[0013] In the above step 1, the relevant dimensions of each cargo hold wall are measured and recorded. If they are not in accordance with the tolerance, they are corrected, especially the horizontality of the hatch coaming panel. The hatch centerline marks are drawn on both sides and the two end panels of the cargo hold wall;

During the movement, the side wheels roll close to the side walls of the first track under the action of the spring. If the first track is deformed or has a straightness deviation, the first track applies force to the side wheels, and the side wheels act on the springs through the connecting columns and are sensed and recorded by sensors.

The mobile door car assembly is towed by the traction equipment, and the mobile door car assembly moves along the second track through the third roller on the supporting foot. When it reaches the vicinity of the hoisting position, the upper shooting sensor on the lower surface of the mobile platform and the lower shooting sensor on the mobile trolley assembly are used for preliminary positioning. The cargo hold wall is lowered to be temporarily fixed between the clamping plates on both sides, and the clamping plate is pushed by the clamping hydraulic cylinder on the fixed plate to move along the guide rail on the fixed seat, and the cargo hold wall is initially clamped to make it accurately positioned at the top of the slot, and the cargo hold wall continues to be lowered to fall into the slot, and then the clamping plate is driven to clamp the cargo hold wall to complete the hoisting of the cargo hold wall.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is designed with a rapid positioning structure, which uses a through-beam sensor to perform preliminary rapid positioning of the cargo hold wall, and then further realizes precise positioning with the help of a clamping plate, which greatly improves the efficiency and convenience of the installation operation, and significantly speeds up the installation process of the cargo hold wall. The guide rail is systematically and automatically detected by the detection trolley assembly, and the straightness and deformation of the track are comprehensively and accurately checked, and any obstacles that may exist on the track travel path are pre-identified, thereby effectively ensuring the stable advancement of the installation operation. The cargo hold wall is fixed and moved by moving the trolley assembly, and the cargo hold wall is fastened in the slot by the clamping plate, which effectively prevents the cargo hold wall from shaking and tilting during the movement, thereby ensuring the accuracy, safety and reliability of the entire installation process.

After the cargo hold wall is hoisted to a certain height, the hoisting operation is suspended, and a hovering inspection is performed. After confirming that everything is normal, the operation is continued, and the mobile door car assembly (6) is towed by the traction equipment. The mobile door car assembly (6) moves along the second track (10) via the third roller (62) on the supporting foot (61). When it reaches the vicinity of the hoisting position, the mobile platform is used to move the cargo hold wall. The upper beam sensor (67) on the lower surface of the (63) beams against the lower beam sensor (54) on the moving trolley assembly (5) for preliminary positioning, and the cargo hold wall is lowered to be temporarily fixed between the clamping plates (56) on both sides, and the clamping plates (56) are pushed to move along the guide rails (57) on the fixing seat (53) by the clamping hydraulic cylinder (510) on the fixing plate (59), and the cargo hold wall is initially clamped so that it is accurately positioned at the top of the slot (55), and the cargo hold wall is further lowered to fall into the slot (55), and then the clamping plates (56) are driven to clamp the cargo hold wall, and the lifting work of the cargo hold wall is completed.
