    Background of the invention
    The present invention relates to the field of drilling in the ground, in particular to manufacture foundations, such as for example continuous screens consisting of juxtaposed concrete wall elements.
    More specifically, it relates to a drilling machine for making excavations in the ground in a substantially vertical direction of drilling, and more particularly in hard terrain. The invention relates more particularly to a machine having a lower part provided with cutting members and an upper part, the drilling machine having a longitudinal direction extending between the upper part and the lower part of the drilling machine, the machine drilling machine comprising: an anchoring module having a front face and a rear face, the anchoring module comprising at least one anchoring device which comprises at least one front anchor pad disposed on the front face and at least one skid a rear anchor disposed on the rear face, the front and rear anchor pads being deployable in a direction of deployment which is transverse to the longitudinal direction of the drilling machine, so as to bear against the walls of the excavation for immobilize the anchor module in the ground; a drilling module carrying the cutting members, the drilling module cooperating with the anchoring module.
    This type of drilling machine is generally used for drilling in hard ground, for example in granite. The displacement device allows to exert a complementary thrust on the drilling tools, which aims to facilitate the excavation.
    Such a machine is described in particular in EP 0 811 724. It is understood that the anchoring module makes it possible to immobilize the drilling machine in the excavation. However, this drilling machine does not effectively correct the drilling trajectory. The correction of the drilling path of the drilling machine requires changing its position in the trench. At the end of the position change, the drilling machine is generally not centered in the excavation but is closer to one of the larger walls than to the opposite wall. Also, the deployment of the anchor pads has the effect of refocusing the drilling machine in the excavation, which causes a change in the position of the machine and, as a result, again distorts the drilling path.
    Object and summary of the invention
    An object of the present invention is to provide a drilling machine for anchoring without changing the transverse position of the drilling machine in the excavation. The invention achieves its goal by the fact that the anchoring device comprises: a frame carrying the front and rear anchor pads, the frame supporting the drilling module; an actuator device to which the front and rear anchor pads are attached, the actuator device having a retracted state in which the front and rear anchor pads are retracted, and an expanded state in which the front and rear anchor pads are deployed, the actuator device acting on the front and rear anchor pads while being movable relative to the frame in a direction of displacement parallel to the deployment direction; whereby the assembly consisting of the front anchor pad, the rear anchor pad and the actuator device is movable relative to the frame and the drilling module in the direction of travel.
    It is understood that there is a slide connection between the assembly consisting of the front and rear anchor pads and the actuator device, on the one hand and the frame carrying the drilling module, on the other hand, this sliding connection being oriented in the direction of displacement transverse to the longitudinal direction. Advantageously, the assembly consisting of the front anchor pad, the rear anchor pad and the actuator device is freely movable relative to the frame and the drilling module in the direction of displacement. This is a montage called "floating".
    During anchoring, the actuator device deploys to bring the front and rear anchor pads in the deployed position. If for example the front anchor pad abuts against one of the walls of the excavation before the rear anchor pad, the actuator device and the rear anchor pad move transversely in the direction of movement relative to to the frame until the rear anchor pad comes in contact with the opposite wall. The deployment of the front and rear anchor pads and the displacement of the actuator device being performed relative to the frame and the drilling module, it is understood that the drilling module remains stationary during the anchoring phase. Also, thanks to the invention, the deployment of the front and rear anchor pads is performed without changing the transverse position, usually horizontal, the drilling module relative to the walls of the excavation.
    In other words, after correctly positioning the drilling module in the ground, the invention makes it possible to anchor the anchoring module in the ground without modifying the horizontal position of the drilling module. Thanks to the invention, the anchoring does not modify the drilling trajectory. The invention thus makes it possible, among other things, to improve the precision of the drilling trajectory.
    According to a first embodiment of the invention, the actuator device comprises a body slidably fixed to the frame in a direction parallel to the direction of movement. Thus, in this first embodiment, the actuator provides a dual function, namely to move the front and rear anchor pads, on the one hand, and to guide the displacement of the frame with the drilling module relative to the pads front and rear anchorage, on the other hand. In this first embodiment, the actuator device is fixed to the frame so that the sliding connection between the front and rear anchor pads is provided by the actuator device.
