Definitions

  • ABSTRACT used in coal mines for digging coal.
  • the impact of pressured water against a coal face through the nozzle of the monitor effects the coal digging operationQln working the coal face, coal thrown out from the coal face will clash against the monitor, and falling coal lumps will bury the monitor thus decreasing the efficiency of coal digging operation, and the known type of monitor has suffered damage from such severe conditions.
  • the above impediment has been for the most part eliminated by virtue of the novel constructions wherein the cylinder for raising and lowering the nozzle of the monitor is mounted just behind the monitor while the unit for turning the nozzle of the monitor is disposed under main water supply pipe and is received and closed in a housing.
  • This construction has further advantages in that the full height of the monitor is markedly decreased and in that the stability thereof is greatly increased.
  • a monitor used in a coal mine for digging coal should be constructed as strongly as possible so as to hold up under bad conditions encountered in carrying out coal digging operations. For example, the impact given to the monitor by coal thrown from the coal face will cause damage to the monitor and the falling coal lumps will bury the lower half of the monitor thus hindering prearranged coal digging performance.
  • the above said defects of the conventional monitor are for the most part eliminated by virtue of the characteristic feature thereof wherein the cylinder for raising and lowering the nozzle is provided behind the monitor body while the turning device of the monitor is composed of an assembled rack and pinion, said rack being connected to a piston-rod movable in the cylinder for turning the monitor, said cylinder for turning the monitor being disposed under a main water supply pipe, and said movable members being received and closed in a housing.
  • FIG. 1 is a side plan view showing the example of the monitor for digging coal according to the present invention.
  • FIG. 2 is a top plan view of the monitor of FIG. 1.
  • FIG. 3 is an enlarged elevational view taken on line III-III OF FIG. 1.
  • FIG. 4 is a sectional view taken on line IV-IV of FIG. 3.
  • the monitor according to the present invention comprises a barge-like base plate 1, base frames 2 received in and fixed to said plate 1, a main water-supply pipe having a swivel means therein, a holding means or gripping means 4 which constitutes the joint of said water supply pipe 3, the lower end of the holding means being firmly secured to the base frames 2.
  • the monitor according to the present invention further comprises a tubular member 5 closed at the bottom thereof and rotatably inserted into the holding means 4, a circular water passage 6 formed between the holding means 4 and the tubular member 5, openings 7 bored in the wall of the tubular member 5 for passing water therethrough, a two-way water supply pipe 8 having swivel means which are mounted on the upper end of the tubular -member 5, holding means 9, 9 which serve as joint means, a base tube 10 for mounting a projected delivery pipe thereon, both of the end portions of the base tube 10 being rotatably inserted in the holding means 9, 9, annular water passages 11, openings 12 for passing water therethrough and a nozzle 14.
  • Water under pressure supplied to the main water supply pipe 3 runs into the tubular member 5 through the circular water passage 6 and the openings 7, is split in the two-way pipe 8, after which the water streams meet again at the exit of the base tube 10 through the openings l2 and finally spurt out from the nozzle 14 via the projected delivery pipe 13, thus making it possible to dig coal from a coal face by means of the impact given by the pressured water.
  • the monitor according to the present invention has an arm 15 protruding rearwardly from the center of the base tube 10 and support arm 16, 16 correspondingly protruding from the lower part of the two-way water supply pipe 8.
  • a cylinder 17 for raising and lowering the nozzle 14 is pivotally engaged with the support arms l6, 16 by means of two shafts 18, 18 oppositely fitted to the lower part thereof, and the top of the piston rod 19 is pivotally connected to the arm 15 by means of a pin 20.
  • the cylinder 17 for raising and lowering the nozzle can be disposed behind the body of the monitor.
  • FIGS. 3 and 4 the device for turning the nozzle of the monitor is illustrated.
  • Numeral 21 indicates a fixed shaft located at the center of the bottom of the tubular member 5.
  • a pinion 22 is mounted on the shaft 21.
  • a rack 23 engages with the pinion 22 and one of the end portions of the rack 23 is connected by means of a pin 26 to the top of a piston rod received in a cylinder 29.
  • the cylinder 29 is secured to the base frame 2 and serves to turn the nozzle through the movement of the piston rod 25.
  • the movable members for turning the nozzle are received in and covered by housing members 27, 28 both of which are secured to the bottom of the holding member 4.
  • Numerals 30, 30 indicate packing means.
  • the cylinder for raising and lowering the nozzle of the monitor with the movable members having relation to the cylinder 17 are hidden behind the body of the monitor, and this brings about an important advantage in that the cylinder for raising and lowering the nozzle and the movable members related thereto are protected from the impact of coal lumps thrown out during coal digging operation. Further, since the members movable relative to the cylinder for turning the nozzle are received in and surrounded by the housing member disposed at the lower part of the monitor body, the possibility of falling coal lumps impeding operation is completely eliminated.
  • the main water supply pipe according to the present invention is of the swivel type, and the members for regulating the turning motion of the nozzle, that is, the assembly of pinion, rack, piston rod and cylinder, are
  • a monitor fordigging coal comprising a barge-like base plate, a main water supply pipe secured to said base plate, a tubular member rotatably held by said main water supply pipe, a two-way pipe having two tops and one bottom mounted on said tubular member, a pivotal nozzle member operably connected to said two way pipe and including a nozzle, a first water pressure cylinder for raising and lowering the nozzle of the monitor, said first cylinder being mounted behind said twoway pipe, a shaft projecting downwardly from the bottom of said tubular member, a pinion mounted on said shaft, a rack which engages with.
