Description

Technical Field

[0001] This invention relates to the field of power construction technology, and in particular to a wire-laying device for power supply construction. Background Technology

[0002] During the construction of power supply systems, it is necessary to lay cables from cable reels. To reduce the labor intensity of cable laying, cable conveyors are now often used as an auxiliary tool.

[0003] Because the cable on the cable reel is wound back and forth during production, with the conveying force of the cable conveyor remaining constant, as the cable exits and approaches the sides of the cable reel, the lateral force exerted on the cable conveyor increases, causing the cable to slip within the conveyor and affecting the cable laying efficiency. Furthermore, since different manufacturers use cable reels with varying widths, supports with different spacings are required for on-site fixation. When the cable conveyor is used in conjunction with the reel, its output performance varies depending on its installation location, making it impossible to guarantee a consistent laying effect during construction. Summary of the Invention

[0004] To address the shortcomings of the prior art, this invention provides a cable laying device for power supply construction, which ensures that the cable laying direction is always consistent with the cable reel outlet, avoids cable slippage, ensures laying efficiency, and guarantees consistent laying effect for different cable reels.

[0005] The technical solution of this invention is as follows: a cable reeling and laying device for power supply construction, comprising a first moving platform, a second moving platform, a cable support assembly, and a cable conveying assembly. The cable support assembly includes two support frames for supporting cable reels. The lower ends of the support frames are mounted parallel to the surface of the first moving platform via a spacing adjustment assembly, enabling the installation of cable reels of different sizes. The front end of the second moving platform is detachably connected to the rear end of the first moving platform along the cable reel's output direction. A first slide rail perpendicular to the cable reel's output direction is mounted on the surface of the second moving platform. Two positioning blocks corresponding to the positions of the support frames are slidably connected on the first slide rail. The cable conveying assembly is mounted on the first slide rail between the positioning blocks via a translation assembly, enabling the cable conveying assembly to reciprocate between the positioning blocks. The positioning blocks correspond to the positions of the support frames. The cable conveying assembly reciprocates between the positioning blocks via the translation assembly, thereby ensuring that the cable is always output horizontally when the cable is laid out by the cable conveying assembly, thus avoiding cable slippage and ensuring the laying efficiency of the device.

[0006] The spacing adjustment assembly includes a guide rod and a bidirectional lead screw. The guide rod is mounted on the first movable platform perpendicular to the cable reel's output direction. The two ends of the bidirectional lead screw are rotatably connected to both sides of the first movable platform via bearing seats. The bottom of the support frame is slidably connected to the guide rod via a sliding groove. The threads on both sides of the bidirectional lead screw pass through threaded holes at the lower ends of the two support frames, enabling the support frames to move towards each other. The spacing between the two support frames is adjusted via the bidirectional lead screw, accommodating cable reels of different widths. The positioning blocks are then adjusted to correspond to the positions of the support frames, ensuring consistent cable delivery even when different sizes of cable reels are installed on-site.

[0007] The cable conveying assembly includes a conveying platform, a drive roller assembly, and a driven roller assembly. The bottom of the conveying platform is slidably connected to a first slide rail via a slider. The drive roller assembly and the driven roller assembly are installed side by side on the conveying platform, forming a cable channel between them for the cable to pass through.

[0008] The translation assembly includes a translation rack, a drive motor, and a reversing gear set. The two ends of the translation rack are fixedly connected to both sides of the second moving platform via support rods. The reversing gear set includes a drive shaft, gear one, gear two, reversing bevel teeth, a U-shaped gear frame, and two forward ratchet wheels. The U-shaped gear frame and the drive motor are fixedly installed at the bottom of the conveying platform. The output end of the drive motor passes through a transverse rotating shaft into the closed end of the U-shaped gear frame and connects with the reversing bevel teeth. The drive shaft is rotatably connected to the two ends of the open end of the U-shaped gear frame and extends upward through the conveying platform. The two ratchet wheels are respectively fixedly installed at both ends of the drive shaft inside the U-shaped gear frame. Gear one and gear two are respectively installed on the outside of the ratchet wheels, and the reversing bevel teeth mesh with gear one and gear two respectively. A drive sprocket is installed on the drive shaft extending through the conveying platform. The drive sprocket meshes with the driven sprocket installed on the drive roller assembly rotating shaft in sequence via a chain. A drive wheel is installed on the transverse rotating shaft outside the closed end of the U-shaped gear frame, and the drive wheel meshes with the translation rack. Due to the presence of two forward ratchet wheels, when the drive motor rotates forward, the drive teeth drive the conveyor platform to move along the first direction of the translation rack. At this time, the reversing bevel teeth drive gear one and gear two to rotate forward and reverse respectively. Gear one, rotating forward, drives the drive sprocket to rotate forward via the ratchet, while gear two, rotating in the opposite direction, cannot be linked to the ratchet, thus realizing the forward rotation of the drive roller group for line feeding. When the bottom slider of the conveyor platform contacts the positioning block on one side, the drive motor reverses. At this time, the drive teeth drive the conveyor platform to move along the second direction of the translation rack, while gear one and gear two become reverse and forward respectively. Gear one, rotating in the reverse direction, cannot be linked to the ratchet, while gear two, rotating forward, drives the drive sprocket to rotate forward via the ratchet, maintaining the line feeding action of the drive roller group.

