Definitions

  • a track supports and guides a bendimparting conveyor carrier vehicle along a path determined to provide flexible hose slack to mining machinery moving along a mine floor.
  • Powered cable means connect the vehicle with an anchor connected to the mine, the cable means cooperating with the mining machinery to position the vehicle relative to a stationary anchor.
  • rigid pipes are laid in parallel juxtaposition to a relay station which provides fluids to the flexible hoses. These parallel pipes are used as the track to support the vehicle.
  • This invention relates generally to improvements in a transportation system involving flexible hoses leading to a moving machine, and more particularly. but not by way of limitation, to an improved apparatus and method of handling the flexible hoses leading to an advancing or retreating mining machine and its accompanying mobile injection station.
  • the mining machine cuts the coal ore from the mine face, then delivers the ore to the mobile injection station, which pulverizes the ore and forms a slurry of the pulverized coal ore with water.
  • the slurry is subsequently piped from near the mining face to a remote processing point, which is usually located outside the mine.
  • the hoses carrying water to the mobile injection station, and slurry therefrom, lead from outside the mine to the mining face via the prepared passageways.
  • at least a portion of the water and slurry hoses comprise flexible hose lines that enable the mining machine to advance or retreat free of the influence of the hoses.
  • the inventors herein have previously suggested the use of a loopor bend-forming conveyor disposed within a lateral passageway and supporting the flexible hoses by a plurality of wheeled carts.
  • the flexible hoses are maintained in the lateral passageway in a manner that takes up the slack of the flexible hoses in an unused portion of the passageway.
  • This method and apparatus is described in the related application as recited above. In the use of this technique of regulating flexible hose slack, there is a need to controllably move the loop or bend-forming conveyor within the lateral passageway of the mine.
  • the present invention contemplates a system for transporting a slurry from the vicinity of a mining machine moving upon the floor of the mine followed by a mobile injection station which is connected to at least one flexible hose that is supported by a plurality of wheeled carts or the like spaced along the length of the hose and pivotally interconnected.
  • the slack in the flexible hose is regulated to the mobile injection station by the provision of an elevating conveyor movably supporting the hose and carts off the mine floor and imparting a bend in the hose, and a vehicle supporting the elevating conveyor is movably supported on track means.
  • a powered hoist and cable means connect to the vehicle and to a stationary anchor point on the mine for moving the elevating conveyor along the track means as required to maintain proper slack to accommodate the advancing or retreating mining machine. It is accordingly an object of the present invention to provide an improved apparatus for regulating the slack and flexible hose connections to a moving machine.
  • Another object of the present invention is to provide an improved apparatus for moving and guiding a bend, imparting carrier vehicle cooperation with an advancing or retreating machine for regulating slack in a flexible hose leading to the machine.
  • Another object of the present invention is to provide an improved apparatus for powering the retreat of a flexible hose leading to retreating mining machinery in a mine passage.
  • FIG. I shows in diagrammatical form the slurry and water transportation system contemplated by the present invention.
  • FIG. 2 is a diagrammatical view showing the operation and layout of the elevating carrier and vehicle of the present invention.
  • FIG. 3 is an elevation of the elevating conveyor and vehicle of the present invention performing the function of imparting a bend in the flexible hoses.
  • FIG. 4 is a plan view of the present invention.
  • FIG. 5 is an elevation of the conveyor carrying vehicle of the present invention having the details of the carrier omitted therefrom.
  • FIG. 6A is an alternative rail layout for the track used in the present invention
  • FIGS. 68 and 6C show another track arrangement.

  • FIGS. 1 THROUGH 5 Referring to the drawings in general, and particularly to FIG. 1, shown therein is a diagrammatical view of the system of mining contemplated by the present invention.
  • the mining machine has previously cut a series of rooms 12, and is in the process of cutting the room 14.
  • the laterals l6 and the entry passages 18 have been cut to gain entry for the mining machine 10, the mobile injection station and the hose 20.
  • Rigid pipes 22 and 24 extend from outside of the mine to a relay station 26 which can serve as a pressure booster station as necessary for the fluids passing through the pipes.
  • Hose is shown as a single hose, but as will be clear below, this is a double hose placed over and under, and which is shown as hose 20 in FIG. 1 for purposes of illustration.
