound around the main shaft 34, and the other end of the insulating rope 35 is connected to the bypass fixing mechanism. Through the cooperation of the driving source 36, the main shaft 34 and the insulating rope 35, the bypass fixing mechanism 4 can be stably lifted, and the remote control of the power source by the remote controller 5 solves the problem of requiring close-range operation by the staff.

In some embodiments, optionally, as shown in Figure 2, the cross-arm connecting mechanism 2 includes a power supply 201, a first connecting plate 202, a first spring 203, a second connecting plate 204, a second spring 205, a first electromagnet 206, a second electromagnet 207, an insulating pad 208, an insulating plate 209, a first control switch 210, a second control switch 211 and a leakage detector 212, etc.; the leakage detector 212 is connected to a probe 2122 via a third spring 2121.

As shown in Figure 2, the power supply 201 provides electrical energy to the first electromagnet 206 and the second electromagnet 207; a first control switch 210 is provided on the wire between the power supply 201 and the first electromagnet 206, and a second control switch 211 is provided on the wire between the power supply 201 and the second electromagnet 207; the first connecting plate 202 and the second connecting plate 204 are staggered and are not located on the same plane, the first connecting plate 202 is close to the inside of the cross-arm connecting mechanism 2, and the second connecting plate 204 is close to the cross-arm outside the cross-arm connecting mechanism 2; the first connecting plate 202 is connected to multiple first electromagnets 206 through multiple first springs 203, and the second connecting plate 204 is connected to multiple second electromagnets 207 through multiple second springs 205, and the ends of the multiple second electromagnets 207 are all provided with insulating pads 208. The cross arm connection mechanism 2 is a shell as a whole, with multiple through holes on one side, and multiple first springs 203 and multiple second electromagnets 207 can move in the through holes; an insulating plate 209 is provided on the side of the cross arm connection mechanism 2 where the through holes are provided. The first control switch 210, the second control switch 211 and the leakage detector 212 are all wirelessly connected to the remote controller 5.

Specifically, when the cross-arm connecting mechanism 2 is close to the cross-arm, the probe 2122 first contacts the cross-arm to perform leakage detection; if it is detected that there is no leakage on the cross-arm, when controlled by the remote controller 5, the first control switch 210 and the second control switch 211 are both closed, and the plurality of first electromagnets 206 and the plurality of second electromagnets 207 are all energized and magnetic, and the plurality of first electromagnets 206 and the plurality of second electromagnets 207 extend outward along the through hole and are fixed on the cross-arm by magnetic force; if it is detected that there is leakage on the cross-arm, the remote controller 5 is used to control the cross-arm. During control, the first control switch 210 is not closed, the second control switch 211 is closed, and the multiple second electromagnets 207 are magnetized after being energized. The multiple second electromagnets 207 extend outward along the through holes and are fixed on the crossarm by magnetic force. At this time, the insulating pad 208 can prevent the electricity on the crossarm from being transmitted to the crossarm connecting mechanism 2, thereby avoiding the problem of leakage affecting the cable lifting device when the crossarm becomes energized due to wire damage or other reasons. This solves the problem of leakage affecting the power equipment or power supply in the cable lifting device and the risk of contact.

When the multiple first electromagnets 206 and the multiple second electromagnets 207 extend outward along the through hole and are fixed on the crossarm by magnetic force, the multiple first springs 203 and the multiple second springs 205 are stretched. When the crossarm connecting mechanism 2 needs to be separated from the crossarm, after controlling the multiple first electromagnets 206 and the multiple second electromagnets 207 to be powered off, the multiple first springs 203 and the multiple second springs 205 can promptly pull the multiple first electromagnets 206 and the multiple second electromagnets 207 back into the crossarm connecting mechanism 2, thereby improving the operational flexibility, avoiding the problems of the multiple first electromagnets 206 and the multiple second electromagnets 207 colliding with the crossarm or the wire outside the crossarm connecting mechanism 2, and avoiding the problem of the sides of the multiple first electromagnets 206 and the multiple second electromagnets 207 being charged after colliding with the crossarm or the wire.

