The loading platform 10 is preferably formed of a rust-proof steel material, stainless steel, aluminum, or other material having high seawater resistance.

As shown in FIG. 1, a loading platform 10 having a rectangular shape in plan view is supported in a floating state on the water surface by two floats 16, 17 arranged at parallel intervals in the width direction. ing.

In this embodiment, the floats 16 and 17 are formed of hollow elongated can bodies extending in the front-rear direction and having substantially the same shape and length.

Next, the structure of each of the floats 16 and 17 will be described.

Each of the floats 16 and 17 is composed of a can body having a hollow trapezoidal cross section whose both ends are closed in a watertight state. It is placed and supported.

Each of the floats 16, 17 has an upper half float 16a, 17a having a substantially semicircular cross section with an open upper surface, and a lower half float 16b, 17b having a substantially semicircular cross section with a lower surface opened.
It is formed by connecting in an airtight and watertight manner via 16c and 17c.

The floats 16 and 17 have their internal spaces defined by partitions 8 and 9 in the longitudinal direction, and have front and rear airtight chambers 16d and 16d.
16e, 17d, and 17e.

The upper and lower surfaces of the floats 16 and 17 are provided with air supply / exhaust openings 30a, 30b, 31a and 31b communicating with the airtight chambers 16d, 16e, 17d and 17e. Opening
30a, 30b, 31a, 31b are flexible supply / exhaust hoses 33a, 33b,
It is connected to the air supply / exhaust tube 21 having an air pressure pump (not shown) through 34a and 34b.

On the other hand, the water supply / drainage opening 35 communicating with the above-mentioned airtight chambers 16d, 16e, 17d, 17e is formed on the lower surface of the front and rear portions of each float 16, 17.
a, 35b, 36a, 36b are provided.
Water supply / drainage pipes 37a, 37b, 38a, 38b are connected to b, 36a, 36b.

The floats 16 and 17 have buoyancy buoys 25, 25a, 41 and 42 connected to their front and rear end upper surfaces by cords 24, 24a, 39 and 40, respectively. The buoyancy buoys 25, 25a, 41, 42 are used to hold the floating platform A at a certain depth below the surface of the water when the small boat B is mounted on the boat.

The present invention relates to a floating dock A having the above-described structure.
At this time, as shown in FIG. 2 and FIG.
The partition walls 8 and 9 provided in 7 are provided with a pair of upper and lower partition walls 8a, 8b, which are provided inside the floats 16 and 17 at parallel intervals in the longitudinal direction.
9a, 9b, opening the lower part of the upper partition walls 8a, 9a to form lower communication ports 8c, 9c,
The upper communication opening 8d, 9d is formed by opening the upper part of b, and the front airtight chambers 16d, 17d are connected between the lower communication opening 8c, 9c and the upper and lower partition walls 8a, 8b, 9a, 9b, respectively. It is characterized in that communication is possible via the spaces 8e, 9e and the upper communication ports 8d, 9d.

With this configuration, the supply / exhaust tube is
By actuating the air pressure pump provided in 21 and opening the open / close valve for air and the open / close valve for water (not shown), air is supplied to the airtight chambers 16d and 16e via supply / exhaust hoses 33a, 33b, 34a and 34b. , 17d, 17e, the airtight chambers 16d, 16e,
The water level in 17d, 17e gradually decreases, but the communication space 8e, 9e
Since water is retained inside, the airtightness between the airtight chambers 16d and 16e and the airtight chambers 17d and 17e is maintained.

Further, when the water level in the airtight chambers 16d, 16e, 17d, 17e drops and there is no water in the communication spaces 8e, 9e, the airtightness between the airtight chambers 16d, 16e and the airtight chambers 17d, 17e is maintained. However, the air pressure in both airtight chambers 16d and 16e becomes constant, and water can be reliably excluded from all airtight chambers 16d, 16e, 17d and 17e. it can. After that, the overhead work is completed by closing each opening / closing plug.

