Definitions

• It relates more precisely to the field of drilling machines for making excavations in the ground in a substantially vertical direction of drilling.
• An object of the present invention is to remedy the aforementioned drawbacks by proposing an anchoring kit which can be mounted on an existing standard drilling machine.
• anchoring kit is intended to be mounted on an existing standard machine devoid of anchoring module.
• anchoring module means a module making it possible to immobilize part of the drilling machine in the ground, by resting on the walls of the trench.
• the anchoring kit therefore constitutes a structural unit distinct from the drilling machine which is attached to an existing and operational drilling machine.
• the anchor kit is mounted on the drilling machine by by means of the fixing device which fixes the second part to the chassis.
• the anchoring device When the anchoring device is actuated, the first part is immobilized in the ground. It is in particular blocked in the vertical direction. Then, when the displacement device is actuated, the second part is moved relative to the first part which remains fixed. The displacement device therefore applies a force to the second part, which force is transmitted to the chassis and to the drilling module.
• the fact that the first part is immobilized in the ground makes it possible to apply a significant force to the drilling module, which facilitates the drilling of hard terrains.
• the displacement of the second part relative to the first part is a translation.
• the second part preferably comprises a guide shoe to facilitate the vertical sliding of the second part along a wall of the trench.
• the movement device advantageously comprises an actuator connected to the first part and to the second part of the first anchoring module.
• the actuator is advantageously disposed between the first part and the second part of the first anchoring module.
• this actuator can exert a push or a pull on the second part.
• several actuators can be provided between the first and the second part.
• the anchoring kit is supplied with energy by the drilling machine.
• the actuator comprises a hydraulic cylinder
• the anchoring kit further comprises a hydraulic connection connected to the hydraulic cylinder, the hydraulic connection being configured to be connected to a hydraulic hose of the chassis.
• the presence of the hydraulic connection allows easy mounting of the anchoring kit to the standard drilling machine and rapid installation of the anchoring kit to the drilling machine.
• the anchoring device comprises a first and a second anchoring pads deployable in a second direction which is transverse to the first direction, the direction of deployment of the first pad being opposite to the direction of deployment of the second pad.
• the first and second anchoring pads are deployed and bear against the opposite walls of the trench, preferably the two largest walls, which immobilizes the first part in the trench.
• first and second anchor pads can alternately be deployed so as to come into abutment against the two smallest walls of the trench.
• the first part further comprises a body
• the anchoring device comprises an actuator connected to the first and second pads, the actuator being slidably mounted relative to the body in a third direction transverse to the first direction.
• the anchoring of the anchoring device in the trench does not cause the body to move according to the third direction.
• One advantage is to avoid moving the chassis during anchoring in the trench, which allows not to deviate from the drilling trajectory.
• the first anchoring module further comprises a guide system for guiding the movement of the chassis relative to the first part.
• This guidance is advantageously carried out in the first direction.
• the guide system has the function of guiding the movement in vertical translation of the chassis relative to the first part.
• the guide system comprises a first portion and a second portion mounted to slide relative to the first portion in the first direction, in which the second portion comprises members for fixing to the chassis, while the first portion is fixed to the device. anchor.
• the anchoring kit further comprises a second anchoring module and, preferably, a connecting device for securing together the first and second anchoring modules.
• connection device comprises a passage for guiding the movement of the chassis, in which the displacement device comprises a first actuator disposed between the connecting device and the second part of the first anchoring module and a second actuator arranged between the connecting device and the second part of the second anchoring module.
• the anchoring kit also comprises a second anchoring module which comprises a second part fixed to the chassis.
• the lower part of the chassis is provided with a pump, said drilling module being provided with rotary cutting drums around axes perpendicular to the longitudinal direction, in which the length of the drilling machine is less than 7 meters.
• the length of the kit is substantially equal to the length of the chassis.
• the modification method according to the invention comprises fixing the second part of the second anchoring module to the chassis, on the face opposite to that receiving the second part of the first anchor module.
• FIG. 4 is a detail view of the anchoring kit according to the first embodiment
• FIG. 7 illustrates the machine of Figure 6, the displacement device being retracted to exert on the drilling module a force directed downwards;
• anchoring kit ÎOO constitutes an added structural unit which is distinct from the drilling machine 10.
