Abstract

The invention relates to an anchoring kit for a drilling machine provided with a frame, the anchoring kit including at least a first anchoring module having: a first part including an anchoring device for immobilizing the first part in the soil; a second part including a device for fixing to the frame; and a displacement device for moving the second part relative to the first part along a first direction.

First claim

The invention claimed is:

1. A removable anchoring kit for a drilling machine comprising a frame which carries a drilling module, the removable anchoring kit including at least a first anchoring module comprising:
a first part including an anchoring device for immobilizing the first part in soil, wherein the anchoring device is a structural unit distinct from the drilling machine that is configured to be selectively added to the drilling machine to apply additional force to the drilling module;
a second part including a removable fixing device for removably fixing the second part to the frame, the second part cooperating with the first part; and
a displacement device for moving the second part relative to the first part along a first direction, wherein the displacement device of the first anchoring module includes an actuator connected to the first part and to the second part of the first anchoring module, and wherein the anchoring device includes a first and a second anchoring pad which are deployable along a second direction transverse to the first direction, the direction of deployment of the first anchoring pad being opposite to the direction of deployment of the second anchoring pad,
wherein the actuator comprises a hydraulic cylinder, and wherein the removable anchoring kit further includes a removable hydraulic fitting connected to the hydraulic cylinder, the removable hydraulic fitting being configured to be removably connected to a hydraulic hose of the frame.

2. The removable anchoring kit according to claim 1 , wherein the first part further includes a body, and the anchoring device includes at least one actuator connected to the first and second anchoring pads, the at least one actuator being slidably mounted relative to the body along a third direction transverse to the first direction.

3. The removable anchoring kit according to claim 1 , wherein the first anchoring module further includes a guide system for guiding the displacement of the frame relative to the first part.

4. The removeable anchoring kit according to claim 3 , wherein the guide system includes a first portion and a second portion slidably mounted relative to the first portion, wherein the second portion includes members for fixing the second portion to the frame, and wherein the first portion is fixed to the anchoring device.

5. The removable anchoring kit according to claim 1 , further including a second anchoring module.

6. The removeable anchoring kit according to claim 5 , further including a connecting device for securing together the first and second anchoring modules.

7. The removeable anchoring kit according to claim 6 , wherein the connecting device includes a passage for guiding displacement of the frame, wherein the displacement device includes a first actuator disposed between the connecting device and the second part of the first anchoring module and a second actuator disposed between the connecting device and the second part of the second anchoring module.

8. A drilling machine, comprising:
a frame extending along a longitudinal direction and having a lower part carrying a drilling module including at least a first anchoring module, the first anchoring module comprising:
a first part including an anchoring device for immobilizing the first part in the soil;
a second part being fixed to the frame; and
a displacement device for moving the second part relative to the first part along a first direction, the displacement device comprising at least an actuator connected to the first part and to the second part of the first anchoring module;

wherein the anchoring device includes a first and a second anchoring pad which are deployable along a second direction transverse to the first direction, the direction of deployment of the first anchoring pad being opposite to the direction of deployment of the second anchoring pad, wherein the first part is between the second part and the drilling module, and wherein the actuator is configured to exert a downward pull on the second part causing the second part to move towards the first part and thereby cause the frame and on the drilling module to move downward relative to the first part.

9. The drilling machine according to claim 8 , wherein the lower part of the frame is provided with a pump, the drilling module being provided with cutting drums rotating about axes perpendicular to the longitudinal direction, in which the length of the drilling machine is less than 7 meters.

10. The drilling machine according to claim 8 , wherein the first part further includes a body, and the anchoring device includes at least one actuator connected to the first and second anchoring pads, the at least one actuator being slidably mounted relative to the body along a third direction transverse to the first direction.

11. The drilling machine according to claim 8 , wherein the first anchoring module further includes a guide system for guiding the displacement of the frame relative to the first part.

12. The drilling machine according to claim 11 , wherein the guide system includes a first portion and a second portion slidably mounted relative to the first portion, wherein the second portion includes members for fixing the second portion to the frame, and wherein the first portion is fixed to the anchoring device.

13. The drilling machine according to claim 8 , further including a second anchoring module.

14. The drilling machine according to claim 13 , further including a connecting device for securing together the first and second anchoring modules.

15. The drilling machine according to claim 8 , wherein the actuator comprises a hydraulic cylinder and wherein the displacement device is arranged so that the actuation of the displacement device brings the hydraulic cylinder in retracted position.
