Background
Helium is a gas having desirable gas characteristics, and at normal temperature, helium is an extremely light colorless, odorless, tasteless monoatomic gas. When the temperature after liquefaction is reduced to 2.174K, the liquid helium has the special properties of small surface tension, strong thermal conductivity, extremely low viscosity and the like, and the liquid helium can obtain low temperature close to absolute zero. Helium is a very important rare strategic resource, global supply is tense, the demand of domestic helium is increasingly large along with the development of science and technology in recent years, and the helium is widely applied to various fields of aerospace, automobile transportation, diving, medical treatment and health and the like.
Helium is typically contained in high pressure cylinders and the cylinder is gray in color and marked with a green "helium" letter. The filling of gaseous helium should be carried out according to the national standard GB14194, which is dangerous for packaging and storage in china, which is classified as a storage and transportation hazard: type 2.2 nonflammable gas, chinese dangerous goods packaging mark: 5. because of the specificity of helium, helium has certain difficulty in storage and transportation, wherein long-tube truck helium, tube bundle truck helium and tank truck helium are three common storage and transportation modes. Wherein, the tube bundle vehicle is usually used for transporting helium gas by filling helium gas cylinders and then fixing the helium gas cylinders on a vehicle. Since helium cylinders are filled with high pressure gas, there is a risk of explosion, they must be secured against damage from external shock or vibration during the travel of the tube bundle.
The prior operation is to orderly stack helium gas cylinders in a carriage, and then integrally fix the stacked helium gas cylinders through ropes or fixing frames. However, such loading makes it difficult for the operator to access the gas cylinder from the operator's location, and thus to install and remove the helium cylinder in the correct, proper location. Based on this problem, the prior patent (publication No. KR20130026824 a) discloses a gas cylinder fixing device for a field verification vehicle, specifically, including a first rotary disk having a first support portion that receives and supports a rear end of each gas cylinder, a second rotary disk having a second support portion that is rotatably mounted on an upper surface of a base frame through a rotary shaft so that a plurality of gas cylinders can be mounted and dismounted at positions corresponding thereto. The second rotary disk is arranged opposite to the first rotary disk and rotates together with the first rotary disk, and is provided with a second supporting part for accommodating and supporting the front end of each gas cylinder; a plurality of cylinder support plates are radially installed between the second rotary disk and the second rotary disk to support the outer peripheral surface of each cylinder, and the cylinder support plates and their adjacent cylinder support plates are provided with fixing bands around the outer surfaces of the cylinders.
The gas cylinder fixing device can rotate the gas cylinder to be replaced to a position close to an operator through the first rotary disk and the second rotary disk during the work of replacing the gas cylinder, so that the operator can detach the gas cylinder more easily, and the convenience, safety and working efficiency of the disassembly and assembly of the gas cylinder can be improved. However, the pressure of the gas cylinder may change in the actual transportation process, the gas cylinder fixing device cannot detect the gas tightness of the gas cylinder, the gas cylinder can be detached and detected through special leakage detection equipment after the gas cylinder is stopped, and if the gas cylinder cannot be detected in time, the gas is wasted, and on the other hand, the transportation of the gas cylinder is easy to have a great potential safety hazard.
