Description

Technical Field

[0001] The utility model relates to the field of beverages, in particular to a coating device for steel structures of road bridges. Background Technique

[0002] The steel structure project is a structure mainly made of steel, which is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates. Welds, bolts or rivets are usually used to connect each component or part. The characteristics of steel are high strength, light self-weight, good overall rigidity and strong deformation ability. Therefore, it is particularly suitable for building large-span, ultra-high and ultra-heavy buildings. Therefore, steel structures are common in bridge construction. Since bridges are often located above rivers and the air is relatively humid, anti-corrosion treatment is required, and spraying anti-corrosion paint is one of the more common anti-corrosion methods.

[0003] The spraying device of the existing coating device for steel structures of road bridges sprays paint on the surface of the steel structure by using a nozzle. For example, a coating device for steel structures of road bridges with the publication number of CN220371333U constructs a coating device for steel structures of road bridges by setting a processing box, an adjusting mechanism, a first motor, an electric push rod, a clamping mechanism, a steel structure, a paint box, a discharge nozzle and a paint pump. Among them, through the setting of the adjusting mechanism, the paint box, the discharge nozzle and the paint pump can be driven to move left and right, so as to expand the spraying area. The setting of the clamping mechanism can clamp the steel structure. Through the setting of the electric push rod, steel structures of different lengths can be adapted. The setting of the first motor can drive the steel structure to rotate, further improving the spraying effect. After the nozzle sprays one side of the surface of the steel structure, it is necessary to adjust the rotation of the steel structure by the motor to spray the other side, and the steel structure needs to be rotated multiple times for adjustment. The operation steps are relatively cumbersome, and the two side surfaces of the steel structure are clamped and blocked by the clamping plates, and it is difficult to spray paint on the clamped part.
