As shown in FIG. 3, the seat member 3 of this example has a pair of side frames 31 and 31 extending in parallel with each other and shorter than the side frame 31, and each end of these side frames 31 and 31 is formed. A pair of connecting frames 32, 32 to be connected are provided and formed in a rectangular frame shape. Further, the connecting frame 32 of this example has a V shape along the bottom of the onboard boat 2.

Further, a reinforcing frame 33 is bridged between the connecting frames 32 and 32 to increase the load strength of the seat member 3.

In addition, as shown in FIGS. 1, 2 and 3, a C-shaped pedestal portion 34 provided so as to project upward from the connecting frame 32 is provided at each connecting portion of the connecting frame 32 with the reinforcing frame 33. A cushion portion 35 formed of an elastic body such as rubber is provided on the upper surface of each pedestal portion 34. As a result, even if the mounted boat 2 is mounted on the seat member 3, the bottom of the mounted boat 2 is not damaged. Further, in this example, since the mounted boat 2 is supported at four points by the pedestals 34 and the cushion portions 35 provided at four positions of the connecting frame 32 having a shape along the bottom of the mounted boat 2, the mounted boat 2 is supported. Can be supported without backlash.

In the seat member 3 of this example shown in FIG. 3, two reinforcing frames 33 are provided, but the number of the reinforcing frames 33 is not particularly limited, and the seat member 3 has enough strength to support the mounted boat 2. If it is secured, the reinforcing frame 33 may be omitted.

Further, as shown in FIGS. 1 and 2, a dabit 4 is installed on the floor 10 of the accommodation recess R. The dabit 4 of this example includes a dabit frame 6, a dabit arm 7 that supports the dabit frame 6 and can swing the dabit frame 6 into and out of the accommodation recess R, and a hydraulic cylinder 8 as a drive source for driving the dabit arm 7. The seat member 3 is hung at four points in the front, rear, left and right via the wire rope W.

As shown in FIG. 3, the dabit frame 6 of this example includes a pair of short frames 11 and 11 extending in parallel with each other and a pair of longitudinal frames 12 provided so as to be bridged between the short frames 11 and 11. , 12 are provided and formed in a frame shape. Further, the dabit frame 6 of this example is provided at the top and bottom of FIG. 3, respectively, and the first reinforcing beam 22 which is diagonally bridged from each of the longitudinal frames 12 to the short frame 11 and is provided at the top and bottom of FIG. The second reinforcing beam 23 is provided so as to be bridged between the longitudinal frames 12 and 12, and the load strength of the dabit frame 6 is reinforced.

Further, as shown in FIG. 3, winches 5 and 5 are provided side by side on the outer side of the upper side of the drawing, which is connected to the longitudinal frames 12 and 12, of the short frame 11.

Further, on the inner side of each of the longitudinal frames 12 and 12, two sheaves 9 that can rotate in the same direction as the winch 5 are provided side by side at predetermined intervals along the longitudinal direction of the longitudinal frame 12.

Here, the winch 5 of this example is provided with two drums around which the wire rope W is wound, and one winch 5 can feed and wind the two wire ropes W, and each winch. A wire rope W is hung from 5 to each sheave 9. As a result, the dabit 4 suspends the seat member 3 via wire ropes W suspended from four points in the front, rear, left and right sides of the dabit frame 6. In this example, a total of four wire ropes W are extended by the two winches 5, but one winch 5 may be installed for each wire rope W.

Further, in this example, the winch 5 is provided on the dabit 4, but the winch 5 may be provided on the ship side, that is, in the accommodation recess R. In that case, only the sheave 9 is provided on the dabit 4 side, and the wire rope W hung around the sheave 9 is unwound and wound by the winch 5 on the ship side.

Further, as described above, the dabit 4 suspends the seat member 3 via the wire rope W. Although not specifically disclosed, a hook is provided at the tip of the wire rope W, and the hook is hooked on the ring-shaped attachment portions provided at the four corners of the seat member 3 to hook the wire rope W and the seat member. 3 are connected.

Although the mounted boat 2 is omitted in FIG. 3 for easy understanding, the mounted boat 2 is actually held by the seat member 3 here as well.

Returning, as shown in FIGS. 1 and 2, the dabit arms 7 are a set of first dabit arms 7a and 7a connected to the lower part of the right end of each of the short frames 11 and 11 and the first dabit. A pair of second dabit arms 7b, 7b provided on each of the short frames 11 and 11 on the left side of the arm 7a in the drawing is provided in pairs with respect to the dabit frame 6. A pair of first dabit arms 7a and 7a and a set of second dabit arms 7b and 7b are hinged at the upper end to the lower part of each short frame 11 and at the lower end to the floor 10 in parallel. A link is formed to support the dabit frame 6 so as to be swingable in a state of being always horizontal to the ship.

