[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] like Figures 1 to 11As shown in the figure, an embodiment of the present invention provides an adiabatic tank bottom support structure, including an adiabatic tank body 1. To facilitate the support of the adiabatic tank body 1, a mortise and tenon joint component, a positioning and clamping component, and a fitting and limiting component are provided at the bottom of the adiabatic tank body 1; the mortise and tenon joint component includes a support round seat 2 fixedly connected to the center position of the bottom of the adiabatic tank body 1, a clamping mortise frame 3 fixedly connected to the inner side of the support round seat 2, and a plurality of clamping tenon frames 5 clamped and connected to the outer side of the support round seat 2, and the clamping tenon frame 5 is connected to the clamping mortise frame 3; a clamping mortise groove 4 is opened at the end of the clamping mortise frame 3 away from the support round seat 2, and a plurality of clamping tenon grooves 6 are fixedly connected to the inner side of the clamping tenon frame 5, and the clamping tenon groove 6 is clamped and connected to the clamping mortise groove 4 of the clamping mortise frame 3, so as to facilitate positioning the clamping tenon frame 5 on the support round seat 2 in a mortise and tenon manner through the clamping mortise frame 3 and the clamping tenon groove 6.

[0044] The positioning and clamping component is arranged at the end of each clamping tenon frame 5 away from the support round seat 2, and the positioning and clamping component is used in cooperation with the adiabatic tank body 1 and the support round seat 2, so as to facilitate the first-layer simple support of the adiabatic tank body 1 through the positioning and clamping component.

[0045] The fitting and limiting component is connected to the positioning and clamping component and the adiabatic tank body 1. The fitting and limiting component includes a plurality of damping modules distributed circumferentially along the outer periphery of the bottom of the adiabatic tank body 1. Each damping module is connected to the corresponding clamping tenon frame 5 through a linkage mechanism. The damping module includes a contact part elastically attached to the outer wall of the adiabatic tank body 1. By cooperating with the positioning and clamping component and the adiabatic tank body 1, the second-layer cooperative support of the adiabatic tank body 1 is facilitated through the limiting component.

[0046] During operation, when the adiabatic tank body 1 needs to be installed and used, after the adiabatic tank body 1 is adjusted to a suitable position and installation height by an external forklift, the staff sequentially clamps a plurality of clamping tenon frames 5 on the support round seat 2 through the clamping tenon grooves 6 on them with the clamping mortise frame 3 and the clamping mortise groove 4 on the support round seat 2 as mortise and tenon interfaces. Under vibration conditions, the clamping node can dissipate energy through the friction between the clamping head and the connection part, reducing the resonance effect, and thus completing the simple support of the adiabatic tank body 1.

[0047] As Figures 2 to 8As shown, an embodiment of the present invention further provides a bottom support structure of an insulated tank. Different from Embodiment 1, in this embodiment, the positioning clamping assembly includes a connecting seat 7, a connecting arc piece 8, a threaded sleeve 9 and a toggle gear 10. In order to facilitate the movement of the connecting seat 7, the end of the clamping tenon frame 5 away from the supporting round seat 2 is fixedly connected to the connecting seat 7. In order to facilitate the serial fixing of multiple connecting seats 7, multiple connecting arc pieces 8 are arranged on the inner side of the connecting seat 7. The interior of the connecting seat 7 and the position corresponding to the connecting arc piece 8 are rotatably connected with a threaded sleeve 9, and the outer side of the threaded sleeve 9 is fixedly connected with a toggle gear 10.

[0048] In order to facilitate the fixation of the connecting seat 7 and the connecting arc piece 8, the positioning clamping assembly also includes a connecting screw 11, a positioning arc pin 12, a connecting column 13 and a clamping column 14. The inner side of the threaded sleeve 9 is threadedly connected with the connecting screw 11, and the connecting screw 11 is threadedly connected to the connecting seat 7. The bottom of the connecting screw 11 is threadedly connected to the connecting arc piece 8. The top of the connecting screw 11 is rotatably connected to the connecting column 13, which makes it convenient to drive the connecting screw 11 to move up and down in the connecting seat 7 by toggling the toggle gear 10. In order to improve the fixing effect between multiple connecting arc pieces 8 and the connecting seat 7, the end of the connecting column 13 away from the connecting screw 11 is fixedly connected with a clamping column 14, and the bottom of the clamping column 14 passes through the connecting seat 7 and the threaded sleeve 9.

