ORIGINAL TEXT
Ma/Ke The invention relates to a tamping machine for tamping a track, comprising a machine frame supported on on-track undercarriages and a two-sleeper tamping unit with tamping tools which are arranged in series in the longitudinal direction of the machine and are vibratable and squeezable by means of vibration and squeeze drives, with tamping tines for simultaneously tamping two adjacent sleepers, the tamping tools being mounted on a tool carrier which is connected to an auxiliary frame so as to be vertically adjustable.
It is clear from the article "Innovations in tamping machines" in the Railway Technical Review 85/86, 27, pages 51-56 that with regard to tamp;ng mach;nes, there is a difference in principle between machines for track and for point tamping. Point tampin~ machines are only equipped w;th so-called single-sleeper tamping units, suitable for tamping a single sleeper. The tamping tools or tamping tines of such point tamping machines, moreover9 are also mounted ~or pivoting or vertical adjustment in a variety of ways by means of individual drives, to achieve thereby the best possible adaptation of the individual tamping tines to the irregular course of the rails in point sections. In order to tamp the initial region of the diverging rail lengths jointly in conjunction with the tamping of the main track, the point tamping units are furthermore alsv mounted on the machine frame for transverse displacement within a relatively wide range. In this connection see also US 4,537,135 B. MorPover, the track lifting and lining unit for lifting the very heavy point sections is of strengthened con~truction and is provided with special hook-shaped gripping members for abutment against the rails. Tampin~l machines with a two-sleeper tamping unit 3 ~ ~
are used for particularly efficient tamping of point-free track sections and have a lighter track lifting and lining unit compared with point tamping machines.
Already known through GB 2,201,178 A or EP 0 386 398 A1 is a point tamping unit for tamping single sleepers which is composed of four tamping components, arranged side by side in the transverse direction of the machine and transversely displaceable independently of one another by means of drives.
Each of these tamping components has a pair of tamping tools which may be squeezed together by means of squeeze drives ~or jointly tamping a single sleeper. It is thereby possible, with appropriate mutually independent transverse displacement of the individual tamping components, to achieve more satisfactory adaptation to tamping obstructions and thus even more complete point tamping.
With regard to the railway track tamping units provided for high ta~ping performance, a distinction is made between single- and two-sleeper tamping units, a particularly high tamping performance obviously being obtainable with the latter. However, the sleeper spacing must be even for frictionless use of a two-sleeper tamping unit. Tha constructions described in more detail below have already become known for resolving the problem of uneven sleeper spacings.
EP 0 208 826 A1 describes a tamping machine with two two-sleeper tamping units spaced apart from one another in the ~ransverse direction of the machine. Each of these two two-sleeper tamping units is composed of eight tamping tools altogether, pivotably mounted on a common tool carrier and aux;liary frame and each havin~ two tamping tines, tha said tamping tools being connected by way of squeeze drives to a common centrally-disposed vibration drive. The total of eight tamping tools, associated with each auxiliary frame, are arranged in two rows, extending in the longitudinal direction 2~3~
of the machine and arranged side by side in the transverse direction o~ the machine, of four tamping tools forming two pairs respectively. Thus the tamping bearing surfaces, located on either side of a rail, of two sleepers disposed one behind the other can be conso1idated simultaneously, with a very high tamping performance being obtained with a single lowerin~ movement of the two-sleeper tamping unit. To enable, in particular, track sections with sleepers lying obliquely or even double sleepers to be tamped as well, the tamping tines respectively situated at the ends, in relation to the longitudinal direction of the machine, are mounted on the corresponding tamping tool for vertical adjustment by means of individual drives. This enables the appropriate tamping tine to be lifted into an out-of-service position in the event of a tamping obstruction impeding the immersion of a tamping tine and in parallel therewith enables the two-sleeper tamping unit to be freely lowered for tamping.
Two-sleeper tamping units of this kind are exclusively used in point- and crossin~-free track sections. The possibil;ty of point-use, among other things, is certainly indicated in Fig. 8, ~ut an operation of this kind would not produce a satisfactory work result both because of the low transverse displaceability of the unit and the need to centre the total of 32 tamping tines.
Finally, according to US 4,282,815 B, a further two-sleeper tamping unit is known which has single tamping un;ts, each vertically adjustable by means of an in~ividual drive, which are respectively arranged on a common auxiliary frame immediately adjacent to one another in the longitudinal direction of the machine.
