Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration damping technology for power transmission lines, specifically to a vibration damping and anti-shaking suspension device for power transmission lines. Background Technology
[0002] Vibration dampers are protective hardware installed on conductors to suppress or reduce vibrations caused by light winds. They are designed to reduce the vibration of conductors caused by wind. Vibration dampers generally consist of a certain number of weights, galvanized steel strands with high elasticity and strength, and clamps. The vibration damping performance of a vibration damper is related to its effective operating frequency range. When a conductor vibrates, the relative movement of the vibration dampers suspended on the conductor absorbs the vibration energy of the conductor, thereby reducing and eliminating the vibration of the conductor.
[0003] Existing vibration dampers are generally installed using bolts. However, under long-term light wind vibration, the bolts may loosen, causing the damper to slide on the conductor and affecting its placement effect. To address this, we propose a vibration damping and anti-shaking suspension device for transmission lines. Utility Model Content
[0004] The purpose of this utility model is to provide a vibration-damping suspension device for power transmission lines, in order to solve the problem mentioned in the background art that the bolts of the vibration damper will loosen under long-term light wind vibration, which will cause the vibration damper to slide on the conductor and thus affect the placement effect of the vibration damper.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a vibration-damping and anti-vibration suspension device for power transmission lines, comprising a lower clamping plate and a mounting box. The mounting box is fixedly connected to the bottom of the lower clamping plate. Screws are inserted into the front and rear sides of the top of the lower clamping plate. An upper clamping plate is fixedly connected to the top of the screws. A threaded sleeve is screwed to the lower side of the outer side wall of the screws. The outer side wall of the threaded sleeve has anti-slip textures. A bidirectional screw is rotatably connected to the bottom of the lower clamping plate. The end of the bidirectional screw passes through the mounting box and extends to the bottom of the mounting box. A knob is fixedly connected to the end of the bidirectional screw. Moving plates are screwed to the upper and lower sides of the outer side wall of the bidirectional screw. Connecting rods are rotatably connected to the front and rear side walls of the moving plates. A clamping plate is rotatably connected to the end of the connecting rod.
[0006] As a further description of the above technical solution:
[0007] A guide rod is fixedly connected to the bottom of the inner cavity of the mounting box, and the movable plate is slidably connected to the outer wall of the guide rod.
[0008] As a further description of the above technical solution:
[0009] A vertical rod is fixedly connected to the bottom center of the mounting box, and a connecting block is fixedly connected to the end of the vertical rod.
[0010] As a further description of the above technical solution:
[0011] Steel strands are fixedly connected to the left and right side walls of the connecting block, and hammers are fixedly connected to the ends of the steel strands.
[0012] As a further description of the above technical solution:
[0013] The left and right side walls of the mounting box are fixedly connected to a first pull rope, the end of the first pull rope is fixedly connected to a cylinder, the top of the inner cavity of the cylinder is fixedly connected to a spring, and a damping rod is sleeved in the inner cavity of the spring.
[0014] As a further description of the above technical solution:
[0015] The spring has a movable block fixedly connected to its end, and a second pull rope is fixedly connected to the bottom of the movable block. The end of the second pull rope is fixedly connected to the top of the hammer.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This vibration-damping suspension device for power transmission lines fixes the entire device to the power transmission line by tightening the threaded sleeve onto the screw rod, causing the upper and lower clamping plates to close together. Then, by rotating the knob, the double-acting screw is rotated, which in turn moves the moving plate. The moving plate then moves the connecting rod, which in turn moves the abutment plate to both sides, thus pressing the abutment plate tightly against the threaded sleeve and locking the threaded sleeve in place. This prevents the threaded sleeve from loosening from the screw rod, ensuring that the device is firmly fixed to the power transmission line and guaranteeing its vibration-damping effect.
