Definitions

• a device preferably for performing of a drilling in earth-layer and rock
• the present invention refers to a device in the first place for performing of a drilling in earth-layers and rocks, whereby a first unit is used comprising a countersink hammer, which by aid of its strokes acts towards a bore crown for drilling of a bore hole at the same time as a driving downwards can be provided by a casing pipe in the bore hole made together with the bore crown used and a second unit for feeding pressurized air to in the first place to the first unit for its operation.
• a first unit comprising a countersink hammer, which by aid of its strokes acts towards a bore crown for drilling of a bore hole at the same time as a driving downwards can be provided by a casing pipe in the bore hole made together with the bore crown used and a second unit for feeding pressurized air to in the first place to the first unit for its operation.
• One object of the present invention is to eliminate those drawbacks existing with known drilling devices of the type i.a. mentioned above by providing a new thinking and a new device in the first place in connection with drilling in earth-layers and rocks.
• the characterizing features of the present invention are set forth in the claims enclosed.
• the energy consumption has been able to be lowered to about. 20.000 - 30.000 litres of oil and year.
• the high pressure compressor integrated with the load vehicle can of course also be used for other purposes such as i.e. transporting bulk material in pipe lines when i.e. emptying of ships and cleaning and regenerating of pipes in oil refinerys.
• Fig. 1 shows a schematic perspective view of a device according to the invention comprising a load vehicle with an integrated high pressure compressor
• Fig. 2 shows a schematic perspective view of the high pressure compressor itself illustrated in fig. 1 ,
• Fig. 3 shows a schematic side view of the power transmission between the power take off from the gear box of the load vehicle and the primary shaft to the high pressure compressor
• Fig. 4 shows a perspective view in a greater scale of the operating unit according to the invention.
• the same consists of a device for performing of a drilling in earth layer and rocks.
• a first unit comprising a counter sink hammer, which by its strokes acts towards a bore crown for drilling a bore hole at the same time as a driving downwards can be done of a casing pipe into the bore hole made together with the bore crown used.
• a second unit is on the other especially intended to feed that pressure air needed for the operation of the first unit.
• the second unit 1 comprises a high pressure compressor 3 mounted on a load vehicle 2, which is connected to and is driven by a power take off 4 of that gear box 5 belonging to existing motor 6 of the load vehicle 2.
• a control unit 7 is connected to the motor 6 of the load vehicle 2 for adjusting of its motor speed and hence that pressure which the high pressure compressor is delivering.
• Pressure sensors 8 are further used in order to sense and maintain predetermined working pressures.
• the control unit 7 comprises at least three function buttons 9, of which the first one is provided by an electric signal or radio signal with a predetermined frequency to start the load vehicle 2 and the high pressure compressor 3 in different steps or gradually by at least two depressions , whereupon the pressure sensors 8 in the form of a last-pressure sensor and a control pressure sensor in a way known per se are provided to sense the correct working pressure, of which function buttons 9 the second one is provided to shut off or unload the operation in steps and of which the third function button is provided by an electric signal or a predetermined radio frequency signal to give an impulse to the motor 6 for increasing the pressure or decreasing the pressure of the high pressure compressor 3 to manually determined values.
• the function buttons of the control unit 7 also can be distance controlled via a cable or predetermined radio frequency signals by a portable distance control unit, so that the second unit is adjustable in distance from the same i.e. from the first unit. Instead of using the function buttons in the control unit these can of course by replaced by icons belonging to a menu of a computer.
• the power take off 4 of the gear box 5 is via an universal joint 10 and belt pulleys 11 completed with driving belts 12 connected to the primary shaft 13 of the high pressure compressor 3 in order to bridge over a vertical height difference between the two.
• This height difference can be varied upwards to about 800 mm between the power take off 4 of the gear box 5 and the primary shaft 13 of the high pressure compressor 3, which is connectable by aid of a splined coupling or creep wedge coupling.
• the actual rotation speed of the primary shaft 13 of the high pressure compressor 3 is about 1100 - 1500 r/min and preferably about 1350 r/min during normal drilling by the first unit and the actual working pressure then amounts to maximum about 30 bar.
• the load vehicle 2 and the high pressure compressor 3 mounted on the same are integrated connected to each other at the same time as the load vehicle 2 having a loading space 14 after or just behind the high pressure compressor 3, which admits space for the first unit in one and the same equipage.
