Detailed Implementation

[0016] The following are specific implementation cases and appendices. Figure 1-4 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0017] An automatic lifting device for a torpedo tanker, such as Figure 1-4 As shown, it includes: a front support 11, a rear support 12, a first electric push rod 13, an L-shaped connecting seat 14, a hook chain 15, a locking plate 16, and a pressing mechanism; the front support 11 and the rear support 12 are both located on one side of the coupler 10, the first electric push rod 13 is hinged to the rear support 12, the L-shaped connecting seat 14 is hinged to the front support 11, and both ends of the L-shaped connecting seat 14 are respectively hinged to the telescopic end of the first electric push rod 13 and one end of the hook chain 15; one end of the locking plate 16 is connected to the hook chain 15. The other end of the hook chain 15 is hinged, and the other end of the locking plate 16 is connected to the locking pin of the car hook 10; the clamping mechanism includes: a bracket 17, a second electric push rod 18, a connecting part 19 and a pressure cover 20. The bracket 17 is set on one side of the front support 11. The second electric push rod 18 is fixed on the bracket 17. The telescopic end of the second electric push rod 18 is connected to one end of the connecting part 19. The other end of the connecting part 19 is connected to the pressure cover 20, and the pressure cover 20 is pressed on the top surface of the locking plate 16.

[0018] With the above structure, the extension and retraction of the first electric push rod 13 controls the movement of the hook chain 15, causing the hook 10 to automatically open or close. The second electric push rod 18 drives the pressure plate 20 to move, applying pressure to the locking plate 16 to ensure a stable connection of the hook 10 in the locked state and prevent accidental unlocking. The hinged design of the L-shaped connecting seat 14 with the front support 11 and the hook chain 15 improves the flexibility of the hook lifting or locking states, avoiding jamming due to angular deviations.

[0019] In the embodiments of this utility model, it further includes: a torsion spring 21, a hook head positioning pin 22, and a hook tongue positioning pin 23; the hook head positioning pin 22 and the hook tongue positioning pin 23 are respectively disposed on the hook head 101 and the hook tongue 102 of the car coupler 10, the torsion spring 21 is mounted on the car coupler 10, and the two ends of the torsion spring 21 are respectively connected to the hook head positioning pin 22 and the hook tongue positioning pin 23.

[0020] By connecting the two ends of the torsion spring 21 to the hook head positioning pin 22 and the hook tongue positioning pin 23 respectively, the torsion spring 21 plays an auxiliary role, helping the hook 10 to more easily reach the unlocked or fully open state.

[0021] In an embodiment of this utility model, it further includes: a mounting base 24, a first proximity switch 25, and a second proximity switch 26; the mounting base 24 is mounted on the coupler 10 and located above the torsion spring 21; the first proximity switch 25 is disposed on the mounting base 24, and the second proximity switch 26 is disposed on the hook tongue 102 of the coupler 10.

[0022] By using the first proximity switch 25 and the second proximity switch 26 together, the opening or closing status of the hook tongue 102 can be monitored in real time. When the first electric push rod 13 is operated, it controls the coupler 10 to perform hook unhooking or hook locking operations. When the first proximity switch 25 detects the position of the hook tongue 102, it sends a hook unhooking status signal to the controller. When the second proximity switch 26 detects the position of the hook tongue 102, it sends a hook locking status signal to the controller, thereby achieving precise monitoring of the status of the coupler 10.

[0025] When the second electric push rod 18 drives the connecting part 19 and the pressure cover 20 to move up and down, the slider seat moves along the moving groove 27, thereby guiding the movement of the connecting part 19 and the pressure cover 20, improving the stability of the pressure cover 20 during movement, and preventing the pressure cover 20 from shifting.

[0026] Implementation process: The extension and retraction of the first electric push rod 13 controls the movement of the hook chain 15, causing the hook 10 to automatically open or close. The second electric push rod 18 drives the pressure plate 20 to move, applying pressure to the locking plate 16 to ensure a stable connection of the hook 10 in the locked state and prevent accidental unlocking. The hinged design of the L-shaped connecting seat 14 with the front support 11 and the hook chain 15 improves the flexibility of the hook lifting or locking state and avoids jamming due to angle deviation. By connecting the two ends of the torsion spring 21 to the hook head positioning pin 22 and the hook tongue positioning pin 23 respectively, the torsion spring 21 plays an auxiliary role, helping the hook 10 to more easily reach the unlocked or fully open state. The first proximity switch 25 detects the hook disengagement state, and the second proximity switch 26 detects the hook locking state, thereby providing feedback on the connection status of the hook 10.
