Removal and installation support jig for follower roller pressing device

Abstract

The invention provides a dismounting and mountin support fixture for a driven roller pressing apparatus. The dismounting and mountin support fixture can prevent a spring or a spring bracket from falling into the inside of a truss upon dismounting and mounting the driven roller pressing apparatus which includes a lever which retains a driven roller, a spring which applies force to the lever, and a spring bracket of a reception spring. The dismounting and mounting support fixture is used when a driven roller pressing apparatus (12) which is included in a handrail driving apparatus (9) of an automatic elevator (1) and presses a driven roller (12c) on a handrail (3) is dismounted or mounted in relative arrangement on a base plate (10) of the inside of a truss (2). The dismounting and mounting support fixture comprises: a first flat portion (13a) which abuts against an upper portion of a front end portion (12b1) of the lever (12b); a second flat portion (13b) which abuts against a lower portion of a lower spring bracket (12f) of a lower end portion of a reception spring (12d); an erecting portion (13c) which connects the first flat portion (13a) and the second flat portion (13b), a notch portion (13d) is formed on the second flat portion (13b) for preventing interruption in a pushing bolt (12e).

Description

Technical field [0001] The present invention relates to a detachment and installation support clamp for a driven roller pressing device used when a driven roller pressing device is detached and installed. The driven roller pressing device is provided by a passenger conveyor and will be included in a driven roller of a handrail driving device. Press on the armrest. Background technique [0002] For example, a passenger conveyor such as an escalator is provided with a handrail driving device that drives a handrail. The handrail driving device includes a driving roller driven by a handrail driving chain, a driven roller, and a driven roller pressing device that presses the driven roller on the handrail by spring force. The armrest is arranged to be sandwiched between the driving roller and the driven roller to cyclically move. [0003] Since the material of the driven roller is rubber, its circle diameter decreases with aging or wear, so it must be replaced. In addition, the driven...

AI Technical Summary

Problems solved by technology

In the case of an escalator, because it has a slope, if the spring or the spring bracket falls into the slope, it will make the work more cumbersome

[0010] In addition, Patent Document 1 is silent on the lever holding the driven roller, the spring biasing the lever, and the spring bracket receiving the spring.

Therefore, there is no disclosure about the technology of preventing the spring and the spring bracket from falling into the interior of the truss when the driven roller pressing device with the spring for applying force to the lever and the spring bracket for receiving the spring is disassembled and installed.
