Description
~ ~15S~79 ORIGINAL TEXT
Ma/Wi/dob The invention relates to a tamping unit for track tamping machines for tamping two immediately adjacent sleepers of a track, comprising at least two pairs, mounted one followinq the other in the longitudinal direction of the machine on a vertically adjustable tool carrier, of outer and inner tamping tools respectively connected to an eccentric shaft by way of a squeeze drive and having tamping tines for penetration into the ballast, one of the outer tamping tools arranged on either side of the inner tamping tools - with respect to the longitudinal direction of the machine - being designed so as to be independently vertically adjustable relative to the other tamping tools by means of a separate vertical adjustment drive.
A tamping unit of this kind for tamping two immediately adjacent sleepers is described by AT 384 447 B. This tamping unit is equipped with a central vibration drive which is connected by way of squeeze drives to the inner tamping tools and the two outer tamping tools. Each of the two outer tamping tools is flexibly connected to the tool carrier by a lever arrangement in the nature of a parallelogram and is vertically adjustable with the aid of a vertical adjustment drive located between the levers in a vertical plane extending parallel to the longitudinal direction of the machine. This vertical adjustment may be performed independently of the vertical adjustment of the common tool carrier.
A tamping unit for tamping two immediately adjacent sleepers is similarly known from EP 0 208 826 B1, in which each tamping tool is connected by means of a separate squeeze drive to an eccentric shaft provided centrally on the common .. . ..
~ 1 5 ~ 4 7 9 tool carrier. One of the outer tamping tools has a specially designed tamping tine which is vertically adjustable in a vertical guide connected to the tamping tool by means of a separate drive independently of the other tamping tools or of the tool carrier.
According to EP O 314 933 A1, tamping two adjacent sleepers by means of two single sleeper tamping units arranged one immediately following the other in the longitudinal direction of the machine is also known. These single sleeper tamping units are designed so that each is vertically adjustable independently of the other and in operation may also be optionally lowered independently of the other - in order to tamp only a single sleeper.
Furthermore, tamping units for tamping three immediately adjacent sleepers are also known through US 5,133,263 or CH
569 836, these having three pairs of tamping tools on each longitudinal side of the rail. These are mounted in equal allocation - i.e. three tamping tools in each case - on two tool carriers arranged one following the other in the longitudinal direction of the machine, each of the two tamping tools forming the middle tamping tool pair being respectively allocated to one of the tool carriers. The middle sleeper can only be tamped completely when both tool carriers are lowered at the same time.
The object of the present invention is now to provide a tamping unit of the type previously defined with an improved loading capacity of the independently vertically adjustable outer tamping tool.
This object is achieved with a tamping unit of the type previously defined by the fact that the independently vertically adjustable outer tamping tool is mounted on a separate, second tool carrier and is connected by way of the squeeze drive to a separate eccentric shaft, the tool carrier , 3 ~ 4 ~ ~
being mounted for vertical adjustment on a vertical guide and being connected for the vertical adjustment to the separate vertical adjustment drive.
With these features the vertically adjustable outer tamping tool virtually becomes an independent tamping unit in which any adjustment mechanism between tool carrier or tamping tool and tamping tine, which would weaken the structural strength, is dispensed with. Thus, without reducing the considerable mechanical loading capacity of the tamping tools in the slightest, particularly for the rapid penetration thereof into the bedding ballast, a virtually delay-free change-over in order to tamp either one or alternatively two sleepers is possible merely by influencing the operation of the two vertical adjustment drives. Since the tamping tool can now be designed and mounted in the conventional manner with considerable stability, any weakening of an adjustment mechanism known from the prior art which is caused by the permanent vibration effects also does not arise.
