Description

Technical Field

[0001] This utility model relates to the field of high-voltage cable laying tooling technology, and in particular to a tool for improving the efficiency of high-voltage cable laying. Background Technology

[0002] High-voltage cables in photovoltaic fields are generally buried underground. To facilitate cable laying, cable trenches are usually designed to run along main roads. In addition, the cables are all shipped as a whole on cable reels. To avoid the cables being coiled during the laying process, the radial force of the cables wrapped around the reels needs to be eliminated during the laying process so that the cables can be pulled out in a free state and laid in a straight line in the cable trench. The existing technology of dragging the cables along the ground is very easy to damage the outer PVC sheath, and the laying efficiency is low due to friction.

[0003] Therefore, it is necessary to develop a tool to improve the efficiency of high-voltage cable laying to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to design a tool to improve the efficiency of high-voltage cable laying in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A tool for improving the efficiency of high-voltage cable laying includes: Upper support; the cable reel is placed horizontally on top of the upper support; Lower support structure; Bearing; the center of the upper support is fixedly fitted onto the outer ring of the bearing; the center of the lower support is connected to the inner ring of the bearing; Multiple second pulleys; multiple second pulleys are installed on the truck-mounted crane and hook respectively according to the cable laying direction, and the cable reel is placed in the cable trench after passing over the second pulleys on the truck-mounted crane and hook.

[0006] The beneficial effects of this utility model are as follows: In this application, the cable reel is placed on top of the upper support, which can rotate relative to the lower support via bearings. Therefore, the cable reel can rotate to output the cable. This eliminates the radial force on the cable wound on the circular frame, making cable output convenient. In addition, by setting multiple second pulleys and installing them on the truck crane and hook, the cable is placed in the cable trench after passing over the second pulleys, minimizing friction damage to the outer PVC sheath caused by the cable touching the ground. The rolling cooperation between the second pulleys and the cable makes it easier to pull out the cable. Attached Figure Description

[0015] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figure 1 and 2 As shown in Figure 4, a tool for improving the efficiency of high-voltage cable laying includes: Upper support; the cable reel is placed horizontally on top of the upper support; Lower support structure; Bearing 1; the center of the upper bracket is fixedly fitted onto the outer ring of bearing 1; the center of the lower bracket is connected to the inner ring of bearing 1; Multiple second pulleys 11 are installed on the truck crane and hook respectively according to the laying direction of the cable 19. The cable 19 of the cable reel passes around the second pulleys 11 on the truck crane and hook and is placed in the cable 19 trench.

[0017] like Figure 1 and 2As shown, the upper support includes a first annular plate 2, a first mounting ring 3, a second mounting ring 4, and multiple first support rods 5. The lower support includes a second annular plate 6, a third mounting ring 7, a fourth mounting ring 8, and multiple second support rods 9. The first annular plate 2 is placed inside the first mounting ring 3, and the first mounting ring 3 is placed inside the second mounting ring 4. The first annular plate 2, the first mounting ring 3, and the second mounting ring 4 are placed on the same horizontal plane. The first annular plate 2, the first mounting ring 3, and the second mounting ring 4 are all coaxially aligned with the bearing 1. The first end of the first support rod 5 is connected to the outer wall of the first annular plate 2, and the middle part of the first support rod 5 is connected to the first mounting ring 3. The second end of rod 5 is connected to the second mounting ring 4. Multiple first support rods 5 are radially distributed around the axis of bearing 1. The second annular plate 6 is placed inside the third mounting ring 7, and the third mounting ring 7 is placed inside the fourth mounting ring 8. The second annular plate 6, the third mounting ring 7, and the fourth mounting ring 8 are placed on the same horizontal plane and are coaxial with bearing 1. The first end of the second support rod 9 is connected to the outer wall of the second annular plate 6, the middle part of the second support rod 9 is connected to the third mounting ring 7, and the second end of the second support rod 9 is connected to the fourth mounting ring 8. Multiple second support rods 9 are radially distributed around the axis of bearing 1. The upper support uses the structure of first annular plate 2, first mounting ring 3, second mounting ring 4, and multiple first support rods 5, while the lower support uses the structure of second annular plate 6, third mounting ring 7, fourth mounting ring 8, and multiple second support rods 9, ultimately forming a stable structure between the upper and lower supports.

[0018] like Figure 1 and 2 As shown, the first annular plate 2 is fixedly mounted on the outer ring of the bearing 1, and the second annular plate 6 is fixedly mounted on the inner ring of the bearing 1.

