The invention discloses a hooking tool type lifting point device for self-climbing tower crane supporting beams, which comprises a plurality of supporting beams and lifting point assemblies, the lifting point assemblies are distributed on the plurality of supporting beams, each lifting point assembly comprises a connecting frame and a movable rod, the connecting frames are oppositely arranged on the two sides of the plurality of supporting beams, and the movable rods are arranged on the connecting frames. The movable rod is movably arranged in the connecting frame, when the movable rod is located in the connecting frame, the movable rod is a direct stress part of the lifting hook device and is matched with the lifting hook device to lift the supporting beam, and when the movable rod is pulled out of the connecting frame, the lifting hook device can penetrate through the connecting frame to a lifting point assembly of the next layer of supporting beam. According to the scheme, through the mechanism design, the lifting hook of the electric hoist can vertically penetrate through the lifting point of the supporting beam and directly reach the lifting point of the supporting beam on the next layer, the electric hoist does not need to be additionally arranged on the upper supporting beam, the overall dead weight of the supporting beam system is reduced, the load of jacking pressure of a tower ceiling lifting section is reduced, and therefore the equipment cost is reduced.
本发明公开了自攀爬吊塔支撑梁的可穿钩工具式提升吊点装置,其包括若干支撑梁,提升吊点组件,所述提升吊点组件分布于若干支撑梁上,所述提升吊点组件包括连接框架以及活动杆,所述连接框架相对设置于若干支撑梁两侧,所述活动杆可移动地设置于连接框架内,所述活动杆位于连接框架内时,为吊钩装置的直接受力部位,与吊钩装置配合对支撑梁进行提升,所述活动杆抽出连接框架时,吊钩装置可穿过连接框架至下一层支撑梁的提升吊点组件。本方案通过机构设计,电葫芦吊钩可垂直穿过支撑梁吊点,直接到达下一层的撑梁吊点,无需额外在上支撑梁上再设置电葫芦,减轻了支撑梁系统的整体自重,减少塔吊顶升节顶升压力的负担,从而降低了装备成本。
