Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a tie tamper for simultaneously compacting the ballast under a plurality of sleepers on a track, particularly a tympah with no height adjustment and straightening, which includes a hokey frame that can run on a traveling device;
A tamping tool supported on a tamping tool frame or an intermediate support, and a height drive device, a vibration drive device, and a scraping drive device for driving the tamping tool are provided, and the tamping tools face each other in the longitudinal direction of the track. The present invention relates to a type in which the two tamping tools, each of which is movable and can be thrust together into the section between the sleepers, are designed as a pair of split-legged real-opening tools.

The advantage of a tamper tamping device of this kind, which is disclosed for example in DE 191 0 652, is that the tamping tool is arranged above and approximately straddles one of the sleepers and that the tamping tool is rammed by a pry-like movement. In contrast to other known tamping devices designed for compacting under sleepers, more space is available, especially structurally, for the arrangement of the tamping tools in connection with the connection with the drive device. be.

Another tamper tamping device disclosed in DE 24 26 841 is equipped with two tamping tool holders that can be driven up and down independently of each other. each have a split-leg real opening tool pair and a single tamping tool which is assigned to the outside of this tamping tool pair in the orbital direction, so that they can be moved one behind the other. It is now possible to work on the three sleepers placed at the same time.

A disadvantage of this type of tamping device is that the spacing between the sleepers is not always regular, so that during operation the tamping tool inevitably hits and damages the sleepers during its descent.

Furthermore, it is extremely difficult to monitor the tamping process from the operator's side.

This is because a large number of tamping tools are arranged one behind the other in the longitudinal direction of the track, making it difficult to locally position each tamping tool at a desired position. .

The intended tamping of the underside of at least two adjacent sleepers has traditionally been carried out in German Patent No. 1237
This was possible only with the tamping device disclosed in the specification of No. 157 (Japanese Patent Application No. 12345/1984).

In this tamping device, two pairs of tamping tools are arranged directly next to each other, and the two central tamping tools of both pairs of tamping tools can penetrate into the same section between sleepers. , forming a pair of open-leg type actual opening tools.

This allows the trajectory to be compacted very precisely and strongly.

This is because, during the compaction movement, the ballast is distributed very evenly and reliably from the area between the sleepers to below the sleepers that are adjacent to each other.

Therefore, uniform compaction sections and calibrated rail positions are obtained over a large length section of the track.

Another advantage of the known tamping device is that it tamps almost simultaneously under two sleepers adjacent to each other, so that the central pair of tamping tools only needs to penetrate once into one inter-sleeper section, and thus Its purpose is to significantly contribute to operator monitoring.

It is an object of the invention that, compared to the prior art, the ballast from the individual sleeper sections can be distributed better and more uniformly below the sleepers next to each other, especially over large length sections of the track. The object of the present invention is to provide a tamper that is guaranteed and also has the last-mentioned advantages of known tamping devices for simultaneously tamping under two sleepers.

The fundamental idea of the present invention is that the quality of the track can be improved by the track tamping method using the known tamping device for tamping the bottom of the last two sleepers, especially by the pair of central spread-type truss tools. We start from the understanding that at least about 50'1 can be obtained.

This is because in this case the central tamping tool pair only has to penetrate once into a given sleeper section, and the tamping tool pair with a single tamping tool rams step by step under one sleeper. This is because there is no chance of the trackbed being damaged by re-entry, unlike other devices.

The gist of the present invention that solves the above problems is to provide two pairs of spread-leg type protruding tools arranged one after the other in the longitudinal direction of the track so as to penetrate into the section between two sleepers and the section adjacent thereto. are supported on a common tamping tool support which can be driven up and down by means of a centrally arranged drive, forming a twin-leg real tamping tool unit with four tamping tools. This twin split-leg real opening tool unit is connected to one common tamping tool support, which is arranged on the tamping tool support in the center between both pairs of split-leg recess tools, via a scraping drive. It consists in being coupled to a vibration drive.

According to such a twin leg opening tool unit, it is only necessary to enter the twin leg opening tool unit once into the section between two adjacent sleepers, and as a result, there is no risk of re-entry. The evil shadow police are stopped from entering the roadbed.

