本発明に係る浮体装置の実施の形態について図1乃至図8に基づき説明する。なお、この実施の形態によりこの発明が限定されるものではない。 An embodiment of the floating device according to the present invention will be described with reference to FIGS. 1 to 8. The present invention is not limited to this embodiment.

(第1の実施形態)
第1の実施形態について、図1乃至図3に基づき説明する。まず、図1の斜視図を用いて浮体装置1の外観を説明する。図1において、本実施の形態の浮体装置1は、2個の浮体11からなる浮体部10と、浮体11の天面(図1のX方向とZ方向で形成されている面の内、上側の面。)に取り付けられている吊り下げ部20と、浮体11の短手側の側面(図1のZ方向とY方向で形成されている側面、以下、短手面と略す。)に設けられている2個の上側車輪部材31と2個の下側車輪部材32からなる車輪部30により構成されている。
(First Embodiment)
The first embodiment will be described with reference to FIGS. 1 to 3. First, the appearance of the floating device 1 will be described with reference to the perspective view of FIG. In FIG. 1, the floating body device 1 of the present embodiment has a floating body portion 10 composed of two floating bodies 11 and a top surface of the floating body 11 (upper side of the surfaces formed in the X and Z directions of FIG. 1). 20 and the side surface of the floating body 11 on the short side (the side surface formed in the Z direction and the Y direction in FIG. 1, hereinafter abbreviated as the short side). It is composed of a wheel portion 30 composed of two upper wheel members 31 and two lower wheel members 32.

2個の浮体11は、強化プラスチック(FRP)、木材や金属板で中空の水密性を有した箱状に形成されている。浮体11の外観は細長い略直方体で、水平方向の長さ(X方向)が、水平方向の幅(Z方向)の約12〜20倍であり、垂直方向の高さ(Y方向)が、水平方向の幅の2〜3倍になる様に形成されている。吊り下げる船の大きさや重さ、船台の大きさや水深により異なるが、本実施形態においては、水平方向の長さを約16メートル、水平方向の幅を約1メートル、高さを約2.4メートルとしている。 The two floating bodies 11 are made of reinforced plastic (FRP), wood or a metal plate, and are formed in a hollow, watertight box shape. The appearance of the floating body 11 is an elongated substantially rectangular body, the length in the horizontal direction (X direction) is about 12 to 20 times the width in the horizontal direction (Z direction), and the height in the vertical direction (Y direction) is horizontal. It is formed so as to be 2 to 3 times the width in the direction. Although it depends on the size and weight of the suspended ship, the size of the slipway and the water depth, in this embodiment, the horizontal length is about 16 meters, the horizontal width is about 1 meter, and the height is about 2.4. It is set to meters.

2個の浮体11は、長手側の側面(図1のX方向とY方向で形成されている側面、以下、長手面と略す。)を向かい合わせて、略平行になる様に吊り下げ部20により固定されることで、浮体部10となっている。 The two floating bodies 11 are suspended so that the side surfaces on the longitudinal side (side surfaces formed in the X and Y directions in FIG. 1, hereinafter abbreviated as the longitudinal surface) face each other and are substantially parallel to each other. By being fixed by, it becomes a floating body portion 10.

吊り下げ部20は、2個の浮体10の天面の略中央から、天面に対して垂直に設けられている柱部材21と、2本の柱部材21の夫々の上端に渡された梁部材22と、梁部材22に設けられた、2個の定滑車23と、柱部材21夫々の設けられた巻き上げ機24と、定滑車23と巻き上げ機24に通されたロープやワイヤー等の索状物25の張力を受けて上下に移動する動滑車26と、動滑車26に吊り下げられたベルト27から構成されている。 The hanging portion 20 is a beam passed from substantially the center of the top surfaces of the two floating bodies 10 to the upper ends of the pillar members 21 provided perpendicular to the top surfaces and the upper ends of the two pillar members 21. A member 22, two fixed pulleys 23 provided on the beam member 22, a hoisting machine 24 provided with each of the pillar members 21, and a rope, a wire, or the like passed through the fixed pulley 23 and the hoisting machine 24. It is composed of a moving pulley 26 that moves up and down under the tension of the object 25, and a belt 27 suspended from the moving pulley 26.

なお、柱部材21と梁部材22については、金属製のH鋼、角パイプ、丸パイプ等で吊り下げられる船の重量に合わせた強度を持つ材料で、形成されている。柱部材21については、浮体11と接合する側に筋交いとして、柱部材と浮体との関係強度を維持するための補強部材28が設けられている。補強材28は、本実施形態においては、金属製の棒としているが、ワイヤー、ターンバックル(引締金具)や、直角三角形の金属板等にしても良い。 The pillar member 21 and the beam member 22 are made of a material having a strength corresponding to the weight of the ship suspended by metal H-steel, a square pipe, a round pipe, or the like. The column member 21 is provided with a reinforcing member 28 for maintaining the strength of the relationship between the column member and the floating body as a brace on the side where the column member 21 is joined to the floating body 11. In the present embodiment, the reinforcing material 28 is a metal rod, but a wire, a turnbuckle (tightening metal fitting), a right-angled triangular metal plate, or the like may be used.

ベルト27は、吊り下げられる船に外面に傷を付けにくくするためのものであり、船の外面に接する付近の梁部材から下に垂れた「略U字状」になる範囲としている。また、巻き上げ機24については、手動又は電動等を吊り下げ対象の船の大きさにより適宜選択している。 The belt 27 is intended to prevent the outer surface of the suspended ship from being scratched, and has a range of a "substantially U-shaped" hanging downward from a beam member in the vicinity of contact with the outer surface of the ship. Further, as for the hoisting machine 24, manual or electric or the like is appropriately selected depending on the size of the ship to be suspended.

