Novel guiding device of tower crane inner sleeve frame

The utility model discloses a novel guiding device for an inner sleeve frame of a tower crane, which is clamped between the inner sleeve frame and a flaky standard knot and comprises inner sleeve frame angle steel, mounting plates, a guiding block and a mounting component, the mounting plates are vertically fixed on two outer side surfaces of the inner sleeve frame angle steel, and the guiding block is arranged on the mounting component. The guide block is arranged on the mounting plate in a sleeving manner and is detachably fixed through a mounting assembly, so that the mounting plate is positioned in the guide block. The guide device of the inner sleeve frame is improved, the welding mode of the limiting piece is changed into an assembly mode, hard friction is converted into soft friction, sharp point stress in the jacking process is eliminated, the sleeve frame is more stable in the jacking process, and construction of operators is safer. 本实用新型公开了一种塔机内套架的新型导向装置，该导向装置夹持在内套架和片状标准节之间，包括内套架角钢、安装板、导向块和安装组件，所述所述
