Description

LIFTING DEVICE FOR INSTALLATION OF EXTERNAL STORES ONTO AIRCRAFT}

The present invention relates to an apparatus for mounting an aircraft external mount, and more particularly, to an apparatus for mounting an aircraft external mount for allowing an external attachment such as a missile to be mounted on an aircraft.

Military aircraft such as fighters are equipped with external attachments, such as missiles, on the wings outside the fuselage. To mount a missile on an aircraft, the operator must attach and detach the individual missile.

At this time, the external mounting such as a missile is too heavy for people to use a hydraulic or electric lift device that can support and move the mounting to move up and down.

Conventional hydraulic or electric lift devices raise and lower the table using ball screws, chains, and wires.

1 and 2 show a conventional electric and hydraulic lift device.

As shown in FIG. 1, the height of the table is automatically adjusted by driving a motor by measuring the load of the mounting 10 mounted on the table 100, or as shown in FIG. 2, as shown in FIG. 2. 6) Drive the X link to raise and lower the table.

In FIG. 2, 3a, 4a, 5, 7a, and 8a are constrained rotation center points, and 3b and 4b perform a sliding motion constrained when the table 1 is moved up and down by expansion and contraction of the cylinder.

Both of the tables shown in Figs. 1 and 2 raise and lower the table while keeping the level with the bottom surface, so it is impossible to tilt the table inclined with respect to the floor surface. This is not suitable for use as a device for installing an external attachment to the wing structure inclined left and right when viewed from the side of the aircraft.

As an alternative to this, there is an aircraft exterior mounting apparatus (registration No. 10187187, registered on April 21, 2011), which has been developed and published in the paper. The aircraft exterior mounting device has been developed for the purpose of mounting large and heavy external attachments to aircraft.

FIG. 3 shows a conventional hydraulic lift device (registration 1031872).

As shown in FIG. 3, the conventional aircraft exterior mounting apparatus mounts external mounts on two pedestals 50 and connects the towing unit 11 to the towing vehicle to be moved or steered by manpower. Done.

The lifting frame 20 is rotated by the expansion and contraction of a piston rod (not shown) implemented by operating the handle 63 about the lifting frame fixing shaft 21 to raise and lower the loading frame 30.

In addition, the stacking frame 30 is rotated about the stacking frame fixed shaft 31 by stretching and contracting the tilting bar 70 operated by the tilting handle 72, thereby increasing the height of the pedestal 50 on the left and right sides. It is different and the left and right are tilted.

In addition, the pedestal 50 lying on the rail 40 can be moved along the rail 40 individually, and can be fixed in a specific position by the fastener 52. As a result, the mounting may be mounted on one pedestal 50 or on both, depending on the mounting.

However, since the pedestal 50 does not have a shape characteristic of the seating portion 51 having a rounded plane and a structure in which the pedestal 50 rotates about the center, a large and heavy mounting is parallel to the length of the lift. It can only be mounted in the direction of the lift, so it is not possible to mount the mount in the longitudinal direction and inclined.

Therefore, in the conventional aircraft exterior mounting apparatus, when mounting the mount mounted on the pedestal 50 to the aircraft (mainly mounted under the wing), the direction connecting the longitudinal direction of the lift and two mounting points on the aircraft (vertical of the aircraft wing) Direction, and the inconvenience of having to move the lift several times in order to position the lift in the correct mounting position.

The connection frame 220 is a pair that is spaced apart a predetermined interval, and has a rack gear and an interference prevention unit 221 for providing a left and right movement space of the pinion gear to move along the rack gear to be described later.

Hereinafter, the link mechanism will be described in more detail.

FIG. 5 is an enlarged perspective view of the link mechanism of FIG. 4.

As shown in FIGS. 4 and 5, the link mechanism 300 includes a drive link 310, a driven link 320, a gear means 330, and a tilting means 350.

