Description

The present invention relates to a transport stand for mounting a helicopter on a loading platform or the like, which is used when the helicopter is transported by a trailer or the like.

A medium-sized manned helicopter has a cruising range of several hundred kilometers and can move on its own within that range, but if it exceeds that range, it will need to be transported by a transport vehicle such as a trailer.

As shown in FIGS. 1 and 2, the manned helicopter incorporates a main shaft 2 that is rotationally driven by an engine (not shown), a main rotor 1 that is fixed to the main shaft 2, an engine, operating equipment, a seat, and the like. It includes a main body 3 to be used, a tail boom 6 extending rearward from the main body 3, and a landing gear 7 attached to the back surface of the main body 3. A tail rotor 4 and a horizontal stabilizer 5 are attached to the tail boom 6.

The landing gear 7 is a device for takeoff and landing. It has a lightweight and simple structure with a pair of parallel support skids 7a and 7b, and is safe for landing in poor conditions (soft ground, some rough terrain, etc.). Can be handled.

Since a helicopter having a skid has no wheels and cannot be towed and moved as it is, the helicopter is moved to an airfield hangar or the like by attaching wheels to the skid and towing it with a dedicated towing vehicle.

Further, there are not many examples of transporting a helicopter on a vehicle for a manned helicopter, but various conventional examples (Patent Documents 1 to 3) are shown for an unmanned helicopter for aerial spraying of pesticides and crop seeds. ..

Patent Document 1 shows a freight vehicle having a loading platform behind the driver's seat, and an in-vehicle auxiliary tool for transporting an unmanned helicopter and related equipment mounted on the loading platform. It is installed on the driver's side. In addition, a helicopter on which an equipment storage box having a height of the rear window of the driver's seat or a height exceeding this and a leg of an unmanned helicopter installed close to the loading platform surface at the rear of the passenger seat side of the loading platform are placed. An in-vehicle auxiliary tool for carrying an unmanned helicopter equipped with a mounting table is shown.

According to the above configuration, an unmanned helicopter and related equipment can be easily and compactly loaded on the loading platform of a freight vehicle, and it is possible to prevent obstruction of visibility that hinders driving.

Patent Document 2 describes two front and rear horizontal members having legs mounted on a loading platform of a vehicle such as a light truck, and horizontal fixing portions arranged at both ends of the horizontal members and in contact with the side wall portions of the loading platform. And the left and right two support members, which are spread over the two horizontal members and on which the left and right skids of the industrial unmanned helicopter are placed, respectively, and the left and right skids, which are arranged on the left and right two support members, respectively, are placed on the left and right skids. An in-vehicle fixture for an industrial unmanned helicopter with a skid anchor that secures to two support members is shown.

According to the above configuration, the in-vehicle fixture has a simple structure that can be disassembled and easily carried, and it is easy to handle by easily attaching and detaching it to the loading platform of a vehicle such as a light truck. However, it can be handled and has excellent versatility, the work of loading and unloading the unmanned helicopter is easy, the fixing workability is excellent, and the unmanned helicopter can be firmly held and transported to the destination.

Patent Document 3 describes a removable rudder rail for loading and unloading a cart having at least a pair of wheels for transporting an unmanned helicopter in a transport vehicle, and a cart stand fixed to a loading platform on which the cart can be placed. An in-vehicle device for transporting an unmanned helicopter is shown.

In Patent Document 1, an unmanned helicopter can be easily loaded compactly on the loading platform of a freight vehicle in a tilted state, and it is possible to prevent obstruction of the field of view that hinders driving.

However, the manned helicopter is heavy and the support portion is overloaded, which may damage the body. For this reason, in a manned helicopter, the parts that support the load are parts with high mechanical strength such as the shaft of the main rotor, the shaft of the horizontal stabilizer, and the fixed part of the landing gear, where the force concentrates during flight and landing. It is supposed to be.

In Patent Document 2, an unmanned helicopter is mounted on a vehicle via a skid, and in Patent Document 3, an unmanned helicopter is mounted on a vehicle via its support legs and a cart. In any case, in these patent documents, the unmanned helicopter is placed on the loading platform of the vehicle via the landing gear.

However, applying this to a manned helicopter causes the following problems. As shown in FIGS. 1 and 2, the vehicle that can be mounted is a trailer due to the size of the manned helicopter. When the helicopter is placed on the loading platform via the landing gear as shown in Patent Documents 2 and 3, the state shown in FIGS. 22 and 23 is obtained.

