Description

Technical Field

[0001] This invention relates to the field of aircraft manufacturing equipment technology, and in particular to an aircraft landing gear installation method and an auxiliary installation device for aircraft landing gear. Background Technology

[0002] Currently, in the aircraft production process, the assembly of aircraft landing gear is mostly completed using the most primitive hoisting method. Since the hoisting mechanism cannot control the attitude and position of the landing gear in the air after bearing it, it makes it very difficult to assemble the landing gear onto the wing, and sometimes even damages aircraft parts.

[0003] Therefore, it is necessary to enable the aircraft landing gear to adjust its attitude during installation and maintain that attitude in order to facilitate installation. Summary of the Invention

[0004] The main objective of this invention is to provide an aircraft landing gear installation method and an aircraft landing gear auxiliary installation device, which aims to keep the aircraft landing gear in a stable position during installation to facilitate installation.

[0005] To achieve the above objectives, the present invention proposes an aircraft landing gear installation method. The aircraft landing gear auxiliary installation equipment includes: an adjustment device, an AGV, and a fixing mechanism. The fixing mechanism is installed on the adjustment device and is used to fix it to the aircraft landing gear. The adjustment device is used to adjust the position and attitude of the aircraft landing gear. The AGV is located at the bottom of the adjustment device and is used to transport the aircraft landing gear. The aircraft landing gear installation method includes: fixing the aircraft landing gear to the fixing mechanism; transferring the aircraft landing gear to the installation area by the AGV; adjusting the aircraft landing gear to the installation attitude and position by adjusting the adjusting device; and manually installing the aircraft landing gear to the aircraft body.

[0006] In one embodiment, the fixing mechanism includes a first fixing mechanism and a second fixing mechanism, which are spaced apart in the vertical direction. The first fixing mechanism includes a base that is movable in the vertical direction and is used to support the bottom of the aircraft landing gear. The second fixing mechanism is used to limit the circumferential movement of the connecting part of the aircraft landing gear. The steps of fixing the device to the aircraft landing gear via the fixing mechanism include: The aircraft landing gear was lifted using a crane. Adjust the distance between the base and the second fixing mechanism to match the length from the connection part of the aircraft landing gear to the lower end; The aircraft landing gear is connected via the first fixing mechanism and the second fixing mechanism.

[0007] In one embodiment, the aircraft landing gear auxiliary installation equipment further includes a pressure sensor disposed between the adjustment device and the AGV; After the step of fixing the aircraft landing gear to the fixing mechanism, the method further includes: Set a preset weight, and compare the reading from the pressure sensor with the preset weight; When the reading value is not equal to the preset weight, the aircraft landing gear is removed from the fixing mechanism; When the reading value is equal to the preset weight, the step "transferring the aircraft landing gear to the installation area via the AGV" is executed.

[0008] In one embodiment, the step of transferring the aircraft landing gear to the installation area using the AGV includes: Set a first preset height, and lower the height of the aircraft landing gear and the aircraft landing gear auxiliary installation equipment to ensure that the height of both is lower than the first preset height.

[0009] In one embodiment, the aircraft body has a landing gear assembly station, and the landing gear assembly station is equipped with one of the transfer-type full-aircraft flexible docking system and a jack; After setting a first preset height and lowering the height of the aircraft landing gear and the aircraft landing gear auxiliary installation equipment to ensure that both heights are below the first preset height, the following steps are included: Set the first preset range, the second preset range, the third preset range, and the fourth preset range; When the landing gear assembly station is equipped with the transfer-type flexible docking system, the AGV is moved so that the distance between the aircraft landing gear and the transfer-type flexible docking system in the longitudinal direction is within a first preset range; the AGV is moved so that the distance between the aircraft landing gear auxiliary installation equipment and the transfer-type flexible docking system in the lateral direction is within a second preset range.

[0010] After setting the first preset range, the second preset range, the third preset range, and the fourth preset range, the following steps are also included: When the landing gear assembly station is equipped with the jack, the AGV is moved so that the distance between the aircraft landing gear and the jack in the front-to-back direction is within a third preset range; the AGV is moved so that the distance between the aircraft landing gear auxiliary installation equipment and the jack in the left-to-right direction is within a fourth preset range.

