[0014] 1. For the automatic hook device for a crane spreader, through the settings of the conveying device, workbench, slider, base, rotating seat, first electromagnet and second electromagnet, the hook device for the crane spreader has the effect of automatically hooking. When in use, the goods to be lifted are conveyed to one side of the workbench through the conveying device. At this time, the hanging ring on the upper surface of the goods is in the middle position. During lifting, the hoisting lower vehicle drives the spreader main body to move above the workbench. At this time, the staff simultaneously energizes the first electromagnet and the second electromagnet. After energization, a magnetic field will be generated inside the iron core, and the electrodes of the opposite faces of the first electromagnet and the second electromagnet are opposite. At this time, under the action of the magnetic field, the second electromagnet and the first electromagnet are adsorbed together, which plays a role in fixing the spreader main body. Then, the crane operator observes whether the spreader main body is directly facing the hanging ring. If it is found that the angle of the spreader main body is deviated, the crane operator controls the second servo motor to work through the remote controller. The second servo motor drives the driving gear to rotate. The driving gear meshes with the tooth groove, so that the rotating seat rotates on the upper surface of the base. During the rotation process, the limiting ring block on the lower surface of the rotating seat slides in the limiting ring groove on the upper surface of the base, which plays a role in limiting. Through the rotation of the rotating seat, the spreader main body above is driven to rotate until the spreader main body rotates to a position directly facing the hanging ring. Then, the operation of the first servo motor is controlled. The first servo motor drives the reciprocating lead screw to rotate, so that the slider threadedly connected to the surface of the reciprocating lead screw slides in the support leg, and then the slider slides to the leftmost end of the chute. During the movement, the spreader main body is driven to move together, so that the spreader main body is hooked onto the hanging ring. Finally, the power supply to the first electromagnet and the second electromagnet is stopped. At this time, the magnetic force disappears, and the spreader main body is hung on the hanging ring, and then the lifting operation can be carried out. The automatic hook device for the crane spreader can reduce the operation of hooking through the automatic hooking operation, achieving the purpose of releasing the labor force.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] Embodiment 1
[0022] Please refer to Figures 1 to 4, the present utility model provides a technical solution: an automatic hook device for a crane sling, which includes a conveying device 1 and a sling main body 20. The upper surface on the right side of the conveying device 1 is provided with a cargo 2, and a hanging ring 3 is fixedly connected to the upper surface of the cargo 2. A workbench 4 is installed on the right side of the conveying device 1, and support legs 5 are fixedly connected to the lower surface of the workbench 4. The cargo 2 is located at the rightmost end of the conveying device 1. The number of support legs 5 is four, and they are distributed in a rectangular array. A chute 6 is opened on the upper surface of the workbench 4, and a slider 9 is slidably connected to the surface of the chute 6. A first servo motor 7 is installed on the right side surface of the workbench 4, and a reciprocating lead screw 8 is fixedly connected to the output end of the first servo motor 7. Bearings are provided at the connections between both ends of the reciprocating lead screw 8 and the workbench 4. The slider 9 is threadedly connected to the surface of the reciprocating lead screw 8, and a support block 10 is fixedly connected to the upper surface of the slider 9. A base 11 is fixedly connected to the upper surface of the support block 10. A limit ring groove 13 is opened on the upper surface of the base 11, and a limit ring block 14 is fixedly connected to the lower surface of the rotating seat 12. The limit ring block 14 slides within the limit ring groove 13. The rotating seat 12 is rotatably connected to the upper surface of the base 11, and a first electromagnet 19 is installed on the upper surface of the rotating seat 12. A second electromagnet 21 is installed on the lower surface of the sling main body 20. A motor groove 15 is opened on the upper surface of the base 11, and a second servo motor 16 is installed on the surface of the motor groove 15. A driving gear 17 is fixedly connected to the output end of the second servo motor 16. A tooth groove 18 is opened on the lower surface of the rotating seat 12, and the driving gear 17 and the tooth groove 18 are in meshing transmission. The first electromagnet 19 and the second electromagnet 21 have the same size, and the electrodes of their opposite faces are opposite.
[0023] In order to achieve the purpose of releasing labor force, when in use, the goods 2 to be lifted are conveyed to one side of the workbench 4 on the conveying device 1. At this time, the hanging ring 3 on the upper surface of the goods 2 is in the middle position. When lifting, the hoisting undercarriage drives the hoist body 20 to move above the workbench 4. At this time, the staff simultaneously energizes the first electromagnet 19 and the second electromagnet 21. After energization, a magnetic field will be generated inside the iron core, and the opposite surfaces of the first electromagnet 19 and the second electromagnet 21 have opposite electrodes. At this time, under the action of the magnetic field, the second electromagnet 21 adsorbs to the first electromagnet 19, which plays a role in fixing the hoist body 20. Then, the crane operator observes whether the hoist body 20 is directly facing the hanging ring 3. If it is found that the angle of the hoist body 20 is deviated, the crane operator controls the second servo motor 16 to work through the remote controller. The second servo motor 16 drives the driving gear 17 to rotate. The driving gear 17 meshes with the tooth groove 18, so that the rotating seat 12 rotates on the upper surface of the base 11. During the rotation process, the limiting ring block 14 on the lower surface of the rotating seat 12 slides in the limiting ring groove 13 on the upper surface of the base 11, which plays a role in limiting. Through the rotation of the rotating seat 12, the hoist body 20 above is driven to rotate until the hoist body 20 rotates to a position directly facing the hanging ring 3. Then, the first servo motor 7 is controlled to work. The first servo motor 7 drives the reciprocating lead screw 8 to rotate, so that the slider 9 threadedly connected to the surface of the reciprocating lead screw 8 slides in the support leg 5, and then the slider 9 slides to the leftmost end of the chute 6. During the movement, the hoist body 20 is driven to move together, so that the hoist body 20 is hooked on the hanging ring 3. Finally, the power supply to the first electromagnet 19 and the second electromagnet 21 is stopped. At this time, the magnetic force disappears, and the hoist body 20 is hung on the hanging ring 3, and the lifting operation can be carried out. The automatic hooking device for the crane hoist can reduce the operation of hooking through the automatic hooking operation, achieving the purpose of releasing labor force.
