Definitions

  • the invention relates to a track construction device for processing grooved rails.
  • grooved rails having proven particularly useful in inner-city tram traffic.
  • Grooved rails are generally provided with corresponding water tanks at larger intervals, which collect the water entering in the area of the groove and feed it into the sewer system.
  • it has hitherto been customary either to drill holes in the bottom of the grooved rail using a drill or to burn corresponding slots in the groove using a welding torch.
  • a lift-off superstructure device for machining base plates for rails by milling with the superstructure ready for driving which has a milling device which is mounted on a frame to be placed on both sides of the rail so that it is longitudinally and vertically displaceable, the milling device being equipped with two milling disks which are mounted in such a way that they can mill material out of the fastening means holding them on both sides of the rail.
  • the EP 2808446 A1 shows a device for machining a track.
  • a tool bed is provided to which a free-form milling system accommodating at least one machining tool and at least two clamping arms that encompass a machining area are assigned, the clamping arms carrying clamping jaws which are provided with a clamping device for securing the tool bed on a track.
  • Such devices are only placed on a single rail, so that it is difficult to relocate the device. As soon as the processing point is not accessible from the side, a road-rail excavator would have to be used or another lifting device can be used, which significantly increases the complexity of the machining.
  • a chassis for rail machining which consists of a wheel arrangement that rolls on the rail head, with grinding or milling machines attacking the rail head from the chassis.
  • the running gear has a main frame on which bogies are arranged on upper and lower pivot bearings at a mutual distance from guide trolleys with main support rollers and lateral guide rollers and, starting from the main bogies on pull-out trolleys, rollers are arranged opposite the guide trolleys in a roller arrangement.
  • FR-A-2783446 discloses a track construction device for processing grooved rails, with a processing unit which can be fixed to the grooved rail via a retaining clamp, the processing unit having a base body, with respect to which a milling device can be displaced in three mutually perpendicular spatial directions, so that a cutting device can be machined by means of a milling head of the milling device Machining of the grooved rail for milling an elongated hole in the bottom of the grooved rail can be carried out.
  • a track construction device for processing grooved rails which has a frame which is provided with a first pair of wheels which can be arranged along a first grooved rail and a second pair of wheels which can be arranged along a second grooved rail, with one between the first pair of wheels Machining unit is fastened adjustable relative to the first grooved rail via swivel arms on the frame so that it can be brought down onto the grooved rail, and can be fixed to the first grooved rail via holding clamps arranged on the machining unit, the machining unit having a base body, with respect to which a milling device in three to each other perpendicular spatial directions is displaceable, so that by means of a milling head of the milling device, machining of the rail, in particular milling of an elongated hole in the bottom of the grooved rail, can be carried out.
  • the solution according to the invention is characterized in that the track construction device is designed to be movable on the rails by means of the pairs of wheels. Accordingly, the position at which the milling head of the milling device can perform machining of the rail can be freely selected by shifting on the rails.
  • the track construction device can therefore typically be moved by the operator without external aids, so that a large number of processing points that are arranged at a certain distance from one another can also be processed. In particular, when milling elongated holes in the bottom of grooved rails, such processing points will be present at distances from one another, only at predetermined positions water tanks are arranged below the grooved rail.
  • the processing unit can by means of the holding clamps be set on the first rail, so that the position can be selected exactly by moving the milling head, for example above the water tank.
  • the processing unit must be displaceable in all three spatial directions, so that the milling head then typically has to be displaced in only one direction from a starting point to an end point in the longitudinal direction of the first rail to form the elongated hole, with the milling head moving lower after the end point has been reached can be effected.
  • precise machining of the rail is thus possible.
  • a suitable choice of milling head also enables hardened rails to be machined.
  • the milling device can be provided with an optionally exchangeable end mill, so that machining can be carried out on the bottom of a grooved rail or in a center piece of a switch.
  • the axial length of the end mill can be selected so that the machining point on the bottom of the grooved rail or in the heart of the switch is reached without the milling head touching down on the top of the rail.
  • z. B. milling out cracks at the heart of points is possible.
