The working principle of the invention is as follows: the first rotating shaft 3 is rotated by a rotating motor, the first rotating shaft 3 drives the rotating wheel 4 to rotate, so that the platform moves, meanwhile, the first rotating shaft 3 drives the worm 9 to rotate by the turbine 5, the worm 9 drives the incomplete external gear 10 and the incomplete internal gear 39 to rotate, firstly, the incomplete external gear 10 is meshed with the first gear 11, the incomplete internal gear 39 is disengaged from the first gear 11, the incomplete external gear 10 drives the first gear 11 to rotate, the first gear 11 drives the first connecting rod to rotate by the second rotating shaft 12, the first connecting rod drives the cleaning brush 13 to rotate, the cleaning brush 13 is enabled to sweep garbage close to the dust collection pipe 14, then the incomplete external gear 10 is disengaged from the first gear 11, the incomplete internal gear 39 is meshed with the first gear 11, the incomplete internal gear 39 drives the first gear 11 to rotate, the cleaning brush 13 reversely rotates, and thus the repeated positive and negative rotation of the cleaning brush 13 is enabled, the cleaning efficiency of the road surface in the tunnel is improved, when the high-altitude operation is needed, the handle 27 is rotated, the rotating rod 26 drives the first moving block 28 to move through the threaded part, the first moving block 28 drives the second connecting rod 17 to move downwards through the cooperation of the connecting seat 31 and the seventh connecting rod 32, the second connecting rod 17 drives the supporting column 16 to move downwards, the foot seat is abutted against the ground, the rotating wheel 4 is far away from the ground, at the moment, the first moving block 28 is separated from the threaded part, the abutting block 34 is abutted against the second moving block 29, the second moving block 29 is matched with the threaded part on the rotating rod 26, the second moving block 29 drives the L-shaped rod 30 to move, the L-shaped rod 30 drives the sliding seat on the first sliding rail 19 to move, the lower end of the fourth connecting rod 22 moves towards the direction close to the L-shaped rod 30, under the action of the sixth connecting rod and the fifth connecting rod 24, the upper end of the fourth connecting rod 22 moves towards the direction far away from the L-shaped rod 30, so that the lifting platform 18 moves upwards, when the high-altitude operation is finished, the handle 27 is reversely rotated, the second moving block 29 drives the L-shaped rod 30 to move close to the first moving block 28, the lifting platform 18 moves downwards, when the second moving block 29 is separated from the threaded part, the second moving block 29 is in contact with the contact block 34, the contact block 34 pushes the first moving block 28 to be matched with the threaded part through the second telescopic rod 33, the first moving block 28 drives the second connecting rod 17 to move upwards through the matching of the connecting seat 31 and the seventh connecting rod 32, so that the support column 16 moves upwards, the rotating wheel 4 is in contact with the ground, and the connecting box 1 can move.
In conclusion, through the cooperation of runner 4, brush cleaner 13 and support column 16, realize effectively improving the efficiency of cleaning and improve the advantage of the security of aerial work.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
