Definitions

  • the invention relates to a horizontal earth drilling device.
  • Earth boring devices in particular horizontal drilling devices, are used to dig earth bores in the trenchless construction, for example for supply and disposal lines, or to replace old lines that have already been laid without trenches.
  • a drill pipe with drill pipe sections is usually used, in which the drill pipe sections can be connected to one another.
  • EP 0 886 034 B1 known to use a carriage movable back and forth in a frame for advancing and / or pulling a drill pipe.
  • the carriage has a receptacle for a drill pipe section, so that the drill pipe section in the direction of a feed axis. Creation of the earth hole in the recording can be moved.
  • the drive acting on the drill pipe section can have a rotary and / or translational effect on the drill pipe section in the receptacle.
  • the drive for moving the carriage in the frame can be made by means of a toothed rack, which is firmly connected to the frame, and a hydraulic motor, which is a toothed wheel which is mounted on the carriage can be moved. Furthermore, a cylinder package consisting of cylinders lying side by side can be used.
  • off DE 20 64 862 known to move a platform over hawser and a pulley or rollers.
  • the hawser is placed over a rotatable roller which is carried by a bracket at one end of the boom and is guided along the boom around another roller which is carried along by means of a bracket which is held on a piston of a double-acting hydraulic press piston of the boom.
  • a disadvantage of the device known from the prior art is that at low feeds, the full force development is not implemented, which is particularly the case with the cylinder packs comprising a plurality of cylinders lying next to one another. Furthermore, the high cost is disadvantageous. Use in an excavation pit is not optimal, since the construction is too large and / or the desired drill string length is not achieved.
  • SU 1 507 951 A1 and WO 2008/044996 A1 disclose other earth drilling devices.
  • the invention was therefore based on the object of specifying an improved horizontal earth drilling device which is improved compared to at least one of the aforementioned disadvantages.
  • the central idea of the invention is the combination of an element which can be extended relative to another element and the use of tension transmission means in the manner of a pulley, wherein deflection rollers for the tension transmission means of the pulley are arranged on the element which is the element from which the other element extends.
  • the drive for a back and forth movable carriage of an earth boring device for moving a drill pipe has a rod which can be moved in a frame relative to a cylinder and tension transmission means which act on the carriage.
  • the rod is connected to the frame and deflection rollers for the tension transmission means are present on the frame and on the cylinder.
  • the construction is simple and inexpensive, and a high degree of efficiency can be achieved even at very low speeds of the carriage movement.
  • Installation space is saved by attaching the deflection rollers for the train transmission means to the cylinder, which space can enable a compact construction of the drive.
  • An “earth drilling device” is understood in particular to mean any device which moves a drill pipe having drill pipe sections in an existing or to be created channel in the ground in order to create or expand a hole, in particular a horizontal hole (HD), or to conduct lines or other long bodies in to pull in the earth.
  • the earth boring device according to the invention is an HD device.
  • An “earth drilling device” comprises a device that drives a drill pipe, which works to displace soil, and which introduces the drill pipe into the soil in a rotationally and / or translatory manner in the longitudinal axial direction of the drill pipe.
  • HD horizontal drilling, horizontal drilling
  • earth channels including earth drilling, rock drilling or underground pipes as well as underground or above-ground pipelines and water channels can be manufactured or pulled in using an appropriate earth drilling device.
  • the term “carriage” encompasses a body with a receptacle for a drill pipe section, the drill pipe section being able to be driven in a translatory and / or rotating manner by means of the receptacle.
  • the slide can be guided in the frame for a translatory movement along a path.
  • the slide rests on a support connected to the frame with support elements.
  • the support can be profiled and the support elements can be designed as rollers. Runners are also possible as riot elements.
  • the carriage can be guided hanging and / or resting on the frame.
  • the carriage can thus be a machine element that can be moved along a path, in particular in a purely translatory manner, in the frame.
  • the term “frame” encompasses a box-shaped or cuboid structure, the side walls and / or struts or rods of pressure, tension and can also transfer bends.
