Abstract

The invention provides a fence structure of a ship, which can satisfy height conditions of handrails and can reduce the height of a carrying component. The additional part (40) can be switched between a 1 st state that rises above the placing part (31) and a 2 nd state that is arranged below the placing part (31). Therefore, when the fence structure (150) is caused to function as a base on which the hose (16) is placed, the additional section (40) can be set to the 2 nd state so as not to interfere with the hose (16) placed on the placement section (31). When the fence structure (150) functions as a handrail, the additional section (40) can be set to the 1 st state to increase the height of the entire fence structure (150). Therefore, the height condition as the armrest can be satisfied by setting the additional portion (40) to the 1 st state to increase the height of the fence structure (150).

Description

Fence structure of ship

The present application claims priority based on japanese patent application No. 2019-052537, applied on 3/20/2019. The entire contents of this Japanese application are incorporated by reference into this specification.

Technical Field

The invention relates to a fence structure of a ship.

Background

Conventionally, as a ship, a ship described in patent document 1 is known. The ship is provided with a loading manifold on deck. The loading manifold is connected to the onshore facilities via hoses to load and unload cargo. As such, vessels sometimes connect components on deck and equipment on land to each other.

Patent documents: japanese laid-open patent publication No. H08-295288

As described above, when the members on the deck are connected to the equipment on the land, the connection members are placed on and supported by the rail structure provided on the edge portion of the deck. In order to lower the position of the connecting member, it is required to lower the height of such a fence structure, and on the other hand, to secure the function of the handrail as well, it is required to satisfy the required height condition.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object thereof is to provide a fence structure for a ship, which can satisfy a height condition as a handrail and can reduce the height when a member is placed.

The present invention relates to a ship enclosure structure provided on a deck of a ship body, the ship enclosure structure including: a main body part rising upward from the deck; and an additional portion that rises further upward from the main body portion, the main body portion having a placement portion for placing a component used on the ship, the additional portion being switchable between a 1 st state that rises further upward than the placement portion and a 2 nd state that is disposed below the placement portion.

The fence structure of a ship includes a main body portion rising upward from a deck and an additional portion further rising upward from the main body portion. The main body has a mounting portion for mounting a component used on the ship. Therefore, the arrangement of the components can be reduced by setting the height of the placement portion to be as low as possible. On the other hand, the additional portion can be switched between a 1 st state in which the additional portion stands upward from the mounting portion and a 2 nd state in which the additional portion is disposed below the mounting portion. Therefore, when the fence structure is caused to function as a base on which the member is placed, the additional portion can be set to the 2 nd state so as not to interfere with the member placed on the placement portion. In addition, when the fence structure is caused to function as a handrail, the height of the entire fence structure can be increased by setting the additional portion to the 1 st state. Therefore, by increasing the height of the fence structure when the additional portion is set to the 1 st state, the height condition as the armrest can be satisfied. According to the above, the height of the handrail can be reduced while satisfying the height condition of the handrail.

The additional portion may be coupled to the main body portion, and the 1 st state and the 2 nd state may be switched in the coupled state. Thus, the height of the fence structure can be adjusted in a state where the additional portion is connected to the main body portion without detaching the additional portion or the like.

The supplemental portion may be divided in a longitudinal direction along an edge portion of the deck. Thus, when the crew member performs the switching operation between the 1 st state and the 2 nd state on the additional portion, the weight of the additional portion can be reduced for each unit to be operated.

The additional portion may have an armrest portion extending in a longitudinal direction along an edge portion of the deck, and at least a part of the armrest portion may be formed of a rope. In this case, when another member is disposed below the main body, the armrest portion at a portion corresponding to the other member is formed of a readily deformable string (instead of a hard rod-shaped member), so that the armrest portion can be prevented from catching the other member when the additional portion is set to the 2 nd state.

The component used on the vessel may be a hose connected to the loading manifold, and the mounting portion of the main body portion may be a hose bracket for mounting the hose. As stated, the height of the hose cradle relative to the loading manifold is specified. Thus, by lowering the hose bracket, the loading manifold can be lowered, so that ports into which the ship can enter can be increased.

According to the present invention, the height of the handrail can be reduced while satisfying the height condition of the handrail.

Detailed Description

Hereinafter, preferred embodiments of the fence structure for a ship according to the present invention will be described with reference to the accompanying drawings. Fig. 1 is a schematic side view showing a ship to which a fence structure according to an embodiment of the present invention is applied, and fig. 2 is a schematic plan view of the ship shown in fig. 1. Further, the vessel 100 herein is a tanker.

