METHOD FOR INSTALLING A PRE-FABRICATED UNIT AND DEVICE FOR RECEIVING MEASURING VEES}

The present invention relates to a method for installing a prefabricated slab for construction of a preassembled unit, in particular a ballastless track, more particularly a plurality of preassembled units arranged in series. And a polygonal point for determining the outer geometry of the course of the segment, and also for prefabricated units, in particular for the construction of a ballless trajectory. It relates to a measuring device comprising a plurality of V-shaped measuring pieces disposed on the slab.

From European Patent Publication No. 0 780 514 B1, a method is known for precisely positioning assembly devices in space, whereby reference points are used so that the rail fixture is placed in the desired position with the desired precision. The assembly device may change a position and may include at least one reference point at a position selected according to a measurement technique. The placement of the rail fixture is controlled in accordance with the position relative to the reference point from the assembly device. In this regard, sensors are formed on the assembly apparatus to detect the height position of the assembly apparatus in comparison with the height of each corresponding reference point as a TV camera. The deviation of the actual position relative to the nominal position is calculated, whereby the assembly device is adjusted in the longitudinal and transverse directions and displaced into the nominal position. Then, the position of the rail fixture is determined and fixed.

It is undesirable in the apparatus that a plurality of reference points are required to perform the positioning of the rail fixtures with the precision required in high speed railways when the rail fixtures are installed correctly.

The reference points should be arranged along the section so that the assembly device is ready for the section. Therefore, a large amount of work is required to form the reference points. In addition, although the proposed method can accurately determine the position of the assembly device, it is not possible to check whether the assembly device correctly positions the rail fixture.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a method and an apparatus which makes it possible to quickly and reliably install a pre-assembled slab, especially at a low labor cost, while avoiding the above mentioned disadvantages. will be. Still another object of the present invention is to make it possible to use simple and standardized measuring instruments for precise measurement and for the installation of pre-assembled units.

This object is achieved by the features of the independent claims.

The method according to the invention is used to install a pre-assembled unit, more specifically a pre-assembled slab for constructing a ballless track. A plurality of pre-assembled units arranged in series form one section. The section consisting of the pre-assembled units includes polygonal points that determine the outer geometry of the course of the section. According to the invention a measuring device, in particular a tachymeter, is provided at the first polygonal point, oriented in consideration of at least one target point, to form an extension in the longitudinal direction to the section guide line, and then the preassembly The measuring points of the assembled unit are measured relative to the guide line to determine the actual position of the pre-assembled unit, the actual position being compared to the nominal position. The preassembled unit is then installed according to the difference between the actual position and the nominal position. The actual position measurement of the orientation of the tachymeter and the measuring point of the preassembled unit is achieved by providing a target line or an alignment line between the tachymeter and the target point. In this regard the position of the measuring point is detected starting from the target line or the alignment line. To this end, the distance between the measuring line from the tachymeter as well as the angle between the alignment line and the line between the tachymeter and the measuring point is detected and compared with a nominal value. If the nominal value does not match the required actual value, the position of the pre-assembled unit is corrected. In contrast to the few polygonal points that determine the outer geometry of the interval course, the target lines of the few pre-assembled units are components of the inner geometry of the interval course. In other words, the target lines determine the neighborhood precision of the pre-assembled units arranged in succession.

Preferably, polygonal points close to the center portion in the width direction of the section are selected. Polygonal points close to the center in the width direction as described above are parameters of the internal geometry that must be maintained in relation to their adjacent precision. In other words, adjacent polygonal points should only have a particularly small deviation from the required internal geometry. Overall, the polygonal points represent the outer geometry of the interval and can allow for greater tolerance in this regard. The magnitude of the tolerance that can be achieved immediately using the measuring system of the present invention is about +/- 0.2 mm in terms of adjacent precision or internal geometry for pre-assembled units for constructing a ballless trajectory. Polygonal points proximal to the lateral center preferably reflect the outer geometry of the segment, thus enabling the practical installation of the segment on the axis determined by the polygonal points.

Preferably, the measuring points are measured taking into account the position of the line between the tachymeter and the target point. An important part of this is the distance between the tachymeter and the measuring point and the angle between the target line and the line from the tachymeter to the measuring point. When measuring the distance between the tachymeter and the measuring point, a tolerance of about +/- 1mm is not important when installing a ballless track. Instead of the angular deviation from the target line, the lateral deviation of the target line may also be considered to determine the precision of the measurement point. This can often be a better and easier way to determine the position of the measurement point. In this case a tolerance of +/- 0.1 mm can be tolerated.

