- the device is mounted on a feed device, which allows the tool to create a pressing force on the ground during drilling.
- Figure 1 of the accompanying schematic drawing shows a device of known type.
- This device comprises a hammer drill 2 equipped with a tool 3 associated with a rotary drive device 4 and a striking device 5.
- a distributor 6 makes it possible to reciprocate the piston 7 of the striking device 5.
- the rotary hammer is mounted movable with respect to the terrain in which drilling is to be carried out, using an advance system mounted on slides.
- the advance system 9 comprises a hydraulic jack whose rod 10 is supported on a fixed point 12. The advance system is guided by slides 13.
- the apparatus also comprises a device 14 for sucking the dust entrained by a hydraulic motor 15.
- the various movements are obtained from a source of hydraulic fluid under pressure through a flow divider 16, for example of the gear or static type, which supplies via four distributors 1 7, 1 8, 19 and 20 respectively the hydraulic motor of the rotary drive device, the impact device, the cylinder of the advance system, and the hydraulic motor of the dust suction device.
- the connections are made through a series of hoses.
- Known rotary percussive drilling rigs are characterized by different hydraulic flow rates and pressures depending on the movements controlled.
- the highest pressure is that of the dust extraction device 14, 1 5 and of the advance system 9-1 3.
- the pressure of the impact device 5 represents approximately two thirds of the value of the highest pressure, while the pressure of the rotary drive device 4 represents about one third of the highest pressure.
- the essential advantage of this device is its simplicity, since the power supplies of the different movements are independent of each other, and do not require any component other than distributors to perform all the functions.
- the main drawback lies in the significant pressure differences between the bodies of the flow divider 1 6. Taking into account the technology used for this type of hydraulic component, these significant differences in pressure induce leaks of hydraulic fluid between the bodies of the divider , which results in a low hydraulic efficiency of the hydraulic supply device of the drilling rig.
- the object of the invention is to provide a hydraulic supply device of this type, making it possible to minimize the pressure differences between the different actuators and, consequently, to improve the hydraulic efficiency of the device, without using complex technical solutions, particularly from a hydraulic point of view.
- the device according to the invention intended for the hydraulic supply of a rotary percussive drilling apparatus whose tool is, on the one hand, driven in rotation in one direction or the other and, on the other hand, subjected to the action of a striking device acting independently of the rotation, of a hydraulic advance device allowing the tool to create a bearing force on the ground, and possibly a drilling dust suction device, driven by a hydraulic motor, the various hydraulic actuators being driven from a source of hydraulic fluid under pressure through a hydraulic flow divider, a set of distributors and a set of pipes outside the device, such as hoses, is characterized in that it comprises a pipe for communicating the return pipe of the hydraulic device for rotating the tool and the line d al imentation of the impact device, to add to the feed rate of the impact device, the return rate of the rotary drive device.
- one of the ends of the connection pipe of the return pipe of the hydraulic device for driving the tool in rotation and of the supply line of the impact device is connected to the control distributor of the
- connection pipe for the return of the hydraulic device and the supply of the impact device is located outside the two hydraulic actuators respectively in rotation and in impact, so that a device for known structure can be used with the implementation of a hydraulic motor which is integrated into the device or independent of it, while offering a simple technical solution both in the production of the connecting pipe and in the maintenance of that -ci, since this connection is made outside the main part of the device.
- the connection pipe for the return pipe of the hydraulic device for driving the tool in rotation and the supply line for the impact device consists of the discharge line. liquid from the rotary drive device, which opens into the supply line of the impact device, upstream of the feed control distributor thereof.
- connection pipe for the return pipe of the hydraulic device for rotating the tool and the supply line for the striking device opens into this line d supply of the striking device, downstream of the feed control distributor thereof.
- the connecting pipe of the return pipe of the hydraulic device for driving the tool in rotation and the supply line of the striking device opens out, on the one hand, in this supply line for the impact device and, on the other hand, in a valve for communicating the return pipe of the drive device in rotation and of the striking device supply line, this valve being piloted and bringing the two circuits into communication when the striking device is actuated.
- the valve for communicating the two circuits is controlled by a pressure tap on the supply line of the impactor.
- the return line of the hydraulic rotary drive motor is connected to the reservoir, while when the impactor is in operation, the valve is actuated in order to channel the hydraulic fluid from output from the rotary drive to the supply line of the impactor.
- FIGS 2 to 4 are three schematic views similar to Figure 1 showing three embodiments of this hydraulic supply device.
- FIGS. 2 to 4 the same elements are designated by the same references as in FIG. 1.
- the return pipe 22 of the rotary drive device 4 of the tool is placed in communication with the supply line 23 of the striking device, by means of the line 24 for discharging liquid from the rotary drive device, after passing through the distributor 1 7.
- the line 24 opens into the supply line 23 of the impactor, in the area of the latter between the flow divider 1 6 and the distributor 18.
- the rotary drive device is supplied with hydraulic liquid, and the striking device does not work, the liquid is evacuated through the distributor 1 8 towards the reservoir 25. This is the position shown in FIG. 2.
- the distributor 1 8 is in its position for supplying the striking device, the return flow from the rotary drive device comes s '' add to the feed rate of the impactor.
- the device comprises a tube 26 for communicating the return pipe of the hydraulic device for rotating the tool and the pipe 23 of the supply line of the striking device. This tubing 26 opens into line 23 downstream of the distributor 18 for controlling the supply of the striking device.
- the rotational drive device 4 is powered to be able to rotate in both directions.
- the distributor 1 7 is arranged to be able to cross feed the two supply and return lines of the device 4 so that the supply line can be used as a return line and vice versa.
- the tubing 26 is connected to the distributor 1 7, and is placed in communication with the return line 22, this return line being the high and low line in the drawing, that is to say that not carrying out the supply of the device 4.