    Advantageously, the actuator device is a jack whose body is fixed to the frame slidably and to one of the front and rear anchor pads, while the rod of the jack is fixed to the other of the front anchor pads and back.
    According to a variant, the actuator device is a jack whose body is slidably fixed to the frame, the jack comprising a first rod fixed to the front anchor pad and a second rod, coaxial with the first rod, fixed to the pad of rear anchorage.
    According to a second embodiment, the anchoring device further comprises: a front guide device for guiding the displacement of the front anchor pad with respect to the frame in the direction of deployment; and / or a rear guide device for guiding the movement of the rear anchor pad with respect to the frame in the direction of deployment.
    The front and rear guide devices make it possible to guide the deployment of the front and rear anchor pads, as well as the relative displacement of the anchor pads and the actuator device with respect to the drilling module which remains stationary during the phase anchor.
    Another advantage of adding the front and rear guide devices is to transfer the longitudinal forces to them, so to separate the deployment functions of the pads and recovery of the longitudinal forces (vertical). This also allows the frame to take up more longitudinal forces, for example related to the weight of the drilling module, which has the effect of improving the robustness of the drilling machine.
    Preferably, in the second embodiment, the actuator device as such is not directly related to the frame. This mounting said "floating" has the effect that the frame can easily move relative to the assembly consisting of front and rear anchor pads and the actuator device.
    Preferably, the front guide device comprises at least a first front guide member which is fixed to the front anchor pad, the first front guide member being mounted to the frame slidably in a direction parallel to the deployment direction. .
    To do this, the frame comprises for example a hole in which the first front guide member is slidably mounted.
    To avoid disengagement of the first guide member from the frame, the first front guide member comprises a stop for limiting the displacement amplitude of the first front guide member in the frame.
    Preferably, but not exclusively, the stop is disposed at the end of the first front guide member which is opposite to the attachment portion of said first front guide member.
    Advantageously, to further improve the longitudinal force recovery capacity, the front guide device further comprises a second front guide member, identical to the first front guide member, the first and second front guide members being arranged on each side. other of the actuator device.
    Preferably, the rear guide device is similar to the front guide device.
    Thus, the rear guide device comprises at least a first rear guide member which is fixed to the rear anchor pad by a fixing portion, the first rear guide member being mounted to the frame slidably in a direction parallel to the deployment direction.
    Advantageously, to further improve the longitudinal force recovery capacity, the rear guide device further comprises a second rear guide member, identical to the first rear guide member, the first and second rear guide members being arranged on each side. other of the actuator device.
    Advantageously, the front and rear anchor pads are fixed to the actuator device in an articulated manner. This articulation, comprising at least one horizontal axis pivot connection, and preferably a ball joint, allows the front and rear anchor pads to be positioned parallel to the walls of the excavation. This has the effect of maximizing the contact area between the anchor pads and the walls of the excavation, which improves the anchoring of the anchor module in the excavation.
    Preferably, with reference to the second embodiment, the front anchor pad is attached to the front guide device in an articulated manner, and the rear anchor pad is attached to the rear guide device in an articulated manner.
    Still preferably, each of the front and rear anchor pads is hinged relative to the first and second front and rear guide members.
    Advantageously, the assembly consisting of the front anchor pad, the rear anchor pad, the front guide device and the rear guide device forms a deformable trapezium, the frame of the anchoring module with the drilling module. being movable relative to said deformable trapezium in the direction of displacement. When the anchor pads are deployed, the deformable trapezium constitutes a rigid one-piece structure for guiding the displacement of the drilling module relative to non-strictly vertical walls of the excavation, to ensure effective anchoring, while supporting the module anchor.
    According to a preferred embodiment, the actuator device comprises at least one jack. According to a variant, the actuator device comprises two parallel cylinders arranged side by side.
    According to another advantageous aspect of the invention, the drilling machine further comprises a displacement device disposed between the anchoring module and the drilling module to move the cutting members relative to the anchoring module in the longitudinal direction. of the drilling machine.
    The longitudinal displacement of the cutting members is advantageously achieved once the anchor module is anchored in the ground, which allows in particular to exert a thrust directed downwards on the cutting members. To do this, the displacement device acts on the drilling module to move it downwards in the longitudinal direction. The drilling machine then has an extended position in which the cutting members are remote from the anchoring module, and a retracted position in which the cutting members are brought close to the anchoring module.
