Problems solved by technology

[0003] At present, most of the larger airports use the ground well pipe network refueling mode. When refueling, a refueling joint that connects the ground well pipe network interface with the aircraft refueling port is needed. At present, most airports use manual handling of the refueling joint. Firstly, the refueling joint is transported to the refueling interface of the underground well pipe network through mechanical equipment, and then the refueling joint is moved by manpower and the position of the refueling joint is adjusted up and down, so that the refueling joint can be connected with the refueling interface of the underground well pipe network. The refueling joint facilities used are heavy, and currently only rely on manpower to move and adjust the position of the refueling joint. The biggest hidden danger of this method is that the personal safety of the workers cannot be guaranteed. In addition, this method is due to manual handling and adjustment of the refueling joint. position, so that the refueling connector is connected to the refueling connector in the ground well pipe network, which makes the efficiency of refueling the aircraft even lower

[0004] At present, gas springs are used to lift the refueling connector, and then the refueling connector is lifted. The basic principle is to drive the refueling connector to move vertically through the expansion and contraction of the gas spring, but this method cannot be well realized. The main reasons for connecting the refueling joint with the ground well pipe network interface are as follows:

[0005] 1. The gas spring is driving the refueling connector to dock with the underground well refueling interface. When the refueling connector and the underground well refueling interface are close to the docking state, the gas spring will be in a compressed state in most cases at this time. At this time, it still needs to be moved again manually. refueling joint, so that the refueling joint can be completely docked with the refueling interface of the well pipe network, but at this time the gas spring is in a compressed state, and the gas spring generates a push force on the refueling joint, and the operator not only needs to overcome during the process of moving the refueling joint The self-weight of the refueling connector and the need to overcome the push force generated by the gas spring on the refueling connector make the process of connecting the counterparts more troublesome and increase the difficulty of the operator's work

[0006] 2. Gas springs have strict requirements on the operating environment. Outdoor operating environments often shorten the service life of gas springs, thereby increasing operating costs. In addition, gas springs can only be adapted to connect the refueling connector with the refueling connector of the well pipe network with a small depth. The scope is greatly limited, and it is impossible to carry out large-scale promotion and application
