摘要： A portable rock drill rig includes a pair of telescoping struts for supporting and positioning a mast or feed beam. The struts are connected at their upper ends to a support bracket which is connected to an elongated mast support member by a hydraulic cylinder to provide relative sliding movement between the bracket and support member. The drill rig includes a crawler undercarriage having spaced apart and pivotally mounted crawler assemblies. The lower ends of the struts are each connected to an arm which is fixed to the main frame of the undercarriage. The arms are also connected to respective track oscillation cylinders. The mounting arrangement of the struts provides for improved positioning of the mast for drilling, tramming and transport operations.

摘要： A torque tool having a rotation transmitting, torque sensing, energy absorbing, non-overriding mechanism interconnecting a motor and a rotatable driven head. The mechanism includes a driven member coupled to the head and a driver coupled to the motor with the driver yieldably biased toward the driven member. The driven member has cam surfaces facing the driver engaged by bearing surfaces on the driver. The cam surfaces on the driven member permit rotation of the driver relative to the driven member and are sloped such that a preselected torque between the driven member and driver results in the rotation and translation of the driver relative to the driven member. The translation is communicated for the release of a valve rod which actuates a valve to shutoff the motor. The kinetic energy causing relative rotation after shutoff of the motor is stored and dissipated by springs.

摘要： A drill pipe bushing for stabilizing a drill pipe at the mouth of the well during drilling which includes a frame surrounding the drill pipe axis and a plurality of support arms supported from the frame in a circular array about the drill pipe. The support arms are pivotable about an axis substantially parallel to the axis of the drill pipe. Rollers are attached to each support arm with the axis of the rollers normally parallel to the axis of the drill pipe. A rotatable member encircles the drill pipe axis and a plurality of toggle arms are secured between the rotatable member and the end of a corresponding support arm remote from the connection of the support arm to the frame. Structure is provided for rotating the rotatable member relative to the frame thereby moving the toggle arms and the support arms to move the rollers into engagement with or away from the drill pipe. The rotational axis of the rollers become canted upon both rotation and translation of the drill pipe.

摘要： A speed shifting mechanism for a pneumatic wrench or nutsetter comprises a planetary gear arrangement in the drive mechanism of the wrench in which the planet gear carrier is connected to the driver clutch member of a torque responsive clutch and the planetary ring gear is mounted in a one way clutch to provide for unidirectional rotation of the ring gear. The torque responsive clutch is of the sloping tooth type and the driving clutch member is connected to a piston having opposing faces and fitted in the tool housing to form opposed fluid chambers. Pressure fluid is admitted to one of the chambers at a controlled pressure to act on the piston for holding the clutch in the engaged condition. Movement of the driving clutch member at torque causes pressure fluid at the controlled pressure to be vented and the opposite chamber to become pressurized thereby acting on the clutch to disengage and enable the planetary gear arrangement to become operative to reduce the output speed of the wrench.

摘要： A tensioning mechanism for the fluid conductor hoses of a feed mounted rock drill comprises a plurality of fluid cylinders mounted stationary on a bracket supported midway along the length of the drill feed channel. Elongated tubular pistons are slidably supported in the cylinders and are connected to the respective hoses. The cylinders may be charged with pressure fluid such as grease or the like to bias the pistons to tension the hoses and prevent damage to the hoses or interference with movement of the drill.

摘要： A wrapping bit for insulated conductor wire includes a transverse end face having a shelf projecting from the surface of the end face adjacent the longitudinal wire receiving groove. An insulation slitting knife edge is formed on the shelf and extends along the surface of the shelf in a direction transverse to the longitudinal axis of the wrapping bit. A conductor guide channel intersects the wire receiving groove for guiding the insulated conductor onto the shelf and over the knife edge for slitting the conductor insulation longitudinally and just prior to wrapping the wire onto a terminal.

摘要： The mast of a portable earth drilling rig is mounted for pivotal movement between a horizontal transport position and selected drilling positions. A series of radially spaced apart lateral projections on each side of the lower end of the mast are provided with apertures for engaging laterally extending projections disposed on a pair of telescopic braces mounted on the rig frame. The braces may be selectively positioned for automatic engagement with a predetermined pair of projections on the mast whereby the mast, for drilling, may be positioned in the desired angular attitude.
