[0005] 2. When the ship is hit by wind and waves, the pilot ladder is tilted due to the force when the ship is rocked, and the pilot is likely to fall into the water;

[0006] 3. The ropes and wooden steps of the pilot ladder are prone to aging and deformation, which poses a high risk;

[0007] 4. Quality defects. Improper operation by the crew resulted in the pilot ladder not being securely placed, which made it easy for the pilot to fall when climbing up;

[0047] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0048] Embodiment 1:

[0049] Please refer to Figure 1-Figure 7 , a pilot boarding and disembarking device, comprising:

[0050] Elevator 3, the elevator 3 is fixed on the target ship 1;

[0051] A telescopic support 4, wherein the telescopic support 4 is fixed on the pilot boat 2;

[0052] The sling 5 is arranged at a position between the elevator 3 and the telescopic support 4. One end of the sling 5 is fixedly connected to the elevator 3, and the other end of the sling 5 passes around the upper part of the telescopic support 4 and is detachably fixedly connected to the pilot boat 2 through a fixing member 6; wherein, in order to reduce the wear of the sling 5, the top of the telescopic support 4 is rotatably connected to a guide wheel 9, and the end of the sling 5 away from the elevator 3 passes around the upper part of the guide wheel 9 and is detachably connected to the fixing member 6.

[0053] A traction rope 7 is arranged on the sling 5, one end of which is connected to the sling 5 by a hook. A traction assembly 8 is arranged on the top of the elevator 3, and the other end of the traction rope 7 is wound up by the traction assembly 8.

[0054] Specifically, the lift 3 includes a lifting rod 14, the lower end of which is fixedly connected to the target ship 1, a traction frame 15 is provided at the upper end of the lifting rod 14, one end of which is rotatably connected to the top of the lifting rod 14, a lifting frame 16 is fixedly connected to the lower part of the traction frame 15, the lower part of the lifting frame 16 is movably connected to the lifting rod 14, and the traction assembly 8 is fixed to the upper end of the traction frame 15. Among them, two rotating wheels 17 are rotatably connected to the inner side of the lower end of the lifting frame 16, and grooves are provided on the circumference of the rotating wheel 17. A guide rail 18 is fixed to the outer side of the lifting rod 14 and at a position corresponding to the rotating wheel 17, and the rotating wheel 17 is rollingly connected to the guide rail 18 through the groove.

[0055] It can be seen that the device is composed of the main components such as the elevator 3, the traction assembly 8, the telescopic support 4, the traction rope 7, and the sling 5. The elevator 3 is fixed on the target ship 1. When the pilot ship 2 approaches, the traction assembly 8 is firmly connected to the pilot ship 2 through the sling 5. The traction assembly 8 has the function of retracting and releasing the traction rope 7. The traction rope 7 is connected to the sling 5 through a slidable hook. The device is powered by a power supply, and the traction assembly 8 is started to realize the traction function.

[0056] When the pilot ladder is working, the power is first turned on, and the traction assembly 8 selects the mode of releasing the traction rope 7, and then the hook at one end of the traction rope 7 slides along the sling 5 to the pilot boat 2. The pilot then wears a safety rope connected to the hook, and finally the retraction function of the traction assembly 8 is activated, and the pilot is towed to the target ship 1 by retracting the traction rope 7, completing the pilot boarding process.

[0057] Furthermore, the traction assembly 8 includes a mounting plate 19, the mounting plate 19 is fixedly connected to the traction frame 15 by screws, a driving motor 20 is fixedly connected to one end of the top of the mounting plate 19, a transmission box 22 is arranged at the other end of the top of the mounting plate 19, the output end of the driving motor 20 is connected to the transmission box 22 through a coupling 21, a winch 23 is arranged on the side of the transmission box 22, and the end of the traction rope 7 away from the telescopic support 4 is wound on the outside of the winch 23. It can be seen that by starting the driving motor 20 to drive the transmission box 22 to move through the coupling 21, the winch 23 is driven to rotate forward and reverse through the transmission of the transmission box 22, thereby realizing the process of retracting and releasing the traction rope 7. Among them, the height position adjustment of the two ends of the sling 5 is realized by adjusting the lifting and lowering of the elevator 3 and the telescopic support 4.

[0058] Embodiment 2:

[0059] The pilot boarding and disembarking device provided in Example 1 is further optimized. Specifically, Figure 4As shown, the fixing member 6 includes a fixing base 10, which is fixedly connected to the pilot boat 2. The upper end of the fixing base 10 is laterally rotatably connected to a connecting shaft 11. A connector 12 is also provided on the upper part of the fixing base 10. The lower end of the connector 12 is threadedly connected to a connecting arm 13. The lower end of the connecting arm 13 is hook-shaped. The lower part of the connecting arm 13 is sleeved on the outside of the connecting shaft 11. The end of the sling 5 away from the elevator 3 is detachably connected to the upper part of the connector 12.

[0060] Through the above structural design, the connection of the sling 5 is more convenient, fast and stable.

[0061] Embodiment 3:

[0062] The pilot boarding and disembarking device provided in Example 1 is further optimized. Specifically, Figure 8 As shown, the transmission box 22 includes a box body 24, and a worm 25 is laterally rotatably connected to the inner lower part of the box body 24, one end of the worm 25 is connected to the coupling 21, and a transmission rod 26 is longitudinally arranged on the inner upper part of the box body 24, both ends of the transmission rod 26 are rotatably connected to the box body 24 through a bearing seat 28, one end of the transmission rod 26 is fixedly connected to the transmission box 22, and a worm wheel 27 is fixedly connected to the transmission rod 26, and the worm wheel 27 is cooperatively connected to the worm 25.

[0063] Through the above structural design, it can be known that when the driving motor 20 is started, the worm 25 is driven to rotate through the coupling 21, and when the worm 25 rotates, it drives the worm wheel 27 to rotate synchronously. Through the fixed connection between the worm wheel 27 and the transmission rod 26, when the worm wheel 27 rotates, the winch 23 is driven to rotate synchronously through the transmission rod 26, so that through the forward and reverse rotation of the driving motor 20, the winch 23 can achieve the effect of retracting and releasing the traction rope 7.
