Description

Asynchronous door knife assembly of elevator car door lock

Technical Field

The invention relates to an asynchronous door knife assembly of an elevator car door lock.

Background

As an important component of the elevator door machine device, there are two types, namely an asynchronous door knife and a synchronous door knife. In the new revised national standard, there is a definite regulation on the opening of the car door, 1, if the elevator is stopped in the unlocking area for any reason, the car can be manually opened with a force of not more than 300N in the landing and the car where the car is located; 2. to limit the opening of the doors by personnel in the car, the elevator is stopped in the non-unlocking zone, a force of 1000N is applied at the door opening limiting device, and the opening of the doors cannot exceed 50mm. Therefore, the elevator door should have an anti-theft function, and when the elevator car is in a non-unlocking area, people in the elevator car cannot take off the elevator car door, and the elevator door cannot be opened under the condition that the elevator door motor accidentally acts, so that passengers are prevented from being accidentally injured due to the opening of the elevator during non-landing.

The technical proposal of the asynchronous door knife is to add an anti-theft lock hook based on the original structure of the asynchronous door knife. The left cutter arm and the right cutter arm of the door cutter are mutually independent and are connected with the anti-theft lock hook through a specific mechanical structure; the horizontal movement of the left cutter arm or the right cutter arm can drive the anti-theft lock hook to tilt upwards so as to achieve the aim of unlocking the car door lock, thereby meeting the national standard anti-theft requirement of the car door.

In order to ensure the safety of normal up-down operation of the elevator, the distance between the door knife arm and the landing door ball is generally set to be 8-10 mm, the distance between two landing door balls arranged on each landing door lock in the horizontal direction is 7mm, the landing door lock rotates around an O point by 7mm, namely the landing door lock rotates from a horizontal locking state to an upturned unlocking state, and the landing door can be opened at the moment. The left cutter arm or the right cutter arm of the asynchronous door cutter moves horizontally for a certain distance, which is generally not less than 3mm, and then the lift gate is unlocked by driving the upwarp of the anti-theft lock hook through a specific mechanical structure.

The action process of the asynchronous door knife in the door opening process of the door machine is as follows: the car moves to an unlocking area, namely a leveling area, after the car door drives the asynchronous door knife to horizontally move by 8-10 mm under the drive of a motor, the right knife arm starts to touch a landing door lock moving ball, the car door continues to be opened, the car door is horizontally moved by 10mm again (namely, landing door lock unlocking swing 7mm and right knife arm unlocking floating 3 mm) to complete landing door lock unlocking, meanwhile, the car door lock unlocking is completed through the floating of the right knife arm, and the car door drives the landing door to be opened together after unlocking, and the car door is opened 18-20 mm more than the landing door. The left cutter arm falls down to lean against the layer gate ball under the action of gravity in the moving process of the gate knife.

The action process of the asynchronous door knife in the door closing process of the door machine is completely opposite to the door opening process.

Elevators are used as traffic devices for transporting passengers and operate in building shafts for a long time, with elevator doors being the only passage for passengers to enter and exit the car. In general, the elevator has a very severe running environment, dust, solid foreign matters and the like are often deposited in a sill groove serving as a guiding function, and the running resistance of a landing door is often increased by the foreign matters such as dust and the like, so that the landing door cannot be closed in place, and the car door is closed in place. The reason that the landing door cannot be closed in place is also artificial blocking, such as a key, a thin object and the like, which are blocked at the landing door.

When the elevator door is closed in place and the landing door cannot be closed in place, the elevator system can reopen the elevator door because the safety loop of the landing door lock is not connected; in the process of opening the car door, the car door lock hook is blocked by a fixed lock seat fixed on the door machine, and the car door can not be opened in an unlocking area, so that a person closing accident occurs. The reason why the car door lock hook is locked by the fixed lock hook is as follows: the national standard requires that in order to limit the opening of the car door by personnel in the car, 1000N force is applied to the door opening limiting device, and the opening of the car door cannot exceed 50mm, so that under the limit condition, when the car door is closed in place, the distance between the car door lock hook and the fixed lock hook is not more than 25mm; when the landing door is not closed in place, the moving distance of the asynchronous door knife for unlocking the landing door and the car door is at least: 16-20 mm+7mm+3mm= (26-30 mm). Therefore, the distance value is larger than the distance between the car door lock hook and the fixed lock hook, so that the car door lock hook and the landing door lock hook cannot be forced to tilt, and unlocking of the car door and the landing door cannot be achieved.

