BALLAST CLEANING MACHINE WITH COMPACTING DEVICE
ABSTRACT OF THE DISCLOSURE
A mobile ballast cleaning machine comprises a machine frame supporting a ballast excavating and conveying chain, a screening installation and a cleaned ballast redistributing apparatus arranged to receive the cleaned ballast from the screening installation and to redistribute the cleaned ballast at a ballast discharge site behind the ballast excavating site. A cleaned ballast compacting device is arranged at the ballast discharge site, the compacting device comprising a plate-shaped compacting beam extending below the track and transversely thereto at the ballast discharge site, the compacting beam having opposite ends projecting beyond the track, a carrier post supporting each compacting beam end on the machine frame, and a drive connected to each carrier post for continuously reciprocating the compacting beam in a plane extending substantially parallel to the track whereby the cleaned ballast is compacted at the discharge site in a direction opposite to the operating direction.

Description

The present invention relates to a mobile ba.llast cleaning machine mounted for mobility in an operating direction on a track consisting o~ rails fastened to ties to excavate ballast supporting the track, to clean the excavated ballast and to redistribute the cleaned ballast under the track. The machine comprises a machine frame supporting a ballast excavating and conveyinc~ chain havlng a section passing transversely under the track for excavating the ballast at an excavating site, a screening installation arranged to receive the excavated ballast from the ballast excavating and conveying chain and to separate waste from the excavated ballast to produce cleaned ballast, a cleaned ballast redistributing apparatus arranged to receive the cleaned ballast from the screening installation and to redistribute the cleaned ballast at a ballast d;.schaege site behind the ballast excavating site, and a cleaned ballast compacting device.

Such a mobile ballast clean:ing machine has been disclosed in U. S. patent No. ~,355,687, dated October 26, 1982. In this machine, the cleaned ballast leveli.ng and compacting device is mounted behind the cleaned ballast discharge si.te and comprises a leveling device i.ncluding a pair of endless ballast leveling chains for distributing t.he redistributed cleaned ballast over the ballast bed and Eor leveling the distributed cleaned ballast, a vertical pivot supporting each endless ballast leveling chain for pivoti.ng inwardly from a respective ballast bed shoulder i.n a plane ~.J,~ ? ~

underneath ~he track, a rotary drive for driving each ballast leveling chain, and a power drive linking each ballast leveling chain to the machine frame for vertically adjusting the ballast leveling chain. The power drive is connected to a parallelogram yuide mechanism mounting each ballast leveling chain on the machine frame for hori~ontal and vertical adjustment. A ballast compacting device is arranged rearwardly of the ballast leveling chains in the operating direction and is comprised of a vibratory beam extending transversely to the track and having respective ends preferably resiliently connected to elongated carriers at the respective sides of the machine ~rame. The unevenly discharged cleaned ba]last is leveled by the leveling chains and the leveled cleaned ballast is then compacted by the vibrating beam engaging the surface of the leveled cleaned ballast. This leveling and compacting device takes up a considerable amount of space since it is comprised of separate leveling and compacting units and often requires a rather high track :Lift since the two vertically adjust,ab:Le units are positioned between the level oE the cleaned ballast bed and the track. on the other nand, the balla.st compaction is not always sufficient, since the unevenly distributed cleaned ballast causes gaps in the ballast bed. This is of particular disadvantage where these gaps occur at the points where the ties are supported on the ballast.

U. S. patent No. 4,010,691, dat,ed March 8, 1977, also discloses a mobile ballast cleaning machine of the general type hereinabove described and including a cleaned ballast leveling apparatus consisting of an arrangement of A central rod-like bar extending parallel to the track ties over the entire length thereof and two outer rod-like bars. ~he ends of the central bar are pivotally joined to respective inner ends of the outer bars, and elongated guide elements freely movably connect the outer ends of the outer bars and the joined ends of the central and outer bars to a guide frame.
This leveling apparatus is pulled along by the advancing machine and will tend to level the cleaned ballast but the relatively uneven distribution of the cleaned ballast makes gaps in the leveled ballast bed unavoidable.

German patent No. 1,157,637, published November 21, 1963, discloses a ballast cleaning machine which comprises ballast compacting rams underneath the track ties for compacting the redistributed cleaned ballast. The ballast compacting rams are moved against the redistrlbuted cleaned ballast in a direction opposite ~o the operating direction of the machine, a force reacting to the ram movement against the cleaned ballast causiny forward movement of the machine ;n the operating direction.

It ls the primary object of this invention to irnprove the cleaned ballast bed and to distribute the cleaned ballast in such a manner that the track will be optimally support:ed thereon.

