Description

Technical Field

[0001] This application relates to the field of landing gear mounting vehicle technology, and more particularly to a landing gear mounting vehicle. Background Technology

[0002] Landing gear is an accessory device on the underside of an aircraft used to support the aircraft during takeoff, landing, or taxiing on land (or water) and for movement on land (or water). The landing gear is the only component that supports the entire aircraft, making it an indispensable part; without it, the aircraft cannot move on the ground. After takeoff, the landing gear can be retracted depending on flight performance. Currently, landing gear installation vehicles are used for installing landing gear on aircraft.

[0003] For example, the nose landing gear installation vehicle with announcement number CN211731856U includes a frame, a lifting mechanism, and a support mechanism. Two sets of support sleeves are vertically welded to the top of the frame. The tops of the support sleeves are rotatably connected to the lifting mechanism via bearing sleeves, and the top of the lifting screw is fixedly connected to the support mechanism. This nose landing gear installation vehicle places the nose landing gear on top of a V-block, and then raises it to the bottom of the aircraft fuselage by rotating the threads on the inner side of the handwheel and the outer end face of the lifting screw. However, this operation method... This method, due to its low level of automation, relies on manual operation of handwheels to raise and lower the landing gear. This is not only labor-intensive and time-consuming, but also requires that the handwheels on both sides drive the lifting screws synchronously. If there is a deviation, motion interference will occur, causing the lifting to stall. In addition, there is no structure on the top of the V-block to fix the landing gear. As the landing gear is raised and lowered, someone needs to hold it. Therefore, the overall number of operators is large, the cost is high, and if the landing gear is shaken and falls, it is easy to be damaged.

[0004] Therefore, the urgent technical problem to be solved is: how to adjust the position of the landing gear during the installation process, improve the accuracy of the landing gear position adjustment, and improve the convenience, reliability and efficiency of the landing gear installation.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] like Figure 1-9 As shown, this application provides a landing gear mounting vehicle, including: an AGV vehicle 1, a pitching mechanism 2, a column 3, a vertical lifting mechanism 4, a lateral translation mechanism 5, a horizontal rotation mechanism 6, an oblique movement mechanism 7, and a landing gear clamping mechanism 8; the pitching mechanism 2 is mounted on the AGV vehicle 1; the column 3 is rotatably connected to the AGV vehicle 1, one end of the pitching mechanism 2 is connected to the AGV vehicle 1, and the other end is connected to the column 3, the pitching mechanism 2 drives the column 3 to rotate; the vertical lifting mechanism 4 is disposed on the column 3; one side of the lateral translation mechanism 5 is connected to the vertical lifting mechanism 4, and the other side is connected to the horizontal rotation mechanism 6; the vertical lifting mechanism 4 drives the lateral translation mechanism 5 to move along the length direction of the column 3; the oblique movement mechanism 7 and the landing gear clamping mechanism 8 are connected to the horizontal rotation mechanism 6; the landing gear clamping mechanism 8 has a clamping jaw for clamping the landing gear 9.

[0033] As a specific embodiment of this utility model, a landing gear mounting vehicle also includes a controller (e.g., a PLC controller) and a wireless remote controller. The controller is installed inside the AGV vehicle 1, and the wireless remote controller is electrically connected to the controller. By manipulating the joystick of the wireless remote controller, commands are sent to the controller, which converts the signals into electrical signals to drive the motor or electric cylinder to start and stop. The connection method between the controller (e.g., a PLC controller) and the wireless remote controller adopts existing technology, and the control method adopts existing methods, which will not be described in detail here. The controller controls the AGV vehicle 1, the pitch mechanism 2, the column 3, the vertical lifting mechanism 4, the lateral translation mechanism 5, the horizontal rotation mechanism 6, the oblique movement mechanism 7, and the landing gear clamping mechanism 8 to achieve omnidirectional translation, lifting, or rotation of the landing gear 9.

[0034] like Figure 1 As shown, the AGV vehicle 1 includes a metal frame 11 and a drive unit 12. The drive unit 12 is mounted on the metal frame 11 and drives the metal frame 11 to move. After the metal frame 11 moves, it drives the device carried on top of it to move. The AGV vehicle 1 mainly plays a supporting role when disassembling and installing the landing gear 9, and is equipped with battery equipment to realize the functions of short-term parking and short-distance transportation. Therefore, this application has the functions of short-distance transportation and short-term parking of the landing gear 9.