Detailed Description

The invention is described in detail below with reference to the drawings and the specific embodiments.

As a first embodiment, as shown in fig. 1 to 13, an asynchronous door vane assembly 100 for an elevator car door lock includes: the door knife comprises a door knife backboard 1, a knife arm connecting rod assembly 2, an unlocking assembly 3, a lock hook assembly 4, a car door lock assembly 5, a spring reset assembly 6, a limiting and reset assembly 7 and a manual unlocking assembly 8.

The tool arm linkage assembly 2 includes: left knife arm 21, right knife arm 25, synchronous link 22, door knife upper link 23, door knife lower link 24, right knife arm upper swing link 26 and right knife arm lower swing link 27. The synchronous connecting plate 22, the upper swing rod 26 of the right cutter arm, the right cutter arm 25 and the lower swing rod 27 of the right cutter arm are mutually hinged to form a parallelogram link mechanism. The synchronous connecting plate 22, the upper door knife connecting rod 23, the left knife arm 21 and the lower door knife connecting rod 24 are mutually hinged to form a parallelogram connecting rod mechanism. Specifically, the parallelogram link mechanism composed of the synchronous link 22, the right cutter arm 25, the right cutter arm upper swing link 26 and the right cutter arm lower swing link 27 hinged to each other acts with the movement of the synchronous link 22. The upper and lower door knife links 23 and 24 are respectively rotatably connected to the door knife backplate 1. The cutter arm connecting rod assembly 2 is hinged and fixed on the front surface of the door cutter backboard 1.

The shackle assembly 4 includes: a car door lock hook 41 and a fixed lock seat 42. The unlocking assembly 3 includes: unlocking member 32. The unlocking piece 32 is used for pushing the car door lock hook 41 to rotate so as to separate the car door lock from the fixed lock seat 42. The car door lock hook 41 is rotatably connected to the door vane backplate 1. The fixed lock holder 42 is fixed to the door machine. The car door lock hook 41 can hook the fixed lock seat 42 to perform locking. Specifically, the door lock hook 41 is tilted upward to unlock. The car door lock hook 41 is horizontally locked. The latch hook assembly 4 is disposed on the back of the knife backplate 1. The unlocking piece can directly drive the car door lock hook to move for unlocking, and can indirectly drive the car door lock hook to move for unlocking. In particular, the method comprises the steps of,

The unlocking member 32 is provided with an unlocking ball 31. The unlocking piece 32 indirectly drives the car door lock hook 41 to tilt upwards through the unlocking ball 31 for unlocking. When the unlocking ball 31 and the unlocking member 32 are taken as a whole, it can be understood that the unlocking member 32 directly drives the car door lock hook 41. Also, as an alternative embodiment, the unlocking member may be part of the right cutter arm. The unlocking component 3 is fixedly arranged on the right cutter arm 25. The unlocking piece 32 is connected to the right cutter arm 25 and is moved by the right cutter arm 25. The car door lock hook 41 is formed with an unlock arc 411. The unlocking balls 31 of the unlocking assembly 3 are in tangential contact with the unlocking arc 411 on the car door lock hook 41.

As a specific embodiment, the car door lock assembly 5 is used to control the on and off of the circuit. The car door lock assembly 5 includes: a car door lock contact plug 51 and a car door lock contact socket 52. The car door lock contact plug 51 is movable relative to the car door lock contact socket 52. The car door lock contact plug 51 is mounted to the car door lock hook 41 to move with the car door lock hook 41. When the car door lock hook 41 hooks the fixed lock seat 42, the car door lock hook 41 is horizontally locked, the car door lock contact plug 51 is inserted into the car door lock contact socket 52, and the car door lock contact plug 51 and the car door lock contact socket 52 are conducted. When the car door lock hook 41 is tilted upward to unlock the fixed lock seat 42, the car door lock contact plug 51 is disengaged from the car door lock contact socket 52, and the car door lock contact plug 51 and the car door lock contact socket 52 are disconnected.

