The invention relates to a traveling machine having a frame made with the possibility of movement along the path using the running gears, and to the option of movement along the path by means of rollers with a comb, as well as to a method for the registration provisions of the path.

From EP 0806523 A1 already known such travel by a car or a way to define the preset position to the track. Using laser transmitter measure the position photopolymer unit in contact with the rails relative to the frame of the machine, his own position, which was determined by surveying points, measured by surveyors and determining the absolute position of the path.

From the patent DE 4102871 C2 also known measurement of the track machine displacement measuring axis or in contact with the rails of the device, rolling on the path, relative to the machine frame mounted on the running gear mechanisms on the railway track.

In EP 1028325 A2 describes a method of measuring the track by means of two measuring units of rolling stock, which move along the path independently from each other and which are mounted at the end points of the measured section of the route.

The objective of the proposed invention is to provide a machine or method of the specified type, using which you can quickly and accurately accurately register the position of the track.

According to the invention this task is solved by means of the machine of the specified type, the measuring device for determining the relative position of the center of the antenna relative to the contact rails of the device parameters: the cross slope of the road, the transverse displacement and the vertical distance perpendicular to the longitudinal direction of the machine, and a computer device for determining the displacement of the center of the antenna relative to the base point contact with the rails.

Using the claimed indication is possible, despite the accommodation by car satellite receiver, designed for optimal reception, to ensure exact parallel to the direction of the center of the antenna relative to the track axis.

Other advantages and embodiments of the invention are given in the dependent claims and shown in the drawing.

The invention is explained in more detail below using the example of execution represented in the drawings.

Fig.1 is a side view of the stated track machine having contact with the rails of the device.

Fig.2 is a diagrammatic representation of machine in the longitudinal direction of the track in cross-section according to line II in Fig.1.

Fig.3, 4, 5 - the corresponding chart of the various steps of the claimed method.

Travel machine 1 shown in Fig.1 and 2, has its own frame 2, which is based on track 4 by means running gears 3 and has a driver's cabin or working cab is the possibility of movement along the path 4 regardless of the machine and which produce a measurement of the actual position 4 in the working direction, indicated by the arrow 8 (it is already known from EP 1028325 A2, so here it is in more detail not pointed).

When viewed in the working direction of the machine, the front suspension mechanism 3 of the machine 1 is in contact with the rails of the device 9, which is based on path 4 by means of rollers with a crest 10. It is in contact with the rails, the device 9 is an essentially measuring axis 11, is arranged to move along the path and connected to the machine frame 2 by hinges with swing and associated with the possibility of moving in height by actuators (not represented here), with which the measuring axis 11 to the beginning of the work machine 1 is lowered or put on the rails 12 4. Directly above the contact with the rails device 9 on the frame machine 2 fortified satellite receiver 13, which has an antenna 14 with its center 15 and serves to receive extraterrestrial satellite signals about the position (or signals of global satellite systems radiodetermination). Laser receiver 28 is used together with the laser transmitter 29 for forming the measuring line 30.

On machine 1 is provided, in addition, the measuring device 16, which serves for the registration is that device 16 is a laser scanning device 17, which has a scanning plane 18 passing in the transverse direction of the machine (origin 19), and which is connected with the underside of the machine frame 2. Origin 19 forms an optical center 24 of the measuring device 16, which is installed in the longitudinal direction of the machine above the contact rails of the device 9. On the measuring axis 11 in contact with the rails of the device 9, which is located directly under the measuring device is reading the object 20, which is provided for reading using a laser scanning device 17 in the form of line 21, located in the middle between the rollers with a comb 10 and held in the transverse direction of the machine. It has a base point 22, also located in the middle between the rollers with a comb 10 and having the form of a pin 23 passing in a vertical direction relative to the line 21.

With the help of Fig.3, 4 and 5 is described in more detail that check the position of the center of the antenna 15 for contact with the rails of the device 9 takes place with the following parameters: cross-track gradient, transverse shift path d perpendicular relative to the longitudinal direction machinei with him with regard to these parameters and on the basis of the calculations, manufactured computing device 25 provided on the machine 1, is offset from the center of the antenna 15 relative to the base point 22 in contact with the rails of the device 9. In other words, determine the position of the center of the antenna 15 satellite receiver 13, located on the frame 2 of the machine 1, relative to the base point 22 in contact with the rails of the device 9, is made with the possibility of rolling on the path 4 and associated with the machine 1, so by determining the position coordinates of the center of the antenna 15 with signals about the position (or signals of global satellite systems radiodetermination) automatically register the absolute position coordinates of the path in the area of contact with the rails of the device 9.

In Fig.3 shows the measurement of the inclination of the machine frame 2 relative to the measuring axis 11. Typically, the frame of the machine 2 because of the cushioning running gears 3 will have a different transverse angles than the measuring axis 11, which certainly corresponds to the cross-track gradient. This different transverse gradient is determined using a laser scanning device 17, when set the coordinate system XY, which has a zero mark in the black rays or target points, being outside in the transverse direction of the machine and falls in line 21 can thus be calculated in the coordinate system. From this learn (calculation method) the tilt frame. Since this angle isgives only the relative angle between the frame of the machine 2 and the measuring axis 11, it is necessary to determine the absolute inclination of the frame (relative to horizontal). To do this, measure the transverse tilt measuring axis 11 corresponding to the cross-track gradientusing the placed inclinometer 26. From this valuesubtract the tilt frameto obtain the absolute tilt of the frame.

Fig.4 explains the calculation of the distance and height between the measuring axis 11 and the frame of the machine 2. The laser scanning device 17 whose resolution angle is approximately 0.05gives for each stage the size of the angle and distance relative to the scanned line 21. Thus the pin 23, which forms the base point 22 and extending from the center line 21, by means of a laser scanning device 17 can uniquely identify or determine its horizontina as horizontally, and vertically between the frame of the machine 2 and the measuring axis 11. To find a base point, from remote measurements of the laser scanning unit 17 selects the measurement result, which has the smallest distance in the Central area. This measurement result is distance and anglein the coordinate system in which the frame of the machine forms the X axis, and the reference point is at the origin 19 laser scanning device 17. Thus a base point 22 is determined in the coordinate system on the basis of these values and.

As first specified coordinate system changes the position after deflection of the frame from horizontal, the entire coordinate system to calculate the height and distance horizontally from the zero mark should be rotated even when the calculation following the deviation of the frame in horizontal position.

In the circuit of Fig.5 given the significant parameters of the proposed method of measurement. When commissioning the machine 1 or before commencement of work will receive the following constants:

h = the vertical distance from the center of the antenna 15 satellite receiver 13 to the origin 19 laser scanning device;

d = rasstrojstva 17;

b = the distance between the inner edge of the rail 12 and the base point 22 on the line 21 and

C = the vertical distance between the line 21 or the base point 22 and the top edge of the rail 12.

Described using Fig.3 and 4 measurements and calculations give the following values:

= relative lateral tilting of the machine frame 2;

= cross slope of the track 4, the corresponding transverse tilt measuring axis 11;

= the angle at which the laser scanning unit 17 recognizes the pin 23 or the base point 22;

a = the distance between the origin point 19 of the scanning device and the reference point 22 on the line 21, the measured laser scanning device.

From the totality of these data define then by computing the distance vertically and horizontally between the antenna global satellite radiodetermination system 14 and the contact point of the contact device 9 with the rail 12.
