  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve a device and method of the type described at the beginning, and to efficiently convert a conventional general track into a solid traveling path under continuous work progress. Is to provide a device.

  In order to solve the above problems, in the method of the present invention, a) the track is lifted under the formation of the work section, and b) the ballast of the ballast roadbed is formed in the work section under the formation of the roadbed during continuous work advancement. C) Gravel supplied to the mixer device is mixed with a binder, dropped onto the roadbed, leveled and compacted under the formation of the support layer, d) The lifted rail is continuously advanced It was laid on the support layer below. Furthermore, in order to solve the above-mentioned problems, in the configuration of the present invention, one of the working vehicles equipped with a clearing chain for accommodating ballast, a mixer device for mixing gravel with a binder, and a track lifting device. A ballast wheel for storing the stored ballast is disposed at the end of the gravel, and a gravel wheel having gravel is disposed at the other end.

  Due to the method steps according to the invention, this is the first step which can be carried out relatively easily in order to convert a conventional ordinary track in the direction of a rigid path in the frame of a continuous machine advance. This is possible without the need to dismantle the existing trajectory. This step-by-step transformation can economically carry out the massive material movements resulting from the complete removal of the old ballast roadbed, the supply of the material that forms the support layer, and ultimately the concrete support layer. it can.

  Further advantages and configurations of the invention are derived from the other claims and the drawings.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The machine arrangement 1 that can be seen in FIGS. 1 to 3 mainly consists of a work vehicle 3 with several work units 2 positioned in the center, a ballast car 5 arranged in the front with respect to the work direction 4 and a rear. It consists of a gravel wheel 6. The gravel wheel 6 is followed by a silo wheel 8 with a binder 7.

  The work unit 2 arranged corresponding to the work vehicle 3 is mainly (see also FIG. 4), mainly a mixer device 9, a leveling / compacting device 10, an endless clearing chain 11 and several The track lifting device 12. The track lifting device 12 can be adjusted in the height direction and the transverse direction by means of a drive device 17 and is provided for lifting the track 13 from the ballast roadbed 16 with the ballast 15 in the formation of the work section 14. .

  The discharge opening 18 of the clearing chain 11 exists above the receiving end 40 of the transport device 19. The conveying device 19 includes a machine section 20 arranged corresponding to the work vehicle 3, and a bottom conveying belt 21 and a relay conveying belt for each ballast vehicle 5 arranged corresponding to the front end 31 of the working vehicle 3. 22.

  In the region of the supply hopper 23, there are a work cabin 24 and a throwing lower end portion 25 of the dropping transport belt 26. The receiving end of the drop conveyor belt 26 is positioned below the mixer device 9. The mixer device 9 has a charging opening 27 and is equipped with a rotatable mixer 28.

  Above the charging opening 27, there are a metering device 29 and a throwing bottom end 30 of the conveying device 32. The conveyance device 32 includes a machine section 33 arranged corresponding to the work vehicle 3, and a bottom conveyance belt 21 and a relay conveyance belt 22 arranged corresponding to the gravel vehicle 6 connected to the rear end 34 of the work vehicle 3. Composed. The metering device 29 communicates with the silo wheel 8 via a tube line 39.

  In the following, the method that can be achieved by the machine arrangement 1 will be described in detail.

  To start work, the track 13 is gripped by the track lifting device 12 and lifted from the ballast roadbed 16 to form the work section 14. The opened clearing chain 11 is guided to surround the rail 13 and closed. Under the load of the travel drive 35, the machine arrangement 1 is moved in the working direction 4 for continuous work advancement.

  The ballast 15 accommodated by the clearing chain 11 is dropped onto the accommodating end 40 of the conveying device 19 and conveyed from the accommodating end 40 to the ballast wheel 5 that can be used in an arbitrary number disposed in front. Store in the ballast car 5. By removing the ballast, the roadbed 36 is formed. In parallel with this, the gravel 37 is fed from the gravel wheel 6 to the mixer device 9 via the conveying device 32 and mixed with the binder 7 released from the metering device 29 by the mixer device 9. This mixture is dropped onto the roadbed 36 via the dropping conveyor belt 26 and the supply hopper 23, and is uniformly compacted by the compacting device 10 under the formation of the support layer 38. Thereafter, the track 13 is laid on a support layer 38 that is hydraulically bonded. In a separate and independent work process, a concrete support layer is deposited on a hydraulically bonded support layer 38, which transforms a track equipped with a conventional ballast roadbed into a rigid roadway. Can be terminated.

FIG. 6 is a side view of a front section of a machine arrangement. FIG. 6 is a side view of the central section of the machine arrangement. FIG. 6 is a side view of a rear section of the machine arrangement. FIG. 3 is an enlarged side view of the machine shown in FIG. 2.
