In order to create advantageous plowing conditions, it is proposed that the tool carriers on each side of the machine frame be rotated by means of a rotating device (25, 34) about a vertical axis of the machine frame, which are arranged between the two outer ballast deflector shields (19) spaced apart in the longitudinal direction of the machine frame, in such a way between two working positions are pivotably mounted so that a tool that is attached in each case can be connected alternately to the two outer ballast guide plates of the associated machine frame side.

Description

The invention relates to a ballast leveling machine comprising a machine frame that can be moved on rail chassis, a central plow equipped with rail transfer profiles, to which two outer ballast deflector shields, which are spaced apart in the longitudinal direction of the machine frame and project laterally beyond the rail transfer profiles, are assigned to each side of the machine frame for ballasting and leveling a track bed, and one lateral one each Tool carriers on each side of the machine frame for machining flanks of the track bed, the tool carrier being designed in such a way that a tool attached to the tool carrier can be connected to an associated outer ballast delineator, the tool carriers on both machine frame sides being pivotably mounted between two working positions by means of a rotating device about a machine frame vertical axis are that an attached tool is assigned alternately to the two outer ballast delineators eten machine frame side can be connected.

Such a gravel leveling machine is disclosed in the RU2398061C1 . The tool carriers on both sides of the machine frame are pivoted by means of a rotary device about a vertical axis of the machine frame in the area of the central plow between the two sides of the machine in the area of the longitudinal axis of the machine. Although plowing tasks can be carried out with it, other work such as excavating, mowing, changing sleepers and lifting work cannot be carried out with it due to the design.

Such gravel leveling machines are equipped with ballast and leveling devices that can be adjusted relative to the machine frame, the plows, with a gravel sweeping system, a steep conveyor belt, a gravel silo, and a Control device for all components and in particular for the central plow and the tool carrier.

Such a gravel leveling machine is, for example, by EP 0 572 370 A2 known with a machine frame supported on rail chassis. This has a height-adjustable center plow between the rail chassis and flank plows in front of it. On each longitudinal side of the machine, a height-adjustable flank plow provided with a plow blade with a pivot point and a support frame arranged on the machine frame is assigned.

Out EP 2 775 035 Gravel leveling machines are known which have a gravel sweeping device, a steep conveyor belt and a gravel silo. There are also ballast storage devices known which transfer the ballast to coupled ballast storage wagons via a floor belt and a transfer conveyor belt. In addition, ballast sweeping devices are known which are equipped with a transverse conveyor belt. Optionally, the ballast can be transported by the broom onto the cross conveyor belt and ejected to the left or right, or conveyed onto the steep conveyor belt to store the ballast in the silo. Such ballast leveling machines are used for the prescribed ballasting of a track, whereby any existing track sections with a lack of ballast can be supplied with new ballast via a ballast silo, or they take up the excess ballast and store it in the silo of the ballast leveling machine or on a coupled ballast storage wagon.

Typically, the drives of the plows and their adjustment devices are carried out by means of hydraulic cylinders. Position sensors for measuring the extension can be integrated into the hydraulic cylinders.

Tool quick-change systems that allow different tools to be gripped and held are known in particular from excavator technology ( AT391501B ).

Known flank plows ( EP 0 572 370 A2 ) cannot be rotated around the vertical axis. The disadvantage of this is that you can only transport the ballast from the flank directly into the middle plow in one working direction. If a track is newly ballasted, it has to be tamped up with several tamping passes. Between these operations, the ballast has to be leveled several times with the ballast leveling machine and shifted or rearranged according to the work requirements. This requires multiple leveling runs. If full leveling can only take place in one direction, the ballast leveler must always return to the starting point. During these grading operations, the tamping machine must clear the work area and wait for the grading machine to finish its work. Before the tamping machine starts work, the leveling machine must release the work area. Maintenance work is expensive and causes additional costs because of the associated operational disruptions. A disadvantage of leveling machines is that they have long downtimes during which they wait for other machines to finish their work. This is inefficient and costly. It would be desirable if they could carry out other work such as simple excavation work, lifting work, mowing work or the sleeper replacement of individual sleepers etc. during these dead times. Another disadvantage of conventional side plows is that although the ballast can be fed to the side plow on one side, it cannot be distributed on the opposite side by the other side plow, for example on the other side.

The object of the present invention is to provide a ballast leveling machine of the type described above, with which a full leveling work can be carried out in one operation in both directions, regardless of the direction of work, so track bed ballast both when Can be equally advantageously distributed in reverse and when driving forward.

