Definitions

  • the invention relates to a casing driver for thrusting/retracting of a steel pile or casing of a large diameter during the foundation work of building or civil engineering projects.
  • casing drivers There are two types of casing drivers: The oscillating type which oscillates a casing to thrust and retract it, and the rotary type which rotates the casing for the thrusting/retracting thereof.
  • the casing driver of the present invention is of a rotary type, as it is known, for example, from JP-A-61-270418.
  • the known casing driver has a chuck device provided on a rotational body to hold the casing with a split ring compressed by a hydraulic cylinder. While this rotational body is being rotated by a hydraulic motor, a thrust frame which rotatably supports the rotational body is lowered or raised to thrust or retract the casing.
  • This type as compared with the oscillating type, has high efficiency, can be driven into a harder layer of the ground, and allows a high degree of perpendicularity because of the unidirectional load applied to the casing.
  • the chuck device rotates together with the rotational body, thereby requiring frequent attachment/detachment of hydraulic hoses for supplying oil to the hydraulic cylinder. This has been an obstruction to efficient work.
  • a casing driver having a driven rotational body for rotating a casing, a thrust frame for rotatably supporting the rotational body, an elevating device for moving the thrust frame up and down for thrusting/retracting of the casing, and driving means for rotating said rotational body, and further comprising: a casing insertion hole formed in the rotational body and having a tapered surface convergent toward the casing; a support frame; a rotational frame so provided as to face the rotational body and rotatably supported on the support frame; a plurality of wedge-shaped chuck members hung through a linkage from the rotational frame and each having a tapered surface for sliding on the tapered surface of the casing insertion hole; and a chuck cylinder, provided on the thrust frame, for moving the support frame up and down.
  • a casing driver 1 In a casing driver 1, three thrust cylinders 5, serving as elevating devices to move a thrust frame 4 up and down, are mounted at equal intervals on a base frame 3 which is supported horizontally by four jacks 2.
  • a ring-shaped rotational body 6 is rotatably supported on the thrust frame 4 by a bearing 7.
  • a gear 8 formed which is engaged through an idler 10 with two hydraulic motors 9 mounted on the thrust frame 4.
  • An casing insertion hole 12 is formed in the inner wall of the rotational body 6, and six chuck flutes 14 each having a tapered surface 13 convergent toward the casing 11 are provided in the hole 12.
  • a rotational frame 15 is disposed above the rotational body 6.
  • the rotational frame 15 is supported rotatable through a bearing 20 on a support frame 19 disposed above the rotational frame 15.
  • the support frame 19 is supported elevatable on four chuck cylinders 21 mounted on the thrust frame 4.
  • Reference numeral 22 in Fig. 2 is a reaction counterbalancing lug.
  • casing driver 1 In the case where the casing driver 1 is mounted on an earth drill 23 to drive the casing 11, the thrust frame 4 is raised by the thrust cylinders 5 first. The casing 11 is lifted up and then lowered to be fitted in the casing insertion hole 12. When the support frame 19 is pulled down by actuating the chuck cylinders 21, the chuck members 17 are lowered together with the rotational frame 15. The chuck members 17, sliding down at their tapered surfaces 16 on the tapered surfaces 13 of the chuck flutes 14, are pushed in between the rotational body 6 and the casing 11 to chuck the casing 11.
  • the chuck cylinders 21 are actuated to lift up the chuck members 17 to thereby release the chucking of the casing 11, and the thrust cylinders 5 are actuated to lift up the thrust frame 4.
  • the chuck cylinders 21 are actuated again so that the chuck members 17 are forced in between the rotational body 6 and the casing 11 to chuck the casing 11, and the thrust frame 4 is lowered by one stroke length of the thrust cylinders 5 while rotating the casing 11. The above operation is repeated.
  • the thrust frame 4 In the case of retracting the casing 11, the thrust frame 4 is lifted up by means of the thrust cylinders 5 while rotating the casing 11 in chucked state.
  • the description of the above embodiment has been given with reference to the case where chuck flutes each having a tapered surface convergent downward are formed in the casing insertion hole of a rotational body and chuck members are pushed downward from above the rotational body, the chuck members may each have a tapered surface convergent upward and may be formed in the rotational body instead so that they can be pushed from under the rotational body.
  • the casing insertion hole may be formed to have its entire surface tapered.
  • a casing insertion hole having a tapered surface convergent toward the casing is formed in a rotational body that is rotatably supported on a thrust frame of a casing driver, and wedge-shaped chuck members, which slide on the tapered surfaces to be pushed between the rotational body, and casing to chuck the casing, are ascentably, or respectively descentably supported by chuck cylinders provided on the thrust frame. Therefore, the casing can be rotated in chucked manner without rotating the chuck cylinders.
  • this invention does not require the attachment/detachment of hoses for oil supply to, or discharge from, the chuck cylinders, thus ensuring a significant improvement in work efficiency.
