Description

Technical Field

[0001] The invention relates to the technical field of combined drive generator maintenance, in particular to a device for cleaning the interior of a combined drive generator. Background Art

[0002] The combined transmission generator is the main power source of the aircraft. Its structure is as follows: Figure 1 As shown in the figure, the closed lubricating oil cooling circulation system utilizes a continuous cooling system. Due to mechanical wear and high-temperature carbonization of the oil, impurities gradually accumulate in the working fluid during use, affecting product performance. Regular lubricant oil replacement is required for maintenance. Currently, routine flight maintenance lacks dedicated equipment and methods for flushing the system's interior; the system is simply performed manually by dumping the lubricating oil and then refilling it with fresh oil. However, the combined drive generator is a comprehensive electromechanical product with complex internal oil circuits, including multiple plunger pumps, cycloid pumps, gear sets, and other components. It weighs nearly 50 kg and is completely enclosed, making cleaning difficult and ineffective. This is because most impurities adhere to the internal cavities, pipes, and components, preventing them from being removed without external force. Even when the plunger pump is not operating, some used oil remains inside, which also cannot be removed. To meet the requirements of onboard use, a device for cleaning the internal structure of the combined drive generator was designed and developed. Summary of the Invention

[0050] The working principle and use process of the present invention:

[0051] During use, the bracket 48 is placed in front of the cleaning device on a flat surface with ample space. The disassembled combined drive generator 50 is manually placed on the bracket 48 with the lifting hole of the combined drive generator 50 facing upward. The lifting ring 12 is installed, and the transfer hanger is pushed to the position of the combined drive generator 50. The lifting ring 12 on the combined drive generator 50 is inserted into the bottom of the lifting head 11 and the latch is inserted. Next, two operators grasp the two handles of the transfer hanger and lift the transfer hanger with the combined drive generator 50 onto the work surface of the operating table 1. The four second movable rollers 4 are placed into the grooved guide rails 23. To save labor, two extended square tubes 5 are provided, through which the transfer hanger with the combined drive generator 50 can be lifted by the shoulders for transportation. After the transfer hanger with the combined transmission generator 50 is placed in the grooved guide rail 23, the transfer hanger is pushed horizontally so that the connecting flange of the combined transmission generator 50 fits into the connecting flange 14 on the generator drive mechanism. Then, the two connecting flanges are clamped at the same time with the clamp 15, and the locking screws on the clamp 15 are tightened. Next, push the servo motor seat 17 in the direction of the combined transmission generator 50. In the initial stage of pushing, it is necessary to lift the locking pin 20 and then push (in the initial stage, the locking pin 20 is stuck in the limit slot 22 on the rear side of the limit strip 21). The servo motor spline sleeve 19 is opposite to the spline shaft on the combined transmission generator 50. If necessary, the angle of the servo motor spline sleeve 19 can be manually rotated slightly to adjust the angle, and the servo motor spline sleeve 19 is fully pushed into place. The sign of being in place is that the locking pin 20 is stuck in the limit slot 22 on the front side of the limit strip 21; then, respectively connect the two pipe openings of the cleaning pipeline 28 to the oil inlet and outlet of the combined transmission generator 50, and open the two ball valves 33.

[0052] After completing the above connection process, the oil draining process of the combined transmission generator 50 is carried out: unscrew the oil drain port plug of the combined transmission generator 50, and the waste oil in the combined transmission generator 50 flows directly into the waste oil tank 47 through the oil receiving pan until no waste oil flows out of the oil drain port, and then reinstall the oil drain port plug of the combined transmission generator 50.

[0053] Next, the oil filling process of the combined transmission generator 50 is carried out: unscrew the oil overflow screw of the combined transmission generator 50, set the oil filling speed and oil filling time, and the oil filling time can be found according to different combined transmission generators 50. Figure 9As shown, the parameters set in this embodiment; confirm again that the two ball valves 33 at the inlet and outlet are open, the emergency stop button 27 has been released, and press the oil filling motor control button 25 on the console or the start button in the oil filling motor page on the touch control screen 24; the start light is on, and the second drive motor 32 drives the metering pump 30 to run and start oil filling; when it is necessary to stop oil filling, press the oil filling motor control button 25 on the console again when the indicator light is on, and the second drive motor 32 stops, or press the stop button on the touch control screen 24 to reset the timer; when it is necessary to pause oil filling midway, press the pause button on the touch control screen 24 (pause is displayed only when it is in the starting state), as shown in FIG. Figure 10 When you need to resume oiling, press the resume button on the touch control screen 24 (restore is displayed only when in paused state), as shown Figure 11 As shown; the timer stops timing during the pause and the timer does not return to zero; until oil overflows from the oil overflow port of the combined drive generator 50, stop filling the oil; after almost no oil flows out of the oil overflow port, reinstall the oil overflow screw plug of the combined drive generator 50.

[0054] Next, the cycle cleaning and filtration process is carried out:

[0055] Observe the liquid level of the combined transmission generator 50 in the liquid level observation window on the combined transmission generator 50 to ensure that it is within the normal range, press the exhaust port to exhaust the air, and set the speed and running time of the combined transmission generator 50. Figure 12 The parameters set in this embodiment are shown as follows; press the generator drive control button 26 on the console or the start button in the generator page on the touch control screen 24; the start light comes on, and the first servo motor 18 drives the combined transmission generator 50 to rotate through the motor spline shaft sleeve 19, starting the cycle operation; when it is necessary to stop the cycle, press the generator drive control button 26 on the console again when the light is on, and the first servo motor 18 stops, or press the stop button on the touch control screen 24 to reset the timer; when it is necessary to pause the operation, press the pause button on the touch control screen 24 (the pause button is displayed only when the operation is started); when it is necessary to resume the operation, press the resume button on the touch control screen 24 (the resume button is displayed only when the operation is paused); the timer stops during the pause and the timer does not reset to zero; after the set operating time is reached, the first servo motor 18 stops, the start light goes off, and the timer resets to zero; on the generator and oil injection motor pages, real-time oil temperature, pressure, circulation flow rate, and oil cleanliness level can be monitored. After each stop of the combined drive generator 50 cycle filter, the data recording page will record the data before the stop, including the following items: stop date, stop time, the system's circulation flow, pressure, temperature and oil cleanliness level before the stop, etc. Figure 13 shown.

[0056] After completing the above working process, press the emergency stop button 27 to prevent malfunction; then close the two ball valves 33, remove the hydraulic oil pipe joints of the oil inlet and outlet of the combined transmission generator 50, screw back the covers of the oil inlet and outlet of the combined transmission generator 50, push the servo motor seat 17 to reset, until the locking pin 20 is stuck in the limit groove 22 on the front side of the limit strip 21. In the initial stage of pushing, it is necessary to lift the locking pin 20 and then push, put the lifting ring 12 of the combined transmission generator 50 into the pin of the lifting head 11, and unscrew the clamp 15. Tighten the screws, take out the clamp 15, push the transfer hanger to disengage the connecting flange of the combined transmission generator 50 and the connecting flange 14 on the connecting flange seat 13, and have two operators grab the two handles on the transfer hanger respectively, lift the transfer hanger with the combined transmission generator 50 off the work surface, and place the combined transmission generator 50 on the bracket 48, remove the pin on the bottom of the lifting head 11, disengage the combined transmission generator 50 and the transfer hanger, push open the transfer hanger, and take out the lifting ring 12 on the combined transmission generator 50.
