Definitions

  • the present invention relates to a device for applying lubricant to a railway track.
  • the invention also relates to a railway track lubrication system and to a method for lubricating a railway track.
  • the noise caused by a railway traffic emanates from a number of different sound sources.
  • the wheel-rail system for instance causes dynamic forces which produce low-frequency vibrations and high-frequency sound.
  • the noise transmitted through the air consists mainly of motor noise (noise caused by the motor of the locomotive), rolling noise (the noise caused by rolling of the wheels over the rails), curve squeal noise (the noise occurring in the bends in the rail) and braking noise (noise as a result of braking). Aerodynamic noise can furthermore be a factor at very high speeds.
  • Curve squeal noise occurs at the position where the rails define a curved path, such as in a bend or at a points. Excessive curve squeal noise generally occurs in curves with a radius of less than 500 metres. This curve squeal noise is the result of the difference in rotation speed of the inner wheel and the rotation speed of the outer wheel in such a curved path. A further adverse effect is wear of the rails and of the wheels of the railway vehicle. In order to reduce the curve squeal noise caused by a passing rail vehicle, stationary rail track lubrication systems are known with which the friction between the outer rail wheel and the outer leg (i.e. the rail on the outer side of the curve) can be reduced, wherein the traction and the braking power are practically not adversely affected. As a result the lifespan of the rail is prolonged and the noise emission of the passing rail vehicle is reduced.
  • a known stationary rail track lubrication system there is arranged along the rail an elongate plate in which various grease openings are present.
  • the lubricant is applied to the side of the outer rail (outer leg) as a rail vehicle approaches.
  • the known system dispenses an inaccurate quantity of lubricant.
  • too little lubricant is applied the system does not operate satisfactorily and the high noise emissions are not reduced, or hardly so.
  • too much lubricant is applied, this can result in an increase in the braking distance and a reduced traction.
  • This also means that either large supplies of lubricant must be available, or that the supplies of lubricant must be replenished at relatively short intervals.
  • a lubrication system which is provided with a number of stationary nozzles with which lubricants can be sprayed onto a rail.
  • the known system has a vibration sensor on the basis of which the approach of a train is detected.
  • the nozzles spray a first type of lubricant against the side of the rail and a second type of lubricant, with a composition differing from that of the first type, onto the top side of the rail.
  • the first lubricant is sprayed against the side of an outer rail (outer leg) to protect the rail from wear resulting from the wheel flanges of the locomotive, while the second lubricant is sprayed onto the rail after the locomotive has passed in order to reduce wear caused by the wheels of the carriages.
  • the known system however provides an insufficient degree of reduction in the curve squeal noise caused by a passing train.
  • a device for applying lubricant to a curved part of a railway track comprising:
  • the spray head of the device comprises several nozzles, for instance two or more nozzles, for spraying the lubricant in different (two) directions to different locations on the upper surface (tread) of the rail. It has been found that exceptionally good results are produced when four nozzles are used to spray the lubricant in four different directions.
  • Four "droplets" of lubricant hereby come to lie at exactly the correct position on the rail.
  • the lubricant is here preferably applied in the middle of the tread.
  • the device comprises a piston which is drivable with an electric motor.
  • the housing is however provided with a fluid feed opening for feeling a fluid with which the piston is drivable.
  • the fluid can be a liquid but is preferably a gas, such as nitrogen gas stored in a standard nitrogen bottle.
  • the device preferably comprises a fluid reservoir in which the fluid is stored under overpressure. The fluid is under a high pressure such that the piston is thereby driven in the spraying agent housing. This latter construction is extremely simple and little susceptible to malfunction.
  • the device comprises a housing in which the spray head is arranged, wherein the housing is provided with height adjustment means for varying the height of the spray head relative to the rail.
  • the height adjustment means enable a correct positioning of the spray head relative to the rail, so that the lubricant comes to lie exactly at the correct locations on the upper surface of the rail.
  • the device comprises a housing in which a vibration sensor is disposed.
  • the housing can herein be coupled rigidly in direct or indirect manner to the relevant rail so that vibrations in the rail are transmitted via the coupling and the housing to the vibration sensor.
  • the vibration sensor therefore remains protected by the housing, which enhances the robustness of the device.
  • the device comprises a spraying agent reservoir arranged exchangeably in the housing in order to simplify maintenance of the device.
  • a spraying agent reservoir arranged exchangeably in the housing in order to simplify maintenance of the device.
  • the device comprises a temperature sensor which is connected to the control means and which generates a temperature signal representative of the ambient temperature, wherein the control means are adapted to lubricate the rail only at a temperature above a pre-stored minimum temperature. At lower temperatures it is advisable not to apply any lubrication. When for instance the rail is covered with snow or in the case of ice, lubricant in many cases does not remain lying on the top side of the rail, which can result in contamination of the environment.
  • the device comprises a spray unit with which a predetermined lubricant dosage can be dispensed of between 0.02 and 0.06 g per m 1 rail, and preferably between 0.03 and 0.04 g per m 1 rail.
  • a predetermined lubricant dosage can be dispensed of between 0.02 and 0.06 g per m 1 rail, and preferably between 0.03 and 0.04 g per m 1 rail.
  • the quantities of lubricant applied to both the inner and the outer leg are hereby very small. Furthermore, generally less than half the quantity of lubricant for the outer leg is required for lubrication of the inner leg.
  • a further preferred embodiment comprises a device wherein the control means are adapted to determine, on the basis of the signal received from the vibration sensor, the number of axles that have passed the spray head and, when a preset number of axles have passed, to apply lubricant in each case in the predetermined lubricant dosage.
  • a system comprising an inner rail and outer rail arranged in the form of a curve in addition to the above stated device, wherein the device is positioned close to the inner rail for the purpose of applying lubricant to the upper surface of the inner rail.
  • the system comprises a second device which is arranged close to the outer rail for also applying lubricant substantially to the side surface of the outer rail.
  • a further preferred embodiment comprises a system wherein the rails form part of a points which is adjustable between straight-ahead position and a turn-off position, a detector is provided with which the position and/or the movement of the movable blade of the points can be detected, and the control means are adapted to lubricate the rails only when the points is situated in the turn-off position. Lubrication of the points in the straight-ahead position is after all unnecessary and would result in an unnecessary impact on the environment.
  • the invention also relates to a spraying agent reservoir for lubricating a rail track in said device, wherein the reservoir comprises a cylindrical housing, a piston displaceable in the housing, a lubricant outlet via which the lubricant can be discharged under the influence of the piston, and a fluid feed for feeding fluid with which the piston can be displaced, wherein lubricant is arranged in the housing.
  • a method for lubricating a rail comprising of:
