Definitions

  • 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.
  • the present invention relates to a lift assembly carrying a drift mining equipment for driving raises and the like in rock, said drift mining equipment comprising 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.
  • raise lifts of the kind here disclosed are well-known to those skilled in the art and offers a number of advantages over previous methods, first of all owing to the fact that raise lifts enable a substantially faster driving rate.
  • raise lifts For driving small raises, ofa length of 150 m, at most, lifts operated by pneumatic motors are most commonly used, whereas for raises of greater lengths electrically operated lifts are employed. The latter, however, are restricted in use to raise lengths of about 600 m. At greater lengths excessive problems are encountered as regards the electric cable required for operating the motors.
  • raises or drifts up to 1000 m and more in length are becoming increasingly common.
  • the invention has for its object to provide an improved raise lift enabling driving raises of the greatest lengths encountered and without any problem as regards power supply.
  • the lift assembly according to the invention is characterized in that 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.
  • the raise in this case, can be driven in any inclination between horizontal and vertical positions, owing to the fact that the positional sensibility of the internal combustion engine has been eliminated by the pivotal suspension of the drive unit.
  • the latter in order to enable satisfactory operation of an internal combustion engine, the latter must be maintained in a fixed position relative to a vertical plane.
  • the drive unit is carried in spaced relation to the guide track and to the drift maining equipment so as to be pivotable about a first horizontal axis extending transversely relative to the track, by being suspended from a framework which, at two locations relatively spaced along the track, is movably supported from the track at one of said locations and is pivotally connected with the drift mining equipment, respectively, at the other location so as to be pivotable about a second horizontal axis extending transversely relative to the track.
  • the pivot axis of the drive unit can be fixed at a substantially constant distance from the track, which distance is merely sufficient to allow for any required inclination or change in inclination of the-track without any risk of the drive unit impinging the track.
  • a limited floating will be allowed as between the drive unit and the comparatively bulky drift mining equipment, so that the entire assembly composed of this equipment and the drive unit can be bodily moved, for instance, along a horizontally extending section of the track to and along a substantially vertically extending section thereof, without requiring for the drive unit at any time any substantially larger cross-sectional space within the raise than that required for the drift mining equipment, and without impinging the latter.
  • Said framework in addition, suitably carries a fuel reservoir for supplying the internal combustion engine assembly.
  • the fluid motor unit is constituted by a hydraulic motor of the axial-piston type
  • the fluid pumping means is a variable-throw axial-piston pump, in which case the drive unit, in addition, comprises a hydraulic-fluid reservoir.
  • the fluid motor assembly and the fluid motor pump are The fluid motor assembly and the fluid motor pump,
  • .internal combustion engine assembly is, preferably, a
  • FIG. 1 is a side elevational view of a raise lift constructed according to an exemplary embodiment of the present invention
  • FIG. 2 is a cross-sectional view as seen in the direction of arrows IlII in FIG. 1;
  • FIGS. 3 and 4 are diagrammatical side views illustrating how the raise lift of FIG. 1 can assume different attitudes according to the inclination of the raise of drift.
  • each track section is secured to the rock wall by a sowel bracket 8, and each section, in addition, is supported at its lower end by the top of the next-preceding mounted track section.
  • Each track section is built up of a track element proper, 10, in the form of a channel member provided with a toothed or pinned rack, and a set of pipe lines 12.
  • the pipe lines 12 are adapted to convey pressurized air for the drilling assembly, as well as water for the drift mining equipment moved along track 4, as will be further described hereinafter.
  • the drift mining equipment briefly, comprises an operating platform 14 and a lift cage 16 which are mounted to a framework, as indicated at 18.
  • the operating platform,l4- is pivotally mounted to the framework 18 in a manner not specifically illustrated and is adjustable into a horizontal position independently of the inclination of the raise or drift by means of an adjustment device 20 in the form of two telescopically interconnected tubes, the upper tube, at its extreme end, being pivotally connected to the platform 14 at 22, and the lower tube, at its extreme end, being pivotally connected to the framework 18 at 24.
