Positioning device for connecting parts of mounting tension carrier roller of handrail of escalator and method

Abstract

The invention discloses a positioning device for mounting connecting parts of a tension carrier roller of a handrail of an escalator and a mounting method. When the connecting parts of the tension carrier roller are mounted, end surfaces of second positioning columns in the positioning device are attached onto a concave surface of a base, end surfaces of third positioning columns are attached onto first perpendicular edges of the connecting parts, the connecting parts are positioned assuredly in width directions relative to the base, and width centers of the connecting parts can be assuredly coincident with the width center of the handrail when the tension carrier roller is mounted on the connecting parts in a follow-up process; and top end surfaces of the connecting parts at second side edges are flushed with a horizontal transverse line in the positioning device, accordingly, an arc of the tension carrier roller which is mounted via the connecting parts is assuredly concentric with an arc of the handrail and a friction wheel of the handrail, at the moment, first lateral edges of the connecting parts at first lateral edges and the second lateral edges are respectively attached onto an inclined support and a vertical support, and accordingly the connecting parts are positioned and mounted by means of welding.

Description

[0001] technical field [0002] The invention relates to a positioning device for installing a handrail tensioning idler connecting piece on an escalator, and also relates to a method for using the positioning device to install the handrail tensioning idler connecting piece. Background technique [0003] In the escalator, the arc of the tensioning roller must be concentric with the arc of the handrail and the friction wheel of the handrail, and the width center of the tensioning roller must coincide with the width center of the handrail, so as to ensure the stable movement of the tensioning roller Only when the handrail is pressed against the handrail can the handrail run well, so the tensioning roller must be positioned accurately when installing the tensioning roller. The tensioning roller is positioned on the vertical brace and the diagonal brace of the truss through the connecting angle iron. The requirement of accurate positioning must ensure the accurate positioning of...

Problems solved by technology

The connecting angle iron installed by the existing tensioning roller is positioned by the upper chord, vertical brace and diagonal brace of the escalator truss, but when the installation position of the handrail shaft where the friction wheel base is located is deviated, the positions of the vertical brace and diagonal brace There is a deviation, or when the position of the connecting angle iron of the tensioning roller is not at the same level as the position of the upper chord of the metal skeleton, and there is a measurement error, it is impossible to ensure the accurate positioning of the connecting angle iron, that is, the arc of the tensioning roller and the handrail belt cannot be guaranteed.
