Description

Technical Field

[0001] The utility model belongs to the technical field of ring welding devices for wind power towers, and in particular relates to a ring welding device for wind power towers. Background Art

[0002] A wind turbine tower is a tower pole for wind power generation. It mainly plays a supporting role in a wind turbine generator set and absorbs the vibration of the set. Generally, a wind turbine tower is composed of three or more tower shells. Each tower shell is welded together by several shell sections. The welds between the shell sections are annular welds, so they are called ring welds. Before welding, the wind turbine tower needs to be placed on a ring welding device, and the wind turbine tower shell is supported by the ring welding device.

[0003] Disclosed is a ring welding device for a wind turbine tower, with the publication number CN220330433U, and the beneficial effects are as follows: a hand wheel is rotated by manpower to rotate, so that the hand wheel, screw rod, turntable, pressing frame, through groove, limit rod, limit block, and stabilizing frame cooperate with each other to achieve a clamping and fixing effect, thereby avoiding shaking of the wind turbine tower during welding of the wind turbine tower, thereby achieving the effect of improving the stability of the ring welding device; the wind turbine tower is placed on a placement frame, so that the placement frame, stabilizing frame, buffer groove, sliding plate, spring, and sliding rod cooperate with each other to achieve a buffering effect, and the placed wind turbine tower can be effectively protected, thereby achieving the effect of improving the protectiveness of the ring welding device.

However, in actual use, since the overall tower is annular, it is difficult to weld it. The limited processed parts are welded by adjusting welding, and the overall welding effect is poor. Based on this, a ring welding device for a wind turbine tower is proposed to solve the above problem. Utility Model Content