[0011] The adjustment device enables the fixing mechanism to move linearly in the front-back, up-down, and left-right directions, and to rotate along the axis in the up-down and left-right directions; The step of adjusting the aircraft landing gear to the installation attitude and installation position by adjusting the adjustment device includes: The fixing mechanism is moved in a straight line by adjusting the adjusting device, so that the aircraft landing gear is in the installation position; The fixing mechanism is rotated by adjusting the adjusting device to bring the aircraft landing gear to the installation position.

[0012] The aircraft landing gear auxiliary installation equipment also includes an operating platform, which includes a first operating frame and a second operating frame. The first operating frame is fixedly installed on the adjustment device and located on one side of the fixing mechanism in the front-rear direction. The top of the first operating frame is used for climbing operations. The second operating frame is located on one side of the adjustment device in the left-right direction and is movably installed on the first operating frame in the front-rear direction. The second operating frame has an extended position and a retracted position in its active stroke. The extended position is arranged opposite to the fixing mechanism in the left-right direction. The top of the second operating frame is used for climbing operations. The steps of manually installing the aircraft landing gear onto the aircraft body include: Move the second operating frame to the extended position; Manually board the second control frame to connect the aircraft landing gear and the aircraft body via pivot pins.

[0013] Following the step of manually installing the aircraft landing gear onto the aircraft body, the process also includes: Release the fixing mechanism from the aircraft landing gear; Move the second operating frame to the storage position; The aircraft landing gear auxiliary installation equipment is lowered to the second preset height after the second preset height is set. The AGV is used to move the aircraft landing gear auxiliary installation equipment outside the installation area.

[0014] The present invention also proposes an aircraft landing gear auxiliary installation device, comprising: A fixing mechanism used for fixed connection with the aircraft landing gear; An adjustment device is provided for installation on the fixing mechanism. The adjustment device is used to adjust the fixing mechanism by linear movement in the front-back, up-down, and left-right directions, and to adjust the fixing mechanism by rotation along the axis in the up-down and left-right directions. An AGV, located at the bottom of the regulating device, is used to transport the regulating device. A pressure sensor is disposed between the regulating device and the AGV; The operating platform includes a first operating frame and a second operating frame. The first operating frame is fixedly installed on the adjusting device and located on one side of the fixing mechanism in the front-rear direction. The top of the first operating frame is used for climbing operations.

[0022] Currently, the assembly of aircraft landing gear in most aircraft manufacturing processes is accomplished using the most primitive method of hoisting. Because the hoisting mechanism cannot control the attitude and position of the landing gear in the air after bearing it, assembling the landing gear onto the wing is extremely difficult, sometimes even damaging aircraft components. Therefore, it is necessary to enable the aircraft landing gear to adjust its attitude during installation and maintain that attitude to facilitate installation.

[0023] This invention proposes a method for installing aircraft landing gear. The method is implemented using aircraft landing gear auxiliary installation equipment, which includes an adjustment device, an AGV (Automated Guided Vehicle), and a fixing mechanism. The fixing mechanism is installed on the adjustment device and is used to fix it to the aircraft landing gear. The adjustment device is used to adjust the position and attitude of the aircraft landing gear. The AGV is located at the bottom of the adjustment device and is used to transport the aircraft landing gear.

[0024] To achieve the effect of adjusting the position and attitude of the aircraft landing gear and maintaining stability, refer to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of an aircraft landing gear installation method according to the present invention.

[0025] The aircraft landing gear installation method includes: Step S1: Securely connect the fixed mechanism to the aircraft landing gear; Step S3: Transfer the aircraft landing gear to the installation area using the AGV; Step S4: Adjust the adjustment device to adjust the aircraft landing gear to the installation attitude and installation position; Step S5: The aircraft landing gear is manually installed onto the aircraft body.

[0026] The landing gear is fixedly connected to the aircraft via a securing mechanism, ensuring it remains stationary and prevents movement, thus facilitating its connection and installation to the aircraft body. After the landing gear is securely connected, an AGV (Automated Guided Vehicle) moves it to an installation area near the aircraft body for initial positioning. Then, an adjustment device performs fine-tuning to correct and maintain the landing gear's position and attitude, allowing for manual installation onto the aircraft body.

[0027] Because aircraft landing gear auxiliary installation equipment may transport aircraft landing gear of different sizes (nose and rear landing gear), the fixing mechanism needs to be able to accommodate aircraft landing gear of different sizes.

