[0002] Polygonal steel tube towers are generally conical structures with small upper diameter and large lower diameter. They have reasonable force and have outstanding advantages such as beautiful appearance, convenient construction, small footprint, and less operation and maintenance workload. They are widely used as cable supports for transmission lines or as communication towers at home and abroad, and have good development prospects.

[0003] In the production process of multi-faceted steel tube towers, two or more steel plates are generally bent by a bending machine and then welded together.

[0004] After the welding between the steel plates of the existing multi-faceted steel tube tower is completed, burrs are prone to occur at the welds. Due to the irregular structure of the multi-faceted steel tube tower, it is difficult to uniformly grind its welds through ordinary automatic grinding equipment. Therefore, it is often done manually, which consumes manpower and time while reducing processing efficiency. In view of this, we propose an automatic grinding device for the welds of multi-faceted steel tube towers. Utility Model Content
