Definitions

  • the invention relates to a concrete sleeper for a railway track, with a concrete body and a measuring device having a sensor for detecting loads and/or deformations acting on the concrete sleeper during operation.
  • a threshold is proposed which is designed in two parts and has a trough-like base body in which a measuring piston is mounted so that it can move vertically.
  • the top of the volumetric flask serves as a support for a splint.
  • a pressure sensor is located inside the concrete sleeper between the base body and the measuring piston. When a rail vehicle drives over the concrete sleeper, the vertical forces occurring at the moment can be recorded.
  • the DE 38 44 663 A1 proposes a sleeper for a railroad track that has integrated fiber optic sensors to detect compressive and bending stresses.
  • a threshold which has a releasably attachable infrared sensor.
  • the infrared sensor is used to monitor the temperature of rail vehicle components.
  • the invention is based on the object of specifying a concrete sleeper with which the detection of loads occurring during operation can be carried out more simply and flexibly.
  • a concrete sleeper of the type mentioned at the outset is provided according to the invention with at least one recess formed by a hollow profile that is firmly and integrally connected to the concrete body of the concrete sleeper, in which the measuring device can be inserted or inserted in a removable manner, with the hollow profile having an exact Contact surface forms for the measuring device and loads acting on the concrete sleeper can be transmitted directly to the measuring device via the hollow profile.
  • the concrete sleeper according to the invention allows the measuring device to be introduced as required if a measurement is actually to be carried out. If no measurement is to be carried out, the concrete sleeper can be used like a conventional concrete sleeper that does not have a measuring device. In this way, any number of concrete sleepers according to the invention can be installed along a rail track to accommodate a measuring device are prepared and appropriate. If necessary, one or more concrete sleepers according to the invention are then provided with the measuring device. For this purpose, the measuring device is inserted into the respective mount of the concrete sleeper. In this way, different sections of the rail track can be examined.
  • the advantage of the invention is that only a single measuring device or possibly several measuring devices are required, which are not installed permanently and are installed at a desired position to carry out a measurement.
  • the measuring device or the multiple measuring devices can be installed exactly at a specific point on the rail chassis in order to carry out a measurement, efficient use is possible.
  • the conventional concrete sleepers mentioned allow only one measurement at the installation site of the corresponding concrete sleeper. This results in the advantage that the detection of loads occurring during operation can be carried out simply, flexibly, purposefully and cost-effectively.
  • the recess is formed by a hollow profile which is integrally connected to the concrete.
  • the hollow profile can be a metal profile, for example, in particular a steel profile or an aluminum profile.
  • the hollow profile forms an exact contact surface for the measuring device so that measurements can be carried out precisely and reproducibly.
  • the hollow profile is firmly connected to the concrete body of the concrete sleeper, so that loads acting on the concrete sleeper are transmitted directly to the measuring device via the hollow profile.
  • a hollow profile designed as a metal profile has a higher modulus of elasticity than the concrete surrounding it. The reduction in rigidity caused by the recess in the concrete body is approximately compensated by the hollow profile.
  • the hollow profile is designed in such a way that the concrete sleeper according to the invention behaves approximately like a conventional concrete sleeper that has no recess. Carrying out a measurement using the concrete sleeper according to the invention thus makes it possible to realistically record the loads acting on conventional concrete sleepers during operation of the rail track.
  • the hollow profile of the concrete sleeper according to the invention has a rectangular or square or round cross section.
  • Such hollow profiles are commercially available.
  • the cross section is rectangular or square.
  • a rectangular or square cross-section has upper and lower inner surfaces that face each other. These areas can be used to arrange the measuring device exactly at a desired position in such a way that the loads that occur are transferred from the concrete sleeper to the measuring device via the hollow profile.
