Description

Technical Field

[0001] This invention relates to the field of liquid nitrogen tank tilting support technology, and specifically to a liquid nitrogen tank support device with heat insulation function. Background Technology

[0002] Liquid nitrogen is a colorless liquid stored in pressure-resistant steel cylinders. When liquid nitrogen is poured out, it absorbs a large amount of heat as it vaporizes, which can cause frostbite if it comes into contact with the skin.

[0003] Chinese patent CN112628590A discloses a liquid nitrogen pouring device and its pouring method, including a frame, a drive mechanism, a rotating shaft, a liquid nitrogen tank clamp locking mechanism, and a liquid nitrogen funnel. The frame is equipped with a drive mechanism mounting platform and a rotating shaft support frame. The rotating shaft is mounted on the rotating shaft support frame. The drive mechanism is mounted on the drive mechanism mounting platform and drives the rotating shaft to rotate. The upper end of the liquid nitrogen tank clamp locking mechanism is fixedly connected to the rotating shaft. The liquid nitrogen funnel is mounted on the frame. When the drive mechanism drives the rotating shaft to rotate, the rotating shaft drives the liquid nitrogen tank clamp locking mechanism to rotate, causing the narrowed end of the liquid nitrogen tank clamp locking mechanism to align with the liquid nitrogen funnel. However, this device still has the following problems:

[0004] 1. When the liquid nitrogen tank that needs to be supported is heavy, and in order to prevent the device from tipping over when the liquid nitrogen tank is poured out, the device is equipped with a counterweight on the other side of the clamp locking mechanism. In this case, it is necessary to use a hoisting device or additional manual labor to lift the liquid nitrogen tank to the clamp locking position for loading, which is quite inconvenient.

[0005] 2. Furthermore, the flow distance and speed of liquid nitrogen poured out will vary depending on the capacity of the liquid nitrogen tank, making it impossible to accurately control the position of the liquid nitrogen poured onto the material.

[0006] Based on this, the present invention designs a liquid nitrogen tank support device with heat insulation function to solve the above problems. Summary of the Invention

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0039] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-9 A liquid nitrogen tank support device with heat insulation function includes a base plate 1, a movable plate 2, a steering and lifting mechanism 3, a rotating mechanism 4, a liquid pouring and receiving mechanism 5, an adjustable flow guiding component 6, and a weighing platform 7; the left area of ​​the base plate 1 is set as a liquid pouring station; the right area of ​​the base plate 1 is set as a loading and unloading station.

[0040] A steering and lifting mechanism 3 for controlling the pouring height of the liquid nitrogen tank is installed between the base plate 1 and the movable plate 2; the steering and lifting mechanism 3 includes a movable component 32 for controlling the height difference between the base plate 1 and the movable plate 2 and a drive component 31 for controlling the movement of the movable component 32; the drive component 31 is mounted on the base plate 1, and the movable component 32 is mounted on the base plate 1 and the movable plate 2 and connected to the drive component 31.

[0041] The upper end of the movable plate 2 is equipped with a rotating mechanism 4 for controlling the switching of the liquid nitrogen tank between the pouring station and the loading / unloading station;

[0042] The rotating mechanism 4 is equipped with a weighing platform 7; the weighing platform 7 adopts mature technology in the industry, such as the MINEXX3000 weighing platform.

[0043] The weighing platform 7 is equipped with a liquid nitrogen tank pouring and receiving mechanism 5 for convenient clamping and fixing of the liquid nitrogen tank. The liquid nitrogen tank pouring and receiving mechanism 5 includes a clamping component 53 for fixing the liquid nitrogen tank, a flipping component 52 for controlling the movement of the clamping component 53, and a lifting component 51 and a pallet 54 for driving the clamping component 53 to move up and down to facilitate loading and unloading of the liquid nitrogen tank. The lifting component 51 is installed on the weighing platform 7; the flipping component 52 is installed on the lifting component 51; the clamping component 53 is connected to the flipping component 52; and the pallet 54 is installed on the clamping component 53.

[0044] The left end of the movable plate 2 is equipped with an adjustable flow guide component 6 for controlling the liquid flow direction and outlet range when the liquid nitrogen tank is poured out;

[0045] The adjustable flow guide assembly 6 includes a balance frame 61, a tilting flow guide plate 62, a range adjustment assembly 64 for controlling the liquid nitrogen tank outlet range, and a pushing mechanism 65 for controlling the movement of the tilting flow guide plate 62 to facilitate material receiving. The balance frame 61 is fixedly installed on the left end of the movable plate 2; the pushing mechanism 65 is installed on the balance frame 61; the tilting flow guide plate 62 is connected to the pushing mechanism 65, and the range adjustment assembly 64 is installed on the tilting flow guide plate 62.