[0028] This invention provides a method for installing aircraft landing gear, referring to... Figure 2 , Figure 2 This is a flowchart illustrating a second embodiment of an aircraft landing gear installation method according to the present invention.

[0029] In one embodiment, the fixing mechanism includes a first fixing mechanism and a second fixing mechanism, which are spaced apart in the vertical direction. The first fixing mechanism includes a base that is movable in the vertical direction and is used to support the bottom of the aircraft landing gear. The second fixing mechanism is used to limit the circumferential movement of the connecting part of the aircraft landing gear. Step S1 includes: Step S11: Lift the aircraft landing gear using a crane; Step S12: Adjust the distance between the base and the second fixing mechanism to match the length from the connection part of the aircraft landing gear to the lower end; Step S13: Connect the aircraft landing gear through the first fixing mechanism and the second fixing mechanism.

[0030] The aircraft landing gear has a connection point for a second fixing mechanism. The length from the connection point to the bottom varies depending on the size of the landing gear. Therefore, the distance between the base and the second fixing mechanism is adjusted to match the length from the connection point to the bottom of the aircraft landing gear, ensuring that the first and second fixing mechanisms can be matched to the aircraft landing gear. Since the first fixing mechanism supports the aircraft landing gear from the bottom, and the second fixing mechanism limits the circumferential movement of the aircraft landing gear, the aircraft landing gear is fixed in place under the influence of gravity.

[0031] Because different aircraft have different landing gear weights, it is necessary to prevent the use of the wrong aircraft landing gear.

[0032] This invention provides a method for installing aircraft landing gear, referring to... Figure 3 , Figure 3 This is a flowchart illustrating a third embodiment of an aircraft landing gear installation method according to the present invention.

[0033] The aircraft landing gear auxiliary installation equipment also includes a pressure sensor, which is disposed between the adjustment device and the AGV; After step S1, the following also includes: Step S21: Set a preset weight, and compare the reading from the pressure sensor with the preset weight; Step S22: When the reading value is not equal to the preset weight, the aircraft landing gear is removed from the fixing mechanism; Step S23: When the reading value is equal to the preset weight, execute step "S3".

[0034] If the reading is not equal to the preset weight, it indicates that the aircraft landing gear is incorrect and needs to be replaced with the correct landing gear. If the reading is equal to the preset weight, it indicates that the aircraft landing gear model is correct and the next step can be performed.

[0035] In order to move the aircraft landing gear and landing gear auxiliary installation equipment to the installation area without colliding with the main body of the aircraft, it is necessary to lower the overall height before moving them.

[0036] This invention provides a method for installing aircraft landing gear, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the fourth embodiment of an aircraft landing gear installation method according to the present invention.

[0037] Step S3 includes: Step S31: Set a first preset height and lower the height of the aircraft landing gear and the aircraft landing gear auxiliary installation equipment to ensure that both heights are lower than the first preset height.

[0038] Lower the height of the aircraft landing gear and aircraft landing gear auxiliary installation equipment to below the first preset height to ensure transportation.

[0039] The aircraft body has a landing gear assembly station, which is equipped with either the transfer-type full-aircraft flexible docking system or a jack. Therefore, there are two different installation scenarios for the aircraft landing gear assembly station, and the corresponding installation areas are different for different installation scenarios.

[0040] This corresponds to a scenario where the landing gear assembly station is equipped with the transfer-type flexible docking system for the entire aircraft. This embodiment of the invention provides an aircraft landing gear installation method, referring to... Figure 5 , Figure 5 This is a flowchart illustrating the fifth embodiment of an aircraft landing gear installation method according to the present invention.

[0041] After step S31, the following is included: Step S32: Set the first preset range, the second preset range, the third preset range, and the fourth preset range; Step S33: When the landing gear assembly station is equipped with the transfer-type flexible docking system, the AGV is moved so that the distance between the aircraft landing gear and the transfer-type flexible docking system in the front-rear direction is within a first preset range; the AGV is moved so that the distance between the aircraft landing gear auxiliary installation equipment and the transfer-type flexible docking system in the left-right direction is within a second preset range.

[0042] The jack is provided at the landing gear assembly station.

[0043] This invention provides a method for installing aircraft landing gear, referring to... Figure 6 , Figure 6 This is a flowchart illustrating the sixth embodiment of an aircraft landing gear installation method according to the present invention.

