Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a departure and arrival support device for a flight-type work machine, and more particularly to a flight-type work machine adapted to perform operations such as spraying a medicine while flying in a relatively low altitude by radio control. It relates to a preferred landing support device.

[0002]

2. Description of the Related Art Conventionally, a flight-type work machine called a radio-controlled helicopter for spraying a medicine, which is used to perform a work such as spraying a medicine while flying in a relatively low altitude by radio control, is a general operating machine operated by a passenger. Helicopters have the same basic configuration, and are often miniaturized versions of helicopters with smaller parts, in other words, helicopters on which people ride.

[0003] Generally, a rotor (main rotor) is disposed on an upper part of a horizontally long fuselage in which a prime mover is arranged, and a torque of the main rotor is offset at a rear part of the fuselage to provide a directional control moment ( A balance rotor (tail rotor) for producing a yawing moment is disposed, and the main rotor (blade) is "softly" jointly connected to its rotation axis (rotor hub) like an articulated joint.・ The degree of freedom of movement of lag and feather was given.

[0004]

The conventional flight-type work machine as described above has excellent motion performance because it is a miniature of a general helicopter operated by an occupant. The structure of the rotor and its drive mechanism, etc., is complicated and expensive, and
Since it is necessary to change the pitch of the rotor, there is a problem that the steering is difficult.

In addition, since the main rotor is usually a single rotor, it is necessary to employ a large diameter rotor in order to obtain a required thrust. As a result, it is necessary to provide a protective cover surrounding the rotor. It is difficult, and it is easy to get caught in electric wires during flight, and safety measures are inadequate.In addition, during transportation, storage, inspection and maintenance, it is necessary to remove the rotor, which requires a lot of trouble. And took time.

Further, while the main rotor is rotating, it is required that no person approach the body, and it is required to stop the rotation of the rotor even at the time of inspection and maintenance or at the time of replenishment of chemicals or fuel. Etc. could not be performed quickly, and there was a problem that operation efficiency was poor. At the same time as the present application, the applicant of the present invention has proposed, as a flight-type working machine, "a vertical side portion and a horizontal side portion connected so as to exhibit a substantially T-shape in a front view or a side view." A vehicle body comprising a side portion and a prime mover arranged on the vertical side portion, and a pair of rotor blades arranged in parallel on the horizontal side portion in a substantially horizontal plane by the power of the prime mover. '' ing.

[0007] In the flight type working machine having such a configuration, since the rotor (main rotor) is twin, the diameter of each rotor can be made smaller than that of the conventional one, and the rotor is used as its rotary shaft. This allows for "rigid" coupling, which can effectively eliminate most of the problems described above. However, the flight type work machine having the above-described configuration has a structural defect that the body is generally T-shaped, so that it is more likely to fall down in the landing state than the conventional one, and Conveniences such as storage, inspection and maintenance, departure and arrival, work preparation, and the like were not sufficiently achieved, and there was a possibility that operation efficiency could not be improved.

The present invention is based on the idea that the above-mentioned problem can be effectively solved by providing a separate landing support device for the above-mentioned flight-type working machine. It can stably support the flight type work machine which is roughly T-shaped so that it can be transported, stored, inspected, maintained, departed and arrived, and prepared for work. An object of the present invention is to provide a flight support / departure support device for a flight-type working machine that can effectively improve the operation efficiency.

[0009]

In a preferred aspect of the present invention, the first support portion and the second support portion are connected to each other, and are generally concave-shaped or laterally inverted in a front view or a side view. More preferably, it is assembled into a skeleton structure with a tube or a rod. Further, in another preferred aspect, the body receiving portion provided on the first support portion is mounted on a cabin of the vehicle, and the body receiving portion provided on the second support portion is mounted on a bed of the vehicle. Are arranged above the equipment storage section.

