Preferred embodiments of the control panel replacement method according to the present invention will be described in detail below with reference to the accompanying drawings.

(Control panel configuration)
First, the configuration of the control panel to be replaced by the control panel replacement method according to the embodiment of the present invention will be described. In this embodiment, the existing control panel to be replaced with a new control panel and the existing control panel to be replaced have the same configuration as the new control panel.

1A to 1C are explanatory diagrams showing an example of a control panel. 1A to 1C, the control panel 100 has a housing 101. As shown in FIG. The housing 101 has a cuboid (rectangular parallelepiped) shape composed of six square faces. In the housing 101, the outer shapes of the surfaces facing each other have the same shape. Specifically, the outer shape of the front and rear portions, the side portions, and the top and bottom portions are the same.

The control panel 100 is installed on the channel base 102 by bringing the bottom surface 101 a of the housing 101 into contact with the top surface 102 a of the channel base 102 installed on the floor surface 130 . As shown in FIG. 1B, the control panel 100 (housing 101 of the control panel 100) and the channel base 102 are separable separate bodies.

A door (not shown) is provided on the front face of the housing 101 when the control panel 100 is installed on the channel base 102 . The door has a substantially plate shape, and is provided so as to open the inside of the housing 101 to the outside using, for example, hinges (not shown).

A control device 103 is provided in the housing 101 . The control device 103 can be implemented by, for example, an electromagnetic switch, a protective device, a circuit breaker for wiring, or a circuit breaker such as an earth leakage circuit breaker. Also, the control device 103 can be realized by, for example, a PLC (Programmable Logic Controller) that monitors and controls the operations of electromagnetic switches, protective devices, circuit breakers, and the like. When working on the control panel 100, the control device 103 inside the housing 101 is opened to the outside by opening the door.

The bottom portion 101a of the housing 101 is provided with an opening 101b penetrating through the bottom portion 101a in the plate thickness direction. A cable processing room (not shown) is provided below the floor surface 130 on which the control panel 100 and the channel base 102 are installed. A cable 104 routed through an opening 130a passing through the surface 130 is connected.

The channel base 102 arranged on the lower side of the housing 101 is a rectangular frame shape having a first opening 102b that opens the top surface 102a and a second opening (not shown) that opens the bottom surface. form. The first opening 102b and the second opening are continuous. The width and depth dimensions of the channel base 102 are substantially the same as the width and depth dimensions of the housing 101 of the control panel 100 .

The depth dimension of the channel base 102 may be longer than the depth dimension of the housing 101 of the control panel 100 . Specifically, for example, when the previous control panel 100 is replaced, the depth dimension of the housing 101 of the control panel 100 before replacement is larger than that of the control panel 100 after replacement. When the control panel 100 after replacement is installed by using the channel base 102 that matches the size of the housing 101 as it is, the depth dimension of the channel base 102 is larger than the depth dimension of the housing 101 of the control panel 100. A long situation arises.

By installing the housing 101 on the channel base 102 , the control panel 100 is installed in a state of being raised from the floor surface 130 by the height of the channel base 102 . By providing the channel base 102 between the bottom surface 101a of the housing 101 and the floor surface 130, the cable 104 routed from the cable processing room is forcibly aligned with the position of the control device 103 in the housing 101. It can be connected to the control device 103 without being bent.

(An example of replacement work for the control panel 100)
Next, an example of replacement work of the control panel 100 for replacing the existing control panel 100 with a new control panel 100 will be described. 2 to 11 are explanatory diagrams showing an example of the replacement work of the control panel 100. FIG. As shown in FIG. 2, the existing control panel 100A to be replaced is arranged next to another control panel 100' side by side with the other control panel 100'.

When replacing the control panel 100 by the replacement method according to the present invention, first, as shown in FIG. 3, a new control panel 100B is temporarily installed near the existing control panel 100A to be replaced. The new control panel 100B is installed on a temporary member 301 having a temporary installation surface positioned at the same height as the top surface 102a of the channel base 102. FIG.

Specifically, the temporary member 301 can be realized by, for example, a rolled steel material formed by rolling ordinary steel. More specifically, the temporary member 301 is, for example, a bar steel material such as H-shaped steel, I-shaped steel, channel steel, or the like, which has a large length dimension compared to the size of the cross-sectional area. etc. can be realized.

