The first hydraulic push rods 5 can effectively adjust the height of the adapter seat 1, so as to facilitate the use of maintenance personnel with different heights.

[0026] Example 2

[0027] like Figure 1-3 As shown, a rotating roller 21 is installed inside the arc groove 2, and a rotating motor 22 is installed on the right side of the rotating roller 21 and inside the adapter 1. One end of the rotating roller 21 is rotatably connected to the arc groove 2, and the other end of the rotating roller 21 is bolted to the output end of the rotating motor 22. The rotating motor 22 is a servo motor that can effectively control the speed, thereby ensuring the speed when inspecting the tire.

[0028] The bottom of the clamping plate 3 is symmetrically fixed with a screw slider 31, and a linear guide rail 32 is opened on the periphery of the screw slider 31, and a screw 33 passes through the screw slider 31 inside the linear guide rail 32 and intersects with the thread of the screw slider 31.

[0029] A driven gear 34 is installed inside the adapter seat 1 and at one end of the lead screw 33 that passes through the linear guide 32 and is located inside the adapter seat 1, and a driving gear 35 is meshed with the driven gear 34, and a driving motor 36 is fixedly connected to the driving gear 35. The lead screw 33 driven by the driving motor 36 are positive and negative lead screws, and the driving motor 36 can effectively provide power for the rotation of the lead screw 33.

[0030] A connection pad 51 is installed at the connection between the top of the first hydraulic push rod 5 and the bottom of the adapter 1, and a base 52 is installed on the periphery of the first hydraulic push rod 5. The connection pad 51 can effectively ensure the stability of the connection.

[0031] The base 52 extends from the inside to the bottom corners, where second hydraulic push rods 53 are installed. Support feet 54 are installed at the bottom of the second hydraulic push rods 53, and universal wheels 55 are installed on the inner side of the second hydraulic push rods 53 to facilitate the movement of the equipment.

[0032] The working process of the utility model is as follows: when using an aircraft maintenance adapter to perform aircraft tire maintenance and inspection, first, the equipment is moved to the bottom of the tire through the universal wheel 55, and then, the second hydraulic push rod 53 is controlled to move downward, driving the supporting foot 54 for support, so that the universal wheel 55 is separated from the ground to ensure the stability of the equipment, and then, the first hydraulic push rod 5 is controlled to drive the adapter seat 1 to move upward, so that the aircraft tire is located inside the arc groove 2. After completion, first, the rotating motor 22 is used to drive the rotating roller 21 to rotate, so that the rotating roller 21 drives the aircraft tire to rotate, which is convenient for the staff to check. If a problem is found and needs to be repaired, only the side with the problem needs to be turned upward, and then the driving motor 36 is controlled to drive the active gear 35 to rotate, and the active gear 35 drives the driven gear 34 to rotate, thereby driving the screw rod 33 to rotate in the linear guide rail 32, so that the screw rod slider 31 drives the clamping plate 3 to clamp the lower end of the aircraft tire, and then the maintenance can be started. The utility model can effectively clamp the aircraft tire through design when the adapter is used to perform maintenance and inspection on the aircraft tire, and the clamping effect is good.
