step S10, providing the lift truck 7, the propelling device 5, the three-dimensional jacking machine 10 and the ship body segment 1 to be provided with the propelling device 5, and fixing the ship body segment 1 above the construction plane 6, so that a certain distance is formed between the ship body segment 1 and the construction plane 6, and a space is reserved for the lift truck 7 to pass through. Preferably, the lift truck 7 has a maximum load bearing capacity of 570 t. In this embodiment, the construction platform 6 is a dock, the ship body segment 1 is placed on a docking block protruding at the bottom of the dock, and the ship body segment 1 is supported by the docking block, so that the ship body segment 1 is conveniently fixed.

In the present embodiment, the adjustment of the propelling means 5 in the transverse direction refers to displacing the propelling means 5 in the horizontal direction, and the adjustment of the propelling means 5 in the longitudinal direction refers to displacing the propelling means 5 in the vertical direction. By the installation method, the propulsion device 5 can be installed in normal work, and the operation is simple. The traditional installation method is that the hoisting crane and the hydraulic vehicle are used for installation, for some propulsion devices 5 with larger weight and installation, because the bearing capacity of the hoisting crane and the hydraulic vehicle is limited, a large number of hoisting codes for hoisting are required to be arranged outside the propulsion devices 5, and because the number of hoisting points on the propulsion devices 5 is limited, the hoisting codes are required to be arranged around the gravity center of the propulsion devices 5, a plurality of hoisting cranes are required to be used for simultaneous hoisting, the hoisting speeds of the hoisting cranes are inconsistent in the hoisting process, the gravity center of the propulsion devices 5 is prone to being deviated, and the potential safety hazard is large. By the installation method, the lifting vehicle 7 can be used for enabling the propulsion device 5 to stably ascend, welding and repairing of hanging yards can be avoided, the installation speed is improved, and the three-dimensional jacking machine 10 can be used for accurately adjusting the transverse and longitudinal displacement of the propulsion device 5.

In order to reduce the adjustment of the propulsion device 5 in the horizontal direction above the construction level 6, so that the propulsion device 5 is as close as possible to the installation position of the propulsion device 5, in the step S20, the method further includes the step S21: before the lifting car 7 is used for lifting the propelling device 5 to the first height position, the propelling device 5 is displaced to be below the vertical center line adjacent to the installation position, so that the horizontal adjustment of the propelling device 5 at the first height position is reduced, and the operation difficulty is reduced.
The step S10 further includes a step S11: marking out an installation position ground sample line 2 on the construction plane 6, and aligning the vertical central line of the lift truck 7 with the installation position ground sample line 2 in the process of advancing on the construction plane 6 of the lift truck 7, so that the central line of the lift truck 7 is positioned right above the installation position ground sample line 2.
In order to avoid that the support members for supporting the hull section 1 obstruct the propulsion device 5 from traveling on the construction plane 6, all the support members adjacent to the installation position of the propulsion installation may be removed or moved away, in the present embodiment, as shown in fig. 1, all the support members at FR12 to FR23 rib positions in the hull section 1 are removed, an entry space for the lift truck 7 is reserved on the construction plane 6, the positions corresponding to the construction plane 6 directly below FR12 to FR23 rib positions in the hull section 1 are taken as the traffic area 3 of the lift truck 7, and the projection line of the FR18 rib position line in the hull section 1 on the construction plane 6 is taken as the ground line 2 of the installation position. In a specific operation, the body length direction of the lift truck 7 is arranged in parallel with the rib line of the hull section 1, and the center line of the lift truck 7 is kept to be opposite to the center ground line of the lift truck 7, so that the propelling device 5 needs to be placed in the center area of the lift truck 7 to ensure that the center line of the propelling device 5 is opposite to the center ground line of the lift truck 7 when driving. Wherein the allowable deviation between the central line of the propelling device 5 and the central line of the lifting car 7 is +/-50 mm. In the present embodiment, the center line of the lift truck 7 refers to a center line of the lift truck 7 in the longitudinal direction of the vehicle body.
Specifically, the lift truck 7 is advanced in the port direction of the hull section 1 on the starboard side of the hull section 1 within the traveling region 3.

Wherein, the upper end flange 502 is connected with the lower end flange of the steering device 12 through a flange bolt. In the installation process, in order to avoid the collision between the upper end flange 502 and the ship body segment 1, the upper end flange 502 is provided with a protection device, and after the adjustment of the installation position of the propulsion device 5 is finished, the protection device is detached from the upper end flange 502.
In step S11, a lift car parking ground sample line is marked on the construction plane 6, and a horizontal distance between the lift car parking ground sample line and the center point of the steering device 12 is L1. The lift car parking ground pattern is drawn to provide a reference for the parking position of the lift car 7, and the lift car 7 is parked such that the projection of the center line of the propulsion device 5 on the construction plane 6 is positioned on the installation position ground pattern 2. The lift car parking ground sample line is arranged on the installation position ground sample line 2, and the lift car 7 stops when the front end of the lift car is positioned right above the lift car parking ground sample line. In this embodiment, the horizontal distance L1 between the parking ground line of the lift car and the center point of the rudder unit 12 is 7000 mm.
In this embodiment, the lifting is performed from the right chord to the left side of the hull section 1 until the lift truck 7 stops when the front end of the lift truck is directly above the parking ground sample line of the lift truck, and a specially-assigned person needs to observe the distance between the bottom plate of the hull section and the upper end flange 502 of the propulsion device 5 during the traveling process of the lift truck 7, so as to ensure that the distance between the bottom plate of the hull section and the upper end flange 502 of the propulsion device 5 is L2. Preferably, L2 is 75mm, and within this separation distance, the upper end flange 502 is prevented from colliding with the bottom plate of the hull section during travel of the lift truck 7.

