Description

Technical Field

[0001] This utility model relates to the field of cable support technology, specifically a cable support for use at the construction site of power transmission line projects. Background Technology

[0002] Transmission line engineering is a complex field of electrical engineering, mainly involving the design, construction and maintenance of transmission systems for electricity from power plants to substations and then to various power consumption areas. During the cable laying process, it is necessary to pull and lay the cables wrapped on the cable reels, so cable supports are needed to assist in the laying and laying of cables.

[0003] In existing cable laying processes, workers are required to pull the cable to a certain length for installation. However, in practice, the cable itself has a certain weight, and the longer the cable, the more strenuous the pulling becomes, resulting in slower cable laying efficiency, impacting cable construction, and increasing the pulling effort required by workers. Therefore, this paper proposes a cable support for power transmission line construction sites to solve the aforementioned problems. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a cable support for power transmission line construction sites, solving the problem that manual pulling is laborious during cable transportation and laying, and that the increasing weight of the cable as the cable length gradually increases leads to slower cable laying efficiency and affects work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable support for a power transmission line construction site, comprising a fixing plate, a fixing column fixedly connected to the upper end of the fixing plate, a groove formed on the fixing column, a drive roller rotatably connected within the groove, a positioning plate fixedly connected to one side of the fixing column, a drive motor fixedly connected to the upper end of the positioning plate, a drive shaft connected to the output end of the drive motor, the drive shaft fixedly connected to the drive roller, a driven roller above the drive roller, a fixing rod rotatably connected to the center of the driven roller, movable grooves formed on both sides of the inner wall of the groove, a sliding connection between the fixing rod and the fixing column, connecting blocks fixedly connected to both ends of the fixing rod, two symmetrical guide rods fixedly connected to the upper end of the connecting blocks, two symmetrical limiting plates fixedly connected to the upper end of the fixing column, the guide rods slidably connected to the limiting plates, a spring sleeved on the outer surface of the guide rod, and both ends of the spring fixedly connected to the limiting plates and the connecting blocks respectively.

[0006] The beneficial effects of this utility model are as follows: by moving the two connecting blocks, the fixed rod and the driven roller move upward, causing the guide rod to slide on the limiting plate, compressing the spring, and allowing the cable to pass between the active roller and the driven roller. With the spring's rebound, the cable is limited. Under the action of the drive motor, the rotating shaft drives the active roller to rotate. With the use of the driven roller, the cable is quickly transported, which facilitates rapid and efficient cable transport and improves work efficiency.

[0007] In order to limit the movement of the connecting block;

[0008] As a further improvement to the above technical solution: two symmetrical guide grooves are provided on the side of the fixed column that contacts the connecting block, and a guide block is slidably connected in the guide groove, and the guide block is fixedly connected to the connecting block;

[0009] The beneficial effects of this improvement are: by using guide grooves and guide blocks, the connecting block can be guided, ensuring that the connecting block always fits the fixed column for stable lifting and lowering during the lifting process, thus ensuring sufficient stability of the connecting block.

[0010] In order to fix the cable bracket;

[0011] As a further improvement to the above technical solution: a fixing block is provided below the connecting block, the fixing block is fixedly connected to the fixing column, an electric telescopic column is fixedly connected to the fixing block, a positioning cone is fixedly connected to the movable end of the electric telescopic column, and two symmetrical clearance grooves are opened on the fixing plate, with the two clearance grooves corresponding one-to-one with the two positioning cones.

[0012] The beneficial effects of this improvement are as follows: by using the fixing block, the electric telescopic column can be fixed to ensure its stability. In conjunction with the use of the electric telescopic column, the electric telescopic column moves towards the ground with the positioning cone, so that the positioning cone contacts the ground, thereby ensuring the stability of the cable bracket and preventing the cable bracket from shifting or shaking randomly during static placement.

[0013] In order to provide power output between cables;

[0014] As a further improvement to the above technical solution: a storage battery is fixedly connected to the upper surface of the fixed plate, and a charging port is provided on one side of the storage battery;

[0015] The beneficial effects of this improvement are: by using a storage battery, power output can be provided between cables to ensure the normal operation of the cable support, and with the use of the charging port, the storage battery can be charged to ensure sufficient power.

[0016] To enable the auxiliary drive roller and driven roller to transport the cable;

[0017] As a further improvement to the above technical solution: rubber rings are fixedly connected to the outer walls of both the driving roller and the driven roller;

[0018] The beneficial effects of this improvement are: by using a rubber ring, a greater frictional force can be generated between the rubber ring and the cable, thereby assisting the driving roller and driven roller in conveying the cable and ensuring the stability of cable conveying.

[0019] In order to protect the spring;

[0020] As a further improvement to the above technical solution: an elastic hose is sleeved on the outer surface of the spring, and the two ends of the elastic hose are fixedly connected to the limiting plate and the connecting block, respectively;

[0021] The beneficial effects of this improvement are: by using a flexible hose, the spring can be protected, preventing it from rusting and effectively extending its service life.

