Description

Technical Field

[0001] The utility model relates to the technical field of silo manufacturing, in particular to a welding auxiliary device for the flange edge of a silo wall. Background Art

[0002] Currently, existing large silos are all composed of multiple silo walls disassembled from the whole silo body, and the silo walls are connected into a whole by welding flanges. At present, when welding existing silo walls, the silo walls are first clamped on a support frame, and then the flange edges are manually welded to both sides of the silo walls. Since the support frame is fixed, it is rather inconvenient when welding the flange edges, which not only increases the welding labor intensity but also has a low welding efficiency.

[0003] Therefore, it is necessary to design a welding auxiliary device for the flange edge of a silo wall to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a welding auxiliary device for the flange edge of a silo wall aiming at the deficiencies of the prior art.

[0005] The technical solution of the utility model is: a welding auxiliary device for the flange edge of a silo wall, which includes a base and a support frame rotatably connected to the base; a driving mechanism for driving the support frame to rotate is arranged on the base; a plurality of fixed sleeves are evenly distributed on both sides of the support frame.

[0006] The driving mechanism includes a driving motor fixed to the bottom of the base and a mounting shaft rotatably connected to the top of the base; a driving sprocket is fixed on the output shaft of the driving motor; a driven sprocket is fixed on the mounting shaft; the driving sprocket and the driven sprocket are connected by a chain; first connection flanges are arranged at both ends of the mounting shaft; second connection flanges respectively fixed to the two first connection flanges are arranged on the support frame.

[0007] A tensioning sprocket for tensioning the chain is fixed on the base.

[0008] The top of the support frame is arc-shaped.

[0009] Avoidance spaces are respectively arranged at the front side and the rear side of the support frame corresponding to the base.

[0010] Adopting the above technical solution, the utility model has the following beneficial effects: the utility model rotatably arranges a support frame on the base, and drives the support frame to turn over through the driving mechanism, so that the flange edges on both sides of the silo wall positioned on the support frame are adjusted to the optimal welding angle, thus making the welding more convenient, reducing the manual labor intensity and improving the welding efficiency.