[0035] In a specific embodiment of this utility model, the driving device 12 includes a servo drive motor and wheels; the servo drive motor is connected to the wheels and is used to drive the wheels to rotate, and the rotation of the wheels drives the metal frame 11 to move. The wheels are Mecanum wheels, which have omnidirectional movement function and can realize forward and backward operations, so this utility model has autonomous walking ability and high stability when moving.

[0036] In a preferred embodiment of this invention, the wheel consists of four sets of Mecanum wheels. For explanation, each set of Mecanum wheels is designed to bear a weight of 800 kg, and the four sets of Mecanum wheels can bear a total weight of 3200 kg.

[0037] As a specific embodiment of this utility model, the metal frame 11 is made of high-strength carbon steel.

The traction hook is an existing ring structure, which is convenient for pulling.

[0039] like Figure 1 As shown, a support base 31 is fixedly connected to the AGV vehicle 1. The support base 31 is perpendicular to the upper surface of the metal frame 11 and is fixedly connected to the top surface of the metal frame 11. The top of the support base 31 has a rotatable connection hole, and the column 3 is rotatably connected to the support base 31 through a rotatable connector. The rotatable connector passes through the column and the rotatable connection hole, realizing the rotatable connection between the column and the support base 31. The rotatable connector is, for example, a rotating shaft. The column 3 is rotatably connected to the support base 31, thereby realizing the rotatable connection of the column 3 to the AGV vehicle 1. The pitch mechanism 2 is used to drive the column 3 to rotate relative to the support base 31 around the rotating shaft. The rotation of the column 3 drives the mechanism and landing gear 9 connected to it to rotate.

[0040] like Figure 1 , 2 As shown, the pitch mechanism 2 includes a counterweight 21, a connecting seat 22, and a column pitch push rod 23. The counterweight 21 is fixedly mounted on the AGV vehicle 1, and is positioned on the top surface of the metal frame 11 away from the support seat 31. The counterweight 21 has a cubic structure. The connecting seat 22 is fixedly connected to the counterweight 21. One end of the column pitch push rod 23 is rotatably connected to the connecting seat 22, and the other end is rotatably connected to the column 3. A rotating connection hole is provided at the top of the connecting seat 23, through which the column pitch push rod 23 is rotatably connected to the connecting seat 22. The column has a hinge support on the side near the connecting seat 22, through which the column pitch push rod 23 is pivotally connected to the column 3. After the push rod of the column pitch push rod 23 extends, it rotates around the connecting seat 22, and the column 3 rotates at a certain angle relative to the column pitch push rod 23, and the column 3 rotates around the axis of rotation relative to the support seat 31. After the column 3 rotates around the pivot relative to the support base 31, it drives the vertical lifting mechanism 4, the lateral translation mechanism 5, the horizontal rotation mechanism 6, the oblique movement mechanism 7, the landing gear clamping mechanism 8, and the landing gear 9 to rotate as a whole.

[0041] Understandably, counterweight 21 is a heavy object used to balance, stabilize, or adjust the center of gravity of an object. It is usually made of high-density materials such as metal (such as cast iron, steel) or concrete, and its shape and size are designed according to specific needs.

[0042] As a specific embodiment of this utility model, the column pitch push rod 23 includes a cylinder and a push rod; the push rod is telescopically connected inside the cylinder; one end of the cylinder is rotatably connected to the connecting seat 22, and the other end has the push rod extending out; the end of the push rod away from the cylinder is pivotally connected to the column 3 through a hinge support.

[0043] like Figure 3As shown, the vertical lifting mechanism 4 includes a drive cylinder 41, a vertical moving slider 42, and a column slide rail 43. The drive cylinder 41 is arranged along the length of the column 3. One end of the drive cylinder 41 is fixedly connected to the top of the column 3, and the other end is connected to the vertical moving slide rail 42. The extended end of the drive cylinder 41 is connected to the vertical moving slider 42. The column slide rail 43 is arranged along the length of the column 3 on the side of the column 3 away from the pitch mechanism 2; the vertical moving slider 42 is slidably connected to the column slide rail 43, and moves along the column slide rail 43 under the driving action of the drive cylinder 41. The drive cylinder 41 is connected to the vertical moving slider 42; the drive cylinder 41 drives the vertical moving slider 42 to slide along the column slide rail 43; the lateral translation mechanism 5 is fixedly connected to the vertical moving slider 42. After the vertical moving slider 42 moves up and down along the column slide rail 43, it drives the lateral translation mechanism 5 to move up and down along the column slide rail 43.

