Description

Technical Field

[0001] The invention belongs to the technical field of municipal cable construction, and in particular relates to a power cable laying device with adjustable drop and slope. Background Art

[0002] Power cables are widely used in power distribution lines. When laying power cables, how to ensure safety, speed and reduce construction labor intensity is a key node. In the existing cable laying process, 110kV or 220kV high-voltage cables are expensive and delicate products, and are often laid outdoors or in poor environmental conditions.

[0003] When the cable passes through the drop, it will bend greatly due to its own gravity. If there is no measure to adjust the drop, the cable may be subjected to bending stress exceeding its allowable bending radius in a short period of time, which can easily make the cable bending radius too small, causing cracks in the cable insulation layer, thus affecting the insulation performance of the cable and increasing the risk of cable failure.

[0006] Furthermore, a lifting assembly is provided at the bottom of the reel, and the lifting assembly includes two push plates. The outer shapes of the two push plates are arc-shaped, and push plates are provided at the bottom of the two push plates. The tops of the two push plates are arc-shaped concave surfaces, and the arc-shaped concave surfaces at the tops of the two push plates are in contact with the push plates, and the bottoms of the two push plates are fixedly connected to the bottom inner wall of the support.

[0009] Furthermore, a connecting rod is fixedly connected to the back side of the bracket, and a fixing component is provided on the side of the connecting rod close to the support. The fixing component includes an arc block fixedly connected to the back side of the support, and a limiting groove is provided on the side of the arc block close to the connecting rod.

[0010] Furthermore, a fixing block is fixedly connected to a side of the connecting rod away from the arc block, a screw rod is threadedly connected to an inner wall of the fixing block, and an end of the screw rod close to the arc block is fixedly connected to a limiting block.

[0011] Furthermore, the side of the limit block away from the screw rod passes through the side wall of the connecting rod and extends to the outside, the extended end of the limit block is plugged into the inner wall of the limit groove, and the end of the screw rod away from the limit block is fixedly connected to the turning handle.

As the screw rod rotates, the screw rod pushes the limit block to be inserted into the inner wall of the limit groove opened inside the arc block, thereby fixing the connecting rod to the surface of the arc block. Since the connecting rod and the bracket are fixed together, the bracket is fixed and cannot rotate, which avoids the bracket being pressed down and moved due to the excessive weight of the cable itself. The cable can be effectively supported to keep it in a suitable position in the air, thereby ensuring that the cable can be laid smoothly.

The inner walls of the two vertical frames 203 are rotatably connected to three sliding bars 204, and the three sliding bars 204 are arranged in parallel up and down. According to the degree of drop of the reel cable 102, the sliding bars 204 at different heights are passed through to adjust the release angle and tension of the cable 102 to ensure that the cable 102 can smoothly cross areas of different heights, so that the cable 102 laying project can be smoothly carried out in complex terrain without being restricted by the drop problem of the terrain.

[0022] A lifting assembly 3 is provided at the bottom of the reel 101, and the lifting assembly 3 includes two push plates 301. The two push plates 301 are arc-shaped in shape, and push plates 301 are provided at the bottom of the two push plates 301. The tops of the two push plates 301 are arc-shaped recessed surfaces, and the arc-shaped recessed surfaces at the tops of the two push plates 301 fit with the push plates 301. The bottoms of the two push plates 301 are fixedly connected to the bottom inner wall of the support 1, and the reel 101 is pushed from the position of the inclined plate 104 to the top of the push plate 301. The inclined plate 104 provides convenience when pushing the reel 101, saving the staff's effort.

[0023] The two push plates 301 are fixedly connected to a support plate 302 on one side close to each other, a motor 2 303 is fixedly connected to the front of the support 1, a bidirectional threaded rod 304 is fixedly connected to the output end of the motor 2 303, the front and back sides of the bidirectional threaded rod 304 are rotatably connected to the inner wall of the support 1, and the outer surface of the bidirectional threaded rod 304 is threadedly connected to two sliders 305, the two sliders 305 are symmetrically arranged, the side walls of the two sliders 305 are rotatably connected to support rods 306, and the ends of the two support rods 306 away from the sliders 305 are rotatably connected to the connecting blocks 3 07. The two connecting blocks 307 are fixedly connected to the bottom of the support plate 302 on one side away from the slider 305. As the bidirectional threaded rod 304 rotates, the two sliders 305 on its surface approach each other.

The operator does not need to lift the heavy reel 101 to the installation height of the support 1 with great effort, making the installation process more convenient and efficient, and reducing the manpower required for installation.

