Description

[Detailed description of the invention] The present invention relates to improvements in hatch covers for cargo ships and the like.

Although there are various problems associated with the integration of hatch cover panels, it is important to use the space in the best possible way. It is also desirable to be able to operate quickly and efficiently. There is a further demand for being able to stack and unload panels with a minimum of manual operations.

Certain hatch cover panels are piled up in a collection space at one end of the opening after each horizontal movement as the hatch is opened and closed. This is intended to ensure efficient cargo loading operations. However, the mechanisms used for conventional panel operations are complex and not necessarily suitable for automatic operation.

The present invention relates to this type of hatch cover, and provides a device that can be operated automatically using a simple device. The hatch cover of the present invention includes a lift device that is disposed above the accumulation (storage) space and includes a connecting member to the first panel, and a lift device that is arranged above the accumulation (storage) space and includes a lift device that includes a connecting member for the first panel, and a lift device that is arranged above the accumulation (storage) space, and when horizontally moving the panel into or out of the accumulation space. a clutch device provided in each of the plurality of panels, which in cooperation with a guide located in the stacking space automatically engages or disengages panels already lifted for stacking via said lifting device; It consists of

The lifting device connected to the first panel preferably comprises two parallel beams having means for cooperating with the clutch device of the first panel.

Preferably, the clutch device comprises a hook member which is pivoted on the panel and is associated with the studs of the panels that are fed in one after the other, and a guide which is provided in the accumulation space and has a fixed stop that engages with the hook member.

Each hook member preferably consists of a bell crank lever, one arm of which is formed with a hook and the other arm bifurcated to cooperate with a stop of the guide.

The stopper is preferably attached to a vertical rod extending in the stacking direction, and the other arm of the hook member cooperates with the vertical O-rad to prevent the hook member from voluntarily releasing from the stopper. A projection means is provided.

The present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a half side view of the twin deck hatch cover.

The opening 10 of this hatch cover has a plurality of panels 11 to 1.
5, these panels 11-15 are free to be removed by horizontal movement into an accumulation space 16 at the end of the opening 10. The opposite side of the opening 10 is similarly covered by a removable panel. In this case, the accumulation space 16 extends into the interior of the opening 10 corresponding to the panel width. This is the first
This means that the panel 11 does not need to move horizontally. Of course, the (upper) accumulation space 16 for stacking the panels is carefully provided well outside the opening 10.

The horizontal movement of the panels 12 to 15 is achieved by a known mechanism.
This is done, for example by wire, from the panel located furthest from the collection space 16, which is equipped with a drive motor 26 for rotating a pinion cooperating with a chain or a rack.

In the embodiment shown in FIGS. 2 and 3, a forward and reverse rotation motor 19 is connected to each side of the opening 10 via a shaft 18.
A chain mechanism 17 driven by is disposed.

Endless chain 2 provided inside this mechanism 17
The zero is rotated by two fastener wheels 21 and 22, the first fastener wheel 21 being driven by the shaft 18 as described above.

Projections 23 that project vertically downward are formed on the panels 11 to 15 so as to engage between the links of the chain 20. The distance between the axes of sprocket wheels 21 and 22 is
The setting is such that the chain 20 can successively capture the panels 11 to 15 to be lifted.

The guide plate 24 has the chain 20 connected to the panels 11 to 1.
5. While moving, hold the protrusion 23 so as to mesh with the chain 20.

The hull is widened to accommodate the transfer of a shipping container 25 on top of the twin deck cover (indicated by dotted lines in Figure 1).
.

The lift device shown at 26 is generally used for stacking the panels 11 to 15, and this lift device @26 is equipped with a motor 29 that rotates two pairs of wire drums 28 and 29. 4J are provided on each long side of the opening 10.

A pair of wires 30 that move parallel to each other are rotated between pulleys 31 and 32 to form a sliding type, and are connected to a beam 33 arranged in the long side direction of the opening 10. This constitutes a connecting means with the panel 11. In order to stack the panels 11-15 in this way, the two beams 33 are HIHJed, and these beams 33 are connected to the wire drums 28 and 29, respectively. steered by.

In the embodiment shown in FIG. 1, the lift device 26 is arranged to cover a part of the opening 10 from above, but if the pulley 32 can be installed directly on the top of the panel 11, Beam 33 is not necessarily required. By the way, in order to utilize the twin deck space in the best possible way, only the beam 33 is connected to panel 1 when the hatch cover is closed.
The beam 33 is set so that it can be lifted off from the base 1 and raised. As a result, the cargo is transported to the lift device 26.
It can be placed under the panel 11.

