Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and specifically to a wiring harness arrangement structure in a cable trench. Background Technology

[0002] Cable trenches are essential infrastructure in power systems. Their primary function is to provide a standardized passage for cables, ensuring their neat and orderly arrangement and protecting them from external mechanical damage such as vehicle crushing, human sabotage, and natural disasters. Supports hold the cables up, maintaining a distance between them and the trench bottom to prevent direct contact with soil and water. Traditional supports are mostly fixed to one side of the trench during use. They only provide support for the cables and cannot classify and secure cables of different sizes. This results in a chaotic distribution of cables within the trench, requiring maintenance personnel to spend considerable time identifying and separating cables, thus reducing maintenance efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a structure for organizing wire harnesses in cable trenches, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cable harness arrangement structure in a cable trench, comprising an assembly frame, wherein a cable harness rack is fixedly mounted on the side wall of the assembly frame; The cable tie includes a fixing tube, with a U-shaped frame fixedly connected to the end of the fixing tube. A first limiting frame and a second limiting frame are evenly fixedly connected to the top and bottom of the fixing tube, respectively. Fixing frames are fixedly connected to the front and rear side walls of the fixing tube.

[0005] Preferably, the assembly frame includes a base, an assembly part is detachably and fixedly mounted on the top of the base, an assembly block is fixedly connected to the side wall of the assembly part, a bolt fixing hole is provided at the center of the assembly block, and assembly holes are evenly provided on the front and rear side walls of the assembly part.

[0006] Preferably, the assembly rack is L-shaped.

[0007] Preferably, the inner sidewall of the U-shaped frame is integrally formed with a limiting block, and the sidewall of the assembly part is uniformly provided with limiting slots.

[0008] Preferably, the first limiting frame and the second limiting frame are respectively provided with assembly slots, and rollers are rotatably connected in the assembly slots.

[0009] Preferably, the fixing frame is provided with a first fixing area and a second fixing area.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: A cable harness organization structure within a cable trench employs a combination of an assembly frame and a cable bundler. The assembly frame features an L-shaped design, which improves stability when fixed within the cable trench. The cable bundler can be configured with the appropriate assembly height based on construction requirements. Furthermore, a first or second limiting frame can be selected to organize the cables according to their dimensions. The arc-shaped grooves and rotatably connected rollers within the first and second limiting frames facilitate smoother cable movement within the limiting frames, reducing friction between the cables and the limiting frames and protecting the cable sheath. The limiting blocks on the inner wall of the U-shaped frame cooperate with the limiting slots on the side wall of the assembly section, enabling rapid positioning and fixation of the cable bundler on the assembly frame, thus improving installation efficiency.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1 to 8 This utility model provides a technical solution: a cable harness arrangement structure in a cable trench, including an assembly frame 1 and a cable bundle frame 2. The assembly frame 1 is uniformly fixedly assembled in the side wall of the cable trench. The cable bundle frame 2 can be fixedly assembled at different height positions of the assembly frame 1 according to construction requirements. Through the cable bundle frame 2, cables with different cross-sectional sizes in the cable trench can be bundled and arranged, making the distribution of cables in the cable trench neater and facilitating subsequent maintenance and repair.

[0022] like Figure 2 As shown, the assembly frame 1 includes a base 11, which is fixedly connected to the bottom ground of the cable trench by fixing bolts. An assembly part 12 is detachably fixed to the top of the base 11 by fixing bolts. An assembly block 13 is welded and fixed to the side wall of the assembly part 12. A bolt fixing hole 14 is opened in the middle of the assembly block 13. By screwing the fixing bolt into the wall of the cable trench through the bolt fixing hole 14, the assembly part 12 can be connected and fixed to the inner wall of the cable trench. The height of the base 11 is fixed, while the height of the assembly part 12 can be set according to the height of the cable trench. After the assembly part 12 and the base 11 are assembled and fixed, an L-shaped structure is formed. The base 11 can increase the stability of the assembly part 12 in the cable trench. Assembly holes 15 are evenly opened on the front and rear side walls of the assembly part 12. The cable tie 2 can be fixedly assembled to the side wall of the assembly part 12 by the cooperation of fixing bolts and fixing nuts. During construction, the cable tie 2 can be fixedly assembled at different height positions on the side wall of the assembly part 12 according to the construction needs.

[0023] like Figure 3 As shown, the cable tie 2 has an integrally formed limiting block 3, and the side wall of the assembly part 12 has evenly spaced limiting slots 4. The dimensions of the limiting block 3 and the limiting slots 4 are matched. First, by setting the limiting block 3 and the limiting slots 4, the assembly convenience between the cable tie 2 and the assembly part 12 can be improved. After the limiting block 3 is engaged with the corresponding position in the limiting slot 4, the bolt holes in the cable tie 2 correspond to the assembly holes 15 on the side wall of the assembly part 12, which facilitates the fixing bolts to pass through the cable tie 2 and the assembly part 12, thereby improving the assembly efficiency of the cable tie 2. At the same time, after the cable tie 2 is fixed with fixing bolts and fixing nuts, the engagement of the limiting block 3 and the limiting slots 4 can enhance the stability of the cable tie 2 during use, preventing it from deforming or falling off the side wall of the assembly part 12 during cable support, thus avoiding unstable cable bundle arrangement.

