Description

Technical Field

[0001] The utility model relates to the field of road maintenance, in particular to a bridge expansion joint cleaning device. Background Art

[0002] Bridge expansion joints refer to expansion joints that are usually set between two beam ends, between beam ends and abutments, or at the hinged position of the bridge to meet the requirements of bridge deck deformation. The expansion joints are required to be able to freely expand and contract in two directions parallel and perpendicular to the bridge axis, and to be firm and reliable. Existing bridge expansion joints are cleaned manually, which is not only inefficient, but also not clean enough. There are also dangers during the work process, so it is necessary to protect yourself at all times during the work. When performing manual cleaning, water guns are often used for flushing, which wastes water resources and it is difficult to completely clean impurities in the gaps. Therefore, a cleaning device for bridge maintenance is needed.

[0003] Patent No. CN219766109U in the prior art discloses a bridge expansion joint cleaning device, which also includes a shell and a transmission belt. A handrail is arranged on the outside of the shell. The output end of the motor is drivingly connected to the transmission belt. The transmission belt drives the second protrusion. A first protrusion is arranged on one side of the brush head. The first protrusion is connected to the second protrusion in mortise and tenon joints. A first cylindrical block is fixedly arranged on the other side of the brush head. The first cylindrical block is fixedly connected to the second cylindrical block. A disassembly device and a groove for accommodating the disassembly device are arranged near the brush head of the shell. The annular shell is surrounded by a bearing. The first protrusion, the first cylindrical block, the second cylindrical block and the axis of the bearing are in the same position. A fixing part is arranged between the annular shell and the shell, which is convenient for replacing the brush head, easy to operate and long working time of the device.

[0004] However, the patents under the existing technology have the following disadvantages:

[0005] (1) This utility model bridge expansion joint cleaning device is not provided with a component that can control the height of the cleaning wheel. The depth of the bridge expansion joint should be greater than or equal to half the thickness of the beam body, so as to ensure the normal operation of the expansion joint and the stability of the beam body. Therefore, the bridge expansion joint cleaning device needs to adjust the cleaning depth according to the depth of the expansion joint, otherwise it will affect the cleaning effect of the expansion joint.

[0006] (2) This utility model bridge expansion joint cleaning device is not equipped with a dust suction component. When cleaning the expansion joint, a large amount of dust will be generated. If the dust is not recovered, it will pollute the bridge road surface and affect the air quality of the working environment. Utility Model Content
