摘要： An apparatus, method, and system for determining the propagation delay for a downhole wire and/or for monitoring the integrity of a downhole wire. The apparatus includes a first tool component and a second tool component spaced apart from the first tool component and communicatively coupled by a wire. The tool components include impedance altering devices configured to alter, for a predetermined period of time, either the source impedance at a first termination point of the wire and/or the load impedance at a second termination point of the wire sufficient to generate a characteristic signal reflection upon the transmission of a signal along a length of the wire between the first tool component and the second tool component.

摘要： The invention provides a bit breaker comprising a plate that bounds a pipe slot. The bit breaker has two jaws that are at least generally parallel and that respectively define two working surfaces located on opposite sides of the pipe slot. The jaws are each mounted removably to the plate. In some embodiments, the invention is an assembly that further includes a pipe, tool section, tool or pipe joint received in the pipe slot. The pipe, tool section, tool or pipe joint has formed therein two crosswise grooves located on opposite sides of the pipe, tool section, tool or pipe joint. In some embodiments, the plate defines two fixed arms and a fixed base leg, with the two jaws mounted respectively against the two fixed arms. The bit breaker can have an adjustable arm such that the pipe slot can be surrounded about 360 degrees by the bit breaker.

摘要： A method for assembling a down-the-hole drilling apparatus including a drilling device including a casing and a drilling unit arranged during drilling in connection with the casing. The drilling unit includes a drilling head including a drilling arrangement including a first drilling member for drilling a center hole and a second drilling member for reaming the center hole. The drilling members are mutually power transmittingly coupled during drilling to cooperate for rotational, feeding and/or hammering, and removably coupled to enable removal of the first drilling member from a hole. The casing is arranged to be pulled into the hole through a shoulder arranged at an end of the casing. At an opposite end of the drilling arrangement with respect to a drilling surface, is arranged a skirt including a radial internal shoulder for pulling the casing into the hole by cooperation of the internal shoulder and an external shoulder at the end of the casing.

摘要： The invention relates to a method pertaining to a drill support device (290) comprising two relatively movable drill support arms (241; 242), wherein a support space is formed between opposite arm sections (261, 262), in which a drill steel (201) is adapted to be guided and wherein said space is opened and closed by relative displacement of said sections (261, 262). The method includes the step of: —fixing (S401) at least one of said drill support arms (241; 242) by sealingly clamping between, on one side, a support element (670) and, on the other side, a housing section (650), which accommodates a hydraulic cylinder (605) with a hydraulic piston (680), on which hydraulic cylinder (605), said drill support arm (241; 242) is revolvingly mounted, wherein said drill support arm (241; 242) is clamped by means of a screw means (640) by which the housing section (650) is displaceable. The invention also relates to a computer program product comprising program code (P) for a computer (200; 210) for implementing a method according to the invention. The invention also relates to a drill support device (290) and a vehicle (100) equipped with the drill support device (290).

摘要： A device for the movement and mutual assembly of segments of an excavation battery, like for example auger or rod segments, for the composition of an excavation battery and for connecting the battery to a digging machine is disclosed. The device has: an upper joint integrally and removably connectable to a driving tube or to a rotary head of the digging machine; a lower joint integrally and removably connectable to a segment of the excavation battery; a flexible element that connects the two joints being constrained with one own end to the upper joint and connected with the other own end to the lower joint, so that the lower joint can slide along the flexible element moving with respect to the upper joint between a disengaged extended position, and an engaged contracted position; and a stop element that limits the sliding of the lower joint away from the upper joint along the flexible element.
