Abstract

Usage: in shipbuilding. SUMMARY OF THE INVENTION: A ship device for launching and raising a ship includes two davits, cargo winches and wire rope winches. Each of the davits is made with a front and rear boom, as well as with a remote beam connected by the middle part to the upper end of the front boom, and one of its ends to the upper end of the rear boom. At the second end of the extension beam, a corresponding winch of the guide wire is installed. 1 silt

FIELD OF THE INVENTION

mechanical engineering, and more specifically - to ship devices for launching and lifting etJia autonomous vehicles

boats, boats).

There is a known construction of a launching device such as a davit, which is used to lower and raise tunnel bots, which consists of two rotary arrows fixed in columns, four-drum and winch, cargo cable wiring and indoor boom drop out wiring, kilblocks. Nosova and aft retention s; shrinking to reduce the amplitude of the continuous swinging of the craft manually.

| The disadvantage of this SPU is the possibility of operation only in conditions of creep wave due to the absence of devices restricting the longitudinal and transverse swaying of the craft during tripping operations.

Also known is the design of the launching device of gravity-oiWoro-type boats, consisting of two davits

special guiding guide winches installed on the deck of the traction double-drum winch, cushioning device, outflow blocks, bow and stern stays.

The disadvantage of this design is the large dimensions of the davits providing gravitational descent of the craft and the need to attract additional personnel (from two to four people), limiting the swaying of the craft with the help of the bow and stern hitch during trips under high waves.

The aim of the present invention is to remedy these drawbacks, namely, to increase the reliability and safety in operation.

The essence of the invention lies in the fact that each davit consists of a front and rear boom pivotally mounted on the vessel and a remote beam pivotally connected with its middle part to the front boom, and one of its ends to the rear

The arrow and the winch of the guidewire is at the free end, while the guidewire also functions as a permanent draw of the boat from the vessel, and to reduce the swing of the boat in the transverse and longitudinal directions, which eliminates the need for additional personnel.

The drawing shows a General view of the ship's device for launching and lifting the craft. -...-.

The ship’s device for launching and raising watercraft is made of Two SLIP beams consisting of a front 1 and a rear 3 boom pivotally mounted on the vessel and a remote beam 2 pivotally connected with its middle part to the front boom 1 and one of its ends to the rear boom 3 , winches of the wire-guide 4 installed on the knockout of the remote beam 2, cargo winches 5, suspension block b, automatic grab 7, wire-conductor 8, cargo wire 9 and the dumping device

.10. . ,: .. v: V ..

The device operates as follows. :

When the freight rope is etched by 9 freight winches 5, the dumping device 10 dumps the davits with the boat over the side of the vessel, while the remote unit 2 is pulled overboard by the front boom 1, the winch 4 is pulled from the side of the ship by a wire-rope 8, at the same time a warning rocking the craft in both longitudinal and transverse directions. .

To synchronize the fall of the front boom 1 are connected together by a pipe.

After landing the vehicle on the water and disconnecting the automatic grippers 7, under the influence of the tension of the wire-ropes 8 by the winches 4, the vehicle is pulled away from the side of the vessel to a safe distance. nie. The remote winches 4 behind the front boom 1 allow, at a safe distance from the side of the vessel, also to connect the wire ropes 8 to the lifted boat .. ,,;

The proposed design serves as the basis for a new draft design of launching devices for boats.

Compared with the prototype, the proposed technical solution has the following technical and economic advantage. Improved reliability and safety.

Claims (1)

operation of the hoisting device due to the installation on the night of the remote beam of the winch of the rope-conductor, which is-. It performs the functions of a permanent dragging of the craft from the vessel and at the same time limits the swing of the craft except for striking it against the side of the ship. SUMMARY OF THE INVENTION A ship device for launching and raising a boat, comprising two davits, cargo winches, wire rope winches, and automatic grippers, each of which is mounted on a corresponding wire rope with relative movement of the latter, each davit is made with a front and rear boom pivotally mounted on the vessel, and a remote beam pivotally connected with its middle part to the front boom, and one of its ends with a rear boom, so that, in order to increase the reliability and safety in operation, each of the hoists of the wire ropes is installed on a free the end of the corresponding extension beam, and each of the automatic grippers is associated with the end of the cable of the corresponding cargo winch.
