Description

Technical Field

[0001] This invention relates to the field of cable laying technology, and more specifically to a cable laying device. Background Technology

[0002] Cable laying devices are specialized equipment used in power line construction to support and release cable reels. Their core function is to ensure the cable is laid smoothly, avoiding tangling, knots, or mechanical damage, while also improving construction efficiency. The conventional structure of a cable laying device mainly includes a cable reel and a support frame, relying on manual traction or power drive to rotate the reel and release the cable.

[0003] However, the aforementioned cable laying devices still have significant technical shortcomings in actual construction applications. The terrain where cables are laid often has varying elevations, and the existing cable laying devices have fixed reel installation heights, or only offer manual pre-adjustment capabilities before installation. They cannot dynamically adjust the reel height according to changes in terrain during the laying process. In other words, once the device is in place and operation begins, the reel height is locked, making it impossible to adjust the reel height accordingly. This can lead to cable bending due to elevation differences during laying. In extreme cases, this forced bending caused by elevation differences can cause excessive stretching or even breakage of the cable's internal conductors, damage to the insulation layer, or sheath cracking, resulting in mechanical damage. Such mechanical damage severely reduces the cable's electrical performance and service life, and may even trigger discharge breakdown faults, posing significant safety hazards for subsequent operation.

[0004] Therefore, how to provide a technical solution that can adjust the height of the cable laying device reel at any time to effectively avoid cable bending damage caused by terrain height differences is a technical problem that urgently needs to be solved in the field of cable construction. Summary of the Invention

[0005] The purpose of this invention is to provide a cable laying device, which at least partially solves one of the technical problems in the related art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cable laying device includes a cable reel and support frames located on both sides of the cable reel. The left and right ends of the cable reel are respectively mounted on the support frames via position adjustment mechanisms. The position adjustment mechanism includes a vertical guide rail and a vertical moving mechanism disposed on the support frame. The vertical guide rail extends in the vertical direction and is fixedly connected to the support frame. A vertical moving slider is provided on the vertical guide rail and slidably connected thereto. The vertical moving mechanism extends in the vertical direction. The fixed part of the vertical moving mechanism is fixedly connected to the support frame, and the moving part of the vertical moving mechanism is connected to the vertical moving slider. The inner side of the vertically moving slider is fixed with a support plate. The support plate is equipped with a horizontal moving mechanism that extends in the left and right direction. The fixed part of the horizontal moving mechanism is rotatably connected to the support plate, and the moving part of the horizontal moving mechanism is fixedly installed with a clamping plate. The two clamping plates on the left and right form a clamping mechanism for the line plate.

[0007] Furthermore, the vertical moving mechanism is a first cylinder extending in the up-down direction, the cylinder barrel of the first cylinder is fixedly connected to the support frame, and the piston of the first cylinder is connected to the vertical moving slider.

[0008] Furthermore, the horizontal moving mechanism is a second cylinder extending in the left-right direction, the cylinder barrel of the second cylinder is rotatably connected to the support plate, and the piston of the second cylinder is fixedly connected to the clamping plate.

[0009] Furthermore, the inner sides of both left and right clamping discs are fixedly provided with locking blocks, and the left and right sides of the coil are provided with locking slots that cooperate with the locking blocks.

[0010] Furthermore, a rotary motor is installed on the top of one of the support plates, and a transmission wheel is installed on the cylinder of the second cylinder on the corresponding side. The rotary motor and the transmission wheel are connected in a transmission connection.

[0011] Furthermore, a pad rod is provided on the lower side of the coil. Two pad rods extend in the left-right direction and are arranged in parallel. A set of insertion holes is provided on the support frame at the position corresponding to the two pad rods. The set of insertion holes consists of multiple insertion holes arranged at intervals in the up-down direction. The two ends of the pad rod are movably inserted into the corresponding insertion holes.

[0012] Furthermore, a positioning block is fixed to the bottom of one of the pads, and the positioning block is provided with a positioning groove.

[0013] Furthermore, the lower side of the pad rod is provided with a horizontal slide rail, which extends in the left and right direction and is fixed on the support frame. A horizontal sliding block is provided on the horizontal slide rail and is slidably connected to it. A moving block is fixed on the horizontal sliding block and a moving groove is provided on the moving block.

[0014] Furthermore, the horizontally moving slider has a power unit for driving the horizontally moving slider to move on the horizontal slide rail.

