Definitions

  • the invention relates to an apparatus for the measurement of the quality of rails, and of the kind disclosed in the preamble to claim 1.
  • a measuring table for measuring apparatus for the measuring of the quality of rails, said measuring table being suspended in a bogie under a railway coach.
  • the measuring table is flex ⁇ ibly suspended in a measuring frame which, via hinge-like elements, is suspended in longitudinal beams between the free journals of the wheel axles.
  • the measuring table is hereby positioned between two wheel axles in a bogie.
  • the relative displacements of the measuring table in the lat ⁇ eral direction in relation to the coach body are measured by means of measuring equipment placed on the underside of the coach body, said measuring equipment being in engage ⁇ ment with the measuring table. Via lenses, mirrors etc.
  • beams of light are transmitted from the measuring table towards the rails, so that their quality with regard to displacement of the track element and differences in the distance between a pair of rails can be measured during railway operations. Since the measuring table is constantly moving in relation to the position of the track element, the method of measurement is difficult to use, the reason being that it is difficult to obtain measuring results which are precise enough to be used in a qualititive evalu ⁇ ation of the rails.
  • the resulting measuring apparatus is one which can be mounted on the bogie in a normal railway coach and carry out the desired measurements under full operational speed.
  • the core of the apparatus is a measuring frame which is suspended in such a manner that to all intents and purposes it always lies at a certain, fixed distance above the rails during operations. Since the measuring frame is continuously adjusted in the transversal direction in relation to the rails, it is poss ⁇ ible to achieve a relatively short distance, e.g. 13-20 cm, which provides many technical advantages and which gives better and more accurate measurements than those obtained with the known measuring systems.
  • This suspension of the measuring frame also means that it is mechanically isolated from the rails.
  • the types of measurements it is possible to carry out are almost unlimited, in that the fundament on which the measurements are based is a measuring frame which during operations always lies in a certain position above the track element, and can hereby form the basis for the mounting of different types of measuring apparatus.
  • the measuring frame is continuously servo-controlled in the vertical direction and the lateral direction. This posi ⁇ tioning of the measuring frame close to the rails results in greater measurement solubility and considerably less measurement noise than with the known systems, and thus the desired accuracy of measurement can be achieved during full operational speed.
  • correction signals are obtained for use in the cor ⁇ rection of the measurement results if the measuring frame is displaced in the horizontal direction in relation to the rails, and for the adjustment of the horizontal position of the frame.
  • the inertial measuring system comprises at least one gyro for each measurement direction and at least one accelerometer for each measurement direction.
  • the starting point for the measurements and the servo- control of the frame is thus the wheels and the wheel axle, in that the position of the frame is regulated on the basis of the distance to the wheel axle and measurements of the distance between the frame and the rails.
  • a robust measuring frame is achieved, the four corners of which can be regu- lated individually with regard to the distance of the frame from the rails. Consequently, it is not merely the frame as a whole which is adjusted in height in relation to the rails, but also the individual parts of the frame.
  • the frame must be configured of robust and rigid material, e.g. aluminium profiles.
  • the suspension elements must be configured in such a way that they can absorb those movements which can be permitted.
  • the measuring frame can be positioned relatively close to the upper edge of the rails, so that laser measuring devices with limited ranges of measurement can be used, in that these are dis- posed relatively close to the head of the rail.
  • This solves many problems where measurement technique is concerned, and also reduces the cost of the apparatus.
  • the measuring frame according to the invention makes it poss ⁇ ible to use commonly-known measuring equipment, e.g. a commonly-known laser-scanner.
  • the apparatus according to the invention is preferably con ⁇ figured as disclosed and characterized in claim 6, whereby the possibility is provided of being able to automate the measurements and postpone parts of or the whole of the data processing of the measurement results until a later date.
  • the apparatus according to the invention is preferably con ⁇ figured with laser-scanners as disclosed and characterized in claim 7, whereby the possibility is provided of under- taking the measurements at very high operational speeds, so that the measurements do not interfere with the normal railway operations on the track.
  • the apparatus according to the invention can be configured as disclosed and characterized in claim 9, whereby the possibility is provided of carrying out a total measurement of the cross-sectional profile of the rail head, which in some cases is of great practical signifi ⁇ cance and provides very valuable measurement results.
  • fig. 1 shows in perspective parts of a bogie for a rail ⁇ way coach on which there is mounted a measuring frame according to the invention
  • fig. 2 shows the measuring frame and the wheels from fig. 1 seen in the direction at right-angles to a wheel axle

