Abstract
An inner container rear support of a horizontal-typed vehicle-mounted liquefied natural gas storage tank relates to the mechanical technique field of the pressure vessel. The inner container rear support of the horizontal-typed vehicle-mounted liquefied natural gas storage tank utilizes the key technology that a nonmetal composite supporting pipe is arranged between an inner container and an outer casing. An external end section of an inner container rear support sleeve is weld with a central hole of an inner container rear head in a plug-in mode, an inner end of the inner container rear support sleeve is weld with a rear support of the inner container, an external end of the rear support is weld with a rear head of an external container; an inner end section of the composite supporting pipe is fixedly connected with the rear support sleeve of the inner container through a dowel, and an external end section of the composite supporting pipe is flexibly connected with the rear support in a sliding plug-in mode. The inner container rear support of the horizontal-typed vehicle-mounted liquefied natural gas storage tank is used for fixing the inner container and the outer casing of the storage tank. The inner container rear support of the horizontal-typed vehicle-mounted liquefied natural gas storage tank has the advantages of being good in fixing effect, avoiding the damage of rear supporting assembly from the axial deformation of inner container tank body and reducing the heat loss effectively.