[0044] Step S32 is followed by: Step S34: When the jack is installed at the landing gear assembly station, the AGV is moved so that the distance between the aircraft landing gear and the jack in the front-to-back direction is within a third preset range; the AGV is moved so that the distance between the aircraft landing gear auxiliary installation equipment and the jack in the left-to-right direction is within a fourth preset range.

[0045] In order to precisely adjust the position and attitude of the aircraft landing gear.

[0046] This invention provides a method for installing aircraft landing gear, referring to... Figure 7 , Figure 7 This is a flowchart illustrating the seventh embodiment of an aircraft landing gear installation method according to the present invention.

[0047] The adjustment device enables the fixing mechanism to move linearly in the front-back, up-down, and left-right directions, and to rotate along the axis in the up-down and left-right directions; Step S4 includes: Step S41: Adjust the adjusting device to move the fixing mechanism in a straight line so that the aircraft landing gear is in the installation position; Step S42: Rotate the fixing mechanism by adjusting the adjusting device to bring the aircraft landing gear to the installation position.

[0048] The structure of the adjustment device includes: a first adjustment mechanism, a second adjustment mechanism, and a drive mechanism. The first adjustment mechanism has a first base; the second adjustment mechanism has a second base and a third base, the second base being rotatably mounted on the first base along a vertical axis, and the third base being rotatably mounted on the second base along a horizontal axis; a fixing mechanism is mounted on the third base; the drive mechanism is drivenly connected to the second and third bases to adjust the position and posture of the fixing mechanism in space. The first adjustment mechanism further includes: a fourth base and a fifth base; the fifth base is movably mounted on the fourth base along a front-back direction; a sixth base is movably mounted on the fifth base along a vertical direction; and the first base is movably mounted on the sixth base along a horizontal direction. Fine adjustment is achieved by driving the relative movement and rotation between the two connected bases through the drive mechanism.

[0049] To allow workers to operate from a position that is easy to observe and control.

[0050] This invention provides a method for installing aircraft landing gear, referring to... Figure 8 , Figure 8 This is a flowchart illustrating the eighth embodiment of an aircraft landing gear installation method according to the present invention.

[0051] The aircraft landing gear auxiliary installation equipment also includes an operating platform, which includes a first operating frame and a second operating frame. The first operating frame is fixedly installed on the adjustment device and located on one side of the fixing mechanism in the front-rear direction. The top of the first operating frame is used for climbing operations. The second operating frame is located on one side of the adjustment device in the left-right direction and is movably installed on the first operating frame in the front-rear direction. The second operating frame has an extended position and a retracted position in its active stroke. The extended position is arranged opposite to the fixing mechanism in the left-right direction. The top of the second operating frame is used for climbing operations. Step S5 includes: Step S51: Move the second operating frame to the extended position; Step S52: Manually board the second control frame to connect the aircraft landing gear and the aircraft body via pivot pins.

[0052] By extending the second operating frame and moving it to the extended position, the worker can be positioned on the side of the connection position that facilitates operation.

[0053] After the aircraft landing gear is installed, the landing gear connection needs to be disconnected and the landing gear auxiliary installation equipment needs to be removed.

[0054] This invention provides a method for installing aircraft landing gear, referring to... Figure 9 , Figure 9 This is a flowchart illustrating the ninth embodiment of an aircraft landing gear installation method according to the present invention.

[0055] After step S5, the following also includes: Step S61: Disconnect the fixing mechanism from the aircraft landing gear; Step S62: Move the second operating frame to the storage position; Step S63: Set the second preset height, and lower the aircraft landing gear auxiliary installation equipment to the second preset height; Step S64: Move the aircraft landing gear auxiliary installation equipment outside the installation area using the AGV.

[0056] The fixing mechanism is disconnected from the aircraft landing gear to facilitate the movement of the aircraft landing gear auxiliary installation equipment. The second operating frame is moved to the storage position to reduce the size of the aircraft landing gear auxiliary installation equipment and minimize the possibility of collision. A second preset height is set, and the aircraft landing gear auxiliary installation equipment is lowered to the second preset height to prevent collision with the aircraft body when the aircraft landing gear auxiliary installation equipment is removed. At this time, the aircraft landing gear auxiliary installation equipment can be transferred using an AGV.
