In the prior art, the material boarding connection platform is often located above the shipyard dock wall and cannot meet the transportation requirements at the turning circle of the deck in the bilge area. Currently, the permanent ballast is transported to the DECK1 deck in the bilge of the pure car carrier. The DECK1 deck is 7800mm above the dock wall platform surface and 4500mm above the dock bottom. Moreover, the DECK1 deck is located at the turning circle of the deck, and the turning circle of the deck is 3100mm away from the outer side of the vertical side of the ship.

Detailed implementation manners

[0050] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings, rather than all structures.

[0051] In the technical solution of the present invention, a material transportation passage device 3 for a car carrier is provided, which is arranged between the bilge turning circle of the ship and the material transportation system of the car carrier;

[0052] There are 3 openings at the butt joint of the transportation passage device at the bilge turning circle of the ship;

[0053] The transportation passage device 3 is a flat plate type passage, and different structural designs are adopted according to the requirements of the ballast materials to be transported.

[0054] Such as Figure 1 As shown, in an embodiment of the present invention, the transportation passage device 3 is in a "necking type", and the width at one end close to the material transportation system of the pure car carrier is greater than that at the end connected to the bilge turning circle of the ship. Specifically, the width is large (3200 mm) on the side close to the auxiliary platform 1 and small (2000 mm) close to the cabin, showing a necking type. This setting has the following effects: the large width on the side close to the auxiliary platform overlaps on the cabin entry platform, increasing its bearing area, and docking with the auxiliary tray at the end, increasing the transportation width. The small width close to the cabin reduces the hull opening size while ensuring normal transportation contact, reducing damage to the hull and workload. In addition, this design can significantly reduce the weight of this transportation passage device and reduce material loss.

[0055] Such as Figures 1 to 3 As shown, in an embodiment of the present invention, the transportation passage device 3 uses standard section steel, the transverse main beam uses H-shaped steel, the longitudinal auxiliary beam uses channel steel, and steel plates are laid on the top. Guardrails are provided on both sides of the transportation passage device 3 to play a safety protection role.

[0056] Such as Figures 1 to 3 As shown, in an embodiment of the present invention, three support structures 301 are provided at the bottom of the connection between the transportation passage device 3 and the bilge of the hull for connecting to the hull deck.

[0057] Such as Figures 1 to 3 As shown, in an embodiment of the present invention, 2 hanging lugs 302 are provided on each side at both ends of the transportation passage device 3, a total of 8 hanging lugs 302, for hoisting and installing the transportation passage device 3.

[0058] In the technical solution of the present invention, in addition to providing a material transportation passage device for a pure car carrier, a method for installing the above-mentioned material transportation passage device is further provided, and the specific steps are as follows:

[0059] Step 1, Preparation work, fix the material transportation system of the pure car carrier in place, eliminate spatial interference, and draw a warning line in the operation area;

[0060] Step 2, On the dock platform, use a 32T crane to connect the four hanging lugs 301 in the first column and the third column from the left of this transportation passage device 3, and tie traction ropes at the four corners to connect the transportation passage device 3 with the crane;

[0061] Step 3: Since the distance between the ship's side and the dock wall is only 4000, which is the same as the length of the passage device, when hoisting from the dock platform to the dock, ensure that the length direction of the passage device is along the length direction of the dock.

[0062] Step 4: Hoist the transportation passage device 3 above the auxiliary platform and below the bilge turning circle. Pull the towing rope to make it rotate until the narrow end of the passage device approaches the hull, and control the hook to move towards the hull.

[0063] Step 5: Install a hoist at the corresponding position where the DECK2 deck 15 jacks up. Connect one end of it to the two lifting lugs 301 in the fourth column from the left of the passage device, and slowly pull it into the cabin and move it to the predetermined position.

[0064] Step 6: Weld the support at the narrow end of the passage device 3 to the DECK1 deck 14 of the hull, and connect the contact between the wide end of the passage device and the auxiliary platform 1 with a cleat.

[0065] Step 7: Install a hoist at the position where the DECK2 deck 15 jacks up against the outer plate, connect the four lifting lugs in the second and third columns from the left of the passage device to play a role in safety reinforcement. Install two round tube supports at the middle jacking beam of the passage device to play a role in support and stability, and install a transverse support 7 between the support and the longitudinal support 6 of the auxiliary platform 1.

[0074] As Figures 4 to 6 shown, in an embodiment of the present invention, the material transportation system of the PCTC further includes an access platform auxiliary ramp 4, and the access platform auxiliary ramp 4 is arranged in the cabin and connects the transportation passage device 3 with the deck surface. As Figures 7 to 8 shown, it is a structural schematic diagram and a top view of the access platform pallet 2, as Figure 9 shown, it is a top view after the access auxiliary platform 1, the transportation passage device 3 and the access platform auxiliary ramp 4 are connected. In this embodiment, the average load of the access platform pallet 2 is 5 tons. When hoisting, a steel wire rope longer than 10m is used as the lifting rope 9.
