Description

Technical field

The invention relates to a mobile device for the correction of track misalignment, which consists of a number of track-building machines, which are arranged one after the other in the track direction, independently of one another, for example a leveling tamping machine with tamping unit, lifting and possibly aligning device on the track. compaction of the ballast bed, wherein the tools of the machine for correcting the misalignment of the rail to the ideal position on the basis of the extended system are associated with the removal elements.

BACKGROUND OF THE INVENTION

Such mobile devices are known as mechanized train for incoming work and are intended in particular to ensure the exact position of the track, which requires very fast operation, as well as a longer lifetime of the correction work carried out on the track. Such rail-mounted machines are, for example, as shown in an article in the Railway Technical Review, 1977/78 pages 14 and 16, mutually merged into 25 mobile equipment, their outputs being balanced with each other, which makes it possible to stabilize the rail quite mechanically and with high economy, so in one go. In addition to the usual known leveling tamping and leveling machines, which are provided with a proprietary reference system, for example stabilization machines, gravel bed compaction machines, but also plows and screwing machines are incorporated into this mobile device.

It is known that, due to the limited length of the machine reference system, it is not possible to eliminate relatively long track waves or relatively long inaccuracies. In addition, this arrangement can adversely affect work results with a downstream machine, particularly in terms of the track position being created.

From ČSSR patent file no. It is also known to provide a reference system for measuring or correcting a track position in the form of a beam of laser beams, wherein the tools or adjusting bodies are provided with a sensor 45 responsive to the beam of laser beams and this sensor can be associated with different machines. The laser beam transmitter or the laser beam receiver is in this case arranged on a mobile track construction machine, in particular on a leveling tamping and leveling machine, with which it also moves.

These machines have proven to work well in practice, but they are relatively expensive and are not always robust enough for practical use.

From Austrian patent no. No. 353,819 and the Czech-55 Slovak patent no. 185 610 are also known separately mobile machines with their own fixed position system, for example mobile compaction or ramming machines, or mobile gravel bed cleaners. The tools of these machines are always connected to a sensing device which is oriented according to the wire reference line, positioned positively next to the track, which ensures the correction of the track position, or determines the value of the sampling depth during plowing or gravel sampling based on the nominal value. established by a straight line.

This known gravel bed cleaning machine has proven itself in practice.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a mobile device of the type described in the introduction, which would allow for a more complete and accurate alignment of the various mobile track construction machines which are used simultaneously.

The drawbacks are overcome and the object is solved by a device according to the invention, which consists in that the track construction machines are assigned a common reference line, located along sections next to the track and at least one tool and / or possibly one picking member of each machine. the track structure is connected to a sensing device designed to sense the reference line, the length of the reference line being at least twice the total length of all track building machines arranged one after the other in the longitudinal track direction.

The main advantage of the device according to the invention is that its construction is particularly simple and yet robust. In addition, in particular, the advantage is that any disturbing effect on the work result is reliably avoided, even if several track construction machines of different types are used immediately in succession. In addition, the track's accuracy in terms of its location in terms of improvement and correction will be increased. In particular, by combining the features of the invention, for the first time and surprisingly simple means, the devices and tools for the various jobs assigned to the various mobile machines independently of one another can be aligned so that the track is behind the last track building machine, even when the gravel is completely restored. The ballast bed in the desired nominal position, especially on long track sections.

A particularly advantageous embodiment of the mobile device according to the invention consists in that at least one tool and / or optionally a pick-up element, one at a distance from a moving track construction machine, for example a leveling tamping machine and one independently therefrom and continuously (nonstop) along the rail of the mobile machine. For building a track, for example a gravel bed cleaning machine, it is connected to a sensing device designed to sense a common reference line.

This allows for the first time the dependence of the track spacing of a mobile and continuous (24-hour) mobile track construction machine on a single common reference line, which makes it possible to achieve even different track construction machines with respect to their technology by very simple means of high identity work without interfering with each other.

