Problems solved by technology

[0006] However, if the wire slot installation method with the opening of the wire slot facing downward is adopted, when arranging the cables in the wire slot, it is necessary to operate from below, that is, to work with the head up, the work intensity is high, and the operation is inconvenient. The effect of gravity can also easily cause the cable to be uneven and affect the quality of wiring

Embodiment Construction

[0012] First, a brief description will be given of the "wire duct" of the present invention. The trunking can be a long shell used for placing wires and signals in railway vehicles, generally including a trunking body and a trunking cover, and one side of the trunking body forms an opening, that is, from the perspective of the cross section, the trunking body It is generally in the shape of a "U", and the trunking cover is buckled on the opening of the trunking body, so that the cross section of the entire trunking is "mouth"-shaped to fully protect the cables inside. Wherein, the trunking body is generally a metal stamping part, the trunking cover is made of insulating material, and the connection relationship between the trunking body and the trunking cover can be a common method in the field, which is not particularly limited in the present invention.

Abstract

The invention provides an auxiliary tool for mounting a railway vehicle line slot. The auxiliary tool comprises a supporting base for supporting the auxiliary tool on the ground, carrier roller assemblies are arranged at two ends of the supporting base respectively, first turnover supports are supported on the carrier roller assemblies, second turnover supports are detachably arranged on the first turnover supports, outer contours of the first turnover supports and the second turnover supports make a circle, first grooves and second grooves are formed in the tops of the first turnover supports and the bottoms of the second turnover supports respectively and enclose a through hole, the line slot longitudinally penetrate the through hole, and mounting components for fixedly mounting the line slot are fixedly arranged on the first grooves. The auxiliary tool for mounting the railway vehicle line slot can meet the assembly requirement of line slot opening orientation, head raising operation in the wiring process is avoided, operation is facilitated, labor intensity is reduced, and wiring quality is further ensured.

Description

technical field [0001] The invention relates to the manufacturing technology of railway vehicles, in particular to an auxiliary tooling for installing railway vehicle trunking. Background technique [0002] In the railway vehicle body, various cables (including electric wires and signal lines, etc.) need to be routed uniformly, usually through the bottom of the car body, and extend to various preset positions in the car body. [0003] In the prior art, the wire trough is generally hoisted under the beam of the chassis, and the top opening of the wire trough faces upwards; when wiring, it is only necessary to place the wire trough on the wiring platform with the opening facing upwards, and arrange the cables to the wires. In the trough, buckle the wire trough cover to the opening of the wire trough, and then directly lift the assembled wire trough to the beam at the bottom of the car body. [0004] Since the trunking is generally a metal sheet metal part, the trunking cover ...
