[0002] Ton bags are used to transport bulk powdery materials and are characterized by their large capacity, light weight, and ease of loading and unloading, making them a common type of packaging container. Current methods of handling ton bags mainly rely on manual hooking, mechanical handling, and manual unhooking. This is not only complex and labor-intensive but also inefficient. In some special locations, it may also pose risks such as radiation exposure, and manual operation presents significant safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide an automated ton bag lifting device that can adsorb, grab, and lift the ton bag lifting strap. It has a high degree of automation and can improve production efficiency and safety.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automated ton bag lifting device, comprising a lifting device frame, with rotating mechanisms fixedly connected to both ends of the bottom of the lifting device frame, a hook mounted on the rotating mechanism, and an electro-permanent magnet chuck provided on the side of the hook; the rotating mechanism includes a fixed frame, with a rotating shaft rotatably connected to the fixed frame, the hook fixedly connected to the rotating shaft, one end of the rotating shaft passing through the fixed frame and fixedly connected to a gear; a drive mechanism matching the gear is provided at the bottom of the lifting device frame, the drive mechanism including an electric push rod and a rack, the electric push rod being fixedly connected to the bottom of the lifting device frame, the rack being fixedly connected to the end of the electric push rod, and the rack meshing with the gear.

[0005] Optionally, a limit switch is provided at the top of the lifting frame, and a limit mechanism is provided on the fixed frame. The limit mechanism includes a slide rod, and a vertically arranged slide groove is provided on the fixed frame. The slide rod is slidably connected in the slide groove. The upper part of the slide rod passes through the fixed frame and is equipped with an upper limit plate. The top of the slide rod passes through the lifting frame and cooperates with the limit switch. The bottom of the slide rod passes through the fixed frame and is equipped with a lower limit plate. An electro-permanent magnet chuck is fixedly connected to the bottom of the lower limit plate. A limit block is fixedly connected to the slide rod, and a spring is installed between the top of the slide groove and the limit block. The spring is sleeved on the slide rod.

[0006] Optionally, each fixed frame is equipped with four sliding rods arranged in a rectangular structure. The bottom of two sliding rods on the same side is connected to a lower limit plate through a universal ball joint. The two lower limit plates are located on both sides of the hook, and an electro-permanent magnet chuck is fixedly connected to the bottom of each of the two lower limit plates.

[0007] Optionally, guard plates are provided on both sides of the rotating mechanism, and the guard plates are fixedly connected to the bottom of the lifting frame.

[0008] Optionally, a lifting ring is fixedly connected to the middle position of the top of the lifting frame.

[0009] The automated ton bag lifting device of this utility model has the following advantages: (1) Open the hook and align the electro-permanent magnet chuck with the iron block of the ton bag. Then, operate the lifting device to descend to the position of the ton bag. After the electro-permanent magnet chuck is magnetized and attracts the iron block of the lifting belt, the lifting device rises to a certain height and stops. At this time, the lifting belt is lifted. Then, use the drive mechanism to rotate the hook inward so that the hook hooks the lifting belt. After the lifting belt is hooked, the lifting device continues to rise to lift the ton bag. The lifting belt can be automatically attracted, grabbed and lifted without human intervention, which improves the efficiency and safety of ton bag lifting.

[0010] (2) The limit mechanism can stop the movement of the spreader in time when the spreader is lowered to the position, and assist the driver in judging the position of the spreader.

