Description

The present invention relates to a mooring facility that is installed in a boundary area between a river and land and serves as a physical distribution base for cargo for ships.

As a method of transporting cargo, it is common to use land routes, but in some countries, cargo is transported by transporting cargo on rivers (for example, Myanmar's Yangon River, Ayeyarwaddy River, etc.). Karadan River, Craburi River, Kok River, Salween River, Sittaung River, Chindwin River, Bago River, Mekong River, Moei River, Paraguay River in Paraguay, Parana River, Ganges River in Bangladesh, Meghna River, Feni River, Brahmaputra River, Mukhuri River, etc.). Unlike the rivers in Japan, these rivers are characterized by slow flow and wide width, and in cases where the road network is not sufficiently developed, river transport using carrier ships is advantageous in terms of convenience. be.

By the way, the water level of these rivers varies greatly between the rainy season and the dry season (about 7 to 10m), and the land side is not sufficiently developed. It is not easy to install berthing facilities such as In other words, such facilities require construction work to improve the embankment, reclamation work in the boundary area between the river and the land, and construction work to install a pier where ships can be docked. is difficult. In particular, some of the above-mentioned rivers are in a winding state, and there is a possibility that the position where a ship berths will change due to erosion, flooding, etc. with the passage of time. Installation of equipment is not appropriate.

Therefore, the cargo transportation work using rivers in the country as described above is carried out by many people while the cargo is brought close to the land without installing mooring facilities. This is an inefficient situation, as workers are forced to work with loads placed overhead.

BACKGROUND ART For example, a mooring device disclosed in Patent Document 1 is known as a structure for mooring a ship on land. This mooring device is for mooring a floating pier on which a ship can dock, and includes a pair of pedestal struts installed on the bottom of the water and a swinging stanchion swingably held by these pedestal struts. One end of the swinging strut is swingably connected to a base fixed to the bottom of the water, and the other end of the swinging strut is connected to a floating pier via a connecting chain.
This mooring device is a structure to prevent the floating pier from drifting when a big wave hits. It is possible.

JP 2017-43356 A

By the way, rivers in Japan are characterized by rapid currents and narrow river widths, and because land transportation networks are well-developed, there is no need to install mooring facilities for transport ships in rivers.
However, there are cases where development assistance is provided for infrastructure development, etc., to countries that are engaged in river transportation as described above. In such a case, the current situation is that there is no suitable mooring equipment for rivers (design concept of mooring equipment). problem arises.

Since the floating pier can be moved along the horizontal plane by a swinging structure configured as a parallel crank, it is not possible to stably carry in and carry the cargo while the carrier is lined up.
Since the floating pier has a parallel crank structure and is fixed to the bottom of the water, it is necessary to firmly fix the foundation to the bottom of the water, which increases the installation cost. Moreover, since the rocking structure is provided between the floating pier and the bottom of the water, the installation cost becomes high.
The floating pier has a structure that is fixed to the bottom of the water so that it does not drift when there is a large change in the water surface such as a tsunami.

The present invention has been made in view of the above-mentioned problems, and can be installed movably in any riverside area of a river, and can carry cargo in and out in a stable state by lining a carrier ship. The object is to provide mooring facilities easily and at low cost.

In countries where goods are transported by rivers as described above, shipyards are often set up adjacent to rivers. In the present invention, focusing on such circumstances, a mooring facility having the following configuration is constructed at a shipyard, launched into a river as it is, towed by a tugboat, and installed in an arbitrary riverside area. It is characterized by configuring

That is, in order to achieve the above-described object, the mooring equipment according to the present invention is fixed and installed in the river edge area of a river, can be towed by a tugboat while floating on the water surface, and is a base to which a carrier ship is moored. A base, a through hole formed on the outer edge side of the base, installed by vertically inserting into the through hole, driven by a drive mechanism so as to be vertically movable with respect to the base, and capable of being grounded on the bottom of the water. and a bridging member which is movably provided on the base and enables the transportation vehicle to enter and exit between the land side and the base.

In the mooring equipment having the above-described configuration, a base on which a carrier ship is moored is fixed and installed in a river edge region of a river. A through hole is formed in the base, and a spud is inserted through this portion so as to be vertically movable, and the base is fixed in a state of being grounded on the bottom of the water by a driving mechanism. At this time, the base is restrained from moving on the surface of the water by the spud, and is held in a stable state. For this reason, even if a transport vehicle enters through the bridging member while the transport ship is laid alongside the base, it is possible to stably carry out the loading and unloading operations of the cargo. In addition, since the base floats on the surface of the water, the spud can be towed while being lifted, making it possible to easily change the location and install it. Furthermore, the base can be launched directly from the shipyard installed along the river and towed by a tugboat, so the structure is simple and the cost for installation can be reduced.

