Definitions

  • ABSTRACT The sub-grade of a railroad ballast bed is stablized by depositing sand on the bed, removing the sand and ballast in admixture with an excavating bucket conveyor until the sub-grade has been exposed, the sand and ballast are separated from each other on a screen which receives the admixture, and two endless conveyors mounted below the screen convay the separated sand and ballast to the exposed sub-grade to deposit the separated sand thereat at a point ahead of a succeeding point where the separated ballast is deposited, thus depositing the ballast on a layer of sand in terposed between the sub-grade and the ballast.
  • a substantial factor in the quality and durability of a railroad ballast bed is the nature of the sub-grade.
  • Subgrade soil which is water-impermeable causes water stagnation after precipitation and subsequent softening of the soil.
  • the lowest pieces of ballast accordingly penetrate into the softened sub-grade soil, thus slowly lowering the level of the bed and causing misalignments in the track grade.
  • British Pat. No. 1,174,930 published Dec. 17, 1969, proposes to remove a part of the sub-grade soil during a ballast cleaning operation, in which the ballast is excavated forcleaning, to mix the soil with suitable additives and binders, and then to deposit the reinforced soil again before the cleaned ballast is laid down.
  • This avoids the need for large amounts of sand and makes the transport problem easier to solve so as to make continuous operations possible.
  • the method is not economical because of the high price of the required additives to strengthen and consolidate the soil.
  • the chemical and mechanical strength of the treated sub-grade soil is not assured for a long period of time.
  • the present invention also provides an apparatus for stabilizing the sub-grade of a railroad ballast bed supporting ties fastened to track rails.
  • the apparatus comprises means for removing a mixture of sand and ballast from the bed to leave an exposed section of the subgrade, and screening means associated with the removing means.
  • the screening means receives the removed mixture and separates the sand from the ballast, and at least two endless conveyors are mounted below the screening means to receive the separated sand and ballast, to convey the separated sand and ballast to the exposed sub-grade section and to deposit the separated sand thereat at a point ahead of the succeeding point where the separated ballast is deposited.
  • Means are also provided for sweeping sand off the ties and for planing the sand on the exposed sub-grade, which means are arranged between these points.
  • FIG. 1 is a schematic side elevational view of a mobile apparatus according to the invention and FIGS. 2 to 4 are enlarged views of structural details of the apparatus at the points of sand and ballast deposit in side elevational, top and front views, respectively.
  • the illustrated apparatus comprises frame I mounted on undercarriages 2, 2 for mobility on rails 3 of the track which are fastened to ties 4 resting on ballast bed 5.
  • the ballast is supported on sub-grade soil 6.
  • sand 7 is first deposited on the ballast bed 5, whereupon the sand and ballast are removed or excavated in admixture by a conventional excavating chain or bucket conveyor 8 until the sub-grade has been exposed.
  • ballast removing or excavating means are well known in the art of cleaning ballast, as is screening means 10associated with the removing means. Screen 10- receives the mixture of sand and ballast, and separates the sand! from the ballast.
  • the separated sand is then deposited in a layer on the exposed sub-grade and the separated ballast is deposited on the layer of sand so that the layer of sand comes to be interposed between subgrade 6 and ballast 5.
  • the means for removing or excavating the mixture of ballast and sand from the bed beneath the track to leave an exposed section of the sub-grade is designated as 8 and, as is common in the ballast cleaning art, the illustrated excavating means is a conventional endless bucket conveyor supported on frame 1 by hydraulic jack 9 to enable the conveyor to be vertically adjusted.
  • screening apparatus 10 is associated with the removing means 8, being mounted under the upper end of the removing means and rearwardly thereof, in the working direction, to receive the mixture of sand and ballast from the screening apparatus and to separate the sand from the ballast.
  • a guide or baffle means 11 arranged at the rear end of the screening apparatus serves to direct the separated sand and ballast separately to the associated portion of endless conveyor means.
  • the conveyor means comprises two endless conveyor bands each comprising a center dividing web 12a keeping the sand and the ballast separated during conveyance on adjacent portions of the conveyor bands. As shown in FIG. 4, one endless conveyor band 12 is associate with each track rail 3, the conveyor band portions facing the center of the track conveying sand 7 while the outwardly facing conveyor band portions convey ballast 5.
  • each endless conveyor band 12 may be useful to provide means for pivoting each endless conveyor band 12 in a substantially horizontal plane, as shown in broken lines in FIG. 3, so as to facilitate the even distribution of ballast and sand over the entire width of the bed.
  • Guiding device 13 is associated with the output end of each conveyor band 12 and is arranged to direct ballast vertically downwardly, the illustrated guiding device, as best shown in FIG. 3, consisting of a segmental hood hinged to the output end of the conveyor to force the ballast vertically downwardly in the direction of the downwardly pointing arrows.
  • the sand on the other hand, is thrown free off the output end of the conveyor in a parabolic path, as indicated by the paraboliform arrows in FIG. 2.
  • the separated sand is deposited on the exposed sub-grade section at a point ahead ofthe succeeding point where the separated ballast is deposited, thus causing a layer of sand to be formed on the sub-grade and the ballast to be laid on topof the layer of sand.
  • the path of the ballast may be adjusted by suitably pivoting hood 13, for instance, and the parabolic path of the sand may be changed by changing the speed of the conveyor band, if desired, thus adjusting the paths of the sand and ballast, depending on the nature of these materials.
