In addition, the main frame 100 may be coupled to the cross member (C) on both sides so as to be transportably mounted on a separate structure to be movable to the transfer rail or the like. At this time, a separate hook ring (C1) is formed in the cross member (C) may be configured such that the main frame 100 is fixed to the transport rail, such as a wire (not shown) through the hook ring (C1).

The rotating shaft 600 is rotatably coupled to the main frame 100, and the rotating frame 200 is coupled to one end of the rotating shaft 600. That is, the rotation shaft 600 is rotatably coupled through the bearing 700 mounted on the main frame 100, and the rotation frame 200 is mounted at one end of the rotation shaft 600 to be rotated with the rotation shaft 600.

The object to be rotated 500 is coupled to the rotation frame 200 such that the central axis 501 crosses the rotation axis 601 of the rotation shaft 600 inclined. That is, as shown in FIG. 4, the rotating shaft 600 and the rotating frame 200 rotate in a state in which the central axis 501 of the rotating body 500 is inclinedly coupled with the rotating shaft 601 of the rotating shaft 600. 2 and 3, the central axis 501 of the to-be-rotated body 500 rotates 360 ° in a precession manner about the rotation axis 601 of the rotation shaft 600. (A) and (b) of FIG. 2 show a state in which the rotating frame 200 and the to-be-rotated body 500 are rotated 180 degrees, respectively.

According to this structure, the function performed by the rotating body 500 is to work evenly over a wide range around the rotating body 500. For example, as shown in FIG. 1, when the rotating body 500 is a blowing unit that blows wind, the wind blown by the rotating body 500 is wide in a direction radiated about the rotating body 500. It will work over. At this time, what can be applied to the object to be rotated 500 may be changed in various ways such as not only a blowing unit, but also a liquid injection device or a heater.

Therefore, in the rotation driving apparatus according to the embodiment of the present invention, when the driving means 300 drives the rotation shaft 600 to rotate, the rotation frame 200 rotates, and thus the object to be rotated 500 rotates.

At this time, the object to be rotated 500 is supplied with power to operate the blower fan 530, the liquid injection device 540 or a heater (not shown), as described above, the object to be rotated ( 500) should be connected to the power supply line. However, since the rotating body 500 is driven to rotate together with the rotating shaft 600 and the rotating frame 200, the wires connected to the rotating body 500 are twisted by the rotation and cannot be used through a general wire connection method. do. Therefore, the rotation drive device according to the present invention is provided with a slip ring assembly 400 and the connection cable (W2) to prevent the twist of the wire connected to the object to be rotated (500).

The slip ring assembly 400 is coupled to the rotary shaft 600 and the rotor portion 410 rotates integrally with the rotary shaft 600, the electrical contact with the rotor portion 410 is fixedly disposed in a rotationally constrained state It is configured to include a stator unit 420, the power is supplied from the outside to the stator unit 420 is configured to continuously supply power to the rotating rotor unit 410. At this time, the stator 420 is supplied with power from the outside through a separate power cable W1.

The connection cable W2 connects the rotating body 500 and the slip ring assembly 400 to supply power to the rotating body 500, and one end of the connecting cable W2 is connected to the rotor portion 410 of the slip ring assembly 400. And the other end is coupled to the rotating body 500, a portion of the intermediate section is configured to pass through the cable hole 620 of the rotating shaft 600. In this case, a separate insertion hole 610 is formed on the circumferential surface of the rotating shaft 600 so as to communicate with the cable hole 620, the connection cable (W2) of the rotating shaft 600 through the insertion hole 610. Configured to pass through the inner cable hole 620. That is, the connection cable W2 is configured such that one end is connected to the rotor unit 410 and the other end is connected to the rotating body 500 through the cable hole 620.

According to this structure, one end of the connection cable W2 is rotated together with the rotor part 410 which is integrally rotated with the rotary shaft 600, and at the same time, when the rotary shaft 600 rotates together with the to-be-rotated body 500. Since the other end is rotated, since relative rotation does not occur at both ends, even if the to-be-rotated body 500 rotates, the twisting phenomenon is prevented. Therefore, the rotation drive device according to the present invention is a structure that can be smoothly rotated with respect to the to-be-rotated body 500 by preventing the twisting of the wire even in a long time use.

On the other hand, the rotating frame 200 according to an embodiment of the present invention, as shown in Figures 1 and 2, the horizontal portion 210 and the horizontal portion 210 is coupled to the rotational shaft 600 in a right angle in the center portion. The first vertical portion 220 and the second vertical portion 230 extending downward in the orthogonal direction, respectively, at both ends. In this case, the first vertical portion 220 extends downward longer than the second vertical portion 230, and thus, the imaginary line connecting the ends of the first vertical portion 220 and the second vertical portion 230 is thin. It becomes photograph form. The object to be rotated 500 is coupled to the lower ends of the first and second vertical parts 220 and 230 configured as described above, and the central axis 501 is disposed to be inclined with respect to the rotation axis 601 of the rotation shaft 600. It may be configured in the form.

In this case, the object to be rotated 500 may be configured in such a manner as to be directly coupled to the lower ends of the first vertical part 220 and the second vertical part 230, as shown in FIGS. 1 and 2. It is preferably configured in such a way that it is suspended in the rotary frame 200 via wires S having flexibility respectively connected to both ends of the). At this time, the wire (S) may be formed of a chain structure in which a metal hook (not shown) is connected continuously or made of a metal wire, etc., having flexibility and supporting the to-be-rotated body 500 by tension. It can be produced in various forms. According to the suspension structure of the object to be rotated 500, vibration between the object to be rotated 500 and the rotating frame 200 may be insulated through the wire S, thereby achieving a more stable structure. In this case, the wire S may be directly connected to both end portions of the rotating frame 200, but as shown in FIG. 1, separate cross members C are coupled to both side ends of the rotating frame 200, and cross each other. It can be configured in such a way that is connected via the hook ring (C1) formed in the member (C), it can achieve more structural stability.

In addition, when fixing the to-be-rotated body 500 to the rotating frame 200 through the wire (S) in this way, the inclination angle of the to-be-rotated body 500 through the length adjustment of the wire (S) as shown in FIG. Can be adjusted. That is, when the length of the wire S is formed as shown in (a) of FIG. 4, the angle between the central axis 501 of the to-be-rotated body 500 and the rotation axis of the rotation shaft 600 is shown in FIG. 4B. When the length of the wire (S) is relatively longer than (a) of FIG. 4, as shown in (b) of FIG. The angle between the central axis 501 and the rotation axis of the rotation shaft 600 forms a relatively large θ2. As such, the application area for the operation function of the to-be-rotated body 500 is changed by adjusting the angle between the central axis 501 of the to-be-rotated body 500 and the rotational axis of the rotary shaft 600. The length of the wire (S) can be used in various adjustments.