Since the pair of open-legged protruding tools in the center has a relatively large volume, the ballast is compacted not only by scraping and vibration, but also by pushing this pair of tools, which have a relatively large volume, into the ballast. Effect can be obtained.

Because the pairs of split-leg truss tools are arranged one behind the other, the degree of compaction of the trackbed and the uniformity of compaction are increased, especially over large length sections of the trackbed.

A further advantage of the present invention is that it is only necessary to insert the spread-leg type projecting tool into the section between two adjacent sleepers, which not only makes monitoring easier, but also makes it easier to monitor the height drive device and the scraping drive device. Alternatively, an advantageous structure is obtained in connection with a vibration drive.

According to the present invention, since the twin-spread type actual opening tool unit is coupled to one common vibration drive device placed in the center between both pairs of split-leg type protruding tools, The leg-type actual opening tool unit can be configured with a relatively narrow width.
Installation is easy.

In one embodiment of the invention, all four tamping tools of the twin-leg real opening tool unit are each supported on their own pivot axis, which is provided in the tamping tool support at right angles to the longitudinal direction of the track. has been done.

In this way, a compact construction and an easily operational bearing type are obtained.

Furthermore, in a further embodiment of the invention, all said pivot axes are arranged in the central longitudinal region of the tamping tools, and the upper ends of all four tamping tools each
It is connected to a raking drive which is hinged to the tamping tool support.

According to this configuration, the transmission member and its control member particularly related to raking and vibration can be arranged in the center.

In a further advantageous embodiment of the invention, four hydraulic tamping tools, each hinged to the upper end of the four tamping tools, are provided in the vibration drive arranged between the two pairs of split-leg tamping tools. The scraping cylinder piston drive is hinged.

With this configuration, the twin split-leg type actual opening tool unit of this type consisting of two pairs of split-leg type protruding barrel-opening tools can be
The asynchronous compaction principle of the raking movement, which has been proposed since 2000, will be implemented.

Furthermore, in another advantageous embodiment of the invention, the twin-leg real opening tool unit, the elevation drive, the vibration drive and the scraping drive are each associated with one rail or rail side. In order to operate the pair of spread-leg type protruding tools independently of each other, they each form a common mechanical component.

In that case, either the pairs of split-leg type protruding tools arranged along one rail are combined into one such structural unit, or the pairs of split-leg type protruding protruding tools that correspond to both rails are combined into one configuration. This opens up the possibility of combining them into units.

In a particularly advantageous further embodiment of the invention, the longitudinal dimensions of the component units are equal to or greater than twice the sleeper pitch.

In this way, particularly advantageous space savings are achieved in relation to the other structural features of this type of titan tamper, and a twin-leg recessed tool unit, which operates independently of each other, can be positioned in the longitudinal direction of the track. Multiple locations can be placed.

In a further advantageous embodiment of the invention, all the pivot axes of the twin-legged recessing tool unit are arranged at the upper end of the tamping tool and each has a scraping drive in its longitudinal central region. and is connected in the upper end region to a vibration drive, and the vibration drive and the scraping drive are arranged on the tamping tool carrier.

Furthermore, in an advantageous embodiment of the invention, a scraping drive consisting of a pair of nut and threaded spindles with opposite spirals is provided for both pairs of split-leg opening tools.

This configuration can be used, for example, in Patent Application Publication No. 24 of the Federal Republic of Germany.
No. 26841.

In order to equalize the action of the twin-leg recessing tool unit and to increase the compacting action, in a further embodiment of the invention, the vibration drive device is designed to generate vibrations in phase. , each of the tamping tools in each pair of split-leg opening tools are vibrated in the same vibration direction, and both pairs of split-leg opening tools are vibrated in directions opposite to each other.

With this configuration, not only will a uniform tamping tool volume always penetrate into the ballast in each sleeper section, but also a very uniform tamping tool volume in relation to vibration and raking over a relatively long track section. The ratio is obtained.

In a further advantageous embodiment of the invention, the tamping tool or the tool holder below it or the twin recessed tool unit formed by the double recessed tool pair is arranged with respect to the track direction. It is movable or pivotable in a direction perpendicular to the longitudinal axis of the track via a hydraulic drive connected to each pair of split-leg opening tools located perpendicularly opposite to each other.

