That is, the first winding drum unit 20, the second winding drum unit 30, and the third winding drum unit 40 can be controlled to rotate in series by the driving force provided by the cylindrical motor 203. .

The third guide roller 4053 moves along the third guide axis 4051, and the control signal input/output cables 408 and 409 move in the first area ( It can be guided to be accommodated in the grooves 70 formed on the surfaces of the second area 4013) and the second area 4015, respectively.

More specifically, when the control signal input/output cables 408 and 409 are respectively wound or unwound around the third winding drum 401, the control signal input/output cable extends downward to the third winding drum 401. (408, 409) is caught by the third guide roller 4053, so that the control signal input/output cables 408, 409 are connected to the third winding drum 401 in a direction perpendicular to the axial direction of the third winding drum 401. ) can be wound or unwound.

Therefore, the third guide roller 4053 guides the control signal input/output cables 408, 409 to be wound around the third winding drum 401 without being twisted, and at the same time, the control signal input/output cables 408, 409 are It can prevent it from leaving the outside.

As the third guide shaft 4051 is linked with the rotation direction and rotation speed of the third winding drum 401 by the belt 60, the third guide roller 4053 also moves on the third guide shaft 4051. It may be interlocked to rotate in the same direction and speed as the third winding drum 401.

The second support member 407 connects the third drum protrusion 403 and one side of the third guide shaft 4051, and may support the third guide shaft 4051.

The first winding drum unit 20, the second winding drum unit 30, and the third winding drum unit 40 of the raising and lowering stage device 1 according to an embodiment of the present invention having the above-described structure are cylindrical motors. It can be controlled to rotate in series by the driving force provided by (203).

Therefore, the connecting member 209, power cable 309, and control signal input/output cables 408, 409 can be wound or unwound from each winding drum by one cylindrical motor 203, thereby saving power. There is an effect.

In addition, since the cylindrical motor 203 uses a single-phase motor, it is easier to install and maintain compared to a conventional stage lifting and lowering device that mainly uses a three-phase motor.

The lifting and lowering stage device (1) according to the present invention has a spiral groove (70) formed on the surface of each winding drum (201, 301, 401), and guide roller parts (205, 305, 405) are provided at the lower part. Thus, twisting or overlapping of the connection member 209, power cable 309, and control signal input/output cables 408 and 409 can be effectively prevented in the process of winding or unwinding.

In addition, the first winding drum unit 20, the second winding drum unit 30, and the third winding drum unit 40 are located in an area defined by the first partition wall 11 inside one case 10. They are each arranged in parallel and spaced apart by a predetermined distance, minimizing interference from air conditioning ducts or cable ducts in the upper space of the ceiling, or various exposed cables, and can be installed in narrow spaces.

The lifting and lowering stage device (1) according to the present invention is equipped with an electrical input terminal (13) and control signal input/output terminals (15, 17) in the case, and a power cable (309) and a control signal input/output cable (408). , 409), one side is connected to the baten device, allowing for easy installation and construction without the need for separate wiring work.

Although various embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the claims and equivalents of the claims as well as the claims described later.
