The all-terrain victim transport platform mechanical mechanism of claim 1, wherein: the shapes of the lower end of the lower ball pin (3-4-4) and the upper end of the fixing pin (3-4-5) are cylindrical oblique sections, the two oblique sections are respectively provided with a protrusion and a groove which can be matched, and the lower ball pin (3-4-4) is matched and connected with the oblique section at the upper end of the fixing pin (3-4-5) through the oblique section at the lower end of the lower ball pin.

3. The method of operating an all terrain victim transport platform mechanical arrangement according to any of claims 1-2, wherein:

in the process of flat road running, a wounded person lies on a load platform (3-3), a motor (1-3-2) drives a small belt wheel (1-3-3) to rotate, a belt (1-3-5) drives a large belt wheel (1-3-4) to rotate, a bearing assembly B (1-2-3) drives a reducing hub (1-2-1) to rotate and drives a track (1-4) to rotate, and the advancing, retreating and steering of the all-terrain wounded person transportation platform mechanical mechanism are realized by controlling the speed and the positive and negative of the slope adaptation modules (1) on the two sides;

when the device meets an uphill road surface, when the diameter-variable wheel set (1-2) is in front and the sizing wheel set (1-1) is at back, the radial wheel set (1-2-2) is contracted inwards along the radial direction by controlling a hydraulic system, and simultaneously the large piston rod (1-1-2) is extended out relative to the large cylinder barrel (1-2-4), so that the front end point is pressed downwards and the length is extended under the condition that the connecting line segment of the centers of the sizing wheel set (1-1) and the diameter-variable wheel set (1-2) is kept immovable at the rear end point, and the load platform (3-3) is always kept parallel to the ground in the uphill process;

when a downhill pavement is met, when the diameter-variable wheel group (1-2) is in front and the sizing wheel group (1-1) is in back, the radial wheel group (1-2-2) is ejected outwards along the radial direction by controlling a hydraulic system, and simultaneously the large piston rod (1-1-2) is contracted relative to the large cylinder barrel (1-2-4), so that the front end point is lifted up and the length is shortened under the condition that the connecting line segment of the centers of the sizing wheel group (1-1) and the diameter-variable wheel group (1-2) is kept immovable at the back end point, and the load platform (3-3) is always kept parallel to the ground in the uphill process;

the load platform (3-3) moves up and down by controlling the extension and retraction of the hydraulic cylinder (3-1), so that the acceleration in the vertical direction brought by the process of ascending and descending roads is actively counteracted;

when encountering the road surface with unequal heights on the left side and the right side, passively adjusting the slopes on the two sides to adapt to the height of the module (1) through the deformation of the two groups of parallelogram groups (2-4);

when the road surface is not parallel to the left and right sides, the adaptive modules (1) are deflected automatically relative to the adaptive modules (2) through the slopes on the two sides.
