Description

Technical Field

[0001] This invention relates to the field of hydraulic variable pitch propeller governor testing technology, specifically a ground testing device for hydraulic variable pitch propeller governors. Background Technology

[0002] A hydraulic variable pitch propeller governor is a device that adjusts the propeller pitch through a hydraulic system, primarily used for optimizing the power systems of aircraft or ships. Testing the hydraulic variable pitch propeller governor is a crucial step in ensuring its safety and reliability.

[0003] A ground testing device for a hydraulic variable-pitch propeller governor is disclosed in invention patent CN117644995A. The device includes a base and a speed selection adjustment assembly. A drive motor is mounted on one end of the base, and a governor connected to the drive motor is mounted on the other end. Multiple oil passages are provided within the base, with their connection ports connected to oil ports on the governor. External ports of the oil passages are located on the outer wall of the base and fitted with connectors. The speed selection adjustment assembly has a support, on which a horizontally positioned speed selection motor is mounted.

[0048] This invention provides a ground testing device for a hydraulic variable pitch propeller governor. It has the following beneficial effects:

[0049] 1. This ground testing device for a hydraulic variable-pitch propeller governor utilizes a monitoring mechanism with cameras that can move horizontally and vertically to monitor for oil leaks. Existing testing devices rely on workers to visually inspect the governor for leaks during sealing tests, but these tests are lengthy, making it difficult for workers to observe leak locations in real time. Therefore, this monitoring mechanism, using cameras that can move horizontally and vertically, monitors for oil leaks and their locations to solve the aforementioned problem.

[0050] 2. This ground test device for the hydraulic variable pitch propeller governor uses a connecting box to house the camera, preventing it from coming into contact with oil stains that are difficult to clean. A retractable baffle is installed in the connecting box; when the baffle is raised, it rubs against the outer plate with brush strips, promoting drying of the surface near the camera and preventing the baffle from becoming damp and causing unclear images; when the baffle is lowered, it remains inside the connecting box, preventing the camera from coming into contact with oil stains.

[0051] 3. The ground test device for the hydraulic variable pitch propeller governor is equipped with a processing mechanism, which includes multiple cylinders and an oil suction shell outside the cylinders. The contact component and the processing mechanism work together to control the oil suction shell to suction oil from the installation channel, thereby completing the oil suction work of the installation channel.

[0052] 4. This ground test device for the hydraulic variable pitch propeller governor, by setting up a contact assembly, adjusts the stroke of the electric push rod in the adjusting component according to whether there is an installation column in the installation channel to be suctioned, thereby controlling the height of the suction shell in the installation channel, completing the oil receiving work at the bottom of the installation column and the oil suction work inside the installation channel. The direction of the contact assembly is controlled by a third motor. When the suction cup in the contact assembly is facing upward, the contact assembly is in oil suction mode. When the suction cup in the contact assembly is facing downward, the flared tube and the pad squeeze the cylinder and the suction shell, completing the disassembly work of the cylinder and the suction shell.

[0062] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0063] like Figures 1-8 As shown, the present invention provides a technical solution including a test bench 1;

[0064] Installation channel 2 is located inside test bench 1. There are several installation channels 2, which are evenly distributed.

[0065] Mounting frame 3 is installed inside mounting channel 2. The bottom of mounting frame 3 is provided with a first mounting post, which is locked inside mounting channel 2.

[0066] Mounting base 7 is installed inside the mounting channel 2. The bottom of the mounting base 7 is provided with a second mounting post, which is locked inside the mounting channel 2.

[0067] The first motor housing 8 is installed outside the mounting base 7, and the first motor is installed inside the first motor housing 8;

[0068] Speed ​​controller 9 is installed outside the mounting base 7 and is connected to the output terminal of the first motor.

[0069] Mounting plate 5, four mounting plates 5 are installed on the outside of the test bench 1, and the mounting plates 5 are arranged around the test bench 1.

[0070] The monitoring mechanism 4 is installed inside the mounting frame 3. The monitoring mechanism 4 includes a second push rod 405, which is set as an electric push rod. A connection box 406 is installed on the outside of the second push rod 405. A camera 411 is installed inside the connection box 406. The second push rod 405 is used to control the position of the camera 411 in the horizontal direction.

