Abstract
Abstract Auger apparatus, such as a coal mining machine, adapted to utilize one or more augers each formed of a string of auger sections of a diameter falling in a wide range. The disclosed apparatus comprises hoist apparatus for hoisting one auger section, or simultaneously a plurality of auger sections, to lift them from a storage rack at a side of the machine and place them in the auger strings or to remove them from the auger strings and place them in the storage rack. Such hoist apparatus comprising rails extending transversely of and above the direction of the augers in the machine, a bridge that travels on the rails, a trolley that travels on the bridge, and a lift member on the trolley that is adapted to be moved in an upright path relative to the trolley, the lift member having tongs at its bottom which may be adapted to grasp one auger section, or which may be adjusted as to number and spacing to grasp simultaneously a plurality of auger sections in predetermined spaced relation, so that the auger sections may be placed in the machine in the proper position with essentially no longitudinal or lateral movement relative to the trolley when it is properly positioned over the auger string or strings in the machine to locate accurately the sections in the machine so they can be automatically connected to the driving chucks of the machine and to other auger sections, and accurately to remove them from the machine and place them in a storage rack in positions where they may again be lifted and placed in the machine. The hoist apparatus makes it possible to use the auger machine to drill at substantial angles from the horizontal, because it can support the auger sections so they do not swing out of position when the machine is at an angle. The apparatus also includes a driving power train in which one or two auxiliary powertrain boxes are provided, two auxiliary boxes being used when two or more augers are to be driven, and one auxiliary box being used when only one auger is to be driven. The apparatus as a whole can be substantially shorter and closer to the ground than the apparatus of this type heretofore used, which required less excavating of the ledge adjacent the wall in which drilling is to occur, and makes possible easier transportation. The hoist apparatus provides increased safety for operators and makes possible the reduction in the number of operators needed to operate the machine.
