Description

Technical Field

[0001] This utility model belongs to the field of rail vehicle technology, and specifically relates to a rail vehicle onboard cable tray installation device. Background Technology

[0002] In the field of urban rail transit, the internal structural design and assembly process of urban rail vehicles have a crucial impact on many aspects, including overall vehicle performance, passenger experience, and assembly efficiency. Among these, the track gauge of urban rail vehicles, as an important internal component, plays a multifaceted role in vehicle assembly.

[0003] The existing cable trays on urban rail vehicles are usually made of multiple aluminum alloy profiles. The top of the cable tray is installed on the vehicle body, and the internal cavity is used for cable routing. While realizing the cable routing function, the lower groove is used to install components such as the middle and side roof panels of the vehicle, and it also serves as a secondary frame for the roof, supporting the stability and integrity of the vehicle's internal structure.

[0004] However, existing on-vehicle wiring harness installation technology has some prominent problems. Firstly, the installation accuracy requirements for on-vehicle wiring harnesses are extremely high, especially the installation height and the alignment dimensions of the wiring harnesses on both sides with the longitudinal centerline of the vehicle body. This places strict demands on ensuring the aesthetic appearance of the vehicle's interior. However, in practice, workers typically use a measuring tape to manually measure the installation height of the on-vehicle wiring harnesses, a method with significant errors.

[0005] Furthermore, the distance between the cable trays on the vehicle and the longitudinal center of the car body is difficult to measure directly; it can only be determined indirectly by measuring the distance to the adjacent air ducts. This method easily leads to tolerance accumulation, which in turn affects the installation effect of interior components, requiring frequent rework and adjustments during assembly. This severely reduces the efficiency of vehicle assembly, increases production and time costs, and hinders the urban rail vehicle manufacturing industry from moving towards higher efficiency and higher quality development.

[0006] Therefore, there is an urgent need to develop an installation tool that can improve the installation accuracy of the cable trays on the vehicle, reduce measurement errors, and avoid tolerance accumulation, so as to meet the high-precision requirements of urban rail transit vehicle assembly and improve assembly efficiency and quality.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] The core of this utility model is to provide a track vehicle onboard cable tray installation device, which realizes high-efficiency and high-precision installation of the onboard cable tray.

[0041] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] For details, please refer to Figures 1-8 The present invention provides a track vehicle onboard cable tray installation device, comprising: at least two brackets forming a 100 and at least one positioning crossbeam forming a 200.

[0043] The bracket assembly 100 provides support for the track trough 300 and positions the track trough 300 in the height direction. Typically, track troughs 300 are installed on both sides of the track vehicle along its width. Therefore, the number of bracket assemblies 100 is at least two. When the number of bracket assemblies 100 is three or more, multiple bracket assemblies 100 can be distributed below the track troughs 300 on both sides of the track vehicle.

[0044] Specifically, each bracket assembly 100 includes a base 110, a connecting support rod 120, a top crossbeam 130, a first top support rod 141, and a second top support rod 142. The connecting support rod 120 is vertically arranged and its two ends are connected to the base 110 and the top crossbeam 130, respectively. The top crossbeam 130 is horizontally arranged and its two ends are respectively provided with the first top support rod 141 and the second top support rod 142. The first top support rod 141 and the second top support rod 142 of each bracket assembly 100 are used to support the bottom of the on-board wiring trough 300 on the same side. Since the first top support rod 141 and the second top support rod 142 are arranged at intervals on the upper surface of the top crossbeam 130, two-point support is achieved at the bottom of the on-board wiring trough 300.

[0045] The positioning crossbeam 200 is used to position the on-board cable trays 300 on both sides of the rail vehicle in the width direction.

[0046] Specifically, the positioning beam assembly 200 includes a horizontal support beam 210, a positioning block 220, and two first right-angle connectors 230. A first right-angle connector 230 is provided at each end of the horizontal support beam 210. The right-angle sides of the two first right-angle connectors 230 of the positioning beam assembly 200 are respectively used to fit against the inner surface of the corresponding side of the on-board groove 300. The positioning block 220 is located at the center of the horizontal support beam 210, and the positioning block 220 is marked with a centerline or center groove for centering. The center groove can be a centerline notch provided on the positioning block 220, and can be produced using aluminum sheet machining.

[0047] The specific alignment method can be to use a laser ink line instrument to mark the longitudinal center line of the vehicle body inside the rail vehicle, and ensure that the center position line on the positioning block 220 coincides with the longitudinal center line of the vehicle body marked by the laser ink line instrument, thereby achieving alignment of the on-board grooves 300 set on both sides.

[0048] This utility model provides a track vehicle onboard cable tray installation device. In actual operation, the onboard cable tray 300 is first hoisted onto the roof of the track vehicle. A support assembly 100 is placed from the longitudinal center of the vehicle body towards the side wall, providing initial support for the bottom of the onboard cable tray 300. Then, a positioning beam assembly 200 is placed from bottom to top, ensuring that the center line or center groove of the positioning block 220 on the positioning beam assembly 200 coincides with the longitudinal center line of the vehicle body projected by a laser line instrument. Simultaneously, the position of the onboard cable tray 300 is adjusted to ensure that the edge of the onboard cable tray 300 near the longitudinal center line of the vehicle body is in contact with the right-angle side of the first right-angle connector 230 of the positioning beam assembly 200, and that the lower part of the onboard cable tray 300 is completely in contact with the support assembly 100. Finally, the onboard cable tray 300 is fixed to the roof of the vehicle, thus completing the installation of the onboard cable tray 300. The above-mentioned track vehicle onboard cable tray installation device, with the bracket assembly 100 and the positioning crossbeam assembly 200 used together, and aligned with the device that can display the longitudinal centerline of the vehicle body, can achieve high-efficiency and high-precision installation of the onboard cable tray 300.