The above and other objects and advantayes are accomplished by the invention with a cleaned ballast compacting device arranged at the ballast discharge site and comprising a plate-shaped compacting beam extending below the track and transversely thereto at the ballast discharge site, the compacting beam having opposite ends projecting beyond the track. A carrier post supports each compacting beam end Oll the machine frame, and a drive is connected to each carrier post for continuously reciprocating the compacting beam in a plane extending substantially parallel to the track whereby the cleaned ballast is compacted at the discharge site in a direction opposite to the operating direction.

Such a compacting device enables the redistributed cleaned ballast discharyed on the excavated track bed through the spaces between the ties to be immediately repositioned and continuously compressed under the t,ies, too, the resistance of the ballast causiny compaction thereof.
Therefore, the track is supported immediately aEter the cleaned ballast redistribution at a desired and controllable level on a pre-compacted ballast bed so that the pressure oE
the succeeding undercarriage of the mobile ballast cleaning machine will further compact the ballast to provide a unlform track support. The use of a plate-shaped compacting beam enables the compacting motion to be eE~ected directly ;n t,he ballast bed Llnder the track, which has the advantage that the track does not have ~o be lifted above the desired level in the range of the compacting device and the underside oE the ~t~

ties may, therefore, be used to oppose the compacting movements.

The above and other objects, advantages and features of the invention wlll become more apparent from the following detailed description of certain now preferred embodiments thereof, taken in conjunction with the partially schematic drawing wherein FIG. 1 is a simplified and diagrammatic side elevational view of a mobile ballast cleaning machine according to the present invention;

FIG. 2 is a fragmentary and enlarged side elevation showing the cleaned ballast compactiny device of the machi.ne;

FIG. 3 is a top view of the compacting device of FIG. 2;
and FIG~ ~ is a fragmentary view similar to FIG. 1 and showing another embocliment of the machine.

Referring now to the drawing and firs~ t,o FIGS. 1 to 3, there is shown mobile ballast cleani.ng machine 1 comprisi.ng a machine frame. In the illustrated embodiment, this machine frame is constituted by a train of three connected work vehicles 2, 3 and 4. rrhe ballast cleaning rnachine is mou~tecl on undercarriages 5 for rnobility in an operating direction indicated by arrow 12 on track 8 consisting of rails 7 fastened to ties 6 to excavate ballast supporting track 8, to clean the excavated ballast and to redistribute the cleaned ballast under the track.

Ballast excavating and conveying chain 9 is supported on machine frame 10 of center work vehicle 3 and has a section passing transversely under track 8 for excavating the ballast at excavating site 14. The ballast excavating and conveying chain is an endless chain driven in a substantially triangular path for excavating and conveying the ballast, as is conventional. Track lifting device 11 is vertically adjustably mounted on machine frame 10 for raising the track at the excavating site. Furthermore, machine frame 10 carries operator's cab 13 above and lmmediately behind the excavating site, in the operating direction. Central control ~9 enables an operator in the cab to control the operation.

Screeniny installation 17 is supported on machine frame 19 of work vehicle 2 preceding work vehicle 3 and ts arranged to receive excavated ballast from ballast excavating and conveying chain 9 and to separate waste from the excavated ballast to produce clean ballast. The illustrated ballast cleaning installation comprises two screening units 18 equipped with independently operable vibrating means and arranged sequentially in, and symmetrically with respect to a vertical plane extending transversely to, the operating direction, and the obliquely extending screens ascending from a centrally located common outlet to two separate inlets for the excavated ballast. The excavated ballast is conveyed from the discharge end of the ballast excavating and conveying chain to the inlets of the two screening units by conveyor band 20, diagrammatically indicated by a series of arrows and two feeding conveyor bands 21, also diagrammatically indicated by a series of arrows. The waste coming from the screening installation is removed by conveyor band 22 diagrammatically indicated by a series of chain-dotted arrows.

Cleaned ballast redistributing apparatus 23 is arranged to receive the cleaned ballast from screening installati.on 17 and to redistribute the cleaned ballast at a ballast discharge site behind ballast excavating site 1~. This apparatus compri.ses a series of successive conveyor bands, a first one of which is disposed below the outlet of the screening installation for receiving the cleaned ballast therefrom and to convey Lt to intermediate ballast storage container 3~ whence it is rnoved to first cleaned ballast output 25 at the d;.scharge site and second cleaned ballast output 26 on rear work vehicle ~. First cleaned ballast outlet 25 produces f.irst layer 28 o cleaned ballast on the excavated track bed below track 8 and second cleaned ballast output 26 i.s constituted by adjustable discharge openings in storage container 27 for forming second layer 29 filling the cribs.

