Elevator speed limiter testing platform and elevator speed limiter testing system suitable to different rope sheave diameters

Abstract

The invention discloses an elevator speed limiter testing platform suitable to different rope sheave diameters and belongs to the technical field of elevator part detection devices. The platform comprises a drive unit, a detection unit and a speed limiter fixing device, wherein the drive unit comprises a drive axle installation seat, a drive wheel height adjusting mechanism and a drive transmission mechanism. A drive wheel is close to a rope sheave gradually and is pressed on the circumference edge of the rope sheave through the adjustment of the drive wheel height, and the platform is suitable to different rope sheave diameters. The invention also discloses an elevator speed limiter testing system suitable to different rope sheave diameters. The system comprises an electric part and a mechanical part, wherein the mechanical part uses the elevator speed limiter testing platform, and the electric part controls the testing system to test the whole process, automatically collect data and analyze results. The platform and the system are beneficial to development and research of an elevator speed limiter, and the efficiency of delivery inspection of the elevator speed limiter and the accuracy of product detection data are improved greatly.

Description

technical field [0001] The invention relates to a monitoring device for elevator components, in particular to an elevator speed governor test bench suitable for different sheave diameters and a test system thereof. Background technique [0002] There are three main types of existing elevator speed limiter action speed testing instruments: the first is to use a special speed limiter in conjunction with a debugging electric drill to measure the electrical and mechanical action speed of the speed limiter. When in use, put the head of the special speed limiter in the pitch circle groove of the elevator speed limiter, and do not lose it. This method is manually adjusted, and needs to be manually adjusted for different sheave diameters, and the operation is cumbersome and has errors. [0003] Another method is to attach a small magnetic piece to the side of the speed limiter sheave, set the initial speed, input the pitch circle circumference of the speed limiter sheave, and start...

AI Technical Summary

Problems solved by technology

This kind of test bench has the following disadvantages: First, the O-belt used is a non-standard belt, and there are many models of speed limiters on the market. For different speed limiter sheaves, corresponding belts need to be customized, and the cost of custom-made belts In addition, the connection of the O-belt is more technically difficult; secondly, the crank arm of the test unit needs to be manually adjusted and compressed for each test, and the compression force changes greatly, and there are large human factors in data collection. , it is easy to produce errors; again, due to the cumbersome operation steps such as the connection of the belt and the adjustment of the mechanical arm

It also makes the test instrument inconvenient to use
