However, during use, the width of the chassis is fixed and cannot be adjusted. When facing cryogenic storage tanks with different diameter sizes, the cryogenic storage tank cannot be completely attached to the buffer device body, weakening the buffer effect of the buffer device body.

When facing cryogenic storage tanks with different diameter sizes, the cryogenic storage tank cannot be completely attached to the buffer device body, weakening the buffer effect of the buffer device body.

[0006] To achieve the above object, the present utility model provides the following technical solutions: An adjustable support structure for a low-temperature storage tank, comprising a storage tank and a buffer device body. Both sides of the bottom of the storage tank are provided with bottom plates. The bottom of the buffer device body is fixedly connected to the top of the bottom plate. There are eight buffer device bodies, which are equally spaced and distributed in a rectangle. A support block is fixedly connected to the top of the buffer device body. The two sides of the storage tank are movably connected to the inner sides of the support blocks. Both the front side and the rear side of the inner side of the bottom plate are fixedly connected with first folding frames. A first bidirectional threaded rod is arranged inside the bottom plate. The back of the first bidirectional threaded rod is fixedly connected with a second bidirectional threaded rod. Both sides of the surface of the first bidirectional threaded rod and both sides of the surface of the second bidirectional threaded rod are threadedly connected to the inner wall of the first folding frame. A motor is arranged on the front of the first bidirectional threaded rod. The output end of the motor is fixedly connected to the front of the first bidirectional threaded rod. An auxiliary moving mechanism is fixedly connected to the inner sides of the front and back of the bottom plate.

[0007] Preferably, the auxiliary moving mechanism includes a hydraulic cylinder. The inner side of the hydraulic cylinder is fixedly connected to the inner sides of the front and back of the bottom plate. A shaft rod is fixedly connected to the outside of the front of the bottom plate. A support plate is movably sleeved on the surface of the shaft rod. The inner side of the support plate is movably connected to the outside of the hydraulic cylinder through a shaft pin. The outside of the support plate is movably connected to a roller through a shaft pin.

[0008] Preferably, the front side of the inner side of the bottom plate is fixedly connected with a second folding frame. The inner side of the second folding frame is fixedly connected to the outside of the motor.

[0009] Preferably, the inner side of the support block is inclined. A rubber cushion block is fixedly connected to the top of the support block.

[0010] Preferably, auxiliary fixing rods are movably connected to the tops of both sides of the support block through shaft pins. A rope is arranged at the top of the auxiliary fixing rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the first folding frame, the first double-threaded rod, the second double-threaded rod and the motor, before placing the storage tank on the support block, the user starts the motor, and the output end of the motor rotates the first double-threaded rod and the second double-threaded rod together, so that the first folding frame folds, and thus the bottom plate moves symmetrically, solving the problem that the width of the chassis is fixed and cannot be adjusted. When facing cryogenic storage tanks with different diameters, the cryogenic storage tanks cannot fit perfectly with the buffer device body, weakening the buffering effect of the buffer device body, and achieving the effect of auxiliary adjustment.

[0015] 2. By setting the auxiliary moving mechanism, when the user needs to adjust the inner diameter of the bottom plate according to storage tanks with different diameters, the user starts the hydraulic cylinder, and the piston end of the hydraulic cylinder pushes the connecting rod, so that the connecting rod rotates around the shaft rod as the center of the circle, and at the same time the rollers rotate together, thus lifting the bottom plate and separating it from the ground contact, preventing the folding frame from having too much friction when moving the bottom plate due to excessive contact between the bottom plate and the ground when adjusting the inner diameter of the bottom plate by folding, thereby improving the work efficiency.

[0016] 3. By setting the second folding frame, when the first folding frame folds to adjust the inner diameter of the bottom plate, the second folding frame will fold together, preventing the connecting rod and the rollers from lifting the bottom plate and the motor from also separating from the ground contact, so that the motor has no support point when rotating the first double-threaded rod and the second double-threaded rod, causing the body of the motor to rotate by itself, thereby improving the stability of the motor.

