Description

Technical Field

[0001] This utility model relates to cable supports, specifically a cable trench pre-embedded channel support. Background Technology

[0002] In the field of power transmission, cable trenches, as a critical infrastructure for cable laying, rely heavily on the performance of their internal supports. Traditional cable trench pre-buried channel supports suffer from numerous structural instability issues. Firstly, past supports often employed simple fixing methods, lacking effective restraint structures, making them highly susceptible to external interference during long-term use. For instance, in open areas or areas with weak security, thieves often attempt to quickly dismantle supports to steal cables when no one is looking. Because traditional supports lack specific anti-tamper designs, they quickly loosen in such situations, causing the cables to lose support and potentially leading to mutual pulling and friction between cables, damaging the cable sheath. This severely threatens the continuity of power transmission, frequently causing power outages and significant inconvenience to production and daily life.

[0003] Therefore, there is an urgent need in the market for a better cable trench pre-embedded channel support. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a cable trench pre-embedded channel support.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a cable trench pre-embedded channel support: including a vertical support, wherein the vertical support is vertically arranged;

[0006] A support mechanism is fixedly provided on the inner side of the vertical bracket;

[0007] The support mechanism includes a vertical tube body, which is fixedly installed inside a vertical bracket, and an auxiliary plate is provided on the upper inner side of the vertical tube body;

[0008] The support mechanism also includes an insertion tube, an extension plate is provided on the upper inner side of the insertion tube, a nut is fixedly provided on the extension plate, a wing bolt is provided on the nut, and a cable bracket is fixedly provided on the upper front side of the insertion tube.

[0009] The insertion tube is inserted into the vertical tube, the extension plate is attached to the auxiliary plate, and the stud of the wing bolt passes through the extension plate and the auxiliary plate, thereby restricting the insertion tube from extending out of the vertical tube.

[0010] As an improvement, the projection of the vertical support in the top view direction presents a U-shape.

[0011] As an improvement, the vertical back portion of the vertical bracket is provided with fixing holes.

[0012] As an improvement, the number of fixing holes is several and they are evenly distributed from the upper part of the vertical back portion to the lower part of the vertical back portion.

[0013] As an improvement, the front part of the vertical tube body protrudes forward to form a front support part;

[0014] The lower side of the cable bracket is supported by the front support.

[0015] As an improvement, the vertical tube body has a square projection when viewed from above, and the upper and lower ends of the vertical tube body are transparent.

[0016] As an improvement, the projection of the insertion tube in the top view is square, and the upper and lower ends of the insertion tube are transparent.

[0017] As an improvement, the cable bracket is provided with a support pad, the support pad being made of rubber;

[0018] The upper part of the cable bracket is horizontally positioned.

[0019] As an improvement, the extension plate and the nut are fixedly connected by welding.

[0020] The advantages of this invention compared to existing technologies are as follows: Stability Guarantee: Through a unique structural design, the stability of the entire support structure is greatly improved. Specifically, the stud portion of the wing bolt passes sequentially through the extension plate and the auxiliary plate, effectively limiting the insertion of the tube and preventing it from easily extending outward from the vertical tube. Even in the event of unforeseen circumstances such as a thief attempting to quickly disassemble and steal the cable, it reliably ensures the cable is safely and stably supported within the cable trench, greatly reducing the risk of cable failures caused by loose or damaged supports, and providing a solid guarantee for the continuity of power transmission.

[0021] Convenient and efficient installation features: During installation, the seamless coordination between components greatly enhances ease of installation. For example, the insert tube, with its square top-down projection and open top and bottom, allows for precise positioning by the extension plate on the upper side of the insert tube precisely fitting with the auxiliary plate of the vertical tube, reducing adjustment and calibration time during installation. Furthermore, the pre-welded nuts and matching wing bolts on the extension plate further simplify the installation process, making the entire bracket installation efficient and smooth, effectively saving labor and time costs.

[0022] Excellent cable protection: The support pads on the cable brackets are made of rubber, a unique design feature. Firstly, the softness of rubber effectively cushions the impact of vibration and shaking during daily operation, preventing damage to the cable's outer sheath from long-term friction and collisions, thus extending the cable's lifespan. Secondly, the upper part of the cable bracket is intentionally kept horizontal, providing a stable surface for the cable and ensuring its stability after installation. This further reduces the adverse effects on power transmission caused by cable displacement and twisting, providing comprehensive protection for the cable's safe operation.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Referring to the accompanying drawings, a cable trench pre-embedded channel support includes a vertical support 1, which is vertically arranged. The projection of the vertical support 1 in the top view is U-shaped. The vertical back portion 2 of the vertical support 1 is provided with fixing holes 3. The number of fixing holes 3 is several and they are evenly distributed from the upper part to the lower part of the vertical back portion 2. It is fixed to the side wall of the cable trench by bolts or other devices.

[0034] The vertical support 1 is fixedly provided with a support mechanism 4. The support mechanism 4 includes a vertical tube 5. The vertical tube 5 is square in shape when viewed from above. The upper and lower ends of the vertical tube 5 are open. The vertical tube 5 is fixedly installed inside the vertical support 1. An auxiliary plate 6 is provided on the upper part of the inner side of the vertical tube 5. The front part of the vertical tube 5 protrudes forward to form a front support part 7.

