Description

Technical Field

[0001] This utility model relates to the technical field of experimental benches, specifically a ground operation device for remanufacturing verification of general aviation piston engines. Background Technology

[0002] Piston-type aircraft engines are reciprocating internal combustion engines that provide power for aircraft flight. To improve engine lifespan, they are coated with a friction pair flame-sprayed coating. During wear resistance testing of this coating, the engine must be run on a test bench.

[0003] The existing experimental platform has the following shortcomings: the overall weight and size of the engine body are large, making it inconvenient to install and disassemble. At the same time, it is not convenient to quickly connect the electric motor to the engine, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a ground-based operating device for remanufacturing verification of general aviation piston engines, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ground operating device for a general aviation piston engine used for remanufacturing verification, comprising a support frame, a fixed frame, a control box, and an engine body. The fixed frame is disposed on one side inside the support frame and is fixedly connected to the support frame. A movable frame is mounted on the upper part of the fixed frame via a track. An electric motor and a transmission box connected to the electric motor are disposed on the upper surface of the movable frame. A lifting mechanism is disposed on the upper part of the support frame on the side away from the fixed frame. The control box is disposed on one side inside the support frame. The engine body is mounted and fixed on the inner side of the support frame and is located below the lifting mechanism. The power shaft of the engine body is connected to the output shaft of the transmission box.

[0006] Preferably, the lower ends of the support frame and the fixing frame are provided with a number of support feet.

[0007] Preferably, the lifting mechanism is a manual hoist.

[0008] Preferably, the control box is electrically connected to both the engine body and the electric motor.

[0009] Preferably, the electric motor is mounted on a motor mount on the upper surface of the movable frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting up a support frame with a lifting mechanism and a fixed frame inside the support frame, and a movable frame on the fixed frame via a track, the motor and transmission box are both set on the upper surface of the movable frame, so that the motor and transmission box can move quickly in the axial direction, which facilitates quick connection with the engine body for experiments. Furthermore, the lifting mechanism on the support frame and the channel on the inner side for transporting the engine body greatly facilitate the installation and disassembly of the engine body, thereby improving work efficiency.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a ground operation device for remanufacturing verification of a general aviation piston engine, including a support frame 1, a fixed frame 2, a control box 3, and an engine body 4. The fixed frame 2 is disposed inside the support frame 1 and is fixedly connected to the support frame 1. A movable frame 5 is mounted on the upper part of the fixed frame 2 via a rail. An electric motor 6 and a transmission box 7 connected to the electric motor 6 are disposed on the upper surface of the movable frame 5. A lifting mechanism is disposed above the support frame 1 on the side away from the fixed frame 2. The control box 3 is disposed inside the support frame 1. The engine body 4 is mounted and fixed inside the support frame 1 and is located below the lifting mechanism. The power shaft of the engine body 4 is connected to the output shaft of the transmission box 7.

[0017] The lower ends of both the support frame 1 and the fixing frame 2 are provided with several support feet.

[0018] The lifting mechanism is specifically a manual hoist 8.

[0019] In this embodiment, a channel for transferring the engine body 4 is provided on the inner side of the support frame 1, below the manual hoist 8. The channel is located below the manual hoist 8. In use, the engine body 4 is moved into the channel by rotating the trolley and placed below the manual hoist 8. Then, the height of the engine body 4 is raised by the manual hoist 8, which facilitates the quick installation and disassembly of the engine body 4.

[0020] The control box 3 is electrically connected to the engine body 4 and the electric motor 6.

[0021] The electric motor 6 is mounted on a motor mount on the upper surface of the movable frame 5.

[0022] Specifically, when using this utility model, the engine body 4 is moved to the inside of the support frame 1 and placed below the manual hoist 8. Then, the engine body 4 is raised by the manual hoist 8 until the engine body 4, the motor 6, and the transmission box 7 are on the same horizontal plane. The engine body 4 is then fixed to the inner wall of the support frame 4. At this time, the moving frame 5 drives the motor 6 and the transmission box 7 to move synchronously toward the engine body 4. The transmission box 7 is then connected to the engine body 4. Finally, the control box 3 controls the motor 6 to work, and the motor 6 drives the engine body 4 to run on the ground through the transmission box 7, thereby conducting a wear resistance test on the flame coating of the internal friction pair of the engine body 4.
