TELESCOPIC MAST FOR DRILLING AND ASSOCIATED DRILLING RIG

摘要

A telescopic mast includes at least one first structure including a fixing portion adapted to be fixed to a drill floor. At least one second structure is mobile relative to the first structure, to obtain a telescopic mast. A moving system is adapted to extend and retract a longitudinal extension of the telescopic mast, by moving the second structure. The moving system includes at least one first actuator device, adapted to be fixed to the first structure or to the drill floor at its first end. The second structure is fixed at a first end of at least one second actuator device. At least one supply chamber is adapted to supply at least the first actuator device and at least the second actuator. At least one first actuator device and the at least one second actuator device are aligned along a single direction and operate with opposite directions.

1. A mast for telescopic drilling comprising:
at least one first structure comprising a fixing portion, adapted for being fixed to a drill floor; at least one second structure, the at least one second structure being movable relative to the first structure to obtain a telescopic mast; a moving system, capable of extending and retracting a longitudinal extension of said telescopic mast by moving said at least one second structure; said moving system comprising:
at least one first actuator device, which, at its first end, is adapted to be fixed to said first structure or to said drill floor;at least one second actuator device, to which, at its first end, is fixed said second structure;at least one supply chamber, for supplying at least said first actuator device and at least said second actuator; wherein said at least one first actuator device and said at least one second actuator device are: aligned along a single direction, and operable with opposite directions.
