The invention relates to an internal wiring lifting mast based on rigid chain transmission and application thereof. The internal wiring lifting mast comprises a base, an outer barrel, a middle barrel,an inner barrel, a limiting block, an outer barrel upper end cover, a middle barrel upper end cover, a stable table connecting disc, a lubricating adjusting gasket, a middle barrel lower end cover and an inner barrel lower end cover which are arranged from bottom to top. One end of a rigid chain is connected with the bottom of the inner barrel through a pin shaft, and the rigid chain can implement lifting and withdrawing actions in the working process; during lifting, a chain wheel is driven to rotate clockwise; and wheel teeth and wheel grooves of the chain wheel are in engagement with a rotating shaft of the rigid chain to drive shaft sleeves, positioning blocks and chain plates, and the shaft sleeves on the two sides of the rigid chain move synchronously. The shaft sleeves are pushed by the chain wheel to move along a guide surface of a guide rail. According to the internal wiring lifting mast based on rigid chain transmission, traditional inhaul cable type and self-standing type structural types are replaced, rigid chain transmission is adopted, and the whole lifting mast has the advantages of being simple in structure, low in failure rate, low in price, reliable in performance, long in service life, convenient to maintain and the like.
本发明涉及一种基于刚性链传动的内走线升降桅杆及其应用,包括由下而上设置的底座、外筒、中筒、内筒、限位块、外筒上端盖、中筒上端盖、稳台连接盘、润滑调整垫片、中筒下端盖和内筒下端盖;刚性链一端通过销轴与内筒底部连接,工作过程中刚性链可以实现举升和撤回两个动作,举升时,驱动链轮顺时针转动,链轮的轮齿和轮槽与刚性链的转轴啮合,带动轴套、定位块及链板,刚性链两侧的轴套同步运动,轴套在链轮的推动下沿着导轨的导引面运动。本发明基于刚性链传动的内走线升降桅杆,替代了传统的拉索式和自立式结构型式,采用刚性链传动,整个升降桅杆具有结构简单、故障率低、价格便宜、性能可靠、寿命长、维修方便等优点。