[0046] In this invention, when the liquid nitrogen tank is not tilted and supported, the base plate 1 and the movable plate 2 are in a folded and retracted state; the clamping assembly 53 is in the loading and unloading position; and at this time, the pallet 54 is flush with the ground; at this time, the reading of the weighing platform 7 is 0.

[0047] When liquid nitrogen needs to be poured from the tank, the operator moves the liquid nitrogen tank to the loading / unloading station and pushes it to the upper end of the pallet 54. Then, the clamping assembly 53 clamps and fixes the liquid nitrogen tank and provides heat insulation. Subsequently, the drive assembly 31 controls the movement of the movable assembly 32. The movement of the movable assembly 32 causes the movable plate 2 to rise upward. The liquid nitrogen tank rises along with the movable plate 2 for initial height adjustment until the height of the movable plate 2 is higher than the material that needs to be cooled with liquid nitrogen. At this time, the reading on the weighing platform 7 is the mass of the liquid nitrogen tank.

[0048] Subsequently, the rotating mechanism 4 drives the clamping assembly 53 to rotate to the left to the liquid pouring station. Then, the lifting assembly 51 drives the clamping assembly 53 to move upward, further adjusting the height of the rotation point when the liquid nitrogen tank is poured, ensuring the accuracy of liquid nitrogen pouring.

[0049] Subsequently, the flipping component 52 works to drive the clamping component 53 to rotate, and the clamping component 53 drives the liquid nitrogen tank to rotate downward together. At the same time, the pushing mechanism 65 works to drive the flipping guide plate 62 to rotate downward.

[0050] Because the volume of liquid nitrogen inside the liquid nitrogen tank is large at this time, the liquid nitrogen flows out at a fast speed and the liquid nitrogen flows out a long distance. At this time, the pushing mechanism 65 works and drives the flipping guide plate 62 to move forward along the balance frame 61. At this time, the liquid nitrogen flows downward to the flipping guide plate 62 and flows downward to the material to be cooled under the action of the range adjustment component 64.

[0051] As the liquid nitrogen continuously flows out of the tank, the outflow speed and distance of the liquid nitrogen gradually decrease. At this time, the pushing mechanism 65 can drive the tilting guide plate 62 to move backward, so that the outflowing liquid nitrogen can flow outward through the tilting guide plate 62. With the downward rotation angle of the tilting guide plate 62, the liquid nitrogen can flow smoothly onto the material. The liquid nitrogen outlet range can also be controlled by the range adjustment component 64.

[0052] As liquid nitrogen is continuously poured, the overall mass of the liquid nitrogen tank decreases, and the reading on the weighing platform 7 also decreases. The operator can then remotely monitor the reading on the weighing platform 7 to monitor the change in the internal volume of the liquid nitrogen tank by observing the change in the mass of the liquid nitrogen tank. This avoids the need for manual observation during the liquid nitrogen pouring process, which could lead to frostbite and further improves the practicality of the device.

[0053] The combination of the rotating mechanism 4, the lifting component 51, the tilting component 52 and the clamping component 53 facilitates the loading of liquid nitrogen tanks, reducing the cost of additional hoisting equipment.

[0054] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figures 1-7 As shown, the drive assembly 31 includes a vertical push cylinder 311 and a fixed shaft 312. The lower ends of the two vertical push cylinders 311 are hinged to the rear side of the upper end of the base plate 1. The fixed shaft 312 is mounted on the movable assembly 32. The output end of the vertical push cylinder 311 is hinged to the fixed shaft 312.

[0055] The movable component 32 includes inner support rods 321, outer support rods 322, and a movable shaft 324. Sliding grooves 323 are symmetrically arranged on the front sides of both the left and right ends of the base plate 1 and the movable plate 2. The lower ends of the two inner support rods 321 are hinged to the rear side of the base plate 1, and the upper ends of the two inner support rods 321 are slidably connected to the sliding grooves 323 on the movable plate 2. The upper ends of the two outer support rods 322 are hinged to the rear side of the movable plate 2, and the lower ends of the two outer support rods 322 are slidably connected to the sliding grooves 323 on the base plate 1.

