Description

[Technical Field]

[0001] The present invention relates to a launching and retrieval device and a launching and retrieval system. [Background technology]

[0002] For example, in surface security and rescue operations, marine surveys, and the like, a launch vehicle, such as a small boat or underwater vehicle housed in a dock on a mother ship, may be launched onto or into the water. The launched vehicle supports lifesaving operations, observation operations, and the like. In this case, the mother ship is equipped with a launch and retrieval device that launches and retrieves the launched vehicle.

[0003] Generally, in the launching and retrieval device installed on the mother ship, the stern door (transom hatch) is opened by tipping it into the water, and the stern hatch lowered into the water is used as an aisle to transport the object to be launched toward the stern (hereinafter referred to as launching) and store it in the dock (hereinafter referred to as retrieval).

[0004] In this case, methods and devices have been proposed for providing a transport means such as a belt conveyor or rollers in the dock and driving the transport means to dump and retrieve the object to be dumped (see, for example, Patent Document 1). In this case, the transport means applies a force to the object to be dumped that moves it in the opposite direction to the direction of travel of the mother ship, and applies a force to the object to move it in the same direction as the direction of travel of the mother ship to retrieve it. Another method involves providing a net with ropes stretched on both sides and using a winch (winding machine) to reel in the ropes from both sides of the net, thereby applying a surface force to the object to be dumped with the net to move it, pushing the object out from the stern and dumping it over the mother ship.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-038706 Summary of the Invention [Problem to be solved by the invention]

[0006] However, when using a transport means to launch an object, a large device must be installed. Furthermore, the device is complex, requiring a large number of components, making maintenance difficult. When using a net to launch an object, the ropes on both sides of the net are connected via the net. Once the launch is complete, the ropes are pulled from both sides, applying sudden tension. Therefore, it is necessary to stop the winch before the ropes are stretched to prevent damage to the winch and rope. Furthermore, if a backing rope is installed, the net installed in the center forward and the backing rope will cross, potentially causing friction and reducing durability. Furthermore, if a backing rope is not installed, the object will move autonomously once it separates from the net. Therefore, for example, if the waves are rough and the water surface is unstable, the object will be launched out of the dock in an unstable state.

[0007] In view of the above circumstances, the present invention aims to provide a loading and retrieval device and a loading and retrieval system that are simply configured and capable of stably loading and retrieving objects to be loaded. [Means for solving the problem]

[0008] In order to achieve the above-mentioned objectives, the launching and retrieval device of this invention is a launching and retrieval device that launches or retrieves an object to be launched from a dock installed at the stern of a mother ship outside the dock, and is equipped with multiple launch ropes that are located at multiple points on the dock and each pull the object to be launched, applying force to push it out of the dock from the stern, multiple launch winches that each wind up the multiple launch ropes, and retrieval ropes that are connected to the object to be launched and pull it.

[0009] In addition, the throwing and retrieval system of the present invention comprises the above-mentioned throwing and retrieval device and an object to be thrown in or retrieved by the throwing and retrieval device, and the object to be thrown in is equipped with a throwing device having a protruding member for engaging the throwing rope. [Effects of the Invention]

[0010] According to this invention, multiple launch winches are provided, each winding up a multiple number of launch ropes, and a pushing force is applied to the launch object from the stern in multiple locations. This allows the launch object to be launched and retrieved without relying on large transport means, and the dock can be used more efficiently with a simple configuration. Furthermore, when the launch object is launched, a lifting rope or the like can be connected to the center of the launch object and maintained until the launch is stable.

[0012] The following describes a loading and retrieval device and a loading and retrieval system according to embodiments of the invention, with reference to the drawings. In the following drawings, components with the same reference numerals are identical or equivalent and are common throughout the following embodiments. The dimensional relationships between components in the drawings may differ from those in reality. The configurations of components shown throughout the specification are merely illustrative and are not limited to the configurations described in the specification. Not all of the devices described in the specification may be included. In particular, the combinations of components are not limited to the combinations in each embodiment, and components described in other embodiments may be applied to other embodiments. The positions of devices and equipment are not absolute positions, but are determined relative to other devices. When multiple similar devices are distinguished by subscripts, the reference numerals, subscripts, etc. may be omitted if there is no need to distinguish or identify them.