  • Planing means 14 is arranged between the points of deposit of the sand and the ballast so that the deposited sand may be suitably planed down and compacted into a substantially even layer.
  • Yielding jack 15 adjustably mounts the planing means on bucket conveyor 8 so as to enable the position of the planing means to be adjusted in conformity to the surface configuration of the sub-grade.
  • a vibratory motor may be associ ated with the planing means to assure increased compaction of the sand layer.
  • the width of the planing means 14 exceeds the length of ties 4 so that the planing means extends beyond the tie ends and provides an even and smooth support for the entire width of the ballast bed.
  • the planing means may be so shaped as to provide a different sand layer'profile, such as a layer which is thicker underneath the rails and thinner therebetween.
  • Sweeping means is also arranged between the points of deposit of the sand and the ballast to sweep sand off the ties, the illustrated sweeping means comprising a sweeping device 16 associated with each track rail.
  • Each sweeping device comprises longitudinal carrier 18 extending along and above each rail 3 to cover the same and four successive plow-like wiping plates 17 mounted on the carrier and extending transversely thereof, each in the shape of an arrow head and extending in oblique planes.
  • the lower edges of the wiping plates are closely adjacent the upper faces of ties 4 so that, as the apparatus moves forwardly, the plates will sweep off any sand deposited on the ties and throw it unto the bed.
  • the wiping plates serve to direct the sand in its parabolic path downwardly.
  • the carrier 18 protects the rails from falling sand and ballast, and also protects the area of the ties where the railfasteners are from being covered by sand, this area not being reached by the wiping plates.
  • the above-described apparatus operates in the following manner:
  • a desired amount of sand is deposited on an existing ballast bed which, if desired, was previously cleaned. Normally, about 1 ton of sand per meter of track will suffice.
  • This first step in the operation causes practically no interruption in train traffic since a number of sand-carrying trains may be used to lay down the sand as they move over the track, and trains may freely move over all track sections on which sand has been deposited (as shown at the left side of FIG. I).
  • the mobile apparatus of the present invention is moved into position so that the excavating means 8 may remove the sand 7 and ballast 5 in admixture until the sub-grade has been exposed.
  • the removed sand and ballast are conveyed by bucket conveyor 8 to screening apparatus 10 where the sand and the ballast are separated from each other.
  • the baffle device 11 guides the separated sand to the two inwardly facing portions of the two endless conveyor bands l2, 12 while guiding the separated ballast to the two outwardly facing conveyor band portions.
  • the sand is thrown off the conveyors in an initially substantially horizontal path which then becomes parabolic and intersects wiping plates 16, the latter forcing the sand vertically downwardly onto the exposed sub-grade.
  • the arrangement of the two adjacently running conveyor bands 12, 12 makes it possible to reduce the length of the track section remaining unsupported by ballast to a minimum, thus assuring a machine length between the two undercarriages which is not excessive. This is an important consideration in dimensioning the support structures of the apparatus.
  • the apparatus frame may carry further ballast working tools, as may be desired in ballasting operations.
  • a particularly simple structure is obtained in the illustrated embodiment by arranging the conveying means as endless conveyor bands l2, 12 for pivoting in a horizontal plane, mounting a center dividing web on each conveyor band to keep the sand and ballast separated during conveyance, and to use a guiding device for the ballast at the output end of the conveyors. It would also be possible to provide a single endless conveyor provided with two dividing webs dividing the conveyor into a center portion and two side portions, the center portion conveying the separated sand and the two side portions conveying the separated ballast. Such a single conveyor would extend substantially over the entire width of the track bed and would be driven by a single power source. However, two separate conveyors, each associated with a respective rail, are lighter in weight than a single massive conveyor.
  • the thickness of the deposited sand layer may be kept as constant as possible by mounting the planing means 14 vertically adjustably. Thus, if the sub-grade surface is uneven, it will force the planing means up and down in conformity with the sub-grade surface configuration so that the thickness of the sand layer will remain unchanged.
  • ballast will be deposited on the sand layer in a rather even layer, even without special smoothing operations, particularly since the wiping plates 17, which sweep sand and ballast off ties 4, also have the effect of smoothing the surface ofthe ballast layer.
  • additional plow means may be mounted on the apparatus or follow the same to provide any desired ballast bed profile.
  • the bed provides a sufficiently firm track sup port to enable conventional mobile track correction apparatus to travel over the track for leveling and/or lining the same.
  • a method of stabilizing the sub-grade ofa railroad ballast bed comprising the sequential steps of l. depositing sand on the ballast bed,
  • An apparatus for stabilizing the sub-grade of a railroad ballast bed supporting ties fastened to track rails comprising 1. means for removing a mixture of sand and ballast from the bed to leave an exposed section of the sub-grade,
  • screening means associated with the removing means, the screening means receiving the mixture and separating the sand from the ballast,
  • the conveyor bands each comprising a center dividing web separating the sand and the ballast on adjacent portions of the conveyor band to convey the separated sand and ballast to the exposed sub-grade section and to deposit the separated sand thereat a point ahead of a succeeding point where the separated ballast is de posited,
  • ballast guiding device associated with each conveyor band at the succeeding point.
  • the means for sweeping sand off the ties comprises a longitudinal carrier means extending along and above each of the track rails, and a plurality of successive plow-like wiping plates mounted on the carrier means and extending transversely thereof.
