A disassembly-free maintenance component for a jacking hydraulic system of a tower crane comprises a hydraulic oil storage tank bottom plate and a screw plug, the screw plug is in threaded fit with a through hole sealing pipe on the hydraulic oil storage tank bottom plate, the upper surface of the screw plug is not higher than the upper surface of the hydraulic oil storage tank bottom plate, and the screw plug is provided with an oil passing column hole. The oil passing column is slidably placed in the oil passing column hole without oil leakage, the top of the oil passing column is not communicated, and the bottom of the oil passing column is communicated with the oil passing hole in the side face of the oil passing column; the upper portion of the oil passing column is pressed on a spigot of the oil passing column hole of the screw plug through an oil passing column elastic component, and the upper surface of the oil passing column is not higher than the upper surface of the screw plug. When oil is discharged, the oil receiving pipe is used for jacking the oil passing column upwards from the lower portion of the oil passing column, the oil passing column compresses the oil passing column elastic component, the oil passing hole formed in the side face of the oil passing column is exposed out of the upper surface of the screw plug, oil flows into the oil receiving pipe from the oil passing hole, and after oil discharging is finished, the oil receiving pipe is pulled out of the oil passing column hole of the screw plug, and the oil passing column elastic component resets the oil passing column.

    一种塔式起重机顶升液压系统免拆维护部件,包括液压油储箱底板和螺塞,螺塞与液压油储箱底板上的通孔密封管螺纹配合,螺塞的上表面不高于液压油储箱底板的上表面,所述螺塞设置有通油柱孔,通油柱可滑动的不漏油地放置于通油柱孔内,所述通油柱顶部不通,所述通油柱底部与侧面有通油孔相通;所述通油柱上方被通油柱弹性部件压在所述螺塞的通油柱孔的止口上,通油柱的上表面不高于螺塞的上表面;当排油时,用接油管从通油柱的下方往上顶通油柱,通油柱压缩通油柱弹性部件,设置在通油柱侧面的通油孔露出螺塞上表面,油从通油孔流至接油管中,排油结束后,将接油管从螺塞的通油柱孔中拔出,通油柱弹性部件将通油柱复位。