[0009] A torque sensor is installed on the conveying platform. The torque sensor is fixed to the bottom of the conveying platform by a bracket. Both ends of the torque sensor are connected to the transverse rotating shaft and the output end of the drive motor via couplings, respectively. The torque sensor is electrically connected to the control module that controls the drive motor. By sensing the operating status of the motor through the torque sensor, the smooth laying of the cable during the cable conveying process is monitored. If any cable diagonal pulling or twisting occurs during the laying process, timely judgment and feedback are provided.

[0010] The positioning block is equipped with a pressure sensor, a laser positioning pen, and a locking bolt. The pressure sensor is installed on the inner side of the positioning block and is electrically connected to the control module that controls the drive motor. It is used to sense the pressure of the bottom slider of the conveying platform contacting the positioning block and control the operation of the drive motor. The laser pen is installed at the front end of the positioning block. The laser emitted by the laser pen passes through the laser hole opened on the surface of the support frame. The locking bolt passes through the threaded hole on the surface of the positioning block and locks into contact with the surface of the first slide rail.

[0011] The driven roller assembly is movably mounted on the conveying platform via a size adjustment component. The size adjustment component includes an adjustment plate, a fixed plate, an adjustment screw, and a locking nut. A second slide rail perpendicular to the cable channel is mounted on the surface of the conveying platform. The bottom of the adjustment plate is slidably connected to the second slide rail via a groove. The driven roller assembly is rotatably mounted on the adjustment plate. The fixed plate is fixed to the side of the conveying platform away from the drive roller assembly. One end of the adjustment screw is rotatably connected to the outside of the adjustment plate via a bearing, and the other end of the adjustment screw passes through a threaded hole on the fixed plate and is engaged with the locking nut. The size adjustment component can adjust the gap between the driven roller assembly and the drive roller assembly, thereby adapting to cables of different sizes.

[0012] The second moving stage has a plug at its front end, and the first moving stage has a slot at its rear end for inserting the plug. A limiting pin is provided on the first moving stage, passing sequentially through the slot and a limiting hole on the surface of the plug to lock the plug within the slot. This detachable connection between the first and second moving stages effectively improves the portability of the entire device and solves the transportation difficulties caused by its large size.

[0013] Both the first and second movable platforms are equipped with casters at their bottoms. The rear end of the first movable platform has a U-shaped bracket, with its open ends rotatably connected to the sides of the first movable platform via pivots. Limiting protrusions are installed on both sides of the first movable platform, and grooves that mate with the limiting protrusions are formed on the vertical ends of the U-shaped bracket. These grooves engage with the limiting protrusions, providing vertical support for the U-shaped bracket. The U-shaped bracket enhances support when the device is assembled, allowing the connection point between the two movable platforms to bear weight and ensuring the stability of the device during use.

[0014] The beneficial effects of this invention are as follows:

[0015] In this solution, by installing a translation component, the conveying platform of the cable conveying component reciprocates between two positioning blocks, ensuring that the cable is always aligned with the exit direction of the cable reel when being laid out by the cable conveying component, thereby preventing cable slippage and ensuring the laying efficiency of the device; and by ensuring that the positioning blocks and the support frame always slide in correspondence, the laying effect remains consistent for cable reels of different sizes installed on site.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative effort should all fall within the protection scope of this invention.

