Definitions

  • the invention relates to an anchor drilling and setting device for setting flexible anchors, in particular cable anchors, comprising a drill motor, a bearing for the drill motor, which acts on a feed drive for moving the storage together with the drill motor in the drilling direction, and a clamping device for the anchor.
  • a bolt-setting device for fastening bolts by means of a binding or cementing agent has been known in boreholes.
  • the bolts used in this case are flexible bolts, which are preferably pulled off a strand or a roll and cut to length with a cutting device.
  • the feeding device by means of which such a flexible bolt can be set, comprises traction rollers, wherein in the case described three driven tension rollers are provided, which naturally require a corresponding drive. After inserting the anchors they are cut off as soon as the anchor has reached the bottom of the drilled hole.
  • the displacement mechanism itself is rotatably mounted on an anchor drilling and setting device basic unit and is pivoted by means of a separate cylinder in the respective working position.
  • US 4,728,219 describes a self-propelled anchor drilling and setting device, in which cable anchors from a cable mel deducted and guided over a slide-in device, which is arranged on the frame of the chassis. Also in this device, the drive via friction rollers, which in turn require a separate drive.
  • the invention now aims to provide an anchor drilling and setting device of the type mentioned, in which without additional drive and without complex accessories flexible anchor, and in particular cable anchor can be set. It should be avoided constructive changes of the drilling motor and flexible anchor only by advancing, i. can be safely introduced into a borehole without rotation.
  • the anchor drilling and setting device is further developed to the effect that the drill motor with the clamping device for the armature is detachable, wherein the clamping device is held in the storage connected to the drill motor.
  • the clamping device fastened to a connecting rod can be removed from the common bearing or pivoted out of position in order not to hinder the drilling operation.
  • the clamp is placed in front of the drill drive and can be moved back and forth by the feed drive in the drilling direction.
  • the training is preferably made so that the clamping device has a bracket or hook for grasping the armature and preferably the clamping device at least one jaw , wherein the bracket or hook and / or the clamping jaw (s) are mounted to be movable transversely to the insertion direction.
  • bracket or hook or jaw This transverse mobility of bracket or hook or jaw relative to each other makes it possible to clamp the flexible armature or the cable when driving the drill motor in the direction of insertion, wherein such clamping can be done automatically, if the training, as it corresponds to a preferred development, so is made that the bearing has inclined slots at an acute angle to the insertion direction, so that upon a displacement of the clamp in the direction of insertion of the armature, the clamping force of the clamping device is increased.
  • the cable anchors cause a displacement of the interacting components bracket or hook or jaws relative to each other due to the inclined guide tracks in a movement in the direction of insertion, so that an automatic clamping occurs when inserting the cable anchor.
