[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figures 1-15 A large-capacity tank container includes a tank body 1, a frame 3 welded to the outer ring of the tank body 1, a bottom plate 9 welded to the bottom of the frame 3, ladders 2 threadedly installed on both sides of the frame 3, a cross plate 6 threadedly installed on the top of the frame 3, a groove 10 opened on the top of the tank body 1, an inlet 11 provided in the groove 10, a first cover plate 12 hinged to one side of the groove 10, an outlet 14 provided on one side of the bottom of the tank body 1, a second cover plate 13 hinged to the outside of the outlet 14, a fixing frame 5 welded to one side of the tank body 1, and the bottom of the fixing frame 5 threadedly fixed to the bottom plate 9.

[0037] The four corners of the frame 3 are threaded with mounting plates 7, and the mounting plates 7 contain switching components.

[0038] The switching assembly includes a slot 31 inside the mounting plate 7. A circular plate 21 is welded to the upper surface of the mounting plate 7. A first rotating rod 22 is mounted at the bottom center of the mounting plate 7 via a coupling. A first limiting clamp 23 and a second limiting clamp 25 are welded to the first rotating rod 22. The first limiting clamp 23 is located below the second limiting clamp 25. A main lifting rope 24 and an auxiliary lifting rope 26 are welded to both sides of the slot 31 on the first rotating rod 22. The switching assembly includes a vertical plate 30 welded to the top of the mounting plate 7. Two openings 33 are opened on the vertical plate 30. Rotating columns 27 are mounted on both sides of the openings 33 via couplings. Limiting columns 28 are welded between the ends of the rotating columns 27. A through slot 29 is opened in the middle of the limiting column 28.

[0039] Both the first limiting clamp 23 and the second limiting clamp 25 are U-shaped. The main lifting rope 24 extends into the interior of the first limiting clamp 23 and the second limiting clamp 25, and the main lifting rope 24 is arranged to abut against the interior sides of the first limiting clamp 23 and the second limiting clamp 25. Both the main lifting rope 24 and the auxiliary lifting rope 26 extend to the other side of the vertical plate 30 through the through groove 29 opened in the limiting post 28.

[0040] Furthermore, a limiting ring 32 is welded to the other side of the vertical plate 30. The radius of the limiting ring 32 is the same as the radius of the main lifting rope 24 and the auxiliary lifting rope 26.

[0041] Furthermore, the mounting plate 7 has an inner cavity 40 at the bottom of the empty slot 31. The first rotating rod 22 extends into the inner cavity 40, and a rotating disk 42 is sleeved on the first rotating rod 22. A rotating shaft 41 is installed on the bottom inner side of the inner cavity 40 through a coupling. A pawl 43 is hinged on the rotating shaft 41. A half-circumferential ratchet is fixedly provided on the outer ring of the rotating disk 42. A baffle 44 is movably provided in the inner cavity 40. A spring is fixedly provided on the baffle 44 and the rotating disk 42. The spring is welded and fixed to the half-circumferential ratchet on the rotating disk 42.

[0042] Furthermore, a groove is provided at the bottom of the inner cavity 40, and a slider is slidably arranged in the groove. The slider is welded and fixed to the baffle 44, and a locking mechanism is provided on the slider to facilitate the limiting of the baffle 44.

[0043] Furthermore, the slide groove has several pin holes, and the slide block is equipped with an electric push rod. The end of the electric push rod is fitted with a pin, and the pin is set in accordance with the pin hole (not shown in the figure).

[0044] Furthermore, the bottom of the opening 33 is inclined, and the bottom of the limiting post 28 can abut against the inclined bottom of the opening 33.

[0045] The tank body 1 is equipped with an anti-sway component. The anti-sway component includes several connecting plates 15 welded to both sides of the inside of the tank body 1, and U-shaped blocks 16 are welded to the connecting plates 15. Several mounting blocks 19 are evenly arranged at the bottom of the U-shaped blocks 16. Connecting ropes 20 are welded to the bottom of the mounting blocks 19, and floats 17 are connected to the connecting ropes 20. Gaps are left between the floats 17.

