Definitions

  • the invention relates to a tensioning chain for transmitting driving forces to a jacking pipe.
  • Devices for transferring drive forces to pipelines are used when laying underground lines.
  • a target pit or on the ground surface of the drill head is then replaced at the front end of the drill string by an expander, which is then pulled by means of the linkage together with a pipe string through the pilot hole.
  • considerable forces are required due to the necessary soil displacement with the help of the expansion head at the front end of the boom.
  • German Offenlegungsschrift 10 2009 054 183 discloses a pulling and pushing device in which a lifting carriage with a tensioning element is movably arranged on a frame.
  • the tensioning element serves to grasp the pipe string and to move forward a piece corresponding to the carriage stroke in one or the other direction.
  • the clamping element has a coupling tube surrounding the product tube with a pressure medium hose which is arranged between spirally extending inner ribs of the coupling tube.
  • German Patent 10 2006 062 322 a device for pressing tubes is known in which a carriage is movable on guide rails.
  • the carriage has at its ends a crosshead, each with an injection ring, with the aid of which the pressing force is transmitted to a pipe to be pressed into the ground.
  • This press ring consists essentially of two opposite half shells for positive engagement of the tubing.
  • the half-shells are connected to each other by bolted against their end faces retaining rings that the positive connection is maintained even during the transmission of high forces.
  • a disadvantage of the known devices for transmitting drive forces to pipes or pipe strands is their high structural complexity and beyond their limitation to a relatively small range of different pipe diameters. In a diameter change, therefore, a considerable installation and time is required.
  • the invention is based on the problem to provide a device that allows a quick adjustment to different pipe diameters and the transmission of different high propulsive forces with low structural complexity.
  • the solution to this problem consists in a tensioning chain of individual shell-shaped, in each case, for example, via a joint pivotally interconnected ring pieces, which can be easily around alone or to several adjacent to a jacking pipe.
  • the ends of the tensioning chain then only need to be connected to each other.
  • two of the ring pieces can be connected to each other via a clamping cylinder, which is connected for example via L-shaped tabs with the respective adjacent ring piece.
  • the ring pieces can be provided on their the tube surface facing side with adhesive pad, for example, in the manner of a brake pad.
  • the tensioning chains are in a two-piece chain case connected to double acting hydraulic push and pull cylinders for applying the propulsion or pulling force.
  • the push and pull cylinders can be mounted in a bogie, which allows the lateral deflection of the drive during pipe jacking.
  • the bogie is preferably equipped with arcuate head ends between complementary guide pieces.
  • FIG. 1 shows a perspective view of an open tensioning chain
  • FIG. 2 shows the tensioning chain according to FIG. 1 when closing the ring
  • FIG. 3 shows the tensioning chain in the closed state
  • FIG. 6 shows a two-part tensioning chain housing with a jacking pipe before assembly
  • FIG. 7 shows the tensioning chain housing of FIG. 6 in the assembled state
  • Fig. 8 is a pulling and pushing device with the chain case
  • Fig. 9 is a plan view of the clamping device with a pivotable cylinder housing.
  • the tensioning chain 1 consists of several interconnected via a joint 2 ring pieces 3, the number of which is such that the chain closely surrounds a jacking pipe 4, as shown in FIGS. 4 and 5.
  • the individual ring pieces 3 are slightly curved, at least on their inside, so that, in the operating state, they rest closely against the pipe surface (FIGS. 4, 5).
  • the ring pieces 3 are provided on their inner surfaces with a pad-like, an increased frictional resistance coating 5, for example, a conventional brake pad.
  • the individual ring pieces 3 have - with two exceptions (Fig. 2) - the same dimensions. These exceptions are the ring piece 6, with double length and the ring piece covering 7 on a curved support plate, which are provided with L-shaped tabs 8, 9 and 10 respectively and receive a hydraulic clamping cylinder 11 between them.
  • the clamping cylinder 1 1 is on the one hand articulated with the tab 10 and its piston rod 12 is connected to the other articulated with the two L-shaped tabs 8, 9.
  • the clamping cylinder 1 1 thus allows a tensioning and loosening of the annular closed clamping chain 1 in the installed state (Fig. 4).
  • a plurality of ring pieces as shown in Fig. 5 in the tensioned state with extended piston rod 12 close together and record a very wide range of propulsive forces.
  • a housing 15 consisting of a cap-like upper part 13 and a complementary lower part 14 surrounds the annular piece package 16 (FIG. 6, FIG.
  • a U-shaped bracket 17 with two hand wheels 18, 19 is used to hire each paired rollers 20, 21 as a guide for the jacking pipe 4.
  • the lower part 14 of the ring piece housing 15 has a pocket 22 for the ring piece package 16, the width of which depending on the number of tension rings can be reduced by fitting pieces, not shown.
  • the housing 15 serves primarily to transmit power, for example, four pairs of thrust and pull cylinders 23 arranged in pairs on the sides of the propulsion tube 4. These thrust and tension cylinders are each mounted in a bearing piece 24, which in turn is mounted in the side cheeks 26 of the machine bed 27 by means of pins 25 is.
  • the piston rods 28 of the push and pull cylinders 23 engage in pairs hinged to a respective bearing block 29 on each side of the upper housing part 13.
  • the exposed as shown in Fig. 8 and immovably connected to the machine bed 27 push and pull cylinder 23 may be stored in Fig. 9 in a swing frame 30 to a non-linear course of the earth hole or the propulsion tube 4 located therein to be able to avoid something laterally.
  • the push and pull cylinders 23 are housed in chambers 31, 32 of the swing frame 30, the end faces 33, 34 extend arcuately and are guided in complementary bearing pieces 35, 36. These bearing pieces are immovable to support bodies 37, 38 at.