The object underlying the invention is to create a tamping machine described in the i-ntroduction which may be used both in plain track and in point sections, achieving a very high tamping performance and accurate track geometry.
2 ~ 9 ~
This object is achieved, according to the invention, in that a total oF four auxiliary frames are provided, transversely displaceable independently o~ one another by means of individual transverse adjustment drives and each forming an individual tamping component, with, respectivelyJ
four tamping tools arranged in series in the longitudinal direction of the machine, an individual tool carrier which is vertically adjustable by means of a vertical adjustment drive and an individual vibration drive being associated with each of the four tamping components.
With this construction, the two-sleeper tamping unit, envisaged since its development in practical application for plain track sections only, can for the first time be used for efficient tamping of point sections as well, overcoming the considerable prejudices prevailing among experts, while unrestrictedly maintaining its high tamping performance. It is of particular advantage here that the fundamental structural concept of the arrangement of the tampir,g tools and their connection to a vibration drive remains unchangedl on the one hand, but on the other hand the allocation of the tamping tools to four auxiliary frames in all which are transversely displaceable independently of one another makes very simple and extensive adaptation of the tamping tines to th~ various tamping obstructions possible. In addition, as a result of the simultaneous tamping of two sleepersl particularly in the assymmetrical long sleeper region, more satisfactory support of the point is ensured and with it the accuracy of the track geometry is improved. It is of additional advantage in this case that the simultaneous tamping of two sleepers also has as a consequence a considerable reduction in the number of track lifting and lining operations and also reduced strain on the rail fastenings which are particularly stressed in the actual point region by the heavy long sleepers. Furthermore, tamping the plain track up to the beginnin3 of a point with a plain track tamping machine and tamping the following point with a point 2 ~
s tamping machine, with the delayed "piecing together" which in most cases is temporally dependent on organizational circumstances, is also avoided in a particularly advantageous manner.
The further development of the tamping machine according to claim 2 or 3 has the advantage, ir. combination with the design of four mutually independent tamping components, of permitting even more extensive adaptation to the irregular course of the rails or to tamping obstructions. Because of the specific mounting of the tamping tines situated at the ends, they can be displaced or li~ted into an out-of-service position in the event of a tamping obstruction, so that the tamping component with the remaining tamping tines can be freely lowered for tamping.
With the further development according to claim 4, it is possible to achieve the particular advantage that with the single pressing of a button, the outer tamping tines may be moved quickly and precisely from a normal working position into an expanded working position, so that in this position they can tamp both the left and the right tamping bearing surface of a rail of a branch track simultaneously. Limiting the pivoting movement results in reduced control required as far as the operator is concerned and is of especial advantage particularly in connectisn with the increased control required for the total of 32 tamping tines of a two-sleeper tamping unit.
The vert;cally adjustable mounting of the outermost tamping tines according to claim 5 enables them to be quickly transferred into an out-of-service position, so that even in those cases in which a tamping obstruction is located exactly underneath an outer tamping tine, the uni~peded operation of the remaining tamping tines is ensured.
The two-part design of the tool carrier according to 2 ~
claim 6 enables only half of the tamping component to be used operationally if appropriate for tamping a single sleeper in particularly difficult point sections, such as in frog areas, for example, while the other half of the tamping component remains in a raised inoperative position.
The advantageous further developments according to cla;ms 7 and 8 enable both the rapid adaptation of the tamping tines to the obliquely-lying long sleepers and the simultaneous tamping of all the tamping bearing surfaces of a long sleeper to take place, as the transverse displacement range of the tamping components is considerably increased.
According to a particularly advantageous further development according to claim 9, the four tamping csmponents can be used with a particularly high tamping performance in conjunction with the continuous advancing of the tamping machine. The tamping machine is thus optimally suitable both for track- and for point-use.
The specific mounting of the two ou-ter tamping components according to claim 10 makes an extended working area possible, more particularly by way of the support by an individual t21escopically extendable support frame, with the result that the rail lengths of the branch track in the long sleeper area can also be tamped in a single working pass at the same time as the main track.
The auxiliary lifting device according to claim 11 is of great advantage, particularly in connection with the complete tamping of a point, in order to achieve permanent track geometry correction. In addition, the removal of stress on the track lifting and linin~ unit and thus the lighter construction thereof is made possible.
