Escalator stair chain tensioning detecting device

Abstract

The invention discloses an escalator stair chain tensioning detection device. The detecting device comprises a tensioning force detector, wherein the tensioning force detector is fixed at the end, extending along the length direction of an escalator in a stair chain tensioning device, of a sliding rail, the signal input end of the tensioning force detector is fixedly connected with the end part ofa tensioning rod of a tensioning detection device, and the signal output end of the tensioning force detector is connected with an escalator controller through transmission lines. Compared with the prior art, the escalator stair chain tensioning detection device can detect the tensioning force of a left stair chain and a right stair chain in real time, when the tensioning force exceeds or is smaller than a set reference tension value, the escalator controller can give an alarm to remind the maintenance personnel to check whether the stair chains are too tight or too loose, after the escalatorcontroller gives an alarm, an escalator cannot be normally started, the degree of tightness of the stair chains needs to be adjusted by the stair chain tensioning device, so that the escalator can benormally started until the escalator is in a safe state, and unnecessary casualties or faults can be avoided.

Description

technical field [0001] The invention relates to the field of a step chain tension detection device, in particular to a step chain tension detection device used for escalators and moving walks. Background technique [0002] With the rapid development of social economy and the continuous improvement of people's living standards, escalators and moving walks have become an indispensable part of people's daily life, and more and more appear in people's daily life scenes. In public places such as shopping malls and public transportation. [0003] After the escalator or moving walk has been used for a period of time, the step chain will loosen or even break. The existing step chain tightening device relies on manual tightening, which needs to be tightened regularly, and there are many uncertain factors due to manual operation. There is a possibility that the ladder chain is in a slack state due to various artificial reasons. Therefore, the tensioning device is an important part o...
