Description

The invention. concerns a railway construction machine for the

  relining or distributing and profiling a railway ballast with a rolling vehicle chassis supported on railway rolling stock and connected via a hinge to at least one displaceable sidewall plow in height and laterally

  -by way of training commands.

  According to the publication No. 2,424,360 of French Patent No. 79.10 074, a rolling machine for the construction of a railway track is known for the relining and profiling of the ballast of a railway track, which comprises a median plow mounted in a displaceable or adjustable manner in height on the machine frame. On both longitudinal sides of the machine or in the lateral region of the median plow is mounted, respectively, a flange plow movable in height and laterally by means of hydraulic controls. These elongated flank plows, forming an angle up to about 45 with the longitudinal direction of the machine in use of work, have the task of conveying, from below upwards in the direction of the railway, the excess ballast on the flanks so that, on the one hand, sufficient ballast exists in the central region of - the railway and, secondly, simultaneously the flank of the ballast bed is profiled with a corresponding accuracy. In this operation, unfortunately, it is not always possible to avoid that at the free end 30 of the sidewall plow, in particular at the beginning of the work of the machine in continuous advancing motion, or in case of accumulation of ballast, individual ballast grains fall into the marginal or edge zone of the flank against the direction of transport. So can not be obtained any

  precise termination at the lower end of the ballast bed flank, so that these often considerable quantities of excess ballast must again be removed most frequently by hand. This is not economical and is also often linked to dangers since, during each implementation of personnel, the corresponding control bodies, for the observation of the traffic or the circulation of the trains, must be

present during such work.

  The task of the invention is therefore to create a railroad construction machine for the relining or distribution and profiling of the railway ballast of the kind described at the beginning, by which at the same time as the profiling of the sidewall. of ballast bed by the sidewall plow can also be obtained a precise termination of the ballast bed flank in the transition zone or passage to the landing or to the

platform of the railway.

  This problem is solved according to the invention with a railroad construction machine of the type described at the beginning by the fact that on the flank plow in its free end portion located opposite the articulation is provided a brush of sweeping device which can be rotated by means of a drive control and arranged with its plane of rotation at an angle to the longitudinal direction of the sidewall plow. By this advantageous arrangement of a sweeping brush provided in the extreme zone of the flank plow can be obtained, with only a small overcrott of construction expenses, a fast and complete transfer of the ballast stones, located in the sweeping region. of the

  brush, up to the adjacent ballast bed flank.

  Thus, in a single work roll for profiling the sidewall, a separating line extending substantially in a straight line between the ballast bed flank and the landing or the railway platform can be obtained. as a termination of the profiling operations. Such a clean separation line has, in addition to the aesthetic effect of a net shaping, the particular economic advantage that the ballast remains entirely in the flank zone and, thus also for subsequent treatments, in the d-zone. action of the flank plow and is therefore also

  always accessible to a rational mechanical shaping.

  An advantageous development of the invention is that the drive control of the sweeping brush is mounted on a support frame which is connected via a pivot point.

  having an axis extending substantially perpendicular

  the longitudinal direction of the plow, the extreme upper portion of the sidewall plow and a pivoting control. By this special arrangement on a support frame, the sweeping brush is advantageously displaceable upwards by pivoting into an out of service position by use of the swivel control. Thus, the sweeping brush, protruding from the free space profile or template obstacles during use, for example during the presence of an obstacle, is movable upwards by pivoting while the flank plow continues to be usable without being hindered for flank profiling. In addition, the sidewall plow can also be used in normal operation, if

  necessary, also without this sweeping brush.

  The support frame, connected to the sweeping brush, may, in accordance with another advantageous configuration of the invention, be mounted, together with the pivot point and the pivoting control, on a carrier plate which is hinged to the upper edge portion of the sidewall plow, so as to be pivotable about an axis extending in the longitudinal direction thereof and is connected to a pivotal control. This advantageous arrangement of the sweeping brush allows an application of the support frame, connected to the sweeping brush, against the side or the internal face of the sidewall plow turned towards the ballast. In this compact position, the sidewall plow is applicable, together with the sweeping brush for its out of service position within the obstacle gauge or clearance profile, tightly to the side surfaces of the sidewall construction machine. track. Another judicious development of the invention consists in that the sweeping brush is constituted by at least six to eight flexible flexible pipe-shaped sweeping elements arranged radially in a plane and which are removably connected to an annular appendix of the control device. With these flexible pipe-shaped scanning elements a relatively wide scan area can be obtained with low elastic deformation of the radially outer ends

  in the area of contact with ballast pebbles.