    Advantageously, the drilling module has a lower section carrying the cutting members and an upper section extending in the longitudinal direction, the upper section of the drilling module being suspended at the lower end of a lift cable.
    It is understood that, according to the invention, the lift cable is fixed to the drilling module, unlike the document of the prior art EP 0 811 724 wherein the lift cable is fixed to the anchor module. According to the invention, the actuation of the lift cable can cause the displacement of the drilling module relative to the anchor module in the longitudinal direction, when said anchoring module is anchored in the ground.
    An interest is to reduce the load borne by the displacement device when the anchoring module is not anchored in the ground. The displacement device now only carries the anchoring module, which is lighter than the drilling module.
    Advantageously, the displacement device comprises at least one thrust cylinder disposed between the frame of the anchoring device and the lower section of the drilling module, the upper section of the drilling module being movable relative to the frame of the device. anchoring in said longitudinal direction.
    It is understood that the actuation of the thrust cylinder has the effect of lowering the lower section of the drilling module carrying the cutting members, the cooperation between the upper section and the drilling module for guiding the displacement.
    According to a preferred variant, the upper section is a bar which extends longitudinally through the anchoring module. This bar is slidably mounted relative to the frame of the anchoring device.
    Advantageously, the anchoring module comprises a plurality of anchoring elements, the frames of the anchoring elements being integral with each other, in order to form a framework. The upper section of the drilling module is preferably slidably mounted relative to this framework. To do this, the frame may comprise guide members forming sleeves in which the upper section, and in particular the bar, is slidably mounted.
    According to an advantageous aspect of the invention, the drilling module further comprises trajectory correction means for pivoting the drilling module in a vertical plane. The actuation of the path correction means makes it possible to correct the position of the cutting members by modifying the spatial position of the drilling module in the excavation. After which we deploy the anchor pads to immobilize the anchor module in the ground. The displacement of the front and rear anchor pads being effected without displacement of the drilling module, thanks to the fact that the front and rear anchor pads together with the actuator device are movable relative to the frame carrying the drilling module.
    Then, the actuation of the displacement device has the effect of exerting a thrust on the cutting members pointing downwards in the corrected drill direction, thus allowing drilling to continue in the desired direction.
    Advantageously, the trajectory correction means comprise trajectory correction pads that are deployable in a direction transverse to the drilling module to abut against at least one of the walls of the excavation in order to rotate the module. drilling in the vertical plane.
    When the trajectory correction pad abuts so as to exert a thrust against the excavation wall, this causes the displacement of the drilling module in a direction opposite to the direction of deployment of the trajectory correction pad.
    The trajectory correction pads are arranged on the front face and on the rear face of the drilling module.
    Preferably, the trajectory correction pads are arranged in the upper section and / or in the lower section of the drilling module.
    To facilitate the pivoting of the drilling module, the trajectory correction pads are arranged on the front face and on the rear face of the upper and lower sections of the drilling module.

    Detailed description of the invention
    Figures 1 and 2 illustrate an example of a drilling machine 10 according to the present invention. This drilling machine 10 is designed to perform an excavation E in soil S in a drilling direction F which is substantially vertical. In other words, the drilling machine 10 according to the invention is designed to make vertical trenches in the ground. The drilling machine 10 has a longitudinal direction L which extends between an upper portion 12 and a lower portion 14 of the drilling machine 10.
    As can be seen in FIG. 1, the lower part 14 is provided with cutting members 16 which, in this nonlimiting example, comprise two pairs of drums 18, 20 which are rotatably mounted about axes of rotation A, B parallel and distant from each other. The axes of rotation A and B are orthogonal to the longitudinal direction L of the drilling machine 10. Furthermore, the pairs of drums 18, 20 are provided at their periphery with cutting teeth 22, which are moreover known. In other words, in this example, the drilling machine 10 is a cutter adapted to make the vertical trenches in the ground.
    The drilling machine 10 also comprises an anchoring module 30 which has a front face 32 and a rear face 34, opposite to the front face 32. When the excavating machine is in the ground, the front 32 and rear faces 34 are vis-à-vis the largest walls PI, P2 of the excavation E. The smaller excavation walls P3, P4 are perpendicular to the largest walls PI, P2 excavation E, and are visible in Figure 2.
