Description

Smart stick equipped with cable sheath cutter and method of hot-line job using it}

The present invention relates to a smart stick and a live working method of an insulating material used in the live working method, and more particularly, to a smart stick equipped with a cable covering cutter and a live working method using the same.

Live working is a work to perform maintenance work of a high-voltage power transmission line in a state in which current is applied to the power transmission line.

In the work for maintenance of power transmission lines, special attention is required because of the danger of fatal safety accidents, because the conductors that are directly energized are often exposed, such as cutting, stripping, or installing bypass lines.

In particular, when it is necessary to remove the sheath of a cable, a considerable safety accident has occurred because a red coated glove is often worn without using proper insulating gloves.

In the case of the 2.5sq single-core wires, which are most frequently encountered by extension majors, the cable stripping is usually performed with a general subtractor and cutter. .

In order to prevent such an electric shock accident, a mechanism called an insulation stick or a smart stick is frequently used in live working. The smart stick can greatly reduce the risk of safety accidents because a tool that can be operated by the operator is attached to one end of the stick and a work tool that receives the power operated from the other end is installed so that the work can be performed with the distance between the power line and the operator as wide as possible. Can be reduced to

However, difficult tasks, such as stripping the cable, are difficult to perform by transmitting power to a remote device. Therefore, for precise coating removal work, both the ends of the smart stick and the devices installed inside have to have a fairly complicated structure, so the production cost is considerable and there is a risk of failure. There is also a risk of failure from the point of installation.

Since the live work of the power supply facility is always required to be performed as long as there is power consumption, it is possible to use it without much expense, because it is inexpensive, easy to operate, and highly reliable while preventing risks as much as possible.

Accordingly, it is urgent to develop a technology for a live cutting machine for a live wire coating machine that has an inexpensive and reliable structure for the safety of many workers who risk the day and perform maintenance of power facilities.

The specific structure or functional descriptions presented in the embodiments of the present invention are exemplified for the purpose of explaining the embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention may be implemented in various forms. In addition, it should not be construed as being limited to the embodiments described herein, and should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

A smart stick equipped with a cable-clad cutting machine according to the present invention includes a smart stick 20, a driving module 30 installed at a user side end of both ends of the smart stick 20, and a power transmission line, as shown in FIG. It is composed of a head module 10 installed on the side.

The smart stick 20 is an insulated bar that separates the distance between the work tool and the worker to prevent electric shock of the worker in the live wire work, and a mechanism is built in the smart stick 20 to allow the worker to stop at one end of the smart stick 20. In the case of manual operation, the mechanism installed at the other end of the smart stick 20 is manufactured to operate.

In FIGS. 1 to 4, the smart stick 20 may be seen to be thick and short since both ends can be observed with one eye, but in practice, it is manufactured to be long to secure a gap between the operator and the power transmission line.

The driving module 30 is installed on one end of the smart stick 20, as shown in Figure 2, the rotation drive unit for manually generating a rotational movement, and is installed inside the smart stick 20 of the rotation drive unit It consists of a reciprocating motion unit that receives the rotational motion and converts it into a pendulum motion, and a drive case (36). The more detailed structure will be described later.

The head module 10 includes a head case 17 installed at the other end of the smart stick 20, a gear unit built in the head case 17, and receiving pendulum motion from the reciprocating unit to convert it into rotational motion, The blade 152 is formed on the inside, and is composed of a cutting gear 15 that cuts the sheath of the power transmission cable by rubbing the blade 152 in the circumferential direction of the power transmission cable while receiving the rotational motion of the gear unit and performing circular motion.

That is, the covering cutting of the transmission line is made of a cutting gear 15, and the driving module 30 is responsible for driving the cutting gear 15.

More specifically, the rotary drive unit penetrates the drive case 36 and protrudes out of the drive case 36 as shown in FIG. 2, and is manually drilled into the drive handle 34 and the drive case 36. Consists of a cam 33 installed at the end of the drive handle 34, the reciprocating unit is formed elongated, the vibration rod 21 embedded in the smart stick 20, and the upper portion of the vibration rod 21 It is installed at the lower part and is made of a spring that keeps the pendulum motion of the vibrating rod 21 with elastic force.

