The change of the water level causes the real-time change of the step 5, and the step 5 is always kept in a horizontal state. And in the dry period, the leveling mechanism is at the maximum value of leveling.
As shown in fig. 7, in the flood period, the river is at a high water level, the landing height between the shore and the ship is minimum, the angle of the steel approach bridge is minimum or becomes a negative angle, the hinge joint 22 rotates around the connecting shaft 11, the contact position between the leveling hole 21 and the connecting shaft 11 is changed, the hinge joint 22 and the clamping plate 23 are driven to move, and the clamping plate 23 drives the stepping 5 to integrally rotate through the pulling plate 57, so that the angle (mainly the angle of the panel 52) of the stepping 5 is changed. The size of the leveling hole 21 on the hinge joint 22 determines the rotation angle of the stepping 5, and the centering position of the leveling hole 21 and the connecting shaft 11 is set to ensure that the stepping 5 is suitable for the angle change of the steel approach bridge 4 in a larger range, so that the requirement that the stepping 5 always keeps horizontal when the steel approach bridge 4 in the design standard of the pontoon is at different angles is met.
The upper reinforcing rod 61 and the lower reinforcing rod 62 are hinged at the upper end and the lower end of the stepping 5 to form a parallelogram mechanism, so that the linkage of all the stepping 5 can be ensured, and the shaking problem caused by stepping on the single stepping 5 due to the tiny gap of the single stepping 5 is avoided.