With the features according to claims 12 and 13, it is possible to combine the two tamping components, each associated with one rail length, quickly and simply into a single component for working use in plain track sections.
With the particular further development according to claim 14, the vibration drive may be arranged such that the two inner tamping components with their respective tamping tines may be positioned immediately adjacent to one another in order to achieve an enlarged area of use.
Finally, in combination with a lifting hook as the gripping member according to claim 15 for the track lifting and lining unit, the problem-free operational use of the tamping machine in the point region is ensured.
The invention is described in more detail below with the aid of embodiments represented in the drawing, in which Fig. 1 shows a simpl;fied side view of a tamping machine, designed in accordance with the invention, comprising a two-sleeper tamping unit formed ~rom four tamping components which are transversely displaceable independently of one another, Fig. 2 shows a simplifed perspective representation of the two-sleeper tamping unit, Fig. 3 shows a further embodiment of a two-sleeper tamping unit in side view, one of the two tamping tines of a tamping tool in each case being designed for pivoting by means of an individual drive about an axis extending in the longitudinal direction of the machine, Fig. 4 shows a view of a part of the tamping unit according to Fig. 3 tarrow IV) in the longitudinal direction of the machine, Fig. ~ shows a partial side view of a further two-sleeper ~9~379~
tamping unit, in which the respective outer tamping tines, in relation to the longitudinal ~irection of the machine, are mounted for vertical adjust~ent, Fig. 6 shows a further two-sleeper tamping unit in side view, composed of two separate tamping arrangements per tamping component which are arranged in series in the longitudinal direc:tion of the machine and which are vertically adjustable independently of one another, Fi9. 7 shows a further embodiment in a simplified cross-section through a tamping machine with ~our tamping components which are transversely displaceable independently of one another and form a two-sleeper tamping unit7 the transverse guideways of which are mounted on a machine frame also for transverse displacement ;n order to increase the transverse displacement path J and Fig. 8 shows a very simplified, partial side view, in schematic form, of a further embodiment in which the two outer tamping components are secured to a telescopically extendable support frame.
A tamping machine 43J evident in Fig. 1, with a machine frame 45 supported on on-track undercarriages 44 has a central power plant 46 for supplying power and also a motiv~ drive 47.
All four tamping components 3 of a two-sleeper tamping unit 1 are secured to a tool carrier 48 which is connected at one longitudinal end to the track 18 by means of an on-track undercarriage 49 and is supported with its o~posite end on the machine frame 45 so as to be displaceable longitudinally and is connected to a longitudinal displacement drive 50.- Lifting hooks 53 and lifting rollers 54 which are vertically and transversely adjustable by means of drives are provided on each longitudinal side of the machine for a track lifting and 3 ~ 3,~
lining unit 52 which has lif-ting and 1ining drives, is arranged immediately in front of the tamping unit 1 in the working direction (arrow 51) and is connected to the tool frame 48. Furthermore, on each longitudinal side of the machine there is provided an auxiliary lifting device 55, connected to a lifting drive, for picking up a rail length of a branch line running laterally adjacent to the machine 43. A
reference system 56 serves to detèrmine the track geometry errors, a working cab is e~uipped w;th a central control means 57.
In operational use, a tamping rnachine 43 of this kind is continuously mobile with its machine frame 45, while the tool frame 48 together with the four tamping components 3 and the track lifting and lining un;t 52 is moved forwards progressively at intervals of two sleepers.
The two-sleeper tamping unit 1, represented only in part in Fig. 2, is composed of a total oF four tamping components 3, arranged side by side in the transverse direction of the machine and transversely displaceable independently of one another by means of individual transverse adjustment drives 2, of which, for the sake of greater clarity, only one tamping component 3, the outer one in relation to the transverse direction of the machine, has ~een represented in its entirety and the adjacent, inner, tamping component 3 has only been represented partially. Each of these four tamping components 3 in all has four tamping tools 6 to 9, arranged in series in the longitudinal direction of the machine and each connected to squeeze drives 4 and a vibration drive 5. The said tamping tools are mounted on a tool carrier 11 for pivoting in each case about an axis 10 extending perpendicularly to the longitudinal direction of the machine. Each of the total of four tool carriers 11 of the two-sleeper tamping unit 1 is connected by means of an individual vertical adjustment drive 12 to an auxiliary ~rame 14 mounted for transverse displacement on transverse guideways 13. Each of these 2~3~
auxiliary frames ~4 has two vertical guideways 15, extending vertically and parallel to one another, for mounting the respective tool carrier 11. Each of the four tamping tools 6 to 9 of a tamping component 3 is connected to two tamping tines 16 arranged side by side transversely to the longitudinal direction of the machine. The transverse ~uideways 13 are mounted on the tool frame 48 (or in another possible construction, on the machine frame 45) of the tamping machine 43. A lock;ng device 19 is provided for the optional connection of the respective outer auxiliary frame 14, in the transverse direction of the machine, to the adjacent inner auxiliary frame 14. This locking device has a bolt which is connected to a drive 20 and is mounted for displacement from a closing into an open position.
