Problems solved by technology

[0003] The traditional escalator speed measurement device mainly relies on manual hand-held detection. Later, with the development of science and technology, escalator speed detection instruments have gradually appeared, but the technology is not yet mature.
The existing step speed measuring device has problems such as complicated operation and unstable structure, which makes the measurement impossible to be carried out effectively and reliably.

Abstract

The invention provides an escalator stair power-off fault detection device which comprises a supporting rod component and an elastic compression component. The supporting rod component comprises a plurality of supporting rods and two universal hooves; the elastic compression component comprises a sliding block, an encoder, an installation plate, a torsional spring, a torsional spring installation plate and the like. According to the escalator stair power-off fault detection device, the supporting rods can be firmly supported on a left lateral plate and a right lateral plate of an escalator, and the encoder is completely in contact with stairs; the firmness of a speed measuring clamp during clamping is accordingly and greatly improved. The escalator stair power-off fault detection device is used in cooperation with the speed measuring clamp arranged on a handrail, the synchronism of the stairs and a handrail belt can be rapidly and conveniently detected, and the efficiency is greatly improved. The escalator stair power-off fault detection device has the advantages of being convenient to detect, high in speed, high in accuracy, high in universality and the like.

Description

technical field [0001] The invention relates to a power failure detection device for steps of an automatic escalator. Background technique [0002] With the increase of high-rise buildings, escalators have increasingly become an indispensable means of transportation in people's daily life. In the process of using escalators, its safety has attracted more and more attention. Therefore, efforts must be made to improve the performance of the escalator system to ensure that the escalator is efficient, energy-saving, safe and reliable. The performance safety of the escalator is mainly reflected in the braking ability of the escalator when it fails, so how to effectively measure the braking ability of the escalator is an important direction in the performance testing of the escalator. The important basis for testing the braking capacity of the escalator is to test the running speed of the escalator after power failure, and the braking capacity of the escalator can be judged by a...
