The invention discloses an energy-saving and environment-friendly amplitude-variable oil cylinder of a reach stacker, which belongs to the field of hydraulic oil cylinders and specifically comprises a cylinder barrel, a piston rod, a detachable lug ring, a detachable large cylinder bottom, a detachable core tube assembly and the like, one end of the core tube assembly is fixed on a small cylinder bottom, the other end of the core tube assembly is arranged in an inner cavity of the piston rod, and the core tube assembly can reciprocate relative to the inner cavity of the piston rod. When the variable-amplitude oil cylinder is started in a low-speed no-load mode, oil can be supplied through the energy storage device without an additional oil pump motor device, when the variable-amplitude oil cylinder stretches out and draws back on load, oil can be supplied through the oil pump motor and the energy storage device at the same time, and under the condition of the same stretching-out and drawing-back speed, thrust can be improved by about 30%. The variable-amplitude oil cylinder can be combined with an energy accumulator, motion energy or displacement energy of hydraulic oil is absorbed when the variable-amplitude oil cylinder retracts, the energy is released when the variable-amplitude oil cylinder needs, more work energy can be saved, and the variable-amplitude oil cylinder is of a detachable large-cylinder-bottom structure and is high in maintenance and interchangeability.
本发明公布一种节能环保型正面吊变幅油缸,属于液压油缸领域,具体包含缸筒、活塞杆、可拆卸耳环、可拆卸大缸底及可拆卸芯管组件等,芯管组件一端固定在小缸底上,另一端内置于活塞杆内腔内,芯管组件可相对活塞杆内腔往复运动,在变幅油缸低速空载起动时,可通过蓄能装置供油实现不需要额外的油泵电机装置,当变幅油缸带载伸缩时,可通过油泵电机和蓄能器同时供油,在同等伸缩速度的情况下,推力可提高30%左右,此发明的活塞杆内置芯管组件,可以和蓄能器组合,在变幅缸回缩时时吸收液压油的运动能或者位移能,在变幅油缸需要时又把这些能量释放出来,可提高更加节约工作能量,可拆卸的大缸底结构,维修、互换性高。
