The present invention relates to a roller conveyor having a roller support member for determining the position of the roller seated on the upper surface of the main body frame, in particular, the disaster relief proximity of the disaster prevention agency, forestry and police offices, the proximity of the disaster relief material, troops, supplies, equipment Since the tactical airlift of various tasks to carry out a variety of tasks for the cargo itself can not be modified, the roller conveyor can be used only for cargo release.

In the event of disaster relief, two to four people are on board depending on the weight (45 ~ 226kg) and volume of cargo in addition to the crew of close-up, air-drop supply and various cargo releases. Loading and dropping are limited. Therefore, the increase in the number of operations of a large amount of cargo release, the time is long, and the aviation budget is excessive.

In addition, since the cargo is released by manpower (type pushed out of the body door), the weight of the cargo impacts the fuselage of the aircraft, there is a risk of aviation accidents.

Dropping cargo by parachute There is a risk of aircraft accidents because the cargo rotates and the cargo is entangled with the parachute or the parachute is malfunctioning.

As shown in FIG. 13, the UH-60 class aircraft exhibits a departure form of cargo upon cargo release.

As shown in Fig. 13 (a), when the cargo is discharged when the cargo exits 1/3, the gas door is rotated out of the axis because the center of gravity is located upward. Therefore, the impact on the lower end of the body. In addition, the parachute is located at the lower end of the cargo, causing the parachute square to flip.

As shown in Fig. 13 (b) and Fig. 13 (c), when the cargo drops at 1/2 and 2/3 to the gas door, it descends vertically at the gas door, but the parachute is at the top of the cargo This may result in cargo falling as it is, such as parachute tangles or parachute spreading.

Similarly, as shown in Figs. 14 (a) to 14 (c), if a UH-1H aircraft is used in case of emergency, the skid protrudes from the fuselage cargo compartment when the UH-1H aircraft is dropped. There is a risk of serious breakage and fall in the fuselage, and the cargo may be rotated irregularly, causing parachute failure.

When the C-130 and CN-235 aircraft fuselage doors are released, the cargo may impact the fuselage, causing damage to the fuselage or malfunction of the cargo parachute.

Thus, due to the risk of damage to the fuselage due to cargo dropping and the loading of a small number of supplies due to the large number of passengers, the time required for the dropping supply becomes long, which hinders special operations.

As the time required for the drop replenishment operation is long, the aircraft has a lot of exposure time, so the risk of sniper is very high.

In addition, the CH-47 rotary wing aircraft has limited maneuvering due to maneuvering during small-scale sea penetration and delayed time delays and the inversion of equipment due to back storms.

On the other hand, as a conventional roller conveyor, for example, the one disclosed in Korean Laid-Open Utility Model No. 1986-10714 is proposed. As shown in Fig. 15, the conventional roller conveyor has a frame 3 so as to be able to walk and support the shaft 2 of the roller 1 in extending several rollers 1 between the " (3 ') Several hook pieces (4) having grooves (5) formed on their own are punched out at regular intervals to protrude.

By the way, if the position of the roller 1 is to be changed, the shaft 2 should be taken out in the groove 5 and then put in the groove 5 of the other hook piece 4.

Therefore, since the position of the roller 1 is determined by the position of the hook piece 4, minute adjustment is difficult.

In addition, when the weight of the roller is a lot of weight is difficult to lift and move to the hook piece of another position.

The present invention was devised to solve the above-mentioned problem, and it is easy to change the position of the roller regardless of the weight of the roller, and to block the collision and jamming with the aircraft during the cargo release, thereby loading the cargo during the airdrop replenishment using the rotorcraft. Its purpose is to provide a roller conveyor that can reduce operational time and ensure the safety of aircraft, crew and personnel.

The roller conveyor of the present invention for achieving the above object has a main frame having a pair of side frames, a plurality of rollers disposed between the two side frames, and the roller shaft of the rollers on the upper surface of the side frame. It comprises a roller shaft support member for supporting.

According to this configuration, it is not only easy to change the position of the roller regardless of the weight of the roller, but also to block collisions and jams with the aircraft during cargo release, thereby shortening the operation time by quickly and smoothly discharging the cargo during air supply using a rotorcraft. To ensure the safety of the aircraft, crew and release personnel.

