Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a machine for correcting a track position, and has a machine frame supported by a platform and provided with a reference system for detecting a track target position. And a track lifting unit that can be adjusted in height and laterally by a drive unit.
[0002]
[Prior art]
According to Austrian Patent No. 390288B, such a machine for correcting the track position associated with forming a stationary lane is already known. Such a machine can travel on a track previously laid on a concrete foundation directly by a track laying machine via a rail platform. A track lifting unit is located in the middle between both rail platforms and is used to lift the track to the target position. Immediately after the track lifting unit, a screw unit that can roll on the rail is provided, and the screw spindle mounted in the sleeper is rotated by using the screw unit, and the screw spindle to the concrete foundation is rotated. The sleepers are fixed at the target position by the contact. Then, in the subsequent work process, concrete is poured around the sleepers at the target position. In advance, the machine must be able to run on a track that has already been corrected, on a track section that has already been modified.
[0003]
GB 2257189B describes a machine for correcting the position of a track mounted on a stationary support layer. This machine is provided with three wheel unit support portions arranged in the longitudinal direction of the machine. During the transfer run, the rail carriage is located in the front or rear wheel unit support. When the work is introduced, the rear traveling platform is attached to the intermediate wheel unit support. This allows the track to be lifted to the target position without interruption using a track lifting unit positioned in the end region at the rear of the machine and fixed in place by means of a screw spindle. Such a special structure avoids supporting the machine on a track that has already been adjusted to the target position.
[0004]
EP 0 379 148 B1 discloses a method for forming a ballast-free track superstructure, in which case the tracks are built parallel to each other and in the track longitudinal direction (Beton). -Randbalken) is positioned in a concrete trough. Concrete and edge girders are configured to be loadable by a track laying machine (Gleisbaumaschine) supported on both edge girders after hardening. In addition, a device is also described that separates the track for casting a concrete plate. Such a device is run along a track using a rail platform and is supported on both edge girders via a support beam during the track lifting process. Next, concrete is poured into the sleeper section using a machine that can travel on the edge girder by the endless track platform.
[0005]
From German Patent No. 4328668C1 and German Patent Publication No. 4324301A1, a method and a machine for forming a stationary lane are known.
[0006]
[Problems to be solved by the invention]
The object of the present invention is to improve a machine of the type mentioned at the outset so that the track is moved to the correct target value, avoiding adverse effects in order to form a stationary lane.
[0007]
[Means for Solving the Problems]
In order to solve the above-described modification, in the configuration of the present invention, another second track lifting unit whose height can be adjusted by the drive unit is provided in front of the track lifting unit in the working direction, and the carriage is outside the rail. It is comprised so that it may drive.
[0008]
【The invention's effect】
With the configuration according to the present invention, the track is lifted to the target position step by step regardless of the position of the traveling platform and the interval between the traveling platforms. This avoids stress effects due to trajectory lifting on the trajectory segment already at the target position. Furthermore, also in the region of the first track lifting unit, the auxiliary means used for fixing the position of the track, such as a screw spindle, are lightened. In addition, as an advantage with the arrangement according to the invention, the track is not loaded by the machine weight before or after adjustment to the target position. Therefore, it is possible to reliably eliminate the influence of the already corrected trajectory section on the trajectory position accuracy.

DETAILED DESCRIPTION OF THE INVENTION
The machine 1 shown in FIGS. 1 and 2 has a machine frame 3 supported on a traveling platform (Fahrwerk) 2 for loading the drive unit 5 and all other drive units. The engine (Motor) 4 is arranged. One cockpit or cab 7 is arranged at the front machine end in relation to the center between both platform 2 and the working direction (arrow 6). A reference system (Bezugsystem) 8 for the orbital position correction (Gleislagekorrektur) is arranged on the rail 10 of the orbit 11 and is arranged substantially apart from the chord material (Sehne) 9 extending in the machine longitudinal direction and in the machine longitudinal direction. It consists of three measuring axes (Messachse) 12.
[0010]
A first track lifting unit (Gleishebeaggregat) 14 that can be height-adjusted and laterally adjusted by a drive unit 13 is disposed between the two platforms 2. The track lifting unit includes a lifting roller 15 and a lifting hook 16 for bringing the rail 10 into formschluessig, and a roller 17 with a track guide flange for rolling along the track 11. It is arranged.