FIG. 4 shows details of the connection between panels 14 and 15.

Panels 14 and 15 do not necessarily have to be closed in a leak-tight manner. These panels 14,15 are transported by two pairs of wheels 35 rolling on rails 36 provided along the long sides of the edging 37. As is clear from FIG.
It is provided in the recess of the top plate so that it is parallel to or parallel to 8. A guide plate 39 is fixed inside the vertical side formed by the RN 37 at a position occupied by the foil 35 when the cover is closed. These side plates 39 cooperate with the extension ends 4.degree. of the wheel axle to avoid arbitrary lifting of the panels 11-15, for example due to twisting of the hull.

Contact members 41, 42 are provided at the moving ends of the panels 11-15 to transmit horizontal pressing forces. A guide 43 and a channel 44 are provided in the vicinity of the contact members 41 and 42 to guide the water out. A groove is cut on the long side of 37.

As the panels 11-15 move in and out of the accumulation space 16, each panel 11-15 automatically engages with the other.
III12, the panels 11-15 have at least two hook portions 114 on each of their short sides
A clutch device with 5 is provided.

Each hook S member 45 is formed as a bell crank and engages in one arm 46 thereof with a stud 48 which is attached to the panels 11-15 (or beam 33) in an overlapping position in the accumulation space 16. A groove (hook) 47 is formed like this.

The second arm 49 on the opposite side of the bellcrank is bifurcated so as to cooperate with a stationary guide rod 51 with a stop 5o inside the accumulation space 16.

No. 61il-11811 shows how the hook member 45 swings from the released position. That is.

The 7-m 46 of the hook m5t145 rises from the lowermost position of the top plate of the panel 11 (see FIG. 6) and rotates to the engagement position shown in FIG. 518.

The stopper 50g; t is appropriately attached to a vertical guide rod 51 that extends upward by ms and i along the stacked panels.

The hook member 45 is provided with a protrusion 52 projecting from its side, which protrusion 52 is adapted to move alongside the rod 51 and prevent the hook member 45 from being released arbitrarily in the panel stop position. .

Since at least two hook members 45 are provided on the side surfaces of each panel 11-15, different hook members 45 and corresponding stoppers 5o must be arranged at different levels (heights). By doing this, each stopper 50 is connected to the corresponding hook member 4.
Correctly collaborate with 5. Alternatively, only one hook member 45 may be configured to engage the stop 50, in which case further rod means are provided for transmitting motion to the other hook member 45.

The first panel 11 must be moved (pull) a small distance so that the hook members 45 engage studs 48 attached to the beam 33.

The first panel 11 must then be lifted sufficiently in its suspended position for the second panel 12 to be subsequently pushed under it. The hook member 45 of the panel 12 which is then pushed in during such operation
automatically locks with the stud 48 of panel 11, and this operation is repeated for all stacks of panels 11-15.

That is, the first panel 11 is lifted, the second panel 12 is automatically connected to the first panel 11 via the hook member 45, and therefore the panels 12 to 15 that are sent in one after another are When connected to the panel immediately above it, each time it is lifted by the lift device 26 to a predetermined number - (corresponding to the panel thickness) Hijikata, and in this way all the panels 11 to 15 are moved to the accumulation space 16. They are piled up.

In order to pull out the panels 11 to 15 piled up in this way to close the hatch frontage 10, pull out the bottom panel 15.
ground and move it toward the opening 10. This movement causes the groove 47 of the hook member 45 to
8, and since the protrusion 52 of the hook member 45 separates from the guide rod 51, the hook member 4
5 automatically rotates back to the initial position shown in FIG. 6 due to the moment due to its own weight.

After that, by repeating the same operation, go to panel 14/11
Just pull them out one by one.

The lifting device 26 and the chain mechanism 17 are controlled by suitable known devices consisting of limit switches' or other types of switches. Satisfactory automatic operation is thereby achieved.

The embodiment described above is an example of the invention, and the components making up this embodiment can be rearranged and adapted in any way depending on the size of the hatch opening and the space around it as well. It can be manufactured. It goes without saying that a structure similar to the above can also be applied to a single weather cover.