Further, it is preferable that the first support portion and the second support portion which are connected as described above can be expanded and contracted in the length direction, the height direction, or the width direction as a whole. In the landing support device for a flight-type working machine according to the present invention having such a configuration, the flight-type working machine having a substantially T-shaped airframe is supported substantially horizontally while being floated from the ground. Because of this, it is possible to stably support the flying work machine having a roughly T-shaped airframe without falling down, and
The flying work machine can be taken off directly from the landing support device without touching the flying work machine, and can be directly landed.

[0012] Further, the starting and stopping support device of the present invention can be mounted on a carrier of a vehicle (light truck or the like). In this case, for example, the body receiving portion provided on the first support portion is placed on the cabin of the vehicle, and the body receiving portion provided on the second support portion is placed on the bed of the vehicle. Above the equipment storage section. In this way,
By allowing the landing support device mounted on the vehicle to land and support the flight-type working machine, transportation and the like of the flight-type working machine can be performed easily and safely, and the landing and work preparation can be easily and quickly performed. The operating efficiency of the working machine can be significantly improved.

The limit switch 75 is urged by a built-in spring so that the switching lever 75a is always inclined downward (solid line in FIG. 6). When the switching lever 75a is in the downward state, for example, it is turned ON. When the switching lever 75a is pushed up from the ON state by the operating member 70 and is turned obliquely upward (in a virtual line state in FIG. 6), the switching lever 75a is switched to the OFF state. When it is turned downward, it can be switched to the ON state.

In the flight-type working machine 10 of the present embodiment having such a configuration, during flight (during work), the swing lever 67 of the altitude detector 60 attached to the lower end of the body 12 is used. The hung rope 62 for altitude detection flies in the anti-flight direction and its tip slides on the ground S. In this case, the angle between the altitude detecting cords 62 and the ground and the weight of the altitude detecting cords 62 applied to the body 12 (the swing lever 67) are determined by the flight altitude of the flying work machine 10. smaller extent which is low, becomes highly H ₁ below, wherein the operating member 70 are pushed up by the swing lever 67 becomes less solid line position in FIG. 6, switching the limit switch 75 from OFF to oN Can be From this state, the engine 20

The limit switch 75 is switched from the OFF state to the ON state.

[0037] Thus, in the flight-type working machine 10, the Advanced detector 60, altitude H ₁ and the limit switch 75 to the limit switch 75 is switched from the OFF state to the ON state to the ON state from the OFF state The altitude H ₂ to be switched is detected, and the altitude H ₁ ,
A signal representing H ₂ , that is, the limit switch 7
5 is supplied to a controller 100 (FIG. 3 and FIG. 7) provided in the cylindrical frame 14 of the body 12, and an altitude detected by the controller 100. based on the information, so that the flight altitude is within a predetermined range (range from H ₁ H _2), the engine 20 by an appropriate servo mechanism
Is automatically controlled (described later).

The flight-type working machine 10 having the above-described configuration is used.
Is controlled wirelessly from a transmitter 5 (FIG. 4) placed in a cabin 2 of a light truck 1 on which a landing support device 90 according to an embodiment of the present invention as described later is mounted. I have. That is, as shown in the control system in FIG. 7, the signal emitted from the transmitter 5 is transmitted to the receiver 9 provided in the cylindrical frame 14 of the body 12.
9 (FIG. 3) and transmitted from the receiver 99 to the controller 100 which is also disposed in the cylindrical frame 14. The controller 100 is provided with two CPUs, a machine control CPU 101 for exchanging information with each other and a scatter control CPU 102.

The aircraft control CPU 101 controls flight altitude, flight speed, steering control, attitude control, and the like, and the spray control CPU 102 performs drug spray control. Here, the aircraft control CPU 1
01, the flight altitude is controlled by the altitude detector 6
The operation state of the limit switch 75 from 0 (ON state
By adjusting the opening degree of the throttle valve of the engine 20 based on a signal representing the OFF state, the flight altitude is within a predetermined range (for example, 1.8 to 2.0 m). So that the left rotor 26
This is performed automatically by changing the upward thrust (the strength of the downward airflow) generated by the right rotor 27.