To provide a mooring facility which can be movably installed in an arbitrary riverside area of a river, can be lined with a carrier ship, and can carry in and out cargo in a stable state, easily and at a low cost. becomes possible.

The figure which shows one structural example of the drive mechanism arrange|positioned at a spud and a base. (a) and (b) are diagrams showing a state in which the spud is vertically moved by the drive mechanism. The schematic of the state which installed the mooring equipment which concerns on the 2nd Embodiment of this invention in the river.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of the mooring installation which concerns on this invention is described, referring drawings.
1 to 3 are diagrams showing the mooring equipment according to the first embodiment of the present invention, FIG. 1 is a schematic diagram of the mooring equipment installed in a river, and FIG. 3(a) and 3(b) are diagrams showing a configuration example of the mechanism, and diagrams showing a state in which the spud is vertically moved by the drive mechanism.

The mooring facility 1 includes a base (pontoon) 3 on which a carrier ship 100 is berthed. The base 3 of this embodiment has a substantially rectangular shape, the length of the long side (the length in the direction along the flow of the river) is about 40 to 60 m, and the length of the short side (long side The length of the side perpendicular to the wall) is about 20 to 30 m, and the depth (thickness) is about 2 to 5 m.

The base 3 may be constructed so as to float on river water, and may be constructed of a hollow structure, a solid structure, a combination of these structures, or the like. may be combined and connected. In this case, such a base 3 is manufactured at a shipyard along the river and can be launched by sliding it as it is. It is preferably constructed by connecting about 4 to 5 plate bodies.
In addition, as will be described later, the transport vehicle 110 is mounted on the base 3, and a crane device 50 for handling cargo is installed. Good luck.

The base 3 may be configured to receive and drain ballast water by a pump so that the weight of the base 3 itself can be adjusted. may be held in a state separated from. Moreover, the size and shape of the base 3 can be appropriately modified according to the size of the river, the type of cargo to be transported, the size of the transport ship to be laid alongside, and the like.

The base 3 is non-self-propelled and can be towed by a tugboat (tugboat) or the like, and is movable in the river. Of course, it may be configured as a self-propelled type by mounting a thruster or the like.

A bridging member 5 is provided on the base 3 to allow the transportation vehicle 110 to enter and exit between the land side 300 and the base 3 . The bridging members 5 of this embodiment are provided at two locations along the river at predetermined intervals. Each bridging member 5 is movably installed on the surface of the base 3 , and in this embodiment, is rectangular and rotatably installed on the surface of the base 3 . A winch 8 for winding the wire 7 and a pair of posts 9 for pulling up the wire 7 at a fixed height position are installed on the surface of the base 3 .
Thereby, the bridging member 5 is rotationally driven by the drive of each winch 8, and it becomes possible to form the carry-in route 5A and the carry-out route 5B with the land side 300. FIG.

A spud 10 is installed on the outer edge side of the base 3 . The base 3 of the present embodiment is formed in a substantially rectangular shape as described above, and the spuds 10 are arranged on the outer edge side of the base 3 (at four corners), one each, for a total of four spuds. This is installed (in multiple places on the base). Each spud 10 has the same structure, and is driven by the drive mechanism 15 so as to be vertically movable with respect to the base 3 , and can be grounded while one end is in contact with the bottom 210 .

As shown in FIG. 2, the base 3 is formed with a through hole 11 through which the spud 10 passes. A shaped spud support housing (hereinafter referred to as a housing) 12 is installed. The spud 10 is inserted through the through-hole 11 and the housing 12 and has one end extending into the water and the other end protruding upward from the surface of the base 3 . A plate-like contact portion 10A is provided at the end of the spud 10 on the water bottom side so that the spud 10 can be brought into contact with the water bottom 210 for stabilization.

The number and installation position of the spuds 10 are not particularly limited as long as they are inexpensive and can stably hold the base 3 .

2 and 3, the drive mechanism 15 is arranged between a plurality of drive motors (hydraulic motors) 16 arranged in the housing 12 and the drive motors 16 and the spud 10. A power transmission mechanism 17 is provided. The configuration of the power transmission mechanism 17 is not limited, but in this embodiment, a rack 17a is formed on the outer surface of the spud 10 along the longitudinal direction, and a constant It is constructed by a rack and pinion system provided with pinions 17b that mesh with each other at intervals. Therefore, when the pinion 17b is rotationally driven by the driving motor 16, the spud 10 is driven downward (see FIG. 3(a)) or upward (see FIG. 3(b)).

The base 3 described above is towed by a tug board and installed at an arbitrary position along the river. When the base 3 is moving on the water, each spud 10 is held in a raised position by the driving mechanism, so that the movement of the base 3 is not hindered. When the base 3 reaches a predetermined position, each spud is lowered by the driving mechanism 15, and the abutment portion 10A at the tip abuts the bottom of the water, thereby positioning the spud.