According to a particularly expedient embodiment of the mobile device according to the invention, the tools and / or the removal elements, such as gravel bed cleaning machines, are arranged as the first machine in the working direction and provided with a cutting chain tool, a lifting tool and a straightening tool. the spacing of the mobile leveling tamping machine with the tools for lifting and lateral alignment as well as the continuous (nonstop) mobile stabilizing machine with the track-picking vibrating tools connected advantageously to the consecutively designed sensing devices for sensing the common reference line.

This more or less basic arrangement for the so-called mechanical work-pass train, which combines various track-building machines, provides a substantial increase in both the accuracy and the avoidance of each other when constructed according to the invention compared to the prior art without a common reference line. adversely affecting the work performed.

According to a further advantageous embodiment of the mobile device according to the invention, the tools and / or removal organs are as a leveling tamping machine, arranged as the first machine in the working direction and provided with a tamping unit, movable in the working direction and lifting tools, as well as a gravel bed cleaning machine. as well as another leveling tamping and leveling machine connected thereto with lifting and leveling tools and a subsequent stabilizing machine with vibrating tools, connected preferably to correspondingly designed sensing devices for sensing a common reference line.

This special design and arrangement, in particular in connection of a gravel bed cleaner with a leveling tamping machine, also allows the machining of a track where the gravel bed conditions are unfavorable, for example, a track with only a small amount of gravel. The accuracy that can be achieved with this mobile device can be achieved with virtually every desired gravel bed during leveling of the track, independently of the work involved in cleaning the gravel. This makes it possible to create sections of the track that have only a small gravel bed height, in a single operation from cleaning to stabilization and with high precision, so that the predetermined threshold or undesirable values are not exceeded during the required lifting of the track. track deformations.

A particularly simple and robust embodiment of the mobile device according to the invention consists in the fact that the common reference line is formed along the rail arranged by a wire-wearable tension line placed next to the rail and that each of the milestones is provided in the upper The guide means is guided by a free passage of the sensing device which is laterally and vertically adjustable in the guides and which is adapted to hold the wire in the free passage of the sensing device.

This embodiment is particularly useful for rough railway operation, since the reference line, which is formed of a stretched wire, but which can also be formed of a rolled-up steel strip, meets all the requirements imposed on it. In practice, the spans of the individual milestones are chosen so large that they do not exceed the required length of the wire relationship systems in the known individual machines, and in particular not so long that impermissible overhangs can occur. In addition, the local assembly and disassembly of the common wire relationship system along the sections according to the invention can be created quickly and reliably without the need for additional auxiliary means, while at the same time ensuring a smooth and accurate passage of the movement of the individual sensing devices.

A further advantageous embodiment of the mobile device according to the invention consists in that the common reference line is formed in one piece by a modified wire reference line, fastened by its ends optionally in both longitudinal track directions on each landmark by means of a winding device or tensioning device.

This arrangement is particularly useful and advantageous for a mobile device having only two, three or four different track construction machines and in which it is not necessary to produce an overall length that is too long.

According to a further feature of the invention, it is also possible to modify the common reference line so that it is formed of a two-piece wire reference line, fixed by its ends, optionally in both longitudinal track directions on each landline provided by the winding device or tensioning device.

This embodiment is particularly suitable for a mobile device having a relatively large number of track construction machines. In addition, in this relationship, it is possible to prepare the second rail section independently of the first and vice versa, so that the entire device can operate continuously and continuously.

DETAILED DESCRIPTION OF THE INVENTION

The traveling device 1 shown in FIG. 1 and 2, the gravel bed cleaning machine 3, which is arranged as the first machine in the working direction shown by the arrow 2, has a leveling tamping machine 4 connected thereto and a stabilizing machine 5 arranged behind each of these machines. , 4 and 5 form a so-called mechanical train for passage processing and are traversable by means of conventional bogies on a track 8 consisting of rails 7 and transverse sleepers 6, their respective tools and / or removal bodies being oriented to improve or correct track position, as will be described in more detail below, by means of a positionally fixed wire reference line

10, which is arranged next to the track 8 and can be staggered in sections by means of landmarks 9.

