Definitions
- the invention relates to the balancing of large tonnage vessels, such as aircraft carriers and, in particular, roll balancing, that is to say in gite.
- the presence of the central locking rail means that the rollers have to be designed 19 of restricted diameter, at least in part central, to leave space for the passage of the rail positioning 30. In this way, the mass of the assembly is significantly reduced, as is the effectiveness of the system.
- the object of the invention is therefore to remedy to these disadvantages, by proposing a device balancing of a different ship.
- the adjustment means also have a fixed sheave placed on one side of the device, both mobile sheaves being controlled by a single cylinder and placed on the other side of the device, opposite the sheave fixed, with the motor means and the jack.
- the two mobile sheaves are connected to each other in an elastic manner, the cable passing around these two mobile sheaves, the motor means being made up of a winch placed between these two sheaves mobile and around the drum from which the cable.
- the two strands of the cable is fixed inversely on the winch, around which they wrap and unwind, from this done, alternately and simultaneously.
- the cylinder is preferably a cylinder hydraulic.
- the immobilization means include mainly a pair of jaws, each pair being controlled by one end of the cable, the jaws of each pair being held apart from each other by elastic means to come resting on the side rails, their opening is controlled by cable tension on these two extremities.
- the latter be constituted by lead blocks of a shape almost parallelepiped, mounted on casters rolling on the track.
- the train When, as some requirements for large tonnage vessels, the train must be enclosed in a metal box, the track, on which these moving masses roll, being formed by the lower interior surface of the box, which is installed transversely to to the center line of the ship.
- the system balancing device is installed transversely to the ship, which is symbolized by its side walls 5.
- a metal box 3 is therefore placed transversely on a deck of the ship or ceiling under a bridge.
- the internal surface 7 of the wall lower 8 of box 3 acts as a track for the mobile ground train, which is placed inside the box.
- This train includes several wagons made up each one of a mass of lead 12 mounted on casters 13, which roll on the internal surface 7 of the wall lower 8 of box 3.
- the wagons, thus formed are connected together by a hook hitch 15 placed between each lead mass 12.
- a pair of jaws 16 intended to immobilize the train in moving away and taking support on the side walls of the housing 3.
- the train is towed by a cable 2 which also controls the operation of the two pairs of jaws 16. It is rolled up, in its right part, on a fixed sheave 17 stowed to the carcass of the ship, by example on side wall 5.
- the cable 2 passes through a control assembly, comprising a winch 20 placed between two mobile sheaves 21.
- the winch 20 controls train movements by driving the cable 2 in one direction or the other.
- the two mobile sheaves 21 control the tension of the cable 2, thereby enabling the two pairs of jaws 16.
- Figure 3 shows how the cable 2, a pair of jaws 16 and the train are fixed relative to each other.
- the end of cable 2 is fixed directly to a jaw control part 22 via a shoulder 23 constituting a grip tool grip, in case the cable 2 would be broken.
- Two jaws 24 are mounted pivoting, each around a vertical axis 26, fixed relative to the lead mass 12 at the end of the train.
- a powerful spring 27 maintains permanently the two jaws 24 apart so that each of them rubs against the lateral internal wall 39 of the box.
- the lead weights 12 are attached to each other others with a towing hook 15, which can be advantageously consisting of two heads slightly ball joints 29, each inserted into a cavity coupling 30 of a lead mass 12.
- each jaw 24 can act on the lateral internal surface 28 of the lateral walls of the box, in case these are advantageously each constituted by a profile in form of I, of type IPN, and whose height corresponding to the interior height of the box in which is the train.
- IPN 35 profiles each have two concave parts, one of which corresponds to the interior lateral surface 28. This last one has three parts, a vertical part 28A and two inclined parts 28B at the top and in the bottom of I.
- each jaw 24 has three surfaces, a vertical surface 26A and two inclined surfaces 26B placed on either side of the vertical surface 26A and forming a surface outer corresponding to the lower surface concave 28 of the IPN profile 35.
- each jaw 24 has a maximum yield since an external surface 26 maximum acts on the lateral interior surface 28 of the box.
- each mass of lead 12 is parallelepiped.
- the dimensions of each lead mass 12 correspond to the dimensions of the interior volume of the box 3, delimited mainly by surfaces lower interior 7 and upper interior 34 and through the interior surfaces 28 of the IPN profiles 35.
- a maximum of the interior section of the box 3 is occupied by the lead weights 12, which is a weight gain compared to the system described in patent application FR-2 687 978 and mentioned in the paragraph of the prior art.
