Definitions

  • Coal ploughs which are chain-driven along a guide rail.
  • the guide rail bears with its outer edge on the mine oor and on the coal face and forms a covering for a passage in which the chain which pulls the plough passes.
  • a passage in which the chain which pulls the plough passes.
  • the passages are usually covered by a hoodtype plate on the coal face side, which plate is connectable through and with the distance piece by means of bolts or screws which join the conveying means, the distance pieces and the hood.
  • Another object is to provide a plough guide adapted to house chain drive passages so constructed as to provide good accessibility to both chain passages, whereby tting, dismantling or repair of the chain is readily possible.
  • one aspect of this invention resides in a guide for a plough of the type described above, wherein the mine-face directed hood or cover for the chain passages is articulatably hinged to the back plate of the guide means along the top hereof.
  • the hinge is formed as a tubular guide rail for the plough, extending over the length of the working range of the plough.
  • This tube-type guide rail constitutes the upper enclosure of the upper chain passage, so that the plough can rest on it. At the same time, the plough can grip over this guide rail with an extension directed towards the goat ⁇ side, and thus is non-tiltably guided.
  • This guide rail as a hinge renders it possible now for the cover plate to be turned over completely to the goaf side, so that both the upper and the lower chain passages are exposed. To permit hinged articulation, it is only necessary to first release the outer nuts from connecting .bolts or screws and then carry out the hinge movement.
  • the lower chain passage is covered on the mine face side thereof by a tube extending over the working range of the plough.
  • This tube is advantageously adapted to take up the forces occurring in the region of the guide blocks.
  • the hinge bolt of the tubular guide rail can be made fast by means of a clamping sleeve.
  • two opposite openings are provided in the wall of the tubular guide rail to receive a clamping sleeve.
  • One of the openings is circular, and the other is an elongated hole. If the clamping sleeve has been driven in through the guide tube in the direction towards the elongated hole by an amount corresponding at least to the thickness of the Wall of the giant tube, the hinge bolt can be displaced so far in an axial direction that the entire covering hood can be removed should the need of such removal arise.
  • the web plate is advantageous to provide a web plate attached to the cover plate on the side thereof directed away from the mine face in the vicinity of the bolt and the distance pieces.
  • the web plate is further attached to the lower tube referred to above and serves both as a bending-resistant connection between the cover plate and the lower tube and as a means for the connection of the cover plate with the distance piece.
  • the web plate possesses bores adapted to engage a tapered washer which Washer acts to center the connecting screw or bolt.
  • FIG. 1 is a side elevation partially in section through the guide according to the invention.
  • FIG. 2 is a front view of the cover plate, seen from the coal face.
  • a plough is shown fastened to a conveyor 26 and to a plough guide.
  • the lower part of the plough guide comprises a rail 2, which bears with its outer edge 3 on a mine lloor 4 and on a coal face 5.
  • a chain passage 7 is shown, containing a pulling run of chain 6 and a chain passage 9 is shown contaming a return run of chain 8.
  • Distance pieces r spacers 10 are provided between the two chain passages, which distance pieces are attached, by bolts 12, both with the plough guide and with the conveyor 26.
  • a hood like plate 11 is provided on the coal face side of the plough guide.
  • the plate 11 has, at its lower outer edge, a tube 17 and, at its upper outer edge, a tubular guide rail 15.
  • the upper guide rail is hinge 14 and has a plate 13 articulated therefrom which forms the goat-side enclosure of the chain passages 7 and 9.
  • the individual sections of the cover plates 11 are connected by hinge bolts 16 which can be made fast by clamping sleeves 18.
  • the clamping sleeves here engage through a circular opening 20 provided in a wall 19 of the guide rail and an opening 21, formed as an elongated hole, which lies opposite to this circular opening 20.
  • a coal plough assembly having a coal plough means and a guide rail assembly operatively associated therewith, which guide rail assembly contains two passages therein adapted to house pulling and return run chain means respectively, which pulling run chain means is operatively connected to said plough means; the improvement which comprises providing said return run chain passage above the pulling run chain passage and said hinge/guide rail extends the length of said plough means.
  • the improved assembly claimed in claim 1 including hinge bolt means associated with said hinge/guide rail and clamping sleeve means adapted to make said hinge bolt means fast.
