Description

Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to an anti-vibration car door lock device and an elevator. Background Technology

[0002] Existing car door lock switches typically use a combination of mechanical and electrical locks for simultaneous locking and unlocking. During normal use, the switch is engaged when the hook is closed and disengaged when the hook is lifted. Stable closure relies on the locking torque generated by the hook's own weight, or supplemented by spring compression, to ensure the overall vibration resistance of the door lock system. Whether the switch is properly engaged is crucial to the smoothness of elevator movement.

[0003] In existing car door lock integrated door knife technology, the unlocking action is driven by the door knife swing arm. The door knife is connected to the door hanging plate through the base. When there is severe car vibration, intentional violent slapping or impact on the car door by someone inside the car, or severe uneven loading of the car, during the recovery process after the door plate undergoes elastic deformation, energy is transmitted from the door plate to the door hanging plate, the door knife base, the door knife swing arm, and the car door lock. When the amplitude is large enough, the lock hook will generate an unlocking torque. Under these circumstances, during elevator operation, the car door lock switch may be momentarily disconnected for a certain period of time, the elevator safety circuit will be broken, and the elevator will stop suddenly. When the elevator opens from the closed state, the lock hook may jump. When the pin of the switch body is pulled out of the switch seat, it will interfere with the switch seat, causing the pin to require a greater opening pull force to pull out, which will damage the pin structure.

[0036] Embodiment one

[0037] As Figures 1-4As shown, an anti-vibration car door lock device of this embodiment includes a mechanical lock assembly 1, an electrical lock assembly 2, and an anti-vibration assembly 3. The mechanical lock assembly 1 includes a lock hook 11 and a lock seat 12. The lock hook 11 is rotatably mounted on the door knife base 100 to achieve locking / unlocking between the lock hook 11 and the lock seat 12. The electrical lock assembly 2 includes a switch body 21 and a switch seat 22. The switch body 21 is provided with a pin 211 for horizontal insertion with the switch seat 22 to achieve electrical conduction. The switch body 21 is mounted on the lock hook 11. The anti-vibration assembly 3 includes a guide wheel 31 and a blocking member 32. The guide wheel 31 is rotatably mounted on the lock hook 11. The blocking member 32 is a rigid structure and has a horizontal guide surface 32a. When the switch body 21 and the switch seat 22 are electrically connected, the guide wheel 31 is located at the bottom of the horizontal guide surface 32a. Figure 1 When a relative lateral movement distance L1 is generated between the guide wheel 31 and the horizontal guide surface 32a, the guide wheel 31 leaves the bottom of the horizontal guide surface 32a. The relative lateral movement distance L1 is greater than the lateral movement distance L2 from which the plug is pulled out of the switch base 22.

[0038] Among them, reference Figure 4 The door knife base 100 is mounted on the door hanging plate 200, which is connected to the car door. According to the prior art, the door knife base 100 is also provided with components such as a left door knife and a right door knife. These components can drive the lock hook 11 to rotate on the door knife base 100 to unlock it from the lock seat 12. The specific working process of how the lock hook 11 is driven to rotate is not described here.

[0039] In this embodiment, the blocking member 32 blocks the guide wheel 31 from above. When the car door is closed, if the car door is impacted by an external force or the car is severely unbalanced, the locking hook 11 will generate an unlocking torque and lift up. At this time, the guide wheel 31 and the horizontal guide surface 32a of the blocking member 32 will abut against each other, and the locking hook 11 cannot be lifted to a greater height. Within this range of motion, the pin 211 of the switch body 21 and the switch seat 22 are still in effective contact and energized, thereby effectively preventing the car door lock device from disconnecting during the normal operation of the elevator and achieving an anti-vibration effect. It also avoids interference between the pin 211 and the switch seat 22, which would require a greater door opening pull force to pull out the pin 211, thus avoiding damage to the structure of the pin 211.

[0040] When the car opens in the leveling area, the locking hook 11 moves a short distance under the limiting action of the guide wheel 31 and the blocking member 32. The pin 211 on the switch body 21 is pulled out from the switch seat 22, the guide wheel 31 is disengaged from the bottom of the horizontal guide surface 32a, and the locking hook 11 can be lifted up to unlock the locking hook 11 from the lock seat 12.