The temporary member 301 is temporarily installed around the existing control panel 100A and above the temporary member 301 at a position where a space for temporarily installing the new control panel 100B can be secured. Moreover, the temporary member 301 is temporarily installed in a state in which no separate equipment or device is interposed between the new control panel 100B and the existing control panel 100A. The temporary member 301 is preferably temporarily installed so that the new control panel 100B temporarily installed on the temporary member 301 faces the existing control panel 100A on the front side of the existing control panel 100A.

It is preferable to temporarily install the new control panel 100B in substantially the same orientation as the existing control panel 100A. Specifically, the new control panel 100B is temporarily installed so that the orientation of the door in the new control panel 100B is substantially the same as the orientation of the door in the existing control panel 100A. As a result, the new control panel 100B is temporarily installed with the rear surface of the housing 101 facing the front of the existing control panel 100A.

Next, the existing control panel 100A is moved. Specifically, the existing control panel 100A is moved to the rear side of the existing control panel 100A, that is, to the rear of the existing control panel 100A, as indicated by an arrow 500 in FIG. As a result, the existing control panel 100A moves away from the new control panel 100B along the direction in which the existing control panel 100A and the new control panel 100B face each other.

When moving the existing control panel 100A, a movement guide member 400 is installed to guide the movement of the existing control panel 100A, as shown in FIG. 4, so that the position of the existing control panel 100A does not change in the vertical direction. do. The movement guide member 400 has a flat top surface and a bottom surface, and has a substantially bar shape in which the dimension in the length direction perpendicular to the opposing direction of the top surface and the bottom surface is longer than the distance between the top surface and the bottom surface. When moving the existing control panel 100</b>A, the movement guide member 400 is installed on the floor surface 130 with its bottom surface in contact with the floor surface 130 .

Specifically, the movement guide member 400 can be realized by, for example, a rolled steel material formed by rolling ordinary steel. More specifically, the movement guide member 400 is, for example, a bar-shaped steel material having a large length dimension compared to the size of the cross-sectional area, such as H-shaped steel, I-shaped steel, and channel steel. It can be realized by a bar steel or the like.

The height dimension from the bottom surface to the top surface of the movement guide member 400 is substantially the same as the height dimension of the channel base 102 . The height dimension from the floor surface 130 of the movement guide member 400 to the top surface is preferably equal to the height dimension of the channel base 102 . As a result, by sliding the existing control panel 100A along the top surface of the movement guide member 400, the existing control panel 100A can be moved even in an environment where it is difficult to lift the existing control panel 100A high. The existing control panel 100A can be stably moved without greatly changing the position of the control panel 100A in the vertical direction.

The movement guide member 400 can be realized by a plurality of independent members (for example, two). A plurality of movement guide members 400 are installed in a state in which the length direction is aligned in parallel like rails. By using a plurality of movement guide members 400, it is possible to stably move the existing control panel 100A while ensuring a space below the existing control panel 100A.

The existing control panel 100A is not limited to being moved backward. The existing control panel 100A may be moved in a direction other than the direction approaching the new control panel 100B along the opposing direction of the existing control panel 100A and the new control panel 100B. Specifically, when the new control panel 100B is temporarily installed in front of the existing control panel 100A, the existing control panel 100A may be moved laterally. Alternatively, in this case, the existing control panel 100A may be moved obliquely forward or obliquely rearward. The plurality of movement guide members 400 are arranged, for example, at intervals equal to or less than the dimension of the existing control panel 100A in a direction perpendicular to the moving direction of the existing control panel 100A in the horizontal plane (hereinafter referred to as the "moving width direction" as appropriate). They are placed facing each other and in pairs.

Specifically, for example, when the existing control panel 100A is moved to the rear side, the width direction of the existing control panel 100A becomes the moving width direction. In this case, the paired movement guide members 400 are installed so as to face each other at a distance equal to or smaller than the width dimension of the housing 101 of the existing control panel 100A. Specifically, for example, when the existing control panel 100A is moved sideways, the depth direction of the existing control panel 100A (the direction orthogonal to the width direction in the horizontal plane) is the moving direction. In this case, the paired movement guide members 400 are installed so as to face each other at a distance equal to or smaller than the depth dimension of the housing 101 of the existing control panel 100A.

