The right end of the first screw rod 3 passes through the longitudinal fixed plate 2 through the bearing and is connected to the output end of the first servo motor 4, and the first screw rod 3 is threadedly connected to the push plate 9. By starting the first servo motor 4, the first screw rod 3 is rotated forward or reversely. The push plate 9 threadedly connected to the outer side of the first screw rod 3 has the function of horizontal translation, so that the right limit rod 6 of the grinding wheel 5 can be flexibly moved, thereby facilitating the disassembly and assembly of the grinding wheel 5. When the grinding effect of the grinding wheel 5 is reduced due to a long time, a new grinding wheel 5 can be replaced in time. A slider 10 is installed on the top of the push plate 9, and a slide groove 11 is arranged on the outer side of the slider 10, and the push plate 9 is slidably connected to the bottom of the movable top plate 1 through the slider 10 and the slide groove 11. Under the mutual cooperation of the slider 10 and the slide groove 11, the push plate 9 is horizontally translated left and right along the lower surface of the movable top plate 1. The contact surface between the slider 10 and the slide groove 11 is smooth, which makes the push plate 9 more flexible when moving;

[0024] The base 12 is arranged parallel to the lower part of the grinding wheel 5, and the left and right sides of the upper surface of the base 12 are welded with a longitudinal frame 13, a long slot 14 is opened inside the longitudinal frame 13, and a second screw rod 15 is installed inside the long slot 14, the top of the second screw rod 15 is connected to a second servo motor 16, a gear 17 is installed on the outer side of the top of the second screw rod 15, and a chain 18 is meshed and connected to the outer side of the gear 17, and the two second screw rods 15 are connected by the gear 17 and the chain 18. Under the mutual cooperation of the gear 17 and the chain 18, the two second screw rods 15 maintain the same movement frequency, through The second servo motor 16 can simultaneously drive the two second screw rods 15 to rotate, the outer side of the second screw rod 15 is threadedly connected with a movable block 19, and a controller 20 is installed on the right side of the vertical frame 13. The left and right ends of the movable top plate 1 are fixed with movable blocks 19, and the movable blocks 19 are threadedly connected with the second screw rod 15, and the outer surface of the movable block 19 is in contact with the inner wall of the long groove 14. Through this setting, the movable block 19 has a lifting function, thereby driving the movable top plate 1 and the grinding wheel 5 to rise and fall together, which is convenient for adjusting the height of the grinding wheel 5 according to the height of the staff, avoiding the staff from bending over for a long time.

[0025] Working principle: When in use, first adjust the height of the grinding wheel 5 according to the height of the staff. When the staff is taller, start the second servo motor 16 through the controller 20. Under the cooperation of the gear 17 and the chain 18, the two second screw rods 15 are reversed at the same time, and the movable block 19 threadedly connected to the outer side of the movable block 19 rises. Since the movable block 19 is fixed to the movable top plate 1, the movable top plate 1 and the grinding wheel 5 rise. The staff does not need to bend down when using the grinding wheel 5 to grind the iron tower parts. When the staff is shorter, control the second screw rod 15 to reverse so that the movable top plate 1 and the grinding wheel 5 are lowered to the appropriate position. The surface of the grinding wheel 5 is easily worn due to long-term grinding of the tower parts, so the grinding wheel 5 needs to be replaced regularly. The first servo motor 4 is started through the controller 20, so that the first screw rod 3 is reversed, and the push plate 9 threadedly connected to the outer side of the first screw rod 3 moves to the right, so that the limit rod 6 inserted into the right side of the grinding wheel 5 is pulled out, and then the old grinding wheel 5 is removed and replaced with a new grinding wheel 5. When replacing the new grinding wheel 5, the left limit groove 7 of the grinding wheel 5 needs to be aligned with the left limit rod 6 and inserted. The first servo motor 4 is started again to start the first screw rod 3 to rotate forward, and the push plate 9 is inserted into the right side of the grinding wheel 5 with the right limit rod 6, so that the disassembly and assembly of the grinding wheel 5 is realized.

[0026] The device is controlled automatically by the controller 20. The control circuit of the controller 20 can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field. Therefore, the control method and circuit connection of the device will not be explained in detail.