The drive link 310 and the driven link 320 is a bar shape, respectively, and a pair of connecting the pedestal assembly 100 and the body assembly 200 side by side at a spaced apart from each other side by side and a parallelogram structure Have

One end of the driving link 310 is connected to the pedestal assembly 100 by the first shaft 311, and the other end is connected to the body assembly 200 by the second shaft (not shown). The driven link 320 has one end connected to the pedestal assembly 100 by a third shaft 321 and the other end connected to the body assembly 200 by a fourth shaft 323.

Substantially, the first shaft 311 of the drive link 310 and the third shaft 321 of the driven link 320 are connected to the support plate support frame 120 of the pedestal assembly 100. The second shaft of the drive link 310 and the fourth shaft 323 of the driven link 320 are connected to the connection frame 220 of the body assembly 200. The support plate support frame 120 and the connection frame 220 are positioned in parallel to each other.

Gear means 330 for rotating the second shaft is installed on the second shaft of the drive link (310). The gear unit 330 rotates the second shaft to rotate the drive link 310. When the drive link 310 is rotated, the driven link 320 is also rotated in conjunction with the pedestal assembly 100 can be raised and lowered relative to the body assembly 200. For example, when the second axis of the drive link 310 rotates clockwise, the pedestal assembly 100 descends relative to the body assembly 200, and when the second axis rotates counterclockwise, the pedestal assembly 100 Go up and down.

The gear means 330 includes a worm gear 331 and a worm 335 which are integrally installed on the second shaft of the drive link 310. The worm gear shaft 333 of the worm gear 331 is integrally connected to the second shaft of the drive link 310, and the worm 335 having a spiral shape is engaged with the worm gear 331 at right angles.

The worm gear shaft 333 of the worm gear 331 integrally installed on the second shaft of the drive link 310 may be integrally connected to the second shaft, and the worm gear shaft 333 may replace the second shaft. . Therefore, only the worm gear shaft 333 may be displayed without separately displaying the second shaft.

For reference, the state in which the worm gear shaft 333 is integrally connected to the second shaft may be confirmed in FIG. 8. The worm gear shaft 333 is a hollow shaft, and the second shaft is press-fitted into the hollow of the worm gear shaft 333 and connected integrally. A worm handle 337 capable of rotating the worm 335 is connected to the worm shaft 336 of the worm 335. When the worm handle 337 is gripped and rotated, the worm gear 331 meshing with the worm 335 rotates by rotating the spiral shape of the worm 335.

The worm 335 is rotatably installed so that both ends of the worm shaft 336 are supported by the gear support frame 340. One side of the gear support frame 340 is fixed to the connection frame 220. In addition, although not shown, the worm shaft 336 of the worm 335 may be installed on the gear support frame 340 to be rotatable by a bearing, a stop ring, or the like.

Tilting means 350 is provided to move the second axis left and right on the second axis of the drive link 310.

The tilting means 350 moves the second axis, which is the central axis of rotation of the driving link 310, to the left and right to tilt the pedestal assembly 100 to the body assembly 200. Since the worm gear shaft 333 is integrally connected to the second shaft, the tilting means 350 may be viewed as moving the worm gear shaft 333 left and right.

The tilting means 350 includes a pinion gear 351 which is integrally connected to the second shaft of the drive link 310 and a rack gear 357 that meshes with the pinion gear 351. The pinion shaft 353 of the pinion gear 351 is integrally connected to the second shaft of the drive link 310. Substantially, as shown in FIG. 6, without connecting the second shaft integrally with the pinion shaft 353, the second shaft becomes the pinion shaft 353 and the pinion shaft 353 of the worm gear shaft 333. It may be inserted through the hollow and connected integrally.

The pinion gear 351 is installed at one end of the pinion shaft 353. The pinion shaft 353 may engage with the rack gear 357 fixed to the body assembly 200 and move left and right. The rack gear 357 should be positioned parallel to the pedestal assembly 100 so that the second axis, that is, the pinion shaft 353, can move left and right only at the center of rotation, and thus the body assembly 200 is positioned parallel to the pedestal assembly 100. It is fixed to). Preferably, the pinion gear 351 and the rack gear 357 are positioned on the interference prevention part 221 of the connecting frame 220 so that the pinion gear 351 can be engaged with the rack gear 357 and move left and right. 357 is firmly fixed to the pinion support frame 370 installed on the connection frame 220.

