Description

Støttearrangement for en kurv til mandskabslift Opfindelsens område Support arrangement for a basket for the aerial work platform Field of the Invention

Den foreliggende opfindelse angår et støttearrangement for en kurv til mandskabslift, der omfatter en lift, som er beregnet til montering på et køretøj, hvilket støttearrangement omfatter en kurveunderstøtning, hvorpå kurven er monteret, et støtteprofil, hvorpå kurveunderstøtningen er monteret, en rotator samt en konsol, hvorpå støtteprofilet er monteret, hvorhos konsollen er monteret på liftens yderste bom. The present invention relates to a support arrangement for a basket for aerial work platform, comprising a lift, which is intended to be mounted on a vehicle, which support arrangement comprises a cam support on which the basket is mounted, a support profile in which curve the support is mounted, a rotator and a bracket in which the supporting member is mounted, wherein the bracket is mounted on the hitch outermost boom.

Opfindelsens baggrund background of the invention

En mandskabslift bruges tit ved mindre vedligeholdsarbejder, hvor det ikke kan svare sig at opstille et stillads, og hvor det ikke er forsvarligt at bruge en stige. An aerial work platform used often for minor maintenance work where it is not viable to set up a scaffold and where it is not safe to use a ladder.

Lifte bygges på mange forskellige måder. Lifts are built in many different ways.

Mandskabslifte kan være af forskellig type, såsom sakselifte, tåmlifte, teleskoplifte og mobillifte. Access platforms may be of various types, such as scissor lifts, tåmlifte, telescopic aerial platforms and mobile platforms. Mandskabslifte er typisk monteret på kompakte, lette køretøjer, som er i stand til at nå de steder, hvor andre liftkøretøjer er for store og tunge til at kunne komme til. Crew Lifts are typically mounted on compact, lightweight vehicles that are able to reach places where other lift vehicles are too big and heavy to get to. Nærværende opfindelse er udviklet i forbindelse med mobillifte. The present invention has been developed in the context of mobile platforms.

Mobillifte er en lift med en kurv til 1-3 personer, der skal udføre arbejde i højden. Mobile Platforms is a lift with a basket for 1-3 persons who will carry out work at height. Liften er monteret på en lastbil, varebil, kassevogn eller en trailer. The lift is mounted on a truck, van, van or trailer. De større modeller rækker ofte 10-50 m opad. The larger models rows often 10-50 m upwards. Kurven er typisk en konstruktion med en rektangulær bund og derfra opragende støttevægge eller støtterækværk. The curve is typically a structure having a rectangular bottom and therefrom upwardly projecting support walls or support railings.

En lift, der er grundelementet i mobilliften, kan bevæge sig i tre dimensioner, hvilket gør, at køretøj sjældent skal flyttes under arbejdet. A lift that is the backbone of mobile lift can move in three dimensions, making the vehicle rarely to be moved during the work.

Liften omfatter et antal indbyrdes svingbart forbundne bomme. The lift comprises a number of mutually pivotally connected booms. En nederste bom i liften er forbundet med er krøjegear, som muliggør en rotation af liften om en lodret akse. A lower beam in the lift is connected to the Yaw gears, which enables a rotation of the hitch about a vertical axis. Krøjegear/leje er anbragt mellem pedestalen og liften. Yaw gears / bearing is disposed between the pedestal and the lift.

Kurven for personer, der skal udføre arbejde i højden, er forbundet med en yderste bom i liften. The curve for persons who are to perform work at a height, connected to an outermost beam of the lift.

Liften vil således omfatte mindst to indbyrdes svingbare bomme. The lift will thus comprise at least two mutually pivoting booms. Bommene er indbyrdes svingbare om vandret orienterede akser, således at den indbyrdes svingning af bommene etablerer en hævning og sænkning af kurven. The booms are mutually pivotable about the horizontally oriented axes, so that the mutual pivoting of the beams establishes a raising and lowering of the basket.

