Facility for renewing tracks

109834/0184

The present invention relates to an improvement in bin directions for renewing tracks, that is, on machines that are used for replacement • old rails and old sleepers with new rails and sleepers. - find manure. In French patent specification no. 1 3o3 5o2 there is one Establishment described in more detail, the task being the new rails to put them down outside the rails to be replaced, to loosen the old rails from the sleepers, to lift these rails and to move them outwards, in such a way that that they can be removed over the new rails that are available. Afterwards, the old sleepers are removed and put on a waiting one Loading the train. Finally, the new sleepers are laid and the new ones that are ready Rails against each other on the predetermined distance with respect to fe pushed each other and attached to the new sleepers. In addition, between the " Depositing device for the old sleepers and the insertion device for the new ones Sleepers provided another device for adjusting the track bedding be.

The main disadvantage of this renewal train is the training of the replacement car. This carriage, on which the most important devices for carrying out the above-mentioned work are provided, essentially consists from a long beam, which with both ends on two Ilormalspur-Eolischemel is supported, with one roller stool on the old and the other is arranged on the new track. In the curves, the longitudinal axis corresponds to this The bowstring beam between the two roller stools. To avoid that at the forward movement of the train the device attached to the said beam These lines do not describe a path with a radius that is smaller than that of the track, in other words that it is not carried or carried into the inside of the curve. are moved, these devices, and in particular the device sum Place the new sleepers on an intermediate chassis that must be movable across the track.

The device for renewing tracks according to the present invention avoids the mentioned technical parts. It enables both in the curves, as precise and automatic centering of the devices, even on straight stretches for filing and picking up, possibly such for setting, in relation to the axis of the track.

The inventive device for renewing tracks, with a solid beam, which is hinged at both ends to a mobile support

109884/0184

is, with one support on the old and the other on the new track is, the beam at least part of the necessary equipment for swiveling out the old rails, removing the old sleepers, treating the track bedding to recreate the reading surface for the sleepers, setting the new sleepers and the new rails is characterized by that the two support points of the beam are supported by two exposed beams of two carriages surrounding the beam are formed that the ratios of the distances between the hinge points of this joist, the length of the exposed Part of the girder and the space between the axles or bogies of the two trolleys are selected in such a way that the longitudinal axis of the beam girder is essentially is tangent / to the axis of the track in the curves.

The devices to set the new sleepers as well as those to set down the old sleepers and to adjust the track bedding are at the tangent point the longitudinal axis of said beam with the axis of the track is arranged. In a preferred embodiment of the subject matter of the invention, these are Devices mounted on a support that is hinged to the beam and two screw jacks connected. This is an adjustment of the height and the transverse inclination possible in a plane that is essentially perpendicular to The axis of the track is at a standstill. With the device described, the thresholds are thus at right angles and symmetrically with respect to the longitudinal axis of the beam and set with the desired inclination so that in the curves the axis of each sleeper coincides with the radius of curvature of the track.

This arrangement on a single support for the depositing devices, Adjustment and deployment is not required, although it has significant advantages. The individual devices could also be used independently of one another and adjust individually.

An exemplary embodiment of the subject matter of the invention is given below on hand the drawings explained in more detail. Show it :

Figure 1 is a schematic view of the bar on the two RoIlscheneln is articulated on a curved section of track;

Figure 2 ■ the geometric behavior of the device shown in Figure 1;

FIG. 3 shows a side view of the device according to the invention with the

109884/0184

Equipment parts of the hinged beam and

FIG. 4 is a view of part of the device shown in FIG.

In Figures 1 and 2, the four points 1, 2, 3 and 4 represent the axis of rotation the bogie - the two roller bolsters 5 and 6, while points 7 and 8 the two outermost joints of the beam 9 on the beams Io and 11 of the same Represent carriages 5 and 6.

The longitudinal axis of the track is shown here by the circular arc xy.

The projection of all the points mentioned above to the plane of the track results in the representation, as is shown in FIG 2, which is clearly visible that for equal proportions of segments a, b, c, d, and o are represented by the distances between the joints of the beam are formed, between the bogies of the roller stool and the length of the beam, the projection axis (7-8) of the beam on the plane of the track is always tangent to the axis xy of the track, in a point T, regardless of Radius of curvature OT of the track.

In this figure, the tangent point T is located in the middle of segment a, which represents the length of the beam 9. However, this construction is not conditional} one can therefore place the tangent point T in any position between the hinge points Select 7 and 8 of the bar and the proportions of the segments accordingly change.

In FIG. 3, only the two ends Io and II are in the form of one exposed "beam, with two carriages 5 and 6 surrounding the beam 9. This simplified representation should not unnecessarily burden the drawing.

When operating the device, this shifts in the direction of the one shown Arrow. The beam 9 is on the carrier Io of the carriage 5 by means of a Double joint 7 articulated, whereby each rotation of the carrier and the carriage 5 in a plane across the track is prevented. The other end of the beam is hinged to the support 11 of the carriage 6 by means of a ball joint O. Under this bar 9, a beam 12 is attached, which is supported at the front at an articulation point 13, which is itself held by a column beam 14 fastened under the beam 9. To the rear, the carrier 12 is located on two points on both sides of the track.

109884/0184

th held by means of two vertical screw screws 15. This carrier 12 is likewise shown in the figure 4, schematically and with _ü jstrichelten lines. _k The Differentialode * r parallel action of the two screw jacks 15 allows adjustment of the position of the carrier 12 in a plane which is substantially perpendicular with respect to the track, wherein the lateral deflection can be of the carrier fixed by any known per se means.

Seen from the front, the following parts are attached to this carrier:

a device for parking the old sleepers 16, here is represented by a circular sliding member 17 which engages in the sleepers, which by a wheel 18 of a first transport member s 19 can be taken along; · ■

a device 2o for adjusting the track bed}

a device 21 for setting the new sleepers 22, which are fed by a second transport element 25 *

The transport member 19 moves the old sleepers against the carriage 5 * wo they are taken up and placed in the storage trolley, not shown.

The adjustment devices and the setting devices of the new Schwöllen are of course placed in the tangent point T described above.

In this FIG. 3, guide devices 40 and 41 are also shown schematically shown, which are arranged on both sides of the suspended beam. These Devices are used to lift and swivel the rails. The mode of action These devices are shown in FIG.

The first device 4o, seen in the direction of movement of the train, enables due to the various roles 24, 25 and 26 a lifting and pivoting the old rails 27, which then, for example, lift the track, are parked can be.

The second device 41 allows with the help of the rollers 28, 29, 3o and 31 a lifting of the new rails 32, which for the time being, for example, on both sides of the other track, as well as bringing about these rails, around them at the predetermined normal interval with respect to each other to the new To lower thresholds.
