(54) DEVICE FOR TRANSFERING PEOPLE FROM SHIP

one

This invention relates to a national trgar; cnopTV,: r ::. 7: iocT: T: i For cyaine equipment, and pred.; 1-. leKo to ensure safe n; g .kl people with a high board;

OTjpOM it is installed, and various bottom1. ;; airborne boats.

A device for transferring a ship from one ship to another in the conditions of the ship is known; containing a portable farm with front and rear blocks located on it with cargo ropes through them from the track winch, on which the cab is suspended, and guide cables for the cab attached to the traverse. During the operation of the device in the guide ropes, the track w. Winch is constantly maintained tension.

However, if the weight of the sea. Co-TopbjM is supposed to perform operations on racking up by men; is not sufficient to work in the special mode, then an accident may occur when working with the device, for example, pulling out floating vessels, OosixiMy with floating vessels of a small displacement (less than 15 tons), and

It is not possible to work at the berths near the berths where there are no special equipment to fix the traverse. The absence of a nocTosiKEoro tension of the guide ropes leads to the cabin of the cabin with aboard the vessel.

The purpose of the invention is to ensure the operation of the device with small displacement craft under conditions of sea as well as on unequipped moorings.

To do this, a rod is pivotally attached to the traverse, on which a pontoon with a ballast compartment is suspended. The ballast compartment cover is attached to the bottom part of the valve shaft, and in its upper part there are cutouts that interact with spring-loaded resistors hinged on the pontoon, having protrusions abutting wedge surfaces of cams rigidly mounted on the shaft. in the cockpit.

To bring the stop. and working position directly from the pontoon, on the shaft

with cams, a handle with spring lock can be installed. In order to reduce the dynamic forces arising when working with the Pontic on the waves in the non-automatic mode of follower, the front guide ropes can be 6bJTb mounted on the shock absorbers.

To facilitate the transfer of the moored boat to the pontoon hull through the turning circle, it is advisable to fasten the hinge gangway.

On phage. 1 shows schematically the described device, side view; in fig. 2 midsection section of the pilot; in fig. 3 - ballast section with valve; in fig. 4 ™ top view on the shaft and on the drive stops.

The device installed on the deck of the vessel 1 contains a foundation 2 with a portable farm 3 and the front 4 and rear 5 blocks located on it. Through them, cargo ropes 7, on which cab 8 is suspended, and guide ropes 9 for the cab, attached to traverse 1O, extend from the following winch.

A pontoon 12 is fixed to the traverse with the help of the rod 1, floating and stable. It consists of a body 13 and two pneumatic fenders 14 located on its sides. The housing has a ballast compartment 15 with a valve 1 ° containing a rod 11 moving in the guides 17 in the vertical direction. The rod at the top has an eyelet 18 for fastening it to the traverse, and its lower part is pivotally connected to the lid 19 of the ballast compartment. Near the eye on the rod are; Cuts a into which stops 20, pivotally fixed to housing 13 and set by springs 21. The stops have lugs b against which the wedge surfaces of cams 22 fixed on a common shaft 23 rest. which rotates only at and in both extreme positions is fixed by a spring 25. At the other end of the shaft there is an actuator 26 consisting of a gear 27, a toothed rack 28, in the upper part having a guide nipple 29, which is located under the sliding pin 30 of the cab8 Front blocks 4 pivotally fortified us on a frame 31, associated by means of rods 32 with shock absorbers 33 mounted on the remote farm 3.

Pontoon from the side has a system of stops. The upper stops 34 are fixed on the pontoon rigidly, and the lower stop 35 is attached to the underwater part of the pontoon pivotally with a limited angle of rotation from the ship’s side. On the opposite side on the deck of the pontoon there is a turning circle 36, to which a similar 37 is pivotally attached, consisting of several hinged links. The last link of the gangway has a self-aligning support roller 38.

The operation of the device begins with the return of the stoppers of the remote farm 3 and dumping it into the working position, while the drums of the winch 6 are braked. Remote farm 3 carries out the cab 8 and the pontoon 12 overboard the vessel.

In the non-automatic mode, with the following winch, the pontoon is lowered into the water and slacked to the guide ropes 9. Under the action of its own weight, the lid 19 opens and the ballast compartment 15 is filled with water. After that, the slack of the guide ropes 9 is selected in a non-automatic direction and, when a certain tension is reached, the winch is automatically switched to the tracking mode. The cover of the Itf during the tension of the guide ropes is closed, and the pontoon, having a sufficient mass, creates the necessary tension in the guide ropes both on calm water and on rough seas.

The transfer of people from the deck of the ship to the pontoon is carried out with the help of a cabin in tracking mode. Small displacement boats and lifeboats moor to the pontoon, they are fed with a turning similar 37. The turning circle 36, similar 37 and supporting roller 88 allow to compensate for the relative movements of the boat and the pontoon in the sea. Before the last descent of the cab pin 30 is pushed down through the bottom of the cab. When the cab approaches the pontoon, the retractable pin moves downward the rack 28, which rotates the bristle with the Shaft 23. Together with the shaft, rotate the cams 22, releasing the lugs 20, which under the action of the springs 21 rotate and press against the rod 11.

After lifting the cabin to the opposite position, the guide ropes are loosened, causing the lid 19 to open. When the guide ropes are selected and tensioned, the rod 11 moves upwards, the stops 20 enter the notches a and fix the lid in the open position, allowing water to flow out of the ballast compartment 15. Raise is raised in a non-automatic mode, filling the pontoon and the cabs and mounting marching is performed in reverse order.

The operation of the device when the vessel is stationed at the berth, where there are no attachment points for the traverse 10, is similar to work with small boats on the roadstead. Pontoon opu

It is connected to the quay, connected by means of a gangway, the winch 6 tensioning the guide ropes to lower the cabin.
