Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to an intelligent electromagnetic chuck crane. Background Technology

[0002] Electromagnetic chuck cranes utilize the magnetic properties of electromagnets when an electric current is applied to attract and lift metal objects to a designated location. When the current is cut off, the magnetism disappears, and the metal object is lowered. They are commonly used to lift regularly shaped objects such as sheet metal and beams. However, existing electromagnetic chuck cranes require operator guidance during lifting and lowering, resulting in lower operational precision. Furthermore, the electromagnetic chuck may not always adhere properly to the object, potentially causing significant impact on the lifting device and affecting operational stability. Additionally, the chuck may fall onto the object, causing the wire rope to slacken, compromising the safety of the lifting operation. Utility Model Content

[0003] The purpose of this invention is to provide an intelligent electromagnetic chuck crane that can ensure the accuracy of the electromagnetic chuck when it engages with an object, thereby improving the stability and safety of the lifting operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent electromagnetic chuck crane, comprising two end beams, with two main beams arranged between the end beams, a lifting trolley arranged on the main beams, a drum mechanism arranged on the lifting trolley, a lifting device arranged below the lifting trolley, the lifting device including a mounting frame, a movable pulley mounted on the top of the mounting frame, the movable pulley being connected to the drum mechanism via a wire rope, a plurality of connecting frames evenly arranged at the bottom of the mounting frame, an electromagnetic chuck arranged below the connecting frame, a vertically arranged sliding hole opened on the connecting frame, a contact switch arranged at the top of the sliding hole, the electromagnetic chuck including a mounting plate, a chuck arranged at the bottom of the mounting plate, a sliding plate arranged at the top of the mounting plate, the sliding plate being slidably connected in the sliding hole.

[0005] Optionally, an anti-sway device is provided between the lifting trolley and the mounting frame. The anti-sway device includes two scissor arms arranged opposite each other. Both the top and bottom of the scissor arms are provided with connecting plates. The bottom connecting plate has a through hole in the center, through which a movable pulley passes.

[0006] Optionally, the mounting plate has a groove, the suction cup is slidably connected in the groove, a number of buffer springs are evenly arranged between the suction cup and the groove, limit blocks are provided on both sides of the groove, and limit plates matching the limit blocks are provided on both sides of the suction cup.

[0007] Optionally, a vision system is provided on both sides of the mounting plate.

[0008] The intelligent electromagnetic chuck crane of this invention has the following advantages:

[0009] (1) When the suction cup does not contact the object, the electromagnet will not be powered and there will be no air suction. When the suction cup contacts the object, the suction cup does not move and the connecting frame continues to descend. When the sliding plate touches the contact switch, the lifting device stops descending and the electromagnet is powered to attract the object. The sliding hole provides a buffer distance to prevent the wire rope from becoming loose.

[0010] (2) The anti-sway device can reduce the swing amplitude of the lifting equipment and improve the stability of the lifting process.

[0011] (3) The vision system can help determine whether the lifting device has been moved into place, thereby improving the accuracy of the lifting operation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1-6 As shown, an intelligent electromagnetic chuck 18 crane includes two end beams 1, with two main beams 2 positioned between them. A lifting trolley 3 is mounted on the main beams 2, and a drum mechanism 4 is mounted on the lifting trolley 3. A lifting device 5 is positioned below the lifting trolley 3. The lifting device 5 includes a mounting frame 6, with a movable pulley 7 mounted on the top of the mounting frame 6. An anti-sway device 8 is provided between the lifting trolley 3 and the mounting frame 6. The anti-sway device 8 includes two opposing scissor arms 9, with connecting plates 10 at both the top and bottom of the scissor arms 9. One end of the scissor arm 9 is hinged to the edge of the connecting plate 10, and the other end of the scissor arm 9 is slidably connected to the middle of the connecting plate 10. A through hole is provided in the center of the bottom connecting plate 10, through which the movable pulley 7 passes. The movable pulley 7 is connected to the drum mechanism 4 via a wire rope. When the drum mechanism 4 drives the movable pulley 7 to rise and fall, the scissor arms 9 can automatically adjust their opening and closing degree, reducing the swaying of the lifting device 5 and improving its stability.

[0020] The bottom of the mounting frame 6 is evenly provided with several connecting frames 11, and an electromagnetic chuck 18 is provided below the connecting frames 11. The connecting frames 11 have vertically arranged sliding holes 12, and the top of the sliding holes 12 is provided with a contact switch 13. The electromagnetic chuck 18 includes a mounting plate 14, and a sliding plate 15 is provided on the top of the mounting plate 14. The sliding plate 15 is slidably connected in the sliding hole 12. Vision systems are provided on both sides of the mounting plate 14. The vision systems use industrial cameras 16 to collect information and help the driver determine the position of the lifting device 5. The bottom of the mounting plate 14 has a sliding groove 17, and the suction cup 18 is slidably connected in the sliding groove 17. Several buffer springs 19 are evenly arranged between the top of the suction cup 18 and the sliding groove 17. Limit blocks 20 are provided on both sides of the sliding groove 17, and limit plates 21 that match the limit blocks 20 are provided on both sides of the suction cup 18.

[0021] When an object needs to be lifted, the operator moves the lifting device 5 above the object. With the help of the vision system, the operator determines the position of the lifting device 5 and then lowers it. When the suction cup 18 contacts the object, the suction cup 18 and the sliding plate 15 remain stationary, while the connecting frame 11 continues to descend. When the sliding plate 15 touches the contact switch 13, the lifting device 5 automatically stops descending. The electromagnet is energized to attract the object. The sliding hole 12 provides sufficient buffer distance to ensure that the suction cup 18 contacts the object while preventing the wire rope from slackening, thus improving the accuracy of the connection between the electromagnetic suction cup 18 and the object and ensuring the stability of the lifting operation. When the sliding plate 15 touches the contact switch 13 and the lifting device 5 does not stop automatically, the suction cup 18 can move upward within the sliding groove 17, providing the operator with some time for manual intervention and ensuring operational safety.

[0022] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
