Description

The The invention relates to a device for changing and aligning of sleepers on track systems, in particular those which are individually to change. The field of application relates in particular to such tracks, where the sleepers are on a loose substructure, there often sunken and heavily soiled, the rails over loose Inserts (preferably so-called hammer pieces) in the on the sleepers located Oops of platings are kept and the tracks often must be moved laterally, like that in coal mines and the like make must happen. At the same time the device is suitable horizontal to align suspended tracks.

To DD 233 910 A3 a device in the sense of a flat car is known, the structures of which device parts for the transverse displacement of sleepers by means of known working cylinder with rail tongs. For anchoring the car to the track and known track lifters for lifting the track relative to the ground as well as suitable devices are available. The rail lifts are arranged at a constant distance from each other. This limits the area of application. Thresholds can only be moved if they shuttle freely. A straightening of the tracks is not possible. Overall, a complex construction is noted, the main component is a platform whose length is significantly greater than their width.

In DE 1 658 360 A1 there is described a sill rebuilding device which is suitable for normal railroad tracks including removal and reintroduction of the ballast and which may be referred to as a rebuild train. For other examples of this kind, let's take a look at other solutions DE 27 20 064 C2 directed.

Of Another was to facilitate the threshold change in the case low demand, a construction machine, such as an overhead loader, with an attachment which is able to grip rails or sleepers and to turn.

task The invention was to develop a device, on the one hand in a compact design, changing individual thresholds, one longitudinal displacement the thresholds in the sense of a distance and position correction and on the other hand the Correct entire Jochlagen even under difficult terrain conditions in the absence of substructure and the resulting negative phenomena allows. A desired compact design is an uncomplicated implementation also allow without track systems.

The Task is solved by a device according to claim 1.

To inventive preferred variants can the bow-shaped reinforcement Trapezoidal on the traverse or be formed in the sense of a circular section, wherein the Extension is directed in each case to Traverse. The clear final dimension of the down directional extension is preferably chosen larger than the largest gauge a track yoke to be processed.

in the Sense of maintaining balance of power the trusses are preferably in pairs. At least a traverse is at right angles to the axis of the track yoke Leitprofile formed in which a delay device to the side lead out led loose sleepers is. The guide profile can also be designed as a roller guide

It is possible, to make this drafting device work on both sides, by exemplifying this a threaded spindle is actuated. However, this screw dirty quickly, so that a hydraulic Drive in which each Verzusgeinrichtung with the piston rod of a hydraulic cylinder connected, trouble-free and works faster anyway. However, this has the consequence that for every Side a delay device must be present.

A further expedient embodiment according to the invention provides that the located on each piston rod of the lifting cylinder Supporting claws have an attachment point to the piston rod, the dimensional so in the upper surface each supporting claw is arranged, that at its rectangular Design to each end edge when turning the support bracket about its vertical axis at right angles to the outside another distance is given. That is advantageous if one with the adjustment the lifting cylinder gets into border areas, but the footprint of the Support braces should be further apart.

Next an operator from the seat of the device it may be expedient to control the device autonomously by the operator stands by and the event immediately inspects. That is why the Operating unit set up so that via known remote control systems a Operation should be carried out at a suitable distance from outside the device can.

A further preferred embodiment provides that the wheels carry the boom in relation to the trusses across a known adjustment to the track yoke slidably guided are designed fixed. This is the Vorrich suitable for different gauges and adjustable.

There in opencast mines and similar tracks are laid without substructure, the process of the device can become a problem when the Rails dirty or even more or less in the underground sunken. As a use of the device despite complicated Conditions with high reliability is desired, are preferred at least two of the wheels individually over preferably designed hydraulic motors drivable.

To the Achieving optimal conditions of use are also the rail clamps designed in pairs controllable.

The on the trusses existing guide profiles for in relation to Track yoke laterally extendable drafting device are far down open, that the threshold to be moved or changed to to the nearest rail brought can be. In that regard, a high degree of freedom of assembly is given.

drive unit can be an internal combustion engine that acts directly on the drive. It may as well be that of the internal combustion engine on a generator works, the battery-buffered electrical energy for all others Drives available provides. It may also be that about the internal combustion engine hydraulic Drives are excited. Of course, mixed forms are possible. As well There may be a control panel and a seat for the operator be.

The Booms point outside in their longitudinal direction trained guides for moving and controllable angle lever, which can be folded down or sideways accomplished are and about integrated suitable actuators, such as threaded shafts or the like known drives, adjustable in the direction of the axis of the track yoke accomplished are. The angle lever protrude in the folded down state up the threshold and effect over an attack on the plating or on it Oesen a shifting of the thresholds with corresponding control in the direction of the axis of the track yoke.

at extended lifting cylinders and thus elevated device is a lateral displacement of the respective located under the device Track yoke possible, by over the existing rail tongs and their pairwise simultaneous Control the track yoke slightly raised and over the pairwise, at least one on each side, existing and querverschieblich controllable Lifting cylinder, the device with the track yoke is pushed laterally far, until again a desired horizontal alignment has occurred.

at Implementation of the design features according to the invention a device has been created which is suitable for all arising Track construction works even under difficult conditions of the location of a track universally execute. Due to its design, it has a compact design and can as well without further modifications a mobile carrier, such as that a truck is to be transferred for transfer.

The Invention will be explained in more detail below using an exemplary embodiment. In the associated Show drawing
