Abstract

The mobile crane (1) has a wheeled chassis (3) supporting an upper carriage (4) with a boom arm (5) and a counterweight which can rotate about a vertical axis, their contours lying within the track width of the rails during movement of the mobile crane along the track. The longitudinal sides and the rear of the upper carriage are shaped to remain within a region defined by two vertical planes on either side of the track during inclination of the carriage when traveling around a cambered track section.

Description

Die Erfindung betrifft einen schienengebundenen Mobilkran mit einem auf einem Unterwagen zusammen mit einem Gegengewicht und einem Ausleger um eine vertikale Achse schwenkbar angeordneten Oberwagen, dessen Konturen innerhalb des vorgeschriebenen Lichtraumprofils einer Gleitstrecke angeordnet sind und der mit einer Vorrichtung zum Kurvenüberhöhungsausgleich ausgerüstet ist.The invention relates to a rail-bound mobile crane with one on one Undercarriage together with a counterweight and a boom around one vertical axis swiveling superstructure, its contours inside the prescribed clearance profile of a gliding track are arranged and with a device for curve elevation compensation is equipped.

Schienengebundene Mobilkrane der gattungsgemäße Art werden sowohl für Arbeiten am Gleis als auch neben dem Gleis eingesetzt; ihre Einsetzbarkeit ist stark abhängig von der Konstruktion des Kranes selbst und der Ausbildung von Ausleger und Gegengewicht. Insbesondere bei Arbeiten auf Gleisstrecken, bei denen Parallelgleise verlegt sind oder die in Tunnelstrecken verlaufen, müßten besondere Maßnahmen vorgesehen werden, um den nötigen Freiraum zum Nachbargleis oder zur Tunnelwand einzuhalten.Rail-bound mobile cranes of the generic type are used both for work used on the track as well as next to the track; their applicability is highly dependent on the construction of the crane itself and the design of the boom and Counterweight. Especially when working on tracks where there are parallel tracks are laid or which run in tunnel sections, would have to take special measures be provided to provide the necessary clearance to the neighboring track or to the tunnel wall to adhere to.

Bei Arbeiten auf zwei- oder mehrgleisigen Strecken ist aus Sicherheitsgründen unbedingt dafür zu sorgen, daß keine auskragenden Kranteile, z.B. Teile des Gegengewichtes in das Lichtraumprofil der Nachbarstrecke einschwenken. Verschiedene bekannte Krankonstruktionen sind so ausgelegt, daß die Konturen des Oberwagens auch während des Kraneinsatzes innerhalb des von dem jeweiligen Streckenbetreiber vorgeschriebenen Lichtraumprofiles der Gleisstrecke verbleiben.When working on two or more tracks, this is for safety reasons make absolutely sure that no cantilevered crane parts, e.g. Parts of the Swing the counterweight into the clearance profile of the neighboring route. Various known crane designs are designed so that the contours of the Upper carriage also during the crane operation within that of the respective Track operators have the required clearance profile of the track section.

Problematisch wird es dann, wenn zwar die Krankonturen das Lichtraumprofil einhalten, doch aufgrund von Gleisüberhöhungen in Kurvenstrecken ein auf dem Nachbargleis fahrendes Schienenfahrzeug sich seitlich neigt und dadurch in den Lichtraumprofilbereich des im Einsatz befindlichen Eisenbahnkranes gelangt. Beim Einsatz wird üblicherweise aus Stabilitätsgründen und Gründen einer definierten Schwerpunktlage der Eisenbahnkran in die Horizontale ausgerichtet, wozu der sogenannte Kurvenüberhöhungsausgleich vorgesehen ist. Durch diesen Ausgleich wird der Oberwagen mit dem Ausleger und dem Gegengewicht gegenüber dem Fahrwerk des Kranes, das sich auf einer überhöhten, d.h.geneigten Gleisstrecke befindet, so weit verschwenkt,.bis sich die Schwenkachse des Kranes senkrecht steht. Durch dieses gegenüber der Gleisstrecke erfolgte Aufrichten des Kranes verschiebt aber die Kontur des Oberwagens innerhalb des Lichtraumprofiles, so daß es zur Kollision mit den auf dem Nachbargleis fahrenden Fahrzeugen kommen könnte.It becomes problematic when the crane contours have the clearance profile adhere to, but due to track cant in curve sections on the Rail vehicle running on the adjacent track tilts sideways and thereby into the Clearance profile area of the railway crane in use arrives. At the Use is usually defined for reasons of stability and for reasons of stability Center of gravity of the railroad crane aligned horizontally, which is why so-called curve elevation compensation is provided. Through this compensation the superstructure with the jib and the counterweight is opposite the Chassis of the crane, which is on an elevated, i.e. inclined, track section is pivoted until the pivot axis of the crane is vertical. Due to this erection of the crane, which took place opposite the track, shifts but the contour of the superstructure within the clearance profile, so that it is Collision could occur with the vehicles running on the neighboring track.

