摘要： In a pivotally mounted rock drill boom and feed bar apparatus, the pivots of the boom and the feed bar positioner include angle sensors comprising cam actuated fluid pressure regulating valves. The pressure regulating valves are disposed in a control circuit which includes a pilot pressure fluid actuated control valve which senses an unbalanced pressure signal generated by the sensor connected to the boom pivot in response to movement of the boom about said pivot. The control valve responds to the unbalanced pressure condition by valving fluid to the feed bar positioner actuator to maintain the feed bar in a predetermined directional attitude. The angle sensor mounted on the boom pivot may be adjusted independent of movement of the boom to cause a change in the directional attitude of the feed bar as desired.

摘要： Material is continuously dislodged by a pair of conical cutters and displaced outwardly toward the ribs of the room as the mining machine advances. The dislodged material is picked up by a transversely extending spiral conveyor and conveyed inwardly from the ribs onto the bottom strand of a flexible belt. The flexible belt has one end portion coiled on a lower rotatable spindle at a fixed discharge station adjacent the room entry. The other end portion of the flexible belt is coiled on an upper rotatable spindle positioned above the lower rotatable spindle. The intermediate portion of the flexible belt forms a lower conveying strand portion extending from the lower coil around a cylindrical idler or turn around pulley and an upper strand portion extending from the upper spindle to the turn around pulley. The upper strand portion extends between a pair of driven compression rollers to pull the upper strand toward the mining machine from the upper spindle.

摘要： Earth drilling apparatus of the generally conventional type comprising a wheel supported vehicle having a pivoted derrick or mast which is moveable between a substantially horizontal transport position above the vehicle and a substantially vertical drilling position adjacent the rear end of the vehicle, the mast having a rectilinearly moveable carriage supporting a drilling head. It is characterized by a longitudinal drill pipe storage compartment adjacent one side of the vehicle, a pivoted boom at the top of the mast for transferring a drill pipe from the storage compartment to a temporary vertical holding position, the drilling head being pivotally mounted to its carriage for movement above the upper end of the holding position at which the pipe is connected to the drilling head, the drilling head and its attached pipe then being moveable to drilling position, this procedure continuing until the drilling reaches a desired depth. In the removal of the pipe string, the drilling head is moved to an inoperative clearing position laterally of the drill pipe axis and a traveling hoist block, moveable along such axis, is attached to the uppermost pipe of the string. The string is then elevated one pipe increment, the uppermost pipe disconnected from the string therebelow, and the hoist block lowered. At or near the commencement of lowering, the lower end of the disconnected pipe is manually guided into the rear end of the storage compartment and as the traveling hoist block lowers, it slides forwardly into the storage compartment to its original position therein.

摘要： A method for drilling an oil or gas well or the like which does not utilize a conventional derrick and rig which requires several operators and extensive moving equipment and the like, but rather the drilling is carried out with a minimum of simplified equipment. The invention contemplates mounting a generally up and down travelling rotary table over a well bore site. It includes the step of suspending a drill string from the rotary table and holding the drill string therein against downward movement relative thereto, with the drill string having drill collars and a drill bit on the lower end thereof. The rotary table is simultaneously rotated and lowered to effect drilling of the well bore while flowing a drilling fluid through the drill string. Thereafter, rotation of the rotary table is terminated and the rotary table disengaged from the drill string while supporting the drill string at a point below the rotary table. The drill string is held against rotational and downward movement during this supporting step. An additional section of pipe is placed in the rotary table and held therein against rotational and downward movement relative thereto. The lower end of the additional section of pipe is connected with the drill string by lowering and rotating the rotary table. Thereafter, the drilling operation is resumed by rotating and lowering the rotary table. In certain instances, the drill string may be held against both up and down movement while being supported at the position below the rotary table and likewise may be supported against both up and down movements relative to the rotary table at certain times.

摘要： A boring machine having a cutter head rotatably mounted on a hydrostatic bearing. High pressure water is supplied to passageways between confronting bearing surfaces which react axial and radial loads and which are capable of relative rotational movement. The flow of pressurized water discharges from the passageways to prevent contamination of the bearing by the ingress of material removed by the cutter head in operation.