The flight speed is controlled by adjusting the swing angle of the forward / backward moving wings 31, 31 so that the left rotating wing 2
6 and the right rotor 27 are automatically changed by changing the direction of the thrust generated (the direction of the air flow in the front-back direction). The steering control is performed by controlling the lateral movable wing 3.
This is automatically performed by adjusting the swing angles of the rotation blades 2 and 32 and changing the direction of the thrust generated by the left rotor 26 and the right rotor 27 (the direction of air flow in the left and right directions). Thereby, in the flight-type work machine 10 of the present embodiment, it is possible to change the direction from a straight traveling (forward / backward) state or a stopped state to a right angle at a right angle.

The control of the attitude is performed by the movable wing 3 for forward and backward movement.
This is automatically performed by correcting the inclination of the body 12 with respect to the forward and backward directions and the inclination with respect to the vertical line by using all of the movable wings 1 and 31 and the lateral movable wings 32 and 32. In this case, the inclination of the body 12 with respect to the forward / rearward direction is corrected by the centrifugal fan 2 in addition to the movable wings 31 and 32.
An air flow blown from the side 8 through the front blower pipe 41 and the rear blower pipe 42 in the lateral direction is also used.

The medicine spray control is performed by the spray control CPU 102 based on the speed information obtained from the machine control CPU 101 and the spray amount information set by the medicine supply device 39 on the ground. This is automatically performed by controlling the medicine supply device 39 and adjusting the amount of medicine supplied to the spray tube 80.
In this case, when a command to start medicine spraying is received from the transmitter 5 by a wireless signal from the transmitter 5, the spray control CPU 102 activates the medicine supply device 39 to start the medicine spraying operation. , The aircraft control CPU 1
When the altitude information obtained from 01 is out of the specified range, when the altitude information is also 0, when the steering information is also being steered, and when a stop command is received from the transmitter 5 by a radio signal. Then, the medicine supply device 39 is stopped to stop the medicine spraying operation.

The flight-type working machine 10 having the above-described configuration is used.
Since a pair of left rotors 26 and right rotors 27 are provided, the diameter of each rotor 26, 27 can be significantly reduced as compared with a conventional rotor (single rotor machine). The rotor blades 26, 27 can be rigidly and rigidly connected to the rotation shaft 21a.

For this reason, the structure of the rotary wings 26 and 27 can be simplified and inexpensive.
The provision of the movable wings 31 and the lateral movable wings 32, 32 makes it unnecessary to control the pitch of the rotary wings 26, 27, thereby facilitating maneuvering.
It is also possible to provide protective covers 19, 19 surrounding the device 7, so that accidents such as being caught on electric wires during flight are unlikely to occur, and safety is improved.

Further, since the diameter of the rotors 26, 27 is small, the occupied space can be reduced, and the removal of the rotors 26, 27 becomes unnecessary during transportation, storage, inspection and maintenance. Labor and time required for the operation are reduced. Further, the fuselage 12 has a T-shape, and the rotors 26, 2 arranged on the upper part of the fuselage 12 are provided.
Since the protective covers 19 and 19 are provided on 7, a person approaches the body 12 even while the rotary wings 26 and 27 are rotating, thereby increasing safety.

For this reason, it is not necessary to stop the rotation of the rotor even at the time of inspection and maintenance or at the time of replenishment of chemicals or fuel, so that the arrival and departure and preparation of work can be performed quickly, and the operating efficiency is greatly improved. Further, since the altitude detector 60 using the altitude detecting cords 62 can be manufactured at a low cost, the flying altitude can be reliably detected without using an expensive gyro-type altimeter or the like. because it always reliably automatically controlled to fall within a predetermined range (range of H ₁ of H ₂₎ and can be fly stably without causing the accident crash like the relatively low altitude and made with the flight altitude is easy maneuver from being automatically controlled so as to fall within a predetermined range (range of H ₁ of H _2).
