Description

{PULLING-UP APPARATUS}

The present invention relates to a selective lifting device provided between adjacent sliding doors to selectively open or close some of a plurality of sliding doors provided in various structures such as a gymnasium, a warehouse, a hydrological gate, and the like.

In the case of a structure such as a logistics center or a container, the cargo must be sequentially loaded from the lower part to the upper part or from the left to the right in order to load the cargo as efficiently as possible in a certain space.

Such a structure is usually provided with sliding doors or door-type doors on both sides of the opening and closing door in a manner of sliding up and down or right and left sliding.

However, in the conventional door as described above, as the size of the opening / closing port increases, the number of doors increases, so that opening and closing may not be smooth, and a space for opening and closing according to the turning radius of the door is required.

Accordingly, a plurality of door panels are provided in one opening / closing port, and these sliding doors are sequentially folded to sequentially open / close the opening / closing ports (Patent No. 10-1300450, etc.).

However, the above-described sliding door can reduce the weight of each door panel and reduce the door opening space, which is advantageous in terms of space utilization. However, if the door panel is not sequentially moved and folded, It can lead to loss.

Further, since only a part of the door panel can not be opened or closed, when a part of the structure is to be opened or closed, a plurality of doors must be separately manufactured and installed and opened and closed. Therefore, the manufacturing cost is high and the user has to approach the door directly to open and close the door. Therefore, there is a disadvantage that safety is required when opening and closing the door installed on the slope.

Especially, in case of watercraft, it is necessary to selectively open and close only the bottom gate at the maintenance level.

In order to solve the above-mentioned problems, according to the present invention, in a variety of structures such as a gymnasium, a warehouse, a hydrological gate, and the like, sliding doors are provided in a plurality of opening / In order to avoid the need for a lifting device.

The present invention provides a selective lifting device capable of selectively opening and closing a plurality of sliding doors spaced apart from each other, and capable of opening and closing safely without risk of a safety accident even in the case of a door installed on a sidewalk or a slope.

According to a preferred embodiment of the present invention, there is provided a selective lifting device provided between adjacent sliding doors for selectively opening and closing a plurality of sliding doors spaced apart from each other in a row, And a groove is formed along the inner circumferential surface of the through hole so that the groove is equal to or greater than the number of the sliding doors; And a shaft through which the through hole of each of the support members is rotatably and slidably coupled, the shaft having a protruding portion formed at a position below the support member; Wherein one of the groove portions of the retainer is closed so that the retaining portion is engaged with the retaining portion and the retaining portion is formed at a position different from the retaining portion of the other retaining portion.

According to another preferred embodiment of the present invention, there is provided a selective lifting device, wherein a rotating part for rotating the shaft is provided on one side of the shaft.

According to another preferred embodiment of the present invention, there is provided a pick-up device, wherein a shaft for sliding the shaft up and down is provided at the upper end of the shaft.

According to another preferred embodiment of the present invention, the rotary part includes a guide rail part formed at one side of the shaft and protruding or being recessed in the longitudinal direction of the shaft; A rotation ring coupled to an outer circumferential surface of the shaft to rotate the shaft to receive the rotational force of the driving unit and having an engaging key portion engaged with the guide rail portion and transmitting a rotational force to the shaft, And a driving unit for driving the rotary ring; And a selection lifting device for lifting the selected lifting device.

According to another preferred embodiment of the present invention, a fixing groove is formed on the outer surface of the shaft near the rotation part at a position corresponding to the groove of the support in the longitudinal direction of the shaft, And a retaining ring having a fixing protrusion which is elastically pressed to fix the rotation angle of the shaft.

According to another preferred embodiment of the present invention, a rotating part is inserted into an outer portion of a shaft to which the rotating part is coupled, so as to guide the rotational movement of the rotating part, and a first guide groove formed in the circumferential direction of the shaft, And a rotary part position fixture is provided which is provided with a plurality of second guide grooves formed in the longitudinal direction of the shaft at positions corresponding to the respective grooves of the support so as to guide linear movement of the rotary part.

According to another preferred embodiment of the present invention, an optional lifting device is provided on the outer circumferential surface of the shaft on the upper side of the support, wherein the auxiliary lifting device is provided at a position facing the engagement protrusion.

The present invention has the following effects.

First, since a plurality of sliding doors are provided so as to be spaced apart from each other in various structures such as a gymnasium, a warehouse, and a hydrological gate, there is no need to increase the size of the door or increase the weight of the door.

Second, the shaft installed in the through hole of the support is rotated so that the shaft of the shaft is caught or released from the engagement portion provided on the support of the desired sliding door, thereby selectively opening and closing the desired one of the plurality of sliding doors .

Third, even in the case of a sliding door installed on a water gate, a slope or the like, only a part of the sliding doors can be selectively opened and closed. Accordingly, it is not necessary to individually open and close the sliding doors, so that the installation cost associated therewith can be reduced, and the sliding doors installed on the inclined places can be safely opened and closed without risk of safety accidents.
