Description

Technical Field

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

[0002] Cable laying refers to the construction process of safely and orderly arranging power cables, communication cables, or other types of cables in a predetermined path by manual or mechanical means according to design requirements. Its core purpose is to ensure that the cables are safe and reliable when transmitting electrical energy or signals, are easy to maintain, and meet the requirements of electrical performance, mechanical strength, and environmental protection.

[0003] When laying cables, the cable is usually unwound from the unwinding roller and pulled by traction force to lay the cable. However, in the existing technology, when the cable laying line is not a straight line, human error may cause some places to be slightly crooked. At this time, the user needs to adjust the direction of the trolley, which consumes a lot of the user's physical strength. Utility Model Content

[0026] Reference Figures 1-4This utility model provides a technical solution: a cable laying device, including a base plate 1 and an unwinding roller 2, on which a cable is wound and sleeved. A cable laying mechanism is provided on the base plate 1, including a lifting box 301 and a sliding rod 303. The lifting box 301 is located on the top of the base plate 1, and a vertically penetrating sliding groove 302 is opened on the lifting box 301. The sliding rod 303 is fixed to the inner wall of the lifting box 301, and a movable box 304 is slidably sleeved on the surface of the sliding rod 303. A slide frame 305 is fixed on the top of the movable box 304. A reciprocating screw 306 is rotatably arranged on the inner wall of the lifting box 301, and the movable box 304 is threaded onto the surface of the reciprocating screw 306. A first motor 307 is fixed to the right side of the lifting box 301 by bolts and a mounting plate. The output end of the first motor 307 is fixedly connected to the reciprocating screw 306 through a coupling. The top of the base plate 1 is open to the cable laying mechanism. A hydraulic rod 308 is fixedly mounted on a bolt and mounting base. The output end of the hydraulic rod 308 is fixedly connected to the bottom of the lifting box 301. By setting up a cable laying mechanism, the user puts the cable inside the slide 305 and moves the base plate 1 by means of rollers and handrails. At the same time, the unwinding roller 2 is activated and a traction force is applied to the cable to unwind it, thereby laying the cable. When the laying direction of the cable needs to be changed, the first motor 307 is activated to drive the reciprocating screw 306 to rotate. Through the threaded connection between the reciprocating screw 306 and the moving box 304, and the limiting cooperation of the slide 303, the moving box 304 drives the slide 305 to slide until it reaches the preset position and then the first motor 307 is turned off. In another embodiment, the reciprocating screw 306 can be replaced with a unidirectional screw and the first motor 307 can be replaced with a reciprocating stepper motor.

[0027] Reference Figures 1-4A straightening mechanism is provided on the top of the base plate 1. The straightening mechanism includes a fixed seat 401, which is fixedly installed on the top of the base plate 1. Several fixed seats 401 are provided. A fixed ring 402 is fixedly installed inside the fixed seat 401. A rotating ring 403 is rotatably installed inside the fixed seat 401. The fixed ring 402 and the rotating ring 403 are coaxially arranged. Several limiting grooves 404 are opened on the side of the fixed ring 402 near the rotating ring 403. A slider 405 is slidably installed inside the limiting groove 404. A connecting rod 406 is fixed on the slider 405. At the other end, a straightening block 407 is fixedly provided. Several rollers are rotatably arranged on the inner wall of the straightening block 407 to reduce friction with the cable. Several arc-shaped grooves 408 are opened on the side of the rotating ring 403 near the fixed ring 402. The number of arc-shaped grooves 408 is the same as the number of limiting grooves 404. A sliding shaft 409 is slidably sleeved inside the arc-shaped groove 408. The sliding shaft 409 and the slider 405 are fixedly connected. A gear ring 410 is coaxially fixed on the surface of several rotating rings 403. A gear 411 is rotatably arranged inside the fixed base 401. The gear ring 410 and the gear 411 are rotatably arranged inside the fixed base 401. A transmission rod 412 is coaxially fixed between several gear rings 410. A second motor 413 is fixed to the top of the base plate 1 by bolts and a mounting plate. The output end of the second motor 413 is fixedly connected to one of the gears 411 through a coupling. By setting a straightening mechanism, the user passes the cable through several fixed rings 402 and rotating rings 403, starts the second motor 413, and drives one of the gears 411 to rotate. Through the cooperation of the transmission rod 412, several gears 411 rotate simultaneously. Through the meshing of the gears 411 and the gear rings 410... The connection causes the gear ring 410 to drive the rotating ring 403 to rotate, which causes the inner wall of the arc groove 408 to squeeze the sliding shaft 409. Under the limiting cooperation of the limiting groove 404, the sliding shaft 409 drives the limiting block, connecting rod 406 and straightening block 407 to move radially towards the center of the fixed ring 402 until all the rollers on the straightening blocks 407 are in contact with the cable. During the process of being pulled and unwound, the cable is first straightened by several rows of straightening blocks 407 to avoid the cable being wrapped on the unwinding roller 2 for a long time, which would cause the cable to be excessively bent.

[0028] Specifically, the working process or principle of this cable laying device is as follows: During use, the user passes the cable through several fixed rings 402, rotating rings 403, and slide 305. The second motor 413 is started, driving one of the gears 411 to rotate. Through the engagement of the transmission rod 412, several gears 411 rotate simultaneously. The meshing connection between the gears 411 and the gear ring 410 causes the gear ring 410 to drive the rotating ring 403 to rotate. This causes the inner wall of the arc-shaped groove 408 to press against the slide shaft 409. Under the limiting engagement of the limiting groove 404, the slide shaft 409 drives the limiting block and connecting rod 405. Simultaneously, the straightening block 407 and the straightening block 407 move radially towards the center of the fixed ring 402 until all the rollers on the straightening block 407 are in contact with the cable. During the unwinding process, the cable is first straightened by several rows of straightening blocks 407 to prevent the cable from being wrapped around the unwinding roller 2 for a long time, which would cause the cable to be excessively bent. When the laying direction of the cable needs to be changed, the first motor 307 is started to drive the reciprocating screw 306 to rotate. Through the threaded connection between the reciprocating screw 306 and the moving box 304, and the limiting cooperation of the slide rod 303, the moving box 304 drives the slide 305 to slide.