車輪部30は、後述する船台の上部側に接地させる2個の上側車輪部材31と、船台の下部側に接地させる2個の下側車輪部材32から構成されている。上側車輪部材31は、車輪と前記車輪を回動自在に軸支する車軸と、前記の車軸の両端を支持して浮体11と接続する支持金具とで構成されている。そして、上側車輪部材31は、各々の浮体11の短手面の下部から、車輪を側方に突き出す様に取り付けられている。 The wheel portion 30 is composed of two upper wheel members 31 that are grounded on the upper side of the slipway, which will be described later, and two lower wheel members 32 that are grounded on the lower side of the slipway. The upper wheel member 31 is composed of a wheel, an axle that rotatably supports the wheel, and a support metal fitting that supports both ends of the axle and connects to the floating body 11. The upper wheel member 31 is attached so as to project the wheel sideways from the lower part of the short side of each floating body 11.

また、上側車輪部材31の車輪の接地面は、浮体11の底面(図1のX方向とZ方向で形成されている面の内、下側の面。)と略同じ面を形成する様に取り付けられている。そのため、斜面である船台に浮体装置1が水平に置かれている場合には、浮体装置1の底面と船台の表面が接触することはなく、上側車輪部材31は浮体装置1の船台上での移動手段としての機能が発揮できる。 Further, the ground contact surface of the wheel of the upper wheel member 31 forms substantially the same surface as the bottom surface of the floating body 11 (the lower surface among the surfaces formed in the X and Z directions in FIG. 1). It is attached. Therefore, when the floating device 1 is placed horizontally on the slipway on the slope, the bottom surface of the floating device 1 does not come into contact with the surface of the slipway, and the upper wheel member 31 is placed on the slipway of the floating device 1. It can function as a means of transportation.

下側車輪部材32は、車輪と前記車輪を回動自在に軸支する車軸と、前記の車軸の両端を支持する第一の支持金具と、前記第一の支持金具に軸支すると同時に浮体11と接続する第二の支持金具とで構成されている。第一の支持金具に第二の支持金具が軸支することで、下側車輪部材32は角度を変化することができる。 The lower wheel member 32 includes a wheel and an axle that rotatably supports the wheel, a first support metal fitting that supports both ends of the axle, and a floating body 11 that is axially supported by the first support metal fitting. It is composed of a second support bracket to be connected to. The angle of the lower wheel member 32 can be changed by pivotally supporting the second support metal fitting to the first support metal fitting.

下側車輪部材32の角度の変化とは、各々浮体11の短手面の下部から、車輪を側方に突き出した状態の下側車輪部材32a(図1において、手前側の浮体11に図示している状態)と、折り曲げた状態で、車輪を下方向かって突き出す状態の下側車輪部材32b(図1において、奥側の浮体11に図示している状態)との2つの状態である。なお、下側車輪部材32の2つの形態については、固定ピンを差し込むことで、その状態を固定することを可能な様にしてある。 The change in the angle of the lower wheel member 32 means that the lower wheel member 32a (in FIG. 1, the front side floating body 11 is shown) in a state where the wheels are projected sideways from the lower part of the short side of the floating body 11. The lower wheel member 32b (the state shown in the floating body 11 on the back side in FIG. 1) in a state in which the wheel is projected downward in the bent state. Regarding the two forms of the lower wheel member 32, the state can be fixed by inserting a fixing pin.

また、下側車輪部材32については、車輪を下方に突き出す状態の下側車輪部材32bの場合に、船台7の傾斜角度に対して、車輪の接地位置が、浮体装置1が水平になる様な位置にしてなる様に取り付けられている。よって、下側車輪部材32bの場合には、船台7上における浮体装置1の略水平(水面に対して平行)になる移動手段として機能する。 Regarding the lower wheel member 32, in the case of the lower wheel member 32b in a state where the wheels are projected downward, the ground contact position of the wheels is such that the floating body device 1 is horizontal with respect to the inclination angle of the slipway 7. It is installed so that it is in the position. Therefore, in the case of the lower wheel member 32b, it functions as a means of moving the floating body device 1 on the slipway 7 so as to be substantially horizontal (parallel to the water surface).

なお、上側車輪部材31と下側車輪部材32を浮体11の底面に取り付けても、船台7からの進水や、船台7への陸揚げは可能である。しかしながら、上側車輪部材31と下側車輪部材32(特には32aの場合)が浮体11の短手面の下部に取り付けられ、浮体装置1の底面に取り付けられてないことにより、以下の様に働く。 Even if the upper wheel member 31 and the lower wheel member 32 are attached to the bottom surface of the floating body 11, the launching from the slipway 7 and the landing on the slipway 7 are possible. However, since the upper wheel member 31 and the lower wheel member 32 (particularly in the case of 32a) are attached to the lower part of the short side of the floating body 11 and not attached to the bottom surface of the floating body device 1, they work as follows. ..

浮体11の短手面の下部に上側車輪部材31と下側車輪部材32aが設けられていることにより、浮体11を岩や岸壁から守るダンパーとなる。また、浮体11の下面に車輪がないので、浮体装置を曳航する場合に水の抵抗が少なくなり、水深が浅い箇所でも入り安く、水中の水底の岩や水中に投棄されている人工物等により底面の車輪が破損することはない。さらには、上側車輪部材31と下側車輪部材32aは、側面にあるので、メンテナンスが容易になる。 Since the upper wheel member 31 and the lower wheel member 32a are provided below the short surface of the floating body 11, it becomes a damper that protects the floating body 11 from rocks and quays. Further, since there are no wheels on the lower surface of the floating body 11, the resistance of water is reduced when towing the floating body device, it is easy to enter even in a shallow water depth, and due to rocks on the bottom of the water or artificial objects dumped in the water. The wheels on the bottom will not be damaged. Further, since the upper wheel member 31 and the lower wheel member 32a are on the side surfaces, maintenance is facilitated.

