FIELD: transport machine building.
SUBSTANCE: invention relates to self-propelled vehicles and can be used to arrange movements on inner surfaces, for example, inside tubes with different cross-section shapes, in space between flat surfaces of constant and variable profile, as well as on horizontal and inclined surfaces and can be used both for in-line diagnostics, and for in-pipe transportation of various objects, as well as in repair and construction and rescue operations. Intra-pipe vehicle is made in the form of linear drive, movable parts of which are equipped with symmetrical groups of elastic elements, installed with inclination in opposite directions to axis of linear drive with possibility of alternate elastic action on inner surface of pipe by unidirectional groups of elastic elements of moved parts. Movable parts are equipped with a device for successive pressing of the unidirectional groups of elastic elements to the axis of the linear drive providing direct and reversible movement of the in-tube facility.
EFFECT: invention provides for simplification of design, reduction of overall dimensions and power consumption, and improvement of design reliability.
