The invention relates to the technical field of hoisting equipment, in particular to a lifting and winding system for a container portal crane sling and a working method. The winding system comprises a plurality of wheel rope assemblies, each wheel rope assembly comprises a lifting winding drum, a swinging pulley block and a steel wire rope, the steel wire rope bypasses the swinging pulley block, one end of the steel wire rope is wound on the lifting winding drum, and the other end of the steel wire rope is fixed; the swinging pulley blocks are divided into transverse pulley blocks and longitudinal pulley blocks, the lifting appliance is provided with short edges and long edges, the transverse pulley blocks are arranged on the short edges on the two sides of the lifting appliance, swinging shafts of the transverse pulley blocks are perpendicular to the short edges, the transverse pulley blocks on the short edges on the two sides are arranged in pairs, and steel wire ropes wound on the transverse pulley blocks form an inverted triangle; the longitudinal pulley blocks are arranged on the long sides of the two sides of the lifting appliance, swing shafts of the longitudinal pulley blocks are perpendicular to the long sides, the longitudinal pulley blocks on the long sides of the two sides are arranged in pairs, and steel wire ropes wound on the longitudinal pulley blocks form an inverted triangle. By means of the system, the operation efficiency is improved, and the operation comfort of the cab is improved.

    本发明涉及起重设备技术领域,尤其涉及一种集装箱门式起重机吊具起升缠绕系统及工作方法。缠绕系统包括多组轮绳组件,每组轮绳组件包括起升卷筒、摆动滑轮组和钢丝绳,所述钢丝绳绕过摆动滑轮组,一端绕制在升降起升卷筒上另一端固定;所述摆动滑轮组分为横向滑轮组和纵向滑轮组,所述吊具具有短边和长边,横向滑轮组设置在吊具两侧的短边且其摆动轴垂直于短边,每侧短边的横向滑轮组成对布置,且其上绕制的钢丝绳形成倒三角形;所述纵向滑轮组设置在吊具两侧的长边且其摆动轴垂直于长边,每侧长边的纵向滑轮组成对布置,且其上绕制的钢丝绳形成倒三角形。通过本系统提高了作业效率,提升了司机室操作舒适性。