The two-sleeper tamping unit 1 represented in Fig. 2 is situated in the precise position for treating a point section with a main and branch track 21 and 22 respectively. After the opening of the locking device 19, the adjacent tamping components 3 respectively associated with one longitudinal rail side have been moved far enough apart From one another by operation of the two transver~e adjustment drives 2 to enable the tamping tines 16 of the respective tamping tools 6 to 9, notw;thstanding the branch track 22, to be ~reely immersible in the ballast for the simultaneous tamping of two sl~epers 17 arranged one immediately behind the other in the longitud;nal direction of the machine. When maintenance work on the point section has been completed, the two adjacent inner and outer tamping components 3, provided in each case for tamping a rail length, are joined by means of the locking device 19 in practical terms into a combined tamping component again, forming a structural unitJ for efficient tamping of a plain track section.
In the two-sleeper tamping unit 1 evident in Fig. 3 and 4, for the sake of simplicity and greater clarity, components perform;ng the same function are given the same reference numerals as in Fig. 1 and 2, as they are in the subsequent Figures. Of the two tamping tines 16 connected in each case to one tamping tool 6 to 9, those which are further away from the associated auxiliary frame 14 are mounted on the corresponding tamping tool 6 to 9 for pivoting about a respective axis 23 extending in the longitudinal direction of the machine, and are in each case connected to an indlvidual pivot drive 24. Two end stops 25, 26 are provided to limit the pivoting movement of each pivotably mounted tamping tine 16 between two tamping positions. The pivota~le tamp1ng tines 16 are respectively adjustable by means of the said pivot drive 24 from a first working pos;tion (see Fig. 4, r;ght-hand tamping component 3), extending with respect to their longitudinal direction approximately parallel to the tamping tine 16 adjacent to them in the transverse direction of the machine, into a second working position (see left-hand tamping component 3 in Fig. 4), suitable for the immersion of the two tampiny tines 16 on either side of a rail 27. Since these two working positions are respectively defined by the said end stops 25, 26, the adjustment of the tamping tines 16 required for tamping a specific point section can be effected relatively easily and quickly as the operator merely has to choose between two ~ossible positions. Each vibration drive 5 is arranged immediately beneath the tran verse guideways 13 or above an eccentric shaft 28 and is connected by a chain 29 to the eccentric shaft 28 supporting the squee~e drives 4.
As is evident in Fig. 5, the foremost and the rearmost tamping tines 16 (the latter not represented) of each tamping component 3, in the longitudinal direction of the machine or track, are mounted on the corresponding foremost and rearmost tamping tools 6 and 9 respectively, for vertical adjustment independently of one another by means of respective individual drives 58. This enables the tamping component 3 to be lowered into the working position for tamping despite a tamping obstruction (e.g. an obliquely-lyin9 sleeper 173 located exactly under a vertically adjustable tamping tine 16.
3j'l3 ~3 The two-sleeper tamping unit 1 ev;dent in Fig. 6 is similarly composed of four tamping components 3, transversely d;splaceable independently of one another in the transverse direction of the machine or track and of identical design, each of which has two tool carriers :30, 31, arranged in series in the longitudinal direction of the machine and vertically adjustable independently of one another by means of respective individual vertical adjustment drives 12. Each of these two tool carriers 30, 31 is connected to an individual vibration drive 5 and the latter is connected to two squeeze drives 4, and thus forms a tamping arrangement for tamping a single sleeper. The two tool carriers 30, 31 are each mounted for vertical adjustment independently of one another on two vertical guideways 15 extending vertically and parallel to one another, the four vertical guideways 15 altogether being secured to a common auxiliary frame 14. As a result o~ the specific design of this two-sleeper tamping unit 1, the two tamping tool pairs 6, 7 or 8, 9 may be optionally lowered for tamping subject to possible tamping obstructions.