Den yderste bom, der i fagsprog kaldes en flyboom, er udformet som et parallelogram for at forskyde konsollen og dermed kurven med en parallelforskydning, som sikrer, at kurvens bund forbliver stort set vandret under sin bevægelse. The outer beam, which in technical language is called a flyboom, is designed as a parallelogram to displace the console and hence the basket with a parallel offset, that ensures that the bottom of the curve remains substantially horizontal during its travel. Liften kan være forsynet med sensorer eller føringer, som sikrer parallelforskydningen. The lift may be provided with sensors or guides which ensure the parallel displacement.

Bommene kan være indrettet med fast længde eller omfatte teleskopisk forskydelige bomme, som er med til at øge rækkevidden. The booms may be provided with fixed length or comprise telescoping booms, which helps to increase the range.

Bommene er konstrueret i højstyrke stål. The booms are constructed of high-strength steel. Liftens elektrohydrauliske styring kan have flere automatiserede funktioner. Lift electrohydraulic steering system may have several automated functions.

Kurven er understøttet på bommen af et støttearrangement. The basket is supported on the boom of a support arrangement. Dette omfatter en kurveunderstøtning i form af et kryds, en ramme, et H-profil eller lignende for etablering af en fastgørelse til områder nær kurvens hjørner. This includes a curve support in the form of a cross, a frame, an H-profile or the like for establishing an attachment to the areas near the corners of the basket. I det efterfølgende vil der i nærværende ansøgning med termen ''kurveunderstøtning” menes en understøtningskonstruktion, som understøtter kurven uanset formen herpå. In the following there will herein with the term '' curve support "is meant a support structure that supports the curve regardless of the shape of this. Støttearrangementet omfatter endvidere et støtteprofil, hvorpå kurveunderstøtningen er monteret, og som er forbundet med den yderste bom via en konsolenhed. Support arrangement further comprises a support profile in which curve the support is mounted and which is connected to the outer boom through a console unit.

Kurven er således forbundet med den yderste bom, så den svinges sammen med denne, og er placeret i en afstand fra den yderste bom, som er bestemt af størrelsen og formen på konsollen og støtteprofilet. The basket is thus connected to the outer boom, so that it is pivoted together with the latter, and is located at a distance from the outer beam, which is determined by the size and shape of the bracket and the support profile.

Der er ønske om at kunne dreje eller rotere kurven om en lodret rotationsakse, således at der er mulighed for at orientere kurven uafhængigt af bommenes rotation. There is the desire to be able to turn or rotate the basket about a vertical axis of rotation, so that it is possible to orient the curve, independently of the booms rotation. Dette er ønskeligt i visse arbejdssituationer. This is desirable in some work situations. For eksempel hvis et køretøj holder tæt ved og kører langs med mur eller lignende, hvor der skal udføres arbejde i højden. For example, if a vehicle is standing close by and run along the wall or the like, the work to be carried out in height. Her kan der være ønske om, at en bestemt af kurvens sider vender mod arbejdssted. Here there may be the wish that a certain of the curve sides facing workplace. Således kan støttearrangementet omfatte en såkaldt rotator, som gør det muligt for kurven at dreje til siden i forhold til den yderste bom. Thus, the support arrangement may comprise a so-called rotator, which makes it possible for the basket to pivot laterally with respect to the outer boom. AU-B-72988/94 beskriver et støttearrangement af den indledningsvis nævnte type. AU-B-72988/94 discloses a support arrangement of the initially mentioned type. Ved betjening af dette støttearrangement er der risiko for, at bruger foretager en fejlbetjening. By operating this support arrangement there is a risk that the user makes a mistake operation.

Der vil være risiko for, at kurven karambolerer med den yderste bom ved rotationen. There will be a risk that the basket with conflicts between the outermost beam by the rotation. Denne risiko er særlig udtalt, når den yderste bom er fremstillet som et parallelogram, da der i denne konstruktion er anbragt føringsstænger på hver side af et hovedprofil for at etablere parallelforskydningen. This risk is particularly pronounced when the outer boom is prepared as a parallelogram, since in this construction are arranged guide rods on either side of a head profile to establish the translation. Denne brede konstruktion begrænser muligheden for at rotere kurven. This wide structure limits the ability to rotate the basket.

