The integrated large-tonnage hydraulic lifting device comprises a first-stage cylinder barrel with an opening in the upper end, a bracket extending outwards is arranged on the lower half portion of the first-stage cylinder barrel, a second-stage cylinder barrel is arranged in the first-stage cylinder barrel, a piston rod is arranged in the second-stage cylinder barrel, an energy accumulator is fixed to the bracket, and the energy accumulator comprises a shell. An inner cavity of the shell is divided into an upper air cavity and a lower oil cavity through a first piston, a two-way pump is integrated in the bracket, an upper oil opening of the two-way pump is communicated with a lower oil cavity of the energy accumulator, and a lower oil opening of the two-way pump is communicated with a positive cavity of the first-stage cylinder barrel and a positive cavity of the second-stage cylinder barrel. The integrated large-tonnage hydraulic lifting device is compact in structure, multi-stage cylinder oil runs in a closed mode, the energy storage function and the lifting function are integrated, the output power of the integrated large-tonnage hydraulic lifting device is large, energy consumption can be effectively reduced, and rapid lifting of large-tonnage objects is achieved.
本发明涉及一种集成式大吨位液压举升装置,包括上端开口的一级缸筒,一级缸筒的下半部设有向外延伸的托座,一级缸筒中设有二级缸筒,所述二级缸筒中设有活塞杆,托座上固定有蓄能器,蓄能器包括壳体,壳体的内腔通过第一活塞分隔为上气腔和下油腔,托座中集成有双向泵,双向泵的上油口与蓄能器的下油腔连通,双向泵的下油口与一级缸筒和二级缸筒的正腔连通。本集成式大吨位液压举升装置结构紧凑,多级缸油液闭式运行,将蓄能与举升功能一体化,其输出功率大,可以有效降低能耗,实现大吨位物体的快速举升。
