Description

Technical Field

[0001] This invention belongs to the field of marine technology, specifically relating to a roller-driven multi-boat storage, deployment and recovery device. Background Technology

[0002] With the development of science and technology and the exploitation of marine resources, the global demand for mother ships carrying multiple smaller boats to safely launch and retrieve these boats in complex sea conditions is increasing. However, traditional boat launch and retrieval methods are limited by technological constraints and cannot meet these requirements. Current stern slipway launch and retrieval systems sometimes require manual hooking, which is difficult to operate, while automatic hooking systems exert significant impact on the smaller boats. Currently, a single slipway on a mother ship can only launch or retrieve one smaller boat, making it impossible to deploy and recover multiple boats simultaneously. Summary of the Invention

[0003] In view of this, the present invention provides a roller-driven multi-boat storage, deployment and retrieval device, which can solve the problem that the current tail slide deployment and retrieval device has difficulty capturing hooks and cannot automatically complete the deployment and retrieval of multiple boats, and realize the deployment and retrieval of several unmanned boats.

[0004] This invention is achieved through the following technical solution:

[0005] A roller-driven multi-boat storage, deployment, and recovery device includes: a deployment chute, a luffing guide rail, a drive assembly, a storage chute, and drive rollers;

[0006] The tail of the luffing guide rail is hinged to the stern deck of the mother ship; the head of the luffing guide rail is mounted on the stern deck of the mother ship via a hydraulic cylinder; the deployment slide is supported on the luffing guide rail, and the drive assembly is installed between the deployment slide and the luffing guide rail, and the drive assembly is used to drive the deployment slide to make linear motion relative to the luffing guide rail.

[0007] One or more storage slipways are fixed side by side on the stern deck of the mother ship, and the storage slipways and deployment slipways are located on the same plane of the same slipway on the mother ship; the deployment slipway is located at the very end of all storage slipways.

[0008] The upper surfaces of the deployment slide and all storage slides are equipped with several drive rollers, which are used to propel the small boat on the deployment slide or storage slide through friction.

[0009] The deployment slide, luffing guide rail, drive assembly, and drive roller constitute the deployment and recovery module; the storage slide and drive roller constitute the storage module; the deployment and recovery module and the storage module located on the same slide of the mother boat share one deployment and recovery module when deploying and recovering multiple small boats, and the storage module is used in sequence.

[0010] Furthermore, the tail end of the luffing guide rail is mounted on the stern deck of the mother ship via a hinged seat, and the length direction of the luffing guide rail is set along the bow-stern direction of the mother ship.

[0011] Two hydraulic cylinders are symmetrically installed on both sides of the luffing guide rail and driven synchronously; one end of each hydraulic cylinder is hinged to the stern deck of the mother ship, and the other end is hinged to the lower surface of the luffing guide rail; when the hydraulic cylinder performs telescopic movement, it drives the luffing guide rail to rotate around the hinge seat.

[0012] Furthermore, a side guide rail is provided on each side of the upper surface of the amplitude guide rail, and both side guide rails are arranged along the length direction of the amplitude guide rail.

[0013] The lower surface of the deployment slide is provided with two or more traveling rollers on each side; the forward direction of the traveling rollers is set along the length of the deployment slide; the deployment slide is supported on the luffing guide rail by the traveling rollers, and the traveling rollers of the deployment slide are installed in the side guide rails on the luffing guide rail, and the two are in rolling cooperation.

[0014] Furthermore, the drive assembly includes a rack, a gear shaft, a hydraulic motor, and gears;

[0015] Two racks are mounted on the upper surface of the luffing guide rail, and each rack is set along the length of the luffing guide rail;

[0016] The hydraulic motor is installed on the lower surface of the deployment slide. The hydraulic motor has two output ends, each of which is connected to a gear shaft via a flange. The gear shaft is coaxially connected to a gear via a flat key. The two gears are symmetrical about the center of the deployment slide. The two gears mesh with two racks on the upper surface of the luffing guide rail, respectively. The hydraulic motor drives the deployment slide to move linearly relative to the luffing guide rail through the transmission of the gears and racks. When the hydraulic cylinder extends to its limit position, the deployment slide moves to its limit position towards the stern of the mother boat, and then the stern of the deployment slide is submerged in the water.