Further, the hydraulic cylinder 8 is hinged between the floor 10 of the accommodating recess R and the first dabit arm 7a, and expands and contracts to drive the dabit arm 7 and swing the dabit frame 6. ing. Specifically, when the hydraulic cylinder 8 is in the most contracted state, as shown in FIG. 1, the dabit arm 7 is in a state of being pulled into the accommodating recess R, and is suspended from the dabit frame 6 via a wire rope W. It is assumed that the seat member 3 is pulled into the accommodating recess R. On the contrary, when the hydraulic cylinder 8 is in the fully extended state, the dabit arm 7 rotates counterclockwise from the state shown in FIG. 1 and swings the seat member 3 parallel to the outside of the accommodating recess R as shown in FIG. It has become like. In this example, the hydraulic cylinder 8 is used as a drive source when driving the dabit 4, but a linear actuator using an electric or other fluid may be used.

Therefore, when the mounted boat 2 is thrown into the sea from the accommodating recess R, the seat member 3 is first mounted on the seat member 3 suspended by the dabit 4 via the wire rope W. After swinging out of the accommodation recess R by the dabit 4, the four wire ropes W are synchronously drawn out by the winch 5 to land the onboard boat 2. Then, even after the on-board boat 2 has landed on the water, when the wire rope W is extended, the on-board boat 2 floats on the sea surface and the seat member 3 sinks into the sea, so that the seat member 3 and the on-board boat 2 can be separated. As a result, the onboard boat 2 can be thrown into the sea from the accommodation recess R.

On the contrary, when the mounted boat 2 on the sea surface is accommodated in the accommodating recess R, the seat member 3 is first swung out of the accommodating recess R and the wire rope W is extended until the seat member 3 is submerged in the sea. Then, the mounted boat 2 is made to enter between the wire ropes W, the mounted boat 2 is moved onto the seat member 3 submerged in the sea, and then the four wire ropes W are synchronously wound up by the winch 5. , While draining the water, lift the mounted boat 2 by scooping it up with the seat member 3. Here, since the seat member 3 of this example is provided with the cushion portion 35, the impact when lifting the mounted boat 2 is absorbed. Then, the seat member 3 is pulled into the accommodating recess R by the dabit 4 and placed on the traveling carriage 21 for accommodating. After that, if the wire rope W is removed from the seat member 3, the mounted boat 2 supported by the seat member 3 by the traveling carriage 21 can be moved along the traveling rail 20.

The dabit 4 is not particularly limited to the configuration of this example as long as the seat member 3 moves in and out of the accommodating recess R in parallel. Although not shown, for example, the dabit 4 is a boom that can be expanded and contracted by a motor, and the seat member 3 is suspended from the tip of the boom at four points in the front, rear, left, and right via a wire rope, and the boom is expanded and contracted to expand and contract the seat member 3. May be allowed to go in and out of the accommodation recess R.

Further, as described above, in the collection device 1 of this example, the wire rope W suspends the seat member 3 at four points in the front, rear, left and right. According to this configuration, the seat member 3 is less likely to be shaken during the loading and unloading work of the mounted boat 2 as compared with the case where the wire ropes are suspended at two points in the front and rear as in the conventional case. Therefore, even if the seat member 3 is blown by the wind or the ship is shaken by the waves when the onboard boat 2 is loaded or unloaded, the onboard boat mounted on the seat member 3 or the seat member 3 The possibility of 2 coming into contact with the ship is greatly reduced.

Further, since the seat member 3 of this example is suspended by the wire rope W at four points in the front, rear, left and right, the side of the mounted boat 2 mounted on the seat member 3 is guided by the wire rope W. Therefore, it is not necessary to provide the seat member 3 with a guide portion for guiding the side of the mounted boat 2.

Further, in the lifting device 1 of this example, the mounted boat 2 is held by the seat member 3 supported at four points by the wire rope W, and the wire rope W is unwound and wound by the winch 5. The onboard boat 2 is put in and collected. Therefore, according to the unloading device 1 of this example, it is not necessary for a person to get on the mounted boat 2 to perform the work at the time of loading and unloading the mounted boat 2, so that the mounted boat 2 is an unmanned aerial vehicle that can be remotely controlled. However, the onboard boat 2 can be loaded and unloaded.

Further, the sheet member 3 of this example is formed in a frame shape. Therefore, even if it is submerged in the sea, the pressure receiving area is small and it is not easily affected by waves. Therefore, the seat member 3 of this example is difficult to move even in the sea, and the mounted boat 2 can easily enter the seat member 3.

