Definitions

  • the present invention relates to a tunnelling or extraction machine comprising cutting tools, which are movable over the heading face and are arranged on a boom, and a platform which is movable in the longitudinal direction of the machine and carries roadway support devices.
  • An anchor-boring and anchor-setting device arranged on a sliding track is known from AT 502 047 A4, in which an additional manipulator for lifting and for mounting covering mats is fastened to a rollover of the anchor-boring and anchor-setting device.
  • An embodiment of a support device having two anchor-boring and anchor-setting devices which are pivotably supported on an anchor platform which is movable in the longitudinal direction of the machine is the subject matter of AT 413230 B.
  • DE 29 34 625 A1 discloses a combination of a tunnelling machine with support devices, in which a support manipulator is fixed onto a sliding track, so that pre-assembled support arches can be conveyed along the tunnelling machine and positioned in the roadway in the front area of the tunnelling machine.
  • a revolving crane is used which is fixed onto the rear side of the tunnelling machine for lifting up the pre-assembled support arches and for transferring to a support manipulator which can be moved on the sliding track.
  • a further example for a support manipulator which can be moved on a sliding track can be learned from DE 29 08 452 A1.
  • the described embodiments relate to the providing of individual roadway support devices in connection with a tunnelling machine, whereby although a specific operation within the scope of the roadway support process can be mechanised and efficiently designed, manual operations are still necessary.
  • the described embodiments relate to multi-functional solutions (e.g. AT 507495 A1), which although they are versatile in their use, in individual cases modifications have to be made, which makes a mechanised method of operation difficult.
  • the invention therefore aims to develop a tunnelling machine with integrated roadway support devices further, to the effect that the degree of mechanisation can be considerably increased for a combined roadway support process.
  • the individual support devices should be able to be positioned on the tunnelling machine such that the lowest possible headway can be achieved.
  • the invention essentially makes provision for the roadway support devices to comprise a support manipulator and an anchor-boring and anchor-setting device, wherein the anchor-boring and anchor-setting device is fastened to the movable platform in a pivotable manner between a parked position and an operating position and the support manipulator has a telescopic arm which is fastened to the movable platform in a vertically pivotable manner and which carries a gripping device for temporarily taking at least one support element, in particular a support arch, wherein the support manipulator and the anchor-boring and anchor-setting device are fastened to the movable platform at a predefined, fixed distance apart from one another and are displaceable together with the movable platform between a retracted position and a forwardly displaced position.
  • the anchor-boring and anchor-setting device being pivotably arranged between a parked position and an operating position, the anchor-boring and anchor-setting device can be placed out of the way during heading to save space without hampering the cutting process.
  • the anchor-boring and anchor-setting device In the parked position, the anchor-boring and anchor-setting device is preferably folded-up flat on the movable platform.
  • the support manipulator or the supporting device having a telescopic arm which is fastened to the movable platform in a vertically pivotable manner, for heading, the support manipulator or the supporting device can be pivoted downwards onto the movable platform, in order to thereby minimise the space taken up.
  • the telescopic vertically pivotable arm of the support manipulator according to the invention has a gripping device, by which the individual segments or already screwed together multiple segments of the support elements, in particular support arches, are held and brought into the installation position.
  • the gripping device along with the support element temporarily held in the gripping device can be precisely positioned.
  • the support element is mounted as a rule from the bottom up, wherein firstly the props are positioned and the support arch is connected to the previous support arch via spacer bars.
  • the operating position of the anchor-boring and anchor-setting device relative to the support manipulator is in particular chosen such that anchors can be set in the area of the vertical plane defined by the support element positioned by the gripping element.
  • the operating position of the anchor-boring and anchor-setting device relative to the supporting device is chosen such that anchors can be set in the area of the roof supported by the supporting device.
  • a preferred further embodiment makes provision for the supporting device to have a supporting plate which can be pressed against the roof.
  • a preferred further embodiment makes provision for the operating position to be chosen such that the anchor-boring and anchor-setting device and the supporting device in the operating position become effective in an area of the roof located in front of the cutting tools.
  • the mechanisation of the roadway support process can be further improved by the roadway support devices further comprising a lifting crane which has a telescopic jib rotatable about a horizontal rotational axis.
  • the lifting crane is preferably fastened to the movable platform at a predefined, fixed distance from the support manipulator or supporting device.
  • the movable platform carries all essential roadway support devices required for the roadway support process, namely the lifting crane, the support manipulator or the supporting device and the anchor-boring and anchor-setting device.
  • the roadway support process is preferably carried out in such a way that the lifting crane in the retracted position of the platform firstly grips at least one roadway support element, lifts it up, conveys it forwards by pivoting the crane jib and deposits it in a holding device of the gripping device. Then, the movable platform is forwardly displaced and the at least one support element is pressed onto the roof by means of the telescopic arm of the support manipulator.
  • a preferred further embodiment makes provision for the gripping device to comprise at least one, preferably two, holding pocket(s) for a support element in each case, in particular for a support arch.
  • the gripping device can comprise at least one, preferably two, holding pocket(s) for a support element in each case, in particular for a support arch.
  • two support elements in particular support arches, can consequently be brought into the assembly positions at the same time, so that the speed of the roadway support process can be increased.
  • the desired distance between two consecutive support elements is predefined by the distance between the two holding pockets.
  • the gripping device comprises a carrying device, which in particular is arch-like, for temporarily taking a covering mat, at the same time, a covering mat can be positioned by the gripping device or the support elements pressing onto the roof, so that immediately after that the anchor-setting process can be begun.
  • the platform In order to increase the stability of the platform, provision is preferably made for the platform to be supported in the upwardly displaced position on a support arranged on the boom.
  • Pivoting of the anchor-boring and anchor-setting device between the parked position and the operating position and the degree of freedom required for setting the anchors in the entire roadway profile are particularly easily achieved in terms of design by providing a pivoting device for pivoting the anchor-boring and anchor-setting device between the parked position and the operating position, on which pivoting device a rollover is arranged, by means of which the anchor-boring and anchor-setting device in the operating position is pivotable about a rotational axis running in the longitudinal direction of the machine. It is particularly advantageous here if the pivoting device is arranged on the front end of the movable platform. This enables the rollover or the anchor-boring and anchor-setting device to be pivoted beyond the front end of the movable platform downwards into the operating position, so that the most central positioning possible is obtained of the anchor-boring and anchor-setting device within the roadway profile.
  • the embodiment is preferably further developed in such a way that the pivoting device has at least one supporting prop which is extendable against the floor in the operating position of the anchor-boring and anchor-setting device.
  • the anchor-boring and anchor-setting device In order to make operation of the anchor-boring and anchor-setting device easier for operating personnel, provision is preferably made for work platforms to be arranged on the movable platform on both sides of the longitudinal centre plane of the machine.
  • the respective work platforms can be lowered and lifted by means of a lowering and lifting device relative to the movable platform.
  • Particularly stable platform guidance is advantageous considering the forces acting on the roadway support devices during the roadway support process. According to a preferred further embodiment, this is achieved by the movable platform being encompassed on both sides by guide rails arranged on a machine frame.