The spring return assembly 6 includes: a return spring 61 and a spring guide lever 62. The return spring 61 applies a force that causes the synchro-link plate 22, the gate knife upper link 23, the left knife arm 21 and the gate knife lower link 24 to hinge with each other to form a parallelogram link mechanism to deform so that the left knife arm 21 and the synchro-link plate 22 come close to each other to clamp the gate ball 9 from both sides by the left knife arm 21 and the right knife arm 25. The right cutter arm 25 drives the synchronous connecting plate 22, the right cutter arm upper swing rod 26, the right cutter arm 25 and the right cutter arm lower swing rod 27 to be mutually hinged under the action of gravity to form a parallelogram linkage mechanism to deform so as to enable the synchronous connecting plate 22 and the right cutter arm 25 to be mutually close to each other and enable the left cutter arm 21 and the right cutter arm 25 to be mutually close to each other.

In the door opening process of the elevator car door, the reset spring 61 pushes the synchronous connecting plate 22, the upper door knife connecting rod 23, the left knife arm 21 and the lower door knife connecting rod 24 to be mutually hinged to form a parallelogram connecting rod mechanism to deform, and the left knife arm 21 and the right knife arm 25 clamp the door ball 9 from two sides. When the left cutter arm 21 and the right cutter arm 25 clamp the gate ball 9, the right cutter arm 25 contacts the gate ball 9 and is pushed by the gate ball 9 to drive the car door lock hook 41 to be separated from the fixed lock seat 42 through the unlocking piece 32. The spring guide lever 62 guides the return spring 61 to expand and contract. One end of the spring guide lever 62 is rotatably connected to the door knife back plate 1. The other end of the spring guide bar 62 is mounted to the left cutter arm 21. One end of the spring reset component 6 is hinged and fixed on the front surface of the door knife backboard 1, and the other end is connected with the left knife arm 21.

As a specific embodiment, when the car is stopped in the unlocking area, both the car door and landing door are locked in a state where the car door is closed in place. The door knife is fixed on a hanging plate or a door plate of the door machine, the driving force of the door machine generally directly acts on the hanging plate or the door knife, when the car door executes a door opening instruction, the door machine drives the hanging plate to drive the door knife back plate 1 to move towards the door opening direction, and because the roller guide frame 102 is fixed on the door machine, the door knife roller 213 of the left knife arm 21 rolls downwards along the roller limiting arc 1021 of the roller guide frame 102. Under the action of the elastic force of the return spring 61 of the spring return assembly 6, the cutter arm connecting rod assembly 2 rotates anticlockwise by the parallelogram connecting rod mechanism of the synchronous connecting plate 22, the upper door cutter connecting rod 23, the left cutter arm 21 and the lower door cutter connecting rod 24, and the distance between the left cutter arm 21 and the right cutter arm 25 is gradually reduced from an open state to a contracted state. The open state is a state in which the distance between the left blade arm 21 and the right blade arm 25 is large, and the contracted state is a state in which the distance between the left blade arm 21 and the right blade arm 25 is small.

During retraction of the arm linkage assembly 2, the right arm 25 is limited by the gate ball 9, and the parallelogram linkage consisting of the synchronous link 22, the right arm 25, the right arm upper swing link 26 and the right arm lower swing link 27 rotates counterclockwise, so that the right arm 25 is forced to change from the falling state to the lifting state, that is, the limit pin 251 of the right arm 25 moves from the lower arc 222-1 of 222 to the upper arc 222-2, and the above-mentioned action of the right arm 25 is called as a "floating arm". Because the unlocking component 3 is fixed on the right cutter arm 25, the unlocking ball 31 on the unlocking component 3 jacks up the unlocking arc 411 of the car door lock hook 41 along with the upward-rightward floating of the right cutter arm 25, the car door lock hook 41 rotates around the lock hook rotating shaft 44 to tilt upwards, the separation of the car door lock hook 41 and the fixed lock seat 42 is completed, and therefore, the car door is opened, and the process is called as 'right cutter arm floating unlocking'. Simultaneously, the gate ball 9 receives the extrusion of right tool arm 25, and the landing door lock takes place to rotate and opens, and this sedan-chair door and landing door unlock and open simultaneously.

