The invention discloses a lightning protection grounding device and method for a slewing bearing position of a full slewing tower crane. The lightning protection grounding device is composed of a support device, a grounding sliding shoe device, an annular grounding sliding rail, a grounding down lead and a welding nut. One end of the support device is fixed on an upper bearing base flange plate of a slewing bearing of the full slewing tower crane, the other end of the support device is connected with the grounding sliding shoe device, and the grounding sliding shoe device comprises a compression spring device, a supporting plate and a special-shaped sliding cutter; the compression spring compresses the special-shaped sliding knife on the annular grounding sliding rail through the supporting plate. The annular grounding slide rail is welded on a flange plate of a lower bearing seat of a slewing bearing of the full slewing tower crane; and the flange plate of the upper bearing is connected with the special-shaped sliding knife through a grounding down lead.

    本发明公开了一种全回转塔机回转支承位置避雷接地装置及方法,由支架装置、接地滑靴装置、环形接地滑轨、接地引下线、焊接螺母组成;支架装置的一端固定在全回转塔机回转支承的上承座翼缘板上,另外一端连接接地滑靴装置,接地滑靴装置包括压紧弹簧装置、支撑板、异形滑刀构成;压紧弹簧通过支撑板将异形滑刀压紧在环形接地滑轨上;环形接地滑轨焊接在全回转塔机回转支承的下承座的翼缘板上;上承座翼缘板通过接地引下线与异形滑刀相连。
