Bridge expansion joint cleaning device

Abstract

The invention relates to the technical field of bridge cleaning devices, in particular to a bridge expansion joint cleaning device. The device comprises a cleaning cart, the cleaning cart is provided with rollers, a push plate and a push rod, the push plate comprises a cleaning rod, a supporting table, a dust suction mechanism, an air blower and a storage battery, the cleaning rod comprises a supporting plate, a rod body and a brush frame, the supporting plate is slidably connected with the supporting table, the supporting plate is provided with a rotating motor, the output end of the rotating motor is connected with the rod body, the bottom end of the supporting table is provided with a penetrating channel matched with the rod body, and the rod body is movably connected with the brush frame; and the dust suction mechanism comprises a dust suction box body and a dirt suction pipe, and the air blower is provided with an air outlet pipe and a guide rod. The descending brush frame extends into the bridge expansion joint, the dirt suction port of the dust suction mechanism is aligned to the direction of the brush frame, the brush frame stirs dirt in the bridge expansion joint, the stirred dirt is sucked into the dust suction box body by the dirt suction scraper, the efficiency of removing the dirt in the bridge expansion joint is greatly improved, and an asphalt structure of the expansion joint cannot be damaged.

Description

technical field [0001] The invention relates to the technical field of bridge cleaning devices, in particular to a bridge expansion joint cleaning device. Background technique [0002] In order to meet the deformation requirements of the bridge deck, expansion joints are usually set between the two girder ends, between the girder end and the abutment, or at the hinged position of the bridge. Displacements and linkages between structures. The bridge expansion joints are required to be free to expand and contract in two directions parallel and perpendicular to the bridge axis, firm and reliable, and the vehicles should run smoothly without sudden jumps and noises; they must be able to prevent rainwater, garbage and soil from infiltrating and blocking. Where expansion joints are set, railings and bridge deck pavement must be disconnected. [0003] Bridge expansion joints are easy to accumulate particulate matter and other dirt, especially in areas with lack of vegetation and ...

AI Technical Summary

Problems solved by technology

Particles or dirt are easy to fall directly into the bottom of the gap. The falling of these particles or dirt will affect the normal use of the bridge expansion joints. It is necessary to clean up the particles or dirt in the expansion joints regularly, but most of the bridge expansion joints have small gaps. , and has a certain depth, it is difficult to clean effectively

Even if the rod body is used to extend into the expansion joint of the bridge, since the expansion joint is coated with asphalt, when the rod body picks up the dirt adhering to the asphalt, it is easy to damage the asphalt structure of the expansion joint