~ ~35~

As best shown in FIG. 3, first cleaned ballast output 25 is constituted by a schematically illustrated ballast distributing chute 50 with two discharge openings extending transversely to the track for forming two ballast support strips 51 for track ties 6. For dividing the cleaned ballast into a first portion discharged at output 25 and a residual portion conveyed to second output 26, a ballast flow deflector 52 is mounted pivotally about an a~is extending transversely to the track. The screening installation and the cleaned ballast redistributing apparatus are more fully described and claimed in Canadian patent application No. 529,892 filed simultaneously herewith and entitled "Ballast Cleaning Machine".

Machine frame 31 of rear work vehicle 4 supports operating unit 30 holding track tamping heads and a track lifting and lining device, the ope.rating unit being displaceable on the machine frame in the operating direction. Cleaned ballast redistributing apparatus 23 further includes extension conveyor band 32 extending rearwardly from ballast storage container 27 heyond a rear end of work vehicle ~. A pivotal ballast flow def:Lector is mounted at an inlet end of conveyor band 32 to direct all or a selected amount of cleaned ballast to ballast storage container 27 or to move excess cleaned ballast rearwardly.
~11 of the conveyor bands are preferably trough-shaped to prevent ballast or waste from spilling over the sides of the conveyor bands. All of these arrangements are described in more detail and claimed in Canadian patent applicatication No. 529,891 filed simultaneously and entitled "Mobile Ballast Cleaning Apparatus".

As best shown in FIGS. 2 and 3, a cleaned ballast compacting device 16 is arranged at the ballast discharge site and, according to the present invention, this compacting device comprises plate-shaped compacting beam 37 extending below track 8 and transversely thereto at the ballast discharge site, i.e. in the range of first cleaned ballast output 25. The compacting beam has opposite ends projecting beyond the track and a vertical carrier post 33 supports each compacting beam end on machine frame 10 laterally of the track. Drive 38 is connected to each carrier post 33 for continuously reciprocating compacting beam 37 in a plane extending substantially parallel to track 8 whereby the cleaned ballast is compacted at the discharge site in a direction opposite to the operating direction indicated by arrow 12. In the illustrated embodiment, each carrier post is a lever pivoted to the machine frame at pivot bearing 34 for pivoting about axis 35 extending transversely to the track and has an upper arm and a fork--shaped lower arm. The ends of the fork-shaped lower arms of the carrier posts are connected by plates 39 and have reinforcing plate.s 36 supporting the compacting beam ends.
Reciprocating drives 38 are cylinder-piston drives linking the upper lever arms of the carrier posts to machine frame .0 .

_9_ The illustrated ballast compacting bearn is a two-part beam, each of the compactlng beam parts having a respective one of the ends, and is comprised of two halves 40 forming a mirror image with respect to a longitudinally extending, vertical plane of symmetry o.E machine frame 10, and each compacting beam half 40 is pivoted to supporting post 33 for pivoting about vertical axis 41 into an inoperative position laterally adjacent the track, as shown in chain-dotted lines in FIG. 3, and drive 42 connects each compacting beam half 40 to supporting carrier post 33 Eor pivoting the compacting beam half. Stiffening plate 44 releasably connects the free ends of compacting beam parts 40 in the plane of symmetry, and release of the stiffening plates enables the compacting beam parts to be reciprocated independently by a respective drive 38. Vertical pivoting axis 41 for each compacting beam half 40 i9 consti.tuted by crank shaft 43 whose lower end is rotatably jou~naled in connecting plate 39 and is connected to reinEorc:ing plate 36 which holds the compacting beam half, and whose upper end is connected to drive 42.

The two-part construction oE the compacting beam has the advantage oE enabling the compacting beam to be rapidly placed in~o and out o~ operation, simply by swinging the compacting beam halves into a rest position on the track shoulders and an operative position under the track ti.es.
Connecting the two compacting beam halves with a stiffening plate increases the rigidity of the compactirlg beam during operation in a very simple manner, which improves the ballast compaction and also enables the compacting beam to withstand the continuous, cyclic impact motions. By arranginy the carrier posts as two-armed levers, a very simple, ~et efficient transmission of the driving forces to the beam will be assured to obtain high ballast compaction forcesO

The illustrated ballast compacting beam has convexly curved compacting surface 45 extending between a transverse lower edge and a transverse upper edge, surface 45 facing the cleaned ballast at the discharge site. The lower edge precedes the upper edge in the operating direction and the upper edge is close to a plane defined by the undersides of ties 6. Reinforcing plate 36 aEfixes each compacting beam end to carrier post 33 supporting this end. The convex shape oE the compacting surface provides a large area of contact between the compacting beam and the cleaned ballast thrown onto the excavated track bed so that the cleaned ballast will be rapidly moved and compacted evenly under the track ties.
Also, the curved beam will autornatically assure that any cleaned ballast falling onto the beam Erom outlet 25 moves downward to the excavated track becl. The reinfoecing plates will assure a strong connection between the support posts and the beam so that the compacting device may withstand strong forces.

