PURPOSE:To easily move a high-temperature composite tube vertically by incorporating a sliding cylinder in the gear case of a general purpose reciprocal piston driller in vertically moving the composite tube to be used when connecting or disconnecting the joint of the composite tube. CONSTITUTION:A driller 2 is of a general purpose mechanism constituting the main portion of a general purpose reciprocal piston oil-feed system driller 1 and capable of drilling slant hole by turning and inclining the axial center. Angles 4 for fixing and supporting main pillars 3 with vertical and spiral elevating guides are also provided. A composite tube 15 is lifted up by a fallen discharge hose 10 and a swivel 12 on the ground's surface and then vertically errected to the left side of the driller 1 by generating oil pressure. |