Further, as described above, in the dabit 4 of this example, the dabit arm 7 supports the dabit frame 6 that suspends the seat member 3 via the wire rope W so as to be swingable in a state of being always horizontal to the ship. doing. Therefore, according to the lifting device 1 of this example, the mounted boat 2 can always be raised and lowered in a horizontal state. As a result, the hull of the onboard boat 2 is stabilized when the onboard boat 2 is put in or taken out.

Further, as shown in FIG. 4, the wire rope W may be connected to the seat member 3 via the cushioning member 40. According to this configuration, the impact at the time of draining when the onboard boat 2 is lifted can be mitigated, so that the onboard boat 2 can be protected. Here, the cushioning member 40 may be any as long as it can absorb the impact generated between the winch 5 and the seat member 3 at the time of draining, and in FIG. 4, a telescopic member exhibiting a damping force that hinders its own expansion and contraction during expansion and contraction. Although it is a type hydraulic damper, it may be an elastic member such as rubber or a spring.

In this example, the cushioning member 40 is provided between the wire rope W and the seat member 3, but the position where the cushioning member 40 is provided is when the lifting device 1 lifts the mounted boat 2, that is, the wire. It suffices as long as the rope W is in the most extended state and is not wound around the winch 5, and is not limited to between the wire rope W and the seat member 3.

Further, in the unloading device 1 of this example, when the mounted boat 2 is accommodated in the accommodating recess R, the seat member 3 is placed on the traveling carriage 21 provided in the accommodating recess R.

In the past, when replacing a mounted boat, a crane was placed in the containment recess and the mounted boat was hung by the crane, but the inside of the ship shook, making the replacement work difficult. On the other hand, according to this configuration, when the mounted boat 2 of this example is to be replaced with another mounted boat, the mounted boat 2 is placed on the traveling carriage 21 by removing the wire rope W from the seat member 3. Since it can be moved in a state, it can be easily transported to the hangar where another onboard boat is stored. Therefore, according to the above configuration, the onboard boat 2 can be easily replaced.

Further, as shown in FIGS. 1 and 2, the tip end side of the wire rope W of this example is protected by a rubber protective cover 30, and when the mounted boat 2 is brought into between the wire ropes W, it is erroneously contacted. Even if it is allowed to do so, the wire rope W does not damage the mounted boat 2. In this example, the protective cover 30 is made of rubber, but the material is not particularly limited as long as it does not damage the mounted boat 2 even if it comes into contact with the mounted boat 2.

Alternatively, the above-mentioned cushioning member 40 may be made of rubber so that the cushioning member 40 also functions as a protective cover 30 for preventing damage to the side of the mounted boat 2. In this way, the configuration of the protective cover 30 can be omitted.

Subsequently, the mounted boat 2 of this example is provided with a positioning device F capable of positioning the mounted boat 2 with respect to the seat member 3 when the mounted boat 2 is moved onto the seat member 3 submerged in the sea. Has been done.

As shown in FIG. 5, the positioning device F of this example is provided before and after the upper edge on the left and right sides of the mounted boat 2, and is a rotary arm that can rotate back and forth with respect to the traveling direction of the mounted boat 2. It includes 13, 14 and a link rod 15 that connects the front arm 13 and the front arm 14. Here, the front-rear positions of the front arm 13 and the front arm 14 correspond to the positions of the front-rear (left-right in FIG. 6) of the wire rope W that suspends the seat member 3 at four points, front-rear, left-right. ing.

Further, as shown in FIG. 6, the rotary arm 13 (14) of this example is first attached to the base portion 13a (14a) and the base portion 13a (14a) fixed to the upper edge on the side of the mounting boat 2, respectively. An arm portion 13b (14b) rotatably connected to the mounting boat 2 in the traveling direction via a pin 13d (14d) is provided, and each arm portion 13b (14b) has a recessed groove 13c (14c). ) Is provided. Here, the front arm portion 13b and the rear arm portion 14b are attached so that the concave grooves 13c and 14c, respectively, face each other.

The link rod 15 connects the base end portions of the front arm portion 13b and the rear arm portion 14b to each other. At this time, the base end portion of the front arm portion 13b and the base end portion of the rear arm portion 13b with respect to the left and right ends of the link rod 15 with respect to the traveling direction of the mounted boat 2 via the second pins 13e and 14e, respectively. It is rotatably connected back and forth.

That is, the front arm portion 13b and the rear arm portion 14b are connected via pins at two locations, the base portions 13a and 14a and the end portions of the link rod 15.