A vibrating drive ~6 is connected to each compacting beam half ~0, the vibration superimposed upon the cyclic reciprocating motion of the compacting beam increasing the compacting effect, on the one hand, and causing any ballast Ealling on the beam to Elow down more rapidly.

As best shown in FIG. 2, a track depressing device 15 is linked to machine frame 10 and precedes ballast compacting device 16 in the operating direction. The track depressing device comprises a pair oE flanged wheels 47 engaging track rails 7 and vertically adjustable drive means ~8 connecting the track depressing device to the machine frame. In this manner, a controllable downward pressure force may be superimposed on the weight of the track to increase the compaction of the underlying ballast even Eurther. In addition, the track depressing device will prevent uncontrolled raising of the track under the upward pressure of the compacted ballast so that the track can be held at an accurate and uniform level.

Ballast cleaning machine 1 illustrated in FIGS. 1 to 3 operates in the followlng manner:

While the machine advances continuously in the operating direction indicated by arrow 12, the dirty and encrusted ballast is continuously excavated and conveyed upwardly by chain 9 to conveyor band 20 which conveys it to feeding conveyor bands 21, and the latter throw the excavated ballast into screening installation 17. The cleaned ballast redistributing apparatus conveys the cleaned ballast in an opposite direction to cleaned ballast output 25 at the ~ J~

discharge site behind excavating site 14. In the pivotal position oE ballast Elow deflector 52 shown in FIG. 2, a portion of the cleaned ballast is discharged throuyh ballast distributing chute 50 to the excavated track bed between the ties and another cleaned ballast portion is conveyed to second cleaned ballast output 26 where it flows through the adjustable discharge openings of storage container 27 to form second ballast layer 29 filling the cribs. If the waste component of the excavated ballast is relatively small and there is an excess of cleaned ballast, such excess cleaned ballast is removed to a following freight car, ~or example, by rear conveyor band 32 after a ballast flow deflector is suitably adjusted to direct the ballast flow to the rear conveyor band Immediately after the second cleaned ballast layer is formed, the track position is continuously corrected and the ballast is tamped under the ties to hold the corrected track in position by operating unit 30.

The cleaned ballast discharged at first outpu~ 25 is compacted by reciprocating compacting device 16 to forrn Eirst cleaned ballast layer 28. FIG. 2 illustrates the fore~nost position of the reciprocati.ng compacting device in full lines and its rearmost position, in the operating direction, is shown in chain-dotted lines. At the same time, dr;.ve means 48 will depress flanyed wheels 47 of track depressing device 15 to hold track 8 at a desired level. The operator in cab 13 can change the frequency of the reciprocating motion of compacting beam 37 in dependence on the quantity oE cleaned ballast to be compacted from control panel 49O

After completion of the ballast cleaning operation, drives 42 are operated to swlng compacting beam halves 40 into their rest posltion shown in chain-dotted lines in FI~.
3. This plvoting motion is effected by turning crank shaft 43 by 90. Afterwards, the compacting beam halves rnay be lifted above the track level by eetracting the piston rods of drive 38.

FIG. 4 illustrates ballast cleaning machine 53 comprising machine frame 54 mounted on undercarriages 55 for mobility in an operating direction indicated by an arrow on a track consisting of rails 56 fastened to ~ies 57. The machine frame supports ballast excavating and conveying chain 58 and screening installation 59 receiving the excavated ballast from the ballast excavating and conveying chain.
Cleaned ballast redistributing apparatus 60 receives the cleaned ballast from the screening installation and throws it onto the excavated teack bed at a discharge site. Such mobile ballast cleaning machines are well known.

According to this invention, cleaned ballast compacting device 61 is arranged ak the ballast discharge site and comprises convexly curved, plate~shaped compacting beam 64 and ca~rier posts 62 supporting the opposite ends of the compacting beam. The carrier posts have upper ends pivoted to the sides of machine frame 54 for pivoting about a transverse axis and drives 63 link the carrier posts to the machine frame for continuously reciprocating the compacting ~14-v~

beam in a plane extending substantially parallel to the track, as shown in full and ehain-dotted lines, whereby the cleaned ballast is eompaeted at the discharge site in a direction opposite to the operating direction.

At the beginning of a ballast cleaning operation, compacting beam 64 is pushed under the track through a prepared transverse excavation in the ballast and is attached to the free lower ends of carrier posts 61. After the completion of the operation, the compacting beam ls detached from the carrier posts so that the machine may be moved on the track to another operating site.