At the time of mounting, the helicopter is lifted by a crane (not shown) on the main shaft from which the main rotor is removed, and is hung on the loading platform 101 of the trailer 100 in a substantially horizontal state as shown in FIG.

By lifting the helicopter on the main shaft, the helicopter can be lifted in the same state as during flight, and the overall weight can be balanced and stabilized in an almost horizontal state.

As shown in FIG. 23, the manned helicopter is mounted on the loading platform 101 of the trailer 100 with the main rotor 1 and the tail rotor 4 removed and the main body 3, the tail boom 6 and the landing gear 7 provided.

A medium-sized manned helicopter with a passenger capacity of about 15 has dimensions of about 11 to 13 m in length (main body 3, tail boom 6) and a height (main rotor, main body, landing gear) of about 3. It is .2 to 4.6 m.

On the other hand, the dimensions of a vehicle that can travel on public roads (including loads) are 12 m in length and 3.8 in height.

Therefore, in the state of FIG. 23, the size of the vehicle (including the load) exceeds the size capable of traveling on public roads. And a car) will be required, and the transportation cost will be significantly higher.

It is necessary to reduce the mounting height and length of the helicopter in order to make it sized to run on public roads. Since the helicopter has a structure in which the main body 3 and the tail boom 6 can be separated, it is considered effective to separate the tail boom 6 from the main body 3 in order to reduce the length of the helicopter.

However, since the center of gravity of the main body 3 from which the tail boom 6 is separated moves to the front side, the posture tends to be large and forward when the main body 3 is lifted by the main shaft 2. If the main body 3 is hung on the trailer 100 in the forward leaning posture, the main body 3 may first come into contact with the loading platform 101.

Since the main body 3 has an engine, operating equipment, seats, etc. built-in, it occupies most of the total weight of the helicopter, and if it first comes into contact with the loading platform 101 when it is hung, there is a high risk of damage due to that weight. ..

This situation is the same when unloading (the main body 3 is lifted from the loading platform 101 and hung on the ground). When the main body 3 in the mounted state is lifted from the loading platform 101, the main body 3 contacts the loading platform 101 to the end, and when the main body 3 first contacts the ground when suspending from the ground, the main body 3 is damaged. There is a great deal of fear.

Further, in order to reduce the mounting height of the helicopter, it is conceivable to interpose a low-height support between the main body 3 and the loading platform.

In the present invention, the above-mentioned defects of the prior art are considered, and the dimensions of the transport vehicle and the helicopter are suppressed to the dimensions that allow the helicopter to travel on public roads, and an unreasonable load is applied to the main body when the helicopter is loaded and unloaded on the transport vehicle. It is an object of the present invention to provide a helicopter transport stand that prevents such a situation.

The present invention that achieves the above object is fixed in place of the landing gear of a helicopter consisting of a main body having a main rotor that rotates about a main shaft, a tail boom, and a landing gear fixed to the main body. A helicopter transport mount that supports the body on the loading platform of the transport vehicle.

According to this configuration, since the main body with the tail boom removed is mounted on the loading platform of the transport vehicle, the mounting length of the helicopter can be shortened.

Further, according to this configuration, when the main body is lifted from the main shaft, the extension portion protruding forward of the transport stand is located below the lowermost end of the main body, so that when the main body is lifted from the loading platform of the transport vehicle, the extension portion is located below the lowermost end of the main body. When hanging on the ground or on the ground, the extension portion comes into contact with the loading platform or the ground to avoid contact with the main body, so that there is no risk of damaging the main body.

Further, in the above, the front mounting portion and the rear mounting portion are each set lower than the height of the landing gear.

According to this configuration, since the helicopter is mounted via a transport frame having a height lower than that of the landing gear, the mounting height of the helicopter can be lowered.

Further, in the above, the front mounting portion has front legs fixed to the front lateral frame at a predetermined height, and the rear mounting portion has rear legs fixed to the rear lateral frame at a predetermined height. The front leg is characterized in that an inclined portion is formed at a corner with the front mounting portion.

According to this configuration, when fixing the front mounting portion to the helicopter, it is possible to avoid the wiring or accessories extending from the helicopter from being pinched by the inclined portion.

Further, in the above, the rear horizontal frame is movably connected to the two vertical frames in the front-rear direction.

According to this configuration, even if the distance between the front fixing portion and the rear fixing portion is slightly different depending on the helicopter, it can be adjusted by moving the rear lateral frame.

Further, in the above, the vertical frame, the combination unit of the front horizontal frame and the front mounting portion, the combination unit of the rear horizontal frame and the rear mounting portion, the unit of the front reinforcing frame, and the unit of the central reinforcing frame can be disassembled. It is characterized by being composed.