According to the invention, it is further provided that an additional tamping tool is inserted into the front region of the end of the sleeper located at least in the middle of the two pairs of split-leg opening tools, preferably of both adjacent sleepers. It is advantageous to place it opposite the split-leg type deep facing tool unit.
This maintains or increases the accuracy of the work achieved with the present twin-leg drawing tool unit.

When leveling a high-speed section with a tie pad according to the invention, a compaction device for compacting the ballast in at least the sections between adjacent rear sleepers and, if appropriate, the ballast in the front area of the sides or ends of the sleepers is provided. It is effective to place the compacting device opposite to this twin-leg type real drawing tool unit.

The invention will now be explained with reference to the illustrated embodiment.

A tie tamper 1 shown in FIGS. 1 and 2 for correcting height deviations and misalignment of the track is guided via a traveling device 2 onto a track consisting of rails 3.4 and sleepers S. .

A track lifting and straightening device 6, a twin-spread-type deep facing tool unit 7, and a tool unit 8 for compacting the ballast in the section F between sleepers are arranged on the vehicle body frame 5.

Furthermore, the damper 1 is equipped with reference threads 9, 10 for monitoring the height or lateral position of the track and for controlling the track lifting and straightening device 6.

The height and lateral position of the track is checked via electrical measurement value transformers.

The twin split-leg type deep facing tool unit 7 of the present invention has a number of split-leg type real opening tools 1 when viewed in the direction perpendicular to the track.
1, and each of these split-leg real opening tools 11 is composed of four tamping tools 12.13.degree. 14.15 located one behind the other in the orbital direction.

These four tamping tools 12, 13, 14, 15 are each combined into two split-leg real opening tool pairs 16.17 and are arranged on a common tamping tool holder 18. .

As seen in the working direction indicated by arrow A, the front split-leg type actual opening tool pair 16 has entered into the section between sleepers F1, and the second split-leg type actual opening tool pair 17 has entered into the section between sleepers F2. It's rushing in.

Each tamping tool 12, 13, 14, 15 is rotatably mounted in a central region on a tamping tool holder 18 about an axis extending transversely to the track;
The upper end of each tamping tool 12.13° 14.15 is connected to a common central oscillating drive 21 via a scraping cylinder piston drive 19.20 serving as scraping drive. .

The twin split-leg type deep facing tool unit 7 is a tamping tool 12.1
3.14.15 is connected to the tamping tool frame 24 via a height drive device 23 constituted by a cylinder-piston mechanism 22 in order to move it up and down.

Furthermore, as can be seen from FIG. 2, a total of eight open-legged protruding tool gaps 11 are combined into one common mechanical structural unit, and the whole can be moved up and down.

For example, in order to be able to perfectly adjust the position of the tamping tool 12.13.14.15 in the direction of the track as well as in the direction perpendicular to the direction of the track, especially on curved paths with a small radius of curvature, the tamping tool frame 24 is arranged with cylinders. It is connected to the body frame 5 of the titan tamper 1 via piston drives 25 and 26, and is movably or pivotably supported on a guide rod extending in the direction of the track and in a direction perpendicular thereto.

As already mentioned, the tamping tools 12, 13° 14.15
The ballast is pushed under the sleepers S1*S2*S3 through the ballast and compacted.

In order to further increase this compaction effect, in particular in the direction of the already compacted track sections, the car body frame 5
.

As shown in FIGS. 1 and 3, a tool unit 8 (see FIG. 1) that works within the section F3 between sleepers is arranged, and this tool unit 8 has a diameter of 4 when viewed in the direction perpendicular to the track. It has two compaction tools 27 (see FIG. 3).

Furthermore, the twin leg type drawing tool unit 7 has a sleeper S1. S2. A plurality of end-drawing tools 28 are placed opposite each other and protrude into the ballast in front of the end of the S3 (as viewed in the longitudinal direction of the sleeper), and these end-drawing tools 2
8 can be configured to be capable of raking movement and vibration by means of a unique raking drive device and, in some cases, a vibration drive device.

As can be seen in FIG. 3, the end contouring tool 28 is furthermore opposed to a side compaction device 29, which is equipped with its own vibration device for introducing vibration movements into the ballast.