[0013] Embodiment 1 1 is a diagram showing the configuration of a launching and retrieval device 100 according to the first embodiment. The launching and retrieval device 100 is disposed in a space that serves as a dock 1100 provided at the stern of a mother ship 1000, and is a device that launches a target object 1 onto or into the water outside the dock 1100, or retrieves the target object 1 from the water outside the dock 1100. Here, the bottom surface of the portion of the dock 1100 that houses the target object 1 is an inclined surface that serves as a slope, and when the target object 1 is launched, the launching of the launching and retrieval device 100 can be assisted by applying the force of the target object's own weight.

[0014] Here, the object to be thrown 1 in the first embodiment is a small boat, and the case where the throwing and retrieval device 100 throws the small boat into the water will be described. Furthermore, the direction within the dock 1100 where the throwing and retrieval device 100 is installed will be described as the fore-and-aft direction, with the direction connecting the bow and stern of the mother ship 1000 being the front, and the bow side of the mother ship being the front, and the stern side of the mother ship being the rear. Furthermore, the left-right direction relative to the fore-and-aft direction will be described as the right side when looking from the stern side of the mother ship towards the bow side of the mother ship (which is also the starboard side of the small boat that is the object to be thrown 1) being the right, and the left side (which is also the port side of the small boat that is the object to be thrown 1) being the left.

[0015] As shown in FIG. 1, the loading and unloading device 100 in the first embodiment has a loading section 200, a unloading section 300, and a hatch section 400.

[0016] The launching unit 200 is installed in the dock 1100 and assists in launching the target object 1 onto the water. The launching unit 200 in the first embodiment has a launching rope 210, a launching winch 220, a launching driver 230, and a pulley 240.

[0017] The throwing ropes 210 (throwing rope 210A and throwing rope 210B) are ropes that, when throwing the object to be thrown into the water, are wound up by the throwing winch 220 to apply a pushing force from the stern of the mother ship 1000 through the hatch section 400. Here, the throwing and retrieval device 100 in the first embodiment has at least two throwing ropes 210, and when throwing, they apply force to the object to be thrown, separately on the left and right. For this reason, even if the lifting rope 310, which will be described later, is connected to the center front part of the object to be thrown 1, the throwing rope 210 and the lifting rope 310 do not interfere with or come into contact with each other. Here, the right side will be described as throwing rope 210A and the left side will be described as throwing rope 210B. One end of the throwing rope 210 is ring-shaped (loop), and as will be described later, the throwing rope 210 is secured to the throwing object 1 by hooking the loop portions from the left and right sides of the throwing object 1 onto the throwing tool 20 provided at the bow of the throwing object 1. Therefore, when the throwing object 1 is reeled in and moves to a set position toward the stern of the mother ship 1000, the throwing rope 210 that was hooked onto the throwing tool 20 comes loose and detaches from the throwing tool 20. Here, the throwing rope 210 is made of a material that floats on water, such as fiber.

[0018] The throwing winches 220 (throwing winch 220A and throwing winch 220B) are devices that are driven when throwing the object to be thrown 1 and that wind up the throwing rope 210. To wind up each throwing rope 210, the throwing winches 220 have two throwing winches 220 on the left and right, corresponding to each throwing rope 210. Here, the right side will be described as throwing winch 220 that winds up throwing rope 210A, and the left side will be described as throwing winch 220B that winds up throwing rope 210B. Each throwing winch 220 winds up an independent throwing rope 210, so there is no pulling on a single rope. Furthermore, the two throwing winches 220 in the first embodiment are installed forward of the dock 1100 (toward the bow of the mother ship 1000). For example, if the stern portion of the mother ship 1000 is open-top (without a roof), there is often not enough space behind the dock 1100 (stern side of the mother ship 1000) to install the throwing winch 220. Even if it were possible to install it behind the dock 1100, it would be prone to getting wet. By installing the throwing winch 220 in the front of the dock 1100, the throwing winch 220 and throwing drive machine 230 can be protected from water by preventing them from getting wet.

[0019] The throwing drive mechanism 230 is driven to rotate based on, for example, the operator's operation, thereby driving the throwing winch 220. The drive mechanism may be, for example, electrically driven, hydraulically driven, or pneumatically driven. Here, a throwing drive mechanism 230 may be provided for each throwing winch 220. However, in this configuration, the rotation shaft 231 of the throwing drive mechanism 230 is connected to two throwing winches 220, allowing the two throwing winches 220 to be driven simultaneously. The two throwing winches 220 can be driven synchronously by sharing the rotation shaft 231 of the throwing drive mechanism 230. Therefore, a force pushing the throwing object 1 from the stern in the left-right direction can be applied to the throwing object 1 in a balanced manner. Furthermore, the throwing drive mechanism 230, which will be described later, can be installed in the front center of the dock 1100 together with the lifting drive mechanism 330, allowing the installation locations of the drive system equipment to be consolidated.