[0071] The processing mechanism 6 is installed on the outside of the mounting plate 5. The processing mechanism 6 includes a third push rod 605, which is configured as an electric push rod. A contact component 607 is provided on the outside of the third push rod 605. The third push rod 605 is used to adjust the relative position of the contact component 607 and the mounting channel 2.

[0072] Before using the equipment, the processing mechanism 6 is used to treat the installation channel 2 to prevent impurities and oil stains in the installation channel 2 from affecting the stability of the mounting frame 3 and the mounting base 7. Then, the user conducts a sealing test on the speed controller 9. During the test, the monitoring mechanism 4 is in the open state to monitor the speed controller 9 for any oil leaks. If an oil leak is detected, the processing mechanism 6 is adjusted to block the installation channel 2 in use and to block and drain the oil from surrounding installation channels 2.

[0073] Monitoring agency 4 also includes:

[0074] The first push rod 401 is an electric push rod and is installed inside the mounting frame 3.

[0075] The first slide plate 402 is slidably connected inside the mounting frame 3, and the first slide plate 402 is connected to the telescopic end of the first push rod 401;

[0076] The first lifting frame 403 is composed of an electric push rod in the vertical direction and a platform frame, and the first lifting frame 403 is installed on the top of the first slide plate 402;

[0077] The second motor housing 404 is installed outside the first lifting frame 403. The second motor is installed inside the second motor housing 404. The second push rod 405 is connected to the output end of the second motor.

[0078] L-shaped rod 407 is installed on top of connector box 406;

[0079] Outer plate 408 is installed on the outside of L-shaped rod 407. Brush strips are installed on the outside of outer plate 408. Multiple brush strips are provided and are evenly distributed.

[0080] The first lifting rod 409 is configured as an electric push rod and is installed at the bottom of the L-shaped rod 407;

[0081] The baffle 410 is made of transparent material and is connected to the telescopic end of the first lifting rod 409.

[0082] During the sealing performance test of the speed controller 9, the first lifting rod 409 is activated, causing the baffle 410 to move downwards and gradually enter the connecting box 406. The first push rod 401 is then activated to reciprocating motion mode, causing the first slide plate 402 to move within the mounting frame 3. The first slide plate 402 then moves the first lifting frame 403, the second motor box 404, the second push rod 405, the connecting box 406, and the camera 411, thereby adjusting the monitoring range. By adjusting the stroke of the electric push rod in the vertical direction of the first lifting frame 403 and the second push rod 405, the position of the camera 411 in the horizontal and vertical directions is adjusted.

[0083] When the connecting box 406 is away from the speed controller 9, the stroke of the first lifting rod 409 is adjusted periodically. The first lifting rod 409 drives the baffle 410 to move in the vertical direction. The baffle 410 rubs against the outer plate 408 with the brush strip, promoting the drying of the close surface of the baffle 410 and the camera 411.

[0084] By setting up a monitoring mechanism 4, a camera 411 capable of moving horizontally and vertically is used to monitor whether there is an oil leak in the speed governor 9. In existing testing equipment, during the speed governor 9 sealing test, workers observe whether the speed governor 9 is leaking oil. However, the test is lengthy, making it difficult for workers to observe the location of the leak in real time. Therefore, the monitoring mechanism 4, using a camera 411 capable of moving horizontally and vertically, monitors whether the speed governor 9 is leaking oil and the location of the leak, thus solving the aforementioned problem.

[0085] By setting up a connection box 406, the camera 411 is placed inside the connection box 406, preventing the camera 411 from coming into contact with oil stains that are difficult to clean. By setting up a liftable baffle 410 in the connection box 406, when the baffle 410 is raised, it rubs against the outer plate 408 with brush strips, promoting the drying of the surface of the baffle 410 and the camera 411 that are close together, preventing the baffle 410 from being damp and causing unclear images; when the baffle 410 is lowered, it is inside the connection box 406, preventing the camera 411 from coming into contact with oil stains.

