2. Description of the Related Art Since an open / close device such as an electric circuit breaker, a lightning arrester, and a grounding switch has a weight of several tens to several hundreds of kg, it is necessary to pull out the device from a switchboard during maintenance or inspection.
Since it is almost impossible to perform the work of mounting and mounting by human power, a dedicated lifter is used for this purpose.

FIG. 2A is a side view showing a conventional lifter combined with a switchboard, and FIG. 2B is an external view of the lifter. In FIGS. 2 (a) and 2 (b), 1 is a switchboard, 2 is a distribution device, 3 is a drawer carriage, 3a is a disconnection position where the electric circuit is separated by a safe distance, and 4a is a fixed connection to the switchboard. vessel,
4b is a connector attached to the distribution device 2, 5 is a lifter, 5a
Is a lift truck of the lifter 5, 5b is a drawer carriage stopper attached to the lift truck 5a, 5c is a wheel for moving the lifter 5d, 5d is a lifter stopper for fixing the lifter 5 to the floor surface, and 5e is a lifter for moving the lifter 5. In this case, the turning wheels, 5f are lifting devices for the lifting platform 5a, and 5g is a main mast that also serves as a lifting guide for the lifting platform 5a.

The lifter shown in FIG. 2 (b) has a moving wheel 5
c is equipped with a lifting platform 5a that moves up and down by operating a handle on a movable carriage configured to be manually movable by means of c and a turning wheel 5e.
Open the door, move the lifter 5 to the front of the delivery device 2 for withdrawing, and operate the handle attached to the elevating device 5f to move the elevating platform 5a up and down to match the level with the withdrawing cart 3. The lifter stopper 5d is lowered to the floor surface to fix the lifter 5, and an adapter (not shown) with wheels mounted on the elevating platform 5a is mounted on the elevating platform 5.
It is moved forward along the rail on a and fixed to the drawer cart 3, and the adapter (not shown) is retracted to collect the opening and distributing device 2 together with the drawer cart 3 on the elevating platform 5a. After that, the drawer cart stopper 5b is fixed so that the drawer cart 3 does not return, and then the lifter 5 is moved, or the elevating / lowering platform 5a is moved up and down along a guide provided on the main mast 5g for maintenance, inspection, etc. I do.

SUMMARY OF THE INVENTION In the conventional lifter,
Access to the switchboard and positioning are performed by a mobile trolley,
In order to accurately align the adapter mounted on the lifting platform with a predetermined device mounting position, it is necessary to repeatedly move the lifter so that the adapter comes directly in front of the device, which is a troublesome task. Further, there is a problem that a place where the lifter is always stored is required.

An object of the present invention is to provide a drawer device for an opening and closing device, which does not require much labor for positioning when taking out the opening and closing device from a switchboard and has a storage space smaller than that of a conventional lifter.

In the drawer device of the distribution device of the distribution board having the drawer carriage that performs the connection operation to the disconnection device and the movement operation to the disconnection position of the distribution equipment, the distribution device with the drawer carriage has horizontal elongated holes on both sides. A bottom plate for mounting the device is provided, and a frame having an engagement pin that engages with the elongated hole is provided on both side surfaces of the switchboard at substantially the same height as the bottom plate, and is a drawer device of the distribution device.

According to a second aspect of the present invention, in the drawer device of the opening and closing device according to the first aspect, there are provided a hanging device for hoisting and lowering the opening and closing device, and a hanging frame which is attached to an upper portion of the switchboard and hangs the hanging device. The withdrawal device of the provided distribution device.

[0009]

[Operation] A pin having a wheel attached to one end thereof is horizontally attached to the frames on both side surfaces of the switchboard, and the wheel is engaged with the long hole of the bottom plate. Is pulled out of the switchboard together with the bottom plate, or is pulled in from the outside of the switchboard. Further, the bottom plate fixing pin hole provided in the frame fixes the bottom plate by inserting the bottom plate fixing pin into the pin hole.