  • the senor of the measuring device prefferably be accommodated in a sensor housing which can be inserted or inserted into the recess.
  • the sensor of the measuring device can thus either be inserted directly into the hollow profile, alternatively the sensor can be accommodated in a sensor housing.
  • the sensor housing protects the measuring device from environmental influences and ensures high quality of the recorded measurement data.
  • the sensor housing is optional. If the measuring device is used without a sensor housing, the recess, in particular the hollow profile, can be closed at the free end, for example by a plug, a flap, a cover or the like.
  • the senor can be fastened or is fastened in the recess in a form-fitting and/or force-fitting manner by means of a clamping device.
  • a sensor housing in which the sensor is accommodated, it can alternatively be provided that the sensor housing can be fastened or fastened in the recess in a form-fitting and/or force-fitting manner by means of a clamping device.
  • the recess is formed by a hollow profile, the sensor or the sensor housing is fastened in the hollow profile in a form-fitting and/or force-fitting manner by means of the clamping device.
  • the form-fitting or non-positive attachment ensures that the loads occurring during operation, in particular vertical forces, on the Measuring device are transferred, so that an accurate metrological recording of the loads is possible.
  • the non-positive attachment can also be done by a magnet.
  • a preferred variant of the concrete sleeper according to the invention provides that the clamping device can be inserted into the recess and is supported on the one hand on an inner surface of the recess and on the other hand on an outer surface of the sensor housing.
  • the clamping device can thus be inserted into the recess, possibly into the hollow profile, and braced there.
  • the clamping device can have a first clamping plate which interacts with a second clamping plate in such a way that the overall thickness of the two clamping plates lying on top of one another can be adjusted by a longitudinal displacement of the two clamping plates lying on top of one another.
  • the first and/or the second clamping plate is shaped in such a way that a longitudinal displacement of the two clamping plates results in the desired change in thickness.
  • the concrete tie comprises the first clamping plate and the second clamping plate.
  • one of the clamping plates can be permanently connected to the measuring device.
  • One of the clamping plates can thus also be designed as an outside of the measuring device.
  • a clamping plate is connected in one piece to the measuring device.
  • the first clamping plate can have a threaded bore and the second clamping plate can be longitudinally displaceable by means of a screw passing through the threaded bore.
  • the screw By turning the screw, the required longitudinal displacement of one clamping plate can be effected, thereby displacing the other clamping plate to change the overall thickness of the two clamping plates.
  • the two clamping plates can be clamped in the recess, in particular in the hollow profile.
  • One of the clamping plates is supported on an inside of the recess, in particular on the inside of the hollow profile.
  • the other clamping plate is supported on the measuring device, possibly on a sensor housing.
  • An opposite side of the measuring device, possibly of the sensor housing is supported on an opposite side of the recess, in particular of the hollow profile.
  • the clamping plates each have a ramp profile, with the two ramp profiles being formed at least approximately in opposite directions to one another.
  • a ramp profile has one or more inclined surfaces.
  • the clamping plates can also have a sawtooth profile with several inclined surfaces.
  • the two clamping plates could also be designed as wedge profiles, so that when there is a relative displacement to one another in the longitudinal direction, the required change in the overall thickness is brought about, as a result of which the clamping is achieved.
  • the sensor housing can preferably be designed as a tube.
  • the tube can preferably have a round or an angular cross section.
  • a variant of the concrete sleeper according to the invention provides that the recess is designed as a through opening.
  • the through-opening can be penetrated by the hollow profile.
  • the through opening preferably extends in the longitudinal direction of the concrete sleeper.

