Description

Fall protection device for ship deck manhole

Technical Field

The utility model relates to a marine facility, in particular to a falling-preventing device for a manhole of a ship deck, and belongs to the technical field of ships.

Background

The upper decks of bulk cargo ships, ore sand ships and the like and container ships, and the two decks of the multipurpose ship are provided with manhole covers which enter the liquid tanks below the decks. The height of these tanks is very high, about 6 meters. If the manhole channel is not protected after the manhole cover is opened, there may be a risk that a crew falls from the manhole channel to the bottom of the liquid cabin to be injured.

To solve this problem, the prior art generally provides protection by providing a protective fence around the manhole. The protective fence has the advantages that the protective fence is large in size and inconvenient to carry, and is required to be fixedly connected with a deck near a manhole, so that the installation operation is complex; in addition, after the protective fence is installed, part of the deck channel is shielded by the protective fence, so that the passage of a crew is inconvenient.

The utility model adopts the following technical scheme:

the anti-falling device for the deck manhole of the ship comprises a deck manhole and a manhole cover, wherein a plurality of vertical mounting holes are correspondingly distributed around the deck manhole and the manhole cover, and the manhole cover is fixed on the mounting holes through studs and nuts; the protective cover comprises a grid protective cover, wherein one side of the grid protective cover is provided with a pair of hinges; under the condition that the manhole cover is removed from the deck manhole, a pair of studs at the axisymmetric part of the deck manhole are fixedly provided with pin shafts, and the pin shafts are hinged with the hinges; the grid protective cover is overturned through the hinge and can completely cover the deck manhole.

Preferably, the deck manhole is in a waist-round hole shape.

Preferably, the grille guard is made of round steel having a diameter of 10 mm.

Preferably, a handle is arranged on the grille protection cover.

Preferably, the grid protection cover is coated with reflective paint, so that the grid protection cover can play a role in warning at night.

Preferably, the grille guard is rectangular.

The utility model has the beneficial effects that: the novel design is carried out on the ship deck manhole anti-falling device: after the manhole cover is opened, the grid protective cover is hinged to the manhole channel so as to prevent a shipman from falling to the bottom of the liquid tank from the manhole channel, and the existing studs and bolts of the manhole cover and the deck manhole are ingeniously utilized.

Detailed Description

The utility model will be further described with reference to the drawings and specific examples.

Embodiment one:

referring to fig. 1, fig. 1 shows a manhole access fall protection device for a bulk carrier, a top deck flush manhole cover of a sand carrier. A ship deck manhole anti-falling device is shown in fig. 1 (a), wherein a plurality of vertical mounting holes are correspondingly distributed around a deck manhole and a manhole cover, and the manhole cover is fixed on the mounting holes through studs and nuts;

in order to enter the space below the deck, as shown in fig. 1 (b), when the manhole cover is removed from the deck manhole, as shown in fig. 1 (a), a pair of hinges are arranged on one side of the grille protecting cover, and a pin shaft is fixedly arranged on a pair of studs at the axisymmetric part of the deck manhole and hinged with the hinges; the grid protective cover is overturned through the hinge and can completely cover the deck manhole. The grille guard can be flipped open about the hinge as shown in fig. 1 (d).

As shown in fig. 1 (a), the deck manhole has a oval hole shape.

In this embodiment, as shown in fig. 1 (b), the grill protection cover is made of round steel having a diameter of 10 mm. The round steel can keep a larger gap, and the grille protective cover can adopt different standard types according to different manhole cover specifications and sizes.

In this embodiment, the grille guard cover is provided with a pull handle. I.e. using the pin as a handle.

In this embodiment, the grille guard is painted with reflective paint to provide warning at night.

In this embodiment, the grille guard is rectangular as shown in fig. 1 (b).

When the screw bolt is specifically used, after the cover plate of the manhole cover is taken down, the screw bolt connecting the cover plate of the manhole cover and the seat plate is still on the deck. A grid cap made of round steel with a diameter of 10 as shown in the figure can be used at this time, and the stud and the nut of the original manhole cover are fixed with the hinge of the grid cap.

Embodiment two:

referring to fig. 2, fig. 2 shows a schematic view of a two deck buried manhole cover manhole access fall protection device for a container ship, a multipurpose ship. The difference from the first embodiment is that the manhole cover covers the rear upper surface flush with the deck. Referring to fig. 2, in a ship deck manhole anti-falling device, as shown in fig. 2 (a), a plurality of vertical mounting holes are correspondingly distributed around a deck manhole and a manhole cover, and the manhole cover is fixed on the mounting holes through studs and nuts;
