Description

LAYER FOR WINDING LENGTH STEEL

DRUM PIPE

The utility model relates to the field of exploitation and underground

repair of oil and gas wells using continuous

steel pipes.

When performing repair work on well restoration

long oil pipes are used for oil and gas production,

wound onto a drum using stackers.

Known stacker winding long steel pipes on

a drum comprising a drum, a drum drive, a lead screw,

stacker carriage, pipe caster rollers, device for

adjusting the height of the stacker relative to the drum

and lead screw drive (AS No. 832038, ЕВВ 19/00, publ.

05/23/81, bull. .NO 19).

In the winding process of a long steel pipe, with rollers

tightly cover it from two sides. Pipe displacement force

across the drum is transmitted by the flanges of the rollers, while the height

stacker adjustable by operator, and long steel pipe

It rolls in either the upper or lower roller.

A disadvantage of the known stacker is that they are created

additional loads on the pipe that cause it to

intense wear.

The technical effect of using the proposed technical

decisions can be expressed in increases in the service life of steel

pipes.

The specified technical result is achieved as follows.

stacker, pipe coverage rollers, adjuster

stacker height relative to drum and drive

lead screw. In this case, the stacker carriage is equipped with two

pairs of rollers, one of which is located horizontally, and

the other is upright. The distance between the rollers of each pair in

The coverage area of the pipe is larger than the outside diameter of the pipe.

In addition, the distance between the rollers of each pair is selected from

ratios: (1.5 - 2) D, where D is the outer diameter of the pipe.

Due to this, the spindle drive is equipped with two pairs

rollers, one of which is located horizontally and the other vertically, and the distance between the rollers in each pair

significantly larger than the outer diameter of the pipe, between the pairs

rollers formed a rectangular space in the form of a window. At

this horizontal pair of rollers serves as limiters

the vertical position of the pipe and practically does not contact

pipe, which eliminates the creation of additional loads on the pipe,

associated with insufficiently precise adjustment of the height of the lift

stacker.

The essence of the technical solution is illustrated by the drawings:

In FIG. 1 shows a general view of a winding stacker

long steel pipes per drum;

In FIG. 2 is a view A of FIG. 1;

In FIG. 3 shows a stacker carriage;

In FIG. 4 - section aa;

In FIG. 5 - section BB.

Stacker for winding long steel pipes on a drum

contains a drum 1, a drum drive 2, a device for adjusting

screw 4, stacker carriage 5, drive screw 6, a horizontal pair of rollers 7 and a vertical pair of rollers 8. The device operates as follows.

During operation, the long pipe 9 is placed in a rectangular window formed by a horizontal pair of rollers 7 and a vertical pair of rollers 8, is sent and fixed on the drum 1 in one of the extreme positions. The drum 1 with the help of the drum 2 is given a rotational movement. Using a device for adjusting the position of the stacker in height relative to the drum 3, the optimal position of the carriage of the stacker 5 relative to the lengthy pipe 9 along the entire length from the pipe feed source to the drum 1 is selected. In this case, the lengthy pipe 9 should be between a horizontal pair of rollers 7, not in contact with them. As the drum 1 is filled with a long pipe 9, the carriage of the stacker 5 along the lead screw 4 moves from the extreme position to the opposite side of the drum 1 by the drive of the screw 6. In this case, the long pipe 9 located between a pair of vertical rollers 8 is in contact with one of the rollers . Thus, the necessary force is provided for moving the pipe along the axis of the drum and the winding of the lengthy pipe 9 on the drum is regulated. When the stacker reaches 5 sides of the drum,

opposite from the beginning of its stroke, the lead screw 4 receives reverse rotation, and the winding of the long pipe 9 occurs in the opposite direction.

Claims (2)

1. Stacker for winding long steel pipes onto a drum containing a drum, a drum drive, a spindle, a stacker carriage, pipe grasping rollers, a device for adjusting the stacker height in relation to the drum and a lead screw, characterized in that the stacker carriage is equipped with two pairs rollers, one of which is located horizontally and the other vertically, and the distance between the rollers of each pair in the pipe coverage is greater than the outer diameter of the pipe. 2.
