DE1138079B - Device that can be moved on the track for lifting the track being driven on - Google Patents

Description

The invention relates to a device which can be moved on the track for lifting the track being traveled on by means of a track lifter, which supports a support device which can be lowered onto the ballast bed and organs for detecting and lifting the track. With 5 such devices so far there is a certain amount Difficulty insofar as the track is naturally not only lifted by the track lifter at that point on which the track lifter engages and the predetermined lifting dimension is monitored, but inevitably also in the area immediately adjacent to the location of the track lifter. This area extends in Work direction both backwards and forwards; the track is also raised a little where it is the track position has already been corrected, causing errors in the track position.

In order to avoid such errors or at least to reduce them, it is already known to use the track in to load the already corrected area while lifting; for example was the track lifter arranged on the front face of a heavy track tamping machine, the weight of this Machine guaranteed to maintain the track position in the already stuffed track area. For fixing the track position at intervals as preparation for the actual track tamping, i.e. the so-called Track fastenings, however, are preferably used light machines that are quickly released from the track when a train is approaching, but on the other hand with their weight for a load of the already stuffed track are not sufficient to keep this track still.

With these light machines you could put a load on the already stuffed track Carrying along or dragging ballast. However, this measure is costly and complicates the operation of the device and its suspension when a train approaches.

The aim of the invention is to reduce the weight of the raised track in addition to the load on that track area which has already been corrected and therefore during the lifting of the The track should remain at rest at a point that has not yet been corrected on the front. According to the invention this is achieved in that the support device of the track lifter at the front end of a vehicle in the longitudinal direction extending beam is arranged, the rear end of which is pivotable on the chassis frame is mounted and between the support device and the rear pivot bearing carries one or more organs for grasping the track to be lifted.

When lifting the track by means of such a device, the track is partly on the support, on the other hand, however, loaded onto the rear pivot bearing; in this back area it becomes effective as a load on the already clogged track and thus secures the rest position of the already corrected track during lifting. On the other hand, the track itself remains at the front completely unencumbered; the support device acts there only on the top of the bedding.

In the device according to the invention, it is advantageous if the organs for grasping and lifting of the track are displaceable on the carrier in the longitudinal direction of the carrier.

For the purpose of optionally changing the respective effective lever arms embodied by the carrier can within the scope of the invention, the pivot bearing of the expediently designed to be adjustable in length The carrier can be designed to be variable in its distance from the front free end. Will be expedient but this pivot bearing is arranged in the area of the rear axle of the chassis so that it is attached to this Set the weight of the machine and the weight of the track, as far as it is transferable from this axis, optimally summed up.

With a sensible and suitable configuration of the device according to the invention, when lifting of the track achieves the best possible effect and performance insofar as the machine in the area of its Rear axle the already stuffed, in real

Holds the track at the high altitude, so to speak and clamped in, so that the track jacks arranged in the front area move the track after an ideal able to deform continuous bending line. Essential for monitoring the correct predetermined The lift dimension is the rearmost track lifter, with this track lifter being expediently a device for tamping the track is assigned to the track in the predetermined raised Fix position. So that the track bar arranged further in front doesn't lift the track too high and one create a continuous bending line, the clamping pliers of such track jacks can according to the height be staggered in such a way that the clamps of the track jacks arranged further forward only later come into effect and inevitably produce less lift than the tongs downstream Track lifter.

An exemplary embodiment of the invention is illustrated in the drawing in a longitudinal view.

Here, 1 designates the chassis of the device, which is provided with a front wheel set 2 and a rear wheel set 3 is equipped. In the area of the axle of the rear wheel set 3 a carrier 4 is pivotably mounted in a pivot bearing; this pivot bearing 5 falls in the embodiment with the wheel axle or is identical to it. To support the front At the end of the carrier 4 a hydraulically actuatable cylinder 6 is provided, in which a KoI-ben slides; At the lower end of the piston rod is a support stamp that sits on the top of the bedding? arranged.

Furthermore, in the front area of the carrier 4 there is a lifting element 8 of known construction that engages the track provided, which also consists of a hydraulically actuated cylinder with piston and Piston rod consists; at the lower end of the piston rod there are track clamps or the like.

A similar lifting element 9 is approximately in the Arranged longitudinal center of the carrier 4, specifically where the correct predetermined with the device Track position is to be achieved. At this point there is also a tamping device known design to fix the track position obtained.

The rails 11 of the track to be corrected rest in the usual way on cross sleepers 12, which in turn rest on the bedding bulkhead 13.

As is also already known, for example © ine made of feeler rollers 14 and a measuring stick 15 existing device may be provided. The measuring stick 15 can be a Wear button 16, sensor od Shows the stroke. The tension wire 17 can be kept under tension by a tension pulley 18, in order to continuously establish a reference base for determining the correct one with the lowest possible slack To form stroke.

The desired effect of the track lifter is characterized in particular by the fact that when lifting of the track a more or less large part of the track weight over the carrier 4 and its Pivot bearing 5 in the area of the rear axle of the vehicle to load the already corrected track section arrives and strives to keep the track in a rest position. This effect can of course can still be favored by the fact that the construction of the entire device is as extensive as possible Shifting one's own weight to the area of the rear axle takes care; so it is expedient in particular to arrange the heavy drive units etc. of the device above the rear axle. As already mentioned, the leverage of the carrier 4 can be achieved by varying the distances between Support, track lifting device and swivel bearing changed as desired and different needs can be easily adjusted.