Aufgabe der vorliegenden Erfindung ist es, einen schienengebundenen Mobilkran der gattungsgemäßen Art so zu gestalten, daß dieser auch auf Gleisstrecken mit Gleisüberhöhung sicher und ohne Einschränkung der Traglast einsetzbar ist.The object of the present invention is to provide a rail-bound mobile crane Generic type to be designed so that it also on track sections Track cant can be used safely and without restriction of the load.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, daß die Längsseiten und der rückwärtige Teil des Oberwagens derart gestaltet sind, daß in jeder Schwenkstellung alle Konturen des Oberwagens innerhalb eines Bereiches liegen, der beidseitig der Kranlängsachse durch zwei gedachte Ebenen begrenzt ist, die von der Unterkante des Oberwagens ausgehend jeweils mindestens um einen Winkelbetrag aus der Vertikalen nach Innen geneigt sind, der dem Winkelbetrag der maximal zulässigen Gleisüberhöhung entspricht.To solve the problem, the invention proposes that the long sides and the rear part of the superstructure are designed so that in each Swivel position all contours of the superstructure lie within a range that is delimited on both sides of the longitudinal axis of the crane by two imaginary levels, which are separated from the Lower edge of the superstructure starting at least by an angle are inclined inwards from the vertical, which is the angular amount of the maximum permissible track elevation corresponds.

Durch die Gestaltung des Mobilkran -Oberwagens wird die Kontur des Kranes auch bei aufgerichteter Arbeit in Gleisüberhöhungsstrecken stets innerhalb des Lichtraumprofiles der Gleisstrecke gehalten, so daß Kollisionen mit Fahrzeugen auf benachbarten Gleisen oder im Fall von Tunnelstrecken von Tunnelwänden sicher verhindert werden. Der Eisenbahnkran bleibt durch diese Maßnahmen auch bei Gleisüberhöhungen im gesamten 360°-Arbeitsbereich einsatzfähig, ohne die ausgewiesene Tragfähigkeit zu beschränken.The contour of the crane is also enhanced by the design of the mobile crane uppercarriage upright work in track elevation always within the Clearance profile of the track section kept, so that collisions with vehicles neighboring tracks or in the case of tunnel sections of tunnel walls be prevented. The railway crane remains with these measures Track elevations can be used in the entire 360 ° working area, without the limit the stated load-bearing capacity.

Vorzugsweise ist nach einem weiteren Merkmal der Erfindung vorgesehen, daß die Längsseiten des Oberwagens und die rückwärtige Seite des Gegengewichtes in den gedachten geneigten Ebenen verlaufen. Auf diese Weise läßt sich das volle zur Verfügung stehende Profil ausnutzen. According to a further feature of the invention it is preferably provided that the Long sides of the uppercarriage and the rear side of the counterweight in the imaginary inclined planes. In this way, the full Use the available profile.

Erfindungsgemäß ist nach einem weiteren Merkmal die maximale hintere Ausladung des Oberwagens gleich oder kleiner der halben Breite des Kranes. Dieses Merkmal stellt sicher, daß beim Verschwenken des Oberwagens niemals ein Teil des Oberwagens aus der erfindungsgemäß vorgeschlagenen gedachten Ebene herausragt, die den Bereich der Krankontur festlegt.According to a further feature, the maximum rear projection is according to the invention of the superstructure is equal to or less than half the width of the crane. This characteristic ensures that when swiveling the uppercarriage never part of the Upper carriage from the imaginary level proposed according to the invention protrudes, which defines the area of the crane contour.

Dies gilt insbesondere für das Merkmal, daß das Gegengewicht des Kranes nicht über die die Kontur des Oberwagens begrenzenden gedachten Ebenen hinausragt.This is especially true for the feature that the crane's counterweight does not have the imaginary planes that delimit the contour of the uppercarriage.

Die Erfindung entspricht somit den verschärften vorgegebenen Sicherheitsbestimmungen für den Einsatz von schienengebundenen Mobilkranen. Sie ermöglicht den uneingeschränkten Einsatz des Kranes in Kurvengleisstücken mit Überhöhungsausgleich, wobei die ausgewiesene Tragfähigkeit immer genutzt werden kann.The invention thus corresponds to the tightened specified Safety regulations for the use of rail-bound mobile cranes. she enables unrestricted use of the crane in curved track sections Cant compensation, whereby the declared load-bearing capacity is always used can.
