The invention provides a self-locking hook for cable replacement construction and an operation method of a self-locking hook, and relates to the technical field of power construction device. The self-locking hook for cable replacement construction comprises a first hook flap and a second hook flap, and one end of the first hook flap is rotatably connected with one end of the second hook flap; one of the other end of the first hook flap and the other end of the second hook flap is provided with a locking piece, and the other one of the other end of the first hook flap and the other end of the second hook flap is provided with a locked piece; when the first hook flap and the second hook flap are closed, the locked piece is locked by the locking piece, and the upper half section of the first hook flap and the upper half section of the second hook flap form a first clamping hole; a second clamping hole is formed by the lower half section of the first hook flap and the lower half section of the second hook flap, and an elastic piece enabling the clamping space of the first clamping hole to be variable is arranged in the first clamping hole. Clamping of a pulling rope and buckling of a wire can be completed at the same time through one-time locking operation, the construction efficiency is improved, particularly, slippage of the pulling rope due to diameter change can be effectively avoided, and the construction reliability is improved.

    本发明提供一种用于拆换线施工的自锁挂钩及其作业方法,涉及电力施工装置技术领域,用于拆换线施工的自锁挂钩包括第一钩瓣和第二钩瓣,第一钩瓣的一端与第二钩瓣的一端可转动连接,第一钩瓣的另一端和第二钩瓣的另一端中的一个设置有锁件、另一个设置有被锁件,在第一钩瓣与第二钩瓣相闭合时,锁件锁住被锁件,且第一钩瓣的上半段与第二钩瓣的上半段形成第一夹持孔,第一钩瓣的下半段与第二钩瓣的下半段形成第二夹持孔,其中,第一夹持孔内具有使第一夹持孔的夹持空间可变的弹性件。本发明能够通过一次锁闭操作同时完成牵引绳的夹持和导线的环扣,提高施工效率,特别是能够有效避免牵引绳因直径变化而发生的滑移,提高施工的可靠性。