When the plurality of first electromagnets 206 and the plurality of second electromagnets 207 extend outwardly along the through hole and are fixed on the cross arm by magnetic force, the third spring 2121 is compressed, thereby avoiding the interference of the probe 2122 with the first electromagnet 206 and the second electromagnet 207, and at the same time ensuring that the probe 2122 is always in contact with the cross arm. If leakage of the cross arm is detected during the connection process, the first control switch 210 can be promptly controlled to disconnect, and the plurality of first electromagnets 206 can be pulled back and separated from the cross arm in time by the plurality of first springs 203, thereby further avoiding leakage of the cross arm connection mechanism 2.

An insulating plate 209 is provided on the side of the cross-arm connecting mechanism 2 with a through hole, thereby preventing the cross-arm connecting mechanism 2 from being electrically connected to the cross-arm when the cross-arm connecting mechanism 2 just contacts the cross-arm and after the multiple first electromagnets 206 and the multiple second electromagnets 207 are recovered, further preventing the influence of cross-arm leakage on the cross-arm connecting mechanism 2.

In some embodiments, a hook is provided at one end of the main line attachment mechanism 1 away from the cross arm connection mechanism 2 for attachment to the main line.

In some embodiments, the main line attachment mechanism 1 and the cross arm connection mechanism 2 are detachably connected; for example, a bolt connection assembly, a plug assembly, a hook or other attachment assembly is provided between the main line attachment mechanism 1 and the cross arm connection mechanism 2, which is conducive to replacing different types of main line attachment mechanisms 1 to achieve the main line mounting requirements at different positions. Similarly, the cross arm connection mechanism 2 and the lifting mechanism 3 are arranged to be detachably connected; for example, a bolt connection assembly, a plug assembly, a hook or other attachment assembly is provided between the cross arm connection mechanism 2 and the lifting mechanism 3, and after the cross arm connection mechanism 2 is fixed to the cross arm, the lifting mechanism 3 is connected to the cross arm connection mechanism 2, which reduces the construction difficulty.

In some embodiments, the cross arm connection mechanism 2 directly uses an electromagnet, and the electromagnet's suction force is used to achieve rapid mounting on the cross arm; the electromagnet is connected to a rechargeable lithium battery through a power cord and a toggle switch, and the lithium battery can continuously power the electromagnet. After the cross arm connection mechanism 2 is placed on the lower side of the cross arm by an operator or a drone, the electromagnet is powered on by toggling the power switch to generate suction, thereby being adsorbed on the cross arm.

In some embodiments, the cross arm connection mechanism 2 directly uses an electromagnet, and the electromagnet's suction force is used to achieve rapid mounting on the cross arm; the electromagnet is connected to a rechargeable lithium battery through a power cord and a remote control switch, etc., and the lithium battery can continuously power the electromagnet, and the switch is connected to the remote control 5 through wireless communication technology. After the cross arm connection mechanism 2 is placed on the lower side of the cross arm by an operator or a drone, the remote control 5 is used to control the switch to close, so that the electromagnet is energized to generate suction, and is thus adsorbed to the cross arm; similarly, when separation is required, the remote control 5 is used to control the switch to open, so that the electromagnet is powered off and loses suction, and is separated on the cross arm.

In some embodiments, the driving source 36 is a driving motor, and the main shaft 34 is rotatably arranged on the housing 31 through bearings and other components; the output shaft of the driving source 36 is fixedly connected to the main shaft 34; when the driving source 36 rotates, the main shaft 34 is driven to rotate. The controller of the driving source 36 can be wirelessly connected to the remote control 5 through wireless connection and other technologies.

The insulating rope 35 can be set as a high-strength insulating rope such as nylon rope; one end of the insulating rope 35 is fixed to the main shaft 34 and can be wound around the main shaft 34; the other end of the insulating rope 35 is fixed to the bypass fixing mechanism 4 by crimping or bundling.