  • a first measuring device can be used starting from one end and a second measuring device starting from the opposite end.
  • the concrete sleeper can have two or more recesses, which preferably extend inward from both ends in the longitudinal direction.

  • a measuring device can be arranged in the center of the sleeper, preferably near the top of the sleeper.
  • the senor is designed as a laser sensor, which has a transmitter emitting laser light and a receiver which are arranged at a distance from one another, the laser sensor being designed to detect a load and/or a load acting on the concrete sleeper or to detect a deformation.
  • the laser sensor includes a measurement path formed between the sensor and the receiver. The transmitter and receiver are aligned so that the laser light hits a specific position on the receiver. If the sensor is subjected to a load, in particular a vertical force, this force causes a bending load to be exerted on the measuring device and the laser light strikes the receiver at a different position. This deviation is detected by the sensor. The deviation depends on the load acting on the concrete sleeper. Accordingly, the occurring load can be detected and characterized by evaluating the sensor signal.
  • the measuring device is positioned in the recess in such a way that the sensor is located at least approximately below a rail bearing surface or in the region of the center of the sleeper. If necessary, corresponding sensors can be located under both rail bearing surfaces.

  • the following steps can be carried out in advance: Positioning at least one force sensor with several concrete sleepers for detecting support point forces, determining which concrete sleeper is subject to the decisive, in particular the greatest, load, and inserting the measuring device into the concrete sleeper with the greatest Burden.
  • the concrete sleeper 1 is a side view of a concrete sleeper 1, 2 12 is a view of the concrete sleeper 1 in the longitudinal direction rotated by 90 degrees.
  • the concrete sleeper 1 comprises a cuboid base body 2 made of concrete. Sleeper blocks 4 are formed at both ends of the concrete sleeper 1 ; in this area, the concrete sleeper 1 has a raised upper side 5 with a rail support 6 .
  • the concrete sleeper 1 is provided for several tie rods 7 .
  • a total of six tie rods 7 are provided, the number of tie rods is determined depending on the expected loads and can vary.
  • the recess 8 is formed by a hollow profile 9 .
  • the hollow profile 9 consists of a steel alloy and has a rectangular cross section.
  • the hollow profile 9 is arranged in the base body 2 in such a way that the longer sides of the rectangle are aligned in the vertical direction.
  • the hollow profile 9 is cast during the manufacture of the base body 2 of the concrete sleeper 1, as a result of which it is firmly connected to the base body 2.
  • the recess 8 formed by the hollow profile 9 is designed as a through opening and thus extends from one end of the concrete sleeper 1 to the opposite end.
  • the recess 8 is designed to accommodate a measuring device. Due to the configuration of the hollow profile 9 as a through opening, a measuring device can be inserted into the hollow profile 9 from both ends of the concrete sleeper 1 . The measuring device is only used when required, if no measurement is to be carried out, the recess 8 is empty or hollow. To protect against environmental influences, the recess 8 can be closed with a plug or a cover.
  • the measuring device 10 includes a sensor housing 11.
  • the sensor housing 11 is designed as a slide-in tube and accommodates the sensor 12 in its interior.

  • figure 5 12 is a plan view of the sensor case 11 and 6 12 is a longitudinal view of the sensor case 11.
  • FIG. In 6 it can be seen that the sensor housing 11 has a plurality of openings 13 on its upper side. In this exemplary embodiment, two openings 13 extending in the longitudinal direction are provided, in addition there are two smaller openings 14 which have an oval contour.
  • the size, position and number of the openings 13, 14 is selected such that the reduction in rigidity caused by the recess 8 in the base body 2 of the concrete sleeper 1 is at least approximately compensated for by the sensor housing 11.

  • the transmitter 15 and the receiver 16 are matched to one another in such a way that the laser light hits a specific point on the receiver 16 . In 1 one can see that the sensor 12 is located exactly below a rail support 6 when installed. If the concrete sleeper 1 is run over by a rail vehicle, the vertical force is transmitted via the rail to the rail supports in the base body 2 of the concrete sleeper 1 .
  • This vertical force causes bending stress to act on the sensor housing 11 .
  • This bending stress occurring between the transmitter 15 and the receiver 16 causes the laser light emitted by the transmitter 15 to occur at a different point on the receiver 16 .
  • a measurement signal supplied by the laser sensor is a measure of the bending load. The measurement signal indicates the deviation between the position at which the laser light hits without a load and the position at which the laser light hits when a rail vehicle is loaded. Accordingly, by detecting and evaluating the measurement signal supplied by the sensor 12, conclusions can be drawn about the magnitude and the time profile of a load that occurs.
  • the sensor housing 11 In order to obtain an accurate measurement signal, it is necessary for the sensor housing 11 to be coupled to the recess 8 or to the hollow profile 9 forming the recess 8 in a form-fitting and/or force-fitting manner. In this case, the loads generated by the rail vehicle driving over the concrete sleeper 1 are transmitted to the sensor housing 11 and the sensor 12 . It is therefore essential that the sensor housing 11 is firmly accommodated in the concrete sleeper 1 .
