In practice, sensor devices which are intended to be fastened to a rail of a railway track system are often screwed to the neck of the rail by means of two fastening units in the form of two screw connections.For this purpose, these sensor devices have two holding sections, each with a continuous receiving opening for the two fastening screws of the screw connections to pass through. However, this type of fastening has the disadvantage that two receiving openings for the two fastening screws of the screw connections must be created in the rail, which is a high technical effort. An example of such a fastening of sensor devices is known from the publication "Electronic Axle Counting Point ZP 43, Siemens AG, 2006". This discloses a sensor arrangement referred to as "Double Sensor DEK 43" with two sensor devices to be fastened to opposite sides of the rail. One of these sensor devices is a transmitting part and the other sensor device is a receiving part. Two fastening units in the form of screw connections are used to fasten both sensor devices to a rail of a railway track system.Starting from a generic device, the invention is based on the object of simplifying and improving the fastening of at least one sensor device, which is designed as a structural unit 2023P01712DE 2 and which has two holding sections, to a rail of a railway track system.

The longitudinal rail direction x can also be referred to as the "x-direction" or "longitudinal axis," the transverse rail direction y can also be referred to as the "y-direction" or "transverse axis," and the vertical rail direction z can also be referred to as the "z-direction" or "vertical axis." The rail also has a head 1, a neck 2 with sides 3 and 4, and a foot 5. The foot 5 has side edges 6 and 7. In the illustrated embodiment of arrangement A, side 3 is an outer side of the rail S and side 4 is correspondingly the inner side of the rail S.

The clamping jaws SpB1a i , SpB1b i , SpB2a i , SpB2b iare selected as an i-th clamping jaw embodiment from a clamping jaw set, which provides a number n>1 different clamping jaw embodiments, wherein the selected i-th clamping jaw embodiment is adapted to the rail profile of the rail S and wherein the remaining clamping jaw embodiments of the clamping jaw set are adapted to other rail profiles of other rails. The holders H1a j , H1b j , H2a j ; H2b jare selected as a j-th holder embodiment from a holder set which provides a number m>1 of different holder embodiments, wherein the selected j-th holder embodiment is adapted to the rail profile of the rail S and wherein the remaining holder embodiments of the holder set are adapted to other rail profiles of other rails. The selection of the required embodiments of the clamping jaws and holders from the said sets advantageously ensures simple adaptation to different rail profiles without adjustment during installation on the rail. The installation of the device V and thus also the installation of the sensor device SE1 or the sensor device SE2 by means of the device V on site is thereby considerably simplified; in particular, the installation time is shortened and installation errors are avoided.In the illustrated embodiment of arrangement A, the first sensor device SE1 is a transmitting part of an inductively acting rail contact DEK, whose operation is based on a change in the coupling intensity of two resonant circuit coils, and the second sensor device SE2 is a receiving part of the inductively acting rail contact DEK assigned to the transmitting part, whose operation is based on a change in the coupling intensity of two resonant circuit coils—namely, a resonant circuit coil of the transmitting part and a resonant circuit coil of the receiving part. Tests have shown that the inclination of the receiving part SE2 by the acute angle α to the rail transverse direction y achieved by the device according to the invention results in improved wheel detection of the rail contact DEK.Because the mounts are manufactured using standard manufacturing processes from standard materials, particularly laser cutting and sheet metal bending, they are very easy to produce. They are also characterized by their low weight, which dampens vibrations.
