Description

TECHNICAL FIELD

[0002] In the modern steel production process, the double-line finished product cross electromagnetic crane system plays a crucial role, it is responsible for efficient, safe finished steel from production line to the storage area or subsequent processing link. With the progress of technology and the change of production demand, the system is constantly optimized and upgraded, among them, the hanging beam gradually changes from the traditional configuration to 3 magnetic disk configuration to adapt to more extensive production needs, especially in the production of 6 meters round steel and other longer specifications, by flexible selection and use of 2 magnetic disks on the finished product collection table operation, not only improves the operation efficiency, but also enhances the flexibility of operation. However, this improvement has exposed several technical problems that need to be solved in the actual application process, these problems not only concern the production efficiency, but also directly relate to the safety of operation and the convenience of equipment maintenance.

[0003] Problem one: the safety hazard caused by the misabsorption of magnetic disk transmission chain

[0004] In the double-line finished product cross electromagnetic crane system, when the hanging beam is configured with 3 magnetic disks but only 2 of them are used for operation, the third magnetic disk that is not in use becomes a potential risk source. Especially when the magnetic disk is lowered to a lower position to cooperate with the operation of the finished product collection table, if the control is improper, the unused magnetic disk may be accidentally absorbed onto the transmission chain on the collection table. This misabsorption phenomenon not only causes abnormal stress on the chain, causing derailment, jamming and other mechanical failures, and in severe cases may even cause the chain to break, directly threatening the normal operation of the collection table and the continuity of the entire production line. In addition, such failures often require a long downtime for repair, greatly affecting production efficiency and cost control.

[0005] Problem two: magnetic disk protection and safety problems in the maintenance process of hanging beam

[0006] In the daily maintenance and management of steel production enterprises, large-scale maintenance of double-line finished product cross electromagnetic crane system, main volume equipment maintenance or replacement of steel wire rope and other operations are inevitable. These maintenance operations usually require the hanging beam to be removed from the electromagnetic crane. However, due to the lack of a specially designed support structure, the removed hanging beam can only be placed directly on the magnetic disk, which not only puts a lot of pressure on the surface of the magnetic disk, easily causing damage to the surface of the magnetic disk, affecting its magnetic performance and service life, but also brings great inconvenience to the subsequent magnetic disk chain and magnetic disk line replacement work. More seriously, this improper placement method may also cause safety accidents, such as hanging beam sliding, magnetic disk damage and splashing, which poses a serious threat to the safety of operating personnel.

[0007] Therefore, an innovative technical solution is urgently needed to solve these problems to ensure efficient and safe production, reduce maintenance costs, and improve the reliability and stability of the entire system. Practical new type content

[0018] In order to make the purpose, technical scheme and advantages of the present application more clear and understandable, the present application will be further described in detail below in conjunction with embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0019] Please refer to Figures 1 to 2 A magnetic disc protection bottom support device for electromagnetic crown block based on three magnetic discs, comprising a crown block hanging beam 1, the lower end of the crown block hanging beam is connected with three magnetic discs 2; two bottom supports that rise and fall with the crown block hanging beam are evenly installed between the adjacent magnetic discs at the lower end of the crown block hanging beam; this design directly introduces a physical barrier, i.e. a bottom support, between adjacent magnetic discs. When the magnetic disc is lowered to a lower position, the bottom support can effectively prevent the unused magnetic disc from directly contacting the transmission chain on the finished product collection table, thereby avoiding the occurrence of the misabsorption phenomenon. This not only significantly reduces the risk of derailment, jamming or breakage of the transmission chain, but also ensures the normal operation of the collection table and the continuity of production, greatly improving the safety and efficiency of the operation. The connection design of the bottom support and the crown block hanging beam ensures their synchronous movement during operation. No matter how high the hanging beam rises, the bottom support can keep the relative position unchanged and continuously provide protection. This design not only simplifies the operation, but also enhances the stability and reliability of the system. The upper part of the bottom support is fixedly connected with the crown block hanging beam, and the lower surface of the bottom support is located on the same horizontal plane. By ensuring the horizontal consistency of the lower surface of the bottom support, the present application not only ensures the normal operation of the magnetic disc, but also provides a stable support platform for the hanging beam during maintenance. When the hanging beam needs to be removed for maintenance or replacement, the bottom support can evenly distribute the weight of the hanging beam, avoiding direct pressure on the magnetic disc, effectively protecting the surface integrity and magnetic performance of the magnetic disc, and prolonging the service life of the magnetic disc.

[0020] Further preferably, the base support includes vertical brackets 3-1 and horizontal brackets 3-2, and the lower end of the vertical bracket is welded vertically on the horizontal bracket middle stand 3-20. The cross-sectional shape of the vertical bracket and the horizontal bracket is both a structural steel; using structural steel as the main material of the base support, using its high strength and good anti-deformation ability to provide sufficient carrying capacity and stability for the base support. The combination design of the vertical bracket and the horizontal bracket not only enhances the structural strength of the base support, but also facilitates installation and maintenance, and reduces manufacturing cost.

[0021] Further preferably, the two plates 3-21 of the horizontal bracket are parallel to the vertical bracket middle stand 3-10, and this welding method ensures the firm connection between the vertical bracket and the horizontal bracket, improves the overall rigidity and stability of the base support. During operation, even if facing larger load or vibration, the base support can maintain structural integrity, effectively support the beam, and ensure operation safety.

[0022] Further preferably, the upper end of the bracket is welded on the crane beam. This connection method not only improves the stability of the base support device, but also ensures its firmness during long-term operation, effectively preventing loosening or falling off due to vibration or load changes. The welding connection simplifies the installation process, reduces maintenance requirements, and improves the reliability and durability of the entire electromagnetic crane system.

[0023] In addition to the welding structure, a connecting plate is welded on the upper end of the bracket, and the connecting plate is fixedly connected to the lower web plate of the crane beam through fasteners. This design facilitates the disassembly and replacement of the base support device. When maintenance or repair is needed, the fasteners can be easily removed, and the base support device can be separated from the beam, improving the convenience and efficiency of maintenance. At the same time, the design of the connecting plate also enhances the connection strength between the base support and the beam, ensuring safety during operation.
