Anti-falling speed reduction device for building construction elevator and using method of anti-falling speed reduction device

Abstract

The invention provides an anti-falling speed reducer for a building construction elevator and a using method of the anti-falling speed reducer, and belongs to the technical field of elevators. Comprising a base, a bridge box and a fixed lifting device, the top of the base is fixedly connected with a supporting frame, the fixed lifting device is fixedly connected to the top of the supporting frame and connected with the bridge box through a cable, the top of the base is fixedly connected with a pair of guide rods, and the pair of guide rods is fixedly connected with the bridge box. The top ends of the pair of guide rods are fixedly connected with the supporting frame, and the guide sleeve assemblies are fixedly connected to the top of the bridge box through a pair of mounting plates. By arranging the first speed reduction assembly and the second speed reduction assembly, a rubber pad, a fixing ring and a sliding rail are pushed to move close to a guide rod, the rubber pad extrudes the surface of the guide rod to generate sliding resistance so as to reduce the falling speed of an axle box, and finally the buffer assembly is used for unloading force, so that the axle box stably falls to the ground; therefore, the personal safety of the elevator passengers is protected.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an anti-fall deceleration device for building construction elevators and a use method thereof. Background technique [0002] During construction on a construction site, it is often necessary to use a vertical elevator for transportation to transport goods to high-rise buildings for construction. If an accident occurs during the operation of the vertical elevator, such as the failure of the servo motor of the lifting equipment, the shaft of the winding wheel will idling , the elevator bridge box will fall at the speed of free fall, which will pose a threat to the life safety of the ladder riders. [0003] The existing elevator technology has taken measures to prevent accidents, such as adding a second brake mechanism in the lifting equipment in advance, and when the reel shaft is idling, the brake mechanism is used to perform multi-stage braking on the reel shaft. Similar to po...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an anti-fall deceleration device for building construction elevators and its use method to solve the existing problems, which can provide sliding resistance during the sliding process of the axle box, slow down the speed of the slide, and at the same time make the axle box Landing smoothly at an appropriate speed to protect the personal safety of the elevator riders