[0086] Processing unit 6 also includes:

[0087] Connector 601 is mounted on the outside of mounting plate 5;

[0088] The slide 602 is formed inside the connecting frame 601;

[0089] The second slide plate 603 is slidably connected to the inside of the slide groove 602;

[0090] The fourth push rod 608 is an electric push rod, which is installed inside the slide groove 602. The second slide plate 603 is connected to the telescopic end of the fourth push rod 608.

[0091] The third motor housing 604 is installed outside the second slide plate 603. The third motor is installed inside the third motor housing 604. The third push rod 605 is connected to the output end of the third motor.

[0092] The outer frame 606 is connected to the telescopic end of the third push rod 605, and the outer frame 606 is connected to the contact assembly 607.

[0093] The first semi-ring plate 609 is installed on the outside of the mounting plate 5, and multiple first semi-ring plates 609 are provided.

[0094] The fifth push rod 610 is an electric push rod and is installed on the outside of the connecting frame 601.

[0095] Connecting plate 611, which is connected to the telescopic end of the fifth push rod 610;

[0096] Adjusting column 612, the adjusting column 612 is set as an electric push rod, the adjusting column 612 is installed on the outside of the connecting plate 611, and multiple adjusting columns 612 are provided;

[0097] The second semi-ring plate 613 is connected to the telescopic end of the adjusting column 612. Multiple second semi-ring plates 613 are provided. A cylinder with an internal and bottom hollow is provided between the first semi-ring plate 609 and the second semi-ring plate 613, and an oil-absorbing shell is fitted on the outside of the cylinder.

[0098] An adjusting rod 614 is installed on the top of the second semi-ring plate 613, and a top plate 615 is installed on the top of the adjusting rod 614.

[0099] Before using the equipment, the fifth push rod 610 is in its initial state, with the cylinder clamped between the first semi-ring plate 609 and the second semi-ring plate 613, and the top plate 615 positioned above the cylinder. When it is necessary to use the cylinder and the oil suction shell to suction oil from the installation channel 2, the fourth push rod 608 is activated. The fourth push rod 608 drives the second slide plate 603 to move inside the slide groove 602. The second slide plate 603 drives the third motor housing 604, the third push rod 605, the outer frame 606, and the contact component 607 to move until the contact component 607 is directly below the cylinder and the oil suction shell. Then, the contact component 607 is adjusted to pick up the cylinder and the oil suction shell. The stroke of the third push rod 605 is then adjusted, causing the third push rod 605 to move the contact component 607 to the corresponding installation channel 2. The contact component 607 is then adjusted to control the cylinder and the oil suction shell to enter the installation channel 2 for processing.

[0100] After the oil suction operation is completed, the third motor in the third motor box 604 is turned on. The third motor drives the third push rod 605, the outer frame 606 and the contact component 607 to rotate. The contact component 607 completes the disassembly of the cylinder and the oil suction shell.

[0101] By setting up a processing mechanism 6, multiple cylinders and an oil-absorbing shell outside the cylinders are set in the processing mechanism 6. The contact component 607 and the processing mechanism 6 jointly control the oil-absorbing shell to perform oil suction processing on the installation channel 2, thereby completing the oil suction work of the installation channel 2.

[0102] Contact component 607 includes:

[0103] Adjusting component 6071 is composed of an electric push rod in the vertical direction and a connecting rod. Adjusting component 6071 is installed on the outside of the outer frame 606.

[0104] Base plate 6072, which is connected to adjusting component 6071;

[0105] A circular plate 6073 is installed on top of a base plate 6072, and multiple circular plates 6073 are provided.

[0106] A central column 6074 is installed on the top of a circular plate 6073, and a suction cup 6078 is installed on the top of the central column 6074.

[0107] Spring 6075 is mounted on top of circular plate 6073;

[0108] The flared tube 6076 is connected to the spring 6075 and is sleeved on the outside of the central column 6074.

[0109] The gasket 6077 is made of oil-absorbing material and is installed inside the flared tube 6076. The gasket 6077 is sleeved on the outside of the central column 6074.

