After the tension is transmitted to the movable pulley group, the tension is transmitted to the winch and the first mooring post through the movable pulley group.

[0040] How to use this new model:

[0041] The new type is used for loading large modules. When the stern of the ship is docked, a fixed eye 4 is welded on the deck 15 of the ship and connected to a matching shackle 5; the fixed pulley A3 is used to connect the shackle 5; one end of the second mooring rope 2 is fixed to the second mooring post A1, and the other end is connected to the fixed pulley A3 on the ship and transmitted to the fixed pulley B6 on the second mooring post B7, and the fixed pulley B6 has the function of changing the direction of the second mooring rope; the second mooring rope 2 is connected to the connecting handle of the movable pulley block 8 after passing through the fixed pulley B6, and the movable pulley block has the function of saving effort. The movable pulley block 8 is passed around the first mooring rope, and one end of the first mooring rope is fixed to the first mooring post 9; the other end is connected to the winch 10; the winch 10 is fixed on the steel plate 11; a small amount of counterweight 12 required is placed on the steel plate, and the winch 10 tightens the internal steel wire rope to provide the mooring force required for anchoring; the steel plate and the dock ground contact to provide the required friction. As described above, the present invention utilizes the existing mooring posts of the dock, combines the movable pulley block, the friction between the steel plate and the dock floor, and the pulling force of the winch to achieve the purpose of saving counterweight.

[0042] The novel device can provide the mooring force required by different mooring ropes according to the ratio of the movable pulley block and the weight of the counterweight block, has good applicability, and saves a large amount of counterweight block resources. The counterweight block needs to be hoisted onto the steel plate by a crane, and does not need to be cut when removed, so there is no extra waste of resources and it can be reused, which reduces costs and saves manpower.

[0043] Experimental results show that: Taking the FPU project as an example, the friction coefficient between the steel plate and the ground is 0.4. If the traditional mooring method is used, the friction will provide the required mooring force. Taking line 1S as an example, the required counterweight weight is 55 / 0.4=138MT; the required counterweight for each cable is shown in Table 2, and the total counterweight weight is 1595MT. If this new design is used, the total counterweight weight is 280MT. Comparing the two mooring methods, the counterweight saving is close to 82.5%. The weight and cost of the counterweight required for mooring large module ships are greatly optimized.