According to this configuration, when the tip end side of the rear arm portion 14b rotates in the rear direction (left direction in FIG. 6) about the first pin 14d, the base end portion of the rear arm portion 14b is in the front direction (FIG. 6). Rotate in the middle right direction). Here, since the base end portion of the rear arm portion 14b is pin-coupled to the end portion of the link rod 15 as described above, the rotational motion of the rear arm portion 14b is converted into a linear motion of the link rod 15. Will be done. Then, when the link rod 15 linearly moves in the forward direction, the link rod 15 pushes the base end portion of the front arm portion 13b. Then, the linear motion of the link rod 15 is converted into the rotational motion of the front arm portion 13b by the first pin 13d and the second pin 13e, and the tip side of the front arm portion 13b is in the rear direction (left direction in FIG. 6). ).

On the contrary, when the tip side of the front arm portion 13b rotates in the front direction (right direction in FIG. 6), the movement is exactly opposite to that described above, and the tip of the rear arm portion 14b moves in the front direction (FIG. 6). Rotate in the middle right direction).

Therefore, the front arm 13 and the front arm 14 of this example form a link mechanism that rotates in conjunction with each other via the link rod 15.

Next, the operation of the positioning device F of this example described above will be described in detail. First, as shown in FIG. 5A, the mounted boat 2 provided with the positioning device F is brought into the wire rope W for suspending the seat member 3 submerged in the sea at four points in the front, rear, left and right.

Here, the front arm 13 provided on the front side, which is the bow side of the mounted boat 2, is as shown in FIGS. 5 (A) and 6 when the mounted boat 2 is not positioned with respect to the seat member 3. The tip of the front arm portion 13b faces the bow side so that it does not protrude from the side of the onboard boat 2. Therefore, when the mounted boat 2 is brought between the wire ropes W, the front arm portion 13b does not interfere with the wire ropes W.

Then, when the mounted boat 2 advances to a predetermined position and enters, the wire rope W on the rear side (left side in the drawing) with respect to the traveling direction of the mounted boat 2 is provided so as to protrude from the side of the mounted boat 2. It is caught in the concave groove 14c of the rear arm portion 14b. Then, as shown in FIGS. 5 (B) and 7, the tip end side of the rear arm portion 14b is pushed by the wire rope W on the rear side and rotates in the rear direction about the first pin 14d, so that the rear side The base end portion of the front arm portion 13b is pushed by the link rod 15 connected to the base end portion of the arm portion 14b, and the front arm portion 13b rotates in the rear direction about the first pin 13d, and the mounted boat The concave groove 13c of the front arm portion 13b is hooked on the wire rope W on the front side (right side in the drawing) with respect to the traveling direction of 2.

As a result, as shown in FIGS. 5B and 7, the front arm 14 catches the wire rope W on the rear side (left side in the figure), and then the wire rope W on the front side (right side in the figure) catches the wire rope W on the front side (right side in the figure). Since the wire ropes W are held and locked by the front and rear rotary arms 13 and 14, the mounted boat 2 is positioned at an appropriate position.

Further, when the locking of the positioning device F is released and the mounted boat 2 is started from the seat member 3, the mounted boat 2 may be moved backward. When the mounted boat 2 is moved backward, the rear wire rope W is disengaged from the front arm 14, and the front arm portion 13b is pushed open by the front wire rope W, so that the positioning device F is unlocked.

In this example, the front arm 13 and the front arm 14 are connected by a link rod 15 so that the front arm 13 and the front arm 14 are rotationally driven in conjunction with each other. May be driven by an electric motor or the like.

However, the structure of the positioning device F is as described above as long as the mounted boat 2 can be positioned with respect to the seat member 3 by holding the wire rope W when the mounted boat 2 enters between the wire ropes W. Not limited to.

As described above, the mounted boat 2 of this example is provided with a positioning device F that holds the wire rope W and positions the mounted boat 2 with respect to the seat member 3. Therefore, when the mounted boat 2 is lifted, the mounted boat 2 can be positioned at an appropriate position with respect to the seat member 3. Therefore, it is not necessary to steer the mounted boat 2 to an appropriate position with respect to the seat member 3 while swaying in the waves, and the efficiency of the unloading work is improved.

Further, according to the positioning device F of this example, the mounted boat 2 can be positioned only by entering it between the wire ropes W, and it is not necessary for a person to get on the mounted boat 2 to perform the work, so that the mounted boat 2 can be remotely controlled. Even if it is a possible unmanned aerial vehicle, the collection work can be done efficiently.

In addition, in the above-described unloading device 1 of this example, since the mounting boat 2 and the seat member 3 are locked by the positioning device F, the mounting boat 2 is restrained by the seat member 3 and the mounting boat 2 is lifted. The on-board boat 2 is prevented from falling during the collection or loading operation.

Although the preferred embodiments of the present invention have been described in detail above, it is natural that modifications, modifications and changes can be made without departing from the scope of claims.