  • Hose 20 is a flexible hose leading from the connection point 28 at the relay station 26 through the lateral passageways l6 and one of the entry passageways 18 to connect at point 30 to the rear of mobile injection station 15.
  • hose 20 is pulled in the direction 32 by the power of the advancing machine 15.
  • machines 10 and 15 In the process of removing coal ore from room 14, machines 10 and 15 must at times move in the reverse direction, whereupon hose 20 must be pulled by other means in the direction 34 in order to regulate the slack of hose 20 to machine 15, and thereby free the machines in their movement relative to the flexible hose.
  • the means of pulling the flexible hose 20 in the direction 34 cooperatively as machine 10 retreats is that a bend or loop 36 is imparted to the flexible hose 20, in the manner described below, and a portion 38 of hose 20 is pulled along the lateral passageway 16.
  • the movement of portion 38 of hose 20 in direction 34 must be performed in cooperation with the retreat of machine 10 in a manner that sufficient hose is provided to the machine without causing excessive pulling action on the machine.
  • portion 38 of hose 20 must be sufficiently moved in direction 34 so as to take up the slack and keep it out of the way of retreating machine 15.
  • FIG. 2 shows a diagrammatical view of loop 36 and of the apparatus of the present invention for moving it along lateral 16.
  • the present invention contemplates the flexible hose 20 being supported on wheeled carts 40 that are interconnected by connecting links 42 which are connected with each other and to the carts by the hinge joints 44.
  • FIG. 3 shows an elevation of some of these carts and links.
  • Carts 40 and links 42 are known in the prior art to this invention, and need not be described in detail herein for purposes of this disclosure. It is sufficient to say that the purpose and arrangement of the wheeled carts 40 and links 42 are such that the flexible hoses 20 are enabled to maneuver in a bending configuration in a generally horizontal plane upon the floor of the mine.
  • the loop 36 in flexible hose 20 is achieved by the use of an elevating conveyor 46 that movably engages carts 40 and links 42, elevates them, transfers them about an arcuate section thereof, and returns the carts and links to the mine floor.
  • flexible hose 20 is supported along its length by the wheeled carts 40, and therefore may be pulled along the mine floor.
  • the elevating conveyor 46 imparts a loop or bend 36 in portion 38 of hose 20.
  • FIG. 4 For an understanding of how the conveyor operates, a plan view is provided in FIG. 4. Conveyors of this type are known in the art and need not be described in detail for the purpose of this disclosure.
  • a conveyor carrier vehicle 54 is provided to support elevating conveyor 46.
  • Vehicle 54 comprises a longitudinal platform 56 having a front portion 58 and a trailing portion 60 connected by V-shaped intermediate portion 63. Connected to the leading edge of front portion 58 is the support cart 64.
  • a support cart 66 of the same design is supportingly attached to the back edge of the trailing portion 60 of the platform 56.
  • the support carts 64 and 66 comprise box member 68 and the track wheels 70.
  • Each pair of wheels 70 are mounted to axles 72 passing through appropriately placed apertures in box 68. It is preferable that each pair of track wheels 70 be spaced apart a distance required to rollingly fit standard width track 74, which comprises a pair of rails 76 placed in parallel juxtaposition on the ties 78.
  • the shape of the wheels 70 and the corresponding shape of the track members 74 are not critical to the invention herein, but may be conveniently selected. However, it has been found in practice that the use of standard width track, which runs between 42 and 48 inches, frequently allows the use of onhand rail stock at the mine. It will be understood that the details of construction of support carts 64 are also not essential to the invention herein. The embodiment of the support carts 64 that is herein shown permits the use of conventional structure for such parts as bearings, braking, and lubrication.
  • skid 84 is attached to the ramp for stabilizing it under the weight of hose 20, carts 40, and links 42.
  • the design of the skid 84 is not critical, as its sole purpose is to provide outboard support to the ramp and consequently to conveyor 46.
  • skid 84 is a configured pipe shaped to have a lower portion 86 making dragging contact with the floor of the mine.
  • Hoist 90 includes a rotatable drum 92 that has an axle 94 bearingly journaled in appropriately placed apertures located in the pair of upright plates 96 extending from surface 88. Although details of construction are not shown, gear means at 98 are provided to selectively turn the drum 92 by means of motor 100.
  • a cable 102 is partially wound on the drum 92 and extends there from through a polished aperture located in the guide 104 located near the center of the forward edge of cart 64 on surface 88.
