Description

Title: Frame for the detection and measurement of the longitudinal profile of the rail
Description
The present invention relates to a frame for the detection and measurement of the longitudinal profile of the rail.
The object of the invention is to provide a frame, which can slide on railway and tram rails, for the detection and measurement of the longitudinal profile of the rails, which has a high degree of reliability and which can be transported in a simple and easy way on the rails to be measured.
This object is achieved according to the invention with a frame as described in claim 1.
The present invention is further clarified hereinafter in a preferred embodiment thereof reported purely by way of example and not by way of imitation with reference to the attached drawings, in which:
Figure 1 shows a perspective view of the frame in a form ready for use thereof,
Figure 2 shows it during transport,
Figure 3 shows it according to the front view of Figure 2
Figure 4 shows it in side view.
As can be seen from the figures, the frame according to the invention comprises two vertical uprights 2 to which two lifting cylinders 8 are articulated in correspondence with hinges 6, the stems 10 of said cylinders having the ends articulated to two brackets 12 which are in turn articulated to the uprights 2 by means of hinges 14.
The end of each bracket 12 has a supporting frame 16 for supporting a hydraulic cylinder 18 whose piston 20 is integral with the measuring unit, indicated generically with 22. Integral with the lower surface of the frame 18 is a plate 24 to which is welded a recirculating ball bearing tube 26 housing a support 28, one end of which is integral with the measuring unit 22.
In particular, the measuring unit 22 consists of a plate 30 to which a pin 32 of a bracket 34 is connected, which supports a linear electronic transducer 36 with an internal spring, and from which two rollers 38 protrude for support, as will best be seen later, on the surface of the rail 40 to measure the longitudinal defects of the short wave and the long wave. The transducer is connected to a PLC not shown in the drawings.
The lower end of the transducer is integral with a probe 42. Integral with the same bracket 34 is a bracket 44 to which are connected lateral guide rollers 46 resting on the sides to compensate for the variation in the gauge of the rails.
The invention also provides for the use of keys 48 respectively for the removable connection of the measuring unit 22 with a bracket 51 integral with the frame 16.
The bracket 51 is equipped with a slot 52 for centering, after locking to the frame 18, the rollers 38 and 46 with respect to the head of the rail 40. This centering operation is necessary because, during the lifting-lowering movement of the frame 16 via the cylinder 8, if these operations are not carried out correctly the measuring unit 22 risks being damaged because it would position itself outside the rail head due to the lateral movement of the support 26.
The operation of the frame provides that the brackets 12 are positioned in a horizontal configuration and that the cylinder causes the piston to come out to bring the measuring unit into contact with the wheels. Once the rollers have been positioned on the rail head, the key 48 is retracted to allow lateral movement, driven by the compressed air of the piston 20 of the measuring unit 22 with respect to the rail. The frame is then advanced on the rails such that the transducer 36 transfers the detected data of the rail profile to the PLC. At the end of the measurement, the key 48 is inserted again before lifting the unit 18 and blocking it with the key 53.
The invention also provides for the use of another key 50 respectively for locking the oscillatory movement between the measuring unit 22 and the support 26.
The oscillatory movement of the measuring unit 22 is necessary when measuring very small radius curves (trams) such that the edges of the two wheels 486, during curve negotiation, are always in contact with the internal part of the rail and consequently the probe 42 always measures at the center of the rail head.
On the other hand, when measuring rails with very large radii of curvature (railway) it is not necessary to have the simultaneous lateral contact of the two rollers 46 because the probe 42 is positioned very close to the center of the rail.
Therefore it is advisable to lock the key 50 and eliminate the oscillatory movement in order to increase the working speed by having a more stable measuring system with fewer vibrations.
