Elevator hydraulic buffer resetting performance dynamic measuring method and tester adopted by method

Abstract

The invention provides an elevator hydraulic buffer resetting performance dynamic measuring method. The measuring method comprises the following steps of first, measuring an initial distance between a blocking plate and the ground of an elevator bottom pit; second, measuring a distance between the blocking plate and the ground of the elevator bottom pit; third, judging whether an elevator car goes down or not and whether the elevator car is contacted with an elevator buffer; fourth, measuring a distance between the elevator car and the elevator bottom pit; fifth, judging whether the elevator car goes up or not; sixth, judging whether the elevator buffer finishes resetting; and seventh, processing data to obtain resetting time of the elevator buffer and analyzing the resetting performance of the elevator buffer. The measuring method can quickly and accurately measure the resetting time of the buffer, ensures the buffer to meet the safety requirement, and accordingly improves the measuring accuracy and the work efficiency of inspectors. The invention further provides a tester adopted by the method. The tester is simple in installation and meets the requirements of newly adopted elevator inspection procedures.

Description

technical field [0001] The invention relates to the technical field of elevator detection, in particular to a method for measuring the dynamic reset performance of an elevator hydraulic buffer and a tester thereof. Background technique [0002] The detection of the reset performance of the elevator buffer is the detection of the entire dynamic process of the reset after the buffer is compressed. Among them, the detection of the reset time of the elevator buffer is a mandatory inspection item in the elevator inspection rules and elevator manufacturing and installation standards; And in the elevator supervision and inspection process, the detection of the elevator buffer reset time is one of the basis for judging the safety status of the elevator, and the accuracy of measuring the elevator reset time can directly affect the judgment of whether the elevator is safe or not. [0003] When inspecting the reset time of the elevator buffer, considering the personal safety of the ins...

Problems solved by technology

Although testers for detecting the reset time of elevator buffers have been developed in China, the compressed images of the buffers depicted by these testers start from the time when the car touches the buffers, and the moment when the car is lifted cannot be truly confirmed, so Existing testers are not suitable for the newly implemented elevator inspection rules

At the same time, the originally developed tester failed to automatically identify the situation where the elevator buffer was kept at the maximum compression state due to a jamming fault, resulting in errors in the measurement results

Moreover, the commonly developed elevator buffer reset time testers are basically aimed at the test item itself, that is to say, the measured data is the reset time, and does not fully reflect the entire dynamic process of elevator buffer reset.

At this stage, there is no tester that can monitor the entire action and reset process of the elevator buffer, and provide analysis data for the cause of the buffer's action jamming or reset timeout.
