Definitions

  • This invention relates to devices for insertion of rotating tools into the ground. Such tools are normally mounted at the end of a tube.
  • the word "tube” will be used hereinafter for indicating any elongate drilling means which may be caused to penetrate into the ground.
  • the jaw grip also controlled by three jacks may occur any time at a different position, not exactly coincident with the axis of the device controlling the tool advancement and rotation. This could cause the distortion of the tool carrier tube and inaccuracies in hole execution.
  • This device of the prior art allows only the use of drilling devices for which the rotation can be discontinuously imparted; for example, use cannot be made of tricones, diamonded tools for the drilling of rocks or alluvial grounds, etc.
  • GB-A-1,094,201 discloses an apparatus for inserting and rotating tools penetrating into the ground, said apparatus having a hollow implement for selectively gripping and rotating a tool carrier tube which penetrates into said hollow implement.
  • said implement comprises an actuating head for maintaining said tool carrier tube in rotation by a motor and a suitable kinematic chain driving a rotating hollow means.
  • the inventive apparatus comprises an actuating head 1 mounted on a column 3 carried by a structure 4 movable on tracks, wheels or sliding blocks 5.
  • Said actuating head 1 is vertically driven along the column 3 by known means provided on the column, which applies axial forces relative to tube T and directed in both directions that is forces serving both to drive the tube T into the ground and withdraw it.
  • the actuating head 1 performs the function of causing the hollow central shaft 15 and sleeve 16 integral therewith to rotate by means of two hydraulic motors 23 (Fig. 4).
  • the vice 2 is provided integral with the sleeve 16. Its function is that of selectively gripping and disengaging the tube T. Both said head 1 and vice 2 are hollow, so as to allow the passage therethrough of said tube T which projects below and above thereto. After the tube has been gripped, said head 1 and vice 2 moved downward. When the positions 1a and 2a, shown by broken lines in Fig. 1, are reached respectively by vice and head, said vice releases the tube T and moves upward along the tube to grip it again at the position shown by full line.
  • each hydraulic motor 23 can be connected to both the pinion 41 and gear 42 by means of the clutch 49.
  • Said pinion 41 and gear 42 respectively mesh with the gear wheels 43 and 44 integral with the shaft 45, on which the pinion 46 is also mounted. The latter drives the wheel 47 integral with the hollow shaft 15.
  • Said hollow shaft 15 is slidably connected to a sleeve 16 which is integral for rotation with the shaft 15, but axially free.
  • the sleeve 16 has an integral flange 16a, to which the flange 37a of said vice 2 is bolted (Figs. 2 and 3).
  • the vice 2 has a ring 37 coaxial with the hollow shaft 15.
  • Said ring 37 has a flange 37a which is made integral with the flange 16a.
  • Said ring 37 is provided with ears 37b, each of which having a rod 48 pivoted thereto by a pin 48a.
  • the movable jaws 33 are secured by screws 36 to the end of rods 48, so that such jaws are pendulum mounted. Thus, they can be readily replaced by other jaws of different sizes, such as to accommodate tubes T of different diameters.
  • each jaw 33 has a sloping surface 33a cooperating with the sloping surface 27a of a plate 27 mounted on a collar 26 providing for radially displacing said jaw 33 whenever said collar is axially moved.
  • Said jaw 33 is held at opening position by springs 30.
  • the axial movement carried out by the collar 26 is imparted to the latter by a hollow jack 50 which does not rotate.
  • the jack 50 is supported by the ring 37 through the two thrust bearings 21 and bushing 28 and is arranged concentrically to the ring 37 and sleeve 16. It consists of a hollow piston 29 and jacket 38.
  • the piston 29 is axially secured to the ring 37 by screws 29a and flat bushing 39 penetrating into a notch 39a integral with said piston 29.
  • the jacket 38 is axially movable together with the collar 26 which does not rotate. This is provided with a notch 26a, in which the flat bushing 59 slides.
  • Bushing 59 is integral with said jacket 38 by the screw 24.

Claims (4)

1. Appareillage pour introduire un outil de perforation dans le terrain et le faire tourner de façon continue, qui prévoit un instrument creux pouvant sélectivement saisir et faire tourner un tube (T) porte-outil qui pénètre dans ledit instrument creux, qui comprend:
a) une tête d'actionnement (1) pouvant maintenir en rotation ledit tube (T) porte-outil à l'aide d'un moteur (23) et une chaîne cinématique opportune (41-47) qui actionne un moyen creux rotatif (15, 16);
b) un moyen de prise (2) qui entoure et soutient le tube porte-outil (T), moyen qui est actionné hydrauliquement de sorte que ledit tube (T) puisse être actionné en appliquant à ce dernier un couple et une force axiale dans n'importe quelle direction,
caractérisé en ce que le moyen de prise est formé par un étau (2) solidaire dudit moyen creux rotatif (15, 16), ledit étau étant actionné par un vérin (50) creux, non rotatif, disposé concentriquement par rapport audit moyen creux rotatif (15, 16) et ayant un piston creux (29) axialement fixe, tandis que sa chemise (38) est axialement mobile et qu'elle commande le déplacement radial des mâchoires (33) de prise du tube en déplaçant axialement un collier non rotatif (26) ayant une plaque (27) avec une surface inclinée (27a) qui collabore avec une surface inclinée (33a) des mâchoires de prise (33) montée à pendule sur l'étau (2).
2. Appareillage selon la revendication 1, caractérisé en ce que lesdites mâchoires (33) sont montées à pendule avec un pivot de suspension (48a) solidaire du moyen creux rotatif (15, 16).