The continuous (non-stop) traveling machine 3 for cleaning gravel bed has a device with lifting tools

11, an elevated rail gripping an endless tool 12 with a cutting chain belonging to the cutting device and which can be adjusted by means of the lifting drives 13 both vertically and possibly in its inclined and working direction rearwardly adjustable by the lifting drives 14 with the alignment tools 15. The cutting tool 12 is connected to a sensing device 16 for sensing the nominal position determined by the wire reference line 10, which is connected to a control device 17 located on the machine by means of a control line. The control device 17 is further connected by a control line preferably provided with a matching device 15 connected by a sensing device 16. By means of this gravel bed cleaning machine 3, after lifting the rail grate, it is removed or added by a cutting tool 12 depending on the sensing device 16 after the common wire line 10, the gravel to a predetermined level and possibly a transverse slope, whereby the gravel on the nets is cleaned in a known manner and then discarded separately. The leveling tool 15, which is operable by the control device 17 cooperating with the sensing device 16 and the common wire reference line 10, then adjusts the bed gravel so as to achieve the desired seating of the rail grate.

As shown in FIG. 1 and 2, the leveling tamping machine 4 of the mobile device 1, which follows the gravel bed cleaning machine 3 in the working direction, is movable along the track 8 for tearing the transverse sleepers 6 in the working direction according to the arrow 2 at intervals. This leveling tamping machine 4 has, for each rail 7, a tamping unit 18 which is adjustable in height and which is provided, in particular, with suction and vibrating tamping tools, as well as an upstream device which is provided with lifting and lateral leveling tools 21 associated with hydraulic a lifting member 19 and a hydraulic lateral balancing drive 20. Between the tamping unit 18 and the lifting and balancing device, a pick-up member 22 is provided for each rail 7, which generally consists of a wheel guided on the rail 7 and height adjustable on the machine chassis frame. which is connected to it and extends as far as the wire reference line 23 associated with it and determining the nominal position. A lifting device 24 is associated with the lifting and lateral alignment tools 21 for each rail 7 and a picking device 24 is associated with the removal body 22. By means of this leveling tamping machine 4 the rail 8 formed by the rails 7 and the transverse sleepers 6 is raised and possibly laterally moved by lifting tools 21 and lateral alignment in a conventional manner according to the co-wired wire reference line 23 and the actuating device 25. By means of the sensor device 24 associated with the tools, a sensor line 24 for sensing the nominal sensing device 24 slides along the longer track sections. position, to create a continuous alignment with the values provided by the control on the ground along with the moving wire reference line 23. Likewise, lifting and eventually moving the track 8 to the desired nominal position is possible only via By means of the sensing device 24 on the basis of the common wire reference line 10. The tamping unit 18 is tamped by the tamping unit 18 in the desired position by the lifting and lateral alignment tools 21 by feeding and vibrating the tamping tools, thereby securing it in the desired position.

In particular, in FIG. 2 clearly shows and continuously (non-stop) mobile stabilization machine 5, which is mobile on the track 8 independently of the leveling tamping machine 4, has two in the longitudinal direction of the track 8 in succession 5 on the machine chassis frame arranged vibrating devices with vibrator tools 27 with respect to the chassis frame of the machine, height-adjustable and connected to a hydraulic lowering drive 26. The vibrator tools 27, which as gripper pulleys handle both rails 7 on both sides and which can be fed into lateral vibrations in particular, are adjustable in height and laterally by and are connected to a conventional co-moving reference system for selectively lowering or stabilizing the position of the track 8 and being connected to the control device 28. To the vibrator tools 27, preferably in each case between two pairs of vibrator tools 27 7, associated with the pick-ups 29, which are connected to the pick-ups 30, both to secure the position of the two rails 7 and to pick up the nominal position determined by the common wire reference line 10. Each of these pick-ups 29 is also connected to the control device. 28. With the stabilizing machine 5, a track 8 which has previously been cleaned and whose bed has been leveled in accordance with the common wire reference line 10, or which has then been lifted and tamped on the basis of the common wire reference line 10 and possibly the wire reference line 23 , positioning and stabilizing in accordance with the alignment of the track 8 to the appropriate position, while sliding the sensing device 29 along the common wire reference line 10, provides accurate values for the nominal position, which can be compared with known actual values in the respective track sections 8.

