A cleaning machine that adapts to different bridge expansion joints with repulsive force and spring characteristics

Abstract

The invention discloses a cleaning machine adapted to different bridge expansion joints with repulsive force and spring characteristics. Its structure includes handrails, cleaning devices, a body, walking wheels, and grooves. The four corners of the bottom surface of the body are all mechanically connected. There are walking wheels. Compared with the prior art, the beneficial effect of the present invention is that it can not only adapt to bridge expansion joints of different depths, but also adapt to bridge expansion joints of different widths. Based on the principle of magnetism, opposite-sex magnets have relative repulsion, The magnitude of the repulsive force is proportional to the magnitude of the current, and the distance between the two cleaning discs can be adjusted through the sliding rheostat to adapt to the bridge expansion joints of different widths. The spacing changes equidistantly, so the spacing between the pressing rollers also changes equidistantly, so that the stretchable elastic brush can be stretched, so that the stretchable elastic brush can better fit and contact with the bridge expansion joint, which is convenient for the bridge expansion joint. Clean up the underside.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a cleaning machine which adapts to expansion joints of different bridges by virtue of repulsive force and spring characteristics. Background technique [0002] Due to the falling of foreign objects while the vehicle is driving on the bridge and the excess concrete in the beam end construction, it is easy to block the expansion joints of the bridge, which will affect the free expansion and contraction of the bridge, so it is necessary to clean the expansion joints of the bridge. [0003] Due to imperfect technology, most of the existing expansion joint cleaning devices can only be adjusted in height, and can only be adapted to bridge expansion joints of different depths, and the width of bridge expansion joints is also different, so they cannot be adapted to bridge expansion joints of different widths. If there are too many gaps, the cleaning will not be thorough enoug...

AI Technical Summary

Problems solved by technology

[0003] Due to imperfect technology, the existing cleaning devices for expansion joints can only be adjusted in height, and can only be adapted to bridge expansion joints of different depths, and the width of bridge expansion joints is also different, so they cannot be adapted to bridge expansion joints of different widths. If there are too many seams, the cleaning will not be thorough enough and multiple cleanings will be required, resulting in low cleaning efficiency, heavy workload and long cleaning time.
