DESCRIZIONE DESCRIPTION
L invenzione riguarda?una gru gir?voli secondo il concetto generale della rivendicazione principale?. The invention relates to "a slewing crane according to the general concept of the main claim".
nelle -gru ad inclinazione variabile note, la fune proveniente dal cilindro per fune portante I guidata sopra una puleggia di rinvio o galoppino che si trova coassiale alle pulegge di rinvio del boz? zello per la fune portante. Si conoscono forme di e seduzione P nelle quali il verricello di carico stesi so si trova all1interno della terre girevole. Ci? ha come,conseguenza una torre girevole di un diametro relativamente grande. E* anche noto fissare il verricello per la fune portantes sul lato di fronte al braccio,, alla torre girevole. Ci? ha come conseguenza una grande costruzione aggiunta sulla torre g?revo!es par cui il raggio di disturbo di essa vie ne notevolmente aumentato. Si conoscono anche forme di esecuzione, nelle quali il verricello per la fune portante non ? disposto all5estremit? inferiore della torre girevole,,ma alla sua estremit? super?c re e quindi coassiale alle carrucole c rulli per la fune portante. (Dubbel,, Taschenbuch fur den Maschinenbau 13. Edizione I970r pag. 599). in known variable inclination cranes, the rope coming from the cylinder for supporting rope I guided over a return pulley or pulley which is coaxial to the return pulleys of the boz? zello for the supporting rope. Forms of and seduction P are known in which the extended loading winch is located inside the revolving earth. There? results in a relatively large diameter revolving tower. It is also known to attach the winch for the carrying rope on the side opposite the arm to the revolving tower. There? results in a large construction added on the revolving tower so that the disturbance radius of it is considerably increased. Embodiments are also known, in which the winch for the supporting rope does not? willing to the extremity? bottom of the revolving tower, but at its extremity? super? c re and therefore coaxial to the pulleys and rollers for the supporting rope. (Dubbel ,, Taschenbuch fur den Maschinenbau 13. Edition I970r p. 599).
Alla base dell?invenzione ? il compito di sviluppare la gru girevole in maniera tale che i suoi, orofili esterni almeno fino all*alt?zza della piatta forma dei verricelli siano dimensionati pi? piccoli possibile* affinch? la gru 'nella rotazione non urti contro oggetti nell'cmbito delia torre girevole* Ci? vale in particolar modo per gru girevoli* che sono montate su navi. Si intende ottenere che le gru gi revoli nelle loro dimensioni esterne siano sviluppate pi? piccole possibilee in modo che esse non urtino contro*strutture navali,, pile di eontainers ed altro. At the base of the invention? the task of developing the revolving crane in such a way that its external orophiles at least up to the height of the platform of the winches are dimensioned more? small as possible * so that? the crane 'in rotation does not collide with objects in the garment of the revolving tower * Ci? especially applies to slewing cranes * which are mounted on ships. Is it intended to ensure that the revolving cranes in their external dimensions are developed more? as small as possible so that they do not collide with * naval structures, piles of eontainers and more.
L invenzione risolve il compito posto nella gru girevole descritta nel concetto generale.della rivendicazione principale per il fatto che il verricello per la fune di sollevamento ? disposto in modo tale che il braccio sollevato pu? essere por^ tato dal verricello per la fune di sollevamento li. beramente in posizione verticale rispettivamente quasi verticalec e c?? le carrucole o rulli per la fune portante fissati alia torre girevole sono ??? stati in avanti corrispondentemente in direzione verso il braccio. Ci? significa che 115asse delle pulegge di rinvio psr la fune portante non si trova coassialmente alla puleggia di rinvio per la fu ne portante che si svolge dal verr?celloe rispetti^ vamsnte non coassialmente all9asse del verricello stesso. La costruzione secondo X5lttv?*izione presen ta il vantaggi' di dimensioni esterne piccole nella sezione deila gru girevole. La gru girevole necossi t? psr ieerieatamento soltanto di VJBC spazio laterale ridotto? Perci? la gra girevole secondo 1 *invenzione^in partisolare nell1utilizzazione su na vi^ha il vantaggio c?.e pu? essere sistemata in vicinanza di strutture navali, pile di ccntainers o simile? La necessit? di spazio della gru girevole in senso orizzontale ? ridotta. The invention solves the task set in the slewing crane described in the general concept. Of the main claim in that the hoist rope winch? arranged in such a way that the raised arm can? be carried by the winch by the lifting rope. in a vertical position, respectively, almost vertical c and c ?? the pulleys or rollers for the supporting rope fixed to the revolving tower are ??? been forward correspondingly in the direction towards the arm. There? it means that the axis of the return pulleys psr the supporting rope is not coaxially with the return pulley for the load bearing funnel which unwinds from the winch and respects not coaxially to the axis of the winch itself. The construction according to X5lttv? * Ition has the advantage of small external dimensions in the section of the slewing crane. The rotating crane necossi t? psr iereatment of VJBC only reduced side space? So? the rotary table according to the invention, in particular in the use on na, has the advantage that it can be used. be placed in the vicinity of naval structures, piles of ccntainers or similar? The necessity? of space of the horizontally swiveling crane? reduced.
Secondo un ulteriore sviluppo dell3invenzione le carrucole per la fune portante possono essere ?i sposte-simmetrie amente su due organi di sopporto fis sati all5estremit? superiore della torre girevole i quali fra loro presentano una distanza tale che il braccio - sviluppato preferibilmente cerne braccio rientrante - pu? essere tirato in dentro liberamente nella sua posizione finale superiore tra le due carrucole per la fune portante. L'impiego?di un brac ci? rientrante ? vantaggioso per pi? ragioni. Un braccio rientrante pu? essere fabbricato pi? facilmente e con meno giunti saldati rispetto ad altri bracci, Bsso richiede meno materiale di quanto ? necessario per altri bracci? Un braccio rientrante pu? essere sviluppato-in struttura scatolare, la scatola rastremandosi ir.direzione verso la punta. According to a further development of the invention, the pulleys for the supporting rope can be displaced symmetrically on two support members fixed at the end. upper part of the revolving tower which have a distance between them that the arm - preferably developed as a retractable arm - can be pulled in freely to its upper end position between the two pulleys for the carrier rope. The use? Of a brac ci? re-entrant? advantageous for more? reasons. A retracting arm can? be manufactured more? easily and with fewer welded joints than other arms, Bsso requires less material than what? necessary for other arms? A retracting arm can? be developed-in box-like structure, the box tapering in direction towards the tip.
