Definitions

  • the present invention relates to a guard for covering a chain disposed laterally along the side of a mining conveyor, and more particularly to an improvement in a mining arrangement including a mining conveyor having a drive chain disposed along one side thereof with a drive chain guard housing enclosing such drive chain, the improvement contemplating means for attaining ready access to the drive chain normally covered by the guard housing.
  • Mining conveyors which normally comprise mining conveyor sections articulatedly interconnected longitudinally in end to end relation with means for advancing the conveyor progressively toward the mine face as the mining planer usually disposed for movement along the mine side of the conveyor is displaced back and forth along the mine face in extractive engagement with the mine face for the winning of mineral such as coal therefrom.
  • the mineral is conducted during the operation onto the conveyor for removal from the site of mining operations.
  • a drive chain is utilized either at the side of the conveyor adjacent the mine face or at the side thereof remote from such mine face, i.e., the working side, where access may be had by the workmen to the equipment being utilized.
  • the drive chain is normally mounted at the ends of the conveyor in the form of an endless drive chain or cable, or the like, over appropriate sprocket wheels energized to drive the chain alternately in both directions to achieve the movement of the mining planer back and forth along the mine face.
  • US Patent 2,745,651 concerns a mining planer of the type having a keel extending under the conveyor for stabilizing the position of the planer during mining operations with the drive chain being located on the mine face side of the conveyor. Means are shown which are at tached to the side of the conveyor remote from the mine face for advancing the conveyor progressively toward the mine face as mineral, such as coal, is progressively extracted.
  • US. Patent 2,691,514 shows another arrangement of a mining conveyor and mining planer of the type having a keel underlying the conveyor as well as means for advancing the conveyor toward the mine face.
  • sprocket wheels are shown over which the drive chain for the planer is mounted to achieve the back and forth movement of the planer.
  • the drive chain in this instance is also disposed along the mine face side of the conveyor.
  • US. Patent 2,781,888 shows another form of mining conveyor having means for advancing the conveyor toward the mine face, and illustrates a particular embodiment for achieving articulated interconnection for individual conveyor sections whereby the conveyor may be advanced more or less section by section toward the mine face as the planer executes the back and forth movement in extractive engagement with such mine face.
  • the drive chain on either side of the conveyor for suitable attachment with the mining planer and an alternate expedient is to provide a drive chain having one strand on the mine face side of the conveyor and the other strand on the remote side of the conveyor with suitable sprocket wheel mounting of the chain at the 'ends of the conveyor so as to achieve the desired movement of the planer. It will be appreciated, however, that because of the excessive tension under which the chain is operated, the latter arrangement is not usually preferred since it will cause unnecessary friction at the points of articulated connection between the mining conveyor sections, and of course less free working space for the workmen is present where the drive chain is disposed with strands on both sides of the conveyor.
  • FIG. 1 is a perspective view of the guard in accordance with the invention with the window opening exposed as seen from the working face side of the conveyor, i.e., the side remote from the mine face, with a part of the conveyor being shown as well, and
  • FIG. 2 is a perspective view of the cover plate used to close oii the window opening of the guard of FIG. 1.
  • a chain guard housing for a drive chain displaceable along a longitudinal path which in its broadest aspects comprises longitudinally extended channel means having lateral edges as well as a longitudinal channel groove defined therealong for receiving therein the drive chain for displacement therealong, means defining a slot opening extending from one of the lateral edges medially into the channel means for exposing the adjacent portion of the channel groove, and a cover removably disposed across the slot means for removal to provide thereat working access to the channel groove and in turn the adjacent portion of the drive chain enclosed by the housing.
  • mounting means for mounting the channel means on a backing support are also contemplated whereby a drive chain disposed for travel along such backing support may be protectively shielded by the chain guard housing of the invention, yet with the provision for access to the chain in a simple and reliable manner for the purpose of tending to the chain to mend the same, for example.
