Description

Description: TECHNICAL FIELD The present invention relates to a machine frame supported by an undercarriage and a tool frame supported for pivoting about a vertical axis transversely parallel to the raceway. Further comprising a compaction device arranged adjacent to each other transversely of the track, designed to be displaced transversely and vertically independently of each other under the action of a driving force, and The invention relates to a self-propelled track compaction machine including a pair of compactors including a compaction fork designed to be compressed and vibrated by a crusher and designed to pierce in gravel.

BACKGROUND OF THE INVENTION One previously known self-propelled track compaction machine using the above features (US Pat. No. 3,53,531 of the applicant or patentee).
No. 4,687) are arranged on a tool frame which is mounted so as to freely pivot laterally and overhang in the working direction, each of which is arranged one behind the other in the longitudinal direction of the track. And two compensator carriers for supporting the two compactors together with a compensator for compacting two adjacent crossties simultaneously. Each compaction device is a paired compaction tool including compaction forks designed to be displaced and compressed together vertically and to pierce into the left and right gravel of one or the other rail. Contains. The two carriers are displaced transversely independently of each other under the action of a driving force on a tool frame designed to pivot laterally around a vertical axis with respect to the machine frame. It is supported by. This known track compaction machine having a compact structure, typical of older machines in which the compaction device is arranged to overhang on the machine frame, is also independent of each other, in particular in connection with a reference system. It is designed to function as a leveling and compacting machine for compaction such as a switcher with individual compactors designed to move.

In another known compaction machine of the old compact type (see GB 1,213,381), the compaction device is provided with an overhang on a tool frame designed to pivot laterally with respect to the machine frame. Two advantageously vertically displaceable compacting devices, each associated with a rail, are arranged for transverse displacement independently of one another. The compaction device is provided in a transverse displacement path on a long-shaped tool frame designed to overhang the lower device at the head of the machine and to pivot laterally about the vertical axis with respect to the machine frame. It is supported for vertical and transverse displacement, so that the compactor can better accommodate the varying spacing between the rails in the switch. Such a structure is complicated because the laterally pivoting tool frame extends over the rear machine frame and is now fixed to the machine frame via sliding bearings for pivoting movement. Becomes Further, such spaced arrangements may not allow the compaction tool to be positioned parallel to the inclined crossties due to such inaccurate adaptation, resulting in accurate and durable compaction operations. The disadvantage is that it becomes impossible.

Another known self-propelled track compaction machine (see U.S. Pat. No. 4,625,651 of the applicant or patentee) takes the form of a so-called compact type compaction, leveling and aligning machine. These machines show that, in addition to the arrangement of compaction devices and track lifting and alignment devices between the lower devices which are widely spaced from one another, a significantly more accurate correction of the vertical and lateral position of the track is obtained. Has been particularly successful over the past two decades compared to the overhanging machines described above, because the placement of lower equipment at relatively large distances from each other results in a gradual curvature of the rails and avoids excessive flexural stress. . In such a known compaction machine, a separate tool frame with compaction, lifting and alignment devices pivotally connected to the tool frame at one end by a variable length coupling mechanism is provided for each rail. And each laterally pivoting tool frame has at its other end, opposite the coupling, a single supporting and guiding lower part in the form of a free steering lowering device designed to run on rails. Includes equipment. The compacting, lifting and aligning device comprises a so-called laterally pivoting compacting device, a scissor-type lifting device, and a flanged alignment roller for working in a track switch or the like. It takes the form of a switching device.

SUMMARY OF THE INVENTION The problems addressed by the present invention are, in particular, the difficult parts of the orbit,
For example, switchers, or piers laid diagonally or often on gravel floors with different sleeper spacings, can be used quickly and easily even on tracks where the compaction device cannot be adapted accurately. A self-propelled track compaction machine of the type described in

According to the invention, this problem is solved in a self-propelled track compaction machine of the type mentioned at the outset, in which, under the action of the respective drive, the side faces around the vertical axis independently of one another. Tool frames designed to pivot toward one another, provided on the machine frame for independent transverse displacement and mounting of two compaction devices provided with their respective vertical displacement drives .