As shown in fig. 1 and 2, in the ship 100, an engine room 1 is provided on the stern side (left side in fig. 1 and 2) in a hull 20, and a pump room 2 is provided on the bow side (right side in fig. 1 and 2) of the engine room 1 with a partition wall 4 interposed therebetween. A plurality of cargo spaces 3 are provided on the bow side of the pump room 2 with a partition wall 5 interposed therebetween. A bow 13 is provided on the bow side in the hull 20, and the cargo space 3 is provided on the stern side of the bow 13 with a bow bulkhead 14 interposed therebetween. Further, a plurality of ballast tanks 6 for storing ballast water are provided on the cargo space 3 side of the ship 100. Further, a tank 7 different from the ballast tank 6 is provided on the stern side of the engine room 1. Further, the tank 7 may be used for storing ballast water in the same manner as the ballast tank 6, or may be used for storing a liquid other than ballast water (for example, a liquid for sterilizing seawater to generate ballast water). The tank 7 may be an empty tank without storing any liquid. A deck 10 is provided on the upper side of the hull 20. The top surfaces of the engine room 1, the pump room 2, the cargo space 3, and the bow 13 are formed of a deck 10, and as shown in fig. 1 and 2, the bottom side is formed of a bottom outer plate 11 forming an outer shell of the hull 20 and an inner bottom plate 12 provided inside the hull 20 of the bottom outer plate 11 to form a double bottom structure. The bulkhead 4 extends in the ship width direction (vertical direction in fig. 2) and extends from the bottom shell 11 to the deck 10. The bulkhead 5 is provided so as to extend in the ship width direction and extend from the inner bottom plate 12 to the deck 10.

Cargo oil such as crude oil or refined oil transported by the ship 100 is stored in the cargo space 3. By dividing the inside of the hull into two areas in the ship width direction and seven areas in the ship length direction, for example, the cargo space 3 is divided into fourteen areas in total.

A loading manifold 15 is provided on deck 10. The loading manifold 15 is a portion that is connected to equipment on land via a hose 16 (a member used on a ship, refer to fig. 4) to load and unload cargo oil. The loading manifold 15 is disposed so that the front end thereof faces the starboard side and the port side. The loading manifold 15 supplies cargo oil sucked up from the interior of the cargo space 3 to the equipment on land. Alternatively, the loading manifold 15 leads cargo from equipment on land into the cargo space 3.

Next, the fence structure 150 of the ship 100 will be described with reference to fig. 3 and 4. Fig. 3 is a side view of the fence structure 150. Fig. 4 is a schematic view showing a state of the fence structure 150 when the hose 16 is connected to the loading manifold 15.

As shown in fig. 3 and 4, the fence structure 150 is provided at the edge 10a of the deck 10 on the upper side of the hull 20. The rail structure 150 extends in a direction along the edge portion 10a of the deck 10. The fence structure 150 is provided in a range in the rim portion 10a through which the hose 16 extending from the loading manifold 15 can pass (refer to fig. 4). A normal fence 19 is provided in an area other than the fence structure 150 in the edge portion 10 a. The extending direction of the fence structure 150 is referred to as a "longitudinal direction D1". The longitudinal direction D1 corresponds to the fore-aft direction in which the hull 20 extends. The horizontal direction perpendicular to the longitudinal direction D1 is referred to as "lateral direction D2".

The fence structure 150 includes a main body portion 30 and an additional portion 40. The main body 30 is a portion rising upward from the edge portion 10a of the deck 10. The main body 30 has a mounting portion 31 for mounting components used on the ship 100. The height of the placement unit 31 from the deck 10 is fixed. The mounting portion 31 functions as a hose bracket when the hose 16 is connected to the mounting manifold 15.

The additional portion 40 is a portion that rises further upward from the main body portion 30. The additional unit 40 can be switched between a 1 st state in which it stands upward from the placement unit 31 and a 2 nd state in which it is disposed below the placement unit 31. In this way, the fence structure 150 can change the height from the deck 10 by switching between the 1 st state and the 2 nd state. The 1 st state is the state shown in fig. 3 and the state shown by the broken line in fig. 4. The 1 st state corresponds to a state in which the hose 16 is detached from the loading manifold 15 and the fence structure 150 is used as a handrail. The 2 nd state is a state indicated by a solid line in fig. 4. The 2 nd state corresponds to a state in which the mount portion 31 of the main body portion 30 is used as a hose bracket.

