摘要:
A pipe handling device with an auxiliary pipe loading device for use with a horizontal boring machine is disclosed. The auxiliary pipe loading device includes an auxiliary pipe receiving member that is connected to a pipe handling assembly at a location remote from the boring machine. The pipe receiving member is adapted to receive and support a pipe section when the pipe handling assembly is retracted such that the auxiliary pipe receiving member is positioned beyond the magazine of the pipe handling device. The auxiliary pipe receiving member is pivotally connected to a lockout assembly that is operable between a closed position and an open position. In the closed position, the lockout assembly prevents a pipe section from entering the auxiliary pipe receiving member. Whereas in the open position, the lockout assembly permits a pipe section to be manually placed in the auxiliary pipe receiving member. Additionally, an axial stop is provided as a mechanical guide for properly aligning the pipe section axially with the magazine.
摘要:
An automatic pipe handling system for automatically transporting pipe sections to and from a horizontal boring machine. The system comprises a pipe handling assembly, a pipe lubrication assembly, a makeup/breakout assembly, and an automatic control system. The pipe handling assembly stores pipe sections and transports the pipe sections to and from the drill string of a boring machine. As the pipe handling assembly transports a pipe section, the pipe lubrication assembly lubricates the appropriate pipe joints. The makeup/breakout assembly secures the drill string and pipe joints so that pipe sections can be added to or removed from the drill string. A programmed controller automatically operates the pipe handling system and its components by synchronizing the operations of the pipe handling system. The controller sequences and times the operation of each aspect of the pipe handling system during both the boring operation and the backreaming operation.
摘要:
A system for monitoring the position and orientation of a downhole tool assembly having multiple beacons. In a preferred embodiment the first and second beacons are supported by the downhole tool assembly. Both beacons are adapted to transmit signals that are indicative of the orientation and position of the downhole tool assembly. A receiving assembly detects the signals transmitted from the first and second beacons. The receiving assembly transmits the detected signals to a processor that processes the signals to produce a composite of the relative positions and orientations of the receiving assembly and the downhole tool assembly. The composite of the relative positions of the receiving assembly and the downhole tool assembly are communicated to the operator using a display. The orientations of the first and second beacons are also communicated to the operator using the display.
