When the connecting rod 552 moves downward, the second limit rod 557 is driven by the fixing rod 551 to slide downward in the second limit hole 54, so that when the round block quickly enters the installation groove 52, the second limit rod 557 can contact the side of the round block. At the same time, the material of the second limit rod 557 is rubber, thereby increasing the friction between the second limit rod 557 and the round block, thereby avoiding the phenomenon that the cable is broken due to excessive speed when the cable is pulled.

[0034] Example 2, using Figure 5-Figure 6 The protective cable tensioning device installed in power construction of the present invention is described as follows:

[0035] like Figure 5-Figure 6 It is shown that a protective cable tensioning device installed in power construction of the present invention is based on the first embodiment;

[0036] The guide component 4 includes a square groove 41, which is opened on the side of the base 1, and a roller 43 is slidably connected to the inner side of the square groove 41. Both sides of the roller 43 are fixedly connected to a slider 42. The side of the slider 42 is slidably connected to the inner side of the square groove 41. A sliding rod 46 is fixedly connected to the inner side of the square groove 41. The side of the sliding rod 46 is slidably connected to the inner side of the slider 42. A second spring 44 is sleeved on the sliding rod 46. One end of the second spring 44 is fixedly connected to the slider 42, and the other end of the second spring 44 is fixedly connected to the inner side of the square groove 41. A contact mechanism 45 is fixedly connected to the side of the base 1; at the same time, when the cable on the tensioning wheel 3 is laid through the square groove 41, the side of the cable is squeezed by the two rollers 43 in the square groove 41. When the cable passes between the two rollers 43, the cable can contact and rotate with the two rollers 43, thereby avoiding the phenomenon that the cable will bend during laying, and the cable after passing through the roller 43 can pass through the guide component 4;

[0037] The contact mechanism 45 comprises a contact plate 451, the side of the contact plate 451 is fixedly connected to the base 1, the side of the contact plate 451 is evenly provided with a slide groove 452, the inner side of the slide groove 452 is slidably connected with a connecting block 453, the side of the connecting block 453 is fixedly connected with an arc rod 454, the side of the arc rod 454 is provided with an arc groove 455, the inner side of the arc groove 455 is slidably connected with a moving block 457, and the side of the moving block 457 is rollingly connected with a ball 456; when the cable passes through the middle of the contact plate 451, it contacts the arc rod 454 through the cable, so that the cable can be limited and guided, and at the same time, when the arc rod 454 is squeezed by the cable, It can be driven to move in the slide groove 452 through the connecting block 453, and can then be adaptively adjusted according to the size of different cables. When the cable contacts and moves with the arc rod 454, the moving block 457 drives the ball 456 to move in the arc groove 455. When the cable passes through the contact plate 451, the ball 456 contacts and rolls with the cable, thereby limiting the position of the cable to prevent the cable from shaking when moving. At the same time, when the cable contacts and rolls with the ball 456, the friction between the cable and the cable is reduced, so that the cable can be laid faster through the guide component 4.

[0038] Example 3, using Figure 7-Figure 8 The protective cable tensioning device installed in power construction of the present invention is described as follows:

[0039] like Figure 7-Figure 8 It is shown that a protective cable tensioning device installed in power construction of the present invention is based on the first embodiment;

[0040] The moving component 6 includes a moving groove 61, which is opened at the bottom of the base 1, and a roller 62 is rotatably connected to the inner side of the moving groove 61, and a cleaning mechanism 63 is fixedly connected to one side of the inner side of the moving groove 61 close to the roller 62;

[0041] The cleaning mechanism 63 includes a sliding rod 631, one end of which is slidably connected to the inner side of the movable groove 61, and the other end of the sliding rod 631 is fixedly connected to a connecting plate 632, and a cleaning block 633 is fixedly connected to the side of the connecting plate 632. The side of the cleaning block 633 away from the sliding rod 631 contacts the inner side of the roller 62, and both sides of the cleaning block 633 are fixedly connected to a bent plate 634. The inner side of the cleaning block 633 is rotatably connected to a cleaning roller 635, and the side of the cleaning roller 635 contacts the side of the roller 62. A fourth spring 636 is sleeved on the sliding rod 631, and one end of the fourth spring 636 is fixedly connected to the connecting plate 632, and the other end of the fourth spring 636 is fixedly connected to the inner wall of the movable groove 61; when it is necessary to move the device, by pushing the base 1, the base 1 rotates through the roller 62, so that the roller 62 drives the device to move, and at the same time, the cleaning mechanism 63 can clean the rotating roller 62. When the wheel 62 rotates in the moving groove 61, the roller 62 and the cleaning block 633 move against each other, so that the cleaning block 633 can push out the impurities stuck on the inner side of the roller 62. At the same time, by providing curved plates 634 on both sides of the cleaning block 633, when the roller 62 and the cleaning block 633 move against each other, the curved plates 634 can scrape off the mud and impurities attached to the roller 62. At the same time, when the cleaning block 633 moves in contact with the roller 62, the cleaning roller 635 can use the curved plates 634 to clean and wipe the area cleaned by the roller 62. At the same time, when the cleaning block 633 cleans the roller 62, when the extrusion force between the cleaning block 633 and the impurities stuck on the roller 62 is greater than the tensile force of the fourth spring 636, the cleaning block 633 moves in the moving groove 61 through the sliding rod 631, so as to avoid excessive extrusion force between the impurities and the cleaning block 633, which would cause extrusion damage to the side of the roller 62.

