The invention discloses a material lifting device for construction machinery. The material lifting device comprises a base, supporting legs, hydraulic cylinders, moving wheels and supporting plates, wherein the supporting legs are fixedly arranged on the two sides of the bottom end of the base; the hydraulic cylinders are fixedly arranged at the two ends of the base; the moving wheels are arrangedat one ends of the hydraulic cylinders; a fixing plate is arranged at the upper end of the base; the supporting plates are fixedly arranged on the two sides of the upper end of the fixing plate; grooves are formed in the supporting plates; lead screws are arranged in the grooves; threaded blocks are arranged on the two lead screws in a threaded mode; a lifting plate is fixedly connected between the two threaded blocks; and a lifting mechanism is arranged in the fixing plate. Through mutual cooperative use of a buffer plate, a telescopic rod, a fixed base, a connecting rod, a movable plate anda damping spring, the material lifting device can effectively avoid the situation that an entire material carrying box falls to the ground vertically to cause gravity due to accidental sliding of thelifting plate, and consequently equipment use is damaged; and the design achieves the effective buffering and damping effects; and material damage caused by falling and collision of the material carrying box is avoided.

    本发明公开了一种建筑机械物料升降装置,包括底座、支撑腿、液压缸、移动轮和支撑板,底座底端两侧均固定安装有支撑腿,底座的两端均固定安装有液压缸,液压缸的一端均安装有移动轮,底座上端设有固定板,固定板上端两侧均固定安装有支撑板,支撑板内开设有凹槽,且凹槽内设有丝杆,两个丝杆上均螺纹安装有螺纹块,两个螺纹块之间固定连接有升降板,固定板内设有升降机构,通过设置的缓冲板、伸缩杆、固定座、连接杆、活动板和减震弹簧的相互配合使用,可有效避免升降板意外下滑导致整个载料箱垂直落地带来的重力,从而损坏设备使用,该设计达到了有效的缓冲减震效果,避免载料箱跌落碰撞导致物料发生损坏。
