[0002] Aircraft engines are highly complex and precise thermodynamic machines. As the heart of an aircraft, they not only power flight but also serve as a vital driving force for the development of aviation. Every major transformation in the history of human aviation has been inseparable from the technological advancements in aircraft engines. After more than a century of development, aircraft engines have become highly reliable and mature products. The aircraft engines currently in use include various types such as turbojet / turbofan engines, turboshaft / turboprop engines, ramjet engines, and piston engines.

[0003] Aircraft engines have numerous parts, most of which are large and heavy. Therefore, during maintenance, the engine needs to be lifted. However, the parts of an aircraft engine are distributed around the engine. During maintenance, the parts need to be inspected, which requires frequent rotation of the aircraft engine to adjust the parts to the appropriate angles for maintenance personnel to perform maintenance. However, existing aircraft engine maintenance racks require the aircraft engine to be lowered, and the rotation angle of the aircraft engine needs to be adjusted by hoisting equipment and manual labor, which is extremely inconvenient.

[0022] The drive assembly 3 includes a fixed bearing 31, a bidirectional threaded rod 32, a nut seat 33, and a turntable 34. A mounting groove is provided on the base plate 1, which is set along the length of the base plate 1 and passes through the surface of the base plate 1 and two opposite side walls. The fixed bearing 31 is connected to the base plate 1, and there is one fixed bearing 31 at each end of the mounting groove. The bidirectional threaded rod 32 is connected between the two fixed bearings 31. The nut seat 33 is connected to the bidirectional threaded rod 32, and there are two symmetrically arranged nut seats 33 on the bidirectional threaded rod 32. The nut seats 33 are cubic in shape, and the side walls of the nut seats 33 slide against the inner wall of the mounting groove. The nut seats 33 are connected to the movable plate 2. The turntable 34 is connected to the end of the bidirectional threaded rod 32 that passes through the fixed bearing 31.

[0023] A guide rail 11 is connected to the base plate 1. The guide rail 11 is set along the length of the base plate 1 and is located below the movable plate 2. A guide rail 11 is provided on each of the opposite sides of the movable plate 2. A slider 21 is connected to the movable plate 2 and is slidably locked on the guide rail 11. By setting the guide rail 11 and the slider 21, the stability of the movable plate 2 during the movement is improved.

[0024] A groove is provided on the top of the fixed frame 4, and a connecting bearing 51 is connected to the roller shaft of the support roller 5. The connecting bearing 51 is connected to the groove.

[0025] The rotating assembly 6 includes a driving pulley 61, a driven pulley 62, a track 63, a fixed plate 64, and a drive motor 65.

[0028] The implementation principle of a clamping bracket for aircraft engine maintenance according to an embodiment of this application is as follows: During operation, the maintenance personnel first rotate the bidirectional threaded rod 32 through the turntable 34 according to the length of the aircraft engine. Since the nut seat 33 cannot rotate in the mounting groove, it can move along the length direction of the bidirectional threaded rod 32. The two nut seats 33 can move closer or further away from each other, thereby driving the two movable plates 2 and the support rollers 5 on the movable plates 2 to move closer or further away from each other, so that the distance between the support rollers 5 on the two movable plates 2 is adapted to the aircraft engine. Then, the maintenance personnel use the hoisting equipment to place the aircraft engine on the support rollers 5 of the two movable plates 2. When it is necessary to rotate the aircraft engine, the drive motor 65 is used to drive the drive pulley 61 to rotate. Through the joint cooperation between the drive pulley 61, the driven pulley 62 and the belt, the support rollers 5 are driven to rotate, and the support rollers 5 drive the heavy aircraft engine to rotate.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model.