[0046] When the liquid sloshes during transport, the floats 17 group moves with the wave and consumes kinetic energy. The float array 17 cuts the continuous liquid surface into several water columns, so that when the sloshing liquid enters the gap between the floats 17, it is forced to break at the gap between adjacent floats 17, splitting the overall lateral flow into several small water columns, thus dissipating energy.

[0047] An auxiliary support assembly is also provided on the base plate 9. The auxiliary support assembly includes a first drive motor installed inside the base plate 9. A rotating ring 35 is installed on the output end of the first drive motor through a coupling. A connecting frame 36 is threaded on the end of the rotating ring 35. A fixing block 8 is fixedly connected to the connecting frame 36. A hydraulic component is installed inside the fixing block 8, and a movable seat 38 is connected through the hydraulic component. A hydraulic oil port is opened on one side of the fixing block 8, and a plug is provided at the end of the hydraulic oil port.

[0048] Furthermore, a fixing ring 37 is welded onto the connecting frame 36. Several locking blocks are evenly arranged on the inner surface of the fixing ring 37. Several limiting grooves 34 are opened on the surface of the fixing block 8. The locking blocks extend into the interior of the limiting grooves 34 and are fixed to the fixing block 8 by threads.

[0049] The hydraulic assembly adjusts the height of the movable seat 38 to compensate for uneven ground. By controlling the rotation of the rotating rings 35 set at right angles on both sides of the same corner, the two movable seats 38 are spread out diagonally to form a stable support surface.

[0050] Furthermore, the surface of the movable seat 38 is provided with several threaded holes 18.

[0051] A support plate 4 is welded onto the frame 3, and the support plate 4 is also welded and fixed to the tank body 1. At the same time, a support frame 39 is set at the bottom of the horizontal plate 6, and the support frame 39 is welded and fixed to the top of the tank body 1. The support plate 4 mainly resists the lateral shear force during transportation, efficiently transfers the load of the tank body 1 to the frame 3, and especially prevents fatigue damage to the weld seams of the tank body 1 caused by the bending moment generated when the liquid is fully loaded.

[0052] Working principle:

[0053] When this device is in use, the solution to be transported is filled into the tank 1. After it is full, it is ready to be lifted onto the transport vehicle by the hoisting device. The main lifting rope 24 and the auxiliary lifting rope 26 installed in the four corner mounting plates 7 are fixed to the hook. Furthermore, the length of the auxiliary lifting rope 26 is slightly longer than that of the main lifting rope 24, and the auxiliary lifting rope 26 does not contact the first limit clamp 23 and the second limit clamp 25. The auxiliary lifting rope 26 does not bear any weight and is lifted by the main lifting rope 24.

[0054] The hoisting device tightens the four main hoisting ropes 24 for hoisting operations. As the main hoisting ropes 24 tighten towards the vertical plate 30, they simultaneously cause the first limiting clamp 23 and the second limiting clamp 25 to deflect towards the vertical plate 30. When one of the main hoisting ropes 24 breaks, the tension in the main hoisting rope 24 instantly disappears, the hook loses its pulling force and automatically disengages, and the main hoisting rope 24 quickly falls off. This causes the force on the first limiting clamp 23 and the second limiting clamp 25 to disappear. The reaction force of the spring on the half-circumference ratchet causes the first limiting clamp 23 and the second limiting clamp 25 to rotate towards the auxiliary hoisting rope 26. When the 25th impacts the auxiliary suspension rope 26, it causes the auxiliary suspension rope 26 to deform. The first limiting clamp 23 and the second limiting clamp 25 cause the auxiliary suspension rope 26 to deflect. At the same time, the limiting post 28 abuts against the bottom of the opening 33, causing the auxiliary suspension rope 26 to be tensioned and begin to bear force. This causes the limiting post 28 to deflect and abut against the inclined surface at the bottom of the opening 33. At this time, the rotating disk 42 in the inner cavity 40 follows the first rotating rod 22 and rotates towards the auxiliary suspension rope 26. This causes the half-circumference ratchet on the outer ring of the rotating disk 42 to rotate, so that the end of the ratchet abuts against the baffle 44, and the pawl 43 is engaged in the ratchet, preventing the spring from pulling the rotating disk 42 in the opposite direction, thus achieving double limiting and fixing.

