[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0028] Example 1

[0029] Reference Figure 1-6 A lifting device for a shipborne rejection system includes a base 1, a support column 2 is fixedly installed on the top of the base 1, a personnel detection mechanism is provided inside the base 1, a boom 3 is fixedly connected to the top of the support column 2, a slide rail 4 is fixedly installed on the side wall of the boom 3, a lateral migration mechanism is provided inside the boom 3, a translation slider 6 is slidably installed on the upper end of the slide rail 4, two slide rods 5 are fixedly connected to the side of the translation slider 6 close to the boom 3, a winding drum 7 is fixedly connected to the bottom wall of the boom 3, a cargo lifting mechanism is provided inside the winding drum 7, a rejection drive drum 8 is fixedly connected to the outside of the winding drum 7, a rejection feedback mechanism is provided inside the rejection drive drum 8, and a motor 9 is fixedly connected to the outside of the rejection drive drum 8;

[0030] The lateral migration mechanism includes two slide grooves 31 provided inside the boom 3, the inner walls of the slide grooves 31 are fixedly connected to first electromagnets 34, the other ends of the first electromagnets 34 are fixedly connected to first springs 33, the other ends of the first springs 33 are fixedly mounted with first permanent magnets 32, and the other ends of the first permanent magnets 32 are fixedly connected to the slide bar 5. When the cargo is hoisted and migrated horizontally, the first electromagnet 34 is first turned on. Under the action of the magnetic force of the first electromagnet 34, the first permanent magnet 32 ​​slides toward the inside of the slide groove 31, thereby compressing the first spring 33, and then causing the translation slider 6 to slide along the boom 3. When it runs to the target area of ​​the migration end point, the lifting mechanism for lifting cargo is turned on to realize the vertical transportation of the cargo.

[0031] A connecting arm 10 is fixedly installed on the bottom wall of the translation slider 6, and a pulley 11 is fixedly connected to the inside of the connecting arm 10. A traction rope 12 is sleeved on the inside of the pulley 11, and a hook 13 is fixedly connected to the lower end of the traction rope 12. The other end of the traction rope 12 extends to the inside of the winding drum 7.

[0032] Example 2

[0033] like Figure 1-6As shown, this embodiment is basically the same as embodiment 1. Preferably, the cargo lifting mechanism includes a winding roller 71 fixedly connected to the inside of the winding drum 7, the traction rope 12 is wound and sleeved on the winding roller 71, and the end of the traction rope 12 is fixedly connected to the inner wall of the winding roller 71 through a positioning block 73. A positioning groove 72 is provided on the outer wall of the winding roller 71. When the cargo is transported in the vertical direction, the cargo to be transported is first hung on the hook 13, and then the motor 9 is turned on. One end of the output shaft of the motor 9 drives the rotating rod 91 to rotate, thereby driving the winding roller 71 to rotate synchronously, so that the traction rope 12 is wound around the upper end of the winding roller 71, and then the traction rope 12 slides along the pulley 11 to achieve the lifting of the cargo. When the lateral transfer mechanism runs the cargo to the end point, the motor 9 is turned on to rotate it in the opposite direction, so that the upper end of the winding roller 71 rotates in the opposite direction, thereby achieving the release of the cargo. The lateral transfer mechanism and the cargo lifting mechanism are used to achieve rapid lifting and migration of the cargo. The degree of automation is high, and rapid lifting and migration can be achieved, which significantly improves the cargo handling efficiency.

[0034] The positioning grooves 72 are arranged at equal intervals along the outer wall of the winding roller 71. A rotating rod 91 is fixedly connected to the center of the positioning groove 72. The other end of the rotating rod 91 is fixedly connected to the output shaft of the motor 9 to ensure that one end of the output shaft of the motor 9 drives the rotating rod 91 and the winding roller 71 to rotate synchronously.