[0020] Disk-shaped pulley (sheave) 240 (pulley 240A and pulley 240B) changes the direction of movement of throwing rope 210 (the direction in which throwing rope 210 pulls object to be thrown 1) that is wound up by throwing winch 220. In throwing and retrieval device 100 in embodiment 1, as shown in FIG. 1 , pulley 240 is installed at a position on the stern side of throwing winch 220 in dock 1100. By using pulley 240 to change the direction of movement of throwing rope 210, throwing rope 210 can apply force to object to be thrown 1 in a direction that pushes object to be thrown 1 from the stern, even when throwing winch 220 is installed in front of dock 1100.

[0021] The hoisting unit 300 is installed in the dock 1100 and assists in hoisting the target object 1 from the water. The hoisting unit 300 has a hoisting rope 310, a hoisting winch 320, and a hoisting drive machine 330.

[0022] The lifting rope 310 is a rope that, when the target object 1 is lifted from the water, applies force to lift the target object 1 from the stern of the mother ship 1000 into the dock 1100 by being reeled in by the lifting winch 320. It also functions as a backing rope that stabilizes the target object 1 as it is launched onto the water by adjusting the speed at which the target object 1 moves toward the stern. The lifting rope 310 has a connecting fitting 311 attached to its tip. The connecting fitting 311 is a fitting that can be connected to and disconnected from the target object-side connecting device 33 of the target object 1 with a single touch. Here, the lifting rope 310 has a larger diameter than the throwing rope 210, e.g., 16 mm compared to 12 mm for the throwing rope 210, in order to lift the target object 1 into the dock 1100.

[0023] The lifting winch 320 is a device that is driven when lifting the object to be thrown 1 and winds up the lifting rope 310. When the lifting winch 320 throws the object to be thrown 1, it adjusts the winding force to pull the lifting rope 310 and adjust the speed of the object to be thrown 1 moving toward the stern. The lifting winch 320 is installed in the front center part of the dock 1100.

[0024] The lifting drive machine 330 is rotationally driven based on, for example, the operation of an operator, to drive the lifting winch 320. For this reason, the lifting drive machine 330 is installed in the front center part of the dock 1100, similar to the lifting winch 320.

[0025] 2 is a diagram showing the configuration of the hatch section 400 according to embodiment 1. The hatch section 400 is mainly installed in the stern of the mother ship 1000, and opens the stern of the mother ship 1000 based on the operation of an operator when the object to be dropped off 1 is dropped off and stored. The hatch section 400 has a stern door 410, a cylinder 420, and a guide 430.

[0026] The guide 430 serves as an introduction path that leads the target object 1 from the water to the dock 1100 and an exit path that leads the target object 1 from the dock 1100 to the water. The cylinder 420 is driven to open and close the stern door 410. For example, the cylinder 420 can be a hydraulic cylinder, an electric cylinder, or a linear actuator equipped with a ball screw and a nut that moves linearly along the ball screw. When the target object 1 is launched or retrieved, the stern door 410 rotates rearward about a hinge portion provided below, opening the stern section of the mother ship 1000. The stern door 410 is usually secured with a lock pin (not shown) and becomes rotatable, for example, when an operator removes the lock pin. After the stern section is opened, the stern door 410, together with the guide 430, serves as an exit path or an introduction path. Here, the stern door 410 in the first embodiment can be rotated to an angle greater than the angle at which it is parallel to the slope of the bottom surface of the dock 1100 (hereinafter referred to as the maximum inclination angle).

[0027] 3 is a diagram illustrating an example of the attachment 10 possessed by the object to be dropped 1 according to the first embodiment. The object to be dropped 1 is also provided with an attachment for connecting the throwing rope 210 and the hoisting rope 310. The attachment 10 is installed on the object to be dropped 1 and is an attachment for connecting the object to be dropped 1 to the throwing rope 210 and the hoisting rope 310. The object to be dropped 1 according to the first embodiment has the attachment 10 comprising the throwing tool 20 and the hoisting tool 30.