According to this configuration, by disassembling the transport stand into units that are easy to carry and easy to assemble, it is possible to easily carry and assemble the helicopter into a storage warehouse or the like.

According to the present invention, the total dimensions of the transport vehicle and the helicopter can be kept small to a length and height that can travel on public roads, and an unreasonable load is applied to the main body when the helicopter is loaded and unloaded on the transport vehicle. Can be prevented.

FIG. 3 is an explanatory diagram of an outline of an embodiment of the present invention. In this embodiment, the landing gear 7 is removed from the fixed portion (described later) on the back surface of the main body 3 of the helicopter, and the transport stand 20 is fixed to the fixed portion instead. This work is performed in a state where the helicopter is lifted by a crane or the like (not shown) on the main shaft 2.

FIG. 4 is a perspective view of a helicopter transport stand according to an embodiment of the present invention, FIG. 5 is a plan view, and FIG. 6 is a side view. In FIGS. 4 to 6, reference numeral 21 denotes two parallel vertical frames made of a U-shaped steel material. Reference numeral 22 denotes a front horizontal frame orthogonal to the front of the parallel vertical frame 21 and fixed by screwing, and 23 is a rear horizontal frame orthogonal to the rear of the parallel vertical frame 21 and fixed by screwing. The front and rear lateral frames 22 and 23 are made of prismatic steel.

The mounting holes for the rear horizontal frame 23 of the vertical frame 21 are formed in elongated holes, and are screwed so as to be movable in the direction of arrows along the elongated holes. As a result, even if there is a slight error in the distance between the fixing portions on the back surface of the main body 3, the transportation frame 20 can be reliably fixed by adjusting the movement of the mounting position of the rear lateral frame 23.

Reference numeral 24 denotes a front mounting portion made of a round pipe steel material fixed on the front horizontal frame 22 at a predetermined height. The front mounting portion 24 is set to a height L1 from the bottom of the vertical frame 21.
Reference numeral 25 denotes a rear mounting portion made of a round pipe steel material, which is fixed on the rear lateral frame 23 at a predetermined height lower than that of the front mounting portion 24.

The front mounting portion 24 has two front legs 28 having a predetermined height fixed to the front lateral frame 22 on both sides, and the rear mounting portion 25 has two front legs having both sides fixed to the rear lateral frame 23. It has 30 hind legs. Both the front legs 28 and the rear legs 30 are made of prismatic steel, and the height dimension of the front legs 28 is set higher than that of the rear legs 30.

The front mounting portion 24 and the rear mounting portion 25 are mounted on the front fixing portion and the rear fixing portion (both described later) on the back surface of the main body 3 of the helicopter, respectively.

The front mounting portion 24 and the rear mounting portion 25 are set to a height dimension lower than the height before and after the landing gear 7 removed from the helicopter. With this configuration, the mounting height of the helicopter on the loading platform of the transport vehicle is made as low as possible.

Each front leg 28 is formed with an inclined portion 29 at a corner connected to the front mounting portion 24. The inclined portion 29 can be avoided so as not to pinch the wiring or accessories extending from the helicopter when fixing the front mounting portion 24 to the back surface of the main body 3.

Reference numeral 26 denotes an extension portion formed so that the front end of each vertical frame 21 protrudes forward by a predetermined length L, and 36 is the tip of the extension portion. Reference numeral 27 denotes a front reinforcing frame in which the tip of the extension portion 26 is fixed by screwing, and is made of L-shaped steel.

Reference numerals 31 and 32 are slip prevention pins provided on the upper surfaces of the front mounting portion 24 and the rear mounting portion 25, respectively, to prevent lateral displacement of the main body 3 from the fixed portion due to vibration during helicopter transportation.

Reference numerals 33 are fixing hooks provided at eight positions on the two vertical frames 21, and the transport pedestal 20 is fixed to the loading platform of the transport vehicle by a wire (not shown). By fixing the helicopter to the transport pedestal 20 via the front mounting portion 24 and the rear mounting portion 25 and fixing the transport pedestal 20 to the loading platform of the transport vehicle via the fixing hook 33, the helicopter becomes the loading platform of the transport vehicle. It is fixed.

Reference numeral 35 denotes a central reinforcing frame whose both ends are screwed and fixed near the center of the two vertical frames 21, which are made of L-shaped steel to reinforce the central portion of the vertical frame 21.

The front mounting portion 24 and both ends thereof are fixed to the front lateral frame 22 via the front legs 28 to form a component unit.

