Description

The present invention relates to a control device mount on which a control device such as a control panel, a switchboard, or a relay panel is mounted, and a control device replacement method for replacing the control device mounted on the control device stand.

For example, when replacing (replacement) an existing control panel with a new control panel due to life or failure, the new control panel is due to the small switchboard room or the concentration of various equipment and facilities. It may not be possible to secure a space for installing the switchboard in the switchboard room. In such a case, conventionally, a new control panel has been installed in the arrangement space of the existing control panel. That is, the existing control panel is lifted (raised) from the installation floor to form a space between the existing control panel and the installation floor. Then, through this space, a new cable from under the installation floor was connected to a new control panel, the existing control panel was removed from the arrangement space, and then a new control panel was installed in the arrangement space.

However, since the existing control panel is lifted from the installation floor, all cables connected to the existing control panel can also be lifted. That is, if all the cables need extra length to lift, and the cables do not have extra length, this method cannot be used. Further, since the existing control panel is lifted from the installation floor, a gap is required between the existing control panel and the ceiling, and this method cannot be used when there is no gap for lifting.

For this reason, there is known a control device stand that enables a new control panel to be installed in the arrangement space of the existing control panel without lifting the existing control panel (see, for example, Patent Document 1). This control device mount has a square frame shape, and one side on the front side is a movable side that can move forward and backward with respect to the opposite side. When this movable side is retracted from the opposite side, it controls with this movable side. An extra opening through which a cable can be inserted is formed between the side wall of the panel and the side wall of the panel.
