Embodiment 1
[0036] Such as Figure 1-4 As shown, this embodiment provides an electrically controlled safety gear trigger device, which mainly includes a main shaft 1 , a trigger component 2 , an action component 3 and a reset component 4 .
[0037] Specifically, in this embodiment, a lifting rod 5 is provided on the main shaft 1, and the end of the lifting rod 5 is connected with the safety gear wedge 6, so that when the main shaft 1 rotates, the lifting rod 5 is driven. When the pull rod 5 moves, the safety gear wedge 6 promotes the locking of the safety gear to realize the braking of the car.
[0038] As a preferred solution, several swing rods 11 are arranged on the main shaft 1 , and the starting end of the lifting rod 5 is arranged on the swing rods 11 . Since the connection point between the swing rod 11 and the lifting rod 5 will be far away from the axis of the main shaft 1, the setting of the swing rod 11 can amplify the rotation effect of the main shaft 1, and in the actual app...

The invention belongs to the technical field of elevator speed limiting equipment, and provides an electric control type safety tongs triggering device. The electric control type safety tongs triggering device comprises a main shaft, a triggering assembly and an action assembly, wherein the main shaft is rotationally arranged on a car frame, and the triggering assembly and the action assembly are arranged on the main shaft; a lifting rod is arranged on the main shaft, and the tail end of the lifting rod is connected with a safety tongs wedge block; the triggering assembly comprises a magnetic attraction part and an electromagnetic part, the magnetic attraction part is arranged on the main shaft and synchronously rotates with the main shaft, and the electromagnetic part is correspondingly arranged on the rotating track of the magnetic attraction part; the action assembly comprises a torsion spring which is arranged on the periphery of the main shaft in series, the exterior of one end of the torsion spring is fixedly arranged, and the other end of the torsion spring is fixedly connected with the main shaft; and when the magnetic attraction piece moves towards the electromagnetic part, the main shaft stretches or compresses the torsion spring. According to the electric control type safety tongs triggering device, the occupation of the safety tongs device on the hoistway space can be effectively reduced, the input cost is reduced, and debugging and maintenance are more convenient.
Description
technical field [0001] The invention belongs to the technical field of elevator speed-limiting equipment, and in particular relates to an electric control type safety gear trigger device. Background technique [0002] At present, the mechanical speed governor-safety gear system, as one of the traditional elevator safety devices, is widely used in various types of elevators. When the elevator overspeeds, runs out of control, or the suspension device breaks, the speed limiter moves quickly to trigger the safety gear for linkage to stop the elevator car on the guide rail and keep it stationary, thereby avoiding casualties and equipment damage accidents. [0003] However, the above-mentioned traditional mechanical overspeed governor system is complex in composition, needs to occupy a large space in the hoistway, and is cumbersome to debug and maintain, and the investment cost is high. Contents of the invention [0004] In order to overcome the above-mentioned shortcomings of ...
