Description

TECHNICAL FIELD

[0001] The utility model belongs to metallurgy field, specifically disclose a horizontal rotation special mechanism for new energy ladle transport trolley. BACKGROUND

[0002] In the steel industry, the process of transporting ladle in steelmaking plant is a crucial link. The existing technology is usually to hoist the ladle to the transport trolley by the crown block, which is equipped with argon blowing device for soft stirring of the molten steel. Then, the transport trolley moves on the horizontal or vertical track until it reaches the continuous casting workshop span, and the ladle is hoisted to the continuous casting ladle rotary table by the crown block. In this process, the transport trolley plays a key role in carrying and transporting the ladle.

[0003] However, the existing technology has significant technical bottlenecks and deficiencies. First of all, since the ladle transport trolley can only move linearly on the horizontal or vertical track, when a 90-degree turn is needed, it must rely on the hoisting of the crown block to complete. This not only causes the lag of production rhythm, but also increases the unsafe production factors. During each hoisting process, the center of gravity of the ladle may affect the stable operation of the transport trolley, thereby causing safety hazards.

[0004] Secondly, in the smelting production process, the existing transport trolley is mostly powered by external power supply, using cable reel or cable drag chain to deliver electric energy. This way not only causes excessive load and increases motor torque, which is not conducive to energy saving and emission reduction, but also requires higher motor capacity. In addition, the dragging and winding of the cable may also cause mechanical failure, further affecting production efficiency and safety.

[0005] Furthermore, the traditional ladle transport trolley mostly uses manual operation to solve the existing problems. This operation mode not only has high labor intensity and low work efficiency, but also has high risk of safety accidents, seriously affecting the safety and efficiency of smelting production.

[0006] In summary, the existing technology has many technical bottlenecks and deficiencies in the process of transporting ladle, including the limitations of the movement of the transport trolley, the inconvenience of external power supply, and the high risk of manual operation. These problems need to be solved to improve the production efficiency and safety of the steelmaking plant and realize more green, energy-saving and efficient smelting production. SUMMARY

[0007] The utility model discloses a horizontal rotation special mechanism for new energy ladle transport trolley, which realizes 90-degree horizontal rotation of the new energy transport trolley through the horizontal rotation chassis car, without relying on the hoisting of the crown block, solving the limitation that the traditional transport trolley can only move on the straight track.

[0008] The specific technical solution of this utility model is as follows:

[0009] A dedicated horizontal rotation mechanism for a new energy steel ladle transport trolley includes:

[0010] The new energy transport trolley carries a steel ladle and is equipped with a new energy storage battery as its power source;

[0011] A horizontally rotating chassis vehicle that carries a new energy transport trolley and enables it to rotate horizontally.

[0012] The electric motor of the rotating chassis is connected to the reducer of the rotating chassis via a drive shaft, and the reducer then drives the gears of the rotating chassis to rotate.

[0013] The gear meshes with the gear ring below the new energy transport trolley to achieve horizontal rotation of the new energy transport trolley.

[0014] The argon-blowing cable chain for molten steel ladles is connected at one end to a new energy transport trolley and at the other end to an argon supply system, and is used to gently stir the molten steel during transportation.

[0015] The new energy transport trolley is connected to the top platform of the horizontal rotating chassis through its wheels to ensure rotational stability; the new energy transport trolley and the argon blowing cable of the molten steel ladle are detachably connected to adapt to different operational needs.

[0016] The steel delivery waiting station for transport trolleys is used for new energy transport trolleys to wait to receive molten steel.

[0017] The rotating station for transport trolleys is used for horizontal rotation of new energy transport trolleys.

[0018] The transport trolley charging station is equipped with a transport trolley charging pile for charging the batteries of the new energy transport trolley.

[0019] The ladle hoisting station of the transport trolley is used to hoist the molten steel ladle on the new energy transport trolley to the continuous casting bay by means of an overhead crane;

[0020] The transport trolley maintenance station provides the necessary equipment and space for the maintenance of new energy transport trolleys.

[0021] The connection between the new energy transport trolley and the horizontal rotating chassis is such that the wheels are in direct contact with the platform, ensuring stability and smoothness during rotation.

[0022] The motor is controlled by frequency conversion transmission to achieve precise adjustment of rotation speed and positioning, so as to meet the rotation requirements under different working conditions.

[0023] The argon blowing drag chain of the ladle has certain flexibility to adapt to the position change of the new energy transport trolley in the rotating process, and ensures the continuity and stability of the argon supply.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] Firstly, by introducing the horizontal rotating chassis car, the 90-degree horizontal rotation of the new energy transport trolley is realized, and the limitation that the traditional transport trolley can only move on the straight track is completely eliminated. This improvement avoids the frequent use of the overhead crane, reduces the lag of the production rhythm, and eliminates the unsafe production factors that may be caused in the hoisting process, thereby significantly improving the production efficiency and safety.

[0026] Secondly, the new energy transport trolley is powered by new energy storage batteries, replacing the traditional external power supply. This not only reduces the load and the motor torque, but also is beneficial to energy saving and emission reduction, reduces the requirement for motor capacity, thereby prolongs the service life of the equipment and reduces the maintenance cost. In addition, the introduction of the new energy storage battery also makes the transport trolley more flexible and not limited by external power supply, thereby improving the adaptability and reliability of the equipment.

[0027] Furthermore, the utility model patent realizes remote operation, reduces manual intervention, reduces the labor intensity of workers, and improves work efficiency. At the same time, remote operation also reduces the risk of direct contact of personnel with high-temperature ladles, further improves the safety of production. In addition, the design of the mechanism also considers the convenience of maintenance, so that the daily maintenance and repair of the equipment are more simple and fast.

[0028] To sum up, the horizontal rotating special mechanism for the new energy ladle transport trolley provided by the utility model patent solves a plurality of shortcomings in the prior art through a series of technical innovations and improvements, significantly improves the production efficiency and safety of the steel mill, reduces the operating cost, and provides strong support for the green development of the steel industry.
