Abstract
The present invention relates to a drilling machine (10) for carrying out excavation in the ground (S) in a vertical drilling direction (F). Said drilling machine comprises: a mounting (12) having a longitudinal direction (L); a drilling module (14) provided with cutting members (16), the drilling module being translatable relative to the mounting; and a movement device, arranged between the mounting and the drilling module, for moving the drilling module (14) relative to the mounting in the longitudinal direction of the mounting. The movement device comprises an absorption device (70) for absorbing the vibrations generated by the drilling module while carrying out the drilling. The invention is characterized in that the movement device includes at least one hydraulic actuator (62, 64), the absorption device includes a hydraulic damper device (72), wherein the hydraulic actuator and the hydraulic damper device are in fluid flow connection via large chambers (62a, 64a) of the hydraulic actuators.
Claims (10)
1. A drilling machine for making an excavation in ground in a drilling direction that is substantially vertical, said drilling machine comprising: 5 a support having a longitudinal direction; a drilling module provided with cutter members, the drilling module being movable in translation relative to the support along the longitudinal direction of the support; and 10 a movement device arranged between the support and the drilling module in order to move the drilling module relative to the support along the longitudinal direction of the support; the movement device including at least one hydraulic 15 actuator connecting the support to the drilling module and damper means for damping the vibration generated by the drilling module while drilling, the damper means comprising a hydraulic damper device in fluid flow connection with the hydraulic actuator.
2. The drilling machine according to claim 1, wherein the drilling module has a bottom section carrying the cutter members, and a top section that passes longitudinally through said support, the top section being slidably 25 mounted relative to said support and presenting a top end connected to a bottom end of a lift cable.
3. The drilling machine according to claim 2, wherein the support is a frame, the transverse dimensions of 30 which, considered in a plane perpendicular to the longitudinal direction, are substantially equal to or less than the transverse dimensions of the drilling module, and wherein said frame includes an anchor device suitable for preventing the frame from moving relative to 35 the walls of the excavation.
4. The drilling machine according to claim 1, wherein the support comprises a boom, wherein the cutter members are situated at a bottom end of a bar of the drilling module, and wherein the movement device comprises a carriage
5.mounted on the boom to be slidable along the longitudinal direction of the boom, the carriage co-operating with said bar to move the drilling module along the longitudinal direction of the boom. 10 5. The drilling machine according to claim 4, wherein the carriage includes the damper means.
6. The drilling machine according to claim 5, wherein the carriage comprises a first portion slidably mounted 15 on the boom, a second portion co-operating with the bar, and wherein the damper means are arranged between the first and second portions of the carriage.
7. The drilling machine according to any one of the 20 preceding claims 1 to 6, wherein the drilling module further comprises an anti-swinging device to prevent horizontal movement of the drilling module while drilling. 25
8. The drilling machine according to claim 7, wherein the anti-swinging device comprises deployable pads arranged on lateral sides of the drilling module and arranged to co-operate with the walls of the excavation. 30
9. The drilling machine according to any one of the preceding claims 1 to 8, further comprising a device for regulating the damping coefficient of the damper means.
10. The drilling machine according to any one of the 35 preceding claims 1 to 9, wherein the drilling machine is a milling machine having cutter members comprising two pairs of drums that are rotatable about axes of rotation that are parallel to each other, distinct from each other, and each perpendicular to the longitudinal direction of the support.