The knife opening process of the gate knife is completely opposite to the knife closing process of the gate knife. Specifically, the process of opening the space between the left and right cutter arms 21 and 25 of the cutter arm link assembly 2 is a gate knife Zhang Dao, and the process of contracting the space between the left and right cutter arms 21 and 25 of the cutter arm link assembly 2 is a gate knife retracting.

As a specific embodiment, when the door machine is about to close in place, the trigger end 712 on the limiting member 71 hits the trigger ball 1011 of the trigger assembly 101, the limiting member 71 rotates after unlocking, the tool arm connecting rod assembly 2 tightens the contracted state of the door ball 9 to be unlocked, the door machine continues to close the door to drive the door back plate 1 to move towards the closing direction, the tool arm roller 213 on the left tool arm 21 rolls upwards under the limitation of the roller limiting arc 1021 of the roller guide frame 102, and accordingly the tool arm connecting rod assembly 2 is driven to rotate clockwise, and the distance between the left tool arm 21 and the right tool arm 25 gradually changes to an open state. In the process of opening the asynchronous door knife assembly 100, the right knife arm 25 is separated from the gate ball 9, the right knife arm 25 is changed from a lifting state to a falling state under the action of gravity, namely, the limiting pin 251 of the right knife arm 25 moves from the upper circular arc 222-2 of the limiting pin 222 to the lower circular arc 222-1, the unlocking ball 31 on the unlocking assembly 3 falls back leftwards and downwards along with the right knife arm 25 and is separated from the unlocking arc 411 of the car door lock hook 41, and the car door lock hook 41 rotates to a horizontal state around the locking hook rotating shaft 44, so that the locking of the car door lock hook 41 and the fixed locking seat 42 is completed; and meanwhile, the landing door lock 9 is separated from the right cutter arm 25 and also rotates to a horizontal locking state, so that the car door and the landing door are synchronously locked.

As a specific embodiment, the limiting and resetting assembly 7 includes: a stopper 71. The stopper 71 can define the position of the synchronization link 22 when the left and right cutter arms 21 and 25 clamp the gate ball 9 so that the cutter arm link assembly 2 maintains the state in which the left and right cutter arms 21 and 25 clamp the gate ball 9. The limiting and resetting assembly 7 further comprises: and a stopper post 221. The stopper post 221 is mounted to the synchronization link 22. The door knife backboard 1 is provided with a transmission avoiding hole 13 for guiding the limiting column 221 to slide. The stopper 71 is rotatably connected to the door knife back plate 1. The stopper 71 has a stopper position for preventing the stopper post 221 from moving in the transmission escape hole 13 and a release stopper position for allowing the stopper post 221 to move in the transmission escape hole 13 with respect to the door knife back plate 1.

As a specific embodiment, the elevator car door lock asynchronous vane assembly 100 further comprises: triggering the assembly 101. The trigger assembly 101 is mounted to the elevator door machine. The limiting and resetting assembly 7 further comprises: and a limit reset spring. The trigger assembly 101 contacts the stop 71 during the elevator up and down to bring the stop 71 into a contact stop position. When the door knife backboard 1 is far away from the trigger assembly 101, the limit return spring pushes the limit piece 71 to move from the release limit position to the limit position.

In the door opening process of the car door, along with the movement of the door knife back plate 1, the trigger end 712 on the limiting piece 71 is gradually separated from the trigger ball 1011 of the trigger assembly 101, the limiting piece 71 rotates under the action of the reset torsion spring, the limiting end 711 of the limiting piece 71 is clamped on the limiting post 221 on the synchronous connecting plate 22, the limiting piece 71 limits the knife arm connecting rod assembly 2 to be in a contracted state for clamping the door ball 9 through the limiting post 221, the asynchronous door knife assembly 100 is in a locking state, namely, the parallelogram mechanism formed by the knife arm connecting rod assembly 2 cannot rotate at the moment, so that the door ball 9 is always clamped by the left knife arm 21 and the right knife arm 25 in the whole door opening and closing process, and the car door lock hook 41 and the landing door lock hook are all opened all the time. The trigger ball 1011 is a roller. The limiting end 711 is a clamping groove with an arc surface.