Next, referring to fig. 5 to 7, a detailed structure of the fence structure 150 will be described. Fig. 5 and 6 are views of the fence structure 150 as viewed from the inside of the hull toward the outside lateral direction D2. Fig. 5 shows the fencing structure 150 in state 1. Fig. 6 shows the fencing structure 150 in state 2. FIG. 7 (a) is a sectional view taken along the VIIa-VIIa line shown in FIG. 5. FIG. 7 (b) is a sectional view taken along the VIIb-VIIb line shown in FIG. 6. In addition, in order to confirm the overall structure of the fence structure 150, fig. 3 is also appropriately referred to. The main body 30 includes a placement portion 31, a pillar portion 32, and a wall portion 33.

The placement unit 31 extends in the longitudinal direction D1 at a predetermined height from the deck 10. The mounting portion 31 includes a bottom wall portion 34 and a bent portion 36. The bottom wall 34 is a plate-like member extending in the longitudinal direction D1 in parallel with the deck 10. The curved portion 36 is provided above the bottom wall portion 34, and is curved in a semicircular arc shape in cross section. The curved portion 36 is curved in an upwardly convex manner. The outer peripheral surface of the curved portion 36 forms a mounting surface 31a of the mounting portion 31. Therefore, the hose 16 (see fig. 4) is placed on the semi-cylindrical surface (i.e., the placement surface 31a) in the placement portion 31. This allows the hose 16 to be received by the curved and smooth mounting surface 31a of the mounting portion 31.

The placement portion 31 is provided so as to extend substantially over the entire region in the longitudinal direction D1 of the fence structure 150. In the longitudinal direction D1, the end 31b of the placement portion 31 in the longitudinal direction D1 and the adjacent fence 19 are separated from each other so as to form a gap. The gap between the end 31b and the rail 19 is set to a width such that a crew member cannot pass through the deck 10. A limiting plate 37 is provided at an end 31b of the mounting portion 31 (see fig. 5). The regulating plate 37 is a plate-like member extending at least upward of the mounting surface 31 a. The restricting plate 37 restricts the movement of the hose 16 (see fig. 4) placed on the placement surface 31a toward the fence 19.

The column part 32 is a part that stands upward from the deck 10 and supports the placement part 31. The support column portion 32 is provided in plurality at predetermined intervals in the longitudinal direction D1 (see fig. 3). The lower end of the post 32 is fixed to the deck 10. The upper end of the pillar portion 32 is fixed to the lower surface of the bottom wall 34 of the mounting portion 31. The pillar portion 32 is made of a steel material having an H-shaped cross section. That is, the column portion 32 includes a web portion 32a and a flange portion 32 b. The web portion 32a extends in the transverse direction D2 and extends in the up-down direction. The flange portion 32b extends in the longitudinal direction D1 at both ends of the web portion 32a in the transverse direction D2. The web portion 32a is inclined so as to face outward of the hull 20 in the lateral direction D2 as facing upward. The lower end of the flange portion 32b is expanded in the longitudinal direction D1 and connected to the deck 10 in this state. The upper end of the flange portion 32b is enlarged in the longitudinal direction D1 and connected to the lower surface of the mounting portion 31 in this state. Further, between the pillar portion 32 and the other pillar portion 32, there is a case where a lead-out portion 38 through which a rope for fastening a ship or the like passes is provided. The lead portion 38 is disposed below the mounting portion 31. The lead portion 38 has a through portion 38a for leading the rope.

Wall 33 is a member that rises upward from deck 10 below placement unit 31. The wall portion 33 functions as a cofferdam below the placement portion 31 to prevent oil from leaking from the deck 10 to the outside of the hull 20. The wall portion 33 is formed over substantially the entire region between the one fence 19 and the other fence 19 in the longitudinal direction D1 (refer to fig. 3). The wall 33 is set to a height that does not interfere with at least the additional portion 40 in the 2 nd state. The position of the wall portion 33 in the lateral direction D2 is not particularly limited, but in the present embodiment, the wall portion is provided at a position overlapping the pillar portion 32 when viewed from the longitudinal direction D1.