[0025] like Figure 1 and Figure 2As shown, this invention provides a cable winding and unwinding device for power supply construction, including a first moving platform 1, a second moving platform 2, a cable support assembly 3, and a cable conveying assembly 4. The first moving platform 1 is equipped with a spacing adjustment assembly, which includes a guide rod 33 and a bidirectional lead screw 32. The guide rod 33 is mounted on the first moving platform 1 perpendicular to the cable reel 5's outgoing direction. The two ends of the bidirectional lead screw 32 are rotatably connected to both sides of the first moving platform 1 via bearing seats 34. The cable support assembly 3 includes two support frames 31 for supporting the cable reel 5. The bottom of each support frame 31 is slidably connected to the guide rod 33 via a sliding groove. The threads on both sides of the bidirectional lead screw 32 pass through threaded holes at the lower ends of the two support frames 31, enabling the support frames 31 to move towards each other. The spacing between the two support frames 31 is adjusted by the bidirectional lead screw 32, allowing for the installation of cable reels 5 of different widths. A plug 21 is installed at the front end of the second moving platform 2, and a plug 21 is provided at the rear end of the first moving platform 1 for insertion. The first movable stage 1 is provided with a limiting pin 12, which passes through the limiting hole 22 opened on the surface of the slot 11 and the plug 21 in sequence, realizing the detachable connection between the first movable stage 1 and the second movable stage 2, effectively improving the portability of the whole device; the surface of the second movable stage 2 is equipped with a first slide rail 23 perpendicular to the cable reel 5 outlet direction, and two positioning blocks 8 are slidably connected on the first slide rail 23. The positioning block 8 is provided with a laser positioning pen 9 and a locking bolt 81. The laser pen 9 is installed at the front end of the positioning block 8, and the laser emitted by the laser pen 9 passes through the laser hole 311 opened on the surface of the support frame 31. The locking bolt 81 passes through the threaded hole on the surface of the positioning block 8 and locks into contact with the surface of the first slide rail 23, thereby realizing the correspondence between the positioning block 8 and the support frame 31. The cable conveying component 4 is installed on the first slide rail 23 between the positioning blocks 8 via the translation component 43, realizing the reciprocating movement of the cable conveying component 4 between the positioning blocks 8. This device uses the positioning block 8 to correspond with the support frame 31. The cable conveying component 4 moves back and forth between the positioning blocks 8 via the translation component 43, thereby ensuring that the cable is always output horizontally when it is being laid out by the cable conveying component 4, thus avoiding cable slippage and ensuring the laying efficiency of the device.

[0026] The cable conveying assembly 4 includes a conveying platform 44, a drive roller assembly 41, and a driven roller assembly 42. The bottom of the conveying platform 44 is slidably connected to the first slide rail 23 via a slider 442. The drive roller assembly 41 and the driven roller assembly 42 are installed side by side on the conveying platform 44, forming a cable channel between the drive roller assembly 41 and the driven roller assembly 42 for the cable to pass through.

[0027] The translation component 43 includes a translation rack 431, a drive motor 432, and a reversing gear set 433. The translation rack 431 is fixedly connected to both sides of the second moving platform 2 via support rods 4311. The reversing gear set 433 includes a drive shaft 4332, a first gear 4331, a second gear 4333, a reversing bevel gear 4335, a U-shaped gear carrier 4334, and two forward ratchet wheels 4336. The U-shaped gear carrier 4334 and the drive motor 432 are fixedly installed at the bottom of the conveying platform 44. The output end of the drive motor 432 passes through a transverse rotating shaft into the closed end of the U-shaped gear carrier 4334 and connects to the reversing bevel gear 4335. The drive shaft 4332 is connected to the open end of the U-shaped gear carrier 4334. The two ends are rotatably connected and extend upward through the conveying platform 44. Two ratchet wheels 4336 are respectively fixedly installed at both ends of the drive shaft 4332 inside the U-shaped gear frame 4334. Gear 1 4331 and gear 2 4333 are respectively installed on the outside of the two ratchet wheels 4336. The reversing bevel teeth 4335 mesh with gear 1 4331 and gear 2 4333 respectively. A drive sprocket 46 is installed on the drive shaft 4332 extending through the conveying platform 44. The drive sprocket 46 is connected to the driven sprocket 47 installed on the drive roller assembly 41 shaft in sequence through the chain 48. A drive wheel 435 is installed on the transverse rotating shaft outside the closed end of the U-shaped gear frame 4334. The drive wheel 435 meshes with the translation rack 431. Due to the presence of two forward ratchet gears 4336, when the drive motor 432 rotates forward, the drive gear 435 drives the conveyor platform 44 to move along the first direction of the translation rack 431. At this time, the reversing bevel gear 4335 drives gear one 4331 and gear two 4333 to rotate forward and reverse respectively. The forward-rotating gear one 4331 drives the drive sprocket 46 to rotate forward via the ratchet gear 4336, while gear two 4333 cannot be linked with the ratchet gear 4336 because of its opposite rotation direction, thus realizing the forward rotation of the drive roller assembly 41. When the bottom slider 442 of the conveying platform 44 contacts the positioning block 8 on one side, the drive motor 432 reverses. At this time, the drive gear 435 drives the conveying platform 44 to move along the second direction of the translation rack 431, while gear one 4331 and gear two 4333 turn in reverse and forward respectively. The reverse rotating gear one 4331 cannot be linked with the ratchet 4336, and the forward rotating gear two 4333 drives the drive sprocket 46 to rotate forward through the ratchet 4336, maintaining the line feeding action of the drive roller group 41.

