AI Technical Summary
The existing lifeboat release hook device cannot transmit the force on the hook to the manual handle when the rescue boat is under the weight of the rescue boat, resulting in the inability to carry-load decoupling.
A lifeboat carrying hook device is designed, including a base plate, lifting plate, hook, stop plate, limit plate, thrust shaft, handle, baffle, release arm, safety pin lock, cable plate, limit rod, pin shaft and hydrostatic pressure releaser. The release arm is driven to rotate through the hydrostatic pressure releaser, and the rotation of the thrust shaft is released. The operating handle causes the thrust shaft to rotate. When the thrust shaft rotates to a certain angle, the stop plate falls into the groove of the thrust shaft, the hook rotates backward, and the wire rope falls off to achieve load-load decoupling.
After the lifeboat is released to the water surface, the driving system is rotated through the hydrostatic pressure releaser to effectively transmit force, remove the wire rope on the hook, and complete the load-load decoupling operation.

[0002] At present, according to the requirements of the classification society, it is necessary to meet multiple intentional continuous operation steps to open the release hook device; the existing release hook device cannot meet the requirement that when the release hook device bears the dead weight of the rescue boat, the force on the hook cannot be transmitted to the manual handle, that is, it cannot achieve unhooking with load. Summary of the Invention
[0003] Aiming at the above disadvantages, the purpose of the utility model is to provide a lifeboat hook device with load that can enable the rescue boat to unhook with load.
[0004] To achieve the above purpose, the technical solution of the utility model is a lifeboat hook device with load, which is characterized in that it includes a bottom plate, a lifting plate, a hook, a stop plate, a limit plate, a thrust shaft, a handle, a baffle plate, a release swing arm, a safety pin lock, a cable stopper plate, a limit rod, a pin shaft and a hydrostatic pressure release device;
[0005] Two lifting plates are arranged in parallel on the bottom plate. The hook is rotatably arranged at the upper end between the two lifting plates through a pin shaft. The rear end of the stop plate is rotatably arranged between the two lifting plates at the lower end of the hook through a pin shaft. A groove for clamping the hook is arranged on the upper end surface of the stop plate. A limit plate is arranged between the two lifting plates below the rear of the stop plate, and the limit plate is used to limit the falling position of the stop plate. The thrust shaft is rotatably arranged between the two lifting plates in front of the limit plate. A clamping groove for clamping the stop plate is arranged on the thrust shaft. One end of the thrust shaft penetrates through a lifting plate, and a handle for driving the thrust shaft to rotate is arranged on the thrust shaft outside the lifting plate. A baffle plate is arranged on the thrust shaft below the handle. The release swing arm is rotatably arranged on the lifting plate behind the baffle plate through a pin shaft. The front end of the release swing arm is in limit contact connection with the baffle plate, and the rear end of the release swing arm is connected with the hydrostatic pressure release device. The safety pin lock is arranged on the lifting plate corresponding to the position of the handle. The middle parts of the two cable stopper plates are arranged outside the two lifting plates below the front end of the hook through a pin shaft, and a limit rod is respectively arranged between the upper end and the lower end of the two cable stopper plates.
[0006] In the above lifeboat hook device with load, a clamping hole for clamping the limit rod is arranged on the lifting plate at the lower inner side of the hook.
[0007] In the above lifeboat hook device with load, an auxiliary lifting plate is arranged between the rear sides of the two lifting plates through a pin shaft, and a lifting hole is arranged on the upper surface of the auxiliary lifting plate.
[0008] The advantages of the present utility model compared with the prior art are as follows: After the lifeboat of the present utility model is released onto the water surface, the hydrostatic pressure release device drives the release swing arm to rotate, thereby releasing the rotation of the thrust shaft.
