Definitions

  • the present invention relates to an installation of reprofiling of railroad tracks working in way.
  • Track rails not only have profiles damaged but still longitudinal undulations whose amplitudes vary.
  • Patent CH 680,672 describes a process allowing optimal programming of the reprofiling operations to be carried out on a section given. Thanks to this process it is possible to optimize the maintenance operations in order to reduce time lane occupation.
  • German patent DE 32 22 208 is serves as two height-adjustable pads that form a symmetrical base on either side of the cutter.
  • the patent FR-2 405 329 uses as support for grinding wheels frames hinged to each other along perpendicular axes to the longitudinal axis of the track. These frames rest on the rail by skates of identical lengths. The grinding bases can be of different lengths. These devices have the disadvantage of being able to correct only one type of defect of the rail at a time.
  • the longitudinal undulations of not all rails have the same wavelength, both long ripples (30 cm to 3 meters) and short undulations (3cm to 30 cm).
  • Existing devices have tools carried by a single guide base and therefore only correct undulations of a certain wavelength (long with a long guide base) which is not compatible with the quality required for high speed networks.
  • the object of the present invention is to obviate the drawbacks cited above.
  • the licensee proposes that effect a reprofiling installation of at least one rail a railway capable of removing a large amount of metal and eliminate both long ripples and short waves, while ensuring a perfect finish reprofiled rails.
  • Another object of the invention is increase the speed of the rail reprofiling work.
  • the reprofiling installation must allow to remove and treat the resulting metal residue reprofiling in progress.
  • the subject of the present invention is an installation reprofiling on the surface of the fungus at minus one rail of a railway which is distinguished by the Features listed in claim 1.

  • Figure 14 shows the device allowing the chip discharge.
  • the shaving milling and storage wagon illustrated in Figure 1 is the top element of the installation rail reprofiling.
  • This wagon features, located at the front of the milling device, a device of measurement 1 which makes it possible to evaluate the deformations of the rail treat.
  • the milling device is fixed to the chassis 2 of the rail vehicle 3 using cylinders 4,5,6 which keep the milling device in position work and take it up.
  • a drawbar 7 connects the frame 2 to frame 9 of the milling device. This drawbar 7 allows training along the path of the device milling.
  • the milling device has two frames 8.9 articulated between them. These 8.9 frames rest in three points on each rail through units of support and guide 10,11,12 of different lengths.
  • Frames 8 and 9 have a different length, frame 8 bearing the milling unit 13 being longer than the frame 9 which carries the milling unit 14.
  • These frames 8.9 each constitute a guiding base for the unit of milling 13,14 they carry. Milling unit 13 mounted by the longest frame 8 will eliminate the long undulations of the rail, while the milling unit 14 carried by the frame 9 will eliminate the ripples short.
  • each of the milling units 13,14 is provided with a cutter as well as means for moving this cutter which will be described in detail below.
  • each milling unit is pivoted on its support around a horizontal axis, for example as described with reference to Figures 4 and 5.
  • Figure 1 further illustrates devices rail heating 15,16 located at the front of each two milling units 13,14 as well as a device cooling of the rail 17 located at the rear of the milling device. Heating devices from rail are mounted on the frames 8.9 respectively. Unity cooling 17 is towed by the second frame 9 using a drawbar.
  • the measurement unit 1 of the rail deformations allows determine the depth of cut you want work the strawberries, as well as the power to provide heating units for forward speed given.
  • FIG. 2 illustrates schematically and in more detail an embodiment of the milling device.
  • This device comprises a first frame 8 connected via two cylinders 4,5 to chassis 2 of the vehicle. These 4.5 cylinders hold the frame 8 under the frame 2 and allow to raise it when walking high foot for example. In operation, these cylinders 4.5 allow press the milling unit against the rail with a determined force.
  • the frame 8 seen from the side has a horizontal part extending approximately between the two cylinders 4 and 5. This horizontal part is extended by an amount oblique towards the front and vertical at the back.
  • the amount oblique is connected to a first support device and guide 10.
  • This device 10 is provided with rollers 18 which are in contact with the rail in the working position and guide shoes 19.
  • a second support and guide 11 serves as a support for the rear upright of the frame 8.
  • the milling device also has a second frame 9 carrying a second milling unit.
  • the amount before oblique of the second frame 9 is articulated on the upright rear of frame 8 by means of an axis 20 perpendicular to the longitudinal axis of the rail.
  • the rear upright of the frame 9 rests on a support and guide device 12 also fitted with castors and guide shoes. Both 8.9 hinged frames rest at three points on rails.
  • Two guide columns 21,21 'integral with the part frame 8 extend perpendicularly to the latter towards the rail.
  • a support 22 provided two bores corresponding to the guide columns 21.21 'is connected via a screw 23 to the frame 8.
  • This support 22 includes a cutter 24 as well as the motor used for his training.
  • a second milling unit is arranged in the same way under the frame 9.
  • Figure 3 which is an end view of the device milling shows the device for adjusting the spacing 8.9 frames associated with each rail.
  • a hydraulic cylinder 26 coupled to a guide device 27 allows to press the guide pads 19 against the inner flank of each rail. These pads 19 can be replaced by guide rollers bearing against the side inside the rail.
  • the guide device is still provided with a guide roller 28 which is applied under the action of a jack 29 against the outer flank of the rail thereby ensuring perfect transverse guidance.
  • the support and guiding devices 10,11,12 comprise several 18 wheels and skates 19. The 18 wheels can in a variant be replaced by support pads. These rollers 18 and their pads 19 can be spaced each other of a fixed value or according to a function determined.
  • the first strawberry will be able to correct the longest ripples then that the second cutter 24 'carried and guided by a base 9 shorter corrects shorter ripples.
  • the distance between the two strawberries is determined to ensure the best transfer function of the whole, i.e. the best correction for long ripples and short of the rail. We thus obtain not only a very sharp decrease in the amplitude of the defects, but also excellent surface quality thanks to the fact that the second 24 'cutter works at a cutting depth practically constant, the significant defects having been eliminated by the first cutter 24.
  • FIG 2 again schematically illustrates a unit heater 31 mounted on chassis 22.
  • This unit heating 31 makes it possible to bring the surface film of the rail head at a temperature of around a few hundred degrees, which greatly facilitates the work of strawberries 24.24 '.
  • Working temperature is suitable for each type of rail steel. Heating is usually achieved through a heater by HF induction, but we can also consider a laser heater or other device allowing to quickly bring the surface layer of the rail at a high temperature.
  • a second unit of heating (not shown) can be arranged on the support 22 'from the second cutter 24'.
  • Rail heating allows on the one hand to increase productivity (speed of advancement and material removal) from milling by a factor of the order of 5 and on the other hand the wear of the cutters is reduced by a factor of the same order of magnitude.
  • a suction device that collects the chips produced by strawberries. The suction device and chip storage is described with reference to Figure 13.

  • This connecting element 45 is pivotally mounted on the support 44 along an axis contained in a vertical plane passing through an axis parallel to the longitudinal axis of the rail.
  • Means (not shown) are arranged in the support 44 allowing the position to be varied angle of the connecting element 45 relative to the support 44 under the action of a control member.
  • the frame 8 which serves as a guide base for the milling unit comprises a part 46 provided with a mechanical stop 47.