[0028] A torque sensor 434 is installed on the conveying platform 44. The torque sensor 434 is fixed to the bottom of the conveying platform 44 by a bracket. The two ends of the torque sensor 434 are connected to the horizontal rotating shaft and the output end of the drive motor 432 respectively via a coupling 436. The torque sensor 434 is electrically connected to the control module that controls the drive motor 432. A pressure sensor 10 is installed inside the positioning block 8. The pressure sensor 10 is electrically connected to the control module that controls the drive motor 432. It is used to sense the pressure of the bottom slider 442 of the conveying platform 44 contacting the positioning block 8 and control the operation of the drive motor 432. The control module can set pressure threshold and torque threshold. When the value detected by the torque sensor 434 exceeds the torque threshold, and at the same time the pressure sensor 10 senses that the squeezing force of the bottom slider 442 of the conveying platform exceeds the pressure threshold, the drive motor 432 is controlled to switch between forward and reverse rotation. When the value detected by the torque sensor 434 exceeds the torque threshold and continues to increase, and the pressure sensor 10 does not sense it, it is determined that there is a phenomenon of cable skewing or twisting during the cable laying. The drive motor 432 is stopped in time to prevent damage to the drive motor 432.

[0029] The driven roller assembly 42 is movably mounted on the conveying platform 44 via a size adjustment assembly 45. The size adjustment assembly 45 includes an adjustment plate 454, a fixed plate 451, an adjustment screw 453, and a locking nut 452. A second slide rail 441 perpendicular to the cable channel is mounted on the surface of the conveying platform 44. The bottom of the adjustment plate 454 is slidably connected to the second slide rail 441 via a groove. The driven roller assembly 42 is rotatably mounted on the adjustment plate 454. The fixed plate 451 is fixed to the side of the conveying platform 44 away from the drive roller assembly 41. One end of the adjustment screw 453 is rotatably connected to the outside of the adjustment plate 454 via a bearing, and the other end of the adjustment screw 453 passes through a threaded hole on the fixed plate 451 and engages with the locking nut 452. The size adjustment assembly 45 can adjust the gap between the driven roller assembly 42 and the drive roller assembly 41, thereby adapting to cables of different sizes.

[0030] Both the first movable platform 1 and the second movable platform 2 are equipped with casters 6 at their bottoms. The rear end of the first movable platform 1 is provided with a U-shaped bracket 7. The two ends of the open side of the U-shaped bracket 7 are rotatably connected to the two sides of the first movable platform 1 via pivots. Limiting protrusions 13 are installed on both sides of the first movable platform 1. A groove 71 is provided on the vertical side of the U-shaped bracket 7 to cooperate with the limiting protrusion 13. The groove 71 engages with the limiting protrusion 13, providing vertical support for the U-shaped bracket 7. The U-shaped bracket 7 provides enhanced support when the device is assembled, allowing the connection between the two movable platforms to bear weight and ensuring the stability of the device during use. Preferably, the outer ends of the bidirectional lead screw 32 and the adjusting lead screw 453 are each equipped with a crank handle. To ensure the stability of each component during movement, there are two of each of the first slide rail 23, the second slide rail 441, and the guide rod 33.

[0031] In use, the first moving platform 1 and the second moving platform 2 are pushed to the construction position and spliced ​​together. According to the width of the cable reel 5, the bidirectional screw 32 is rotated to adjust the spacing between the support frames 31. The cable reel 5 is rotated and installed on the upper end of the support frame 31 via the rotating shaft. The position of the positioning block 8 is adjusted so that the laser emitted by the laser pen 9 on the positioning block 8 is aligned with the laser hole 311 of the support frame 31, thus completing the alignment of the positioning block 8 and the support frame 31. The drive motor 432 is controlled to move the conveying platform 44 to be aligned with the cable reel 5's outlet position, allowing the cable to pass through the cable channel of the cable conveying assembly 4. The adjusting screw 453 is rotated to make the driven roller group 42 and the drive roller group 41 in close contact with the cable. The drive motor 432 is turned on to perform the cable feeding operation. At this time, the drive gear 435 drives the conveying platform 44 to move back and forth between the positioning blocks 8, achieving stable cable feeding.
