Abstract

FIELD: construction of pipeline transport.

SUBSTANCE: invention can be used at construction and reconstruction of overground pipelines, particularly, processing pipelines of compressor stations. Longitudinal slots are made in pipeline support from opposite sides, and brackets are secured. Post supporting the pipeline is arranged for longitudinal reciprocation in space of base. Support is furnished with supporting-and-swiveling units installed in upper part of support post and in lower part of base, and with levers whose axle is secured in bracket. One end of lever is made to thrust against end face of post, and weight is secured on other end of lever to travel along lever for creating regulated force acting onto pipeline.

Description

The invention relates to the construction of pipelines and is used in the construction and reconstruction of elevated pipelines, in particular technological pipelines of compressor stations.

A well-known support for the pipeline, in which the load and displacement compensator contains two bogies with brackets and travers pivotally mounted on them, interacting with the support pad (Application for invention 2001117186/06, IPC F16L 3/01. Publish. March 20, 2003. Bull. No. 8 (part 1)).

The disadvantages of the device include its structural complexity and, as a result, low reliability.

Closest to the claimed one is a pipeline support containing a hollow base fixed in the ground, in which longitudinal grooves are made from opposite sides, a stand designed to support the pipeline, placed in the base cavity with the possibility of longitudinal reciprocating movement and equipped with brackets supporting the movable blocks, placed in the grooves of the base, on which the supporting fixed blocks are fixed over the longitudinal grooves, the brackets, the loads are connected to the cables, each of which therefore, it bends around the respective fixed and movable blocks, while the ends of the cables are fixed on the base above the longitudinal grooves (RF Patent No. 2211981, IPC F16L 3/26. Publish. 09/10/2003).

The disadvantages of the prototype is the following:

- the inability to smoothly control the reaction force of the support acting on the pipeline;

- limited applicability of the support to maintain the pipeline with a large mass of linear meter of pipe and the presence of massive additional equipment (taps, plugs, etc.), for example, technological pipelines of compressor stations. When using a device with two pairs of blocks, a significant mass of cargo is required to provide an adequate support reaction, numerically equal to 1/2 of the mass of the supported section of the pipeline. In the case of an increase in the number of blocks, the required mass of the load decreases, however, the amount of space required to move the load increases, the complexity and material consumption of the device increases;

- low reliability of the support, especially when working in conditions of low air temperatures, the presence of snow, ice, etc.

The objective of the invention is to create a support that does not require significant work space, reducing the complexity and material consumption of the support, increasing the reliability of its operation.

The technical result achieved by the implementation of the invention is to provide smooth control of the force acting on the pipeline during its operation or seasonal movement of soils.

This is ensured by the fact that the support of the pipeline, containing a hollow base intended for fixing in the ground, in which longitudinal grooves are made on opposite sides and the brackets are fixed, a stand designed to support the pipeline, placed in the base cavity with the possibility of longitudinal reciprocating movement, according to the invention equipped with slewing assemblies installed in the upper part of the support strut and in the lower part of the base, and levers, the axis of which is mounted on the bracket, when this one end of the lever is made with the possibility of abutment in the end face of the rack, and at the second end of the lever is secured with the ability to move along the lever load to create an adjustable force acting on the pipeline.

The invention is illustrated by the drawing, which shows the support of the pipeline in a section perpendicular to the longitudinal axis of the pipeline.

The pipeline support consists of a hollow base 1 located in the ground. In the cavity of the base 1, a rack 2 is arranged with a possibility of vertical reciprocating motion. A stop-rotary assembly 3 is installed in the upper part of the strut 2 and the lower part of the base 1. On the support-rotary assembly 3 is supported pipeline 4. In the side walls of the base 1, the grooves 5 are diametrically opposed and the brackets are fixed 6. The brackets 6 of the levers 8 are fixed to the brackets 6. One end of the lever 8 is made with the possibility of abutment against the end of the rack 2, and at the second end ychaga 8 weight 9 is fixed.

With the vertical movement of the pipeline 4 or soil 10 together with the base 1, the relative movement of the rack 2 and the rotation of the lever 8 relative to the axis 7, mounted on the bracket 6.

The support is made in such a way that when creating the required force on the pipe 4, the lever 8 is perpendicular to the vertical axis of the support.

The installation of the support is as follows.

Weights 9 are installed on the levers 8 as close to the center of the support as possible, which ensures the minimum force acting on the pipeline 4. The central part of the support, limited by stop-turning devices, is turned, orienting the levers 8 parallel to the axis of the pipeline 4, thereby minimizing the working space needed for the support. By moving the load 9 along the lever 8, the force acting on the pipeline 4 is smoothly regulated until the desired value is reached.

The claimed invention in comparison with the prototype allows to simplify the design and adjustment of the efforts of the support, reduce the working space for its installation, to increase the reliability.
