[0027] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, rather than all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the utility model.
[0028] In the description of the present utility model, it should be understood that terms such as "open hole", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.
[0029] Please refer to Figures 1 - 6 As shown, the present utility model is a power tower with adjustable cable tension, including a tower frame 1. An adjusting component 2 is fixedly connected to the outer surface of the tower frame 1. A wire threading component 3 is rotatably connected to the outer surface of the adjusting component 2. A first limiting component 4 is arranged between the adjusting component 2 and the wire threading component 3. A second limiting component 5 is arranged inside the wire threading component 3. The adjusting component 2 is used to drive the wire threading component 3 to move. The first limiting component 4 is used to fix the wire threading component 3. The second limiting component 5 is used to fix the cable.
[0030] Thread the cable through the wire threading component 3 on the tower frame 1 in an S shape. When changing the length of the adjusting component 2 on the tower frame 1, the wire threading component 3 moves up and down along with the adjusting component 2. When the wire threading component 3 moves upward, the cable is tightened. When the first limiting component 4 is removed to release the limit fixation of the wire threading component 3, the wire threading component 3 can be pushed to rotate. At this time, the wire threading component 3 is in an inclined state and winds the cable, enabling the cable to be further tightened. During the rotation of the wire threading component 3, the second limiting component 5 pushes the cable to make it close to the wire threading component 3. When the adjusting component 2 drives the wire threading component 3 to move downward, the cable on the wire threading component 3 is in a slack state.
[0031] In the present utility model, through the connection between the adjusting component 2 and the wire threading component 3, the wire threading component 3 is fixed at the bottom of the adjusting component 2. When the adjusting component 2 extends downward, the wire threading component 3 moves downward along with the adjusting component 2, making the cable in a slack state. When the adjusting component 2 retracts upward, the wire threading component 3 drives the cable to be tightened. After removing the first limiting component 4 to release the limit fixation of the wire threading component 3, the wire threading component 3 rotates clockwise, enabling the cable in an S shape inside it to be tightened again, which is more convenient during adjustment.
[0032] In one embodiment, for the above-mentioned adjusting component 2, the adjusting component 2 includes a T-shaped column 201. The T-shaped column 201 is fixedly connected to the tower frame 1. A first sliding groove 202 is opened inside the T-shaped column 201. A sliding rod 203 is slidably connected inside the first sliding groove 202. A first limiting hole 204 is opened on the outer surface of the sliding rod 203. A first bolt 205 is threadedly connected to the outer surface of the T-shaped column 201. The first bolt 205 passes through the T-shaped column 201 and extends into the first limiting hole 204.
[0033] Remove the first bolt 205 to separate it from the first limiting hole 204 on the sliding rod 203, release the limiting fixation between the sliding rod 203 and the T-shaped column 201, and pull the sliding rod 203 to slide along the first sliding groove 202, thereby changing the length of the sliding rod 203 extending from the first sliding groove 202.
[0034] In one embodiment, for the above-mentioned wire threading assembly 3, the wire threading assembly 3 includes a first rotating shaft 301, the first rotating shaft 301 is rotatably connected to the sliding rod 203, the outer surface of the first rotating shaft 301 is fixedly connected with a rotating frame 302, a square groove 303 is formed on the outer surface of the rotating frame 302, a second rotating shaft 304 is rotatably connected to the outer surface of the rotating frame 302, the rotating frame 302 is rotatably connected with a pulley 305 through the second rotating shaft 304, and there are two groups of the pulleys 305 in total.
[0035] Pass the cable through the square groove 303 on the rotating frame 302. The cable passes above the first group of pulleys 305 in the square groove 303 and then bypasses below the second group of pulleys 305. At this time, the cable is in an S shape. When the sliding rod 203 moves, the cable can be driven to move synchronously through the rotating frame 302. When the rotating frame 302 and the cable move upward, the cable is in a taut state. Push the rotating frame 302 to rotate clockwise around the first rotating shaft 301, and at this time the cable will be further taut.
[0036] In one embodiment, for the above-mentioned first limiting assembly 4, the first limiting assembly 4 includes a second bolt 401, the second bolt 401 is threadedly connected to the outer surface of the sliding rod 203, a second limiting hole 402 is formed on the outer surface of the sliding rod 203, and the second bolt 401 passes through the second limiting hole 402 and extends into the interior of the rotating frame 302.
