Abstract

The invention discloses a vehicle-mounted LNG (liquefied natural gas) cylinder liner and outer cylinder sleeving device, which relates to the field of installation equipment and methods of vehicle-mounted gas cylinders. The vehicle-mounted LNG cylinder liner and outer cylinder sleeving device comprises a liner (1), a liner feeding device (2), an outer cylinder (3), an outer cylinder feeding device (4), an upper end socket (5), a lower end socket (6) and a clamping holding device (7), wherein the liner (1) is arranged on the liner feeding device (2), the outer cylinder (3) is arranged on the outer cylinder feeding device (4), and the clamping holding device (7) is used for clamping and holding the parts. The vehicle-mounted LNG cylinder liner and outer cylinder sleeving device is characterized in that a nylon material is embedded into the inner side of the clamping holding device (7), and the liner feeding device (2) and the outer cylinder feeding device (4) are respectively and additionally provided with two sets of semicircular guide post guide sleeves with wedged end surfaces. The vehicle-mounted LNG cylinder liner and outer cylinder sleeving device provided by the invention has the advantages that the perpendicularity of the liner can be guaranteed in the vertical hoisting of the liner under a self-supporting effect, and the sleeving is not damaged under a small gap between the liner and the outer cylinder.

Description

technical field

[0001] The invention relates to the field of vehicle-mounted gas cylinder equipment, in particular to the field of installation of vehicle-mounted gas cylinders. Background technique

[0002] As a high-quality, efficient and clean energy, natural gas has received more and more attention in my country, especially the implementation of the "West-to-East Gas Pipeline" project, which provides a rare historical opportunity for the development of natural gas. At present, liquefied natural gas (LNG) cylinders for automobiles have been widely used in China, mainly for buses, taxis, transport trucks and other vehicles. It is expected to continue to increase in the future. With the widespread use of vehicle-mounted gas cylinders, the safety and production capacity of vehicle-mounted gas cylinders have attracted more and more attention.

[0003] At present, the assembly of the inner tank and outer cylinder of domestic LNG vehicle-mounted gas cylinders is generally don...
