Definitions

  • the present invention relates to apparatus to install structural supports in a mine tunnel and in particular, although not exclusively, to a mining machine mounted assembly having an extendable arm to transport and hold the supports for attachment to the tunnel roof or walls.
  • a mobile tunnel development machine comprises a rotatable cutting head having bits provided on rotating drums to break the rock face.
  • the cutting head is mounted at a movable boom to create the tunnel with the desired width and height.
  • extracted material is gathered by a gathering head and conveyed rearwardly via machine mounted conveying apparatus.
  • WO 2013/110104 describes a tunnelling machine to provide simultaneous erection of a supporting archway structure and cutting of the rock face via a rotating cutting head.
  • Each arch segment is manipulated and held in position by a movable telescopic arm that may be moved in the forward and rearward direction via a rail mounted assembly positioned at the upper region of the self-propelled mining machine.
  • the objectives are provided via the present apparatus in which an extendable roof support manipulator arm and optionally a personnel working platform are movably mounted relative to a fixed base. Accordingly an assembly is provided of reduced weight relative to existing manipulator assemblies that offers a greatly extended range of movement of the manipulator arm. Such an arrangement provides for the efficient and reliable carriage and support of roof and wall lining members. Additionally where the apparatus comprises a working platform personnel are enabled to access a greater range of locations at the raised and forward position of the mining machine in close proximity to the roof and wall where the support members are to be affixed.
  • the objectives are achieved via the mounting of an extendable arm upon a slewing device to allow the extendable arm to conveniently and reliably engage a roof support at the region of the floor of the tunnel and then to carry the roof support in vertical, forward and lateral directions relative to the apparatus so as to bring support at a raised position in contact with the tunnel roof.
  • the extendable arm is accordingly pivotally mounted at the slewing device via one or a plurality of pivot mountings.
  • the extendable arm comprises a gripping device having at least one holding pocket to at least partially receive a portion of the structural support and maintain secure contact with the support as it is transported from a lateral lower to a central raised position above the mining machine.
  • the gripping device may comprise a plurality of holding pockets to grasp independently a plurality of roof supports that may be moved collectively relative to the mining machine.
  • a single extendable arm is beneficial to minimise the overall weight of the apparatus and the mining machine whilst providing a versatile mechanism for lifting and transporting the roof supports within the vicinity immediately surrounding the mining machine including in particular the lateral sides, region above and in front of the mining machine.
  • the extendable arm may also be configured to engage and transport the roof support in the region behind the mining machine.
  • the present apparatus may comprise a support platform that is movably mounted relative to a fixed base via at least one elongate guiderail such that the support platform is capable of moving in a forward and rearward direction along the guiderail.
  • the guiderail via at least one rail mount is cantilevered and slidably mounted at the fixed base. This provides that the elongate guiderail is capable of sliding in a forward and rearward direction relative to the fixed base such that a majority of the length of the guiderail is configured to project forward of the support platform when moved to its axially forwardmost position.
  • Such an arrangement is advantageous to greatly extend the possible range of linear movement of the support platform in the forward and rearward direction.
  • the support platform advantageously provides a mount for the extendable arm and the working platform such that both components may be moved collectively via an efficient linear movement of i) the support platform relative to the guiderail and ii) the guiderail relative to the fixed base.
  • the working platform may be positionable immediately above a forwardmost end of the mining machine corresponding to the rotating cutting head that mounts the cutting bits in a use position.
  • the working platform and manipulator arm may be moved rearwardly so as to be positioned over the mainframe and drive components of the mining machine to protect the manipulator assembly by positioning sufficiently rearward of the cutting head when the machine is operating in cutting mode.
  • the present apparatus therefore is advantageous to avoid damage to the manipulator assembly via its available range of movement.
  • the mine roof and walls may be supported at the position immediately behind the cutting face to significantly reduce the risk of collapse.
  • Versatility of the available positioning of the working platform via the present mounting arrangement provides a safe working environment for personnel in very close proximity to the cut face when installing roof and wall structural supports.
  • apparatus to install a structural support in a mine tunnel comprising: a support platform mounted and configured to slide in a forward and backward direction on a mining machine; an extendable arm, at its one end connected to a gripping device for gripping at least one structural support, in particular a support arch, the arm mounted at the support platform; a slewing device mounting the extendable arm at the support platform to allow the arm to slew outwardly in a sideways direction from the apparatus; the arm being pivotally mounted at the slewing device to enable the gripping device to be raised and lowered relative to the support platform; the gripping device comprises at least one holding pocket for the structural support, in particular the support arch.
  • the arm is telescopic having a head section and an extendable tail section.
  • the extendable tail section further extends the available reach of the arm so as to be positionable immediately behind the cutting face.
  • the apparatus comprises a base to mount the apparatus at a mobile mining machine; the support platform mounted on at least one guiderail and configured to slide in a forward and backward direction along the guiderail relative to the base; and at least one rail mount to slidably mount and allow the guiderail to slide in the forward and backward direction along the base.
  • the arm is advantageously pivotally mounted at the slewing device to enable a grasping end of the arm to be raised and lowered relative to the slewing device.
  • Such a configuration is beneficial to firstly enable the arm to be moved to a substantially horizontal storage position when the apparatus is moved rearwardly during cutting operations and secondly to be tilted or inclined upwardly to position the arm grasping end at a fully elevated position in close proximity to the roof.
  • axis of the slewing device is aligned substantially perpendicular to a pivoting axis by which the arm is pivotally mounted at the slewing device.
  • Such an arrangement is advantageous to optimise the possible movement of the extendable arm such that grasping end is configured to access the majority of the space immediately surrounding the mining machine to engage, transport and hold the support members at a plurality of different positions.
  • the pocket may comprise an elongated form extending substantially transverse including perpendicular, to a main length of the arm.
  • the pocket may be formed as a part cylindrical segment, a cup shaped portion, a body having a channel or trough corresponding in shape and dimensions to a part of the structural support.
  • the at least one holding pocket comprises a plurality of hooked portions that engage spaced apart regions of the structural support so as to stabilise the transport of the structural support.
  • the holding pocket is configured to engage onto an underside and optionally the sides of the structural support so as to not obscure the upward facing surface of the support to allow convenient positioning and securement opposed to the roof.
  • the gripping device is fastened to the arm in a pivotable manner via a hinge.
  • the hinge may comprise a universal hinge such as a ball joint or a plurality of hinges having pivoting axes aligned transverse and/or perpendicular to one another such that the gripping device may be pivoted relative to the arm in a plurality of pivoting axes and directions.
  • the apparatus further comprises an adjustable bracket mounting the working platform at the support platform to allow the working platform to be raised and lowered relative to the support platform.
  • the working platform is mounted to be independently adjustable at the support platform relative to the arm.
  • the bracket is pivotally mounted between the support platform and the working platform to allow the working platform to be raised and lowered above and below a height of the support platform. Pivot joints and couplings provide a reliable means of adjusting the position of the working platform and are suitably robust to withstand the dust and debris laden environment surrounding the mining machine.
  • a distance in the forward and rearward direction over which the support platform is configured to slide on the guiderail is substantially equal to a distance in the forward and rearward direction over which the guiderail is configured to slide on the base.
  • the arm and the platform are configured to move over an extended axial range between the very forwardmost end of the mining machine (above the cutting head) and a region towards the centre of the mining machine for safe storage rearwardly of the cutting head when the manipulator apparatus is not in use.
  • Such an arrangement is also advantageous to install roof supports in close proximity and immediately behind the cutting face to avoid undesirable roof collapse.
  • the apparatus further comprises at least one power operated actuator coupled to the support platform to move the support platform along the guiderail in the forward and rearward direction.
  • the apparatus further comprises at least one power operated actuator coupled to the guiderail to move the guiderail along the base in a forward and rearward direction.

