Definitions

  • Each housing e1ther supports, or 15 connected to, a [521 LS CL 61/45 D telescopic prop which enables the housing to be [51] Int. CL 29/02 clamped in a fixed position-
  • Each housing contains a [58] Field 299/31 piston and cylinder unit having its cylinder connected 299/32 198/126 to a slide member guided for movement between two resilient guide rails. Two end plates connect to the [56] References Cited beam, possible via articulated joints, and extend through recesses in the housings.
  • Each end plate is UNITED STATES PATENTS connected to the slide member in the associated Spragg D X housing o that conveyor can be tensioned i s i2 extending the piston and cylinder units to displace the osen erg e a. 1
  • mining apparatus comprising a beam for supporting a drive unit of a conveyor, a clamping assembly operably connected to one end of said beam, said assembly having a housing which is adapted to adopt a fixed position and means within said housing for displacing said beam in relation to said housing. By displacing the beam the conveyor can be subjected to tension.
  • the aforesaid clamping assembly is connected to each end of the beam and a prop is supported by the housing of each clamping assembly.
  • the prop enables the housing to adopt a fixed position. This arrangement provides a particularly compact apparatus.
  • the means for displacing the beam is preferably in the form of a piston and cylinder unit.
  • the cylinder of the unit is connected to a slide member guided between two resilient guide rails in the housing.
  • the beam is connected indirectly to the slide member and the resilience of the guide rails tends to maintain the correct positional relationship between the beam and the housing.
  • the prop is supported on a base plate itself connected to the housing via an articulated joint.
  • FIG. 1 is a plan view of one form of mining apparatus made in accordance with the invention.
  • FIG. 2 is an enlarged part-sectional plan view of part of the apparatus shown in FIG. 1;
  • FIG. 3 is an end view of part of the apparatus shown in FIG. 1;
  • FIG. 4 is a plan view of a further form of mining apparatus made in accordance with the invention.
  • FIG. 5 is an end view of part of the apparatus shown in FIG. 4.
  • a main drive unit for a coal-face conveyor is supported on a support member 11 slidably guided on a beam 12.
  • the conveyor extends generally perpendicularly to the beam 12.
  • the unit 10, in conjunction with the member 11, can be moved along the beam 12 by operating a hydraulic piston and cylinder unit 13.
  • the cylinder of the unit 13 is connected to an abutment member 14 which can be locked in position relative to the beam 12.
  • the abutment member 14 is slidably guided on the beam 12 for adjustment purposes and can be moved along the beam 12 when the associ ated locking mechanism is released.
  • each plate 16 is operably associated with a clamping assembly having a housing 17 in which is disposed a hydraulic piston and cylinder unit 18 (FIG. 2).
  • the plate 16 extends through a pair of recesses 32 provided in the longitudinal side walls of the housing 17.
  • the recesses 32 are partly closed by closure members 33 which fit around the plates 16 and are arranged to move with the plates 16.
  • the members 33 are designed to close the interior of the housings 17 regardless of the particular position of the plates 16.
  • the piston rod of each unit 18 is connected via a vertical pin 19 to the associated housing 17.
  • the cylinder of each unit 18 is connected via a pin 20 to a slide member 21 slidably guided between two resilient guide rails 22.
  • the member 21 is connected to the associated plate 16.
  • One end 24 of each rail 22 is rigidly connected to the associated housing 17 whereas the other end 23 of each rail 22 is movable in relation to the housing 17.
  • each clamping assembly At the upper side of each clamping assembly a stay prop is hinged to the upper face of the housing 17 by means of a horizontal pin 25.
  • Each prop 26 has an upper part 27 which can be extended to engage the roof of a mine working to cause the housing 17 connected thereto to be fixed in position.
  • Each prop 26 is forced to assume an inclined disposition by means of a spring arrangement 28 and the position is rendered adjustable by the provision of an adjustment device 29.
  • the apparatus as described is intended primarily for use at a lower level of a mine working. The operation of the apparatus is as follows:
  • FIGS. 4 and 5 An alternative construction is shown in FIGS. 4 and 5 where like reference numerals are used to denote like parts.
  • the props 26 are each supported on a base plate 30 engaging directly on the floor of the working.
  • Each base plate 30 is connected to the housing 17 of the associated clamping assembly via articulated connection links 15 having pivot pins 31.
  • the beam 12 is directly connected to the end bars 16 in contrast to the construction shown in FIGS. 1 to 3.
  • the constructions shown in FIGS. 4 and 5 is intended primarily as an auxiliary drive at an upper level of a mine working.
  • Mining apparatus comprising:
  • each said connecting means at least includes an articulated joint.
  • each said clamping means is in the form of a telescopic prop supported by said housing.
  • each said clamping means is in the form of a telescopic prop supported on a base plate, said base plate being connected to the associated housing via an articulated joint.
  • each housing has recessed walls and a plate extends through said recessed walls, the plate being connected to the beam for movement therewith and wherein said recesses are substantially closed by closure members movable with said plate.
