Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a railway power supply cable tray. Background Technology

[0002] Currently, cable trays used in railway power supply systems have many shortcomings in practical applications. On the one hand, the width of traditional cable trays is mostly fixed, making it difficult to flexibly adjust according to the number and specifications of cables. When laying cables, improper width can easily lead to cable compression and wear, thus shortening the cable's service life. Furthermore, fixed-width cable trays occupy a large amount of space during storage, transportation, and handling, resulting in higher transportation costs. At the same time, their structural strength is difficult to guarantee under different width requirements, making them unable to well adapt to the complex cable laying needs of railway power supply systems.

[0003] On the other hand, existing cable tray connection mechanisms have limited angle adjustment during splicing, resulting in poor installation fit. This is especially problematic in complex terrains such as tunnels and bridges in railway power supply systems, making it difficult to meet cable laying requirements and easily creating installation dead angles. Furthermore, the inflexible splicing angle can lead to unreasonable cable routing, excessive cable bending causing insulation damage, and stress concentration at the splice points can easily cause structural damage, affecting the safety and reliability of the railway power supply system. Therefore, there is an urgent need to improve a railway power supply cable tray to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The width adjustment mechanism of this railway power supply cable tray allows for flexible adjustment of the tray width according to the number and specifications of cables, ensuring uniform cable laying and avoiding cable compression and wear caused by a fixed width, thus extending cable life. The folding design also reduces storage space, facilitating transportation and storage and lowering transportation costs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Based on existing technology, traditional cable trays typically have a fixed width, making it difficult to flexibly adjust according to the number and specifications of cables. During cable laying, unsuitable widths can easily lead to cable compression and wear, thus shortening cable lifespan. Furthermore, fixed-width trays occupy significant space during storage, transportation, and handling, resulting in higher transportation costs. Additionally, their structural strength is difficult to guarantee under varying width requirements, making them unsuitable for the complex cable laying needs of railway power supply systems. Therefore, this cable tray design incorporates a width adjustment mechanism that allows for flexible adjustment based on the number and specifications of cables. Please refer to [link / reference]. Figures 1-4 This utility model provides a technical solution: a railway power supply cable tray, including a cable tray 1, a protective cover 2 fixedly installed on the top of the cable tray 1 by bolts, the cable tray 1 is connected by splicing parts 3, and the surfaces of the cable tray 1 and the protective cover 2 are treated with arc spraying aluminum-based composite coating; the railway power supply cable tray includes a width adjustment mechanism and a connection mechanism, the width adjustment mechanism includes the cable tray 1 and the protective cover 2, the protective cover 2 is composed of cover body one 201 and cover body two 202, both cover body one 201 and cover body two 202 are "L" shaped designs, and the connection between the two cover bodies is provided with mutually staggered sliding grooves.

[0023] Multiple sets of limiting bolts 203 are fixedly installed on the cover body 1 201, and multiple sets of limiting grooves 204 are provided on the cover body 202. The limiting bolts 203 are located in the limiting grooves 204. Multiple sets of mounting holes 205 are provided on the sides of the cover body 1 201 and the cover body 202. Both the cover body 1 201 and the cover body 202 can be bent.

[0024] The cable tray 1 consists of a first side plate 301, a second side plate 302, and a bottom plate 303. The first side plate 301 and the second side plate 302, and the second side plate 302 and the bottom plate 303 are connected by hinges 304. The bottom of the first side plate 301, the second side plate 302, and the bottom plate 303 are all provided with mounting grooves 305 for mounting the hinges 304.

[0025] The base plate 303 is provided with multiple sets of through holes 307, and a rotating groove 308 is provided between the mounting grooves 305. A support clamp 310 is movably installed in the rotating groove 308 through a fixed shaft 309.

[0026] The rotating groove 308 is a circular groove, and three-quarters of the rotating groove 308 is located on the outer side plate centered on side plate 301. The fixed shaft 309 is located on side plate 301 and side plate 302 respectively.

[0027] The support clamp 310 is a semi-circular double-layer clamp. The support clamp 310 can rotate around the fixed shaft 309. The side plate 302 and the bottom plate 303 are provided with locking holes 312. The support clamp 310 is provided with a hole that matches it. When it is in the unfolded state, the locking hole 312 is provided with a locking bolt 311.

[0028] Loosen the limiting bolt 203, and cover body 1 201 and cover body 202 slide relative to each other along the slide groove. At the same time, side plate 1 301 and side plate 2 302 rotate through hinge 304, causing the base plate 303 to expand or contract. After adjusting to a suitable width, tighten the limiting bolt 203 to lock it into the limiting groove 204 and fix the protective cover. At the same time, unfold the support clamp 310 and insert the locking bolt 1 311 into the locking hole 1 312 to enhance the strength of the cable tray structure. After unfolding, rotate the support clamp to form a stable support with side plate 2 302 and base plate 303 to prevent structural deformation after width adjustment. Example

[0029] Based on Example 1, the angle adjustment is limited during the splicing and installation of cable trays, resulting in poor installation fit. This is especially problematic in complex terrains such as tunnels and bridges in railway power supply systems, making it difficult to meet cable laying requirements and easily creating installation dead angles. Furthermore, the inflexible splicing angle leads to unreasonable cable routing, excessive cable bending causing insulation damage, and stress concentration at the splice points can easily cause structural damage, affecting the safety and reliability of the railway power supply system. Therefore, this machine is equipped with an adjustable-angle connection mechanism. Please refer to [link / reference]. Figures 1-5 This utility model provides a technical solution: a railway power supply cable tray, the connecting mechanism of which includes a splicing component 3, which is composed of a first splicing plate 401 and a second splicing plate 402. The front end of the splicing plate is arc-shaped. The first splicing plate 401 and the second splicing plate 402 are rotatably connected by a rotating shaft 406. The splicing plate is provided with fixing holes 403, and the side of the cable tray 1 is fixedly installed by bolts. The front end of the first splicing plate 401 is provided with multiple sets of second locking holes 404 with the rotating shaft 406 as the center. The second locking holes 404 are provided with second locking bolts 405.

[0030] Splicing plate 1 401 and splicing plate 2 402 rotate around the pivot 406 to adapt to the angle requirements of terrains such as tunnels and bridges. After adjusting to the target angle, the splicing angle is fixed by inserting the locking bolt 2 405 into the corresponding locking hole 2 404 distributed around the pivot with the pivot as the center, thus preventing excessive bending of the cable routing.