Alternatively, specifically, for example, when the existing control panel 100A is moved in the diagonal direction of the housing 101, the diagonal direction of the housing 101 is the moving direction. In this case, the paired movement guide members 400 are installed so as to face each other with an interval equal to or smaller than the diagonal dimension of the housing 101 of the existing control panel 100A.

When the movement width direction is a direction inclined with respect to the surface direction of the side surface (or the front surface or the back surface) of the housing 101, such as the diagonal direction of the housing 101, the paired movement guide members 400 face each other. The interval between them differs depending on the moving direction of the existing control panel 100A. When the housing 101 of the existing control panel 100A has a rectangular shape whose depth dimension is smaller than its width dimension, the distance between the pair of movement guide members 400 facing each other along the movement width direction is equal to that of the housing of the existing control panel 100A. It can be the largest when moving in a direction orthogonal to the diagonal direction of body 101 .

By realizing the movement guide members 400 by separate and independent members, the movement guide members 400 forming a pair according to the size and movement direction of the existing control panel 100A, the surrounding conditions of the existing control panel 100A, etc. can be adjusted arbitrarily. Accordingly, the existing control panel 100A can always be supported in a stable state.

In this way, unlike the conventional method, by enabling the existing control panel 100A to move in any direction, it is possible to secure the degree of freedom for the replacement work of the control panel 100. FIG. As a result, it is possible to improve workability and work efficiency compared to the case where work must be done in a narrow space due to the restriction of the movement direction of the existing control panel 100A. can.

The existing control panel 100A is moved until the first opening 102b of the channel base 102 on which the existing control panel 100A is placed is opened to the extent that the cable 104 can pass through. Further, the existing control panel 100A is moved to such an extent that the existing cable 104 is not caught between the inner edge of the opening of the bottom portion 101a of the housing 101 and the channel base . As a result, a cable laying route 600 for passing a cable 700 connected to the new control panel 100B can be secured, as indicated by diagonal lines in FIG.

Then, as shown in FIG. 7, a cable 700 to be connected to the new control panel 100B is routed from the cable processing room via the secured cable laying route 600 and connected. After that, as shown in FIG. 8, the cable 104 connected to the existing control panel 100A is removed from the existing control panel 100A and removed. As a result, only the cable 700 routed from the cable processing room is connected to the new control panel 100B.

Next, as shown in FIG. 9, the existing control panel 100A is removed. Then, the new control panel 100B is moved in the direction indicated by the arrow 1000 in FIG. Specifically, as shown in FIGS. 10 and 11, the new control panel 100B is moved to the position where the existing control panel 100A was installed. When moving the new control panel 100B, a movement guide member similar to the movement guide member 400 ( (illustration is omitted) is installed.

At this time, a movement guide member 400 used for moving the existing control panel 100A is installed between the position where the new control panel 100B was temporarily installed and the position where the existing control panel 100A was installed. You may As a result, the number of members used for the replacement work of the control panel 100 can be reduced. The movement guide member 400 may be removed prior to movement of the new control panel 100B.

As a result, it is possible to prevent the position of the new control panel 100B from fluctuating greatly in the vertical direction. Thus, the new control panel 100B can be reliably moved even in an environment where sufficient space cannot be secured above the installation position of the new control panel 100B.

The new control panel 100B moves while pulling the cable 700 connected to the new control panel 100B from the cable processing room side. This can prevent the cable 700 connected to the new control panel 100B from being excessively bent in the channel base 102. FIG. Thus, the control signal output to the new control panel 100B via the cable 700 can be reliably transmitted to the new control panel 100B.

(Another Configuration of Movement Guide Member)
Next, another configuration of the movement guide member will be described. In the above-described embodiment, an example has been described in which the paired movement guide members 400 are realized by separate and independent members, but the present invention is not limited to this.