In the above-described configuration, the roller shaft support member is composed of a foot base formed with a shaft receiving groove for receiving the roller shaft, and a binding member for binding the foot base to the side frame,

The binding member is preferably composed of a spring nut movably mounted along the guide groove formed in the side frame, and a bolt that is fastened to the spring nut to bind the footbase to the top surface of the side frame.

In addition, the roller shaft is preferably provided with a flange disposed in the guide groove, the foot base is preferably formed with a flange receiving groove for receiving the flange.

In addition, the eye bolt is preferably fastened to the side frame.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, the rotorcraft aircraft, it will be apparent to those skilled in the art that it can be used to attach or detach from a fixed-wing aircraft or elsewhere.

1 and 2, the cargo discharging conveyor system 1 of the rotary wing aircraft according to the present embodiment is a cargo conveyor roller conveyor 100 in one gas door (for example, the left gas door) of the aircraft Batch is installed.

Since the dropping roller conveyor 100 is installed in the gas door, when the cargo G is put up and pushed, the cargo is speeded up by the rolling motion, and the cargo is lowered horizontally by inertia and then lowered vertically.

By this dropping form, the collision with the fuselage due to the rotation of the cargo is eliminated, and the parachute P of the cargo is at the upper end, and the phenomenon in which the parachute is not entangled or spread can be blocked. (See Figures 7 and 8)

Therefore, it is possible to shorten the operation time by quickly and smoothly dropping cargo when supplying airdrops using a rotorcraft, and to perform missions even if the number of dropouts is reduced to the maximum. In addition, it can minimize the air vehicle exposure time.

As shown in FIGS. 1 to 3, the drop roller conveyor 100 includes a plurality of main body frames 110 having a pair of side frames 111 and a plurality of side frames 111. The roller 130 of the roller 130 and the roller shaft support member 150 which supports the roller shaft 131 of the roller 130 to the upper surface 112 of the side frame 111 are comprised.

Since the roller shaft 131 is placed and supported on the upper surface 112 of the side frame 111, when the position of the roller 130 is to be changed, the roller shaft supporting member 150 is disassembled and the roller 130 is pushed. By rolling (as if a train is moving on a rail), no matter how heavy it is, you can support it exactly where you want it.

On the other hand, the main frame 110 is provided with a connection frame 113, 114 for connecting both side frames 111. The connecting frames 113 and 114 serve to firmly maintain the gap between the side frames 111.

In addition, the main body frame 110 is preferably implemented in an aluminum profile formed with guide grooves 115, 116, 117, 118 on four surfaces, in terms of assembly disassembly.

In addition, the end caps 240 are preferably installed at the end portions of the guide grooves 115, 116, 117, 118 as shown in FIG. 10. It is preferable that the end cap 240 has an entrance hole through which the long nut portions 250a and 250b enter and exit. In addition, the guide grooves 115, 116, 117, 118 is preferably sealed with a sealing band (black portion) except for the sliding section of the long nut.

In particular, in the case of the dropping roller conveyor 100, it is preferable to arrange the free end roller 140 on the side frame 111 with the connection frame 114.

That is, the free end roller 140 may leave the drop roller conveyor 100 to further secure the inertial force of horizontal movement and vertical descent, thereby blocking the collision with the fuselage or the change of the position of the parachute.

The roller 130 or 140 is comprised by the roller shaft 131 and the roller main body 133 rotatably provided in this roller shaft 131. As shown in FIG.

The lower surface of the foot base 160 is formed with a bearing groove 161 for receiving the roller shaft 131.

The binding member 170 includes a fastening hole 171 formed in the foot base 160, a spring nut 173 mounted on the guide groove 115, and the spring nut 173 through the fastening hole 171. It consists of a screw 175 is fastened with.

When fastening the screw 175, it is preferable to fasten after applying an adhesive to prevent loosening due to shaking of the aircraft. In this case, it can also be disassembled by hand.

The spring nut 173 is comprised from the nut 173a and the elastic piece 173b which applies an elastic force to this nut 173a upward.

That is, one end of the elastic piece 173b is fixed to the bottom surface of the nut 173a, the other end is supported by the bottom of the guide groove 115, and one end and the other end of the nut 173a are inclinedly connected.

Due to this configuration, the upper surface of the nut 173a is continuously caught by the upper locking jaw 115a of the guide groove 115 and receives the elastic force.

