Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and in particular to a retractable ultra-long lead belt lifting weighing device and method. Background Art

[0002] The maximum rolling force of the ZR22B54 twenty-roller Sendzimir reversible cold rolling mill currently used by a certain company can reach 800t. The reversible rolling mode is used to roll the raw material coil with a thickness of 2.3mm into a cold hardened product with a thickness of 0.2-0.6mm. Considering the reduction of production costs, the raw material leader welding process is added before rolling, and the welding equipment of the preparation unit is used to complete the welding of the 3.0-6.0mm carbon steel leader with a length of 10-20 meters at the head and tail. The welded leader is used to replace the parent material during the rolling process to achieve the inner ring of the mandrel, reduce the length of the unrolled section of the parent material, and improve the yield rate of the rolled product. Before the annealing process of the cold hardened product, the head and tail leaders are cut off by special equipment at the entrance of the continuous annealing unit, and are collected and returned to the preparation unit for reuse. In the actual operation process, due to the long distance between the annealing entrance and the preparation unit and the crossing of the rolling mill equipment, a bridge crane is required for lifting, and the lifting capacity is 10-15 tons at a time. If the number of uses exceeds the process requirements, the guide belt needs to be scrapped and shipped and loaded uniformly. Each time it is lifted and loaded, the weight measurement must be completed simultaneously. The lifting device for ultra-long and thick plates is used frequently in daily production and delivery, which places high demands on the safety, practicality and convenience of the lifting device. Traditional lifting equipment cannot be adjusted in length, has no synchronous measurement function, and has poor lifting stability, which increases the workload of operators and is prone to various safety accidents.
