    The boring direction of the mining machine is controlled at the section of drilling rod immediately behind the cutting head by inclination transducers (14), mounted at 90 degree intervals round the drilling rod. The control orientation of the rotating shaft (3) inside the outer casing of the drilling rod (9) by hydraulic actuators (10,11) moving the shaft, relative to the casing, round pivots (8). Hydraulic pressure is obtained from an eccentric (23) mounted on the shaft which operates a pump (23) to deliver pressurised hydraulic fluid to a storage chamber (20) before delivery to the hydraulic actuators (10,11) via magnetic control valves (16,17) controlled by the inclination transducers (14). The electric supply to these transducers and valves may be from a battery or from an electric generator mounted externally or internally to the drilling rod.

    专利说明:

    Deflecting means are installed on the outer pipe 3 for changing the direction of the well, made in the form of guide bars 5, which are actuated by regulating cylinders 6 installed in a sealed chamber 4 with the ability to interact with the ends of bars 5 closest to the rock-breaking tool.
    6c are connected with inclinometers 7 installed in the sealed chamber through solenoid valves 8 and 9.
    In order to avoid erroneous measurements, it is advisable to arrange inclinometers.
    7 crosswise. The bars 5 have a retainer 10 connecting the guide bars to the fixed pipe 3. The guide bars 5 have, on the side opposite to the placement of the control cylinders 6, limit stops 11 of the movements of the guide bars 5, and the stops 11 are spring-loaded with springs 12 for returning the guide bars 5 after their pressure has been relieved to the cylinders 6, an eccentric 13 is installed on the rotating inner pipe 1, which ensures the generation of working pressure for the hydraulic control of the guide bars through the cylinder ry 6. The sealed chamber 4 are arranged as a battery 14, a camera 15 with a fluid pressure generator 16. The electrical supply of the electric inclinometers 7 and the magnetic valves 8 and 9 is carried out either by means of a cable 17, used simultaneously as a logging and control, or by means of a generator 18 (Fig. 2) mounted on an external fixed pipe 3. A gear wheel is mounted on the generator shaft 19 20, which engages with the second gear wheel 21. This wheel is pressed into the inner rotary tube 1, which is a drilling shaft. In addition, this gear wheel 21 can be made in the drill shaft, i.e. in the inner rotary tube 1, so that the drill shaft itself will not experience the load from the additional forces. Terminals 22 are provided on the generator housing 18, by means of which the supply voltage is removed for the electric inclinometer 7 and solenoid valves 8 and 9. In addition, the generator can be made (Fig. 3} in the form of a stator 23, which forms a tubular sleeve, rigidly connected with an external fixed pipe 3, and a rotor 24 formed by permanent magnets, which are connected to a rotating pipe 1 with a power circuit.
    the voltage required for the inclinometer and the solenoid valves is removed from terminals 25.
    Device for drilling
    wells works as follows.
    During drilling, a remote control (not shown) located at the wellhead is transmitted to the well deviation information via cable 17 connected with inclinometers 7. After processing the data, appropriate commands are sent via cable 17 to drive the guide bars 5. The control and regulation is carried out periodically, it is advisable in the intervals between drilling, because during these periods, labor and other sources of error are excluded. However, measurement and adjustment can be carried out while drilling. The positioning of the guide bars is controlled by cylinders 6 using magnetic valves 8 and 9, which in turn are controlled by inclinometers 7. Due to the arrangement of the guides
    of the strip 5 on the pipe 1 first from the rock-cutting tool with the help of minimal movements of the cylinder 6 it is possible to carry out the necessary correction of the direction of drilling of the well.
