Description

Technical Field

[0001] This utility model relates to the field of lifting electromagnet technology, and in particular to the application of lifting electromagnets in steel plate cranes. Background Technology

[0002] With industrial development, steel plates, as important building materials and industrial raw materials, are facing increasing demands for handling and hoisting. In steel plate hoisting operations, lifting electromagnets have become one of the most widely used pieces of equipment due to their high efficiency and stable performance. Through electromagnetic adsorption technology, lifting electromagnets can quickly grasp and release steel plates, reducing manual operation, improving hoisting efficiency, and are widely used in steel processing, warehousing, and logistics.

[0003] Traditional steel plate lifting utilizes lifting electromagnets, which use the strong magnetic force generated by the electromagnet to attract and hold the steel plates, enabling lifting, handling, and stacking. This method is widely used in steel processing and logistics transportation, and is particularly suitable for the efficient handling of large quantities of steel plates. Lifting electromagnets can quickly grasp and release steel plates, greatly improving lifting efficiency while reducing the risks associated with manual operation. Although traditional lifting electromagnets have a relatively simple structure, their reliability and adaptability make them an important tool in industrial production and a classic solution for steel plate lifting.

[0004] However, traditional lifting electromagnets are often cumbersome to install and remove, and lack reliable limiting structures. This makes them prone to detachment due to vibration or impact during use, posing a safety hazard. Furthermore, their limited heat dissipation means that overheating during prolonged operation can impair performance and even damage the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a lifting electromagnet for steel plate cranes, aiming to improve the problem that the electromagnet is cumbersome to assemble and disassemble, and is prone to falling off due to vibration or collision.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A steel plate crane utilizes a lifting electromagnet, comprising an outer shell, a power supply fixedly connected to the top of the outer shell, an electromagnet slidably connected inside the outer shell, a limit plate fixedly connected to the bottom of the outer shell, a rotating ring rotatably connected inside the limit plate, a drive ring fixedly connected to the inner wall of the rotating ring, a limit component provided inside the drive ring for limiting the electromagnet, and a locking component provided inside the rotating ring for locking and fixing the rotating ring;

[0007] The limiting assembly includes a slide rod, the outer wall of which is slidably connected to the inside of the drive ring, and a limiting block is fixedly connected to the end of the slide rod, the limiting block being disposed below the electromagnet.

[0008] Furthermore, the locking assembly includes a locking block, the outer wall of which is slidably connected to the inside of the rotating ring, and a sliding shaft is fixedly connected to one side of the outer wall of the locking block, with a spring sleeved on the outer wall of the sliding shaft.

[0009] Furthermore, a pivot seat is fixedly connected to the upper surface of the outer shell, a chain is provided inside the pivot seat, a mounting seat is provided at one end of the chain, an air supply assembly is provided inside the outer shell, the air supply assembly is used to guide air into the interior of the outer shell, heat dissipation fins are fixedly connected to the inner wall of the outer shell, and a guide plate is fixedly connected to the inner wall of the heat dissipation fins.

[0010] Furthermore, the air supply assembly includes ventilation holes and a filter screen, the ventilation holes being opened inside the housing, and the filter screen being fixedly connected inside the housing.

[0011] Furthermore, the outer wall of the limiting block is slidably connected to the inside of the limiting plate, and the limiting block is used to limit the electromagnet.

[0012] Furthermore, the outer wall of the sliding shaft is slidably connected to the inside of the rotating ring, and the sliding shaft is used to guide the extension and retraction of the spring.

[0013] Furthermore, one end of the spring is fixedly connected to the inside of the rotating ring, and the other end of the spring is fixedly connected to the outer wall of the card block.

[0014] Furthermore, the upper and lower surfaces of the guide plate are both fixedly connected to the inner wall of the outer casing. The guide plate is used to concentrate and transport air, increase the air flow rate, and also increase the residence time of air inside the heat dissipation fins.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the rotating ring is first driven to rotate inside the limiting plate. Then, the driving ring and the sliding rod drive the limiting block to move, thereby limiting the electromagnet. This facilitates disassembly and assembly while preventing the electromagnet from falling off. In addition, the rotating ring can be locked after movement by the locking block, the sliding shaft and the spring, to prevent the limiting block from moving at will. This makes it easy to disassemble and assemble the electromagnet, and it can be quickly replaced according to different hoisting needs. It also prevents the electromagnet from falling off due to accidents, ensuring the safety of the operation. This solves the problem that the disassembly and assembly of electromagnets is relatively cumbersome and that they are prone to falling off due to vibration or collision.

