Description

one

The invention relates to a cadmium transport vehicle for movement within a pipeline and can be used to clean a pipeline, diagnose it, and transport various small loads.

A well-known pipeline traction carriage, comprising a housing, on which, parallel to its longitudinal axis, is installed passages 1e of rollers connected by means of mechanical transmission with a rotational drive.

However, this carriage has insufficient traction, which limits its technological capabilities when performing various works in pipeline II.

The closest to the invention in terms of technical significance and the achieved result is a self-propelled trolley for moving inside the pipeline, containing a cylindrical housing, on the outer surface of which spring-loaded rollers are mounted inclined to its longitudinal axis to interact with the inner surface of the pipeline, remote control elements and power source.

A disadvantage of the known carriage is a large frontal resistance, which leads to a large expenditure of energy both on the movement of the carriage and on pumping fluid 12).

The purpose of the invention is to reduce the energy consumption for the movement of the trolley.

The goal is achieved by the fact that in a self-propelled carriage for movement inside a pipeline containing a cylindrical body, on the outer surface of which spring-loaded rollers are mounted inclined to its longitudinal axis for interacting with the inner surface of the pipeline, from

Figure 1 shows a self-propelled carriage in the pipeline, a longitudinal section in figure 2 - section A-A in fig. D.

A self-propelled car consists of a body 1, made in the form of a pipe segment, the open ends of which have the form of truncated cones 2 and 3, the large bases of which are located near the inner surface of pipe 4. On the outer surface of the body in an annular cavity 5, covered from the incident flow of liquid and 3, on the spring-loaded brackets 6, the running rollers 7 are installed, the rotation axes of which are arranged at a certain angle, v to the longitudinal axis of the pipeline 4. The rollers 7 are connected through the couplings 8 to the rotational drives 9, which can t be made in the form of well-known gear motors. In the annular cavity 5 there is also a power source, for example, a battery 10, remote control elements and various analyzers (not shown).

For the movement of the trolley, remote control bodies (not shown) include actuators 9, which rotate the rollers 7. As a result, the trolley body 1, rotating, moves along the axis of the pipeline A. Fluid that is or is pumped through pipeline 4, passes freely through the central opening of the body 1 of the trolley.

The application of the invention allows to reduce the drag of the carriage up to 10 times and, consequently, significantly reduce the energy consumption and the range of the stroke. The energy consumption for pumping fluid inside the pipeline is also significantly reduced.
