Problems solved by technology
[0002] At present, in the hoisting process of high-voltage transmission towers, manual assisted installation and lifting hooks are mostly used. This requires the installation workers to often climb the tower to the pre-installation position, or the installation workers stand on the hoisted pre-installation tower. This kind of operation method may cause safety accidents in which the installation workers fall, which poses a great safety hazard to the life safety of the installation workers.

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.
Description
technical field [0001] The invention relates to the technical field of electric power tower installation, in particular to a hoisting hook device for a high-voltage transmission tower, and in particular to a high-altitude automatic decoupling device for hoisting an electric power tower. Background technique [0002] At present, in the hoisting process of high-voltage transmission towers, manual-assisted installation and disengagement from hoisting hooks are often used, which requires installation workers to often climb the tower body to the pre-installation position, or the installation workers stand on the hoisted pre-installed tower. This method of operation may cause a safety accident of the installation worker to fall, and there is a great safety hazard to the life safety of the installation worker. SUMMARY OF THE INVENTION [0003] In order to solve the problems existing in the background technology, the purpose of the present invention is to provide a high-altitude a...
