Integrated wire groove with hinge

Abstract

The invention provides an integrated wire groove with a hinge. A wire groove is installed on a vehicle body of a railway passenger car and is used for a railway passenger car layout line. The wire groove comprises a groove body and a groove cover. The groove body and the groove cover are connected through a hinge. The groove cover can rotate around the hinge. The groove body is connected to the free side of the groove cover. The groove body is provided with the groove cover which can be rotated to be opened or closed from the groove body. When the line is laid and when the line is repaired or maintained, the groove cover is opened, after the line installation is completed or after the repair and maintenance are completed, the groove cover and the groove body are closed, and the operation is convenient.

Description

technical field [0001] The invention relates to an integrated trunking with hinges, and belongs to the technical field of electrical wiring structures for railway passenger cars. Background technique [0002] The wiring of railway passenger cars generally uses wire grooves to protect the wire harness. There are two wiring methods, modular wiring and loose line wiring. When wiring loose wires, install the wiring trough behind the vehicle, and then arrange the wiring harness to the wiring trough and the bus; modular wiring is to pre-arrange the wiring harness in the wiring trough, and then install it on the vehicle. [0003] The groove body and the groove cover of the existing railway passenger car wire groove are of split structure, and are fixed by two rows of bolts. The slot structure of the two wiring modes is consistent. [0004] When carrying out loose line wiring in a new passenger car, it is necessary to remove the slot cover first, and then install the slot cover a...

Problems solved by technology

In this process, affected by other factors such as gravity and improper storage, the tank cover is easily deformed, resulting in horizontal or vertical misalignment of the mounting holes of the tank cover and the tank body. Since there are two rows of mounting holes, once the dislocation direction is inconsistent, it will The tank cover cannot be installed smoothly on the tank body

[0005] During the maintenance and overhaul at each stage after the train is put into use, when it is necessary to overhaul and maintain the wire harness in the wire slot, the slot cover also needs to be removed. The number of bolts is large, and the operation of disassembly, installation and maintenance of the existing vehicle is very difficult, which brings great obstacles to the maintenance of the wiring harness.
