Abstract

In known stationary or semi-suspended rescue baskets, in particular those whose pivot axis is situated outside the axis through the centre of gravity, high displacement forces occur which are necessary for swinging the basket, with respect to the ladder, in the different working positions and in the non-used position. The high displacement forces for the most part require plurality of drive units together with a comparatively high energy requirement. The rescue or work basket (2) comprises, at the least, one rotary bar (5), preferably outside the pivot axis (1) of the rescue basket (2). This means that particularly the drive for displacing the basket can be of small design. <IMAGE>

Description

Die Erfindung betrifft einen Rettungs- und/oder Arbeitskorb, der am oberen Ende einer schwenkbaren Drehleiter, eines ausschiebbaren Mastes od.dgl. über ein Gehänge angelenkt ist.The invention relates to a rescue and / or work cage or the like at the upper end of a pivotable aerial ladder, an extendable mast. is articulated via a hanger.

Es ist bekannt, an der Leiterspitze einer Drehleiter, ins­besondere einer Feuerwehrleiter, einen Rettungskorb in einer hängenden Anordnung zu befestigen, wobei die Aufhängung und die Anlenkachse sich in der Schwerpunktachse befinden. Dadurch ist keine platzsparende Anordnung an der Leiter­spitze möglich. Der Korb steht über die Leiterspitze hin­aus.It is known to attach a rescue cage to the ladder tip of a turntable ladder, in particular a fire ladder, in a hanging arrangement, the suspension and the articulation axis being in the center of gravity. This means that no space-saving arrangement at the tip of the conductor is possible. The basket protrudes from the top of the ladder.

Eine weitere bekannte Ausführung ist der stehende oder halb­hängende Rettungskorb mit außerhalb der Schwerpunktachse befindlicher Anlenkachse. Hierbei treten besonders hohe Verstellkräfte auf, die für eine Senkrechtstellung des Kor­bes innerhalb des Aufrichtwinkels der Leiter unabdingbar sind. Ein großer Nachteil ist die hierfür erforderliche hohe Verstellenergie an der Leiterspitze. Grundsätzlich werden zwei Hydroaggregate für einen Antrieb benötigt, de­ren elektrischer Energiebedarf vergleichsweise groß ist.Another known embodiment is the standing or semi-hanging rescue cage with a pivot axis located outside the center of gravity. Particularly high adjustment forces occur here, which are essential for the vertical positioning of the basket within the upright angle of the ladder. A major disadvantage is the high adjustment energy required at the tip of the conductor. Basically, two hydraulic units are required for a drive, the electrical energy requirement of which is comparatively large.

Aufgabe der Erfindung ist die Schaffung eines Rettungs- und/oder Arbeitskorbs der eingangs genannten Art, der ein­fach aufgebaut ist und mit sehr geringer Verstellenergie betrieben werden kann.The object of the invention is to provide a rescue and / or work basket of the type mentioned, which is simple in construction and can be operated with very little adjustment energy.

Gelöst wird die der Erfindung zugrundeliegende Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Mit­tel.The object on which the invention is based is achieved by the means specified in the characterizing part of claim 1.

Vorteilhaft weitergebildet wird der Erfindungsgegenstand durch die Merkmale der Unteransprüche 2 bis 8.The subject of the invention is advantageously further developed by the features of subclaims 2 to 8.

Wesen der Erfindung ist die Anordnung zumindest eines Dreh­stabs parallel zur Anlenkachse des Rettungs- und/oder Arbeits­korbes, wobei der Drehstab zwischen Korb und Korbgehänge fixiert ist.The essence of the invention is the arrangement of at least one torsion bar parallel to the articulation axis of the rescue and / or work cage, the torsion bar being fixed between the basket and the basket hanger.

Vorzugsweise sind zwei im wesentlichen gleich ausgebildete Drehstäbe in im wesentlichen spiegelbildlicher Anordnung bezüglich der Breitenerstreckung des Korbes vorgesehen.Preferably two essentially identical torsion bars are provided in an essentially mirror-image arrangement with respect to the width of the basket.

