A cleaning device for bridge expansion joints

Abstract

The invention discloses a cleaning device for a bridge expansion joint. The cleaning device comprises a left half-frame component (3), a right half-frame component (4), an upper elastic covering component (62) and a lower elastic covering component (61), wherein the upper elastic covering component (62) and the lower elastic covering component (61) are positioned between the left half-frame component (3) and the right half-frame component (4) and respectively used for covering expansion joints between the left half-frame component (3) and the right half-frame component (4) above the road surface of a bridge and under the road surface of the bridge; a first movable cleaning plate assembly (9) and a second movable cleaning plate assembly (8) arrayed in the front-rear direction are arranged in cavities (30,40) surrounded by the left half-frame component (3), the right half-frame component (4), the upper elastic covering component (62) and the lower elastic covering component (61).

Description

technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device for bridge expansion joints. Background technique [0002] Due to thermal expansion and contraction of bridge deck girders, expansion joint devices are often required. In the gap facing the road surface of the expansion joint device, in order to prevent the road debris from falling into the gap, an elastic covering plate, such as rubber products, is provided to cover it without affecting the function of the expansion joint and the driving performance. Expansion joint gap. [0003] However, such covering boards will inevitably be partially damaged during the driving process, and such damages are often difficult to be repaired in time, resulting in residues still falling into the expansion joints, thereby affecting the normal function of the expansion joints. [0004] And cleaning up the slag in these gaps will also waste manpower, and the cycle is longer. Contents of the ...
