Problems solved by technology
In the existing technology, pull rods, compression rods, V-shaped slings, radial pad support devices or combined axial and radial support devices are used. Among them, the inner support devices of pull rods, compression rods, and V-shaped slings are complex and difficult to install. Inconvenient, the support strength of the radial pad support device is reliable, but the heat transfer is relatively large, the structure of the combined axial and radial support device is complicated, the installation is inconvenient, and special installation holes are required to be opened on the outer tank body, etc.

The invention discloses an axial support device of a liquefied natural gas horizontal tank. The axial support device comprises an outer tank body and an inner tank body arranged in the outer tank body; a fixed support component and a sliding support component are arranged between the inner tank body and the outer tank body, and are symmetrically distributed; the fixed support component includes a fixed outer support ring fixed on the inner side surface of the outer tank body, a first inner support ring fixed on the outer side surface of the inner tank body, and a fixed support pin; the first inner support ring is sleeved in the fixed outer support ring through the fixed support pin; the sliding support component includes a sliding outer support ring fixed on the inner side surface of the outer tank body, a second inner support ring fixed on the outer side surface of the inner tank body, and a sliding support pin; the second inner support ring is sleeved in the sliding outer support ring through the sliding support pin; and the sliding support pin and the sliding outer support ring are slidingly connected. The axial support device is simple in structure, low in heat transfer quantity and convenient for installation, reduces external heat absorbed in the tank, and reduces the loss of liquefied natural gas.
Description
technical field [0001] The invention relates to the technical field of natural gas storage and storage, in particular to an axial support device for a liquefied natural gas horizontal storage tank. Background technique [0002] In the field of low-temperature technology for natural gas storage and machinery manufacturing, the vacuum multi-layer thermal insulating LNG horizontal storage tank is divided into an inner tank and an outer tank. The inner tank is connected to the outer tank through a supporting device. The supporting device must have Sufficient strength to bear the weight of the inner tank and the loaded medium, and at the same time, it is required to minimize the leakage of heat through the inner support device, especially for mobile LNG horizontal storage tanks, the support device must have sufficient strength to withstand the moving process. Impact load. [0003] Under normal pressure, the temperature of LNG is about -162°C, so the LNG storage tank is required ...
