Method for changing connecting component part of steps escalator and apparatus for guiding it out of rail

Abstract

Disclosed is a replacing method of escalator step link and its guide rail device. All steps of an escalator are removed, and likewise a landing plate of a lower machine room is removed away, while a guide rail device is set up in a range from an inner rail of the lower machine room to a landing, and a dummy shaft is attached to both ends of a disconnected step link, then this step link at the side of the inner rail is placed on the guide rail device, drawing this step link up to a holding guide rail on the landing and this drawn step link is replaced with a new step link, restoring it the original position, whereby both ends of the step link are connected to each other and the endless-form step link is operated up to the next replacement position.

Description

technical field [0001] The invention relates to a replacement method of an escalator step connector and a used lead-out guide rail device, in particular to a replacement method of an escalator step connector capable of shortening working time. Background technique [0002] With regard to an escalator, a plurality of step connectors connected in a ring are guided along a drive rail by guide wheels, whereby the treads circulate, and when the step connectors are worn out, the step connectors must be replaced. For this reason, it is necessary to dismantle several connecting bolts of the step connector, and at this time, the operator has to perform the following operations, that is, remove the ground panel at the escalator boarding place, enter the mechanical room to remove the connecting bolts, and remove the escalator from the guide rail. Remove the step connecting piece, and then place it on the ground of the ladder by hand. [0003] In recent years, escalators have been inst...

Problems solved by technology

[0010] According to the method in the prior art, when replacing the step connectors of the escalator, such operations will be repeated, and the operator must enter the narrow and narrow machine room with harsh working environment, remove the connecting bolts in an uncomfortable posture, and remove the connecting bolts from the escalator. Remove the heavy step connectors from the guide rails and place them on the ground at the landing

As a result, the replacement work of the step connector of the escalator is difficult and takes a long time

[0011] In the replacement method of the step connector of the escalator of the above-mentioned prior art, because the replacement of the step connector is performed in or near the lower mechanical room, the replacement operation cannot be carried out by 2 to 3 people at the same time, thereby causing Solved the problem that the operation time is very long, and the operation and stop time of the escalator are also very long

In addition, because the working place in the lower mechanical room is narrow, the weight of the three step connectors varies depending on the model, but even a light step connector weighs about 40kg, so there is a safety hazard for the workers. sexual problems
