Description
Cloche de travail pour la réparation sous-marine à sec des hélices de navires. L'objet de l'invention consiste en la réalisation d'une cloche sous-marine destinée à la réparation des hélices des navires qui ont leur propulsion fixée sur les côtés des coques afin d'éviter aux bâti ments de rentrer en cale sèche ce qui permet d'obtenir un gain de temps et une économie impor tants. Work bell for dry underwater repair of ship propellers. The object of the invention consists in the production of an underwater bell intended for the repair of the propellers of ships which have their propulsion attached to the sides of the hulls in order to prevent the vessels from entering dry dock, which saves time and saves a lot of money.
Ii se caractérise par les moyens mis en ceuvre pris aussi bien dans leur ensemble que séparé ment, et plus particulièrement par une capacité pourvue à sa partie supérieure d'anneaux de manu tention et d'une porte étanche; le fond ouvert comporte sur son parement un étrier formé par un profil fixé et un collier réglable se vissant par boulons sur le tube d'étambot, alors qu'une barre d'équilibre enserre l'ogive de l'hélice; un conduit relié à la surface chasse l'eau de l'intérieur de la cloche après son positionnement fonctionnel, et une étagère réglable permet à un ou plusieurs opé rateurs de pratiquer la réparation envisagée. It is characterized by the means used taken both as a whole and separately, and more particularly by a capacity provided at its upper part with handling rings and a sealed door; the open bottom has on its facing a bracket formed by a fixed profile and an adjustable collar screwed by bolts on the stern tube, while a balance bar surrounds the ogive of the propeller; a conduit connected to the surface flushes water from the interior of the bell after its functional positioning, and an adjustable shelf allows one or more operators to perform the envisaged repair.
Sur les dessins annexés donnés à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention Les figures 1 et 2 montrent vue en coupe et de face et de profil la cloche dans son ensemble. In the accompanying drawings, given by way of non-limiting example of one of the embodiments of the object of the invention, FIGS. 1 and 2 show a sectional view, from the front and in profile, of the bell as a whole.
La figure 3 est une vue en plan par en dessous du dispositif. Figure 3 is a plan view from below of the device.
La cloche est constituée figures 1 et 2, par une capacité pourvue sur son parement supérieur d'an neaux 2 et 3 et d'une porte étanche 4. The bell is formed in Figures 1 and 2, by a capacity provided on its upper face with rings 2 and 3 and a watertight door 4.
Le fonds 5 ouvert sur ses parties 6 et 7 dégageant son entrée comporte sur sa paroi extérieure un collier réglable 8 ayant le même profil que sa contrepartie 9. Ii est positionné par les boulons 10 et 11, une barre d'équilibre 12 est également prévue. The bottom 5 open on its parts 6 and 7 clearing its entry comprises on its outer wall an adjustable collar 8 having the same profile as its counterpart 9. It is positioned by bolts 10 and 11, a balance bar 12 is also provided. .
Un tube coudé avec secteurs 13 débouchant à l'intérieur de la cloche est relié à la surface par le secteur 14. Des crochets 15 et 16 sont destinés à supporter une plate-forme de travail 17. A bent tube with sectors 13 opening inside the bell is connected to the surface by sector 14. Hooks 15 and 16 are intended to support a work platform 17.
On conçoit dès lors les avantages et les applica tions de cette cloche. The advantages and applications of this bell can therefore be seen.
La cloche est descendue par les attaches 2 et 3, la porte 4 ouverte pour être fixée sur le tube étam. bot 18 par le collier réglable 8 et 9. The bell is lowered by the clips 2 and 3, the door 4 open to be fixed on the tin tube. bot 18 by the adjustable collar 8 and 9.
La barre d'équilibre 12 réglable se place sous l'ogive 19 de l'extrémité de l'hélice. The adjustable balance bar 12 is placed under the ogive 19 of the end of the propeller.
En obturant la porte 4 et en insufflant de l'air par le conduit 14 on vide la cloche et à ce moment un plongeur sous-marin peut pénétrer à l'intérieur de la capacité, où ii peut procéder à la réparation de l'hélice 20 L'air de la cloche est renouvelé pour chasser le gaz carbonique libéré par l'occupant. By closing the door 4 and blowing air through the duct 14, the bell is emptied and at this moment a submarine diver can penetrate inside the capacity, where he can repair the propeller. 20 The air in the bell is renewed to expel the carbon dioxide released by the occupant.
Ainsi par la mise en place de l'étrier 8, 9 et la descente à l'aide d'une grue, l'ensemble peut être fonctionnellement positionné avec un minimum de manutention. Thus, by placing the stirrup 8, 9 and lowering it using a crane, the assembly can be functionally positioned with a minimum of handling.
Ii est égaiement possible d'effectuer cette mise en place en utilisant les pattes de manutention des hélices fixées à demeure sur des coques de navire. It is also possible to carry out this positioning by using the handling lugs of the propellers permanently fixed to the hulls of a ship.
Ii suffit alors de faire flotter cette cloche en fermant la porte étanche 4 et de la pousser contre la coque du navire sous les chapes de manuten tion. Un palan fixé à une chape immobilise la cloche pour permettre l'ouverture de la porte étanche, et la descente s'effectue pour coiffer l'hélice. It is then sufficient to make this bell float by closing the sealed door 4 and pushing it against the hull of the ship under the handling screeds. A hoist fixed to a yoke immobilizes the bell to allow the opening of the watertight door, and the descent takes place to cover the propeller.
Ii suffit alors de bloquer le collier 8, 9 comme indiqué figures 1 et 2. It is then sufficient to block the collar 8, 9 as indicated in Figures 1 and 2.
En tout état de cause ce dispositif présente un maximum d'effets utiles en supprimant la mise en cale sèche pour les réparations d'hélices même importantes, et permet de stabiliser la cloche de travail en l'homogénéisant au navire, ce qui empêche tout mouvement et déplacement quels que soient les courants ou remous. In any case, this device has a maximum of useful effects by eliminating the need to dry dock for even major propeller repairs, and makes it possible to stabilize the working bell by homogenizing it to the ship, which prevents any movement. and movement whatever the currents or eddies.
Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la iipite des équivalents, comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela, la conception générale de l'invention qui vient d'être décrite.However, the shapes, dimensions and arrangements of the various elements may vary within the range of equivalents, as moreover the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