The additional portion 40 includes a fixed portion 41, a bracket 42, and an armrest portion 43. The additional portion 40 is connected to the main body portion 30 and is switchable between a 1 st state and a 2 nd state in the connected state. The additional portion 40 can switch between the 1 st state and the 2 nd state by rotating the bracket 42 to change the height position of the armrest portion 43. When switching between the 1 st state and the 2 nd state, the crew member can manually operate the addition unit 40 to switch between the states.

The fixing portion 41 is a member fixed to the mounting portion 31. The fixing portion 41 is a member that pivotally supports the holder 42. The fixing portion 41 is provided to protrude downward from the lower surface of the mounting portion 31. The fixing portion 41 is disposed on the inner side of the lower surface of the placement portion 31 in the lateral direction D2. The fixing portion 41 is a plate-shaped fixing piece whose thickness direction is in the longitudinal direction D1. The mounting portion 31 is provided with a plurality of fixing portions 41 at predetermined intervals in the longitudinal direction D1.

The bracket 42 is a member that is connected to the main body 30 so as to be rotatable with respect to the main body 30 and supports the armrest portion 43. As shown in fig. 7, the bracket 42 has an L-shape when viewed in the longitudinal direction D1, and has a curved portion 42a and a main body portion 42 b. In the 1 st state shown in fig. 7 (a), the bent portion 42a extends from the fixed portion 41 inward in the lateral direction D2, and the main body portion 42b extends so as to rise upward from an end portion of the bent portion 42 a. The bent portions 42a overlap the fixed portion 41 and are rotatably coupled to each other via a shaft member 44. In the 1 st state, the bent portion 42a extends further inward than the inner end of the placement portion 31 in the lateral direction D2. In the 2 nd state shown in fig. 7 (b), the bent portion 42a extends within a range in which the main body portion 42b does not interfere with the wall portion 33. In the 1 st state shown in fig. 7 (a), the main body portion 42b extends to a position higher than the upper end of the placement portion 31. As with the fixing portion 41, the placement portion 31 is provided with a plurality of brackets 42 at predetermined intervals in the longitudinal direction D1.

As shown in fig. 5, the armrest portion 43 extends in the longitudinal direction D1 and functions as an armrest of the fence structure 150. The armrest portion 43 extends in the longitudinal direction D1 between the plurality of brackets 42. The armrest portion 43 is provided so as to connect the upper end of one bracket 42 and the upper end of the other bracket 42 in the longitudinal direction D1. A part of the armrest portion 43 is formed of a rod-like member 45 extending straight in the longitudinal direction D1. In the 2 nd state, the rod 45 is supported by the inclined surface of the pillar portion 32 (see fig. 7 (b)). That is, the downward rotation of the bracket 42 is restricted to this position.

The other part of the armrest portion 43 is constituted by a rope 46 such as a chain or a rope. The string 46 is installed between one of the brackets 42 and the other bracket 42 in a flexed state. Here, the string 46 is provided between the brackets 42 at a portion corresponding to the drawn portion 38. As shown in fig. 6, when the additional portion 40 is set to the 2 nd state, the string 46 is disposed at a position close to the through portion 38a of the drawn portion 38 as viewed in the lateral direction D2. However, the string 46 is deflected downward so that it avoids the through portion 38 a.

Here, since the rope 46 constitutes a part of the armrest portion 43, the additional portion 40 is divided in the longitudinal direction. As shown in fig. 3, the additional section 40 is divided into

units

40A, 40B, 40C, 40D, and 40E. In each unit, the brackets 42 are connected to each other by a rod-like member 45. Specifically, the

units

40A and 40E are composed of two brackets 42 and a rod-shaped member 45 connecting the brackets. The

units

40B and 40C are constituted by four brackets 42 and a rod-like member 45 connecting these brackets. The unit 40D is composed of three brackets 42 and a rod-like member 45 connecting them. The

units

40A, 40B, 40C, 40D, and 40E are connected to each other by the string 46, and the brackets 42 are connected to each other. When the additional unit 40 is lifted and lowered to switch between the 1 st state and the 2 nd state, the crew can operate the

units

40A, 40B, 40C, 40D, and 40E one by one. That is, the crew member does not need to support the weight of the entire additional portion 40 when performing the lifting operation, and only needs to support the weight of one unit. When the crew member performs the raising and lowering operation of the

units

40A, 40B, 40C, 40D, and 40E, one end of the rope 46 can be temporarily detached from the bracket 42, and if the rope 46 has a sufficient length, the raising and lowering operation can be performed with the rope 46 attached to the bracket 42.

