Description

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

  Ships that have entered the port for berthing are anchored with mooring ropes such as ropes and wire ropes attached to mooring pillars protruding from the quay or pier, and the berthing is prevented. Generally, a berthing facility such as a quay is designed to have a height that does not hinder passengers on the ship and unload cargo even when the water level changes due to sea level rise and fall according to the tidal range. Further, even when a large wave hits the quay, such as when a tide and a typhoon overlap, there is no problem in berthing of a vessel moored by a mooring rope on the mooring column. In addition, fenders are attached to the berthing facility so that the ship and the berthing facility are not damaged.

  By the way, in recent years, a tsunami far exceeding expectations has occurred due to the occurrence of a major earthquake, and it is a new memory. When the sea level abnormally rises due to such a tsunami or the like, the ship moored to the mooring column by the mooring rope rises as the sea level rises. If the sea level rises more than expected, there is a risk that the ship will capsize.

  8 and 9 show a state where the ship S is stopped by the mooring rope 22 on the mooring column 21 provided on the quay G. FIG. 8 shows a normal condition, and the ship S also moves up and down as the sea level L rises and falls due to tides, but the height of the quay G does not interfere with getting on and off the ship S or handling cargo. Has been. On the other hand, when the sea level L rises to an unexpected height due to a storm or tsunami and exceeds the height of the quay G, the ship S rises in the sea level L as shown in FIG. Ascend beyond the height of the quay G. The mooring rope 22 has a length sufficient to maintain the state where the ship S is berthing, so that when the sea level L rises abnormally, it is between the mooring column 21 and the sea level L. May be longer than the length of the mooring rope 22. In such a case, as shown in FIG. 9, the boat S may be restrained by the mooring rope 22, and the anchor side on which the mooring rope 22 is hooked may be drawn and overturned. In addition, the tensioned mooring rope 22 may break, and the ship S may be carried by the tsunami and drifted, or carried by the land and stranded.

  As a vessel mooring device for preventing ship capsize when the sea level rises abnormally, in a vessel mooring device that connects a ship that has berthed and a mooring column by a mooring rope, the base of the mooring column that links the mooring rope is accommodated. A holding hole is formed in the quay wall, a receiving hole continuous with the holding hole is formed, an extension material is received in the receiving hole, and a distal end portion of the extension material is fixed to a base portion of the mooring column, and the extension material The base end of the base is fixed to an arbitrary part, and the length of the extension member extending from the quay is made larger than the distance between the sea level rising to an abnormal height and the quay. A ship mooring device has been proposed in which holding means for holding the base of the mooring column is provided in the holding hole, and when seawater enters the holding hole, the holding means is released to free the mooring column. (See Patent Document 1).

Japanese Patent Laying-Open No. 2015-38274

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

  In addition, since the structure in which the holding means is released by intrusion of seawater is adopted, for example, when the sea level is abnormally rising such as a tsunami, the invaded seawater behaves violently and the release of the holding means is released. May prevent it. On the other hand, if the holding force by the holding means is reduced so that it can be easily released by the intrusion of seawater, the holding means will be inadvertently released in the event that a storm wave such as a typhoon hits the quay. There is a risk that the ship will leave the quay.

  Therefore, the present invention prevents as much as possible that a ship moored on the quay at the time of an abnormal rise in tide level such as a tsunami, is restrained by the mooring rope and overturns, or that the mooring rope drifts away from the mooring column. It aims at providing the ship mooring apparatus which can do.

Are separated.

  When the ship rises due to an abnormal rise in the sea level caused by the invasion of a tsunami or the like and the mooring rope is pulled up, the separation member is loaded at that time, and the separation member is separated. As a result, the separation-side separation member is detached from the fixed-side separation member, and the rope hooking member that is linked and fixed to the separation-side separation member can be lifted as the ship rises. . Since the extension rope is connected to the rope hooking member, the extension rope is pulled out by the rise of the rope hooking member, allowing the vessel to be lifted, and within the range of the length of the extension rope. Ships are regulated.

  The ship mooring device according to the invention of claim 2 is a ship mooring device for connecting a berthing ship and a mooring facility by a mooring rope, wherein the extension rope is housed in a rope housing box and connected to the bottom plate of the rope housing box.

  When the ship rises due to an abnormal rise in the sea level, the lid body is detached from the rope storage box, and the rope stored in the rope storage box is pulled out to allow the ship to rise.

  Further, in the ship mooring device according to the invention of claim 3, a part of the separating member is reduced in diameter to form a reduced diameter part, and the reduced diameter part is broken and separated by a tensile force caused by the rising of the ship. It is characterized by.

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

  Further, in the marine mooring device according to the invention of claim 4, the separating member is constituted by a separating side separating member on the mooring rope side and a fixed side separating member on the quay side, and these separating side separating member, fixed side separating member, Are connected by a shear pin, and when the ship is lifted, the shear pin is broken by the shear force, and the separating member is separated.

  The shear pin connecting the separation-side separation member and the stationary-side separation member is subjected to a shearing force due to the separation-side separation member being pulled up with respect to the stationary-side separation member due to the rise of the ship due to an abnormal rise in the sea level. Break. Thereby, the said extension rope is pulled out and a raise of a ship is accept | permitted.

  Further, the marine mooring device according to the invention of claim 5 is provided with a pair of separation member elements of the separation side separation member and the fixed side separation member as a pair, and the other is arranged in a part of the pair of separation member elements.

  Hereinafter, the ship mooring apparatus according to the present invention will be described in detail based on the illustrated preferred embodiments.

