The configuration of the main part of the present invention, the horizontal maintenance device is coupled to the boarding box 20 of the vehicle 10 of the high vehicle, and is mounted on the boarding connector 20, the inclination of the boarding 10 A control unit 35 for controlling the driving motor 40 by receiving the sensing means for sensing and the detection signal by the sensing means, a drive motor 40 operated by a control signal by the control unit 35, and the drive One side is coupled to the drive shaft 41 of the motor 40 to reduce the driving force, and the reducer 45 and the drive motor 40 are mounted, and one side is coupled to the end of the boom 15. It is made of a boom connecting portion (50).

Here, the board connection portion 20 is coupled to the other side of the boom bar connecting portion 50 while being engaged with the gear connecting plate 22 and the drive gear 46, the flat cross section is formed in a 'T' shape. It consists of a horizontal adjustment gear 26 to maintain the horizontal of the boarding box (10).

The gear connecting plate 22 is formed of a plate-like connecting plate 23 detachably coupled to the boarding box 10, and a fixed plate 24 coupled to the connecting plate 23 at a right angle, the fixing plate ( The horizontal adjustment gear 26 is bolted to the side of the 24.

The connecting plate 23 may be coupled to the boarding box 10 by fixing with a bolt or the like. As shown in FIG. 6, the connecting plate 23 is provided with a connecting ring 11 at one side of the boarding box 10. (23) can be fitted from the top, and at this time, the connecting ring 11 is provided with a separate fixing bracket (23a) on the connecting plate 23 so that the connection plate 23 does not flow in the bolt coupling It is preferable to be.

The horizontal adjustment gear 26 is formed in an annular shape formed with a plurality of teeth on the outer circumferential surface can be attached to the protrusion jaw 25 formed on the side of the fixing plate 24 to attach, and the side of the fixing plate 24 After the plane is formed, the ring-shaped horizontal adjustment gear 26 may be attached or manufactured in a separate disc shape.

Therefore, in the case of adjusting the level of the boarding box 10, the driving force of the drive motor 40 mounted on the boom 15 is decelerated through the reducer 45 and then transmitted to the drive gear 46. The drive gear 46 is rotated, and the horizontal adjustment gear 26 engaged with the drive gear 46 is rotated to adjust the level of the boarding box 10.

At this time, the sensing means for detecting the horizontal level of the boarding box 10 when the level of the boarding box 10 is coupled to the gear connecting plate 22 of the boarding board connection portion 20 the boarding box 10 'U' shaped horizontal control tube 30 having a plurality of flow balls 31 built therein so as to sense the level of the horizontal control tube 30 is provided between both ends of the horizontal control tube 30 It is composed of a sensor 33 for detecting the horizontal, the horizontal control tube 30 and the sensor 33 is preferably embedded in a separate protective case 38 to be protected from external impact.

That is, when the boarding box 10 is inclined, as the moving ball 31 provided in the horizontal control tube 30 is moved in an inclined direction, the detection sensor 33 is the boarding box 10 By detecting the presence or absence of the horizontal) to transmit the detection signal to the control unit 35 will be able to immediately control the horizontal of the boarding (10).

In this case, the flow ball 31 is a certain weight on the outside of the flow ball 31 located on the outermost side of the plurality of flow balls 31 so that the flow ball 31 does not flow during the external shock or vibration in the interior of the horizontal control pipe (30) The flow prevention port 32 is further provided. That is, it is preferable that the flow prevention port 32 is provided in the horizontal control pipe 30 to prevent unnecessary flow of the outermost flow ball 31.

The boom bar connecting portion 50 of the present invention is configured to connect to the boom 15 in a state in which the drive motor 40 and the reducer 45 is mounted together with the connection to the boarding box connection 20, The boom in the top of the boom 15 may be used as the boom connecting portion 50 of the present invention.

In addition, the reducer 45 is a brake with a built-in brake, and the driving gear 46 to the reducer 45 to prevent the rotation of the gear while the locking gear provided therein when the drive motor 40 is not operated. It is to prevent the rotation of the horizontal adjustment gear 26 connected through the, the internal structure and operation principle of the reducer 45 is obvious because it is a known technology will not be described herein.

On the other hand, as shown in Figure 8, when the boarding box 10 is unused or separated in the combined state, a separate fastening plate 16 is mounted on the end of the boom 15 so as to facilitate the transfer operation of the load, etc. Next, the fastening plate 55 having a predetermined length may be fastened to the fastening plate 16.

In addition, as shown in FIG. 9, the board 10 may be detached from the board 10, and the transport table 55 may be fastened to the connecting plate 23. In this case, the connection as shown in FIG. The plate 23 is provided with a separate fixing bracket (23a) is preferably bolted to the transfer table 55, using the drive motor 40, the reducer 45, the horizontal adjustment gear 26 and the like. By easily adjusting the angle of the transfer table 55 it is possible to carry out the transfer operation of the load more smoothly.

Looking at the operation and effect of the present invention configured as described above, after parking the aerial vehicle at the position to be worked, the boom 15 is extended to increase the boarding 10 to the working position and then the boarding (10) You can do this after adjusting the horizontal level.

At this time, when the horizontal adjustment of the boarding box 10 to detect the horizontal state by the detection means attached to the boarding board connecting portion 20 for connecting the boarding box 10 to adjust the level of the boarding box 10 do.

That is, when the boarding box 10 is inclined to one side, the floating ball 31 embedded in the horizontal control tube 30 is in the inclined direction, in which case the detection sensor 33 is Detects that the floating ball 31 is not in a horizontal state and transmits a detection signal to the controller 35.

When the control unit 35 receives a detection signal, the control unit 35 operates the driving motor 40, and the horizontal connection provided in the boarding connection unit 20 via the reduction gear 45 by the operation of the driving motor 40. The adjusting gear 26 is rotated.

By the rotation of the horizontal adjustment gear 26, the boarding box 10 is gradually closer to the horizontal, the floating ball provided on both sides of the horizontal control pipe 30 when the boarding box 10 is horizontal ( 31 is kept horizontal with each other, the detection sensor 33 detects the horizontal and transmits to the control unit 35, the control unit 35 stops the driving of the drive motor 40 In addition, when the horizontal adjustment gear 26 is engaged with the driving gear 46 connected to the reduction gear 45, the rotation stops and stops.

As described above, the present invention can maintain the level of the boarding box 10 in a smooth operation, and can be detected more accurately, which is a useful invention that enables a worker to achieve stable work.
