The invention relates to the technical field of lifting appliances, in particular to a flexible lifting appliance capable of being manually or automatically adjusted. The flexible lifting appliance comprises a lifting arm upper frame, wherein a plurality of lifting appliance fixing mechanisms and a plurality of lifting appliance balancing devices are arranged at the upper end of the lifting arm upper frame; front lifting arms and rear lifting arms are symmetrically arranged on the left side and the right side of the lifting arm upper frame; supporting pivots are arranged at the lower ends of the front lifting arms and the rear lifting arms which are fixedly connected through lifting arm connecting beams; rear lifting arm adjusting devices are arranged at the upper ends of the rear lifting arms on the left and right sides and are used for adjusting the front-back distance of the rear lifting arms so as to adapt to lifting and carrying of different types of products; and the four groups of lifting appliance balancing devices are respectively arranged on the lifting arm upper frame in a bilateral symmetry manner. The front-back distance of the rear lifting arms is adjusted through the rear lifting arm adjusting devices, so that stroke positioning of the rear lifting arms is changed, and the diversified positioning and transferring requirements of multiple workpiece vehicle types are met. The lifting arm adjusting devices can carry out manual adjustment or PLC control through a power device, and adjustment is easy and convenient.
本发明及一种吊具技术领域,具体涉及一种人工或自动调整的柔性吊具。包括吊臂上框架,吊臂上框架上端设置有若干吊具固定机构和若干吊具平衡装置,吊臂上框架左右侧边对称设置有前吊臂和后吊臂,前吊臂和后吊臂下端均设置有支撑支点,前吊臂和后吊臂通过吊臂连接梁固定连接,左右侧边的后吊臂上端设置有后吊臂调节装置。后吊臂调节装置用于调节后吊臂的前后距离以适应不同型号的产品吊取搬运。吊具平衡装置设置有四组、分别左右对称设置在吊臂上框架上。本发明通过后吊臂调节装置调节后吊臂的前后距离,使后吊臂改变行程定位,满足多钟工件车型的多样性定位转载需求。吊臂调节装置可通过人工手动调整,或者通过动力装置进行PLC控制,调节简单方便。
