Definitions

  • the invention relates to a hammer, by means of which a drill bit furnished with a special bit holder is hammered on drilling a hole in soil or rock, a method to execute drilling with a large- diameter bit and a joint between the hammer and the holder.
  • the advantage of this invention is that the location and the way of fastening the support holder more toward the hammer outer circle from its conventional location and engagement allow a construction of quite another strength category.
  • the holder diameter can be substant ⁇ ially enlarged without any weakening cross grooves.
  • the holder becomes even shorter than the previous, for a corresponding bit diameter designed holders, since the holder expands immediately in the hammer front, for instance to the rate of the hammer outer diameter.
  • the supporting face of the holder is made larger than the hammer diameter, it is possible to install from the hammer outside oblong gliding and locking means on the sup ⁇ porting face itself, whereby the holder can be locked and opened even in the drill hole.
  • the solution according to this invention allows enlargement of the through hole in the holder center without weakening the holder strength.
  • the hole can be enlarged so that the scavenging air to the bit as well as the return air can be conveyed most suitably through the holder in using coaxial piping.
  • Fig. 1 - 3 show attachment principles of the support bushing.
  • Fig. 4 shows a previously known attachment of the support bushing to the hammer.
  • Fig. 5 shows a cross-section of the bit, the holder and holder attachment to the hammer.
  • Fig. 6 shows a cross-section of the holder and holder attachment to the extension of the hammer casing
  • Figures 1 - 3 illustrate different principles how the support bushing 3 can be attached to the hammer casing or formed from the hammer casing.
  • a threaded joint or a flange joint with screws can be used and the casing can be expanded or extended in order to form the bushing.
  • Percussion piston 2 can be in the casing.
  • FIG. 5 illustrates a support bushing 12 attached on the per ⁇ cussion machine casing 13 with a thread.
  • Percussion piston 14 is in the casing and glides also with regard to the holder by means of an intermediate bushing 17 that works as a packing.
  • the holder can move a limited distance in bushing 12. The distance is 50 mm, for instance, which is a sufficient travel between holder and bushing so that the holder does not hit the block stops in the bushing but the bit hits the soil it encounters.
  • gliding means In corresponding spots on bushing 12 inner face and holder outer face there are gliding means, axial grooves and ridges, so that rotation is transmitted from bushing to holder.
  • the holder has grooves 25, whereby there must be ridges in the bushing, which in the stage of installation glide into grooves 25 and by mutual rotation of bushing and holder, the ridges in the bushing are turned to the back of noses 26 that cut off the the grooves in the same manner as a bayonet joint From the out ⁇ side of the casing locking pins 27 are then pushed through holes in the bushing rear end into the joint itself, where the pins prevent the holder from turning so as to open the bayonet joint.
  • Pins 27 work also as gliding means for the mutual axial movement of holder and bushing.
  • Parts 18 are packings and, simultaneous ⁇ ly, gliding faces as well. In the bayonet joint necessary axial clearance is arranged, which must be done for the holder because of the travel of percussion.
  • the figure shows how coaxial channelings 15 and 19 and piping 16 are loosely arranged in the holder and also taken through the piston but not affecting the strength of the holder.
  • the tubular locking pin 27 illustrated in the figure can be secured by a side screw on its place. All locking pins can also be pulled out at a time by some arrangement and the joint open ⁇ ed, even with the equipment in the drill hole.
  • Figure 6 is another version of the holder support bushing 22 fastened on the casing by a threaded joint.
  • the bushing inner face has gliding grooves only and the holder 24 face has counter grooves.
  • a ring 21 has been left on the bushing 22 inner face working as a stopper.
  • Holder 24 can be pushed into bushing 22 and pulled out when so wanted.
  • locking ring 20 which is made of two parts, whereby on pulling holder 24 slightly to the left from the position in the figure, the locking ring halves can move outward into the groove in bushing 22. The holder can then move furhter to the left and out from the bushing, since the collar in the in the impact-receiving end can pass the halves of lock ⁇ ing ring 20.
  • the joint and the expansion of the holder according to this invention are especially well adaptable to drilling of large holes, for instance holes with a diameter over 300 mm, whereby the hammer follows the bit immediately and advances in the hole behind the bit.

Abstract

La présente invention concerne le forage d'un trou dans le sol ou de la roche au moyen d'un outil de forage mû par un marteau piqueur. Ce procédé et ce marteau piqueur mettent en ÷uvre le marteau piqueur de façon à forer, en l'occurrence, au moyen d'un burin minier de grand diamètre (23). Selon ce procédé, une pièce retenant la fixation du burin minier, par exemple une boîte guide (22), se fixe sur le carter du marteau piqueur. Le diamètre de la partie de retenue de la boîte est sensiblement plus grand que le diamètre de la face de contact de percussion de la fixation. En effet, ou bien les dimensions de la boîte guide sont telles que cette dernière peut se fixer facilement sur la surface externe du carter du marteau piqueur, ou bien la boîte guide constitue une extension du carter, mais avec des dimensions plus importantes.