[0044] The drive cylinder 41 of this utility model is an existing drive cylinder, such as the EGC-HD-TB series drive cylinder. Preferably, the drive cylinder 41 has a driving force of 13kN and a stroke of 750mm.

[0045] like Figure 3 As shown, the vertically moving slider 42 has a mounting hole 421, which is located on the side of the vertically moving slider 42 away from the column 3. The guide rail slider 52 is mounted in the mounting hole 421 by a fastener, thus achieving a fixed connection between the guide rail slider 52 and the vertically moving slider 42. The guide rail slider 52 is connected to the side of the vertically moving slider 42 away from the column 3.

[0046] like Figure 3 As shown, mounting holes 421 are provided on the upper and lower sides of the vertical moving slider 42. Preferably, there are two guide rail sliders 52, which are respectively connected to the upper and lower sides of the vertical moving slider 42.

[0047] like Figure 4As shown, the lateral translation mechanism 5 includes a lateral guide rail 51, a guide rail slider 52, a ball screw drive mechanism 53, a lateral moving block 54, and a screw nut block 55.

The lateral guide rail 51 is fixedly connected to the lateral moving block 54; the screw nut is fixedly connected to the guide rail slider 52. The working principle of the transverse translation mechanism 5 is as follows: the ball screw drive mechanism 53 drives the screw nut block 55 to move along its length direction; when the screw nut block 55 moves along the length direction of the ball screw drive mechanism 53, the screw nut block 55 and the guide rail slider 52 move synchronously. The screw nut block 55 moves relative to the transverse moving block 54 along the length direction of the ball screw drive mechanism 53, and the guide rail slider 52 moves relative to the transverse moving block 54 along the length direction of the ball screw drive mechanism 53. Since the transverse guide rail 51 is set parallel to the length direction of the ball screw drive mechanism 53, the guide rail slider 52 moves along the transverse guide rail 51. Since the guide rail slider 52 is fixedly connected to the vertical moving slider 42, the movement of the guide rail slider 52 relative to the transverse guide rail 51 causes the vertical moving slider 42 and the guide rail slider 52 as a whole to move relative to the transverse guide rail 51. The screw nut block 55 drives the transverse guide rail 51 and the transverse moving block 54 to move relative to the vertical lifting mechanism 4 and the guide rail slider 52.

[0048] Preferably, the two guide rail sliders 52 are respectively connected to a set of ball screw drive mechanisms 53, and the set of ball screw drive mechanisms 53 drives one guide rail slider 52 to move relative to the transverse guide rail 51.

[0049] As a specific embodiment of this utility model, the transverse moving block 54 includes one, and a set of ball screw drive mechanisms 53 are respectively arranged on the upper and lower sides of the transverse moving block 54; the set of ball screw drive mechanisms 53 are respectively connected to a guide rail slider 52.

[0050] In a specific embodiment of this utility model, the ball screw drive mechanism 53 includes a drive motor and a ball screw. The drive motor is connected to the ball screw, which is mounted on the side of the transverse moving block 54 via a connecting shaft seat. The ball screw is rotatably connected to the connecting shaft seat, and the drive motor drives the ball screw to rotate relative to the connecting shaft seat. The ball screw nut block 55 is threadedly connected to the ball screw. After the ball screw rotates, it drives the ball screw nut block 55 to rotate. The ball screw nut is fixedly connected to the guide rail slider 52, and the ball screw nut drives the guide rail slider 52 to move relative to the transverse guide rail 51.

[0051] The ball screw drive mechanism 53 of this utility model adopts an existing mechanism.

