Description

Technical Field

[0002] Carbon-carbon composite material is a high-performance material made of carbon fiber and carbon-based resin by high-temperature carbonization. It has the advantages of high strength, high modulus, high heat resistance, high wear resistance, and high corrosion resistance. It is widely used in aerospace, nuclear energy, chemical industry, metallurgy and other fields. Common forms of carbon-carbon composite materials include plates, rods, tubes, etc. Among them, carbon-carbon cylinder is an important structural part that can be used to make reactors, heat exchangers, catalyst carriers and other equipment.

[0003] The manufacturing process of carbon-carbon cylinder generally includes steps such as carbon fiber preforming, resin impregnation, hot pressing curing, carbonization, re-impregnation, and re-carbonization. After multiple cycles, a high-density, high-strength, and high-heat-resistant carbon-carbon cylinder is formed. The size and weight of the carbon-carbon cylinder vary according to different uses and requirements. Generally, the diameter is 1 meter to 10 meters, the length is 5 meters to 50 meters, and the weight is between 1 ton and 100 tons. The carbon-carbon cylinder needs to be transferred during production, and then it needs to be hoisted. Hoisting refers to the process of transporting the carbon-carbon cylinder from the production site to the installation site and installing it to the predetermined position. The hoisting of the carbon-carbon cylinder is a project with high technical difficulty and high risk. It is necessary to consider many factors such as the characteristics of the carbon-carbon cylinder itself, the performance of the hoisting equipment, the conditions of the hoisting site, and the safety of the hoisting process. The traditional hoisting method is to use equipment such as cranes or cranes to lift the carbon-carbon cylinder from the horizontal direction through hooks, slings, lifting ears and other hoists, and then rotate it to the vertical direction, and then hoist it to the predetermined position. The advantages of this method are simple equipment and easy operation, but the disadvantage is that the carbon-carbon cylinder is unevenly stressed during the lifting process, which is prone to deformation, damage or falling off, especially for large, heavy and thin-walled carbon-carbon cylinders. Therefore, it is necessary to develop a large carbon-carbon cylinder lifting tool to solve the above technical problems. Utility Model Content