Using this tolerance, the position of the pre-assembled unit or its measuring point is provided from the nominal line, in other words with very high precision with respect to the internal geometry. Thereby the curvature between the minority intervals determined by the pre-assembled unit is particularly minimal. By this, the pre-assembled units are assembled very accurately. Therefore, the driving of a high-speed train on pre-assembled units of a ballless track is very pleasant and safe.

The measuring points of the pre-assembled unit are preferably V-shaped measuring pieces which are arranged in the pre-assembled unit. The V-shaped measuring pieces can be seated on the pre-assembled unit and thus indirectly indicate the position of the pre-assembled unit, for example using a gauge that simulates the upper rim of the rails or the pre-assembly. It can be arranged directly in the assembled unit and thus direct the position of the pre-assembled unit.

A particularly preferable case is when a V-shaped measuring piece disposed at a polygonal point is used as a target point. The V-shaped measuring piece is particularly suitable for aiming through a measuring instrument or tachymeter. If the V-shaped measuring piece is arranged at a polygonal point, the line between the tachymeter and the polygonal point forms an alignment line or a target line in which the pre-assembled unit is positioned. When accurately positioning a small number of polygonal points, the tachometer and the V-shaped measuring piece corresponding to each polygonal point, a sufficiently accurate target line is provided that allows the installation of a pre-assembled unit having only a slight bend.

If the target point is set in a precisely adjusted, preferably finally precisely pre-assembled unit, the installation of pre-assembled units that are arranged more continuously in succession than if the target point is placed at a polygonal point It is possible. Therefore, the inaccuracies that may occur in the placement of the finally assembled preassembled unit are compensated for. Therefore, the actual internal geometry is further smoothed.

Preferably the pre-assembled unit is supported on the road surface by means of an adjustment member, more particularly by means of a spindle, and more particularly on a hydraulically coupled support layer (HGT). By rotating the spindle the pre-assembled unit is placed in the nominal position corresponding to the preset value at the time of measurement.

If the adjusting member, in particular the spindle, is screwed onto the road surface before measuring its actual position, the predetermined position of the spindle and the pre-assembled unit is provided, starting from the predetermined position and the pre-assembled unit You can run the installation of.

A particularly simple case is when the spindle is fixed at a predetermined torque on the road surface. As soon as the torque is applied to the spindle or screw, a predetermined position of the spindle and the pre-assembled unit is obtained, followed by adjustment of the pre-assembled unit from the predetermined position. In order to further ensure safety during the fine adjustment of the pre-assembled unit, the difference between the actual position and the nominal position is preferentially indicated and preferably removed before the pre-assembled unit is actually installed. This avoids the point where, when an inadequate measurement is made, the preassembled unit is inadequately installed and a completely new measurement and installation of the preassembled unit is to be carried out. Probability checks can be carried out on the display and, in some cases, new measurements can be taken.

If the spindle is adjusted using an automatically controlled adjustment screw, it is possible to install a pre-assembled unit very quickly and reliably, saving labor.

Especially simple and preferably, the measurement of the said measuring point is performed automatically. The tachymeter automatically performs the detection of the actual position at every measuring point, and then displays the adjustment or control data of the adjusting member, in particular the spindle, using a display device. The user no longer has to manually aim the few measuring points.

After detecting the actual position, and after calculating the difference compared to the nominal position, the installation of the pre-assembled unit takes place in particular through the adjustment of the adjusting member, in particular the spindle. The measuring points are newly measured and compared with the corresponding nominal positions. If the difference is outside the allowable tolerance, the fine adjustment process is repeated until the difference between the actual position and the nominal position no longer exceeds a pre-specified value.

The final measurements of the fine adjustment process are preferably stored as a measurement protocol so that the position of the pre-assembled unit can be documented and optionally presented as evidence to the contractor.

The apparatus according to the invention which can be used in carrying out the method according to the invention for installing a pre-assembled unit comprises a plurality of devices provided for placement in a pre-assembled unit, and above all, a pre-assembled slab for ballless track construction. It includes a measuring device including the V-shaped measuring pieces. The apparatus of the invention comprises V-shaped piece carriers spaced apart from each other in the longitudinal direction of the measuring device. Each of these V-shaped piece carriers is spaced at a predetermined position of the pre-assembled unit or at a predetermined interval relative to the pre-assembled unit when the apparatus of the present invention is disposed on the pre-assembled unit. At least one V-shaped measuring piece is fixed to the position.