In practice, the rack gear 357 is fixedly coupled to the connecting plate 370 ′ of the pinion support frame 370. The connecting plate 370 is a part of the pinion support frame 370, and the rack gear 357 is fixedly coupled to two front and rear portions of the connecting plate 370 ', respectively (see FIGS. 5 and 7).

The pinion support frame 370 is installed at both sides of the connection frame 220. Specifically, the pinion support frame 370 is installed on the connecting frame 220 corresponding to the position where the pinion shaft 353 is installed, and the long hole 371 through which the pinion shaft 353 passes is formed long to the left and right.

And a gripper 360 connected to the pinion shaft 353 to rotate the pinion gear 351.

The pinion shaft (or the second shaft) 353 is assembled through the long hole 371, and the holding unit 360 capable of rotating the pinion gear 351 to the pinion shaft 353 passing through the long hole 371 is provided. It is provided. That is, the gripper 360 is coupled to the end of the pinion shaft 353 through the long hole 371 of the pinion support frame 370 and exposed to the outside. An end portion of the pinion shaft 353 to which the gripper 360 is coupled may be provided with a groove that is formed in the gripper 360 to facilitate coupling of the gripper 360.

When the pinion shaft 353 is rotated by rotating the gripper 360, the pinion shaft 353 may move left and right by the rack gear 357 and the long hole 371. The length of the long hole 371 determines the amount of left and right movement of the pinion shaft 353, and consequently, the tilting angle may be limited to a certain range. For example, the tilting angle may be limited to a range of 0 to 10 ° and −20 ° to 20 ° according to the length of the long hole 371.

A male screw 355 is machined into the pinion shaft 353 passing through the long hole 371 of the pinion support frame 370 and a clutch 380 for locking or unlocking the rotation of the pinion gear 351 to the male screw 355. Is installed.

The clutch 380 is formed in a hollow cylindrical shape of which one side is opened, and may be composed of a metal and a friction pad attached to the metal. The clutch 380 has a female thread formed in the hollow portion and is screwed to the male thread 355 of the pinion shaft 353, and is selectively adhered to the friction surface 373 provided with the pinion support frame 370 by the rotation of the friction pad. It is possible to lock the rotation state of the pinion gear 351.

The friction surface 373 forms a part of the outer surface of the pinion support frame 370 to protrude in a curved shape, and the clutch 380 rotates so that the friction pad portion abuts against the friction surface 373 of the pinion support frame 370. When the pinion shaft 353 is not rotated, the pinion shaft 353 is fixed, and thus the clutch lock state is restricted. In addition, when the clutch 380 is rotated counterclockwise to release the friction pad part from being in close contact with the friction surface 373 of the pinion support frame 370, the grip part 360 may be removed by using an appropriate tool or by manpower. The pinion gear 351 may move left and right by rotating. In addition, when the pinion gear 351 is moved left and right, when the clutch 380 is locked at a specific position, the pinion shaft 353 is fixed without rotation. The clutch 380 is for preventing the pedestal gear 351 from tilting due to the arbitrary rotation of the pinion gear 351 due to the external attachment installed on the pedestal 160 or the weight of the link mechanism 300.

The lifting and tilting operation of the linkage mechanism will be described in detail.

The link mechanism 300 installs the worm 335 and the worm gear 331 on the right drive link 310 which rotates with respect to the lower body assembly 200, and rotates the worm handle 337 to rotate the worm 335. When rotated, the height of the link mechanism 300 is adjusted by the rotation of the worm gear 331 integrally installed in the drive link 310. The height-adjusted link mechanism 300 is fixed at the height-adjusted position without returning to the original position due to the characteristics of the worm 335 and the worm gear 331.

