Road and bridge self-propelled expansion joint cleaning device for municipal engineering

Abstract

The invention discloses a road and bridge self-propelled expansion joint cleaning device for municipal engineering, and relates to the technical field of engineering construction. The road and bridge self-propelled expansion joint cleaning device comprises a push rod, a push plate is hinged to the bottom of the push rod, and a cleaning self-collecting mechanism is arranged in the push plate. By arranging the cleaning and self-collecting mechanism, along with rolling of the rolling wheel, residues adhered to the outer wall of the rolling wheel can be rotated to the position, making contact with the outer wall of the rolling wheel, in the sliding block and scraped into a groove in the sliding block by the inner wall of the sliding block, so that centralized collection is conducted, and automatic collection and arrangement of the residues are completed; when a push plate is pushed to extrude a roller to compress a road surface, the roller synchronously drives a sliding block to upwards push and extrude an elastic plate through a rotating rod to deform the elastic plate, and extrudes air in a sliding groove to be sprayed out through an air groove to blow away residues in the expansion joint, and then the residues are adhered along with rolling of the roller, so that the cleaning efficiency of the interior of the expansion joint is improved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a self-propelled expansion joint cleaning device for roads and bridges used in municipal engineering. Background technique [0002] Building expansion joints, also known as expansion joints, refer to a structural joint set at an appropriate position along the direction of the construction joints of buildings or structures in order to prevent structural cracks or damage to the structure due to climatic temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, roofs (except wooden roofs) into two independent parts, so that the buildings or structures can be horizontally stretched along the long direction. Expansion joints on bridge roads have accumulated a large amount of gravel and dust inside the expansion joints for many years, which seriously affects the expans...

AI Technical Summary

Problems solved by technology

After years of expansion joints on bridge roads, a large amount of gravel and dust have accumulated inside the expansion joints, which seriously affects its expansion effect. At present, when cleaning the expansion joints, it is often necessary to clean the expansion joints again. Sweeping and collecting, and when sweeping and collecting, often the residue and dust are easy to fall into the seam again, there are many expansion joints, and the work efficiency of cleaning expansion joints is slow