[0055] The hoisting operation continues using the auxiliary hoisting rope 26. After the operation is completed, the main hoisting rope 24 is replaced and the installation plate 7 is maintained.

[0056] Furthermore, when lifting large-capacity tank containers, the sloshing of the internal liquid significantly reduces stability and increases impact load. Therefore, the tank body 1 and lifting structure for lifting solutions of different capacities are further explained. The main lifting rope 24 and auxiliary lifting rope 26 in the four mounting plates 7 are fixed to different hooks. The lifting device is equipped with four second drive motors (not shown in the figure). Nylon ropes are wound around the ends of the second drive motors, and hooks are welded to the ends of the nylon ropes. The hooks are hooked to different main lifting ropes 24 and auxiliary lifting ropes 26. A high-precision camera is embedded in the bottom of the base plate 9.

[0057] When the tank 1 is fully loaded or half-loaded, the solution inside the tank 1 sways left and right when the hoisting mechanism lifts the frame 3, causing the tank 1 and the frame 3 to sway left and right, which may lead to overturning. The floats 17 float on the surface of the solution, with gaps between adjacent floats 17. The array of floats 17 cuts the continuous liquid surface into several water columns, so that when the swaying liquid enters the gap between the floats 17, it is forced to break at the gap between the adjacent floats 17, splitting the overall lateral flow into several small water columns, attenuating the swaying energy, and thus partially eliminating the swaying force of the solution during hoisting, preventing the tank 1 from tipping over or deflecting, which would affect the normal operation of the hoisting.

[0058] When the tank 1 is empty, the hoisting mechanism pulls the main hoisting rope 24 to transport the tank 1 to the predetermined position. At this time, the camera detects the landing point. If unevenness is detected at the four corners of the landing point, the auxiliary support component is controlled. The first drive motor above the concave area drives the rotating ring 35 to rotate, so that the bottom of the movable seat 38 moves to the bottom plate 9. When the tank 1 and the frame 3 move close to the ground, the staff manually connects the hydraulic oil pipe, and the hydraulic component supports the concave and convex areas, so that the tank 1 and the frame 3 remain stable when placed at the landing point, and the tank 1 is prevented from shaking.

[0059] Furthermore, when the tank 1 is in three different working conditions—empty, half-loaded, and fully loaded—the high-precision camera under the bottom plate 9 will scan the landing area in real time and feed back the elevation difference to the hoisting control system. The second drive motor will then adjust the position of the hook by winding and unwinding the nylon rope, dynamically adjusting the tension and length of the four main hoisting ropes 24 and the four auxiliary hoisting ropes 26 to counteract the overturning moment caused by uneven ground and different liquid volumes.

[0060] When the ground is generally flat but there is a protrusion in the middle, when the tank 1 is empty, the auxiliary support components set at the four corners work synchronously and are connected to the hydraulic oil pipe to control each movable seat 38 to be supported by the ground. At this time, the length of each movable seat 38 extending out is the same.

[0061] When the tank 1 is half-loaded, there are unevenness at the four corners of the ground, and the internal solution shakes a lot. At this time, the second electric motor on the higher side of the diagonal releases the rope, so that the main hoisting rope 24 hooked to it is slightly loosened, thereby controlling each movable seat 38 to contact the ground. When each movable seat 38 is in contact with the ground, the hoisting component stops working and supports the tank 1 through the movable seats 38. At this time, the extension length of the movable seat 38 on the higher side is less than the extension length of the other three movable seats 38.

