The invention discloses a hydraulic single-box telescopic translation mechanism and a hydraulic single-box translation lifting appliance. The hydraulic single-box telescopic translation mechanism comprises a bottom beam, a translation push rod, a translation oil cylinder, a telescopic oil cylinder, a hook structure, a hook oil cylinder and a stretching beam, the translation push rod is connected with a small cross beam on the bottom beam through a slide rail; the translation oil cylinders are arranged at the two ends of the translation push rod and used for pushing the translation push rod to conduct translation in the cart direction. The telescopic oil cylinders are arranged at the two ends of the translation push rod and used for driving the stretching beam to stretch out and draw back. The hook structures are arranged at two ends of the translation push rod; one end of the hook structure is connected with the translation push rod, and the other end is connected with the output end of the hook oil cylinder; the hook oil cylinder is mounted on the translation push rod; when the hook oil cylinder stretches out, the hook structure is pushed to be fixedly connected with the telescopic oil cylinder to form a mechanical lock, and when the two translation oil cylinders stretch out and draw back, the translation push rod is pushed to translate in the cart direction. Translation micro-motion in the direction of the cart can be achieved, and the defect that accurate micro-motion of the cart is difficult is overcome.
本发明公开了一种液压单箱伸缩平移机构及液压单箱平移吊具,包括底梁、平移推杆、平移油缸、伸缩油缸、挂钩结构、挂钩油缸和伸梁;平移推杆通过滑轨与底梁上的小横梁连接;平移油缸分设于平移推杆的两端,用以推动平移推杆进行大车方向的平移动作;伸缩油缸分设于平移推杆的两端,用以带动伸梁进行伸缩动作;挂钩结构分设于平移推杆的两端;该挂钩结构的一端与平移推杆连接,其另一端与挂钩油缸的输出端连接;挂钩油缸安装在平移推杆上;该挂钩油缸做伸出动作时,推动挂钩结构与伸缩油缸连接固定形成机械锁,当两平移油缸做一伸一缩动作时,推动平移推杆进行大车方向平移动作。本发明能实现大车方向平移微动,解决了大车很难精准微动的弊端。