図2を用いて、浮体装置1の陸揚げ方法について説明する。図2(a)は、造船された船5が2個の台車6に載せられて船台7の水面8よりも高い箇所に有る状態を示している。 The landing method of the floating body device 1 will be described with reference to FIG. FIG. 2A shows a state in which the built ship 5 is mounted on two carriages 6 and is located at a position higher than the water surface 8 of the slipway 7.

ここで、図2及び図3の船台7について説明する。船台7は、海、湖又は河等に面した所定の角度(一般的には、8〜5度)を設けた斜面である。また、船台7の表面は、船5を載せた台車6が下架時に転がり易い様に、レールが敷設されている。さらに、船台7は、造船作業にも用いられるので、作業が楽に行える様に船台7の表面はコンクリートで舗装されている。 Here, the slipway 7 of FIGS. 2 and 3 will be described. The slipway 7 is a slope provided with a predetermined angle (generally 8 to 5 degrees) facing the sea, lake, river, or the like. Further, on the surface of the slipway 7, rails are laid so that the dolly 6 on which the ship 5 is mounted can easily roll when lowered. Further, since the slipway 7 is also used for shipbuilding work, the surface of the slipway 7 is paved with concrete so that the work can be performed easily.

また、図2及び図3の船5について説明する。図示されている船5は、船体(水に浮く部分)のみを図示しており、船台7上で造船する場合には、船体上部の操舵室、船室や煙突、漁船であればマストや巻き上げ機等の漁業機械については、本実施形態の説明においては重要な部分ではないので省略している。さらに、船5については、図2において作図上も船首の部分を一部省略している。 Further, the ship 5 of FIGS. 2 and 3 will be described. The ship 5 shown shows only the hull (the part that floats on the water), and when building on the slipway 7, the wheelhouse at the top of the hull, the cabin and chimney, and the mast and hoisting machine for fishing boats. Etc. are omitted because they are not important parts in the description of this embodiment. Further, with respect to the ship 5, a part of the bow part is omitted in the drawing in FIG.

船5の船体における船底は平らではなく、船首から船尾側の舵やスクリューの部分に向かって喫水(水面から船底までの距離)が深くなる形状となっている。なお、この船体における船底の形状は強化プラスチック製の高速漁船に多く用いられている。
以上の様な船台7の上に置かれている船5に対して、浮体装置1を船台7に陸揚げする方法を説明する。
The bottom of the hull of the ship 5 is not flat, and the draft (distance from the water surface to the bottom) becomes deeper from the bow to the rudder and screw on the stern side. The shape of the bottom of this hull is often used for high-speed fishing boats made of reinforced plastic.
A method of landing the floating device 1 on the slipway 7 with respect to the ship 5 placed on the slipway 7 as described above will be described.

図2(a)は、船5が置かれている船台7に対して、また、浮体装置1は、海、湖又は川等の水中に浮かんだ状態となっている。そして、浮体装置1を船台7に近づける場合には、浮体装置1の2個の浮体11の間に、船5の船尾に合わせて、船5を挟む様な位置に浮体装置1の位置を合わせて、浮体装置1を船台7に近づける。なお、船台7にレールがある場合には、レールを目印にしても良い。 FIG. 2A shows a state in which the slipway 7 on which the ship 5 is placed and the floating device 1 are floating in water such as the sea, a lake, or a river. Then, when the floating device 1 is brought closer to the slipway 7, the position of the floating device 1 is aligned between the two floating bodies 11 of the floating device 1 so as to sandwich the ship 5 in accordance with the stern of the ship 5. Then, the floating device 1 is brought closer to the slipway 7. If the slipway 7 has a rail, the rail may be used as a mark.

浮体装置1を船台7に近づけると、浮体装置1は、まだ水中にはあるが、船台7の斜面に上側車輪部材31の車輪が接触する又は乗り上げると、図2(b)状態になる。なお、図2(b)において、浮体装置1の下側車輪部材32は、車輪を下方向かって突き出す状態の下側車輪部材32bにしてある。そのため、浮体装置1が、水中にまだ浸かった状態で、船台7の斜面上にはあれば、水面の波などによる揺らぎによっては、船台7の斜面上に下側車輪部材32(32b)の車輪が触れる状態にもなっている。 When the floating device 1 is brought close to the slipway 7, the floating device 1 is still in the water, but when the wheels of the upper wheel member 31 come into contact with or ride on the slope of the slipway 7, the state shown in FIG. 2B is obtained. In FIG. 2B, the lower wheel member 32 of the floating device 1 is a lower wheel member 32b in a state where the wheels are projected downward. Therefore, if the floating device 1 is still submerged in water and is on the slope of the slipway 7, the wheels of the lower wheel member 32 (32b) may be placed on the slope of the slipway 7 depending on fluctuations due to waves on the water surface. Is also in a state of being touched.

図2(b)の状態から、さらに、外部から巻き上げ機や人力等によって浮体装置1に力を加え、浮体装置1を船台7の斜面の陸方向に押し上げる(引き上げる)と、図2(c)の状態になる。なお、図2(c)の状態になった浮体装置1は、船5の船尾側から、2個の浮体11の間に挟む様な位置にして押し上げられていることになる。 From the state shown in FIG. 2B, when a force is further applied to the floating device 1 from the outside by a hoisting machine, human power, etc., and the floating device 1 is pushed up (pulled up) in the land direction on the slope of the slipway 7, FIG. It becomes the state of. The floating device 1 in the state shown in FIG. 2C is pushed up from the stern side of the ship 5 so as to be sandwiched between the two floating bodies 11.

