Definitions

  • the invention relates to a machine with a machine frame that can be moved on trolleys and at least one work unit connected to it and adjustable by adjusting drives relative to the machine frame for producing a target track position and a measuring unit having a laser transmitter of an absolute measuring system for detecting geodetically measured, defining the absolute track position .
  • Patent application WO 93/06303 a measuring platform that is movable on the track and coupled in front of an maintenance machine with a laser transmitter is known, which can be aligned to the fixed points defining the absolute track position.
  • a space-stabilized gyro platform also mounted on the measuring platform determines the absolute change in position of the measuring platform, which serves as a correction of the angle change values of the laser transmitter.
  • the distance traveled is determined either with a separate odometer or using the gyro platform.
  • the current position with reference to fixed points determined from this data is compared with the target value of the measurement plan and, if necessary, the track is corrected on the basis of these values.
  • CH 684 026 A5 describes a method for measuring relative angles between a reference direction of a measuring platform and fixed points distant therefrom by means of light rays emanating from the measuring platform. These are reflected back to the measuring platform by means of reflection means attached to the fixed points and received and processed by receiving means provided on the measuring platform.
  • the object of the present invention is to create a machine of the generic type with which the track position can be optimized, in particular in connection with a renewal of the ballast bed and / or the track.
  • the measuring unit is arranged directly on the machine frame or on a work unit and is connected to a control device which is designed to act upon the adjustment drive for controlling the work unit according to at least one parameter from the group: altitude, side position, bank angle is.
  • Such training is particularly suitable for those machines in which the position of the track section located in front of the machine in the working direction cannot be used as a relative measuring base, since the track is raised by working units and thus its position is completely changed, exchanged or the ballast bedding is renewed .
  • it is now possible for the first time to position the new track position according to fixed points in a target position even with such track construction machines.
  • a track construction machine 1 for dismantling an old track 2 and laying a new track 3 can be seen, a rail expansion wagon following in the working direction for supporting new rails 18 on new sleepers 14 not being shown for the sake of a better overview.
  • the arrow 4 which can be moved continuously according to the working direction, has a machine frame 5 which is supported on the old track 2 at its front end in the working direction by a rail carriage 6, while the rear end of the machine frame 5 is connected to a height-adjustable crawler chassis 8 which has its own travel drive 7.
  • Another rail running gear 9 provided for the transfer run is pivoted up into an out-of-service position during work.
  • the crawler chassis 8 is immediately preceded by a sleeper receiving device 10, which is assigned a first conveyor 11 for removing old sleepers 12.
  • a second conveyor device 13 for the transport of new sleepers 14 ends in the area of a sleeper laying device 15 arranged behind the crawler track 8.
  • the machine 1 is further equipped with height and side adjustable rail guides 16 for the old rails 17 and new rails 18 as well as with work cabins 19 positioned in the work area.
  • a leveling device 20 is provided directly behind the latter.
  • This has a dozer blade 21 extending in the transverse direction of the track (see FIGS. 2 and 3).
  • holders 22 are provided, in which a screw conveyor 23 immediately upstream of the dozer blade 21 is fastened in order to convey pent-up ballast to the side.
  • a compacting device 25 equipped with vibrators 24 is provided in the area between the sleeper laying device 15 and the dozer blade 21.
  • the constructional unit formed from the screw conveyor 23, the dozer blade 21 and the compacting device 25 is articulated to the machine frame 5 via a support frame 26 and is height-adjustable relative to the machine frame 5 by means of adjusting drives 27.
  • the construction unit mentioned can be rotated relative to the support frame 26 about an axis 28 shown in FIG. 2, so that a desired transverse inclination of a bedding surface 29 compressed by the compacting device 25 can be produced regardless of the position of the machine frame 5.
  • the threshold laying device 15 is pivotally mounted about a horizontal axis 30 running transversely to the machine longitudinal direction and can also be moved transversely to the machine longitudinal direction with the aid of an adjustment drive 31 (FIG. 3).
  • the transverse displacement can be measured by an electromechanical distance measuring device 32, which here is formed, for example, from a rotary potentiometer attached to the machine frame 5, which is connected to the threshold laying device 15 by a cable.
  • the sleeper laying device 15 and the compacting device 25 are referred to here in a superordinate term together as working units 33, each of which is a part of the common task of producing a desired track position.
  • the machine 1 is equipped with a measuring system 34 for determining the absolute or the desired track position.
  • This measuring system 34 essentially consists of a measuring unit 36 having a laser transmitter 35 and a control device 37.
  • a measuring unit is already known from WO 93/06303 or CH 684 026 A5 and is described in detail, so that there is no need to go into detail about the mode of operation.
  • the control device 37 is designed to act on the adjusting drives 27 and 31 and is connected to the distance measuring device 32 and to two laser transmitters 39 which are arranged at a distance from one another in the cross-machine direction and are combined with a receiver. These are attached to the machine frame 5 and are provided for distance measurement.