[0035] Example 3

[0036] like Figure 1-6 As shown, this embodiment is basically the same as embodiment 1. Preferably, the rejection feedback mechanism includes a second electromagnet 81 fixedly connected to the inner wall of the rejection drive cylinder 8 near the winding roller 71. The other end of the second electromagnet 81 is fixedly installed with a second spring 82, and the other end of the second spring 82 is fixedly connected with a second permanent magnet 83. When the rejection feedback mechanism is not turned on, the rejection drive cylinder 8 and the winding roller 71 are as shown in FIG. Figure 5 As shown, when the rejection feedback mechanism is turned on, the second electromagnet 81 is energized, and under the action of the repulsive force of the magnetic force, the second permanent magnet 83 slides toward the side away from the second electromagnet 81, causing the second spring 82 to extend, and then causing the second permanent magnet 83 to slide to the inside of the positioning groove 72, thereby realizing rejection self-locking. The rejection feedback mechanism is used to timely interrupt the lifting and migration of goods during the lifting process. At the same time, the coordination between the winding roller 71, the positioning groove 72, the second electromagnet 81 and the second permanent magnet 83 is used to achieve the cut-off and self-locking of the goods during the lifting process, thereby reducing the shaking generated during the lifting of the goods, thereby improving the safety of the goods during the lifting process.

[0037] Example 4

[0038] like Figure 1-6As shown, this embodiment is basically the same as embodiment 1. Preferably, the personnel detection mechanism includes a limiting groove 15 opened inside the base 1. The limiting groove 15 is a rectangular groove. The limiting groove 15 is located on one side of the support column 2. An elastic limiting sleeve 14 is slidably installed inside the limiting groove 15. The elastic limiting sleeve 14 is set as a rectangular sleeve. The bottom wall of the elastic limiting sleeve 14 is fixedly connected with an elastic airbag 16. The elastic airbags 16 are arranged at equal intervals along the bottom wall of the elastic limiting sleeve 14. The other end of the elastic airbag 16 is fixedly installed with a piezoelectric ceramic 17. The other end of the piezoelectric ceramic 17 is fixedly connected to the inner bottom wall of the limiting groove 15. When the goods are hoisted, once a person steps on the upper end of the elastic limiting sleeve 14, the elastic limiting sleeve 1 4 slides down along the inner portion of the limit groove 15, thereby compressing the elastic airbag 16 at the bottom of the elastic limit sleeve 14, thereby generating a piezoelectric current on the piezoelectric ceramic 17. After the piezoelectric current is generated, it is fed back to the second electromagnet 81 on the rejection feedback mechanism, thereby driving the hoisting to be cut off, ensuring the synchronous opening of the rejection feedback mechanism. The elastic personnel detection mechanism realizes real-time monitoring of personnel passing under the hoisting area. At the same time, the coordination between the elastic limit sleeve 14, the limit groove 15, the elastic airbag 16 and the piezoelectric ceramic 17 realizes real-time monitoring of personnel under the hoisting area, achieving the effect of timely feedback to the rejection system according to the passage of personnel, improving the safety during the hoisting process, and ensuring the life safety of the crew;

[0039] The first permanent magnet 32 ​​and the first electromagnet 34 have different magnetic properties, ensuring that the first permanent magnet 32 ​​slides toward the first electromagnet 34 under the action of magnetic attraction, and the second electromagnet 81 and the second permanent magnet 83 have the same magnetic properties, ensuring that the second permanent magnet 83 slides away from the side of the second electromagnet 81 under the action of magnetic repulsion. When the first electromagnet 34 and the second electromagnet 81 are disconnected, the originally deformed first spring 33 and the second spring 82 return to their initial state, and the second permanent magnet 83 can slide into the inside of the positioning groove 72, ensuring that after the second electromagnet 81 is turned on, the second permanent magnet 83 slides into the positioning groove 72 under the action of magnetic repulsion, thereby realizing the rejection and self-locking of the winding roller 71, and realizing the timely interruption of the lifting and migration of goods during the lifting process through the rejection feedback mechanism. At the same time, the coordination between the winding roller 71, the positioning groove 72, the second electromagnet 81 and the second permanent magnet 83 is realized to achieve the cut-off and self-locking of the goods during the lifting process, thereby reducing the shaking generated during the lifting of goods, thereby improving the safety of the goods during the lifting process.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
