Description

The present invention relates to a mooring device for mooring a ship on a quay, and more particularly to a ship mooring device for preventing an unexpected drift of a ship even when the sea level rises abnormally due to the occurrence of a tsunami or the like.

Vessels that enter the port for berthing are stopped and prevented from leaving the shore by tying mooring ropes such as ropes and wire ropes to mooring columns protruding from the quay or pier. In general, berthing facilities such as quays are designed to have a height that does not hinder the boarding and alighting of passengers on ships and the handling of cargo even if the water level changes due to the rise and fall of the sea level according to the ebb and flow. Further, even when a large wave covers the quay when a spring tide and a typhoon overlap, there is no problem in mooring a ship moored by a mooring rope on the mooring column. A fender is attached to the berthing facility to prevent damage to the ship and the berthing facility.

By the way, it is fresh in my memory that in recent years, a tsunami that far exceeded expectations has occurred due to the occurrence of a large earthquake, causing great damage. When the sea level rises abnormally due to such a tsunami or the like, the vessels moored by the mooring rope on the mooring column rise as the sea level rises. If the sea level rises more than expected, the vessel may capsize.

8 and 9 show a state in which the ship S is moored by the mooring rope 22 on the mooring column 21 provided on the quay G. FIG. 8 shows normal times, and the ship S also moves up and down according to the rise and fall of the sea level L due to the ebb and flow of the tide, but the height of the quay G does not hinder getting on and off the ship S and cargo handling. Has been done. On the other hand, when the sea level L rises to a height higher than expected due to a storm or tsunami and far exceeds the height of the quay G, as shown in FIG. 9, the ship S rises to the sea level L. Ascends beyond the height of the quay G. The mooring rope 22 has a length sufficient to maintain the state in which the ship S is berthed. Therefore, when the sea level L rises abnormally, the mooring rope 22 is between the mooring column 21 and the sea level L. There is a risk that the distance between the two will be larger than the length of the mooring rope 22. In such a case, as shown in FIG. 9, the ship S may be restrained by the mooring rope 22, and the side on which the mooring rope 22 is suspended may be pulled in and capsized. In addition, the tense mooring rope 22 may break, and the ship S may be carried by the tsunami and drift, or may be carried to land and stranded.

As a ship mooring device for preventing a ship from overturning when the sea level rises abnormally, a ship mooring device for connecting a berthed ship and a bollard with a mooring rope accommodates the base of the mooring pillar to which the mooring rope is connected. A holding hole is formed in the quay, a continuous accommodating hole is formed in the retaining hole, an extension member is accommodated in the accommodating hole, the tip of the extension member is fixed to the base of the mooring column, and the extension member is fixed. The base end of the bollard is fixed to an arbitrary part, and the length of the extension material extending from the quay is made larger than the distance between the sea surface and the quay that has risen to an abnormal height. Therefore, a ship mooring device has been proposed in which a holding means for holding the base of the mooring bollard is provided in the holding hole, and when seawater invades the holding hole, the holding means is released to free the mooring pillar. (See Patent Document 1).

Japanese Unexamined Patent Publication No. 2015-382774

In the ship mooring device disclosed in Patent Document 1, since one end of the mooring rope fixed to the ship is moored to the mooring column, the mooring rope may come off from the mooring column depending on the behavior of the sea surface at the time of abnormal rise. There is a risk that the ship will drift.

Further, since the structure is adopted in which the holding means is released by the infiltration of seawater, for example, when the sea level rises abnormally such as a tsunami, the invaded seawater behaves violently and the holding means is released. May prevent it. On the other hand, to reduce the holding force by the holding means, when to be easily released by seawater intrusion, when it becomes a situation where wear waves wharf by storms such as typhoons, released inadvertently holding means There is a risk that the ship will be separated from the quay.

Therefore, the present invention prevents a ship moored on a quay from being restrained by a mooring rope and overturning when the tide level rises abnormally such as a tsunami, or the mooring rope coming off the mooring pillar and drifting as much as possible. It is intended to provide a ship mooring device capable of.

As a technical means for achieving the above object, the ship mooring device according to the present invention is a ship mooring device for connecting a berthed ship and mooring equipment with a mooring rope, and is an outer surface of a rope storage box for accommodating an extension rope. In the middle of the height of the rope storage box, an outwardly projecting portion is provided, the rope storage box is embedded in the quay, and the rope storage box is connected to the bottom plate of the extension rope. The base end is fixed, the tip of the extension rope is connected and fixed to a lid body detachably provided in the rope storage box, and the mooring rope is tied to a rope hooking member provided in the lid body. Each end of the separating member composed of the detaching side separating member and the fixed side separating member is fixed by hanging on the lid and the bottom plate, and the separating member is lifted by the load when the ship rises to an abnormal height. It is characterized in that the lid is separated and detached from the rope storage box.

