Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to an automated crystallizer copper tube hoisting equipment. Background Art

[0002] The copper tube of the crystallizer is the core component of the continuous casting machine. It is used to receive molten steel. The molten steel is rapidly cooled in the copper tube of the crystallizer to form a solidified shell on the outside and unsolidified molten steel on the inside. Its structure, material and performance parameters play a decisive role in the quality of the ingot and the production capacity of the continuous casting machine. The copper tube of the crystallizer is large in size and heavy in weight. If it is transported manually, it will not only be labor-intensive, but also have high safety risks.

[0003] At present, in order to be able to transport the crystallizer copper tube, in actual production, a crane is generally used to lift the copper tube for transportation. When lifting, the copper tube needs to be fixed by an external clip first, and then connected to the clip through the lifting equipment, and then the copper tube is integrated to ensure that the copper tube is stable and does not fall during transportation.

[0004] In the related technology, since most of the current lifting equipment uses electric hoists in combination with special lifting equipment, this method improves work efficiency and reduces manpower requirements, but it still lacks in precision control, especially in rapid positioning and fine adjustment. In addition, this method cannot effectively solve the durability and reliability problems of working in high temperature environments. At the same time, during the lifting process, it is still necessary to manually dock and lock the lifting equipment with the clips on the copper pipe. The operation is relatively cumbersome and lacks intelligent design, which makes it difficult to adapt to the future trend of intelligent manufacturing. Summary of the invention

[0005] In order to solve the problem that the current copper tube lifting equipment needs to manually connect and lock the lifting device with the clips on the outside of the copper tube when lifting the copper tube, and cannot quickly position and fine-tune, and cannot effectively solve the durability and reliability issues working in high temperature environments, the present application provides an automated crystallizer copper tube lifting equipment.