[0011] (3) Both sides of the hook are equipped with electro-permanent magnet chucks, which can improve the accuracy of adsorbing the lifting sling and facilitate the hook to grab the lifting sling. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1-3As shown, this application is used for lifting ton bags with double lifting straps. The area where the lifting straps are attracted includes a metal plate with a thickness of not less than 4mm (capable of being attracted by a magnet). Iron or steel plates are acceptable, and the thickness of the outer layer of the metal plate is not greater than 1mm. An automated ton bag lifting device includes a lifting frame 1. A lifting ring 2 is fixedly connected to the middle position of the top of the lifting frame 1 to facilitate connection between the lifting device and a crane. Rotating mechanisms are fixedly connected to the left and right ends of the bottom of the lifting frame 1. The rotating mechanism includes a fixed frame 3. A U-shaped groove is formed in the middle of the fixed frame 3. A rotating shaft 4 is horizontally rotatably connected to the fixed frame 3 via an angular contact ball bearing. A hook 5 is fixedly connected to the rotating shaft 4 and disposed within the U-shaped groove. One end of the rotating shaft 4 passes through the side wall of the fixed frame 3 and is fixedly connected to a gear 6. The bottom of the lifting frame 1 is equipped with a drive mechanism that matches the gear 6. The drive mechanism includes an electric push rod 7 and a rack 8. The electric push rod 7 is fixedly connected to the bottom of the lifting frame 1, and the rack 8 is fixedly connected to the end of the electric push rod 7. The rack 8 meshes with the gear 6. The electric push rod 7 drives the rack 8 to translate, thereby driving the gear 6 and the rotating shaft 4 to rotate, so that the hook 5 can rotate in the U-shaped groove. The two hooks 5 are symmetrically arranged and synchronously retract inward or open outward.

[0017] A limit switch 9 is installed on the top of the lifting frame 1, and a limit mechanism is installed on the fixed frame 3. The limit mechanism includes four sliding rods 10. The fixed frame 3 has four vertically arranged sliding grooves, which are arranged in a rectangular structure. The sliding rods 10 are slidably connected in the sliding grooves. The upper part of the sliding rod 10 passes through the top of the fixed frame 3 and is equipped with an upper limit plate 11. The top of the sliding rod 10 passes through the lifting frame 1 and cooperates with the limit switch 9. The bottom of the sliding rod 10 passes through the bottom of the fixed frame 3. The bottom of the two front sliding rods 10 is connected to a lower limit plate 12 through a universal ball joint. The bottom of the two rear sliding rods 10 is also connected to a lower limit plate 12 through a universal ball joint. The bottom of both plates is fixedly connected to an electro-permanent magnet chuck 13. The two electro-permanent magnet chucks 13 are located on the front and rear sides of the hook 5, respectively. The maximum tilt angle of the lower limit plate 12 is 15°, which can increase the adaptability of the electro-permanent magnet chuck 13. The lower part of the slide bar 10 is fixedly connected to the limiting block 14. A spring 15 is installed between the top of the slide groove and the limiting block 14. The spring 15 is sleeved on the slide bar 10. Under the action of the spring 15, the upper limiting plate 11 is in contact with the top of the fixing frame 3, and the lower limiting plate 12 is spaced apart from the bottom of the fixing frame 3.

[0018] The front and rear sides of the rotating mechanism are provided with guard plates 16, which are fixedly connected to the bottom of the lifting frame 1. The guard plates 16 can protect the rotating mechanism and the drive mechanism. The front side of the guard plate 16 is fixedly connected to the control box 17, and a communication device 18 is installed on one side of the control box 17 for sending and receiving signals. The rear side of the guard plate 16 is equipped with a lithium battery to power the lifting device.

[0019] The operator remotely maneuvers the crane to a position directly above the ton bag, lowering the lifting device. During descent, hook 5 opens. After descending a certain height, the lifting device is adjusted to align the electro-permanent magnet chuck 13 with the metal plate of the ton bag. The lifting device continues to descend. When the electro-permanent magnet chuck 13 reaches the ton bag, the bag pushes the sliding rod 10 upwards, causing it to contact the limit switch 9, signaling the crane to stop. The electro-permanent magnet chuck 13 then magnetizes, attracting the metal plate. Two electro-permanent magnet chucks 13 have a higher probability of attracting the metal plate. After attraction, the lifting device rises to a certain height and stops, fully opening the ton bag's lifting strap. Hook 5 is then rotated inwards to hook the lifting strap, and the lifting device rises again to lift the ton bag. Once lifted to the designated position, the lifting device is lowered until the lifting strap is no longer under load. The lifting device stops descending, and hook 5 is then rotated outwards to disengage from the lifting strap, completing one lifting cycle.

[0020] 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.