[0015] Furthermore, the horizontal slide rail is arranged on the side close to the positioning groove.

[0016] The beneficial effects of this invention are: (1) The present invention can adjust the height of the support plate at any time through the vertical moving mechanism, thereby adjusting the height of the cable reel when laying the cable, which helps to reduce the height difference between the cable and the terrain when laying the cable and prevent the cable from bending due to the height difference when laying the cable.

[0017] (2) The present invention uses a horizontal moving mechanism to drive the two clamping plates on the left and right sides to clamp and fix the spool. The operation is simple and quick, and it can adapt to spools of different lengths.

[0018] (3) The present invention also includes a height-adjustable support rod below the spool. After raising the height of the spool, the height of the support rod can also be raised, so that the support rod is always in contact with the bottom of the spool and provides support for the spool.

[0019] (4) The present invention also designs a positioning block and a positioning groove, a moving block and a moving groove. The positioning block and the positioning groove can maintain the stable position of the wire during the wire laying process and prevent the wire from deviating from the predetermined track due to sudden changes in tension. The moving block and the moving groove can finely adjust the position of the cable when needed during the wire laying process to ensure that the cable remains stable during the wire laying process.

[0021] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Example 1

[0023] like Figures 1 to 4 As shown, this embodiment provides a cable laying device, including a cable reel 2 and support frames 1 located on both sides of the cable reel. The left and right ends of the cable reel 2 are respectively mounted on the support frames 1 through position adjustment mechanisms.

[0024] Specifically, the position adjustment structure includes a vertical guide rail 4 and a vertical moving mechanism mounted on the support frame 1. The vertical guide rail extends in the vertical direction and is fixedly connected to the support frame 1. A vertical moving slider 4 is provided on the vertical guide rail 4 and is slidably connected thereto. The vertical moving mechanism is a first cylinder 3 extending in the vertical direction. The cylinder barrel of the first cylinder 3 is fixedly connected to the support frame 1, and the piston rod end of the first cylinder 3 is fixedly connected to the vertical moving slider 4.

[0025] The inner side of the vertically moving slider 4 is fixed with a support plate 6, and the support plate 6 is equipped with a horizontal moving mechanism. The horizontal moving mechanism is a second cylinder 7 extending in the left-right direction. The cylinder part of the second cylinder 7 is rotatably connected to the support plate 6, and the piston rod end of the second cylinder 7 is fixed with a clamping plate 8.

[0026] Two clamping discs 8 form a clamping mechanism for the wire reel 2, and each of the two clamping discs 8 has a locking block 9 fixedly installed on its inner side. The left and right sides of the wire reel have locking grooves 10 that cooperate with the locking blocks 9. The diameter of the locking groove 10 is slightly larger than the diameter of the locking block 9 so that the locking block 9 can be smoothly inserted into the locking groove 10.

[0027] During operation, the piston rod of the second cylinder 7 extends and retracts, which can move the two clamping plates 8. The clamping plates 8 can clamp the two sides of the coil 2, which is beneficial for fixing the inserted coil and can accommodate coils of different lengths.

[0028] A rotary motor 11 is mounted on the top of the left support plate, and a transmission wheel is mounted on the cylinder of the second cylinder on the left. The rotary motor 11 and the transmission wheel are driven by a belt to rotate the left clamping plate. In this embodiment, the piston rod of the second cylinder 7 is a splined shaft structure, which does not affect the horizontal extension and retraction of the piston rod, and also ensures that the power of the rotary motor 11 can be smoothly transmitted to the clamping plate.

[0029] The specific working process of this invention is as follows: First, retract the piston rod of the second cylinder 7 into the cylinder. Then, the two clamping plates 8 move in opposite directions and the distance between them increases. At this time, place the cable reel 2 between the two clamping plates 8. Then, the bottom of the cable reel 2 contacts the pad rod 13, which provides support for it. The distance between the two clamping plates 8 can be adjusted by the second cylinder 7, which is beneficial for accommodating cable reels 2 of different lengths.

[0030] Then, the piston rod of the second cylinder 7 extends and drives the clamping plate 8 to move. Then, the locking block 9 on the clamping plate 8 enters the inside of the locking groove 10 on the clamping plate 8, thereby clamping the two sides of the coil 2 and fixing the inserted coil 2.

