Title: Self propelled apparatus
Inventor: GRAHAM GORDON ALAN
IPC: E21B23/01
Filed: 1991-02-26
Abstract: A self-propelled apparatus (2, 300) is designed to propel itself with sufficient traction so as to act as a tractor to tow. push or otherwise transport equipment along a tube, pipe or well. A main area of application for the apparatus (2, 300) is in the mining and petroleum industries. The apparatus (2, 300) comprises three main sections, an anchor (4) a propelling section or locomotive (6, 304, 305) and a retracting section (8) for retracting the anchor (4) from engagement with an inside surface of a tube, pipe or well. One form of the apparatus (2) (Fig 1) travels in a caterpillar like way. In other forms of the apparatus (300) the anchor and propelling sections (304, 305) are integrated as one unit whereby the apparatus (300) can move in a continuous manner. In these forms, driven wheels (304, 305) are biased into contact with the inside surface of a tube, pipe or well in a manner so that if a force is applied in a direction opposite the direction of travel, the bias increases thus anchoring the apparatus (300) against movement in that opposite direction. To retrieve the apparatus (300) the retracting section retracts the wheels (304, 305) into a casing of the apparatus (300). If power is cutoff from the apparatus (2, 300) the anchor (4) or wheels (304, 305) automatically retract in the apparatus casing. The apparatus (2, 300) is also provided with a fail safe mechanism which allows the application of externally applied mechanical force to retract the anchor in the case where the apparatus (2, 300) otherwise appears to be stuck in the tube, pipe or well. <IMAGE>
