A cable transposition erection structure in a subdivided cable tunnel

Abstract

The invention discloses a cable transposition erection structure in a subdivided cable tunnel, which comprises a bottom plate, a vertical plate, a horizontal plate, a transition structure, a sliding structure, a chute, a layered position-limiting structure, and a stretching wire-receiving structure. The two ends of the top side of the vertical board are respectively vertically installed with vertical boards, the tops of the two vertical boards are welded with horizontal boards, the bottom side of the horizontal boards is provided with transitional structures, and one side of the vertical boards is provided with a chute. One side of the vertical plate is equipped with a sliding structure, and the upper and lower sides of the sliding structure are respectively equipped with a layered limit structure and a stretching wire take-up structure. Through the layered limit structure, various wire harnesses are placed in the separation Then, with the cooperation of the second positioning pin, the closing plate is fixed on the side of the layered seat, and the rubber pad is used to squeeze and fix the cable, which can realize the arrangement and fixing of the cables. With the cooperation, it is possible to sort out, classify and fix various cables to ensure clear lines and reduce the occurrence of danger.

Description

technical field [0001] The invention relates to the technical field of grid erection, in particular to a cable transposition erection structure in a subdivided cable tunnel. Background technique [0002] With the acceleration of urbanization and the continuous improvement of people's requirements for quality of life, there are more and more restrictions on the use of overhead transmission lines, and more cables will be used for new transmission channels; There will be a large number of overhead transmission lines for underground transformation, and new cable channels for laying; [0003] When the transmission line is laid by cables, the main workload and investment are the construction of civil channels. Therefore, under the premise of determining the cable laying method, reducing the section size and reducing the occupied area can effectively save engineering investment. In order to improve the reliability of power supply, power cables can be used Different passages or sub...

Problems solved by technology

[0003] When the transmission line is laid by cables, the main workload and investment are the construction of civil channels. Therefore, under the premise of determining the cable laying method, reducing the section size and reducing the occupied area can effectively save engineering investment. In order to improve the reliability of power supply, power cables can be used Different passages or subdivided tunnels are used for laying. Because subdivided cable tunnels can share part of the wall, reducing the width of the land, and at the same time, the relevant procedures can be completed at one time, and the external coordination workload is relatively small. In urban cable passages, subdivided There will be more and more cabin tunnel applications. At present, there are many problems in the design of sub-compartment cable tunnels, which is not convenient for the use, operation and maintenance of cable tunnels;

[0004] For the problem of cable laying and transposition, due to the large diameter of the cable, the transposition of the through-wall casing is not conducive to the laying of the cable. Because the cables cross at the transposition and the opening is a weak link, the cables cannot be isolated, posing safety hazards and low reliability. At the same time, if the cables pass through the pedestrian aisle during transposition, it will affect the passage of personnel