[0024] A connecting rod 205 is fixedly connected to the back of the bracket 201, and a fixing component 4 is provided on the side of the connecting rod 205 close to the support 1. The fixing component 4 includes an arc block 401 fixedly connected to the back of the support 1, and a limiting groove 402 is provided on the side of the arc block 401 close to the connecting rod 205. A moving block 403 is fixedly connected to the side of the connecting rod 205 close to the limiting groove 402. The outer surface of the moving block 403 is slidably connected to the inner wall of the limiting groove 402. As the bracket 201 rotates, the connecting rod 205 is driven to rotate, and the moving block 403 arranged on the side wall of the connecting rod 205 slides inside the limiting groove 402.

[0025] A fixed block 405 is fixedly connected to the side of the connecting rod 205 away from the arc block 401, and a screw rod 406 is threadedly connected to the inner wall of the fixed block 405. An end of the screw rod 406 close to the arc block 401 is fixedly connected to the limiting block 404. Moving the fixed block 405 can control the connecting rod 205 to slide along the limiting groove opened in the arc block 401, thereby controlling the rotation of the bracket 201.

[0026] The side of the limit block 404 away from the screw rod 406 passes through the side wall of the connecting rod 205 and extends to the outside. The extended end of the limit block 404 is plugged into the inner wall of the limit groove 402. The end of the screw rod 406 away from the limit block 404 is fixedly connected to a turning handle 407. The screw rod 406 is driven to rotate clockwise by turning the turning handle 407. As the screw rod 406 rotates, the screw rod 406 pushes the limit block 404 to insert into the inner wall of the limit groove 402 opened inside the arc block 401, thereby fixing the connecting rod 205 on the surface of the arc block 401. The bracket 201 is fixed and cannot rotate, which prevents the bracket 201 from being pressed down and moved due to the excessive weight of the cable 102 itself. The cable 102 can be effectively supported to keep it in a suitable position in the air, thereby ensuring that the cable 102 can be laid smoothly.

[0027] A specific application of this embodiment is as follows: the cable 102 is wound on the surface of the reel 101. When the cable 102 needs to be released, the support 1 is first placed in a fixed position, and the reel 101 is pushed from the position of the inclined plate 104 to the top of the push plate 301. The inclined plate 104 provides convenience for pushing the reel 101 and saves the staff's effort. When the reel 101 falls on the top of the push plate 301, the start motor 2 303 drives the bidirectional threaded rod 304 to rotate clockwise. As the bidirectional threaded rod 304 rotates, the two sliders 305 on its surface approach each other. When the two sliders 305 approach each other, the support plate 302 is pushed upward by the support rod 306. Since the two sides of the support plate 302 are connected to the push plate 301, the support plate 302 At the same time, the movement will drive the push plates 301 on both sides to move upward, thereby pushing the reel 101 placed on the top of the push plates 301 to move upward, and the reel 101 is moved to the position of the mounting hole set in the support 1 along with the push plates 301, and the output end of the motor 103 is connected to the reel 101. The reel 101 is installed inside the support 1. At this time, the motor 2 303 is used to drive the two-way threaded rod 304 to rotate counterclockwise, and the push plates 301 on both sides are moved downward away from the bottom of the reel 101 without affecting the rotation of the reel 101. The operator does not need to lift the heavy reel 101 to the installation height of the support 1 with great effort, making the installation process more convenient and efficient, reducing the manpower required for installation, and also reducing the safety risks that may be caused by manual handling.

[0028] One end of the cable 102 is taken out from the surface of the reel 101, and the cable 102 passes through the top of the pulley 202 and then through the bottom of the slide bar to be pulled to the position where the cable needs to be laid. The drop of the cable 102 taken out from the reel 101 is adjusted according to the on-site construction environment, and the bracket 201 is rotated to adjust the position of the pulley 202. There are three slide bars 204, which can pass through slide bars 204 of different heights according to the drop degree of the reel cable 102, and adjust the release angle and tension of the cable 102 to ensure that the cable 102 can smoothly cross areas of different heights, so that the cable 102 laying project can be carried out smoothly in complex terrain without being restricted by the drop problem of the terrain.

[0029] After adjusting the position of the pulley 202, the screw rod 406 is driven to rotate clockwise by turning the handle 407. As the screw rod 406 rotates, the screw rod 406 pushes the limit block 404 to insert into the inner wall of the limit groove 402 opened inside the arc block 401, thereby fixing the connecting rod 205 on the surface of the arc block 401. Since the connecting rod 205 and the bracket 201 are fixed together, the bracket 201 is fixed and cannot rotate, which prevents the bracket 201 from being pressed down and moved due to the excessive weight of the cable 102 itself. The cable 102 can be effectively supported to keep it in a suitable position in the air, thereby ensuring that the cable 102 can be laid smoothly.
