The threading device comprises a turning rod seat, a wire crossing groove with an upward opening is formed in the turning rod seat, a reverse buckling part is arranged on the portion, located on one side of the wire crossing groove, of the turning rod seat, a turning groove is formed in the portion, located on the other side of the wire crossing groove, of the turning rod seat, a turning rod capable of swinging towards the reverse buckling part is arranged in the turning groove, and the reverse buckling part is used for buckling and locking the bottom of the turning rod; a trigger part is arranged on the crutch rod seat and located at the bottom of the overline groove, one end of the trigger part is rotationally connected with the crutch rod seat, and a clamping groove connected with the bottom of the crutch rod in a matched mode is formed in the trigger part; during operation, one end of a lifting rope is bound to the top of the turning rod, the bottom of the turning rod is clamped with the clamping groove, the turning rod is in a to-be-triggered state, a cable presses against the triggering part to release the turning rod, the bottom of the turning rod is locked with the reverse buckling part, then the threading device is moved downwards, the cable jacks up the turning rod, and the turning rod is in a to-be-triggered state. The whole hanging process is simple and fast, and the hanging line hanging requirement in a complex environment can be met.
本发明公开了一种穿线器,包括拐杆座,拐杆座上设置有朝上方开口的跨线槽,拐杆座上位于跨线槽的一侧设置有反扣部,拐杆座上位于跨线槽的另一侧设置有拐槽,拐槽中设置有可往反扣部摆动的拐杆,反扣部用于扣锁拐杆的底部;拐杆座上位于跨线槽的底部设置有触发部,触发部的一端与拐杆座转动连接,触发部上设置有与拐杆的底部配合连接的卡槽;在作业时,将吊绳的一端绑结在拐杆的顶部,将拐杆的底部与卡槽卡接,使拐杆处于待触发的状态,通过电缆线压靠触发部以释放拐杆,使拐杆的底部与反扣部扣锁,再将本穿线器下移,使电缆线顶起拐杆,以使拐杆带动吊绳的一端跨越过电缆线,以完成挂线动作,整个上挂过程简单快捷,可满足复杂环境的上挂线需求。
