[0017] Beneficial effects

[0018] The present invention provides a stackable fuel tank container and its operating method. Compared with the prior art, it has the following advantages:

By locking the four sides of the fuel tank box assembly installation end, a quick anti-slip effect is achieved, preventing the fuel tank box assembly from loosening due to shaking, thereby reducing safety hazards.

[0020] (2) The stacked fuel tank box and its working method are as follows: by arranging two sets of brackets in the device, moving the first rotating rod to make the mounting plate fit with the upper end of the third guide block, fixing the mounting plate to the third guide block by the first bolt, moving the second rotating rod to make the fixing plate fit with the fourth guide block, fixing the fixing plate to the fourth guide block by the second bolt, thereby forming a triangular support structure at the edge of the support frame. The above structure can also be connected with the first guide block and the second guide block between adjacent fuel tank box components to form a triangular structure, thereby improving the stability around the locking end of the device.

[0021] (3) The stacked fuel tank box and its working method, by setting a slope on the guide block, setting inclined surfaces with the same slope near the middle of the base on the first guide block, the second guide block, the third guide block, and the fourth guide block, play a guiding and limiting role when one group of fuel tank box components are connected to the base, and when two groups of fuel tank box components are connected to each other, reducing the impact of the displacement of the fuel tank box components on the positioning accuracy, and facilitating subsequent locking and supporting operations.

[0035] The second embodiment differs from the first embodiment mainly in that:

[0036] The first bracket 23 includes a connecting block 231 fixedly connected to the support frame 21. The connecting block 231 is rotatably connected to a first rotating rod 232. The first rotating rod 232 is fixedly connected to a mounting plate 233 at an end away from the connecting block 231.

[0037] The mounting block is rotatably connected to a second rotating rod, and the second rotating rod is fixedly connected to a fixing plate on the side away from the mounting block. An array of second bolts is threadedly connected to the edge of the fixing plate. A plurality of second screw holes matching the second bolts are provided on the upper side of the first guide block 27 and the upper side of the fourth guide block 4. The first rotating rod 232 is moved to allow the mounting plate 233 to fit with the upper end of the third guide block 3.

[0038] The third embodiment differs from the second embodiment mainly in that:

[0039] The first guide block 27, the second guide block 28, the third guide block 3, and the fourth guide block 4 are provided with inclined surfaces with the same slope near the middle of the base 1; by providing inclined surfaces with the same slope near the middle of the base 1 on the first guide block 27, the second guide block 28, the third guide block 3, and the fourth guide block 4, a guiding and limiting function is played when one set of fuel tank box assemblies 2 is connected to the base 1, and when two sets of fuel tank box assemblies 2 are connected to each other.

[0040] The present invention also provides a method for using a stacked fuel tank container, which specifically includes the following steps:

[0041] Step 1: The user hangs the traction end of the external lifting equipment on the array lifting ring 29, and moves the entire fuel tank box assembly 2 to the upper side of the area formed between the two sets of third guide blocks 3 and fourth guide blocks 4 through the external lifting assembly, and adjusts the height of the fuel tank box assembly 2. When the four sides of the bottom of the support frame 21 inside the fuel tank box assembly 2 are in contact with the third guide blocks 3 and the fourth guide blocks 4 respectively, the fuel tank box assembly 2 slides onto the base 1 as a whole under the action of the inclined surfaces of the third guide blocks 3 and the fourth guide blocks 4, and starts the dual-axis motor 251. The dual-axis motor 251 drives the two sets of first bidirectional screws 253 to rotate respectively through the two sets of bevel gear assemblies 252. The two sets of rotating first bidirectional screws 253 drive the two sets of first anti-slip frames 254 to move in the opposite direction, so that the two sets of first anti-slip frames 254 are respectively inserted into the fourth anti-slip grooves in the two sets of fourth guide blocks 4 to a suitable depth;

[0042] Step 2. In step 1, when the two groups of first anti-slip frames 254 are inserted into the two groups of fourth guide blocks 4, the single-axis motor 261 is started, and the single-axis motor 261 drives the second bidirectional screw 263 to rotate through the pulley assembly 262. The rotating second bidirectional screw 263 drives the two groups of second anti-slip frames 264 to move in opposite directions along the guide rod 265. After the two groups of second anti-slip frames 264 are respectively inserted into the third anti-slip grooves in the two groups of third guide blocks 3 to a suitable depth, the single-axis motor 261 is turned off, and the first rotating rod 232 is toggled to make the mounting plate 233 fit with the upper end of the third guide block 3, and the mounting plate 233 is fixed to the third guide block 3 by the first bolt 234. Repeat the above operation to install the second bracket 24 on the fourth guide block 4, separate the hoisting assembly from the group of fuel tank box assembly 2, and repeat the above steps for the other One group of fuel tank box assemblies 2 is hoisted to the upper end of the area between the two groups of first guide blocks 27 and second guide blocks 28 in the original fuel tank box assembly 2, and the other group of fuel tank box assemblies 2 is moved downward. After the first guide blocks 27 and the second guide blocks 28 guide the fuel tank box assemblies 2 to the upper side of the original fuel tank box assembly 2, the above-mentioned locking operation is repeated, and the first anti-slip frame 254 and the second anti-slip frame 264 in the fuel tank box assembly 2 are respectively inserted into the first anti-slip groove in the first guide block 27 and the second anti-slip groove in the second guide block 28, and the first bracket 23 and the second bracket 24 are respectively connected to the second guide block 28 and the first guide block 27 to realize the stacking and installation of the fuel tank boxes. The working principle of the fuel tank box body 22 is the existing technology, so its internal specific structure and working principle are not repeated here.

[0043] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0044] In step 2, since a magnet is installed inside the mounting plate 233, when the first bracket 23 is not needed, the first rotating rod 232 is rotated to fit the mounting plate 233 with the support frame 21. Under the adsorption of the magnet, the mounting plate 233 is adsorbed on the support frame 21.
