Drill pipe guiding apparatus for a horizontal boring machine method

摘要

Drill pipe guide apparatus provided for use in conjunction with a pipeline drilling rig as used in drilling substantially horizontal holes for pipe to pass beneath natural or man-made obstruction has a "Vee" shaped trough extending longitudinally from an inclined ramp that serves as a base for the drilling rig. Inverted "Vee", pipe confining members are hingedly mounted at each end of the trough member so as to confine the pipe within the trough but also allow passing a drill string member of larger diameter, such as a stabilizer, by opening and closing each hinge confining member in turn as the stabilizer passes. A hydraulic cylinder member is connected between trough member and the inclined ramp to provide the trough with vertical movement capability for pipe guiding purposes.
