In der Zeichnung ist mit 1 ein an sich bekannter Schwellenfachräumer bezeichnet, der in Richtung des Pfeiles »F« über das Gleis verfahren wird. An der rückwärtigen Seite dieses Schwellenfachräumers sind Räumwerkzeuge 2 angeordnet, die heb- und senkbar sind und in den Schotter eingestoßen werden und diesen nunmehr, wie dies besonders deutlich F 1 g. 2 zeigt, nach außen zu den Bettungsflanken fördern. In the drawing, 1 is a known threshold compartment clearer which is moved over the track in the direction of the arrow "F". At the rear side of this threshold space clearer are arranged broaching tools 2, which can be raised and lowered and pushed into the gravel and this now, how this is particularly clear F 1 g. 2 shows promote outward to the bedding flanks.

Unterhalb des Schwellenfachräumers ist ein Hydraulikzylinder 3 gelagert, dessen Kolbenstange 4 an eine Verbindungsstange 5 anschließt, die an ihrem der Verbindung mit der Kolbenstange 4 abgewandten Ende eine Schubstange 6 bei 7 gelenkig trägt. Die Schubstange 6 ist an ihrem vorderen, mit der zu verschiebenden Schwelle in Kontakt kommenden Ende L-förmig ausgebildet, wobei der Schenkel8 sich auf die Oberseite einer Schwelle 10 und der Schenkel 9 sich an die Stirnseite der Schwelle 10 anlegt. Bei Betätigen des Hydraulikzylinders wird nunmehr die Schwelle 10, nachdem vorzugsweise die Schwellenbefestigungen etwas gelockert sind, entgegen der Arbeitsrichtung des Schwellenfachräumers verschoben.A hydraulic cylinder 3 is mounted below the threshold compartment clearer, whose piston rod 4 is connected to a connecting rod 5, which at its the connection facing away with the piston rod 4 End of a push rod 6 at 7 articulated. The push rod 6 is in contact at its front with the threshold to be moved coming end L-shaped, with the leg8 on top a threshold 10 and the leg 9 rests against the face of the threshold 10. When the hydraulic cylinder is actuated, the threshold 10 is now preferably the threshold fastenings are somewhat loosened, contrary to the working direction of the Threshold compartment clearer postponed.

Um ein paralleles Verschieben der Schwellen sicherzustellen, sind vorzugsweise an jeder Seite der Maschine je eine Schubstange 6 mit zugeordnetem Hydraulikzylinder 3 vorgesehen. To ensure that the sleepers move in parallel, preferably a push rod 6 with an associated one on each side of the machine Hydraulic cylinder 3 is provided.

In Fig. 1 ist ein portalartiger Träger 11 dargestellt, der ein allgemein mit 12 bezeichnetes Planiergerät trägt. Dieses Planiergerät besteht aus quer zur Gleislängsachse keilförmig ausgebildeten Profilstäben 13, 14 und 15, die beim Vorschub der Maschine in Richtung des Pfeiles »F« über den Schotter gezogen werden und dadurch den Schotter einebnen. In Fig. 1, a portal-like carrier 11 is shown, which is a general with 12 designated leveler carries. This leveler consists of across the Longitudinal track axis wedge-shaped profile rods 13, 14 and 15, which during the advance the machine can be pulled over the ballast in the direction of the arrow »F« and thereby level the gravel.

Claims

Claims: 1. A method for clearing ballast from track beds by moving the ballast from the center of the track to the bed flanks below Use of so-called threshold space clearers with clearing tools, characterized in that that before the use of the broaching tools of the threshold space clearer in the area of Broaching tools located threshold or thresholds by one through the distance between the thresholds mutually defined dimension in the track bed space previously cleared of ballast be moved.

2. Device for performing the method according to claim 1, characterized by means of a known threshold compartment scraper (1) on both sides the rails on the sleeper head engaging push rods (6) to move the sleepers (10) against the working direction of the threshold compartment clearer (1).

3. Apparatus according to claim 2, characterized in that the push rods (6) can be operated hydraulically.

4. Apparatus according to claim 2 or 3, characterized in that the end of each push rod (6) which comes into contact with the threshold (10) essentially Is L-shaped, such that in the working position of the push rod one leg (8) of the "L" on the top of the threshold (10) and the other leg (9) of the "L" is on the rear side surface as seen in the thrust direction of the threshold (10) the threshold.

5. Apparatus according to claim 3 or 4, characterized in that each push rod (6) with a hydraulic cylinder arranged on the threshold compartment scraper (1) (3) is connected and in the rest position in a raised position under the threshold compartment clearer is retractable.

6. Device according to one of claims 2 to 5, characterized by one in the direction of travel of the vehicle the broaching tools (2) following, from across to Longitudinal track axis wedge-shaped profile bars (13, 14, 15) existing leveling device (12).

The invention relates to a method for clearing the ballast from track bedding by moving the ballast from the track center to the bedding flanks using so-called threshold clearers with broaching tools. Continue to refer the invention relates to an apparatus for performing this method.

In a known method for clearing the ballast in track beds The procedure is that the ballast is placed under the track grid using a scraper chain away and conveyed into a cleaning sieve via a conveyor tine in the same operation will.

The crushed stone cleaned in this cleaning sieve is then again conveyed back into the track grid.

In another known method, only the one next to the track grid is used existing gravel taken and cleaned. This procedure points to the former has various advantages for operational reasons. In this known method, the cleaning can be done on the gravel, which is between the cross sleepers of the track is to be expanded by the fact that in front of the Execution of the process causing flank cleaning machines by means of a Another device cleared the ballast from the sleeper compartments to the bed flank will.

Machines that enable this process point transversely to the longitudinal axis working broaching tools that are used in the gravel of a sleeper compartment and promote this gravel to the bedrock flanks. That way will the gravel moved to the side, but only from the sleeper compartment, so that the one below Gravel remaining on the sleeper cannot be cleaned.

The invention is based on the object, following on from the last called procedure to expand this procedure so that the gravel underneath the sleepers are also taken up by the broaching tools and to the bedding flanks can be promoted where he is now using the well-known bedding flank cleaning machines is cleaned.

The method proposed to solve this problem is thereby characterized that before the use of the broaching tools of the threshold compartment clearer the Threshold or thresholds located in the area of the broaching tools by a The distance between the sleepers is defined as the amount previously cleared from the ballast The space of the track bed can be moved.

The apparatus for performing this process is essentially characterized by arranged on a known threshold compartment scraper, Push rods attacking the sleeper head on both sides of the rails to move the threshold opposite to the working direction of the threshold clearer. Here can the procedure is preferably such that the push rods can be actuated hydraulically are.

In order to enable the threshold to be gripped safely, according to Another feature of the invention proposed that the threshold in Contact coming end of each push rod is essentially L-shaped, in such a way that one leg of the "L" is in the working position of the push rod the top of the threshold and the other leg of the "L" are in the direction of thrust Seen the threshold rests the rear side surface of the threshold. Every push rod is preferably with a hydraulic cylinder arranged on the threshold compartment scraper connected and is in the rest position in a raised position under the threshold compartment clearer retractable.

According to a further essential feature of the invention, finally a leveling device is provided, the clearing tools seen in the direction of travel of the vehicle and consists of wedge-shaped profile bars transverse to the longitudinal axis of the track.