[0049] To improve the support stability of the base 110, the base 110 includes a first bottom crossbeam 111 and a second bottom crossbeam 112. The first bottom crossbeam 111 and the second bottom crossbeam 112 are arranged perpendicularly in a cross shape, which has good structural stability.

[0050] Furthermore, this solution also includes a second right-angle connector 113, which connects the first bottom crossbeam 111, the second bottom crossbeam 112, and the connecting support rod 120.

[0051] This solution also includes a third right-angle connector 160, and the first top support rod 141 and the second top support rod 142 are respectively connected to the top crossbeam 130 through the third right-angle connector 160.

[0052] like Figure 7 As shown, the first right-angle connector 230, the second right-angle connector 113, and the third right-angle connector 160 are all right-angled triangles. The right-angled sides of these right-angle connectors are used for close-fitting connection with the crossbeam and support rod.

[0053] To improve structural strength, such as Figure 5 As shown, the first right-angle connector 230 and the positioning beam assembly 200 are connected by a first fastener 240. Figure 3 As shown, the second right-angle connector 113 is connected to the first bottom crossbeam 111, the second bottom crossbeam 112 or the connecting support rod 120, and / or the third right-angle connector 160 is connected to the first top support rod 141, the second top support rod 142 or the top crossbeam 130 by the second fastener 170.

[0054] In a specific embodiment, the fastener includes a screw 410, a nut 440, and a spring washer 420 and a flat washer 430 disposed between the screw 410 and the nut 440, as detailed below. Figure 7 and Figure 8 Screw 410 can be an internal hex socket head cap screw.

[0055] To achieve stable support, such as Figure 6 As shown, each vehicle wiring trough 300 is provided with two brackets forming a 100, and the two brackets forming the 100 are spaced apart along the length of one vehicle wiring trough 300.

[0056] In a specific embodiment, a nylon pad is provided on the contact surface between the first right-angle connector 230 of the bracket assembly 100 and the positioning crossbeam assembly 200 and the vehicle wiring trough 300, which can prevent damage to the surface paint of the vehicle wiring trough 300 during installation. Figure 3 As shown, a first nylon pad 150 is provided at the top of both the first top support rod 141 and the second top support rod 142. Figure 5 As shown, a second nylon pad 250 is provided on the right-angle side of the first right-angle connector 230 and on the upper surface of the horizontal support beam 210 facing the side of the vehicle wiring trough 300. The second nylon pad 250 is L-shaped in general and can be pasted onto the horizontal support beam 210 and the first right-angle connector 230 according to the size.

[0057] When installing the wiring trough 300, it is necessary to ensure that the wiring trough 300 is in close contact with the first nylon pad 150 on the first top support rod 141 and the second top support rod 142.

[0058] Specifically, when the center line or center groove of the positioning block 220 coincides with the longitudinal center line of the vehicle body, the edge of the upper wire groove 300 near the longitudinal center line of the vehicle body is in contact with the first right-angle connector 230, and the lower part of the upper wire groove 300 is completely in contact with the bracket assembly 100, after inserting an adjusting shim between the upper wire groove 300 and the vehicle body / roof sliding groove, tighten the upper wire groove installation fasteners to fix the upper wire groove 300 to the roof, thus completing the installation of the upper wire groove 300.

[0059] This utility model achieves high-efficiency and high-precision installation of the 300mm on-board cable tray by using a set of tooling for supporting and limiting the installation of the cable tray on the rail vehicle. No dimensional measurement is required during installation, avoiding the tolerance accumulation problems associated with manual measurement and installation. This allows for a one-time installation, improving efficiency. Furthermore, it ensures the smooth installation of subsequent components such as the center and side roof panels inside the vehicle.

[0060] When the bottom installation height of each wire groove 300 on the side closer to the longitudinal center line of the vehicle body is higher than the bottom installation height on the side farther from the longitudinal center line of the vehicle body, the height of the second top support rod 142 used to support the wire groove 300 on the side closer to the longitudinal center line of the vehicle body is higher than the height of the first top support rod 141 used to support the wire groove 300 on the side farther from the longitudinal center line of the vehicle body.

[0061] In a specific embodiment, the contact surfaces of the first top support rod 141 and the second top support rod 142 with the vehicle wiring trough 300 are L-shaped connection surfaces, that is, notches are formed at the top of the first top support rod 141 and the second top support rod 142, which can play the role of support and height positioning. The design size of the notch can ensure the installation height and installation angle of the vehicle wiring trough 300.

[0062] The profiles used in the track vehicle cable tray installation device are all industrially common aluminum profiles with sliding grooves and right-angle connectors, which are cut and produced according to size. They have the characteristics of simple structure, low investment and good economy.