Der oder die Drehstäbe sind in der Lage, im Arbeitsbereich der Leiter (-15° bis +75° Aufrichtwinkel) das Gewichtsmoment des Rettungskorbes und einen Teil der Nutzlast (resultierend aus dem Eigengewicht Korb + Nutzlast mal Hebelarm zur Dreh­achse) aufzunehmen und dadurch die externe Energiezufuhr für den notwendigen Verstellmechanismus des Korbes wesent­lich zu reduzieren bzw. einzusparen. Es wird mithin die kinetische Energie von der Fahrstellung (Korb über Leiter­satz geschwenkt) in die Arbeitsstellung ausgenutzt. Diese Bewegung erfolgt in der Regel immer ohne Nutzlast. Daraus ergibt sich für den Verstellmechanismus ein Energieüber­schuß, welcher nun zum Vorspannen der Drehstäbe genutzt wird.The torsion bar (s) are able to accommodate the weight moment of the rescue cage and part of the payload (resulting from the weight of the cage + payload times lever arm to the axis of rotation) in the working area of the ladder (-15 ° to + 75 ° upright angle) and thereby the external one To significantly reduce or save energy supply for the necessary adjustment mechanism of the basket. The kinetic energy from the driving position (basket swung over the ladder set) into the working position is therefore used. This movement is usually done without a payload. This results in an energy surplus for the adjustment mechanism, which is now used to pretension the torsion bars.

Aufgrund des geringen Bedarfs an Verstellenergie genügt in vorteilhafter Weiterbildung der Erfindung ein einziges Hydroaggregat zum Verschwenken des Korbes. Ein zusätzliches Hydroaggregat einschließlich der zugehörigen Energieversor­gungsleitung vom Getriebe bis zur Leiterspitze kann damit entfallen (Kabeltrommel oder Hydroleitung). Der Rettungs- und/oder Arbeitskorb kann an der Leiterspitze durch Über­klappen über den Leitersatz platzsparend angeordnet werden.In an advantageous further development of the invention, a single hydraulic unit is sufficient to pivot the basket due to the low need for adjustment energy. An additional hydraulic unit including the associated power supply line from the gearbox to the tip of the conductor can thus be omitted (cable drum or hydraulic line). The rescue and / or work cage can be arranged in a space-saving manner at the tip of the ladder by folding over the ladder set.

Dies geht mit einer Verkürzung der Fahrzeuggesamtlänge ein­her. Von Vorteil ist ferner die gute Raumausnutzung des Rettungskorbes, beispielsweise die Anordnung einer Kranken­trage, deren Lagerung einfach angebracht werden kann bei einer optimalen Verschwenkbarkeit der Trage.This is accompanied by a reduction in the overall length of the vehicle. Another advantage is the good use of space in the rescue cage, for example the arrangement of a stretcher, the storage of which can be easily attached while the stretcher is optimally pivotable.

Die Erfindung wird nachfolgend anhand eines Ausführungs­beispiels unter Bezugnahme auf die beigefügte schematische Zeichnung näher erläutert; es zeigt:

  • Fig. 1 die Anordnung eines Rettungskorbes in schematischer Seitenansicht halbhängend in der Nichtbenutzungs- oder Fahrstellung A, in der 0°-Arbeitsstellung B sowie in der 75°-Arbeitsstellung C, und
  • Fig. 2 den Rettungskorb nach Fig. 1 in der 0°-Arbeitsstel­lung B in schematischer Draufsicht.
The invention is explained below using an exemplary embodiment with reference to the accompanying schematic drawing; it shows:
  • Fig. 1 shows the arrangement of a rescue cage in a schematic side view semi-hanging in the non-use or driving position A, in the 0 ° working position B and in the 75 ° working position C, and
  • Fig. 2 shows the rescue cage according to Fig. 1 in the 0 ° working position B in a schematic plan view.

Der Rettungskorb (2) ist über ein Schwenkgetriebe (4) und zwei Drehstäbe (5) am Korbgehänge (3) des obersten Leiter­teils der Drehleiter (8) befestigt. Die beiden im wesent­lichen gleich ausgebildeten spiegelbildlich angeordneten Drehstäbe (5) befinden sich außerhalb der Anlenkachse (1) des Rettungskorbes (2). Beide Schwenkgetriebe (4) werden durch einen gemeinsamen Hydroantrieb (7) angetrieben, um die Schwenkbewegung des Korbes bezüglich der Drehleiter (8) durchzuführen.The rescue cage (2) is attached to the basket hanger (3) of the uppermost ladder part of the turntable ladder (8) via a swivel gear (4) and two torsion bars (5). The two torsion bars (5), which are essentially of the same mirror-image design, are located outside the articulation axis (1) of the rescue cage (2). Both swivel gears (4) are driven by a common hydraulic drive (7) in order to carry out the swiveling movement of the basket with respect to the turntable ladder (8).

Die Anordnung und Fixierung der Drehstäbe (5) am Korb und am Gehänge (3) ist nun so getroffen, daß die Drehstäbe (5) bei einer horizontalen Nichtbenutzungsstellung (A) des Kor­bes (2) und der Leiter (8) im wesentlichen entlastet sind, d.h. in der Fahrstellung einer Feuerwehrleiter.The arrangement and fixation of the torsion bars (5) on the basket and on the hanger (3) is now such that the torsion bars (5) are substantially relieved in a horizontal non-use position (A) of the basket (2) and the ladder (8) , ie in the driving position of a fire department ladder.