[0017] 2. In this utility model, the outer casing is first conveniently installed and used through the rotating shaft seat, chain and mounting base. Then, clean air is sent to the inside of the outer casing through the ventilation holes and filter screen. Then, the air is cooled by heat dissipation fins and guide plates and sent to the outer wall of the electromagnet to achieve heat dissipation. This reduces the temperature rise of the electromagnet during long-term operation, thereby extending the service life of the equipment. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 4This utility model provides an embodiment of a steel plate crane using a lifting electromagnet, including an outer shell 1. A power supply 2 is fixedly connected to the top of the outer shell 1 to provide stable power support and ensure that the electromagnet 3 can generate sufficient magnetic force during operation. The electromagnet 3 is slidably connected inside the outer shell 1 and can move flexibly inside the outer shell 1 to adapt to different lifting needs and usage scenarios. A limit plate 4 is fixedly connected to the bottom of the outer shell 1. A rotating ring 5 is rotatably connected inside the limit plate 4. A drive ring 6 is fixedly connected to the inner wall of the rotating ring 5. Driving the rotating ring 5 to rotate inside the limit plate 4 can drive the drive ring 6 to rotate. A limit component is provided inside the drive ring 6 to limit the electromagnet 3. A locking component is provided inside the rotating ring 5 to lock and fix the rotating ring 5.

[0027] The limiting component includes a slide rod 7, the outer wall of which is slidably connected to the inside of the drive ring 6. The slide rod 7 can be moved by a pre-set arc-shaped groove inside the drive ring 6. A limiting block 8 is fixedly connected to the end of the slide rod 7. The limiting block 8 can limit the movement range of the electromagnet 3, thereby ensuring the safety and stability of the equipment during operation. The limiting block 8 is located below the electromagnet 3. The locking component includes a locking block 9, the outer wall of which is slidably connected to the inside of the rotating ring 5. The locking block 9 can quickly release the restriction on the rotating ring 5 when needed through its sliding connection. A sliding shaft 10 is fixedly connected to one side of the outer wall of the locking block 9. A spring 11 is sleeved on the outer wall of the sliding shaft 10. The spring 11 provides a rebound force, so that the locking block 9 can automatically reset after the operation is completed, further improving the ease of use of the equipment.

[0028] Reference Figure 1 and Figure 5A pivot seat 16 is fixedly connected to the upper surface of the outer casing 1. The pivot seat 16 provides reliable support for the installation of the chain 17 through its stable design. The chain 17 is arranged inside the pivot seat 16, and a mounting seat 18 is provided at one end of the chain 17. The mounting seat 18 is used to fix the chain 17 to the lifting equipment or other supporting equipment. An air supply assembly is arranged inside the outer casing 1 to guide air into the interior of the outer casing 1. A heat dissipation fin 14 is fixedly connected to the inner wall of the outer casing 1. The heat dissipation fin 14 significantly increases the heat dissipation surface area through its high thermal conductivity material and unique structural design, further improving the heat dissipation efficiency of the equipment. A guide plate 15 is fixedly connected to the inner wall of the heat dissipation fin 14. The guide plate 15, through its gaps, concentrates the air to the key heat dissipation area of ​​the electromagnet 3, and can also improve the air circulation inside the heat dissipation fin 14. The air supply component includes ventilation holes 12 and a filter 13. The ventilation holes 12 are opened inside the outer shell 1, and the filter 13 is fixedly connected inside the outer shell 1. The filter 13 effectively blocks impurities and dust in the air from entering the equipment through its high-efficiency filtration function. The outer wall of the limiting block 8 is slidably connected to the inside of the limiting plate 4. The limiting block 8 is used to limit the electromagnet 3. The outer wall of the sliding shaft 10 is slidably connected to the inside of the rotating ring 5. The sliding shaft 10 is used to guide the extension and retraction of the spring 11. One end of the spring 11 is fixedly connected to the inside of the rotating ring 5, and the other end of the spring 11 is fixedly connected to the outer wall of the locking block 9. The upper and lower surfaces of the guide plate 15 are both fixedly connected to the inner wall of the outer shell 1. The guide plate 15 is used to concentrate and transport air, increase the air flow rate, and also increase the residence time of air inside the heat dissipation fins 14.

[0029] Working principle: When using a steel plate crane with a lifting electromagnet, first press the locking block 9 to slide inside the rotating ring 5 and the limiting plate 4. At the same time, the spring 11 retracts. When the locking block 9 is completely inside the rotating ring 5, the restriction on the rotating ring 5 is released. Then, rotate the rotating ring 5 inside the limiting plate 4. This drives the drive ring 6 to rotate, which in turn causes the slide rod 7 to slide in the preset groove inside the drive ring 6. The movement of the slide rod 7 then drives the limiting block 8 to slide inside the limiting plate 4. When the limiting block 8 moves out of the limiting plate 4, the electromagnet 3 is limited. When the limiting block 8 moves to the designated position, it will drive the locking block 9 to move to the preset locking hole inside the limiting plate 4. At this time, the spring 11 will rebound and drive the locking block 9 back to the limiting plate 4, thus fixing the rotating ring 5 and the limiting block 8. This makes it easier to install and remove the electromagnet 3 and also prevents the electromagnet 3 from falling accidentally.

[0030] In addition, during use, air can be delivered to the interior of the outer casing 1 through the ventilation hole 12. During this process, the air is filtered by the filter screen 13, then cooled by the heat dissipation fins 14 inside the outer casing 1, and finally discharged to the outer wall of the electromagnet 3 through the gap in the middle of the guide plate 15 for heat dissipation. During this process, the limited gap in the middle of the guide plate 15 results in limited airflow, which allows more air to stay inside the heat dissipation fins 14 and increases the airflow velocity in the gap inside the guide plate 15, thereby improving the heat dissipation efficiency.

[0031] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