In the embodiment shown in FIGS. 4 and 5, only four split-legged cylindrical tool gaps 30 are provided, viewed in the direction perpendicular to the track.

The spaces 30 between the two open-legged protruding tools 30 corresponding to the rails 3 or 4 each form one open-legged protruding tool unit 31, and the tamping tools are connected to each other via a height drive device 32. It is connected to the frame or body frame of the titanpa.

Via the schematically illustrated coupling mechanism, both split-legged barrel tool units 31 can be moved up and down together by means of a central elevation drive.

In order to be able to use the tamper according to the invention in a rolling machine, each of the tamping tools 30 is pivotally connected to a hydraulic swiveling drive 33, which swiveling drive 33 itself It is fixed to the tool holder 34.

As a result, as shown in FIG. 5, the individual tamping tools can be swiveled laterally, for example at track branch points where two rails are in close contact, i.e. at right angles to the track; As a result, the drawing tool can penetrate into the ballast next to or to the side of another rail or structural part that prevents penetration.

It is also possible to combine the two split-legged protruding tools 30 via their own elevation drive to form a twin split-legged real-cutting tool unit, and also to form a twin-legged real-cutting tool unit with its own swivel drive and its own vertical drive. A vibration drive device may also be provided.

In FIG. 6, the tamping tools 12, 13, 14 are mounted on the tamping tool holder 18 of the twin-legged real drawing tool unit 7.
15 are supported and these tamping tools 12.13
．． 14.15 is mounted approximately in its central region so as to be pivotable in the direction of the track about a pivot axis 35.36.37.38 extending perpendicularly to the track.

Both tamping tools pair 16. 17 4 tamping tools 12
．． The upper ends of 13.degree. 14.15 are respectively connected to the piston rods of the scraping cylinder piston drives 19.20.

The cylinders of these scraping cylinder piston drives 19, 20 are mounted on an eccentric shaft arrangement 39 forming a common vibration drive 21, which eccentric shaft arrangement 39 is connected to the tamping tool pairs 16 and 17. It is placed in the center between.

The entire tamping tool holder 18 can be moved up and down along two guide rods by means of a height drive 23, thereby making it possible to change its height relative to the vehicle body frame 5 or the tamping tool frame 24.

The elevation drive 23 is fixed to the tamping tool frame 24.

The tamping tool frame 24 is arranged on a guide rod 40 via which it is movable relative to the vehicle body frame 5 in the track direction.

For this movement, for example, a hydraulic cylinder-piston mechanism, a chain drive, a rope device or a similar mechanical drive, for example a threaded spindle device, can be provided.

Furthermore, two guide bars 41 are shown schematically extending in a direction perpendicular to the track direction, along which the tamping tool frame 24 is moved relative to the body frame 5 in a direction perpendicular to the track. It is possible to move to

The operation of the twin splitting tool unit of the present invention will now be described with respect to the tie tamper shown in FIGS. 1 and 6, and in particular with respect to the different compaction areas of the ballast shown by the various hatchings.

The tie tamper 1 is moved to a predetermined position, and the split-leg opening tool pair 16.17 is attached to the sleeper S1. S2. Once located within a certain area to be tamped S3, the tamping tool holder 18 is lowered by the height drive 23 and the tamping tool 12.13.14.15 is moved between the sleepers with a relatively high speed and force. It rushes into the ballast in section F1°F2.

The tamping tool 12.13.14.15 is equipped with a so-called ice ax, by means of which the tamping tool 12.13.
Despite the oblique movement of the 14° 15 or upper part of the tamping tool holder 18, the lower end of the tamping tool, which has entered the ballast, can carry out an approximately parallel raking movement.

The two lower pickle plates in the position shown in FIG. 6 have a relatively large volume, so that a relatively large ballast volume V is displaced during entry.

When the tamping tools are arranged at right angles to the track direction (see Figure 3), the two adjacent tamping tools 11 are It is advantageous if the gap of the tamping tool is smaller than the smallest ballast grain in the track.

In this way, this gap acts the same as a complete surface.

