[0011] The present invention also provides another technical solution: an installation method for a lightning arrester, including the following steps: S1. Fix the upper crossbeam on the two wires located on the upper layer through the mounting buckles at both ends of the upper crossbeam. Then rotate the turning handle to drive the worm to rotate through the turning handle. When the worm rotates, drive the transmission rod to rotate through the worm gear, drive the second bevel gears at both ends of the worm gear to rotate through the worm gear. At this time, drive the first bevel gear to rotate through the second bevel gear, so that the adjusting nut rotates following the first bevel gear. When the adjusting nut rotates, drive the lead screw to move up and down, drive the lower crossbeam to move up and down through the lead screw, and make the traction wheel move up and down following the lower crossbeam, thereby adjusting the suspension point stroke. S2. Slip the towing rope over the towing wheel, fix the load-bearing rope inside the reel, pull the towing rope to drive the lightning arrester to rise. When the lightning arrester rises close to the lower crossbeam, insert the synchronization frame at the top of the lightning arrester to make the synchronization frame engage with the top of the lightning arrester. Then insert the stud at the bottom of the rack into the adjustment slot, and insert the top of the rack into the protective cover to make the top of the rack engage with the tightening gear. Then turn the fastening nut upward to fix the stud and the synchronization frame through the fastening nut. S3. Pull the towing rope again to make the lightning arrester rise. At this time, drive the rack to rise through the synchronization frame, drive the tightening gear to rotate through the rack, drive the reel to rotate through the rack, so that the reel rotates simultaneously with the reel. At this time, wind up the load-bearing rope through the reel. At this time, the towing rope can be released. At this time, the towing rope is not stressed, and the lightning arrester is vertically loaded through the reel and the load-bearing rope. Rotate the handwheel again to drive the lower crossbeam to rise. After adjusting the lower crossbeam to the appropriate position, pull the towing rope again to drive the lightning arrester to rise, and drive the rack to rise while the lightning arrester rises, so that the reel winds up the load-bearing rope at the same time. S4. When the rack rises with the lightning arrester, drive the reel to rotate and drive the ratchet to rotate while driving the tightening gear. The ratchet pushes the block into the fixed box, and the block is kept in contact with the ratchet through the spring. When the towing rope is released for the first time, the lightning arrester has a tendency to move downward, but due to the engagement of the block and the ratchet, the ratchet cannot reverse, so that the reel is fixed to realize the vertical load on the lightning arrester.

[0012] Compared with the prior art, the beneficial effects of the present invention are: By adjusting the height of the lower crossbeam to adjust the height of the towing wheel, the present invention realizes the adjustment of the hanging point. After the hanging point is adjusted, pull the towing rope to lift the lightning arrester close to the lower crossbeam, and then drive the rack to rise through the lightning arrester to drive the reel to wind up the load-bearing rope. And through the engagement of the ratchet and the block, the reel and the load-bearing rope can realize the vertical load on the lightning arrester when the towing rope is not stressed. After the towing rope is not stressed, the height of the hanging point can be adjusted again to increase the height of the hanging point, improve the lifting stroke when hoisting the lightning arrester, avoid the unbalanced force on both sides of the conductor, and avoid the operator from swaying left and right. It not only improves the installation efficiency and installation effect, but also avoids serious swaying and improves the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

The worm gear 206 is fixedly sleeved in the middle of the transmission rod 203 through bolts; by driving the transmission rod 203 to rotate through the worm gear 206, the second bevel gears 204 at both ends of the worm gear 206 are driven to rotate. At this time, the first bevel gear 202 is driven to rotate through the second bevel gear 204, so that the adjusting sleeve 201 rotates following the first bevel gear 202. When the adjusting sleeve 201 rotates, the lead screw 209 is driven to lift and lower, and the lower crossbeam 210 is driven to lift and lower by the lead screw 209, so that the traction wheel 301 follows the lower crossbeam 210 to lift and lower, thereby adjusting the suspension point stroke; The suspension point adjusting mechanism 2 includes a worm 207, a turning handle 208 and mounting buckles 211. The worm 207 is movably installed in the middle of the inside of the protective cover 205 through a bearing and is located above the worm gear 206.

By pulling the traction rope 302, the lightning arrester 303 is driven to rise. By the rack 402, the reel 304 is driven to rotate, so that the winding wheel 305 rotates simultaneously with the reel 304. At this time, the load-bearing rope 310 is wound by the winding wheel 305. The traction mechanism 3 includes a fixed box 307, a clamping block 308 and a spring 309. The fixed box 307 is fixedly installed on the front side of the upper crossbeam 1 through bolts.

