Description

451 471 2 rail stabilization units, which via their own wheel racks which can be driven into the track and which can be formally engaged with both rails of the track and with respect to the working direction are arranged on the chassis frame behind the padding unit and whose tool frame can be set in substantially horizontal oscillations. piston-cylinder drive means connected to the chassis frame can be actuated with substantially vertical load forces, as well as with a device for tool control and at least one leveling and possibly directional reference system.

According to DE-OS 5 152 708, a drivable rail stopping, leveling and straightening machine with a chassis frame located on propulsion devices located at a distance from each other is previously known, which machine stopping, rail lifting and straightening units are arranged between these two propulsion devices on the chassis frame. Each padding assembly is provided with a tool carrier height-adjustable by means of a drive means, by means of adjusting and vibrating drive means pairwise adjustable and vibrable, in macadam-insertable stopping tools.

The rail lifting and straightening unit arranged in front of the padding unit and separately mounted on the chassis frame and provided with lifting and directing drive means is connected to a device for tool control and a leveling and a direction reference system. After the stop assembly in the working direction, a rail stabilization assembly is further arranged on the chassis frame, which via its own wheel racks can be formally engaged with the two rails of the unit, which tool frame can be forged by means of vibrations in substantially horizontal oscillations and by means of carbon chassis. can be affected with mainly vertical load forces.

With this known rail stopping, leveling and straightening machine in connection with the rail stabilizing unit arranged after the stopping units, an advantageous one is created, one immediately after the other following arrangement of stopping tools and horizontally in swing and 451 471 vertically loaded tools for stabilizing rail thereby achieving a favorable overlap of the working ranges of these tools for the efficiency of both machining tools.

According to DE-OS 3 106 754, a rail stopping machine with lifting and straightening tools is also known, which machine is provided with a tool carrier designed in the same way as a drawbar chassis with tools for lifting and straightening the groove.

The tool carrier of the stuffing unit and the tool carrier with these rail lifting and straightening tools are stored on the chassis frame, separated from each other. This drawbar-like tool carrier is further articulated with a free end via a cardan joint and with its other end via lifting drive means on all sides pivotable at the chassis frame. For guiding the tool carrier end located opposite the gimbal joint, a pair of lifting tool pairs is arranged between the two lifting tool pairs. flange auxiliaries mounted on a common shaft. This flange aid serves at the same time as a guiding tool and is connected to a guiding drive means.

This machine has been particularly distinguished for a safe and stable gripping of the track and for an advantageous automatic centering of the rail lifting and straightening tools, especially in rail bends.

The invention now has for its object to provide a drivable rail stopping, leveling and straightening machine of the type initially described in connection with a rail stabilizing unit for compressing a track macadam bed, which machine is even more advantageous in its construction and creates a better adaptation. of all tools for rail machining laterally and vertically.

What characterizes the invention is that the stopping and rail lifting units with associated drive means as working unit are arranged on a common own tool support frame, which with one end via a simple propulsion device designed as support and guide means and serving as a free steering shaft can support the track and with its other end as a support is hingedly connected to the chassis frame, and wherein the rail stabilizing unit is arranged between the work unit and nearby, seen in the working direction of the machine, machine propulsion device located after this unit.

Such a designed, with a rail stabilizing unit combined rail stopping, leveling and straightening machine not only creates the possibility of an advantageous and overlapping of the areas of action of the stopping and rope stabilizing unit, but at the same time insures through the arrangement with the stoppers designed as a work unit. and the aiming assemblies on a separate tool support frame an independent, precise post-guidance of these assemblies and the tools arranged on them to the appropriate lateral and vertical extension of the groove. Then further in each stuffing unit usually four to sixteen or t.o.m. thirty-two stop rods simultaneously or substantially simultaneously must be directed at each rail string, this automatic centering of the units is of great advantage for efficient and interference-free operation.

Advantageously, according to another embodiment of the invention, the common tool support frame of the work unit for a stepwise work feed in the machine direction - in the continuous non-stop feed of the shrimp mobilization unit and the machine - is connected to a hydraulic length adjustment drive device hinged to the chassis frame. than a machine designed with these features creates in particular the possibility of continuous step-by-step padding and continuous stabilization, whereby in particular an exact track position and a good even compaction of the macadam bed is achieved. In addition, the continuous driving of the machine while avoiding many energy-intensive starting and braking processes allows the operator to concentrate with increased driving comfort mainly only on the continuous stepwise feed of the work unit, ie of the tool support frame with the stuffing, rail lifting and straightening unit.

