Embodiment 1

[0035] figure 1 Shown in is a schematic structural diagram of the trunking provided by an embodiment of the present application; figure 2 Shown in is a schematic structural diagram of the crimping plate provided by an embodiment of the present application; please refer to Figure 1-Figure 2 .

[0036] This embodiment provides a trunking 10, which is installed in the carriage 20 of the rail vehicle and is used for fixing cables, so as to ensure that the carriage 20 can obtain electric energy from the electric locomotive or generator car for normal use in the carriage 20.

[0037] Specifically, such as figure 1 As shown, the wire slot 10 of this embodiment includes a slot body 100 and a wire pressing plate 200 .

[0038] Wherein, the tank body 100 includes a bottom surface 110 and two side surfaces 120 connecting the bottom surface 110, the bottom surface 110 and the side surfaces 120 are all arranged along the length direction of the compartment 20, the bottom surface 110 a...

Embodiment 2

[0051] This embodiment provides a carriage, which includes the trunking as described in the first embodiment above, and the trunking is fixedly arranged in the carriage along the length direction of the carriage.

[0052] In the compartment of this embodiment, since the wire trough described in the above-mentioned embodiment 1 is laid, multiple wire harnesses of the cable can be placed in multiple wire harness fixing grooves respectively, so that multiple wire bundles are arranged side by side and laid horizontally. It is beneficial to increase the carrying capacity of the cable and ensure the safety of driving.

Embodiment 3

[0054] This embodiment provides a rail vehicle, which includes a plurality of end-to-end carriages, wherein the carriages are as above.

[0055] Since the rail car of this embodiment adopts the car described in the second embodiment above, multiple wire harnesses of the cable can be placed in multiple wire harness fixing grooves respectively, so that multiple wire harnesses are arranged side by side, and the way of horizontal laying is as follows: It is beneficial to increase the carrying capacity of the cable and ensure the safety of driving.

Abstract

The embodiment of the invention provides a wire duct, a carriage and a railway vehicle, the wire duct comprises a duct body and a tension disc, the duct body comprises a bottom surface and two side surfaces connected with the bottom surface, the bottom surface and the side surfaces are arranged in the length direction of the carriage, and the bottom surface and the side surfaces jointly define anaccommodating cavity; the tension disc is fixedly arranged in the accommodating cavity, a gap is formed between the tension disc and the bottom face, a plurality of wire harness fixing grooves are formed in the side, facing the bottom face, of the tension disc, and the wire harness fixing grooves are arranged in parallel. According to the wire duct provided by the embodiment of the invention, theplurality of wire harnesses of the cable can be respectively placed in the plurality of wire harness fixing grooves, so that the plurality of wire harnesses are arranged side by side, the current-carrying capacity of the cable is favorably increased, and the driving safety is improved.

Description

technical field [0001] The present application relates to rail vehicle manufacturing technology, in particular to a trunking, a carriage and a rail vehicle. Background technique [0002] At present, rail vehicles are mostly electrified vehicles pulled by electric locomotives, and the electric locomotive or generator car is centrally powered, and each carriage is electrically connected to the electric locomotive or generator car through cables to obtain electric energy. Therefore, wire grooves extending along the length direction of the carriages are all provided in each carriage, and cables are arranged in the wire grooves to fix and protect the cables. [0003] Because the cables are long, the cables need to be fixed at certain distances in the trunking. In the solution of the related art, there is a tie rod for fixing the cables in the trunking, and the cables are wound by fasteners. On the tie bar to complete the fixation. [0004] However, since the cable includes mult...
