FIELD: pipeline transportation; construction of the pipelines. ^ SUBSTANCE: the invention is pertaining to construction of the pipeline transportation and may be used in the structure of the pipe welding stations and the pipe welding complexes at the assembling and welding of the slewing joints of the pipes within the range of their diameters from 325 mm up to 1420 mm. On the frame there are the adjustable in height front and rear supports, on which there is the boom with the centering skid connected to the hydraulic aggregate and the hydraulic control equipment. The rear part of the boom is supplied with the support based on the bearings and with the hydraulic hinge, that ensures the rotation movement of the boom with the centering skid and allows to bring out the hydraulic aggregate with the hydraulic control equipment from the centering skid in the convenient place for servicing. The coupling of the hydraulic aggregate with the centering skid and the hydraulic control equipment is exercised by means of the pipelines through the hydraulic hinge. The front part of the centering skid contains the shell, using which the boom rests on the bracing jack and so simplifies the design of the bracing jack and realignment for welding of the pipes of the different diameters. The invention allows to make wider the technological capabilities of the production line for assemblage and welding of the pipes butts, to increase its operational reliability. ^ EFFECT: the invention allows to make wider the technological capabilities of the production line for assemblage and welding of the pipes butts, to increase its operational reliability. ^ 3 cl, 2 dwg |
