AUTONOMOUS INTRATUBAL TRANSPORT DEVICE Russian patent published in 2014 - IPC F16L55/34 B62D57/28 B62D57/32 

FIELD: machine building.

SUBSTANCE: device comprises two terminal modules of identical design. Each module comprises a vertical panel with at least three transverse electric actuators hingedly fixed on it and arranged evenly, and on their bodies there are freely rotating support wheels with the possibility of their movement along the inner surface of the pipeline. Between the terminal modules there is a middle module, comprising two end panels, between which a longitudinal electric actuator is rigidly fixed, as well as at least two telescopic guides. The middle module is connected to each terminal module by means of a spring-loaded universal joint, one axis of which is fixed on the end panel of the middle module, and the other axis - on the vertical panel of the appropriate terminal module. The spring covering the universal joint with its one end rests against the end panel of the middle module, and with the other end - to the thrust orifice, installed on the axis of the universal joint, connected with the vertical panel of the appropriate terminal module.

EFFECT: invention makes it possible to improve operational properties of an intratubal transport device due to flexibility and lightness of design, reduced friction during its motion in a pipeline.