The four tamping components 3 of the two-sleeper tamping unit 1 evident in Fig. 7 are arranged for displacement on transverse guideways 13 and mounted on an intermediate frame 34 for rotation about a vertical axis 33 by means of a dr;ve 32. The said intermediate fram0 is itself connected to an additional frame 35 which is mounted for displacement on further additional 9uideways 37 connected to a machine frame 36, and which is connected to an individual transverse displacement drive 38. This enables the range of transverse displacement of the four tamping components 3 to be substantially increased by the fact that the transverse guideways 13 serving to support the tamping components 3 are similarly displaced transversely in relation to the machine frame 36~ The tamping components 3 may be pivoted about the said axis 33 entirlely independently of this transverse displacement, for adaptation to obli~uely-lying long sleepers in the point region.
2 ~ .S~ ~ ~
According to Fig. 8, the outer tamping components 3, ;n relation to ~he transverse direction of the machine, are each mounted for rotation about a vertical axis 39 on a support frame 40 which is telescopically extendable and is supported on a machine frame 45. The said support frame is mounted with its opposite end to the said axis 39 on the machine frame 45 similarly for rotation about a vertical axis 41 and is connected to a corresponding drive 42. As depicted in Fig. 7, the two inner tamping components 3 are mounted for transverse displacement on an additional frame which is itself connected to the machine frame 45 For ro-tation about a vertical axis.
Thus, in the course of tamping a point, it is also possible to tamp the rail lengths of the diverging track at the same time so that all the bearing surfaces of the long sleepers can be consolidated in a single working pass of the tamping machine.
Ma/Ke The invention relates to a tamping machine for tamping a track, comprising a machine frame supported on on-track undercarriages and a two-sleeper tamping unit with tamping tools which are arranged in series in the longitudinal direction of the machine and are vibratable and squeezable by means of vibration and squeeze drives, with tamping tines for simultaneously tamping two adjacent sleepers, the tamping tools being mounted on a tool carrier which is connected to an auxiliary frame so as to be vertically adjustable.

of the machine and arranged side by side in the transverse direction o~ the machine, of four tamping tools forming two pairs respectively. Thus the tamping bearing surfaces, located on either side of a rail, of two sleepers disposed one behind the other can be conso1idated simultaneously, with a very high tamping performance being obtained with a single lowerin~ movement of the two-sleeper tamping unit. To enable, in particular, track sections with sleepers lying obliquely or even double sleepers to be tamped as well, the tamping tines respectively situated at the ends, in relation to the longitudinal direction of the machine, are mounted on the corresponding tamping tool for vertical adjustment by means of individual drives. This enables the appropriate tamping tine to be lifted into an out-of-service position in the event of a tamping obstruction impeding the immersion of a tamping tine and in parallel therewith enables the two-sleeper tamping unit to be freely lowered for tamping.
Two-sleeper tamping units of this kind are exclusively used in point- and crossin~-free track sections. The possibil;ty of point-use, among other things, is certainly indicated in Fig. 8, ~ut an operation of this kind would not produce a satisfactory work result both because of the low transverse displaceability of the unit and the need to centre the total of 32 tamping tines.
Finally, according to US 4,282,815 B, a further two-sleeper tamping unit is known which has single tamping un;ts, each vertically adjustable by means of an in~ividual drive, which are respectively arranged on a common auxiliary frame immediately adjacent to one another in the longitudinal direction of the machine.
The object underlying the invention is to create a tamping machine described in the i-ntroduction which may be used both in plain track and in point sections, achieving a very high tamping performance and accurate track geometry.
2 ~ 9 ~
This object is achieved, according to the invention, in that a total oF four auxiliary frames are provided, transversely displaceable independently o~ one another by means of individual transverse adjustment drives and each forming an individual tamping component, with, respectivelyJ
four tamping tools arranged in series in the longitudinal direction of the machine, an individual tool carrier which is vertically adjustable by means of a vertical adjustment drive and an individual vibration drive being associated with each of the four tamping components.
