Embodiment 1

[0028] This embodiment is basically as figure 1 Shown:

[0029] The anti-sway and shock-absorbing structure test model of a large-scale tank includes an outer tank 1, an inner tank 2 and an anti-sway frame 15. The upper end of the outer tank 1 is an arched structure 4 with an opening thereon, and the outer tank 1 is a reinforced concrete structure. The inner tank 2 is cylindrical and has an open upper end. The inner tank 2 is a steel structure and placed at the center of the outer tank 1. The outer tank 1 and the inner tank 2 are filled with a heat insulating material 3, which is pearlite. combine Figure 4 , the upper end of the inner wall of the outer tank 1 is fixedly provided with a suspension frame 17, the center of the suspension frame 17 is aligned with the center of the inner tank 2, the suspension frame 17 is fixedly provided with a steel rope 20, and the inner wall of the outer tank 1 is fixedly provided with a pole 19. There are several limit cylinders 18, and th...

Embodiment 2

[0035] combine Figure 5 , Image 6 , the difference from Embodiment 1 is that the anti-sway frame 15 is composed of several ring-shaped anti-sway plates with different diameters, and several anti-sway plates are all concentric and fixedly connected by the connecting frame 21, the diameter of the innermost anti-sway plate It can be set larger to reduce material cost. The top side wall of the anti-sway frame 15 is provided with a connector 22, and the connector 22 is fixedly connected with the steel rope 20. The anti-sway frame 15 in the present embodiment is not connected with the adjusting rod 5, so the connecting frame 21 is not provided at the outermost end of the anti-sway frame 15. The outermost end of 15 is fixedly provided with connecting frame 21, and connecting frame 21 is fixed with adjusting rod 5 by bolt again. In this embodiment, the fixing method of the steel rope 20 is quite conventional and will not be repeated here.

[0036] In this embodiment, when the li...

Abstract

The invention relates to the technical field of shock isolation and shock absorption, and specifically discloses a large tank body anti-shaking shock absorption structure test model. The large tank body anti-shaking shock absorption structure test model comprises an outer tank, an inner tank and an anti-shaking frame, wherein the upper end of the outer tank is arched, the inner tank is placed in the center of the outer tank, the upper end of the inner tank is open, the space between the outer tank and the inner tank is filled with a thermal insulation material, and the anti-shaking frame is located in the inner tank and can divide liquid on the upper portion of the inner tank into multiple parts; a first guide rail, a second guide rail and a plurality of adjusting mechanisms are arranged on the inner tank; the first guide rail is partially annular and surrounds the inner tank; the second guide rail is partially annular and is arranged on the upper end surface of the inner tank; and each adjusting mechanism comprises an adjusting rod, a first sliding block and a second sliding block, the first sliding block is arranged on the first guide rail in a sliding mode, the second sliding block is arranged on the second guide rail in a sliding mode, and the first sliding block and the second sliding block are fixedly connected with the adjusting rod by means of bolts. The large tank bodyanti-shaking shock absorption structure test model aims to solve the problem of how to reduce the shaking degree of liquid in a large tank body.

Description

technical field [0001] The invention relates to the technical field of shock isolation and shock absorption, and specifically discloses a test model of a large-scale tank anti-sway shock absorbing structure. Background technique [0002] Large-scale tanks are very large in size and can be tens of meters in diameter. These tanks are generally used to contain flammable, explosive, toxic and other liquids, so safety cannot be ignored, especially shock isolation, shock absorption and liquid protection. In terms of structure, it is very important. The seismic isolation structure of the existing large-scale tank is basically as follows: a pile is driven into the ground, a shock isolator is installed on the pile, and the bottom of the tank is connected to the shock isolator. This structure is very simple, and the construction and installation are very convenient and quick. The cost is also low, but it only has a poor shock isolation effect and does not have the function of liquid ...
