Problems solved by technology

[0002] The escalator has two step chains, which are respectively connected to the two ends of the steps. The step chains will relax after a period of use, so generally a tensioning mechanism is provided to tension the step chains. The existing tensioning mechanism is pulled by a tension spring. The sprocket of the two step chains is re-tensioned under the tension of the tension spring when the step chain is relaxed. However, in the general tensioning mechanism, the two step chain sprockets are independently tensioned, and the two steps cannot be guaranteed. The root cascade chains are tensioned synchronously, which can easily lead to the inclination of the cascades and lead to safety accidents

Embodiment Construction

[0021] The present invention provides a step chain tensioning frame of an escalator. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] In this paper, the rear refers to the moving direction of the carriage when the compression spring is stretched; the front refers to the moving direction of the carriage when the compression spring contracts.

[0023] see Figure 1-3 , the present invention provides a step chain tensioning frame of an escalator, comprising two supporting guide rails 1 arranged in parallel, a carriage 2 slidably arranged on the two supporting guide rails, and a connecting shaft rotatably arranged on the carriages 3. The step ch...

Abstract

The invention provides a stair chain tensioning frame for an escalator. The stair chain tensioning frame comprises two supporting guide rails arranged in parallel, a sliding frame arranged on the twosupporting guide rails in a sliding manner, a connecting shaft arranged on the sliding frame in a rotating manner, stair chain wheels arranged at the two ends of the connecting shaft, and two compression springs. The two sides of the sliding frame abut against the inner side faces of the two supporting rails correspondingly. The two compression springs are symmetrically arranged and are parallel to the supporting guide rails, the ends of the compression springs are fixedly connected with the sliding frame, and the other ends of the compression springs are fixedly connected with a fixing frameof the escalator. The tensioning frame can ensure that the two stair chains are tensioned synchronously, and stair falling is prevented.

Description

technical field [0001] The invention relates to the technical field of escalators, in particular to a step chain tensioning frame of an escalator. Background technique [0002] The escalator has two step chains, which are respectively connected to the two ends of the steps. The step chains will relax after a period of use, so generally a tensioning mechanism is provided to tension the step chains. The existing tensioning mechanism is pulled by a tension spring. The sprockets of the two step chains are re-tensioned under the tension of the tension spring when the step chains are relaxed. However, in the general tensioning mechanism, the two step chain sprockets are independently tensioned, and the two cannot be guaranteed. The root cascade chains are tensioned synchronously, which can easily cause the cascades to tilt and lead to safety accidents. [0003] It can be seen that the prior art still needs to be improved and enhanced. Contents of the invention [0004] In view...
