Description

Technical Field

[0001] The utility model relates to the technical field of bridge laying, in particular to a cable laying bridge for power engineering. Background Technique

[0002] Power engineering refers to the engineering related to the production, transmission, and distribution of electric energy. In a broad sense, it also includes the engineering of applying electricity as power and energy in various fields.

[0003] For example, the Chinese utility model patent with the publication number CN216436719U belongs to the technical field of bridge laying and relates to a cable laying bridge for power engineering. Among them, it includes a bridge and a top plate. The surface of the inner wall of the bridge is fixedly connected with a plurality of telescopic components. One end of the telescopic component is fixedly connected with a support plate. The top and bottom of the inner wall of the support plate are fixedly connected with damping bearings. A rotating shaft is inserted through the damping bearings. Its beneficial effects are that for this cable laying bridge for power engineering, through the rotation of the rotating shaft in the damping bearings, during the wiring process, when pulling the cable, the surface of the cable fits against the auxiliary wheels, and with the help of the rotation of the auxiliary wheels, the wiring efficiency can be improved. At the same time, it can avoid the cable from contacting the surface of the fixed frame, prevent the cable from being damaged, and ensure the use effect of the cable. By setting springs, it can cooperate with the extrusion degree of the cable, and with the help of the movement of the movable rod in the fixed cylinder, it can expand and contract to avoid over-extruding the cable.

[0004] However, there are still some problems. Although it can avoid the cable from contacting the surface of the fixed frame and prevent the cable from being damaged, ensuring the use effect of the cable, the length of the bridge is usually a fixed length, and the installation and disassembly processes are cumbersome. Once installed, it is difficult to flexibly adjust according to actual needs, and it is not convenient to maintain the cable later, which is inconvenient. Therefore, a cable laying bridge for power engineering is proposed to solve the above problems. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a cable laying bridge for power engineering, which has the advantage of high flexibility and solves the problem that the length of the bridge is usually a fixed length and it is difficult to flexibly adjust according to actual needs.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A cable laying bridge for power engineering includes a protective frame. A cover plate is fixedly connected to the top of the protective frame. The inside of the cover plate is slidably connected with a plurality of fixing bolts that are threadedly connected to the protective frame. Two connecting blocks are fixedly arranged on the outer surface of the protective frame.

[0007] On both the left and right sides of the connection block on the back, fixing components are provided. The fixing components are used to fix a plurality of protective frames. A positioning block is slidably connected inside the protective frame. A plurality of rollers are rotatably connected inside the positioning block. A connecting plate is fixed to the front of the connection block on the front side.

[0008] The fixing components include fixing blocks, fixing plates, fixing springs, rotating rods and rotating blocks. The inside of the connection block on the back is slidably connected with the fixing blocks. One side of the two fixing blocks facing away from each other is fixed to the fixing plates. The fixing plates and the connection block on the back are fixed with the fixing springs. The inside of the fixing plates is rotatably connected with the rotating rods penetrating into the inside of the fixing blocks. One side of the two rotating rods facing each other is fixed to the rotating blocks. The rotating blocks penetrate to the outside of the fixing blocks and are slidably connected with the connection block on the back.

[0009] By adopting this technical solution, when the fixing blocks are inserted into the connecting plate, the splicing of the two protective frames can be completed. By rotating the rotating blocks, the rotating blocks can be moved to the outside of the fixing blocks and slidably connected with the connection block, thus ensuring the stability of the fixing blocks.

[0010] Further, heat dissipation holes are formed on the outer surface of the protective frame. Connection holes adapted to the fixing blocks are formed inside the connecting plate. A connection hole adapted to the connecting plate is formed inside the connection block on the back.

[0011] By adopting this technical solution, the provided heat dissipation holes can improve the overall heat dissipation efficiency. The provided connection holes enable the fixing components to be inserted into the connecting plate to complete the fixing of the connecting plate.

[0012] Further, the fixing bolts are external threaded bolts. Threaded holes adapted to the fixing bolts are formed at the top of the protective frame.

[0013] By adopting this technical solution, through the provided external threaded bolts, the protective frame and the cover plate can be conveniently fixed.

