Definitions

  • the invention relates to an electrical working device for the drill head or a similar part of a boring machine for tunnels, routes or the like which carries out a rotating working movement, namely a tunnel boring machine, the speed of the electrical drill head drive (one motor or in particular several mechanically for Parallel operation of coupled electric motors) is continuously adjustable.
  • Infinitely variable drives for tunnel boring machines or the like in their speed. are desired or required, among other things, to enable optimal adaptation to the mountain properties and gentle, low-vibration drilling operations.
  • this requirement could practically only be met by a hydrostatic drive.
  • Infinitely variable hydrostatic drives require a lot of space for the drive units and have a low overall efficiency.
  • the conceivable use of DC collector motors is opposed to considerable difficulties, such as their size and sensitivity to dust. Pole-changing three-phase motors are robust, but only allow a few speeds to be set in stages, so that continuous control is not possible.
  • the object of the invention is to provide a continuously adjustable or controlled electric rotary drive for tunneling machines, which can be accommodated well under the limited space and is characterized by favorable operating properties.
  • the invention also strives for an advantageous design of such a drive in detail. Further problems connected with the overall task, with which the invention is concerned, result from the respective explanation of the indicated solution.
  • the invention provides that the drill head drive contains at least one three-phase asynchronous motor, for the supply of which an inverter associated with the tunneling machine with control device is provided, by means of which the drill head drive is to be fed with current of variable frequency and which is in one the high degree of protection corresponding to the conditions of use.
  • the converter which is particularly splash-proof and dust-proof (e.g. protection class IP 65), is advantageously a so-called DC link converter with impressed current.
  • a DC voltage is converted into an AC voltage of the desired frequency and level.
  • An intermediate circuit choke provided for the converter operation is advantageously arranged separately from a control cabinet containing the converter. The latter is kept free from the heat generated in the DC link choke.
  • a heat exchanger is provided for removing heat from at least part of the device.
  • the heat exchanger is expediently designed as a water / air cooler. Air that is circulated within the unit is cooled by the colder water. The water can flow in a closed circuit and be cooled in the process .. If water is available at the place of use, this can also be done. be sucked in and drained again after passing through the heat exchanger.
  • the drill head drive or the motors of the same can be provided with direct-acting water cooling if self-cooling is not sufficient at low speeds.
  • the drill head drive can be switched over from converter operation to direct mains operation and vice versa. If there is a fault in the control electronics, on converter components or otherwise, then the operation of the machine can be maintained by supplying the motors directly from the mains. If the motors of the drill head drive are designed as pole-changing three-phase squirrel-cage motors, as provided in particular by the invention, then it is even possible to work with different speeds, which increases the availability of the system.
  • the drill head drive has several motors, as is expedient, these motors working in parallel are preferably supplied by a common converter in the busbar supply.
  • the motors can be mechanically coupled to one another in the usual way. This results in a problem-free load distribution between the drives.
  • the tunnel boring machine 1 shown in FIG. 1 has a machine body 2, also called an inner kelly, at the front end of which one with cutting rollers 4 or the like. equipped drill head 3 is rotatably mounted. This is operated by four three-phase asynchronous motors 5 working in parallel, in particular pole-changing motors, via a mechanical gear 6 and a shaft extending from it and running inside the machine body 2, which is shown in FIG. 2 is indicated at 7, driven.
  • the motors 5 are equipped with direct-acting water cooling.
  • the cooling circuits are indicated schematically at number 25.
  • the tunnel boring machine 1 also contains a bracing device 8, also called an outer cell, the two. Has groups of four clamping plates 9 which can be pressed against the wall of the opened tunnel. Like the bracing device, other parts of the tunnel boring machine, which are not explained in more detail here, can also be designed in the usual way.
  • a bracing device 8 also called an outer cell, the two.
  • Has groups of four clamping plates 9 which can be pressed against the wall of the opened tunnel.
  • other parts of the tunnel boring machine which are not explained in more detail here, can also be designed in the usual way.
  • One with the machine through tie rods 10 or the like. coupled trailer 11 has a steering position 12 and. then the parts and units for feeding the drive motors 5 shown in FIG. 2, as will be explained below.
  • Power supply is expedient, at 6 kV, 50 Hz.
  • This energy can be supplied from a station (not shown) to a supply transformer via a cable that can be wound on a drum the low voltage, which is supplied via a supply cable 13 to an encapsulated three-phase control cabinet 14, for example in protection class IP 54 or IP 65, can be, for example, 500 V or 380 V.
  • a circuit breaker 15 is provided in the entrance of the control cabinet a.14 for the entire subsequent part of the system.
  • a cable 16 leads to a switchgear cabinet 17, which is also adapted in form and degree of protection to the room and environmental conditions of tunnel construction, in particular is splashproof and dustproof. (eg IP 65), and which contains a converter and electronic control devices for supplying and controlling the drive motors 5.
  • IP 65 the control cabinet 17 is equipped with a heat exchanger in the form of a water / air cooler 18.
  • the water is constantly cooled or taken as cold fresh water from the environment and in turn cools the air when flowing through a coil system 19, or the like inside the cabinet 17 by a fan. is circulated.
  • One intended for conversion operations DC link choke 20 is installed as a separate unit in front of the control cabinet 17 and connected to it by a cable. It is advantageously designed as a cast resin throttle. Their heat is dissipated by convection.
  • the mode of operation of the converter for stepless speed adjustment of the three-phase motors is based on the principle of converting a DC voltage into an AC voltage of the desired frequency and level.
  • the DC voltage is in turn generated in the converter of the cabinet 17 from the AC voltage supplied by the control cabinet 14.
  • the converter works. as a DC link converter with impressed current.
  • a control panel 21 is provided in the control cabinet 17, from which cables 22 lead to the drive motors 5, which are supplied according to the principle of the busbar supply.
  • a cable 23 is also inserted into the control panel 21, which is led directly from a second output of the three-phase control cabinet 14.
  • the devices provided in the control panel 21 are designed such that the drive motors 5 can be fed either by the converter in the control cabinet 17 or directly from the three-phase network from the control cabinet.
  • the four drive motors 5 can be ramped up together with the "Start" command up to a speed set on a setpoint adjuster (not shown).
  • the drive speed can be set continuously from, for example, 1500 rpm to 150 rpm on this setpoint adjuster.
  • the maximum torque of the drill head 3 is limited by a current limitation in the converter. When this torque is reached, an acoustic and / or optical signal can be given by a device that is not reproduced. After this torque has been exceeded, the drive can be stopped automatically. After the machine has been withdrawn and the signal has been acknowledged, the drill head can be started again.
  • the second possible mode of operation of the device results when the changeover switches provided in the control panel 21 are switched to "mains operation". Then the motors 5 are supplied directly from the three-phase part in the control cabinet 14, in which the required contactors for this network operation are also located.
  • the Antri.ebs- motors 5 can be switched on one after the other. If the advantageous embodiment involves pole-changing motors, the desired speed can be preselected on a selector switch 24 on the control cabinet 14. The operating torque is displayed on an instrument.
  • This switchover option can in principle be useful and is particularly advantageous if a fault occurs in the converter part 17.
  • the operator of the machine is then immediately able to switch the supply of the drive motors 5 to mains operation by actuating the changeover switch in the control panel 21. No electrical intervention is required .. The machine is immediately ready for use again.
