Description

The invention relates to the construction of pipeline transport and can be used in the construction of trunk pipelines for various purposes, laid in areas with moving and undulating soils and in earthquake-prone zones.

Known pipe support, USSR author's certificate No. 1024643, F16L 3/20, containing a housing and a spring-loaded lodgement, which ensures the constancy of the total reaction of the springs during upset support.

A disadvantage of the known support is the design complexity, as well as the lack of means for regulating the force and stiffness of the springs, which are reduced as a result of corrosion wear and creep of their material, which over time will lead to a decrease in the bearing capacity of the support.

The closest in technical essence to the present invention is the pipeline support, RF patent No. 2270953, F16L 3/20 dated 06/28/2006, containing a support module consisting of a housing in which a pivotally mounted rocker arm provided with rollers interacting with spring-loaded levers pivotally mounted in the housing, and the axis of the hinge levers do not coincide with the axis of the hinges of the rocker arm and are shifted towards the axis of the tool tray, made in the form of a profile roller, mounted in the beam with the possibility of rotation.

A disadvantage of the known pipeline support is that it does not provide protection for the mechanism located in its housing from atmospheric precipitation and other foreign objects entering the cavity of the housing that could interfere with its performance. In addition, when creating a support for large bearing capacity, its dimensions significantly increase due to the fact that in order to provide the necessary compensating load on the levers using tensile springs of design stiffness, the dimensions of the structure significantly increase due to the need to ensure deformation of the springs to the calculated value, which cases may be unacceptable for the actual design of the pipeline support. Along with the foregoing, the known support does not provide compensation for the horizontal movement of the soil in the direction perpendicular to the longitudinal axis of the pipeline during earthquakes, and to obtain information about the vertical movement of soil under the known support, there is a need for visual monitoring or manual measurements of the movement of the lodgement of the rocker arm relative to the body of the support module, that in conditions of a significant length of trunk pipelines for a number of objective reasons (weather conditions, failure vehicles, the human factor, etc.) makes it difficult to obtain timely information about the movement of soil under one or another support of the pipeline for timely warning of an emergency.

The technical task of the invention is the elimination of the above disadvantages. The problem is solved due to the fact that the support of the pipeline containing the support module, consisting of a housing in which a lodgement is made, made in the form of a profile roller, articulated rocker and spring-loaded levers, and the axis of the lever hinges do not coincide with the axis of the rocker hinges and are displaced in side of the lodgement axis, while the rocker arm is equipped with rollers interacting with spring levers, and the lodgement is rotatably fixed in the rocker arm, has two support modules located in pairs on both the sides of the pipeline, the housing is additionally equipped with cylindrical cartridges with pre-compressed springs placed in them, a beam located on lodgements and equipped with profile rollers that interact with the pipeline, and linear sensors for moving the housing relative to the beam, while the module housing is mounted on the column with the possibility of vertical movement.

Moreover, in each of the cylindrical cassettes two compression springs are arranged concentrically with respect to each other, and the internal spring is equipped with a screw-nut force regulator.

In addition, on the side of the gaps in the walls of the housings of the supporting modules and the side surface of the beam, sealing devices, for example corrugated sleeves, are installed.

In Fig.1, the support of the pipeline is presented in two extreme positions of the rocker arm; figure 2 - pipe support immediately after installation; figure 3 - pipeline support after subsidence of soil under the left column; figure 4 - pipe support after moving the support module of the left column to compensate for possible subsidence of soil under the left column.

The main elements of the pipeline support are:

1 - reference module;

2 - case;

3, 11 - hinges;

4 - rocker;

5 - lodgement;

6 - beam;

7 - profile roller;

8 - pipeline;

9, 16 - rollers;

10 - lever;

12 - an external spring;

13 - an internal spring;

14 - plate;

15 - stock;

17 - skating rink;

18 - cylindrical cassette;

19 - a directing branch pipe;

20 - threaded sleeve;

21 - a pin;

22 - an adjusting screw;

23 - linear displacement sensor;

24 - sealing device;

25 - column;

26 - half clamp.

