The invention relates to the technical field of building machinery, and discloses a stepless telescopic adjusting lifting platform which comprises a supporting cross beam, an adjusting assembly and a working platform. The two adjusting assemblies are symmetrically distributed, each adjusting assembly comprises a first connecting rod, a second connecting rod, a lead screw and a driven rod, the first end of the first connecting rod is hinged to the fixing base, the second end of the first connecting rod is hinged to the first end of the second connecting rod and the upper end of the driven rod at the same time, and the first end of the lead screw is sleeved with an end base capable of relatively rotating; the end seat is hinged with the second end of the second connecting rod; the second end of the screw rod is in threaded connection with the fixed seat; the two ends of the working platform are hoisted through steel wire ropes which are fixed to the lower ends of the driven rods. The stepless lifting function of the work platform is achieved, adjustment operation is convenient, accurate and timely, an additional power source is not needed, the use flexibility of the work platform is improved, and the field work requirement is met.

    本发明涉及建筑机械技术领域,公开一种无极伸缩调整升降平台,包括支撑横梁、调节组件和作业平台,其中,支撑横梁上设置有两个固定座;两个调节组件对称分布,每个调节组件包括第一连杆、第二连杆、丝杆和从动杆,第一连杆的第一端与固定座铰接,第一连杆的第二端同时与第二连杆的第一端、从动杆的上端铰接,丝杆的第一端套设有能相对转动的端座,端座与第二连杆的第二端铰接,丝杆的第二端与固定座螺纹连接;作业平台的两端分别由钢丝绳吊装,钢丝绳与从动杆的下端固定。本发明实现了作业平台的无极升降功能,调整操作方便、准确、及时,无需额外动力源,提高了作业平台的使用灵活性,满足了现场作业要求。
