Pulse gas shield welding device for processing wind power tower drum assembly

Abstract

The invention discloses a pulse gas shield welding device for processing a wind power tower drum assembly, and relates to the technical field of wind power tower drum processing. The problem that a common welding gun head needs to be carried by a worker for climbing welding is solved. The device specifically comprises a bottom plate, a third telescopic box is fixedly installed on one side of the top of the bottom plate through bolts, a rectangular hole is formed in the top of the third telescopic box, and first sliding rails are fixedly installed at the two ends of the inner wall of the third telescopic box through screws. According to the welding gun head lifting device, the first telescopic box, the second telescopic box, the third telescopic box, an air cushion pipe, a lifting pipe, an air pump and other devices are arranged, air is input into the air cushion pipe through the air pump, the air cushion pipe is sequentially expanded in the telescopic boxes, the telescopic boxes are extruded out, the lifting effect is achieved, the welding gun head is lifted to the position where a worker can take the welding gun head smoothly, and the welding gun head is convenient to use. And a worker does not need to carry the welding gun head device during climbing, so that the danger of the worker is avoided.

Description

technical field [0001] The present invention relates to the technical field of wind power tower processing, in particular to a pulse gas shielded welding device used for processing wind power tower components. Background technique [0002] The wind power tower is the tower pole of wind power generation, which mainly plays a supporting role in the wind power generation unit and absorbs the vibration of the unit at the same time. The production process of wind power towers is generally as follows: CNC cutting machine blanking, thick plates need to be beveled, plate rolling machine after forming, spot welding, positioning, welding of inner and outer longitudinal seams after confirmation, roundness inspection, If there is any problem, carry out secondary rounding. After the welding of the single-section cylinder is completed, use the hydraulic group to carry out pair spot welding on the roller frame, weld the inner and outer ring seams, check the straightness and other tolerance...

AI Technical Summary

Problems solved by technology

[0003] When processing the existing wind power tower components, due to the huge volume of the wind power tower, it is generally necessary to manually stand on a ladder or a professionally built shelf for welding operations when welding. Connection, when welding at a higher place, it is necessary to carry the welding torch head for welding. It is dangerous for the staff to climb and weld while carrying the torch head. Ordinary pulse gas shielded welding has certain limitations.