According to a further embodiment of the invention, the common tool frame of the work unit is designed as a drawbar chassis, which at its end located closer to the stuffing assembly is provided with a simple propulsion device suitably designed as flange aids and between its other end and the stuffing assembly 451 471. a longitudinal support beam for longitudinally displaceable storage at its support point on the chassis frame, wherein the tool support frame is hingedly connected to the chassis frame on all sides via the hydraulic adjusting drive device. This creates a constructively especially simple and compact arrangement of the padding, rail lifting and straightening unit at the machine main frame with good freedom of movement of the pre-tool support frame both in the longitudinal direction of the machine and its transverse direction.

Accordingly, according to another feature of the invention, the longitudinal support beam - for slidable storage of the working unit on a guide arranged on the chassis frame, formed by rollers or the like - is formed with a square or double-T-shaped profile cross-section. This simple and robust operation is advantageous especially for a continuous workflow.

A further feature of the invention is that the tool frame, which is also designed as a drawbar ohassi, is connected to the rail lifting and straightening unit guided by flange rollers on the track, is connected to the tool support frame of the work unit via the rail lifting and straightening means and is hingedly connected to its beam end. the longitudinal bar beam of the common tool support frame. The design of the rail lifting and straightening assembly, which is already very well known in rail stopping machines of conventional construction, as a drawbar chassis, is particularly advantageous for a machine according to the invention, since the available space under the tool support longitudinal beam in the work unit for placing the rail lifting and straightening unit is fully utilized. no extra construction space on the side is required.

According to a further embodiment of the invention, the rail stabilizing assembly in the working direction is arranged at a distance behind the working unit and the hydraulic adjustment d-worgan setting path for a simple stepwise advancement of the working unit from the stopping point to the stopping position. tone to double the sill distance. This arrangement of the rail stabilization unit at a distance behind the work unit ensures during operation a particularly good overlap of the areas of action of the stop and rail stabilization unit. 451 471 Furthermore, it is ensured that the continuous non-stop advance of the machine does not have to be interrupted when a stopping process, e.g. due to severely hardened macadam bed, requires slightly more time than normal. Due to this abundant increase in the setting path, the stopping process, e.g. by lowering the upholstery tools twice, it is completed in the proper order, after which the tool support frame with the work unit is quickly moved to the next upholstery point by means of the transfer drive device. Such a machine meets almost all requirements in practice for an efficient, easily operable and suitable for a trouble-free lasting operation, with a rail stabilization unit combined rail stop, leveling and straightening machine for a continuous non-mapping advance.

According to a further feature of the invention, the piston movement of the adjusting drive means designed as a double-acting hydraulic piston cylinder is advantageously controllable via a valve device or the like with the rail stabilization assembly synchronously and opposite to the continuous feed movement of the machine resp. its chassis- ram. For such a hydraulic control of the relative movement between the machine main frame and the tool support frame in the work unit, different, partially known and in practice fully recognized elements or means are available.

According to a particularly suitable embodiment of the invention, the stopping, lifting and straightening unit having the working unit and the rail staging unit arranged with respect to the working direction behind this working unit are arranged inside two spaced apart machine propulsion devices. The positioning of the stuffing, lifting and straightening units between two spaced apart machine propulsion devices which has been used practically for the past ten to fifteen years in the hitherto known drivable rail stopping, leveling and straightening machines has in practice become very well known. and is also of particular advantage when it comes to the use of this newly created work unit in connection with the rail stabilization assembly with regard to the precision and efficiency of the machine. ages-t, - ~ - f ». ,. 451 471 7 According to a further feature of the invention, the vibrating drive means of the padding assembly and the vibrations of the rail stabilizer assembly are designed for a vibrational movement of the padding tools in phase with the tool frame of the rail stabilizer assembly. With such a design, ie. in the case of oscillation generation of the macadam in phase in the overlapping areas of action for the upholstery and stabilization tools, in particular in continuous non-stop work, further reinforcement and smoothing of the compression over the entire macadam processing area is created.

Finally, according to a further feature of the invention, the piston-cylinder drive means are adjustable for vertical loading and resp. or the vibrations of the rail stabilization unit via the control device and in particular by means of a leveling reference system, which also cooperates with the work unit, in particular the rail lifting and / or the directional unit. With such a design, the extent of the rail lowering through the stabilization process according to the height difference in relation to the child level determined by the leveling reference system in the padding area can be regulated in such a way that the height of the work unit and rail stabilizing unit finished with the workpiece. pre-calculated should-height stretch. When using a leveling reference system common to the rail lifting and stabilization tools, the calculation and also the presetting of the required track height with the aid of a control or regulation device belonging to a reference system is particularly simple.

The invention will be described in more detail in the following with reference to two exemplary embodiments shown in the drawing. Fig. 1 shows a schematic side view of a sifting, rail stuffing, leveling and straightening machine with a rope topping assembly according to the invention and Fig. 2 a schematic plan view of the machine according to Fig. 1. Fig. 5 shows a partly schematic side view of a two-sill, rail stopping, leveling and straightening machine with rail stabilization unit.

