Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] As recorded in the background technology, it is very important to utilize (recycle) old indoor equipment in the existing cable construction of the railway signal profession in the prior art, and it is difficult to recycle the old equipment of the distribution board (distribution device). The difficulty is that without stopping the operation of the existing equipment, the newly installed outdoor cables are brought into the room to overlap with the terminals of the existing distribution board. Occupy the space and position that do not have new cable construction, if carry out one-time replacement of old and new cables according to the conventional method, it will take 7 hours of operation ...

Abstract

The invention provides a cable replacing method of a branching device. The cable replacing method comprises the following steps of a classifying step: classifying the type of each existing cable in the branching device, classifying the existing cables in the branching device according to the types, so as to obtain a plurality of existing cable groups; a selecting step: selecting one or more of a plurality of existing cable groups as a selected cable group; a pre-constructing step: enabling the selected cable group to be detached from a terminal of the branching device, enabling the detached selected cable group to penetrate into a hole in the shell of the branching device, and then enabling the selected cable group penetrated in the hole to be installed on the terminal corresponding to theselected cable group; and a construction step, wherein a new cable which is the same as the selected cable group is introduced into the branching device from a cable mounting port of the shell of thebranching device, the selected cable group is detached from the terminal of the branching device, and the new cable is installed on the terminal corresponding to the selected cable group, so that thereplacement error caused by mutual confusion of the new old cables is avoided, the replacement efficiency is improved, and the replacement time is shortened.

Description

technical field [0001] The invention relates to the technical field of railway cable replacement, in particular to a cable replacement method for a branching device. Background technique [0002] The utilization (recycling) of old indoor equipment is very important in the existing cable construction of the railway signal profession, and it is difficult to reuse the old equipment of the distribution board (distribution device). The difficulty is that without stopping the operation of the existing equipment, the newly installed outdoor cables are brought into the room to overlap with the terminals of the existing distribution board. Occupy the space and position that do not have new cable construction, if carry out one-time replacement of old and new cables according to the conventional method, it will take 7 hours of operation time, which cannot meet the requirements of the train opening time. Contents of the invention [0003] The main purpose of the present invention is ...
