[0021] The positioning clamping assembly is arranged at the end of each clamping tenon frame 5 away from the supporting round seat 2. The positioning clamping assembly is used in conjunction with the insulating tank body 1 and the supporting round seat 2, thereby facilitating the first layer of simple support for the insulating tank body 1 through the positioning clamping assembly.

[0022] The fitting and limiting component is connected to the positioning clamping component and the insulated tank body 1. The fitting and limiting component includes a plurality of vibration-damping modules distributed circumferentially along the outer side of the bottom of the insulated tank body 1. Each vibration-damping module is connected to the corresponding clamping tenon frame 5 through a linkage mechanism. The vibration-damping module includes a contact portion elastically fitted with the outer wall of the insulated tank body 1. It is used in conjunction with the positioning clamping component and the insulated tank body 1, and then the second layer of fitting support for the insulated tank body 1 is conveniently provided through the limiting component.

[0023] During operation, when the insulated tank body 1 needs to be installed and used, after adjusting the insulated tank body 1 to a suitable position and installation height by an external forklift, the staff uses multiple snap-in tenons 5 to support the snap-in tenons 3 and the snap-in tenon grooves 4 on the round seat 2 as mortise and tenon interfaces and snap-in them on the supporting round seat 2 in sequence. Under vibration conditions, the snap-in nodes can dissipate friction energy between the snap-in joints and the connections to reduce the resonance effect, thereby completing simple support for the insulated tank body 1.

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.

[0025] 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.

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.

The inner side of the first electric push cylinder 23 is provided with a first output column 24, and the telescopic end of the first output column 24 is rotatably connected to the first movable seat 22.

[0030] The linkage mechanism of the fitting limit assembly also includes a second electric push cylinder 25, a second movable seat 26 and a second output column 27. The top end of the adjustment seat 21 away from the snap-in tenon frame 5 is fixedly connected to the second movable seat 26.

The inner side of the second electric push cylinder 25 is provided with a second output column 27. The second output column 27 is rotatably connected to the second movable seat 26 at the end away from the second electric push cylinder 25.

[0031] In order to facilitate the vibration damping frame 16 to move up and down at the same time when it moves horizontally, the fitting limit assembly also includes a transverse column 28 and an adjustment bevel 29. Both sides of the bottom of the adjustment seat 21 are fixedly connected with multiple transverse columns 28, and both sides of the movable support frame 15 and corresponding to the transverse columns 28 are provided with multiple adjustment bevels 29.

[0035] like Figures 1 to 11 As shown, an embodiment of the present invention further provides a method for installing a bottom support structure of an insulated tank. The method for installing a bottom support structure of an insulated tank is mainly applicable to the above-mentioned bottom support structure of an insulated tank. The method for installing a bottom support structure of an insulated tank mainly includes the following steps: S1: First, the insulation tank body 1 is adjusted to a suitable position and installation height by an external forklift; S2: Connect and position the clamping tenon frames 5 on the plurality of movable support frames 15 with the supporting round seats 2 on the thermal insulation tank body 1, so as to provide simple support for the thermal insulation tank body 1; S2: Connect and fix the parts in the positioning clamping assembly to the multiple movable support frames 15 and the clamping tenon frame 5 to form a first layer of fixed support for the insulation tank body 1; S4: by simultaneously starting the driving member in the laminating limit assembly, the driving member drives the vibration damping frame 16 and the metal rubber pad 19 to laminate the outer shell of the thermal insulation tank body 1, so as to laminate the second layer of the thermal insulation tank body 1; S5: When the vibration-damping frame 16 moves, it drives the supporting base frame 30 to fit into the ground, and performs the third-layer support positioning on the installed insulated tank body 1, so as to complete the supporting structure of the insulated tank body 1.

[0036] The above-mentioned insulating tank bottom support structure and installation method of the present invention adopt a triple energy dissipation mechanism to construct a composite support structure, and form a spatial grid engagement through radially distributed snap-in mortise frames 3 and circumferentially arranged snap-in tenon frames 5, and form a tenon-tenon engagement structure by using snap-in mortise grooves 4 and snap-in tenon grooves 6 to achieve a dynamic self-tightening effect under vibration conditions. The vibration energy causes the mortise-tenon contact surface to generate a normal pressure increment, and the vibration energy is geometrically dissipated. The axial pre-tightening force is generated by rotating the threaded sleeve 9 to drive the connecting screw 11 to perform mechanical pre-tightening, and the arc-shaped piece 8 is elastically deformed under vibration. The structural gap is compensated by deformation displacement, and the friction effect of the contact surface is converted into vibration kinetic energy for friction damping constraint. The thickness gradient of the metal rubber pad is set to form a stiffness gradient. The resonant spring adopts a non-equidistant spiral design, and the vibration-damping sleeve is filled with nanoparticle damping material to form a multi-band vibration-damping component. The vibration frequency is absorbed for elastic resonance offset, which prevents the vibration energy from being transmitted to the supporting structure due to the rigid connection, forming a resonance effect and accelerating structural damage. This effectively solves the problem that traditional supporting structures rely on bolt fastening and weld connections, which are prone to loosening or fatigue cracking under long-term vibration.
