Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a ship or the like equipped with a hatch cover device.
The present invention relates to a hatch combing dustproof device for facilitating cleaning of ores and grains during cargo handling when they are scattered and accumulated on the hatch combing top.

[Conventional technology]

FIG. 3 shows a schematic view of a ship equipped with a general hatch cover device in a state where the hatch cover is opened, where 01 is a hatch cover and 02 is a hatch combing top.
FIG. 4 is a sectional view taken along line IV-IV in FIG. 3, showing a conventional hatch-combing dustproof device, in which 03 is a dustproof cover composed of a canvas sheet or a rubber sheet,
Reference numeral 03a denotes a dustproof cover 03, 04 which is in a stored state. The dustproof cover 03, 04 is installed on an upper part of the hold inner wall 07 near the hatch combing top for fixing one end of the dustproof cover 03 and fixing the other end by a string or the like in a retracted state. Shows the metal fittings.

In the above-mentioned conventional device, before starting cargo handling with the hatch cover 01 open, the dust cover 03 is operated by the operator's hand, and the other end of the dust cover 03 is connected to the metal fitting 04 from the stored state 03a. Release the lings and unfold them so that they cover the hatching combing top 02. Ore or grain that is cargo during cargo handling is dustproof cover 0
3 deposited on top. After closing the hatch cover 01 after finishing the cargo handling, the cargo accumulated on the dust cover 03 is blown off inside and outside the hatch combing by a broom or the like, and then the dust cover 03 is hung inside the hatch combing, that is, on the hold side, and the other end of the dust cover 03 is closed. Strings provided on the metal fitting 04
To the storage state 03a indicated by the dotted line.

[Problems to be solved by the invention]

By the way, in the conventional hatch-combing dust-proof device, the dust-proof cover 03 is made of a flexible sheet-like material as described above, and is difficult to handle. It was It is possible to use so-called power such as washing by spraying water on the deck other than the hatch combing top and on the closed hatch cover, but use of these power is not allowed on the hatch combing because water is not allowed to enter the hold. There is a circumstance that it cannot be done.

The present invention is intended to solve such a problem, and the ore and the like accumulated on the dust-proof cover spread on the hatch coaming top is put on the deck or in the hold by using power without manpower. It enables to be wiped off and does not require cleaning with a broom, and the work of extending the dustproof cover stored in the hold onto the hatch coaming top and moving the dustproof cover extended on the hatch combing top to the retracted state An object of the present invention is to provide a hatching combing dustproof device capable of assisting work by power.

[Means for solving problems]

Therefore, the hatch coaming dustproof device of the present invention is rooted near the upper end of the inner wall of the hatchcombing to cover the hatchcombing top at the time of cargo handling work. , It is characterized by having means for inflating and raising the dust-proof cover in which compressed gas is injected during storage work.

[Action]

According to the hatch combing dustproof device of the present invention described above, the dustproof cover is spread, cleaned and stored on the hatch combing top with the aid of the power of compressed air.

〔Example〕

Hereinafter, a hatch combing dustproof device as one embodiment of the present invention will be described with reference to the drawings.
The drawings respectively show cross-sections of hatch combing corresponding to FIG. 4 of a general hatch cover device equipped with the device of the present invention. In the figure, 12 is a hatching combing top, 13 is a dust-proof cover made of an airtight material that can be arbitrarily expanded and contracted by filling and removing air, and 14 is the dust-cover 13 attracted or not shown. A rope attached to the top of the dustproof cover 13 to secure it to the metal fittings on the outside of the hatch coaming, and a rooting metal fitting 15 attached to the hold inner wall 17 near the hatching combing top 12 to fix the dustproof cover 13 to the root. Is the dustproof cover 13
Is a guide which is supported by the air when it is inflated and stands along the inner wall of the combing and is adjusted so as to keep the center of gravity toward the inner side and is attached to the upper part of the inner wall of the hold to inflate and rise. Dustproof cover 13 in FIG.
Is in a retracted state, and when compressed air is press-fitted into it, it expands and becomes as indicated by 13a by the action of the guide metal member 16.
At this time, since the worker is located at the position indicated by the rope 14a, the worker outside the hatch coaming grasps it and holds the dustproof cover 13a.
When the rope 14a is pulled while removing the compressed air inside, the hatch combing top 12 goes through the states shown in 13b.
It is in a stretched state above. The dustproof cover 13 shown in FIG. 2 is in a state of being spread on the hatch combing top 12. In this state, dust is accumulated on the dust-proof cover 13 during the cargo handling work. When compressed air is pressed into this dust 13a
In the state shown in Fig. 5, the dust accumulated on it starts to be slid mainly inside the hatch coaming to both sides, and when the air pressure further increases, it becomes like 13b and finally the dust is covered by the dust cover 13
Everything is dropped from above. After that, the air is removed to keep the center of gravity of the dust cover 13 at the upper part of the hold, so that the dust cover 13 leans against the guide metal member 6 and enters the storage state shown by the dust cover 13 in FIG.

Although the center of gravity of the dust cover 13 inflated by injecting compressed air is inside the hatch coaming in the above embodiment, the center of gravity of the dust cover 13 is hatched by changing the position of the guide hardware 16. It is also possible to configure it so as to be on the top side, and to eliminate the need for an operator to pull the rope 14 when the cover is extended. Of course, in this case, on the contrary, a manual operation or a mechanical means for moving the center of gravity of the dustproof cover 13 to the inside of the combing when the dustproof cover 13 is stored is required.

[Effect of device]

As described above in detail, according to the hatch-combing dust-proof device of the present invention, the dust-proof cover is not a simple sheet-like one as in the conventional case but a bag-like one having airtightness, and air is injected into this. Since it can be pulled out, expanded, and contracted, the dust-proof cover can be expanded and erected during expansion or storage work to automate the work or move it to a convenient position. Also, during cleaning after loading and unloading, compressed air is blown into the dust-proof cover extended on the hatch-combing top to make the cross-sectional shape round and the dust accumulated on the dust-covered cover to both sides of the hatch-combing, that is, on the deck and in the hold. It can be slid down and automatically cleaned. Therefore, the work that conventionally required 4 workers per hatch became unnecessary for the expansion work, one for each operator of compressed air and one operator of the dust cover, and the cleaning work on the hatch combing top. Compressed air operation 1
The number of people is sufficient, and there is an advantage that labor saving can be greatly promoted.