[0049] During operation, after the staff has completed the fitting and positioning of the card-jointed tenon frame 5 and the supporting round seat 2, they place a plurality of connecting arc pieces 8 in the connecting seat 7 in sequence according to the installation position, and the placement is arranged in sequence according to rotation, so that the two ends of a single connecting arc piece 8 are placed in two adjacent connecting seats 7 in sequence, so that they are arranged in series, and then the staff inserts the positioning arc pin 12 into the two adjacent connecting arc pieces 8 in sequence, and simply positions them, and then the staff sequentially toggles the toggle gear 10, and then the toggle gear 10 drives the threaded sleeve 9 therein to rotate , so that the threaded sleeve 9 drives the connecting screw 11 therein to move toward the direction close to the connecting arc piece 8, and then it is connected and fixed with the connecting arc piece 8. While the connecting screw 11 moves toward the direction of the connecting arc piece 8, it drives the connecting column 13 and the clamping column 14 to move toward the direction of the connecting arc piece 8 at the same time, and then the clamping column 14 penetrates the connecting seat 7 and then penetrates the positioning arc-shaped pin 12, so that it can make a second connection to the installed connecting arc piece 8, thereby improving the fixing effect of the connecting arc piece 8 and the connecting seat 7 and reducing the subsequent loosening of the connecting screw 11 due to resonance.

[0050] Under vibration conditions, the clamping joint can dissipate energy through the friction between the clamping head and the connection, reducing the resonance effect. It can achieve multi-directional force transmission through geometric interlocking, avoiding stress concentration at a single connection point such as a weld seam or bolt hole, significantly reducing the risk of fatigue cracking. This reduces the phenomenon of bolt loosening or weld fatigue cracking at the connection between the support structure and the tank body of the insulation tank during its long-term operation, improving the use effect of the device, further reducing the risk of the tank body tilting and being damaged due to bolt loosening, and enhancing the safety of the tank body during operation.

[0051] As Figure 10 and Figure 11 shown, the embodiment of the present invention also provides a bottom support structure for an insulation tank. Different from Embodiment 2, in this embodiment, in order to facilitate the second-layer support for the insulation tank body 1 and the support circular seat 2, the damping module of the fitting and limiting assembly includes a movable support frame 15, a damping frame 16, a fixed damping plate 17, a damping sleeve 18, a metal rubber pad 19, and a resonance spring 20. In order to facilitate the pushing of the support circular seat 2 and the connection seat 7 connected to the support circular seat 2, a movable support frame 15 is fixedly connected to the end of the connection seat 7 away from the clamping tenon frame 5. A damping frame 16 is arranged at the top of the end of the movable support frame 15 away from the clamping tenon frame 5. A fixed damping plate 17 is fixedly connected to the inner side of the damping frame 16 and away from the clamping tenon frame 5. A plurality of damping sleeves 18 are slidably connected to the end of the damping frame 16 close to the insulation tank body 1. A metal rubber pad 19 is fixedly connected to the end of the damping sleeve 18 away from the fixed damping plate 17. The metal rubber pad 19 is in contact with the insulation tank body 1. A resonance spring 20 is fixedly connected to the inside of the damping sleeve 18. The end of the resonance spring 20 away from the insulation tank body 1 is fixedly connected to the fixed damping plate 17, thereby performing second-layer limit support on the insulation tank body 1 through the metal rubber pad 19 and the resonance spring 20.

[0052] In order to facilitate driving the metal rubber pad 19 to move towards the insulation tank body 1, the linkage mechanism of the fitting and limiting assembly includes an adjustment seat 21, a first movable seat 22, a first electric push cylinder 23, and a first output column 24. An adjustment seat 21 is fixedly connected to the bottom end of the damping frame 16. A first movable seat 22 is fixedly connected to the end of the damping frame 16 away from the clamping tenon frame 5. A first electric push cylinder 23 is rotatably connected to the inner side of the movable support frame 15 and away from the clamping tenon frame 5. A first output column 24 is arranged inside the first electric push cylinder 23. The telescopic end of the first output column 24 is rotatably connected to the first movable seat 22.

[0053] The linkage mechanism of the fitting and limiting assembly further includes a second electric push cylinder 25, a second moving seat 26 and a second output column 27. The top end of the adjusting seat 21 away from one end of the clamping tenon frame 5 is fixedly connected with a second moving seat 26. The second electric push cylinder 25 is rotatably connected at a position corresponding to the first electric push cylinder 23 inside the moving support frame 15. A second output column 27 is arranged inside the second electric push cylinder 25. The end of the second output column 27 away from the second electric push cylinder 25 is rotatably connected with the second moving seat 26.

[0054] In order to facilitate the up-and-down movement of the damping frame 16 while it is moving horizontally, the fitting and limiting assembly further includes a horizontal column 28 and an adjusting inclined slot 29. A plurality of horizontal columns 28 are fixedly connected to both sides of the bottom of the adjusting seat 21. A plurality of adjusting inclined slots 29 are formed at positions corresponding to the horizontal columns 28 on both sides of the moving support frame 15. The horizontal column 28 is slidably connected with the adjusting inclined slot 29.

[0055] In order to facilitate driving the moving support frame 15 to move and facilitate its installation, the fitting and limiting assembly further includes a support bottom frame 30 and moving wheels 31. In order to facilitate the third-layer support of the adiabatic tank body 1, the support bottom frame 30 is slidably connected to the inside of the bottom end of the moving support frame 15. A plurality of moving wheels 31 are arranged inside the support bottom frame 30. The end of the moving wheel 31 is rotatably connected with the moving support frame 15.

