Abstract

The invention discloses a step chain tensioning structure of an escalator. The step chain tensioning structure of the escalator comprises a tensioning rod fixed on a tensioning shaft, and an elastic member which is arranged between the tensioning rod and a truss and is capable of providing the tensioning rod with an elastic restoring force to tension the step chain, wherein by adopting the step chain tensioning structure, the tensioning rod drives the tensioning shaft to move so as to enable the step chain to tension again under the action of the elastic restoring force of the elastic member when the step chain is loose; and a switch baffle on the tensioning rod does not trigger the switch at the moment, and the escalator is allowed to run normally. Therefore, the automatic tensioning function of the step chain is realized. However, when the step chain is too loose, the elastic restoring force of the elastic member further functions to enable the tensioning rod to do further motion, so that the switch baffle on the tensioning rod triggers the switch, and the switch acts to enable the escalator to stop moving so to realize a protection function.

Description

[0001] technical field [0002] The invention relates to a step chain tensioning structure of an escalator. [0003] Background technique [0004] In the prior art, the cascade chain is artificially tightened, which needs to be tightened regularly, and there are many uncertain factors due to manual operation, and there is a possibility that the cascade chain is in a slack state due to various human reasons. [0005] Contents of the invention [0006] The object of the present invention is to provide an automatic tensioning structure for the step chain of an escalator, and when the step chain is excessively loose, the escalator will be stopped in time. [0007] In order to achieve the above object, the technical solution adopted by the present invention is: a step chain tensioning structure of an escalator, comprising a tensioning shaft extending along the width direction of the escalator, mounted on the tensioning shaft for all The sprocket that the step chain rotates a...