[0028] FIG. 4 is a diagram showing an example of the throwing tool 20 according to the first embodiment. The throwing tool 20 has two protrusions 21 installed on the left and right sides of the object to be thrown 1. Here, for example, the protrusions 21 are installed on the left and right front (bow portion) of the object to be thrown 1, respectively. The two protrusions 21 are protruding members onto which the throwing rope 210A and the throwing rope 210B are hooked, respectively. Here, as shown in FIG. 3, the tips of the two protrusions 21 are located aft of the bow of the object to be thrown 1, which is a small boat.

[0029] As shown in FIG. 4, the protrusion 21 has a cylindrical (rod-like) shape without any curves or depressions. Furthermore, as shown in FIG. 4, the tip of the protrusion 21 has a rounded shape, such as a hemispherical shape. Therefore, when the target object 1 is to be thrown, it is possible to prevent the throwing rope 210 from becoming stuck even when the target object 1 is thrown onto the water. Here, the tip of the protrusion 21 may have a chamfered corner. Furthermore, the width between the two protrusions 21 is not particularly limited, and the distance may be adjusted depending on the installation position of the throwing tool 20 on the target object 1, etc.

[0030] The lifting device 30 also has a rope fastener 31, a connecting rope 32, and a target object side connecting device 33. The rope fastener 31 fastens the connecting rope 32. The connecting rope 32 is connected to the target object 1 side and functions as a single rope with the lifting rope 310. The connecting rope 32 is of a length that allows it to be retrieved by crew members on board the small boat that is the target object 1. The target object side connecting device 33 connects to a connecting fitting 311 attached to the tip of the lifting rope 310. The target object side connecting device 33 is, for example, a shackle.

[0031] FIG. 5 is a diagram showing the flow of work when the target object 1 according to the first embodiment is thrown onto the water. FIG. 6 is a diagram illustrating a simplified connection state between the target object 1 and the throwing and hoisting device 100. The work will be described assuming that it is performed by a worker, for example. First, in preparation for throwing, the connector 311 installed at one end of the hoisting rope 310 is connected to the target object-side connecting device 33, and the hoisting rope 310 is connected to the target object 1 (step S1). Next, two throwing ropes 210 are hooked onto the protrusions 21 of the throwing device 20 from the left and right sides, respectively, and moored (step S2). At this time, as shown in FIG. 6(a), the throwing rope 210 is pulled toward the stern and therefore does not come off the throwing device 20.

[0032] Next, the worker performs the stern opening work to deposit the object to be deposited 1. The lock pin of the stern door 410 is released (step S3), and the stern door 410 is rotated to a set angle to open the stern of the mother ship 1000. Here, the stern door 410 is rotated to an angle that makes it parallel to the slope on the bottom of the dock 1100 (step S4).

[0033] Next, the worker performs the throwing operation. In the throwing operation, the worker drives the throwing winch 220 to wind up the throwing rope 210 (step S5). As the throwing rope 210 is wound up, it applies a force to the object to be thrown 1 toward the stern, as shown by the arrow in FIG. 6(a). When the object to be thrown 1 is pushed to a predetermined fixed position (step S6), the stern door 410 is further rotated to the maximum inclination angle (step S7), so that the force of its own weight is further applied to the object to be thrown 1, urging it to move toward the rear (stern). Then, as shown in FIG. 6(b), when the object to be thrown 1 moves and the protrusion 21 reaches a position rearward of the pulley 240 (stern side of the mother ship 1000) in the fore-and-aft direction, the throwing rope 210 slips off the protrusion 21 and becomes detached. Then, the object to be thrown 1 continues to move and is thrown into the water (step S8). At this time, the hoisting rope 310 is connected to the object 1 to be thrown.

[0034] When the target body 1 is launched onto the water, the target body 1, which is a small vessel, starts its main engine (not shown) (step S9). If the main engine cannot be started, a retrieval operation will be carried out. On the other hand, since the target body 1 has its main engine started and is now capable of autonomous movement, the crew of the target body 1, for example, releases the connection between the target body side connecting device 33 and the connecting fitting 311 (step S10). After that, on the mother ship 1000 side, the retrieval rope 310 is retrieved and post-launch operations such as closing the stern door 410 are carried out (step S11).

[0035] 7 is a diagram showing the workflow for recovering the target object 1 from the water according to the first embodiment. First, in preparation for recovery, workers open the stern. The lock pin of the stern door 410 is released (step S21), and the stern door 410 is rotated to open the stern of the mother ship 1000. Here, the stern door 410 is rotated to the maximum tilt angle (step S22).