[0014] Further, sliding blocks are fixed to both the left and right sides of the positioning block. Sliding grooves adapted to the sliding blocks are formed inside the protective frame.

[0015] By adopting this technical solution, the provided sliding blocks and sliding grooves can ensure the accuracy of the position of the positioning block.

[0016] Further, two positioning rods are fixed to the bottom of the cover plate and are located inside the sliding grooves. The bottom of the positioning rods is in contact with the sliding blocks.

[0017] By adopting this technical solution, the provided positioning rods can ensure the accuracy of the position of the cover plate and can squeeze the sliding blocks, so that the positioning block will not shake.

[0018] Furthermore, control blocks are fixed on the opposite sides of the two rotating rods, and inclined surfaces are provided on the backs of the fixed blocks.

[0019] By adopting this technical solution, the provided inclined surfaces enable the connecting plate to squeeze the fixed blocks when moving forward, facilitating installation.

[0020] Furthermore, mounting holes are formed inside the fixed plate, sponge pads are fixed inside the mounting holes, and the rotating rods are rotatably connected to the inside of the sponge pads.

[0021] By adopting this technical solution, the provided sponge pads can increase the friction force received by the rotating rods during rotation, making the rotating rods not easy to rotate.

[0022] Furthermore, both the fixed blocks and the rotating blocks are rectangular blocks. The length of the rotating block is greater than the width of the fixed block, and the length of the rotating block is less than the length of the fixed block.

[0023] By adopting this technical solution, since the length of the rotating block is greater than the width of the fixed block, when the rotating block rotates, it will move outside the fixed block and thus slidably connect with the connecting block.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The cable laying bridge for power engineering can, according to the length required on site, conveniently splice and install multiple protective frames through the fixing components, so that the overall length can be flexibly adjusted. And when subsequent cable maintenance is needed, after determining the damaged position of the cable, the cover plate can be disassembled by rotating the fixing bolts at the corresponding part, thus eliminating the need to disassemble the entire cover plate. The overall structure is simple, making the overall use more flexible and facilitating subsequent cable maintenance.

[0026] 2. The cable laying bridge for power engineering can complete the disassembly of the positioning block and the protective frame by pulling the positioning block, enabling the replacement of different positioning blocks according to the number of cables to be laid and installed to adapt to different usage environments. And through the provided rollers, the friction force received by the cable when moving inside the positioning block can be reduced, effectively ensuring the safety of the cable and making the overall more practical.

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1 to 3 , in this embodiment, the cable laying bridge for power engineering includes a protective frame 1. Heat dissipation holes 11 are provided on the outer surface of the protective frame 1. The provided heat dissipation holes 11 can improve the overall heat dissipation efficiency. A cover plate 2 is fixed to the top of the protective frame 1. A plurality of fixing bolts 3 that are slidably connected inside the cover plate 2 and threadedly connected to the protective frame 1 are provided. The fixing bolts 3 are external thread bolts. Threaded holes adapted to the fixing bolts 3 are provided at the top of the protective frame 1. By providing the external thread bolts, the protective frame 1 and the cover plate 2 can be conveniently fixed. Two connecting blocks 4 are fixed to the outer surface of the protective frame 1.

[0034] In addition, fixing components 5 are provided on both the left and right sides of the connecting block 4 on the back. The fixing components 5 are used to fix a plurality of protective frames 1. A positioning block 6 is slidably connected inside the protective frame 1. Sliding blocks 9 are fixed to both the left and right sides of the positioning block 6. Sliding grooves 10 slidably connected to the sliding blocks 9 are provided inside the protective frame 1. The provided sliding blocks 9 and sliding grooves 10 can ensure the accuracy of the position of the positioning block 6.

[0035] Furthermore, two positioning rods 14 are fixed to the bottom of the cover plate 2 and are located inside the sliding groove 10. The bottom of the positioning rod 14 is in contact with the sliding block 9. The arranged positioning rods 14 can ensure the position accuracy of the cover plate 2 and can squeeze the sliding block 9, so that the positioning block 6 will not shake. A plurality of rollers 7 are rotatably connected inside the positioning block 6. A connecting plate 8 is fixed to the front of the front connecting block 4. An engaging hole 13 adapted to the connecting plate 8 is formed inside the rear connecting block 4. A connecting hole 12 adapted to the fixing block 501 is formed inside the connecting plate 8. The arranged connecting hole 12 enables the fixing assembly 5 to be inserted into the connecting plate 8 to complete the fixing of the connecting plate 8.