In some embodiments, the housing 31 is further provided with an insulating rope adjusting member 32, and the insulating rope adjusting member 32 is connected to the main shaft 34 via a gear set 33. The insulating rope adjusting member 32 is a reciprocating mechanism, and a through hole is provided on the reciprocating mechanism, and the insulating rope passes through the through hole; the insulating rope adjusting member 32 is configured as a reciprocating mechanism, which can make the insulating rope 35 evenly wound on the main shaft 34 during the rotation of the main shaft 34, thereby avoiding the problem of the insulating rope 35 being wound in disorder.

In some embodiments, the reciprocating motion mechanism includes a rotating shaft rotatably arranged on the shell 31, a slide groove provided on the rotating shaft, and a slider provided on the slide groove by swinging and sliding quickly; a through hole is provided on the slider, and the insulating rope passes through the through hole.

In some embodiments, the gear set 33 includes a first gear disposed on the rotating shaft by a key connection or the like, a second gear disposed on the housing 31 by rotation through a bearing or the like, and a third gear disposed on the main shaft 34 by a key connection or the like; the first gear meshes with the second gear, and the second gear meshes with the third gear; the transmission ratio can be adjusted and designed by setting the first gear, the second gear, and the third gear. The reciprocating mechanism is driven to reciprocate by the gear set 33, so that the insulating rope 35 is wound around the main shaft 34 in an orderly manner.

In some embodiments, as shown in FIG4 , the bypass fixing mechanism 4 includes a crimping block 42 connected to the insulating rope 35, and a bracket 43 connected to the crimping block 42 through a fastening nut 41. Grooves are provided on the crimping block 42 and the bracket 43; the bracket 43 is configured as an arc-shaped bracket. The fastening nut 41 is configured as an insulating nut, and the bracket 43 is a bridge-type bracket. After tightening the fastening nut 41, the crimping block 42 and the bracket 43 can be crimped. The bracket 43 is configured as a hollow structure, which reduces the overall weight and is conducive to lifting.

Specifically, after the fastening nut 41 is loosened, the crimping block 42 is opened or separated from the bracket 43, the bypass flexible cable is placed in the groove of the bracket 43, and then the crimping block 42 is closed, and the fastening nut 41 is tightened to clamp the bypass flexible cable into the bracket 43. The curvature radius of the arc of the bracket 43 is greater than the minimum bending radius of the flexible cable, which can lock the bypass flexible cable while protecting the bypass flexible cable, and avoid damage to the bypass flexible cable due to the bending radius being less than the minimum bendable radius.

A working process or principle of this embodiment is:

The operator in the bucket or the operator at ground potential mounts the entire device onto the main line and the cross arm through the main line mounting mechanism 1 and the cross arm connecting mechanism 2.

The operator remotely controls the lifting mechanism 3 through the remote controller 5 to release the insulating rope 35, so that the bypass fixing mechanism 4 falls to the ground;

The ground operator operates the bypass fixing mechanism 4 to fix the bypass flexible cable to the bypass fixing mechanism 4 .

The operator then operates the remote controller 5 to control the lifting mechanism 3 to pull up the insulating rope 35 and lift the bypass fixing mechanism 4 to the lower side of the cross arm connecting mechanism 2 .

The workers in the bucket can then hang the bypass flexible cable connector that has been lifted into place onto the main line.

After the bypass operation is completed, the operator in the bucket removes the bypass flexible cable connector from the main line.

The operator remotely controls the lifting mechanism 3 through the remote controller 5 to release the insulating rope 35 connected to the bypass fixing mechanism 4, so that the bypass fixing mechanism 4 falls to the ground under the action of gravity, and the bypass flexible cable falls to the ground along with the bypass fixing mechanism 4.

The ground operator operates the bypass fixing mechanism 4 to remove the bypass flexible cable from the bypass fixing mechanism 4 .