  Thus, ballast stones, located at a relatively greater distance from the end of the plow on the landing or the railway platform, are also still individually seizable and transportable.

on the flank.

  According to another development of the invention, the sweeping brush is made to extend, in its working position, with the periphery determined by the radially outermost portions of the scanning elements, approximately to the lower edge. of the flank plow or to protrude slightly protruding beyond it. This positioning of the sweeping brush, in relation to the sidewall plow, safely or reliably excludes a run-off of ballast pebbles between the plow edge and the sweeping brush. In addition, the delimitation of the ballast bed flank can be fixed

  precisely by the flank plow edge.

  Finally, yet another advantageous development of the invention consists in that the rotation or working plane of the sweeping brush, formed by the scanning elements and extending substantially vertically, extends, relative to the plane of the sidewall. ballast bed, substantially perpendicular and with a small inclination or at an acute angle transverse to the moving direction of travel and preferably forms an angle of about 300 to about 600 with the longitudinal direction of the sidewall plow

  according to the limit of pivoting travel of the plow.

  Such an angular position of the sweeping brush, with respect to the sidewall plow, results, thanks to the resulting arrangement substantially orthogonal to the longitudinal direction of the railroad, by a path

  or scan path as much as possible short.

  The invention will be better understood and other objects or purposes, features, details and advantages thereof will become more clearly apparent on reading the

  explanatory description which will follow by referring to

  attached schematic drawings, given solely by way of non-limiting example illustrating a specific embodiment currently preferred of

the invention and in which:

  FIG. 1 is a side view of a railroad construction machine constructed in accordance with the invention for relining and profiling the ballast of a railroad track, with a sweeping brush in the service position. or operating and arranged on a flank plow; FIG. 2 represents a partial front view of the sidewall plow along the arrow II of FIG. 3, with the sweeping brush in the operating or operating position and the out of service position, raised or folded upwards, the sweeping brush represented by broken lines in phantom lines; Figure 3 is a partial top view of the sidewall plow and the sweeping brush along the arrow III of Figure 1; FIG. 4 is an enlarged side view of the sweeping brush in the longidudinal direction of the plow (without the drive control 19), along the arrow IV of FIG. 2; and FIG. 5 is a perspective view of the sidewall plow during profiling of a ballast bed flank, together with the sweeping brush mounted at the end of the plow, for the production of a

precise end of the sidewall.

  A railroad construction machine 1, visible in FIG. 1 and made in the form of a ballast plow for relining or distribution and profiling of the ballast, essentially consists of a rolling vehicle chassis 3 supported on trains. 2 and on which is arranged a driving cabin 4 with a central driving or driving system 5 and a locomotion device 6. At the rear end of the rolling vehicle chassis 3, with respect to the working direction represented by an arrow 7, is mounted a sweeping brush 8 can be rotated and movable height by means of a drive control. It extends across the width

  of a railway line 11 constituted by rails 9 and.

  10. On the underside of the chassis of the rolling vehicle 3 is located, centrally between the two rail running gear 2, a median plow 12 movable height for the treatment of the ballast located in the region or in the vicinity of the sleepers. In front of this median plow 12 is placed bilaterally a side plow 13 which is respectively connected to the rolling vehicle frame 3 via a hinge 14 and drive commands 15 for lateral displacement and height. On the flank plow 13 in the free end zone thereof opposite the hinge 14 is provided a sweeping brush 16 for the transport of ballast 17 in the direction of the flank plow 13 or a Ballast bed flank 18. As can be seen in FIGS. 2, 3 and 4, the sweeping brush 16 is arranged with its plane of rotation.

  rotation at an angle θ of about 35 to 40 degrees

  to the longidudinal direction of the plow of

  flank 13 and connected to a hydraulic control device

  19. The control device 19 of the sweeping brush 16 is mounted on a support frame 20. This is mounted, via a hinge location 22 having an axis 21 and a device hydraulic pivot control 23, on a carrier plate or stepped plateau plate 24. The carrier plate 24 is articulated to the upper marginal portion of the sidewall plow 13, so as to be pivotable about an axis extending in the longitudinal direction thereof or around joints 25 and

  is connected to a pivot control device 26.