The solution according to the invention is able to withstand the relatively large working forces which occur in particular in difficult and heavy track constructions and, together with various known compaction devices, even in switchgears or even in normal tracks. It opens up a surprisingly simple and more robust new basic structure that opens up many other design paths to certain design variations. Therefore, by mounting the compaction device according to the invention on two tool frames designed to pivot independently of one another and laterally parallel to the raceway, a particularly rigid design is very simple in design. Which is very large that occurs during compaction,
It also effectively withstands, inter alia, impact-like forces and is not capable of independent individual transverse displacement under the power of each drive,
It very easily results in a quick individual precise pivoting of each compaction device for centering away from the main track, for example on a switch blade. However, in addition to such a very effective use in difficult track sections, especially in switchgears, the compaction device combined with the pivoting tool frame can also be used without restrictions in the normal track, As a result, relatively long track sections, including both normal tracks and switchers, can be compacted more economically and continuously with substantially the same compaction quality. In this regard, the compaction forks are also relatively easily present in the switcher section, while the compaction devices, together with the pivoting tool frame, pivot about their vertical axis for centering. It is particularly advantageous to be able to accommodate oblique positions of long sleepers.

In an advantageous embodiment of the invention, two compaction devices with a pair of compactors for compacting the right and left crossties of one or the other rail are provided at the ends of their pivoting tool frames. The pivoting tool frames, which are mounted on the parts and are elongate, are each further supported by a horizontally extending sliding guide of the machine frame in the area adjacent to the compaction device. The arrangement of the compaction device at the end of the pivoting tool frame is such that the extent to which the compaction device can be displaced laterally is kept out of contact with other structural components and the two pivoting devices Identification that the operator located at the opposite free end has a clear, substantially unobstructed view of the compaction device, which is connected only at one end to the tool frame, which ensures better and more accurate work Has the advantage of In addition, the elongated pivoting tool frame also provides a wide overhanging arrangement of the compaction device for a relatively large total displacement range, so that, for example, a branch track in a switcher section which is joined to the main track by long sleepers. Can be compacted and corrected together with the main trajectory better than before, resulting in a more durable and more accurate position correction. The sliding guides ensure a uniform and safe support of the compaction device at any position on the machine frame.

One particularly advantageous embodiment of the invention is a vertical axis, in which two elongated pivoting tool frames projecting freely in the working direction of the lower device, immediately before, respectively, extend substantially on one or the other rail. Around one of the rails on one or the other rail with the compacting device. Such a special configuration of the two pivoting tool frames allows these tool frames to be effectively supported by the lower device after the compaction device, free and unhindered lateral pivoting movements And the free overhang provides a configuration that will never interfere with the function of the compactor. In addition to the rigid and unobstructed fixing of the two tool frames without mutual interference, the pivoting about the axis substantially above the rails provides an advantageous center displacement which can be adapted especially for a particular rail. It offers a simple adaptability to facilitate the centering of the compaction device to the extent, i.e. the position of slightly different diagonal crossties in the switcher section.

In another embodiment of the present invention, each of the two pivoting tool frames retracted or angularly spaced from at least the longitudinal axis of the machine has at least about 4 pins from its vertical axis to its compaction device. It is preferably designed for a total pivot range of a particular end of the pivoting tool frame having a length of about 5 to 5 meters or about 2 to 3.5 times the track gauge. The length of this pivoting tool frame, in conjunction with the proper retraction, provides a very desirable and sufficiently large total pivoting range for each compaction device to accommodate the diagonal position of the crossties in the switcher section. In addition, this length is the specific displacement and pivoting of each tool frame relative to the characteristics of the track so as to produce a substantially automatic adaptation of the compaction device in the pivoting phase to the oblique ties in the switcher section. This results in an advantageous maximum adaptation of the operating angle range, so that, for example, a switch section of the type in question can be compacted and thus fixed in a much more precise position over the entire length of the long sleeper in a single compaction operation can do.

In another advantageous embodiment of the invention, the vertical axis of each pivoting tool frame is, in the working direction, behind the intermediate axis of the lower device immediately after the compaction device and preferably of the bogie machine frame. It is located behind the central lower device of the form. Despite allowing very large forces to occur during compaction and compensation operations, a compaction machine so constructed has two cabs suitably arranged on lower devices in front of and behind the compaction machine. It also provides both a safe support via a central bogie and an unobstructed placement of two preferably tool frames on the machine frame.