The mounting plate 41 is fixedly mounted on the upper end of the movable plate 2; the first drive motor 42 is fixedly mounted on the upper end of the mounting plate 41; the drive gear 43 is rotatably mounted on the upper right side of the movable plate 2; the output end of the first drive motor 42 is fixedly connected to the drive gear 43; the rotating disk 44 is rotatably mounted on the upper middle part of the movable plate 2; the driven gear ring 45 is fixedly mounted on the outer end of the rotating disk 44; the drive gear 43 is meshed with the driven gear ring 45; and a weighing platform 7 is fixedly mounted on the rotating disk 44.

[0057] The lifting assembly 51 includes a mounting frame 511, a vertical guide rail 512, a vertical sliding block 513, a hydraulic cylinder 514, and a mounting plate 515. The mounting frame 511 is fixedly installed on the upper end of the weighing platform 7. The vertical guide rail 512 is symmetrically fixedly installed on the front and rear sides of the inner end of the mounting frame 511. The vertical sliding block 513 is limited and slidably connected to the vertical guide rail 512. The hydraulic cylinder 514 is fixedly installed on the upper right side of the mounting frame 511. The front and rear ends of the mounting plate 515 are fixedly connected to the vertical sliding block 513. The output end of the hydraulic cylinder 514 is fixedly connected to the mounting plate 515.

[0058] The flipping assembly 52 includes a second drive motor 521, a driving synchronous sprocket 522, a driven synchronous sprocket 523, a synchronous chain 524, and a movable disk 525. The second drive motor 521 is fixedly installed on the lower inner side of the mounting plate 515; the driving synchronous sprocket 522 is rotatably installed on the lower left side of the inner end of the mounting plate 515; the driven synchronous sprocket 523 is rotatably installed on the upper left side of the inner end of the mounting plate 515; the synchronous chain 524 is wound around the outer ends of the driving synchronous sprocket 522 and the driven synchronous sprocket 523 to enable transmission connection between them; the movable disk 525 is rotatably installed on the upper left side of the mounting plate 515, and the driven synchronous sprocket 523 is fixedly connected to the movable disk 525; the output end of the second drive motor 521 is fixedly connected to the driving synchronous sprocket 522.

[0059] The clamping assembly 53 includes a rotating horizontal plate 531, a bidirectional lead screw 532, a transverse guide rail 533, a transverse sliding block 534, a clamping plate 535, and a first servo motor 536. The rotating horizontal plate 531 is fixedly installed in the middle of the movable disk 525; the bidirectional lead screw 532 is rotatably installed at both ends of the rotating horizontal plate 531; the transverse guide rail 533 is fixedly installed on the lower inner end of the rotating horizontal plate 531; the transverse sliding block 534 is symmetrically and limitly slidably arranged on both the front and rear sides of the transverse guide rail 533; the clamping plate 535 is fixedly installed on the left end of the transverse sliding block 534; the support plate 54 is fixedly installed in the middle of the lower end of the rotating horizontal plate 531 through a connecting rod.

[0060] Both clamping plates 535 have slots at their adjacent ends; and heat-insulating and anti-slip pads are fixedly installed on the slots.

[0061] In this invention, when liquid nitrogen tank pouring operation is required, the worker moves the liquid nitrogen tank to the location of the loading and unloading station and pushes it to the upper end of the pallet 54 to the left. Then, the first servo motor 536 drives the bidirectional lead screw 532 to rotate. The rotation of the bidirectional lead screw 532 drives the two transverse sliding blocks 534 to move inward along the transverse guide rail 533 at the same time. The transverse sliding blocks 534 drive the clamping plate 535 to move inward together until the two clamping plates 535 hold the liquid nitrogen tank tightly and fix it.

[0062] Subsequently, the vertical push cylinder 311 operates. Under the thrust of the vertical push cylinder 311, the two inner support rods 321 rotate upward around the hinge point with the base plate 1. At this time, the upper ends of the two inner support rods 321 move backward along the sliding groove 323 provided on the movable plate 2. Since the inner support rods 321 generate upward thrust when rotating upward, the outer support rods 322 rotate downward around the hinge point with the movable plate 2. At this time, the lower ends of the two outer support rods 322 slide backward along the sliding groove 323 provided on the base plate 1. At this time, the outer support rods 322 and the inner support rods 321 lift the movable plate 2 together. The liquid nitrogen tank follows the movable plate 2 and lifts upward for initial height adjustment until the height of the movable plate 2 is higher than the material that needs to be cooled by liquid nitrogen. At this time, the reading of the weighing platform 7 is the mass of the liquid nitrogen tank.