  FIG. 1 shows a schematic structure of a ship mooring device 1, which is installed on a quay G that is a berthing facility of a ship. A rope storage box 2 is installed on the quay G, and an extension rope 3 is stored in the box. The base plate 2a of the rope storage box 2 is provided with a base end side connection fitting 4 whose base end is swingable about the shaft 4a. The extension rope is attached to the tip end of the base end side connection fitting 4. The base end portion of 3 is fixed.

  The top of the rope storage box 2 is covered with an annular top plate 2b, and the periphery of the top plate 2b is fixed by being dropped into a counterbore formed on the quay G. 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 into the annular inner side of the top plate 2b.

  The lid body 6 includes a support plate portion 6b to which the fitting convex portion 6a is fixed, and a lid body portion 6d that covers the support plate portion 6b. The support plate portion 6b is formed with a sufficiently large through-hole portion 6c capable of performing an operation described later, and is connected to the top plate 2b via a rotation prevention shear pin 7. . A lid portion 6d is fixed to the upper surface of the support plate portion 6b by fixing bolts 6e. And the U-shaped mooring pillar 9 as a rope latching member of the rope fixing metal fitting the mooring rope (refer FIG. 8) extended from a ship is fixed to the upper surface of this cover body part 6d. The support plate portion 6b and the top plate 2b are provided with a waterproofing material 2c as a water blocking means, and seawater enters the inside of the rope storage box 2 from the gap between the top plate 2b and the support plate portion 6b. Is prevented from entering.

  On the lower surface of the fitting convex portion 6a of the lid body 6 is provided a distal end side connection fitting 5 whose base end is swingable about the shaft 5a. The tip of the extension rope 3 is fixed.

  A through hole 6f is formed at the center of the fitting convex portion 6a, and the upper end portion of the breaking rod 8 as a separating member passes through the through hole 6f, and this upper end portion is the through hole portion 6c. It is located in. A male screw portion is formed at the upper end portion of the fracture rod 8, and a tightening nut 8a is screwed into the male screw portion. For this reason, the size of the through-hole portion 6c is set such that an operation of tightening the tightening nut 8a to the upper end portion of the fracture rod 8 can be performed. A lower end portion of the breaking rod 8 is fixed to the bottom plate 2 a of the rope storage box 2. The fracture rod 8 is formed with a reduced diameter portion 8b so as to break when a predetermined tensile force is applied, as will be described later. The upper side of the reduced diameter portion 8b is a separation side separating member, and the lower side is a fixed side separating member.

  In order to install this marine 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 distal end side of the extension rope 3 is fixed to the distal end portion of the distal end side connection fitting 5, and is accommodated in the rope accommodation box 2. While the fitting convex portion 6a of the lid 6 is fitted 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. 6b is placed on the top 2b. At this time, the support plate portion 6b is connected to the top plate 2b by the shear pin 7. Further, these gaps are sealed by the waterproof material 2c in a state where the support plate portion 6b is placed on the top plate 2b.

  Then, when the tightening nut 8a is tightened to the male screw portion at the upper end portion of the breaking rod 8 exposed in 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 and the waterproofing is performed. The material 2c comes into close contact with the top plate 2b, and the intrusion of seawater from the gap between the support plate portion 6b and the top plate 2b is prevented.

  Next, when the lid body portion 6d is fixed to the support plate portion 6b by the fixing bolt 6e, the rope housing box 2 is covered with the lid body 6 and closed, and the U-shaped mooring column protrudes from the quay wall G. The ship mooring apparatus 1 is installed.

  When the ship is berthed at the ship mooring device 1 installed as described above for anchoring, the mooring rope extended from the ship is tied to the U-shaped mooring column 9. During normal times, the sea level rises and falls in a range lower than the upper surface of the quay G due to tidal waves and waves, and boarding and unloading and cargo handling are performed stably. Further, even when the tension on the mooring rope changes due to the behavior of the ship, the lid body 1 provided with the U-shaped mooring column 9 has the shear pin 7 between the lid body 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 tensioned and the lid 1 is about to be pulled out, it is not pulled out because it is restrained by the breaking rod 8. For this reason, the state where the ship was moored at the quay G via the mooring rope is maintained in normal times, like a normal mooring column.

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

  When the breaking rod 8 breaks, the upper portion 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 distal end side connection fitting 5 is fixed to the support plate portion 6 b of the lid body 6, the distal end side connection fitting 5 is also pulled out together with the lid body 6. And since the front-end | tip part of the extension rope 3 is being fixed to the front-end | tip part of this front end side connection metal fitting 5, this extension rope 3 is pulled out from the rope storage box 2 according to a raise or movement of a ship. 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 installed on the quay G, the extension rope 3 is detached from the quay G. There is nothing. For this reason, the behavior of the ship is restricted within the range of the length of the extension rope 3, and by making the length of the extension rope 3 appropriate, the capsizing and drifting of the ship can be prevented. . In addition, since the proximal end connection fitting 4 and the distal end connection fitting 5 to which the extension rope 3 is fixed are supported swingably around the shafts 4a and 5a, respectively, the ship is restrained by the extension rope 3. Even when floating, the support rods 4 and 5 swing to allow the ship 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. For this reason, the part which becomes an obstacle when the extension rope 3 is pulled out is not provided in the rope storage box 2. Further, as shown in FIG. 1, it is preferable to arrange the layers so as to be surely pulled out from the upper part by laminating them while being spirally wound along the peripheral wall of the rope housing box 2. It is preferable to arrange the breaking rod 8 in the center of the.