Den i fíg; 1 and 2, and the straightening machine 1 is provided with a chassis frame 6 which can be run by means of 2 machine propulsion devices 2.5 on one of the rails 4 and sills 5. The working direction of the machine 1 is indicated by an arrow 7. For power supply a drive and power supply device 8 is arranged and for control a control device 9.

The machine 1 is equipped with a leveling reference system 10, which for each rail has a clamping wire 11, the front end of which is guided via the propulsion device 3 to the uncorrected groove and the rear end of which is guided via a sensing means 12 to the corrected groove. The working belts 15, each consisting of a padding assembly 15 and a rail lifting and straightening assembly 14, form a work unit 15 with associated drive means and are arranged on a common, separate tool support frame 16. This is designed as a drawbar chassis and supports with one end via a support and guide means designed and serving as a free steering shaft simple propulsion device 17 on the track and is with its other end hingedly connected to the chassis frame 6. legs connected to the chassis frame 6 are designed as longitudinal support beam 18 and rest via a bearing point 19 on the chassis frame The bearing stand 19 is designed as a roll guide, which comprises two rollers 20 abutting on the underside and two against the upper side of the longitudinal support beam 18, provided on both sides with guide flanges, are rotatably mounted at the chassis frame 6 and are formed with square or double T- shaped profile cross section. A lateral play between the longitudinal support beam 18 and the guide flanges of the rollers 20 allows a lateral pivotability of the tool support frame 16 around the bearing rack 19. The tool support frame 16 and the chassis frame 6 are arranged via a long-acting piston-cylinder device hydraulically longitudinally connected connecting means 21. . Each padding assembly 13 is provided with padding tools 22 which can be inserted into the macadam, which by means of known hydraulic eccentric vibration drive means are movable in vibrating movements parallel in the longitudinal direction of the rails. However, it is also possible to connect a vibrating drive means 25 rotatable about an axis extending in the longitudinal direction of the rails, whereby the stuffing tools 22 are movable in vibrating movements transversely to the longitudinal direction of the rails. Approximately at the longitudinal center of the upholstery assembly 13, one is provided with fastening means for the rails, e.g. screws, cooperating inductive sensor 24 on the tool support frame 16.

The rail lifting and straightening assembly 14 of the machine 1 is provided with a tool roller 27 shaped with flange guide rollers 25 on the track and with lifting rollers 26 pivotable under the rail head, which tool frame 27 is designed as a drawbar chassis and is hingedly mounted at the tool frame. 16 longitudinal support beam 18. The tool frame 27 is further articulated to the tool support frame 16 via rail rail drive means 29 and direction drive means 30 to the rail lift and direction assembly 14. Arranged on the tool support frame 16 for each rail 4 is a lifting unit which can be raised and lowered by means of height-adjusting drive means. In order not to prevent the height-adjusting means 31, the two beams 32 provided with upwardly directed recesses 32 are provided with longitudinally extending lines. indicated recess. In the area between the padding units 13 and the rail lifting and straightening unit 14, a sensing measuring device 34 controlled without play on the track is arranged, to which a e.g. a measuring sensing means designed as a rotary potentiometer, which cooperates with the corresponding clamping wire 11 in the leveling reference system 10 for determining the difference-in-height position difference of the track.

Between the work unit 15 and nearby, seen in the working direction of the machine, hereafter arranged machine propulsion device 2, a rail stabilizing assembly 36 is connected via piston-cylinder drive means 37 to the chassis frame 6. The rail stabilizing assembly 36 is impregnated with its own flange guide rollers 38. and pivotable gripping rollers 39, which can be molded into engagement with the underside of the rail heads on the outside of resp. rail 4. In order to generate transversely to the longitudinal axis of the groove, mainly horizontal oscillations, vibrators 40 are arranged. The oscillations and the load applicable by the piston-cylinder drive means 37 to the rail stabilizing assembly 36 are transmitted in the direction of the arrow 41. via the guide and gripping rollers 38, 39 brought into engagement with the rails 4 in a form-fitting manner.

The machine 1 is equipped with various attachment devices, which enable an automatic control of the various movement functions during continuous non-stop advancement of the machine with its chassis frame 6 and stepwise advancement of the tool support frame 16 with the stopping assembly 13 from stopping point to stopping point. These devices comprise a control device 9, a valve device 42, by means of which the hydraulic length adjustment drive means 21 is arbitrarily pressure-operable in both directions of movement.