[0036] Furthermore, the worker throws the lifting rope 310, to which a buoy or the like is connected, onto the water and floats it on the water (step S23). For example, the crew of the target object 1 retrieves the lifting rope 310 and connects the target object side connecting device 33 to the connecting fitting 311 (step S24). Then, the target object 1 is pulled by the lifting rope 310 to prevent the lifting rope 310 from sagging.

[0037] Furthermore, the worker performs the hoisting operation. In the hoisting operation, the worker drives the hoisting winch 320 to reel in the hoisting rope 310 (step S25). As the hoisting rope 310 is reeled in, it applies a force in a direction that pulls the target object 1 into the dock 1100. Once the target object 1 has been reeled in to a predetermined fixed position in the dock 1100 (step S26), the stern door 410 is rotated to an angle that is parallel to the slope on the bottom of the dock 1100 (step S27). Then, once the target object 1 has been further reeled in to the dock 1100 (step S28), the stern door 410 is closed (step S29). Then, post-hoisting work is performed, such as securing the target object 1 and loosening the hoisting rope 310 (step S30).

[0038] As described above, the throwing and retrieving device 100 according to the first embodiment is provided with throwing winches 220 on the left and right sides of the dock 1100, respectively, for winding up the throwing rope 210, and applies force separately to the left and right (at multiple locations). This allows the throwing and retrieving of the object 1 without relying on large conveying means such as a belt conveyor or rollers, and the dock 1100 can be used more efficiently with a simple configuration. Therefore, a larger object 1 can be accommodated compared to the space available in the dock 1100. Furthermore, the stern door 410, the winch's hoisting capacity, and other aspects of the device can be easily modified to match the size (width, overall length, etc.) of the object 1. Furthermore, in the throwing and retrieving device 100 according to the first embodiment, the throwing rope 210 is connected to the object 1 separately on the left and right, leaving the center of the object 1 open. Therefore, the hoisting rope 310 of the hoisting unit 300 can be connected to the object 1 without intertwining with the throwing rope 210. Therefore, by keeping the rope connected until the target object 1 can move stably on the water, the target object 1 can be launched stably. Also, by keeping the hoisting rope 310 connected to the target object 1 when it is launched, the target object 1 can be lifted up in the event of an unforeseen incident.

[0039] Furthermore, according to the throwing and retrieval device 100 of the first embodiment, the throwing ropes 210 each have a loop at the end, and the looped portions are hooked onto the throwing implements 20 on the left and right sides of the object to be thrown 1, and a force is applied to the object to be thrown 1, so that the object to be thrown 1 naturally comes off as the object to be thrown 1 moves. Therefore, there is no need to cut off the throwing ropes 210, and the object to be thrown 1 can be thrown smoothly.

[0040] Furthermore, according to the first embodiment of the launching and hoisting device 100, multiple launching winches 220 share the same rotation shaft of the launching drive machine 230, allowing them to be driven synchronously. This prevents unevenness in the hoisting operation between the launching winches 220. In addition, the installation positions of the hoisting drive machine 330 and the drive system equipment can be centralized.

[0041] Furthermore, according to the launching and retrieval device 100 of the first embodiment, the direction of the force of the launch rope 210 can be changed by the pulley 240. Therefore, the launch winch 220 and the launch drive machine 230 can be installed at the front side of the mother ship 1000, not at the stern, in the dock 1100. By installing the equipment in a position that will not be covered in water, it is possible to protect the drive system equipment in particular.

[0042] According to the throwing device 20 of the first embodiment, the object to be thrown 1 has a cylindrical protrusion 21 onto which the throwing rope 210 is hooked. The protrusion 21 has no recess or the like formed therein and has a rounded tip. Therefore, as the object to be thrown 1 moves aft (towards the stern of the mother ship), the throwing rope 210 can be smoothly released and detached.

[0043] Embodiment 2 Here, the throwing and retrieving device 100 has been described as a device that throws and retrieves the object to be thrown 1, but it may also be a device that only throws the object.

[0044] Furthermore, in the case of the throwing and hoisting device 100 of the first embodiment, it has been described that one throwing rope 210 is connected to each of the left and right sides of the object to be thrown 1. Alternatively, for example, the object to be thrown 1 may have a plurality of protrusions 21 on the left and right sides, and the throwing ropes 210 may be connected to each of them to perform winding.

[0045] Although the description has been given assuming that the target object 1 to be deployed and retrieved by the deployment and retrieval device 100 is a small vessel, the present invention is not limited to this. The target object 1 can also be a marine structure such as a buoy, a survey boat, an unmanned boat, or an unmanned underwater vehicle (UUV), etc.