[0017] Furthermore, a guide frame is fixed at the tail of the deployment slide. The guide frame is symmetrically arranged along the direction of the deployment slide and forms a certain guiding angle with the direction of the small boat's entry and exit at the end of the guide frame. Several parallel anti-collision wheels are installed on the inner sides of the two opposite sides of the guide frame along the length of the deployment slide. The anti-collision wheels on each side are arranged along the length of the deployment slide, and the axis of each anti-collision wheel is arranged in the vertical direction.

[0018] Furthermore, the outer surface of the anti-collision wheels is covered with a rubber layer.

[0019] Furthermore, the upper surfaces of the deployment slide and the storage slide are both V-shaped concave surfaces, and several drive rollers are arranged in two rows symmetrically along the length of the deployment slide and the storage slide; and the axial direction of each drive roller is perpendicular to the length of the deployment slide / storage slide, and the axis of each drive roller forms a certain angle with the horizontal plane, which is an acute angle.

[0020] Furthermore, the upper surfaces of the laying slide and the storage slide are provided with several bearing seats, and each drive roller is mounted on the laying slide and the storage slide through the bearing seat; each drive roller includes: a drive motor, a mounting shaft, a roller and a roller bracket;

[0021] The roller bracket has an I-shaped structure, with a mounting shaft fixed to the vertical part of the I-shaped structure; each of the four ends of the horizontal part of the I-shaped structure is equipped with a roller, and the rollers are pin-connected to the roller bracket, with the axial direction of each of the four rollers perpendicular to the axial direction of the mounting shaft; two drive motors are mounted on the roller bracket, each drive motor has two motor shafts, and each motor shaft is connected to a corresponding roller via a flat key; the drive motors are used to drive the rollers to rotate.

[0022] The mounting shaft of the drive roller is mounted on a bearing seat on the laying / storage slide via bearings, and the axial direction of the mounting shaft is consistent with the length direction of the laying / storage slide; and none of the rollers are in contact with the upper surface of the laying and storage slides; the four rollers on each drive roller can swing around the axis of the mounting shaft under the action of the bearings and bearing seats.

[0023] Furthermore, each roller is covered with a textured rubber layer.

[0024] Beneficial effects:

[0025] (1) The mothership of this invention uses a shared deployment and retrieval module on the same slide, and the storage module is used sequentially to deploy and retrieve multiple unmanned boats. The hydraulic cylinder in the deployment and retrieval module can rotate the tail slide at a certain angle, and the drive roller in the deployment slide can rotate to pull the boat up. When the hydraulic cylinder returns the tail slide to a horizontal position, the drive rollers in the deployment and storage slides can rotate to transfer the boat to the deployment and storage positions. Therefore, this invention can realize the automatic deployment and retrieval of multiple boats on the same slide of the mothership, which is safe, reliable and highly applicable. Specifically, this invention enables automatic launching and retrieving of small boats via bottom roller drive, eliminating the need for manual hooking and avoiding the adverse effects of large impact forces found in existing automatic hooking devices. The launching chute can be flipped and leveled back by the extension and retraction control of a hydraulic cylinder, allowing it to be used for launching and retrieving small boats when the mother boat is at a low waterline. It also makes reasonable use of the space on the stern deck of the mother boat, allowing small boats to be transferred between the launching and storage chute, moving small boats from the recovery position to the storage position or vice versa, thus realizing the storage and launching of multiple small boats on a single chute of the mother boat.

[0026] (2) The lower surface of the deployment slide of the present invention is provided with two or more traveling rollers on each side. The traveling rollers are installed in the side guide rails on the luffing guide rail and the two are rolled together. The vertical and horizontal directions of the traveling rollers are restricted by the side guide rails, so that the traveling rollers can only roll along the bow and stern direction of the mother ship, thereby realizing the movement limit of the deployment slide and restricting the displacement of the deployment slide in the width direction of the luffing guide rail.

[0027] (3) The drive component of the present invention includes a rack, a gear shaft, a hydraulic motor and a gear. By driving the hydraulic motor to drive the gear to rotate, the meshing of the gear and the rack is converted into the extension of the deployment slide along the variable amplitude track relative to the tail plate of the mother ship. The motion drive of the deployment slide is realized through gear transmission. The structure is simple, reliable and easy to implement.

