The key components of the crane are made of high-temperature resistant alloy steel, which can maintain strength and stability in environments up to 1000°C. The structure and main components of the crane are usually made of high-temperature resistant steel to prevent deformation and damage in high-temperature environments. It is equipped with a motor with strong high-temperature adaptability and can operate normally under high-temperature conditions. Since the melting and casting processes of the copper melting furnace require lifting heavy objects, the crane needs to have a high load capacity and be able to safely lift and move the molten copper liquid.

[0023] The working principle and use process of the present invention: The high-temperature resistant crane specially used for copper melting furnace is a lifting equipment designed for high-temperature environment of copper melting, casting and smelting. This type of crane not only needs to have a strong lifting capacity, but also needs to be able to withstand high temperature and harsh working conditions. The key components of the crane are made of high-temperature resistant alloy steel, which can maintain strength and stability in an environment with a high temperature of up to 1000°C. The structure and main components of the crane are usually made of high-temperature resistant steel to prevent deformation and damage in a high-temperature environment. It is equipped with a motor with strong high-temperature adaptability and can work normally under high-temperature conditions. Since the melting and casting process of the copper melting furnace requires lifting heavy objects, the crane needs to have a higher load capacity and be able to safely lift and move molten copper. Existing cranes are Insufficient durability and stability in high temperature environments lead to wear and failure of components after long-term use. The mechanical arm of the crane cannot be freely extended and retracted, so the crane is not flexible enough to operate in a small space and complex working conditions. The crane cannot adapt to a variety of work scenarios. When the light in the copper melting furnace processing site is relatively dim, since the crane has a certain weight and a large size, nearby workers may be accidentally bumped and injured. After starting the micro motor 11, it will drive the threaded rod 8 connected to its output shaft to rotate synchronously, so that the adjustment block 10 threadedly sleeved with it moves left and right. Under the connection of the adjustment plate 12, the other adjustment block 10 will simultaneously move left and right at one end of the corresponding reinforcement rod 9. Through this structure, while the adjustment plate 12 moves To adjust the distance between the main arm 3 and the auxiliary arm 4, the use range of the crane can be increased, the problem that the crane is not flexible enough in a small space is solved, and it is suitable for a variety of work scenarios. The back of the fluorescent tape 26 is bonded to the surface of the prompt plate 25. The fluorescent tape 26 can emit fluorescence in a dim environment, which can remind nearby workers of the position of the crane and avoid injuries caused by accidental collision. As the auxiliary arm 4 moves left and right, since the mounting plate 13 and the auxiliary arm 4 are fixed to each other, the force is transmitted to the support block 16 through the mounting plate 13, and the support block 16 moves left and right at one end of the support rod 15. Through the movement of the two support blocks 16, the auxiliary arm 4 moves more smoothly, the triangle has stability, and the reinforcement plate 7 is arranged at the bottom of the telescopic frame 6, which The supporting force of the bottom of the telescopic frame 6 is enhanced. The high-temperature resistant layer 27 is made of refractory bricks, which can effectively isolate high temperatures, protect the crane and the surrounding environment from high-temperature damage, maintain the mechanical strength and stability of the material in a high-temperature environment, and avoid deformation and cracking. The sound-absorbing layer 28 is made of polyester fiberboard, which has excellent sound absorption and fire resistance. The sound insulation layer 29 is filled with polyurethane sound insulation board to isolate noise, effectively block the transmission of sound, and protect the environment and the quietness of the living space. The prompt plate 20 is fixedly set on one side of the fuselage 2, and the auxiliary shaft 22 can rotate between the two arc-shaped frames 21, which drives the auxiliary sleeve 23 fixed thereto to rotate, so that the inclination angle of the prompt plate 25 can be adjusted, which increases the use range of the fluorescent strip 26.To provide a more comprehensive reminder to the surrounding staff, after the hydraulic cylinder 18 is started, the piston rod 19 connected to its output shaft is driven to move up and down, and then the fuselage 2 is driven to move up and down.
