Abstract

A ballast tamping tool assembly comprises two tamping tool carriers arranged successively in a longitudinal direction, a pair of tamping picks mounted on each tamping tool carrier, one of the tamping picks of each pair being arranged at a respective end of the assembly in the longitudinal direction for immersion in a respective one of the cribs, another one of the tamping picks of each pair being one of twin tamping picks, the twin tamping picks being arranged for immersion in cribs adjacent the respective cribs for tamping ballast underneath two adjacent ties, and a third tamping tool carrier arranged between the two successively arranged tamping tool carriers, further twin tamping picks mounted on the third tamping tool carrier, the further twin tamping picks being arranged for immersion in a center crib. Each tamping pick is pivotal about a horizontal axis extending transversely to the track, the horizontal axes extending parallel to each other and the longitudinal direction extending perpendicularly to the horizontal axes. Reciprocating drives pivot the tamping picks, and drives for vibrating the tamping picks connect a respective one of the reciprocating drives to a drive for vibrating the tamping picks. The tamping tool carriers are vertically adjustable independently of each other.

Description

The invention relates to a Stopfaggregat for Unterstopfen thresholds a track, with parallel to each other, horizontal pivot axes pivotable and in relation to this in the transverse direction in pairs arranged stuffed goose, which refers to two with respect to a normal to arranged the pivot axes extending longitudinal direction one behind the other and by drives independently adjustable height Stopfwerkzeugträgern stored and in each case via auxiliary drives with vibration drives are connected, with respect to each stuffing tool carrier said longitudinal direction end-side pair of stuffing tongs for dipping in one end sleeper compartment and two for immersion in one the sleeper compartment adjacent the end sleeper compartment and for stuffing two adjacent sleepers, with regard to the Longitudinally with their pivot axes distanced pairs are stored by twin darts.

Such a tamping unit is already known from US 5,133,263. The Both stuffing tool carriers are on one with a track-traversable machine attached support frame attached and individually or together in the ballast ballast of the track can be lowered. The simultaneous use of both Tool holder is used to edit a three adjacent Thresholds comprehensive track area in a single operation, with each an end-side tamping pick and one of the arranged on the same tool carrier Twin Pimples together the first or the third threshold to support the trio. The two other twin tamping pimples two tool carriers cooperate or are pivoted to each other, to stuff the middle threshold. In addition, it is possible if needed (e.g., with irregular threshold spacing or with track obstacles) only one of the stuffing tool carrier to apply and thus the machine as Einschwellenstopfmaschine use.

In DE-OS 24 26 841 is also a tamping unit with two three Darning tamping tamping tool carriers disclosed either can be lowered together to plug three thresholds or individually can be used.

JP 54-45011 describes an arrangement of three stuffing tool carriers, arranged in track longitudinal direction one behind the other and in their distance are adjustable to each other. Each of the stuffing tool carriers can be lowered individually and with darning picks to stuff a single sill which makes it possible to have one, two or even three thresholds to process per operation.

From US 4,094,250 a tamping machine is known, the two in the machine longitudinal direction arranged one behind the other and independently of each other having height adjustable stuffing tool carrier. On every carrier are Two pairs of twin darts mounted for immersion in two adjacent threshold intermediate compartments are provided and based on Beistellantrieben be spread apart. When lowering together Both stuffing tool carrier, it is possible, three side by side lying thresholds and at the same time the two to the Three groups of adjacent thresholds each half, i. from only one side here to stuff.

Finally, AT 303 793 shows the underfilling of four adjacent ones Thresholds of a track, but without the tamping aggregate in any way to explain in detail.

It is now the object of the present invention, a tamping unit of mentioned type with increased performance and extended applications to accomplish.

This object is achieved with a generic Stopfaggregat thereby that between the two stuffing tool carriers another, by its own drive independent of these height-adjustable, centered Stopfwerkzeugträger is arranged on the two for immersion in a provided with respect to said longitudinal direction central sleeper compartment and for simultaneously plugging two adjacent thresholds from each other settable pairs of twin darts are positioned.

With such a tamping unit is a significant increase the efficiency and stuffing capacity of the machine achievable because at simultaneous use of all three stuffing tool carriers now four sleepers can be supported once. Compared to the conventional machine this means a performance increase of about one third. Consequently Affects such a quadruple constipation also beneficial to the uniform or consistent quality of the work result, which at a block of four simultaneously processed sleepers more reliable and is better to ensure. In addition to this increased efficiency arises from the inventive training but also an extended Variety of uses in terms of number of in one Passage-workable sleepers. This can now be between one, two or four thresholds vary and may vary depending on the prevailing one Circumstances, the threshold distance or the presence of obstacles, be selected or adjusted as needed. Should it be desired can also be an only every second threshold comprehensive stuffing pattern or only the two end thresholds of a group of four to be edited.