[0110] When removing the cylinder and the oil-absorbing shell, activate the electric push rod in the vertical direction of the adjusting component 6071 to the corresponding stroke. The electric push rod drives the base plate 6072, the circular plate 6073, the central column 6074, and the suction cup 6078 to move upward. The central column 6074 and the suction cup 6078 enter the cylinder, and the suction cup 6078 gradually adheres to the cylinder. Activate the fifth push rod 610. The fifth push rod 610 drives the connecting plate 611, the adjusting column 612, and the second semi-ring plate 613 to move away from the cylinder. Adjust the electric push rod in the vertical direction of the adjusting component 6071. The electric push rod controls the central column 6074 and the suction cup 6078 to move downward. The suction cup 6078 drives the cylinder downward.

[0111] When processing installation channel 2, the stroke of the electric push rod in the vertical direction of the adjusting component 6071 is adjusted according to whether there is an installation column in installation channel 2. If there is an installation column in installation channel 2, the electric push rod in the adjusting component 6071 drives the central column 6074, suction cup 6078 and cylinder to move upward. The cylinder and the oil suction shell enter the installation channel 2, and the oil suction shell contacts the installation column to catch the oil and prevent the oil from falling down along this installation channel 2 and the installation column.

[0112] If the installation channel 2 does not have an installation column, the electric push rod in the adjusting component 6071 drives the central column 6074, suction cup 6078 and cylinder to move upward. During the upward movement of the cylinder and the oil suction shell, the oil suction shell extends beyond the installation channel 2 and is positioned on the test bench 1 to absorb excess oil.

[0113] After the user cleans the oil stains on the test bench 1, the contact component 607 and the processing mechanism 6 use a brand new cylinder and oil-absorbing shell to perform secondary treatment on the oil-stained installation channel 2.

[0114] After the oil suction operation is completed, the electric push rod in the adjusting component 6071 drives the central column 6074, the cylinder, and the oil suction shell to move downwards and disengage from the installation channel 2. The third motor in the third motor box 604 is turned on, and the third motor drives the third push rod 605 and the outer frame 606 to rotate 180 degrees. The flared tube 6076 and the pad 6077 begin to slide downwards outside the central column 6074. The spring 6075 is stretched, and the cylinder and the oil suction shell gradually detach from the suction cup 6078 under the pressure of the pad 6077 and fall downwards to the designated position.

[0115] By setting the contact component 607, the stroke of the electric push rod in the adjusting component 6071 is adjusted according to whether there is an installation column in the installation channel 2 to be suctioned, thereby controlling the height of the oil suction shell in the installation channel 2, completing the oil receiving work at the bottom of the installation column and the oil suction work inside the installation channel 2. The direction of the contact component 607 is controlled by the third motor. When the suction cup 6078 in the contact component 607 is facing upward, the contact component 607 is in the oil suction mode. When the suction cup 6078 in the contact component 607 is facing downward, the flared tube 6076 and the pad 6077 squeeze the cylinder and the oil suction shell, completing the disassembly work of the cylinder and the oil suction shell.

[0116] Working principle: Before using the equipment, the processing mechanism 6 is used to process the installation channel 2 to prevent impurities and oil stains in the installation channel 2 from affecting the stability of the installation frame 3 and the mounting base 7.

[0117] Before using the equipment, the fifth push rod 610 is in its initial state, with the cylinder clamped between the first semi-ring plate 609 and the second semi-ring plate 613, and the top plate 615 positioned above the cylinder. When the cylinder and the oil-absorbing housing are needed to process the installation channel 2, the fourth push rod 608 is activated. The fourth push rod 608 drives the second slide plate 603 to move inside the slide groove 602. The second slide plate 603 drives the third motor housing 604, the third push rod 605, the outer frame 606, and the contact component 607 to move until the contact component 607 is directly below the cylinder and the oil-absorbing housing. Then, the contact component 607 is adjusted to pick up the cylinder and the oil-absorbing housing. The stroke of the third push rod 605 is then adjusted, causing the third push rod 605 to move the contact component 607 to the corresponding installation channel 2. The contact component 607 is then adjusted to control the cylinder and the oil-absorbing housing to enter the installation channel 2 for processing.