Next, the operation and effect of the fence structure 150 of the ship 100 according to the present embodiment will be described.

The fence structure 150 of the ship 100 includes a main body portion 30 rising upward from the edge portion 10a of the deck 10, and an additional portion 40 further rising upward from the main body portion 30. The main body 30 has a placement portion 31 for placing the hose 16 used on the ship 100, and the placement portion 31 is fixed in height from the deck 10. Therefore, by setting the height of the placement portion 31 to be as low as possible, the arrangement of the hose 16 can be reduced. On the other hand, the additional unit 40 can be switched between the 1 st state in which it stands upward from the placement unit 31 and the 2 nd state in which it is disposed below the placement unit 31. Therefore, when the fence structure 150 is caused to function as a base on which the hose 16 is placed, the additional portion 40 can be set to the 2 nd state so as not to interfere with the hose 16 placed on the placement portion 31. When the fence structure 150 functions as an armrest, the additional portion 40 can be set to the 2 nd state, thereby increasing the height of the entire fence structure 150. Therefore, by setting the additional portion 40 to the 1 st state to increase the height of the fence structure 150, the height condition as the armrest can be satisfied. Specifically, there is a regulation that the height of the handrail from the deck 10 must be secured to 1000 mm. In contrast, the height of the upper end of the additional portion 40 from the deck 10 in state 1 (height H1 in fig. 4) is set to 1000mm, which satisfies the above specification. As described above, the height of the hose 16 when placed can be reduced while satisfying the height condition as the armrest.

The additional portion 40 is connected to the main body portion 30, and can switch between the 1 st state and the 2 nd state in this connected state. Thus, the height of the fence structure 150 can be adjusted in a state where the additional portion 40 is coupled to the main body portion 30 without detaching the additional portion 40 or the like.

The additional portion 40 is divided in the longitudinal direction D1 along the edge portion 10a of the deck 10. Thus, when the crew member performs the switching operation between the 1 st state and the 2 nd state on the additional unit 40, the additional unit 40 can be reduced in weight for each unit to be operated.

The additional portion 40 has an armrest portion 43 extending in the longitudinal direction D1 along the edge portion 10a of the deck 10, and at least a part of the armrest portion 43 is constituted by the string 46. In this case, when other members such as the lead-out portion 38 are disposed below the main body portion 30, the armrest portion 43 at a portion corresponding to the lead-out portion 38 is formed of the easily deformable string 46 (instead of the hard rod-shaped member 45), so that the armrest portion 43 can be prevented from catching the lead-out portion 38 when the additional portion 40 is set to the 2 nd state.

The components used in the ship 100 are the hoses 16 connected to the loading manifold 15, and the mounting portions 31 of the main body 30 are hose brackets for mounting the hoses 16. As stated, the height of the hose cradle relative to the loading manifold 15 is specified. Specifically, the height H2 shown in fig. 4 needs to be secured as prescribed by 700 mm. Therefore, the mounting manifold 15 can be lowered by setting the height of the hose bracket (i.e., the mounting portion 31) low. In this case, the height from the water line to the center of the loading manifold 15 can be reduced. In some ports, the ship 100 having the loading manifold 15 at a height equal to or higher than a predetermined height from the water line may not be loaded or unloaded with oil due to the relationship with the facilities on the land, and thus may not be able to enter the port. Therefore, by setting the loading manifold 15 to be low, the ports into which the ship 100 can enter can be increased.

The present invention is not limited to the above-described embodiments.

In the fence structure, the additional portion is rotatable with respect to the main body portion so as to be capable of switching between the 1 st state and the 2 nd state. Alternatively, the additional portion may be switched between the 1 st state and the 2 nd state by other operation modes such as up-and-down sliding movement, up-and-down movement using a folding structure using a link mechanism, and the like.

The additional portion can be switched between the 1 st state and the 2 nd state while being connected to the main body portion, but the additional portion may be detached from the main body portion to be switched from the 1 st state to the 2 nd state.

The additional portion may not be divided in the longitudinal direction. That is, the armrest portion may be constituted only by the rod-like member. In the case where only the rod-shaped member is used, a part of the rod-shaped member may be detachably configured, and the additional portion may be configured to be divided into units.

In the above-described embodiment, the ship is used as a tanker ship as a particularly preferable aspect, but the present invention is also applicable to a hybrid ship capable of loading not only oil but also solid goods (bulk goods) such as ore and coal.