[0041] In a preferred embodiment, such as Figure 2 As shown, under normal conditions, there is a small gap between the guide wheel 31 and the horizontal guide surface 32a, so that the guide wheel 31 and the horizontal guide surface 32a do not contact each other when the door is opened and closed normally, thus avoiding friction between them and increasing the load on opening and closing the door. Under abnormal conditions, that is, when the lock hook 11 is lifted due to external force, the guide wheel 31 can rotate on the lock hook 11, and there is rolling friction between the guide wheel 31 and the horizontal guide surface 32a, thus avoiding excessive load on opening and closing the door.

[0042] Further reference Figures 1-3 The blocking member 32 further includes an inclined guide surface 32b, which is located on the side of the horizontal guide surface 32a away from the switch base 22. In this embodiment, during the closing process of the car door, if the transmission structure driving the door lock fails, or if the bearing causes uneven rotation, or if the car door is subjected to external vibration, the lock hook 11 will eventually reset slowly during the closing process. As it reaches a position close to the end of the closing process, the guide wheel 31 will abut against the inclined guide surface 32b of the blocking member 32. Under the combined action of the inclined guide surface 32b and the horizontal force of closing, the lock hook 11 will generate a larger locking torque. Thus, the anti-vibration component 3 can force the lock hook 11 to reset at a set position, preventing the pin 211 on the switch body 21 from hitting the pin, and ensuring that the electrical lock component 2 can be connected without accidents.

[0043] For details of the above plan, please refer to [reference needed]. Figure 2 and Figure 3 The blocking member 32 includes a guide plate 321, which comprises a horizontal section 3211 and an inclined section 3212. The horizontal guide surface 32a is the bottom surface of the horizontal section 3211, and the inclined guide surface 32b is the bottom surface of the inclined section 3212. To ensure that the locking hook 11 can lift after the guide wheel 31 disengages from the horizontal guide surface 32a, the angle between the inclined guide surface 32b and the horizontal plane is at least 45°.

[0044] For details of the above plan, please refer to [reference needed]. Figure 2 and Figure 3The blocking member 32 further comprises a vertical mounting plate 322, which is provided with a first strip-shaped hole 3221, the length direction of the first strip-shaped hole 3221 is arranged vertically. In this way, the installation position of the blocking member 32 in the vertical direction can be adjusted, so as to adjust the distance of the small gap between the guide wheel 31 and the horizontal guide surface 32a, and ensure that the pin 211 does not interfere with the switch base 22 after the small gap is lifted by the hook 11.

[0045] In addition, the guide wheel 31 is rotatably arranged on a connecting frame 33, the connecting frame 33 is provided with a second strip-shaped hole 331, the length direction of the second strip-shaped hole 331 is arranged horizontally, and the second strip-shaped hole 331 is fixed on the hook 11 through a bolt assembly. The second strip-shaped mounting hole can facilitate the adjustment of the installation position of the connecting frame 33 on the hook 11. In addition, the connecting frame 33 is provided with a rolling shaft 34, the guide wheel 31 is rotatably arranged on the rolling shaft 34, the rolling shaft 34 is sleeved with a shaft sleeve 35, and the guide wheel 31 is rigidly arranged, so as to ensure that the hook 11 cannot be continuously lifted regardless of the vibration external force when the guide wheel 31 and the horizontal guide surface 32a of the blocking member 32 abut each other.

[0046] As shown in Figure 4 , the position of the blocking member 32 is relatively fixed with the switch base 22. Specifically, the blocking member 32 can be directly or indirectly mounted on the sill (not shown) of the car door and the mounting bracket (not labeled in the figure) of the switch base 22. In this embodiment, the position of the blocking member 32 is fixed, and the guide wheel 31 moves with the opening and closing action of the car door.

[0047] Embodiment Two

[0048] Referring to Figure 5 and 6 , the working principle of embodiment two is basically the same as that of embodiment one, except that in embodiment two, the blocking member 32 is arranged on the other door hanging plate 200 of the door hanging plate 200 where the door blade base 100 is arranged; the blocking member 32 and the guide wheel 31 are arranged on two door hanging plates 200 respectively, and the blocking member 32 and the guide wheel 31 move towards or away from each other in two directions. Embodiment two provides more options for the installation position of the blocking member 32.

[0049] In addition, the elevator is provided with the anti-vibration car door lock device, and the stability of the elevator in the running state is improved, and the probability of accidental disconnection of the car door lock device is greatly reduced. The anti-vibration assembly ensures that the plug and the switch seat are smoothly and smoothly connected and separated, improves the working stability of the anti-vibration car door lock device, avoids damage to the plug, prolongs the service life, and reduces the maintenance frequency and cost of the elevator.

[0050] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
