[0028] Examples:
[0029] In the following, with reference to the accompanying drawings, the present invention will be further explained by taking the new LNG railway tank car tank body assembly process method as an example, but it is not limited to the vehicle type and the tank body structure.
[0030] Technical requirements: The minimum distance between the inner and outer tanks is about 20mm; the outer tank cannot touch the insulating material laid on the outer surface of the inner tank during the assembly process, causing damage to the insulating material; the inner and outer tank axes are not offset Larger than 5mm; the interlayer has no contact after the inside and outside are integrated, and the whole is sealed.
[0031] a. Drop the outer tank cylinder 1 onto the roller support device to adjust the positioning; fix the inner tank on the chute type adjustment and detection device through a flange at one end, and fix the other end on the end support device. At this time, the li...
