Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is a method for repairing a ballast roadbed in an orbit, which is a new method for repairing a ballast roadbed in parallel with this by excavating and carrying away dirty bulk material with a drilling chain. The bulk material is discharged into an orbital and ballast track repair device.
[0002]
[Prior art]
From U.S. Pat. No. 4,465,414, a method is known in which waste that accumulates during ballast cleaning is stored in a container and transported onto a waste loaded vehicle using a gantry crane.
[0003]
[Problems to be solved by the invention]
It is an object of the present invention to provide a special type of method that can perform an efficient ballast track restoration.
[0004]
[Means / Actions / Effects to Solve Problems]
According to the invention, this object is achieved with the features described in the characterizing part of the main claim using a method of the kind described at the outset.
[0005]
This method requires relatively low construction costs, allows material to be exchanged very efficiently, and when the gantry crane equipped to transport the container is first operated, a new bulk material, i.e. Ballast or gravel is brought into the renewal interval, after which the gantry crane can carry away bulk material to be disposed of on the return path. Furthermore, many existing loading wagons can be used in an advantageous manner with minimal adaptation.
[0006]
The invention also relates to a device for repairing a ballast bed according to the features of claim 3. This type of solution can reduce construction costs to a minimum, so that it does not require the use of specially designed storage wagons, although considerable bulk material storage capacity is required . The filling opening can significantly reduce the overall cost for the conveyor belt.
[0007]
Other advantages and features of the invention will become apparent from the dependent claims and the drawings.
[0008]
The invention is described in more detail below with respect to the illustrated embodiments.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The apparatus 1 shown in FIGS. 1 and 2 for repairing the ballast road bed 2 of the track 3 consists of an excavator 5 having a excavation chain 4 and any number of loading wagons 6 equipped with a loading platform 7. The entire mechanical unit can be moved on the track 3 by an on-track carriage 8 and is equipped with a power drive 9.
[0010]
The excavating vehicle 5 includes a machine frame 10 that can move at both ends on the track truck 8 and a track lifting device 11. The update interval 13 without ballast is located directly behind the drilling chain 4 with respect to the direction of movement of the device 1 (arrow 12), and the drilling chain is guided around the track 3 as an endless chain. The excavation chain 4 is rotatable and can be adjusted in the vertical and transverse directions by means of drive devices 40, 41. At the front end of the apparatus, a driver's cab or operation console 14 including a control device 15 is located.
[0011]
A filling station 16 is provided at the rear end of the excavator 5 for a filling container 17. The filling station 16 extends in the longitudinal direction of the apparatus and is arranged between the crane rails 18 and comprises a lower conveyor belt 19 with a drive device 42 and a conveyor device 20. The conveyor device 20 has a receiving end 22 disposed below the discharge end 21 of the excavation chain 4 and a discharge end 23 disposed on the filling station 16.
[0012]
A gantry crane 24 having a power drive unit 25 is provided for transporting the container 17 and is movable on the crane rail 18 by a roller 26 with a flange. In order to discharge the contents from the container 17, the gantry crane 24 is provided with a tilting mechanism 27 that can rotate horizontally around a shaft 28 that extends perpendicular to the longitudinal direction of the device.
[0013]
The distance a extending vertically between the rail plane 29 formed by the crane rail 18 (see FIG. 4) and the upper end 30 of the excavation chain 4 is designed to be shorter than the inlet frame height b. . The entrance frame height b is bounded by a rail plane 29 and a transverse beam 32 connecting the two entrance supports 31 to each other. The height c of the cab is also shorter than the entrance frame height b.
[0014]
As can be seen in particular in FIG. 3, the machine frame 10 comprises a filling opening 33 through which the ballast 34 passes, a filling hopper 35, a frame opening 36, and a conveyor belt 37 located below the machine frame 10. It consists of. The conveyor belt 37 has a receiving end 38 disposed below the frame opening 36 and a discharge end 39 located between the excavation chain 4 and the track raising device 11.
[0015]
The mode of operation of the machine unit comprising the device 1 and the loading wagon 6 will be described in further detail below.
[0016]
The dirty bulk material or ballast 34 dug by the excavation chain 4 is filled into the container 17 disposed on the lower conveyor belt 19 by the conveyor device 20, and the container 17 filled with the new ballast 34 is filled with the gantry crane. 24 to the filling opening 33 and discharged onto the conveyor belt 37. The ballast 34 is finally sent from the conveyor belt 37 to the update interval 13. The gantry crane 24 is then driven to the filling station 16 and the emptied container 17 is placed on the lower conveyor belt 19 (see broken line). Thereafter, the container 17 filled with the dirty ballast 34 is lifted by the gantry crane 24 and placed in the free space of the loading wagon 6. When the driving device 42 is operated, the empty container 17 is moved below the receiving end 23 by the lower conveyor belt 19. In the subsequent sequence, a new operation cycle is started again, and the container 17 filled with the new ballast 34 is transported to the filling opening 33, and in parallel with this, an empty container is filled.
[0017]
In an alternative embodiment, for example, gravel can be conveyed instead of new ballast to form a geological protective layer. Similarly, the loading wagon 6 can be coupled in a convenient manner to the right end of the apparatus 1 without any special mechanical equipment improvement work. Moreover, gravel may be conveyed to the filling opening 33 from the left side, and a new ballast may be supplied to the update interval 13 from the right side in parallel.
[0018]
In the case of the device 1 shown in FIG. 5, a second or forward filling hopper 43 with a second conveyor belt 37 is provided to empty the gravel stored in the container 17. The container 17 is placed on a loading wagon 6 coupled to the front end of the apparatus. The second gantry crane 24 is provided for transporting the container 17 filled with gravel. A loading wagon 6 coupled to the rear end of the device is provided for transporting a container 17 filled with new ballast. These containers 17 discharge new bulk material within the renewal interval 13 via the rear filling hopper 35 in parallel with the gravel being discharged. When this apparatus 1 is used, the formation protection layer 44 can be formed in parallel with the renewal of the ballast roadbed, and the formation protection layer 44 is leveled and solidified by the leveling / solidification device 45.
