[0002] As we all know, gas refers to natural gas or other mixtures containing combustible gases such as methane. In general, gas usually refers to natural gas, which is mainly composed of methane and is a common clean fuel that is widely used in households, industries, and transportation. Gas can be used for cooking, heating, power generation, and as a fuel for vehicles, etc. However, gas leakage may cause fire or explosion, so various tests will be carried out on the gas to ensure safety and gas production quality. At present, gas detection is mostly completed by loading the gas into a coal sample tank and transporting it to the detection equipment. After placing the coal sample tank, the outlet of the coal sample tank and the inlet of the detection equipment need to be connected for detection. However, the existing lifting structure only lifts the coal sample tank, and the coal sample tank is prone to shaking during the lifting process, thereby affecting the docking of the coal sample tank outlet and the detection equipment inlet, causing position deviation and docking failure. Therefore, it is necessary to design a lifting structure for gas detection equipment to solve the above problems. Utility Model Content