Alternativt kan kurven blive monteret på en rotator, der omfatter et langt støtteprofil. Alternatively, the basket being mounted on a rotator, comprising a long support profile. Herved kan kurven svinges med en stor radius, så den går fri af den yderste bom. In this way, the basket is pivoted with a large radius, so that it is clear of the outer boom. Dette giver imidlertid en pladskrævende konstruktion, idet kurven er placeret langt fra den yderste bom. This gives, however, a bulky construction, since the basket is located far from the outermost boom.

Opfindelsens formål object of the invention

Det er formålet med den foreliggende opfindelse at afhjælpe denne ulempe og muliggøre en stor frihed til rotation af kurven i forhold til den yderste bom. The object of the present invention to overcome this disadvantage and allow a great deal of freedom for rotation of the basket with respect to the outer boom.

Ifølge et yderligere aspekt er det ønskeligt, at betjeningen af kurven sker på enkel måde uden risiko for fejlbetjening. According to a further aspect, it is desirable that the servicing of the curve takes place in a simple manner without the risk of operating errors.

Beskrivelse af opfindelsen Description of the invention

Dette opnås ifølge den foreliggende opfindelse med et støttearrangement af den indledningsvis nævnte type, som er særpræget ved, at kurveunderstøtningen er monteret forskydelig langs støtteprofilet, og at støtteprofilet er monteret på konsollen for en svingning ved rotation omkring en lodret rotationsakse, og at støttearrangementet om- fatter bevægeorganer, der er indrettet for at etablere forskydningen af kurveunderstøtningen langs støtteprofilet og svingningen af støtteprofilet i forhold til konsollen. This is achieved according to the present invention with a support arrangement of the initially mentioned type, which is peculiar in that the cam support is mounted displaceable along the support profile, and that the support profile is mounted to the bracket for pivoting by rotation about a vertical axis of rotation, and that the support arrangement conversion summarizes moving means, adapted to establish the displacement of the curve the support along the supporting member and the pivoting of the support profile relative to the bracket.

Kurven kan være placeret tæt ved den yderste bom, når den befinder sig i sin udgangsposition, og hvor det arbejde, der skal udføres, ikke giver behov for at dreje kurven. The basket can be placed close to the outer boom when it is in its initial position, and wherein the work to be carried out does not need to rotate the basket. Når der er behov for at dreje kurven i forhold til den yderste bom, så kan dette ske til en stilling, som er anbragt under en vinkel på 90° til hver side i forhold til kurvens udgangsposition. When needed to rotate the basket relative to the outer boom so that this may take place at a position which is disposed at an angle of 90 ° to each side relative to the curve starting position.

Herved kan kurvens væg - i en rektangulær kurv - længst væk fra den yderste bom blive anbragt parallelt med det plan, hvor liftens bomme svinger. This allows the basket wall - in a rectangular basket - furthest from the outermost boom being arranged parallel to the plane of the lift booms fluctuates. Dette kan ske uden risiko for, at kurven karambolerer med den yderste bom. This can be done without the risk of conflicts between the curve with the tip beam.

Forskydningen af kurveunderstøtningen etablerer en afstand mellem kurvens væg nærmest den yderste bom og den yderste bom, således at kurvens væg nærmest den yderste bom kan svinges og blive anbragt udenfor den yderste bom, selv i en situation hvor denne yderste bom har en betydelig bredde. The displacement of the curve the support establishes a distance between the cage wall closest to the outer boom and the outer boom, such that the basket wall closest to the outer boom can be pivoted and be disposed outside the outermost boom, even in a situation where the outer beam has a considerable width.

Det er muligt at variere kurveunderstøtningens og dermed kurvens forskydning langs støtteprofilet afhængigt af bredden på den yderste bom. It is possible to vary the curve of the support and thus of the curve displacement along the support profile depending on the width of the outermost boom. Derved kan kurven placeres i en ønsket afstand fra den yderste bom. In this way the curve can be placed at a desired distance from the outer boom.