[0022] In order to enable flexible movement of the cable support;

[0023] As a further improvement to the above technical solution: a handle is fixedly connected to the upper surface of the fixed plate, and casters are fixedly connected to the four corners of the lower surface of the fixed plate;

[0024] The beneficial effects of this improvement are: the use of handles and casters allows for flexible movement of the cable bracket, making it easier to control the direction of movement and facilitating operation by staff.

[0025] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0034] like Figures 1 to 6As shown in the figure, this utility model provides a cable support for a power transmission line construction site, including a fixing plate 1. A fixing column 11 is fixedly connected to the upper end of the fixing plate 1. A groove 12 is provided on the fixing column 11, and a drive roller 13 is rotatably connected in the groove 12. A positioning plate 14 is fixedly connected to one side of the fixing column 11, and a drive motor 15 is fixedly connected to the upper end of the positioning plate 14. The positioning plate 14 can fix the drive motor 15 to ensure the stable output of the drive motor 15. The output end of the drive motor 15 is connected to a drive shaft 16, which is fixedly connected to the drive roller 13. A driven roller 17 is provided above the drive roller 13. By using the drive motor 15, the shaft drives the drive roller 13 to rotate. With the use of the driven roller 17, the cable support is adjusted to the power supply. The cable is conveyed by a fixed rod 18 rotatably connected to the center of the driven roller 17. Movable grooves 19 are provided on the inner walls of both sides of the groove 12. The fixed rod 18 is slidably connected to the fixed column 11. Connecting blocks 20 are fixedly connected to both ends of the fixed rod 18. Two symmetrical guide rods 21 are fixedly connected to the upper surface of the connecting block 20. Two symmetrical limiting plates 22 are fixedly connected to the upper surface of the fixed column 11. The guide rods 21 are slidably connected to the limiting plates 22. Springs 23 are sleeved on the outer surface of the guide rods 21. The two ends of the springs 23 are fixedly connected to the limiting plates 22 and the connecting blocks 20, respectively. The lifting of the two connecting blocks 20 can move their corresponding guide rods 21 upwards, causing the connecting blocks 20 to compress the springs 23, thus causing the two connecting blocks 20 to move upwards. The fixed rod 18 and the driven roller 17 move upward, increasing the distance between the driving roller 13 and the driven roller 17, facilitating the cable's passage through them and limiting its movement. Two symmetrical guide grooves 31 are provided on the side of the fixed column 11 that contacts the connecting block 20. Guide blocks 32 are slidably connected within the guide grooves 31 and are fixedly connected to the connecting block 20. The use of the four guide grooves 31 and four guide blocks 32 guides the corresponding connecting blocks 20, ensuring that the connecting blocks 20 always slide up and down in contact with the fixed column 11. A fixed block 41 is located below the connecting block 20 and is fixedly connected to the fixed column 11. An electric telescopic column 42 is fixedly connected to the fixed block 41, with its movable end fixed. The cable support is connected to a positioning cone 43. Two symmetrical clearance grooves 44 are provided on the fixing plate 1, corresponding one-to-one with the two positioning cones 43. By extending two electric telescopic columns 42, the corresponding positioning cones 43 can be moved downwards, passing through the clearance grooves 44 and contacting the ground, thereby fixing the position of the cable support. A battery 51 is fixedly connected to the upper surface of the fixing plate 1. A charging port 52 is provided on one side of the battery 51. The battery 51 provides power to the cable support, and the charging port 52 charges the battery 51, ensuring sufficient power. Rubber rings 61 are fixedly connected to the outer walls of both the driving roller 13 and the driven roller 17.The use of rubber rings 61 on the active tube and driven roller 17 increases the friction between the cable and the conductor, facilitating cable transport and protecting the cable surface from scratches. An elastic hose 71 is fitted over the outer surface of the spring 23, with both ends fixedly connected to the limiting plate 22 and the connecting block 20, respectively. The use of two elastic hoses 71 protects the spring 23, extending its service life. A handle 81 is fixedly connected to the upper surface of the fixing plate 1, and casters 82 are fixedly connected to the four corners of the lower surface of the fixing plate 1. The use of the four casters 82 and the handle 81 allows for flexible movement of the cable support, improving its flexibility.

[0035] The working principle and usage process of this utility model are as follows: First, the cable support can be flexibly moved to the desired position using four universal wheels 82 and a handle 81. Then, the extension of two electric telescopic columns 42 allows two positioning cones 43 to pass through their respective clearance grooves 44, bringing them into contact with the ground and fixing the cable support. The movement of two connecting blocks 20 causes them to move upwards along with their respective guide rods 21, compressing the spring 23. This causes the connecting blocks 20, along with the fixing rod 18 and the driven roller 17, to move upwards, increasing the distance between the driving roller 13 and the driven roller 17, facilitating the cable's passage through them. The spring 23's rebound limits the cable's movement on the driven roller 17. Under the action of the drive motor 15, the rotating shaft rotates, carrying the driving roller 13, for rapid cable transport, improving cable laying efficiency. This completes the entire cable support usage process.