When the ship rises and the mooring rope is pulled up due to the abnormal rise in sea level caused by the invasion of a tsunami or the like, a load is applied to the separating member and the separating member is separated. As a result, the detaching side separating member is detached from the fixed side separating member, and the lid is detached from the rope storage box. Since the tip of the extension rope is fixed to this lid, the extension rope is pulled out as the ship of the lid rises. Therefore, the ship is allowed to rise and the ship is regulated within the range of the length of the extension rope.
Further, even if the rope storage box embedded in the quay is to be pulled out by the ascent of the ship, the protruding portion is not easily pulled out against the tensile force.

Further, in the ship mooring device according to the invention of claim 2 , a part of the separating member is reduced in diameter to form a reduced diameter portion, and the reduced diameter portion is broken and separated by a tensile force due to the ascent of the ship. It is characterized by.

The separating member receives a tensile force due to the rising of the ship due to an abnormal rise in the sea level, and the extension rope is pulled out by breaking at the reduced diameter portion formed in a part of the separating member, so that the ship is allowed to rise. It is intended to be done.

Further, in the ship mooring device according to the invention of claim 3, the separating member is composed of a detaching side separating member on the mooring rope side and a fixed side separating member on the quay side, and these separating members and the fixed side separating member are used. Is connected by a shear pin, and the shear pin is broken by receiving a shearing force due to the ascent of the ship, and the separating member is separated.

The shear pin connecting the detaching side separating member and the fixed side separating member receives a shearing force due to the detaching side separating member being pulled up with respect to the fixed side separating member due to the ascent of the ship due to an abnormal rise in the sea level. And break. As a result, the extension rope is pulled out, and the ship is allowed to rise.

Further, in the ship mooring device according to the invention of claim 4 , one of the separating member elements of the detaching side separating member and the fixed side separating member is provided as a pair, and the other is arranged as a part of the pair of separating member elements. Then, a shear member is hung over the pair of separating member elements and the other separating member element, and the shearing member is broken by receiving a shearing force due to the ascent of the ship to separate one separating member element from the other. It is characterized in that it is separated from the member elements.

When the ship rises due to an abnormal rise in sea level, the detaching side separating member is pulled up with respect to the fixed side separating member, so that the shearing member hung on these separating member elements breaks due to the shearing force. As a result, the extension rope is pulled out, and the ship is allowed to rise.

Further, in the ship mooring device according to the invention of claim 5, the lid body is put on the top plate of the rope storage box, the detaching side separating member of the separating member is connected to the lid body, and the lid body and the top plate are connected. A water ingress blocking means is provided between the two to prevent water from entering the rope storage box, and when the detaching side separating member is separated from the fixed side separating member, the lid is separated from the top plate.

Hereinafter, the ship mooring device according to the present invention will be specifically described based on the preferred embodiment shown.

FIG. 1 shows a schematic structure of the ship mooring device 1, which is installed on the quay G, which is a berthing facility for ships. As shown in FIG. 1, a rope storage box 2 is embedded and installed in the quay G, and an extension rope 3 is housed therein. The bottom plate 2a of the rope storage box 2 is provided with a base end side connection fitting 4 whose base end portion is swingable around a shaft 4a, and the extension rope is provided at the tip end portion of the base end side connection fitting 4. The base end portion of 3 is fixed.
Further, a protruding portion 51 is provided on the outer surface of the rope storage box 2 so as to project outward. The protrusions 51 may be provided on the outer surface of the rope accommodating box 2 at appropriate intervals, or may be continuously provided as flanges on the outer surface. The protrusion 51 is arranged at a position where it is buried in the quay G.

An annular top plate 2b is covered on the upper part of the rope storage box 2, and the peripheral edge portion of the top plate 2b is dropped and fixed to the counterbore portion formed on the quay G, and the rope storage box 2 is fixed. Inundation between the outer peripheral surface and the quay G is prevented. A fitting convex portion 6a formed on the lower surface of the lid 6 is fitted inside the annular shape of the top plate 2b.

The lid 6 is composed of a support plate portion 6b to which the fitting convex portion 6a is fixed and a lid portion 6d that covers the support plate portion 6b. The support plate portion 6b is formed with a through-hole portion 6c having a sufficient size so that an operation described later can be performed, and is connected to the top plate 2b via a shear pin 7 for preventing rotation. .. The lid portion 6d is fixed to the upper surface of the support plate portion 6b by the fixing bolts 6e. Then, a U-shaped mooring column 9 as a rope hooking member of the rope fixing bracket to which the mooring rope (see FIG. 8) extending from the ship is tied is fixed to the upper surface of the lid body portion 6d. Further, a waterproof material 2c as a means for blocking water ingress is interposed between the support plate portion 6b and the top plate 2b, and seawater enters the rope storage box 2 from the gap between the top plate 2b and the support plate portion 6b. Is prevented from invading.

On the lower surface of the fitting convex portion 6a of the lid body 6, a tip-side connecting fitting 5 whose base end portion is swingable around a shaft 5a is provided, and the tip end portion of the tip-side connecting fitting 5 is provided. The tip of the extension rope 3 is fixed.