The operator then operates the remote controller 5 to control the lifting mechanism 3 to pull up the insulating rope 35 and lift the bypass fixing mechanism 4 to the lower side of the lifting mechanism 3 .

The operator in the bucket takes down the device as a whole and puts it in the bucket or other possible location, and the whole operation is completed. This operation process only requires two operators, one on the ground and one in the bucket or on the pole, and does not require much physical effort, which greatly improves the efficiency and safety of the operation.

Embodiment 2:

This embodiment provides a remote-controlled electric bypass flexible cable lifting device. Different from Embodiment 1, as shown in Figure 6, a control system is arranged in the lifting mechanism 3, and the control system includes a power supply module, a main control module, a push rod drive module, a limit sensor module, a motor bus communication module and an external communication module, etc. The external communication module is connected to the remote control 5.

The power module provides a stable power supply for each module in the device except the remote controller 5, and manages the low-power operation of each module. The remote controller 5 is a remote remote controller. Optionally, the power module is equipped with a filter capacitor to ensure the stability of the operation of each module. A group of high-power MOS (Metal Oxide Semiconductor) tubes are used in the circuit of the power module to realize the software control of the power on and off of a single module to achieve the function of low power consumption. Because the device may need to be mounted on the cable for more than 1 week, low power consumption requirements are required to enable the device to achieve a long working time. The specific implementation method is: after the bypass cable is mounted on the overhead wire, the system is shut down by shutting down the control circuit, and only the communication module used for wake-up is powered. The static current of this module is less than 100uA, and the power consumption is extremely low. When the device needs to work again, a remote controller is used to send a wake-up command to the communication module to wake up the device, and the system is restarted to enter the working state.

The main control module is the core of the device control part, which is used for motor control, sensor signal processing, command reception and status sending, so as to realize the operation process of lifting the flexible cable and the interaction between the staff and the device.

Optionally, the position limit detection sensor module is installed at the corresponding position, and is composed of a laser reflection sensor and related circuits, which is used to limit the insulating rope 35 and the bypass fixing mechanism 4. On the one hand, it is used to calibrate the absolute position of the insulating rope 35, and on the other hand, it prevents the insulating rope 35 from being recovered excessively and causing the bypass fixing mechanism to get stuck. The laser reflection sensor used has the characteristics of sensitive recognition and not easy to be interfered with. It is not affected by infrared and ultraviolet rays when working in the sun, so as to achieve accurate and fast recognition.

The push rod drive module includes a drive circuit and a current acquisition circuit. The drive circuit converts the PWM (Pulse Width Modulation) signal output by the main control module into a voltage through the motor drive, and the size and direction of this voltage can be freely controlled by the main control module to control the working speed and extension of the push rod. The push rod drives the lock hook in the gear set 33 to lock and unlock, so as to achieve reliable mechanical load. It can be understood that the push rod is fixed on the lifting mechanism 3. The push rod can be an electric push rod or a pneumatic push rod, etc., and a lock hook structure such as a hook or a latch is set on the push rod. When the push rod pushes the lock hook to contact one of the gears in the gear set 33, the corresponding gear is locked, and the gear set 33 is locked at this time; when the push rod pulls the lock hook to separate from the gear set 33, the gear set 33 is unlocked. The push rod current is converted into a voltage signal through a sampling resistor, and the real-time working current of the push rod is identified and calculated through the analog-to-digital conversion function of the main control module, so as to obtain the thrust of the push rod, and the precise control of the thrust of the push rod is achieved through closed-loop control.

Optionally, the external communication module includes a ZigBee protocol (ZigBee) to TTL (Transistor-Transistor Logic) module and an antenna for receiving instructions and sending device status; the external communication module is networked with a remote remote controller to achieve remote control.