[0062] Furthermore, when the tank 1 is fully loaded, there are unevennesses at the four corners of the ground. When the tank 1 is lifted to the landing point by the hoisting assembly, the tank 1 is lifted 10 cm off the ground and contacts the ground through the movable seat 38. At this time, the extension length of the movable seat 38 is calculated, and the speed of the second drive motor above the movable seat 38, whose extension length is inconsistent with others, is adjusted to control the tank 1 to keep it level with the ground. At the same time, the hoisting assembly continues to apply the lifting force to prevent the tank 1 from tipping over.

[0063] The system uses a high-precision camera and lidar embedded in the base plate 9 to scan synchronously, and immediately establishes a local coordinate system for the slope, calculates the slope A (0 < A ≤ 8°) and the static friction coefficient μ of the ground (0.55 for concrete, 0.45 for crushed stone, and 0.35 for compacted soil).

[0064] The critical sliding force F = mg * (sinA - μcosA), where m is the weight of the tank and g is the acceleration due to gravity.

[0065] When the ground at the intended landing point is sloping, and the tank 1 is unloaded, by calculating the slope and the friction between the slope and the ground, and by calculating that the critical sliding force of the tank 1 is less than 0, there is no possibility of sliding when the bottom plate 9 of the tank 1 contacts the inclined plate, so it can be placed directly on the slope.

[0066] If the critical downward force of tank 1 is greater than 0, then by controlling tank 1 to be 10cm off the ground and keeping it suspended, the tension of the four main lifting ropes 24 is redistributed. The two main lifting ropes 24 on the higher side are wound up, and the two main lifting ropes 24 on the lower side are released. When the bottom plate 9 contacts the slope, the movable seat 38 is adjusted to be perpendicular to the slope by the first drive motor through the pre-set matching fixing holes on the slope. The threaded holes 18 opened around the movable seat 38 are matched with the fixing holes reserved on the ground. When the movable seat 38 is in contact with the ground, it is fixed by the threads, which further increases the friction and prevents tank 1 from sliding down when unloaded.

[0067] Furthermore, during the ramp lifting process, if the rope breaks when the tank 1 is fully or half-loaded, the main lifting rope 24 breaks, the tension drops to zero, causing the first rotating rod 22 to lose tension. The first limit clamp 23 and the second limit clamp 25 quickly drive the auxiliary lifting rope 26 to tighten, and the auxiliary lifting rope 26 urgently pulls the corner where the main lifting rope 24 broke. At the same time, the second drive motor that applies force to the auxiliary lifting rope 26 increases its speed, while the other three second drive motors decrease their speed. First, the balance between the four corner lifting ropes is ensured to avoid a chain breakage caused by single-point overload. The breakage impact causes violent shaking of the liquid, which is divided into isolated water columns by the float group 17. At the same time, the first drive motor at the bottom drives the movable seat 38 to be perpendicular to the ramp, and at the same time, the hydraulic group Driven by the components, the movable seat 38 quickly contacts the ground, providing further support for the tank 1 and frame 3. When the four corner ropes return to horizontal, one side first contacts the slope, while the hydraulic components retract with the descending speed of the tank 1. At the same time, the movable seat 38 is fixed to the bottom ground by the threads. Then, by slowly loosening the rope on the higher side, the bottom plate 9 comes into contact with the slope, and the movable seat 38 is fixed to the ground by the threads. Furthermore, the liquid is quickly discharged through the liquid outlet 14, making the critical downward force of the tank 1 less than 0. At this time, the second drive motor at the top stops working, causing the three main ropes 24 and one auxiliary rope 26 to loosen. The workers then replace and repair the mounting plate 7 installed by the thread on the top.
