The invention discloses a large lifting platform. The large lifting platform comprises a lifting platform board, a liquid charging fuel tank assembly, a main oil cylinder for jacking up the lifting platform board and a plurality of auxiliary oil cylinders for supporting the lifting platform board, wherein the main oil cylinder is connected to the central position of the bottom of the lifting platform board, the auxiliary oil cylinders are connected to the peripheral positions of the bottom of the lifting platform board, the main oil cylinder communicates with the liquid charging fuel tank assembly, a main oil cylinder hydraulic control one-way valve communicating with the liquid charging fuel tank assembly is arranged at the bottom of the main oil cylinder, each auxiliary oil cylinder is equipped with an auxiliary oil cylinder oil storage tank for charging liquid, and an auxiliary oil cylinder hydraulic control one-way valve is connected between the bottom of each auxiliary oil cylinder and the bottom of the corresponding auxiliary oil cylinder oil storage tank. On the premise of guaranteeing lifting stability of the lifting platform board, only one liquid charging fuel tank assembly is used, overall manufacturing cost of the large lifting platform is reduced, meanwhile, only one main oil cylinder is used for pushing the lifting platform board to ascend, and therefore, the ascending speed of the lifting platform board is guaranteed as far as possible.
本发明公开一种大型升降平台,包括升降台面、充液油箱组件、顶起升降台面用的主油缸和若干个支撑升降台面用的副油缸,主油缸连接于升降台面底部中心位置处,且各副油缸连接于升降台面底部四周位置处,主油缸与充液油箱组件相连通,且主油缸底部设有与充液油箱组件连通的主油缸液控单向阀,各副油缸均配备有充液用的副油缸储油罐,且各副油缸的底部与相对应的副油缸储油罐的底部之间均连接有副油缸液控单向阀。本发明在保证升降台面的升降平稳性的前提下,只使用一个充液油箱组件有利于降低大型升降平台的整体造价成本,同时,只使用一个主油缸来推动升降台面上升,能尽可能保证升降台面的上升速度。
