The invention relates to pipe transport and can be used when performing technological operations in the pipe processing industry.

The purpose of the invention is to increase the reliability of work.

FIG. shows support, general view; figure 2 is a section aa in fig.I; on fig.Z - type B on fig.Z; Fig. 4 is the assembly 1 of Fig. 1 (structural embodiment of a drive for approaching and diluting cylindrical rollers).

The roller support for the pipe contains a pair of cylindrical rollers 1, two arm shoulders supporting them 2, pivotal about axes 3 and connected with their lower shoulders through rods 4 by means of a common finger 5 with rod 6, a vertically mounted piston cylinder 7 ) having an upper annular protrusion 8 and a piston 9 dividing the cylinder cavity into the rod 10 and piston piston. The cylindrical stationary guide 12 has an upper claw 13 rigidly connected to the cylinder rod and installed with A spine of vertical movement 5 and a spring 14 placed inside a guide around the cylinder in cooperation with its upper annular protrusion. The bark of the tapered rollers 15 is located in the uprights 16, which, in turn, are mated with each other fixedly and horizontally and vertically in a vertical direction with a dovetail connection. The screw mechanism for moving the tapered rollers is made in the form of vertical screws 17 and nuts 18 fixed to their stands fixed in the stands 19 and fixedly connected to the base 20. The base is equipped with outriggers 21.

The device works as follows.

The support is placed on the ground and, depending on its profile, the horizontal position of the base 20 is provided by adjusting the outriggers 21. Depending on the diameter of the pipe being processed, the cylindrical rollers 1 are retracted or separated by wringing or extending the rod 6 of the piston cylinder 7. The driving force or the pushing force of the rod at the same time through 13, with which it is connected, and a common horizontal finger 5 provides breeding

or the reduction of t g 4, which, acting on the lower shoulders of the levers 2, cause the upper shoulders, connected to the cylindrical rollers 1, to rotate relative to the axes 3.

After finishing the processing of the pipe associated with its rotation, it is lowered by a piston cylinder onto the tapered rollers 15 T1, by diluting the upper arms of the swing arms 2, then the pipe is fed in the longitudinal direction using tapered rollers. The extension or retraction of the rod is carried out by supplying the working medium to the piston 11 or rod 10 cylinder cavities. The downward movement of the cylinder body is eliminated by the action of the compression spring 14 on it.

The implementation of the pivoting levers with two shoulders and through the glands mounted on a common horizontal finger fixed on a cap movably coupled to the guide base allows the beating of the processed pipe to be transferred to reciprocating displacement of the cap relative to the guide when the tube is rotating, and the interaction of the piston body. the cylinder of the drive for approaching the cylindrical rollers with a spring mounted on the base inside the guide allows to damp this runout, relieving the structure and the image om enhancing its reliability in operation.

Chain moving joints of axles, on which two shoulders are installed, with the base and the taper roller stands in between each other in the horizontal direction provide a fixed stable position of the support.

In addition, the connection of the piston-cylinder rod with the lid and a common horizontal finger fixed on it, on which two lower arm swivel levers are installed through their lower arms, keeps the machined pipe aligned with the technological equipment, since cylindrical rollers connected to the upper arms of the swivel arms by pulling or pushing the piston rod rod to the previously installed pipe, eliminating its displacement in the horizontal plane.
