[0002] Regarding the excavation of deep foundation pits of ship locks, in order to ensure the safety and stability of construction, diaphragm wall structures are adopted. The steel reinforcement cages of the diaphragm walls have the following forms in the horizontal section: "one", "┏", "┯", "╋", "", and some special-shaped diaphragm walls are tall and the steel reinforcement cages are heavy, which greatly increases the construction difficulty. The existing steel reinforcement fabrication and installation sites for steel reinforcement cages are fixed, and the steel reinforcement needs to be transferred and hoisted twice. When hoisting large steel reinforcement, the steel reinforcement cage needs to be reinforced to prevent deformation of the steel reinforcement cage, and the process consumes a large amount of labor, time, and high cost. Therefore, it is necessary to provide a new integrated device for hoisting and installing a large steel reinforcement cage to solve the above technical problems. Summary of the Invention