[0018] The present invention also provides another technical solution: a method for installing a lightning arrester, including the following steps: S1. Fix the upper beam 1 to the two wires on the upper layer through the mounting buckles 211 at both ends of the upper beam 1, and then turn the handle 208 to drive the worm 207 to rotate. When the worm 207 rotates, the transmission rod 203 is driven to rotate through the worm wheel 206, and the second bevel gears 204 at both ends are driven to rotate through the worm wheel 206. At this time, the first bevel gear 202 is driven to rotate through the second bevel gear 204, so that the adjusting screw sleeve 201 rotates with the first bevel gear 202. When the adjusting screw sleeve 201 rotates, it drives the screw rod 209 to rise and fall, and drives the lower beam 210 to rise and fall through the screw rod 209, so that the traction wheel 301 follows the lower beam 210 to rise and fall, so as to adjust the suspension point stroke; S2. Sleeve the traction rope 302 on the traction wheel 301, and fix the carrying rope 310 in the reel 305, pull the traction rope 302 to drive the lightning arrester 303 to rise, and when the lightning arrester 303 rises and approaches the lower crossbeam 210, insert the synchronous frame 403 at the top of the lightning arrester 303, so that the synchronous frame 403 and the top of the lightning arrester 303 are engaged, and then insert the stud 405 at the bottom end of the rack 402 into the adjustment groove 404, and then insert the top end of the rack 402 into the protective cover 205, so that the top end of the rack 402 is engaged with the tightening gear 401, and then screw the fastening screw sleeve 406 upwards to fix the stud 405 and the synchronous frame 403 through the fastening screw sleeve 406; S3, pull the traction rope 302 again to make the lightning arrester 303 rise, at this time, the synchronous frame 403 drives the rack 402 to rise, the rack 402 drives the tightening gear 401 to rotate, and the rack 402 drives the reel 304 to rotate, so that the reel 305 rotates simultaneously with the reel 304, at this time, the load-bearing rope 310 is rolled up by the reel 305, and the traction rope 302 can be loosened at this time. At this time, the traction rope 302 is not subjected to force, and the lightning arrester 303 is vertically loaded by the reel 305 and the load-bearing rope 310, and the handle 208 is turned again to drive the lower beam 210 to rise. After adjusting the lower beam 210 to a suitable position, the traction rope 302 is pulled again to drive the lightning arrester 303 to rise, and the rack 402 is driven to rise while the lightning arrester 303 rises, so that the reel 305 reels the load-bearing rope 310 at the same time; S4. When the rack 402 rises with the lightning arrester 303, the reel 304 is driven to rotate by tightening the gear 401, and the ratchet 306 is driven to rotate. The ratchet 306 pushes the block 308 into the fixed box 307, and the block 308 is kept in contact with the ratchet 306 by the spring 309. When the traction rope 302 is released for the first time, the lightning arrester 303 has a tendency to move downward, but the block 308 is engaged with the ratchet 306, so that the ratchet 306 cannot be reversed, so that the reel 305 is fixed to achieve vertical load on the lightning arrester 303.

When the lightning arrester (303) rises close to the lower crossbeam (210), insert the synchronization frame (403) at the top of the lightning arrester (303) to make the synchronization frame (403) engage with the top of the lightning arrester (303). Then insert the stud (405) at the bottom of the rack (402) into the adjustment slot (404), and insert the top of the rack (402) into the protective cover (205) to make the top of the rack (402) engage with the tightening gear (401). Then turn the fastening sleeve (406) upward to fix the stud (405) and the synchronization frame (403) through the fastening sleeve (406). S3. Pull the towing rope (302) again to make the lightning arrester (303) rise. At this time, drive the rack (402) to rise through the synchronization frame (403), drive the tightening gear (401) to rotate through the rack (402), drive the reel (304) to rotate through the rack (402), so that the reel (305) rotates simultaneously with the reel (304). At this time, wind the bearing rope (310) through the reel (305). At this time, the towing rope (302) can be released. At this time, the towing rope (302) is not stressed, and the lightning arrester (303) is vertically loaded through the reel (305) and the bearing rope (310). Rotate the handwheel (208) again to drive the lower crossbeam (210) to rise. After adjusting the lower crossbeam (210) to the appropriate position, pull the towing rope (302) again to drive the lightning arrester (303) to rise, and drive the rack (402) to rise while the lightning arrester (303) rises, so that the reel (305) winds the bearing rope (310) at the same time. S4. When the rack (402) rises following the lightning arrester (303), drive the reel (304) to rotate through the tightening gear (401) and drive the ratchet (306) to rotate at the same time. The ratchet (306) pushes the block (308) into the fixed box (307), and the spring (309) makes the block (308) keep in contact with the ratchet (306). When the towing rope (302) is released for the first time, the lightning arrester (303) has a tendency to move downward, but due to the engagement of the block (308) and the ratchet (306), the ratchet (306) cannot reverse, so that the reel (305) is fixed to achieve vertical loading of the lightning arrester (303).
