Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A fuselage jacking and weighing device comprises a jacking and weighing structure body 1, three triangular support frames 4 are fixedly connected to the lower end outer surface of the jacking and weighing structure body 1, a first universal roller 5, a second universal roller 8, and a third universal roller 9 are arranged on the lower end outer surface of the triangular support frame 4, a hydraulic lifting rod 3 is fixedly connected to the upper end outer surface of the triangular support frame 4, a hydraulic structure body 2 is arranged on the left outer surface of the hydraulic lifting rod 3, an oil pipe 7 is fixedly connected between the hydraulic lifting rod 3 and the hydraulic structure body 2, a hydraulic operating rod 10 is fixedly connected to the upper end outer surface of the hydraulic structure body 2, and a telescopic end 6 is movably connected to the upper end outer surface of the hydraulic lifting rod 3;

[0023] Firstly, the lifting and weighing structure body 1 is stably placed under the fuselage of the aircraft that needs to be lifted and weighed through the three triangular support frames 4 at its lower end. The design of the triangular support frames 4 ensures the stability of the device when bearing the weight of the fuselage, and at the same time provides sufficient support area to disperse the pressure. On the outer surface of the lower end of each triangular support frame 4, a first universal roller 5, a second universal roller 8 and a third universal roller 9 are respectively arranged. These universal rollers not only allow the lifting and weighing structure body 1 to move freely on the plane to facilitate positioning it in the correct position, but also provide additional stability during the lifting process to prevent the device from slipping or deflecting during lifting. On the outer surface of the upper end of the triangular support frame 4, a hydraulic lifting rod 3 is fixedly connected. The hydraulic lifting rod 3 is one of the core components of the lifting and weighing structure body 1, and it is responsible for vertically lifting the fuselage to the required height. The left outer surface of the hydraulic lifting rod 3 is provided with a hydraulic structure The main body 2 and the hydraulic structure main body 2 are connected to the hydraulic lifting rod 3 through the oil pipe 7 to provide a power source for it. The outer surface of the upper end of the hydraulic structure main body 2 is fixedly connected with a hydraulic operating rod 10. The operator can control the working state of the hydraulic structure main body 2 through the hydraulic operating rod 10, and then control the lifting speed and height of the hydraulic lifting rod 3. When it is necessary to lift the fuselage, the operator sends an instruction to the hydraulic structure main body 2 through the hydraulic operating rod 10. The hydraulic structure main body 2 transports hydraulic oil to the hydraulic lifting rod 3 through the oil pipe 7, driving the telescopic end 6 of the hydraulic lifting rod 3 to extend upward, thereby lifting the fuselage to the required height. During the lifting process, a stable supporting relationship is formed between the telescopic end 6 of the hydraulic lifting rod 3 and the fuselage, ensuring the stability and safety of the fuselage during the lifting process. At the same time, the design of the hydraulic lifting rod 3 also takes into account the weighing function, and the weight of the fuselage can be accurately calculated by measuring the pressure change of the hydraulic oil.

[0024] The jacking and weighing structure body 1 includes an upper fixing part, an intermediate connecting part, and a lower fixing part. The front end outer surface of the jacking and weighing structure body 1 is provided with an arc-shaped installation groove adapted to the hydraulic lifting rod 3. The jacking and weighing structure body 1 is fixedly connected to the hydraulic lifting rod 3 through the arc-shaped installation groove. The upper end outer surface of the hydraulic lifting rod 3 is provided with a circular through hole adapted to the telescopic end 6. The hydraulic lifting rod 3 is movably connected to the telescopic end 6 through the circular through hole. There are three hydraulic lifting rods 3, which are respectively arranged at the three corners of the jacking and weighing structure body 1.

[0025] First of all, the jacking and weighing structure body 1 is composed of an upper fixing part, an intermediate connecting part and a lower fixing part, which together constitute a stable structural frame. This layered design not only enhances the structural strength, but also facilitates the installation and maintenance of each component. An arc-shaped mounting groove compatible with the hydraulic lifting rod 3 is provided on the front end outer surface of the jacking and weighing structure body 1. The design of these arc-shaped mounting grooves enables the hydraulic lifting rod 3 to be firmly fixed on the jacking and weighing structure body 1, thereby ensuring stability during the jacking process. A circular through hole compatible with the telescopic end 6 is provided on the upper end outer surface of each hydraulic lifting rod 3. Through this circular through hole, the telescopic end 6 can move up and down inside the hydraulic lifting rod 3, thereby realizing the jacking of the fuselage. Due to the movable connection design between the telescopic end 6 and the hydraulic lifting rod 3, the flexibility and stability of the telescopic end 6 during the lifting process can be ensured. At the corners, three hydraulic lifting rods 3 are respectively arranged. This layout design can ensure that the fuselage is subjected to uniform force during the jacking process and prevent the fuselage from tilting or deforming. At the same time, the three hydraulic lifting rods 3 can also be independently controlled to adjust the height and position of the fuselage according to actual needs. During the jacking process, the operator controls the hydraulic structure body 2 (which is not explicitly mentioned in the description, but its existence can be inferred from the context) to supply hydraulic oil to the hydraulic lifting rod 3. The pressure of the hydraulic oil causes the telescopic end 6 to extend upward, thereby pushing the fuselage to move upward. Due to the number and layout design of the hydraulic lifting rods 3, the fuselage can be smoothly lifted to the required height and maintain a stable posture. After the jacking is completed, a stable supporting relationship is formed between the telescopic end 6 and the fuselage, ensuring the stability and safety of the fuselage during the weighing process. At the same time, the design of the hydraulic lifting rod 3 also takes into account the weighing function, and the weight of the fuselage can be accurately calculated by measuring the pressure change of the hydraulic oil.
