FIG.

1 to 4, the helicopter takeoff assistance device of the present invention includes a plurality of gear boxes 100, a plurality of wheel fixing frames 200, and a wheel fixing portion 300.

The plurality of gear boxes 100 are arranged at equal intervals along the rim of the helideck 20 so as to correspond to the number of the wheels 11 of the helicopter 10. The cable 400 is wound, Forced locking is applied when applied.

The forcible locking in the present invention is a normal safety belt that is driven by an inertial force generated when a cable 400 is suddenly displaced or by a centrifugal force so that the stop ring, Of the present invention.

The plurality of wheel fixing frames 200 are connected to the cables 400 of the plurality of gear boxes 100 and each of the wheels 11 is accommodated.

Referring to FIG. 4, a wheel fixing part 300 according to the present invention is installed in each of a plurality of wheel fixing frames 200.

The wheel fixing part 300 fixes each of the wheels 11 through the pulling action of the fixing belt 310 and releases the fixed state of the fixing belt 310 by receiving a release signal from the outside.

More specifically, the wheel fixing part 300 includes a fixing belt 310 having one end fixed to the wheel fixing frame 200 and having a predetermined length and surrounding an upper end of the wheel 11, A winding member 320 formed at the other end of the rotating shaft 321 and formed with a rotating shaft 321 for winding the other end of the fixed belt 310; A ratchet gear 330 installed at a side portion of the rotary shaft 321 and rotated in conjunction with rotation of the rotary shaft 321 and having a plurality of gear teeth formed on one side thereof with an engagement surface 331 formed on the outer periphery thereof, A locking member 340 which is installed to rotate in the vicinity of the rotation shaft 321 and which has the other end engaged with one of the engagement surfaces 331 of the plurality of gears to regulate the rotation of the rotation shaft 321, The locking member 340 is rotated to maintain or regulate the state of the rotation shaft 321 And a rotator 350 for controlling the rotation.

The cable 400 includes a first cable 410 connected to the lower end of the wheel fixing frame 200 and a second cable 420 connected to the gear box 100, 410 and the second cable 420 are connected to each other by an emergency separator 500 that connects or disconnects the first cable 410 and the second cable 420 by receiving a separation signal from the outside.

At the upper end of the second cable 420, a damper 600 connected to the emergency separation device 500 and absorbing an external impact is installed.

The wheel fixing frame 200 is made of reinforced plastic and is surrounded by a protective film made of a sponge material.

The following describes a helicopter takeoff assistant method using the helicopter takeoff assistance device configured as described above.

FIG. 5 is a view showing a state of a helicopter takeoff assistance device in a state where a helicopter is taken off from the helideck, and FIG. 6 is a view showing a state in which the wheel fixing portion is unlocked according to the present invention.

Referring to FIGS. 4 and 5, three wheels 11 installed on the body of the helicopter 10 are fitted and fixed to the wheel fixing frames 200, respectively.

The wheel fixing part 300 installed on each wheel fixing frame 200 tightens the fixing belt 310 to fix the wheel 11 so that it can not move.

At this time, the cable 410 connects the gear box 100 and the wheel fixing frame 200.

6, when the helicopter 10 is taken off at a predetermined height, the helicopter 10 rotates the wheel fixing part 300 mounted on each wheel fixing frame 200 using a transmitter (not shown) And transmits a fix release signal to a receiver (not shown).

Each receiver receives the release signal and uses the rotary device 350 to rotate the locking member 240 hooked on the latching surface 331 of the ratchet gear 330 to release the latching state.

Therefore, the fixed belt 310 is released to release the fixed state of the wheel 11. [

At this time, in the present invention, since a sudden movement occurs and an impact may be applied to the helicopter when the locking function is driven, a damper 600 is added to the take-off assistance device to absorb the sudden impact.

In addition, the way to send a signal from the ship to the take-off assistant can be either wirelessly via the wireless remote control or via wired remote control.

In addition, as described above, the helicopter 10 can also transmit a signal wirelessly in an emergency.

The internal battery can also supply the power required by the actuator of the take-off assistant. Here, the battery may be replaced with a battery that is sometimes charged with a detachable battery or may be charged from time to time via a wired line equipped with an internal battery.

Further, the portion of the wheel fixing frame 200 of the take-off assistance device is made of a light and elastic material, such as reinforced plastic, so as to prevent the wheel fixing frame 200 from being damaged when it is dropped on the helideck 20.

7 is a view showing a state in which the first and second cables are separated by the emergency separating apparatus according to the present invention.

7, when the take-off assisting device is not operated and the cable 400 is not disconnected, a separation signal is generated and the cable 400 is disconnected or disconnected arbitrarily through the emergency separation device 500 .

Here, the emergency separation apparatus 500 may be a detachment device such as an electromagnet or a device for forcibly cutting a cable using a cutting blade.

A method of sending a signal from the ship to the emergency separation device 500 can be wirelessly received through a wireless remote control, or a signal can be transmitted via a wired remote control via a wired line.

In addition, the helicopter 10 can transmit a signal wirelessly in an emergency.

The internal battery supplies power to the actuator of the take-off assist device. The battery can be replaced with a battery that is sometimes replaced with a detachable battery, or it is charged from time to time via a built-in battery.

Also, when disconnecting or cutting the cable, it is better to loosen the cable and operate it because it can be more dangerous by the reaction force when the cable is suddenly disconnected.

In the present invention, when the take-off assistance device is detached, the impact is applied when the take-off assist device is dropped directly on the helideck by allowing the take-off assistance device to wrap the sponge- And damage to the helideck can be minimized.

Through the above-described structure and operation, the embodiment of the present invention can safely take off and land the helicopter even in extreme environments by using a detachable cable connecting the three wheels of the helicopter in the helideck.

In addition, in the embodiment according to the present invention, a cable capable of attaching / detaching three pieces to / from the lower portion of the helicopter is installed to suppress sudden movements such as yaw, pitch, and roll that can occur when the helicopter is taken off, .

As described above, the helicopter take-off assistance device and the helicopter take-off assistance method using the same have been described.

Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by the scope of the appended claims and equivalents thereof.

It is to be understood that the foregoing embodiments are illustrative and not restrictive in all respects and that the scope of the present invention is indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