The pipeline support contains two support modules 1. In the housing 2 of the support module 1, a beam 4 is fixed on the hinge 3, in which a beam 6 of the rocker arm 4 is mounted, for rotation. A beam 6 is placed on the beam 5, equipped with profile rollers 7 on which the pipeline is laid 8. On the beam 4, rollers 9 are fixed, which interact with the levers 10 mounted in the housing 2 on the hinges 11. The axes of the hinges 11 are displaced relative to the axes of the hinges 3 in the direction of the axes of the cradle 5. The levers 10 are spring-loaded with external springs 12 and internal springs 13 es Tarel 14, the rod 15 and the roller 16. The rod 15 is supported by the roller 17. The outer spring 12 and inner spring 13, previously compressed to a predetermined force, placed in a cylindrical cartridge 18 concentrically relative to each other. The cylindrical cassette 18 is fixed on the housing 2. On the plate 14 is fixed a guide pipe 19 of the inner spring 13. In the guide pipe 19 grooves are made. In the cavity of the guide pipe 19 is inserted, from the grooves and with the possibility of axial movement, a threaded sleeve 20 with collars. The threaded sleeve 20 is equipped with a pin 21 that fits into the grooves of the guide pipe 19. The rear ends of the internal springs 13 are supported by the shoulders of the threaded sleeve 20. The threaded sleeve 20 is provided with an adjustment screw 22, which ensures its axial movement relative to the support pipe 19. Linear displacement sensors are installed in the housing 2 23 of the housing 2 of the support module 1 relative to the beam 6, and on the side of the gaps in the wall of the housing 2 and the side surface of the beam 6, a sealing device 24 is installed, for example, in the form of a corrugated sleeve. The housing 2 is mounted on the column 25 using the half clamps 26.

The support pipe works as follows.

After securing the support made for a given load on the columns 25 using half clamps 26 and laying the pipe 8 on the profile rollers 7, the supporting modules 1 are finally adjusted to the actual load by changing the force of the internal spring 13 by rotating the adjustment screws 22 in one direction or another. The load from the weight of the pipeline 8, acting on the lodgements 5 of the rocker arm 4 through the beam 6, is balanced by the total force of the external springs 12 and internal springs 13, transmitted by the levers 10 to the rollers 9 of the rocker arm 4 through the plates 14, rods 15 and rollers 16. When the columns 25 are loaded, the load on the lodgements 5 decreases, and the force balance of the system is violated. In this case, under the influence of the force of the springs, the levers 10 rotate relative to the hinges 11, turning the beam 4 relative to the hinges 3.

As a result of the joint rotation of the levers 10 and the rocker 4, the point of application of force on the rollers 9 from the side of the levers 10 is shifted towards the hinges 11, changing the ratio of the shoulders of the forces of the springs 12, 13 and the supporting reactions of the rollers 9, restoring the force balance of the system, despite the decrease in the total force of the springs 12 and 13 due to their stretching.

When swelling soil under the support, the process occurs in the reverse order. Compensation for horizontal movement of the soil is provided by lodges 5 and rollers 7. The vertical movement of the soil under the columns 25 and its horizontal movement in the direction perpendicular to the axis of the pipe 8 are recorded by linear displacement sensors 23, the signals from which are transmitted to the control room (not shown).

To prevent atmospheric precipitation and foreign objects from entering the cavity of the housings 2 of the support modules 1, sealing devices 24 are installed in the gap between the openings in the housings 2 and the side surface of the beam 6, for example, in the form of corrugated sleeves.

Compensation for the reduction of the force of the springs 12, 13 due to the creep of their material is provided by periodic preloading of the internal springs 13 using the adjusting screws 22.

The proposed solution to the technical problem will improve the safety of operation of the main pipelines laid in permafrost zones and in earthquake-prone zones.
