Abstract

The invention relates to the construction and can be used in the construction of pipelines. The aim of the invention is to reduce the discharge line under the pipeline. and an increase in traction force on the adhesion of the self-propelled support of the pipeline due to the placement of the pipeline in the plane of the longitudinal axis of the support and the provision of traction between this support and the pipeline. The self-propelled support contains two tracked carts 2 articulated with a controlled hinge 1, with the upper tracks being connected to the lowering carts 5 with their lower caterpillars, while the pipeline 8 rests on the upper crawler 7. The supporting part of the tracked carts 2 and 5 is made in the form of pneumatic wheels and pneumocameras. Racks 15 are fixed on the pylon 3, on the ends of which adjustable piping supports 16 are installed. The self-supporting support is placed under the piping and when the drive is switched on, the tracked trolley 2 is moved, while the tracked conveyor belt 7 of the trolley 5 rolls along the pneumatic chambers 6.

Description

The invention relates to the construction and can be used when laying pipelines.

The aim of the invention is to reduce the retraction band and increase the traction force on the adhesion of the self-propelled pipeline support by placing the pipeline in the plane of the longitudinal axis of the support and providing traction interaction of this support with the pipeline.

Fig „1 shows the proposed device, side view; FIG. 2 is a section A-A in FIG.

The self-supporting support of the raised pipeline section contains two ground-supported crawler carts 2 connected with a controllable hinge 1 with axles of carrying rollers, a power drive located on frame 3, power cylinders 4 (there are two of them and they are located at an angle at an angle to each other in plan) heading and pipe support system with support rollers. The latter is made in the form of a tracked trolley 5 with pneumatic chambers 6 linearly arranged as the supporting rollers, the width of which is equal to the width of the surrounding tracked belt 7, and the end aktiruet caterpillar upper conduit to the lower surface 8 and the bottom caterpillar supported on the upper caterpillar bogie 2. gruntoopornoy Nesushie rollers of the trolley are made from a linear array of sequentially alternating on the axles 10 and E pnevmokoles pneumatic chambers 11, in contact with the upper and lower tracks.

The stiffness of the pneumowheels and pneumocameras is in the ratio (1.5-3.0): 1, 0. The axes are suspended at the ends of the balancers 12, which on the axes 13 are supported by rigid longitudinal beams 14 of the space frame 3 of the self-propelled support. The spatial frame also includes fixed limiting posts 15, on the tips of which there are adjustable stops 16 for the pipeline. In the middle part, through the rollers 17, it is connected with the type-setting longitudinal beams 18 of the pipe support carriage. Tracked belts and gantry support pipe trucks are made of elastic

material.

I

Self-propelled support set under the pipeline. When the power drive is switched on, the running around the pneumatic wheels 10 and the pneumatic chambers 11 caterpillars of the support trolleys 2 begins. At the same time, these caterpillars are driven into motion with the transmission of the pipes of the support trolleys

5. run-in on pneumocameras

6. At the same time, the pipeline 8 is raised from the ground and insulating or other works are performed on it. In terms of the curves, the pipeline of the self-propelled support fits into the curve due to the presence of the hinge 1 controlled by the power cylinders C,

Thus, due to the location of the support directly under the pipeline, the strip of land under it is reduced.

During operation of the support in areas with a low bearing capacity, skidding is excluded, since the ha from the power plant is realized not only by coupling with the ground of the bearing support carts 2, but also by coupling with the insulation of the pipeline of the support pipes 5.

Thus, due to the presence of a tractive action of the support, not only with the ground, but also with the pipeline, an increase in the force of grip of the support against the clutch is provided.