Further advantages according to the invention will become apparent from the dependent claims and from the drawing.

The invention is described below with reference to an illustrated in the drawing Embodiment explained in more detail.

Show it:

Fig. 1 is a side view of an inventively designed Stopfaggregates, and

FIGS. 2 to 4 each show a greatly simplified side view of the tamping unit in various operating positions.

An apparent in Fig. 1 Stopfaggregat 1 for Unterstopfen thresholds 2 of a track 3 is a support frame 4 with a - not shown - Tamping machine connected to rails 5 of the track 3 in a through an arrow 6 indicated longitudinal direction is movable. Everybody is here Rail 5 assigned its own tamping unit 1, of which simplicity only one is shown.

The Stopfaggregat 1 has a in the longitudinal direction above on the rail 5 extending unit frame 7, on the whole three stuffing tool carriers 8, 9 and 10 with respect to the longitudinal direction one behind the other are arranged. Each stuffing tool carrier 8-10 is respectively based on of two longitudinally spaced vertical guide columns 11 height adjustable connected to the unit frame 7 and with its own drive 12 for independent vertical adjustment fitted. Furthermore, at each Stopfwerkzeugträger 8-10 as a Eccentric shaft trained vibration drive 13 is provided, respectively Be connected via auxiliary drives 14 with the upper ends of Stopfwerkzeugen 15 is. These are parallel to each stuffing tool carrier 8-10 to each other or perpendicular to the longitudinal direction, horizontal Swivel axes 16 pivotally mounted and in its lower end each with respect to the pivot axis 16, i. in the transverse direction of the track, arranged in pairs and described in more detail below Tuftpickeln fitted.

On each of the two longitudinally positioned with respect to the longitudinal direction Stuffing tool carrier 8 and 10 is an end-side pair of stuffing tugs 17th stored, which provided for immersion in an end-side sleeper compartment 20 is, as well as two pairs of twin potbelts 18, for immersion in a sleeper compartment adjacent to said end sleeper compartment 20 21 are provided. The Twin Stopfpickel 18 are doing with the their associated pivot axes 16 are spaced apart in the longitudinal direction arranged and for Unterstopfen two adjacent thresholds 2 formed from each other beistellbar. Unlike the two mentioned Tool holders 8 and 10 is the third, centrally positioned between them Tool carrier 9 with only two pairs of twin pegs 19 provided for immersion in a central threshold compartment 22 are provided and to Unterstopfen two adjacent thresholds 2 based their Beistellantriebe 14 are formed from each other beistellbar. The Pivot axes 16 of these two pairs of twin pegs 19 are also distanced from each other with respect to the longitudinal direction.

The tamping unit 1 is - with respect to a through the central stuffing tool carrier 9 guided, perpendicular to the longitudinal direction, vertical Symmetrieebene 23 - with all stuffed picks, drives etc., so in all significant details, mirror-symmetrical design.

In the example shown in Fig. 2 of a labor input of Stopfaggregates 1 is only the one end stuffing tool carrier 8 based on the Drive 12 lowered while the other two stuffing tool carrier. 9 and 10 - because of a (not shown) obstacle - in their Remain inoperative. In this situation, only a single one Threshold 2 (shown hatched), with one pair of Twin Stall Picks 18 (in the drawing on the right) of the Stopfwerkzeugträgers 8 is not acted upon for pivoting, but in a vertical position remains until the stuffing tool carrier 8 again from the ballast bed is pulled up. If the obstacle only in the area of the central Stofwerkzeugträgers 9 is, it would be possible, the other end-side Lower stuffing tool carrier 10 and plug a second sill 2 - See dot-dash line shown position of the tamping pick.

Fig. 3 shows the configuration of the tamping pick when tamping two adjacent ones Thresholds 2 on the basis of the simultaneously lowered stuffing tool carriers 8 and 9. The central stuffing tool carrier 9 remains a pair of twin tamping pawls 19 out of service or is not acted upon, while the third stuffing tool carrier 10 entirely in his raised resting position remains.

4, the full deployment of the tamping unit 1 is finally shown, in which all three stuffing tool carriers 8, 9 and 10 are lowered and all Stopfpickel 17, 18 and 19 based on their Beistellantriebe 14 to their Swivel axes 16 pivoted or be provided to four adjacent Thresholds 2 of the track 3 to simultaneously stop.