Therefore, as the cam 33 rotates, the lower portion of the vibrating rod 21 is hit, so that the intermittent rotational movement of the cam 33 is converted into a continuous pendulum movement of the vibrating rod 21.

In particular, the springs installed on the upper and lower portions of the vibrating rod 21 are installed with the same spring, and the vibrations of the upper and lower portions of the vibrating rod 21 are formed after a certain period of time, so that the duration of the pendulum movement increases As a result, a constant cycle may be formed.

Specifically, as shown in FIGS. 2 and 4, the vibrating rod 21 is fixedly coupled to the upper portion of the vibrating rod 21 by an upper variable plate 311 that is raised and lowered using the inner surface of the head case 17 as a guide. In the lower part, an upper variable plate 311 that is elevated using the inner surface of the lower case as a guide is fixedly coupled to the upper part of the vibration rod 21. In this case, in FIGS. 2 and 4, the upper spring 312 and the lower spring 322 are respectively shown to be installed on the upper surfaces of the upper variable plate 311 and the lower variable plate 321, and the upper end of the upper spring 312. Is coupled to the bottom surface of the upper fixing plate installed inside the head case 17, and the upper end of the lower spring 322 is coupled to the bottom surface of the lower fixing plate corresponding to the upper plate of the driving case 36.

However, in this case, when the specifications of the upper spring 312 and the lower spring 322 are different from each other, when the vibration rods 21 are moved up and down due to the shock transmitted from the cam 33, it takes time to reach resonance with each other, and rather, Since the elastic period is different, vibration may be attenuated, resulting in the vibration rod 21 not being variable.

Accordingly, in the example of FIGS. 2 and 4, when the upper spring 312 and the lower spring 322 are unified as having the same specifications, the resonance frequency can be directly reached with the raising and lowering of the vibrating rod 21, and thus the driving handle By rotating the 34 several times, resonance can be continued for a certain period of time, so that the variable of the vibration rod 21 can be maintained, and thus the operation can be drastically facilitated.

That is, if the operator rotates the drive handle 34 several times, the up and down vibration of the vibrating rod 21 can be continued several times to tens of times more, and thus, the operator simply rotates the drive handle 34 intermittently. The vibration of (21) can be maintained continuously.

Next, the path through which the upper and lower vibrations of the vibrating rod 21 are transmitted to the head module 10 installed in the upper portions of FIGS. 2 and 4 consists of racks and pinion gears 11 and 12 installed on the top of the vibration rods 21. .

As shown in FIG. 4, the rack rod 11 may be attached to the upper end of the vibrating rod 21, or the upper end of the vibrating rod itself may be configured as a rack gear 11.

And, as shown in Figure 4, the gear unit is connected to the pinion gear 12 and coaxially rotates with the pinion gear 12 to transmit the rotational motion to the cutting gear 15, the pinion gear diameter 12 ) Is formed larger than the linear speed of the pinion gear 12 to amplify the rotational movement at a linear speed greater than the linear speed, the fine variable of the vibration rod 21 is expanded to cut gear 15 ).

The higher the amplitude of the pendulum motion of the vibrating rod 21, the faster the kinetic energy is attenuated due to the potential energy of the vibrating rod 21. Therefore, the up and down amplitude of the vibrating rod 21 is made to be less than a certain length.

However, in order for the cutting gear 15, which will be described later, to cut the cable sheath in 360 degrees, the cutting gear 15 must be changed to a certain angle or more. Therefore, the amplifying gear 14 has an effect of further amplifying the linear speed of the pinion gear 12 so that the maximum vibration range of the cutting gear 15 can be closer to 180 degrees even if the amplitude of the vibration rod 21 is small. do.

The rotational motion of the amplifying gear 14 is transmitted to the cutting gear 15.

The cutting gear 15 is a shape that is cut out and removed by a certain angle from the circle as shown in FIG. 6. The shape is cut out by an angle of about 180 degrees. However, an embodiment in which an incision is less than 180 degrees or an incision of 180 degrees or more is possible.