This object is achieved according to the invention with the ballast leveling machine described at the outset in that the tool carriers on each side of the machine frame are mounted pivotably between the two working positions by means of a rotary device each about a vertical axis of the machine frame, which is arranged between the two outer ballast deflectors that are spaced apart in the longitudinal direction of the machine frame on each side of the machine frame.

The tool carriers are arranged on a rotary device with the attached tool. The rotating device is arranged centrally between the two outer ballast deflectors, which are spaced apart in the longitudinal direction of the machine frame, on each side of the machine frame. If the tool is a side plow sword, it can be rotated depending on the working direction and moved to the assigned gravel deflector plate and connected to it so that the gravel can be transported seamlessly into the middle plow in one operation. In this case, connection means that ballast can be transferred from the side plow sword to the respective ballast guide plate and thus to the middle plow. Depending on the direction of work or work process, for example ballast can be conveyed from both sides to the middle, from the middle to both sides or from one side to the other side, it is possible to connect the attached tool alternately to the two outer ballast deflector shields of the assigned machine frame side .

Advantageous developments of the invention are presented in the dependent claims.

In particular, the tool carriers with the attached tools on both sides of the machine frame can be displaced in the longitudinal direction of the machine frame in such a way that a tool on one side of the machine frame can be attached to an in connects the front tool in the direction of travel and the other tool on the other side of the machine frame to a ballast guide plate at the rear in the direction of travel and that ballast can be conveyed from one side of the track bed into the middle plow and on the other side of the track bed out of the middle plow over the entire width of the bed and that with the invention in both directions of travel.

The tool carrier is preferably arranged on a one-part, two-part or multi-part arm, in particular a telescopic arm, with the tool carrier acting on the tool-side end of the telescopic arm via an adjustment device (D) with rotary devices that allow a connected tool to be manipulated by three, in particular orthogonally to one another aligned spatial axes permitted. This allows any tool to be aligned in the desired manner depending on the working direction.

If the tool carrier is equipped with a tool quick-change device, it is possible to quickly switch between individual tools, such as a side plough, excavator shovel, mowing device or a clamping device for gripping and manipulating sleepers during operation.

For this purpose it is advisable if the outer ballast deflector shields in the area of the rail transition profiles can be pivoted about a vertical axis with an actuator. In this way, transitions between the side plow sword, whose angle of attack can vary depending on the work to be carried out, and the central plow between the rail transition profiles can be made smoother and a ballast transition can thus be improved.

The flank plow and the respective tool are attached, for example, to an articulated crane arm which has a telescopic arm and which is arranged, in particular laterally, on the machine frame between the two outer ballast deflectors spaced apart in the longitudinal direction of the machine frame.

With the invention, there is the great additional advantage of a multifunctional use of the side plow. This means that individual defective sleepers can be replaced, adjacent bushes or embankments can be mowed, drainage channels can be excavated or new ballast can be loaded into the silo, which can be used for minor work at points on the track with a lack of ballast via the silo and the outlet flaps at points where there is a lack of ballast can be drained. Since both side plows are rotatably mounted, there is the advantage that both side plows can be positioned in such a way that a continuous flow of ballast over both sides of the ballast bed is possible.

According to the invention, the tool can be rotated about a machine frame vertical axis with a rotary device so that it can be rotated about the vertical axis in any working direction such that, for example, gravel can be seamlessly routed in one operation into the central plow for distribution. This enables full-fledged plowing with a center plough, side ploughs, and side plow blades in both working directions.

1 shows schematically a gravel leveling machine SPM in the working direction AR and against the working direction AR equally can be used. The gravel leveling machine SPM is equipped with a sweeping brush 39 and a broom shaft 40, with a gravel silo 42, a side plow sword A, 5 on the left and right of a machine frame 9, with a center plow B and with a driving and working cabin 43. The machine frame 9 of the SPM gravel leveling machine rests on two rail chassis 10, bogies with which the SPM gravel leveling machine can be moved on rails 11. The rails 11 are mounted in the ballast bed 2 over sleepers 1 . The sweeping brush 39 comprises a sweeping shaft 40 that can be driven in rotation and sweeps the ballast onto a steep conveyor belt 41 if necessary. The ballast stored in the silo 42 can be metered out via ballast hoses 46, 47 to the left and right of the rail 11 on both sides of the ballast leveling machine SPM. The middle plow B has rotatable gravel deflector plates 17, 18, 19 on the inside and outside. About an actuator 8 side plow sword 5 can be adjusted in height. On the SPM ballast leveling machine, a side plow A, 5 is mounted on the left and right of the machine frame 9 between the two outer ballast deflector shields 19 spaced apart in the longitudinal direction of the machine frame and can be pivoted about a machine frame vertical axis by means of a rotary device (25, 34). The middle plow (B) equipped with rail transfer profiles 15 is assigned two outer ballast deflector shields 19 for ballasting and leveling a track bed, which are spaced apart in the longitudinal direction of the machine frame and project laterally beyond the rail transfer profiles 15. The ballast leveling machine also has a loading area on which two ballast sweeping shafts 45 are mounted and an auxiliary crane 44.

