[0007] In order to solve the above technical problems, the utility model provides a technical scheme that a steel pipe tower convenient to maintain, comprising a steel pipe tower, a cross arm arranged at the top of the steel pipe tower, and a rotatable maintenance platform arranged at the top of the steel pipe tower.

[0008] The maintenance platform comprises a bearing sleeved on the steel pipe tower, an L-shaped plate hingedly arranged on the bearing and capable of being accommodated in the steel pipe tower, and elongated plates hingedly arranged on both sides of the L-shaped plate and capable of being folded and accommodated.

[0009] As an improvement, ears are respectively arranged on the bearing and the L-shaped plate, and the ears are connected through a pin.

[0010] As an improvement, a cylinder is arranged on the bearing, a lug is arranged on the L-shaped plate, and a bolt is arranged on the lug and fastened and connected with the cylinder through the lug.

[0011] As an improvement, screw holes are arranged on the L-shaped plate and the elongated plates and matched with each other, and a fixing bolt is arranged in the screw holes and capable of fixing the L-shaped plate and the elongated plates together.

[0012] (III) beneficial effects

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] 1. The rotating shaft allows the maintenance platform to rotate on top of the steel pipe tower, facilitating construction work from different locations;

[0015] 2. The L-shaped plate and the bearing are connected by an ear hinge. After construction, the maintenance platform can be folded up and placed close to the steel pipe tower. The bolts and screws are matched to fix the maintenance platform and keep it level, making it easy for personnel to stand.

[0016] 3. The extension plate can increase the area of ​​the maintenance platform where personnel can stand, and the fixing bolts can make the extension plate fit and fix it to the L-shaped plate. Attached Figure Description