  • figs. 1 and 2 are seen parts of an ordinary standard bogie 2 for a railway coach, which with wheels 4 mounted fixedly on a rigid axle 5 runs on a track element consist ⁇ ing of a pair of rails 6.
  • fig. 1 is shown the use of a commonly-known, rectangular, robost bogie frame 3, which is also the basis for suspension of the measuring frame ac ⁇ cording to the invention.
  • the measuring frame 1 consisting of four frame parts la, lb, lc and Id, is assembled to form a rectangular frame which is positioned under the wheel axles.
  • the frame 1 con ⁇ sists of four longitudinal girders which are joined in the corners, possibly with special corner joints which enable the frame parts to rock slightly in relation to one another.
  • the frame 1 is suspended in the bogie frame 3 by means of a number of suspension elements 7, in the shown example by four suspension elements 7.
  • the suspension el ⁇ ements 7 are adjustable so that they can raise or lower the measuring frame 1 at the suspension points as a function of electrical signals received from a computer, which will be described later.
  • the measuring frame 1 is also coupled positionwise to the bogie frame 3 by means of the measuring system 9,10, which in a commonly-known manner with movable arms and the like is in engagement with the measuring frame and can continuously measure the distance between the bogie frame 3 and the axle journals 5' on the wheel axles 5. There is hereby measured the relative displacement of the axle ends 5 ' in relation to the bogie frame 3.
  • the measuring frame 1 there are also mounted four laser scanners 11, which partly measure the distance of the frame 1 from that rail 6 towards which the scanner is directed, and at the same time scan the cross-sectional profile of the head of the rail.
  • the measuring frame 1 there is mounted at least one inertial measuring apparatus or system 8 which measures the acceleration of the frame in three directions and the dimension in the three directions, as shown sche ⁇ matically by the arrows 8' .
  • the apparatus comprises at least one gyro and at least one accelerometer for each direction of measurement, and electronic circuits to carry out the necessary calculations.
  • Such an apparatus can be purchased on the present market, or can be configured using commonly-known equipment.
  • Fig. 2 shows in more detail how the laser scanners 11 are directed towards the rails 6, so that the cross-sectional profile of the rail head can be scanned, while at the same time the distance between the frame 1 and the rail 6 is continuously measured.
  • the measuring frame which constitutes a kind of stabilized platform for measuring instruments, is arranged to be con- tinuously positioned at a fixed distance and position over the track element.
  • the frame parts la, lb, lc and Id are shown, but there is naturally nothing to prevent a platform or the like from being mounted be ⁇ tween the frame parts lc and Id for the support of measur- ing instruments etc. All measurements on the rails are hereafter undertaken in relation to the platform or the frame 1.
  • the platform is built as an additional frame around and under the normal bogie frame 3.
  • the suspension elements can be commonly-known adjusting devices which can be controlled by a servo mechanism, e.g. electrically-driven actuators.
  • Fig. 3 of the drawing is a block diagram covering the whole of the measuring apparatus.

  • the coupling is effected through input or interface circuits 15, 16, through which the above-mentioned transducers are also coupled to the computers.
  • control signals are generated which, via one or more interface circuits 17, are fed to the four suspension elements 7, which ensure that the measuring frame 1 is always positioned at a fixed distance from the track el ⁇ ement 6.
  • the signals from the four laser scanners 11 are also fed to the computers, preferably to the computer 14, which also receives digital data from the other computer 13, so that the computer 14 can continuously calculate the cross- sectional profile 20 of the two rails and other parameters for the rails.
  • the parameters measured can either be shown directly on a display 18, 21, or stored in suitable data memories or sent further to a central computer store as shown in position 19, 22.
  • the data processing unit itself con- sists of two computers 13, 14 which cooperate via a data bus, but there is naturally nothing to prevent a practical and usable solution from being configured with one computer or a number of cooperating computers or PLCs.

Abstract

L'invention concerne un dispositif de mesure permettant de déterminer l'état d'un rail (6) pendant l'exploitation d'un chemin de fer. Ce dispositif comprend un cadre de mesure (1) qui supporte des scanners laser optiques (11) dirigés vers les rails (6). Le cadre (1) peut se déplacer par rapport au châssis de boggie (3) étant donné qu'il est suspendu à celui-ci par une pluralité d'éléments de suspension (7) qui sont réglés par une servo-commande en fonction des mesures. Ainsi, le dispositif de mesure (1) est toujours, même lorsque le véhicule ferroviaire se déplace à la vitesse maximum, à la même distance des rails (6), de sorte que les instruments de mesure ou autres montés sur ce cadre de mesure (1) peuvent effectuer des mesures précises permettant de déterminer l'état des rails (6).