    The anchoring module 30 comprises a plurality of anchoring devices 40 which have the function, when they are actuated, of immobilizing the anchoring module in the ground. These anchors will be described in more detail below.
    The drilling machine 10 further comprises a drilling module 50 which is disposed in the lower part 14 of the drilling machine, the drilling module 50 carrying the cutting members 16.
    In this example, the drilling module 50 is movable in translation relative to the anchoring module in the longitudinal direction L. To move the drilling module 50 relative to the anchoring module 30, the drilling machine 10 further comprises a displacement device 60 which is arranged between the anchoring module 30 and the drilling module 50. In this example, the displacement device 60 consists of two thrust cylinders 62, 64 whose function is to exert a thrust on the cutting members 16 when the anchoring module is anchored in the ground, this thrust in the longitudinal direction directed downwards.
    The drilling module 50 further comprises a lower section 52 which carries the cutting members and an upper section 54 which extends from an upper end 52a of the lower section of the drilling module 50 in the longitudinal direction L. Moreover, as can be seen in FIG. 2, the upper section 54 of the drilling module 50 is a bar 56 which extends longitudinally through the anchor module 30. Referring to FIG. 2, it can be seen that the upper section 54 of the drilling module 50 is suspended at the lower end 71a of a levitation cable 71. This levitation cable is connected to the upper end of a mast of a carrier (not shown here), known elsewhere.
    It will be understood that the displacement device 60, in particular the thrust cylinders 62, 64, is disposed between a lower end 30b of the anchoring module 30 and the upper end 52a of the lower section 50 of the lower section 52 of the module. drilling 50. With the aid of Figure 3, we will now describe in more detail the anchoring device 40 corresponding to a first embodiment of the invention.
    Each anchoring element 40 comprises a front anchor pad 42 disposed on the front face 32 of the anchoring module 30 and a rear anchor pad 44 disposed on the rear face 34 of the anchoring module 30. As can be understood from FIG. With the aid of FIG. 3, the front and rear anchor pads are deployable in a deployment direction D which is transverse to the longitudinal direction L of the drilling machine 10. The front and rear anchoring pads 44 and 44 present a retracted position and an extended position, illustrated in Figure 3 in which the anchor pads abut against the largest walls PI, P2 of the excavation E to immobilize the anchor module 30 in the ground S.
    To improve the anchoring, the front and rear anchor pads are provided with brackets 46 in this example, which are arranged on the outer faces of the anchor pads which are facing the walls.
    The anchoring device 40 further comprises a frame 70 which carries the front and rear 32 and 34 anchor pads. As can be understood from FIG. 2, the frame 70 is fixed to the displacement means 60 so that that the frame 70 supports the drilling module 50; more specifically in the non-limiting example of Figure 2, the anchor module 30 comprises a plurality of anchoring devices 40 whose frames 70 are integral with each other to form a frame that supports the drilling module 50 through the displacement device 60, in this case via the thrust cylinders 62, 64. It is therefore understood that when the drilling machine is suspended in the air at the end of the lift cable 71, the cylinders 62, 64 support only the weight of the anchor module.
    Referring again to FIG. 3, it can be seen that the anchoring device 40 further comprises an actuator device 72 to which the front and rear 32 and 34 anchor pads 34 are attached. In this example, the actuator device 72 is a hydraulic jack 74 which comprises a body 76 fixed to the front anchor pad 42, and a rod 78 fixed to the rear anchor pad 44. In this first embodiment, the body 76 of the jack 74 is fixed to the frame 70 so as to sliding in a direction transverse to the longitudinal direction of the drilling machine; in this case, it is the deployment direction. The hydraulic cylinder 74 forms a slide connection with the frame 70 oriented in the direction of deployment.
    To do this, the body 76 has a lumen 78 which cooperates with a guide pin 79 of the frame 70.
    The actuator device 72 has a retracted state in which the front 42 and rear 44 anchor pads are retracted and an expanded state, illustrated in Figure 3, in which the front 42 and rear 44 anchor pads are deployed. The actuator device 72 is therefore adapted to act on the front 42 and rear anchor pads 44 while being movable relative to the frame 70 in a direction of displacement D2 which is transverse to the longitudinal direction of the drilling machine. In this example, the displacement direction D2 corresponding to the deployment direction D1.