図2(c)の状態の船5と浮体装置1の位置関係をさらに説明すると、浮体装置1の吊り下げ部20の両側の柱部材21の位置と、船5のスクリュー5aと船5の船底の上部の空間(図2(a)、(b)参照。)の位置が並ぶ様にする。この位置にまで、浮体装置1を押し上げると、浮体装置1を船台7上に車止め9により固定する。その後、船5のスクリュー5aと船5の船底の上部の空間に吊り下げ部20のベルト27(図2においては、ベルト27の図示を省略。図1を参照。)を通す。なお、ベルト27については、船5のスクリュー5aと船5の船底の上部の空間に通しているたけで、吊り下げるまでは行っていない。 To further explain the positional relationship between the ship 5 and the floating device 1 in the state of FIG. 2C, the positions of the pillar members 21 on both sides of the hanging portion 20 of the floating device 1, the screw 5a of the ship 5, and the bottom of the ship 5 The positions of the space above (see FIGS. 2 (a) and 2 (b)) should be aligned. When the floating device 1 is pushed up to this position, the floating device 1 is fixed on the slipway 7 by a bollard 9. After that, the belt 27 of the hanging portion 20 (the belt 27 is not shown in FIG. 2; see FIG. 1) is passed through the space above the screw 5a of the ship 5 and the bottom of the ship 5. It should be noted that the belt 27 is only passed through the space above the screw 5a of the ship 5 and the bottom of the ship 5, and is not suspended until it is hung.

浮体装置1を陸揚げせず、船台7から下架させた船5の水中にある船5のスクリュー5aと船5の船底の上部の空間にベルト27を通すことも可能である。しかしなから、ベルトを通す作業が、水中になることや、船尾が水底に衝突しないことを確認しながら、下架させる必要があることから、船台7に浮体装置1を陸揚げした方が良い。 It is also possible to pass the belt 27 through the screw 5a of the ship 5 and the space above the bottom of the ship 5 underwater of the ship 5 suspended from the slipway 7 without landing the floating device 1. However, since it is necessary to lower the belt while confirming that the work of passing the belt is underwater and that the stern does not collide with the bottom of the water, it is better to land the floating device 1 on the slipway 7.

図3を用いて、浮体装置1で挟んだ船5を下架する方法について説明する。 A method of suspending the ship 5 sandwiched between the floating device 1 will be described with reference to FIG.

図2(c)の、船5のスクリュー5aと船5の船底の上部の空間(図2(a)、(b)参照。)に吊り下げ部20のベルト27(図3においては、巻きベルト27の図示を省略。図1を参照。)に余裕を与えて通した状態で、図2(c)の浮体装置1と船5の位置関係を保ちながら、船台7の斜面を下方に向かって移動させる。そして、浮体装置1が、水面8に浮かぶ場所まで、船台7の斜面の下方に移動させた状態が、図3(a)である。 In FIG. 2 (c), the belt 27 of the hanging portion 20 (in FIG. 3, the winding belt) in the space above the screw 5a of the ship 5 and the bottom of the ship 5 (see FIGS. 2 (a) and 2 (b)). 27 is omitted. (See FIG. 1) with a margin, and while maintaining the positional relationship between the floating device 1 and the ship 5 in FIG. 2 (c), the slope of the slipway 7 is directed downward. Move. FIG. 3A shows a state in which the floating device 1 is moved below the slope of the slipway 7 to a place where it floats on the water surface 8.

図3(a)の状態で、浮体装置1の巻き上げ機24で索状物25を巻き上げて(図3においては、巻き上げ機24と索状物25の図示を省略。図1を参照。)、ベルト27を上方に引き上げて船5を吊り上げると、図3(b)の状態になる。 In the state of FIG. 3A, the cord 25 is wound by the hoist 24 of the floating device 1 (in FIG. 3, the hoist 24 and the chord 25 are not shown. See FIG. 1). When the belt 27 is pulled upward and the ship 5 is lifted, the state shown in FIG. 3B is obtained.

図3(b)において、浮体装置1は、浮体装置1の浮力で、船5の喫水線が深い船尾側に適当な水深まで吊り上げている。なお、下側車輪部材32は、車輪を下方に突き出した状態の下側車輪部材32bであるので、下側車輪部材32bが船台7上にある時は、下側車輪部材32bの車輪が船台7に接触するので、浮体装置1の浮力によらず、船5を吊り上げることも可能となる。 In FIG. 3B, the floating body device 1 is lifted to an appropriate water depth on the stern side where the waterline of the ship 5 is deep by the buoyancy of the floating body device 1. Since the lower wheel member 32 is a lower wheel member 32b in a state where the wheels are projected downward, when the lower wheel member 32b is on the slipway 7, the wheels of the lower wheel member 32b are on the slipway 7. Therefore, it is possible to lift the ship 5 regardless of the buoyancy of the floating device 1.

図3(c)は、図3(b)の状態から、船5を浮体装置1で吊り上げて、船台7から離れて、海、湖又は河等の水面まで出た状態の図である。船5の喫水線が深い船尾側は、浮体装置1により吊り上げられていることにより、浚渫が難しい海、湖又は河等の浅い水域でも船5を移動させることができる。 FIG. 3 (c) is a diagram showing a state in which the ship 5 is lifted by the floating device 1 from the state of FIG. 3 (b), separated from the slipway 7, and reaches the surface of the sea, lake, river, or the like. Since the stern side where the waterline of the ship 5 is deep is lifted by the floating body device 1, the ship 5 can be moved even in a shallow water area such as a sea, a lake, or a river where dredging is difficult.

