Description

FIELD OF THE INVENTION The invention relates to shipbuilding, in particular to devices for snapping up floating objects.

There are known devices for snapping up floating objects when they are lowered and raised from water, including a cargo block with automatic gripping, suspended on cables from a lifting device of a carrier ship, and a cargo rod with a cable guide.

These devices are not sufficiently reliable and safe when carrying out tripping operations, require manual operations of connecting the cable-conductor to the rod.

The purpose of the invention is to improve the reliability and safety of tripping operations, to eliminate manual operations of connecting the cable guide to the rod, to ensure the possibility of returning the rod with the cable guide remotely from inside the floating object or from the side of the carrier ship.

For this, the rod has two cone-shaped heads at the ends, one of which is connected to the cable-conductor, and a grip is installed on the floating object, on the axes of the covers of which the toothed sectors that engage with each other are rigidly fixed. At the free end of one of the axes, the lever is rigidly fixed, while inside the grip under the caps there is a pulley through which the line passes, with one branch placed in the grip housing between the swivel caps and connecting outside the grip with a quick-release coupling with the branch extended out of the grip, the image of a duplin, after which a branch is attached to the carrier ship for snapping a floating object, one branch is attached to the lower head of the rod, and the other serves to pull in the rod

in capture. To release the rod with a conductor cable from inside the floating object with the crew after launching, one of the axes of the covers is connected through a pair of toothed bevel gears and a roller with a flywheel installed inside the object, and for returning the rod with the guide cable from the side of the carrier ship the opening lever connected to the control cable by means of a detachable lock, for which it is provided to disconnect from the lever

recoil cable.

FIG. 1 shows a general view of the device; in fig. 2 is a section along A-A in FIG. one; in fig. 3-section along BB in FIG. 2; in fig. 4 is a section along BB in FIG. 3; in fig. 5 - view from

arrow G in FIG. one; in fig. 6 is a section along d-d in FIG. five.

The device consists of a gripper 1 mounted on a floating object 2, a double-pulley block with an automatic gripper 3, a lifting device (not shown on the drawings), and a cargo rod 5 with heads at the ends with a cable strap attached to one of its ends 6. following winch {not shown in drawings).

The gripper consists of a housing 7, rotatable on the axis x 8 covers 9, which are spring loaded 10. The axes are interconnected by the toothed sectors //. A lever 12 is mounted on one of the axles, on which the retainer 13 is located. The lever is connected to the cable 14, at the end of which there is a link 15 connected to the lock 16, which, in turn, is connected to the control cable 17 and the recoil cable 18 ( cm, figs 2, 4, 5, 6).

The other axis (see Fig. 3) is connected through a pair of bevel gears 19 and a roller 20 with a flywheel 21 inside the floating object.

A pulley 22 is installed in the gripping housing, through which a duplin 23 passes, one branch laid in the housing between the swivel caps and connected to the end of the second branch by an easily detachable connection. Duplin 23 is laid in the linemelet bay. The latch 13 is associated with a cargo rod 5 with a cable 24.

The device for snapping floating objects while launching them into water works as follows.

Before the floating object is lowered, the duplin with one branch is placed in the gripping housing between the swivel covers and connected to the second branch with a easily detachable connection. Thereafter, the donglin is laid in the linemet bay located on the deck of the floating object. The cargo rod 5 associated with the guide cable 6 is inserted into the gripper (with its lower head), after which the guide cable is pulled around the automatic winch by turning on the tracking winch. On the cargo cables 4, a double-pulley unit is lowered with an automatic grip and hooks the top head of the rod 5. The double-bar block grip adjusts to automatic recoil. Then the floating object is lowered into the water. After acquiring buoyancy by a floating object and the appearance of slack in the cargo cables, the capture of the two-pulley block is automatically retracted. Then, a two-block automatic grip unit rises along the conduit (which is under tension all the time) to the extreme upper position to prevent the floating object from striking the two-block blocks when the floating object oscillates in the wave.

After that, the slack in the cable and cable 17 is controlled through link 15, the lock 16 and the cable 14 rotate the lever 12 and opens the swivel covers. The lever 12 is locked with locking pin 13 in the extreme position when the covers are fully open. The next lex-caustic rod 5 rises to the upper position, while the cable 24 gives

the latch 13 and the covers 9 with the springs 10 are closed, ready to lift the floating object.

The above described method of returning stock without personnel on a floating object. If there is a crew on the floating object, the brush is given as follows.

After the floating object is lowered into water and the automatic grippers of the two-block block are disconnected, the cable guide 6 is weakened. Then from the inside of the object 2, by turning the flywheel 21, the roller 20 and the bevel gears 19, the gripper covers open and the load rod 5 is given away. Then the springs 10

the covers are returned to their original position. The lifting of the floating object to the ship carrier is carried out as follows. A dowel 23 is thrown out with the help of a linemet, which is fed on board the carrier vessel. One end of the liner is fixed on the lower head of the rod 5 with a quick-detachable connection, and the other end of the load rod 5 is pulled into the grip of the floating object. The cable is guided by a cable with a 6 winch,

included in the automatic tracking mode, and along it, as along a guide, a two-block unit with automatic gripping is lowered and the top head of rod 5 is hooked. Then the floating object lifts

on board the carrier ship.

For the safety of tripping, each floating object may have two grips (aft and fore) on the deck, and the tripping device in

In this case, it should have two cargo double-lever blocks with automatic grip.
