DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1 The utility model provides a technical solution: a power construction tightening device.

[0027] In this embodiment, the control box 2 is connected to the rotating shaft 202 through the cable 201, and the rotating shaft 202 is controlled to rotate. The rotating shaft 202 drives the rotating rod 203 to rotate. One end of the rotating rod 203 is connected to the rotating shaft 202, and the other end is connected to the connecting pull block 204. The rotating rod 203 rotates with the rotating shaft 202 as the axis, driving the connecting pull block 204 to make a circular motion. The connecting pull block 204 is thick at both ends and thin in the middle. At the same time, a long hole is opened in the center of the sliding rod 304. The hole width is the same as the center diameter of the connecting pull block 204. The connecting pull block 204 is embedded in the center of the sliding rod 304. When the connecting pull block 204 makes a circular motion, it will pull the sliding rod 304 to the left and right. Movement, the connecting pull block 204 rotates half a circle, the sliding bar 304 moves from one side to the other side, the connecting pull block 204 continues to rotate the remaining half a circle, and the sliding bar 304 moves back from the other side. Every time the connecting pull block 204 rotates one circle, the sliding bar 304 completes a reciprocating motion. The movement of the sliding bar 304 drives the moving plate 3 and the support rod 301 to move, thereby driving the top guide base 4 to make a left and right reciprocating motion. The wire passes between the clamping plates 405 on the guide base 4. The back and forth movement of the guide base 4 changes the position of the wire tightened to the take-up roller 502, so that the take-up roller 502 collects the wire more evenly, thereby improving the collection effect.

[0028] Among them, a pallet 104 and a pallet 2 106 are fixedly connected to the bottom of the workbench 1, the pallet 104 is located on the front of the slide rail 101, the pallet 2 106 is located on the front of the control box 2, a movable groove 105 is opened on the back of the pallet 104, and a movable groove 2 107 is opened on the front of the pallet 2 106, the back of the movable plate 3 is fixedly connected to an extension plate 302, the back of the extension plate 302 is fixedly connected to a boss 1 303, and the front of the slide rod 304 is fixedly connected to a boss 2 305.

[0029] The extension plate 302 on the front of the movable plate 3 is wider than the movable plate 3, and the extension plate 302 is closely attached to the long side of the pallet 104, so that when the slide bar 304 pulls the movable plate 3 to make a reciprocating motion, the extension plate 302 is always attached to the side of the pallet 104, so that the slide bar 304 is always perpendicular to the pallet 104, and the slide bar 304 will not be pulled by the connecting pull block 204 to change the angle, thereby affecting the back and forth movement of the support rod 301; the pallet 104 and the pallet 2 106 are L-shaped, fixed one front and one rear at the bottom of the workbench 1, and the short sides extending from the two are both toward the position of the rotating shaft 202 at the bottom of the workbench 1, the short side of the pallet 104 supports the movable plate 3, and the short side of the pallet 2 106 supports the slide bar 30 4, and in the position facing the short side, a moving groove 105 is opened on the long side of the pallet 104, and a moving groove 2 107 is opened on the long side of the pallet 106, a boss 303 is inserted in the moving groove 105, and the boss 1 303 is fixedly connected to the extension plate 302. When the movable plate 3 follows the slide bar 304 to make reciprocating motion, the boss 1 303 moves in the moving groove 105 to assist the movement of the movable plate 3. Similarly, the boss 2 305 fixedly connected to the top of the slide bar 304 is embedded in the moving groove 2 107. When the two bosses move with the movable plate 3 and the slide bar 304, it is ensured that the extension plate 302 is always in contact with the pallet 104 to avoid changes in the vertical angle between the slide bar 304 and the two pallets, which may cause derailment.

[0030] A spring 404 is installed inside the spring box 401 , and the spring 404 is sleeved on the telescopic rod 402 . A baffle 403 is fixedly connected to the center position of the outer side of the telescopic rod 402 .

[0031] In this embodiment, the spring 404 in the left spring box 401 is arranged on the left side of the baffle 403, and the spring 404 in the right spring box 401 is arranged on the right side of the baffle 403. In this way, the two springs 404 squeeze the baffle 403 so that the clamping plates 405 on the left and right sides are close to the center, thereby clamping the wires between the two clamping plates 405. As the guide base 4 follows the movement of the movable plate 3, the two clamping plates 405 also move accordingly, so that the wires also move accordingly, changing the wire collection position. The compression and release of the spring 404 makes the reciprocating motion of the support rod 301 smoother when changing direction. At the same time, the adjustability of the distance between the clamping plates 405 also enables the clamping plates 405 to clamp wires of various sizes.

[0032] A roller 406 is installed at the center of the clamping plate 405 .

[0033] In this embodiment, the roller 406 at the center of the clamping plate 405 rotates in contact with the wire when winding the wire, thereby reducing the friction between the wire and the clamping plate 405, making winding the wire easier.

[0034] Among them, hydraulic rods 102 are arranged at the four corners of the bottom of the workbench 1 , and a hydraulic cylinder 103 is arranged at the bottom of the hydraulic rods 102 .

[0035] In this embodiment, the hydraulic cylinder 103 controls the extension and contraction of the hydraulic rod 102, and the hydraulic rod 102 lifts the workbench 1 to adjust the distance from the line-reeling position to the ground to cope with line-reeling and tightening work at various heights.

[0036] Among them, casters 6 are arranged at the bottom of the hydraulic cylinder 103 .

[0037] In this embodiment, the casters 6 allow the workbench 1 to be movable, greatly improving the portability of the entire device.

[0038] Working principle: The electric power construction tightening device first adjusts the height of the workbench 1 through the hydraulic cylinder 103, passes the wire through the two clamping plates 405, fixes one end of the wire on the wire take-up roller 502, starts the motor 501, and the wire take-up roller 502 rotates to take up the wire. At the same time, the control box 2 is started, and the control box 2 drives the rotating shaft 202 to rotate through the cable 201, and the rotating shaft 202 drives the rotating rod 203 to rotate. The rotating rod 203 drives the connecting pull block 204 at one end to make a circular motion. The connecting pull block 204 moves on the sliding rod 30 4 drives the slide bar 304 inside to convert the circular motion into reciprocating motion, so that the support rod 301 on the top of the movable plate 3 moves left and right in the slide rail 101, thereby driving the guide base 4 on the top of the support rod 301 to move left and right. As the guide base 4 drives the two spring boxes 401 to move, the telescopic rod 402 in the spring box 401 drives the clamping plate 405 to move, so that the clamping plate 405 continuously adjusts the position of the wire on the wire-receiving roller 502 during the wire-receiving process, the wire-receiving is more uniform, and the tightening effect is improved.
