Abstract

Two vertically movable tool carriers (3, 4) are provided which with the aid of hydraulic units (5, 6) can be moved transverse to the longitudinal direction of the rails and in the longitudinal direction of the sleepers (1). Each tool carrier has two swivably mounted tools (7, 8 and 9, 10) which can independently be swivelled around an axis (e.g. 11) running parallel to the rail's longitudinal axis so as to place the tool in a non-operational position relative to the rails (2, 14) which form part of the railway points. In a preferred design the tools are secured by hooks etc. in the non-operative condition, and they can be moved into this position using pneumatic, hydraulic, or electrical auxilaries.

Description

"Device for clearing the ballast from track bedding" The invention refers to a device for clearing 'the ballast from track beds by means of carried by a work machine, can be raised and lowered and is parallel to the longitudinal axis of the sleeper movable clearing tools, the working tools that work inside and outside the track wear.

So-called threshold compartment clearers are known and consist of one Working machine movable on the track, which carries broaching tools. These broaching tools exist in essential from inside and outside the track at the same time effective working tools that are attached to transversely movable slides or the like. are arranged so that a transfer of the ballast from a work tool to the other work tool is possible, and the ballast of a track bed can by means of these working tools moved outwards to the flanks of the track bed where the ballast is cleaned using so-called flank cleaning machines can.

These known working machines have proven themselves, but are preparing in the area of switches or the like. Difficulties as it is not possible for that to keep the arrangement of the work tools selected on the normal track, since the Rails of the branching track hinder the movement of individual work tools. For this reason, up to now - depending on the position of these rails - the inner or outer Working tool can be removed.

The replacement of the working tools is several times for each switch to be cleared and is a time-consuming job. The work tools had to unscrewed or removed from a corresponding conical holder and due to the weight of the work tools, this work can normally can only be carried out by two people.

The invention is based on the object of the known threshold compartment clearers to be improved in such a way that quick work is also possible in the area of switches and the previously required personnel and time expenditure is avoided.

This object on which the invention is based is achieved by that every single work tool is independent of every other work tool from his effective working position into a "non-use position" and can be determined there.

In a preferred embodiment of the invention, the procedure is as follows: that the work tools are pivotably mounted transversely to the longitudinal axis of the track and, for example over hooks or the like. in the 1, non-use position "can be set.

The guidance of the working tool from the working position to the non-use position " can be done via pneumatic, hydraulic or electrical aids, whereby the required energy sources usually on the threshold clearer, i. e. that is, on the working machine.

This arrangement makes it possible to use the work tools depending on Type and formation of the switch conditions and of the track junctions to bring into a position that does not hinder the broaching movement without the need for it is that this requires time-consuming conversion work to be carried out on the machine have to.

An exemplary embodiment of the invention is described below with reference to FIG Drawing explained.

The drawing shows a schematic view of the broaching tools in the direction of the longitudinal axis of the track.

In the drawing, a sleeper 1 carrying rail 2 is shown. The broaching tools carried by a work vehicle, not shown, exist in the illustrated embodiment of two can be raised and lowered Tool carriers 3 and 4, which have hydraulic devices 5 and 6 in addition for their lifting and lowering movement transversely to the longitudinal axis of the track and in the longitudinal direction of the Threshold are seen adjustable.

The actual tool carrier 3 or 4 carries the work tools 7 and 8 or 9 and 10, these working tools in each case transversely to the longitudinal axis of the sleeper and axes aligned in the longitudinal direction of the track, one of which is shown in the drawing is denoted by 11, are pivotably mounted.

This arrangement makes it possible to use the actual work tools 7 and / or 8 and / or 9 and / or 10 to those shown for the work tools 8 and 10 "Pivot non-use position, with the work tools in this position can be set for example via hooks 12 or 13.

The rails of the normal track are in the drawing with 2 and the Rails of the branching track denoted in the drawing with 14 to the mode of operation to illustrate the device according to the invention.

In the illustrated embodiment, the inner tool 8 is the Tool carrier 4 and the outer tool lo 3.

of the tool carrier is folded in and it is already out of the drawing to see that this causes the clearing movement of the remaining effective work tools 7, 9 is not hindered.

Claims: 1. Device for clearing the ballast from track beds by means of a work machine carried, raised, lowered and parallel to the sleeper longitudinal axis of movable broaching tools that are inside and outside the Wear working tools that act on the track, characterized in that each individual Work tool (7, 8; 9, lo) independently of any other work tool from its effective working position in a "non-use position" and there is detectable. 2. Apparatus according to claim 1, characterized in that the working tools are pivotably mounted transversely to the longitudinal axis of the track.