[0018] 2. This vibration-damping suspension device for power transmission lines uses a hammer that pulls a second rope when it vibrates. The second rope then pulls a movable block, which in turn causes a spring and a damping rod to buffer the vibration, thereby shortening the hammer's vibration time and reducing the risk of conductor fatigue damage. This results in a better vibration-damping effect and improves the device's performance. Attached Figure Description

[0028] This utility model provides a vibration-damping and anti-vibration suspension device for power transmission lines. It can be firmly fixed to the power transmission line, ensuring the device's vibration-damping effect and providing better anti-vibration and anti-vibration performance, thus improving the device's overall performance. Please refer to [link / reference needed]. Figure 1-5 It includes a lower clamping plate 100 and a mounting box 200;
[0029] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 A screw rod 110 is inserted into the front and rear sides of the top of the lower clamping plate 100. An upper clamping plate 120 is fixedly connected to the top of the screw rod 110. A threaded sleeve 130 is screwed to the lower side of the outer wall of the screw rod 110. The outer wall of the threaded sleeve 130 has anti-slip texture 131. A double-acting screw rod 140 is rotatably connected to the bottom of the lower clamping plate 100. The end of the double-acting screw rod 140 passes through the mounting box 200 and extends to the bottom of the mounting box 200. A knob 141 is fixedly connected to the end of the double-acting screw rod 140. A movable plate 150 is screwed to the upper and lower sides of the outer wall of the double-acting screw rod 140. A connecting rod 160 is rotatably connected to the front and rear side walls of the movable plate 150. The end of 160 is rotatably connected to a clamping plate 170. By tightening the threaded sleeve 130 onto the screw 110, the upper clamping plate 120 and the lower clamping plate 100 are closed together, thereby fixing the entire device onto the power transmission line. Then, by rotating the knob 141, the bidirectional screw 140 is rotated, which in turn drives the moving plate 150 to move. The moving plate 150 then drives the connecting rod 160 to move, which in turn drives the clamping plate 170 to move to both sides, thereby making the clamping plate 170 press tightly against the threaded sleeve 130, thus locking the threaded sleeve 130 and preventing it from loosening from the screw 110.
[0030] In summary, this allows the device to be firmly fixed to the power transmission line, ensuring its vibration damping effect.
[0031] Please see Figure 1-4The mounting box 200 is fixedly connected to the bottom of the lower clamping plate 100. A guide rod 210 is fixedly connected to the bottom of the inner cavity of the mounting box 200. A movable plate 150 is slidably connected to the outer wall of the guide rod 210. A vertical rod 220 is fixedly connected to the middle of the bottom of the mounting box 200. A connecting block 230 is fixedly connected to the end of the vertical rod 220. Steel strands 240 are fixedly connected to the left and right side walls of the connecting block 230. A hammer 250 is fixedly connected to the end of the steel strands 240. A first pull rope 260 is fixedly connected to the left and right side walls of the mounting box 200. A cylinder 270 is fixedly connected to the end of the first pull rope 260. A spring 280 is fixedly connected to the top of the inner cavity of the cylinder 270. A damping rod 281 is sleeved inside the inner cavity of the spring 280. A movable block 290 is fixedly connected to the end of the spring 280. A second pull rope 291 is fixedly connected to the bottom of the movable block 290. The end of the second pull rope 291 is fixedly connected to the top of the hammer head 250. When the hammer head 250 vibrates, it pulls the second pull rope 291, which in turn pulls the movable block 290. This causes the spring 280 to work with the damping rod 281 to buffer the vibration, thereby shortening the vibration time of the hammer head 250 and reducing the risk of fatigue damage to the conductor.
[0032] In summary, this results in better vibration and shock absorption of the device, improving its performance.
[0033] In practical use, those skilled in the art first remove the upper clamping plate 120 from the lower clamping plate 100, then place the lower clamping plate 100 below the wire, and then put the upper clamping plate 120 over the wire, simultaneously inserting the screw 110 at the bottom of the upper clamping plate 120 into the lower clamping plate 100. Then, by tightening the threaded sleeve 130 onto the screw 110, the upper clamping plate 120 and the lower clamping plate 100 are fixed together, thus fixing the device to the wire. Subsequently, by rotating the knob 141, the bidirectional lead screw 140 is rotated, causing the double... The lead screw 140 drives the moving plate 150 to move, and the moving plate 150 drives the connecting rod 160 to move, so that the connecting rod 160 drives the pressing plate 170 to move to both sides, so that the pressing plate 170 presses tightly against the threaded sleeve 130, thereby locking the threaded sleeve 130. Then, when the hammer 250 vibrates, the hammer 250 pulls the second pull rope 291, and the second pull rope 291 pulls the movable block 290, so that the spring 280 cooperates with the damping rod 281 to buffer, thereby shortening the vibration time of the hammer 250.