[0056] In order to facilitate the upward movement of the damping frame 16, the support bottom frame 30 moves upward at the same time to release the limit on the moving wheels 31. The fitting and limiting assembly further includes a reset sleeve 32 and a reset spring 33. A plurality of reset sleeves 32 are fixedly connected to both ends of the moving support frame 15. A reset spring 33 is fixedly connected to the inside of the reset sleeve 32. The bottom end of the reset spring 33 is fixedly connected with the moving support frame 15.

[0057] During operation, the moving wheel 31 is used to push the moving support frame 15 and the connecting seat 7 to the appropriate positions. After connecting the connecting seat 7 to the supporting circular seat 2, the staff simultaneously activates multiple groups of the first electric push cylinders 23 and the second electric push cylinders 25, causing the first electric push cylinder 23 to drive the first output column 24 therein, and the second electric push cylinder 25 to drive the second output column 27 therein to push the shock-absorbing frame 16 and the adjusting seat 21 towards the direction of the adiabatic tank body 1, so that the metal rubber pad 19 on the shock-absorbing frame 16 forms a tightly fitting state with the adiabatic tank body 1. Furthermore, while the adjusting seat 21 is moving, it moves towards the direction of the supporting bottom frame 30 while moving towards the adiabatic tank body 1 through the horizontal column 28 and the adjusting chute 29. Then it drives the supporting bottom frame 30 to move towards the direction of the moving wheel 31, making it contact the ground, thereby providing the third layer of support for the device and the adiabatic tank body 1. After the adiabatic tank body 1 is tightly fitted through the metal rubber pad 19, through the design of multiple groups of resonance springs 20, the low-frequency resonance peak value is offset, further reducing the frequency vibration conducted by the adiabatic tank body 1 during operation, further reducing the vibration peak value transmitted to the supporting structure, improving the overall supporting strength of the supporting structure, and further improving the overall service life and safety of the device during use.

[0058] As Figures 1 to 11 shown, the embodiment of the present invention also provides an installation method for the bottom supporting structure of an adiabatic tank. This installation method for the bottom supporting structure of an adiabatic tank is mainly applicable to the above-mentioned bottom supporting structure of an adiabatic tank, and this installation method mainly includes the following steps:

[0059] S1: First, adjust the adiabatic tank body 1 to the appropriate position and installation height through an external forklift;

[0060] S2: Connect and position the clamping tenon frames 5 on multiple moving support frames 15 with the supporting circular seat 2 on the adiabatic tank body 1, thereby providing a simple support for the adiabatic tank body 1;

[0061] S2: Connect and fix the parts in the positioning clamping assembly to multiple moving support frames 15 and clamping tenon frames 5 to form the first layer of fixed support for the adiabatic tank body 1;

[0062] S4: By simultaneously activating the driving parts in the fitting and limiting assembly, the driving parts drive the shock-absorbing frame 16 and the metal rubber pad 19 to fit the outer shell of the adiabatic tank body 1, so as to achieve the second layer of fitting for the adiabatic tank body 1;

[0063] S5: Furthermore, when the shock-absorbing frame 16 is moving, it drives the supporting bottom frame 30 to fit with the ground, providing the third layer of support and positioning for the installed adiabatic tank body 1, so as to complete the supporting structure for the adiabatic tank body 1.

[0064] The above-mentioned bottom support structure of the adiabatic tank of the present invention and its installation method adopt a triple energy dissipation mechanism to construct a composite support structure. The radially distributed clamping mortise frames 3 and the circumferentially arranged clamping tenon frames 5 form a spatial grid bite, and the clamping mortise grooves 4 and the clamping tenon grooves 6 are matched to form a tenon-mortise bite structure, realizing the dynamic self-tightening effect under vibration conditions. The vibration energy promotes the generation of an incremental normal pressure on the tenon-mortise contact surface, and geometrically dissipates the vibration energy. The connection screw 11 is driven by rotating the threaded sleeve 9 to generate an axial pre-tightening force for mechanical pre-tightening. The connecting arc-shaped piece 8 undergoes elastic deformation under vibration, compensates for the structural gap through the deformation displacement, and converts the contact surface friction effect into vibration kinetic energy for friction damping constraint. The thickness gradient of the metal rubber pad is set to form a stiffness gradient. The resonance spring adopts a non-equidistant spiral design, and the damping sleeve is filled with nano-particle damping material to form a multi-band vibration damping component, absorbing the vibration frequency for elastic resonance cancellation, avoiding the situation that the vibration energy is transmitted to the support structure due to rigid connection, resulting in resonance effect and accelerating the structural damage, effectively solving the problems that the traditional support structure relies on bolt fastening and weld connection and is prone to looseness or fatigue cracking under long-term vibration.
