Abstract

Method involves accomplishing of first and second working process alternatively, depending on the degree of contamination of the ballast bed (2). In the first working process, an upper layer (34) of the ballast is received by a front, with respect to working direction, clearance apparatus (16) and is supplied to the first conveyer belt unit (27). In parallel with this, the rest of the ballast (25) is received by a rear, with respect to the working direction, clearance apparatus (20) and is supplied to a second conveyer belt unit (29), in order to carry it away for disposal. In second working process, the ballast is received exclusively by the rear clearance apparatus and is diverted for cleaning to the first conveyor belt unit, with the front clearance apparatus being in an out-of-use position. An independent claim is also included for the installation for cleaning of a ballast bed of a track.

Description

METHOD AND APPARATUS FOR SANITATION OF A SCHOTTERBETTUNG A GLEISES.

The invention relates to a method for rehabilitating a ballast bed

a track, wherein contaminated ballast by a Räumvorrich¬

taken up by a first conveyor belt unit of Sieb¬

unit is supplied for cleaning, and a system according to the im

The preamble of claim 2 cited features.

EP 0 681 062 B1 discloses such a plant for gravel bedding

known. By a front first clearing device is the

Picking up an upper layer of gravel, around this after a

Purification due to reuse in the bedding. Of the

remaining and very heavily polluted gravel is replaced by a

subsequent second clearing device and recorded in Speicher¬

cached for disposal. Such machines wer¬

used for a rebuild, the subsoil by

Removal of a polluted gravel layer and introduction of a

Shelter layer is improved.

By US 6 637 133 it is also known, the recording power of

Clearing device to improve insofar as the bedding to be cleaned

through the joint use of a first and a second Räum¬

device and a screening plant for joint travel. is fed. This version is especially suitable for one

particularly efficient screening plant.

The object of the present invention is now in the creation ei¬

Nes method of the type mentioned, with a better An¬

adaptation to different conditions of use is possible.

This object is achieved according to the invention with a method of gat¬

Type according to the angeführ¬ in the characterizing part of claim 1

th characteristics solved.

The choice created by this method between

two different types of use advantageously allows

to various conditions prevailing at the workplace

to enter and thereby optimize the work success. Dependent

The degree of pollution can either be just the upper part of the

Ballast bedding to be cleaned while the lower part over the

Although second conveyor belt unit removed or transported away, but not

is used again. On the other hand, it is also possible only mit¬

Tels the second, larger clearing the entire Schotterbet¬

to be cleaned at once and put to a cleaning, after which

the cleaned gravel is returned to the planum.

Further advantages of the invention will become apparent from claim 2 and the

Drawing description. In the following the invention is based on a Darge¬ in the drawing

presented embodiment described in more detail. Show it:

1 and 2 is a side view of a plant for ballast bed rehabilitation

during use for carrying out the Ar¬ invention

A, and

3 and 4, the said system when used in accordance with method B.

[001 1] A plant 1 shown in FIGS. 1 and 2 (or FIGS. 3 and 4) for

Rehabilitation of a ballast bed 2 of a track 3 consists of a

Number of interconnected and based on rail vehicles

ken 4 in a working direction 5 track-traveling vehicles 6. This

essentially consist of an excavating machine 7, one of these

in the working direction 5 upstream gravel processing wagon 8, ei¬

nem Siebwagen 9 and other, not shown here in detail

Vehicles together.

The excavating machine 7 has one of two - mit¬ by a joint 10 mit¬

connected to each other - frame parts 1 1, 12 machine¬ formed

frame 13. Based on a above the joint 10 arranged

Spreizantriebs 14 are the frame parts 1 1 and 12 spread apart

bar, whereby a provided in the joint area rail chassis 4th

can be raised in the vertical direction. This leaves the Schienenfahr¬

werk 4 in contact with the track 3, which by means of Schienengrei¬

remote 15 is automatically lifted. The front in the working direction 5 frame part 1 1 is with a front

Clearing device 16 in the form of a 17 or18 by drives

and page-adjustable or rotatable, endless Räum¬

chain 19 for receiving contaminated ballast 25 connected. Die¬

a receiving end 26 of a first conveyor belt unit 27 is zuge¬

arranges, in the machine longitudinal direction to the ballast processing

gene 8 and continues to the screening carriage 9 and in the form of a dashed

dotted thick line is shown.

