Speed limiter test table for elevator and testing system thereof

Abstract

The invention discloses a speed limiter test table for an elevator, which belongs to the technical field of a monitoring device of an elevator component. The speed limiter test table for the elevator comprises a driving unit, a detection unit, a speed limiter fixing device and a rack. A driving wheel and a detection wheel lean against the circumferential edge of a rope wheel of a speed limiter. The driving unit further comprises a driving and adjusting mechanism which comprises a driving elastic thrust structure. The detection unit further comprises a detection adjusting mechanism which comprises a detection elastic thrust structure. The test table adopted for test has the characteristics of high precision and small error. The invention further discloses a speed limiter testing system which comprises an electric part and a mechanical part. The mechanical part uses the speed limiter test table for the elevator. The electric part controls the testing system to realize full process of test, and full-automatic data collection and result analysis. The speed limiter test table for the elevator and the testing system provided by the invention are beneficial to developing of the speed limiter for the elevator and the efficiency of delivery inspection of the speed limiter for the elevator and the accuracy of detection data of products are further greatly improved.

Description

technical field [0001] The invention relates to a monitoring device for elevator components, in particular to an elevator speed governor test bench 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 manual debugging, which has errors, and sometimes the action value is suddenly stopped due to the sudden stop of the speed limiter sheave, and the value displayed by the instrument is the value that has been decelerated, and the test needs to be restarted. [0003] In response to the above problems, another test instrument has been researched and developed. When in use...

Problems solved by technology

Although this kind of speed limiter test bench solves some of the problems existing in the first two test instruments, the O-belt used in this test test bench is a non-standard belt. There are many models of speed limiters on the market, and the cost of customizing the belt is relatively high. In addition, there is a great technical difficulty in the connection of the O-belt; secondly, the belt is elongated, which will inevitably lead to a certain hysteresis in the speed control between the drive unit and the speed limiter sheave, and there must be a lag in the measurement of the high-speed area. Large error; the curved arm of the test unit needs to be manually adjusted and pressed for each test, and the pressing force changes greatly. There is a large human factor in data collection, which is prone to errors

The operation steps such as connecting the belt and adjusting the mechanical arm are cumbersome

It also makes the test instrument inconvenient to use
