Definitions

  • the invention relates to a fastening and tensioning device for a ram boring machine connecting a pipe to be pulled in with the ram boring machine Pull rope.
  • Such fastening and tensioning devices are required to insert one into an earth hole Pipe from a ram boring machine that drills the earth to be retightened if the pipe is not tensile can be connected to the ram boring machine.
  • a known fastening and tensioning device of this type is one end of the pull rope in one with the ram boring machine attached and tensile connected sleeve through a pull tube inserted into the sleeve.
  • On the free end of the draw tube is a Pressure piece with an axially displaceable clamping device put on for the rope.
  • the clamping device consists of clamping jaws that can be clamped with screws, which are axially displaceable in a guide.
  • At this Leadership engages one connected to the jaws Clamping screw, by means of which the clamping jaws axially shift.
  • the invention is based on the problem, a simple one fastening and tensioning device to be handled create, the clamping stroke is unlimited and at any time allows easy re-tensioning.
  • the invention consists in a Fastening and tensioning device of the aforementioned Kind with an adjacent to the pressure piece, at one acting in the direction of the pipe to be drawn in Force on the pulling rope clamping element and with one arranged coaxially to the clamping element, at one clamping in the direction of the pipe to be drawn in, opposite towards the direction of the pipe to be drawn in Force movable clamping element to be provided.
  • the clamping element and the tensioning element act automatically jamming when one towards the retractable Rohrs acting force on the pull rope occurs during the clamping element and the tensioning element the pull rope release when a movement in opposite Direction takes place.
  • the pull rope by means of the tensioning element through a To tension forward and backward movement, the Clamping element the pull rope with every forward movement holds the clamping element and the clamping element thus grab a piece of rope and move backwards can tighten again.
  • the clamping element can be parallel, on parallel core have guided jaws, and the parallel link can be articulated on an extension of the pressure piece be.
  • a simple release of the clamped between the jaws Pull rope can be attached to one by one Reach parallel extension arranged lever extension.
  • the clamping element In order to ensure an automatic pinching under all circumstances to reach the pull rope, the clamping element be loaded with a spring in the clamping direction.
  • the tensioning element can be constructed similarly and also have parallel jaws guided on a parallel core.
  • the parallel links are on another pair of links articulated on the one hand on the extension of the pressure piece and on the other hand by a another handlebar is connected to each other and one Has handle for tensioning the pull tube.
  • This Handle can be from a lever extension on the pair of handlebars connecting links exist.
  • the jaws and thus that which is clamped by the jaws Move the pull rope in the tensioning direction, whereby the jaws of the clamping element during the pull rope release this movement.
  • the tensioning element moved opposite to the tensioning direction keep the Clamping jaws of the clamping element, the pull rope firmly while the clamping jaws of the clamping element on the Rope can move to a new piece of rope to clamp further spans.
  • That Pressure piece has a side opening for inserting the Draw rope, while the jaws on one side led to the parallel core and thus by accessible on the same side as the side Opening on the pressure piece.
  • a sleeve For attach the pull rope to the ram and for receiving one end of the pipe to be drawn in a sleeve may be arranged at the end of the ram boring machine.
  • the sleeve or the ram boring machine have a circumferential one Rope groove with one leading into the inside of the sleeve Opening up.
  • the pull rope can then be through pipe to be drawn in and the sleeve, through the opening through and into the rope groove and back again through the opening into the inside of the sleeve.
  • the free end of the rope is firmly connected to the cable.
  • To parallel rope areas between the opening and the tensile connection can be one in the groove lying rope loop exciting spring can be arranged.
  • a sleeve 2 arranged, into which a pipe 3 to be inserted is inserted is.
  • a Towing rope 4 performed with the ram boring machine 1 and the sleeve 2 is connected and by means of a Fastening and tensioning device can be tensioned.
  • a pressure piece 5 is arranged, which from a the pipe end of the pressure plate 6 and one in the pipe end 7 inserted pipe socket.
  • the Pressure plate 6 and the pipe socket 7 are with a side slot 8 provided to the pull rope 4th conveniently in the area of a clamping element 10 and one Bring clamping element 15.
  • the clamping element 10 is in the vicinity of the pressure plate 6 arranged on an extension 9 and consists of parallel Clamping jaws 11, which are connected by means of parallel core 12 are articulated on the extension 9.
  • the bigger the on the pull rope 4 acting force the stronger the Clamping by means of the clamping jaws 11.
  • a lever extension 13 is arranged, the by means of a spring 14 in the direction of the pressure plate 6 is pulled.
  • the clamping element 15 has also parallel jaws 16, which are coaxial the jaws 11 and the pipe 3 to be drawn in are.
  • the jaws 16 are on parallel core 17 arranged, but not directly on the extension 9, but are articulated on a pair of links 18, by a further link 19 to a link parallelogram is added.
  • On the other handlebar 19 is a lever extension 20 is arranged with which the Pull rope 4 can be tensioned. For this the pull rope 4 between the jaws 11 of the clamping element 10 and the jaws 16 of the clamping element 15 are placed.
  • the clamping element 15 By moving the lever extension 20 in the opposite direction the rope becomes the pressure plate 6 by the clamping element 10, the pressure piece 5 and the pipe 3 to be drawn and excited.
  • the clamping element 15 is now in Moves towards the pressure plate 6, holds the clamping element 10 the pull rope 4 firmly, and the pull rope 4 can be moved by moving the Clamping element 15 opposite to the direction of Tension pressure plate 6 further.
  • the clamping element 15 can be any desired bias of the pull rope 4. It is the same possible to pre-tension the pull rope 4, if this during the advance of the ram boring machine 1 has subsided to increase again.
  • the clamping element is sufficient to release the pretension 10 opposite by moving the lever extension 13 to move towards the pressure plate 6 while doing so the jaws 16 of the clamping element 15 open hold.
  • a simple and secure connection of the pull rope 4 with the ram boring machine 1 or the sleeve 2 can reach when the ram boring machine 1 or the sleeve 2 are provided with a circumferential rope groove 21 which connected to the inside of the sleeve 2 via an opening 22 is.
  • the pull rope with the Ram drill 1 and the sleeve 2 can also be a piece of rope act, the ends of which by means of the tensile connection 23 are connected.
  • the pull rope 4 can then be attached to the tensile connection 23.