As described above, instead of using a single partition, two divided partitions 8a, 8b, 9a, and 9b each having a communication port can be used to provide a space between the airtight chambers 16d and 16e and between the airtight chambers 17d and 17e. Sufficient airtightness (and, if necessary, watertightness) can also be achieved, and the work of vertically lifting the pontoon A can be performed smoothly and reliably.

That is, when one partition wall is used as in the conventional case, it is necessary to completely secure the airtightness and the watertightness between the airtight chambers, so that it is necessary to mount the partition wall precisely inside the float over time. However, such mounting work is complicated, but when two partition walls 8a, 8b and 9a, 9b are used as in this embodiment, it is necessary to consider the airtightness and watertightness described above. Since there is no such, the partition walls 8a, 8b and 9a, 9b can be quickly and easily attached to the floats 16,17,
The manufacturing costs of the floats 16 and 17 can be significantly reduced.

Specifically, the partition walls 8a, 8b and 9a, 9b
Can be quickly and easily attached to the floats 16 and 17 using an adhesive, and can also be attached quickly and easily by welding when the floats 16 and 17 are made of synthetic resin.

The other structural features of the floating dock A according to this embodiment will be specifically described below.

As shown in FIGS. 1 and 2, partition walls 8 and 9 are provided at positions deviated in the longitudinal direction from the central portions of the floats 16 and 17, and the airtight chambers 16d, 16e, 17d and 17e are formed in the front and rear directions. It is characterized in that it is divided unequally and its space volume is made different.

[0034] With this configuration, the supply and exhaust cylinders
By operating the air pressure pump provided in 21 and opening the air opening / closing stopper (not shown) and the water opening / closing stopper, air is supplied to the airtight chambers 16d, 16e through supply / exhaust hoses 33a, 33b, 34a, 34b. , 17d, 17e, the airtight chambers 16e, 17e having a small space volume become the airtight chambers 16d, 17d having a large space volume.
First, the water remaining inside is drained into the water supply and drainage pipes 37a and 37a.
It can be quickly discharged to the outside through b, 38a, 38b.

Accordingly, the buoyancy on the rear side of the float 16 becomes larger than the buoyancy on the front side, and the pontoon A is in a front-low-back-high state and is inclined in the front-rear direction. This acts as a force that suppresses or absorbs the inclination of the pontoon A in the left-right direction, so that it is possible to reliably prevent the pontoon A from overturning when it is mounted. Further, even when the vehicle does not overturn, the inclination in the left-right direction can be effectively suppressed, so that the passenger does not have a sense of crisis.

Thereafter, the airtight chambers 16d and 17d having a large space volume are provided.
The water inside also goes out completely, so that the front parts of the floats 16 and 17 are lifted and the floats 16 and 17 become horizontal. Finally, the overhead work is completed by closing the air and water stoppers.

The same applies to the undercarriage work. In other words, when the operation of the air pressure pump is stopped, the air opening / closing stopper is opened, and the air suction / exhaust hoses 33a, 33b, 34a, 34b communicate with the outside air, and the air in the airtight chambers 16d, 16e, 17d, 17e is released. The water can be quickly discharged to the outside through the supply / exhaust hoses 33a, 33b, 34a, 34b, while the water is opened through the water supply / drain pipes 37a, 37b, 38a, 38b. It flows into 16d, 16e, 17d, 17e.

In this case, the airtight chambers 16e and 17 having a small space volume are provided.
Water will be filled in e before the airtight chambers 16d and 17d having a large space volume.

Accordingly, the buoyancy on the rear side of the floats 16 and 17 becomes smaller than the buoyancy on the front side, and the buoy A is inclined forward and backward and low and tilted in the front-rear direction. The inclination also acts as a force that suppresses or absorbs the inclination of the pontoon A in the left-right direction, so that it is possible to reliably prevent the pontoon A from overturning when the undercarriage is mounted. Also,
Even when the vehicle does not overturn, the inclination in the left-right direction can be effectively suppressed, so that the passenger does not have a sense of crisis.