  • the cable 102 has a hooking member 106 at the end of the cable not connected to drum 92.
  • cable 102 is extended and hooked in the manner shown to an anchor 108 that is securedly attached to the mine.
  • Anchor 108 may be a roof and floor jack of conventional design, or may be a crossjack member placed angularly in known manner across the lateral passageway 16.
  • the form of anchor 108 is not essential to the invention herein and the type of anchor used is left to the discretion of the system operator, as the varying conditions encountered may require.
  • FIG. 6A shows three rails 110 spaced on ties 112 so that the outside rails are maintained a standard distance 113 (42 to 48 inches) from the center rail.
  • FIG. 6B shows three rails 110 spaced on ties 112 so that the outside rails are maintained a standard distance 113 (42 to 48 inches) from the center rail.
  • FIG. 6B shows a pair of standard tracks placed in overlapping juxtaposition such that the standard measurement I20 exists between the rails 114 and between the rails 116, all of which are attached to the common ties 118.
  • FIG. 6C is yet another track arrangement wherein four rails 122, 124, 126 and 128 are a standard distance I30 apart as they are attached to ties I32, providing three pairs of rails; that is, pairs 122, I24; 124, I26; and 126, 128. These are just a few examples of possible rail arrangements, as the possibilities are numerous.
  • hose 20 is pullable on the floor of the mine because of the support given by wheeled carts 40 that are pivotally interconnected by links 42.
  • the hose 20 and supporting apparatus extend from relay station 26 into a convenient lateral passageway 16, and a loop or bend 36 is imparted in portion 38 by means of the elevating conveyor 46 which slidingly elevates a portion of the hose, along with supporting carts 40 and links 42.
  • Conveyor 46 clears the cart wheels off the mine floor, rotates them about its arcuate portion, and replaces the same to the floor of the mine.
  • cable 102 is let out by means of controlling motor 100 via conventional means to unwind the cable from drum 92 to a length sufficient to attach to an anchor 108 that has been securedly connected to the mine for relative immovability.
  • Cable 102 is connected to anchor 108 by looping around and connecting hooking member 106 about cable 102 in the manner shown, or in any convenient manner.
  • the placement of vehicle 54 and tracks 74 are predetermined so as to provide ample space for moving hose 20 so as to take up all of the hose slack in lateral 16 by the proper sizing of portion 38 of the hose 20.
  • the tension in cable 102 may be used to regulate devices of known structure to control the rotation of the drum 92 such that a predetermined tension can be maintained in the hose 20 leading from the bend 36 to machine 15. Further, controlled braking of drum 92 may be incorporated to establish back pressure so as to impart a desired amount of pull, or tension, on hose 20.
  • FIGS. 7 THROUGH 9 An alternative to the use of common rails for track 74 is shown in FIG. 7. Therein is shown rigid pipes 22 and 24 passed through one of the entry passageways l8 and positioned in parallel juxtaposition in the lateral passageway 16, terminating at the station 26, as before.
  • the flexible hose 20 is once again connected to the relay station 26 at point 28.
  • hose 20 is caused to loop back over the pipes 22 and 24 in the lateral passageway 16, and the vehicle 54 is equipped with track wheels that are shaped to ride on the rigid pipes 22 and 24, the pipes thereupon serving as the track 74'.
  • the structure and operation of the present invention is unchanged from the description given above for the embodiment of FIGS. 1 through 5.
  • FIG. 9 An alternate to the powered hoist of the embodiment of FIGS. 1 through 5 is shown diagrammatically in FIG. 9.
  • the cable is connected in endless fashion over the sheaves of pulley blocks and 132 that are conveniently anchored to the mine, or to anchor jacks in conventional fashion.
  • a pair of capstans or drums I34, 136 are connected to one of the support carts 64, and at least one of the capstans is powered to pull the cart along the track 74.
  • Slack in cable 102 is regulated by having one of the drums serve as a take-up or wrapping drum. Disengagement is achieved by providing appropriately spaced apart cable connection joints.
  • Other alternative powered arrangements include, but are not limited to: two powered hoists, each to pull the conveyor vehicle 54 in one direction, and attached to the support carts 64, or remotely located with a cable attachment to the carts; rail wheels that are powered, for example by small motors disposed in carts 64.