Detailed implementation manner

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 4 shown, an adjustable support structure for a low-temperature storage tank provided by the present invention includes a storage tank 1 and a buffer device body 2. Both sides of the bottom of the storage tank 1 are provided with bottom plates 3. The bottom of the buffer device body 2 is fixedly connected to the top of the bottom plate 3. There are eight buffer device bodies 2 and they are evenly distributed in a rectangle. The top of the buffer device body 2 is fixedly connected to a support block 4. The two sides of the storage tank 1 are movably connected to the inner side of the support block 4. The front side and the rear side of the inner side of the bottom plate 3 are both fixedly connected to a first folding frame 5. A first double-threaded rod 6 is arranged inside the bottom plate 3. The back of the first double-threaded rod 6 is fixedly connected to a second double-threaded rod 7. Both sides of the surface of the first double-threaded rod 6 and both sides of the surface of the second double-threaded rod 7 are threadedly connected to the inner wall of the first folding frame 5. The front of the first double-threaded rod 6 is provided with a motor 8. The output end of the motor 8 is fixedly connected to the front of the first double-threaded rod 6. The front and the back inner sides of the bottom plate 3 are fixedly connected with an auxiliary moving mechanism 9.

[0024] Refer to Figure 2 , the auxiliary moving mechanism 9 includes a hydraulic cylinder 901. The inner side of the hydraulic cylinder 901 is fixedly connected to the front and the back inner sides of the bottom plate 3. The outer side of the front of the bottom plate 3 is fixedly connected to a shaft rod 902. A support plate 903 is movably sleeved on the surface of the shaft rod 902. The inner side of the support plate 903 is movably connected to the outer side of the hydraulic cylinder 901 through a shaft pin. The outer side of the support plate 903 is movably connected to a roller 904 through a shaft pin.

[0025] As a technical optimization solution of the present utility model, by providing an auxiliary moving mechanism 9, when the inner diameter of the bottom plate 3 needs to be adjusted according to storage tanks 1 of different diameters, the user starts the hydraulic cylinder 901. The piston end of the hydraulic cylinder 901 pushes the connecting rod, causing the connecting rod to rotate around the shaft rod 902. At the same time, the roller 904 rotates together, thereby lifting the bottom plate 3 and separating it from the ground contact. This prevents excessive frictional force generated when moving the bottom plate 3 due to excessive contact between the bottom plate 3 and the ground when the first folding frame 5 adjusts the inner diameter of the bottom plate 3 by folding, thus improving work efficiency.

[0026] Reference Figure 1 and Figure 3 , the front side of the inner side of the bottom plate 3 is fixedly connected with a second folding frame 10, and the inner side of the second folding frame 10 is fixedly connected with the outer side of the motor 8.

[0027] As a technical optimization solution of the present utility model, by providing the second folding frame 10, when the first folding frame 5 folds to adjust the inner diameter of the bottom plate 3, the second folding frame 10 will fold together, preventing the motor 8 from being separated from the ground contact after the connecting rod and the roller 904 lift the bottom plate 3, so that there is no support point when the motor 8 rotates the first double-threaded rod 6 and the second double-threaded rod 7, causing the body of the motor 8 to rotate by itself, thus improving the stability of the motor 8.

[0028] Reference Figure 3 , the inner side of the support block 4 is inclined, and a rubber cushion block 11 is fixedly connected to the top of the support block 4.

[0029] As a technical optimization solution of the present utility model, by providing the inner side of the support block 4 to be inclined, when the support block 4 moves together when the bottom plate 3 is adjusted according to storage tanks 1 of different sizes, the inner side of the support block 4 moves symmetrically and obliquely, so that when facing storage tanks 1 of different diameter sizes, the support block 4 can provide a better support surface. By further providing the rubber cushion block 11, it not only increases the contact surface between the support block 4 and the storage tank 1, but also prevents the storage tank 1 from being damaged by sharp edges such as the corners of the support block 4 when the storage tank 1 is pressed down by its own weight when the support block 4 supports the storage tank 1, thus improving the adaptability of the support block 4.

[0030] Reference Figure 3 , the tops on both sides of the support block 4 are both movably connected by pin shafts with auxiliary fixing rods 12. A rope 13 is provided at the top of the auxiliary fixing rod 12. The two ends of the rope 13 are movably connected to the outer side of the auxiliary fixing rod 12, and the surface of the rope 13 is in contact with the surface of the storage tank 1.

[0031] As a technical optimization solution of the present utility model, by providing the auxiliary fixing rod 12 and the rope 13, after the storage tank 1 is placed on the support block 4, the rope 13 is first tied to one side of the auxiliary fixing rod 12, then the rope 13 passes over the top of the storage tank 1, passes through the auxiliary fixing rod 12 on the other side and is lifted, so that the auxiliary fixing rod 12 is symmetrically folded and attached to the storage tank 1. Then the other side of the rope 13 is tied to the auxiliary fixing rod 12, preventing the storage tank 1 from falling and being damaged due to the shaking during transportation of the storage tank 1 causing the contact between the storage tank 1 and the support block 4 to be disengaged because the support block 4 cannot support and limit both sides of the storage tank 1 due to the excessive size of the storage tank 1. Thus, the stability of the storage tank 1 is improved.