In order to ensure the adjustment accuracy of the three-dimensional lifter 10, the distance of each time of the three-dimensional lifter 10 is transversely shifted is less than 10mm when the transverse fine adjustment is performed. The distance between the upper end connecting part 501 of the propelling device 5 and the hole wall of the mounting cylindrical hole 11 during the transverse fine adjustment is L3, in this embodiment, the L3 is 181mm, and a sufficient mounting space is ensured.
In step S20, a bracket 9 is provided at an upper end of the lift car 7, and the pusher 5 is supported by the lift car 7 via the bracket 9. The lifting height of the lifting car 7 can be increased by arranging the support 9 on the lifting car 7. The support 9 includes the support plate 901 and a support leg 902 connected to the support plate 901, the support plate 901 is welded to the support plate 901 of the lift car 7, the support leg 902 is disposed at an edge of the lift car 7, and the support leg 902 is connected to a lower surface of the support plate 901.

In a specific operation, the base 504 of the propulsion device 5 and the fixed seat are fixed on the support 9 in a welding manner, so that the propulsion device 5 is prevented from sliding on the support 9 in the jacking process. Before welding, the center line of the propelling device 5 and the parallel line of the flange surface are drawn on the propelling device 5. Preferably, the upper end face of the propulsion device 5 is placed horizontally.
In step S30, when the jacking stroke of the three-dimensional jacking machine 10 is smaller than the distance between the first height position and the mounting position, a step-up assisting process is added, where the step-up assisting process is: and after a first heightening auxiliary component 8 is arranged at the upper end of the three-dimensional jacking machine 10, jacking the propelling device 5 to the installation position.

Preferably, the second heightening auxiliary member 4 is provided on a reinforcing beam of the lift car 7. In this embodiment, the second auxiliary raising member 4 is a sleeper, each of which may have a size of 1800 × 400 × 400, and the second auxiliary raising member 4 includes at least eight sleepers, and the upper surface of each sleeper should be as flat as possible. Specifically, the difference in height of the upper surface of the crosstie is less than 10 mm. Of course, in other embodiments, the number and size of the sleepers may be set according to the requirement, for example, the size of each sleeper may also be 1800 × 400 × 500, and the number and size of the sleepers are not limited herein.
After the second lifting auxiliary component 4 is lifted up on the lift truck 7, the lift truck slowly rises to avoid the weight inclination of the propelling device 5.
Step 33: lowering the three-dimensional jacking machine 10 by a height H2, arranging the first elevating auxiliary component 8 at the upper end of the three-dimensional jacking machine 10, jacking the first elevating auxiliary component 8 to the second height position, and then jacking the propelling device 5 from the second height position to the installation position, wherein the height H2 is greater than the height H1. Specifically, when the stress on the upper surface of the lift truck 7 is 300 to 310t, that is, when the propulsion device 5 reaches the second height position after the propulsion device 5 is lifted by the second lifting auxiliary component 4, the lift truck 7 stops lifting, and the three-dimensional jacking machine 10 descends.

However, in other embodiments, the distance between the second position and the construction level 6 may be smaller than the distance between the installation position and the construction level 6.
After the propulsion device 5 is lifted to the installation position, the horizontal position of the propulsion device 5 is adjusted by the three-dimensional lifting machine 10, so that the upper surface of the upper end flange 502 of the propulsion device 5 is relatively horizontal to the lower surface of the rudder device 12. In the adjusting process, all the three-dimensional lifters 10 may be adjusted at the same time, or a part of the three-dimensional lifters 10 may be adjusted, and the adjustment manner of the three-dimensional lifters 10 is not particularly limited as long as the upper surface of the upper end flange 502 of the propulsion device 5 and the lower end flange of the rudder unit 12 are relatively horizontal.
In order to ensure that there is enough installation space between the propulsion unit 5 and the side wall of the installation cylindrical hole 11, while the upper surface of the upper end flange 502 of the propulsion unit 5 is relatively level with the lower surface of the steering unit 12, because the upper end flange 502 is convexly arranged outside the upper end connecting part 501, in order to avoid the edge of the propulsion unit body 503 colliding with the hole wall of the installation cylindrical hole 11, the distance between the edge of the propulsion unit body 503 and the hole wall of the installation cylindrical hole 11 is L6.
