Definitions

  • the present invention relates to a rotary-percussive hydraulic hammer drill according to the preamble of claim 1.
  • a hammer drill is known from EP-A-0 058 650 and is more particularly used on a drilling rig.
  • a drilling rig includes a roto-percussion hydraulic rotary hammer sliding on a slide and driving one or more drill bars, the last of these bars carrying a tool called cutting which is rock contact.
  • a hammer perforator generally aims to drill more or less deep holes in order to place explosive charges.
  • the hammer drill is thus the main element which, on the one hand, confers on the cutter the rotation and the percussion by means of the drill bars so as to penetrate the rock, and on the other hand, provides an injection fluid so as to extract debris from the drilled hole.
  • a hammer drill comprises a mechanism, driven by one or more hydraulic fluid flows from a main power supply circuit of the striking mechanism, acting on the drill bars through a fitting which is adapted to retransmit, on the one hand, the successive shocks caused by a striking piston, and on the other hand, the rotation due to a hydraulic rotary motor.
  • the support force of the hammer drill on the drill bars, and thus by transmission of the cutter on the rock, is obtained using the hydraulic motor of the slide. More specifically, the bearing force is transmitted from the body of the hammer drill to the fitting via a stop element incorporated in the hammer drill.
  • This abutment element may consist of a fixed piece of rotary friction, but more generally, for powerful hammer drills, a stop piston whose surface is hydraulically supplied so as to ensure a transmission of the force of support by means of a fluid.
  • European Patent Applications EP 0 058 650 and EP 0 856 637 disclose thrust piston arrangements for which the hydraulic supply comes from the main feed circuit of the striking mechanism. But when the operator closes this main supply circuit and activates for example only the rotary motor, the surface of the stop piston is no longer fed hydraulically and the piston can therefore come into direct contact with the body of the hammer. perforator, which can lead to considerable damage.
  • the hammer drill according to the present invention aims to solve the problem mentioned above and for this comprises a body enclosing a reciprocating plunger piston sliding under the effect of a main hydraulic supply circuit, this main circuit being also intended to cause the sliding of a substantially annular abutment piston housed in a cavity of the body and having, on the one hand, a front face for positioning a fitting at a predetermined distance from the striking piston, and secondly, a rear face located opposite a rear wall of the cavity, characterized in that an external hydraulic supply circuit is suitable, during the shutdown of the main supply circuit, to introduce a fluid under pressure between the rear face of the stop piston and the rear wall of the cavity so as to maintain a space therebetween.
  • the external supply circuit opens into the rear wall of the cavity and a sliding annular liner is placed around the rear portion of the stop piston and is able, on the one hand, to prevent the introduction of the fluid delivered by the external supply circuit when the pressure in the annular rear chamber is greater than or equal to a determined value (P), and secondly, allow the introduction of this fluid when the pressure in the annular rear chamber is less than the determined value (P).
  • the stop piston has a front portion, a central shoulder and a rear portion, said central shoulder being flanked by an annular front chamber and an annular rear chamber, and the main supply circuit is intended to deliver a fluid directly.
  • a connecting channel is intended to put the rear chamber in free communication with the front chamber.
  • the rear face of the stop piston is put under the pressure of a drain by means of a first channel.
  • the front chamber is also placed in communication with the drain by means of a second channel when the fitting is at a distance from the striking piston less than the predetermined distance.
  • the stop piston is intended to slide inside a guide integral with the body.
  • the liner has a rear portion having, on the one hand, an outer shoulder having a first rear surface intended to cooperate with the external supply circuit, and on the other hand, an internal recess having a second rear surface offset.
  • a substantially annular chamber connected to the main circuit is provided between the outer shoulder of the liner and a rear end of the guide.
  • the front face of the stop piston advantageously has a diameter substantially greater than that of the rear face.
  • a hammer drill 1 has a body 2 comprising a cavity 3 which extends towards the rear in a bore 31 containing a striking piston 4. More specifically, the cavity 3 encloses a substantially annular stop piston 5 which can slide around the striking piston 4, an annular sleeve 6, a fitting 7 and a rotary motor 8. The fitting 7 is connected to drill bars 9 which act on a cutting edge 10 in contact with the rock 11.
  • the stop piston 5 has a front portion, a central shoulder 12 and a rear portion, the central shoulder having a front annular surface 25 and a rear annular surface 26.
  • the piston abutment is provided respectively with a front face 13 and a rear face 14. More particularly, the front face 13 is in contact with the fitting 7 and the rear face 14 is opposite a rear wall 15 of the cavity 3.