また、図3(c)において、下側車輪部材32は、浮体装置1が浮力のみで良い場合であるので、車輪を側方に突き出した状態の下側車輪部材32aに角度を変えている。そのため、下側車輪部材32が浅い水域でも邪魔になることはない。また、船5を吊り下げた浮体装置1をタグボート(引船、曳船又は押船)で、曳航する場合でも、抵抗になることはない。 Further, in FIG. 3C, since the floating body device 1 only needs buoyancy, the angle of the lower wheel member 32 is changed to the lower wheel member 32a in a state where the wheels are projected sideways. Therefore, the lower wheel member 32 does not get in the way even in a shallow water area. Further, even when the floating device 1 in which the ship 5 is suspended is towed by a tugboat (towing ship, towing ship or pushing ship), there is no resistance.

以上、浮体装置1で、船5を下架する場合を説明したが、浮体装置1で船5を上架する場合には逆の手順で行えば良い。なお、船5の上架の場合には、船5が船台7に載った時点で、浮体装置1による吊り上げを止め、浮体装置1を船台7に陸揚げする必要はない。 The case where the ship 5 is mounted on the floating device 1 has been described above, but the reverse procedure may be performed when the ship 5 is mounted on the floating device 1. In the case of an overhanging ship 5, it is not necessary to stop the lifting by the floating device 1 and land the floating device 1 on the slipway 7 when the ship 5 is placed on the slipway 7.

(第2の実施形態)
第2の実施形態について、図4乃至図8に基づき説明する。まず、図4の斜視図を用いて浮体装置2の概要を説明する。図4において、本実施の形態の浮体装置2は、2個の浮体11aからなる浮体部10aと、浮体11aの天面(図4のX方向とZ方向で形成されている面の内、上側の面。)に取り付けられている吊り下げ部20と、浮体11aの短手側の側面(図4のZ方向とY方向で形成されている側面、以下、短手面と略す。以下、短手面と略す。)に設けられている2個の上側車輪部材31からなる車輪部30aにより構成されている。
(Second Embodiment)
The second embodiment will be described with reference to FIGS. 4 to 8. First, the outline of the floating body device 2 will be described with reference to the perspective view of FIG. In FIG. 4, the floating device 2 of the present embodiment has a floating body portion 10a composed of two floating bodies 11a and a top surface of the floating body 11a (the upper side of the surfaces formed in the X and Z directions of FIG. 4). 20 and the side surface of the floating body 11a on the short side (the side surface formed in the Z direction and the Y direction in FIG. 4, hereinafter abbreviated as the short side). It is composed of a wheel portion 30a composed of two upper wheel members 31 provided on a hand surface (abbreviated as a hand surface).

2個の浮体11aは、強化プラスチック(FRP)、木材や金属板で中空の水密性を有した箱状に形成されている。浮体11aの外観は細長い略直方体で、水平方向の長さ(X方向)が、水平方向の幅(Z方向向)の約12〜20倍であり、垂直方向の高さ(Y方向)が、水平方向の幅の2〜3倍になる様に形成されている。 The two floating bodies 11a are made of reinforced plastic (FRP), wood or a metal plate, and are formed in a hollow, watertight box shape. The appearance of the floating body 11a is an elongated substantially rectangular body, the length in the horizontal direction (X direction) is about 12 to 20 times the width in the horizontal direction (Z direction), and the height in the vertical direction (Y direction) is. It is formed so as to be 2 to 3 times the width in the horizontal direction.

吊り下げる船の大きさや重さ、船台の大きさや水深により異なるが、本実施形態においては、水平方向の長さを約16メートル、水平方向の幅を約1メートル、高さを約2.4メートルとしている。 Although it depends on the size and weight of the suspended ship, the size of the slipway and the water depth, in this embodiment, the horizontal length is about 16 meters, the horizontal width is about 1 meter, and the height is about 2.4. It is set to meters.

2個の浮体11aは、長手側の側面(図4のX方向とY方向で形成されている側面、以下、長手面と略す。)を向かい合わせて、略平行になる様に吊り下げ部20により固定されることで、浮体部10aとなっている。 The two floating bodies 11a are suspended so that the side surfaces on the longitudinal side (side surfaces formed in the X and Y directions in FIG. 4, hereinafter abbreviated as the longitudinal surface) face each other and are substantially parallel to each other. By being fixed by, it becomes a floating body portion 10a.

図5は浮体11aの内部の構造の断面図(図4のA―Aにおける断面図)である。浮体11a内部の空間は長手方向(X方向)に中央部で二つの空間に分割する隔壁12が設けられている。そして、隔壁12により、浮体11aの内部には、独立して水密性の保たれた第一の空間13と、第二の空間14とを有している。また、浮体11aの天面側の両端近傍には、第一の空間13と第二の空間14の夫々に、第一の空間13と第二の空間14の夫々に通じる蓋15が設けられている。図5においては、第一の空間13の蓋15は閉められた状態として、第二の空間14の蓋15は開けられた状態として図示している。 FIG. 5 is a cross-sectional view of the internal structure of the floating body 11a (cross-sectional view taken along the line AA of FIG. 4). The space inside the floating body 11a is provided with a partition wall 12 that divides the space inside the floating body 11a into two spaces at the center in the longitudinal direction (X direction). The partition wall 12 has a first space 13 and a second space 14 that are independently maintained in watertightness inside the floating body 11a. Further, in the vicinity of both ends on the top surface side of the floating body 11a, lids 15 communicating with the first space 13 and the second space 14 are provided in each of the first space 13 and the second space 14. There is. In FIG. 5, the lid 15 of the first space 13 is shown as a closed state, and the lid 15 of the second space 14 is shown as an open state.

