DESCRIZIONE INVENZIONE INDUSTRIALE INDUSTRIAL INVENTION DESCRIPTION
DESCRIZIONE dell' invenzione industriale dal titolo CARRELLINO MECCANICO AD AZIONAMENTO MANUALE APPLICATO AD ESTRATTORE DI FASCI TU SIERI PER LA MOVIMENTAZIONE ED IL SUPPORTO DEI FASCI. DESCRIPTION of the industrial invention entitled MECHANICAL TROLLEY WITH MANUAL OPERATION APPLIED TO A BEAM EXTRACTOR TU SERUM FOR THE HANDLING AND SUPPORT OF THE BEAMS.
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
L'invenzione del carrellino meccanico applicato ad estrattore di fasci tuberi, è nel sistema innovativo che consente non solo la movimentazione dei fasci, ma anche un loro adeguato supporto. The invention of the mechanical trolley applied to a tube bundle extractor lies in the innovative system that allows not only the handling of the bundles, but also their adequate support.
Attualmente lo stato dell'arte nella movimentazione di fasci tuberi è nell' utilizzo di carrellini meccanici muniti di N, 2 cunei laterali (uno per lato) che, scorrendo orizzontalmente sul telaio del carrellino, si avvicinano al fascio senza toccarlo. Currently the state of the art in the handling of tuber bundles is in the use of mechanical trolleys equipped with N, 2 lateral wedges (one on each side) which, sliding horizontally on the frame of the trolley, approach the bundle without touching it.
Affinchè i cunei facciano presa sul fascio, è necessario interporre tra essi ed il fascio stesso uno spessore, generalmente di materiale Legnoso, leggero e morbido, in modo che esso non venga intaccato. In alternativa, può essere utilizzato un carrellino azionato idraulicamente che favorisce il movimento e la presa del fascio tubiere ma comporta maggiori costì di realizzazione e manutenzione. In order for the wedges to grip the bundle, it is necessary to interpose between them and the bundle a thickness, generally of woody material, light and soft, so that it is not damaged. Alternatively, a hydraulically operated trolley can be used which facilitates movement and gripping of the tube bundle but entails higher construction and maintenance costs.
Dunque, il problema principale che sorge durante le operazioni dì estrazione del fascio tubiere dal mantello è supportare il fascio medesimo in modo sicuro e stabile. Mentre durante la fase di infilaggio del fascio all’interno del mantello, è necessario garantirne la giusta centratura. Therefore, the main problem that arises during the operations of extracting the tube bundle from the shell is to support the bundle in a safe and stable way. While during the phase of inserting the bundle inside the shell, it is necessary to ensure its correct centering.
Entrambe le problematiche vengono superate dall' invenzione. Both problems are overcome by the invention.
Trattasi di carrellino meccanico ad azionamento manuale munito di n. 2 cunei laterali (uno per lato), n. 2 ganasce e nd pale concave (una per lato). 1 cunei, scorrendo sul telaio del carrellino, movimentano la ganascia che solleva la pala concava Li quale, grazie alla sua particolare forma tondeggiante, si avvicina al fascio adattandosi ad esso e garantendone la presa rapida e sicura. Il movimento differenziato delle due ganasce, permette alle due pale concave di muoversi autonomamente regolando, in tal modo, la centratura del fascio tubiera cosicché Γ inserimento di quest'ultimo aLi'intemo del mantello risulta particolarmente agevole, in alternativa al carrellino meccanico, come sopra descritto, le operazioni di presa e centraggio del fascio possono essere eseguite con l'ausilio di un carrellino azionato idraulicamente. Ma ciò comporta maggiori costi dovuti all'impiego di componenti idraulici (tubi, cavi, avvolgi tubi, e così via) nonché a manutenzione straordinaria più elevata. This is a manually operated mechanical trolley equipped with n. 2 lateral wedges (one on each side), n. 2 jaws and concave blades (one on each side). The wedges, sliding on the frame of the trolley, move the jaw that raises the concave blade Li which, thanks to its particular rounded shape, approaches the bundle adapting to it and ensuring its quick and safe grip. The differentiated movement of the two jaws allows the two concave blades to move independently, thus adjusting the centering of the tube bundle so that insertion of the latter inside the shell is particularly easy, as an alternative to the mechanical trolley, as above described, the operations of gripping and centering the bundle can be performed with the aid of a hydraulically operated trolley. But this entails higher costs due to the use of hydraulic components (pipes, cables, hose reels, and so on) as well as higher extraordinary maintenance.
L'invenzione consiste nella rotazione manuale della manovella laterale al carrello, Part n,5 vedi TAV. 1. The invention consists in the manual rotation of the handle on the side of the trolley, Part n, 5 see TAV. 1.
La rotazione della suddetta manovella aziona La vite posta all'interno del telaio del carrellino, Part. n.fi vedi TAV. 1. The rotation of the aforesaid crank activates the screw placed inside the frame of the trolley, Part. n.fi see TAB. 1.
La vite, ruotando, favorisce l'avanzamento dei cuneo, Part, n.7 vedi TAV, 1. The screw, by rotating, favors the advancement of the wedge, Part, n.7 see TAV, 1.
Il cuneo solleva la ganascia, Part. n„ 8 vedi TAV.1 mediante n, 2 rulli posti al di sotto della guida della ganascia. The wedge raises the jaw, Part. n „8 see TAV.1 by means of n, 2 rollers placed under the guide of the jaw.
11 movimento della ganascia favorisce il sollevamento delle pale concave intorno all'asse di rotazione A, vedi TAV. 1, Tali pale presentano una forma tondeggiante che consente loro di modellarsi intorno al lascio tubiero, garantendone una presa ampiamente solida ed equilibrata, vedi TAV. 2. The movement of the jaw favors the lifting of the concave blades around the axis of rotation A, see TAV. 1, These blades have a rounded shape that allows them to mold themselves around the tube, ensuring a largely solid and balanced grip, see TAV. 2.
L'adattamento delle pale al fascio è consentito dalla loro rotazione rispetto all'asse B, vedi TAV. 1. The adaptation of the blades to the beam is allowed by their rotation with respect to axis B, see TAV. 1.