    It is therefore understood that the assembly consisting of the front anchor pad 42, the rear anchor pad 44 and the actuator device 72 (the jack 74) is movable relative to the frame 70 and the drilling module in the direction of displacement D2.
    Referring again to Figure 3, it is found that in this first embodiment, each of the front 42 and rear anchor pads 44 is attached to the actuator device 72 in an articulated manner. More specifically, the front anchor pad 42 is pivotally mounted about an axis X substantially horizontal relative to the actuator device 72. Similarly, the rear anchor pad 44 is also pivotally mounted about a Y axis by relative to the actuator device 72.
    As can be understood from FIG. 3, this articulated mounting advantageously allows the front and rear anchor pads 44 to tilt and bear flat against the walls P1, P2 of the excavation E, the latter are not necessarily strictly vertical, especially if the drilling trajectory has deviated with respect to the desired trajectory, nor parallel to each other.
    The anchoring device 40 'illustrated in FIG. 4 is a variant of the anchoring device 40 illustrated in FIG. 3. The variant of FIG. 4 differs from the device of FIG. 3 in that the actuator device 72' is a cylinder 74 'provided with a body 76' movably connected to the frame 70 'and two coaxial rods 78'a and 78'b. The first rod 78'a is fixed to the front anchor pad 42 'in an articulated manner, while the second rod 78'b is hingedly attached to the rear anchor pad 44'. When actuating the actuator device 72 ', the first and second rods 78'a and 78'b unfold in an opposite manner in order to bring the front and rear anchor pads against the walls PI, P2 of the excavation . With the aid of FIGS. 5 to 7, a second embodiment of the anchoring device 140 according to the invention will now be described.
    The anchoring device 140 comprises a front anchor pad 142 which is disposed on the front face 32 of the drilling module 30 of the drilling machine 10 of FIG. 1, and a rear anchor pad 144 which is arranged opposite rear 34 of the drilling module 30 of the drilling machine 10 of Figure 1. Similarly to the first embodiment, the front and rear anchor pads are deployable in a deployment direction DI which is transverse to the longitudinal direction L of the drilling machine 10, so as to bear against the walls PI, P2 of the excavation E to immobilize the anchoring module in the ground.
    The anchoring device 140 further comprises a frame 170 which supports the drilling module 50 via the displacement device 60 previously described.
    The anchoring device 140 further comprises an actuator device 172 to which the front and rear anchor pads 142 and 144 are attached.
    In this second embodiment, the actuator device 172 comprises a first cylinder 1741 and a second cylinder 1742, each of the first and second cylinders 1741, 1742 comprises a rod 1781, 1782 hingedly attached to the rear anchor pad 144, via pivot links of axes Y1, Y2 substantially horizontal. The first and second cylinders 1741, 1742 each comprise a body 1761, 1762 which is hingedly attached to the front anchor pad 142 via pivot links of axes XI, X2 which are substantially horizontal.
    The actuator device 172 has a retracted state, illustrated in FIG. 5, in which the front and rear anchor pads 142 are retracted, and an expanded state, illustrated in FIG. 6. According to the invention, the actuator device 172 is movable relative to the frame 170 in the direction of displacement D2, which is in this example coincides with the deployment direction Dl.
    Unlike the first embodiment, the actuator device 172 is not directly connected to the frame 170.
    Without departing from the scope of the invention, the actuator device 172 could comprise only one cylinder.
    As can be seen in FIG. 5 and FIG. 6, in this second embodiment, the anchoring device further comprises a front guide device 180 for guiding the displacement of the front anchor pad 142 relative to the frame 170. according to the deployment direction Dl. The forward guide device 180 includes a first front guide member 182 which is attached to the front anchor pad 142 by a fastener portion 184. The first front guide member 182 is slidably mounted to the frame 170 in the direction of Dl deployment. To do this, the first front guide member 182 is slidably mounted in an orifice 186 formed in the frame 170. The first front guide member 182 also has a stop 187 which is disposed at the end of the first front guide member. 182 opposite the fixing portion 184. The purpose of this stop is to prevent the first front guide member from disengaging the frame. In addition, the first front guide member 182 is fixed to the front anchor pad 142 in an articulated manner, via a rotational axis pivot link X3 parallel to the axes XI and X2 described above.
