- the fact that the energy is generated in the area of the boring machine on the drill head side the disruptive supply cables and hoses from the rear end of the protective tube omitted.
- the gear instead of the gear, other devices can of course also be used, which are able to transmit a rotary motion.
- a bar or is in the outer area of the screw conveyor.
- a gear rim or the like Arranged, the inner diameter of which is larger than that Outside diameter of the screw conveyor, and which ring gear or the like.
- the gear wheel or the like is drivable. This represents an easy implementation the drill head-side power generation. that the bar on the outside of the Conveyor screw is arranged, the crushing of the ground or the like is not significantly hindered.
- Inserting the screw conveyor into the Protection tube can be further facilitated if the or each ledge faces outwards tapering cross section and possibly the driver of the ring gear or the like one after has a tapering cross-section on the inside. This ensures that when the Screw conveyor in the protective tube does not collide with the bar, but rather automatically pushes it into the correct position.
- Another embodiment variant is formed in that a connected drum is arranged, and that the drum one towards Has axis of rotation of the screw conveyor facing recess, and that around A worm gear or the like is arranged, the inner diameter of which is greater than is the outside diameter of the screw conveyor, and the one in the recess of the Drum-projecting driver is connected, which when the screw conveyor rotates is taken along, and that the gear or the like can be driven via the ring gear or the like.
- the use of a cylindrical drum has stability advantages over a bar.
- a toothed ring or the like can also be connected to the screw conveyor, and via the Sprocket or the like.
- the gear or the like are driven to generate energy.
- an alternator is provided by the gearwheel or the like to generate electrical energy to supply the measuring and / or control devices drivable in the area of the drill head.
- electrical or electronic devices supplied with energy and their Function are guaranteed. These devices include e.g. the facilities for Detection of a deviation from the ruffled drilling direction.
- a gear or the like Hydraulic pump for generating pressure to supply the measuring and / or Control devices in the area of the drill head.
- a hydraulic unit, drivable e.g. a hydraulic unit, drivable.
- the hydraulic cylinders are used to adjust the cutting shoe driven. which compensates for any deviation from the target drilling direction becomes.
- a receiver for the is advantageously in the protective tube in the area of the drill head wireless reception of control signals provided. Any controls from outside without cables.
- a radio signal receiver conventional remote controls using suitable carrier frequencies Control of the drill head can be used.
- the receiver can be an optical one Be a receiver and control signals using modulated laser light or infrared light receive.
- the optical receiver has the advantage over the radio signal receiver that there is no interference from electromagnetic fields. For that is one such receivers more susceptible to pollution.
- a transmitter for the wireless transmission of Signals can various measured values or the like recorded in the drill head in the Control center are transferred, on the basis of which tax measures are taken can.
- the transmitter can be a radio signal transmitter or be an optical transmitter.
- the tunneling machine shown in Fig. 1 consists of a protective tube 6 in which the the auger 2 connected to the drill head 1 is rotatably arranged.
- a protective tube 6 With the front End of the protective tube 6 is a cutting shoe 3 via a bearing 5, which is an adjustment of the cutting shoe 3 in any direction. connected.
- the cutting shoe 3 is preferably hydraulically adjustable. to deviations from the desired To be able to compensate the direction of advance.
- At least two are used for adjustment Hydraulic cylinder 4. which pivot the cutting shoe 3 relative to the bearing 5. This Swiveling is carried out according to the deviation from the target direction. With help of the boring head 1, the rock or soil in front of it is broken up or crushed and on the rotating screw 2 against the direction of advance to transported back end of the protective tube 6.
- the Ledge 7 a driver 8 which is connected to a ring gear 9.
- the ring gear 9 in turn, a gear 10 drives.
- the gear 10 are located above the Screw conveyor 2 from pollution and. Protected the facilities for generating the energy required in the tunneling machine. With the help of an alternator 11 is off the rotation of the gear 10 generates electrical energy, which for various measuring and Control devices is necessary.
- a hydraulic pump is connected via a planetary gear 12 13 generated to generate the pressure for driving the hydraulic cylinder 4.
