The basic column structure 411 is the main load-bearing component of the equipment, which is a rectangular cylinder; the rotating oil cylinder 412 is a component for rotating the rotating leg 413, which is mainly to expand the rotating leg 413 to increase the anti-overturning ability of the invention; the rotating leg 413 is a supporting and anti-overturning component of the equipment; the leg oil cylinder 414 is a main component for supporting and leveling the equipment, and is powered by hydraulic pressure; the connecting single ear 415 and the fixed single ear 416 are the main connecting parts and fixing parts of the lifting device assembly and the modified trailer; the lifting oil cylinder support 417 is a support for connecting the lifting oil cylinder 405 of the middle column assembly.

[0052] like Figure 5 As shown, the middle column assembly 420 includes a middle column structure 421, a lifting cylinder support 422 and four sets of middle column fixed hydraulic pins 423. The middle column assembly is nested in the basic column assembly cylinder, and is pushed by the middle column assembly lifting cylinder 450 for limited extension and contraction; the middle column structure 421 is the main load-bearing component of the equipment, which is a rectangular cylinder; the upper column assembly lifting cylinder support 422 is hingedly connected to one end of the upper column assembly lifting cylinder 460; the middle column fixed hydraulic pin 423 is a load-bearing component that fixes the middle column assembly 420 at the starting position when it is extended and contracted.

[0053] like Figure 6-A , Figure 6-BAs shown, the upper column assembly 430 includes a rotating platform 431, an upper column structure 432, four sets of upper column fixed hydraulic latches 433, a boom assembly connecting ear 434, a boom assembly turning cylinder seat 435, a boom assembly fixed connecting ear 436 and a boom assembly fixed connecting ear hydraulic latch 437. The upper column assembly 430 is nested in the rectangular cylinder of the middle column assembly 420, and is pushed by the upper column assembly lifting cylinder 406 to extend and retract in the middle column assembly 420 to a limited extent; the upper column structure 432 is the main load-bearing component of the equipment, which is a rectangular cylinder; the upper column fixed hydraulic latch 433 is a load-bearing component that fixes the upper column assembly 430 at the starting and end positions when it is extended and retracted. The rotating platform 431 is hydraulically driven and can generally be designed to rotate from -135° to 135°. The boom assembly 5 is rotated to rotate the multi-purpose container spreader assembly 8 to the top of the loading vehicle. The supply vehicle rotating platform 431 is designed with a boom assembly connecting ear 434 and a boom assembly fixed connecting ear 436, which are connected to the boom assembly 5; the boom assembly flip cylinder seat 435 is an articulated seat for installing one end of the boom assembly flip cylinder 404; the boom assembly fixed connection hydraulic pin 437 is used to fix the boom assembly 5 after it is flipped into place.

[0054] like Figure 7-A , Figure 7-B As shown, the boom assembly 5 includes a boom assembly structure 510 and a push cylinder 520. One end of the push cylinder 520 is hinged to the boom assembly structure 510 with a single or double lug, and the other end is hinged to the trolley assembly 6; the extension and retraction of the push cylinder 520 drives the trolley assembly 6 to move linearly.

[0055] like Figure 8-A , Figure 8-B As shown, the boom assembly structure 510 is welded together by a boom steel frame 511, an boom fixing ear 512, a pushing cylinder connecting ear 1 513, an boom connecting ear 514, a boom assembly turning cylinder connecting ear 2 515, and a trolley slide 516; the boom fixing ear 512 and the boom connecting ear 514 are used to connect with the upper column assembly 430 to facilitate the turning and fixing of the boom assembly 5; the trolley slide 516 is used to make the lifting trolley assembly 6 perform linear motion on the boom assembly 5 so that the present invention changes the amplitude during lifting.

