Description

  The present invention relates to a mooring device for a pneumatic fender, and more particularly, to reduce the impact force applied to the suspension fitting, mooring tool and mooring line of the pneumatic fender body due to waves and the like, and to reduce the height of the quay. The present invention relates to a mooring device for a pneumatic fender that prevents the air fender from getting on the quay even if it is suppressed.

  Conventionally, a pneumatic fender has been installed on the wall of a quay at a port in order to prevent damage to the hull and the quay at the time of ship berthing. As shown in FIG. 6, the pneumatic fender 1 is a hollow substantially fender-shaped fender main body made of an elastic material such as rubber, and is provided on the upper surface 12 of the quay. The anchor 14 is used by being suspended by a mooring line 2 such as a chain or a rope. The length of the mooring line 2 is set with a margin so that the pneumatic fender 1 can always follow fluctuations in the water level due to draft changes and tidal differences, but if the water level fluctuates rapidly due to waves, etc. It is inevitable that an excessive impact force is applied to the mooring line 2, and the suspension fitting 10 of the main body of the pneumatic fender 1, the shackle 7 that is the mooring tool, the swivel 8, and the towing ring 9 are worn out. However, there is a problem that the life of the quay is shortened due to wear due to strong sliding contact with the upper surface 12 and the corner portion 13 of the quay.

  In order to solve such a problem, Patent Document 1 proposes a suspension device in which an elastic member is provided at a lower portion of a supporting member that supports the mooring line 2 on the upper surface 12 of the quay, and thereby the mooring line 2 is attached to the mooring line 2. Such impact tension is relaxed.

However, the pneumatic fender 1 may ride on the upper surface 12 of the quay when the water level rises greatly or a big wave occurs. Such a problem is prevented by the apparatus of Patent Document 1. Can not do it. If the height of the quay is taken as a countermeasure, the cost for quay construction will increase.

  The object of the present invention is to extend the life of the suspension fittings, mooring tools and mooring lines of the pneumatic fender body, and to prevent the fenders from climbing onto the quay even if the height of the quay is kept low. An object of the present invention is to provide a mooring device for a pneumatic fender.

  A mooring device for a pneumatic fender according to the present invention that achieves the above object is the mooring device for a pneumatic fender that suspends a pneumatic fender on a wall surface of a quay by a mooring line. The other end of the mooring line connected to the material is fixed to the wall surface, and the mooring line is made of a rubber rope or a chemical fiber rope reinforced with a reinforcing fiber, and a steel chain is connected to the pneumatic type It is characterized by being arranged in parallel between the brazing material and the wall surface.

  It is desirable that the length at which the stretchable rope is pulled and broken is shorter than the length of the steel chain. Moreover, it is desirable to install a chain net on the outer surface of the pneumatic fender.

  According to the mooring device for pneumatic fenders of the present invention, the other end of the mooring line connected to the pneumatic fenders is fixed to the wall surface of the quay and the mooring line is reinforced with a reinforcing fiber or a chemical rope. Since the stretch rope made of fiber rope and the steel chain are arranged in parallel between the pneumatic fender and the quay wall, it is added to the chain due to fluctuations in the water level due to waves etc. The impact force is alleviated by the expansion and contraction of the elastic rope, the shackle, swivel and towing ring of the pneumatic fender body, and the chain slides on the quay's upper surface and corners. Since they do not wear out in contact, their life can be extended. In addition, the elastic rope can restrict the vertical movement of the pneumatic fender to a certain range, preventing the air fender from getting on the quay even if the height of the quay is kept low. can do.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG.1 and FIG.2 shows the example which moored the pneumatic fender to the quay by the mooring apparatus of the pneumatic fender which consists of embodiment of this invention.

  This mooring device for pneumatic fenders suspends a pneumatic fender 1 from two mooring lines 2 on a wall surface 3 of a quay. The air fender 1 has a hollow, substantially saddle shape formed by laminating a rubber material and a reinforcing material. Air is sealed inside and floats on the water surface. On the outer surface of the pneumatic fender 1, a chain net 4 in which a plurality of tires are connected in a mesh pattern with a string-like member such as a chain in order to protect the pneumatic fender 1 from contact with a ship or a quay. Is installed.

  The mooring cable 2 is composed of a stretchable rope 5 and a steel chain 6 connected in parallel, one end of which is fixed to the end of the pneumatic fender 1 and the other end is fixed to the wall 3 of the quay. Has been. As the stretchable rope 5, a rubber rope or a chemical fiber rope reinforced with a reinforcing fiber is used. Specifically, as shown in FIG. 3, one end of the stretchable rope 5 and the steel chain 6 is attached to a mooring tool such as a shackle 7, a swivel 8 and a towing ring 9, or an end of the pneumatic fender 1. It is connected to the end portion of the pneumatic fender 1 via a fixed hanging metal fitting 10 or the like, and the other end is fixed to the wall surface 3 of the quay via a shackle 7 and a U-shaped pad 11 with an anchor.

  It is preferable that the stretchable rope 5 has a highly stretchable structure such as a twisted structure with a large number of twists or a knitted structure. The stretch length is 10 to 50%, preferably 20 to 30%, when stretched at break. Examples of the reinforcing fiber include nylon and polyester, and examples of the chemical fiber include polypropylene and nylon.

  As described above, since the mooring device for the pneumatic fender is configured, as shown in FIGS. 4 and 5, the impact force applied to the chain 6 due to the fluctuation of the water level due to waves or the like is mitigated by the expansion and contraction of the elastic rope 5. The shank 7, the swivel 8, the swivel 8 and the towing ring 9 of the pneumatic fender body, or the chain 6 slidably contacts the upper surface 12 and the corner 13 of the quay. Since they do not wear out, their lifetime can be extended. Moreover, since the vertical movement of the pneumatic fender 1 can be limited to a certain range by the stretchable rope 5, even if the height of the quay is kept low, the pneumatic fender 1 can be moved to the quay. Riding can be prevented.

  The length that the stretchable rope 5 is broken by tension is shorter than the length of the chain 6 so that the pneumatic fender 1 can be moored by the chain 6 even if the stretchable rope 5 is broken. It is desirable to do.

  In this embodiment, both ends of the pneumatic fender 1 and the wall surface 3 of the quay are connected to each other by one stretchable rope 5 and one chain 6. The number and the connection location with the pneumatic fender 1 are not limited to this.

It is a front view which shows the example which moored the pneumatic fender to the quay by the mooring apparatus of the pneumatic fender which consists of embodiment of this invention. It is a side view of FIG. It is a mooring line in the mooring apparatus of the pneumatic fender which consists of embodiment of this invention. In FIG. 1, it is a front view which shows the change of the mooring apparatus of a pneumatic fender when a water level rises. FIG. 5 is a side view of FIG. 4. It is the conventional mooring device of a pneumatic fender, (a) shows a front view, (b) shows a side view, respectively.
