In this configuration, the screw rod 502 is locked by the friction between the rubber pad 503 and the grinding wheel 501.

[0052] The implementation principle of the conductor installation tool for metal-enclosed busbar of this embodiment is as follows: the front roller 203 is in the open state, the roller 104 is in the retracted state, and the device as a whole is slid along the inner wall of the metal pipe through the roller 203. When it slides to an appropriate position, the electric push rod 311 is remotely started, and the electric push rod 311 extends and resists the tension spring 310 and the second telescopic rod 309, thereby driving the fan gear 302 to rotate, the fan gear 302 drives the first swing rod 304 to rotate, and the first swing rod 304 drives the second swing rod 305 through the third ring 303. The second swing rod 305 is lifted upward under the guidance of the guide groove 307, so that the third ring 303 is lifted, the third ring 303 drives the first ring 206 to rise, the first ring 206 drives the connecting plate 205 to rise, the connecting plate 205 drives the connecting block 204 to rise, the connecting block 204 drives the movable rod 201 to rise, the movable rod 201 drives the connecting shaft 202 to rise, the connecting shaft 202 drives the roller 203 to leave the ground, at this time, the bottom of the base 100 contacts the ground and is kept fixed by friction, and the sector gear 302 rotates while passing The meshing drives the first gear 400 to rotate, and the first gear 400 drives the second gear 404 to rotate through the meshing, and the second gear 404 drives the locking block 405 to rotate, so that the locking block 405 is staggered with the baffle 402, so that the mounting plate 102 is unlocked, and one of the locking blocks 405 rotates while pressing against one end of the support plate 505, and the support plate 505 moves, and the movement of the support plate 505 drives the support block 504 to move, and the support block 504 drives the rubber pad 503 to move and disengage from the grinding wheel 501, at this time, the screw rod 502 is unlocked, and the support plate 505 moves while driving The movable guide slope 507 moves and makes the guide slope 507 staggered with the guide block 509. At this time, the guide block 509 can move to the top of the support plate 505. The support plate 505 is kept in a fixed position under the action of the locking block 405 and the slot 506. The motor 500 is started, and the motor 500 rotates to drive the grinding wheel 501 and the screw rod 502 to rotate. The screw rod 502 drives the mounting plate 102 to rise, so that the roller 104 rises and supports the conductor. The conductor is mounted on the roller 104 to avoid contact with the inner wall of the metal pipe, thereby preventing the conductor from rubbing against the metal pipe.

The motor 500 is started in the reverse direction, and the motor 500 drives the mounting plate 102 to descend through the screw rod 502, and the mounting plate 102 is When it descends, it drives the positioning rod 508 to descend, and the positioning rod 508 drives the guide block 509 to descend. The guide block 509 drives the support plate 505 to move by abutting against the guide inclined surface 507. At this time, the card slot 506 is disengaged from the locking block 405. The locking block 405 is reset under the tension of the tension spring 310 and locks the baffle 402 again. At the same time, the elastic force of the spring 512 pushes the sleeve 510, so that the support plate 505 is reset. The support plate 505 drives the rubber pad 503 to reset through the support block 504, and the friction between the rubber pad 503 and the grinding wheel 501 is used to lock the screw rod 502.

[0054] When the locking block 405 is reset, the sector gear 302 rotates accordingly and drives the second swing rod 305 to reset through the first swing rod 304. The second swing rod 305 descends under the action of the guide groove 307 and drives the roller 203 to descend. At this time, the roller 203 plays a supporting role and can be moved by the roller 203.
