Abstract
Apparatus for servicing a structure comprises a frame for assembly around the structure, the frame having least one pair of first and second arms pivotally attached at proximal ends thereof to the frame and carrying respective rotating members arranged to contact the structure and driveable to move the frame along the structure.
Claims18
An apparatus for servicing a structure, comprising:
- a frame for assembly or arrangement around the structure, the frame including upper and lower supports provided at axial ends of the frame and a middle support provided between said opposite ends of the frame, said upper, middle and lower supports connected together by a plurality of vertically extending struts to form a generally cylindrical frame;
- a plurality of pairs of first and second arms pivotally attached at proximal ends thereof to the middle support;
- and
- a plurality of pairs of first and second rotating members, attached to distal ends of the respective first and second arms, for contact with the structure;
- the first and second arms extending in axially opposite directions and being pivotable so as to move the corresponding first and second rotating members towards or away from the structure;
- wherein at least one of the first and second arms is arranged to move and pass between a pair of adjacent ones of the plurality of vertically extending struts such that the corresponding first or second rotating member is able to contact the structure;
- wherein the first and/or second arms are drivable so as to pivot towards and away from the structure and bring the respective rotating member respectively into and out of contact with the structure;
- wherein each of the rotating members that contact the structure is arranged on a respective one of said plurality of pivotable arms;
- and
- wherein the upper support extends beyond the first arm such that the corresponding first rotating member contacts the structure at a position between the upper support and middle support;
- and
- wherein the plurality of said pairs of first and second arms and first and second rotating members are circumferentially spaced around the middle support.

- the first and second arms extending in axially opposite directions and being pivotable so as simultaneously to move the corresponding first and second rotating members towards or away from the structure;
- and
- a carriage arranged for circumferential movement wherein the carriage is mounted at or near the second support and is not mounted at or near the first support, the carriage carrying, or being arranged to carry, one or more tools for servicing the structure,
- wherein each of the rotating members that contact the structure is arranged on a respective one of said plurality of pivotable arms, and
- wherein the first arm from the at least one pair of first and second arms extends from the first support in an axial direction away from the second support, and the second arm from the at least one pair of first and second arms extends from the first support in an axial direction towards the second support.
