| 摘要 | The invention relates to a lift assembly carrying a drift mining equipment for driving raises and the like in rock. The equipment comprises a fluid motor unit for moving said equipment along a guide track composed of a plurality of separate sections which are adapted to be spliced on successively as the raise driving work proceeds, and to be secured, each in its turn, to the wall of the raise from a platform or the like forming part of the drift mining equipment. A drive unit comprising an internal combustion engine assembly and fluid pumping means operated by said engine is suspended so as to be pivotable about a substantially horizontal axis extending transversely of said track, and is associated with the drift mining equipment to be moved together with the latter along the track in a position such that the internal combustion engine assembly will function independently of the inclination of the raise relative to the horizontal plane, said fluid pumping means being interconnected with the fluid motor unit by flexible fluid conduits. The invention eliminates the need of power supply lines extending along the raise for propulsion of the drift mining equipment along the track. | ||||||
| 权利要求 | 1. Drift mining equipment for driving raises and like drifts in rock, comprising a. track means composed of a plurality of interconnected but separately demountable track sections; b. means for securing said track sections to the wall of a raise; c. frame means carrying platform means; d. guide and support means for suspending said frame means for reciprocating movement on and along said track means, said guide and support means further carrying fluid motor means for driving said frame means along said track means; e. a drive assembly including internal combustion engine means, a fluid pumping means operated by said engine, and conduit means for directing drive fluid from said fluid pumping means to said fluid motor means, and f. means for suspending said drive assembly from said guide and support means so that the drive assembly is freely pivotable about a substantially horizontal axis extending transversely of said track means; whereby said internal combustion engine means will always be able to take a position in which it will function regardless of the inclination of the raise. 2. Drift mining equipment according to claim 1 wherein the means for suspending said drive assembly is a framework which has one section that is movably supported from the track means and a second spaced apart section that is pivotably connected to said guide and support means about a horizontal axis extending transversely to the track means. 3. Drift mining equipment according to claim 1 wherein said fluid motor means consists of a hydraulic motor of the axis-piston type, the fluid pump means is a variable axial-piston pump and the drive assembly includes a hydraulic-fluid reservoir. 4. Drift mining equipment according to claim 1 wherein said fluid motor means and said fluid pump means are a pneumatic motor and a pneumatic pump, respectively. 5. Drift mining according to claim 1 wherein said internal combustion engine means is a diesel engine. |
