Elevator safety and synchronous self-rescue device

Abstract

The invention provides an elevator safety and synchronous self-rescue device. The elevator safety and synchronous self-rescue device is characterized by comprising an elevator car synchronizer, a self-rescue device and a synchronous detecting device, wherein the elevator car synchronizer is connected with an elevator car through a rack on a lifting guide rail; the self-rescue device is connected with the elevator car synchronizer through a clutch; and one end of the synchronous detecting device is connected with the elevator car, and the other end is connected with a fixed part of the elevator car synchronizer. The synchronous operation of the elevator safety and synchronous self-rescue device and the elevator car is realized; the elevator car is accurately positioned; persons trapped in an elevator can realize self rescue through manually driving the elevator to a safety position or an exit under the condition of not damaging the elevator car on occasions of power failure, rupture of an elevator lifting rope or other elevator faults; and meanwhile, the operation stability of the lifting rope of the elevator car can be judged to a certain extent. The elevator safety and synchronous self-rescue device is high in efficiency and small in time consumption, saves the manpower, the material resources and the financial resources, timely rescues persons trapped in the elevator, and guarantees the safety of the trapped persons.

Description

technical field [0001] The invention belongs to an elevator self-rescue device, in particular to an elevator safety and synchronous self-rescue device. Background technique [0002] Elevator refers to the mechanical and electrical equipment that is driven by power and uses a box running on a rigid guide rail or a ladder running along a fixed line to lift or transport people and goods in parallel. With the rapid development of modern industry, the application of elevators is increasing day by day, but the accompanying problems are also becoming more and more prominent. For example: elevator safety gear slips, elevator falls during high-speed descent or ascent, etc. The number of elevator safety accidents caused by this is increasing day by day. Usually, people who take elevators are closed in the elevator car due to elevator failure, which brings great harm to life safety. Great danger. [0003] In order to solve the above-mentioned problems, the methods for rescuing people...

AI Technical Summary

Problems solved by technology

[0005] The invention provides an elevator safety and synchronous self-rescue device, which overcomes the existing technology of rescuing trapped people in elevators, which not only consumes a lot of manpower, material resources, and financial resources, but also has low efficiency and takes a long time. There are great hidden dangers to safety, and at the same time, it may cause irreversible damage to the elevator and other defects