- the presence of a central rail, referenced 30, reduced significantly the space available for the masses mobile.
- the fixing of such a rail 30, taking into account the special characteristics of the steel of which it is constituted, poses technological problems, in particular weldability, and its reduced size induced, by the clamping forces, stress levels important.
- FIG 4 is shown in detail the cable control assembly 2.
- the last lead weight 12 equipped with a pair of jaws 16 and its support piece 22, as well as the shoulder 23, to which the first cable strand 2A is fixed. It goes around a first mobile mounted 21A sheave in horizontal translation on a first carriage translation 36A, mounted rolling on a floor of the ship.
- the second strand of cable 2B goes into under the train and comes out on the other side of this one. It passes around a second mobile sheave 21B, mounted on a second translation carriage 36B, mounted also rolling on a ship floor. Both translation carriages 36A and 36B are connected between them elastically by a first spring 38A. One of them, in this case the second carriage 38B, is itself elastically connected to the rod mobile 41 of a hydraulic cylinder 40 fixed.
- the two strands 2A and 2B are wound on the winch drum 20A, between its passage on the first mobile sheave 21A and its passage on the second mobile sheave 21B. Whatever position of the 20A winch, in relation to the two sheaves mobile 21A and 21B, this must be established so that cable 2 goes around these two mobile sheaves 21 and 21B, over a quarter of a turn, in opposition to requests due to the fixing of two strands 2A and 2B of cable 2 to the ground train of lead.
- the hydraulic cylinder is controlled by an opening valve due to lack of current, such as a three-way valve 42.
- an opening valve due to lack of current such as a three-way valve 42.
- the relaxation of the two strands 2A and 2B of the cable done by opening the valve due to lack of current, which increases the overall reliability of the system, by compared to a tensioner using an electric jack and therefore requiring the availability of power electric for the relaxation of the two strands 2A and 2B of the cable.
- the tension of cable 2 that is to say, the train is released by activation of the hydraulic cylinder 40 by actuation of valve 42.
- a hydraulic cylinder 40 allows also to reduce the mass of the control means compared to those described in the device of the Patent application 2,687,978, previously described.
- the bearing force generated by the hydraulic cylinder 80 is independent of the position of the movable rod 41 of this last and only depends on the pressure used and the cylinder piston section, which is constant.
- the indication of a pressure gauge 48 makes it possible to monitor directly the tension forces of the two strands of the cable.
- FIG. 4 is also represented, in dashed lines, a second control assembly, identical to that shown in solid lines. he this is the control assembly of a device balancing identical to that previously described and right next to it.
- the balancing device according to the invention must be used in multiple copies. It turns out indeed advantageous to have four or five devices balancing according to the invention at the front and four or five balancing devices aft of the ship. It is pointed out that such a balancing device can move ten masses of lead 12, each weighing about two tonnes. Using ten devices balancing, according to the invention, it is thus possible have two hundred tonnes of balancing on the same ship.
- each of the two strands 2A and 2B of the cable is wound on part of the peripheral surface of the winch 20.
- each end 43 of each strand 2A and 2B is fixed to the winch, for example by means of a bolt 44 and a baffle 45 wedging the end 43 of a strand of the cable.
- the surface of the periphery cylindrical of winch 20 is reserved for winding of each of the two strands 2A and 2B of the cable.
- Figure 8 shows the advantageous presence of two grooves 46 each provided to receive a strand 2A or 2B of the cable.
- the fixation of each ends 43 of the two strands 2A and 2B, at a end of the cylinder constituting the winch 20 one can consider that the throat 46 is common to the two strands 2A and 2B. Indeed, during a rotation of the winch 20, one of the two strands 2A is wound and the other 2B is or, conversely, the amount of length of groove 46 used being substantially constant. So, the unwinding of a 2A strand frees up space for their winding from the other strand 2B of the cable.
- the parallelepiped shape of the masses lead mobile 12 optimizes the volume of the tunnel formed by box 3. Thus, we gain space, and therefore weight, using such moving masses. The effectiveness of the device is therefore increased.
- each pair of jaws 22 constitutes security, in particular in the case of rupture of one of the two strands of cable 2, during a maneuvering the moving train.
- lead masses 12 mobile equipped with four casters 13, allows them to move on the wings of standard profiles 35, constituting the lateral parts of the box.
- towing hooks 15 of ball type or similar allows some freedom movement between the masses of lead 12, in particular in angle.