[0037] Remove the second bolt 401 to separate the second bolt 401 from the rotating frame 302 and release the limiting fixation of the rotating frame 302. At this time, the rotating frame 302 can be pushed to rotate around the first rotating shaft 402, so as to adjust the tension of the cable in the rotating frame 302.
[0038] In one embodiment, for the above-mentioned second limiting assembly 5, there are two groups of the second limiting assemblies 5. The two groups of the second limiting assemblies 5 are respectively located on the upper and lower sides of the two groups of pulleys 305. The second limiting assembly 5 includes a sliding plate 501, a spring 502 is fixedly connected to the top of the sliding plate 501, a second sliding groove 503 is formed in the interior of the rotating frame 302, the sliding plate 501 is slidably connected to the interior of the second sliding groove 503, and the spring 502 is fixedly connected to the interior of the second sliding groove 503.
[0039] The cable passes through between the pulley 305 and the sliding plate 501. When the rotating frame 302 drives the pulley 305 to rotate, the pulley 305 winds up the cable. At this time, the cable will push the sliding plate 501 and compress the spring 502. The spring 502 generates a reaction force to push the sliding plate 501 to press on the cable, fixing the cable to prevent the cable from slipping off the pulley 205.
[0040] In one embodiment, for the above-mentioned sliding rod 203, a limiting plate 6 is fixedly connected to the outer surface of the sliding rod 203, and the limiting plate 6 is slidably connected to the first chute 202.
[0041] In one embodiment, for the above-mentioned sliding plate 501, a soft pad 7 is fixedly connected to the bottom of the sliding plate 501.
[0042] The limiting plate 6 can only slide within the first chute 202. The moving distances of the limiting plate 6 and the sliding rod 203 are limited by the first chute 202 to prevent the sliding rod 203 from slipping out of the first chute 202. The soft pad 7 can prevent the sliding plate 501 from damaging the cable.
[0043] In summary, by means of the above technical solution of the present utility model, the cable is inserted into the square groove 303 on the rotating frame 302. After the cable passes through between the first set of pulleys 305 on the left and the sliding plate 501, it then winds around to between the second set of pulleys 305 on the right and the sliding plate 501. At this time, the cable is in an S shape. Push the sliding rod 203 to drive the rotating frame 302 and the cable to move upward, and fix the sliding rod 203 on the T-shaped column 201 through the first bolt 205. At this time, the cable is in a taut state. Push the rotating frame 302 to rotate clockwise around the first rotating shaft 301. The rotating frame 302 can wind up the cable, and fix the rotating frame 302 through the second bolt 401. At this time, the cable can be further tautened. When the sliding rod 203 drives the rotating frame 302 and the cable to move downward, the cable is in a slack state. The staff can adjust the tension of the cable in two ways: by changing the length of the sliding rod 203 extending out of the T-shaped column 201 and by changing the angle of the rotating frame 302.
[0044] Through the above technical solutions: 1. By adjusting the connection between the adjusting component 2 and the wire threading component 3, the wire threading component 3 is fixed at the bottom of the adjusting component 2. When the adjusting component 2 extends downward, the wire threading component 3 moves downward along with the adjusting component 2, making the cable in a slack state. When the adjusting component 2 retracts upward, the wire threading component 3 drives the cable to make it taut. After removing the first limiting component 4 to release the limit fixation of the wire threading component 3, the wire threading component 3 rotates clockwise, and the cable in an S shape inside it can be taut again, which is convenient for adjustment; 2. By connecting the sliding rod 203 and the sliding frame 302, the sliding frame 302 is rotatably connected to the outer surface of the sliding rod 203. When changing the position of the sliding rod 203, the sliding rod 203 can drive the sliding frame 302 to move. When the sliding frame 302 drives the pulley 305 and the cable to move upward, the cable can be in a taut state. Rotating the sliding frame 302 clockwise, the sliding frame 302 winds up the cable, making the cable further taut. When the sliding rod 203 drives the sliding frame 302 to move downward, the cable drops accordingly, making the cable in a slack state, which is convenient for adjusting the tension of the cable.