At the rear frame part 12 is another, rear Räum¬

Device 20, as height and side adjustable by drives 21

or by a drive 22 rotatable, endless clearing chain 23 aus¬

is forms and a receiving end 28 one in the machine longitudinal direction

extending second conveyor belt unit 29 is assigned. These ver¬

runs above the first conveyor belt unit 27 approximately parallel to

this. Another, third conveyor belt unit 30 (shown by

dashed thick lines) is provided to the gerei¬ in the sieve 9

gravel against the working direction 5 behind the excavation site

zurückzutransportieren and drop off again to track 3.

In the front end region 32 of the excavating machine 7 is a Umlenkein¬

provided direction 33, which serves the of the rear Räumvor¬

direction 20 coming ballast 25 optionally from the second För¬

derband unit 29 to the first conveyor belt unit 27 redirect. in the Case shown here, this deflection 33 consists of a

Swing drive 24, with the help of which in the working direction 5 rear

End 35 of a - a part of the second conveyor belt unit 29 forming

- Conveyor belt 36 can be folded up in the vertical direction

(see Fig. 4). As a result, the directly underlying Förder¬

Band 37 of the first conveyor belt unit 27 quasi exposed, so that the

Gravel 25 now just from the second conveyor belt unit 29 directly

can fall on the first conveyor belt unit 27.

In the following, the two variants A and B of erfindungsge¬

short description of the process.

In the first working method A (see FIGS. 1 and 2) is - in by

Rail gripper 15 or further track lifting devices 38 gehobe¬

nem track 3 - based on the front sweeper 16 only the upper

Schotterschichte 34 of the ballast bed 2 away. This contaminated

Gravel 25 is based on the first conveyor belt unit 27 in Arbeitsrich¬

5 forward to a screening unit 39 of the screen carriage 9 ab¬

transported (see small arrows). When passing through the ballast bed

preparation cart 8, the gravel 25, if desired, also by

pretreated a pre-separator 40 and / or an impact crusher 41

to increase the cleaning performance. The cleaned gravel

is by means of the third conveyor belt unit 30 from the screen 39 against the

Working direction 5 transported back to the area behind the rear Clearing device 20 ab¬ on the meantime rehabilitated Planum 31 again

to be thrown. Parallel to this, based on the second, rear

Reaming device 20, the remaining remainder of the ballast 25 of Schot¬

terbettung 2 excavated via the second conveyor belt unit 29 in

Working direction 5 forward to an end 42 of Appendix 1 transpor¬

and there - together with the from the pre-separator 40, Prall¬

crusher 41 and sieve 39 accumulated overburden - for disposal, e.g. on

not shown bulk goods transport vehicle is loaded.

In contrast, in the second working method B (see FIG. 3

and 4) the front sweeper 16 is not in use

the front clearing chain 19 in its raised Außerbetriebs¬

position. In this application of Appendix 1 as a high-performance cleaning

tion machine lifts the clearing chain 23 of the rear clearing device

20 now the entire ballast bed 2 at a time and throws the

contaminated ballast 25 on the second conveyor belt unit 29 from. in the

Front end portion 32 of the excavating machine 7, the ballast 25th

now due to the folded deflection 33 on the direct

underlying first conveyor belt unit 27 diverted and from this

the screening unit 39 is fed to the ballast cleaning to then on the

third conveyor belt unit 30 to be returned to track 3 again.

To increase the screening performance, it is advantageous if the ballast 25th

is pre-cleaned by the pre-separator 40 and the impact crusher 41. This makes it possible, with only a single sieve by the

very efficient broaching chain 23 picked gravel

to clean.

In the context of the invention are also other embodiments

for the deflection 33 possible. So could the end 35 of För¬

derbandes 36, instead of being folded up, simply side or

horizontally pivoted or moved in its longitudinal direction

be to the underlying conveyor belt 37 of the first Förder¬

band unit 27 to make accessible. Also a use of Umlenk¬

to fold would be conceivable.
