Description

The invention relates to shipbuilding and can be used to equip ship cargo compartments, in particular, cargo compartments of multi-purpose vessels transporting bulk cargoes (grain, coal, ore, gravel, etc.).

The aim of the invention is to simplify the design.

FIG. 1, the flat contour lines show the cargo compartment with the hatch cover, one of the pairs of sections of which lies on the hull structure, and one of the sections of the second one is raised to the cargo bulkhead position (the hatch covers with full open hatch of the cargo compartment); in fig. 2 - kinematic link with sections lying on the hull structure (node I in Fig. 1); in fig. 3 - kinematic link with sections turned 180 ° one relative to the other by laying out (node II in FIG. 1); in fig. 4 - kinematic link with one of the sections rotated 90 ° to the position of the cargo bulkhead (node III in Fig. 1); in fig. 5 shows an embodiment of aprons.

According to the invention, the cargo compartment comprises a double hinged hatch cover supported on the lower deck, each flap 1 of which includes a lead 2 and a driven 3 sections, with the leading section 2 being pivotally connected to the hull structure 4 by means of hinges bis driven by a section 3 using kinematic links 6. Each kinematic link b is a lever system consisting of a hinge-connected via axis 7 to the leading section 2 of the lever 8, the free end of which is pivotally connected to the second lever 9 mounted along Rotary through the axis 10 in the butt 11, mounted on the driven section 3. At the ends of the levers 8 and 9 in the area of their articulated joint, limiting stops 12 and 13 are mounted, while the longitudinal ends 14, 15 of the lever 8 mate with the limiting stop 16 on section 2 , and the longitudinal ends 17, 18 of the lever 9 are coupled with the restrictive stop 19 on the section 2 and with the stop 20 on the butt 11 of section 3. The stops 12 and 13 are designed to limit the angle of rotation of the levers 8 and 9 relative to each other, and the stops 16, 19 and 20 to limit the angle of rotation of the levers 8 and 9 with respect to sections 2 and 3

In the area of the intersectional joint, the aprons 21 are pivotally mounted by means of the axles 22 in the butts 23 fixed to the leading section 2. The free edge aprons 21 rest on the floor of the driven section 3. In addition, the aprons 21 can be mounted on section 3 in the guides 24 with a free edge Refer to section 2. The aprons 21 are designed to close the gap between the flooring of section 2 and the lower edge of section 3, set as

cargo bulkhead to avoid leakage of bulk cargo in the gap in the combined transport of goods.

The drive for opening the hatch cover 1 is made in the form of a flexible rod 25 connected with a mechanism for changing its length, for example, a winch.

The operation of the hatch closure of the cargo compartment of the vessel is carried out as follows.

When folding sections 2 and 3 of the cargo compartment hatch cover one relative to the other by 180 ° by laying out, the bend ha 25 is fastened to section 2 in the area of the intersectional junction.

When selecting a flexible rod 25 by means of a winch, section 2 rotates upward around a hinge joint with loops 5. In this case, the longitudinal ends 14 of the lever 8 interact with the stop 16, preventing the lever 8 from rotating around the axis 7 in the opposite direction from the flooring of sections 2 and 3. The ends 18 of the lever 9 interact with the stop 19, preventing the lever 9 from rotating around the hinge with the lever 8. Section 3, turning relative to the axis 10 of the hinge joint of the lever 9 with the butt 11, separates the stop 20 with the end 17 of the lever 9 and moves 180 ° with respect to section 2, which is installed by a thrust 25 in a vertical position, laying out.

To install the driven section 3 as a cargo bulkhead at an angle of 90 ° to the leading section 2 by decking inward, the flexible ha 25 is fastened to the driven section 3 in the area of the interfacial joint. When selecting a flexible cable 25 by means of a winch, section 3 tends to turn around one of the kinematic link hinges 6 by laying the inside.

The stop 20, interacting with the end 17 of the lever 9, prevents the section 3 from turning around the axis 10. Section 3 acts through the stop 20 on the lever 9 and together with the latter rotates around the swivel of the levers 8 and 9, selecting an angular gap between the stops 12 and 13. When the lugs 12 and 13 of the levers 8 and 9 of section 3 touch, the lever 8 acts on the lever 8 and rotates 90 ° relative to section 2 around the axes 7 of the hinge joint of lever 8 with section 2, selecting the angular gap between the end face 15 and the stop 16. End face 15 lever 8 interacts with stop 16, an obstacle further movement of section 3 via kinematic link 6 with respect to section 2. At the same time, to enable section 3 to be self-locating, the swivel arm 7 axis 7 with section 2 is away from the force of gravity of section 3 from the leading section 2, creating a tilting moment in the direction of laying section 3 on the hull structure 4 even with antikren (roll of the vessel on

the board corresponding to the raised slave section), and between the flooring of section 2 and the lower edge of the flooring of section 3, there is a gap covered by aprons.

The aprons 21 with free edge rest on the floor of section 3 and when installed in the cargo bulkhead position they rotate about axes 22 fixed in butts 23 mounted on section 2, constantly closing the gap between the floor of section 2 and the lower edge of the floor of section 3, in addition If the aprons 21 are mounted in the guides 24 on section 3, with the free edge resting on the floor of section 2, then when lifting the section 3 the aprons 21, moving in the guides 24, under the action of the force of mass constantly mate with the floor of section 2, overlapping the gap between the lower edge of the deck section 3 in the raised position and decking

,

section 2, lying on the frame structure 4.

When etching the flexible yoke 25, section 3 rotates with kinematic link 6 around axis 7. With further rotation of section 3, end 14 interacts with the stop 16, preventing rotation around axis 7, and further movement of section 3 with lever 9 occurs around the axis of the joint connections of levers 8 and 9 of the kine (Latin link 6 until the section 3 is completely laid on the body structure 4.

The invention allows to simplify the design by excluding the mechanisms for driving the forced lowering of the driven section onto the hull structure from the position of the cargo bulkhead, as well as to reduce the time and reduce the laboriousness of auxiliary work when using the driven section as a cargo bulkhead.