  • the present invntion concerns an improvement in a mining arrangement including a longitudinally extending mining conveyor adaptd to be positioned along the mine face to be worked, with a drive chain positioned along one side of the conveyor for displacement longitudinally therealong, a chain guard housing for the chain and mounting means mounting the housing on said one side of the conveyor, such improvement comprising the provision for such chain guard housing in the form of longitudinally extending channel means having lateral edges as well as a longitudinal groove defined therealong for receiving therein the drive chain for displacement therealong, the longitudinal groove facing said one side of the conveyor and the lateral edges extending toward said one side to close off substantially the groove, means defining a slot opening extending from one of the lateral edges medially into the channel means for exposing the adjacent portion of the channel groove, and a cover removably disposedacross the slot opening means for removal to provide thereat access to the channel groove and in turn the adjacent portion of such drive chain.
  • the slot opening means extends medially substantially to the center line of the channel means.
  • the conveyor in the form of a plurality of individual conveyor sections articulatedly interconnected in longitudinal end to end relation, and to provide the channel means in the form of a plurality of channel members disposed in longitudinal end to end relation, with each such channel member being mounted on the appropriate conveyor section on one side of the conveyor and with each channel member having corresponding lateral edges and a longitudinal groove defined therealong for receiving a portion of the chain for displacement therealong.

  • connecting block 22 underlies the conveyor section 13 and is attached at the other side of the conveyor section with the mining planer (not shown) whereby the drive chain (not shown) accommodated in longitudinal groove 23 may be used to conduct the mining planer back and forth along the mine face in dependence upon the force exerted by the drive chain onto connecting block 22 to which the chain ends are connected for normal operations.
  • This arrangement is utilized conventionally, as may be appreciated from a study of US. Patent 2,823,908.
  • the window opening or slot opening 2 which is preferably positioned intermediate the longitudinal ends of channel member 1, is normally protected by a cover 3 disposed thereacross in a removable manner (FIG. 2).
  • Cover 3 in the form of a cover plate of arcuate configuration in conformity with the appropriate configuration of the surounding portions of channel member 1 at slot opening 2 is provided with a pair of spaced apart lugs 6 along the upper edge 4 thereof adjacent the upper edge 15 of channel member 1. Lugs 6 are removably attachingly inserted into the first apertures 14 defined in backing plate 5 so as to shield the space between backing plate 5 and upper edge 4 of cover 3.
  • cover 3 is provided along the lower edge 7 thereof with a pair of spaced apart fingers 8 pivotally mounted at 8' onto cover 3, such fingers 8 being releasably lockingly inserted into the second apertures 9 in the longitudinal reinforcement seating means, such as a flange strip or bar 10, attached to the main wall portion of channel member 1 along the center line thereof at slot opening 2.
  • the mine workmen may obtain access to the chain within groove 23 by merely pivoting fingers 8 out of the second apertures 9 and upwardly tilting cover 3 to draw the lugs 6 out of the first apertures 14.
  • cover 3 Simple removal and reinsertion of cover 3 is thus provided in accordance with the invention and when in place cover 3 is releasably lockingly reinserted sufficiently to shield slot opening 2 against a flying chain in the event of a chain rupture caused by excessive tension and against the undesired seepage of gangue or mineral, such as coal, in small particles or dust form into longitudinal groove 23.
  • the bar 10 serves also to reinforce the portion of channel member 1 adjacent the slot opening 2 together with the vertical reinforcing strips 12, and by the provision for an attachment means, for example in the form of a pivot opening 11, a transverse displacement means, such as a transverse hydraulically operated piston cylinder means, may be connected therewith for displacing the mining arrangement including the particular conveyor section 13 shown laterally in a direction toward the mine face. Arrangements for such conveyor displacement are disclosed in the aforementioned US. Patent 2,745,651, 2,691,514, and 2,781,888.
  • the present invention concerns a guard for covering chains on the working face side of a mining conveyor, in particular, used to drive a mining planer mounted for movement along the mining conveyor, with provision for a window opening normally closed oh. by a cover which is removably attached in a simple manner permitting access to the longitudinal groove and the drive chain in the event the chain must be repaired.
