Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure bridge processing and production, and particularly relates to a processing device for steel structure bridges. Background Art

[0002] A steel structure is a structure composed of steel materials and 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, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. When used in the bridge field, it is called a steel structure bridge. The steel structure bridge has the advantage of a short construction period because all structural components are prefabricated in the factory and can be hoisted to the site. Workers in the factory weld the plates into the required bridge prefabricated parts according to the drawings. Among them, the processing technology of welding long strip plates into boxes is very common. However, due to the long length of the box-shaped steel structure bridge, when welding or spraying anti-corrosion paint, multiple lifting devices are required to lift the box girder, turn it in the air, and then place it on the support frame to weld and spray anti-corrosion paint on the box-shaped steel structure bridge. This requires the cooperation of a large number of workers and lifting devices. Moreover, when the steel structure bridge is turned over, there are adverse factors such as deformation of the steel structure bridge caused by lifting and welding joint detachment. Therefore, in the prior art, due to the long length of the steel structure bridge, it is inconvenient to turn over during production, resulting in the need for a large number of workers and low production efficiency. Summary of the Utility Model