Another advantageous embodiment of the invention provides that the two compacting devices with vertically displaceable drives each rotate around another vertical axis under the power of the drives. Preferably, it is attached to the end of a freely protruding pivoting tool frame so as to rotate toward the axis of the track with respect to the entire lateral pivoting range of the compaction device of about 2.0 m. Features. This arrangement preferably has the advantage of a precise alignment of the compaction fork, which can be carried out at any time quickly and independently of the transverse displacement to a position parallel to the longitudinal axis of the crossties located at an angle. Combines a simple and firm lateral pivoting of the compaction device so as to produce independent transverse displacements. Such alignment can be achieved by the pivotal movement of each compaction device on another vertical axis independently under the power of the respective drive. In this way, using a compaction device which is designed to be displaced independently and very independently around the two pivot axes and which is simply and firmly connected to the machine frame, For the first time it is possible to compact switchgears that are particularly difficult due to the numerous track obstacles associated with the ties.
Due to the total displacement range of the compaction device of about 2.0 m, a relatively simple compaction operation without problems even in the outer switch area, which is still interconnected by long sleepers, is achieved by means of the pivoting tool frame, which extends freely. It becomes possible.

In another particularly advantageous embodiment of the invention, the two long-shaped pivoting tool frames are each composed of several parts and are designed to be nested in the longitudinal direction of the frame, and The compaction device mounted at the end of the frame is coupled to its own drive to produce a longitudinal displacement. Without affecting the advantages already mentioned, such an advantageous simple nesting of the pivoting tool frame allows a quick and precise adaptation of the two compaction devices, i.e. an independent longitudinal displacement. And to enable these devices to be precisely centered on the possibly existing obliquely positioned sleepers to be compacted.

In another advantageous embodiment of the invention, each of the two long-shaped pivoting tool frames is preferably designed to be nested in the longitudinal direction of the frame whose section extends vertically. And a girder including a hydraulically actuated drive disposed at the upper end. Such a simple and rigid construction with a hydraulically actuated drive at the upper end of the girder ensures independent, unhindered adjustment or longitudinal displacement of the compaction device in any position.

In another advantageous practical embodiment of the invention, the two pivoting tool frames having a vertical axis, a displacement drive and a displacement range are plane-symmetric with respect to the longitudinal axis of the machine. Placed in a relationship. This results in a substantially symmetric load distribution between or above the two pivoting tool frames while simultaneously avoiding mutual interference.

In one embodiment which is particularly advantageous in the practical application of the machine according to the invention, it is designed in each case to pivot parallel to the track surface and laterally, in particular to pierce into the left and right gravel of the rail. Preferably, all the compactors of the two compacting devices, including the two pairs of compactors, have their associated compaction forks under the power of the respective hydraulically actuated drive in the longitudinal axis of the track. It is configured in a known manner so as to pivot independently laterally to one another around an axis extending parallel to the core. Such lateral pivoting design of the compaction fork is correspondingly lifted or laterally lifted, especially in connection with the advantages made possible by the pivoting tool frame and the possibility of adjusting the compaction device. Guide rails, which are placed on obstacles which are pivoted on the guide rails, which lead to a further improved avoidance movement or descent of the compaction device, even near track obstacles in the form of switch blades .

Another particularly preferred and advantageous embodiment of the invention is that the pivoting or parallel to the lateral and raceway planes with their respective pivoting tool frames are provided to constitute a compact track compaction, leveling or alignment machine. 2 designed to rotate
The compaction device of the platform is located immediately after in the working direction of the track lifting and positioning device designed to be used in the switch provided on the machine frame, together with the track lifting and positioning device, It is characterized in that it is arranged between two lower devices, in particular in the form of bogies, arranged far apart from one another. The combination of the pivoting tool frame according to the invention with such a compact machine provides a high-quality, relatively fast compaction, for example, even in difficult switch sections, by accurate correction of the vertical and lateral position of the track. The spacing of the lower devices, which are relatively far from each other, ensures a gentle curvature of the rails, in particular to avoid excessive bending stresses in the switch.

Finally, in another advantageous and preferred embodiment of the invention, in the working direction preceding the working direction of the track lifting and alignment device in the working direction, the application as required in a left-hand or right-hand branching track, i.e. The lifting assembly designed for lateral pivoting of the two compactors mounted on their respective pivoting tool frames designed to pivot laterally independently of each other Associated with the device. With such an additional lifting assembly preceding the two pivoting tool frames, the rapidity of the trajectory, even in a branch trajectory placed outside the range of the machine and still joined to the main track by long sleepers, is improved. The compacting device, which is pivoted laterally by a corresponding pivoting tool frame for precise compaction or position correction, can be particularly advantageously lifted to the correct position, so that the type of problem A switchgear can be compacted very economically, relatively easily and with the same operation and with high precision.
