Description

Technical Field

[0001] The invention relates to the technical field of bridge maintenance, and in particular to a highway bridge expansion joint cleaning device. Background Art

[0002] The expansion joint of a highway bridge is an important part of the bridge structure. Its main function is to adapt to the expansion and contraction deformation of the bridge caused by temperature changes, vehicle loads and other factors. However, the expansion joints are prone to accumulate dust, sand, metal debris and other garbage. If they are not cleaned for a long time, the expansion joints will be blocked, affecting the normal expansion and contraction function of the bridge and even endangering the safety of the bridge. Traditional cleaning methods usually rely on manual labor, which is inefficient, labor-intensive, and prone to dust, causing adverse effects on the environment and the health of the cleaning personnel.

[0003] In the prior art, although there are some mechanical cleaning devices, they often have single functions, such as only vacuuming or sweeping functions, which makes it difficult to effectively deal with the complex situation of various types of garbage in the expansion joints. In addition, these devices also have deficiencies in mobility and operational flexibility, and are difficult to adapt to the actual use needs of different bridges. Therefore, there is an urgent need for a highway bridge expansion joint cleaning device that integrates multiple functions, is efficient, environmentally friendly, convenient and practical to solve the above problems.