  • the laser beam is reflected by target reflectors 40 which are fastened on the compacting device 25.
  • Measuring unit 36 displays the target cross slope, which in this simplified example lies horizontally, that is, the target cross slope has the value zero.
  • the gyro platform 41 now offers the possibility of measuring the relative position to the machine frame 5 in all three axes, namely the orientation with reference to the north, and the horizontal and vertical position.
  • the relative position of the machine frame 5 must be disregarded in this exemplary embodiment and rather the relative position of the compacting device 25 the gyro platform 41 are referred. This is done by detecting the distance between the machine frame 5 and the two target reflectors 40 with the aid of the two laser transmitters 39. In the simplified example, both target reflectors 40 are located exactly in a target track plane 42 defined by the fixed points 38 and determined by the measuring system 34.
  • the compacted bedding surface 29 comes to lie precisely in the height position which, after the new sleepers 14 have been deposited and the new rails 18 have been placed, ensures that the track is at a desired bank angle and at a desired height.
  • the relative measurement between the gyro platform 41 and the position of the compacting device 25 results in a shortfall, i.e. a bank error
  • one of the two adjusting drives 27 is acted upon by the control device 37, for example, until the two target reflectors 40 in the desired track plane 42 come to rest.
  • the set altitude is regulated in parallel by appropriately acting on the adjustment drives 27.
  • a necessary lowering of the bed surface 29 could also be achieved or supported by increasing the frequency of the vibrators 24.
  • the bedding surface 29 - regardless of the position of the machine frame 5 - is in that absolute position which, after the new sleepers 14 and new rails 18 have been deposited, a desired track position results.
  • the control with respect to the desired lateral position of the new track 3 is carried out by a corresponding transverse displacement of the sleeper laying device 15 relative to the machine frame 5 by acting on the adjustment drive 31.
  • the required transverse displacement corresponds to the difference between the nominal lateral position determined by the measuring system 34 and one expediently by a central position of the threshold laying device 15 with respect to the width of the machine frame 5 defined zero position of the threshold laying device 15 (see line 43 in Fig. 3).
  • the corresponding transverse displacement of the threshold laying device 15 into the desired lateral position can be registered by the distance measuring device 32.
  • the value for the nominal lateral position in dependence on one is determined in the area of the compacting device 25 when determining the height, lateral position and transverse inclination to deliver the corresponding distance measurement with a time delay to act upon the adjustment drive 31.
  • a track construction machine 45 which is only partially shown in FIG. 5, has a clearing unit 46 fastened on a machine frame 5, which is guided around a track 47 as a rotatable endless chain for picking up ballast.
  • the ballast picked up by the clearing unit 46 is fed via a conveyor belt 48 to a screening system (not shown) for cleaning.
  • the cleaned ballast is dropped onto the track 47 via a further conveyor belt 49.
  • two track lifting devices 50 arranged one behind the other in the machine longitudinal direction are provided for lifting the track 47.
  • both the clearing unit 46 and the track lifting devices 50 can be referred to as working units 33.
  • a measuring unit 36 formed from a space-stabilized gyroscopic platform and a laser transmitter is attached directly to the rearmost working unit 33 with respect to the working direction or to the second track lifting device 50 and forms a measuring system 34 together with the control device 37.
  • the desired track position is determined, according to which adjustment drives 51 carry out a corresponding relative transverse and height adjustment of the working unit 33 with respect to the machine frame 5, in order to thereby place the track 47 connected to the track lifting device 50 in the desired position on the ballast bed.
  • the cleaned ballast can be leveled and compacted before laying the track 47 - similar to the first embodiment.
  • FIG. 6 shows, in a greatly simplified form, a machine 52 for producing a base layer 53 or a trough made of concrete or asphalt.
  • the machine 52 essentially consists of a machine frame 55 supported on crawler tracks 54, a container 56 for storing concrete or asphalt and a work unit 57. This is designed as a vibrating and leveling device and is connected to the machine frame 55 in a height-adjustable manner by means of drives (not shown).
  • a measuring system 34 is connected to the machine frame 55, which is composed of a rotatable laser transmitter 35, a measuring unit 36, a control device 37 and a laser transmitter 39 for distance measurement.
  • this measuring unit 36 there is the possibility of controlling the working unit 57, as well as the compacting device 25 in FIGS. 1 to 3, in such a way that a track to be laid on the supporting layer 53 comes to lie exactly in the desired target position.
  • the crawler tracks 54 could also be influenced by the measuring system 34, so that the base layer 53 also runs in the desired target range with respect to lateral position.
  • a subsequent track laying machine for laying a track on the base layer 53 would be a sleeper laying device to be controlled as a working unit with the aid of a further measuring unit 36 in such a way that the track also lies in the desired target position with respect to lateral position.