[0118] The user then conducted a sealing test on the speed controller 9. During the test, the monitoring mechanism 4 was in the open state to monitor in real time whether there was any oil leakage in the speed controller 9.

[0119] During the sealing performance test of the speed controller 9, the first lifting rod 409 is activated, causing the baffle 410 to move downwards and gradually enter the connecting box 406. The first push rod 401 is then activated to reciprocating motion mode, causing the first slide plate 402 to move within the mounting frame 3. The first slide plate 402 then moves the first lifting frame 403, the second motor box 404, the second push rod 405, the connecting box 406, and the camera 411, thereby adjusting the monitoring range. By adjusting the stroke of the electric push rod in the vertical direction of the first lifting frame 403 and the second push rod 405, the position of the camera 411 in the horizontal and vertical directions is adjusted, thereby monitoring for any oil leaks in the speed controller 9.

[0120] Once an oil leak is detected, adjust the treatment mechanism 6 to block the installation channel 2 in use and block the surrounding installation channels 2 to collect the oil.

[0121] Before using the equipment, the fifth push rod 610 is in its initial state, with the cylinder clamped between the first semi-ring plate 609 and the second semi-ring plate 613, and the top plate 615 positioned above the cylinder. When the cylinder and the oil-absorbing housing are needed to process the installation channel 2, the fourth push rod 608 is activated. The fourth push rod 608 drives the second slide plate 603 to move inside the slide groove 602. The second slide plate 603 drives the third motor housing 604, the third push rod 605, the outer frame 606, and the contact component 607 to move until the contact component 607 is directly below the cylinder and the oil-absorbing housing. Then, the contact component 607 is adjusted, and the cylinder and the oil-absorbing housing are removed using the contact component 607.

[0122] When removing the cylinder and the oil-absorbing shell, activate the electric push rod in the vertical direction of the adjusting component 6071 to the corresponding stroke. The electric push rod drives the base plate 6072, the circular plate 6073, the central column 6074, and the suction cup 6078 to move upward. The central column 6074 and the suction cup 6078 enter the cylinder, and the suction cup 6078 gradually adheres to the cylinder. Activate the fifth push rod 610. The fifth push rod 610 drives the connecting plate 611, the adjusting column 612, and the second semi-ring plate 613 to move away from the cylinder. Adjust the electric push rod in the vertical direction of the adjusting component 6071. The electric push rod controls the central column 6074 and the suction cup 6078 to move downward. The suction cup 6078 drives the cylinder downward.

[0123] When processing installation channel 2, the stroke of the electric push rod in the vertical direction of the adjusting component 6071 is adjusted according to whether there is an installation column in installation channel 2. If there is an installation column in installation channel 2, the electric push rod in the adjusting component 6071 drives the central column 6074, suction cup 6078 and cylinder to move upward. The cylinder and the oil suction shell enter the installation channel 2, and the oil suction shell contacts the installation column to catch the oil and prevent the oil from falling down along this installation channel 2 and the installation column.

[0124] If the installation channel 2 does not have an installation column, the electric push rod in the adjusting component 6071 drives the central column 6074, suction cup 6078 and cylinder to move upward. During the upward movement of the cylinder and the oil suction shell, the oil suction shell extends beyond the installation channel 2 and is positioned on the test bench 1 to absorb excess oil.

[0125] After the user cleans the oil stains on the test bench 1, the contact component 607 and the processing mechanism 6 use a brand new cylinder and oil-absorbing shell to perform secondary treatment on the oil-stained installation channel 2.

[0126] After the oil suction operation is completed, the electric push rod in the adjusting component 6071 drives the central column 6074, the cylinder, and the oil suction shell to move downwards and disengage from the installation channel 2. The third motor in the third motor box 604 is turned on, and the third motor drives the third push rod 605 and the outer frame 606 to rotate 180 degrees. The flared tube 6076 and the pad 6077 begin to slide downwards outside the central column 6074. The spring 6075 is stretched, and the cylinder and the oil suction shell gradually detach from the suction cup 6078 under the pressure of the pad 6077 and fall downwards to the designated position.
