The invention relates to a segment overturning tongue-and-groove protection method. The method is based on a tongue-and-groove protection device. The tongue-and-groove protection device comprises clamping components and a protection component, wherein the protection component is fixed to one sides of the clamping components, and the protection component is a tubular curved surface. Each clamping component comprises a clamping body, a seat plate and a clamping rod, wherein the section of the clamping body is in an L shape, the seat plate is vertically fixed to one side of the clamping body, theseat plate is parallel to the other side of the clamping body, a clamping opening is formed between the seat plate and the clamping body, and the clamping rod penetrates through the seat plate in a threaded connection manner. The tongue-and-groove protection device is installed at the tongue-and-groove position of a segment, and a hoisting rope is laid along the surface of the protection component. The problems of tongue-and-groove protection, assembly and disassembly efficiency and the like of segment overturning are solved, meanwhile, the hoisting steel wire rope is effectively protected against damage by the edge of the tongue-and-groove, segment precision control is facilitated, and the safety of hoisting operation is improved.

    本发明涉及一种分段翻身企口保护方法,该方法基于一种企口保护装置,企口保护装置包括夹持部件、防护部件,防护部件固定在夹持部件一侧,防护部件呈管状曲面;夹持部件包括夹持主体、座板、夹持杆,夹持主体截面呈L型,座板垂直固定在夹持主体一侧,座板和夹持主体另外一侧平行,座板和夹持主体之间形成夹持口,夹持杆螺接穿过座板;将该企口保护装置安装在分段的企口位置,吊装绳索沿防护部件表面铺设。本发明解决了分段翻身的企口保护、装拆效率等问题,同时也有效保护起重钢丝绳不被企口边缘损坏,有利于分段精度控制和提高起重作业的安全性。