[0052] like Figure 5As shown, the horizontal rotation mechanism 6 includes a first servo motor 61, a transmission mechanism, a turntable 62, and a rotating shaft. The first servo motor 61 and the transmission mechanism are connected to the horizontal moving block 54 of the horizontal translation mechanism 5, and the first servo motor 61 and the transmission mechanism are located on the side of the horizontal moving block 54 away from the vertical moving slider 42. The turntable 62 is arranged parallel to the side of the horizontal moving block 54. The first servo motor 61 is located on one side of the turntable 62 and is connected to the transmission mechanism; the first servo motor 61 drives the transmission mechanism to move, and the transmission mechanism drives the turntable 62 to rotate relative to the horizontal moving block 54. The first servo motor 61 is an existing type, such as the SV600 series or MR-JE series. The transmission mechanism adopts a cross-shaft transmission gear structure.

[0053] like Figure 6 As shown, the transmission mechanism includes a driving gear 63 and a driven gear 64. The central axes of the driving gear 63 and the driven gear 64 intersect perpendicularly. The driving gear 63 is connected to the output shaft of the first servo motor 61. The first servo motor 61 drives the driving gear 63 to rotate, which in turn drives the driven gear 64 to rotate. A rotating shaft is rotatably connected to the center of the driven gear 64. The rotating shaft is perpendicular to the side of the transverse moving block 54 and is fixedly connected to the transverse moving block 54. The gear surface of the driven gear 64 is parallel to the side of the transverse moving block 54. Driven by the driving gear 63, the driven gear 64 rotates around the rotating shaft. When the driven gear 64 rotates, the rotating shaft remains stationary, and the driven gear 64 drives the turntable 62 connected to it to rotate relative to the transverse moving block 54. The side of the driven gear 64 away from the connection with the driving gear 63 has a connecting post 66, which is fixedly connected to the turntable 62. After the driven gear 64 rotates, it drives the turntable 62 to rotate.

[0054] like Figure 6 As shown, the driven gear 64 also has a central hole 65 through which the connecting post 66 passes. A rotating shaft is rotatably connected inside the central hole 65. The rotating shaft is connected to the central hole 65 of the driven gear 64 through a bearing. The driven gear 64 and the rotating shaft rotate smoothly relative to each other.

[0055] As a specific embodiment of this utility model, the rotating shaft is fixedly connected to the transverse translation mechanism 5, and the transverse translation mechanism 5 drives the rotating shaft, the first servo motor 61, the transmission mechanism, and the turntable 62 to move laterally as a whole.

The oblique slider 73 is slidably connected to the oblique guide rail. The oblique guide rail is parallel to the oblique drive device 72. The oblique drive device 72 is connected to the horizontal rotation mechanism 6. The oblique drive device 72 is connected to the oblique slider 73, and the oblique drive device 72 drives the oblique slider 73 to move along the oblique guide rail. The oblique movement connecting plate 71 and the oblique guide rail as a whole move relative to the horizontal rotation mechanism 6 in the driving direction of the oblique drive device 72. The oblique movement mechanism 7 is used to drive the landing gear 9 to move obliquely, so as to insert the lower end pin of the landing gear 9 into the aircraft bushing.

[0057] In a specific embodiment of this utility model, the inclined guide rail adopts an existing guide rail, as long as the inclined slider 73 can move along the length direction of the inclined guide rail. The inclined drive device 72 adopts an existing drive device, which can drive the inclined slider 73 to move along the inclined guide rail, and will not be described in detail here.

[0058] As a specific embodiment of this utility model, the oblique moving mechanism 7 includes one or more sets. When there are multiple sets of oblique moving mechanisms 7, multiple sets of oblique moving mechanisms 7 are set according to the actual spatial position to avoid positional interference between the multiple sets of oblique moving mechanisms 7, and the multiple sets of oblique moving mechanisms 7 do not work at the same time to avoid interference.

[0061] like Figure 9As shown, a second servo motor 86 is installed on one side of the fixed arm 84. The second servo motor 86 is connected to a roller 85 located on the side of the fixed arm 84 near the swing arm 83 via a chain. When the second servo motor 86 rotates, it drives the chain to rotate, which in turn drives the roller 85 connected to the fixed arm 84 to rotate. This connection method is used. After the roller 85 rotates, the roller 85 connected to the fixed arm 84 drives the landing gear 1 to rotate along its own axis, slowly adjusting it to the direction corresponding to the aircraft mounting base to ensure accuracy during angle adjustment. The clamping force is 8kN, and the clamping range is...

[0062] The second servo motor 86 used in this invention is an existing servo motor, such as the SMCL EHF series or RM-GB series.
