Tie-drilling apparatus

摘要

The tie-drilling apparatus (AB) has a hydraulically loadable drilling machine (2) which is carried by a supporting device (1). The supporting device (1) has a telescopic cylinder (4) and at the same time ensures the advance during drilling. The control and guidance of the drilling apparatus (AB) take place via a guide arm (8) which is articulated on the piston rod (27) of the telescopic cylinder (4) and on the free end of which is arranged a transverse link (10) which carries the actuating levers (15, 16) necessary for controlling the drilling apparatus (AB), so that simultaneous guidance and control of the drilling machine (2) are possible. The hydraulic supply to the tie-drilling apparatus (AB) takes place via a common delivery line B and a return line T. <IMAGE>