With this construction, the two-sleeper tamping unit, envisaged since its development in practical application for plain track sections only, can for the first time be used for efficient tamping of point sections as well, overcoming the considerable prejudices prevailing among experts, while unrestrictedly maintaining its high tamping performance. It is of particular advantage here that the fundamental structural concept of the arrangement of the tampir,g tools and their connection to a vibration drive remains unchangedl on the one hand, but on the other hand the allocation of the tamping tools to four auxiliary frames in all which are transversely displaceable independently of one another makes very simple and extensive adaptation of the tamping tines to th~ various tamping obstructions possible. In addition, as a result of the simultaneous tamping of two sleepersl particularly in the assymmetrical long sleeper region, more satisfactory support of the point is ensured and with it the accuracy of the track geometry is improved. It is of additional advantage in this case that the simultaneous tamping of two sleepers also has as a consequence a considerable reduction in the number of track lifting and lining operations and also reduced strain on the rail fastenings which are particularly stressed in the actual point region by the heavy long sleepers. Furthermore, tamping the plain track up to the beginnin3 of a point with a plain track tamping machine and tamping the following point with a point 2 ~
s tamping machine, with the delayed "piecing together" which in most cases is temporally dependent on organizational circumstances, is also avoided in a particularly advantageous manner.
The further development of the tamping machine according to claim 2 or 3 has the advantage, ir. combination with the design of four mutually independent tamping components, of permitting even more extensive adaptation to the irregular course of the rails or to tamping obstructions. Because of the specific mounting of the tamping tines situated at the ends, they can be displaced or li~ted into an out-of-service position in the event of a tamping obstruction, so that the tamping component with the remaining tamping tines can be freely lowered for tamping.
With the further development according to claim 4, it is possible to achieve the particular advantage that with the single pressing of a button, the outer tamping tines may be moved quickly and precisely from a normal working position into an expanded working position, so that in this position they can tamp both the left and the right tamping bearing surface of a rail of a branch track simultaneously. Limiting the pivoting movement results in reduced control required as far as the operator is concerned and is of especial advantage particularly in connectisn with the increased control required for the total of 32 tamping tines of a two-sleeper tamping unit.
The vert;cally adjustable mounting of the outermost tamping tines according to claim 5 enables them to be quickly transferred into an out-of-service position, so that even in those cases in which a tamping obstruction is located exactly underneath an outer tamping tine, the uni~peded operation of the remaining tamping tines is ensured.
The two-part design of the tool carrier according to 2 ~
claim 6 enables only half of the tamping component to be used operationally if appropriate for tamping a single sleeper in particularly difficult point sections, such as in frog areas, for example, while the other half of the tamping component remains in a raised inoperative position.
The advantageous further developments according to cla;ms 7 and 8 enable both the rapid adaptation of the tamping tines to the obliquely-lying long sleepers and the simultaneous tamping of all the tamping bearing surfaces of a long sleeper to take place, as the transverse displacement range of the tamping components is considerably increased.
According to a particularly advantageous further development according to claim 9, the four tamping csmponents can be used with a particularly high tamping performance in conjunction with the continuous advancing of the tamping machine. The tamping machine is thus optimally suitable both for track- and for point-use.
The specific mounting of the two ou-ter tamping components according to claim 10 makes an extended working area possible, more particularly by way of the support by an individual t21escopically extendable support frame, with the result that the rail lengths of the branch track in the long sleeper area can also be tamped in a single working pass at the same time as the main track.
The auxiliary lifting device according to claim 11 is of great advantage, particularly in connection with the complete tamping of a point, in order to achieve permanent track geometry correction. In addition, the removal of stress on the track lifting and linin~ unit and thus the lighter construction thereof is made possible.
With the features according to claims 12 and 13, it is possible to combine the two tamping components, each associated with one rail length, quickly and simply into a single component for working use in plain track sections.
With the particular further development according to claim 14, the vibration drive may be arranged such that the two inner tamping components with their respective tamping tines may be positioned immediately adjacent to one another in order to achieve an enlarged area of use.
Finally, in combination with a lifting hook as the gripping member according to claim 15 for the track lifting and lining unit, the problem-free operational use of the tamping machine in the point region is ensured.