[0028] (4) The tail of the deployment slide of the present invention is fixed with a guide frame, which is symmetrically arranged along the direction of the deployment slide and forms a certain guiding angle with the direction of the boat's entry and exit at the end of the guide frame; a row of anti-collision wheels are arranged on the guide frame in the vertical direction to assist the unmanned boat aligned with the slide to rush into the deployment slide, and the boat is recovered to the deployment and recovery module. After the deployment slide and the storage slide are restored to the same level, the boat is pulled to the storage module by driving the roller to rotate clockwise, thus freeing up the recovery module for the recovery of the next boat.

[0029] (5) The deployment slide and storage slide of the present invention are equipped with rows of symmetrically distributed drive rollers at a certain angle to the horizontal direction. The drive rollers rotate clockwise or counterclockwise and can play a traction role during the deployment and retrieval of the small boat, driving the small boat to go up or down. In the above-mentioned drive roller structure, the mounting shaft is installed in the slide and can only rotate around its axis. The roller bracket is fixedly connected to the mounting shaft, and the drive motor is fixedly connected to the roller bracket. The roller is installed on the roller bracket and controlled by the drive motor. The drive roller can swing around its mounting shaft on the deployment slide and can adapt to the changes in the bottom profile of the small boat.

[0030] In summary, the deployment and retrieval module of this invention is a device that controls the extension and retraction of a hydraulic cylinder to drive a slide device connected to the mother ship's deck via a hinged seat to rotate upwards around the hinged seat, causing the small boat and the slide to tilt together at a certain angle. Then, between the deployment slide and the luffing guide rail, the meshing between the gear structure connected to the deployment slide and the rack fixed to the luffing guide rail converts the rotation of the gear structure into relative movement between the deployment slide and the luffing guide rail. The traveling rollers installed below the deployment slide and in contact with the luffing guide rail roll relative to each other. The deployment slide carries the small boat out of the mother ship's stern deck into the seawater. Subsequently, the drive rollers arranged below the small boat in the deployment slide rotate counterclockwise, and the friction generated by the relative movement between the small boat and the drive rollers pulls the small boat into the water. The small boat is then deployed into the water and sails away from the mother ship. After the boat is deployed, the reverse operation described above is performed, causing the deployment and recovery module to reset. After the deployment module is reset, unmanned boats placed on the nearest storage module on the same slide can continue to be deployed. The storage module consists of a storage slide and drive rollers built into it and located below the boat. The storage slide and the horizontal deployment slide are located on the same plane and on the same straight line. The drive rollers fixed to the storage slide and the deployment slide have the same installation method and tilt angle, and the drive rollers rotate at the same speed, transferring the boat placed on the storage slide to the deployment slide and the storage slide. After the boat reaches the deployment and recovery module, deployment can continue. According to the number of boats to be deployed, multiple sets of storage slides can be arranged after the storage slide to complete the storage, deployment and recovery of multiple boats.

Detailed Implementation

[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Example 1:

[0039] This embodiment provides a roller-driven multi-boat storage, deployment, and recovery device. See attached drawing. Figures 1-3 It includes: guide frame 1, anti-collision wheel 2, hinge seat 3, hydraulic cylinder 4, deployment slide 5, luffing guide rail 6, storage slide 7, rack 8, gear shaft 9, drive roller 10, hydraulic motor 11, gear 12, and traveling roller 13.

[0040] The tail of the luffing guide rail 6 is mounted on the stern deck of the mother ship via a hinge seat 3, and the length of the luffing guide rail 6 is arranged along the bow-stern direction of the mother ship. The head of the luffing guide rail 6 is mounted on the stern deck of the mother ship via a hydraulic cylinder 4, that is, one end of the hydraulic cylinder 4 is hinged to the stern deck of the mother ship, and the other end is hinged to the lower surface of the luffing guide rail 6. When the hydraulic cylinder 4 performs telescopic movement, it drives the luffing guide rail 6 to rotate upward around the hinge seat 3 at a certain angle, or to return to a horizontal state. In this embodiment, two hydraulic cylinders 4 are used, and the two hydraulic cylinders 4 are symmetrically installed on both sides of the luffing guide rail 6 and driven synchronously.

