[0020] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Example 1 Reference Figure 1 - Figure 6 This is the first embodiment of the present invention. This embodiment provides an installation device for a live-mounted vibration damper, which includes a vibration damping mechanism, an auxiliary mechanism, and an anti-displacement mechanism. Compared with the clamping method of traditional vibration dampers, the vibration damper will not fall off. It can be adjusted according to different sizes of cables 10 so that the vibration damper can be stably installed on the cable 10. At the same time, it can also restrict the lateral position of the vibration damper to prevent the vibration damper from slipping on the cable 10 during use.

[0022] Furthermore, the vibration damping mechanism can reduce the vibration of the cable 10 in the wind and increase the service life of the cable 10. It includes the cable 10 and hammers 11. The hammers 11 are located below the cable 10. There are two hammers 11. A spring rod 12 is provided between the two hammers 11. A fixing plate 13 is provided in the middle of the spring rod 12. A first through-hole 14 is provided on the fixing plate 13. A horizontal plate 15 is provided inside the first through-hole 14. The horizontal plate 15 is located on the top surface inside the first through-hole 14. A storage part 16 is provided on the fixing plate 13. A docking part 17 is provided on the storage part 16. A locking part 18 is provided on the docking part 17.

[0023] Furthermore, the storage unit 16 includes a first V-shaped block 161 disposed on the fixed plate 13. The first V-shaped block 161 is located on the top of the fixed plate 13. The first V-shaped block 161 is provided with a first pair of interfaces 162 and a first slide groove 163. There are four of each of the first pair of interfaces 162 and the first slide groove 163, arranged in pairs. The first pair of interfaces 162 and the first slide groove 163 are interconnected.

[0024] When in use, the operator can place the cable 10 inside the first V-shaped block 161 so that the cable 10 contacts the inner wall of the first V-shaped block 161.

[0025] Furthermore, the docking part 17 includes a second V-shaped block 171 disposed above the first V-shaped block 161. The opening of the second V-shaped block 171 faces downward. The second V-shaped block 171 is provided with a second pair of interfaces 172 and a second sliding groove 173. The second sliding groove 173 is located on the end face of the second V-shaped block 171, and the first sliding groove 163 is opposite to the second sliding groove 173. There are two second V-shaped blocks 171 and four second sliding grooves 173. A first slider 174 is disposed inside the second sliding groove 173. A short rod 175 and a first spring 176 are disposed on the first slider 174. One end of the first spring 176 is connected to the first slider 174, and the other end of the first spring 176 is connected to the inner wall of the second sliding groove 173. A rubber pad 177 is disposed on the inner wall of the second V-shaped block 171.

[0026] In use, the operator can press the second V-block 171 down above the cable 10. Through the setting of the first pair of interfaces 162 and the second pair of interfaces 172, the first V-block 161 and the second V-block 171 are interlocked until the rubber pad 177 contacts the cable 10. At the same time, the short rod 175 can enter the interior of the first slide groove 163 during its descent. Depending on the size of the cable 10, the short rod 175 can move inside the first slide groove 163 as it descends. Simultaneously, the first slide groove 163 can squeeze the short rod 175, causing the short rod 175 to drive the first slider 174 to move inside the second slide groove 173. The first slider 174 drives the first spring 176 to contract until the inner wall of the first V-block 161 contacts the cable 10. At the same time, the rubber pad 177 contacts the cable 10, thus completing the clamping of the cable 10.

[0027] Furthermore, the locking part 18 includes a strip opening 181 and a slot 182 disposed on the side wall of the second V-shaped block 171. The slot 182 and the strip opening 181 are interconnected. There are multiple strip openings 181, which are evenly distributed on the second V-shaped block 171. A hook plate 183 is installed on the horizontal plate 15, and the hook plate 183 is located below the strip opening 181.

[0028] In use, when the second V-block 171 descends, the hook plate 183 can enter the interior of the slot 182. The inner wall of the slot 182 can squeeze the hook plate 183, causing the hook plate 183 to bend towards the first V-block 161. When the hook plate 183 passes through the slot 181, the hook plate 183 returns to its original position and can enter the interior of the slot 181. The position of the hook plate 183 is restricted by the slot 181.