[0011]
A second track lifting unit 18 is arranged at the front machine end in front of the front platform 2 and is connected to the machine frame 3 by a drive 19 and a pivot rod 50. . As shown in FIG. 2 in particular, the second track lifting unit 18 is provided with two lateral guide rollers 21 that are separated from each other in the transverse direction of the machine and that are rotatable about a vertical axis 20. It is installed. The side guide roller has a circular rolling line (Abrollinie) 22 located in a plane perpendicular to the shaft 20, and the rolling line is in the vertical direction and the mounting point (Aufstandspunkt) of the carriage 2. ) 23 is arranged on the lower side of the mounting surface 24 defined by. Between the two lateral guide rollers 21 arranged apart from each other in the machine lateral direction, two height direction guide rollers (Hoehenfuehrungsrolle) 26 that are rotatable about a shaft 25 extending in the machine transverse direction and horizontally are arranged. Has been. The distance between both height guide rollers 26 corresponds to the distance A between the two side walls 27 of the concrete trough 28 extending parallel to each other and in the longitudinal direction of the track. A track lifting device 29 for gripping the rail 10 is disposed in the second track lifting unit 18 between the height direction guide rollers 26. The concrete trough 28 rests on a concrete foundation 30 and forms an immovable lane 32 together with a track 11 composed of rails 10 and sleepers 31.
[0012]
Each platform 2 consists of two endless track platforms (Raupenfahrwerk) 33 that are separated from each other in the transverse direction of the machine and can be loaded by the traveling drive unit 5. Each endless track platform 33 that is rotatable about a vertical axis is provided with a guide roller 35 that is rotatable about a vertical axis 34. Like the side guide roller 21, the guide roller 35 has a circular rolling line 36 located in a horizontal plane, and the rolling line is a mounting surface 24 defined by the mounting point 23. Located on the underside. As can be seen in particular from FIG. 2, the cross-machine spacing between both shafts 34 corresponds to the maximum width of the concrete trough 28 increased by the diameter of the guide roller 35.
[0013]
A screw head 40 that can be rotated by the drive unit 39 and can be adjusted in height is provided between the first track lifting unit 14 and the following platform 2 in the working direction, and the height is adjusted by the drive unit 37. Screw unit pivotally attached to the machine frame 3 (
Schraubaggregat) 38 is provided. Using the screw head, the adjusting screw 41 (FIG. 2) arranged in the sleeper tip section of the sleeper 31 can be rotated or adjusted in the vertical direction.
[0014]
In the area of the screw unit 38 is arranged an outlet opening 43 of a conduit 44 connected to the machine frame 3 which can be remotely controlled by a valve 42. The conduit is connected to a pump 45 and a tank container 51, and the tank container is connected to the machine 1 and is disposed in a freight car 46 that can also travel on the endless track platform 33.
[0015]
The measuring shaft 12 at the rearmost position in the working direction of the reference system 8 can be rolled along the track by a roller 47 with a track guide flange, and is driven by a drive unit 48 for generating a vertical force on the track 11. Also used as a fixing device 49.
[0016]
The machine 1 is supported on both side walls 27 of the concrete trough 28 exclusively via the endless track platform 33 during work, and is moved from the sleeper to the sleeper by the load of the traveling drive unit 5. In this case, the rail 10 of the track 11 is grabbed by the track lifting device 29 of the second track lifting unit 18 and supports the height guide rollers 26 on both side walls 27 and automatically has a predetermined minimum dimension. It is lifted from the bottom surface of the concrete trough 28 together with the sleepers 31. At the same time, the center of the track 11 with respect to the center of the concrete trough 28 is automatically performed by both side guide rollers 21. The drive unit 19 is not loaded during work.
[0017]
In parallel to this, the first trajectory lifting unit 14 performs another lifting of the trajectory 11 to the target position defined using the reference system 8, in this case possibly with corrections related to the lateral position. Is also performed at the same time. The track 11 that is now at the target position is fixed at this position by attaching the screw head 40 of the screw unit 38 to the adjustment screw 41 and rotating the adjustment screw to contact the bottom surface 52 of the concrete trough 28. Is done. At the same time, the track 11 may be fixed in relation to the lateral position using another adjusting screw (not shown). Synchronously with the lifting of the track 11 by the first track lifting unit 14, the load of the effective drive unit 48 is applied downward in the vertical direction, whereby the roller 47 with the track guide flange of the fixing device 49 is preselected. The rail 10 is adapted by force. Accordingly, the lifting of the track 11 by the first track lifting unit 14 is reliably excluded from affecting the position of the immediately following track segment that is already at the target position.
[0018]
In parallel with the operation of the adjusting screw 41, a plastic material that hardens rapidly, depending on the corresponding load of the valve 42, is formed between the tip of the sleeper and the side wall 27 or between the bottom surface 52 of the concrete trough 28 and the sleeper 31. The space between is filled. Advantageously, the material is initially filled in a small amount exclusively in the area of the second or third sleeper, and in some cases, further orbital position corrections deemed necessary based on the re-measurement process (Nachmessvorgang) can be performed. Subsequently, in the subsequent work process, the solid connection between the track 11 and the concrete trough 28 is performed by filling the concrete.
[0019]
In another use of the machine, a material that rapidly hardens after adjustment beyond the target position by the first track lifting unit 14 without the screw unit 38 and without the adjusting screw 41 is provided by the conduit 44. It is possible to fix the track 11 by filling. It is also possible to travel on the concrete foundation 30 by separating the traveling platform 2 from each other in the machine lateral direction.
