Description

Technical Field

[0001] The utility model belongs to the field of cable laying, and in particular relates to a cable traction device for cable laying. Background Art

[0002] The traction device of the prior art can only release the cable wrapped on the surface of the coil by rotating it. The cable is accumulated on the ground below the coil due to gravity and the friction of the ground. Manual pulling is still required to pull the accumulated cable from the ground. The cable traction is not convenient enough and still requires manual participation. When the cable is pulled and released, the friction of the remaining devices will aggravate the wear of the cable surface, and even cause the internal copper wire to leak out due to wear, causing damage to the cable.

[0003] The Chinese patent with the publication number CN220306852U discloses a cable traction device for cable laying; it includes a movable trolley, an electric control box is arranged on the right side of the top of the movable trolley, a traction mechanism for retracting and releasing the cable is arranged on the left side of the electric control box, the traction mechanism includes two vertical and spaced reel brackets, a reel for winding the cable can be rotatably mounted between the two reel brackets, a first motor is arranged on the outer side of the reel bracket, the first motor is connected to the reel in a transmission manner, a vertically arranged retractable support frame is arranged on the left side of the top of the movable trolley, a vertically arranged rotating shaft can be rotatably mounted on the top of the retractable support frame, a tightening wheel bracket is fixed at the bottom end of the rotating shaft, and a tightening wheel can be rotatably mounted on the tightening wheel bracket; a guide rope mechanism for adjusting the cable winding angle is arranged between the retractable support frame and the reel; and a fixing mechanism for fixing the movable trolley is arranged at the four corners of the movable trolley. The utility model has a simple structure, can facilitate cable laying, and improve work efficiency.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cable traction device for cable laying, thereby solving the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] A cable traction device for cable laying, comprising: a placement plate, the top surface of the placement plate is fixedly connected to a bracket in an axisymmetric manner, the surfaces of the placement plate and the bracket are both provided with rotation holes, a rotating rod is rotatably connected inside the rotation hole, a pay-off wheel is sleeved on the surface of the rotating rod, a driving assembly is fixedly connected to the bottom surface of the rotating rod, and a protection assembly is fixedly connected to the side surface of the placement plate;

[0008] The driving assembly comprises a device box fixedly connected to the top surface of the placement plate, a driving motor is sleeved inside the device box, and a rotating structure is fixedly connected to the output end of the driving motor.

[0009] Optionally, the rotating structure includes a rotating gear fixedly connected to the output end of the driving motor, and driven gears are meshed on both sides of the rotating gear, and the driven gears are fixedly connected to the bottom end of the rotating rod; when the rotating gear rotates, it will drive the two driven gears meshed on both sides to rotate in opposite directions, so that the top surface of the pay-off wheel connected to the rotating rod rotates synchronously, thereby pushing and pulling the cable placed between the two pay-off wheels.

[0010] Optionally, the bottom surface of the driven gear is fixedly connected with a connecting block, the bottom end of the connecting block is sleeved with a bearing for rotation, and the bearing is axially symmetrically fixedly connected to the top surface of the equipment box. When the driven gear rotates, it rotates inside the bearing through the bottom connecting block, so that the driven gear rotates more smoothly and avoids affecting the traction effect of the upper pay-off wheel.

[0011] Optionally, the protection component includes a buffer structure fixedly connected to the side of the placement plate, one end of the buffer structure is fixedly connected to a rotating groove, and the rotating groove is rotatably connected to a roller through jacks opened on both sides. When the placement plate of the cable moves outward, it rubs the roller to cause it to rotate in the rotating groove, thereby converting the sliding friction generated by the direct contact between the cable and the placement plate into rolling friction after contact with the roller, thereby greatly reducing friction and avoiding wear on the cable surface.

[0012] Optionally, the buffer structure includes a sleeve fixedly connected to the side of the placement plate, the interior of the sleeve is slidably connected to a slide rod, and the side of the sleeve is fixedly connected to the slide rod via a spring. When the cable is placed on the surface of the roller, the rotating groove drives the spring on the side of the slide rod to buffer the squeezing force during the rebound of the spring to prevent the cable from being crushed on the roller surface.

[0013] Optionally, the bottom surface of the placement plate is axially symmetrically fixedly connected to the side plate, the bottom surface of the side plate is fixedly connected to the bottom plate, the bottom surface of the bottom plate is axially symmetrically fixedly connected to the universal wheel, and a brake mechanism is provided inside the universal wheel. The brake structure can effectively start and stop the universal wheel, so that the overall traction device can be stably placed in a fixed location.

[0014] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0015] 1. Through the setting of the driving component, the driving motor drives the rotating gear fixed on the top of the output end to rotate, so that the driven gears meshing on both sides rotate in opposite directions, and drive the pay-off wheel fixed on the top surface by the rotating rod to rotate synchronously in opposite directions, and push the cable placed between the two pay-off wheels, so as to achieve the effect of directly pulling the cable out of the coil, without the need for manual re-pulling of the cable accumulated on the ground, thereby improving the convenience of operation.

[0016] 2. Through the setting of the protection component, the cable pulled out by the pay-off wheel moves in accordance with the roller connected to the rotation inside the trough to avoid wear of the cable surface caused by sliding friction. At the same time, the cable with higher weight will push the sliding rod fixed on the back of the trough to move. The spring will be compressed when the sliding rod moves. During the contraction of the spring, the squeezing of the cable on the roller will be buffered to avoid compression of the cable surface, thereby protecting the moving cable and avoiding wear or compression.

