Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ship, especially a ship lifeboat fixed hook. BACKGROUND

[0002] Ship is an important carrier of human civilization development, and has been an important tool connecting various places at sea since ancient times. With the passage of time, ship technology has been continuously progressing, from the initial single wooden boat to modern large oil tankers, passenger ships, cargo ships and other complex ships. Modern ships are not only transport tools, but also important foundations for globalization and international exchanges. The design and manufacture of ships involve multiple fields, including marine engineering, mechanical manufacturing, material science, electronic technology, etc.

[0003] Lifeboat is a device used for rescue, emergency sea or special task execution in emergency situations of ship. Due to its special application scenario, lifeboat needs to have high strength, durability and reliability to ensure normal work in severe sea conditions.

[0004] Fixed hook is an important device connecting lifeboat with rescue ship or mother ship, and its main functions include:

[0005] Fixed connection: ensures stable connection between lifeboat and mother ship, prevents loosening or falling;

[0006] Load bearing: can bear certain static load and dynamic overload;

[0007] Adapt to sea conditions: still maintain stable connection in severe sea conditions (such as strong wind, surge, high wave).

[0008] Fixed hook is an important connecting device between ship lifeboat and rescue ship, and its design and performance are directly related to the success or failure of rescue work. With the progress of ship technology and the complexity of rescue tasks, the design of fixed hook is also continuously optimized, striving to provide higher stability and reliability in dynamic environment.

[0009] However, the existing fixed hook is easy to separate from the hooked object during use, causing the hooked object to fall, and the fixed hook needs to be operated by the operator at the hooked place during use, which is very inconvenient and cannot realize automatic operation. UTILITY MODEL CONTENTS

[0010] In view of the deficiencies in the prior art, the utility model provides a ship lifeboat fixed hook.

[0011] The purpose of this utility model is achieved as follows: a fixed hook for a ship's lifeboat includes a hook component, a linkage plate movably connected to the upper end of the hook component, one end of the linkage plate being positioned, a crank rod movably connected to the other end of the linkage plate, a pull rope connected to the other end of the crank rod, and a return spring fixedly connected to one side of the linkage plate.

[0012] Furthermore, it also includes a first plate and a second plate, with a welding plate welded between the two sides of the first plate and the second plate.

[0013] Furthermore, the upper ends of the first plate and the second plate are provided with connecting holes, and the hook, the linkage plate, and the crank rod are movably positioned between the first plate and the second plate.

[0014] Furthermore, one end of the hook is movably connected to the second plate via a pin, and one end of the linkage plate is positioned and connected to the second plate via a pin. The second plate and the first plate are provided with two arc-shaped grooves and a straight groove.

[0015] Furthermore, the connection between the hook and the linkage plate is movably connected by a pin that is movably located inside the arc-shaped groove, and the connection between the linkage plate and the crank rod is movably connected by a pin that is movably located inside the arc-shaped groove. The upper end of the crank rod is provided with a pin that is movably installed in the straight groove.

[0016] Furthermore, an adjustment groove is provided in the middle of the crank arm, and a positioning shaft is positioned and installed in the adjustment groove in the middle of the crank arm.

[0017] Furthermore, guide wheels are installed at one corner of the upper end of the first plate and the second plate, one end of the pull rope is fixedly connected to one end of the crank rod, and the pull rope is wrapped around one side of the guide wheel.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In use, this utility model connects the hook via a crank and a linkage plate. One end of the linkage plate is movable to maintain its balance and stability. A pull rope connects to one end of the crank, so that when the rope pulls the crank, it pulls the linkage plate, which in turn pulls the hook, allowing it to unfold and retract. The unfolded hook facilitates the locking and connection of suspended objects, and the retracted hook prevents suspended objects from falling off.

[0020] Furthermore, a reset spring is fixed on one side of the linkage plate. The reset spring pulls the linkage plate, so that when the pull rope stops pulling, the linkage plate can be controlled to be pulled back, thereby keeping the hook closed and preventing the suspended object from falling off.
