Definitions

  • the invention relates to a tunneling or mining machine comprising cutting tools which can be moved over the face and which are arranged on a cantilever arm, and a platform which can be moved in the longitudinal direction of the machine and which carries route support equipment.
  • Such a driving or mining machine is from AT 507495 A1 known.
  • an anchor drilling and setting device arranged on a sliding track is known in which an additional manipulator for lifting and assembling warping mats is attached to a rollover of the anchor drilling and setting device.
  • One embodiment of a dismantling device with two anchor drilling and setting devices, which are pivotably supported on an anchor platform that can be displaced in the longitudinal direction of the machine, is the subject matter of FIG AT 413230 B .
  • the DE 29 34 625 A1 shows a combination of a tunneling machine with expansion devices, in which a expansion manipulator is fixed on a shifting track so that pre-assembled route arcs can be transported along the tunneling machine and positioned in the front area of the tunneling machine in the route.
  • Another example of an expansion manipulator that can be moved on a sliding track can be the DE 29 08 452 A1 can be removed.
  • the described embodiments thus relate on the one hand to the provision of individual route expansion devices in connection with a tunneling machine, whereby a certain work step within the scope of the route expansion can be mechanized and efficiently designed, but manual work steps are still required are.
  • the described embodiments relate to multifunctional solutions (e.g. AT 507495 A1 ), which can be used in a variety of ways, but for which adaptation measures are required in individual cases that make mechanized work more difficult.
  • the aim of the invention is therefore to develop a tunneling machine with integrated route expansion devices in such a way that the degree of mechanization for a combined route expansion can be significantly increased.
  • the individual expansion devices should be able to be placed on the heading machine in such a way that the lowest possible overall height is achieved.
  • the track expansion devices comprise an expansion manipulator and an anchor drilling and setting device, the anchor drilling and setting device being attached to the movable platform so as to be pivotable between a parking position and an operating position and the expansion manipulator being a telescopic one and has an arm which is pivotable in the vertical direction and which is attached to the movable platform and which carries a gripping device for temporarily receiving at least one extension element, in particular an extension arch, the extension manipulator and the anchor drilling and setting device being attached to the movable platform at a predetermined, fixed distance from one another and can be moved together with the movable platform between a retracted and a forward position.
  • the anchor drilling and setting device is pivotably arranged on the platform between a parking position and an operating position, the anchor drilling and setting device can be stored in a space-saving manner during the drive without hindering the cutting process.
  • the anchor drilling and setting device In the parking position, the anchor drilling and setting device is preferably in a state folded flat onto the movable platform.
  • the expansion manipulator has a telescopic arm that is attached to the movable platform so that it can pivot in the vertical direction, the expansion manipulator can also be pivoted down onto the movable platform for driving the road in order to minimize space consumption.
  • the telescopic arm of the extension manipulator which can be pivoted in the vertical direction, has a gripping device with which the individual segments or already screwed multiple segments of the extension elements, in particular extension arches, are picked up and brought into the installation position. Due to the pivotable and telescopic construction of the arm, precise positioning of the gripping device together with the support element temporarily held in the gripping device, in particular the support arch, is made possible. After the gripping device has brought the at least one extension element to the intended position, the extension element is usually assembled from bottom to top, the stamps being placed first and the extension arch connected to the previous extension arch via spacer bars.
  • expansion manipulator and the anchor drilling and setting device are attached to the movable platform at a predetermined fixed distance from one another eliminates the need to adjust the mutual position of the two expansion devices, so that handling can be simplified and mechanization improved.
  • the operating position of the anchor drilling and setting device relative to the expansion manipulator is selected in particular so that anchors can be set in the area of the vertical plane defined by the expansion element positioned by the gripping device.
  • the route expansion devices further comprise a lifting crane which has a telescopic boom that can be rotated about a horizontal axis of rotation.
  • the lifting crane is preferably fastened to the movable platform at a predetermined fixed distance from the expansion manipulator or from the support device.
  • the movable platform thus carries all of the essential route expansion devices required for the route expansion, namely the lifting crane, the expansion manipulator or the support device and the anchor drilling and setting device.
  • the track extension is preferably carried out in such a way that the lifting crane first grabs at least one track extension element in the retracted position of the platform, picks it up, transports it forward by pivoting the crane boom and places it in a holding device of the gripping device of the extension manipulator. The movable platform is then moved forward and the at least one extension element is pressed against the roof by means of the telescopic arm of the extension manipulator.
  • the gripping device comprises at least one, preferably two, receiving pockets for one extension element, in particular one extension arch.
  • two extension elements in particular extension arches, can thus be brought into the installation positions at the same time, so that the speed of the line extension increases can be.
  • the distance between the two receiving pockets simultaneously determines the desired distance between two successive expansion elements.
  • the gripping device comprises a particularly bow-like support device for temporarily holding a warping mat
  • a warping mat can be positioned at the same time as the gripping device or the extension elements are pressed against the roof, so that immediately afterwards already with the setting the anchor can be started.
  • the platform is supported in the forward-shifted position on a support arranged on the extension arm.
  • pivoting of the anchor drilling and setting device between the parking and the operating position as well as the degree of freedom required for setting anchors in the entire route profile are particularly easily achieved structurally in that a pivoting device for pivoting the anchor drilling and setting device between the parking position and the operating position is provided, at which a rollover is arranged, by means of which the anchor drilling and setting device can be pivoted in the operating position about an axis of rotation extending in the longitudinal direction of the machine. It is particularly advantageous here if the pivoting device is arranged at the front end of the movable platform. This makes it possible to move the rollover or the anchor drilling and setting device down into the operating position beyond the front end of the movable platform to pivot, so that the most central possible positioning of the anchor drilling and setting device within the route profile is achieved.
  • the design is preferably developed in such a way that the pivoting device has at least one support punch that can be extended against the base in the operating position of the anchor drilling and setting device.
  • working platforms are arranged on the movable platform on both sides of the machine longitudinal center plane.
  • the work platforms can each be lowered and raised relative to the movable platform by means of a lowering and lifting device.
