Problems solved by technology
[0003] The lengths of steel pipes supported by welding brackets are different. In order to support longer steel pipes, some welding brackets have two sets of support wheels arranged at intervals, but the distance between the two sets of support wheels cannot be adjusted, making it difficult to support both long steel pipes and short ones. steel pipe

The invention discloses a steel pipe welding supporting device, and relates to the technical field of large-diameter steel pipe welding, and provides a steel pipe welding supporting device suitable for supporting steel pipes with different lengths. The steel pipe welding supporting device comprises an adjustable connecting structure and two welding supports. The adjustable connecting structure comprises a chain and two adjustable connecting assemblies arranged in the length direction of the welding support in a spaced mode. Each adjustable connecting assembly comprises an adjusting sleeve, a chain wheel and two screws, wherein the two screws are coaxially arranged and each connected with one welding support, the two screws are opposite in thread rotating direction, the adjusting sleeve isarranged between the two screws and connected with the two screws in a threaded mode, a wrench connecting structure is arranged outside the adjusting sleeve, and the chain wheel is arranged outside the adjusting sleeve in a sleeving mode and connected with the adjusting sleeve. The chain is connected with the chain wheels of the two adjustable connecting assemblies. The distance between the two welding supports can be simply and conveniently adjusted by rotating the adjusting sleeves; the steel pipe welding supporting device can be suitable for supporting steel pipes with different lengths.
Description
technical field [0001] The invention relates to the technical field of large-diameter steel pipe welding, in particular to a steel pipe welding support device. Background technique [0002] Welding brackets are often used for butt welding of large diameter steel pipes. The welding stand is movable on guide rails and has at least two supporting wheels. When welding, put the two steel pipes on the two supporting wheels of the welding bracket respectively, move the welding bracket so that the two steel pipes are facing each other, and then the welding can be carried out; the rotation of the supporting wheels can drive the steel pipes to rotate so as to weld the steel pipes for a circle. [0003] The lengths of steel pipes supported by welding brackets are different. In order to support longer steel pipes, some welding brackets have two sets of support wheels arranged at intervals, but the distance between the two sets of support wheels cannot be adjusted, making it difficult t...