The tilting operation of the link mechanism 300 is performed by rotating the clutch 380 to release the rotation lock state of the pinion shaft 353 and then rotating the pinion shaft 353 with a tool or a manpower. When the pinion shaft 353 rotates, the pinion gear 351 is engaged with the rack gear 357 to move from side to side in the length range of the long hole 371 formed in the pinion support frame 370. As a result, the pinion shaft 353 By moving the center of rotation of the drive link 310, i.e., the second axis, left and right concentrically, the pedestal 160 is inclined (tilting) to the left or right with respect to the ground (or the bottom surface).

The operation of the gear means 330, the tilting means 350 may be performed manually or automatically by the power of the motor.

As shown in FIG. 7, in another embodiment, a gear means 330 for rotating the second shaft 313 on the second shaft 313 of the drive link 310 is installed, and the driven link 320 is formed of the driven means 320. Tilting means 350 for moving the fourth shaft 323 to the left and right on the four shaft 323 is installed.

The gear unit 330 rotates the second shaft 313 to rotate the drive link 310. When the drive link 310 is rotated, the driven link 320 is also rotated in conjunction with the pedestal assembly 100 can be raised and lowered relative to the body assembly 200.

The gear means 330 includes a worm gear 331 and a worm 335 which are integrally installed on the second shaft 313 of the drive link 310. The worm gear shaft 333 of the worm gear 331 is integrally connected to the second shaft 313 of the drive link 310, and the worm 335 having a spiral shape is orthogonal to the worm gear 331. To interlock.

The worm gear shaft 333 is a hollow shaft and the second shaft 313 is inserted into the hollow of the worm gear shaft 333 is connected integrally. A worm handle 337 capable of rotating the worm 335 is connected to the worm shaft 336 of the worm 335. When the worm handle 337 is gripped and rotated, the worm gear 331 meshing with the worm 335 rotates by rotating the spiral shape of the worm 335.

The worm 335 is rotatably installed so that both ends of the worm shaft 336 are supported by the gear support frame 340. One side of the gear support frame 340 is fixed to the connection frame 220.

The tilting means 350 moves the fourth shaft 323, which is a rotation center axis, to the left and right to enable tilting of the pedestal assembly 100 to the left and right of the body assembly 200. Since the pinion shaft 353 is integrally connected to the fourth shaft 323, the tilting means 350 may move the pinion shaft 353 to the left and right.

The tilting means 350 includes a pinion gear 351 integrally connected to the fourth shaft 323 of the driven link 320 and a rack gear 357 engaged with the pinion gear 351. The pinion shaft 353 of the pinion gear 351 is integrally connected to the fourth shaft 323 of the driven link 320. The fourth shaft 323 may be the pinion shaft 353 without substantially connecting the fourth shaft 323 integrally with the pinion shaft 353.

The pinion gear 351 is installed at one end of the pinion shaft 353. The pinion gear 351 may be engaged with the rack gear 357 fixed to the body assembly 200 to move left and right. The rack gear 357 should be positioned in parallel with the pedestal assembly 100 so that the fourth axis, that is, the pinion shaft 353 can move left and right only at the center of rotation, and thus the body assembly 200 is positioned in parallel with the pedestal assembly 100. It is fixed to). Preferably, the pinion gear 351 and the rack gear 357 are the interference prevention part 221 of the connecting frame 220 of the body assembly 200 such that the pinion gear 351 may be engaged with the rack gear 357 and move left and right. Located in the rack gear 357 is firmly fixed to the pinion support frame 370 installed in the connecting frame 220.

The pinion support frame 370 is installed at both sides of the connection frame 220. Specifically, the pinion support frame 370 is installed on the connecting frame 220 corresponding to the position where the pinion shaft 353 is installed, and the long hole 371 through which the pinion shaft 353 passes is formed long to the left and right.

And a gripper 360 connected to the pinion shaft 353 to rotate the pinion gear 351.

The pinion shaft (or fourth shaft) 353 is assembled through the long hole 371, and the grip portion 360 capable of rotating the pinion gear 351 to the pinion shaft 353 through the long hole 371 is provided. It is provided. That is, the gripper 360 is coupled to the end of the pinion shaft 353 through the long hole 371 of the pinion support frame 370 and exposed to the outside. An end portion of the pinion shaft 353 to which the gripper 360 is coupled may be provided with a groove that is formed in the gripper 360 to facilitate coupling of the gripper 360.

