The invention discloses a novel self-elevating platform of an inner sleeve type tower crane, and belongs to the technical field of tower cranes. The pedal platform comprises a rotary lower supporting assembly, a pedal platform body and a sheet-shaped standard knot, wherein the rotary lower supporting assembly is connected with the pedal platform body through a plurality of steel wire rope slings, the pedal platform body is arranged on the outer side of the sheet-shaped standard knot in a sleeving mode, a guiding device is arranged between the pedal platform body and the sheet-shaped standard knot, and one end of the guiding device is connected with the pedal platform body. Through the guide device, the friction force between the pedal platform and the sheet-shaped standard knot in the ascending or descending process is reduced, the energy and material loss is reduced, and the safety and stability of the pedal platform are improved.
本发明公开了一种新型内套式塔机的自升平台,属于塔机技术领域。踏板平台包括回转下支承总成、踏板平台和片状标准节,回转下支承总成通过多根钢丝绳吊索与踏板平台连接,踏板平台套设在片状标准节外侧,在踏板平台与片状标准节之间设有导向装置,导向装置的一端与踏板平台连接。本发明通过导向装置,减少了踏板平台在上升或下降过程中与片状标准节之间的摩擦力,减少能源和材料损耗,并且增加了踏板平台的安全性和稳定性。