The device of the invention particularly preferably provides mutual assignment of a few V-shaped measuring pieces, in particular when there are a plurality of V-type measuring pieces, and thus mutual adjustment of the V-shaped measuring pieces in the precise adjustment of the pre-assembled unit. No longer require. The device of the present invention forms a so-called gauge for installing a pre-assembled unit. In this regard, the V-shaped measuring pieces are located at predetermined positions with respect to the pre-assembled unit, and thus can be retained even when measuring any number of pre-assembled units. After installing the preassembled unit, the device of the invention is removed from the preassembled unit and moved onto the immediately following preassembled unit. After moving, the device only needs to roughly position in order to provide a target point for the measurement of the pre-assembled unit.

Preferably the V-shaped measuring piece of the device of the invention is arranged in the region of the support spindle of the pre-assembled unit. The value measured on the V-shaped measuring piece can thereby be converted directly to the adjustment of the support spindle. Thus, when adjusting the spindle by a specified value, the position of the V-shaped measuring piece can also be changed by the value. Therefore no further conversion is necessary.

If the V-shaped measuring piece is arranged in the region of the rail support point, the support point of the rail can thus be measured on the pre-assembled unit of the ballless track. In this case, the V-shaped measuring piece may be directly seated on the rail support point or may be disposed at a position spaced apart from the rail support point by a predetermined distance in accordance with a particularly preferred embodiment, so that the V-shaped measuring piece is, for example, It may correspond to the spaced distance of the upper rim of the rail from the preassembled unit.

By arranging the V-shaped measuring piece spaced at a defined interval from the pre-assembled unit, a later installed rail is simulated and oriented toward a point important for the driving operation of the train.

If at least two V-shaped specimens are arranged on the V-shaped specimen carrier, representing the mutual spacing of two parallel rails, the pre-assembled slab is oriented corresponding to the rail course. This ensures particularly comfortable driving of the train vehicle, since shocks are avoided. This arrangement also compensates for the height difference at the surface of the pre-assembled unit near the spindle, thereby providing a uniformly formed rail course.

Particularly preferably with regard to the measurement and positioning of the device of the invention the V-shaped piece carrier comprises a device for a V type piece, which device can be seated on a rail support and thus from the rail support Corresponds to the spaced interval of the negative. Therefore, the V-shaped measuring piece device limits the range of the rail head portion within a predetermined distance from its bearing point. In this case the foundation, which is arranged under the rail bottom in the form of a rubber sheet, for example, can be considered together if the spacing is corresponding thereto.

In order to continuously measure a plurality of pre-assembled units, the device according to the invention is particularly preferably displaced on the pre-assembled unit. To this end, wheels which can be displaced onto the pre-assembled unit, which, for example, guide the device of the invention on the pre-assembled unit and after installation of the pre-assembled unit, can be connected with the device of the invention. .

If at least one motor actuator is arranged in the apparatus of the present invention for adjusting the support spindle of the pre-assembled unit, the installation of the pre-assembled unit is very quick and simple. When a corresponding signal is applied to the motor actuator, the motor actuator operates while rotating the support spindle of the preassembled unit by a predetermined dimension to move the preassembled unit up and down.

Particularly preferably the motor actuators orient the pre-assembled unit not only at the height of the pre-assembled unit but also transversely with respect to its longitudinal axis. The same or another motor actuator can be provided for this purpose, one motor actuator being used for height adjustment of the pre-assembled unit and the other motor actuator being used for its lateral adjustment.

In that it is preferably provided for automatically adjusting the position of the pre-assembled unit, the motor actuator is controlled via a computer or through an evaluation device of a tachymeter. In this regard the measurements obtained from the tachymeter can be transmitted directly to the motor actuator via a control device, thereby acting so that the pre-assembled unit can be adjusted accordingly to its nominal position.

Using a bank sensor, measurement is preferably carried out in conjunction with three V-shaped measuring pieces arranged in succession, thereby determining the position of the pre-assembled unit alternately.

Further advantages of the invention are explained in more detail according to the following examples in conjunction with the drawings.

1 is a plan view of a measuring device.

