Description

Technical Field

[0001] The invention belongs to the field of ship towing equipment, and in particular relates to a ship quick-release towing device. Background Art

[0002] A towing device is a key device specially designed for use in marine environments to connect to ships or other offshore structures for towing operations. It is usually installed at a specific location on the hull, such as the bow or stern, to facilitate the performance of various types of towing tasks. Towing devices are widely used in a variety of scenarios, including but not limited to: emergency rescue operations, auxiliary navigation (such as guiding large ships through narrow waterways), offshore construction support, and scientific research. Its main function is to provide a safe and reliable connection point to ensure that the towed object can smoothly follow the movement of the tugboat.

[0003] At present, on many small vessels (such as lifeboats and patrol boats), the most commonly used towing method is to use traditional towing piles. Although this method is simple and direct, it exposes some obvious shortcomings in the actual operation process that requires quick release. When the towed object needs to be quickly separated, the conventional practice is to manually untie the fixed rope. However, under tense operating conditions, this untying process is often time-consuming and prone to errors. Especially in bad weather or when the towing force is large, manual disconnection may pose a potential threat to the operator, and improper handling may also cause accidental injuries or even more serious accidents. Faced with complex and changeable sea conditions (such as large waves, strong winds, etc.), traditional towing systems are difficult to ensure efficient and accurate completion of instant separation tasks, thus affecting the overall emergency response efficiency. Summary of the invention

[0004] The present invention aims to provide a quick-release towing device for a ship, so as to solve the technical problem of quick release of a towed object by a ship.

[0005] To achieve the above-mentioned purpose, the specific technical solution of a quick-release towing device for a ship of the present invention is as follows:

[0006] A quick-release towing device for a ship comprises a base, a towing frame with one end connected to the base and the other end extending outward, a hook rotatably connected to the extended end of the towing frame, and a release structure and a locking block connected to the towing frame;

[0007] The hook is concavely provided with a towing groove for placing the towing rope, and the towing groove forms a towing opening on the surface of the hook. The locking block is arranged along the towing opening to achieve the closure of the towing groove. The release structure realizes the locking and release of the hook rotation. After the release structure releases the hook, the hook rotates to open the towing opening.

[0008] As a further improvement of the present invention, the release structure includes a release rod rotatably connected to the towing frame, and a release block connected to the release rod; the release rod rotates to drive the release block to abut against the hook to lock the hook.

[0009] As a further improvement of the present invention, the release rod includes a manipulation part and a connecting part, the manipulation part and the connecting part are connected at a certain angle, the bent connection is rotatably connected to the towing frame through a connecting component, the connecting part is connected to the release block, and the manipulation part rotates to drive the release block to abut against the hook.

[0010] As a further improvement of the present invention, the control part protrudes relative to the towing frame to facilitate rotation operation, and the control part is remotely controlled by connecting a control rope.

[0011] As a further improvement of the present invention, the control part is provided with a control hole for connecting a control rope to realize remote control.

[0012] As a further improvement of the present invention, a locking groove is concavely provided in the hook, and one end of the release block enters the locking groove to lock the hook.

[0013] As a further improvement of the present invention, the base is provided with a through hole, which is connected to a connecting lug or a connecting pile by bolts to achieve installation on the side of the hull or the deck.

[0014] As a further improvement of the present invention, the inner shape of the locking block facing the hook matches the outer circumference of the hook, and the outer circumference of the hook is circular.

[0015] Beneficial effects:

[0016] The device of the present invention adopts a design that combines a rotatable hook and a locking block in the released state, so that when it is necessary to separate the towed object, the towing opening can be quickly opened by simply rotating the release lever, realizing a truly "one-button" quick release. This design greatly simplifies the complex steps in the traditional untying process and improves the emergency response speed through the method of inserting and removing the sleeve.

[0017] The device is equipped with a special locking mechanism to ensure that the hook will not open accidentally during towing, ensuring the safety of the connection; at the same time, when performing the release action, since the entire process can be carried out away from the danger zone (such as through remote control), the risks to the operator caused by direct contact are effectively avoided.

[0018] The quick-release towing device provided by the present invention can work normally no matter it is in a stationary state or under a large pulling force, and can still maintain good performance and show a high environmental adaptability, especially in severe sea conditions.

[0019] It supports two release modes: loaded and unloaded. Under unloaded conditions, the tow rope can be taken out or inserted by manually rotating the hook. When in a loaded state, the hook rotates under the tension of the towed object by turning the release lever, and the towed object is released urgently, providing strong technical support for high-risk tasks such as maritime rescue.

[0020] The base through hole adopts a standard interface design, which is convenient for flexible adjustment of the installation position according to actual needs; thanks to its universal interface setting, the present invention is not only suitable for various types of small boats, but also can be used well with other common sailing equipment, further expanding the scope of application.

[0021] In summary, the quick-release towing device for ships proposed in the present invention, by virtue of its innovation, practicality and reliability, not only improves the efficiency of offshore operations but also greatly enhances the safety factor, and is of great significance for promoting technological progress in related fields.