[0056] like Figure 9-A , Figure 9-B , Figure 9-CAs shown, the lifting trolley assembly 6 includes a lifting trolley 610, a hydraulic capstan 620, a lifting rope 630, a guide wheel 640, a wire rope fixing pin 650 and a roller 660. The hydraulic capstan 620 is fixed to the lifting trolley 610 by bolts. The hydraulic capstan 620 is a double-coil structure, which can be enclosed in two lifting ropes 630. One end of the lifting rope 630 is fixed and enclosed in the coil of the hydraulic capstan 620. After the lifting rope 630 passes through the guide wheel 640 and the steering wheel 802 in the multi-purpose container spreader assembly 8, the other end is fixed to the wire rope fixing pin 650; the roller 660 is assembled on the four corners of the lifting trolley 610, so that the lifting trolley assembly 6 can roll linearly on the boom assembly 5.

[0057] like Fig.10 As shown, the lifting trolley 610 is welded by a lifting trolley structure 611, a second connecting ear 612 of a pushing oil cylinder, a guide wheel support 613, and a roller mounting hole 614. The second connecting ear 612 of the pushing oil cylinder is used to connect the pushing oil cylinder 520, the guide wheel support 613 is used to guide the lifting rope 630, and the roller mounting hole 614 is used to install the roller 660.

The steering wheel 802 is used to steer the lifting rope 630, and one end of the four short lifting ropes 803 is fixed on the balance bar 801. Since the width of the multi-functional container spreader 804 is consistent with the length of the container, during lifting, the width direction of the multi-functional container spreader 804 is parallel to the length direction of the boom 5. In order to facilitate folding, the balance bar 801 and the multi-functional container spreader are relatively rotated 90°, and the two can be connected together through the cooperation between the latch assembly and the spreader assembly connecting single ear 805 and the spreader assembly connecting double ears 806, which is convenient for folding the spreader assembly. At this time, the length direction of the multi-functional container spreader 804 is parallel to the length direction of the boom 5.

[0059] like Figure 12-A to Figure 12-H As shown, the large-scale ship containerized supply vehicle of the present invention is deployed in the following manner:

[0060] Step 1: After the supply vehicle drives to the dock where the supply is required, it finds the correct position, starts the engine assembly 3, enables the engine assembly 3 to provide power, operates and controls the front hydraulic legs 202 and the rear hydraulic legs 203 to unfold and level the modified trailer 2;

[0061] Step 2: Operate the lifting frame assembly to flip the cylinder support 204, so that the lifting device assembly 4 rotates about 90° around the lifting device assembly connecting ears 205, operate the fixing ear cylinder latch 207 to latch the lifting device assembly fixing ears 206; operate the rotating cylinder 412 to rotate the rotating leg 413 about 135° to increase the anti-overturning ability of the invention, and operate the leg cylinder 414 to adjust to match the front hydraulic leg 202 and the rear hydraulic leg 203;

[0062] Step 3: Operate the boom assembly to flip the cylinder seat 435 to rotate the boom assembly 90 degrees and fix it with the boom assembly fixing connecting ear hydraulic latch 437;

[0063] Step 3: Operate the hydraulic winch 620 to release the lifting rope 630, so that the multi-purpose container lifting device assembly 8 is lowered to the ground;

[0064] Step 4: manually loosen the connection between the single ear 805 and the double ears 806 of the multi-purpose container spreader assembly 8, lift to a certain height to rotate the multi-purpose container spreader 804 by about 90°, connect the short lifting rope 803, and the supply vehicle is basically unfolded;

[0065] If the cargo lifting height requirement is high, continue with the following operations:

[0066] Step 5: Operate the upper column assembly lifting cylinder 460 to lift the upper column assembly 430 to a limited position, and operate the four sets of upper column fixing hydraulic latches 433 to fix the upper column assembly 430;

[0067] Step 6: Operate the lifting cylinder 450 of the center column assembly to lift the center column assembly 420 to a limited position, and operate the four sets of center column fixing hydraulic latches 423 to fix the center column assembly 420.

[0068] Then, the multifunctional container hoist 804 is used to lift the container for replenishment. Fig.13 shown.

[0069] After all the unfolding operations are completed, the retraction of the invention is opposite to the unfolding.