A through hole 6f is formed in the central portion of the fitting convex portion 6a, an upper end portion of the breaking rod 8 as a separating member penetrates the through hole 6f, and the upper end portion thereof is the through hole portion 6c. It is located in. A male threaded portion is formed at the upper end of the breaking rod 8, and a tightening nut 8a is screwed into the male threaded portion. Therefore, the size of the through-hole portion 6c is set so that the tightening nut 8a can be tightened to the upper end portion of the breaking rod 8. The lower end of the breaking rod 8 is fixed to the bottom plate 2a of the rope storage box 2. Then, as will be described later, the breaking rod 8 is formed with a reduced diameter portion 8b so as to break when a tensile force of a predetermined magnitude is applied. The upper side of the reduced diameter portion 8b is the detaching side separating member, and the lower side is the fixed side separating member.

In order to install the ship mooring device 1, the base end side of the extension rope 3 is fixed to the tip end portion of the base end side connection fitting 4 of the rope storage box 2 installed on the quay G. The tip end side of the extension rope 3 is fixed to the tip end portion of the tip end side connection fitting 5, and is accommodated in the rope storage box 2. While fitting the fitting convex portion 6a of the lid 6 inside the annular top plate 2b, the support plate portion so that the tip end portion of the breaking rod 8 penetrates the through hole 6f of the fitting convex portion 6a. Cover the top plate 2b with 6b. At this time, the support plate portion 6b is connected to the top plate 2b by the shear pin 7. Further, with the support plate portion 6b covering the top plate 2b, these gaps are sealed by the waterproof material 2c.

Then, when the tightening nut 8a is tightened to the male screw portion of the upper end portion of the breaking rod 8 exposed to the through hole portion 6c of the support plate portion 6b, the support plate portion 6b is brought into close contact with the top plate 2b to be waterproofed. The material 2c comes into close contact with the top plate 2b to prevent seawater from entering through the gap between the support plate portion 6b and the top plate 2b.

Next, when the lid body portion 6d is fixed to the support plate portion 6b with the fixing bolt 6e, the lid body 6 is covered with the rope storage box 2 and closed, and the U-shaped mooring column is in a state of protruding from the quay G. , This ship mooring device 1 is installed.

When a ship berths at the ship mooring device 1 installed as described above for mooring, the mooring rope extended from the ship is tied to the U-shaped bollard 9. In normal times, the sea level rises and falls within a range lower than the upper surface of the quay G even due to ebb and flow and waves, and boarding and alighting of ships and cargo handling are performed in a stable manner. Further, even when the tension related to the mooring rope changes due to the behavior of the ship, the lid 1 provided with the U-shaped mooring column 9 has shear pins 7 on the lid portion 6d and the top plate 2b. Since it is interposed, the lid 1 does not rotate with respect to the rope storage box 2. Further, even if the mooring rope is tense and the lid 1 is about to be pulled out, it is not pulled out because it is restrained by the breaking rod 8. Therefore, in normal times, the state in which the ship is moored at the quay G via the mooring rope is maintained in the same manner as a normal bollard.

When the ship rises above the quay G along with the sea surface that rises abnormally due to the tsunami, the mooring rope becomes tense and a force is applied in the direction of pulling out the lid 6. The force in this direction acts as a tensile force on the breaking rod 8. When this tensile force becomes larger than the design value, the breaking rod 8 breaks at the reduced diameter portion 8b.

When the breaking rod 8 breaks, the upper part of the reduced diameter portion 8b of the breaking rod 8 is pulled out from the rope storage box 2 together with the lid 6. Since the tip side connecting fitting 5 is fixed to the support plate portion 6b of the lid body 6, the tip side connecting fitting 5 is also pulled out together with the lid body 6. Since the tip of the extension rope 3 is fixed to the tip of the tip-side connection fitting 5, the extension rope 3 is pulled out from the rope storage box 2 as the ship rises or moves. Since the base end portion of the extension rope 3 is fixed to the base end side connection fitting 4 fixed to the bottom plate 2a of the rope storage box 2 embedded and installed in the quay G , the extension rope 3 is fixed to the quay G. Never leave. Moreover, the rope storage box 2 is easily pulled out because the protruding portion 51 projecting from the outer surface of the rope storage box 2 opposes the tensile force for pulling out the rope storage box 2 from the quay G. There is no. Therefore, the behavior of the ship is regulated within the range of the length of the extension rope 3, and by adjusting the length of the extension rope 3 appropriately, capsizing or drifting of the ship can be prevented. .. Further, since the base end side connection fitting 4 and the tip end side connection fitting 5 to which the extension rope 3 is fixed are swingably supported around the shafts 4a and 5a, respectively, the ship is restrained by the extension rope 3. Even when the support rods 4 and 5 are floated, the support rods 4 and 5 swing and the ship is allowed to float to some extent.

As described above, the extension rope 3 needs to be smoothly pulled out from the rope storage box 2 as the ship rises. Therefore, the rope storage box 2 is not provided with a portion that hinders the extension rope 3 from being pulled out. Further, as shown in FIG. 1, it is preferable to arrange the ropes in such a way that they are spirally wound and laminated along the peripheral wall of the rope storage box 2 so as to be surely pulled out from the upper part. It is preferable to arrange the breaking rod 8 in the center of the above.