DETAILED DESCRIPTION

[0027] The utility model is now described in further detail with reference to the accompanying drawings.

[0028] See also Figure 1-4 As shown, in this embodiment, a cable traction device for cable laying is provided, including: a placement plate 1, the top surface of the placement plate 1 is axially symmetrically fixedly connected with a bracket 2, the surfaces of the placement plate 1 and the bracket 2 are provided with rotating holes, the inside of the rotating hole is rotatably connected with a rotating rod 3, the surface of the rotating rod 3 is sleeved with a pay-off wheel 4, the bottom surface of the rotating rod 3 is fixedly connected with a driving component 5, and the side surface of the placement plate 1 is fixedly connected with a protective component 6.

[0029] One aspect of the application of this embodiment is that the pay-off wheels 4 fixed by the rotating rod 3 rotate synchronously in opposite directions, pushing the cable placed between the two pay-off wheels 4, and directly pulling the cable out from the inside of the coil, without manually pulling the cable accumulated on the ground again, thereby improving the convenience of operation. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supplies.

[0030] like Figure 3 As shown, both sides of the rotating gear 531 of this embodiment are meshed with driven gears 532, and the driven gears 532 are fixedly connected to the bottom end of the rotating rod 3; when the rotating gear 531 rotates, it will drive the two meshed driven gears 532 on both sides to rotate in opposite directions, so that the top surface of the pay-off wheel 4 connected to the rotating rod 3 rotates synchronously, pushing and pulling the cable placed between the two pay-off wheels 4.

[0031] like Figure 3 As shown, the bottom surface of the driven gear 532 of this embodiment is fixedly connected with a connecting block 7, and the bottom end of the connecting block 7 is sleeved with a bearing 8 for rotation. The bearing 8 is axially symmetrically fixedly connected to the top surface of the equipment box 51. When the driven gear 532 rotates, it rotates inside the bearing 8 through the bottom connecting block 7, so that the driven gear 532 rotates more smoothly, avoiding affecting the traction effect of the upper pay-off wheel 4.

[0032] like Figure 2 As shown, one end of the buffer structure 61 of the present embodiment is fixedly connected to a rotation groove 62, and the rotation groove 62 is rotatably connected to a roller 63 through the jacks opened on both sides. When the cable placement plate 1 moves outward, it rubs against the roller 63, causing it to rotate in the rotation groove 62, and the sliding friction generated by the direct contact between the cable and the placement plate 1 is changed into rolling friction after contacting the roller 63, thereby greatly reducing the friction force and avoiding wear on the cable surface.

[0033] like Figure 2 As shown, the sleeve 611 of this embodiment is internally slidably connected to a slide bar 612, and the side of the sleeve 611 is fixedly connected to the slide bar 612 via a spring 613.

[0034] like Figure 4 As shown, the bottom surface of the placement plate 1 of the present embodiment is axially symmetrically fixedly connected to the side plate 9, the bottom surface of the side plate 9 is fixedly connected to the bottom plate 10, the bottom surface of the bottom plate 10 is axially symmetrically fixedly connected to the universal wheel 11, and the interior of the universal wheel 11 is provided with a brake mechanism, which can effectively start and stop the universal wheel 11, so as to facilitate the overall traction device to be stably placed in a fixed location.

[0035] Embodiment 1:

[0036] In this embodiment, a driving motor 52 is sleeved inside the device box 51, and a rotating gear 531 is fixedly connected to the output end of the driving motor 52. Both sides of the rotating gear 531 are meshed with driven gears 532. The driven gear 532 is fixedly connected to the bottom end of the rotating rod 3, and a pay-off wheel 4 is sleeved on the surface of the rotating rod 3.

[0037] Through the setting of the driving component 5, the driving motor 52 drives the rotating gear 531 fixed on the top of the output end to rotate, so that the driven gears 532 meshing on both sides thereof rotate in opposite directions, and drive the pay-off wheel 4 fixed on the top surface by the rotating rod 3 to rotate synchronously in opposite directions, and push the cable placed between the two pay-off wheels 4, thereby achieving the effect of directly pulling the cable out from the inside of the coil, without the need for manual pulling of the cable accumulated on the ground, thereby improving the convenience of operation.

[0038] Embodiment 2:

[0039] In this embodiment, a slide bar 612 is slidably connected inside the sleeve 611, and the side of the sleeve 611 is fixedly connected to the slide bar 612 via a spring 613. One end of the slide bar 612 is fixedly connected to a rotating groove 62, and the rotating groove 62 is rotatably connected to a roller 63 via jacks provided on both sides.

[0040] By setting the protection component 6, the cable pulled out by the pay-off wheel 4 moves against the roller 63 connected to the rotation groove 62 to avoid the wear of the cable surface caused by sliding friction. At the same time, the cable with higher weight will push the slide bar 612 fixed on the back of the rotation groove 62 to move. The slide bar 612 will compress the spring 613 when it moves. During the contraction of the spring 613, the squeezing of the cable on the roller 63 will be buffered to avoid the cable surface from being crushed, thereby protecting the moving cable from wear or crushing.
