Description

Technical Field

[0001] This utility model relates to the field of cable tray bridging technology, and in particular to a cable tray bridging structure with adjustable length and angle. Background Technology

[0002] Currently, subway construction has entered a phase of rapid construction, with construction periods constantly shortening. The phenomenon of overlapping and parallel construction will continue, especially with immense pressure on post-station construction, where we essentially have zero construction time. Research on a cable tray tower bend with adjustable length and angle can not only shorten construction time and standardize installation quality and connection processes, but also improve aesthetics and increase efficiency in cable tray bridging installation while reducing manpower input.

[0003] Existing technologies have significant shortcomings in the length and angle adjustment of cable tray bridging joints. The main issue is that the range of expansion and contraction and the rotation angle of the connection are structurally limited, making it difficult to flexibly adapt to the needs of different installation scenarios. Traditional cable tray bridging components typically use fixed-size designs, only compatible with cable trays at specific spacings. When encountering non-standard spans or irregular corners, on-site cutting or custom processing is often required, significantly reducing construction efficiency. Furthermore, conventional connection methods such as bolting or welding require repeated disassembly and reassembly during adjustment, which is not only cumbersome but also prone to reducing connection strength, affecting long-term stability. This makes it difficult to achieve rapid installation and precise connection of the cable tray system, increasing project time and labor costs.

[0004] To address the aforementioned problems, this utility model proposes a cable tray bridging structure with adjustable length and angle. Utility Model Content

[0010] This invention is further configured such that the first bent section groove is slidably sleeved on the outside of the second bent section groove, and the fan-shaped connecting piece is disposed on the outside of the straight section groove, the first bent section groove, and the second bent section groove. During operation, the first bent section groove needs to be smoothly slid along the outside of the second bent section groove. After confirming the predetermined angle has been reached by visual inspection or an angle measuring tool, matching bolts are used to pre-fix the groove by passing them sequentially through the corresponding holes of the first sliding groove and the first limiting groove. Then, the first sliding groove and the first limiting groove are pre-connected in the same manner.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Please see Figure 1-3 This utility model provides a technical solution: a cable tray bridging structure with adjustable length and angle, including a straight section groove 1, a first bent section groove 2, a fan-shaped connecting piece 3, and a second bent section groove 4. The straight section groove 1, the first bent section groove 2, and the second bent section groove 4 are all U-shaped structures. A second limiting groove 11 is provided on both sides of the straight section groove 1. A first limiting groove 7 and a second arc-shaped connecting groove 8 are respectively provided on both sides of the first bent section groove 2 and the second bent section groove 4. A first arc-shaped connecting groove 5 is provided on the fan-shaped connecting piece 3. The first bent section groove 2 and the second bent section groove 4 are both bolted to the straight section groove 1 via the fan-shaped connecting piece 3. A first sliding groove 6 is provided on the side wall of the first bent section groove 2 above the first limiting groove 7, and a second sliding groove 9 is provided on the side wall of the second bent section groove 4 below the first limiting groove 7. The first bending section groove 2 and the second bending section groove 4 are connected by bolts to the first sliding groove 6 and the second sliding groove 9.

[0022] The first arc-shaped connecting groove 5, the first limiting groove 7, the second arc-shaped connecting groove 8, and the second limiting groove 11 are all in two layers, with each layer corresponding to the first arc-shaped connecting groove 5, the first limiting groove 7, the second arc-shaped connecting groove 8, and the second limiting groove 11.

[0023] The top of the straight section groove 1, the first bent section groove 2, and the second bent section groove 4 are all fitted with cover plates 10.

[0024] The bottom sides of the bend connection between the first bending section groove 2 and the straight section groove 1, as well as the bottom sides of the bend connection between the second bending section groove 4 and the straight section groove 1, are all fixed by steel hinges. The steel hinges provide high-strength bending support, ensuring long-term durability at the corners.

[0025] The first bending segment groove 2 is slidably sleeved on the outside of the second bending segment groove 4. The sliding sleeve structure allows the two grooves to be extended and adjusted to adapt to different bridging length requirements. The fan-shaped connecting piece 3 is set on the outside of the straight segment groove 1, the first bending segment groove 2, and the second bending segment groove 4.

[0026] Working principle:

[0027] Based on the required bridging angle for actual installation, first precisely adjust the relative positions of the first bending section groove 2 and the second bending section groove 4. During operation, the first bending section groove 2 should be smoothly slid along the outer side of the second bending section groove 4. After confirming that the predetermined angle has been reached by visual inspection or angle measuring tools, use the matching bolts to pre-fix the grooves 6 and 7 by passing them through the corresponding holes in the first sliding groove 6 and the first limiting groove 7 in sequence. Then, pre-connect the second sliding groove 9 and the first limiting groove 7 in the same way.

[0028] Subsequently, the fan-shaped connecting piece 3 is precisely aligned with the second limiting groove 11 of the straight section groove 1, while its first arc-shaped connecting groove 5 is completely matched with the second arc-shaped connecting groove 8 of the first bent section groove 2 and the second bent section groove 4 respectively. M6 stainless steel bolts are used with anti-loosening washers for three-point fastening.

[0029] Finally, the pre-assembled cover plate 10 is smoothly pushed in along the snap-fit ​​track to complete the installation of the entire bridging structure. The entire adjustment process can be completed with just a regular wrench, without the need for special tools. A single person can complete both angle and length adjustments within 3 minutes. The ±5mm displacement caused by thermal expansion and contraction is automatically compensated by the sliding groove structure, avoiding structural stress.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