[0029] Furthermore, the auxiliary mechanism can be further adjusted according to the size of the cable 10, and anti-vibration hammers can be installed on cables 10 of different sizes. It includes a groove 20 and a second through-hole 21 on the fixing plate 13. The second through-hole 21 and the groove 20 are interconnected. A driving part 22 is provided on the fixing plate 13, and a limiting part 23 is provided inside the groove 20.

[0030] Furthermore, the drive unit 22 includes a threaded rod 221 disposed on the fixed plate 13. The threaded rod 221 is located in the middle of the fixed plate 13. A dial wheel 222 is disposed on the side wall of the threaded rod 221. The threaded rod 221 is fixedly connected to the dial wheel 222. The dial wheel 222 is rotatably connected to the fixed plate 13. A horizontal plate 15 is sleeved on the side wall of the threaded rod 221.

[0031] When in use, when the dial 222 is turned, the dial 222 can drive the threaded rod 221 to rotate together. When the threaded rod 221 rotates, the horizontal plate 15 can be raised and lowered on the side wall of the threaded rod 221. When the horizontal plate 15 descends, it drives the hook plate to descend, and the hook plate drives the second V-shaped plate to descend, further squeezing and clamping the cable 10.

[0032] Furthermore, the limiting part 23 includes a lifting plate 231 disposed inside the groove 20. The lifting plate 231 is provided with a lever 232, a second spring 233 and a limiting block 234. There are two levers 232, which are located on both sides of the fixed plate 13. One end of the second spring 233 is connected to the lifting plate 231 and the other end of the second spring 233 is connected to the inner wall of the groove 20. The limiting block 234 is located on the top of the lifting plate 231. A limiting groove 235 is provided on the side wall of the lever 222. The width of the limiting block 234 matches the width of the limiting groove 235.

[0033] It should be noted that the second spring 233 drives the lifting plate 231, and the lifting plate 231 drives the limiting block 234 to extend out of the groove 20. The limiting block 234 is located inside the limiting groove 235, locking the position of the dial 222 to prevent the dial 222 from rotating under other factors.

[0034] When in use, when the operator uses their thumb and forefinger to push the lever 232 downward, the lever 232 causes the lifting plate 231 to descend, the lifting plate 231 causes the second spring 233 to retract, and the lifting plate 231 causes the limiting block 234 to descend, removing the restriction on the dial 222. At this time, the operator can turn the dial 222.

[0035] Furthermore, the anti-displacement mechanism, which prevents the hammer 11 from shifting laterally on the cable 10 and affecting the vibration damping effect of the hammer 11, includes a lifting groove 30 and a wire groove 31 on the fixing plate 13. There are two lifting grooves 30 and two wire grooves 31. The two lifting grooves 30 are located on the two sides of the fixing plate 13 respectively. The lifting grooves 30 and the wire grooves 31 are interconnected. A reset part 32 is provided inside the lifting groove 30. A limit part 33 is provided on the reset part 32.

[0036] Furthermore, the reset part 32 includes a second slider 321 and a third spring 322 disposed inside the lifting groove 30. One end of the third spring 322 is connected to the second slider 321, and the other end of the third spring 322 is connected to the inner wall of the lifting groove 30. A pull rope 323 is connected to the second slider 321, and the third spring 322 is sleeved on the side wall of the pull rope 323.

[0037] It should be noted that, initially, the second slider 321 is located at the top of the lifting groove 30.

[0038] When in use, when the pull rope 323 is pulled, the pull rope 323 drives the second slider 321 to descend inside the lifting groove 30, and the second slider 321 can drive the third spring 322 to retract.

[0039] Furthermore, the limiting part 33 includes an inclined rod 331 disposed on the second slider 321. The angle between the inclined rod 331 and the cable 10 is 45°. A horizontal rod 332 is connected to the end of the inclined rod 331 away from the second slider 321. The length direction of the horizontal rod 332 is parallel to the length direction of the cable 10. A number of limiting pins 333 are disposed on the horizontal rod 332. The multiple limiting pins 333 are evenly distributed on the side wall of the horizontal rod 332 and are located between the horizontal rod 332 and the cable 10.

[0040] It should be noted that when the cable 10 contacts the inner wall of the first V-shaped block 161, the limiting pin 333 is inserted into the gap on the cable 10. At this time, the relative position of the crossbar 332 and the cable 10 can be fixed by the setting of the limiting pin 333.

