The invention relates to a segment overturning tongue-and-groove protection device. The device structurally 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 base plate and a clamping rod, wherein the section of the clamping body is in an L shape, the base plate is perpendicularly fixed to one side of the clamping body, the base plate is parallel to the other side of the clamping body, a clamping opening is formed between the base plate and the clamping body, and the clamping rod penetrates through the base plate in a threaded connection mode. The overturning tongue-and-groove protection tool is small and exquisite in appearance and light in weight, can be installed in place through manual lifting in the field operation process, can be installed by tightening the clamping rods, and is very convenient to use; and the problems of tongue-and-groove protection, assembly and disassembly efficiency and the like of segment overturning are solved, meanwhile, a hoisting steel wire rope is effectively protected against damage by the edge of a 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装置,其结构包括夹持部件、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。本发明的翻身企口保护工装外形小巧、重量轻,现场操作时用人力托举就能安装到位,再拧紧夹持杆就可完成安装,非常方便;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。