The common wire reference line 10 is, as is clear from FIG. 1 and 2, tensioned on a number of milestones 9 positioned one after another in the longitudinal direction of the rail 8 and adjacent thereto. These fastening or marking milestones 9 are located next to the track 8, for example embedded in the plan and are spaced apart from one another so as to reliably prevent unwanted overhang of the common wire line 45 10. The position of the common wire line 10 is at least as large as twice the total length of all the machines placed one behind the other, i.e. the gravel bed cleaning machine 3, the leveling tamping machine 4 and the stabilizing machine 5, as is particularly well seen in FIG. 3, in which the individual machines are shown in an even more schematic embodiment for an even better understanding.

The fixing or marking landmark 9, which is shown to a greater extent in FIG. 5 and 6, is formed by a guide member 31 housing a common wire 10, which guide member 31 is designed to allow complete passage of the sensing devices 16, 24 and 29, which are designed as rolling sensors and preferably are arranged identically. The guide member 31 is laterally and vertically adjustable by means of guide 32 so that the common wire 10 can be brought to the desired height and lateral position by the guide members 31 of each landmark 9. For the assembly and disassembly of the 65 common wire reference line 10 in sections, a winding device 33 and a tensioning device 34 are located on each landmark 9, thereby allowing the ends of the common wire reference line 10 to be optionally rolled or unwound in both longitudinal directions. and fasten.

Each landmark 9 is essentially formed by a pile 35, at the upper end of which a guide member 31 is fastened, having at its upper end a groove depression with a sharp or right angle to accommodate a common wire reference line 10, the selected angle corresponding to the rolling sensor sensor 16 It is essential that an unrestricted passage of the rolling sensor is provided through the respective guide member 31. To guide the wire of the common wire 10, each guide member 31 has an insertion opening 36, while securing the rolling pulley of the winding device 33 and the tensioning device. 34, a reciprocating locking device 37 is provided. On horizontal and vertical guides 32, locking devices 38 and 39 are provided in the desired lateral or height position to secure the guide member 31 connected to the pile 35.

The landmark 9 shown in FIG. 4 corresponds to that shown in FIG. 1, the front end of the wire 10 is anchored in this landmark 9. Similarly, the rear end of the one-piece common wire 10 is anchored in the landmark 9 shown in FIG. 1 shown on the left side. Between these two milestones 9, the other milestones 9 arranged only serve to hold and guide the common wire line 10 through the respective guide members 31.

Another example of a traveling device 40 according to the invention, which is shown in FIG. 6, a leveling tamping machine 41 is positioned as the first machine in the working direction, followed by and connected to a gravel bed cleaning machine 42, and both machines 41, 42 are another leveling tamping and leveling machine 43, which is spaced apart if a continuous stabilizing machine 44 is attached thereto. The leveling tamping machine 41 provided with lifting tools is coupled and movable together, as in the embodiments of FIG. 1 to 5, with a cutting-edge tool and a leveling tool included in the gravel bed cleaning machine 42. The tamping unit of the leveling tamping machine 41, which is height adjustable, is also provided with suction and vibrating tamping tools and is displaceable on the machine frame in the longitudinal direction of the machine, allowing the forward leveling tamping machine 41 and the machine 41 to move forward. 42 for tearing the gravel bed to tamp the individual transverse sleepers.

The leveling tamping and leveling machine 43 and the stabilizing machine 44 are, as in the embodiments of FIG. 1 to 5, each having a tamping unit for each rail, a device with lifting and alignment tools, or a device with vibrating tools and corresponding removal bodies. The tools and removal organs of the four machines 41, 42, 43 and 44 are quite the same as in the embodiments of FIG. 1 to 5 are provided with sensing devices 45, or these sensing devices 45 are associated with lifting and leveling tools and vibrating tools. These sensing devices 45, designed as rolling sensors, are intended for sliding or sensing the nominal position on, in this embodiment, the two-part wire reference line 46, 47.