  • Alternative actuators configured to provide the linear sliding movement of the support platform and guiderail and the pivoting action of the bracket may be provided including for example rack and pinion, chain, turnbuckle and pulley or wheel drive arrangements known to those skilled in the art.
  • the working platform is elongate in a widthwise direction across the apparatus such that ends of the working platform extend outwardly beyond respective sides of the support platform.
  • the platform comprises a length sufficient to be positioned under substantially the full length of the beam to provide unhindered access by personnel to manipulate all parts of the beam.
  • the working platform comprises folding or extendable regions such that the platform may be truncated in a storage mode and extended when in use so as to protect the platform when not in use and not to restrict manoeuvrability of the mining machine in the confined mine environment.
  • the working platform comprises a central region being raised above a pair of end regions in the height direction, the central region configured to sit and slide over the guiderail.
  • the working platform allows the working platform to be transported rearwardly over the guiderail such that the side portions are positioned immediately above the roof or canopy of the mining machine to reduce as far as possible the overall height of the machine in certain configurations.
  • a mobile mining machine comprising the apparatus as claimed herein configured to install structural supports within a mine tunnel.
  • apparatus to install structural supports in a mine tunnel comprising: an extendable arm to raise and hold supports at a position at or close to a mine tunnel roof; a working platform to allow personnel to stand on the apparatus at a location close to the arm; a base to mount the apparatus at a mobile mining machine; a support platform mounted on at least one guiderail and configured to slide in a forward and backward direction along the guiderail relative to the base, the arm and the working platform mounted at the support platform; characterised by: at least one rail mount to slidably mount and allow the guiderail to slide in the forward and backward direction along the base.

In the fully extended position the guiderail is cantilever mounted at the base via a plurality of guiderail support mounts.
  • the apparatus comprises at least two and preferably at least four support mounts positioned approximately at each corner of the base so as to provide an effective cantilever mounting of the guiderail. Accordingly, the weight of the support platform, the extendable arm and working platform may be transferred reliably by a guiderail to the underlying base when moved to it fully forwardmost position.

  • Canopy 600 is positioned at a generally forward region of machine 100 immediately above a rearward end of gathering head 103.
  • manipulator assembly 109 located at its rearward position of figures 6 and 7 , canopy 600 is accordingly exposed with arm 110 positioned substantially above the rearwardly projecting discharge conveyor 108 axially rearward of motor 106. Accordingly, in this position, manipulator assembly 109 does not restrict the pivoting movement of boom 104 to allow cutting head 105 to be raised and lowered during cutting operations. Additionally, platform 112 and arm 110 are maintained rearward of any material dislodged from the cutting face.
  • the distribution of the weight of assembly 109 is also fully adjustable via the present arrangement so as to minimise fatigue of the machine 100 generally and those components 601 that support the assembly 109 via mainframe 101.
  • the support platform 305 and in particular arm 110 and working platform 112 may be displaced in the linear forward direction involving sliding movement of the guiderail 301 on base 300 and the corresponding sliding movement of support platform 305 on guiderail 301.
  • Arm 110 may then be slewed in the lateral outward direction such that grasping end 113 is extended laterally outward in the widthwise direction beyond tracks 107 to take hold of support beam 111.
  • Arm 110 may then be raised vertically via pivoting about axis 406 to allow support beam 111 to clear the working components of machine 100.
  • the present assembly 109 therefore provides a linear telescopic arrangement to maximise the axial displacement of arm 110 and platform 112.
  • linkage 314 may then be pivoted so as to project generally downward from support platform 305 to lower working platform 112 downward towards boom 104 and cutting head 105.
