Abstract

A track tamping machine has a machine frame extending in a longitudinal direction and tamping units mounted to the machine frame. A first or upper transverse guide extends in a transverse direction perpendicularly to the longitudinal direction. Two sliding blocks are mounted for displacement in the transverse direction independently of one another on the upper transverse guide. A second or lower transverse guide is positioned vertically below the upper transverse guide and parallel thereto. The lower transverse guide is mounted in the sliding blocks for displacement relative thereto in the transverse direction. Two inner unit frames are connected to a respective one of the sliding blocks and support a tamping unit in each case. Two outer unit frames are positioned in each case farther from a vertical machine center line-with regard to the transverse direction-than an adjacent one of the inner unit frames and support a respective tamping unit. The outer unit frames are mounted on the lower transverse guide for displacement in the transverse direction independently of one another. Transverse drives are provided for independent transverse displacement of the sliding blocks, or the inner unit frames, along the upper transverse guide, and displacement drives are provided for independent transverse displacement of the outer unit frames along the lower transverse guide.

Description

 Tamping machine

The invention relates to a track tamping machine with the in the preamble

Characteristics cited in claim 1.

By GB 2267 304 such a machine is known (see Fig. 5), whose

four aggregate frame in a particularly large extent independently von¬

are transversely displaceable. This can also be due to irregular

Rail track marked points sections are supported.

To be able to move the two outer unit frames as far as possible

NEN, the upper and lower transverse guides are common to the normal

Machine longitudinal direction shifted. However, this is a relatively aufwen¬

Dige construction required.

The object of the present invention is now in the creation

a machine of the type mentioned, with the constructive

Effort for an independent Querverschiebbarkeit the four Aggre¬

gatrahmen is reducible.

This object of the invention is with a machine of the genus

Appropriate type ange¬ by ange¬ in the characterizing part of the main claim

solved features solved.

With this constructive solution, the lower transverse guide with the aid of

supported both inner unit frame and can with a Querverschie¬

exercise one of the two outer unit frame to extend it Movement path to be taken automatically. An inevitable with it

connected shortening of the displacement path for the second outer Ag¬

gregate frame is not problematic insofar as this in Weichen¬

section is to be inserted within the main track.

Further advantages of the invention will become apparent from the dependent claims and

the description of the drawing.

In the following the invention with reference to an illustrated in the drawing

Embodiment described in more detail. Show it

Fig. 1 is a side view of a tamping machine, and

Fig. 2 shows a cross section through the machine, wherein only a left half

of Stopfaggre¬ symmetrically arranged with respect to a machine center

gaten is shown.

An illustrated in Fig. 1 track tamping machine 1 has an elongated,

bridge-shaped machine frame 2, the on rail bogies 3 on

a track 4 is movable and at the end of cabs 5 and the center

a work cabin 6 are arranged. An energy unit 7 serves to Beauf¬

Suppression of a traction drive 8 and a abge on the machine frame 2 abge¬

supported, equipped with a Zusatzhebeeinrichtung Gleishebeaggrega¬

9 and this immediately downstream in the direction of work, one each

Pair of tamping tools 16 having tamping units 10. A Nivel¬

Lier and Richtbezugsystem 28 is to control the work units in Ein¬

provided for. To machine 1 also in turnout and crossroads To use effectively, the tamping units 10 - as in

Figure 2 is described in more detail - ver¬ in the cross machine direction

slidably mounted.

[0011] According to the symmetric arrangement already mentioned, two are each

Zug on a machine center 11 closer internal unit frame 12th

and two outer unit frame 13 (of which only the left Ag¬

gregatrahmen 12, 13 is shown) is provided. At each of the total

four unit frame 12, 13 is a by drives 14 on vertical Führun¬

gene 15 independently height adjustable, stuffing tools 16 exhibiting

Stopfaggregat 10 stored.

Each unit frame 12,13 is a guide bush 17 for storage

on lower transverse guides 18 (of which only the front one is visible)

and for displacement in a - verlau¬ normal to the machine direction

fenden - assigned transverse direction 19. Each inner unit frame 12 is in

Area of the guide bushing 17 connected to a sliding block 20, the on

one - with respect to a vertical - upper transverse guide 21 slidably ge¬

stores. For displacement in the transverse direction 19, each inner Aggregatrah¬

men 12 with a machine frame 2 attached to the transverse drive 22 ver¬

prevented. Each outer unit frame 13 is with the help of one on Maschinen¬

frame 2 hinged displacement drive 23 along the lower Querfüh¬

ments 18 displaceable. The upper transverse guide 21 is be¬ each end on the machine frame 2

strengthened and supported in the middle. Each lower transverse guide 18 is on the one hand by

the sliding blocks 20 (of which only the left is shown) on the obe¬

Ren transverse guide 21 and on the other hand on one with the machine frame. 2

connected storage 24 supported and relatively free in the transverse direction 19

movable. On each lower transverse guide 18 is an end stop 25th

intended. Another, connected to the machine frame 2, höhen¬

adjustable safety stop 26 serves to fix the lower Quer¬

18 during the transfer.

For a Unterstopfung a normal section of one of the machine

1 traveled track 4 are the (four in all) tamping units

10 with their respective unit frame 12,13 in the in Fig. 2 with full Li¬

position shown. To the Unterstopfung one of the track 4 or the

Machine 1 leading away turnout 27 is the this neigh¬

bare outer unit frame 13 under the action of Verschiebean¬

drove 23 along the lower transverse guides 18 moved. It will

after contacting the stop 25 through the guide bushing 17 each

lower transverse guide 18 together with the outer unit frame 13 querver¬

pushed to finally the associated Stopfaggregat 10 in the outermost,

with dash-dotted lines position shown to the clogging of äu¬

First turnout section 27 to bring. Parallel to this, the be¬

neighboring aggregate frame 12 by means of the transverse drive 22 in the direction the switch portion 27 is shifted, wherein by the co-displaced

Sliding block 20 er¬ a support of the protruding lower transverse guide 18

is enough. Also parallel to that in the transverse direction 19 gegenüber¬

lying shift and lateral drives 23, 22 depressurized, so

that the two - from the turnout section 27 further distanced - Aggregat¬

Frames 12, 13 automatically with the displacement of the lower transverse guide

18 be moved.