The invention is described in more detail below with the aid of embodiments represented in the drawing, in which Fig. 1 shows a simpl;fied side view of a tamping machine, designed in accordance with the invention, comprising a two-sleeper tamping unit formed ~rom four tamping components which are transversely displaceable independently of one another, Fig. 2 shows a simplifed perspective representation of the two-sleeper tamping unit, Fig. 3 shows a further embodiment of a two-sleeper tamping unit in side view, one of the two tamping tines of a tamping tool in each case being designed for pivoting by means of an individual drive about an axis extending in the longitudinal direction of the machine, Fig. 4 shows a view of a part of the tamping unit according to Fig. 3 tarrow IV) in the longitudinal direction of the machine, Fig. ~ shows a partial side view of a further two-sleeper ~9~379~

A tamping machine 43J evident in Fig. 1, with a machine frame 45 supported on on-track undercarriages 44 has a central power plant 46 for supplying power and also a motiv~ drive 47.
All four tamping components 3 of a two-sleeper tamping unit 1 are secured to a tool carrier 48 which is connected at one longitudinal end to the track 18 by means of an on-track undercarriage 49 and is supported with its o~posite end on the machine frame 45 so as to be displaceable longitudinally and is connected to a longitudinal displacement drive 50.- Lifting hooks 53 and lifting rollers 54 which are vertically and transversely adjustable by means of drives are provided on each longitudinal side of the machine for a track lifting and 3 ~ 3,~
lining unit 52 which has lif-ting and 1ining drives, is arranged immediately in front of the tamping unit 1 in the working direction (arrow 51) and is connected to the tool frame 48. Furthermore, on each longitudinal side of the machine there is provided an auxiliary lifting device 55, connected to a lifting drive, for picking up a rail length of a branch line running laterally adjacent to the machine 43. A
reference system 56 serves to detèrmine the track geometry errors, a working cab is e~uipped w;th a central control means 57.
In operational use, a tamping rnachine 43 of this kind is continuously mobile with its machine frame 45, while the tool frame 48 together with the four tamping components 3 and the track lifting and lining un;t 52 is moved forwards progressively at intervals of two sleepers.
The two-sleeper tamping unit 1, represented only in part in Fig. 2, is composed of a total oF four tamping components 3, arranged side by side in the transverse direction of the machine and transversely displaceable independently of one another by means of individual transverse adjustment drives 2, of which, for the sake of greater clarity, only one tamping component 3, the outer one in relation to the transverse direction of the machine, has ~een represented in its entirety and the adjacent, inner, tamping component 3 has only been represented partially. Each of these four tamping components 3 in all has four tamping tools 6 to 9, arranged in series in the longitudinal direction of the machine and each connected to squeeze drives 4 and a vibration drive 5. The said tamping tools are mounted on a tool carrier 11 for pivoting in each case about an axis 10 extending perpendicularly to the longitudinal direction of the machine. Each of the total of four tool carriers 11 of the two-sleeper tamping unit 1 is connected by means of an individual vertical adjustment drive 12 to an auxiliary ~rame 14 mounted for transverse displacement on transverse guideways 13. Each of these 2~3~
auxiliary frames ~4 has two vertical guideways 15, extending vertically and parallel to one another, for mounting the respective tool carrier 11. Each of the four tamping tools 6 to 9 of a tamping component 3 is connected to two tamping tines 16 arranged side by side transversely to the longitudinal direction of the machine. The transverse ~uideways 13 are mounted on the tool frame 48 (or in another possible construction, on the machine frame 45) of the tamping machine 43. A lock;ng device 19 is provided for the optional connection of the respective outer auxiliary frame 14, in the transverse direction of the machine, to the adjacent inner auxiliary frame 14. This locking device has a bolt which is connected to a drive 20 and is mounted for displacement from a closing into an open position.
The two-sleeper tamping unit 1 represented in Fig. 2 is situated in the precise position for treating a point section with a main and branch track 21 and 22 respectively. After the opening of the locking device 19, the adjacent tamping components 3 respectively associated with one longitudinal rail side have been moved far enough apart From one another by operation of the two transver~e adjustment drives 2 to enable the tamping tines 16 of the respective tamping tools 6 to 9, notw;thstanding the branch track 22, to be ~reely immersible in the ballast for the simultaneous tamping of two sl~epers 17 arranged one immediately behind the other in the longitud;nal direction of the machine. When maintenance work on the point section has been completed, the two adjacent inner and outer tamping components 3, provided in each case for tamping a rail length, are joined by means of the locking device 19 in practical terms into a combined tamping component again, forming a structural unitJ for efficient tamping of a plain track section.