吊り下げ部20は、2個の浮体11aの天面の略中央に取り付けられている。吊り下げ部20については、第1の実施形態と同一であり、同一の符号を附して説明を省略する。 The hanging portion 20 is attached to substantially the center of the top surface of the two floating bodies 11a. The hanging portion 20 is the same as that of the first embodiment, and the same reference numerals are given and the description thereof will be omitted.

車輪部30aは、第1の実施形態と同様の2個の上側車輪部材31のみが、浮体11aの短手面の下部から、車輪を側方に突き出す様に取り付けられている。よって、上側車輪部材31の構造は省略する。 The wheel portion 30a is attached so that only the two upper wheel members 31, which are the same as those in the first embodiment, project the wheels sideways from the lower part of the short side of the floating body 11a. Therefore, the structure of the upper wheel member 31 is omitted.

また、上側車輪部材31の車輪の接地面は、浮体11の底面(図4のX方向とZ方向で形成されている面の内、下側の面。)と略同じ面を形成する様に取り付けられている。そのため、斜面である船台に浮体装置2が水平に置かれている場合には、浮体装置2の底面と船台の表面が接触することはなく、上側車輪部材31は浮体装置2の船台上での移動手段としての機能が発揮できる。 Further, the ground contact surface of the wheel of the upper wheel member 31 forms substantially the same surface as the bottom surface of the floating body 11 (the lower surface among the surfaces formed in the X and Z directions in FIG. 4). It is attached. Therefore, when the floating device 2 is placed horizontally on the slipway on the slope, the bottom surface of the floating device 2 does not come into contact with the surface of the slipway, and the upper wheel member 31 is placed on the slipway of the floating device 2. It can function as a means of transportation.

なお、上側車輪部材31を浮体11aの底面に取り付けても、船台7からの進水や、船台7への設置は可能である。しかしながら、上側車輪部材31が浮体11aの短手面の下部に取り付けられ、浮体装置2の底面に取り付けられてないことにより、以下の様に働く。 Even if the upper wheel member 31 is attached to the bottom surface of the floating body 11a, it can be launched from the slipway 7 or installed on the slipway 7. However, since the upper wheel member 31 is attached to the lower part of the short side of the floating body 11a and is not attached to the bottom surface of the floating body device 2, it works as follows.

浮体11aの短手面の下部に上側車輪部材31が設けられていることにより、浮体11aを岩や岸壁から守るダンパーとなる。また、浮体11aの下面に車輪がないので、浮体装置を曳航する場合に水の抵抗が少なくなり、水深が浅い箇所でも入り安く、水中の水底の岩や水中に投棄されている人工物等により底面の車輪が破損することはない。さらには、上側車輪部材31は、側面にあるので、メンテナンスが容易になる。 Since the upper wheel member 31 is provided below the short surface of the floating body 11a, it becomes a damper that protects the floating body 11a from rocks and quays. In addition, since there are no wheels on the lower surface of the floating body 11a, the resistance of water is reduced when towing the floating body device, it is easy to enter even in shallow water, and due to rocks on the bottom of the water or artificial objects dumped in the water. The wheels on the bottom will not be damaged. Further, since the upper wheel member 31 is on the side surface, maintenance is facilitated.

図6と図7を用いて、浮体装置2を船台7に設置する方法について説明する。図6(a)は、造船された船5が2個の台車6に載せられて船台7の水面8よりも上の箇所に有る状態を示している。なお、船5と船台7については、第1の実施形態と同様であるので説明を省略する。 A method of installing the floating device 2 on the slipway 7 will be described with reference to FIGS. 6 and 7. FIG. 6A shows a state in which the built ship 5 is mounted on two carriages 6 and is located above the water surface 8 of the slipway 7. Since the ship 5 and the slipway 7 are the same as those in the first embodiment, the description thereof will be omitted.

図6(a)の第1の実施形態と同様の船5と船台7であるとして、図6(a)は、船5が置かれている船台7に対して、また、浮体装置2は、海、湖又は川等の水中に浮かんだ状態となっている。そして、浮体装置2を船台7に近づける場合には、浮体装置2の2個の浮体11aの間に、船5の船尾に合わせて、船5を挟む様な位置に浮体装置2の位置を合わせて、浮体装置2を船台7に近づける。なお、船台7にレールがある場合には、レールを目印にしても良い。 Assuming that the ship 5 and the slipway 7 are the same as those in the first embodiment of FIG. 6 (a), FIG. It is floating in the water such as the sea, lake or river. Then, when the floating device 2 is brought closer to the slipway 7, the position of the floating device 2 is aligned between the two floating bodies 11a of the floating device 2 so as to sandwich the ship 5 in accordance with the stern of the ship 5. Then, the floating device 2 is brought closer to the slipway 7. If the slipway 7 has a rail, the rail may be used as a mark.

浮体装置2を船台7に近づけると、浮体装置2は、まだ水中にはあるが、船台7の斜面に上側車輪部材31の車輪が接触する又は乗り上げると、図6(b)状態になる。 When the floating device 2 is brought closer to the slipway 7, the floating device 2 is still in the water, but when the wheels of the upper wheel member 31 come into contact with or ride on the slope of the slipway 7, the state shown in FIG. 6B is obtained.

