Definitions

  • the present invention relates to a method for setting up a prefabricated part, in particular a prefabricated plate for the construction of a slab track, which forms a route together with a plurality of prefabricated parts arranged one behind the other, with polygon points which determine an external geometry of the course of the route and a device for accommodating several Measuring prisms, which is arranged on a prefabricated part, in particular a prefabricated plate, for building a slab track.
  • EP 0 780 514 B1 discloses a method for spatially precise positioning of production facilities, which is controlled using reference points in such a way that rail fastening bodies are arranged at the desired location with the desired accuracy.
  • the manufacturing facility can be moved and can measure at least one reference point for selected positions.
  • the arrangement of the rail fastening bodies is controlled by the production device depending on the position to the reference points.
  • sensors are designed as television cameras on the production device, which detects the height of the production device in comparison to the height of the respective associated reference point.
  • the deviation of the actual from the target position is calculated, whereupon the production device is shifted in the longitudinal and transverse directions into the target position.
  • the rail fastening body is then positioned and fastened.
  • a disadvantage of this device is that a large number of reference points is required for precise laying of the rail fastening body in order to be able to carry out the positioning of the rail fastening body with the accuracy required for high-speed railways.
  • the reference points must be arranged along the route so that the manufacturing facility can use them as a guide. A lot of work is therefore required to create the reference points.
  • the position of a production device is precisely determined with the proposed method. However, the proposed method does not check whether the production device subsequently positions the rail fastening body correctly.
  • the method according to the invention is used to set up a prefabricated part, in particular a prefabricated plate for the construction of a slab track.
  • Several finished parts arranged one behind the other form a line.
  • the route composed of the finished parts has polygon points which determine an external geometry of the course of the route.
  • a measuring device in particular a tachymeter, is set up at a first polygon point and oriented with respect to at least one target point. Then measuring points of the finished part are measured based on this target point orientation with regard to their actual position and compared with their target position.
  • the finished part is then set up according to the difference between the actual and target position.
  • the orientation of the tachymeter and the measurement of the actual position of the measuring points of the finished part is done by creating a target line or orientation line between the tachymeter and the target point, from which the position of the measuring points is determined.
  • the win- point can be used. This is often the better and easier way to determine the position of the measuring point.
  • a tolerance of +/- 0.1 mm may be permitted.
  • the position of the finished part or its measuring points is from the target line, i.e. given the internal geometry with very high accuracy ..
  • the kinks between the individual sections of the route, which are determined by the finished parts, are particularly small. It is assumed that the finished parts are very precisely manufactured. The operation of high-speed trains on the prefabricated parts of the slab track is therefore very convenient and safe to perform.
  • the measuring points of the finished part are advantageously measuring prisms which are arranged on the finished part. They can either be placed on the finished part with a gauge that simulates, for example, the upper edge of the rails and thus indirectly indicate the position of the finished part, or they can be arranged directly on the finished part and thus directly indicate the position of the finished part.
  • a measuring prism arranged at a polygon point is used as the target point.
  • the measuring prism is particularly well suited for sighting through the measuring device or the tachymeter. If the measuring prism is arranged at a polygon point, the line between the tachymeter and the polygon point forms the orientation or target line at which the finished part is aligned. With a correspondingly precise positioning of the individual polygon points, the tachymeter and the measuring prism at the respective polygon point, a sufficiently precise target line is created, which enables the laying of finished parts with only slight kinks.
  • the target point is set up on a finely aligned, preferably on the last finely aligned finished part, the laying of the successive angle between the orientation line and the line between the tachymeter and the measuring point, and the distance of the measuring point from the tachymeter, and compared with target values. If these target values do not match the required actual values, the position of the finished part is corrected.
  • the target lines of the individual finished parts are part of the inner geometry of the route, ie they determine the neighborhood accuracy of successive finished parts.
  • the polygon points near the axis of the route are advantageously chosen. These polygon points close to the axis are subject to the parameters of the internal geometry to be maintained with regard to their neighborhood accuracy. This means that neighboring polygon points have only an extremely small deviation from the required internal geometry. Overall, the polygon points represent the outer geometry of the route section and can allow a greater tolerance in this regard. In the case of prefabricated parts for the construction of a slab track, orders of magnitude for the tolerance that can easily be achieved with the inventive measuring system are approximately +/- 0.2 mm with regard to the neighborhood accuracy or internal geometry.
  • the polygon points close to the axis have the advantage that they map the outer geometry of the line and thus enable the actual laying of the line on the axis defined by the polygon points.
  • the measuring points are advantageously measured with regard to their position in relation to the line between the tachymeter and the target point.
  • the decisive factor is the distance between the tachymeter and the measuring point and the angle between the finish line and the line from the tachymeter to the measuring point.