[0063] Subsequently, the first drive motor 42 operates, driving the drive gear 43 to rotate. The rotation of the drive gear 43 controls the driven gear ring 45 to rotate to the left. The rotating disk 44 rotates together with the driven gear ring 45, causing the liquid nitrogen tank to rotate from the loading / unloading station to the emptying station. Then, the hydraulic cylinder 514 operates, pulling the mounting plate 515 to move upward along the vertical guide rail 512 along with the vertical sliding block 513; further adjusting the height of the rotation point when the liquid nitrogen tank is tilted.

[0064] Subsequently, the second drive motor 521 operates to drive the active synchronous sprocket 522 to rotate. The rotation of the active synchronous sprocket 522 drives the synchronous chain 524 to rotate. The rotation of the synchronous chain 524 drives the driven synchronous sprocket 523 to rotate. At this time, the movable disk 525 will rotate downward together with the synchronous chain 524, causing the liquid nitrogen tank to rotate downward and tilt. The liquid discharge operation is carried out through the cooperation of the flip guide plate 62, the range adjustment component 64 and the pusher mechanism 65.

[0065] Example 3: In some embodiments, as a preferred embodiment of the present invention, such as Figure 8 and Figure 9 As shown, the pushing mechanism 65 includes a transverse pushing cylinder 651, a moving block 653, and a second servo motor 654.

The left and right ends of the tilting guide plate 62 are rotatably connected to the moving block 653. The second servo motor 654 is fixedly installed on the outer end of the left moving block 653, and its output end is fixedly connected to the tilting guide plate 62. The output end of the transverse pushing cylinder 651 is fixedly connected to the moving block 653. The transverse pushing cylinder 651 is fixedly installed on the rear side of the upper end of the balance frame 61.

[0066] The range adjustment assembly 64 includes a control housing 641, a third drive motor 642, a control gear 643, a driven gear 644, and a movable guide plate 645. The control housing 641 is fixedly installed on the upper rear side of the tilting guide plate 62; the control gear 643 is rotatably installed on the upper left side of the tilting guide plate 62; the driven gear 644 is rotatably installed on the upper right side of the tilting guide plate 62; the control gear 643 and the driven gear 644 are meshed; the third drive motor 642 is fixedly installed on the upper end of the control housing 641.

[0067] The control box 641 has symmetrical clearance grooves on the left and right sides of its front end; the upper ends of the control gear 643 and the driven gear 644 are both fixedly mounted with movable guide plates 645; the output end of the third drive motor 642 is fixedly connected to the left movable guide plate 645; the upper end of the flip guide plate 62 has symmetrical movable slots 646 on the left and right sides; the movable guide plate 645 and the movable slots 646 are slidably connected; the front end of the flip guide plate 62 is also provided with a guide hole 647, and the guide hole 647 communicates with the movable slots 646 on the left and right sides;

[0068] In this invention, since the volume of liquid nitrogen inside the liquid nitrogen tank is large at the beginning of the liquid nitrogen pouring, the liquid nitrogen flows out at a fast speed and a long distance. At this time, the transverse push cylinder 651 works to push the moving block 653 forward along the slide 652. The moving block 653 drives the second servo motor 654 and the tilting guide plate 62 to move forward together. At the same time, the second servo motor 654 works to drive the tilting guide plate 62 to rotate downward.

[0069] At this time, the liquid nitrogen flows downward to the flipping guide plate 62, and flows out between the two moving guide plates 645 under the limiting action of the left and right moving guide plates 645.

[0070] As the liquid nitrogen inside the tank continues to flow out, the speed and distance of the liquid nitrogen outflow will gradually decrease. At this time, the horizontal push cylinder 651 works to drive the tilting guide plate 62 to move backward gradually, so that the outflowing liquid nitrogen can always flow onto the tilting guide plate 62 and flow outward.

[0071] When it is necessary to expand the liquid nitrogen outlet range, the third drive motor 642 drives the left movable guide plate 645 to rotate. The rotation of the movable guide plate 645 drives the control gear 643 to rotate, and the control gear 643 drives the driven gear 644 to rotate. At this time, the right movable guide plate 645 will follow the left movable guide plate 645 and rotate outward along the movable groove 646, thereby increasing the distance between the front sides of the two movable guide plates 645 and thus expanding the outlet range. The residual liquid nitrogen flowing into the movable groove 646 will flow outward through the guide hole 647.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
