BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a stage driving device capable of wire emergency stop.

In general, the technique of using a pulley to move the stage set up and down is to fix the barton pipe, which can hold the set, to several strands of wire (for example, 4-10 strands) The wire is wound or unwound through the pulley through the main drum, respectively.

In recent years, a structure in which a guide pulley 5 and a return pulley 6, which are vertical pulleys, are fixed to a ceiling iron 20 so as to secure a working space above the grid irons 4 is known as shown in FIG. The wire 3 is pulled by the wire 3 to raise the set 1 and the wire 3 is guided through the guide pulley 5 and the return pulley 6 provided on the ceiling iron 20. The return pulleys 6-1, 6-n are wound or unwound on the main drum 7 provided on the upper surface of the grid iron 4 at a predetermined pitch interval. In this case, the main pulleys 7 corresponding to the return pulleys 6-1 to 6-n are pivoted at a moving angle (for example, 5.8 degrees) corresponding to the moving distance of the wire 3, The tangential angle of the tangential direction of the main drum 7 becomes a swing angle of, for example, a moving angle (for example, 5.2 deg.) According to the side position of the pulleys 6-1 to 6-n, It is difficult to take one roll.

3, when the return pulleys 6-1 to 6-n are viewed on the bottom surface, they are installed at a constant spacing distance as shown in FIG. Because. (6a) is an active axle supporting frame for supporting each of the return axles (6b) of the return pulleys (6-1 to 6-n) to be engaged with each other and is screwed to the ceiling iron (20). 6b are fixed to the right and left axle supporting frames 6a and 6c so as to support the respective pulleys 6-1 to 6-n, A side plate 6d fixedly coupled to the support frame 6a and a bearing 6e for causing the corresponding return pulleys 6-1 through 6-n to adhere to the respective drive axles 6b, And a frame support shaft which is provided in the vicinity of the outer periphery of each of the corresponding return sheaves 6-1 to 6-n to support the sheave support frame 6a and prevent the wire rope 3 from coming off.

On the other hand, a stage equipment lifting device of the Utility Model Registration No. 20-0435379 has been developed, which is provided with a base, a winding drum provided on the base and formed with a spiral groove on the outer circumferential surface thereof, A lifting member which is connected to one end of the winding drum and is wound or unwound in the spiral groove of the winding drum in accordance with normal and reverse rotation of the winding drum by the power means to raise and lower the stage equipment; A slide member for moving the winding drum in a winding or unwinding direction of the lifting member so as to be accurately received in the spiral groove, and a release preventing member formed at a lower portion of the winding drum so as not to separate the lifting member accommodated in the helical groove .

Also, in the stage driving apparatus, a method of electrically isolating the pulleys from the main drum using a screw drum type to prevent rapid descent of the wires is disclosed in Korean Patent Registration No. 10-0645892, Korean Patent Registration No. 10-1362410, Although it was developed as registration No. 10-1566656, it has a problem in that it can not be operated normally when a fire or power is cut off.

Another object of the present invention is to provide a method and apparatus for automatically releasing a fast protruding bar on the surface of a roller due to mechanical inertia when a speed loosening occurs due to an abnormal loosening of a wire unwound from a main drum to wind or unwind a wire of a stage driving device, Due to the interlocking rack and pinion, the inclined pushing bar descends like a wedge and slides down the fixed bar, so that the wire is pressed and fixed, preventing the rapid descent of the wire by a mechanical device to prevent safety accidents.

Another object of the present invention is to provide a method and apparatus for automatically releasing a fast protruding bar on the surface of a roller due to mechanical inertia when a speed loosening occurs due to an abnormal loosening of a wire unwound from a main drum to wind or unwind a wire of a stage driving device, Since the interlocking rack and pinion are arranged vertically in a row, the inclined pushing bar is inclined like a wedge, and the wire is fixed by pushing the wire at the same time from the top and bottom, so that the force for holding the wire is dispersed vertically even at high speed, To prevent falling.
