Description

one

This invention relates to shipbuilding.

Ship cargo devices are known that contain a cargo boom located between two columns and armed with hauling ropes, toppers and cargo jacks.

The aim of the invention is the maintenance of two adjacent holds with one boom.

For this, the boom is 180 ° rotatable around its axis, and the boom and column knockouts are filled with swiveling guide heads for the ropes.

FIG. 1 shows the proposed device in two projections; in fig. 2 - turning head in two projections; in fig. 3 - scheme of rope hauling; in fig. 4 - ropes for boom rotation; in fig. 5 - the same, after turning the boom 180 °.

The cargo device consists of "olonnas" located on the sides of the vessel, a cargo swinging boom 2, polysparts of token 3 and a cargo guinea 4. The upper part of the columns is equipped with a rotary head 5 on which two guide blocks 6 are mounted.

For fastening the toggle to the rotating part of the head, the butt 7 is provided. The axial displacements of the rotary part of the head are prevented by means of the stoller lower casing 8, which is fastened with bolts to the upper casing 9. At the bottom of the column, guide blocks 10 are provided for the topennant ropes and cargo hangers guinea. The cargo boom nock is equipped with a swivel head 11, similar to a quiver head of columns, on which two swivel blocks are also mounted.

For fastening the tackle toppers on the swivel part of the head, two butts are provided 12. The ropes of cargo guineas 13 through guide blocks 14 located on both sides of the boom are sent to blocks 15, then to rotary blocks 16 of the boom head and further through blocks 6 and 10 of columns - on t bevy winches.

Ropes of topennants 17, through the guide blocks of columns 6 and 10, are also guided to the traction winches.

A hand (or mechanical) actuator 18 is provided on the boom support part to rotate the boom around its axis through 180 °. The final positions of the boom rotation in the specified range are fixed by stops, which exclude contact when weaving the pendant branches going inside the boom.

Moving the boom from side to side and changing its boom is provided by changing the lengths of the toppers with two winches. Cargo is lifted and lowered by cargo jacks also with the help of two winches. Thus, all the necessary movements of the loading device are provided by four winches, the pulling force of which is determined by the load carrying capacity of the loading device and the multiplicity of lop-off toppers and cargo guinea.

The service of one cargo boom of two adjacent holds is achieved by ensuring that the transfer boom rotates in the center plane of the vessel, one of them, the trumpet move on the other, and the boom rotates around its axis 180 ° 1 in a vertical position.

When selecting the ropes of both toppers, the boom is placed in a vertical position between the columns. In this position, with the aid of a pivoting device located on the boom support, the latter is rotated through an angle of 180 °. At the same time, cargo trucks move to the opposite side, shifting the center of gravity of the boom IB to the side of the boom movement. By etching the ropes of topennants, due to the resulting moment, the boom is tilted to the adjacent hold. Swivel heads of the boom and columns and swivel blocks on them provide the necessary direction of the ropes to the streams of shchivy.

Subject invention

A ship’s cargo device containing a cargo shot located between two columns and armed with traction ropes, toppers and cargo jackets, is characterized in that, in order to service two adjacent holds, one boom is 180 ° rotatable around its axis. Boom and column knuckles are made with pivoting guide heads for ropes.
