Description

auf die Fahrwerke des Gerätes quer zur Fahrtrichtung wirkenden Horizontalkräfte klein gehalten werden. Horizontal forces acting transversely to the direction of travel on the chassis of the device are kept small.

Die Lösung dieser Aufgabe besteht nach der Erfindung darin, daß der Tragbalken in seinem mittleren Bereich U-förmig nach unten gekröpft ausgebildet und mit seinen Enden um vertikale Achsen schwenkbar auf einem vorderen und einem hinteren Fahrgestellrahmen abgestützt ist, daß das Räumwerkzeug am Ausleger mittels eines an dem der Lagerung an dem Tragbalken entgegengesetzten Ende des Auslegers in dessen Schwenkebene schwenkbar angeordneten Werkzeugstieles angeschlossen und um die Achse des Werkzeugstieles drehbar ist, und daß das Schleuderrad von dem Laufwerk über ein Getriebe antreibbar ist.The solution to this problem is, according to the invention, that the supporting beam in its middle Area U-shaped bent downwards and pivotable with its ends about vertical axes is supported on a front and a rear chassis frame that the broach on the boom by means of an end of the boom opposite to that of the bearing on the support beam connected in the pivot plane pivotably arranged tool handle and around the axis of the tool handle is rotatable, and that the centrifugal wheel can be driven by the drive via a transmission is.

Hierdurch wird erreicht, daß der Schwerpunkt des Gerätes nahe der Fahrebene liegt und daß das Eigengewicht des Räumwerkzeuges, des Werkzeugstieles und des Auslegers zum größten Teil vom Laufwerk des Räumwerkzeuges aufgenommen wird, so daß die Fahreigenschaft und Entgleisungssicherheit der Fahrgestelle des Gerätes verbessert werden.This ensures that the center of gravity of the device is close to the driving plane and that its own weight the broach, the tool handle and the boom for the most part from the drive of the broaching tool is added, so that the driving characteristics and derailment safety of the chassis of the device can be improved.

Das Getriebegehäuse kann ein mit dem unteren Ende des Werkzeugstieles fest verbundenes äußeres Gehäuse und ein inneres Gehäuse aufweisen, die gegeneinander mittels eines Schneckentriebes einstellbar verbunden sind. Ferner kann das Räumwerkzeug mit einer Pflugschar versehen sein, die an der Stirnseite eines Halses des inneren Gehäuses befestigt ist, durch den eine Welle nach außen verläuft, die das Schleuderrad trägt.The gear housing can be an outer one firmly connected to the lower end of the tool handle Housing and an inner housing, which can be adjusted against one another by means of a worm drive are connected. Furthermore, the broaching tool can be provided with a ploughshare that is attached to the end face a neck of the inner housing through which a shaft extends outwardly, which the Centrifugal wheel carries.

Auf zwei zweiachsigen Fahrgestellrahmen 1, 2 ist in Drehpfannen 3 ein in seinem mittleren Bereich U-förmig nach unten gekröpfter Tragbalken 4 kardanisch beweglich gelagert, der die Zug- und Druckkräfte eines an einer Kupplung eines der Fahrgestellrahmen 1 oder 2 angreifenden nicht dargestellten Triebfahrzeuges überträgt. Auf dem nach unten gekröpften Teil des Tragbalkens 4 ist in Lagerstellen 5 und 6 ein rahmenartiger Ausleger 7 angeordnet,On two biaxial chassis frames 1, 2 in pivot pans 3 is a U-shaped in its central area downwardly cranked supporting beam 4 gimbal mounted movably, which the tensile and compressive forces one acting on a coupling of one of the chassis frames 1 or 2, not shown Traction vehicle transmits. On the downward cranked part of the support beam 4 is in bearings 5 and 6 a frame-like boom 7 is arranged,

Das untere Teil des Werkzeugstieles 13 ist in Arbeitsrichtung nach hinten abgebogen und trägt ein Räumwerkzeug 15, an dem außer einem Handrad 16 noch ein Sitz 17 für einen Bedienenden angeordnet ist.so the axis of the tool handle 13 is adjustable. The lower part of the tool handle 13 is in the working direction bent backwards and carries a broaching tool 15 on which, in addition to a handwheel 16, is still a seat 17 is arranged for an operator.

as Das Räumwerkzeug 15 weist ein mit dem unteren Teil des Werkzeugstieles 13 fest verbundenes äußeres Gehäuse 18 auf, das ein inneres Gehäuse 19 umgibt, die beide mit einem Schneckentrieb 20 gegeneinander über das Handrad 16 einstellbar sind. Eine auf beiden Seiten des Gehäuses 18 herausragende Welle 21 ist an ihren Enden mit je einem Rad 22 mit griffigem Gummiprofil versehen. Im Gehäuse 19 ist ein Kegelradgetriebe 23 angeordnet, von dem ein Kegelrad auf der Welle 21 sitzt, während ein Kegelritzel auf einer in Fahrtrichtung weisenden Welle 24 sitzt, die durch einen Hals 25 des Gehäuses 19 nach außen verläuft und an ihrem vorderen Ende mit einem Schleuderrad 26 versehen ist. An der Stirnseite des Halses 25 ist eine Pflugschar 27 befestigt, die dem Profil des zu räumenden Grabens angepaßt ist.The broach 15 has a with the lower Part of the tool handle 13 fixedly connected outer housing 18 which surrounds an inner housing 19, both of which can be adjusted against each other with a worm drive 20 via the handwheel 16. One on both Sides of the housing 18 protruding shaft 21 is at its ends with a wheel 22 with good grip Provided with rubber profile. In the housing 19 a bevel gear 23 is arranged, of which a bevel gear on the shaft 21 sits, while a bevel pinion sits on a shaft 24 pointing in the direction of travel, which passes through a neck 25 of the housing 19 extends outwardly and at its front end with a centrifugal wheel 26 is provided. At the end of the neck 25, a ploughshare 27 is attached to the profile of the to is adapted to clearing trench.

This devices are hinged for clearing un-swiveling frames, and are provided with watering ditches from railroad tracks that are not very suitable for a rotatable or steerable clearing tool. Since in the area of the railway tracks there is often a short one, which has a centrifugal wheel and a pair of wheels, the clearing tools are necessary at intervals for railway operation in stationary auxiliary devices lowered to the side and the position on the trench bottom rolls.