The ballast displaced from the upper area of the sleeper section F1MF2, especially already during the plunge, forms a highly compacted ballast area (area marked by arrow V), which likewise
Sleeper S1. S2. The ballast in the edge area of S3 is also significantly compacted.

This first sleeper S1. S2. Following the downward compaction S3, a forced raking movement of the compaction tool 12.13° 14.15 by means of the raking cylinder piston drive 19.20 is introduced.

The tamping tool 12.13.14.15 then moves from the position shown in solid lines to the position shown in broken lines.

During the plunging and raking movements, both tamping tools 12.13 or 14.15 of a respective tamping tool pair 16 or 17 are vibrated in mutually opposite phases by the vibration drive.

That is, the two tamping tools 12.13 and 14.15 each oscillate away from each other and then towards each other.

Vibrating plunge of the tamping tools 12.13.14.15 into the ballast and the respective adjacent sleepers S1. S2
．． Section F1 between sleepers on both sides of S3. The combination of displacement of a relatively large ballast volume into the depths of F2 and a subsequent forced raking movement by the hydraulic raking cylinder piston drive 19.20 allows sleeper Sl
s S2s The ballast in the area below S3, which is finely hatched with a thin solid line, is compacted.

The lower part of the sleeper S3, shown hatched with thick solid lines, has already been hardened by the tamping tool 12, and when the tamping tool 15 hardens the remaining lower part of the sleeper S, this part is already hardened. The area (hatched with a thick solid line) serves as a resistive support.

The formation of this resistance support is also aided by the compaction of the ballast during the penetration of the compaction tool into the sleeper section.

As a result, the range V indicated by the thin notches is compacted, and this range V allows the sleepers S1*S2s S
The movement of ballast from the compaction area below 3 into the sleeper section is reduced or prevented.

This compaction process is carried out using two pairs of open-legged real-opening tools.
Therefore, uniformly compacted and strong support portions are formed simultaneously under one sleeper S2 and under each adjacent sleeper 81*S3.

The twin leg opening type real opening tool unit 7 according to the present invention has a first
This method is effective both for concrete sleepers, shown by cross hatching in the figure, and for wooden sleepers, shown by broken lines.

Furthermore, according to the twin leg opening tool unit 7 of the present invention, even though the tamping tools 12.13, 14.15 only enter into the section F1°F2 between the two sleepers, Three sleepers sx, s2. The ballast below s3 is treated at the same time.

This reduces the labor of the operator during the monitoring of the forward movement of the tie pusher 1 and the manual control of the forward and downward movements of the tamping tool, since in each case only two sleeper sections are monitored during the plunging process. That's because you can.

Furthermore, the worker only has to position both pairs of split-leg type real opening tools 16.17 based on the sleeper S2 located in the middle of these pairs of split-leg type real opening tools 16.17. Positioning is easier.

When the raking movement process of the recessing tools 12, 13, 14, 15 is completed, these recessing tools are simultaneously moved upwards by the elevation drive 23.

This prevents any negative effects on the already compacted ballast area.

Furthermore, by using a hydraulic scraping cylinder piston drive device, the recess tool 12.13.14.15
Asynchronous raking movements are guaranteed.

This is because, according to the cylinder piston, it is possible to apply a raking motion to each recessed tool until the required raking pressure, in other words, the desired degree of ballast compaction is obtained for each recessed tool. Because you can.

In short, the end of the raking movement is independent of a predetermined stroke, but is related to a predetermined final raking pressure.

Therefore, even if the momentum of each recessing tool is different, the ballast on the trackbed can be uniformly compacted by this asynchronous scraping motion.

Another embodiment of the twin-leg type recess tool unit of the present invention, which is equipped with a recess tool that performs a synchronous scraping motion, is shown in FIGS. 7 and 8.

A vibration drive device 46 is supported on the recessed tool holder 43 at the center between the two pairs of spread-type actual drawing tools 44°450.

The upper ends of the recessed tools 47, 47, 48, and 48 forming the split-leg type actual drawing tool pair 44, 45 are attached to the eccentric shaft forming the vibration driving body 46 via a fixed connecting member. each of which is coupled to one of two eccentric arms supported on the.

