Description

Technical Field

[0001] The utility model belongs to the technical field related to power grid construction, and in particular relates to a cable erection and lifting device used for power grid construction. Background Art

[0002] The entire power system, consisting of substations and transmission and distribution lines of various voltages, is called a power grid. A power grid comprises three units: substation, transmission, and distribution. The power grid's mission is to transmit and distribute electrical energy and change voltage. Therefore, the construction of a power grid requires the use of appropriate cable-lifting equipment to lift cables.

[0003] However, existing cable erection and lifting devices are not easy to use when lifting cables, which reduces the cable lifting efficiency. At the same time, during the cable lifting process, they do not have the function of abutting and limiting the cable, so the cable is prone to falling off, resulting in cable lifting errors. To this end, we provide a cable erection and lifting device for power grid construction to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cable laying and pulling device for power grid construction, which drives the gathering drum to move by gathering the rope, so as to facilitate the pulling and pulling of the cable. At the same time, the rotation of the tightening wheel can control the abutment of the abutment plate on the cable to ensure that the cable will not fall out easily.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a cable laying and pulling device for power grid construction, comprising a retracting box and a bunching drum located to the left of the retracting box; a rotating plate is provided in the middle position above the retracting box, through holes are provided on the upper and lower end surfaces of the retracting box, a retracting rod rotatably connected to the through hole through a bearing is fixed to the lower end surface of the rotating plate, a retracting rope is wound around the circumference of the retracting rod, a magnetic ring is fixed to the lower end surface of the rotating plate, a positioning ring is provided below the rotating plate, and a metal ring plate adsorbed by the magnetic ring is provided on the upper end surface of the positioning ring;

[0007] Three screw barrels evenly distributed in a ring shape are fixed on the circumference of the tightening cylinder. A tightening wheel is provided at the position corresponding to the screw barrel inside the tightening cylinder. A rotating rod is fixed in the middle of the tightening wheel. An abutment plate is fixed on the lower end surface of the tightening cylinder directly below the screw barrel. A friction rubber rod is fixed on the lower end surface of the abutment plate. Ropes fixed to the middle of the abutment plate are fixed on the circumference of the rotating rod at both ends of the tightening wheel.

[0008] The utility model is further configured such that a spring is fixed to the lower end surface of the positioning ring, and a mounting ring connected to the upper end surface of the retracted wire box is fixed to the lower end surface of the spring.

[0009] The utility model is further configured such that a hanging plate is fixed on the lower end surface of the collection box, a connecting tube connected to the interior of the collection box is fixed on the peripheral side of the collection box, and a ring is fixed on the end of the collection rope passing through the connecting tube.

[0010] The utility model is further configured such that a hanging ring is fixed at a position on the peripheral side of the gathering tube corresponding to the connecting tube, and the gathering rope is connected to the hanging ring through a sleeve.

[0011] The utility model is further configured such that a U-shaped plate rotatably connected to the rotating rod is provided on the circumferential side of the tightening wheel, a screw spirally positioned inside the barrel is provided on the end face of the U-shaped plate, and a connecting plate is fixed to the end of the screw passing through the barrel.

[0012] The utility model is further configured such that the other end of the screw is provided with a T-shaped hole, and the end surface of the U-shaped plate is fixed with a T-shaped rod that rotatably matches the T-shaped hole.

[0015] The utility model has the following beneficial effects:

[0016] When the utility model is in use, the rotating plate is rotated, thereby the rotating plate drives the gathering rod to rotate, and then the gathering rod gathers or loosens the gathering rope, so that the gathering rope drives the gathering tube to move, and the gathering tube directly drives the cable to move, thereby pulling the cable up and improving the pulling efficiency.

[0017] When the utility model is in use, the tightening tube is sleeved on the position of the cable end, and the tightening wheel is connected to the outer side of the cable, and the friction rubber rod at the end of the abutment plate is connected to the outer side of the cable.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Specific embodiment 1

[0031] See also Figure 1-8 The utility model is a cable laying and pulling device used in power grid construction. The gathering rope 6 drives the gathering drum 2 to move, which is convenient for pulling the cable. At the same time, the rotation of the tightening wheel 3 can control the abutment of the abutment plate 7 on the cable to ensure that the cable will not fall out easily.

[0032] Specifically, a folding box 1 and a gathering tube 2 located on the left side of the folding box 1; a rotating plate 4 is provided in the middle position above the folding box 1, and a through hole 102 is provided on the upper and lower end surfaces of the folding box 1. A folding rod 402 is fixed on the lower end surface of the rotating plate 4 to be rotatably connected to the through hole 102 through a bearing, and a folding rope 6 is wound around the circumference of the folding rod 402. A magnetic ring 401 is fixed on the lower end surface of the rotating plate 4, and a positioning ring 5 is provided below the rotating plate 4. The upper end surface of the positioning ring 5 is provided with a magnetic ring 401. Adsorbed metal ring plate 501; three screw barrels 201 evenly distributed in a ring shape are fixed on the circumferential side of the tightening cylinder 2, and tightening wheels 3 are provided at the positions of the screw barrels 201 inside the tightening cylinder 2, and a rotating rod 304 is fixed in the middle of the tightening wheel 3. Abutment plates 7 are fixed on the lower end surface of the tightening cylinder 2 directly below the screw barrel 201, and a friction rubber rod 702 is fixed on the lower end surface of the abutment plate 7. Ropes 305 fixedly connected to the middle of the abutment plate 7 are fixed on the circumferential sides of the rotating rods 304 at both ends of the tightening wheel 3.

