Abstract

The device comprises a drill bar (14) with a retractable head (16) and central holding shaft (18) aligned with the drill bar and to which a counter pressure plate (32) is fixed. A number of centering devices (22) extend radially outwards from the holding shaft (18). The holding shaft comprises different individual segments (18a,18b), which are connectable to one another by threads (20) or pin connections. The outer diameter of the retractable head (16) is equal to the outer diameter of the pipe (24) to be retracted or larger than it. On one individual segment of the holding shaft centering devices (22) are located in at least two positions axially spaced apart. Each centering device comprises a number of regulatable hydraulic cylinders which extend radially outwards from the holding shaft and can be regulated individually. The centering devices incorporate a number of leaf springs extending radially outwards from the holding shaft and having a curved shape.