[0032] Reference Figure 3 , a rubber gasket 14 is fixedly connected to the inner side of the auxiliary fixing rod 12, and the rope 13 is made of rubber.

[0033] As a technical optimization solution of the present utility model, by providing the rubber gasket 14, when the rope 13 is pulled to symmetrically fold the auxiliary fixing rod 12 and then tied to the auxiliary fixing rod 12, since the rope 13 is made of rubber, before the rope 13 tied to any side of the auxiliary fixing rod 12 is untied, it always rebounds and contracts, so that the auxiliary fixing rod 12 is continuously pulled by the resilience force. In the case of long-term symmetrical folding, it prevents the auxiliary fixing rod 12 from continuously symmetrically folding and squeezing the storage tank 1 due to the resilience force of the rope 13, thus causing the storage tank 1 to jolt and vibrate during transportation and being scratched by the edge of the auxiliary fixing rod 12, resulting in wear. Thus, the service life of the storage tank 1 is improved.

[0034] Reference Figure 2 and Figure 4 , a first solenoid valve 15 is fixedly connected to the outer side of the top of the hydraulic cylinder 901. The first solenoid valve 15 communicates with the hydraulic cylinder 901. A second solenoid valve 16 is fixedly connected to the top of the motor 8. A control panel 17 is fixedly connected to the front side of the top of the bottom plate 3. Both the first solenoid valve 15 and the second solenoid valve 16 are electrically connected to the control panel 17 through wires.

[0035] As a technical optimization solution of the present utility model, by providing the first solenoid valve 15, the second solenoid valve 16 and the control panel 17, when adjusting the inner diameter of the bottom plate 3 according to the diameter of the storage tank 1, the user operates the control panel 17 to first start the first solenoid valve 15 to start the hydraulic cylinder 901, then the connecting rod and the roller 904 move, causing the bottom plate 3 to rise and be disengaged from the ground contact. Then the second solenoid valve 16 is started to start the motor 8. Then the motor 8 rotates the first double threaded rod 6 and the second double threaded rod 7, so that the folding frame is folded to adjust the inner diameter of the bottom plate 3. Finally, the user only needs to operate the motor 8 and the hydraulic cylinder 901 through the control panel 17, improving the work efficiency.

[0036] Working principle and usage process of the utility model: When in use, before placing the storage tank in front of the support block 4, the user first determines the diameter that the bottom plate 3 needs to be adjusted according to the diameter of the storage tank, and starts operating the control panel 17. First, start the first solenoid valve 15 to activate the hydraulic cylinder 901. The piston end of the hydraulic cylinder 901 pushes the connecting rod, causing the connecting rod to rotate around the shaft rod 902. At the same time, the roller 904 rotates together, thus lifting the bottom plate 3 and separating it from the ground. Then, start the second solenoid valve 16, start the motor 8, and then, according to the previously determined diameter of the storage tank 1, decide whether the output end of the motor 8 rotates the first double-threaded rod 6 and the second double-threaded rod 7 clockwise or counterclockwise, so that the first folding frame 5 folds, thereby expanding or contracting the bottom plate 3 and the support block 4 together outward or inward, and finally adjusting to the best position for placing the storage tank 1. Then, reset the connecting rod and the roller 904 through the hydraulic cylinder 901, lower the bottom plate 3, and after it fits with the ground, the storage tank 1 can be placed on the support block 4. After placing it, first tie the rope 13 to one side of the auxiliary fixing rod 12, then pass the rope 13 over the top of the storage tank 1, thread it through the auxiliary fixing rod 12 on the other side and then lift it, so that the auxiliary fixing rods 12 are symmetrically folded and fit with the storage tank 1. Then, tie the other side of the rope 13 to the auxiliary fixing rod 12, thus having the advantage of auxiliary adjustment.

[0037] In summary: For the adjustable support structure for the low-temperature storage tank, by setting the first folding frame 5, the first double-threaded rod 6, the second double-threaded rod 7 and the motor 8, before placing the storage tank 1 on the support block 4, the user starts the motor 8, and the output end of the motor 8 rotates the first double-threaded rod 6 together with the second double-threaded rod 7, causing the first folding frame 5 to fold, so that the bottom plate 3 moves symmetrically, solving the problem that the width of the chassis is fixed and cannot be adjusted. When facing low-temperature storage tanks with different diameter sizes, the low-temperature storage tank cannot fit completely with the buffer device body, weakening the buffering effect of the buffer device body.
