The method for disassembling and assembling the suspender of the vertical ship lift large-sized work gate vertical hydraulic hoist according to claim 4, which comprises the following steps: in the fifth step, four-point technical control elements are noticed in the shaft dismounting process: the first point is that in the jacking process of the jack, the pressure change of a hydraulic pump station needs to be concerned constantly, and whether the jacking process is smooth or not is determined through the pressure change; secondly, when the jamming condition of the connecting shaft is determined through the pressure change value of the hydraulic pump station, after the pressure is relieved by the hydraulic jack, the position of the suspender is finely adjusted by the aid of the mechanical jack in an auxiliary matching mode, and the jamming is eliminated; a third point suspender connecting shaft and a shaft sleeve are in clearance fit, the working condition of the jack for fixing the shaft due to the fact that the shaft and the shaft sleeve are just in friction bonding possibly exists at the initial stage of shaft dismounting, and at the moment, a manual knocking mode is needed for auxiliary construction; the fourth point is that in the jack shaft jacking process, the front and back directions of the jack are not allowed to be stayed by constructors, so that safety accidents caused by existing accidents are avoided.
8. The method for disassembling and assembling the suspender of the vertical ship lift large-sized work gate vertical hydraulic hoist according to claim 4, which comprises the following steps: in the sixth step, after the connecting shaft between the first section of the suspender and the second section of the suspender is removed, a crane is used for hanging a steel wire rope to hang a hanging head at the lower part of the suspender, the first section of the suspender swings downstream to a vacant position along the water flow direction, then the suspender rotates by 90 degrees to be placed outside the door slot, and the first section of the suspender is placed in a horizontal state by using the downward auxiliary cooperation of a hydraulic hoist and is placed on the arranged bracket;
before the lower hanging head of the first section of suspender is hung by using a crane hanging steel wire rope and swings to the downstream, the structure of the connecting shaft dismounting upper platform (4) between the suspenders needs to be unlocked and dismounted because the swinging area of the first section of suspender and the connecting shaft dismounting upper platform (4) between the suspenders have interference.
9. The method for disassembling and assembling the suspender of the vertical ship lift large-sized work gate vertical hydraulic hoist according to claim 4, which comprises the following steps: before shaft penetration in the step eight, a hydraulic hoist is used for opening and closing to adjust the matching precision between the oil cylinder hanging head and the second section of hanger rod hanging head in the height direction, and a high-precision horizontal angle square is used for detecting the levelness of the inner wall of a shaft penetrating hole, so that the condition that no blockage exists in the shaft connecting penetrating process is met is ensured; after the shaft penetrating is finished, a connecting shaft between the booms is removed to disassemble and assemble the lower platform (6), a connecting shaft between the booms is removed to disassemble and assemble the upper platform (4), a jack (7) and a hydraulic pump station (9); the device is prevented from being in the operation range of the door body and being spatially interfered with the next working procedure.
10. The method for disassembling and assembling the suspender of the vertical ship lift large-sized work gate vertical hydraulic hoist according to claim 4, which comprises the following steps: in the step ten, the door connecting shaft dismounting platform (14) is composed of two parts, the function of a safety channel is considered when the platform is close to the upstream side, and the platform is firmly connected with the door body temporarily after being arranged in place.
