Definitions
- the present invention relates to a vehicle for measuring the geometrical state of a railroad compared to the theoretical geometric configuration of said track, comprising a rigid frame constituting the base of measurement supported by rolling means on the rails of the railway, means arranged for note the geometrical configuration of the track, and operating resources to determine the degradation of the geometric configuration noted in relation to the theoretical geometric configuration and indicate the any discrepancies representing said degradation.
- the present invention also falls within the latter. category, namely we offer a measurement vehicle whose chassis constitutes the so-called reference base relative. Measurements relative to this relative base can be done in different ways that don't are not the subject of the present invention, but by the next we will talk about two different means, namely the use of three measuring trolleys integral with this reference base which is the chassis and, the second by means of a so-called inertia platform and two measuring trolleys for measuring the deviation in a vertical plane and in a plane horizontal between the two measurement points corresponding to the two measuring trolleys.
- the object of the present invention is to provide a measuring vehicle, the base of which is the chassis of said vehicle making it possible to eliminate the influence of deformations of said chassis, in particular when it is a particularly long chassis.
- the vehicle according to the invention is characterized by the fact that the chassis is provided with means optoelectronics arranged to measure deformations chassis elastic when moving on said vehicle track, said deformation values of the chassis being supplied to the operating resources for correct the geometrical configuration values identified.
- the advantage of the vehicle according to the present invention is the fact that any chassis deformation due to track irregularities and also to deformations inherent in the size of the chassis are measured and supplied to the operating resources for ability to correct measurements taken against frame.
- the means optoelectronics include a receiving device optics formed by sensors each provided with several photosensitive elements for receiving beams light emitted by light sources located near distance from the receiving measuring device of each side of it, two lens systems arranged in the area between the light sources of two sides of the receiving device, each source light being associated with at least one of the sensors receiving the light beams emitted by the source corresponding light and passing through the matching lenses, the two lens systems being made up of a fixed lens whose axes optics are aligned and that the elements photosensitive from each sensor are aligned in such a way way that the light rays passing through the lens concerned are projected according to their angle of incidence on a corresponding area of the sensor, the device and the light sources being integral with said chassis.
- Optoelectronic means are those described in patent EP-B-0.518 822 of the Applicant, device which was originally intended for measure the deformations of the railway. These means are now used to measure only the chassis deformations and are arranged so fixed, i.e. the light sources at both chassis ends while the optical receiver towards the middle of the chassis.
- the track raising device includes three carriages track gauges to detect the geometric coordinates of the track at three points by relation to the chassis (9) in the layout plane and in the profile plan.
- These means are arranged in principle to the vertical, on the one hand, of the light sources and, on the other hand, from the receiving device.
- These devices measure the position of three points relative to the chassis, said position being corrected by the possible deformation of the chassis noted by the optoelectronic device so the actual position of these three points is known.
- the probes are either mechanical (wheels) or electronic devices, either optical.
- the vehicle is fitted with two track trolleys to raise the geometric position of the track at two points by relation to the chassis and a reference platform absolute three-dimensional called inertial, said platform being arranged to pick up the difference vector between the chassis and the North and between the chassis and the horizontal plane thus allowing determine the curvatures of the track in the plane horizontal and vertical as well as the superelevation.
- the platform inertial is provided in three accelerometer planes, gyroscopes and signal processing means to determine particular track faults.
- said platform is secured to a point on the chassis, preferably a point common to the chassis and one of the feeler trolleys.
- the platform inertial is integral with the undercarriage of the feeler carriage or its structure and a means of signal processing to determine faults in the geometry of the track.
- the position of said platform relative to the chassis is measured each time by sensors, which it is equipped with which means that this platform can be integral with a device independent of the chassis.
- Said platform can be equipped in all three measurement plans for accelerometers and gyroscopes and signal processing means for determining very specific faults in the track.
- the inertia platform can be carried out either by mechanical means or by optoelectronic means. These platforms have been used for a long time in aviation to determine the position of an aircraft and also in other circumstances in mainly aeronautical applications but not only.
- measurement bases can be used for the track survey, the purpose of the present invention being to provide a vehicle whose possible deformations of the chassis during its rail travel can be measured so that they don't spoil the results measuring the actual position of the track and incidentally to propose a measurement base using the performance of an inertial platform.
- Figure 1 is a schematic view of the device optoelectronics proposed for the measurement of chassis deformations as described in Patent EP-B-0 518 822 of the applicant.
- Figure 2 shows a measurement vehicle
- Figure 3 shows a schematic plan view and cuts along the chassis of said measurement vehicle.
- Figures 4, 5 and 6 schematically show a variant of the present invention using an inertial platform.
- Two sensor strips 4, 5 are arranged in the middle of the optical axis formed by two lenses 1, 2 of semi-circular section. These bands are arranged such that depending on the position of the sources respective light beams, concentrated light rays by the lenses are projected as an end light beam along the sensor strips.
- a light source A located on the axis optical 3 is projected at location A 'of the strip of sensors 5.
- a light source B arranged at the outside of the optical axis is respectively projected onto point B 'of the sensor strip 5.
- the distance between the point projected on the strip of sensors and the point of the optical axis on the strip of sensors is a measure of the angle ⁇ of the source light relative to the optical axis at this point.
- a glass filter colored 6 and polarizing filters 7, 8 are arranged in front of lens 2. You can get through them that only light from a specific light source can reach the sensor bands and that a signal well defined can be produced.
- CCD Charge Coupled Device
- the two polarizing filters By arranging the two polarizing filters so that they are oriented 90 ° to each other, a large part of the incident light is absorbed. In the case where only very powerful light sources are used, only a very small part of these light rays can reach the sensors and all other foreign light sources are filtered.
- the angles of one or multiple light sources on each side of the measuring device with respect to the optical axis can be determined and analyzed.
- a measurement vehicle V is provided with a chassis 9, three bogies 10, 11, 12 and three feeler trolleys 13, 14, 15 for measuring and tracing a formed track rails R with respect to the base which is constituted by the chassis 9.
- the feeler trolleys 13, 14, 15, in the case in point, are carts fitted with rolling wheels on the way but we could very well have electronic carts with devices electronic or optical to measure any deformations of the track with respect to base 9.
- the chassis 9 is fitted with an optoelectronic device derived from the one briefly described in relation to the Figure 1 which is the subject of patent EP 0 518 822.
- FIG 4 we schematically represent a chassis 19 fitted with two bogies 20, 21 and feelers track 22, 23 to measure the position of two points a track formed by rails R 'relative to the chassis 19.
- an inertial platform P shown schematically, which in the present case is fixed on the chassis 19.
- the device optoelectronics previously mentioned formed of a N 'lens system and L'1 light sources, L'2, L'3, L'4 is also used to be able to measure the deformation of the chassis 19, the measurement base being formed by two feelers 22, 23 and the platform inertia.
- the inertia platform measures another angle ⁇ 'which is not due to a deformation of the track, but sags on the bogie 21 of the chassis. This sagging will be corrected by the fact that the distance between the chassis and the bogie is not the same concerning the two bogies which allows to obtain a correct measurement because the two results will be compensated in the electronic computing device that holds always counts any distortions as well of the chassis raised by the device N ', L'1, L'2, L'3, L'4, by the measurements carried out on the track layout by feelers 22 and 23 and by elements detected by the inertia platform P at know the vector difference between the position of the chassis and magnetic North. Indeed, the platform of inertia not only measures the angle in a plane perpendicular to the track but also in a horizontal plane which completes the measurement concerning track bends and also cant.
- the measures can also be performed using the position measurement by satellites known as the GPS designation.