2 is a cross-sectional view cut away of a pre-assembled slab comprising a measuring device.

3 is a plan view showing a further measuring device.

Figure 1 shows a plan view of a measuring device arranged in three successively arranged slabs 1, 1 ', 1 "of a ball-free track for a rail guide vehicle. The prefabricated slab 1, Each 1 ', 1 ") has rail supports 2, and after installing the pre-assembled slabs 1, 1', 1", the rail guide vehicle rails are mounted on the rail supports. FIG. The pre-assembled slab 1 partially shown on the left side of is located in its nominal position, whereas the pre-assembled slabs 1 'and 1 "on the middle and right are still in the state of installation. 1 shows the installation of the intermediate prefabricated slab 1 ′.

Polygonal points 3 or 3 'are arranged between the preassembled slabs 1. The polygonal points essentially represent the outer geometry of the driving segment. The inner geometry inside the outer geometry, which may have a relatively large deviation from the nominal geometry, ie is provided from a plurality of pre-assembled slabs 1, 1 ′, 1 ″ which are arranged adjacently adjacent. The polygonal course should be as uniform as possible in order to make the driving of the vehicle particularly comfortable.

The polygonal point 3 is located between the pre-assembled slab 1 which is almost completely installed and the pre-assembled slab 1 'to be installed. The polygonal point is used as a reference for the tachometer 4 for installing the pre-assembled slab 1 '. The tachometer 4 is located on the polygonal point 3 'for installing the pre-assembled slab 1'. For orientation of the tachymeter 4, the tachymeter 4 aims the beam on a target Vblock 5 located on the polygonal point 3. By doing so, an alignment line 6 is formed between the tachymeter 4 and the target V block 5, and the pre-assembled slab 1 ′ is positioned according to this alignment line.

On the pre-assembled slab 1 ′ a measuring device 10 is situated. Six V-shaped measuring pieces 11.1 to 11.6 are disposed in the measuring device 10. The V-shaped measuring pieces 11.1 to 11.6 are located at the support points 2 of the pre-assembled slab 1 '. In addition, the V-shaped measuring pieces 11.1 to 11.6 are located close to the spindle 12 provided for adjusting the pre-assembled slab 1 '. The spindle 12 is adjusted somewhat broadly using a motor actuator 13 which rotates the spindle 12 along the thread and thus raises and lowers the pre-assembled slab 1 '.

Deviation of the few V-shaped measuring pieces 11.1 to 11.6 starting from the alignment line 6 to measure the actual position of the pre-assembled slab 1 'is detected using the tachometer 4. . For this purpose, the distance of the few V-shaped measuring pieces 11.1 to 11.6 is measured by the tachometer 4 as well as the measuring beam (1) between the alignment line 6 and the few V-shaped measuring pieces 11.1 to 11.6. An angle α between 14.1 and 14.6) is detected. The resulting values are compared with a predefined nominal value. If the two values are within the tolerance, the pre-assembled slab 1 'is installed as it is. If not within tolerance, each spindle 12 is actuated by a signal applied to the motor actuator 13 to change the position of the pre-assembled slab 1 '. Subsequently, a measurement for the V-shaped pieces is newly started and the measured value is compared with the nominal value. This is done until the nominal and actual values are within the tolerance range.

If the installation of the pre-assembled slab 1 'is completed, the measuring device 10 is moved to the new pre-assembled slab 1 "which is separated. This is the polygon that the tachometer 4 follows immediately after. The target V-block 5 is seated on the polygonal point 3 'and the measuring device 10 is mounted from the pre-assembled slab 1' to the pre-assembled slab 1 '. ") Is moved onto. To this end, the measuring device 10 comprises wheels 15 which are able to move on the pre-assembled slabs 1 ′ and 1 ″. To ensure the track movement safety of the measuring device 10. To this end, the measuring device, together with the wheels 15, is side fixed to the preassembled slab 1 ′ and thus centers the measuring device 10 on the preassembled slab 1 ′. It is further provided with support wheels 16. The measuring device 10 is then positioned on the pre-assembled slab 1 ", so that the motor actuator 13 is attached to the spindle 12. And the spindle 12 can be rotated to position the slab 1 ". The measuring procedure for installing the prefabricated slab 1" is then carried out by the slab 1 '. Run in the same way as

In the alternative or addition to this measurement, only one directional line is measured, ie a series of V-shaped pieces, i.e. V-shaped pieces 11.2, 11.4 and 11.6 or V-shaped pieces 11.1, Measurements can be made only for 11.3 and 11.5). In this connection, as further measurement values, values of the lateral inclination sensors 110 are used starting from the measured V-shaped measurement piece to indicate the lateral inclination of the slab 1 '. By doing so, a fairly accurate detection of the position of the pre-assembled slab 1 'can be achieved. Said lateral tilt sensors, also referred to as inclinometers, are arranged, for example, on a braced link of the measuring device 10. The required adjustment of the spindle 17 can be achieved in conjunction with the values of the V-shaped measuring piece from the signals of the sensors.

