Definitions

  • the present invention relates to a propelling system in a small diameter pipe propeller for burying a small diameter pipe.
  • the conventional propelling system is provided with propelling jacks having a short stroke or provided with propelling jacks having a long stroke or telescopic cylinders.
  • the propelling system provided with the propelling jacks having the long stroke or the telescopic cylinders needs a space which is more than two times the stroke of the propelling jack or the telescopic cylinder in length, thereby causing such a problem that a large launching shaft should be excavated and the small diameter pipe can hardly be propelled from a space which is too narrow to excavate a large launching shaft therein.
  • the present invention is made to solve the drawbacks set forth above and is to provide a propelling system in a small diameter pipe propeller enabling small diameter pipes to be propelled efficiently in the small space.
  • the small diameter pipe propeller according to the present invention for propelling a small diameter pipe into the ground to bury it therein using a main body of the propelling system installed in a launching shaft, comprises propelling jacks and propelling rods provided in the direction of propelling the small diameter pipe, the forward ends of the propelling rods being movably supported by cylinders of the propelling jacks and the rear ends thereof being fixed to the forward ends of piston rods, a driving device for propelling the small diameter pipes reciprocally movably provided between the propelling rods, connecting means for selectively connecting the driving device with the propelling jacks or propelling rods interposed there between, and connecting means for selectively connecting the both ends of the propelling jacks and reaction receiving means interposed therebetween. Consequently, the small diameter pipe can be propelled into the ground by extending the driving jacks while the piston rods thereof are fixed, and also by contracting the driving jacks while the cylinders thereof are fixed.
  • FIG. 1 is a partly cut-away plan view
  • Fig. 2 is a side view
  • Figs. 3 to 4 are views showing an operation
  • Figs. 5 and 6 are views showing another embodiment.
  • a main body of the propelling system installed in a launching shaft 2.
  • Two reaction receiving rods 6 are placed on tables 3 so as to be in parallel with the propelling direction of a small diameter pipe 4.
  • Designated at 5 are a pair of propelling jacks slidably supported by the two reaction receiving rods 6 and the propelling jacks 5 comprise cylinders 5a and hollow piston rods 5b which protrude rearward from the cylinders 5a.
  • the propelling jacks 5 are supported by the reaction receiving rods 6 in the manner that the reaction receiving rods 6 penetrate the centers of both the hollow piston rods 5b and the cylinder 5a.
  • Oil pressure chucks 12 and 13 are provided at the front and rear ends of the propelling jacks 5.
  • the cylinders 5a and the piston rods 5b can be fixed to the reaction receiving rods 6 at arbitrary positions thereof by the oil pressure chucks 12 and 13.
  • a pair of propelling rods 14 are provided over and under the propelling jacks 5 so as to be parallel with the propelling jacks 5.
  • the forward ends of the propelling rods 14 are fixed to sliding plates 5c which are slidably engaged in the outer peripheries of the cylinders 5a and the rearward ends of the propelling rods 14 are fixed to brackets 5d which project from the oil pressure chucks 13 fixed to the tip end of the piston rod 5b wherein the sliding plates 5c can slide along the cylinders 5a accompanied by the extension and contraction of the piston rods 5b.
  • a driving device 7 is provided across the propelling rods 14.
  • the driving device 7 comprises a pipe propelling member 7a which is supported by the propelling rods 14 and the outer peripheries of the cylinders 5a of the propelling jacks 5 at the both end portions thereof and a driving unit 7b provided on the pipe propelling member 7a.
  • Pins 8 are detachably provided between the pipe propelling member 7a and the cylinders 5a while pins 9 are detachably provided between the pipe propelling member 7a and the sliding plates 5c, wherein the pipe propelling member 7a is selectively coupled to the cylinders 5a or the propelling rods 14 by the pins 8 or 9.
  • the driving unit 7b provided on the pipe propelling member 7a can rotatably drive a screw conveyer 15 (not shown) housed in the small diameter pipe 4 and a pilot head of a leading pipe (not shown) mounted at the tip end of the small diameter pipe 4.
  • the cylinders 5a of the propelling jacks 5 are advanced together with the driving device 7 as illustrated in Fig. 3 while the small diameter pipe 4 is propelled into the ground by the pipe propelling member 7a.
  • the pins 8 coupling the pipe propelling member 7a to the cylinders 5a are removed while the pins 9 are inserted into pin holes provided in the pipe propelling member 7a to thereby couple the pipe propelling 7a to the propelling rods 14.
  • both ends of the propelling jacks 5 may be respectively fixed to the upper surface of the table 3 by way of an insertable pins 16 so as to perform the same function set forth above instead of the reaction receiving rods 6 and the oil pressure chucks 12 and 13 as illustrated in Figs. 5 and 6.
  • the small diameter pipe can be propelled into the ground at both the times when the propelling jacks are extended and contracted so that the propelling time is reduced to half compared with the conventional arrangement where the small diameter pipe can be propelled into the ground at one of the times when the propelling jacks are extended and contracted, whereby a term of works can be remarkably reduced and a small diameter pipe can be propelled into the ground in a limited space so that the launching shaft can be small and provided economically.
