Description

Technical Field

[0001] The utility model relates to the technical field of bridge steel structure processing, in particular to a bridge steel structure surface polishing machine. Background Art

[0002] The steel structure of a bridge is made of steel. Compared with traditional concrete materials, steel has higher strength and toughness. Therefore, the use of steel structure of a bridge can greatly improve the load-bearing capacity of the bridge, increase the load bearing capacity of the bridge, and reduce the deadweight load of the bridge, thereby achieving better economic benefits. During the processing of the steel structure of a bridge, there will be burrs on the surface of the steel structure of the bridge to varying degrees, which need to be further processed. Usually, a bridge steel structure surface polishing machine is used to remove the burrs.

[0003] The existing bridge steel structure surface polishing machine uses a motor to drive the grinding wheel and polishing wheel to rotate, then uses the grinding wheel to grind the surface of the bridge steel structure, and then uses the polishing wheel to polish the material, making the surface of the produced bridge steel structure smoother;

[0004] Existing bridge steel structure surface polishing machines usually use one drive structure to simultaneously drive the grinding and polishing components. When the bridge steel structure is being ground or polished, the processing component on the other side is still running, which poses certain safety hazards. Therefore, we propose a bridge steel structure surface polishing machine. Utility Model Content