2 shows a cross section of a pre-assembled slab 1 ′ disposed on a support layer 20 hydraulically fastened using a spindle 12. Spindle 12 supports the prefabricated slab 1 ′ on the upper surface of the support layer 20. Within the support layer 20 a polygonal point 3 ′ is arranged which limits the external geometry of the section course. The tachymeter 4 is arranged at the polygon point 3 '. The tachymeter 4 sends the measuring beams 14.1 and 14.2 on the V-shaped measuring pieces 11.1 and 11.2. The position of the pre-assembled slab 1 'is determined from the position of the V-shaped measuring pieces 11.1 and 11.2 relative to the nominal position.

The V-shaped measuring pieces 11.1 and 11.2 are located in the measuring device 10. The V-shaped measuring pieces are arranged on the support points 2 of the pre-assembled slab 1 'using the bottoms 21 (foot). The bottoms 21 simulate a trajectory that will later be mounted on the support points 2. Therefore, the V-shaped measuring pieces 11.1 and 11.2 are positioned at a height corresponding to the subsequent rail head portion. In order to take into account the track width when measuring the pre-assembled slab 1 ′, the two V-shaped measuring pieces 11.1 and 11.2 are connected with a connecting rod 22.

The measuring device 10 is equipped with wheels 15 in order to transfer the arrangement of the measuring device 10 from the pre-assembled slab 1 where the installation is completed to the newly assembled pre-assembled slab 1 '. The bottoms 21, the connecting rods 22 and the motor actuators are arranged in the measuring device 10. Accordingly, the measuring device 10 can be moved very quickly and without incurring a large labor cost.

FIG. 3 basically corresponds to the measuring method of FIG. 1, but shows a measuring method that is more accurately applied when considering the internal geometry. The determination of the alignment line is made without measuring the polygonal point 3 proximate to the pre-assembled slab 1 already installed. Rather the alignment line 6 ′ is adjusted to the point on the pre-assembled slab 1 which is already correctly installed. For this purpose an auxiliary device 25 comprising a target V block 5 ′ is arranged on the support point of the pre-assembled slab 1. The tachometer 4 is then oriented in the target V block 5 ', thereby creating two alignment lines 6'. The V-shaped measuring pieces 11.1 to 11.6 are measured starting from the alignment lines 6 '. Inaccuracies existing between the polygonal point 3 and the prefabricated slab 1 'actually arranged are eliminated by the installation method, since the actual preassembled slab 1 already installed has an important meaning. Because.

A further difference of the measuring method compared to the measuring method according to FIG. 1 is that the tachometer 4 is not located at the polygon point 3 closest to it, but at a farther away polygon point 3. Is that it is. This results in longer measurement beams, which make the measurement more accurate and reduce measurement errors. The preassembled slab 1 'can thus be installed more accurately.

The invention is not limited to the illustrated embodiments. More specifically, the invention may be formed by combining the embodiments of the present invention shown in FIGS. 1 and 3. Thus, for example, the tachymeter 4 can be arranged closer to the pre-assembled slab to be installed than in the case shown in FIG. Besides, it is not necessary to set the spindle 12 using the motor actuator 13 in each case. Naturally, the spindle 12 can be adjusted manually. In addition, in most cases, it may be sufficient to perform height adjustment using only the spindle 12. Lateral adjustment of the pre-assembled slab using the spindle 17 and optionally the motor actuators 13 connected thereto is not always required. The preassembled slab may also be adjusted via corresponding adjustment devices. It is also possible to use another adjusting member having the same function instead of the spindle. For this purpose it is also possible, for example, to use hydraulic or pneumatic cylinders to move the pre-assembled slab to the desired position. Therefore, the protection scope of the present invention includes up to the adjustment members.