Wird der Korb (2) aus seiner vorgenannten Nichtbenutzungs­stellung (A) in die 0°-Arbeitsstellung (B) mit Hilfe des einzigen Hydroantriebs (7) in Verbindung mit den beiden Schwenkgetrieben (4) geschwenkt, so werden die beiden Dreh­stäbe (5) vorgespannt. Durch den Achsabstand zwischen der Anlenkachse (i) des Rettungskorbes (2) und dem Drehpunkt der Drehstäbe (5) resultiert ein geringer Drehstab-Verstell­winkel. Während der Schwenkbewegung überträgt das am Korb (2) fest montierte Schwenklager (6) die Federkraft der Dreh­stäbe (5) auf beiden Seiten, da die Drehstäbe (5) jeweils am Gehänge (3) fest eingespannt sind. Die vorgenannte Schwenk­bewegung zwischen der Nichtbenutzungsstellung (A) und der 0°-Arbeitsstellung (B) des Korbes erfolgt ohne Nutzlast. Die Vorspannung der Drehstäbe (5) ist so ausgelegt, daß das Lastmoment des Korbes in der 0°-Arbeitsstellung (B) und ein Teil der Nutzlast für den Verstellmechanismus an­nähernd gleich Null wird.If the basket (2) is pivoted from its aforementioned non-use position (A) into the 0 ° working position (B) with the aid of the single hydraulic drive (7) in connection with the two swivel gears (4), the two torsion bars (5) are prestressed . The axial distance between the articulation axis (i) of the rescue cage (2) and the pivot point of the torsion bars (5) results in a small torsion bar adjustment angle. During the swiveling movement, the swivel bearing (6) fixed to the basket (2) transmits the spring force of the torsion bars (5) on both sides, since the torsion bars (5) are firmly clamped to the hanger (3). The aforementioned swiveling movement between the non-use position (A) and the 0 ° working position (B) of the basket takes place without a payload. The pretension of the torsion bars (5) is designed so that the load torque of the basket in the 0 ° working position (B) and part of the payload for the adjustment mechanism become approximately zero.

Wird der Korb weiter in die 75°-Arbeitsstellung (C) bewegt, bleibt das Rückstellmoment der Drehstäbe (5) annähernd kon­stant, da sich der Hebelarm des Schwenklagers bezüglich der Anlenkachse (1) des Korbes (2) verringert unter gleich­zeitiger Zunahme der Rückstellkraft der Drehstäbe (5). Hier­bei beschreibt das Schwenklager (6) einen engeren Kreis­bogen und verschiebt sich axial auf dem Drehstab. Der Korb (2) erreicht einen Gesamtschwenkbereich von ca. 165°.If the basket is moved further into the 75 ° working position (C), the restoring torque of the torsion bars (5) remains approximately constant, since the lever arm of the pivot bearing decreases with respect to the articulation axis (1) of the basket (2) while increasing the restoring force of the Torsion bars (5). Here, the pivot bearing (6) describes a narrower circular arc and moves axially on the torsion bar. The basket (2) reaches a total swivel range of approx. 165 °.

Obgleich der in Fig. 1 gezeigte Rettungskorb (2) in der halbhängenden Ausführungsform gezeigt ist, kann die Anlenk­achse auch höher oder tiefer bezüglich des Korbes gelegen sein. Bei einer tiefergelegenen Anlenkachse ergibt sich die sog. stehende Korbausführung. Zwar wird dann der Ein­stieg über dem Fahrzeug erschwert, dafür verringert sich aber die Fahrzeuggesamtlänge, da der Korb über den Leiter­satz geklappt werden kann.Although the rescue cage (2) shown in Fig. 1 is shown in the semi-hanging embodiment, the articulation axis can also be located higher or lower with respect to the basket. With a lower pivot axis, the so-called standing basket design results. Access to the vehicle is then made more difficult, but the overall vehicle length is reduced because the basket can be folded over the ladder set.

Die Erfindung ist vielfach anwendbar, beispielsweise bei Hubsteigern oder Teleskop-Arbeitsbühnen.The invention can be used in many ways, for example on elevators or telescopic work platforms.

Alle in der Beschreibung erwähnten und/oder in der Zeich­nung dargestellten neuen Merkmale allein oder in sinnvol­ler Kombination sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All new features mentioned in the description and / or shown in the drawing, alone or in a meaningful combination, are essential to the invention, even if they are not expressly claimed in the claims.
