Description

one

A device is known for transferring cargo between ships on the go, comprising a carrier cable, one end of which is wound onto a winch with the next drive on a transferring vessel, and the other side is fixed on the receiving vessel. In this case, the winch with the following drive provides a constant amount of tension of the carrying rope. A cargo trolley is hung on the carrying rope, the non-movement of which along the carrying rope is provided by a haul rope, the ends of which are attached to the drums of the haul winch or winches.

However, in the known device for installation of the cableway, at least two ropes are necessary, each of which is serviced by separate winches with a tracking drive and a complex control system. For the transfer of cargo through the carrying rope, a cargo trolley is used, which is connected simultaneously with both the carrying and the hauling ropes, which complicates the technique of receiving and transmitting cargo. The known device does not allow traversing the transfer of cargo between a vessel of a large displacement and a small vessel, since in this case, at sea, there is a risk of lifting the small vessel.

The purpose of the invention is to simplify the design of the device, reduce its cost and improve the safety of the ropeway operation.

This is achieved by the fact that in the proposed device the only working cable in the device is wound with one end on the winch drum installed on the previous vessel, and the other end is built through the cable stopper and block system on the receiver, which is connected to a hydrodynamic hydrodynamic vessel.

resistance, which creates the necessary tension of the rope. The transferred load is not attached to the working rope and moves with it, depending on the rotation of the winch drum.

Pa figs. 1 shows a diagram of the device when vessels move along a parallel course; in fig. 2 - the same, with the movement of ships in the wake.

The device consists of a working rope 1

with hydrodynamic resistance 2, block 3 and cable stonor 4 attached to one of the receiving vessels, as well as the comparator 5 dynamically. loads and winches 6 on the transmitting vessel. TO

to the working rope 1 by any known method the cargo suspension 7 is rigidly attached. The compensator 5 is made in the form of a nolisiast OR a hydrocylic hydroxide with a block.

G | pdrodinamicheskoi soirovolenis 2 represents the body of the body being towed in the underwater state, a measure of the hydrodynamic wing or wing system, which provides a constant tension of the working rope 1 necessary for (supporting the suspended load).

The device works as follows.

When transferring cargo in the traverse way, the vessels, with an IDE parallel course, 1blindle down to the required distance and equalize their speed. The end of the working rope 1 supplied from the (transferring vessel) is passed through 1ka (natal stolor 4 and block 3, after which, holding the rope 1 (stopper 4, hydrodynamic resistance 2 is attached to the free rope rope). Then, when the cable stopper 4 is clamped, the hydrodynamic resistance is lowered 2 overboard 1P is given to return to rope 1. Since, at the beginning of the device’s installation, the section (rope 1 between the ships sags, this slack is removed, the rope is etched through the cable iCTonop 4, and then, fully EO, releasing the cable stop 4, continue e Kanata 1 winch 6 to bring hydrodynamic resistance 2 to the working position. To the working rope 1 1I | Freight suspension 7 is fastened, the load is suspended to it and transferred by winding the anatom 1 by winch 6 At the same time, the first is the movement of the rope 1 with a load (several times smaller than the traffic circle of the ships, therefore the direction (I3 (change (of the rope with load) causes a significant change in the tension of the rope. The instantaneous dynamic stresses arising in the operating cable 1 are quenched with a compensator 5.

At the end of the process of transferring cargo, caeat 1 is selected with a winch 6 until the hydrodynamic approach of resistance 2 is approached by the receiving vessel. Rope (Stopper 4, the rope is clamped and then lifted into the hydrodynamic system (IR) 2 (NIE 2 on board, the end of the rope 1 is unhooked. When the stopper is clamped 4, winch 6 loosens the tension of the rope, creating a sag. Then release the stopper 4 completely ( choose the rope 1 (to the transmitting vessel with a winch 6.

When transferring goods between ships on the move in the wake direction, the receiving ship enters from (stern to the wake transmitting

the vessel for the required distance, both vessels equalize the speed, and then all the processes take place analogously to the one described above.
