DESCRIZIONE dell' Invenzione Industriale avente per TITOLO DESCRIPTION of the Industrial Invention with TITLE

SPORTELLO RIBALTABILE CALPESTABILE WALKABLE FLIP DOOR

Campo di applicazione Field of application

La presente invenzione si riferisce ad uno sportello laterale per macchine trivellatrici e movimento terra, che assolve anche da pedana di calpestio per l?operatore che deve accedere ai componenti interni della macchina. The present invention refers to a side door for drilling and earthmoving machines, which also serves as a treading platform for the operator who has to access the internal components of the machine.

Stato della tecnica State of the art

Le macchine movimento terra sono costituite da 3 parti principali: un sottocarro generalmente cingolato che permette la movimentazione ed il piazzamento della macchina, l?apparato perforante allestito a seconda del tipo di lavoro che si vuole realizzare, ed il corpo macchina che racchiude cabina, motore, serbatoi, pompe e tutto quello che ? a supporto dell?apparato perforante. I componenti siti nel corpo macchina, ad esclusione della cabina, sono racchiusi da sportelli che li proteggono da polveri, agenti atmosferici e salvaguardano la sicurezza dell?operatore offrendo una barriera fisica da quei dispositivi che potrebbero risultare fonti di pericolo (motore in temperatura, pulegge e cinghie in movimento?). Questi sportelli sono apribili dall?esterno per permettere all?operatore di raggiungere i dispositivi interni al corpo macchina quando necessario, come ad esempio per le operazioni di manutenzione. Gli sportelli classici di queste macchine sono incernierati lateralmente (come le ante degli armadi) ed una serratura con maniglia ne previene l?apertura involontaria. Inoltre, poich? il corpo macchina ? fisicamente sopra il sottocarro e quindi rialzato da terra, vengono installate al lati del corpo macchina pedane e balaustre perimetrali per consentire il passaggio ed il lavoro in sicurezza dell?operatore che opera sui componenti interni, come anche prescritto dalle normative vigenti, esempio EN 16228. Questi dispositivi di sicurezza sono quindi trasportati separatamente rispetto il macchinario e vengono installati all?inizio dell?apertura di un cantiere, per poi essere smontati a lavoro completato per non eccedere dalle dimensioni di trasporto massime consentite che altrimenti la macchina avrebbe mantenendo le pedane perimetrali montate. Earthmoving machines consist of 3 main parts: a generally tracked undercarriage which allows the movement and positioning of the machine, the drilling apparatus set up according to the type of work to be carried out, and the machine body which encloses the cabin, engine , tanks, pumps and all that ? to support the perforating apparatus. The components located in the machine body, with the exception of the cab, are enclosed by doors which protect them from dust and atmospheric agents and safeguard the operator?s safety by offering a physical barrier from those devices which could be sources of danger (engine at high temperature, pulleys and moving belts?). These doors can be opened from the outside to allow the operator to reach the devices inside the machine body when necessary, such as for maintenance operations. The classic doors of these machines are laterally hinged (like the doors of wardrobes) and a lock with handle prevents them from being opened involuntarily. Furthermore, since the car body? physically above the undercarriage and then raised off the ground, platforms and perimeter balustrades are installed on the sides of the machine body to allow the safe passage and work of the operator who works on the internal components, as also prescribed by current regulations, for example EN 16228. These safety devices are therefore transported separately from the machinery and are installed at the beginning of the opening of a construction site, to then be disassembled when the work is completed so as not to exceed the maximum permitted transport dimensions that the machine would otherwise have keeping the perimeter platforms mounted .

Presentazione dell?invenzione Presentation of the invention

Lo sportello dell?invenzione evita l?installazione e lo smontaggio delle pedane perimetrali e delle relative balaustre offrendo sia il vantaggio di non trasportare separatamente pedane e corrimani, sia un risparmio di molte ore di lavoro per rendere operativa ed in sicurezza la macchina . The door of the invention avoids the installation and disassembly of the perimeter platforms and the relative balustrades, offering both the advantage of not transporting platforms and handrails separately, and saving many hours of work to make the machine operational and safe.