  • the liner 6 is placed around the rear portion of the stop piston 5 and is slidably sealable therealong.
  • the front portion of the stop piston 5, the front surface 25 of the central shoulder 12 and the body 2 define a front chamber 16 annular.
  • the rear portion of the stop piston 5, the rear surface 26 of the central shoulder 12, the body 2 and the liner 6 define an annular rear chamber 17.
  • a connecting channel 18 is provided so that, in operation, put the front chamber 16 and the rear chamber 17 at the same pressure.
  • a first channel 30 longitudinally traversing the stop piston 5 over its entire rear portion makes it possible to put the rear face 14 of the stop piston 5 at the pressure of a drain 19 via a groove 20.
  • a second channel 21 formed in the front portion of the stop piston allows the communication of the front chamber 16 with the groove 20 and the drain 19.
  • a main hydraulic supply circuit 22 for the hammer drill 1 is connected to the bore 31 containing the striking piston 4, but also to the rear chamber 17.
  • an external hydraulic supply circuit 23 independent of the main circuit 22 has an end opening into the rear end 15 of the cavity 3 at the level of the jacket 6.
  • the hydraulic motor of the slide (not shown) containing the hammer drill 1 applies a bearing force on the body 2, as illustrated by the arrow 24.
  • This bearing force is transmitted to the stop piston 5 by means of of the main circuit 22, which generates a fluid under pressure in the rear chamber 17 so as to exert stresses on the rear surface 26 of the shoulder 12 and on the liner 6.
  • the stop piston 5 is then caused to slide forward and transmits the support force by its front face 13 to the fitting 7, and thus to the drill bars 9 and the cutter 10.
  • the sleeve 6 is pushed backwards and closes the external circuit 15.
  • the piston stop 5 stops its stroke because a pressure balance is established between the front chamber 16 and the rear chamber 17 so that the fitting 7 is then placed at a predetermined adequate distance from the striking piston 4. It should be noted that the 7 is held in this position because, if it tended to move back, the second channel 21 would be able to put the front chamber 16 in communication with the drain 19, which would have the effect of moving the stop piston 5 towards the 'before.
  • the striking piston 4 can strike the fitting 7 by sliding in its housing 31 under the effect of the pressure of the fluid of the main circuit 22.
  • the rotary motor can be actuated and act on the fitting 7 .
  • FIG. 4 and 5 is described hammer drill 101 according to the particular embodiment of the invention. We will describe hereinafter only the differences existing between this hammer drill 101 and that shown in Figures 1 to 3.
  • This hammer drill 101 has a body 102 and differs mainly from that shown in Figures 1 to 3 in that, d ' firstly, the stop piston 5 is now slid inside a guide 103 integral with the body 102, and secondly, the sleeve 6 is replaced by a sleeve 106 with an outer shoulder 107 and an internal recess. More specifically, the outer shoulder 107 has a first rear surface 108 intended to cooperate with the external circuit 23 and the inner recess has a second rear surface 109 offset from the first rear surface 108.
  • this second rear surface 109 is then put under the pressure of the drain 19.
  • a substantially annular chamber 110 is provided between the outer shoulder 107 and a rear end 111 of the guide 103, and this annular chamber 110 is connected to the main hydraulic supply circuit 22 .
  • the operation of the hammer drill 101 is similar to that described above for the hammer drill 1. It should be noted only that when the hammer drill 101 is fed by the main circuit 22, the underpressure fluid is delivered in the rear chamber 17 but also in the chamber 110.
  • the advantage of this particular embodiment of the invention lies in the fact that the front surface 25 and the rear surface 26 of the shoulder 12 of the stop piston 5, as well as the first and second surfaces
  • the backs 107, 108 of the liner 106 can be easily selected so that the minimum pressure generated by the external circuit 23 necessary for the displacement of the liner 106 is much greater than the pressure generated by the main circuit 22 in the rear chamber 17. and the room 110.
  • FIG. 6 describes a hammer drill 201 which differs from the hammer drill 101 shown in FIGS. 4 and 5 solely by the fact that the front face 13 of the stop piston 5 has a diameter substantially greater than that of the rear face 14. In operation, this has the effect of pushing the piston forward, even beyond its equilibrium position, because when the front chamber 16 and the rear chamber 17 are at an identical pressure, the difference in diameter between the front face 13 and the rear face 14 induces the creation of an additional annular section thrust forward. This then has the advantage of allowing the front face 13 of the stop piston 5 to remain longer in contact with the fitting 7 despite the important vibratory movements related to the percussion of the striking piston 4 on the fitting 7.