Accordingly, in one aspect the present invention resides in a tamping tool assembly for tamping ballast underneath no more than two successive ties of a railroad track, which comprises, two pairs of tamping tools succeeding each other in the direction of elongation of the railroad track, two proximal tamping tools of the pairs being adjacent each other and two distal tamping tools of the pairs being remote from each other and arranged at respective ends of the assembly in said direction, a first vertically adjustable tamping tool carrier, a first crank shaft mounted on the first tamping tool carrier, 3a ~ ~ ~ 5 4 7 ~
drive means connecting the two adjacent proximal tamping tools and one of the distal tamping tools to the first crank shaft for reciprocating the two adjacent proximal tamping tools and the one distal tamping tool in the direction of elongation of the railroad track, a first drive for vertically adjusting the first tamping tool carrier for immersing the two adjacent proximal tamping tools in the ballast between the two successive ties and the one distal tamping tool in the ballast adjacent one of the ties, a second vertically adjustable tamping tool carrier having an end face facing an end face of the first tamping tool carrier, a second crank shaft mounted on the second tamping tool carrier, drive means connecting the other distal tamping tool to the second crank shaft for reciprocating the other distal tamping tool in the direction of elongation of the railroad track, a vertical guide whereon the second tamping tool carrier is mounted for vertical adjustment, and a second drive for vertically adjusting the second tamping tool carrier independently of the first tamping tool carrier for immersing the other distal tamping tool in the ballast adjacent the other one of the successive ties.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is explained in more detail in the following with the aid of the drawing, in which Fig. 1 shows a simplified side view of a tamping machine comprising a tamping unit for tamping two immediately adjacent sleepers, and 4 7 ~
Fig. 2 shows an enlarged detailed view of the tamping unit.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The tamping machine 1 is designed to travel continuously during operation has a machine frame 3 supported on on-track undercarriages 2 and a satellite frame 4 which is displaceable longitudinally relative to the machine frame 3. This .. . .
~l~a~79 . .
satellite frame serves to support a tamping unit 7, designed to tamp two immediately adjacent sleepers 5 of a track 6, and a track lifting-lining unit 8. The various drives are controlled by means of a central control unit 9.
As is shown in Fig. 2, the tamping unit 7 has on either longitudinal side of the rail two immediately adjacent inner tamping tools 10,11 and two outer tamping tools 12,13 arranged on either side thereof - in the longitudinal direction of the machine or track. Whilst the two inner tamping tools 10,11 and one outer tamping tool 12 are mounted on a common, first tool carrier 14, the other outer tamping tool 13 is mounted on a second tool carrier 15. The second tool carrier 15 has a vibration drive 16 with an eccentric shaft 17, on which a squeeze drive 18 connected to the outer tamping tool 13 is rotatably mounted. The second tool carrier 15 is mounted for displacement on a vertical guide 19 and is vertically adjustable by means of a vertical adjustment drive 20. The outer tamping tool 13 mounted on the tool carrier 15 so as to tilt about an axis 21 extending perpendicularly to the longitudinal direction of the machine and horizontally is connected in its lower end region to a tamping tine 22. The eccentric shaft 17 of the vibration drive 16 is arranged on the side of the second tool carrier 15 away from the first tool carrier 14. The guide 19 is located between the axis 21 of the outer tamping tool 13 and the eccentric shaft 17, with respect to the longitudinal direction of the machine. The guide 19 of the second tool carrier 15, which is rectangular in cross-section, and other guides 23 for the vertical adjustment of the first tool carrier 14 are mounted on a common auxiliary frame 24 which is connected to the satellite frame 4 shown in Fig. 1.
The inner tamping tools 10,11 and one outer tamping tool 12 which also have tamping tines 22 and are mounted on the first tool carrier 14 are connected by way of squeeze drives 25 to an eccentric shaft 26 of another vibration drive 27.
... . .. ...
-~IS~i~79 The inner tamping tools 10,11 with their squeeze drives 25 are in this case arranged symmetrically in relation to a vertical plane of symmetry 29 leading through the axis of rotation 28 of the associated eccentric shaft 26. The fir~t tool carrier 14 is vertically adjustable with the aid of a vertical adjustment drive 30. The two vertical adjustment drives 20 and 30 may be coupled for joint or synchronous operation with the aid of the control unit 9.
If both vertical adjustment drives 20 and 30 are operated synchronously, the two tool carriers 14,15 are then lowered simultaneously and all the tamping tines 22 are thereby immersed simultaneously in order to tamp two adjacent sleepers 5 at the same time. Similarly, the lifting of the inner and outer tamping tools 10 to 13 is performed by synchronous operation of the two vertical adjustment drives 20,30. As soon as any obstruction appears in the region of the outer tamping tool 13 which makes penetration of the associated tamping tine 22 into the bedding ballast impossible, only the vertical adjustment drive 30 is operated to lower the first tool carrier 14, causing only the two tamping tines 22 of the inner tamping tools 10,11 and the tamping tine 22 of one outer tamping tool 12 to penetrate into the bedding ballast so as to tamp it. It is advantageous if the independently vertically adjustable outer tamping tool 13 is arranged so as to precede the other tamping tools 10,11,12 in the working direction of the tamping machine 1.