[0041] The upper surface of the luffing guide rail 6 is provided with a side guide rail on each side, and the two side guide rails are arranged along the length direction of the luffing guide rail 6; the luffing guide rail 6 is also provided with two racks 8, the two racks 8 are arranged along the length direction of the luffing guide rail 6, and the two racks 8 are located between the two side guide rails; each rack 8 is fixed to the luffing guide rail 6 by welding.

[0042] The lower surface of the deployment slide 5 is provided with two or more traveling rollers 5 on each side; the forward direction of the traveling rollers 5 is set along the length of the deployment slide 5; the deployment slide 5 is supported on the luffing guide rail 6 by the traveling rollers 5, and the deployment slide 5 and the luffing guide rail 6 can move in a relative straight line, that is, the traveling rollers 5 of the deployment slide 5 are installed in the side guide rails on the luffing guide rail 6, and the two roll in cooperation. The vertical and horizontal directions of the traveling rollers 5 are restricted by the side guide rails, so that the traveling rollers 5 can only roll in the bow and stern direction of the mother ship; wherein, the central axis of the traveling rollers 5 is fixed to the lower surface of the deployment slide 5 by welding.

[0043] The lower surface of the deployment slide 5 is also equipped with a hydraulic motor 11, which is bolted to the lower surface of the deployment slide 5. The hydraulic motor 11 has two output ends, each of which is connected to a gear shaft 9 through a flange. The gear shaft 9 is coaxially connected to a gear 12 through a flat key. The two gears 12 are symmetrical about the center of the deployment slide. The two gears 12 mesh with two racks 8 on the upper surface of the luffing guide rail 6 respectively. The hydraulic motor 11 drives the deployment slide 5 to make linear motion relative to the luffing guide rail 6 through the transmission of the gears 12 and racks 8. That is, by controlling the hydraulic motor 11 to drive the gears 12 to rotate, the meshing of the gears 12 and racks 8 is converted into the deployment slide 5 extending outward relative to the stern plate of the mother boat along the luffing guide rail 6. When the hydraulic cylinder 4 extends to the limit position, the deployment slide 5 moves to the stern of the mother boat to the limit position, and the stern of the deployment slide 5 is submerged in the water.

[0044] The guide frame 1 is welded and fixed to the tail of the deployment slide 5. The guide frame 1 is symmetrically arranged along the direction of the deployment slide, and the end of the guide frame 1 forms a certain guiding angle with the direction of the boat's entry and exit. Several parallel anti-collision wheels 2 are installed on the inner sides of the two opposite sides of the guide frame 1 along the length of the deployment slide 5. Several anti-collision wheels 2 on each side are arranged along the length of the deployment slide 5, and the axis of each anti-collision wheel 2 is arranged in the vertical direction. Each anti-collision wheel 2 is rotatably mounted on a central shaft, which is fixed to the guide frame 1 by welding. The outer surface of the anti-collision wheel 2 is covered with a rubber layer.

[0045] The storage slide 7 is fixed to the stern deck of the mother ship by welding, and the storage slide 7 is connected end to end to the luffing guide rail 6 with the same length direction. That is, the storage slide 7 and the deployment slide 5 are located on the same plane of the same slide of the mother ship. The storage slide 7 is closer to the bow of the mother ship than the luffing guide rail 6. And when the luffing guide rail 6 is in a horizontal state, that is, when the angle between the luffing guide rail 6 and the horizontal plane is 0°, the deployment slide 5 located on the luffing guide rail 6 is flush with the storage slide 7.

[0046] The upper surfaces of both the deployment slide 5 and the storage slide 7 have V-shaped cross-sections, with an obtuse angle between the V-shapes. Specifically, the upper surfaces of both slides are concave V-shaped surfaces. Several drive rollers 10 are installed on both sides of each concave V-shaped surface, arranged in rows and symmetrically distributed at an angle to the horizontal. These drive rollers 10 are arranged symmetrically in two rows along the length of both slides. The axial direction of each drive roller 10 is perpendicular to the length of the slide / storage slide 7, and the axis of each drive roller 10 forms an acute angle with the horizontal plane. The drive rollers 10 are used to propel the small boat along the deployment slide 5 or storage slide 7 using friction. Rotating clockwise or counterclockwise, the drive rollers 10 can provide traction during the deployment and retraction of the small boat, propelling it upwards or downwards.

