Definitions

  • the invention relates to a grinding machine, manually displaceable on a track, for grinding rails of a track, including a support frame which is designed to roll on the track via guide rollers and on which are arranged an energy module and a work module, wherein the work module comprises a pivotable grinding unit.
  • Various rail grinding machines are provided for removing imperfections on the rail, such as, for example, weld beads at rail joints, build-up welding, check rails, and burr formations on rail heads. Grinding machines of this kind are already well known from DE 20 2010 007 264 U1, DE 202 10 014 U1 and DE 202 10 021 U1.
  • this object is achieved by way of a grinding machine according to claim 1 .
  • the invention provides that the grinding unit comprises an electric motor and a grinding unit powered by the same, that the grinding unit is supported for pivoting about a longitudinal axis in a motor frame, and that the motor frame is arranged to be adjustable relative to the support frame. Due to this compact design and the flexible adjustability of the movably supported elements, it is possible to treat almost any point of the rail profile with high precision and efficiency.
  • the grinding unit is pivotable relative to the motor frame by at least 180°.
  • both sides of the rail profile can be treated in an advantageous way with one grinding unit in several work positions.
  • the electric motor is designed encapsulated.
  • the electric motor is protected from the grinding dust arising during working operations.
  • a further improvement of the device according to the invention provides that the grinding machine comprises a heat exchanger and a pump, and that the electric motor is designed having a liquid cooling system.
  • the liquid cooling system it is possible to dissipate a large quantity of heat in a technically simple manner and with low noise, and a consistent performance of the electric motor can be ensured.
  • the grinding machine comprises a compressor, and if the electric motor is designed having a compressed air cooling.
  • the electric motor can be designed in a compact way, and the cooling system is practically maintenance-free.
  • a simple embodiment of the invention provides that the electric motor is connected to the energy module via sliding contacts.
  • the sliding contacts guarantee a flexible energy transmission to the electric motor.
  • a further advantageous embodiment of the invention exists in that the electric motor is connected to the energy module via a flexible cable and a plug connection.
  • This flexible connection ensures a generous freedom of movement of the electric motor in working operations.
  • the energy module can be uncoupled without problem from the electric motor for transport.
  • a further improvement of the invention provides that the motor frame is supported for vertical adjustment in an intermediate frame, and that the intermediate frame is adjustable in the transverse direction relative to the support frame.
  • the motor frame is arranged to be pivotable about a vertical axis relative to the intermediate frame for free angular positioning of the grinding tool.
  • the grinding tool is placed upon the rail surface at a pre-defined angle, and the rail is machined precisely.
  • the intermediate frame is mounted on the support frame by means of manually detachable roller elements. With this, the intermediate frame is displaced almost friction-free relative to the support frame, and the intermediate frame including the grinding unit can be dismounted in a simple way from the support frame for easier transport.
  • a combustion engine/generator unit is arranged as energy module. With this, a continuous working operation independent of a power source is guaranteed.
  • the energy module comprises an electric energy store.
  • electric energy is intermediately stored for longer working operations of the grinding machine.
  • a serving combustion engine/generator unit can be switched off temporarily (for example, in tunnels) or entirely omitted.
  • a simple embodiment of the invention provides that the support frame is made up of parts, with an adjustable distance between the guide rollers associated with the one rail and the guide rollers associated with the other rail. With this, it is possible to adapt the grinding machine to any track gauge.
  • the energy module is connected to the support frame by means of manually detachable fastening elements.
  • the transport of the energy module separated from the support frame is thus considerably facilitated.
  • the invention combines several individual machines which were previously required. (Rail head grinding machine, rail web grinding machine, switch grinding—and deburring machine).
  • FIG. 1 side view of grinding machine
  • FIG. 2 top view of detail of free angular positioning
  • FIG. 3 detail view of motor frame with grinding unit
  • FIG. 4-7 working positions of grinding unit
  • the grinding machine 1 shown in FIG. 1 is a manually guided machine for treating rails 2 of a track 3 . It comprises a support frame 5 , designed to roll on the rails 2 via guide rollers 4 , at the ends of which an energy module 6 and a work module 7 are arranged.
  • the work module 7 comprises an intermediate frame 8 , a motor frame 9 and a grinding unit 10 .
  • the energy module 6 is arranged on the support frame 5 via quick-release fasteners 11 to be mechanically detachable.
  • the support frame 5 is designed in sections.
  • the grinding machine 1 is manually displaceable in a longitudinal direction 13 of the track.
  • the lever 15 is connected to the intermediate frame 8 by means of a linkage 17 .
  • Via a locking device 18 the intermediate frame 8 can be manually fixed to the support frame 5 .
  • a first hand wheel 19 By means of a first hand wheel 19 , the motor frame 9 mounted in the intermediate frame 8 can be adjusted together with the grinding unit 10 in a vertical direction 20 . Via a belt drive 22 , a second hand wheel 21 causes a rotary motion of the grinding unit 10 mounted in the motor frame 9 on a longitudinal axis 23 .
  • the rotary motion could be transmitted by a worm gear instead of the belt drive 22 .
  • FIG. 2 shows a top view of the grinding unit 10 including a free angular positioning device 24 .
  • the motor frame 9 including the grinding unit 10 is mounted in the intermediate frame 8 on a vertical axis 25 for pivoting about a free positioning angle ⁇ ⁇ ⁇
  • the required pivoting region, and thus the grinding unit 10 is adjusted relative to the rail 2 via two handles 26 and locked via clamping levers 27 .
  • FIG. 3 shows a detail view of the motor frame 9 including the grinding unit 10 .
  • the grinding unit 10 comprises an electric motor 28 and a grinding tool 29 .
  • the grinding tool 29 is shown as a dish grinding wheel and is exchanged for other grinding tools according to the particular application (cup grinding wheel).
  • the grinding tool 29 is connected directly to a rotor shaft of the electric motor 28 , resulting in a particularly compact design of the grinding unit 10 .
  • the electrical connection to the energy module 6 is provided via sliding contacts or a flexible cable.
  • FIGS. 4 to 7 show an excerpt of different working positions of the grinding unit 10 .
  • the grinding unit 10 is on a side facing the track center 30 .