8A and 8B are explanatory views of parts of the rear horizontal frame 23 and the rear mounting portion 25, where FIG. 8A is a front view and FIG. 8B is a side view. The rear mounting portion 25 and both ends thereof are fixed to the rear lateral frame 23 via the rear legs 30 to form a component unit.

9A and 9B are explanatory views of two component units of the front reinforcing frame 27 and the central reinforcing frame 35, where FIG. 9A is a front view and FIG. 9B is a side view. 10A and 10B are explanatory views of one component unit of the vertical frame, FIG. 10A is a front view, and FIG. 10B is a side view.

The parts unit of the transportation frame 20 shown in FIGS. 7 to 10 is set so as to have a safe weight (for example, 35 kg or less) by human power and a unit that is easy to assemble, and can be used in a helicopter storage warehouse or the like. Carrying in and assembling the transportation gantry 20 can be performed easily and promptly.

Next, with reference to FIGS. 11 and 12, the structure of the fixed portion on the back surface of the main body 3 of the helicopter and the method of attaching the transport stand 20 will be described. Reference numeral 13 denotes a back surface of the main body 3 of the helicopter, which is provided with a front fixing portion 10 and a rear fixing portion 11 formed by a U-shaped groove to which the landing gear 7 is attached.

After the landing gear 7 is removed, the front mounting portion 24 and the rear mounting portion 25 of the transport stand 20 are fixed to the front fixing portion 10 and the rear fixing portion 11, respectively.

The front mounting portion 24 and the rear mounting portion 25 are made of a round pipe steel material, and are set to fit into the U-shaped groove of the front fixing portion 10 and the rear fixing portion 11, respectively. Therefore, the lower surfaces of the front mounting portion 24 and the rear mounting portion 25 are flush with the back surface 13 of the main body 3 in the state of being inserted into the U-shaped groove.

In this state, the mounting bracket 12 (shown by the broken line in FIG. 12) is fixed to the back surface 13 of the main body 3. The front mounting portion 24 is fixed in a state of being sandwiched between the front fixing portion 10 and the mounting bracket 12. Similarly, the rear mounting portion 25 is also fixed to the rear fixing portion 11.

Next, the work procedure of removing the landing gear 7 from the fixed portion on the back surface of the main body 3 of the helicopter and fixing the transport stand 20 to the fixed portion will be described with reference to FIGS. 13 to 15.

First, as shown in FIG. 13, the landing gear 7 is removed with the main shaft of the helicopter provided with the main body 3 and the tail boom 6 hung horizontally on a crane (not shown).

Next, as shown in FIG. 14, the helicopter was hung toward the front mounting portion 24 and the rear mounting portion 25 of the transport stand 20 arranged on the ground 103, and the front fixing portion 10 and the rear fixing portion of the main body 3 were hung, respectively. Fit into 11. Then, the transport stand 20 is fixed to the back surface of the main body 3 by the mounting bracket 12 (FIG. 15).

Since the helicopter is in a horizontal posture in FIGS. 13 and 14, the landing gear 7 is removed and the transport stand 20 is attached in a stable state even if it shakes slightly.

Since the front mounting portion 24 is higher than the rear mounting portion 25, the helicopter in the state where the transport pedestal 20 is mounted is in a posture slightly tilted backward from the horizontal in FIG.

The helicopter is loaded into the transport vehicle by the procedure shown in FIGS. 15 to 18. First, from the state of FIG. 15, the main shaft is horizontally lifted by a crane (not shown) and moved above the loading platform 101 of the transport vehicle 100 as shown in FIG. The transport vehicle 100 is, for example, a trailer.

The helicopter moves in a horizontally maintained state, is hung so that the lower surface of the transportation frame 20 is in contact with the loading platform 101, and is installed in a backward tilted posture as shown in FIG. Since the helicopter is suspended from the loading platform 101 in a horizontal position, it is installed on the loading platform 101 in a stable state even if it is shaken slightly by wind or the like.

By the way, in order to transport on public roads using a trailer, it is necessary to obtain a permit for special vehicles in advance. Here, in the state of being mounted on the loading platform 101 shown in FIG. 17 (shown by a solid line), the tail boom 6 protrudes greatly rearward from the loading platform 101 as in FIG. 23. In this case, since the tail boom 6 protrudes beyond the specified loading dimension, it may take a lot of time to obtain the passage permit, and as a result, a factor of increasing the transportation cost occurs.

