The three gorges, the dam and the xi Luo hydropower stations which are currently administered by the Yangtze river electric power have a large number of hydraulic opening and closing machines, the opening and closing machines are operated for a plurality of years, the surface of a piston rod of the opening and closing machines is subjected to local abrasion and corrosion with different degrees, and due to the severe working environment of the opening and closing machines, bolts are corroded, sealing gaskets are aged and the like, and parts are required to be replaced by disassembling the opening and closing machine oil cylinders regularly. The attachments such as abrasion and corrosion of the piston rod not only can cause the damage of the sealing of the oil cylinder in the operation process of the hydraulic hoist, but also can cause the pollution of oil liquid due to the falling object, even cause the blockage and failure of the control valve block, and finally affect the normal opening and closing of the hydraulic hoist. Therefore, the hydraulic hoist cylinder needs to be overhauled regularly.
Because the hydraulic hoist is in a special spatial position environment, and the hoist cylinder is long in length and heavy in weight, when the hoist cylinder is disassembled and assembled, the lifting and overturning process of the cylinder is a difficult point and a great danger source for overhauling the hoist. The currently adopted overturning scheme is to carry out matched lifting operation by a dam crest portal crane and an automobile crane, and has the advantages of high risk, low efficiency and strong dependence on working experience of lifting and command personnel. Therefore, a safe, efficient and movable auxiliary device for overturning the oil cylinder is urgently needed, so that the hoisting and overturning efficiency of the oil cylinder of the hoist is improved, and the operation safety risk and cost are reduced.
For example, chinese patent document CN 113463583B, publication/bulletin day: 2022, 3 and 18 days discloses a field dismounting method for a large-scale oil cylinder of a water inlet accident rapid gate of a high-water-head power station, which is characterized in that the oil cylinder is lifted out of a gate orifice, the overturning and leveling of a dam face are realized, and a safe, efficient and economical dismounting process for completing the dismounting process for the large-scale oil cylinder of the accident rapid gate is adopted, so that the technical problems of long overhaul period, large workload, high operation difficulty and high safety risk of the large-scale oil cylinder of the dismounting process of the high-water-head power station are solved. The hydraulic lifting device is characterized in that the dam crest portal crane is matched with the automobile crane to turn over the oil cylinder, so that the hydraulic lifting device is high in risk and low in efficiency, and has strong dependence on working experience of lifting and command personnel, the lifting belt is loosened and slid, and the portal crane or the crane is overturned due to huge inertial impact of the oil cylinder, so that serious safety accidents occur.