Thereafter, the airtight chambers 16d and 17d having a large space volume are provided.
Floats 16,1 are completely filled with water.
The front of 7 also goes down, and floats 16 and 17 are horizontal.
Finally, the undercarriage operation is completed by closing the air switchgear and the water switchgear.

On the floating platform A described above, the floats 16,1
7, the mounting positions of the bulkheads 8,9, i.e., the front airtight chambers 16d, 17d
It is preferable that the ratio of the lengths of the rear airtight chambers 16e and 17e be 1.1 to 1.3: 1. When it is smaller than 1.1, the inclination to the left and right becomes large as in the case where the bulkheads 8 and 9 are provided in the center of the floats 16 and 17, while when it is larger than 1.3, the inclination to the front and rear is excessively steep. This will give the passengers a sense of crisis.

Further, in the case of the present embodiment, the use of the floats 16 and 17 having the above-mentioned non-uniformly divided structure makes it possible to reliably prevent inclination in the left-right direction.
When designing the space volume of 16, 17, it is only necessary to consider the buoyancy force for the upper rack, and it is almost unnecessary to consider the buoyancy force for preventing such inclination, so make the floats 16, 17 compact. The floats 16 and 17 can be manufactured inexpensively by reducing the number of manufacturing steps, and the economical efficiency of the floating platform C can be remarkably improved.

The case where the floats 16 and 17 have the non-equally divided structure has been described above.
It can be provided at the center of 16,17.

Next, in order to support the front and rear portions of the small boat B, bottom contact plates 5 provided at the front and rear of the loading platform 10 are provided.
The configuration of 0,51 will be described.

As shown in FIG. 1, the ship bottom contact plate 50 is attached to the front of the vertically long frame members 13, 14 of the loading platform 10, and is substantially shown in FIGS. 1, 3, and 5. As described above, a pair of abutting plate bodies 50a, 50b each having a V-shape,
The guide stays 50c and 50d are slidably mounted along the shaft, and side stoppers 50g and 50h.

Therefore, by fixing the contact plate main bodies 50a and 50b at arbitrary positions, the small boat B can be guided to an appropriate position from the beginning and then fixed.

In FIG. 1, guide members 55 and 56 are provided on the rear floats 16 and 17, respectively. The guide members 55 and 56 can protrude upward from the surface of the water at the time of lifting, so that the small boat B can be placed at a suitable position. It is provided for fixing with a cord (not shown).

FIG. 5 shows another embodiment of the floating dock A according to the present invention.

In this embodiment, as shown in FIG.
A fixed float depth adjusting mechanism 57 is provided in place of the buoyancy buoy 25 and the like.

That is, the float depth adjusting mechanism 57
Steps 57c for getting on and off the hull B are mounted on the floats 16 and 17 via the support legs 57d, and
A buoyant body storage space is formed between the upper surfaces of the floats 16 and 17 and the shoulders 57c, and a buoyant body 57b such as styrene foam can be freely inserted and removed in the storage space in multiple stages.

According to the above-described configuration, accurate depth adjustment can be achieved simply by replacing an arbitrary number of buoyant bodies 57b in the buoyant body storage space. Further, it is not necessary to use a ladder for getting on and off the hull B as in the conventional case, and it is possible to raise and lower the load from the stable tread 57c and to get on and off the personnel, and the rigging such as the float 25 is not necessary.

Further, as shown in FIG.
In the case of a settlement of 7, boarding from the floating platform A to the small vessel B is
Although it is impossible due to insufficient buoyancy, in FIG. 5, a sufficient buoyancy is obtained structurally, so that a person can get on the tether 57c, it is possible to easily board from the buoy A, and handling is large. Benefits are obtained.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the structures described in the above embodiments. For example, the present applicant previously filed a patent application. The float structure according to the present invention can be suitably used for the three-float floating berth and the four-float floating berth disclosed in Japanese Patent Laid-Open No. 5-9422.