[0031] Once the above preparations are completed, the cable can be laid out. When laying out the cable, start the rotary motor 11. The rotary motor 11 drives the second cylinder 7 and the clamping plate 8 to rotate via belt drive. Since the cable reel 2 is fixed between the two clamping plates 8, the rotation of the clamping plates 8 drives the cable reel 2 to rotate. The speed of the cable reel 2 is reduced by the reducer. Then, when the cable reel 2 rotates, the cable is laid out.

[0032] During operation, if the height of the cable reel 2 needs to be adjusted, the height of the support plate 6 is adjusted by the first cylinder 3, thereby adjusting the height of the cable reel 2 when laying the cable. This helps to reduce the height difference between the cable and the ground when laying the cable and prevents the cable from bending due to the height difference when it is laid out. Example 2

[0033] like Figures 1 to 2 As shown, in this embodiment, based on Embodiment 1, a pad rod 13 is further provided on the lower side of the coil 2. Two pad rods 13 extend in the left-right direction and are arranged in parallel. A set of insertion holes is provided on the support frame 1 at positions corresponding to the two pad rods 13. The set of insertion holes consists of multiple insertion holes 14 arranged at intervals in the up-down direction. The two ends of the pad rod 13 are movably inserted into the corresponding insertion holes.

[0034] Specifically, a pin 15 is provided in the socket 14, which can penetrate into the interior of the pad rod 13 and limit the pad rod 13.

[0035] After raising the height of the coil 2, the pin 15 can be removed from the pad 13, and then the height of the pad 13 can be manually raised so that the pad 13 is always in contact with the bottom of the coil 2. After adjusting the height of the pad 13, the pin 15 can be inserted into the pad 13 through the insertion hole 14 to fix the pad 13.

[0036] To ensure smooth rotation of the coil 2, the pad rod 13 is made of a round shaft and can rotate with the pin. Example 3

[0037] like Figure 1 As shown, in this embodiment, based on embodiment two, a positioning block 17 is fixed at the bottom of the front pad rod, and a positioning groove is provided on the positioning block 17.

[0038] A horizontal slide rail 18 is also provided on the lower side of the pad rod 13. The horizontal slide rail 18 is arranged on the side close to the positioning groove. The horizontal slide rail 18 extends in the left and right direction and is fixed on the support frame 1. A horizontal moving slider 19 is provided on the horizontal slide rail 18 and is slidably connected to it. A moving block 20 is fixed on the horizontal moving slider 16, and a moving groove 21 is provided on the moving block 20.

[0039] In this embodiment, the horizontal slide rail 18 is an electromagnetic slide rail, and the horizontal moving slider 19 is an electromagnetic slider, which enables the electromagnetic slider to move autonomously on the electromagnetic slide rail.

[0040] The positioning block 17 and the positioning groove are used to maintain the stable position of the cable during the laying process, preventing the cable from deviating from the predetermined track due to sudden changes in tension. The moving block 20 and the moving groove 21 are used to fine-tune the position of the cable when needed during the laying process, ensuring that the cable remains stable throughout the laying process. The positioning block 17 mainly maintains the stability of the cable during laying, while the moving block 20 is responsible for fine-tuning the position of the cable during laying.

[0041] During cable laying, one end of the cable is passed sequentially through the positioning groove of the positioning block 17 and the moving groove 21 of the moving block 20. Then, under the action of the counterweight, one end of the cable is pulled out partially. Afterward, the rotary motor 1 is started to drive the cable reel 2 to rotate, and the cable is released when the cable reel 2 rotates.

[0042] When fine-tuning of the cable is required, the horizontal sliding slider 19 can be moved on the horizontal slide rail 18, and then the moving block 20 moves with the horizontal sliding slider 19 to fine-tune the cable. Example 4

[0043] This embodiment, based on embodiment three, adds an automated control system and a tension sensor. The tension sensor is installed at the end of the cable and is connected to the signal input terminal of the automated control system. The signal output terminal of the automated control system is connected to the rotary motor 11 for control.

[0044] During the cable laying process, when the tension sensor detects a sudden increase in cable tension, the automated control system immediately increases the rotation speed of the rotary motor 11, causing the length of the laid-out cable to increase rapidly. This compensates for potential cable breakage due to increased tension, ensuring timely replenishment when stress changes occur in the cable and preventing cable breakage.

[0045] The automated control system and tension sensor involved in this embodiment are existing technologies, and their specific solutions will not be described in detail.

[0046] The above embodiments are only used to illustrate and not limit the technical solutions of the present invention.
