Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described:

[0034] Such as Figure 1-2 As shown, the present invention provides a butt welding tool suitable for the group butt welding of the ring longitudinal weld of the outer grid cylinder of the PDH device: the welding tool includes a support ring assembly 1, a shaft support assembly 2, a connecting assembly 3, a main shaft 4 and a main connecting rod 5 . The main shaft 4 of the welding tool is fixedly connected with a plurality of support ring assemblies 1. The plurality of support ring assemblies 1 make the coaxiality and cylindricity of the paired net cylinder more accurate, and the outer circumference of the plurality of support ring assemblies 1 passes through the The main connecting rod 5 is connected, and the two ends of the main shaft 4 of the welding tool are fixed on the shaft support assembly 2 . In this embodiment, there are shaft bracket assemblies 2 at the front a...

Abstract

The invention relates to a circular and longitudinal weld joint assembly welding tool suitable for an PDH device outer net barrel. A plurality of supporting ring assemblies are fixedly connected to amain shaft of the welding tool, the periphery rings of the supporting ring assemblies are sequentially connected through main connecting rods, and the two ends of the main shaft of the welding tool are fixed to shaft support assemblies. The circular and longitudinal weld joint assembly welding tool suitable for the PDH device outer net barrel is reasonable in structure, easy and convenient to use,easy to disassemble, stable, durable and high in precision, and can effectively solve the problems of pairing, rounding and deformation control and the like during welding of the large PHD outer netbarrel.

Description

technical field [0001] The invention mainly relates to a special-purpose welding tool, in particular to a butt-welding tool suitable for the butt welding of the ring longitudinal weld seam of the inner member of the petrochemical reactor of the PDH device, which belongs to the welding tool. Background technique [0002] Large-scale petroleum refining projects are increasing rapidly, and the quality and precision of internal components of large-scale PDH devices are increasingly demanding. In order to make the internal components of the PDH device larger in size, with a diameter of about 6 meters and a length of about 20 meters, it is necessary to carry out tailor welding and welding of the large internal component grid cylinder. At present, most of the welding uses simple tooling for manual welding, and the welding efficiency is low. Quality accuracy is difficult to guarantee. In order to improve the welding quality and efficiency, the existing technology is exploring autom...
