In more detail, since the drum 300 is installed in a bearing type rotating in the horizontal direction, the hollow of the drum 300 is opened in the vertical direction. In addition, the connection pipe 210 is formed to extend upward with a diameter smaller than the hollow of the drum 300 at the center of the bottom surface of the main body 200. Therefore, when the connection pipe 210 is installed to be inserted into the opening formed in the drum 300 in the vertical direction, the drum 300 is rotatable outside the connection pipe 210.

At this time, the rotation roll 400 may be installed on the outer wall of the connection pipe 210. When the rotary roll 400 is installed, the drum 300 rotates in contact with the rotary roll 400 when rotating, thereby reducing the friction during the rotation.

That is, the rotary roll 400 is disposed between the outer peripheral surface of the connecting pipe 210 of the main body 200 and the inner peripheral surface of the drum 300 to help the drum 300 rotate more efficiently and stably when rotating in the horizontal direction. give. On the other hand, the rotary roll 400 is inserted into the fixing pin 410 may be configured to rotate around the fixing pin 410.

On the other hand, the wire 800 wound on the drum 300 is described as extending downward through the vertical passage 220 of the main body 200 is guided to the upper portion of the drum 300, the present invention necessarily Without being limited, the wire 800 may be configured to extend downward from a predetermined position outside the drum 300.

In addition, the lower portion of the drum 300 may be formed with a moving roll 320 to help the horizontal rotation of the drum (300). The moving roll 320 may be formed about four places at regular intervals at the bottom of the drum (300). The moving roll 320 installed as described above serves to easily rotate the drum 300 without being directly in contact with the bottom surface of the main body 200 when the drum 300 rotates.

In addition, a gear unit 310 may be formed at an outer periphery of the drum 300, and the drum 300 is rotated by a drive motor 600 having a drive gear 610 engaged with the gear unit 310. can do.

At this time, the gear unit 310 formed in the drum 300 is rotated in the horizontal direction, the drive motor 600 is controlled to rotate in a forward or reverse direction by a separate control unit (not shown).

On the other hand, the guide portion guides the plurality of guide rolls 500 for guiding the wire 800 wound on the drum 300 from the side of the drum 300 to the top of the drum 300, and the top of the drum 300. The intermediate wire 710 for guiding the wire 800 downward through the vertical passageway 220 of the main body 200 may be included.

By such a configuration, the wire 800 is wound or unwound on the drum 300 along the plurality of guide rolls 500. The number and installation positions of the guide rolls 500 may be variously modified, and the wires 800 wound on the drum 300 may be guided to the upper portion of the drum 300, that is, the upper portion of the opening of the drum 300. Is enough.

In addition, the main body 200 may include a casing 700 forming an upper surface of the main body 200. The casing 700 is detachably coupled to the upper portion of the main body 200.

In this case, the intermediate roll 600 may be formed in the middle of the bottom surface of the casing 700. The middle of the bottom of the casing 700 is a position corresponding to the center of the main body 200 and the drum 300. Accordingly, the wire 800 can be moved up and down at a position corresponding to the central axis of the drum 300, that is, at the center of the vertical passage 220 by the middle roll 600 formed in the middle of the bottom surface of the casing 700. do.

Lifting reel 100 according to the present invention configured as described above operates as follows.

First, the lifting reel 100 is installed on the high ceiling surface of the building, the lower end of the wire 800 connected to the lifting reel 100 is provided with a lamp.

In this state, the user inputs a falling signal to the lifting reel 100 using a separate remote controller (not shown) or the like to replace or clean the lamp.

When the falling signal is input, the driving motor 600 is driven, and the driving gear 610 is operated by the driving motor 600. In this case, since the driving gear 610 and the gear unit 310 are gear-coupled, the drum 300 integrally formed with the gear unit 310 rotates. In addition, as the drum 300 rotates, the wire 800 wound on the drum 300 is released.

The wire 800 released from the drum 300 is guided along the guide roll 500, and the middle roll 710 guides the wire 800 toward the middle of the drum 300, that is, the middle of the vertical passage 220. (800) The light connected to the end is lowered to the ground.

After replacing the lamp lowered to the ground or after cleaning, the user inputs a rising signal to the lifting reel 100 using a separate remote controller (not shown).

Then, contrary to the above, the driving motor 600 is reversely rotated, and thus the wire 800 is wound up and wound around the drum 300 while being guided to the intermediate roll 710 and the guide roll 500.

Since the bearing-type drum 300 as described above is installed in a horizontal state lying in the main body 200 rather than being installed in a conventional state, the overall size of the lifting reel 100 can be miniaturized.