次に図6(b)の状態から、外部の巻き上げ機や人力によって、浮体装置2を船台7の斜面の陸方向に押し上げる(引き上げる)と、図6(c)の状態となる。この場合、2個の上側車輪部材31の回転によって(浮体装置2の底面と船台7と接触しない限り)船台7上に浮体装置2は、船台7を昇る様に、言い換えるならば上側車輪部材31を上方向に向けて傾きながら押し上げられることになる。 Next, from the state shown in FIG. 6B, when the floating device 2 is pushed up (pulled up) in the land direction on the slope of the slipway 7 by an external hoisting machine or human power, the state shown in FIG. 6C is obtained. In this case, the rotation of the two upper wheel members 31 causes the floating device 2 to rise on the slipway 7 (unless the bottom surface of the floating device 2 comes into contact with the slipway 7), in other words, the upper wheel member 31. Will be pushed up while tilting upward.

図6(c)の状態で、第二の空間14の蓋15を開け、第二の空間14に浮体11aの周囲の水を水中ポンプから連通したホースで注水して、浮体装置2を船台7上に設置させた状態が図7(a)である。図7において、第二の空間14の網掛けで示した箇所が注水された箇所として図示している。 In the state of FIG. 6C, the lid 15 of the second space 14 is opened, the water around the floating body 11a is injected into the second space 14 with a hose communicating with the submersible pump, and the floating body device 2 is mounted on the slipway 7. FIG. 7A shows a state in which the hose is installed above. In FIG. 7, the shaded portion of the second space 14 is illustrated as the injected portion.

なお、水中ポンプで第二の空間14に注水する場合には、浮体装置2の2個の浮体11aを同時に注水する。また、浮体装置2の2個の浮体11aの沈む速度についても、水中ポンプの流量を調整して同じ沈下速度になる様に注水する。浮体装置2の2個の浮体11aが傾くことによる、浮体装置2全体としての捻りが加わらない様にするためである。 When water is injected into the second space 14 by a submersible pump, the two floating bodies 11a of the floating body device 2 are injected at the same time. Further, with respect to the sinking speed of the two floating bodies 11a of the floating body device 2, water is injected so as to have the same sinking speed by adjusting the flow rate of the submersible pump. This is to prevent twisting of the floating body device 2 as a whole due to tilting of the two floating bodies 11a of the floating body device 2.

浮体装置2の2個の浮体11aの第二の空間14に同時に注水すると、浮体装置2は、第二の空間14側から船台7の上に設置(着地)する。なお、注水と排水作業が容易になるので、水面8に多く浸っていたる側の第二の空間14に注水するだけで良いが、潮の満ち引き等の影響を考えなければいけない場合には、第一の空間13にも注水しても良い。 When water is simultaneously injected into the second space 14 of the two floating bodies 11a of the floating body device 2, the floating body device 2 is installed (landed) on the slipway 7 from the second space 14 side. Since water injection and drainage work will be easier, it is sufficient to inject water into the second space 14 on the side that is heavily immersed in the water surface 8, but if you have to consider the effects of the ebb and flow of the tide, etc. Water may also be injected into the first space 13.

浮体装置2を船台7上に設置させた図7(a)状態で、台車6に載せた船5を船台7の斜面を緩やかに移動させながら、浮体装置2に近づける。そして、浮体装置2の2個の浮体11aの間に、船5を船尾側から差し込んで行く。最終的に船5は、浮体装置2の吊り下げ部20の両側の柱部材21の位置と、船5のスクリュー5aと船5の船底の上部の空間(図6、図7(a)参照。)船5のスクリュー5a上部の空間の位置が並ぶ位置にまで船5を移動させる。その船5を浮体装置2の浮体11aの間に移動させた状態が図7(b)である。 In the state of FIG. 7A in which the floating device 2 is installed on the slipway 7, the ship 5 mounted on the carriage 6 is brought closer to the floating device 2 while gently moving the slope of the slipway 7. Then, the ship 5 is inserted from the stern side between the two floating bodies 11a of the floating body device 2. Finally, in the ship 5, the positions of the pillar members 21 on both sides of the hanging portion 20 of the floating device 2 and the space above the screw 5a of the ship 5 and the bottom of the ship 5 (see FIGS. 6 and 7 (a)). ) Move the ship 5 to a position where the positions of the spaces above the screw 5a of the ship 5 are lined up. FIG. 7B shows a state in which the ship 5 is moved between the floating bodies 11a of the floating body device 2.

図7(b)に移動させた船5の台車は、車止めや台車のブレーキ装置で停車させる。その後、スクリュー5a上部の空間(図6、図7(a)参照。)に吊り下げ部20のベルト27(図7においては、ベルト27の図示を省略。図4を参照。)を通す。なお、ベルト27については、船5のスクリュー5aと船5の船底の上部の空間に通しているたけで、吊り下げるまでは行っていない。 The bogie of the ship 5 moved in FIG. 7B is stopped by a bollard or a brake device of the bogie. After that, the belt 27 of the hanging portion 20 (the belt 27 is not shown in FIG. 7; see FIG. 4) is passed through the space above the screw 5a (see FIGS. 6 and 7 (a)). It should be noted that the belt 27 is only passed through the space above the screw 5a of the ship 5 and the bottom of the ship 5, and is not suspended until it is hung.

図8を用いて、浮体装置2まで移動させた船5を下架する方法について説明する。 A method of suspending the ship 5 moved to the floating device 2 will be described with reference to FIG.

