Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable protection technology, specifically to a cable protection device for power construction. Background Technology
[0002] During road construction, many electrical devices are often required, which typically need to be connected to a power source via long cables to operate. However, these cables frequently cross roads, and because they are exposed and lying in the middle of the road, construction vehicles and heavy machinery can easily run over them, causing damage and broken strands.
[0003] Existing methods for protecting cables crossing the road surface typically employ conduits or trapezoidal cable protection devices with internal cable routing channels. These cable protection plates are placed on the road surface to protect the cables. However, these existing cable protection plates or conduits are usually placed on construction sites. As construction vehicles continuously pass by, the cable protection device shifts forward, causing the cable to move along with it. Different vehicles will have different displacement distances, and if the displacement distance is large, the cable may be broken.
[0004] To address the aforementioned technical problems, this application proposes a cable protection device for power construction. Utility Model Content
[0005] I. Technical problems to be solved
[0006] The technical problem this invention aims to solve is that when the cable protection device moves, it also moves the cable simultaneously, which may break the cable if the displacement distance is large.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] As attached Figure 1 and attached Figure 4 As shown, a cable protection device for power construction includes a trapezoidal protection frame 1. The trapezoidal protection frame 1 has a hollow structure that extends to both ends. Multiple sets of support bends 7 are rotatably installed between the top and bottom of the trapezoidal protection frame 1. The ends of the support bends 7 are rotatably connected to the trapezoidal protection frame 1 through bearings, allowing the support bends 7 to rotate freely inside the trapezoidal protection frame 1. The height of the trapezoidal protection frame 1 is 3-8cm, facilitating the passage of various vehicles. The multiple sets of support bends 7 provide strong support for the top of the trapezoidal protection frame 1, preventing the trapezoidal protection frame 1 from collapsing and damaging the cable. The support bends 7 are horizontally placed "U"-shaped frames. There is a large space between the concave side of the "U"-shaped support bends 7 and the trapezoidal protection frame 1, providing ample space for cables to pass through the trapezoidal protection frame 1, allowing thicker cables or multiple sets of cables to pass through.
[0027] As attached Figure 1 Appendix Figure 3 and attached Figure 5As shown, the lower part of the two side walls of the trapezoidal protective frame 1 is provided with mounting guide grooves 2 respectively. One end of the mounting guide groove 2 extends through to one side of the trapezoidal protective frame 1. A protective plate 3 is rotatably installed on the inner side wall of the mounting guide groove 2. Multiple sets of locking blocks 4 are provided on the upper and lower side walls of the protective plate 3 respectively. The upper and lower side walls of the mounting guide groove 2 are provided with locking grooves 5 for the locking blocks 4 to be inserted. The surface of the locking block 4 is arc-shaped. The bottom of the locking groove 5 is in contact with the surface of the locking block 4. The locking block 4 is made of rubber and has a certain deformation capacity. When the protective plate 3 enters the interior of the mounting guide groove 2, the locking block 4 is squeezed and deformed, and is released in the locking groove 5 and locked in the locking groove 5. By locking the protective plate 3 in the locking groove 5 through multiple sets of locking blocks 4, the protective plate 3 is locked and limited inside the mounting guide groove 2. Since the material of the trapezoidal protective frame 1 is relatively hard and the supporting force of multiple sets of supporting bending frames 7 is strong, there is a gap between the protective plate 3 and the mounting guide groove 2. When a vehicle passes by, the protective plate 3 will not be squeezed out of the mounting guide groove 2.
[0028] The upper inner side of the mounting guide groove 2 is integrally formed with a limiting strip 6. The limiting strip 6 limits the inner side of the protective plate 3 to prevent the protective plate 3 from entering the trapezoidal protective frame 1 and to prevent the protective plate 3 from squeezing the cable.
[0029] When the trapezoidal protective frame 1 is pulled by the wheel, the cable moves inside the trapezoidal protective frame 1. The cable is pulled at a larger angle inside a group of trapezoidal protective frames 1 at the edge. The cable pushes the protective plate 3 to move outward. When the cable is subjected to a large pulling force, the locking block 4 moves out of the locking groove 5, causing the protective plate 3 to rotate out of the installation guide groove 2, and the cable to move out of the installation guide groove 2. This reduces the pulling force on the cable, provides a certain buffer, and prevents the cable from being damaged by pulling.
[0030] Example 2
[0031] Based on Example 1, multiple sets of trapezoidal protective frames 1 are connected according to the road width, as shown in the attached figure. Figure 1 and attached Figure 2As shown, the trapezoidal protective frame 1 has connecting assemblies at both ends. Each connecting assembly includes a first connecting plate 8 and a second connecting plate 12. The first connecting plate 8 and the second connecting plate 12 are installed on the lower and upper side walls of one end of the trapezoidal protective frame 1. The lower and upper side walls of the other end of the trapezoidal protective frame 1 are respectively provided with slots 1 9 and 2 13 for inserting the first connecting plate 8 and the second connecting plate 12. The positions of the first connecting plate 8, the second connecting plate 12, the first slot 9, and the second slot 13 at both ends of the trapezoidal protective frame 1 are replaceable, facilitating adjustments. Cable protection: A connecting bolt 11 passes through the lower side wall of the trapezoidal protective frame 1. The connecting bolt 11 passes through the slot 9 and is connected to the connecting plate 8. A connecting bolt 15 passes through the upper side wall of the trapezoidal protective frame 1. The connecting bolt 15 passes through the slot 13 and is connected to the connecting plate 12. By connecting the connecting bolt 11 to the connecting plate 8 and connecting the connecting bolt 15 to the connecting plate 12, the ends of the two sets of trapezoidal protective frames 1 are connected and connected to each other. Cables can pass through multiple sets of trapezoidal protective frames 1.
[0032] The lower side wall of the trapezoidal protective frame 1 is provided with a groove 10 for the end of the connecting bolt 11 to be embedded, and the upper side wall of the trapezoidal protective frame 1 is provided with a groove 14 for the end of the connecting bolt 25 to be embedded. The ends of the connecting bolt 11 and the connecting bolt 25 are hidden by the groove 10 and the groove 14 to prevent the connecting bolt 11 and the connecting bolt 25 from protruding and making it difficult for the trapezoidal protective frame 1 to fit with the ground and to prevent uneven squeezing damage to the vehicle wheels.
