Problems solved by technology

Steel members are often deformed after welding and need to be corrected. After welding and assembly of steel members, not only the number of welds is large, but also the welds are long and straight. The workload of correction is very heavy. For example, there are a large number of welds on bridge steel box girders. U-rib welding, traditional weld seam calibration, usually the workers hold the flame calibration gun to calibrate the weld seam one by one, not only the calibration work efficiency is low, the labor intensity of the workers calibration is high, but also the calibration effect is easily affected by human operation errors

Abstract

The invention discloses a walking type flame correction device, and solves the technical problems that in the prior art, welding seam correction is conducted by means of manual handheld equipment, the correction labor amount of workers is large, and correction errors are large due to manual operation. The walking type flame correction device comprises a walking trolley, a plurality of flame nozzles and a gas conveying mechanism, wherein the flame nozzles are arranged on the walking trolley and used for correcting welding seams, and the gas conveying mechanism is arranged on the walking trolley, connected with an external gas source, connected with the flame nozzles and used for supplying gas to the flame nozzles. The walking type flame correction device is simple in structure, scientific and reasonable in design and convenient to use. The walking trolley is adopted for driving the flame nozzles to conduct flame correction on multiple welding seams at the same time, so that correction efficiency is high, operation is stable, correction errors can be effectively reduced, and correction quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of steel structure assembly equipment, and in particular relates to a walking flame correcting device. Background technique [0002] Due to its light weight, high strength and easy construction, steel structures are widely used in bridges, large factory buildings, venues, super high-rises and other fields. They are mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components or components are usually connected by welds, bolts or rivets. Steel members are often deformed after welding and need to be corrected. After welding and assembly of steel members, not only the number of welds is large, but also the welds are long and straight. The workload of correction is very heavy. For example, there are a large number of welds on the bridge steel box girder U-rib welding, traditional weld seam calibration, generally requires workers to hold...