Accordingly, the spring nut 173 is not only easily detachable from the guide groove 115 and / or from the guide groove 115, but also closely adheres to the guide groove 115 to firmly determine the fastening position with the foot base 160.

On the other hand, it is preferable that the flange 135 is provided in the roller shaft 131.

The flange 135 is preferably accommodated in the flange receiving groove 165 formed on the lower surface of the foot base 160.

Therefore, the upper portion of the flange 135 is disposed in the flange receiving groove 165, and the lower portion is disposed in the upper opening 115b of the guide groove 115, to secure the position fixing in the longitudinal direction of the rollers 130, 140. You can actually do it.

The fastening screw hole 166 is preferably formed at the center portion of the foot base 160 or at the position where the flange receiving groove 165 is located.

When the bolt bolt 167 without the head is fastened to the fastening screw hole 166, the lower end of the mood bolt 167 functions to hold the upper surface of the flange 135.

Therefore, the rolling motion of the roller body 133 is very excellent by the firm and reliable fixation of the roller shaft 131.

In particular, when the outer circumferential surface of the flange 135 has a hexagonal shape, the lower end of the mood bolt 167 can widen the contact area for pressing the flange 135, it is possible to more securely fix.

On the other hand, it is preferable that the eye bolt 180 that is a fixing member is fastened to the inner guide groove 116 of the side frame 111.

The auxiliary moving roller conveyor 300b 'is coupled by the hinge 190 behind the front and rear moving roller conveyor 300a'.

As such, after the conveyor system is arranged in the shape of a cross on the bottom of the aircraft, the eye bolts 180 and the aircraft bottom loop of each conveyor are fastened by using the binding belt.

Then load the cargo.

The parachute lifeline is joined to the cargo in the order of dropping.

Tighten the cargo with strings (80 pound webbing).

The drop roller conveyor 100 (100 ') is folded (see FIG. 12) and then fixed (80 pound webbing).

Close the aircraft door and take off to open it at the airborne point.

The roller rollers 100 and 100 'are straightened horizontally and reinforce fixed / strength using left and right fasteners (such as long nuts).

After cutting the cargo tie, check the release point and release it, and collect the lifeline.

Depending on the number of cargoes, cut the cargo tie and then release and repeat the lifeline recovery.

The delivery roller conveyors 100 and 100 'are folded and the gas door is closed. Dismantling is carried out in reverse order of coupling.

When dismantling, the conveyors in the front and rear directions can be folded and stored in one bag, and the conveyors in the left and right directions can be separated and stored in another bag.

The roller conveyor of the present invention is not limited to the above-described embodiments and can be carried out in various modifications within the range permitted by the technical idea of the present invention. For example, the auxiliary moving roller conveyors 300, 300 ', 400, 400' can be used as a dropping conveyor by mounting the ball transfer 230 to the connecting frame.

In addition, the conveyor of the present embodiment can be used by reinforcing in a large aircraft.

To ensure the safety of the aircraft, the safety of the crew and the discharge personnel.

It shortens the time required for close-up, air-drop, and cargo release of goods during disaster relief, minimizing the exposure time of the aircraft at the enemy site, reducing the risk of sniper, and contributing to privileged unit operations by being able to drop at the exact target point. .

Significantly shorter aircraft airtime can save airline budgets.

A single cargo dropper can also be used to free up space for cargo loading.

Foldable or detachable between conveyors allows portable storage, so it can be applied to other rotorcraft by attaching and detaching to the bottom of the aircraft.

Since the roller is supported on the upper side of the side frame, the roller shaft support member can be disassembled and the roller can be changed by pushing the roller to the desired position. easy.

Further, by arranging the rollers further at the free end of the dropping roller conveyor, the horizontal movement and vertical dropping of the cargo can be performed more reliably, and entanglement or scattering (not spreading) due to collision with the fuselage or overturning of the parachute is prevented. It is possible to block the safety accidents of the back.

In addition, since the eye bolt is installed in the side frame, it is convenient to engage with the hook of the bottom of the aircraft.

When the cargo ship is operated with the CH-47 rotorcraft, the cargo extractor (conveyor device) that calculates the speed of movement of the aircraft is released precisely, and the rapid release and departure during small sea penetration (R / D, S / D) This can minimize equipment upset and damage.
