A bridge with a self-cleaning expansion joint device driven by a motor

Abstract

Disclosed is a bridge provided with an automatic cleaning type expansion joint device driven by an electric motor. The automatic cleaning type expansion joint device includes a left half frame (3), a right half frame (4), and an upper elastic covering part (62) and a lower elastic covering part (61) which are located between the left half frame (3) and the right half frame (4), and are respectively used for covering expansion joints between the left half frame (3) and the right half frame (4) on a road surface and under the road surface of the bridge. Cavities (30, 40) surrounded by the left half frame (3), the right half frame (4), the upper elastic covering part (62), and the lower elastic covering part (61) are provided with a first movable cleaning plate assembly (9) and a second movable cleaning plate assembly (8) therein, wherein the first movable cleaning plate assembly (9) and the second movable cleaning plate assembly (8) are arranged in the anteroposterior direction.

Description

Technical field [0001] The invention relates to a bridge with expansion joints, in particular to a bridge with an automatic cleaning type expansion joint device driven by a motor. 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 surface, in order to prevent road debris from falling into the gap, an elastic cover plate, such as rubber products, is provided to cover without affecting the function of the expansion joint and without affecting the driving performance. Expansion joint gap. [0003] However, this kind of cover plate will inevitably 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. ...
