Example Embodiment

[0024] The present invention will be further explained below in conjunction with the drawings.

[0025] in figure 1 In this case, the tension roller connector 1 has been installed on the vertical support 8 and the diagonal brace 15 of the truss through the positioning device 11, and the tension roller 9 has also been installed on the connector 1, and the tension roller 9 is against The pressing handrail belt 14 is on the friction wheel 13. Due to the accurate positioning of the connecting member 1 by the positioning device 11, the arc of the installed tensioning roller 9 is concentric with the arc of the handrail belt 14 and the handrail belt friction wheel 13, and The width center of the tensioning roller 9 coincides with the width center of the handrail belt 14. The specific structure of the positioning device 11 and the method of installing and positioning the connecting member 1 will be described in detail below.

[0026] See Figure 2-5 As shown, the positioning device 11 ...

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...