DETAILED DESCRIPTION

[0028] In order to better understand the purpose, structure and function of the present invention, a quick-release towing device for a ship of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0029] Implementation example:

[0030] like Figure 1 A quick-release towing device for a ship is shown, which is connected to the boat through a base 100, a towing frame 200 is fixed to the side of the base 100 by bolts and extends outward, a hook 300 is rotatably connected to the extended end of the base 100, a release structure 400 is provided in the middle of the towing frame 200, and the locking and releasing states of the hook 300 are achieved by pulling the release structure 400, a towing groove 310 is provided on the hook 300, a towing rope 600 is inserted into the towing groove 310, and a locking block 500 closes the towing opening 311 to achieve the placement of the towing rope 600 on the hook 300.

[0031] like Figure 2-3 As shown, in this embodiment, the hook 300 is circular, and the outer peripheral surface is concavely provided with a towing groove 310 and a locking groove 320. The towing groove 310 is used to place the connecting towing rope 600, and the locking groove 320 cooperates with the release structure 400 to achieve the locking of the hook 300. The towing groove forms a towing opening on the outer peripheral surface of the hook, and a locking block is provided outside the towing opening. The locking block 500 is fixedly connected to the towing frame 200 and extends toward the towing opening 311. The inner shape matches the outer periphery of the hook 300. When the hook 300 is locked, the towing opening 311 is closed, and the towing rope 600 is closed in the towing groove 310.

[0032] The release structure 400 includes a release rod 410 and a release block 420. The release rod 410 is a U-shaped structure with long and short sides. The long side is a control part 411, which is exposed relative to the towing frame 200 to facilitate subsequent rotation operations; the short side is a connecting part 412, which is used to connect with the release block 420; the bent connecting part is rotatably connected to the towing frame 200 through a connecting component, which is a pin connection in this embodiment. One end of the release block 420 is connected to the release rod 410, and the other end extends into the locking groove 320 of the hook 300 to lock the hook 300. A control hole 413 is set at the top of the control part 411, and the release operation of the release structure 400 is realized remotely by connecting the control rope 700. In the default state, the release rod 410 controls the release block 420 in the locking groove 320 under the restriction of the elastic component. The release rod 410 is rotated to make the release block 420 disengage from the locking groove 320, releasing the hook 300, so that the hook 300 is in a rotatable state; the pulling force on the release rod 410 is cancelled, and under the restoring action of the elastic component, the release rod 410 returns to the initial position, the release block 420 enters the locking groove 320, and the hook 300 enters the locked state.

[0033] like Figure 4-5As shown, when in use, first pull the release lever 410 to release the hook 300 to enter a rotatable state, rotate the hook 300 to insert the towing rope 600 into the towing groove 310, rotate the hook 300 until the locking block 500 closes the towing opening 311, loosen the release lever 410, and return the release lever 410 to the default state. At this time, the release block 420 enters the locking groove 320, the hook 300 enters a locked state, and the towing rope cannot be separated from the towing groove 310. When quick release is required, only the release lever 410 needs to be pulled, and the hook 300 enters a rotatable state. Under the pulling force of the towing rope 600, the hook 300 automatically rotates, and after rotating to a certain angle, the towing rope 600 automatically detaches. In an emergency, even under high load conditions, smooth and reliable release can be achieved without additional manual intervention, further reducing operation time and potential operation risks.

[0034] The device of the present invention realizes remote control by connecting the rope through the control hole, so that in an emergency, the hook can be quickly released from the towing rope by pulling the release rod. Remote control avoids direct contact between the operator and the equipment, reducing potential safety risks, especially in severe sea conditions or high load conditions. In the released state, the hook can automatically rotate to open the towing opening under the action of the towing rope tension, so that the towing rope is automatically detached. The automatic rotation release function ensures smooth and reliable release even under high load conditions without additional manual intervention. The traditional untying process is often cumbersome and time-consuming, while the device can complete the release action by simply rotating the release rod, greatly simplifying the operation steps. Whether it is daily use or rapid response in an emergency, it can significantly improve work efficiency and reduce the possibility of misoperation. In the locked state, the locking block tightly closes the towing opening to ensure that the towing rope is firmly placed in the towing groove to prevent accidental falling off. During the release process, the recovery action of the elastic component ensures that the release rod can quickly return to the initial position and re-lock the hook, thereby enhancing the stability of the system. Whether in a static state or under a large pulling force, the device can work normally and show good environmental adaptability. It is particularly suitable for complex and changeable sea conditions, such as big waves and strong winds, and can still maintain efficient and stable performance. The base through-hole adopts a standard interface design, which is convenient for flexible adjustment of the installation position and suitable for various types of ships. The modular component design facilitates later maintenance and replacement of damaged parts, reducing maintenance costs. Regardless of whether there is a load, the device can achieve stable and reliable release, providing strong technical support for high-risk tasks such as maritime rescue. It can be used for daily inspection and maintenance under no-load conditions, and can respond to the needs of rapid unhooking in emergency situations under full-load working conditions.