In the two-sleeper tamping unit 1 evident in Fig. 3 and 4, for the sake of simplicity and greater clarity, components perform;ng the same function are given the same reference numerals as in Fig. 1 and 2, as they are in the subsequent Figures. Of the two tamping tines 16 connected in each case to one tamping tool 6 to 9, those which are further away from the associated auxiliary frame 14 are mounted on the corresponding tamping tool 6 to 9 for pivoting about a respective axis 23 extending in the longitudinal direction of the machine, and are in each case connected to an indlvidual pivot drive 24. Two end stops 25, 26 are provided to limit the pivoting movement of each pivotably mounted tamping tine 16 between two tamping positions. The pivota~le tamp1ng tines 16 are respectively adjustable by means of the said pivot drive 24 from a first working pos;tion (see Fig. 4, r;ght-hand tamping component 3), extending with respect to their longitudinal direction approximately parallel to the tamping tine 16 adjacent to them in the transverse direction of the machine, into a second working position (see left-hand tamping component 3 in Fig. 4), suitable for the immersion of the two tampiny tines 16 on either side of a rail 27. Since these two working positions are respectively defined by the said end stops 25, 26, the adjustment of the tamping tines 16 required for tamping a specific point section can be effected relatively easily and quickly as the operator merely has to choose between two ~ossible positions. Each vibration drive 5 is arranged immediately beneath the tran verse guideways 13 or above an eccentric shaft 28 and is connected by a chain 29 to the eccentric shaft 28 supporting the squee~e drives 4.
As is evident in Fig. 5, the foremost and the rearmost tamping tines 16 (the latter not represented) of each tamping component 3, in the longitudinal direction of the machine or track, are mounted on the corresponding foremost and rearmost tamping tools 6 and 9 respectively, for vertical adjustment independently of one another by means of respective individual drives 58. This enables the tamping component 3 to be lowered into the working position for tamping despite a tamping obstruction (e.g. an obliquely-lyin9 sleeper 173 located exactly under a vertically adjustable tamping tine 16.
3j'l3 ~3 The two-sleeper tamping unit 1 ev;dent in Fig. 6 is similarly composed of four tamping components 3, transversely d;splaceable independently of one another in the transverse direction of the machine or track and of identical design, each of which has two tool carriers :30, 31, arranged in series in the longitudinal direction of the machine and vertically adjustable independently of one another by means of respective individual vertical adjustment drives 12. Each of these two tool carriers 30, 31 is connected to an individual vibration drive 5 and the latter is connected to two squeeze drives 4, and thus forms a tamping arrangement for tamping a single sleeper. The two tool carriers 30, 31 are each mounted for vertical adjustment independently of one another on two vertical guideways 15 extending vertically and parallel to one another, the four vertical guideways 15 altogether being secured to a common auxiliary frame 14. As a result o~ the specific design of this two-sleeper tamping unit 1, the two tamping tool pairs 6, 7 or 8, 9 may be optionally lowered for tamping subject to possible tamping obstructions.
The four tamping components 3 of the two-sleeper tamping unit 1 evident in Fig. 7 are arranged for displacement on transverse guideways 13 and mounted on an intermediate frame 34 for rotation about a vertical axis 33 by means of a dr;ve 32. The said intermediate fram0 is itself connected to an additional frame 35 which is mounted for displacement on further additional 9uideways 37 connected to a machine frame 36, and which is connected to an individual transverse displacement drive 38. This enables the range of transverse displacement of the four tamping components 3 to be substantially increased by the fact that the transverse guideways 13 serving to support the tamping components 3 are similarly displaced transversely in relation to the machine frame 36~ The tamping components 3 may be pivoted about the said axis 33 entirlely independently of this transverse displacement, for adaptation to obli~uely-lying long sleepers in the point region.
2 ~ .S~ ~ ~
According to Fig. 8, the outer tamping components 3, ;n relation to ~he transverse direction of the machine, are each mounted for rotation about a vertical axis 39 on a support frame 40 which is telescopically extendable and is supported on a machine frame 45. The said support frame is mounted with its opposite end to the said axis 39 on the machine frame 45 similarly for rotation about a vertical axis 41 and is connected to a corresponding drive 42. As depicted in Fig. 7, the two inner tamping components 3 are mounted for transverse displacement on an additional frame which is itself connected to the machine frame 45 For ro-tation about a vertical axis.
Thus, in the course of tamping a point, it is also possible to tamp the rail lengths of the diverging track at the same time so that all the bearing surfaces of the long sleepers can be consolidated in a single working pass of the tamping machine.