Optionally, the motor bus communication module includes a CAN (Controller Area Network) transceiver module and related circuits, which are used to communicate with the motor to achieve real-time control of the motor and real-time reception of the motor status. The CAN transceiver module is not affected by high voltage and electromagnetic interference, and lightning protection devices are installed in the circuit to ensure the stability of the control signal. The CAN bus connects the motor's speed regulator module and encoder module. The motor speed regulator directly controls the forward and reverse rotation of the motor, and the encoder is used to identify the rotation of the motor so that the main control module can obtain the motor's rotation speed and calculate the motion position for intelligent control of the motor logic.

The remote controller includes buttons, a screen, and a communication module, etc. The remote controller realizes remote interaction between the user and the device. The user controls the device through buttons, and the status information of the device is displayed on the screen in real time. The remote controller and the device communicate through ZigBee networking.

Optionally, based on the control system, the operation process of the device is as follows:

S1. There is a high-strength hook at the top of the main line hanging mechanism 1 of the device. The staff first turns on the power and then hangs the device on the main line.

S2, operate the remote controller 5, send a lowering command to the device, after receiving the command, the main control module first drives the push rod to unlock the gear set 33 through the push rod driving module, the push rod drives the locking hook to release the gear lock, and the main control module determines whether the unhooking is completed by identifying the current. After the gear is unlocked, the main control module controls the motor drive spindle 34 through the motor CAN bus communication, lowers the insulating rope 35 and the bypass fixing mechanism 4, and the encoder starts to calculate the motor speed and the motor lowering distance.

S3, when the insulating rope 35 with the bypass fixing mechanism 4 is lowered to the ground, the remote controller 5 is operated to send a stop command to the device to stop lowering the insulating rope 35. At this time, the main control module calculates the lowering distance of the insulating rope 35 through the motor encoder and saves it in the internal memory for the next automatic lifting logic.

S4. The staff installs the bypass cable on the bypass fixing mechanism 4, tightens the fastening nut 41, operates the remote control 5 to send a lifting command to the device, starts lifting the insulating rope 35, and the bypass cable is lifted. The main control module calculates the movement distance in real time through the motor encoder, compares it with the previously saved lowered distance in real time, and adjusts the motor speed in real time according to the distance. The speed gradually increases at the beginning of the lifting, and slows down when approaching the top, until the motor stops at the distance and the gear set 33 is locked. The laser reflection sensor used for limiting is used as the insurance of the motor limit, and the motor will stop immediately after the sensor is triggered.

After the automatic lifting logic is completed, since the hook locks the gear set 33, the device realizes long-term unpowered mechanical mounting of the load bypass cable. At this time, the main control module controls the high-power MOS tube to disconnect the system power supply, and only retains the power supply of the external communication module, and works in a low-power sleep state. The operating current of the control system is maintained below 100uA at this time, thereby realizing long-term mounting work and the device can be awakened at any time to continue working.

After the bypass cable is installed, the staff can proceed to the next step.

S5. When the operator finishes the work, he operates the remote control 5 to send a wake-up command to the external communication module, and the device automatically starts and enters the working state. Then, a cable lowering command is sent to the device. After receiving the command, the main control module first unlocks the gear set. After the main control module recognizes that the push rod is unlocked, it controls the motor to drive the gear set 33 and the insulating rope 35 adjustment member to slowly lower the bypass cable. At the same time, the encoder calculates the distance and compares it with the previously saved distance in real time. When the distance is reached, the device lowers the bypass cable to the ground and stops automatically. After the bypass cable reaches the ground, the staff loosens the fastening nut 41 and removes the bypass cable from the bypass fixing mechanism 4.

S6, operate the remote controller 5 to send a lifting instruction to the device, and the main control module controls the motor to drive the gear set 33 and the insulating rope 35 adjusting member to automatically retract the insulating rope. This process is the same as the process of step S4.

S7. After the insulating rope is completely retracted, the operator removes the device, completing one operation process.

Through this embodiment, the operation process of remotely lifting the bypass cable is realized, the device effectively reduces the manpower in the bypass cable lifting process, and greatly improves the work efficiency. Through the low power consumption design, the device can be mounted on the wire for a long time to work, so as to realize long-term bypass operation.