The cutting gear 15 is thus formed in a circular arc shape, a gear unevenness 151 that can be engaged with the amplifying gear 14 is formed on the outer circumferential surface, and a blade 152 capable of cutting the sheath of the transmission cable on the inner circumferential surface. ) Is formed.

However, the cutting gear 15 is only engaged with the amplifying gear 14 in the gear unevenness 151 on the outer circumferential surface, and can be displaced without additional support means.

At this time, if a technique for supporting a general circular motion member is applied, it is inevitable to rotate. However, since the power transmission cable must be coupled to the center of rotation, the cutting gear 15 cannot be supported by a conventional rotation axis.

In order to solve this problem, in the present invention, as shown in FIG. 6, guide grooves 153 are formed on both sides of the cutting gear 15 in the same semicircular shape as the cutting gear 15, and the rolling bearing 16 is provided. It is installed on the inner wall of the head case 17 so that the guide groove 153 must be installed to pass through the rolling bearing 16 position, so that the cutting gear follows the same circular trajectory as if the rotating shaft was installed at the center of the cutting gear 15. 15 is configured to be variable.

That is, the rolling bearing 16 is fixed to the position itself so as not to deviate from the installation position, but can be rolled while rotating freely in place, so the rolling bearing 16 minimizes friction with the cutting gear 15 and at the same time cutting gear 15 ) Can support the rotational motion of the cutting gear 15 with the same effect as being rotated with a rotating shaft.

Due to the above-described configuration, when the transmission cable is enclosed inside the cutting gear 15 through the incision of the cutting gear 15, the pendulum motion of the vibrating rod 21 through the cam 33 in the drive handle 34 is The pendulum motion is generated and transmitted to the cutting gear 15 through the rack and pinion gear 12 and the amplifying gear 14, so that the cutting gear 15 performs a rotational motion in which the rotational direction is switched at regular cycles, thereby cutting The blade 152 formed inside the gear 15 may cut the sheath of the transmission cable.

At this time, the rotation range of the cutting gear 15 may be rotated so as to cover and cut most of the circumferential outer circumferential surface of the power transmission cable while having an incision where the power transmission cable can be nested as shown in FIG. 7.

In addition, as can be seen from the above-described configuration, since the cutting operation is performed for a predetermined time with a minimum operation through simple configurations without any power supply, the safety of the worker is promoted, especially in a live-line operation, which is often performed at high altitude. Even the convenience of work can be considered together, and it can be purchased and used at a low cost, so that safety work can be widely used.

On the other hand, referring to Figure 8, the cable-clad cutting machine according to the present invention may be configured to operate completely fully without a handle and a battery and a motor are applied instead of a manually operated drive handle.

On the other hand, the live working method using a smart stick according to the present invention, by approaching the cutting gear 15 to the power transmission cable, the step of mounting the cutting gear 15 on the power transmission cable so that the power transmission cable contacts the blade 152 , After operating the drive module 30, the rotation of the cam 33 is sequentially transmitted to the vibration rod 21 and the amplifying gear 14, and then operating the cutting gear 15 to operate, and the cutting gear 15 And repeating the operation of tilting the smart stick 20 by 5 to 20 degrees and returning the original position so that the contact range between the transmission cable and the outer circumferential surface of the transmission cable is 360 degrees, and the sheath of the transmission cable is cut off. And then recovering the cable-clad cutter.

At this time, it should be noted that the smart stick is repeatedly inclined a little to make the contact range between the cutting gear 15 and the power transmission cable 360 degrees over the entire circumferential direction of the power transmission cable, and then the re-establishment motion is repeated 2 or 3 times. Will do.

In addition, the details of the live working method will be omitted, since most of the description of the cladding cutter is redundant.

The present invention described above is not limited by the above-described embodiments and accompanying drawings, and various substitutions, modifications, and changes are possible within the scope of the present invention without departing from the technical spirit of the present invention. It will be obvious to those who have the knowledge of.