[0041] When in use, when the second slider 321 descends, it can drive the crossbar 332 to descend. The crossbar 332 can drive the limit pin 333 to disengage from the cable 10. At this time, the operator can move the position of the anti-vibration hammer on the cable 10.

[0042] Working principle: To prevent cable 10 from swaying in strong winds, the workers first pushed the first V-block 161 upwards from below the cable 10, and then pushed the second V-block 171 downwards from above the cable 10, so that the first V-block 161 and the second V-block 171 were aligned. As the second V-block 171 descended, it moved the first slider 174 inside the second slide groove 173. The first slider 174 moved the short rod 175, causing it to enter the interior of the first slide groove 163. Under the pressure of the inner wall of the first slide groove 163, the short rod 175 moved inside the first slide groove 163, simultaneously moving the first slider... 174 moves inside the second slide 173, gradually reducing the space between the first V-block 161 and the second V-block 171, so that the inner wall of the first V-block 161 contacts the cable 10, and the rubber pad 177 on the second V-block 171 contacts the cable 10. At the same time, as the second V-block 171 descends, the hook plate 183 enters the interior of the slot 182. The inner wall of the slot 182 squeezes the hook plate 183, causing it to bend. When the hook plate 183 passes through the strip opening 181, it returns to its original position and can be inserted into the strip opening 181. At this point, the clamping of the cable 10 is completed. Compared with the clamping mechanism of the existing anti-vibration hammer, it will not fall off the cable 10.

[0043] To further adapt to the size of cable 10, when the hook plate is inserted to the deepest point of slot 182 and the second V-shaped block 171 is not in contact with cable 10, the operator first moves the lever 232 downwards. The lever 232 causes the lifting plate 231 to descend, which in turn causes the limiting block 234 to descend. The lifting plate 231 then causes the third spring 322 to contract, ultimately causing the limiting block 234 to disengage from the limiting groove 235, releasing the restriction on the lever 222. Simultaneously with the descent of the lifting plate 231, the lifting plate 231 can drive the pull rope 323, which in turn causes the second slider 321 to descend within the lifting groove 30. Block 321 causes the third spring 322 to contract, the second slider 321 causes the inclined rod 331 to descend, the inclined rod 331 causes the horizontal rod 332 to descend, the horizontal rod 332 causes the limiting pin 333 to descend, and then the worker turns the dial wheel 222, which can drive the threaded rod 221 to rotate. When the threaded rod 221 rotates, the horizontal plate 15 can descend on the side wall of the threaded rod 221. At the same time as the threaded rod 221 descends, it can drive the hook plate 183 to descend. The hook plate 183 drives the second V-shaped block 171 to descend, so that the second V-shaped block 171 descends further and contacts the cable 10, thus completing the compression and fixation of the cable 10.

[0044] To prevent the vibration damper from moving on the cable 10, when the first V-block 161 and the second V-block 171 have finished squeezing and fixing the cable 10, the operator releases the lever 232. The second spring 233 resumes and drives the lifting plate 231 to rise. The lifting plate 231 drives the limiting rod to rise and re-insert into the limiting groove 235, thus limiting the lever 222. At the same time, the third spring 322 resumes and drives the second slider 321 to rise. The second slider 321 drives the crossbar 332 to rise. The crossbar 332 drives the limiting pin 333 to insert into the gap at the bottom of the cable 10, thus locking the lateral position of the vibration damper and preventing the vibration damper from moving laterally on the cable 10 during operation.

[0045] Example 2 This is a second embodiment of the present invention, which provides an installation method for a live-line vibratory damper, comprising: determining the installation position of the vibratory damper on the cable 10; using an insulating shielding tool to insulate and shield the adjacent phase cable 10 and fittings, and confirming that the working safety distance meets the requirements of the live-line working procedure; aligning the first V-block 161 and the second V-block 171 so that the first V-block 161 and the second V-block 171 press and fix the cable 10; and inserting a limiting pin 333 into the gap of the cable 10.

[0046] Furthermore, the inner surfaces of the first V-shaped block 161 and the second V-shaped block 171 are pre-coated with conductive paste, which forms a conductive contact surface when squeezed.

[0047] Furthermore, the insulating shielding tool includes one of flexible insulating blankets, rigid insulating partitions, or insulating sheaths, and the insulating shielding coverage area includes at least 0.5 meters on each side of the work point for adjacent live parts.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