[0047] Specifically, the upper surfaces of both the placement slide 5 and the storage slide 7 are provided with several bearing seats, and each drive roller 10 is mounted on the placement slide 5 and the storage slide 7 through these bearing seats; see attached diagram. Figure 4 Each drive roller 10 includes: a drive motor 101, a mounting shaft 102, a roller 103, and a roller bracket 104;

[0048] The roller bracket 104 has an I-shaped structure. A mounting shaft 102 is welded to the vertical portion of the I-shaped structure. A roller 103 is mounted at each of the four ends of the horizontal portion of the I-shaped structure, and the rollers 103 are pin-connected to the roller bracket 104. The axial directions of all four rollers 103 are perpendicular to the axial direction of the mounting shaft 102. Two drive motors 101 are bolted to the roller bracket 104. Each drive motor 101 has two motor shafts, and each motor shaft is connected to a corresponding roller 103 via a flat key. The drive motors 101 drive the rollers 103 to rotate. Each roller 103 is covered with a textured rubber layer.

[0049] The mounting shaft 102 of the drive roller 10 is mounted on a bearing seat on the deployment slide 5 / storage slide 7 via bearings, and the axial direction of the mounting shaft 102 is consistent with the length direction of the deployment slide 5 / storage slide 7; and all rollers 103 do not contact the upper surface of the deployment slide 5 and the storage slide 7; the four rollers 103 on each drive roller 10 can swing left and right around the axis of the mounting shaft 102 under the action of the bearings and bearing seats to adapt to the changes in the bottom profile of different types of small boats;

[0050] The guide frame 1, anti-collision wheel 2, hinge seat 3, hydraulic cylinder 4, deployment slide 5, luffing guide rail 6, rack 8, gear shaft 9, drive roller 10, hydraulic motor 11, gear 12 and traveling roller 13 constitute the deployment and recovery module; the storage slide 7 and drive roller 10 constitute the storage module.

[0051] In this embodiment, there are two small boats on the stern deck of the mother boat that need to be deployed and retrieved. The two small boats are referred to as unmanned boat one and unmanned boat two, respectively.

Unmanned surface vessel (USV1) and USV2 are positioned side-by-side on the stern deck of the mother vessel, with USV1 on the deployment slide 5 and USV2 on the storage slide 7. For deployment operations, please refer to the appendix. Figure 5 First, deploy unmanned surface vessel one, then deploy unmanned surface vessel two;

[0057] Steps 1-4 are performed in reverse order to restore the device to its initial state.

[0058] Steps 1-5: Control the drive rollers 10 on the storage slide 7 and the deployment slide 5 to rotate counterclockwise simultaneously. Under the action of the friction of the drive rollers 10, the second unmanned surface vessel will move to the position of the first unmanned surface vessel.

During the recovery operation, unmanned surface vessel 2 is recovered first, and then unmanned surface vessel 1 is recovered.

[0064] Steps 2-3: Control the unmanned surface vessel 2 to align with the deployment slide 5. With the assistance of the guide frame 1 and the anti-collision roller 2, control the unmanned surface vessel 2 to accelerate and guide it upwards to enter the tail of the deployment slide 5.

[0065] Steps 2-4: Control the drive roller 10 on the deployment slide 5 to rotate clockwise. The unmanned surface vessel 2 moves upward under the friction of the roller and completely enters the deployment slide 5.

[0066] Steps 2-5: Control the hydraulic cylinder 4 to retract until the luffing guide rail 6 is in a horizontal state, that is, the unmanned surface vessel returns to the horizontal position.

[0067] Steps 2-6: Control the drive rollers 10 on the storage slide 7 and the deployment slide 5 to rotate clockwise simultaneously, so that the unmanned surface vessel 2 moves towards the bow of the mother vessel and returns to its initial position, that is, the unmanned surface vessel 2 is located on the storage slide 7, thus completing the recovery of the unmanned surface vessel 2.

[0068] Steps 2-7 are repeated from steps 2-1 to 2-5 until the unmanned surface vessel returns to a horizontal position and is positioned on the deployment rail 5, thus completing the recovery of the unmanned surface vessel.
