    摘要: A drill rod is disclosed. The drill rod includes a casing assembly defining a length that extends axially between a first end and an opposite second end of the drill rod, and a drive shaft rotatably mounted within the casing assembly. The drive shaft extends axially along the drill rod generally from the first end of the casing assembly to the second end of the casing assembly. The drill rod also includes latching pins at the first end of the drill rod and latching pin receivers at the second end of the drill rod. The drill rod further includes latches provided adjacent the latching pin receivers. The latches are movable between latching and non-latching positions. The latches move along an orientation of movement then the latches between the latching and non-latching positions. The drill rod may also include biasing structures that apply retention forces to the latches for retaining the latches in the non-latching position. The retention forces have at least components that extend in directions perpendicular to the orientation of movement of the latches. The drill rod may further include cam arms for moving the latches into a latching position and for retaining the latches in a latching position.

    摘要: A tunneling apparatus is disclosed. The tunneling apparatus includes a drill string formed by a plurality of drill string sections. The drill string has a proximal end and a distal end. The tunneling apparatus also includes a drill head mounted at the distal end of the drill string, the drill head including a cutting unit, a rotational driver that provides torque for rotating the cutting unit, and a thrust driver for applying thrust to the drill string. The tunneling apparatus further includes a vacuum system for withdrawing spoils generated by the cutting unit during operation of the tunneling apparatus and a drilling fluid system for providing drilling fluid to adjacent the cutting unit during operation of the tunneling apparatus. The tunneling apparatus includes a control system that allows an operator to select between a drilling mode and a break-out mode. The tunneling apparatus also includes a control interface that allows an operator to monitor vacuum pressure which concurrently controlling operation of various systems of the tunneling apparatus.

    摘要: The present disclosure relates to a tunneling apparatus including a drill head having a main body and a drive stem rotatably mounted within the main body. The main body defines a vacuum passage offset from the drive stem that extends through the main body from a proximal end to a distal end of the main body. The tunneling apparatus also includes an axial bearing structure for transferring axial load between the drive stem and the main body of the drill head. The axial bearing structure is proximally offset from the distal end of the main body of the drill head. The tunneling apparatus further includes a first radial bearing structure for transferring radial load between the drive stem and the main body of the drill head. The first radial bearing structure is positioned between the axial bearing structure and the distal end of the main body of the drill head and is distally offset from the axial bearing structure.