[0019] like Figure 1 As shown, the top of the outer ring of bearing 1 protrudes from the top surface of the first annular plate 2, and the central through hole of the cable reel is fitted onto the top of the outer ring of bearing 1. This structural design allows the cable reel to be quickly centered, increasing construction efficiency.

[0020] like Figure 1 and 2 As shown, the cable reel and bearing 1 are arranged coaxially.

[0021] like Figure 2 As shown, multiple first support rods 5 and multiple second support rods 9 are radially evenly distributed around the axis of bearing 1. This structural design ensures the structural stability of the upper and lower supports.

[0022] like Figure 1 and 2As shown, the tool for improving the laying efficiency of high-voltage cable 19 also includes multiple first pulleys 10. The multiple first pulleys 10 are arranged in two groups. The fixed ends of each group of first pulleys 10 are evenly installed on the first mounting ring 3 and the second mounting ring 4. The rollers of each group of first pulleys 10 are respectively connected to the bottom of the first mounting ring 3 and the bottom of the second mounting ring 4 in a rolling connection.

[0023] like Figure 2 As shown, in some embodiments, there are multiple intersection points between the second support rod 9 and the third mounting ring 7 and the fourth mounting ring 8, and multiple first pulleys 10 are installed at multiple intersection points. The rollers of the first pulleys 10 can roll in a ring at the bottom of the first mounting ring 3 and the second mounting ring 4, which further ensures the stability of the support for the upper bracket and the cable reel placed on it.

[0024] like Figure 1 As shown, the tool for improving the laying efficiency of high-voltage cable 19 also includes a braking device 12, which is mounted on the top of the second annular plate 6 and is used to brake the outer ring of the bearing 1.

[0025] like Figure 4 As shown, the braking device 12 includes a rubber friction plate 13, a mounting bracket 14, a pry bar 15, a rotating sleeve 16, and a rotating shaft 17. The rubber friction plate 13 is mounted on the mounting bracket 14, positioned close to the outer ring of the bearing 1. The mounting bracket 14 is mounted on the first end of the pry bar 15. The rotating sleeve 16 is vertically mounted on the top of the second annular plate 6. The upper end of the rotating shaft 17 is connected to the pry bar 15, with the connection point close to the first end of the pry bar 15. The rotating shaft is rotatably inserted into the rotating sleeve 16. The second end of the pry bar 15 extends outward from the fourth mounting ring 8. When braking the rotation of the cable reel is required, the pry bar 15 is pushed outward, causing the rotating shaft 17 on the pry bar 15 to rotate around the rotating sleeve 16. The first end of the pry bar 15 drives the rubber friction plate 13 to press against the outer ring of the bearing 1, thus braking the outer ring of the bearing 1 through friction. In some embodiments, the inner wall of the rubber friction plate 13 matches the outer wall of the outer ring of the bearing 1 in shape, both being arc-shaped.

[0026] like Figure 4 As shown, a handle 18 is installed on the outer side of the second end of the pry bar 15. The purpose of the handle 18 is to provide greater friction for easier gripping by the operator.

[0027] In some embodiments, the rollers of the first pulley 10 and the second pulley 11 are both made of plastic, and the opening size of the rollers matches the outer diameter of the cable 19.

[0028] This utility model is used in conjunction with a truck-mounted crane. First, the truck-mounted crane is used to place this tool flat on the crane's box plate and level it. Then, the truck-mounted crane is used to place the cable reel flat on the laying tool. The central through hole of the cable reel is fitted onto the top of the outer ring of the bearing 1. The cable reel and the bearing 1 are concentric. Multiple second pulleys 11 are fixed in the direction of the cable 19 outlet. The cable 19 passes through the multiple second pulleys 11 and passes through the pulley at the front end of the truck-mounted crane boom and is pulled out. The truck-mounted crane boom is used to accurately place the end of the cable 19 at the designed position. At the same time, the truck-mounted crane is started and moves forward at a constant speed. The cable reel rotates at a constant speed and gradually puts the cable 19 into the pre-dug cable trench. When the distance between the cable trench and the road changes and the cable 19 cannot enter the trench, it is only necessary to manually pull the cable 19 out of the trench into the trench in time. Therefore, it is simple, efficient and time-saving. After using this tool, the quality of the cable 19 is easy to control and the overall linearity after laying is better.

[0029] This invention firstly eliminates the radial force on the cable 19, making the cable 19 linear and aesthetically pleasing during installation. Secondly, it eliminates the problem of uneven stress on the inner and outer surfaces of the cable 19 during mechanical dragging, which could damage the outer PVC sheath and ensure that the insulation quality of the cable 19 is not affected. Thirdly, it improves the efficiency of human and machine construction, achieving good economic and practical results.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