[0033] The operation process of this embodiment is as follows: through the arrangement and use of the above-mentioned structure, when the cable needs to be erected and lifted, the tightening cylinder 2 can be placed at the position of the cable end, and the tightening wheel 3 can be connected to the surface side of the cable, and the friction rubber rod 702 at the end of the abutment plate 7 can be connected to the surface side of the cable. Therefore, when the cable tends to slide out of the interior of the tightening cylinder 2, the cable will drive the tightening wheel 3 to rotate, thereby the tightening wheel 3 tightens the rope 305 through the rotating rod 304, and the rope 305 pulls the abutment plate 7, so that the abutment plate 7 is tightly abutted against the cable, so that the cable is tightened in the tightening cylinder. 2 cannot be detached. At the same time, when it is necessary to adjust the distance between the gathering cylinder 2 and the gathering box 1, the rotating plate 4 is rotated, thereby the rotating plate 4 will drive the gathering rod 402 to rotate, and then the gathering rod 402 will gather or loosen the gathering rope 6, so that the gathering rope 6 will drive the gathering cylinder 2 to move, so that the gathering cylinder 2 will directly drive the cable to move, thereby pulling the cable. In order to ensure that the rotating plate 4 does not rotate at will, the spring 503 is used to push the positioning ring 5, so that the positioning ring 5 pushes the metal ring and the magnetic ring 401 to be adsorbed, to ensure that the rotating plate 4 does not rotate at will. Specific embodiment 2

[0034] See also Figure 2 、 4 , 5, 8, on the basis of the specific embodiment 1, the gathering rope 6 is stably connected to the gathering cylinder 2, so as to facilitate the gathering rope 6 to pull the gathering cylinder 2.

[0035] Specifically, a spring 503 is fixed to the lower end face of the positioning ring 5, and a mounting ring 502 connected to the upper end face of the gathering wire box 1 is fixed to the lower end face of the spring 503. A hanging plate 101 is fixed to the lower end face of the gathering wire box 1, and a connecting tube 103 connected to the interior thereof is fixed to the peripheral side of the gathering wire box 1. A ring 601 is fixed to the end of the gathering rope 6 passing through the connecting tube 103, and a hanging ring 202 is fixed to the peripheral side of the gathering tube 2 at a position corresponding to the connecting tube 103. The gathering rope 6 is connected to the hanging ring 202 through the ring 601.

[0036] The operating process of this embodiment is: due to the connection relationship between the ring 601 and the hanging ring 202, the gathering rope 6 is stably connected to the gathering tube 2, so that the gathering rope 6 pulls the gathering tube 2. At the same time, when the staff carries the gathering wire box 1, they can use the hanging plate 101 to hang the gathering wire box 1 on the safety clothing to carry the gathering wire box 1. Specific embodiment three

[0037] See also Figure 3 、 6 7. Based on the specific embodiment 1, the screw 302 is rotated in the inner position of the screw barrel 201 so that the position of the tightening wheel 3 can be adjusted according to the diameter of the cable.

[0038] Specifically, a U-shaped plate 301 rotatably connected to a rotating rod 304 is provided on the circumferential side of the tightening wheel 3, and a screw 302 spirally arranged in an internal position of the screw barrel 201 is provided on the end face of the U-shaped plate 301, and a connecting plate 303 is fixed to the end of the screw 302 passing through the screw barrel 201, and a T-shaped hole 306 is provided at the other end of the screw 302, and a T-shaped rod 307 rotatably matched with the T-shaped hole 306 is fixed on the end face of the U-shaped plate 301, and an axis block 203 is fixed at the position of the lower end face of the tightening cylinder 2 corresponding to the abutment plate 7, and an axis rod 204 is fixed on both end faces of the axis block 203, and the upper end of the abutment plate 7 is sleeved on the circumferential side of the axis block 203 through the provided rotation groove 701, and the axis rod 204 is rotatably set on the axis hole of the abutment plate 7.

[0039] The operation process of this embodiment is as follows: in order to enable the take-up wheel 3 to be suitable for cables of different calibers, the connecting plate 303 can be rotated, and then the connecting plate 303 will drive the screw 302 to rotate inside the screw barrel 201, thereby the screw 302 will drive the U-shaped plate 301 to move, and thereby control the take-up wheel 3 to abut against the surface side of the cable. At the same time, when the take-up wheel 3 moves, the take-up wheel 3 will drive the abutment plate 7 to rotate through the rope 305, so that the abutment plate 7 will rotate with the shaft block 203 and the shaft 204 as the axis.