  The sweeping brush 16 consists of eight swept elements 27 flexible and shaped hose, arranged radially in a plane of rotation. In the working position of the sweeping brush 16, the scanning elements 27 extend to a lower edge of the flank plow 13 or slightly beyond this edge 28. As can be seen in the view of FIG. 3, the rotation or working plane of the sweeping brush 16, formed by the sweeping elements 27 and extending vertically, forms an angle <of about 35 to 40 with the longitudinal direction of the plow. The sweeping brush 16 occupies, according to the angular position of the sidewall plow 13, movable laterally and vertically, relative to the direction of work or the side of the ballast bed, a slightly acutangular position, this angle B being advantageously from about 5 to 100. The hinge 25, connecting the carrier plate 24 to the sidewall plow 13 and extending in the longitudinal direction thereof, is arranged in the longitudinal median zone of the carrier plate 24, thanks to what is it in use of the work of the sweeping brush 16 protrudes beyond both sides of the sidewall plow 13. The axis 21 of the hinge location 22, connecting the

  support frame 20 to the carrier plate 24, extends

  specifically to the longitudinal direction of the plow

sidewall 13.

  In the enlarged view of the sweeping brush 16 in Figure 4, it is visible that the pivot control device 26, placed in connection with the carrier plate 24, is supported on a flange or console connected to the rear or back side 29 The sidewall plow 13 has a front face 31 placed in contact with the ballast 17 of the ballast bed flank 18 and made in a slightly curved manner, the lower edge 28 being a little protruding towards the flange plow 13. before

  in the sense of work. The scanning elements 27 of the scanning brush 16, arranged radially, are removably connected for rapid replacement or exchange to an annular end or appendage 32 of the control or drive device 19. On the rear or back side 29 of the flank plow 13 are provided reinforcing ribs 33 extending perpendicularly to

  the longitudinal direction of it.

  As can be seen in the perspective view in FIG. 5, after the flange plow 13 and the sweeping brush 16 are actuated, an accurate delimiting line 34 extending in the longitudinal direction of the railway exists between the ballast bed flank 18 on the one hand and a landing or a railway platform 35 on the other hand. In the drawing, it is furthermore visible that, in the working direction in front of the sweeping brush 16, the ballast 17 is still located in the bearing area 35 adjacent to the ballast bed flank 18 and, the region o

  no job operation has been performed yet.

  In the following, the operating mode of the railway construction machine 1 is described more

in detail.

  During the empty or inoperative movement of the machine 1 to the place of use, the sidewall plow 13 is raised in the transfer position indicated by broken lines in phantom in FIG. 16 was raised upwardly by biasing the pivot control device 23 and the carrier plate 24 was pivotally urged by the pivot control device 26 to the front side 31 of the sidewall plow 13 (FIG. broken lines in phantom

  in Figure 4). After reaching the place of use

  The central plow 12 and the sweeper 8 are lowered and the two sidewall plows 13 are biased laterally and vertically by the control devices 15 for application against the ballast bed flank 18. After that, the carrier plate 24, by biasing the pivot control device 26, is raised upwardly (FIGS. 2 and 3) and the carrier 20 is brought together with the sweeping brush 16 by biasing the pivoting 23, from the off position (broken lines in phantom in Figure 2) in the service or operating position. After biasing the control device 19 of the side plows 13, the sweeping brush 16 or the scanning elements 27 thereof are rotated in the direction represented by an arrow 36 (FIG. 5). During the rolling progress of work, progressing continuously, in the direction of the arrow 7, and at the same time as the profiling of the ballast bed flank 18 by the rotating scanning elements 27, the excess ballast 17, located on the landing or the railway platform 35, is transported on the edge of the ballast bed flank 18 with the creation of a precise boundary line 34. It is however also possible, in particular during traversing working passages. repeated, leave the sweeping brush 16, during the first passages or work operations, in the off position raised by pivoting upwards and implement only the sidewall plow for the first profiling work. In this case, it is only during the last traversing working passage that the sweeping brush 16 is brought into the service or operating position and, during this last traversing working passage, the ballast 17, located on landing 35, is transferred to the bed

ballast 18.