As shown in FIG. 7, the respective ends of this two-part wire reference line 46 and 47 are inserted into the insertion opening 48 of the landmark 49 and further tensioned by the winding and tensioning devices and fixed to the landmark 49 substantially as in FIG. 4 and 5. The landmark 49 is thus formed as described in FIG. The sensing devices 45 associated with the leveling tamping machine 41, the gravel bed cleaning machine 42, the leveling tamping and leveling machine 43 and the stabilizing machine 44 can thus pass from one end of the wire to the other front end of the wire. As the last sensing device 45 moves at the end of the front wire reference line 47, the rear wire reference line 46 can already be removed and tensioned to a further landmark 49 arranged in front of the front wire reference line 47. at a distance that corresponds, on average, to the length of the machine, the total length of the two-piece wire reference line 46, 47 corresponding to at least twice the total length of all the machines 41, 42, 43, 44 located one after the other.

The traveling device 40 shown in FIG. 6 and 7 allows the leveling tamping machine 41, which is mounted as the first machine, to lift and tample the track before the gravel bed cleaning machine 42, allowing the gravel bed to be cleaned at a relatively low height so that the track does not deform too much with a big lift. All these corrections in conjunction with the leveling, eventually lifting and lateral displacement of the ballast track can be controlled and adjusted to the desired nominal position by means of a common two-piece wire reference line 46 and 47.

The operation of the device according to the invention for improving or correcting the track position in connection with FIG. 1 to 5.

Before the mobile equipment I is installed in the gap between the trains, the fastening or marking milestones 9 required for a common one-piece wire reference line 10 can be driven into the plan next to the track 8 and by means of guidance and in accordance with the track design in the nominal position them in height and side. In this case, the distance of the spacing 9 between each other should suitably correspond to at least one machine length. Thereafter, the common wire reference line 10 is tensioned by the winding devices 33 and the tensioning devices 34 from the last rear landmark 9 considered in the working direction of the traveling device 1 to the foremost landmark 9 while being placed on the guide members 31. In this operation Once the individual pick-ups 16, 24, 29 of the various track-building machines 3, 4, 5 have reached the tensioned and in accordance with the nominal track position 8 of the aligned wire-like reference line 10, sensing devices 16, 24, 29 designed as rolling sensors, in particular as double rollers with a rim, are placed thereon. In a further process, any deviation from the position of the tools 12, 15 or removal bodies 22, 30 connected to the sensing devices, with respect to the wire reference line 10, is converted into a corresponding electrical signal which is fed via control lines to the respective actuating devices 17, 25, These actuators 17, 25, 28 are each connected to the hydraulic actuator circuits of the actuators 13, 14, 19, 20, 26 controlling the individual actuators or the tools 12, 15, 21, 27, and operate as long as no deviation from the nominal position or the desired position is ensured by the respective sensing device. In this case, for example, the pick-up device 16 of the cutting tool 12 can be adjusted so that it does not emit a signal when the desired picking depth is reached.

As soon as the front gravel bed cleaning machine 3 reaches the end of the wire reference line 10 and the leveling tamping machine 4 and the stabilizing machine 5 stop closely one after the other, the entire vehicle 1 is stopped. the rear and front winding devices 33 and the tensioning devices 34 and, if possible, slide or tension on the guide members 31 as long as in the working direction indicated by the arrow 2 until the rear end of the wire reference line 10 reaches space immediately behind the sensing device 29 of the stabilizing machine 5; who is deployed last. The two ends are again fastened and tensioned to the winding device 33 and the tensioning device 34 of the lands 9 provided in this area. Since the front milestones 9 have been aligned and leveled during the operation of the mobile device 1 in accordance with the desired course of the track 8, the interruption of work required to move the common wire line 10 can only be very short.

The described embodiments do not in any way constitute a limitation of the invention, since various variations are possible within the invention, particularly in terms of individual technologies in connection with the choice of different ones, independently of each other, along the track of mobile track construction machines. It is also possible to use any suitable mechanical means on the reference line which is suitable for particularly rapid assembly and disassembly. Thus, for example, a relatively rigid, for example also a rod-like reference line, or a suitable guide with rigid side walls, in particular also in conjunction with a guide ruler or the like, may be used. Also, the special design of the sensing devices can be varied in accordance with the other kind of reference lines used. It is essential that these parts are both as simple and robust as possible and that they are suitable for achieving adequate accuracy and relatively quick assembly and disassembly.
