The structure of the port clamping mechanism 5 is consistent with that of the head end clamping mechanism 4.
Fig. 8 shows a flow chart of the invention, and the following describes the working process of the invention in detail with reference to the flow chart and the remaining figures.
When the pontoon starts to be put into use, the autonomous docking process of the pontoon units as shown in fig. 7 is first performed. When the end-to-end butt joint is carried out, the iron cable 5 in the tail end iron cable cabin 26 of the floating bridge A extends out of the tail end iron cable hole 25 to be connected with the head end iron cable connector 210 of the floating bridge B, then the motor in the tail end iron cable cabin 26 of the floating bridge A operates to contract the iron cable 5, and the floating bridge B is pulled towards the floating bridge A. Because the area of the opening of the head end clamping mechanism 4 on the pontoon main body 2 is larger than that of the tail end connecting body 21, the tail end connecting body of the pontoon A can still easily enter the pontoon B even if relative movement exists between the two pontoons. Then, the floating bridge a is fixed in the vertical direction and the horizontal direction by the head end vertical hydraulic clamping column 42 and the head end horizontal hydraulic clamping column 43 of the head end clamping mechanism 4 in the floating bridge B, at this time, the head end iron pin 41 descends into the tail end connecting body iron pin hole 213 on the tail end connecting body 21 of the floating bridge a, then the head end vertical hydraulic clamping column 42 and the head end horizontal hydraulic clamping column 43 of the floating bridge B are loosened, and the head end and the tail end of the two floating bridges are butted. The butt joint process of the two floating bridge sides is consistent with the butt joint process of the head end and the tail end.
After the floating bridge is connected, a worker considers whether corresponding swing reduction measures need to be started or not according to specific sea conditions and floating bridge motion response conditions, and the two swing reduction measures have the following specific working modes.
Fig. 9 is a schematic diagram of the reduction of the water surface area of the floating bridge under severe sea conditions. As shown in the upper part of fig. 9, the water surface area of the pontoon at this time is the horizontal sectional area of the pontoon main body 2, and the pontoon receives a large wave load due to a large water surface area when the sea state is severe, and the motion response is remarkable. At this time the deck 11 is lifted and the ballast water volume of the buoyancy tank 29 is increased, and the pontoon sinks as shown below in fig. 8 because of the reduced buoyancy. At this time, the water line surface area of the floating bridge is greatly reduced to become the area of the bridge deck hydraulic lifting column 12, which is beneficial to reducing the swing motion of the floating bridge.
Fig. 10 is a schematic view of the sway reducing motion of the anti-roll damping net. When the sea condition is severe, the anti-sway damping net 3 is placed under the damping net hydraulic lifting column 32, and the damping net surface 31 of the anti-sway damping net 3 is provided with the regular hexagon through holes, so that the damping during the floating bridge movement can be greatly increased, and the sway movement is reduced.
