Definitions

  • the invention relates to an anchor drilling and setting device for drilling and setting anchors in the longitudinal center plane of a tunneling or mining machine in the roof, the tunneling or mining machine having at least one support near the face, which between The ridge and sole can be clamped and is articulated to the front end of the machine and to the rear area of the machine by means of links running in the longitudinal direction of the machine.
  • anchor drilling and setting devices When driving on routes, a certain anchor pattern must be observed to protect the rock protection.
  • anchor drilling and setting devices outside the outline of the plan view of a tunnel boring machine or cutting machine, and in particular when brittle slopes are to be feared, these anchorings should be made as close as possible to the working face in order to keep the undeveloped or unsecured area as short as possible.
  • Such anchor drilling and setting devices can be connected to the cutting machine or the tunnel boring machine in order to ensure the desired position near the face at predetermined distances from the face.
  • Such devices are described, for example, in AT-PS 392 119, in which the anchor drilling and setting devices are connected in an articulated manner to the cutting machine and can be hydraulically clamped between the roof and the bottom of the route.
  • a tunneling or extraction machine of the type mentioned at the outset, with which, however, only anchors can also be placed outside the longitudinal center plane, is described in GB-A 2 232 429.

  • the anchor drilling and setting device can also be pivoted into such a position so that a low-construction machine is achieved. which is easier to maneuver.
  • the design is such that the link running in the longitudinal direction of the machine has two arms which are essentially parallel to one another and that the anchor drilling and setting device is pivotably mounted on a support connecting the arms. Especially when using parallel arms to guide the front For reasons of vibration decoupling, it makes sense to articulate the two arms separately on the ridge cap, a space being created between such arms, in which the anchor drilling and setting device can be pivoted in a non-operating position.
  • the design is advantageously made such that the carrier has joints with the arms connected is.
  • the articulation of the carrier for the anchor drilling and setting device can be made in a structurally particularly simple manner so that the arms on their mutually facing inner sides parallel to the arms carry bolts or bearing eyes and that the carrier engages around the bolts bearing eyes or into the bearing eyes Has bolts, which at the same time also creates the possibility of moving the anchor drilling and setting device with the carrier in the manner of a slide in the longitudinal direction of the handlebars or the arms of the handlebars and positioning them accordingly.
  • the anchor drilling and setting device can thus also be brought closer to the working face.
  • the anchor drilling and setting device can be used in a substantially bank-right direction, ie with the formation of bores orthogonal to the longitudinal axis of the line, it being possible, of course, to use any pivot positions of the anchor drilling and setting device to achieve anchoring closer to the face.
  • a further decoupling and securing of the carrier against overloading with high vibrations can be achieved in that at least one bearing eye is designed as an elongated hole, the longer axis of which runs in the direction or parallel to the plane spanned by the arms. In this way, a compensation is created when the arms of the handlebar parallel to each other are elastically expanded, for example by high loads.
  • the design is such that the anchor drilling and setting devices are arranged on telescopically displaceable slides, one of which can be pivoted about the axis running transversely to the supports and can be fixed in its pivoting position is connected to a rotary actuator.
