Bridge extension seam cleaning device capable of extending service life

Abstract

Disclosed is a bridge extension seam cleaning device capable of extending service life. The cleaning device comprises a left-half framework (3), a right-half framework (4), and an upper elastic covering element (62) as well as a lower elastic covering element (61) that are located between the left-half framework (3) and the right-half framework (4) and are respectively used for covering the left-half framework (3) as well as the right-half framework (4) above and below the road surface of the bridge. A first movable cleaning plate component (9) and a second movable cleaning plate component (8) are arranged along the front-back direction inside cavities (30, 40) encircling by the left-half framework (3), the right-half framework (4), the upper elastic covering element (62) and the lower elastic covering element (61).

Description

Technical field [0001] The invention relates to a cleaning device, in particular to a bridge expansion joint cleaning device which can extend the service life. Background technique [0002] The bridge deck girder often needs expansion joints due to thermal expansion and contraction. In the gap of the expansion joint device facing the road, in order to prevent road debris from falling into the gap, an elastic covering plate, such as a rubber product, is provided to cover without affecting the function of the expansion joint and without affecting the driving performance. Expansion joint gap. [0003] However, it is inevitable that this kind of cover plate will be partially damaged during the driving process. Such damage is often difficult to repair in time, resulting in residues still falling into the expansion joint and affecting the normal function of the expansion joint. [0004] And cleaning up the slag in these crevices will waste manpower, and the cycle is longer. Summary of t...
