Problems solved by technology
The liner of LNG vehicle-mounted gas tank is generally composed of three parts, namely, the inner rear head, the cylinder body, and the inner front head. Then assemble the inner front head and the cylinder body, and after the two heads and the cylinder body are combined, place the gas tank liner in the outer cylinder to carry out the gas tank liner and outer cylinder combination. The current gas tank It is very troublesome and difficult to assemble the bladder and the outer cylinder by manual extrusion and beating, and it is easy to cause certain damage to the two heads and the cylinder.
The tooling cannot be aligned and installed during the lifting process

The invention relates to a large sleeving hoisting assembly for a liquefied gas steel cylinder inner container. The hoisting assembly comprises a main hoisting body, an inner container opening part clamping device arranged on the upper portion of the main hoisting body, and a gas pressure internal compressing structure arranged on the lower portion of the main hoisting body. The gas pressure internal compressing structure comprises a main gas pressure cylinder connecting body arranged on the lower portion of the main hoisting body, pressure measurement abutting devices are symmetrically or circumferentially arranged on the lateral portion of the main gas pressure cylinder connecting body, and a bottom absorption device is arranged on the lower portion of the main gas pressure cylinder connecting body. The hoisting assembly has the advantages that since the liquefied gas steel cylinder inner container is compressed in an internal type compressing mode, the hoisting assembly has the advantages of being high in stability performance, firm in connection, safe in use and the like; meanwhile, the connection perpendicularity performance of the inner container and an external body is excellent, and mounting is accurate in the assembling process.
Description
technical field [0001] The invention relates to the field of manufacturing liquefied steel cylinders, in particular to a large-scale liquefied steel cylinder liner sleeve hoisting. Background technique [0002] Compared with the document application number 201520030909.1, a tool for assembling the inner tank and the outer cylinder of the liquefied natural gas vehicle tank is published, and the liquefied natural gas vehicle fueled by liquefied natural gas has been put into use. The liner of LNG vehicle-mounted gas tank is generally composed of three parts, namely, the inner rear head, the cylinder body, and the inner front head. Then assemble the inner front head and the cylinder body, and after the two heads and the cylinder body are combined, place the gas tank liner in the outer cylinder to carry out the gas tank liner and outer cylinder combination. The current gas tank The combination of the bladder and the outer cylinder is usually squeezed and knocked by hand, which i...
