(54) DEVICE FOR LIFTING AND RETURNING THE ANCHOR

one

FIELD OF THE INVENTION The invention relates to shipbuilding and relates to devices for lifting and returning the core.

A device for lifting and returning a bark is known, which contains a displacer with a cable provided with a stopper and a displacer that is perpendicular to the ends of the displacer; Portal Move 1.

The disadvantage of this device is the low efficiency of work on the removal of the vessel from the vessel, since. at the moment the buoy is caught, its trap is in the dead zone for the boatmaster.

The purpose of the invention is to increase the efficiency of work on the removal of the vessel from the vessel by improving the view when removing the displacer.

The goal is achieved by the fact that the side racks of the portal and its drive are installed in a longitudinal slot made in the bow of the ship hull, the portal drive being designed as power hydraulic cylinders.

connecting the gantry racks with the hull of the vessel.

FIG. 1 shows a device, side view; in fig. 2 - portal with a trap in

J lowered state, plan.

The device contains a displacer 1 with a cable 2, passed through the eyelet 3, perpendicular to the supporting ends of the displacer 1. The cable 2 HMfeeT at one end is stopper 4 of fungoid shape, and at the other is measles (not shown)

0 The cable tensioning drive is an electric winch 5 with a brake, an uncoupling clutch and a cylindrical drum 6. On the surface of the drum 6 there is fixed a plug 7 of the stopper 4 in the form of a fork. The winch has a mechanism for setting the drum 6 with the gripper 7 to its original position. The gripper 7 in the initial position is set slightly lower than the stopper 4 in the displacer 1. The trap-8 displacer in the form of two converging guides is rigidly connected to the portal 9, which is installed in the longitudinal slot 10, made in the bow of the hull 11, with the help of hinges 12. Racks 13 of portal 9 on the outer side have

The shape of the profile of the bow of the vessel. Portal 9 is configured to move in a vertical plane at an angle of 90 °. The portal movement drive is made in the form of power hydraulic cylinders 14, which are hinged at one end to the posts 13 of the portal 9, and the other to the hull of the vessel 11. The trap 8 of the displacer has the displacer 15 stop, which prevents the displacement of the displacer 1 on the drum when the cable is selected at the moment lifting cor.

The device works as follows.

In order to lift the bass trap 8 with the portal 9 by means of hydraulic cylinders 14, it is lowered into the water to catch the displacer 1. When the catch pitch 8 is lowered into the water, the navigator opens the view through slot 10 and has the opportunity to directly observe the vessel’s approach to the displacer. After the catch of the displacer 1, the portal 9 with the trap 8 rises to the upper position. When lifting the trap, buoy 1 is in limiter 15. After lifting portal 9 to the upward position by moving the vessel forward or backward, the tension of cable 2 slows down. Since area 3 is perpendicular to the supporting ends of the displacer 1, the tension of the cable is affected. 2, the stopper 4 located on the upper end of the displacer 1 will be fixed relative to the trap 8 in a certain position, coinciding with the movement path around the circumference of the plug 7 on the drum 6. The drum 6 is turned on for rotation, and the stopper 4 is caught by the fork 7, the portal 9 is tilted In this case, the displacer 1, located in limiter 15, moves away from the drum 6. As the drum rotates further, the rope 2 moves freely in the eaver 3 of the displacer 1 and winds onto the drum b, lifting the measles. After lifting the core to the required height, the electric motor of the winch 5 is turned off and the drum b is braked. For recoil, the core turns off the disconnect coupling

and the drum b is disengaged. Measles under their own weight are lowered, unwinding cable 2. After that, the vessel moves forward or backward in a slow speed and is fully retracted. cable 2 dies from the drum b. The disconnecting clutch of the winch 5 is turned on, the portal 9 with the trap 8 is put in the extreme upper position, the drum b is turned onto the rotation, winding the cable, while the buoy 1 is pressed against the stopper 15, the stopper 4 comes out of the catch fork 7. The portal 9 with the trap 8 goes down in the lower position, the vessel, having given “reverse gear, releases the trap 2 from the displacer 1.

The use of this invention will improve the efficiency of work on the removal of the vessel from the box.
