The invention discloses a hydraulic synchronous lifting system for salvage of sunken ships, and belongs to the technical field of salvage of sunken ships, the hydraulic synchronous lifting system comprises a barge and vertical lifting devices, a moon pool is arranged in the middle of the barge, the vertical lifting devices are uniformly distributed on two vertical side edges of the moon pool, and the vertical lifting devices are arranged along the edge of the moon pool. A steel strand in the vertical lifting device is connected with the arc-shaped beam frame wrapping the sunken ship, the vertical lifting device drives the arc-shaped beam frame wrapping the sunken ship to be lifted synchronously, and the vertical lifting device is connected with the control system through a wire. According to the synchronous lifting system, the large horizontal component force loss caused by horizontal arrangement of a sling in a traditional large piece lifting process is overcome, instability of a lifted object is avoided, and the synchronous lifting process has the advantages that lifting is straight up and down, and no horizontal component force exists.

    本发明公开了一种沉船打捞用液压同步提升系统,属于沉船打捞技术领域,包括驳船和竖向提升装置,驳船中间部位设置月池,在月池的两竖向侧边均布竖向提升装置,竖向提升装置设有多个,竖向提升装置沿月池的边缘设置,竖向提升装置中的钢绞线与包裹沉船的弧形梁框架连接,竖向提升装置带动包裹沉船的弧形梁框架同步提升,竖向提升装置通过导线与控制系统连接。本申请的同步提升系统克服了传统大件吊装工艺吊索水平布置的较大水平分力损失,避免被吊物的失稳,本同步提升工艺提升直上直下,没有水平分力问题。