The valve device 42 is connected to three different attachment devices for control. One of these devices is a path measuring device 43 constructively connected to the sensing means 12, which for each unit of the feed path traveled by the machine emits a control pulse to the valve device 42, which regulates the supply of pressure medium to the right cylinder chamber in the hydraulic length adjusting means 21 synchronously. and in the opposite direction to the feed path of the machine, so that the tool support frame 16 with the stuffing units 13 until the end of the stuffing process remains in place and centering position to the awl to be packed under. At the moment of lifting the stop assemblies 13, the valve assembly 42 is redirected, the left cylinder chamber of the hydraulic length adjusting member 21 is pressurized and the tool support frame 16 is advanced at such a speed that the stop assemblies are in centering position with respect to the next sill, to be packed under. When immersing the stuffing unit 13, the road measuring device 43 is set to zero at the same time, after which a new work cycle begins.

A similar movement occurs when using a relative displacement between the tool support frame 16 and the chassis frame 6 measuring wire strain potentiometer 44, which is attached to the side of the tool support frame 16 on a beam 32 of the chassis frame 6. In this case, the piston movement is controlled in the the hydraulic length adjusting drive means 21 in proportion to the setting movement of a rod 16 connected to the tool carrier frame and the wire strain potentiometer 44 or the output voltage present as an analog signal in the wire strain potentiometer 44.

For controlling the valve device 42, an inductive sensor 24 cooperating with the rail fastening means is further provided. This remains neutral until it is in centering position in relation to the rail fastening screw in question. When deviating from its centering position, the inductive sensor 24 emits to the valve device 42 a control signal which changes the pressure medium supply to the hydraulic length adjusting means 21. Thus, the stopping assembly 13 remains in the centering position relative to the sill to be packed until the end of the stopping process. The rail stopping, leveling and straightening machine 1, which is equipped with the rail stabilizing unit 36 and the work unit 15 belonging to each rail and the rail lifting and straightening unit 14, can therefore be driven arbitrarily with the relative machine movable stopping, rail lifting and straightening units, with continuous non-stop advancement or with step-by-step advancement adapted to the sill distance.

In Fig. 2, a circuit 45 shown by dash-dotted lines illustrates the range of action in which the macadam is subjected to oscillations and compressed by the vibrational movements of the vibrators 40 in the rail stabilizing assembly 36.

The vibrating movement transverse to the longitudinal direction of the groove is shown by double arrows at the gripping rollers 39. The adjustably mounted stuffing tools 22 are set by the vibrating drive means in vibrating movements parallel to the longitudinal direction of the rails, the area of action of which is illustrated by a dashed, 13 circumferential assembly. As can be seen, the areas of action of the rail stabilizing assembly 36 and the two padding assemblies 13 are already folded over in their extreme, right-hand position. In the left, dashed end position of the padding assemblies 13, there is finally a total overlap of the areas of action of the rail stabilizing assembly 36 and the padding assembly 13. When the vibrating drive member 23 is put into operation, the vibrating transverse axis 22 and transverse axis 22 of the rails can be vibrated. the tool frame of the rail stabilizer assembly 36 achieve a vibration movement in phase.

The rail stuffing, leveling and straightening machine 46 only partially disassembled in Fig. 3 corresponds in all essentials - with the exception of the stuffing unit and the constructive dimensions thereby conditioned - to the machine already described in Figs. 1 and 2. This machine is provided with a chassis frame 49 movable on the track 48 by means of two spaced apart machine propulsion devices 47. In the working direction of the machine 46 with an arrow 50 in front of the rear machine propulsion device 47, a means is arranged by means of vibrators to substantially horizontal swingable displaceable rail stabilizing assembly 51 and one of a tool support frame 52 with a height-adjustable double stop assembly 53 for simultaneous packing of two adjacent slats and a rail lifting and straightening assembly 54 comprising work unit 55. This with one end of the groove in front and at the working end 55 supporting the other end towards the machine 46 is displaceable in the longitudinal direction of the machine by means of a hydraulic length adjusting drive member 56 which is hingedly mounted to the chassis frame 49 and a guide device 57 connected thereto via a cable. stepwise advancing the work unit 55 after completion of the stop The opening process during partial simultaneous lifting of the double-stop assembly 55 at the continuous non-stop feed movement of the machine 46 corresponds approximately to the three to four fi times the sill distance, so that with faster feed movement of the machine 46 an even larger capacity increase can be achieved.

The control device 57 can be actuated by an inductive sensor 59 attached to the tool support frame 52, a wire strain potentiometer 60 arranged at the chassis frame 49 and a path measuring device 62 constructively connected to a sensing member 61 for the stepwise advancement of the work unit 55. of the work unit 55 with the stuffing tool 53 of the double stuffing unit 53 immersed in the macadam is shown schematically with dashed lines.
