Problems solved by technology

[0004] Traditional rotary tires are fixed rotary tires, which are suitable for limited changes in pipe diameters. For large-diameter pressure pipes, fixed rotary tires have problems such as unstable placement, irregular rotation, affected welding quality, low welding efficiency, and high rework rate.

Embodiment Construction

[0018] Now in conjunction with accompanying drawing, technical scheme of the present invention is described further:

[0019] The pipe circular seam welding movable tire of the present invention is mainly composed of a base 1, two rows of runners 3 and a frame support.

[0020] The two rows of runners 3 are fastened on the base 1 with bolts through the wheel frame 6. Since the row spacing of the two rows of runners 3 needs to be adjusted, the wheel frames 6 of a row of runners 3 are tightened on the base with bolts. 1 for a fixed position (eg figure 2 The left row of runners 3), the other row of runners 3 (such as figure 2 The right row of runners 3) is tightened on the position of the adjustable distance of the base 1 with bolts. The usual practice is to correspond to a row of runners 3 that are movable. There are multiple sets of screw holes on the base 1. The bolts on the wheel frame 6 at different positions are matched and installed; the power of the present invention ...

Abstract

The invention discloses a movable turner for welding a circular seam of a pipeline. The movable turner comprises a turning mechanism which is arranged on a substrate to support and drive the pipeline to rotate, the turning mechanism consists of two rows of turning wheels with an adjustable space between rows, one row of turning wheels are fixedly arranged, the other row of turning wheels are movably arranged, a fixedly arranged turning wheel is used as a driving wheel, and the driving wheel is connected with a driving motor through a speed reducer; and the base is also provided with a frame-type bracket which is higher than the pipeline, and a welding platform is arranged on the top of the frame-type bracket corresponding to the circular seam of the pipeline. According to the movable turner for welding the circular seam of the pipeline, the problems of position adjustment and rotation in a pipeline welding process are solved, the welding is convenient for a welder, and the welding quality can also be guaranteed.

Description

(1) Technical field: [0001] The invention relates to a welding auxiliary device, in particular to a movable rotary tire for pipe circular seam welding. (2) Background technology: [0002] Radiographic flaw detection is required for the quality inspection of large-diameter pressure pipe girth welding, so higher requirements are put forward for the welding quality of the weld. [0003] The circular seam welding of large-diameter pressure pipes is conventionally performed by rotary welding, that is, the pipe is placed on a rotary tire, and the rotary tire rotates to drive the pipe to rotate, and the welder performs flat welding on the top of the pipe to the circular seam. [0004] Traditional rotary tires are fixed rotary tires, which are suitable for limited changes in pipe diameters. For large-diameter pressure pipes, fixed rotary tires have problems such as unstable placement, irregular rotation, affected welding quality, low welding efficiency, and high rework rate. (3) C...