2 Figure 12 shows a machine cross-section of a side plow A according to the prior art. The side plows A are constructed as follows. A height adjustment device 8 which is connected to a rotary joint D is located on a telescopic arm 6 which is mounted on the frame 9 so that it can rotate about a machine longitudinal axis. The swivel joint D holds the side plow blade 5 and can bring it into the desired position relative to the gravel flank 2 . The machine moves over carriages 10 on rails 11 on sleepers 1 in

Ballast bed 2 resting on the planum 3. Across the track is positioned via the telescopic arm 6, 7, 12, the height position is accomplished by pivoting 13 of the telescopic arm and by adjusting the height 8, 14. Smaller movable flaps 20 are located at the front and rear ends of the main plow sword 5.

3 shows schematically the flow of ballast 21 in a side plow A of this type, known from the prior art, in the working direction AR. The center plow B has 4 fixed gravel deflectors 16 on the inside. The flow direction of the ballast 21 can be selected accordingly via two movable ballast deflectors 17, 18. In the figure, they are positioned in such a way that the ballast is pulled up laterally from the flank with the flank plow 5 and guided via the movable outer ballast deflector shields 19 into the inner area, between the rail transfer profiles 15 of the middle plow from the left to the right ballast head. The basic positions of these ballast deflectors are: guidance of the ballast from right to left, from left and right to the middle of the track and from the middle of the track to the left and right to the outside. On the outside, the middle plow B has movable ballast deflectors 19, which can be pivoted about a vertical axis with an adjusting drive. The side plow A must be adjusted in such a way that the side plow sword 5 connects almost seamlessly to the flexibly adjustable gravel deflector plate 19 with its impact side. Otherwise the ballast 21 would be partially discharged via a remaining gap. Rail transfer profiles 15 guide the ballast over the rails 11.

4 shows a schematic top view of two tools arranged according to the invention, here for example side plow blades 5 which can be used in both working directions AR and BR. A side plow A, 5 is installed on the left and right of the machine frame, centered between the two outer ballast deflectors 19 spaced apart in the longitudinal direction of the machine frame. The tool carriers are on each side of the machine frame with the attached Tool, for example the side plow blade 5, by means of a rotary device 25, 34 about a machine frame vertical axis, which is arranged between the two outer ballast deflectors 19 spaced apart in the longitudinal direction of the machine frame on each side of the machine frame, is pivotably mounted between two working positions in such a way that the tool attached in each case can be attached alternately to the two outer Schotterleitschilde 19 of the associated machine frame side can be connected. The rotary devices 25, 34 are each assigned to one side of the machine frame and are arranged on the machine frame in the area of this. The position of the left-hand tool C in the working direction BR is shown in dashed lines. The tool C can be manipulated with a telescopic arm 23, 24 in this embodiment. It could just as well be a crane arm. About the rotating device 25, the tools C can be pivoted forwards or backwards in an angular range ± α in the longitudinal direction of the track. When grading, a side plow blade 5 is adjusted in such a way that its rear small deflector plate 20 connects seamlessly to the flexible outer gravel deflector plate 19 of the middle plow in the working direction. In the drawing, the ballast is pulled up from the left flank and conveyed to the right 21. The figure shows another advantage of the invention, namely that the right side plow E can be used to divert the ballast further down the right flank. This is another possibility that cannot be realized with conventional side plows.

figure 5 shows a schematic transverse view of a rotatable tool C with a telescopic arm 6, 7. The telescopic arm 6 sits on the rotary device 34, 26 which rotates about the vertical axis 27 and can be rotated downwards 13 via a joint. The range can be adjusted via the extension 12. The position of the tool can be adjusted to the gravel flank 2, 15 by rotating it in three spatial directions via a rotary joint D.