  • the frame according to the invention preferably has a quadrilateral elevation and can be arranged in a pit to create the earth hole.
  • the drive unit and slide are preferably arranged in the frame.
  • the frame can be provided with horizontally extendable clamping supports, via which the recoil forces can be introduced into the ground.
  • the cylinder is a hydraulic cylinder and the rod is a piston rod on the hydraulic cylinder, so that an inexpensive hydraulic cylinder can be used.
  • a hydraulic cylinder can be used well under the harsh conditions encountered in earth drilling. Hydraulic fluid and pumps required for operation are inexpensive to use.
  • the tension transmission means in short tension means, is a rope or a chain, as a result of which simple, stable tension transmission means, which can be selected according to the respective requirements, can be used.
  • One end of the train transmission means is preferably fastened to the frame, as a result of which a connection to a particularly stable component contributes to the stability of the drive.
  • the invention provides a horizontal earth drilling device with a slide arranged in a frame for advancing a drill pipe and a rod which can be extended relative to a cylinder, tension transmission means for moving the slide being fastened to the slide.
  • the rod is connected to the frame and the tension transmission means are guided over deflection rollers mounted on the frame and on the cylinder.
  • the deflection rollers mounted on the cylinder can be fixedly arranged on the cylinder with their axis of rotation.
  • a double-acting standard cylinder can be used because the drive can be aligned or oriented in such a way that lower forces are required for the feed in the direction of the borehole (piston ring space as effective area) than for retraction (entire piston area as effective area).
  • Such a cylinder is referred to as a "differential cylinder", which has only one piston rod and thus a piston surface and a smaller piston ring surface. As a result, higher forces can be made available for the power input. While in a so-called “synchronous cylinder" the pressurized surfaces are generally the same size for both strokes and thus the forces generated are also the same size, this is different for a differential cylinder in the manner described above.
  • tension transmission means can be guided past one another.
  • the rollers arranged on the cylinder have a smaller diameter than the deflection rollers mounted on the frame, in particular a ratio of the diameters of 1: 1.3 to 1: 1.7, very particularly preferably 1: 1.5, can be selected.
  • Fig. 1 shows a horizontal earth drilling device for performing an earth drilling.
  • the earth boring device has a carriage 5 which can be moved back and forth in a frame 6 and which rests on a support.
  • the support is designed and profiled as a guide for support elements of the slide 5.
  • the cylinder 2 is a double-acting cylinder with which work can be done in both directions.
  • the rod 7 is attached to the end of the frame 6.
  • the drive further comprises train transmission means 1 in the form of ropes.
  • train transmission means 1 in the form of ropes.
  • Two pull transmission means 1 act on the slide in each of the two directions of movement of the slide 5.
  • Each tension transmission means 1 is guided over a deflection roller 3 on the frame 6 and over a deflection roller 4 attached to the cylinder 2.
  • the other end of the train transmission means 1 is firmly connected to the frame 6.
  • Four train transmission means 1 are provided, two on each side of the carriage 5.
  • the Fig. 1 it can be seen that two deflection rollers 4 are arranged laterally on the cylinder 2.
  • the pairs of deflection rollers 4 lie opposite one another.
  • the two deflection rollers 4 on one side are arranged side by side.
  • the axes of rotation of the two deflection rollers 4 run parallel to one another offset.
  • the deflection rollers 3 and the deflection rollers 4 on one side are arranged essentially in one plane.
  • the axes of the deflection rollers 3, 4 on one side run essentially parallel to one another and the deflection rollers 3, 4 are arranged essentially at the same height as it is Fig. 1 shows.
  • the articulation or engagement points of the train transmission means 1 on the frame 6 and on the carriage 5 of one side are in one plane with the deflection rollers 3, 4 of the corresponding side, as is the case Fig. 1 shows.
  • Fig. 2 is the top view in Fig. 1 Earth boring device shown without guide rollers 4 and slide 5 shown.
