Description

Technical Field

[0001] This utility model relates to the field of wire and cable construction technology, and in particular to a tensioning device for wire and cable laying. Background Technology

[0002] In fields such as power transmission and communication network construction, the efficient and safe laying of wires and cables is the foundation for ensuring the stable operation of the system. At present, tensioning devices are often used to fix and tighten the cables during the laying process to ensure that the cables maintain appropriate tension after laying, so as to avoid safety hazards caused by slack or damage to the cables due to excessive tension.

[0003] Chinese Patent No. CN218335240U discloses a tensioning device for laying electrical wires and cables, including a horizontal mounting plate, a vertical mounting plate, and a tensioning mechanism. Guide wheels are provided at both ends of the horizontal mounting plate. The vertical mounting plate is fixedly connected to the middle of the bottom end of the horizontal mounting plate. The tensioning mechanism is disposed on the vertical mounting plate and includes a mounting groove extending through the surface of the vertical mounting plate along its length. This device, by setting up a tensioning mechanism, can tighten the cable when it has been laid to a certain extent to prevent it from becoming loose and sagging. When using the device, simply place the cable between the tensioning wheel and the guide wheel, and rotate the handle to make the tensioning wheel make tight contact with the cable surface. Then, the cable will be tightened by the rotation of the tensioning wheel. This device is convenient and quick to use, and can quickly tighten the cable, thus improving its practicality.

[0004] In today's reality with a large number of power towers, cables, and wires, this device, which can only pull in a single cable, has obvious limitations. In large-scale power construction or maintenance operations, using this device requires pulling in each cable sequentially, which not only leads to extremely low construction efficiency but also significantly increases construction time and labor costs.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1-5 As shown, a tensioning device for laying wires and cables includes a guide rod 1 and a connecting seat 3. A hanging frame 2 is fixedly connected to the upper sides of both ends of the guide rod 1 in the height direction. A guide rail 4 that slides with the guide rod 1 is fixedly connected to the middle of the rear end of the connecting seat 3. Multiple limiting components 5 are symmetrically arranged on the left and right sides of the outer surface of the connecting seat 3. A tensioning component 6 is arranged between the guide rod 1 and the connecting seat 3.

[0025] In actual use, the guide rod 1 is installed on the power tower through the top hanging frame 2 by bolt threads. The limiting component 5 on the connecting seat 3 is used to limit the movement of multiple wires and cables. At the same time, the tensioning component 6 pulls the connecting seat 3 to slide along the height direction of the guide rod 1, so that the multiple wires and cables on the connecting seat 3 slide together, thus achieving the purpose of tensioning multiple wires and cables.

[0026] By setting the limit component 5, different specifications of wires and cables can be limited, and the precise limiting of different specifications of cables can be completed quickly, which significantly improves the versatility and operational efficiency in the cable processing and installation process.

[0027] Specifically, the tensioning assembly 6 includes a connecting ring 61, a connecting frame 62, and a winding frame 64. The connecting ring 61 is fixedly installed at the top center of the connecting seat 3, the connecting frame 62 is fixedly installed at the top of the guide rod 1, and a concave wheel 63 is rotatably connected to the upper inner cavity of the front part of the connecting frame 62. The winding frame 64 is fixedly installed at the back end of the guide rod 1.

[0028] A take-up roller 65 is horizontally rotatably installed in the inner cavity of the take-up frame 64. The two ends of the take-up roller 65 pass through the two ends of the inner cavity of the take-up frame 64 respectively. The right end of the take-up roller 65 is eccentrically connected to a rocker plate 66. A cable is wound and connected to the outer surface of the take-up roller 65. The downstream side of the cable passes through a concave wheel 63 and is fixedly tied to a connecting ring 61.

[0029] Furthermore, a protective box 67 is fixedly connected to the left end of the take-up frame 64. A sliding hole 671 is provided through the middle of the top of the protective box 67. A limit gear 68 is rotatably connected to the lower side of the inner cavity of the protective box 67. The limit gear 68 is fixedly connected to the left end of the take-up roller 65.

[0030] After multiple cables are respectively limited to the connecting seat 3 by the limiting component 5, the rotating disc 66 rotates forward. The disc 66 drives the cable on the winding roller 65 to wind up. As the cable is wound up, the connecting ring 61 at the top of the connecting seat 3 is pulled upward, so that multiple wires and cables on the connecting seat 3 are lifted up, thereby achieving a tightening effect and preventing the wires and cables from dragging on the ground due to slack and causing damage.

[0031] A pull rod 672 is slidably connected to the inner cavity of the sliding hole 671. A locking block 673 that engages with the limiting gear 68 is fixedly connected to one end of the pull rod 672 near the limiting gear 68. A second spring 674 is sleeved on the outer surface of the pull rod 672. The two ends of the second spring 674 abut against the top of the inner cavity of the protective box 67 and the locking block 673, respectively.

[0032] When the rocker 66 is turned, the lever 672 first pulls the locking block 673 away from the limiting gear 68, thus releasing the limiting effect between the locking block 673 and the limiting gear 68. The rocker 66 can then rotate the winding roller 65 to wind up the cable. Conversely, when the lever 672 is released, the tension of the spring 674 pushes the locking block 673 back to its original position and maintain the locking effect with the limiting gear 68, preventing unnecessary rotation of the winding roller 65 due to external pulling force.

[0033] Furthermore, the limiting component 5 includes multiple limiting frames 51, which are equidistantly installed on both sides of the outer end face of the connecting seat 3. Two limiting holes 52 are symmetrically opened on the upper sides of both ends of the multiple limiting frames 51 in the height direction. Locking rods 53 are slidably connected between the inner surfaces of the two limiting holes 52 on the same side.

[0034] One end of each of the multiple locking rods 53 is connected to a multiple pull handle 532. The outer surface of each of the multiple locking rods 53 is fixedly connected to a spring 534 on the side away from the multiple pull handles 532. The first and last ends of the multiple springs 534 are respectively held between the multiple stop rings 531 and the end walls of the multiple limit frames 51 in the height direction of the inner cavity.

[0035] Pull the handle 532 to move the locking rod 53 out of the limiting hole 52 on one side. After the wire and cable are placed into the limiting frame 51, release the handle 532. The tension of the spring 534 pushes the stop ring 531 to move the locking rod 53 back to the limiting hole 52. In this way, the wire and cable can be locked in the limiting frame 51.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
