An elevator speed limiter safety gear linkage test platform

Abstract

The invention relates to an elevator speed governor safety gear linkage test platform. It includes: a bracket with two vertical guide rails; a test frame for simulating the movement of the car, with a first guide shoe on the test frame; a speed limiter for detecting whether the test frame is overspeed; and The safety gear linked with the speed limiter; the lifting frame, which is provided with a second guide shoe to make the lifting frame move up and down along the direction of the guide rail, and the lifting frame is located above the test frame; the lifting mechanism for driving the lifting frame to rise; The hook mechanism for automatic decoupling is set between the lifting frame and the test frame. The lifting frame and the test frame are hooked together by the hook mechanism and rise together under the drive of the lifting mechanism. When the lifting frame and the test frame rise together to a certain height , The hook mechanism is automatically unhooked to separate the lifting frame from the test frame, and the test frame is released and freely falls along the direction of the guide rail. The invention is simple in structure, easy to implement, occupies less space, and is more suitable for teaching and training.

Description

Technical field [0001] The invention relates to an elevator speed limiter safety gear linkage test platform. Background technique [0002] An elevator is a vertically-lifting transportation device used to carry passengers or goods. The existing elevators for use are composed of eight major systems such as guidance, traction, car, door, balance, safety, drag, and control, and are distributed in hoistways, machine rooms, landings and other places. With the development of economy and society, elevator professional and technical personnel are far from meeting the needs of the elevator market. In order to meet the needs of the market, some colleges have set up elevator majors to cultivate elevator professional and technical personnel. [0003] However, because real elevators cannot implement all the traction leads to break, during the teaching process of the linkage test of the overspeed governor and safety gear for car free fall overspeed, the principle of linkage of elevator overspe...

Problems solved by technology

[0003] However, since the real elevator cannot break all the traction wires, during the teaching process of the linkage experiment between the speed limiter and the safety gear of the free fall of the car, it is impossible to directly reflect the linkage principle of the safety gear of the elevator speed limiter and the principle of the elevator brake. Meet the teaching and training requirements
