TRANSPORT FACILITY "WORM" FOR MOTION IN VARIOUS SOILS Russian patent published in 2005 - IPC

FIELD: mechanical engineering; performing operations in various soils: chernozem (black soil), sand, plowed fields, river bottom and in pipes.

SUBSTANCE: proposed transport facility has bodies equipped with units for fixation of them relative to surface of motion; they are interconnected by means of motion means. Located on either side from central member are similar groups of members turned through 180° relative to one another. Fixation units are made in form of at least two members-retainers which may be increased in planes perpendicular to axis of transport facility when pressure gas is delivered to member-retainer unit from thermo-sorption gas apparatus. Motion means consist of at least two members-bellows filled with pressure gas; each of them is connected with member-retainer on one side and with end portion of transport facility on other side; end portion is taper in shape; it is forced into soil by member-bellows; it also includes two elastic members with tension-compression springs for motion of transport facility in required direction and return to initial state.

EFFECT: increased operational capabilities.
