Abstract:
A drill slide (1) for a drilling apparatus, said slide (1) adapted to slidably support a drifter (6), said slide (1) comprising a telescopic shaft (2) having a first elongate member (3) telescopically slidable with respect to a second elongate hollow member (4); a first rail mounted to or integral with said second elongate hollow member (4) upon which said drifter (6) travels along; and wherein a second removable rail (7) is adapted to be fitted adjacent to said first elongate member (3) in an extended configuration, where said second rail (7) is end to end with said first rail (5) thereby allowing said drifter (6) to slide along said first (5) and second rails (7).
Abstract:
A telescopic feed beam for a rock drill, comprising a lower beam (1) and an upper beam (2) arranged to move with respect to each other in the longitudinal direction. The cross section of the lower beam (1) is such that there is a groove-like open space (1b) at the bottom of the lower beam and a transfer cylinder (5) between the lower beam (1) and the upper beam (2) is mounted in the groove.
Abstract:
A drilling apparatus for drilling underground, small diameter bore holes wherein a support frame of the apparatus is formed in part by a pair of hydraulic cylinders arranged parallel one to another. A head mounting plate that carries the drill motor is releaseably attached to a barrel portion of each hydraulic cylinder and the barrel portion is urged by fluid pressure along a support rod extending axially through the barrel. The ends of the support rods are attached by front and rear supports to form a frame that is anchored in position relative to the movable barrel.
Abstract:
Die Bohrsäule (1) weist einen teleskopierbaren Zylinder (2) mit einem Außenrohr (6) und einem in dem Außenrohr (6) dicht geführten Innenrohr (32), einen mit dem Innenrohr (32) verbundenen, pneumatisch beaufschlagbaren Druckluftmotor (3), einen mit dem Druckluftmotor (3) koppelbaren Werkzeugadapter (4) und Steuermittel zur gezielten Überführung von Arbeitsmedien mindestens zum Zylinder (2) und zum Druckluftmotor (3) auf. Das örtlich lagefixierbare Außenrohr (6) bildet Träger eines Druckluftanschlusses (44) sowie eines Wasseranschlusses (45), der Steuermittel, von Druckluft zum Zylinder (2) sowie zum Druckluftmotor (3) überführenden flexiblen Druckluftleitungen (12, 55) und einer Wasser zum Werkzeugadapter (4) überführenden Wasserleitung (57). Das Innenrohr (32) ist gegen Verdrehung gesichert mindestens mittelbar in dem Außenrohr (6) geführt.
Abstract:
Vorrichtung zum Bewegen eines Rohres (10,11) mit einem Druckraum (6), der in das Rohr (10) einsetzbar ist, Umsetzungsmitteln (4), durch welche eine Druckänderung in eine Bewegung eines Körpers umgesetzt wird, Verbindungsmitteln (2) zum Übertragen von Bewegung des Körpers in eine Bewegung des Rohrs (10), wobei der Querschnitt des Druckraums den Rohrquerschnitt soweit wie möglich ausnutzt, um eine möglichst große Angriffsfläche für das Druckmedium nutzen zu können.
Abstract:
After an existing lower rod lock (100) is tightened to keep a pump rod (3000), which extends from a stuck pump rotor, from sliding down into a well, an existing upper rod lock/drive (300) is loosened to allow the rod to slide through the upper rod drive. The present invention is then mounted to the rod or an extension thereof, and locked in place by means of a temporary lifting rod lock (4000). When hydraulic fluid is passed through the system of the present invention, a hydraulic cylinder (s) (3600,3700) causes the rod to be pulled upwards, thereby pulling a pump rotor upwards out of sand buildup which entraps said pump rotor.
Abstract:
A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to realisably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment. The pipe running tool having a greater slip back offset such that drill pipe and drill pipe tool joints may be passed through the central passageway of the tool without interfering with the front of the slip.
Abstract:
A load compensator is disclosed for use in connection with a pipe running tool. The load compensator includes an outer housing connected to the portion of the pipe ruru'1ing tool that holds the pipe segment. A piston is disposed within the housing, and is connected to a top dri\re system of the pipe running tool. The housing is fonned with a first port through which pressurized air is delivered inside the housing to drive the piston within the housing. A second port is disposed at a selected location on the housing, such that when the piston is advanced past the second port, pressurized air passes through the port, and causes the control circuit to stop delivering air through the first port. Once pressurized air no longer flows through the second port, the control circuit causes air to be delivered to the first port.