Ifølge en udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at bevægeorganerne er indrettet for at etablere en samtidig forskydning af kurveunderstøtningen langs støtteprofilet og svingningen af støtteprofilet i forhold til konsollen. According to one embodiment, the support arrangement of the invention is peculiar in that the moving means is adapted to establish a simultaneous displacement of the curve the support along the supporting member and the pivoting of the support profile relative to the bracket.

Herved er der etableret en teknisk enkel og effektiv løsning, hvor det er muligt for en operatør at aktivere bevægeorganerne og derved opnå en sikker svingning af kurven uden behov for, at en operatør skal koordinere individuelle bevægelser i form af forskydningen og svingningen. In this way there is established a technically simple and effective solution where it is possible for an operator to activate the moving means and thereby achieve a secure oscillation of the curve without the need for an operator to coordinate movements of the individual in the form of the displacement and pivoting. Herved undgås risiko for fejlbetjening. This avoids the risk of user error.

Ifølge en yderligere udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at bevægeorganeme omfatter en første tandkrans, der er fast forbundet med støtteprofilet, en samvirkende anden tandkrans, der er monteret roterbart i et leje i konsollen, og som i afstand fra sin rotationsakse via en rotationsforbindelse er forbundet med en ledarm, der er forbundet med kurveunderstøtningen. According to a further embodiment, the support arrangement of the invention is peculiar in that bevægeorganeme comprises a first toothed rim, which is fixedly connected to the supporting member, a mating second toothed wheel which is mounted rotatably in a bearing in the console and which at a distance from its axis of rotation via a rotary connection is connected to a link arm, which is connected to the support curve.

Idet ledarmen er forbundet med den anden tandkrans i en afstand fra dennes rotationsakse, vil en rotation forårsage en forskydning af kurveunderstøtning og dermed også kurven, samtidig med at indgrebet mellem de to tandkranse fremkalder en svingning af støtteprofilet og dermed også kurven. As the link arm is connected to the second toothed wheel at a distance from its rotation axis, a rotation cause a displacement of the curved support, and thus also the basket, while the engagement between the two gear rims causes a pivoting of the supporting member and thus also the curve.

Rotationsforbindelsen mellem den anden tandkrans og ledarmen vil betyde, at kurveunderstøtningen kan forskydes langs støtteprofilet. The rotary connection between the second toothed wheel and the link arm will mean that the curve the support is displaceable along the support profile. Rotationsforbindelsen kan være etableret ved hjælp af en tap og en bøsning. Rotating connection can be established by means of a pin and a bush.

Ifølge en yderligere udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at den anden tandkrans omfatter en forlængelse, der strækker sig ud over tandkransens diameter, og at ledarmen er forbundet med en distal ende af forlængelsen. According to a further embodiment, the support arrangement of the invention is peculiar in that the second toothed wheel comprises an extension which extends beyond the gear ring's diameter, and that the link arm is connected to a distal end of the extension.

Med forlængelse er det muligt at øge rotationsradius for rotationsforbindelsen og dermed øges størrelsen af den forskydning, som etableres i forhold til en rotationsradius for rotationsforbindelsen, som ligger indenfor tandkransen. By extension, it is possible to increase the radius of rotation of the rotary link and thereby increase the amount of the displacement, which is established with respect to a rotational radius of the rotation of the compound which is within the ring gear. Det er således på enkel måde muligt at tilpasse en forskydning i forhold til en rotationsvinkel for kurven. Thus, it is possible in a simple manner to adapt a displacement relative to a rotation angle of the curve. Forlængelsen kan være udskiftelig eller alternativt være forsynet med flere bøsninger, som samvirker med en tap på ledarmen. The extension may be replaceable or may be provided with more sleeves which cooperate with a pin on the link arm.

