Description

Technical Field

[0001] This utility model relates to the field of aircraft engine maintenance, and in particular to a device for storing Rolls-Royce engines. Background Technology

[0002] If a helicopter is grounded for an extended period during operation, the engine must be sealed with an oil seal to ensure its sealing performance and normal operation when it is put back into use. The oil seal requires that the oil sealant be injected evenly into the Rolls-Royce 250 engine at a pressure of 50 PSI to ensure that the oil seal can effectively seal under high pressure, preventing oil leakage or external contamination, thereby ensuring the lubrication and sealing effect inside the engine.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Existing sealing tools are operated by manual pressure pressurizers, resulting in unstable pressure and safety hazards. This leads to low sealing efficiency, requires two operators, and typically takes 30 minutes to complete. Unstable pressure also affects the constant pressure at which the oil seal oil enters the engine, negatively impacting the sealing effect. Furthermore, during oil sealing operations, personnel must remain near the engine, posing a certain degree of danger and increasing the risk of accidents or operational errors.

[0004] Therefore, those skilled in the art have provided an apparatus for storing Rolls-Royce engines to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for sealing Rolls-Royce engines. This invention uses a controller to control the extension of the inner rod of the electric telescopic rod, which enables rapid adjustment of the pressure inside the fixing box, thereby ensuring the stability and controllability of the system pressure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A device for storing Rolls-Royce engines includes a base plate and a pressure regulating mechanism. A base is fixedly mounted on the upper end of the base plate, an electric pump is fixedly mounted on the upper end of the base plate, a controller is fixedly mounted on the upper end of the electric pump, a pressure gauge is fixedly mounted on one side of the front end of the electric pump, and an oil outlet pipe is fixedly mounted on the rear side of the electric pump.

[0008] The pressure regulating mechanism includes a fixed box, with connecting flanges fixedly installed at both the input and output ends of the fixed box. A pressure relief cover is fixedly installed at the bottom of the fixed box, and fixed plates are fixedly installed on both sides of the outer end of the pressure relief cover. An electric telescopic rod is fixedly installed at the upper end of the fixed box, and a movable block is fixedly installed at the lower end of the electric telescopic rod.

[0009] Furthermore, an oil inlet pipe is fixedly installed on the other side of the front end of the electric pump.

[0010] Furthermore, the controller is electrically connected to the pressure gauge and the electric pump.

[0011] Furthermore, one of the two connecting flanges is fixedly connected to the oil outlet pipe, and the two fixing plates are positioned above the input and output ends of the fixing box.

[0012] Furthermore, the inner rod of the electric telescopic rod passes through the fixed box, and the movable block is movably disposed inside the pressure relief cover.

[0013] Furthermore, the controller is electrically connected to the electric telescopic rod, and multiple pressure relief grooves are provided at the outer end of the pressure relief cover.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a device for sealing Rolls-Royce engines. A base plate is used to fix the base, which is fixed to the upper part of the base plate to ensure the electric pump does not shift. A pressure gauge displays the system pressure in real time. Simultaneously, a single-chip microcomputer controls a pressure regulating mechanism to automatically adjust the pressure, maintaining system pressure stability and preventing overpressure or underpressure, ensuring safe operation of the equipment. When the pressure is too high, the controller can automatically adjust the pressure to prevent equipment damage or safety accidents caused by excessive pressure. Furthermore, the controller can also start the electric pump to automatically draw oil and transfer it to the engine through the oil inlet pipe, thereby significantly improving work efficiency, reducing manual operation, and enhancing operational safety. This effectively solves the problems of unstable pressure, significant safety hazards, cumbersome manual operation, and low efficiency of existing manual sealing tools, ensuring the stability and safety of the oil sealing process. 2. This utility model also proposes a device for sealing Rolls-Royce engines. A controller controls the extension of the inner rod of the electric telescopic rod, and a movable block blocks the pressure relief groove inside the pressure relief cover, effectively regulating the pressure inside the fixed box, ensuring stable and controllable system pressure, and enhancing the sealing effect. The fixed plate seals the space inside the fixed box to prevent oil leakage and ensure system safety. Two connecting flanges connect to the oil outlet pipe at one end and the engine at the other, ensuring proper oil delivery and improving the sealing and reliability of the connections. This significantly enhances the unit's storage capacity and operational safety, improves operational efficiency, reduces leakage and safety hazards, and provides a more efficient and safer guarantee for storage operations.

