Problems solved by technology

However, this trigger mechanism has disadvantages
Because the external force is affected by the speed of movement, the direction of action, etc., different factors will cause different forces acting on the lock hook, so there is uncertainty in the safety control of the lock hook

Embodiment 1

[0022] Embodiment 1: As shown in Figures 1, 2, and 5, the mechanical trigger mechanism is composed of an impact assembly 31, a brake line assembly 32, a reset assembly 33 and a bearing assembly 12. The impact assembly 31 is pressed against the bearing assembly 12 by the impact spring 16. The pull plate 3 on the top, the brake line assembly 32 is fixedly connected with the pull plate 3 on the bearing assembly 12 through screws, the brake wire 5 is driven by external force, pulls the pull plate 3 to slide to one end, and makes the impact assembly 31 lose its support and move downward. And under the action of the impact spring 16, the impact is realized, the reset assembly 33 is fixedly connected with the pull plate 3, and the pull plate 3 is pushed back by the reset spring 19.

[0023] The impact assembly 31 is composed of a pull ring 1, a guide post 2, a spacer 8, an impact spring 16, and a top screw 15. The pull ring 1 is rotatably installed on one end of the guide post 2, and ...

Embodiment 2

[0028] Embodiment 2: As shown in Figures 3, 4, and 6, the electromagnetic trigger mechanism is composed of an impact assembly 31, an electromagnet assembly 24, a wiring assembly 25, and a bearing assembly 12. The impact assembly 31 is pressed on the bearing assembly 12 by an impact spring. The pull plate 3 is supported by the pull plate 3, and the armature 30 of the electromagnet assembly 24 is fixedly connected with the pull plate 3 through screws. When the electromagnet 34 generates electromagnetic force in the energized state, the electromagnetic force makes the pull plate 3 move to one end , open the lock hook 14 to realize impact.

[0029] The impact assembly 31 is composed of a pull ring 1, a guide post 2, a spacer 17, an impact spring 16, and a top screw 15. The pull ring 1 is rotatably installed on one end of the guide post 2, and the guide post 2 extends into the shock spring 16, and the spacer 17 is sleeved outside the shock spring 16, and the spacer 17 and the guide...

Abstract

A brake for the traction cable of elevator has a trigger mechanism, which is composed of an impact module, an electromagnetic module, a connecting string module, and a bearing module. The pull plate on bearing module is pressed by said impact module via impact spring. Said pull plate is connected with electromagnetic module and is moving toward one end under the action of electromagnetic module to implement impact. A restoring spring can restore the pull plate to original position.

Description

technical field [0001] The invention belongs to the manufacturing field of an elevator overspeed protection device, in particular to a trigger device for an elevator traction rope brake. Background technique [0002] The elevator traction rope brake provides a guarantee for the safe operation of the elevator. Chinese Patent No. 01274866.8 provides an elevator traction rope brake, which can effectively perform balanced braking and implement overspeed protection when the elevator goes up and down over speed. The trigger mechanism of this patent is composed of a lock hook frame, a lock hook and a coaxial brake wire. The trigger of the lock hook is a mechanical signal obtained from the two-way speed limiter through the coaxial brake wire. When the elevator car exceeds the speed, the speed limiter will act. Drive the coaxial brake line to pull the lock hook, release the sliding shaft to drive the brake lining to move, and then clamp the traction rope ...