Ifølge en yderligere udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at kurveunderstøtningen er forsynet med glidesko, som samvirker med støtteprofilet. According to a further embodiment, the support arrangement of the invention is peculiar in that the support baskets are provided with sliding shoes which cooperate with the supporting member.

Støtteprofilet er fremstillet af et firkantet profilrør. The support profile is made from a rectangular profile pipe. Dette kan fortrinsvis være forsynet med glideskinner, som samvirker med kurveunderstøtningens glidesko. This can preferably be provided with slide rails which co-operates with the cam of the support sliding shoes.

Herved skabes en sikker føring af forskydningen og en passende lav friktion mellem kurveunderstøtningen og støtteprofilet. This creates a secure guiding of the displacement and an appropriate low-friction curve between the support and the supporting member.

Ifølge en yderligere udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at der inden i støtteprofilet er arrangeret en aktuator, fortrinsvis en hydraulisk cylinder, som udgør en del af bevægeorganerne, idet den ved aktivering etablerer forskydningen af kurveunderstøtningen langs støtteprofilet og svingningen af støtteprofilet i forhold til konsollen. According to a further embodiment, the support arrangement according to the invention is peculiar in that within the supporting member are arranged an actuator, preferably a hydraulic cylinder, which forms part of the moving means, said by activation establishes the displacement of the curve the support along the supporting member and the pivoting of the support profile relative to the console.

Med aktuatoren arrangeret i støtteprofilet, opnås en kompakt konstruktion. With the actuator arranged in the support profile is obtained a compact construction. Der er på teknisk enkel måde etableret en beskyttelse af aktuatoren mod stød og slag. There are technically simple manner established a protection of the actuator against impact. Støtteprofilet, som er en solid konstruktion, udgør en inddækning af aktuatoren. Supporting member, which is a solid construction constitutes an enclosure of the actuator.

Ifølge en yderligere udførelsesform er støttearrangementet ifølge opfindelsen særpræget ved, at aktuatoren ved sin ene ende er monteret roterbart i forhold til støtteprofilet, og ved sin anden ende er forbundet med et svingarmsarrangement, der er monteret på den første tandkrans og på konsollen, således at en forlængelse henholdsvis en forkortelse af aktuatoren fremkalder en svingning af støtteprofilet i den ene og i den anden retning. According to a further embodiment, the support arrangement according to the invention is peculiar in that the actuator at its one end is rotatably mounted with respect to the supporting member, and at its other end is connected to a swing-arm arrangement which is mounted on the first ring gear and on the console, so that a extension respectively a shortening of the actuator causes a pivoting of the supporting member in the one and in the other direction.

Svingarmsarrangementet er arrangeret, så det svinger om en rotationsakse, der er forsat i forhold til rotationsaksen for den første tandkrans. Swing-arm arrangement is arranged so that it pivots about an axis of rotation that is offset from the axis of rotation of the first ring gear. Der er arrangeret en første svingarm, der er forbundet med aktuatoren, og en anden svingarm, der er forbundet med den første tandkrans. There are arranged a first swing arm which is connected to the actuator, and a second swing arm which is connected to the first ring gear. Forbindelsen mellem den anden svingarm og den første tandkrans er etableret ved en rotationsforbindelse, der ligeledes er forsat i forhold til rotationsaksen for den første tandkrans. The connection between the second pivoting lever and the first ring gear is established by a rotary connection, which is also offset from the axis of rotation of the first ring gear.

Rotationsforbindelsen er fortrinsvis tilvejebragt på en forlængelse ved en radius udenfor tandkransens diameter, Herved er der etableret en momentarm, så kraftbehovet for svingning af kurven kan holdes lavt. The rotation connection is preferably provided on an extension at a radius outside the gear ring's diameter Hereby is established a moment arm, so that the power requirement for the oscillation of the curve can be kept low. Forlængelsen gør det muligt at øge rotationsradius for rotationsforbindelsen og dermed mindskes størrelsen af den nødvendige kraft for etablering af svingningen. The extension makes it possible to increase the radius of rotation of the rotary connection and thus decreases the amount of force required for establishing oscillation.