During the closing process of the elevator car door, the trigger ball 1011 pushes the limiting piece 71 to rotate, and the limiting post 221 is separated from the clamping groove.

Specifically, the stopper 71 is substantially L-shaped. The middle part of the limiting piece 71 is hinged with the door knife backboard 1. The stop 711 and trigger 712 ends are located at opposite ends of the stop 71. The limiting post 221 is a roller.

In the blocking position, the stop post 221 abuts against the groove wall or shoulder of the catch groove of the stop 71. The abutting force is preferably self-locking, and may be a radial force, or may have a component force that drives the stopper 71 to move further toward the position of the stopper, and at least the abutting force should not push the stopper 711 out of the position of the stopper. In the closed state of the elevator door, the trigger end 712 receives a rightward pushing force to rotate to the slot wall or shoulder of the clamping slot of the limiting member 71 to separate from the limiting post 221, i.e. when the elevator door is closed, the trigger ball 1011 will separate from the trigger end 712, the pushing force should be relatively large enough to overcome the elastic force of the limiting return spring, and then in the closed state, the limiting member 71 can be pushed to rotate to a certain extent, so that the limiting member 71 is separated from the limiting position, i.e. the slot wall or shoulder of the clamping slot of the limiting member 71 separates from the limiting post 221.

Even if the landing door is blocked when the door is closed, the door knife can always push the door ball 9 to move towards the closing direction, and when the door machine is opened again, the parallelogram mechanism formed by the tool arm connecting rod assembly 2 rotates to tighten the door ball 9 so that the car door and the landing door are opened after being synchronously unlocked, and the car door cannot be opened and the accident of closing the door in an unlocking area can not occur.

As a specific embodiment, the elevator car door lock asynchronous vane assembly 100 further comprises: a tensioning knife assembly 10. The tensioning knife assembly 10 can overcome the elastic force of the return spring 61 to push the synchronous connecting plate 22, the upper door knife connecting rod 23, the left knife arm 21 and the lower door knife connecting rod 24 to be mutually hinged to form a parallelogram connecting rod mechanism to deform. The tensioning knife assembly 10 includes: roller guide 102. The roller guide frame 102 is mounted to the left cutter arm 21 and guides the movement of the cutter roller 213 to thereby move the left cutter arm 21. The roller guide frame 102 is provided with a roller limit arc 1021 guiding the movement of the door knife roller 213. Roller guide 102 is mounted to the elevator door machine. When the door vane backboard 1 moves in the direction of closing the elevator car door, the roller guide frame 102 pushes the door vane roller 213 to drive the left vane arm 21 to move upwards against the acting force of the return spring 61.

As a specific embodiment, the manual unlocking assembly 8 is used to achieve manual separation of the car door lock hook 41 and the fixed lock base 42. The manual unlocking assembly 8 includes: the pull rope 81 and the swing plate 82 are unlocked. The unlocking swing plate 82 is used for pushing the car door lock hook 41 to rotate. The unlocking swing plate 82 is rotatably connected to the door knife back plate 1. The unlocking pull rope 81 is connected to the unlocking swing plate 82. The manual unlocking component 8 is arranged on the rear side face of the door knife backboard 1, an unlocking screw is arranged at the other end of the unlocking swing plate 82 and is in contact with the car door lock hook 41, the unlocking pull rope 81 is sleeved on the unlocking screw, and the unlocking pull rope 81 on the manual unlocking component 8 is manually pulled to enable the car door lock hook 41 to swing upwards to unlock.

As a specific embodiment, for asynchronous door knives, the door knives are fixed on a hanging plate or a door plate of the door machine, and the driving force of the door machine generally directly acts on the hanging plate or the door knife backboard 1; when the car is stopped in the unlocking area, the door is pulled in the car and the door is pulled out from the hall for rescue, and the door knife is moved towards the opening direction, so that the movement process of opening the door of the car is completely equivalent. When the car stops in the non-unlocking area, the manual door-pulling or door-pulling motor in the car is started accidentally to open the door, and no interaction between the door ball 9 and the cutter arm connecting rod assembly 2 is caused, so that the cutter arm connecting rod assembly 2 always keeps a falling state due to self gravity in the retraction process, the unlocking ball 31 on the unlocking assembly 3 does not jack up the unlocking arc 411 on the car door locking hook 41 to unlock, the locking hook assembly 4 always keeps a horizontal locking state, and the car door is ensured not to be manually pulled or accidentally opened.