A clutch mechanism may be provided in the power transmission mechanism 17, and power transmission to the spud 10 may be interrupted. That is, after the spud 10 abuts on the bottom of the water and is fixed at a predetermined position, the rack 17a and the pinion 17b are brought into a non-transmitting state so that the casing 12 (base 3) and the spud 10 are in a free state. can be configured to As a result, even if the water level of the river changes, the base 3 stays in a floating state without being horizontally moved by the spuds 10, and is positioned. It is possible to move up and down (follow changes in the water surface) without floating.

Note that the spud 10 and the base 3 may be maintained in a power transmission state in which the rack 17a and the pinion 17b are engaged as described above. In such a power transmission state, by setting the engagement force between the two to be equal to or less than the buoyancy acting on the base 3, the base 3 can follow changes in the water surface.

Preferably, the base 3 is provided with a winch 20 connected to a fixing member (for example, a bollard or the like) installed on the land side 300 .
By providing such a winch 20, the base 3 can be stably moored.

In addition, a rotatable crane device 50 is installed on the base 3 of the present embodiment for loading and unloading cargo with respect to the transport ship 100 that is laid alongside. The crane device 50 includes a support portion 51 installed and fixed on the base 3 and an arm portion 52 rotatably installed on the support portion 51. The winch 53 and the hook 54 enable the cargo transfer operation between the transport ship 100 and the transport vehicle 110 that has entered the base 3 .

A hydraulic control unit 60 is installed on the base 3 of the present embodiment, and drive elements such as the drive mechanism 15 for each spud, the winch 8 for rotating the bridging member 5, and the crane device 50 are driven and controlled at one location.

In this embodiment, as described above, two bridging members are provided on the base 3 at predetermined intervals. is taken as the unloading route 5B. In this case, by installing the crane device 50 in the middle region of the bridging members (carrying-in route 5A, carrying-out route 5B) on both sides, the transport vehicle 110 boarded on the base 3 is stopped to carry in the cargo. Therefore, it is possible to adopt an arrangement mode in which the transport vehicle 110 carrying the cargo is moved to the land side 300 as it is via the other bridging member without being reversed. As a result, it is possible to realize an efficient transportation operation of the cargo.

According to the mooring facility 1 as described above, in areas where physical distribution is performed using rivers, it is necessary to carry out reclamation work for berthing transport ships and installation work such as piers where ships can be docked. It will be possible to carry in and out cargo from a carrier ship at low cost. In this case, the base 3 of the mooring equipment can be vertically displaced while its horizontal movement is restricted by the spud 10, so that the base 3 is stabilized even if the water surface changes. In addition, since the carrier vehicle 110 can be driven into the base 3 and the cargo can be carried in and out by the crane device 50, a large number of workers are not required, and efficient transportation work can be performed. Furthermore, since the spud 10 can be lifted from the base 3 and the position of the base 3 can be easily changed in accordance with the river conditions, there is no need to provide berthing equipment for a carrier ship at a specific position, which wastes equipment. It won't be.

FIG. 4 is a diagram showing mooring equipment according to a second embodiment of the present invention.
The second embodiment will be described below, but the same reference numerals are given to the same configurations as in the first embodiment, and detailed description thereof will be omitted.

Protrusions 3A and 3B projecting along the water flow direction are formed on the tip side of the base 3 of this embodiment in a state of being installed in a river. As described above, the size and shape of the base 3 are not limited. Of the land-side regions P1 and P2, the downstream land-side region (referred to as P2) is less susceptible to the influence of the current, and thus the transport ship can be stably alongside.

Further, in this embodiment, the base 3 is provided with three spuds 10, and instead of providing the above-described crane device on the base 3, a self-propelled crane vehicle 50A can be installed as necessary. I'm trying to get in. Furthermore, the bridging member 5 is installed at one place.

According to such a mooring facility, since the number of constituent elements is smaller than that of the first embodiment, the cost can be further reduced.

If the ground on the land side 300 is muddy, etc., the area where the bridging member 5 is set is paved with concrete or an iron plate member 330 is laid (see FIGS. 1 and 4). For example, the boundary portion may be stabilized. Also, at the portion where the spud 10 abuts on the bottom of the water, a foundation member 350 may be installed or simple foundation work may be performed so that the spud is stabilized.

Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the above-described embodiments, and various modifications are possible.
The drive mechanism 15 and the power transmission mechanism 17 described above are examples, and can be appropriately modified as long as the same functions can be exhibited. For example, the driving mechanism for vertically driving the spud 10 can be constructed by winding and unwinding a winch. In addition, although the bridging member 5 is of a rotating type, it can be appropriately modified such as by a sliding type.
