[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-3This utility model discloses a self-balancing boarding ladder, including a mounting base 1. Two fixed bases 2 are symmetrically fixedly mounted on the upper end of the mounting base 1. A fixed column 6 is fixedly mounted on the front end of one side of each of the two fixed bases 2. A rotating rod 7 is rotatably mounted on each fixed column 6. A buffer assembly is provided on the rotating rod 7, which includes a sliding rod 21, a slider 22, a spring 23, a second U-shaped block 24, a lifting frame 9, a fixed block 18, a first U-shaped block 17, and a mounting rod 19. Four slots 20 are symmetrically opened on one side of each rotating rod 7. A sliding rod 21 is fixedly mounted in each of the four slots 20, and a slider 22 is slidably mounted on each of the sliding rods 21. A spring is fixedly mounted on one side of each of the four slots 20. 23. The other end of each spring 23 is fixedly installed on one side of each slider 22. Each spring 23 is sleeved on the slider 21. A U-shaped block 24 is fixedly installed on one end of each slider 22. Two fixing blocks 18 are symmetrically fixedly installed on both sides of the lifting frame 9. Two U-shaped blocks 17 are symmetrically fixedly installed on one end of each fixing block 18. An installation rod 19 is rotatably installed inside each U-shaped block 17. The other end of each installation rod 19 is rotatably installed inside the U-shaped block 24. Two guardrails 11 are symmetrically fixedly installed on the upper end of the lifting frame 9. Two fixing rings 10 are symmetrically fixedly installed on the front end of the lifting frame 9. Hooks 8 are fixedly installed at the bottom of the lifting frame 9 and the rotating rod 7. The mounting base 1 and the two fixed bases 2 form a stable connection foundation, providing solid support for the entire equipment and ensuring the installation stability of the equipment under various working conditions. The fixed column 6 at the front end of one side of the fixed base 2 provides a reliable rotation fulcrum for the rotating rod 7, allowing the rotating rod 7 to flexibly adjust its angle to adapt to different usage requirements. The buffer assembly on the rotating rod 7 provides precise sliding guidance for the slider 22 through the slide rod 21 in the slot 20. The spring 23 on one side of the slider 22, which is sleeved on the slide rod 21, can effectively absorb and buffer the impact force generated by the swaying of the lifting frame 9 due to the ship's movement through elastic deformation. At the same time, the U-shaped block 24 of the slider 22 and the U-shaped block 17 on the fixed blocks 18 on both sides of the lifting frame 9 are connected by installation. The rod 19 forms a rotating connection structure. This multi-node rotation, combined with the elastic buffer of the spring 23, can dissipate sway energy in multiple directions and angles, greatly improving the balance and stability of the hoisting frame 9 and reducing the bumpy feeling when personnel pass through. In addition, the two guardrails 11 at the top of the hoisting frame 9 can effectively prevent personnel from falling accidentally, significantly improving the safety of the boarding process. The two fixing rings 10 at the front end can be easily connected to the traction device, providing a reliable connection point for the lifting and adjusting of the hoisting frame 9. The hooks 8 at the bottom of the hoisting frame 9 and the rotating rod 7 are fixed to the hull, further reinforcing the overall structure and preventing excessive swaying of the equipment under severe conditions such as strong winds, thus fully ensuring the safety and reliability of the boarding operation. Two support frames 5 are fixedly installed on the upper ends of two fixed bases 2. A rotating column 15 is rotatably installed in the middle of the two support frames 5. Two winding wheels 16 are symmetrically fixedly installed on the rotating column 15. One end of the rotating column 15 passes through a support frame 5 and is connected to a motor 4 via a coupling. The motor 4 is fixedly installed on one side of the support frame 5. A motor brake 3 is provided at the end of the motor 4. Mounting columns 14 are fixedly installed on the upper ends of the two support frames 5. Two fixed pulleys 13 are symmetrically rotatably installed on the mounting columns 14. Steel ropes 12 are provided on both winding wheels 16. The steel ropes 12 are fitted together and installed... On the fixed pulley 13, the other end of the steel rope 12 is fixedly installed on the fixed ring 10. In use, firstly, the two support frames 5 at the upper end of the fixed seat 2 form a high-strength support frame, providing a stable installation foundation for core transmission components such as the rotating column 15 and the winding wheel 16, ensuring the structural rigidity of the lifting system during operation and avoiding the impact of deformation due to force on the adjustment accuracy; the rotating column 15 is set through the middle of the support frame 5, and its two ends are evenly stressed. With the two symmetrically fixed winding wheels 16, the two steel ropes 12 can be wound and released simultaneously, realizing the smooth lifting and lowering of the hoisting frame 9, effectively preventing the tilting problem caused by unilateral force. Secondly, the power transmission design is efficient and reliable. The motor 4 is directly connected to the rotating column 15 through a coupling, with low power transmission loss, and can accurately drive the winding wheel 16. Moreover, the motor 4 is fixed on one side of the support frame 5, with strong installation stability; the motor brake 3 at the end of the motor 4 can quickly brake and lock after lifting and lowering to the correct position, preventing the hoisting frame 9 from accidentally sliding due to gravity or external force, and significantly improving positioning safety.

[0018] Working principle: When a self-balancing boarding ladder is put into use, the motor 4 fixed to the upper fixed base 2 of the mounting base 1 drives the rotating column 15 to rotate, which drives the winding wheel 16 on it to wind up and unwind the steel rope 12. The steel rope 12 is guided by the fixed pulley 13 on the mounting column 14 and then connected to the fixed ring 10 of the hoisting frame 9 to realize the lifting and lowering of the hoisting frame 9. The motor brake 3 at the end of the motor 4 can realize braking and positioning. The rotating rod 7 rotatably installed on the fixed column 6 on one side of the fixed base 2 is connected to the hoisting frame 9 through a buffer assembly. The slider 22 on the sliding rod 21 in the slot 20 of the rotating rod 7 cooperates with the spring 23 to form a buffer. The U-shaped block 24 of the slider 22 is rotatably connected to the U-shaped block 17 of the fixed block 18 of the hoisting frame 9 through the mounting rod 19, which can buffer the swaying of the hoisting frame 9. The hook 8 at the bottom of the rotating rod 7 and the hoisting frame 9 assists in fixation. The guardrail 11 at the upper end of the hoisting frame 9 ensures safety.

[0019] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
