Definitions

  • the invention relates to a grinding machine, which can be manually moved on a track, for grinding rails of a track, with a support frame that can roll on the rails via guide rollers and on which an energy module and a work module are arranged, the work module comprising a pivotable grinding unit and the grinding unit having an electric motor and a grinding tool driven therewith.
  • Various rail grinding machines are designed to remove unevenness on the rail, such as those caused by weld beads on rail joints, build-up welds, wheel guides and burrs on rail heads. Such grinding machines are already several times from the DE 20 2016 005841 U1 , of the DE 20 2010 007 264 U1 , of the DE 202 10 014 U1 , of the DE 1 023 360 and the DE 202 10 021 U1 known.
  • the invention is based on the object of specifying an improvement over the prior art for a grinding machine of the type mentioned at the beginning.
  • this object is achieved by a grinding machine according to claim 1.
  • the invention provides that the grinding unit is mounted pivotably about a longitudinal axis running in the longitudinal direction of the track in a motor frame and that the motor frame is arranged so as to be adjustable with respect to the support frame. Thanks to this compact design and the flexible adjustability of the Movably mounted elements, almost every point of the rail profile can be machined with a high degree of accuracy and efficiency.
  • the grinding unit can be pivoted by at least 180 ° with respect to the motor frame.
  • both sides of the rail profile can advantageously be processed in several working positions with one grinding unit.
  • the electric motor is encapsulated. This protects the electric motor from the grinding dust generated during work.
  • 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 with liquid cooling. Thanks to the liquid cooling, a large amount of heat can be dissipated evenly and in a technically simple manner and with little noise and a constant output of the electric motor can be guaranteed.
  • the grinding machine includes a compressor and if the electric motor is designed with compressed air cooling.
  • the electric motor can have a compact design and the cooling system is almost 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 ensure a flexible transfer of energy to the electric motor.
  • a further advantageous embodiment of the invention is given by the fact that the electric motor is connected to the energy module via a flexible cable and a plug connection.
  • This flexible connection ensures that the electric motor can move freely during work.
  • the power module can be easily disconnected from the electric motor for transport via the plug connection.
  • a further improvement of the invention provides that the motor frame is mounted so that it is height-adjustable in an intermediate frame and that the intermediate frame can be adjusted in the transverse direction with respect to the support frame. This guarantees even greater freedom of movement for the grinding unit and the resulting more flexible use of work in order to machine the rail precisely.
  • the motor frame is arranged so that it can pivot about a vertical axis in relation to the intermediate frame in order to release the angle of the grinding tool.
  • the grinding tool is placed on the rail surface at a specified angle and the rail is precisely machined.
  • the intermediate frame is mounted on the support frame by means of manually releasable roller elements.
  • the intermediate frame is displaced with almost no friction relative to the support frame and the intermediate frame and the grinding unit can be easily removed from the support frame for easier transport.
  • an internal combustion engine / generator unit is arranged as the energy module. This guarantees continuous work regardless of a power source.
  • the energy module comprises an electrical energy store.
  • electrical energy is temporarily stored for longer use of the grinding machine. If the accumulator is sufficiently dimensioned, a supplying combustion engine / generator unit can be switched off in the meantime (e.g. in a tunnel) or it can be omitted entirely.
  • a simple embodiment of the invention provides that the support frame is designed to be divided with an adjustable distance between the guide rollers assigned to one rail and the guide rollers assigned to the other rail. This makes it possible to adapt the grinding machine to any track gauge.
  • the invention essentially combines several individual machines that were previously necessary. (Rail head grinding machine, rail web grinding machine, turnout grinding and deburring machine)
  • the illustrated grinding machine 1 is a manually guided machine for processing rails 2 of a track 3.
  • This comprises a support frame 5 which can be rolled on the rails 2 via guide rollers 4 and on which an energy module 6 and a work module 7 are arranged at each end.
  • 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 in a mechanically detachable manner via quick-release fasteners 11.
  • the support frame 5 is designed to be divided for a track width regulation.
  • the grinding machine 1 can be manually displaced in a longitudinal direction 13 of the track by means of a handle 12.
  • the lever 15 is connected to the intermediate frame 8 via a linkage 17.
  • the intermediate frame 8 can be manually fixed on the support frame 5 via a locking device 18.
  • the motor frame 9 mounted in the intermediate frame 8 together with the grinding unit 10 can be adjusted in a vertical direction 20 via a first handwheel 19.
  • a second handwheel 21 provides a rotary movement of the grinding unit 10 mounted on a longitudinal axis 23 in the motor frame 9 via a belt drive 22.
  • the rotary movement 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 the angle release device 24.
  • the motor frame 9 including the grinding unit 10 is mounted on a vertical axis 25 in the intermediate frame 8 such that it can be pivoted about a release angle ⁇ .
  • the required swivel range and thus the grinding unit 10 with respect to the rail 2 is set by means of two handles 26 and is locked by means of clamping levers 27.
  • Fig. 3 shows a detailed 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 disk grinding wheel and is replaced by other grinding tools depending on the application. (Cup grinding wheel)
  • the grinding tool 29 is connected directly to a rotor shaft of the electric motor 28, which results in a particularly compact design of the grinding unit 10. In this way it is possible to pivot the grinding unit 10 by at least 180 ° about the longitudinal axis 23 and thus to ensure the flexible application possibilities.
  • the electrical connection to the energy module 6 is made via sliding contacts or a flexible cable.
  • Fig. 4-7 show an extract of various working positions of the grinding unit 10.
  • the grinding unit 10 is on a side facing the track center 30.
  • the grinding unit 10 is in the starting position, is aligned horizontally and processes an inside of a rail head 31 Fig. 5 an outside of the rail head 31 is machined.
  • the grinding unit 10 is raised via the first handwheel 19, moved with the lever 15 and then lowered again.
  • Fig. 6 Fig. 8 shows how to machine an inner rail web 32 over the second Handwheel 21 90 ° rotated grinding unit 10.
  • the outer rail web 32 is machined.
