Remotely and manually reset rope gripper device of elevator

Abstract

The invention discloses a rope clamp device capable of remote and manual reset for an elevator, which is characterized in that it includes a base for fixing on a mechanical beam to enable the traction rope to stop at a position, the base is provided with an outer cover, and the inner side of the outer cover is provided with a For the fixed wedge and movable wedge used for braking the main steel cable, the fixed wedge is fixed inside the outer cover, and the movable wedge can slide up and down relative to the base; one end of the reset cable is fixedly connected with the movable wedge; the limiter One end of the cable is connected to the speed limiter, and the other end is provided with a bolt for limiting the movable wedge. The bolt is arranged in the bolt fixing seat, and a spring is arranged between the bolt and the bolt fixing seat, and the bolt is exposed from the bolt fixing seat. The lower side of the end is a slope structure extending outward and upward, and the movable wedge is provided with a hole matched with the latch. After the upward overspeed rope gripper of the elevator moves, using this device, the maintenance personnel can conveniently, safely and effectively reset the rope gripper without approaching the car or counterweight to restore the elevator to normal operation.

Description

technical field [0001] The invention relates to a rope clamp device that can be manually reset remotely for an elevator, and in particular to a kind of when the elevator's upward overspeed rope clamp operates, the maintenance personnel do not need to approach the car or counterweight it conveniently, safely and effectively. The utility model relates to a device for restoring an elevator to normal operation, and belongs to the technical field of elevators. Background technique [0002] At present, most elevators need to adopt the machine room-less installation structure due to the building itself. When the geared traction machine is used, the elevator's upward overspeed protection device is mainly a rope clamp. But after the elevator goes up overspeed and makes the rope gripper stop the car through the action of the speed limiter, the traditional rope gripper mechanical reset must be entered into the hoistway by maintenance personnel, and the rope gripper is reset using a spe...

AI Technical Summary

Problems solved by technology

However, after the elevator goes up over speed and the speed limiter acts to make the rope clamp stop the car, the traditional mechanical reset of the rope clamp must be performed by maintenance personnel entering the hoistway and using a special tool to reset the rope clamp.

As a result, maintenance personnel are slow to save people, difficult to reset, and there are potential safety hazards; in addition, according to the 9.10. When releasing, there shall be no need to approach the car or counterweight
