In addition, the bearing unit 30 is a bearing boss 31 fixed to the rotary shaft 12 and a roller bearing 32 provided outside the bearing boss 31 to rotatably support the rotary shaft 12. ) And a bearing bracket 33 installed on the support frame 11 to support the roller bearing 32.

Of course, in some cases, as shown in FIG. 10, two or more rotary shafts 12 supported by the bearing unit 30 are installed, and each rotary shaft 12 uses different drive unit units 10. By rotating independently of each other, the curtain of the model film 61 may be raised and lowered at different heights for each predetermined area.

The drum unit 40 includes a drum boss 41 fixed to the rotary shaft 12, a bearing 42 rotatably supporting the drum boss 41, and both sides of the bearing 42. A wire drum 43 mounted on the wire rope 43 and wound on the wire rope 14, a drum bracket 44 mounted on the support frame 11 to support the bearing 42, and a drum bracket 44 mounted on the drum bracket 44.

At this time, the drum boss 41 is provided with a limit bolt 47 in contact with the wire drum 43 to limit the relative movement with respect to the bearing 42, the inner gear 41 of the drum boss 41 ') And the external gear 43' of the wire drum 43 is coupled to transmit the rotational force of the rotating shaft 12 to the wire drum 43. Therefore, the drum boss 41 is separated from the inner and outer gears 41 'and 43' of the wire drum 43, so that the wire drum 43 is not rotated, regardless of the rotation of the rotary shaft 12. As shown in FIG. 10, the side curtain 66 may be left as it is, and only the necessary stage facilities 60 such as the flag 67 may be elevated.

As shown in FIG. 9, the rigging apparatus of the present invention is preferably provided with a plurality of rigging apparatuses so as to be movable in the front-rear direction of the grid member 10. Each rigging apparatus includes a banner film 63 and a model film ( 61, the stage hoist 65, the barton 62, and the stage 60 such as the stage 64 are connected to each other to elevate the stage 60. Of course, since the unused rigging device can be moved back and forth due to the trolley wheel 13, it can be collected on one side of the rear side of the stage when not in use.

In addition, the wire rope 14 is preferably installed in a structure in which several small ropes are used, and each turnbuckle 15 is connected to one bracket 16 at each end of the wire rope 14. By doing so, it moves together. Of course, the bracket 16 is connected to the support member coupled to the stage facility 60, such as the pipe band 17 by the fastening member 18, if necessary release the barton 62 and also as a point hoist 65 Can be used in combination.

In addition, the rotary shaft 12 should be formed in a structure that is coupled to or separated from the drive unit 20, the bearing unit 30 and the drum unit 40, when the coupling has a square cross section so as to maximize the contact surface of the fixing bolt. . Of course, it is more preferable to form a hollow hollow in view of the magnetic weight of the rotary shaft 12.

The rigging apparatus of the present invention configured as described above supports various stage facilities and moves up and down the stage facilities while moving in the front-rear direction from the upper side of the stage.

Stage facilities 60 such as banner 63, model 61, point hoist 65, and barton 62 are connected to a rigging device via wire rope, and are elevated on stage according to the operation of each rigging device. .

When the driving motor 21 is operated, since the rotational force of the driving sprocket 24 is transmitted to the driven sprocket 25 by the driving chain 23, the rotating shaft 12 to which the driven sprocket 25 is coupled is rotated. At this time, if the rotation speed of the rotary shaft 12 is too fast, the fall prevention means 50 is activated to block the rotation of the rotary shaft 12. That is, if the actual rotation speed of the rotation shaft 12 is too fast or the output shaft rotation speed of the drive motor 21 is too fast compared to the rotation speed of the rotation shaft 12 corresponding to the output shaft rotation speed of the drive motor 21, the locking member The 54 is operated to be inserted between the ratchet blades 53 'of the ratchet gear 53 to block rotation of the rotary shaft 12. Therefore, it is possible to prevent the stage facility 60 from falling due to the breakage of the drive chain 23.

The bearing unit 30 is installed on the rotary shaft 12 at regular intervals, and is moved in the front-rear direction of the stage together with the driving unit 20 due to the lower trolley wheel 13. Of course, the support frame 11 is firmly attached and supports both ends and the center of the rotary shaft 12 so that the rotary shaft 12 does not sag downward.

 As the rotary shaft 12 is rotated, the wire rope 14 connected to the drum unit 40 is wound or unwound by the wire drum 43, and thus the stage facility 60 is elevated. That is, when the wire rope 14 is wound around the wire drum 43, the stage facility 60 rises, and when the wire rope 14 is released from the wire drum 43, the stage facility 60 descends.

In this case, since the drum unit 40 may be installed by moving in the horizontal direction of the support frame 11, the wire drum 43 may not be rotated even when the rotating shaft 12 is rotated. That is, the wire drum 43 rotates together with the rotation shaft 12 only when the outer gear 43 'of the wire drum 43 is engaged with the inner gear 41' of the drum boss 41, otherwise the wire The drum 43 is not rotated. Therefore, the stage facility 60 connected by the wire rope 14 to the non-rotating wire drum 43 is not lifted.

Of course, to disengage the coupling between the drum boss 41 and the rotary shaft 12 for the movement of the drum unit 40, the external gear 43 'and the inner as necessary in the reinstallation process of the drum unit 40 It is determined whether the gear 41 'is engaged. In this case, the limit bolt 47 provided in the drum boss 41 serves as a reference for setting a position at which the drum boss 41 and the rotary shaft 12 are coupled to each other.

In other words, if the stage facility 60 such as the flag 66 at the center of the stage should be elevated and the side curtain 67 on the left and right sides of the stage should not be elevated, the drum unit 40 is moved and reinstalled as shown in FIG. shall. That is, the wire drum 43 on which the wire rope 14 to which the flag 66 is connected is wound together with the rotary shaft 12, and the wire drum 43 to which the wire rope 14 to which the side curtain 67 is connected is wound. ) May be prevented from rotating together with the rotating shaft 12 by moving and reinstalling the drum unit 40.

In addition, the drum unit 40 has a structure in which two wire drums 43 are disposed on both sides of the drum boss 41, and two wire ropes are arranged at regular intervals by one drum unit 40. 14 is elevated. Thus, it is easier to maintain a balance compared to elevating one wire rope 14, and the stage facilities 60 such as barton 62 after two wire ropes 14 are connected to one bracket 16. Since the stage facility 60 is not rotated.

In addition, the non-rotating wire drum 43 bites and locks the locking device 46 between the ratchet blades of the ratchet gear 45 to prevent the stage facility 60 or the lowering of the wire rope 14 by the weight.

In addition, the rigging device is not provided on the stage alone, but a plurality of dogs are installed, as shown in Figure 9, each of the rigging device (63), the model film 61, the point hoist 65, barton (62), the stage facility 60, such as the stage film (64) is connected and lifted, respectively. Of course, each rigging device is operated independently to elevate the stage facility 60, the unused rigging device is collected to the rear side of the stage. At this time, each rigging device can be moved in the front and rear direction of the stage by using the trolley wheels 13 protruding to the bottom of the support frame 11, the interval between the stage facilities 60 through the movement of each rigging device Will be adjusted.

Although the preferred embodiments of the present invention have been described above, the scope of the present invention is not limited to such specific embodiments, and those skilled in the art may appropriately change within the scope of the claims of the present invention. This will be possible.

As described above, according to the rigging device of the present invention, the device to which the stage facility 60 is connected can be moved in the front-rear direction of the stage, thereby facilitating the positioning of the stage facility.
