[0002] In petrochemical industry, logistics and warehousing industry, crane pipe truck loading system is the key equipment for realizing the efficient and safe transportation of liquid or gas from storage tank or pipeline to truck tank. Crane pipe truck loading system is usually composed of multiple pipeline sections and joints, and the vertical pipe is an important component directly connected with the tank opening of tank truck, and its posture stability directly affects the loading efficiency and safety.

[0003] However, the existing crane pipe truck loading system has some deficiencies in vertical pipe posture maintaining:

[0004] Unstable vertical pipe posture: the traditional crane pipe vertical pipe part mainly relies on its own gravity to keep drooping, so as to maintain vertical state with ground. But with the increase of use time, pipeline aging, connection wear and tear, movable flange jam and other problems will cause the vertical pipe to gradually deviate from the vertical state. The inclination of vertical pipe will increase the collision and friction with the tank opening of tank truck, reduce the loading efficiency, and even may cause leakage and other safety accidents.

[0005] Lack of adjustability: the existing vertical pipe posture maintaining device does not have good adjustability. When there is deviation on site, such as slight change of tank opening position of tank truck or installation error of crane pipe itself, the vertical pipe posture cannot be adjusted in time to keep ideal vertical state. This limits the adaptability and flexibility of crane pipe truck loading system in different loading scenarios.