[0036] Generally speaking, by arranging the rollers 7, the friction between the cable and the positioning block 6 can be reduced, and the positioning block 6 can be replaced according to requirements, so that the whole can be adjusted according to the use requirements, and thus the whole is more practical.

[0037] Please refer to Figure 4 , in this embodiment, the fixing assembly 5 includes a fixing block 501, a fixing plate 502, a fixing spring 503, a rotating rod 504 and a rotating block 505. The inside of the rear connecting block 4 is slidably connected with the fixing block 501. The opposite sides of the two fixing blocks 501 are fixed to the fixing plate 502. An inclined surface is provided on the back of the fixing block 501. The arranged inclined surface enables the connecting plate 8 to squeeze the fixing block 501 when moving forward, so that the installation can be carried out conveniently. An installation hole is formed inside the fixing plate 502, and a sponge pad 507 is fixed inside the installation hole. The inside of the sponge pad 507 is rotatably connected with the rotating rod 504. By arranging the sponge pad 507, the friction force received by the rotating rod 504 during rotation can be increased, so that the rotating rod 504 is not easy to rotate.

[0038] In addition, a fixing spring 503 is fixed between the fixing plate 502 and the rear connecting block 4. The inside of the fixing plate 502 is rotatably connected with the rotating rod 504 penetrating into the inside of the fixing block 501. Control blocks 506 are fixed to the opposite sides of the two rotating rods 504. The opposite sides of the two rotating rods 504 are fixed to the rotating block 505. The rotating block 505 penetrates to the outside of the fixing block 501 and is slidably connected with the rear connecting block 4. Both the fixing block 501 and the rotating block 505 are rectangular blocks. The length of the rotating block 505 is greater than the width of the fixing block 501, and the length of the rotating block 505 is less than the length of the fixing block 501. Because the length of the rotating block 505 is greater than the width of the fixing block 501, when the rotating block 505 rotates, it will move to the outside of the fixing block 501 and thus be slidably connected with the connecting block 4.

[0039] Generally speaking, when the fixed block 501 is inserted into the connecting plate 8, the splicing of the two protective frames 1 can be completed. By rotating the rotating block 505, the rotating block 505 can be moved to the outside of the fixed block 501 and slidably connected to the connecting block 4, thus ensuring the stability of the fixed block 501.

[0040] The working principle of the above embodiment is as follows:

[0041] When it is necessary to replace the positioning block 6, by rotating the fixing bolt 3, the fixing bolt 3 can move upward due to the extrusion of the thread, so that the disassembly of the cover plate 2 and the positioning rod 14 can be completed. At this time, the positioning block 6 can be pulled upward to complete the disassembly of the positioning block 6, so that positioning blocks 6 of different shapes can be replaced according to the usage requirements. When it is necessary to splice the two protective frames 1, first rotate the rotating rod 504 to make the rotating block 505 rotate. Since the length of the fixed block 501 is greater than the length of the rotating block 505, the rotating block 505 will move inside the fixed block 501 after rotation. At the same time, since the fixed block 501 is a rectangular block, when the rotating rod 504 rotates, it will not drive the fixed block 501 to rotate. At this time, move the secondary protective frame 1 so that the connecting plate 8 on the secondary protective frame 1 moves into the internal connection hole 13 on the connecting block 4 of the main protective frame 1. When the connecting plate 8 moves, it will contact the inclined surface on the back of the fixed block 501, thereby extruding the fixed block 501, causing the fixed block 501 to move outward from the connecting block 4 and accumulating elastic potential energy in the fixed spring 503. When the connection hole 12 on the connecting plate 8 moves to a position adapted to the fixed block 501, under the push of the fixed spring 503, the fixed block 501 will be inserted into the connecting plate 8, thus completing the splicing of the two protective frames 1. The overall structure is simple, making the overall use more flexible and thus making the whole more practical.