In order to pivot the recessing tool 47.48 about a pivot axis 49.50 which is arranged in the upper end area of the recessing tool 47.47.48.48 and which extends at right angles to the track direction. A threaded spindle 51 is provided, which threaded spindle 51 is arranged in the track side region of the recessed tool holder 43.

A moving nut 52 is mounted on the threaded spindle 51, which can be rotated, for example, via a chain drive 53.

As shown in FIG. 8, a structural unit consisting of, for example, four twin-leg recess tool units is driven together by a chain drive 53 via two threaded spindles 51. As shown in FIG.

Each recessing tool 47, 47, 48, 48 is connected in its central region to a displacement nut 52, which is connected to a threaded spindle 51 and to a displacement nut 5.
This is a component of a raking drive device consisting of 2 parts.

The two transfer nuts 52 in the pair of recessing tools 47, 47; 48, 48 are provided with opposite threads.

Due to the cooperation of the moving nut 52 and the threaded spindle 51, the recessing tool 47.degree. 47.48.48 is forced into movement, each time with an equal stroke.

This results in a synchronous scraping movement of the recessing tools 47, 48.

Two eccentric arms separated from each other have their respective recess tool pairs 44.45 Both recess tools 47° 47; 4B
, 48 are pivotally mounted, the recess tool 47
and 47, 48, and 48 vibrate in the same phase, and both pairs of recessing tools 44° and 45 vibrate in opposite directions.

This is indicated by the thin small solid or dashed arrows at the top and bottom of FIG.

The working style of the twin spread-leg type deep facing tool unit 42 shown in FIG. 7 is the same as that of the twin spread-leg type deep facing tool unit 1 shown in FIG. 6, except for the synchronous scraping movement. be.

However, in the embodiment shown in FIG.
The ballast volume displaced during the thrusting of the recessing tools 47, 48 into 2 is smaller than in the embodiment of FIG.

This is because the recessing tools 47.47 and 48.4B are placed back to back to each other, and are not curved or offset at right angles to the track. .

The twin spread-leg type deep facing tool unit 42 shown in the figure constitutes a mechanical structural unit with a set of four adjacent to each other in the direction perpendicular to the orbital direction, and this structural unit as a whole is one.
It can be moved up and down by two elevation drive devices 54.

In this embodiment as well, the twin open leg type deep facing tool unit 4
2 can form a mechanical component individually or in pairs on each side of the rail 3 or 4 of the track.

A large number of twin-leg recess tool units based on the various embodiments of the invention described above can be arranged one behind the other in the track direction, as shown by the broken lines in FIG.

Further advantageously, the twin split-leg type deep facing tool unit 42 has the following features:
The trackwise dimension X is less than or equal to twice the average sleeper pitch 2.

In this way, even if a large number of twin-legged recessing tool units are arranged in the track direction, each recessing tool pair can smoothly enter into each section between sleepers, and will not interfere with each other. It is possible to work without any problems.

Furthermore, it is also possible to arrange one component unit on the vehicle body frame immovably in the track direction, and only the second component unit to be movable relative to the vehicle body frame in the track direction.

In FIG. 10, 6. does not correspond to rail 3. The tamping tool of the twin-legged recessed tool unit 7 shown in No. 111ffl is shown in a schematic plan view.

As indicated by the small thin arrows, the individual tamping tools 12 and 13; 14 and 15 vibrate out of phase with respect to each other, and the tamping tools 13 and 15 opposite each other of both tamping tool pairs 16.17 The vibrations of 14 are also in antiphase with each other.

Twin spread type deep facing tool unit 7 of the embodiment shown in FIG.
It is also possible to vibrate the tamping tools of each pair of tamping tools in the same phase and the tamping tools of both pairs of tamping tools to vibrate in opposite phases to each other.

The invention is not limited to the illustrated embodiment.

For example, you can do the following: In other words, the raking, elevation and vibration movements of the tamping tool can be carried out in different mechanical, hydraulic or electrical forms, or in combinations thereof.

Furthermore, it is also possible to use a hydraulic compression drive cylinder to generate the oscillating motion, and to generate the oscillatory motion by applying waves to the pressure medium using a wave generator or the like.

The lower part of the tamping tool with the ice ax plate of the present invention is not limited to the shape shown.