[0009] Then operate the handle to rotate the thrust shaft. When the thrust shaft rotates to a certain angle, the stop plate can freely fall into the groove of the thrust shaft. The torque generated by the upward pulling force of the steel wire rope on the hook is greater than the torque generated by the self-weight of the hook. As a result, the hook rotates backward, and the steel wire rope for lifting the lifeboat falls out of the hook, thereby realizing the load-carrying hook release to release the lifeboat onto the water surface.

[0013] As Figure 1 , Figure 2 and Figure 3 shown, a load-carrying hook device for a lifeboat, characterized in that it includes a bottom plate 1, a lifting plate 2, a hook 3, a stop plate 4, a limiting plate 5, a thrust shaft 6, a handle 7, a baffle 8, a release swing arm 9, a safety pin lock 10, a cable stop plate 11, a limiting rod 12, a pin shaft 13, a hydrostatic pressure release device 14 and an auxiliary lifting plate 15;
[0014] On the bottom plate 1, two lifting plates 2 are arranged in parallel. The lifting hook 3 is rotatably arranged between the upper ends of the two lifting plates 2 through a pin shaft 13. The rear end of the stop plate 4 is rotatably arranged between the two lifting plates 2 at the lower end of the lifting hook 3 through a pin shaft 13. A groove 4.1 for clamping the lifting hook 3 is arranged on the upper end surface of the stop plate 4. A limiting plate 5 is arranged between the two lifting plates 2 below the rear of the stop plate 4. The limiting plate 2 is used to limit the falling position of the stop plate 4. A thrust shaft 6 is rotatably arranged between the two lifting plates 2 in front of the limiting plate 5. A clamping groove 6.1 for clamping the stop plate 4 is arranged on the thrust shaft 6. One end of the thrust shaft 6 penetrates through a lifting plate 2. A handle 7 for driving the thrust shaft 6 to rotate is arranged on the thrust shaft 6 outside the lifting plate 2. A baffle 8 is arranged on the thrust shaft 6 below the handle 7. The release swing arm 9 is rotatably arranged on the lifting plate 2 behind the baffle 8 through a pin shaft 13. The front end of the release swing arm 9 is in limiting contact connection with the baffle 8. The rear end of the release swing arm 9 is connected with the hydrostatic release unit 14. A safety pin lock 10 is arranged on the lifting plate 2 corresponding to the position of the handle 7. The middle parts of the two cable stoppers 11 are arranged outside the two lifting plates 2 below the front end of the lifting hook 3 through a pin shaft 13. A limiting rod 12 is arranged between the upper end and the lower end of each of the two cable stoppers 11 respectively. A clamping hole 2.1 for clamping the limiting rod 12 is arranged on the lifting plate 2 at the inner lower end of the lifting hook 3. An auxiliary lifting plate 15 is arranged between the rear sides of the two lifting plates 2 through a pin shaft 13. A lifting hole 15.1 is arranged on the upper surface of the auxiliary lifting plate 15.
[0015] The working principle of the utility model is as follows: The utility model is arranged on the rescue boat through the bottom plate 1, and the hydrostatic release unit 14 is located outside the bottom of the rescue boat. When releasing the rescue boat, first put the lifting wire rope of the boat onto the lifting hook 3, and then place the rescue boat on the sea surface. When the hydrostatic release unit 14 contacts the water surface, it pushes the release swing arm 9 upward to rotate counterclockwise. The front end of the release swing arm 9 is disengaged from the limiting contact with the baffle 8. Then open the safety pin lock 10 and rotate the handle 7 counterclockwise. The thrust shaft 6 rotates. After the thrust shaft 6 rotates to a certain angle, the stop plate 4 can freely fall into the groove 6.1 of the thrust shaft 6, and the lower end of the lifting hook 3 is disengaged from the limit in the groove 4.1. Thus, the torque generated by the upward pulling force of the wire rope on the lifting hook 3 is greater than the torque generated by the self-weight of the lifting hook 3. As a result, the lifting hook 3 rotates backward, and the wire rope for lifting the lifeboat falls out of the lifting hook 3. Thus, the lifeboat is released onto the water surface by load-carrying hook disengagement.