When the pinion shaft 353 is rotated by rotating the gripper 360, the pinion shaft 353 may move left and right by the rack gear 357 and the long hole 371. The length of the long hole 371 determines the amount of left and right movement of the pinion shaft 353, and consequently, the tilting angle may be limited to a certain range. For example, the tilting angle of the pedestal assembly 100 may be limited to a range of 0 to 10 ° and −20 ° to 20 ° depending on the length of the long hole.

A male screw 355 is machined into the pinion shaft 353 passing through the long hole 371 of the pinion support frame 370 and a clutch 380 for locking or unlocking the rotation of the pinion gear 351 to the male screw 355. Is installed.

The clutch 380 is formed in a hollow cylindrical shape of which one side is opened, and may be composed of a metal and a friction pad attached to the metal. The clutch 380 has a female thread formed in the hollow portion and is screwed to the male thread 355 of the pinion shaft 353, and is selectively adhered to the friction surface 373 provided with the pinion support frame 370 by the rotation of the friction pad. It is possible to lock the rotation state of the pinion gear 351.

The friction surface 373 forms a part of the outer surface of the pinion support frame 370 to protrude in a curved shape, and the clutch 380 rotates so that the friction pad portion abuts against the friction surface 373 of the pinion support frame 370. When the pinion shaft 353 is not rotated, the pinion shaft 353 is fixed, and thus the clutch lock state is restricted. In addition, by rotating the clutch 380 to release the friction pad portion in close contact with the friction surface 373 of the pinion support frame 370, the pinion gear may be rotated by using an appropriate tool or by rotating the grip 360 by an attractive force. 351 may move left and right. In addition, when the pinion gear 351 is moved left and right, when the clutch 380 is locked at a specific position, the pinion shaft 353 is fixed without rotation. The clutch 380 is for preventing the pedestal gear 351 from tilting due to the arbitrary rotation of the pinion gear 351 due to the external attachment installed on the pedestal 160 or the weight of the link mechanism 300.

In another embodiment described above, the worm 335 and the worm gear 331 for installing the lifting function of the pedestal assembly 100 in the drive link 310 is installed, and the tilting function is implemented in the driven link 320 The pinion gear 351, the rack gear 357, and the clutch 380 are installed. In other embodiments, the front, rear, left and right functions of the pedestal 160 are equally applicable.

At this time, the mounting device should be adjusted to the minimum height so that interference or collision with the structure under the wing of the aircraft does not occur. Thereafter, when the worm handle 337 is rotated to raise the pedestal assembly 100 of the mounting apparatus 10 to an appropriate height, and the grip portion 360 is rotated after the clutch 380 is unlocked, the aircraft is viewed from the side. By adjusting the pedestal assembly 100 left and right inclined by the left and right inclined angles of the aircraft wing, the female-male connector connection work and the mechanical coupling device coupling work of the mounting are performed.

At this time, the conventional lift device has been inconvenient to adjust the exact coupling position between the external mounting and the aircraft by moving the entire lift device when the lift device is not placed in the correct coupling position between the external mounting and the aircraft, in the case of the present embodiment Without moving the entire mounting apparatus 10, it is possible to adjust the exact engagement position through the lifting and lowering, tilting function and the like.

As described above, in the embodiment of the present invention, when installing the external attachment to the aircraft wing, the position of the pedestal 160 may be adjusted back and forth, left and right, so that the external attachment may be more smoothly mounted to the aircraft.

In addition, the mounting interval between the pedestal 160 for mounting the external mounting is also adjustable, it is possible to install a variety of external mounting on the aircraft. In addition, it replaces a mechanical device such as a worm and a pinion as compared with a conventional large, heavy lifting device for external mounting, and replaces an aircraft external mounting device having a lifting (lifting) and tilting (adjustment of left and right tilt) function in a small size. In addition to the application of external attachments to the aircraft, it can be applied to various applications requiring lifting and tilting functions.