  • the lift cage 16 serves for carrying personnel to the working place within the raise and is provided in its top portion with a door, not shown, to enable the operators to climb to the platform 14, the cage having, in addition, in its floor a door serving as an emergency exit.
  • the framework 18 is guided and supported on the track element by roller sets, not shown in detail, and is movable along the track by a machinery comprising two worm gears 26 driving individual toothed wheels, respectively, which are in mesh with the pinned rack of track element 10.
  • the input element of each worm gear 26 is drivingly connected to a drive unit to be further described hereinafter.
  • the machinery in the embodiment illustrated by way of example, further comprises a centrifugal brake unit indicated at 28 and an automatic speed limiter or capture device indicated at 30.
  • Numeral 32 designates a synchronizing coupling interposed between the two worm gears 26.
  • the arrangement so far described is a conventional raise lift with its associated, also conventional equipment.
  • the raise lift is well known to those skilled in the art and therefore need not be further described here, neither in its functional nor as to its structural features. Thus, for instance, it could correspond essentially to a raise lift of the type ALIMAK STH-S.
  • the input element of the two worm gears 26 are driven in common by a hydraulic motor 34 of the axialpiston type, which, again, is mounted on the framework 18 in a manner not illustrated in detail.
  • Motor 34 has hydraulic fluid supplied to it from a diagrammatically illustrated drive unit 36 through supply lines omitted from the drawing for clarity.
  • Drive unit 36 comprises a box-shaped casing containing a drive assembly consisting of a diesel engine, for instance of 39 HP, and a variable axial-piston pump driven thereby.
  • the axialpiston pump is adapted to feed hydraulic fluid to the motor 34.
  • Both the diesel engine and the axial-piston motor may be of any commercially available design and, therefore, need not be further described here, either.
  • the box-shaped casing of drive unit 36 also contains a hydraulic-fluid reservoir with a capacity of 25 liters, for example, and a starter battery having a capacity of l 10 Ah.
  • the suspension for the drive unit 36 comprises a frame consisting of two parts rigidly connected with each other.
  • the first one of these parts is a T-shaped frame member 37 having the free extreme end of the leg of the T pivotally connected to the framework 18 at 38, so as to be movable about a horizontal axis extending at right angles to the track 4.
  • the leg of frame member 37 at its end remote from suspension point 38 is rigidly interconnected with a second frame member 39.
  • Frame member 39 consists of a pair of spaced parallel bars 39a and 39b extending at right angles to, and on either sides of the track 4 and carrying a plurality of guide and supporting rollers 40 adapted to run on the flat surface of the track element 10 in the manner indicated in FIGS. 1 and 2.
  • suspension arms 42 carry between them the box-shaped casing of the drive unit 36, so that the latter is pivotally suspended about a horizontal axis 44 extending at right angles to the track.
  • the T-shaped frame member 37 may suitably be built up of hollow beam members so as to form a fuel reservoir for the diesel engine.
  • the supply conduit from this reservoir is omitted from the drawing for clarity.
  • the pivotal suspension of the drive unit 36 as illustrated and described hereinbefore enables this unit always to occupy one and the same position or attitude relative to the vertical, independently of the inclination of track 4 and without impinging track 4, frame portions 37, 39 or lift cage 16 at any time. Furthermore, the suspension is so devised, that the drive unit 36 will at worst take up merely a slightly larger space within the cross sectional area of the raise than the remainder of the drift mining equipment, including the platform 14 and lift cage 16.
  • FIG. 3 illustrates the positional relationship of the drift mining equipment and drive unit 36 where the track 4 extends horizontally
  • FIG. 4 illustrates the drift mining equipment and the drive unit 36 in transferring from a substantially horizontal or slightly upwardly inclined portion of track 4 to a vertically extending track portion which is ascending into a vertical raise.
  • a raise lift equipment constructed in accordance with the present invention will be entirely independent of any electrical lines extending backwards through the raise, as opposed to electrically powered raise lifts, and of any pressurized-air conduits, as opposed to pneumatic-motor driven raise lifts. This will enable very long raises, of lengths up to 1,000 meters or more, to be driven rapidly and economically.
  • 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;
  • 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;
