[0002] A wing jack is an essential device for lifting wings during aircraft maintenance work. It is suitable for multiple scenarios such as aircraft horizontal testing, landing gear retraction and extension testing, wheel replacement, and target calibration. The current wing jack is mainly adjusted by manually pulling a roller arranged at the bottom of a supporting tripod. The adjustment accuracy is low, and it is easy for the actuator to fail to align with the groove on the wing. For example, a Chinese utility model patent with authorization announcement number CN212222293U, entitled "An aircraft synchronous lifting electro-hydraulic jack system", discloses: a control system (101), at least two sets of electric wing jack assemblies (102) and an electric tail jack.

In the technical solution of this utility model, the position of the caster (1) is adjusted by manually pulling the towing rod (2). Therefore, the accuracy of position adjustment is very low. When there is a certain deviation between the jacking cylinder (5) and the wing groove, manual fine adjustment still needs to be continuously performed through the caster (1), which is time-consuming and laborious and inconvenient to operate.

The mounting ring 61 is sleeved on the ejector rod 51 located below the hemispherical structure. In this application, the lifting member is disposed on the floating frame through the mounting frame, and the hemispherical structure at the top end of the ejector rod is matched with the inner wall of the top end of the mounting frame, so that the ejector rod can rotate within a small range in the mounting frame. Therefore, when the lifting member makes an elongation movement to move the floating frame away from the ground, the lifting member can adapt to the rough ground environment, ensuring that the overall structure is more stable. In this application, for the convenience of implementing the above solution, the ejector rod is designed as a two-section structure connected by threads. That is, first, one section of the ejector rod with a hemispherical structure is sleeved in the mounting ring, then the mounting ring is fixedly installed on the mounting frame, and then this section is screwed onto the other section of the ejector rod to achieve assembly.

[0051] See Figure 1 、 3 As shown in FIGS. 4 to 5, the lifting member 5 is a double-acting single-piston rod hydraulic cylinder. In this application, the piston rod of the double-acting single-piston rod hydraulic cylinder is the above-mentioned ejector rod. In another embodiment of this application, it includes but is not limited to using a motor and a matched screw rod and nut sleeve to achieve the function of the lifting member. For example, the motor drives the screw rod to rotate, so that the screw rod moves back and forth in the nut sleeve (the bottom edge of the nut sleeve turns outwards to form a grounding foot to support on the ground. When the screw rod rotates, due to the friction between the grounding foot and the ground, the distance between the nut sleeve and the screw rod changes to jack up the support frame assembly).

[0052] See Figure 1 、 2As shown, a light aligner J is provided at the top of the actuator 3. In the present application, in order to further improve the alignment accuracy and enable the operator to intuitively see whether the actuator is aligned with the groove on the wing, a light aligner is provided at the top of the actuator for alignment. Preferably, the light aligner can be an infrared aligner or a laser aligner.

[0053] See also Figure 1 , 8 As shown, the control box 7 is connected to the plane two-dimensional fine-tuning mechanism 43, and the control box 7 is arranged on the fixed frame 42. Preferably, the control box 7 is electrically connected to the plane two-dimensional fine-tuning mechanism 43. Preferably, the control box 7 is installed on the fixed frame 42 through a stand 71, and the control box 7 controls the motor 431 in the lead screw pair K, thereby intelligently controlling the position fine-tuning of the support frame assembly 1.

[0054] See also Figure 1 , 2 As shown, the wheel shaft assembly 2 is also included. The wheel shaft assembly 2 is arranged at the bottom of the support frame assembly 1 and drives the support frame assembly 1 to move. The wheel shaft assembly 2 includes a follower wheel pair 21. The follower wheel pair 21 includes an eccentric wheel shaft 211 and follower wheels 212 arranged at both ends of the eccentric wheel shaft 211. The eccentric wheel shaft 211 is rotatably connected to the bottom of the inclined support column 11. An operating handle 213 is installed on the eccentric wheel shaft 211. In the present application, in order to save material costs, an eccentric wheel shaft can be used to replace at least one of the above-mentioned pull rods. Preferably, the eccentric wheel shaft 211 is connected to the bottom of the inclined support column 11 in an axially fixed and rotatable manner. The eccentric wheel shaft 211 is rotated circumferentially by the operating handle 213, so that the follower wheels 212 located at both ends of the eccentric wheel shaft 211 are close to the ground or off the ground.

[0055] See also Figure 1 , 2 As shown, the axle assembly 2 also includes a driving wheel group 22, which includes a driving wheel 221, a transverse axis 222, a fork frame 223, a steering handle 224, a suspension beam 225 and a cylinder 226. The steering handle 224 is connected to the transverse axis 222 through the fork frame 223 to control the rolling direction of the driving wheel 221, the suspension beam 225 is connected to the fork frame 223, and the cylinder 226 controls the lifting or falling angle of the suspension beam 225 to control the lifting or falling of the driving wheel 221. In the present application, in order to facilitate management and control, an oil cylinder is used to control the lifting or lowering of the driving wheel (for example, a pneumatic cylinder is no longer used, but a cylinder filled with hydraulic oil is used considering that the lifting parts and the actuator are driven by hydraulic oil). When the driving wheel group 22 and the follower wheel pair 21 are both off the ground, the coarse adjustment of the position of the wing jack device is completed, and the position fine adjustment stage begins. When the driving wheel group 22 and the follower wheel pair 21 are on the ground, the overall structure of the wing jack device can be driven to move.

[0056] See Figure 1 and 2 As shown, it further includes a hydraulic oil storage tank 8 which is arranged on the inclined strut 11. The hydraulic oil storage tank 8 is respectively connected to the actuating cylinder 3 and the jacking member 5 through the inclined strut 11. Preferably, for the convenience of management and control, the hydraulic oil storage tank 8 also supplies oil to the oil cylinder 226.