In this embodiment, as shown by the broken line in FIG. 17, the tail boom 6 is separated from the main body 3, and only the main body 3 is mounted on the loading platform 101 (FIG. 18). The separated tail boom 6 is transported by another truck (not shown). By dividing the tail boom 6 in this way so that the load (the main body 3 of the helicopter) does not protrude from the specified dimensions of the loading platform 101, it is possible to set more advantageous conditions for obtaining the above-mentioned passage permit. At the same time, it is possible to reduce the risk during transportation on public roads and transport safely.

The tail boom 6 is fixed to the loading platform by supporting the support shaft of the horizontal stabilizer 5 by a support (not shown) so as not to protrude rearward from the loading platform of another truck.

When the helicopter arrives at the destination (airfield or the like) in the state shown in FIG. 18, the main body 3 is lifted from the loading platform 101 by a crane and lowered to the ground.

Since the tail boom 6 is separated from the main body 3 on the loading platform 101 of the transport vehicle 100, when it is lifted by the main shaft, it is in a forward leaning posture as shown in FIG. This is because the center of gravity of the main body 3 has moved forward due to the separation of the tail boom 6.

When the main body 3 is about to leave the loading platform 101, the tip of the main body 3 tilted forward approaches the loading platform 101. In this embodiment, just before leaving the loading platform 101, as shown in FIG. 19, the tip 36 of the vertical frame 21 of the transportation platform 20 contacts the loading platform 101 to the end, and the tip of the main body 3 contacts the loading platform 101. I'm avoiding.

The main body 3 lifted by the crane moves to a predetermined place and is hung. When lowered to the ground 103, the main body 3 is suspended in a forward leaning posture as shown in FIG. 20, but the tip 36 of the vertical frame 21 of the transport stand 20 first contacts the ground 103 and is further suspended. Then, the entire vertical frame 21 comes into contact with the ground 103.

In this way, in the lifting of the main body 3 in the forward leaning posture from the loading platform (FIG. 19) and the suspension to the ground (FIG. 20), the tip 36 of the vertical frame 21 of the transport platform 20 is the loading platform 101 or the ground 103. The lower end of the main body 3 does not come into direct contact with the loading platform 101 or the ground 103.

Therefore, since the main body 3, which occupies most of the total weight of the helicopter, does not come into direct contact with the loading platform 101 or the ground 103, damage to the main body 3 due to the weight can be prevented, and the helicopter can be safely loaded and unloaded. be able to.

After being installed on the ground 103, the tail boom 6 is attached to the main body 3. Then, with the main shaft 2 lifted again by the crane and the helicopter maintained in the horizontal posture, the transport pedestal 20 is removed from the front fixing portion 10 and the rear fixing portion 11, and the landing gear 7 is attached instead.

Next, setting the dimensions of the transport stand 20 so that the lower end of the main body 3 does not come into direct contact with the loading platform 101 or the ground 103 will be described.

As shown in FIG. 21, the lower end position of the main body 3 in the suspended state is H1, the position of the tip 36 of the extension portion 26 of the transport frame 20 is H2, and the difference between the positions H1 and H2 is D. In order to prevent the lower end of the main body 3 from directly contacting the loading platform or the ground in the suspended state, the position H2 must be located below the position H1.

In this embodiment, when the main body 3 in the state where the tail boom 6 is separated is lifted from the main shaft 2, the position H2 of the tip 36 of the extension portion 26 of the transport stand 20 is the lowermost end of the main body. The length L of the extension portion 26 is set so as to be located below the position H1 of.

If the height dimension L1 or L of the front fixing portion 10 of the transport frame 20 is set large, the difference D between the positions H1 and H2 becomes large, so that the main body 3 is less likely to come into contact with the loading platform or the ground and is safer. It becomes.

However, if L1 is set large, the height dimension of the transport stand 20 becomes large, so that the mounting height of the helicopter on the loading platform becomes high, which is not preferable.

Therefore, by adjusting the dimension of the length L of the extension portion 26 without increasing L1, the helicopter mounting height can be set to a safe size so that the main body 3 does not come into direct contact with the loading platform or the ground. It is possible to prevent damage to the main body 3 while keeping the size low.

The set value of the length L of the extension portion 26 is, for example, the extension portion 26 of the transport stand 20 when the main body 3 is lifted by the main shaft 2 and when the main body 3 is swayed around the tip of a crane (not shown). The crane locus of the main body 3 is set to be located inward by the distance D from the crane locus of.

Since the mounting parts of the helicopter are determined based on the specifications according to the purpose, the weight distribution of the main body 3 is different. Therefore, the transport pedestal 20 needs to be dimensionally set according to the actual helicopter to prevent damage to the main body.