  • the frame is designed in two parts with a first sub-frame and a second sub-frame, so that the first pair of wheels can be offset against the second pair of wheels perpendicular to a direction of travel.
  • the second sub-frame can be inserted into the first sub-frame transversely to the longitudinal direction.
  • the distance between the first pair of wheels and the second pair of wheels can be varied, so that the track construction device can be used variably for different track widths.
  • the second sub-frame into the first sub-frame, for example by means of telescopic insertion frame segments with different dimensions, an adjustment can now be made when machining rails in standard, meter or broad gauge.
  • cutouts can be provided at discrete positions on the second subframe, for example, which can be brought into overlap with corresponding cutouts on the first subframe, so that the desired standardized track width can be set by means of a guide bolt or the like.
  • the track width can also be continuously adjustable.
  • the first sub-frame comprises the first pair of wheels and an articulated receptacle for the pivot arms.
  • a platform can be formed over the first sub-frame.
  • This procedure makes it possible to carry out the adjustability of the track width described above in such a way that, on the one hand, the orientation of the processing unit relative to the first rail is maintained and, on the other hand, any objects above the wheels that may be arranged on a platform are not affected by the track change with regard to their position . In this way, a lane change can be carried out relatively easily without individual components of the device having to be realigned.
  • a storage container is arranged on the frame, via which a cooling fluid, in particular water, can be fed to the milling head.
  • the milling head is cooled by means of the cooling fluid, so that the service life of the milling cutter is significantly increased compared to uncooled use.
  • the cooling fluid can be set up accordingly via a Reservoirs are only fed by the influence of gravity, but also by means of a pump specially designed for this purpose.
  • the amount of cooling fluid supplied can be adjusted by means of a suitable throttling, for example by means of a valve or some other cross-section-changing device.
  • the storage container is advantageously arranged on the platform, but can also be connected directly to the frame.
  • a power unit is arranged on the frame, which enables an electrical supply to at least the milling device.
  • the power unit equipped, for example, with an internal combustion engine makes it possible to create a power supply at least for the milling device independently of a mains connection.
  • Other electrical consumers for example a lighting device for night construction sites or other processing devices, can of course also be operated via the power unit.
  • the generator set is in turn advantageously arranged on the platform, but a direct connection to the frame is also possible.
  • the holding clamps are designed to be magnetic.
  • the holding clamps can be designed to be adjustable with respect to their position in relation to the frame.
  • Magnetic retaining clips enable the machining unit to be reliably fixed with respect to the first rail.
  • the movement in the three spatial directions can be carried out by means of mechanical spindle drives.
  • both the advancement of the milling head and the positioning of the milling head relative to the first rail can be carried out by means of spindle drives, so that no complex controls are necessary, as would be required, for example, by means of adjustability by servomotors.
  • This procedure also enables intuitive operation by a user.
  • the first pair of wheels and / or the second pair of wheels have a profiled design on their running surfaces.
  • a first embodiment of a track construction device 2 is shown below.
  • the track construction device 2 comprises a frame 4, on the underside of which a first pair of wheels 6 is arranged.

  • the frame 4 can be designed on its upper side with a platform 10 so that further objects can be placed on the track construction device 2. Contrary to the representation in Fig. 1 the platform 10 can also completely cover the frame 4.
  • the track construction device 2 also has a processing unit 12 which is connected to the frame 4 via pivot arms 14.
  • the machining unit 12 comprises a milling device 16, the milling head 18 of which is designed, for example, in the form of an end mill.
  • the machining unit 12 can be pivoted relative to the frame 4 via the pivot arms 14, so that after the machining unit 12 has been lowered Contact between an upper side of the first rail 8 and retaining clips 20 occurs.
  • the holding clamps 20 thus serve to fix the machining unit 12 on the upper side of the first rail 8.
  • the machining unit 12 can now be moved in all three spatial directions with respect to the first rail so that, for example, an elongated hole can be milled in the bottom of the grooved rail 8 using the milling head 18.
  • the milling device 16 is typically driven by means of an electric motor, a power unit 22 which can supply the milling device 16 with electrical energy is preferably arranged here on the track construction device 2.
