Each rolling assembly includes a crossbeam 21, a connecting rod 22, two suspension rods 23 and two load wheels 24. The crossbeam 21 extends along the second direction Y and is connected to the two inner sides of the truss platform 1 perpendicular to the second direction Y. The connecting rod 22 is suspended and fixed directly below the crossbeam 21 along the second direction Y through two suspension rods 23. The two load wheels 24 are respectively rotatably arranged at both ends of the connecting rod 22. The highest points of the two load wheels 24 are lower than the bottom surface of the truss platform 1 and the crossbeam 21.

[0023] The steering bearing 4 is arranged between the two suspension rods 23 of the second rolling assembly 3 , and the bottom surface of the inner ring 41 of the steering bearing 4 is fixed to the top surface of the connecting rod 22 of the second rolling assembly 3 .

[0024] The steering link 5 is fixed to the outer side of the outer ring 42 of the steering bearing 4 and is used to drive the outer ring 42 of the steering bearing 4 to rotate relative to the inner ring 41 of the steering bearing 4 .

[0025] Optionally, the inner frame of the truss platform 1 is provided with a plurality of cross braces 11 for connecting the inner frame of the truss platform 1 and all the cross beams 21. This facilitates the overall reinforcement of the truss platform and balances the forces at various locations.

[0028] Optionally, the platform vehicle 100 further includes at least one third rolling assembly 6. The structures of all third rolling assemblies 6 are the same as those of the first rolling assembly 2. All third rolling assemblies 6 are arranged between the first rolling assembly 2 and the second rolling assembly 3. This facilitates more stable transfer of ship segments.

[0029] Optionally, the steering link 5 is V-shaped, and the two ends of the V-shaped opening of the steering link 5 are symmetrically fixed to the outer 42 side surfaces of the outer ring of the steering bearing 4. This facilitates the stable rotation of the outer ring of the steering bearing.

[0030] Optionally, the upper surface of the steering bearing 4 is lower than the bottom surface of the truss platform 1 and the crossbeam 21 of the second rolling assembly 3. This facilitates the rotation of the outer ring of the steering bearing.

[0031] Optionally, the upper surface of each cross beam 21 is flush with the upper surface of the truss platform 1. This makes it easier for the upper surface of the truss platform to stably carry the ship segments.

[0032] Optionally, the lower surface of each cross beam 21 is flush with the lower surface of the truss platform 1. This makes the structure of the truss platform more stable.