Lo sportello in oggetto si apre ruotando verso il basso, fungendo quindi una volta aperto, da piano di calpestio. I corrimani e le balaustre sono installati direttamente nella parte interna dello sportello. The door in question opens by rotating downwards, thus acting once open, as a walking surface. The handrails and balustrades are installed directly on the inside of the door.

Breve descrizione del disegno Brief description of the drawing

La figura 1 mostra una vista prospettica dello sportello abbassato in cui ? possibile distinguere tutti i componenti che lo compongono: 1- pannello esterno; 2- attuatore; 3- cerniera del pannello; 4- corrimano; 5- cerniera del corrimano; 6-superficie interna calpestabile; 7- cerniera degli attuatori Figure 1 shows a perspective view of the lowered door in which ? possible to distinguish all the components that compose it: 1- external panel; 2- actuator; 3- panel hinge; 4- handrail; 5- handrail hinge; 6-internal walkable surface; 7- actuator hinge

Descrizione dettagliata Detailed description

Lo sportello che da chiuso risulta indistinguibile dai classici sportelli delle macchine movimento terra, in cui ogni costruttore ne sceglie l?estetica, ? rappresentato aperto in figura 1. Esternamente lo sportello pu? avere la forma che il costruttore preferisce, internamente la superficie presenta le caratteristiche antiscivolo di una superficie calpestabile (richiamo 6 della figura 1). La posizione delle cerniere su cui il pannello ruota per aprirsi e portarsi in orizzontale e quindi l?asse di rotazione del pannello (richiamo 3 della figura) ? una caratteristiche essenziale dell?invenzione; esse sono fissate sia sul lato inferiore dello sportello che al telaio della macchina. L?apertura avviene non come l?anta di un armadio, ma come lo sportello di un forno. Gli attuatori (richiamo 3) che consentono l?apertura e chiusura automatica dello sportello sono in questo caso dei cilindri idraulici (richiamo 2). Essi sono fissati sia al pannello che al telaio della macchina ed una volta aperto lo mantengono nella posizione orizzontale. All?estremit? della superficie calpestabile (richiamo 6) ? installato il corrimano (richiamo 4) che tramite le sue cerniere di fissaggio (richiamo 5) pu? essere eretto o meno, a seconda delle esigenze dell?operatore. La procedura di apertura ? la seguente: quando nasce la necessit? di operare nei componenti interni della macchina, vengono azionati gli attuatori, e lo sportello si porta in posizione orizzontale. L?operatore pu? quindi avvicinarsi con una scala e salire sul piano creatosi, alzare il corrimano se necessario, ed eseguire in sicurezza le operazioni di manutenzione. The door that when closed is indistinguishable from the classic doors of earthmoving machines, in which each manufacturer chooses the aesthetics, is? represented open in figure 1. Externally the door can? have the shape that the manufacturer prefers, internally the surface has the non-slip characteristics of a walkable surface (reference 6 of figure 1). The position of the hinges on which the panel rotates to open and move horizontally and therefore the rotation axis of the panel (callout 3 in the figure) ? an essential feature of the invention; they are fixed both to the underside of the door and to the machine frame. The opening takes place not like the door of a wardrobe, but like the door of an oven. The actuators (callout 3) which allow the automatic opening and closing of the door are in this case hydraulic cylinders (callout 2). They are fixed both to the panel and to the machine frame and once opened they keep it in the horizontal position. At the end of the floor area (reference 6) ? installed the handrail (callout 4) which through its fixing hinges (callout 5) can? be erected or not, depending on the needs of the operator. The opening procedure? the following: when does the need arise? to operate in the internal components of the machine, the actuators are activated, and the door moves to the horizontal position. The operator can? then approach with a ladder and climb the created level, raise the handrail if necessary, and carry out the maintenance operations in safety.

Gli sportelli in oggetto del presente brevetto costituiscono parte integrante delle cofanature esterne e delle pedane perimetrali. The doors subject of this patent form an integral part of the external casings and the perimeter platforms.

Si deve intendere che l?invenzione non ? limitata alla forma descritta in figura 1 come esempio, alcune modifiche possono essere apportate senza per questo dipartirsi dall?ambito dell?invenzione e della portata del presente brevetto, come definito nelle annesse rivendicazioni. It must be understood that the invention is not limited to the shape described in figure 1 as an example, some modifications can be made without departing from the scope of the invention and scope of the present patent, as defined in the annexed claims.
