Moving handrail guiding assembly of guardrail column part of escalator or moving walking escalator

Abstract

The invention discloses a moving handrail guiding assembly of a guardrail column part of an escalator or a moving walking escalator. The moving handrail guiding assembly comprises a supporting formingpiece, and a low-friction-coefficient component or a low-friction-coefficient subcomponent chain, wherein the supporting forming piece is mounted on the guardrail column part and provided with a chamber defined by the side walls and the bottom; and the two ends of the low-friction-coefficient component or the low-friction-coefficient subcomponent chain are fixed to the guardrail column part, thelow-friction-coefficient component comprises a single component, the low-friction-coefficient subcomponent chain comprises a plurality of low-friction-coefficient subcomponents, the low-friction-coefficient component or each low-friction-coefficient subcomponent has the shape matched with the shape of the chamber of the supporting forming piece, and the ends of all the low-friction-coefficient subcomponents are connected mutually to cover an opening of the chamber. The moving handrail guiding assembly is simple in structure and low in cost, heat generated by friction and heat generated by repeated bending in a handrail can be reduced, the service life of the handrail is prolonged, abrasion, aging and cracking are reduced, and meanwhile, a sensor can be used for monitoring force in the handrail and monitoring abrasion of the handrail.

Description

technical field [0001] The present invention relates to sliding load bearing systems for handrails of escalators, and more particularly, to sliding load bearing systems for handrails of balustrade sections of escalators. Background technique [0002] The escalator handrail forms a closed-loop circular motion on the escalator railing between the upper stair transition landing and the lower stair transition landing. Armrests are usually manufactured from rubber material, attached to support moldings that give the armrest the required strength. The underside of the armrest usually has a laminated fabric cover which provides low friction over the usually metal support molding. [0003] Escalator railings are divided into straight sections and balustrade post sections. The balustrade post portion of the escalator railing is the curved section at each end of the escalator railing. On the straight part of the escalator balustrade, the handrail slides forward only under the force...

AI Technical Summary

Problems solved by technology

[0007] Due to the small bending radius of the rolling bearing in the prior art, the rolling bearing guide mechanism provides a small supporting area during the bending process of the handrail, so a large force is generated locally on the handrail, which is easy to cause wear of the handrail and shorten the service life of the handrail and bearings

Moreover, due to the large force of the rolling bearing, the handrail is prone to wear and peeling locally, and the bearing structure does not completely fill the cavity of the supporting molding, so the peeling debris and dust of the handrail are easy to collect between the rolling bearing and the underside of the handrail in the cavity , even some rubber powder from the armrest enters the inside of the rolling bearing, causing failure

Moreover, the large force between the rolling bearing and the handrail can cause thermal problems, high noise and bearing misalignment problems

And in order to prevent bearing failure, regular maintenance is required to clean spalling matter, such as fabric or rubber particles, which also increases personnel and labor costs