[0025] A device for storing Rolls-Royce engines includes a base plate 1 and a pressure regulating mechanism 8. A base 2 is fixedly mounted on the upper end of the base plate 1, an electric pump 3 is fixedly mounted on the upper end of the base 2, a controller 4 is fixedly mounted on the upper end of the electric pump 3, a pressure gauge 5 is fixedly mounted on one side of the front end of the electric pump 3, an oil outlet pipe 7 is fixedly mounted on the rear side of the electric pump 3, and an oil inlet pipe 6 is fixedly mounted on the other side of the front end of the electric pump 3. The controller 4 is electrically connected to the pressure gauge 5 and the electric pump 3.

[0026] Specifically, base plate 1 is used to fix base 2, and base 2 is fixed on the upper end of base plate 1 to ensure that electric pump 3 does not shift. Pressure gauge 5 displays the system pressure in real time. At the same time, the pressure regulating mechanism 8 is controlled by a microcontroller to automatically regulate the pressure, maintain the stability of the system pressure, avoid overpressure or underpressure, and ensure the safe operation of the equipment. When the pressure is too high, controller 4 can automatically adjust the pressure to prevent equipment damage or safety accidents caused by excessive pressure. In addition, controller 4 can also start electric pump 3 to automatically draw oil and transfer it to the engine through oil inlet pipe 6, thereby greatly improving work efficiency, reducing manual operation, and enhancing operational safety.

[0027] Reference Figure 3 , Figure 4 , Figure 5 The pressure regulating mechanism 8 includes a fixed box 801. Connecting flanges 802 are fixedly installed at both the input and output ends of the fixed box 801. A pressure relief cover 803 is fixedly installed at the bottom inner end of the fixed box 801. Fixed plates 807 are fixedly installed on both sides of the outer end of the pressure relief cover 803. An electric telescopic rod 805 is fixedly installed at the upper end of the fixed box 801. A movable block 806 is fixedly installed at the lower end of the electric telescopic rod 805. One of the two connecting flanges 802 is fixedly connected to the oil outlet pipe 7. The two fixed plates 807 are located above the input and output ends of the fixed box 801. The inner rod of the electric telescopic rod 805 passes through the fixed box 801. The movable block 806 is movably installed inside the pressure relief cover 803. The controller 4 is electrically connected to the electric telescopic rod 805. Multiple pressure relief grooves 804 are opened at the outer end of the pressure relief cover 803.

[0028] Specifically, when the pressure of the electric pump 3 needs to be changed, the controller 4 controls the extension of the inner rod of the electric telescopic rod 805, and the movable block 806 blocks the pressure relief groove 804 inside the pressure relief cover 803, effectively regulating the pressure inside the fixed box 801, ensuring the stability and controllability of the system pressure, and enhancing the sealing effect. The fixed plate 807 seals the space inside the fixed box 801 to prevent oil leakage and ensure system safety. One end of the two connecting flanges 802 is connected to the oil outlet pipe 7, and the other end is connected to the engine, ensuring correct oil transmission and improving the sealing and reliability of the connection. This significantly improves the sealing capacity and operational safety of the device, increases operating efficiency, reduces leakage and safety hazards, and provides a more efficient and safer guarantee for sealing operations. The lowest point of the movable block 806 is located at the highest point inside the pressure relief cover 803, ensuring that the movable block 806 will not detach from the pressure relief cover 803 during movement.

[0029] Working principle: Base plate 1 is used to fix base 2, and base 2 is fixed on the upper end of base plate 1 to ensure that electric pump 3 does not shift. Pressure gauge 5 displays the system pressure in real time. The pressure regulating mechanism 8 is controlled by a microcontroller to automatically regulate the pressure, maintain the system pressure stability, avoid overpressure or underpressure, and ensure equipment safety. At the same time, controller 4 can also start electric pump 3 to draw oil, and oil inlet pipe 6 transfers the oil to the engine.

[0030] Secondly, the controller 4 controls the extension of the inner rod of the electric telescopic rod 805, and the movable block 806 blocks the pressure relief groove 804 inside the pressure relief cover 803, effectively regulating the pressure inside the fixed box 801. The fixed plate 807 seals the space inside the fixed box 801 to prevent oil leakage and ensure system safety. One end of the two connecting flanges 802 is connected to the oil outlet pipe 7, and the other end is connected to the engine, ensuring correct oil transmission and improving the sealing and reliability of the connection.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