  • a tolerance of approximately +/- 1 mm is insignificant when laying a slab track.
  • the transverse deviation from the finish line can also be used to assess the accuracy of the measurement prefabricated parts even more precisely than is the case with the arrangement of the target point at a polygon point. This compensates for any inaccuracy when laying the last finely aligned finished part. This actually smoothes the actual inner geometry,
  • the finished part is advantageously carried by means of adjusting elements, in particular spindles, on a base, in particular a hydraulically bound base layer (HGT).
  • adjusting elements in particular spindles
  • HAT hydraulically bound base layer
  • adjustment elements in particular spindles
  • the adjustment elements are screwed to ground contact before measuring the actual position, a defined position of the spindles and the finished part is created, from which the finished part can be set up.
  • the spindle contact with the ground is determined by a predefined torque on the spindle.
  • a predefined torque on the spindle As soon as this torque is applied to the spindle or the screwdriver, a defined position of the spindle and the finished part is obtained, from which the finished part is then adjusted.
  • the difference between the actual and target positions is displayed first and released before the finished part is actually set up. This prevents the precast part from being set up incorrectly in the event of a faulty measurement and the measurement and setting up of the precast part having to be carried out from scratch.
  • the display can be used to perform a plausibility check and, if necessary, the measurement can be carried out again. If the spindles are adjusted using automatically controlled setting screwdrivers, the finished part can be set up very quickly, reliably and in a way that saves personnel.
  • the total station independently determines the actual position in all measuring points and then displays the adjustment or positioning data of the adjustment elements, in particular the spindles, by means of a display device.
  • the manual aiming of the individual measuring points by an operator is no longer necessary.
  • the finished part is set up, in particular by adjusting the adjusting elements, in particular the spindles. Then the measuring points are measured again and compared with their target position. If the difference is still outside the permissible tolerance, the fine adjustment process is repeated until the difference between the actual and the target position no longer exceeds a predetermined value.
  • the last measured values of the precision straightening process are advantageously stored as a measurement log in order to be able to document the position of the finished part and, if necessary, to be able to prove this to the client.
  • a device according to the invention which can be used in the implementation of the method according to the invention for setting up a prefabricated part, has a receptacle for a plurality of measuring prisms, which is provided for arrangement on a prefabricated part, in particular a prefabricated plate, for the construction of a slab track.
  • the device has a measuring prism holder which holds at least one measuring prism at a predetermined position on the finished part or at a predetermined distance from the finished part when the device is arranged on the finished part.
  • the device has the particular advantage that, in particular in the case of a plurality of measuring prisms, it creates the assignment of the individual measuring prisms to one another and thus makes it unnecessary to adjust these measuring prisms to one another when fine-tuning a finished part.
  • the device forms a measuring gauge for setting up the finished part, so to speak.
  • the measuring prisms are located at defined positions in relation to the finished part and can therefore be observed when measuring any number of finished parts. After a finished part has been set up, the device is removed from this finished part and moved to the next finished part. It only has to be roughly positioned there in order to be able to create the target points for the measurement of the finished part.
  • the measuring prism of the device is advantageously arranged in the region of a supporting spindle of the finished part. As a result, the measured value on the measuring prism can be converted directly into an adjustment of the supporting spindle. It is hereby established that when the spindle is adjusted by a certain amount, the position of the measuring prism is also changed by this amount. An additional conversion is therefore not necessary.
  • the measuring prism is arranged in the area of a rail base, the support of a rail on the prefabricated part of a slab track can be measured.
  • the measuring prism can be placed directly on the rail support point or, according to a particularly advantageous embodiment, can be arranged at a predetermined distance from the rail support point and thereby, for example, correspond to the distance of the upper edge of the rail from the finished part.
  • the prefabricated plate is aligned according to the course of the rail. This ensures a particularly comfortable operation of the rail vehicle since shocks are avoided.
  • additional special adjustment measures and compensation measures on the rails are hardly necessary anymore when they are being installed. This arrangement also compensates for differences in height in the surface of the finished part in the vicinity of the spindle and thus results in a uniform, defined course of the rails.
  • the measuring prism support has a device for the measuring prism which can be placed on a rail base and then corresponds to the distance of a rail head from the rail base.
  • the device thus defines a rail head at the predefined distance from its bearing point.
  • a substructure which is arranged, for example, in the form of rubber plates under the rail foot, can also be taken into account for the corresponding distance.
  • the device according to the invention can be moved on the finished part.
  • wheels can be connected to the device, for example, which guide the device on the finished part and can be pushed onto the subsequent finished part after the finished part has been set up.

  • the servomotor receives a corresponding signal, it is set in motion and rotates the supporting spindle of the finished part by a predetermined amount in order to raise or lower the finished part.
  • the servomotor aligns the finished part both in height and transversely to the longitudinal axis of the finished part.