図7(c)の、船5のスクリュー5aと船5の船底の上部の空間(図6、図7(a)参照。)に吊り下げ部20のベルト27を通したままの状態(ベルト27には余裕を与えた状態)で、第二の空間14の蓋15を開け、第二の空間14の内部の水に水中ポンプを入れて浮体11aの外部に排水する。第二の空間14から排水して浮体装置2が水面8に浮かんだ状態が図8(a)である。 In the state of FIG. 7 (c), the belt 27 of the hanging portion 20 is still passed through the space above the screw 5a of the ship 5 and the bottom of the ship 5 (see FIGS. 6 and 7 (a)) (belt 27). The lid 15 of the second space 14 is opened, and a submersible pump is put into the water inside the second space 14 to drain the water to the outside of the floating body 11a. FIG. 8A shows a state in which the floating device 2 floats on the water surface 8 after draining from the second space 14.

水中ポンプで排水する場合には、浮体装置2の2個の浮体11aを同時にゆっくり浮かぶ様に水中ポンプの流量を調整して排水する。浮体装置2が傾いて、船5と接触しない様にすることや、浮体装置2全体としての捻りが加わらない様にするためである。 When draining with a submersible pump, the flow rate of the submersible pump is adjusted so that the two floating bodies 11a of the floating body device 2 float slowly at the same time. This is to prevent the floating body device 2 from tilting and coming into contact with the ship 5 and to prevent the floating body device 2 as a whole from being twisted.

図8(a)の状態で、浮体装置2の巻き上げ機24で索状物25を巻き上げてベルト27を上方に引き上げると(図8においては、巻き上げ機24、索状物25とベルト27の図示を省略。図4を参照。)、図8(b)の状態になる。図8(b)において、浮体装置2は、浮体装置2の浮力で、船5の喫水線が深い船尾側に適当な水深まで吊り上げている。 In the state of FIG. 8A, when the cord 25 is wound by the winding machine 24 of the floating device 2 and the belt 27 is pulled upward (in FIG. 8, the winding machine 24, the cord 25 and the belt 27 are illustrated). (Refer to FIG. 4), and the state shown in FIG. 8 (b) is obtained. In FIG. 8B, the floating body device 2 is lifted to an appropriate water depth on the stern side where the waterline of the ship 5 is deep by the buoyancy of the floating body device 2.

図8(c)は、図8(b)の状態から、船5を浮体装置2で吊り上げて、船台7から離れて、海、湖又は河等の水面まで出た状態の図である。船5の喫水線が深い船尾側は、浮体装置2により吊り上げられていることにより、浚渫が難しい海、湖又は河等の浅い水域でも船5を移動させることができる。 FIG. 8 (c) is a diagram showing a state in which the ship 5 is lifted by the floating device 2 from the state of FIG. 8 (b), separated from the slipway 7, and reaches the surface of the sea, lake, river, or the like. Since the stern side where the waterline of the ship 5 is deep is lifted by the floating body device 2, the ship 5 can be moved even in a shallow water area such as a sea, a lake or a river where dredging is difficult.

以上、浮体装置2で、船5を下架する場合を説明したが、浮体装置2で船5を上架する場合には逆の手順で行えば良い。 The case where the ship 5 is mounted by the floating device 2 has been described above, but the reverse procedure may be performed when the ship 5 is mounted by the floating device 2.

なお、本実施形態1の浮体装置1と、本実施形態2の浮体装置2が対象とする漁船は、沿岸から沖合で操業するもので、大型船舶と異なり、ベースラインとキール下面が交差し、船首尾喫水に著しい差があるイニシャルトリムを付けた船型が大半となっている。そして、船尾側の喫水が深いために、浅水域での航行に支障が出ると言う問題がある。 The floating device 1 of the first embodiment and the fishing boat targeted by the floating device 2 of the second embodiment operate offshore from the coast, and unlike large vessels, the baseline and the lower surface of the keel intersect. Most of the boats have initial trim, which has a significant difference in draft. And since the draft on the stern side is deep, there is a problem that navigation in shallow water is hindered.

また、船首側にバラストタンク等があれば、トリム調整することも一策ではあるが、建造船台からの下架は危険を伴うことになる。そのため、直接船尾を持ち上げる(吊上げる)方法が確実であり、更に左右舷のバランス(復原性)を安全に確保するためには、本実施形態1の浮体装置1と、本実施形態2の浮体装置2の様に、舷外に浮体11や浮体11aを備えた方が有効となる。 Also, if there is a ballast tank on the bow side, it is a good idea to adjust the trim, but the undercarriage from the slipway will be dangerous. Therefore, the method of directly lifting (lifting) the stern is reliable, and in order to safely secure the balance (stability) of the port side, the floating body device 1 of the present embodiment 1 and the floating body of the present embodiment 2 are used. It is more effective to provide the floating body 11 and the floating body 11a on the outer side as in the device 2.

以上、本発明について、第1〜第2の実施形態に基づき説明してきたが、本発明は何らこれらの実施形態の構成に限定するものではない。例えば、実施形態1の浮体11を実施形態2の浮体11aに変えて実施することや、浮体11、11aについても、短手面の形状を方形以外にも円形、楕円形や台形等にして実施することも可能である。また、車輪部30、30aについては、着脱式とする方法としても良い。 Although the present invention has been described above based on the first and second embodiments, the present invention is not limited to the configurations of these embodiments. For example, the floating body 11 of the first embodiment is changed to the floating body 11a of the second embodiment, and the floating bodies 11 and 11a are also implemented by changing the shape of the short side surface to a circular shape, an elliptical shape, a trapezoidal shape, or the like in addition to the square shape. It is also possible to do. Further, the wheels 30 and 30a may be detachable.

さらには、この発明は、これらに限定されるものではなく、特許請求の範囲に記載された発明とその均等の範囲を含むものである。
以下に、本件出願の特許請求の範囲に記載された発明を付記する。
