Definitions

  • the invention relates to a track-working rail processing machine for removing irregularities on a rail head surface of at least one rail of a laid track, with a machine frame supported on a front rail running gear viewed in a working direction and on a rear rail running gear and a tool frame for receiving at least one tool carrier.
  • Rail processing machines for processing a rail head surface are already known from various applications.
  • the defects present in the rail mirror are removed by a machining tool.
  • AT 513 035 B1 a device for grinding rails of a track, in which grindstones arranged one behind the other in the longitudinal direction of the rail and each associated with a rail are provided, each grindstone being deliverable by means of a drive in the vertical direction or to a rail running surface.
  • a processing machine is known in which a tool carrier is articulated to a machine frame via a hydraulic piston-cylinder unit.
  • the object of the present invention is to provide a device of the type mentioned at the outset, with which an exact adaptation of the machining tools to the track geometry and an inexpensive and economical rail machining is possible.
  • this object is achieved in that the machine frame is supported on a front rail undercarriage viewed in the working direction and on a rear rail undercarriage and in that the tool frame is articulated with a rear end on the rear rail undercarriage on a vertical axis of rotation in a pivot point and with a front end a separate rail undercarriage located between the front and rear rail undercarriages is supported.
  • This training ensures that the tool frame and thus the machining tool are adapted to the track geometry independently of the machine frame. This results in a high surface quality of the rails with a resulting noise reduction when driving on them.
  • a sensible development provides that the rear rail carriage is designed as a bogie and that the machine frame is supported on the bogie so that it can rotate about the vertical axis of rotation.
  • the own rail chassis of the tool frame is designed as a supported bogie. It is advantageous if support elements can be activated for a work trip by means of a control in the respective supported bogie. It is then possible to switch off the respective support during a transfer run in order to improve the driving properties of the rail processing machine.
  • a swiveling chip collector located above the tool frame is arranged on the machine frame. It is possible to collect the chips removed from the rail surface in a closed manner so that they can then be unloaded in a targeted and environmentally friendly manner onto a designated unloading area or a loading area of a truck or transport wagon next to the track.
  • Another embodiment of the invention provides that a machining tool located on the tool carrier has a floating bearing. In combination with the support of the rear and the own rail chassis, this results in an independent adaptation of the tool holder to both rails.
  • a sensible embodiment is realized in that a machining tool located on the tool carrier is designed as a milling tool. As a result, high material removal can be achieved, for example, in the event of grooves.
  • a further design ensures that a machining tool located on the tool carrier is designed as a grinding tool.
  • a particularly high surface quality of the rail head can be achieved in this way.
  • a further advantage is given when the machining tool is designed to be pivotable from a transport position into a working position. This considerably facilitates the mobility during transfer rides.
  • the respective processing tool is equipped with its own drive. This means that no central drive of the machine is required and the machining tool can be operated independently.
  • the machine is designed as a traction vehicle with its own engine. As a result, no additional traction vehicle would be necessary for the mobility on the track.
  • the machine 1 shown on a track 2 for removing irregularities on a rail head surface 3 comprises a machine frame 7 supported on a front rail carriage 5 viewed in the working direction 4 and a rear rail carriage 6.
  • a tool frame 8 is at a rear end 9 above the rear rail carriage 6 on a vertical axis of rotation 10 in a pivot point 11 is articulated and supported with a front end 12 on a separate rail undercarriage 13 located between the front 5 and the rear rail undercarriage 6.
  • the rear rail carriage 6 and the own rail carriage 13 are designed as a supported bogie.
  • Arranged on the tool frame 8 are two tool carriers 14 which can be pivoted from a transport position into a working position, together with machining tools 15 with a floating bearing 16.
  • a chip collector 19 which can be pivoted about an axis, is arranged between the machine frame 7 and the tool frame 8. For emptying, the chip collector 19 is raised by means of a lifting arm and pivoted laterally about the axis.
  • Fig. 1 shows a working position shown in full line and a transport position of the tool carrier 14 and machining tools 15 shown in dashed line. Each machining tool can advantageously be acted upon by its own drive 38.
  • a supply device 39 for supplying the drives 38 of the machining tools 15 is provided below the machine frame 7. This is, for example, an internal combustion engine that drives hydraulic pumps of a hydraulic system or a generator via a transmission.
  • the respective supported bogie comprises a bogie frame 20 and rail wheels 22 arranged on two wheel axles 21.
  • Two springs 24 are positioned between the bogie frame 20 and a spring plate 23 arranged on each side below the respective wheel axle 21.
  • a hydraulic cylinder 25 per wheel suspension and a second cylinder 26 without hydraulics are arranged on the associated spring plate 23 or axle bearing as supporting elements on the bogie frame 20.
  • a second piston 31 is arranged in the second cylinder 26 and is connected to the first piston 28 by a piston rod 32.
  • Fig. 2 the bogie is in the relaxed state and is therefore not pressurized via the hydraulic line 30.
  • the first piston 28 is in the lowered state and the springs 24 are therefore not preloaded. The support of the respective bogie is thus deactivated.
  • Fig. 3 an activated support is shown.
  • the hydraulic cylinder 25 is pressurized via the hydraulic line 30 so that the first piston 28 is pressed upward.
  • the second piston 31 connected to the first piston 28 via the piston rod 32 is forcibly moved in the direction of the hydraulic cylinder 25 and prestresses the springs 24.
  • the bias of the springs 24 results in a more stable support and thus a more precise machining of the rail head surface 3.
  • Fig. 4 and Fig. 5 the storage in the articulation point 11 is shown.
  • the rear end 9 of the tool frame 8 is articulated on a guide pin 34 located on a vertical axis of rotation 10.
  • the guide pin 34 is locked in the machine frame 7 and has a conical recess 36 at its upper end 35, which serves as a stop for the tool frame 8.
  • Bearing shells 37 with spherical outer surfaces with the articulation point 11 as a common center point are arranged around the guide pin 34.
  • Bearing shells 40 with corresponding spherical inner surfaces are arranged in the tool frame 8, so that free tilting and rotating movements of the tool frame 8 around the articulation point 11 are possible.
  • Fig. 5 the freedom of movement of the tool frame 8 relative to the machine frame 7 is shown in a horizontal plane. So that can the machining tools 15 follow the rails 18 even in tight curve radii.
