Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead door opening / closing drive device, and more particularly to an overhead door opening / closing drive device connected to an overhead door to open / close the overhead door, .
Among various techniques related to the opening / closing drive device of the overhead door,
Korean Registered Patent No. 10-1299647 (registered on Aug. 19, 2013, hereinafter referred to as "prior art") "drive device for overhead shutter" is proposed.
In the prior art,
A hinge includes a shutter composed of a plurality of shutter plates connected by a hinge, a roller is coupled to the hinge, and a guide rail is disposed on which the roller is disposed.
A drive shaft rotated by a drive motor is disposed above the guide rails, and sprockets are axially coupled to both sides of the drive shaft.
In addition, the chain is wound on the sprocket, one end of the chain is fixedly coupled to the lower end of the shutter, and the other end is arranged to extend downward through the sprocket.
In the state of operation of the prior art constructed as described above,
When the drive shaft is rotated by the drive motor, the sprocket axially coupled to the drive shaft rotates and the chain wound on the sprocket is driven.
Then, the one end of the chain is lifted and the shutter fixedly coupled to the one end is raised.
Further, as the roller connected to the shutter by the hinge moves along the guide rail, the shutter is lifted along the outer periphery of the guide rail, and the shutter is opened.
At this time, as one end of the chain rises toward the sprocket, the other end of the chain descends.
When the shutter is closed, as the drive shaft rotates in the direction opposite to the open state, the other end of the chain rises and the one end of the chain is lowered, so that the shutter fixedly coupled to the one end is lowered.
However, when the shutter is opened and closed, the other end of the chain tangles or rocks as the chain ascends and descends.
Therefore, the lifetime of the chain is shortened, and the opening and closing operation of the shutter may not be performed smoothly or may be interrupted.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an overhead door opening / closing drive device which prevents the chain from tangling or fluctuating when the overhead door is opened or closed.
According to an aspect of the present invention, there is provided an apparatus for opening and closing an overhead door,
Two frames spaced apart from each other;
An overhead door provided between the two frames so as to be vertically openable and closable;
A drive shaft disposed on the frame and rotated by a drive motor;
A sprocket coupled to both ends of the drive shaft;
A chain engaged with the sprocket and having one end connected to one side of the lower end of the overhead door and the other end extending downward through the sprocket; And
The weight attached to the other end of the chain
.
A guide fixed to the frame, the guide being disposed along a path where the weight is raised and lowered when the overhead door is opened and closed; And
A slide connected to the guide and the weight, the slide being installed to be able to move up and down with the guide;
.
An overhead door opening / closing drive device according to the present invention comprises:
So that the lifting operation of the chain can be carried out smoothly when the overhead door is opened or closed, so that the life of the chain can be extended and the stopping of the opening and closing operation can be prevented.
