The invention discloses a high-altitude automatic unhooking device for hoisting an electric power iron tower, which can realize quick connection between a preassembled part of the iron tower and a lifting hook of a crane during installation of the electric power iron tower and quick separation from a preassembled tower body part by pulling a separation rope after hoisting is completed. The electric iron tower hoisting and unhooking device comprises a lifting hook body, a hoisting belt, a hoisting ring, a locking structure, an unlocking structure and the like. The hanging belt and the hanging ring are wound around the angle steel of the preassembled tower body through the hanging belt and then jacked into the locking structure, and the hanging hook is connected with the preassembled tower body part. A hanging ring of the unhooking device is connected with a crane hook through a steel wire rope, the crane hook is lifted, and the unhooking device is locked through the dead weight of the tower body. And when the pre-assembled iron tower is butted, the crane hook is lowered, a ground installation worker pulls the separation rope to trigger the unlocking structure, the lifting belt and the lifting ring are separated from the lifting hook, and the crane hook is lifted to finish separation of the lifting hook device and the tower body.
本发明公开了一种吊装电力铁塔的高空自动脱钩装置,可以实现在电力铁塔安装时,快速连接铁塔预装部分与吊车吊钩,吊装完成后,拉拽脱离绳,迅速与预装塔身部分脱离。电力铁塔吊装脱钩装置包括吊钩本体、吊带与吊环,合锁结构与开锁结构等。吊带与吊环通过吊带绕过预装塔身角钢,然后顶入合锁结构,完成吊钩与预装塔身部分连接。脱钩装置的吊环通过钢丝绳缆与吊车吊钩连接,吊车吊钩上提,通过塔身自重锁紧脱钩装置。当预装铁塔对接完毕,吊车吊钩下放,地面安装工人拉拽脱离绳,触发开锁结构,吊带与吊环的吊环脱离吊钩,吊车吊钩上提,完成吊钩装置与塔身的脱离。