[0042] The specific workflow is as follows:

[0043] During operation, after the base 1 is moved to a suitable position by the moving component 6, the cable is passed through the tensioning wheel 3, and at the same time, one end of the cable passes through the guide component 4, so as to avoid damage to the side of the cable when the cable is stretched. When the cable passes through the guide component 4, it can be avoided that the tensioning wheel 3 rotates too fast when the cable is pulled;

[0044] When the cable is pulled, the tension wheel 3 drives the cable to rotate on the fixing frame 51. By symmetrically arranging round blocks on the side of the tension wheel 3, when the round blocks rotate along with the tension wheel 3, the tension wheel 3 drives the round blocks to pass through the mounting groove 52, so that the round blocks and the limiting mechanism 55 are buffered to avoid the cable being pulled too fast, which may cause damage to the cable.

[0045] When the cable is pulled at a fast speed, the tension wheel 3 drives the round block to pass through the installation groove 52, so that the round block and the limit block 556 are squeezed, so that the limit block 556 drives the connecting rod 552 to move downward in the inner cavity of the installation groove 52 through the first limit rod 555, and at the same time squeezes the first spring 554. When the connecting rod 552 moves downward, the second limit rod 557 is driven by the fixing rod 551 to slide downward in the second limit hole 54, so that when the round block quickly passes through the installation groove 52, the second limit rod 557 can contact the side of the round block. At the same time, the material of the second limit rod 557 is rubber, so as to increase the friction between the second limit rod 557 and the round block, thereby avoiding the phenomenon that the cable is broken due to excessive speed when the cable is pulled;

[0046] At the same time, when the cable on the tension wheel 3 is laid through the square groove 41, the two rollers 43 in the square groove 41 squeeze the side of the cable. When the cable passes between the two rollers 43, the cable can contact and rotate with the two rollers 43, thereby avoiding the cable from bending during laying. After passing through the rollers 43, the cable can pass through the guide component 4.

[0047] When the cable passes through the middle of the contact plate 451, the cable contacts the arc rod 454, so that the cable can be limited and guided. At the same time, when the arc rod 454 is squeezed by the cable, it can be driven by the connecting block 453 to move in the slide groove 452, so that adaptive adjustment can be performed according to the size of different cables. When the cable contacts and moves with the arc rod 454, the moving block 457 drives the ball 456 to move in the arc groove 455, so that when the cable passes through the contact plate 451, the ball 456 contacts and rolls with the cable, so as to limit the position of the cable, and avoid the cable from shaking when moving. At the same time, when the cable passes through the contact, it contacts and rolls with the ball 456, so as to reduce the friction between the cable and the cable, so that the cable can be laid through the guide component 4 faster;

[0048] When the device needs to be moved, the base 1 is pushed, and the base 1 rotates through the roller 62, so that the roller 62 drives the device to move, and the cleaning mechanism 63 can clean the rotating roller 62. When the roller 62 rotates in the moving groove 61, the roller 62 and the cleaning block 633 move against each other, so that the cleaning block 633 can eject impurities stuck on the inner side of the roller 62. At the same time, bent plates 634 are provided on both sides of the cleaning block 633, so that when the roller 62 and the cleaning block 633 move against each other, the bent plates 634 can be removed. The dirt and impurities attached to the roller 62 can be scraped off. When the cleaning block 633 moves in contact with the roller 62, the cleaning roller 635 can clean and wipe the area cleaned by the curved plate 634. When the cleaning block 633 cleans the roller 62, if the extrusion force between the cleaning block 633 and the impurities stuck in the roller 62 is greater than the tensile force of the fourth spring 636, the cleaning block 633 moves in the moving groove 61 through the sliding rod 631, thereby avoiding excessive extrusion force between the impurities and the cleaning block 633, which would cause extrusion damage to the side of the roller 62.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