[0035] The support mechanism 4 also includes an insertion tube 8, which has a square projection when viewed from above. The upper and lower ends of the insertion tube 8 are open. An extension plate 9 is provided on the upper inner side of the insertion tube 8, and a nut 10 is fixedly mounted on the extension plate 9. The extension plate 9 and the nut 10 are fixedly connected by welding. A wing bolt 11 is provided on the nut 10. A cable bracket 12 is fixedly mounted on the upper front side of the insertion tube 8, and a support pad 13 made of rubber is provided on the cable bracket 12. The upper part of the cable bracket 12 is horizontally positioned.

[0036] The insertion tube 8 is inserted into the vertical tube 5, the extension plate 9 is attached to the auxiliary plate 6, the lower side of the cable bracket 12 is supported by the front support 7, and the stud of the wing bolt 11 passes through the extension plate 9 and the auxiliary plate 6, which serves to restrict the insertion tube 8 from extending out of the vertical tube 5.

[0037] First, prepare all components, including the vertical bracket 1. Observe the vertical bracket 1; it is placed vertically and has a U-shaped appearance when viewed from above. Next, examine the vertical back portion 2 of the vertical bracket 1. On this portion, several fixing holes 3 are evenly distributed. These fixing holes 3 are arranged sequentially at certain intervals from the upper part of the vertical back portion 2 to the lower part of the vertical back portion 2.

[0038] Then, select appropriate bolts or other equivalent fixing devices, pass the bolts through the fixing holes 3, so that the vertical bracket 1 fits tightly against the side wall of the cable trench. By tightening the bolts, ensure that the vertical bracket 1 is firmly fixed to the side wall, providing a solid foundation for subsequent installation.

[0039] After fixing the vertical bracket 1, the support mechanism 4 is installed. The vertical tube 5 in the support mechanism 4 has a square top view and is open at both ends. The vertical tube 5 is precisely placed in the pre-set position inside the vertical bracket 1, and the two are fixed together by welding. Note that there is an auxiliary plate 6 on the upper inner side of the vertical tube 5, which is a key part for positioning subsequent components. Simultaneously, the front of the vertical tube 5 protrudes forward to form the front support part 7, which plays an important role in subsequent support.

[0040] Next, we will process the insertion tube 8, which is also square in top view and open at both ends. Carefully insert the insertion tube 8 into the vertical tube 5. During insertion, ensure that the extension plate 9 on the upper inner side of the insertion tube 8 accurately adheres to the auxiliary plate 6 of the vertical tube 5 for precise positioning. At this point, you can see that the nut 10 is firmly fixed to the extension plate 9 by welding, and the wing bolt 11 has been installed on the nut 10.

[0041] Next, examine the upper front part of the insertion tube 8. Here, a cable bracket 12 is fixed, with a rubber support pad 13 that cushions and protects the cable. The upper part of the cable bracket 12 remains horizontal to ensure stable cable placement. Finally, tighten the wing bolt 11 so that its stud portion passes through the extension plate 9 and the auxiliary plate 6 in sequence. This restricts the insertion tube 8 from extending outward from the vertical tube 5, greatly improving the stability of the entire structure. This effectively prevents the bracket from loosening or being damaged due to external factors, such as thieves attempting to quickly disassemble and steal it, ensuring the safe and stable support of the cable within the cable trench.

[0042] Stability Guarantee: The unique structural design significantly improves the stability of the entire support structure. Specifically, the stud portion of the wing bolt 11 passes through the extension plate 9 and the auxiliary plate 6 in sequence, effectively limiting the insertion tube 8 and preventing it from easily extending outward from the vertical tube 5. Even in the event of unexpected situations such as thieves attempting to quickly dismantle and steal the cable, it reliably ensures that the cable is safely and stably supported in the cable trench, greatly reducing the risk of cable failure caused by the support loosening or damage, and providing a solid guarantee for the continuity of power transmission.

[0043] Convenient and efficient installation features: During installation, the components work together seamlessly, greatly enhancing ease of installation. For example, the insert tube 8, with its square top-down projection and open top and bottom, allows for precise positioning by the extension plate 9 on the upper inner side of the insert tube 8 precisely fitting with the auxiliary plate 6 of the vertical tube 5 when inserted. This reduces the time required for debugging and calibration during installation. Furthermore, the pre-welded nuts 10 and matching wing bolts 11 on the extension plate 9 further simplify the installation process, making the entire bracket installation efficient and smooth, effectively saving manpower and time costs.

[0044] Excellent cable protection: The support pads 13 on the cable bracket 12 are made of rubber, a unique design feature. On one hand, the softness of rubber effectively cushions the impact of vibration and shaking during daily operation, preventing damage to the cable's outer sheath from long-term friction and collision, thus extending the cable's lifespan. On the other hand, the upper part of the cable bracket 12 is intentionally kept horizontal, providing a stable surface for the cable and ensuring it remains stable after installation. This further reduces the adverse effects on power transmission caused by cable displacement and twisting, providing comprehensive protection for the cable's safe operation.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
