The bottom of the main cable tray 100 is provided with a first outlet 1021 for high-voltage cable outlet. The auxiliary cable tray 200 is disposed on the side of the main cable tray 100, and a second outlet 201 for high-voltage cable outlet is also provided along the width direction of the auxiliary cable tray 200.

[0032] The high-voltage cable tray structure for urban rail vehicles disclosed in this embodiment allows for vertical routing of high-voltage cables through a first outlet 1021 to meet the routing requirements of block-shaped equipment, and horizontal routing of high-voltage cables through a second outlet 201 to meet the routing requirements of long, parallel-shaped equipment. Compared with the prior art, the high-voltage cable tray structure for urban rail vehicles disclosed in this embodiment can achieve reasonable routing of high-voltage cables within a limited space, avoiding the cross-stacking of high-voltage cables, thereby meeting the interface requirements of various equipment under the vehicle.

[0033] It should be explained that the "longitudinal" direction of the high-voltage cable trough in rail vehicles refers to the direction along the track, the "lateral" direction refers to the direction that is horizontal and perpendicular to the track, and the "vertical" direction refers to the direction that is vertical and perpendicular to the track surface.

[0034] It should be noted that the high-voltage cable tray structure of the urban rail vehicle disclosed in this utility model embodiment also includes a transition cable tray 300, an external high-voltage cable tray 400, and an internal high-voltage cable tray 500. The transition cable tray 300 is used to realize a smooth transition connection between different areas and different routes of the line. There is a cable passage hole between the external high-voltage cable tray 400 and the internal high-voltage cable tray 500, and the cable passage hole realizes the complete wiring method of the high-voltage cable under the vehicle.

[0035] This utility model embodiment does not limit the specific structure of the main cable trough 100. Any structure that meets the usage requirements of this utility model is within the protection scope of this utility model.

[0036] As one embodiment, please refer to Figures 2-4 The main cable tray 100 disclosed in this embodiment of the present invention includes a cable tray body 101, a bottom cover plate 102, a side frame and a transverse frame 105. The bottom cover plate 102 is connected to the cable tray body 101, and the side frame and the transverse frame 105 are both disposed on the bottom cover plate 102.

[0037] Specifically, the side frame includes a first side frame 103 and a second side frame 104, both of which are respectively disposed on both sides of the bottom cover plate 102 along the length direction of the bottom cover plate 102.

[0038] The transverse frame 105 comprises multiple components, arranged transversely on the bottom cover plate 102, with any two adjacent transverse frames 105 having the same or different distances between them. This arrangement enhances the overall strength and rigidity of the high-voltage cable tray.

[0039] The transverse frame 105 also has multiple binding holes for wire rolling.

[0040] As a further embodiment, the high-voltage cable tray structure for urban rail vehicles disclosed in this utility model embodiment is further provided with a partition plate 106 along the length of the bottom cover plate 102 to divide the main cable tray 100 into at least two partition cavities. This arrangement can isolate different types of electromagnetic interference.

[0041] The partition plate 106 can be set one or more, that is, the main cable groove 100 can be divided into two partition cavities or more than three partition cavities by the partition plate 106.

[0042] Of course, the lengths of different partition plates 106 can be the same or different, and the sizes of the partition cavities formed can be the same or different.

[0043] As a further embodiment, please refer to Figure 3 The main cable trough 100 disclosed in this embodiment of the present invention also includes reinforcing ribs 107. There are multiple reinforcing ribs 107, which are arranged laterally on the bottom cover plate 102.

The fastening component is disposed at the lower part of the transverse frame 105 so that the transverse frame 105 can cover the fastening component.

[0045] As a further embodiment, please refer to Figure 4 The fastening assembly disclosed in this embodiment of the utility model includes a bolt 108 and a nut 109. The main body of the bolt 108 passes through the main body 101 of the wire trough and the bottom cover plate 102. The threaded head of the bolt 108 is recessed within the transverse frame 105. The nut 109 is tightened onto the bolt 108. This arrangement not only ensures a smooth interior without sharp corners or edges in the wire trough but also facilitates tightening and loosening of the bolt 108 from the outside.

[0046] As a further embodiment, the fastening assembly disclosed in this utility model embodiment also includes an anti-loosening washer 110 disposed between the nut 109 and the bottom cover plate 102. The anti-loosening washer 110, through its special structure and performance, can provide additional friction or mechanical locking force after the bolt 108 and nut 109 are tightened, effectively resisting external forces that could loosen the bolt 108 and ensuring the reliability of the connection.