As a specific embodiment, the distance between the left cutter arm 21 and the right cutter arm 25 of the cutter arm link assembly 2 varies with the rotation of the parallelogram link mechanism composed of the synchronous link plate 22, the upper door blade link 23, the left cutter arm 21 and the lower door blade link 24, and the variation range is limited by the first positioning hole 11 and the second positioning hole 12 on the door blade back plate 1 through the upper limiting pin 211 and the lower limiting pin 212 on the left cutter arm 21.

The transmission avoidance hole 13 on the door knife backboard 1 is an avoidance hole of the limiting post 221, and the swing amplitude of the car door lock hook 41 from the horizontal state to the upturned unlocking state is limited by the lock hook positioning hole 43 of the lock hook assembly 4 of the positioning pin 14 on the door knife backboard 1.

The unlocking assembly 3A includes: unlocking member 32A. The unlocking piece 32A is used for pushing the car door lock hook 41A to rotate so as to disengage the car door lock from the fixed lock seat 42A. The tool arm link assembly 2A includes: left knife arm 21A, right knife arm 25A, synchronization link 22A, upper gate knife link 23A, lower gate knife link 24A, upper right knife arm swing link 26A, lower right knife arm swing link 27A, intermediate link 28, upper left knife arm swing link 29, and lower left knife arm swing link 30. The synchronous connecting plate 22A, the upper swing rod 26A of the right cutter arm, the right cutter arm 25A and the lower swing rod 27A of the right cutter arm are mutually hinged to form a parallelogram link mechanism. The synchronous connecting plate 22A, the upper door vane connecting rod 23A, the middle connecting plate 28 and the lower door vane connecting rod 24A are mutually hinged to form a parallelogram linkage mechanism. The transfer connecting plate 28, the left cutter arm upper swing rod 29, the left cutter arm 21A and the left cutter arm lower swing rod 30 are mutually hinged to form a parallelogram link mechanism. The upper and lower vane links 23A and 24A are rotatably connected to the vane back plate 1A, respectively. The unlocking member 32A is connected to the right cutter arm 25A and is moved by the right cutter arm 25A. The spring return assembly 6A includes: a return spring 61A. The return spring 61A applies a force that causes the synchronization link 22A, the gate upper link 23A, the intermediate link 28, and the gate lower link 24A to hinge with each other to form a parallelogram linkage to deform so that the synchronization link 22A and the intermediate link 28 come closer to each other to bring the left and right knife arms 21A and 25A closer to each other to clamp the gate ball 9A. The right cutter arm 25A drives the synchronous connecting plate 22A, the upper swing rod 26A of the right cutter arm, the right cutter arm 25A and the lower swing rod 27A of the right cutter arm to be hinged with each other under the action of gravity to form a parallelogram linkage mechanism to deform so as to enable the synchronous connecting plate 22A and the right cutter arm 25A to be close to each other and enable the left cutter arm 21A and the right cutter arm 25A to be close to each other. the left cutter arm 21A drives the intermediate connecting plate 28, the left cutter arm upper swing rod 29, the left cutter arm 21A and the left cutter arm lower swing rod 30 to be mutually hinged under the action of gravity to form a parallelogram linkage mechanism to deform so as to enable the intermediate connecting plate 28 and the left cutter arm 21A to be mutually close to each other and enable the left cutter arm 21A and the right cutter arm 25A to be mutually close to each other. During the door opening process of the elevator car door, the reset spring 61A pushes the synchronous connecting plate 22A, the upper door vane connecting rod 23A, the middle connecting plate 28 and the lower door vane connecting rod 24A to be mutually hinged to form a parallelogram connecting rod mechanism to deform, and the left cutter arm 21A and the right cutter arm 25A clamp the door ball 9A from two sides. When the left cutter arm 21A and the right cutter arm 25A clamp the gate ball 9A, the right cutter arm 25A contacts the gate ball 9A and is pushed by the gate ball 9A to drive the car door lock hook 41A to disengage from the fixed lock seat 42A via the unlocking piece 32A.