    The front guide device 180 further comprises a second front guide member 188, identical to the first front guide member 182, the first and second front guide members 180, 188 being disposed on either side of the actuator device 172. It is specified that the second front guide member 188 is also fixed to the front anchor pad 142 in an articulated manner.
    Insofar as the first and second front guide members are slidably mounted in the frame 170, the articulation between the second front guide member 188 and the front anchor pad 142 is adapted to allow a slight translation in the longitudinal direction. L to allow the anchor pad before tilting relative to the rear anchor pad.
    The anchoring device 140 further comprises a rear guide device 190 for guiding the displacement of the rear anchor pad 144 with respect to the frame 170 in the deployment direction D1. The rear guide device 190 is very similar to the front guide device 180, so that it will be described more succinctly. The rear guide device comprises a first rear guide member 192 which is fixed to the rear anchor pad 144 hinged about an axis of rotation Y3 parallel to the axes Y1 and Y2, the first rear guide member 192 also being mounted to frame 170 slidably in the direction of deployment Dl. The rear guide device 190 further comprises a second rear guide member 198 identical to the first rear guide member 192, the first and second rear guide members being disposed on either side of the actuator device 172. In addition, in this second embodiment, the first and second front guide members 182, 188 are disposed on either side of the first and second rear guide members 192,198.
    FIG. 7 illustrates the situation in which the walls of the excavation P1, P2 are neither strictly vertical nor exactly parallel to one another. After actuation of the actuator device 172, the front and rear anchor pads 142, 144 are positioned flat against the walls PI, P2 of the excavation; insofar as the wall PI is not parallel to the wall P2, it is understood that the front anchor pads 142 and back 144 are inclined relative to each other. Also, the assembly consisting of the front anchor pad 142, the rear anchor pad 144 of the front guide device 180, and in particular the first and second front guide members and the guide device 190, and in particular the first and second second rear guide members, forms a trapezium.
    Insofar as the frame 170 is slidably mounted in the deployment direction D1 relative to the first and second front and rear guide members 182, 188, 192, 198, it is understood that the frame 170 can move in the direction of deployment. Dl which then constitutes the direction of displacement D2 even though the anchor module is anchored in the ground. As a result, the frame 170 of the anchoring module 30 with the drilling module 50 are movable relative to the trapezium in the direction of displacement D2.
    FIG. 8 schematically illustrates a drilling machine 10 according to the invention which comprises two anchoring devices 140 such as those illustrated in FIGS. 5 to 7, except that the actuating device of each of the anchoring devices comprises only one cylinder referenced 174. With the aid of this figure 8, it is understood that the frames 170 of the anchoring devices 140 carry the drilling module 50, and in particular the lower section 52. It is also understood that the drilling module 50 is slidably mounted relative to the anchoring module 30. As can be understood from FIG. 8, the anchor frames 170 are preferably integral with one another via connecting members 73 which improves the rigidity of the anchoring module.
    Referring again to FIGS. 1 and 2, it can be seen that the drilling module 50 further comprises trajectory correction means 90 for pivoting the drilling module in a vertical plane Q1 which is parallel to the axes of rotation A, B drums 18, 20.
    These trajectory correction means 90 comprise first trajectory correction pads 92 arranged on the front face of the lower section which are deployable in a direction T, parallel to the axes of rotation A, B of the drums, to bear against at least one of the walls PI, P2 of the excavation E in order to rotate the drilling module in the vertical plane Ql. In this example, the trajectory correction means 90 further comprise second trajectory correction pads 94 arranged on the rear face of the lower section 52 of the drilling module 50. The deployable pads 92, 94 are arranged in this example in section. bottom of the drilling module. It could also be provided other deployable pads disposed in the upper section of the drilling module, to facilitate the pivoting of the drilling module in the vertical plane Ql. With the aid of FIGS. 9A to 10D, the operation of the trajectory correction means will now be described in more detail.
    In the example of FIG. 9A, the drilling trajectory F of the drilling machine 10 has deviated by an angle Θ with respect to the vertical direction V.
