Specific workflow: Bridge-type metallurgical lifting equipment enables the hook to move to a designated position in three-dimensional space through the coordinated action of the trolley running mechanism and the trolley running mechanism; When a heavy object needs to be lifted, the operator starts the lifting component 3 through the electrical control system, the motor drives the drum to rotate, the wire rope is wound around the drum, the hook component 4 rises, and the heavy object is lifted; Then, the heavy object is transported to the required location through the operation of the trolley and the small car, and then the heavy object is lowered by the lifting component 3; During the whole process, the electrical control system will accurately control each mechanism according to the operator's instructions and the operating status of the equipment to ensure the safety and efficiency of the lifting operation; By starting the lifting component 3, the motor drives the drum to rotate, and the wire rope is wound around the drum, so that the wire drives the hook mechanism 42 to move upward through the pulley mechanism 41, so that the hook ring 422 is gradually stressed, and the heavy object is lifted steadily; When lifting the cargo, the auxiliary steel rope for lifting the cargo is passed through the opening of the hook ring 422 and enters the hook ring 422, and the sliding resistance component 425 is moved in the placement groove 427, so that the resistance component 425 can be against the opening of the hook ring 422, and the position of the resistance component 425 is limited and fixed by the sliding component 426, so that the resistance component 425 closes the opening of the hook ring 422 to prevent the auxiliary steel rope from falling out, and at the same time, a placement plate 424 is provided on the inner side of the hook ring 422, and a plurality of placement grooves 427 are opened on the placement plate 424, and the material of the placement plate 424 is rubber material, so that the auxiliary steel rope for lifting the cargo is placed in the hook ring 422, and the contact friction between the auxiliary steel rope and the placement plate 424 can be increased, thereby ensuring the stability of the material during the lifting process;

At the same time, by pushing the circular plate 4266, the circular plate 4266 drives the connecting shaft 4253 through the slider 4265 to move in the moving groove 423, so that the connecting shaft 4253 drives the blocking rod 4251 to be against the opening of the hook ring 422. At the same time, the position of the blocking rod 4251 is limited and fixed by adjusting the limiting kit 4267. When the connecting shaft 4253 drives the blocking rod 4251 to abut against the opening of the hook ring 422, the limiting block 42671 is rotated so that the limiting block 42671 drives the threaded rod 42672 to move on the inner threads of the circular plate 4266 and the slider 4265, so that the threaded rod 42672 abuts against the sliding rod 4264, thereby fixing the position of the slider 4265, thereby preventing the blocking rod 4251 from being deviated at the opening of the hook ring 422. The rotation of the limit block 42671 drives the threaded rod 42672 to move in a threaded manner, so as to achieve precise adjustment and locking of the position of the slider 4265. The operator can accurately determine the degree of tightness between the threaded rod 42672 and the slide bar 4264 by precisely controlling the rotation angle of the limit block 42671 according to actual needs, thereby fixing the slider 4265 at the required precise position, ensuring the matching accuracy of the stop rod 4251 and the opening of the hook ring 422, and meeting the requirements of different lifting operations for position accuracy; After the position of the resisting rod 4251 and the opening of the hook ring 422 are limited and fixed, the resisting rod 4251 can be pushed at the same time, so that the resisting rod 4251 drives the squeezing block 42555 to move on the squeezing rod 42553, and the squeezing block 42555 squeezes the connecting spring 42556, so that the resisting rod 4251 can move to the inside of the hook ring 422, thereby facilitating the taking of the auxiliary steel cable; During the hoisting operation, if it is found that the position of the auxiliary steel cable needs to be temporarily adjusted, or the situation inside the hook ring 422 needs to be checked, the operation can be conveniently performed by pushing the blocking rod 4251 without completely releasing the limit fixation, which ensures the continuity and safety of the hoisting operation to a certain extent and avoids the potential safety hazards caused by frequent disassembly and fixation; After the cargo is hoisted to a suitable position, when disassembly work is required, the limiting kit 4267 can be rotated so that the limiting kit 4267 releases the limit between the slider 4265 and the slide rod 4264, so that the circular plate 4266 is pushed, and the circular plate 4266 drives the connecting shaft 4253 to move in the moving groove 423 through the slider 4265, until the side of the slider 4265 is against the inner side of the magnetic block 4263, so that the position of the slider 4265 is magnetically fixed, and at the same time, the blocking rod 4251 is separated from the opening of the hook ring 422, so that when the auxiliary steel cable on the hook ring 422 is unloaded, the blocking rod 4251 is prevented from interfering with the normal unloading work; When the side of the slider 4265 abuts against the inner side of the magnetic block 4263, the slider 4265 is fixed by magnetic force, which can achieve accurate positioning of the slider 4265, ensure that the blocking rod 4251 is accurately separated from the opening of the hook ring 422, and avoid unloading difficulties or other problems caused by inaccurate positioning; The magnetic fixation ensures to a certain extent that the slider 4265 will not move randomly during the unloading process, and maintains the blocking rod 4251 in a state of being separated from the opening of the hook ring 422, which provides a stable condition for the unloading work and reduces the possibility of interference with the unloading due to the accidental resetting of the blocking rod 4251; This design of adjusting the position of the resistance rod 4251 by rotating, pushing and other operations allows the equipment to maintain good adaptability in different unloading scenarios and cargo types. Whether it is the lifting and disassembly of small or large cargo, it can be completed through corresponding operations, which improves the versatility of the equipment.