[0024] like Figure 3 and Figure 4As shown, the cable tie 2 includes a fixing tube 21, and a U-shaped frame 22 is welded and fixed to the side wall of the fixing tube 21. The U-shaped frame 22 is used to connect and fix with the assembly part 12. The limiting block 3 is integrally formed on the inner side wall of the U-shaped frame 22. The fixing tube 21 is a square tube, and a first limiting frame 23 and a second limiting frame 24 are evenly welded and fixed to the top and bottom of the fixing tube 21, respectively. The first limiting frame 23 and the second limiting frame 24 are respectively provided with arc-shaped grooves for the passage of cables. The number of first limiting frames 23 and the number of second limiting frames 24 are different, and they are used to limit cables of different sizes. The first limiting frame 23 is mainly used for cables with a cross-section of 120-150mm. 2 The second limiting bracket 24 is mainly used for cable bundling and tidying of cables with a cross-section of 50-70mm². 2 The cables are bundled and organized. There are at least two first limiting frames 23 and at least three second limiting frames 24. Fixing frames 25 are evenly welded and fixed on the front and rear side walls of the fixing tube 21. The fixing frames 25 are used for binding with cable ties and can assist the first limiting frames 23 and the second limiting frames 24 in bundling and organizing the cables.

[0025] like Figure 5 As shown, the fixing frame 25 is provided with a first fixing area 251 and a second fixing area 252. The first fixing area 251 and the second fixing area 252 are respectively used to cooperate with the first limiting frame 23 and the second limiting frame 24. The cables at their corresponding positions can be bundled and sorted. The binding straps used with the first limiting frame 23 and the second limiting frame 24 can be classified, which can improve the neatness of the cable bundle and facilitate later maintenance and repair.

[0026] like Figure 4 As shown, the first limiting frame 23 and the second limiting frame 24 are respectively provided with assembly slots 26 that are symmetrically distributed on the left and right. Rollers 27 are rotatably connected in the assembly slots 26. The curvature of the rollers 27 corresponds to the curvature of the arc-shaped slots. By setting the rollers 27, the cable can pass through the arc-shaped slots more smoothly during the construction and laying process.

[0027] Working principle: such as Figure 6 , Figure 7 and Figure 8 As shown, the different usage states of this utility model in the process of cable bundling and arrangement will now be described. When the cross-sectional dimension of the cable to be arranged in the cable trench is large, the first limiting frame 23 can be fixedly connected to the assembly part 12 with the first limiting frame 23 facing upward. Figure 6As shown, after the cable passes through the arc-shaped groove in the first limiting frame 23, it can be pre-fixed by passing the cable tie through the first fixing area 251 in the fixing frame 25. At this time, as needed for assembly, the cable can be dragged in the first limiting frame 23 in the forward and backward directions. Since the roller 27 is provided, the movement of the cable in the first limiting frame 23 can be smoother. After the cable is assembled to the designated installation area, tighten the cable tie again to fix the cable in the first limiting frame 23 for cable bundling.

[0028] Similarly, when the cross-sectional size of the cable to be arranged is small, the second limiting bracket 24 can be fixedly connected to the assembly part 12 in an upward direction. Figure 7 In the indicated state, the cables are bundled and organized using the second limiting bracket 24. If it is necessary to organize both cables with large and small cross-sectional dimensions, the first limiting bracket 23 needs to be fixedly connected to the assembly part 12 in an upward direction. Figure 8 As shown in the diagram. Since cables with smaller cross-sectional dimensions are relatively lighter than those with larger cross-sectional dimensions, they are tied within the second limiting frame 24 using straps for suspension. This reduces the stress on the straps and improves the stability of the cable bundle arrangement. When in... Figure 8 In the indicated state, the cable ties can be passed through the first fixing area 251 and the second fixing area 252 respectively. At this time, the first fixing area 251 and the second fixing area 252 can provide a stable fixing effect according to the characteristics of cables of different sizes. For cables with larger cross-sectional dimensions, the cable tie passing through the first fixing area 251 can provide sufficient tension to ensure that its position is stable within the first limiting frame 23; while for cables with smaller cross-sectional dimensions, the cable tie passing through the second fixing area 252 can bind them well within the second limiting frame 24 with relatively light tension, making the cable layout in the entire assembly area more orderly, which not only facilitates subsequent maintenance and management, but also effectively avoids mutual interference between cables.