FIG. 12 is an explanatory diagram showing another configuration of the movement guide member. As shown in FIG. 12, the paired movement guide members 400 are connected by a connecting member 1200 at one end side in the length direction. The connecting member 1200 that connects the paired movement guide members 400 can be made of the same steel material as the movement guide member 400 . When the paired movement guide members 400 are connected at one end side in the length direction, the paired movement guide members 400 and the connecting member 1200 form a substantially U-shape.

The paired movement guide members 400 may be connected by connecting members 1200 at both ends in the length direction. When the paired movement guide members 400 are connected at both ends in the length direction, the paired movement guide members 400 and the connecting member 1200 form a substantially square shape.

By connecting and integrating the pair of movement guide members 400 by the connection member 1200 in this way, the distance between the pair of movement guide members 400 can be always maintained constant. As a result, it is possible to reduce the burden on the operator involved in installing the paired movement guide members 400 . In addition, it is possible to reduce the burden on the operator involved in transporting the paired movement guide members 400 .

In the above-described embodiment, the method of replacing the control panel 100 that accommodates the control device 103 realized by the electromagnetic switch, protective device, circuit breaker, PLC, etc. in the housing 101 has been described. The control panel 100 to be replaced is not limited to such a control panel 100 . The method of replacing the control panel 100 according to the present invention includes, for example, various types of switchboards that receive high-voltage electricity, convert it to a voltage corresponding to the electrical equipment connected to the secondary side, and then distribute it to a distribution board. It can be applied to the replacement of the board of

As described above, the replacement method of the control panel 100 of this embodiment is to place a predetermined gap between the installation surface of the channel base 102 and the existing control panel 100A installed on the channel base 102 near the existing control panel 100A. A new control panel 100B is temporarily installed while securing a space, and a height equivalent to the top surface of the channel base 102 is placed at an arbitrary position except between the channel base 102 and the temporarily installed new control panel 100B. A moving guide member 400 with a guide surface positioned at .

Then, the existing control panel 100A is moved along the guide surface to a position where a part of the first opening 102b is open to the outside, and the cable 104 is routed through the second opening into the channel base 102. is connected to the new control panel 100B through the first opening 102b opened to the outside, and then the cable 104 connected to the existing control panel 100A is removed from the existing control panel 100A. Later, the existing control panel 100A is removed. After that, a new control panel 100B is moved to a position that closes the first opening 102b.

According to the method for replacing the control panel 100 of the embodiment according to the present invention, by using the movement guide member 400 having the guide surface positioned at the same height as the top surface of the channel base 102, the control panel 100 can be replaced. The existing control panel 100A, which does not have a dedicated mechanism for replacement, can be moved without significantly changing its position in the vertical direction. As a result, the existing control panel 100A can be moved regardless of the installation environment of the existing control panel 100A, such as when a sufficient work space cannot be secured above the existing control panel 100A.

Further, according to the method for replacing the control panel 100 of the embodiment according to the present invention, the movement guide member 400 is installed at an arbitrary position except between the channel base 102 and the temporarily installed new control panel 100B, Since it is sufficient to move the existing control panel 100A to a position where a part of the first opening 102b is open to the outside, even if there is not enough space around the existing control panel 100A, the existing control panel 100A can be A new control panel 100B and the cable 104 can be connected before disconnecting the cable 104 from the control panel 100B. As a result, it is possible to prevent the control panel 100 from being unavailable for a long period of time.

In addition, according to the method for replacing the control panel 100 of the embodiment according to the present invention, by making the movement guide member 400 a separate member from the channel base 102, it is possible to change the position of the existing control panel 100A according to the circumstances around the existing control panel 100A. , the movement guide member 400 can be installed at any position. As a result, a high degree of freedom can be secured in the replacement work of the control panel 100, and workability can be improved.

Further, as a result, the existing control panel 100A does not have to be limited to a specific location such as "only the rear of the existing control panel 100A" or "only the front of the existing control panel 100A". Since the replacement work of the control panel 100 can be performed, a high degree of freedom can be secured in the replacement work of the control panel 100, and workability can be improved.

Further, according to the method for replacing the control panel 100 of the embodiment according to the present invention, the movement guide member 400 is provided separately from the channel base 102, so that it can be installed only when the existing control panel 100A is moved. Just do it. As a result, the new control panel 100B can be installed using the existing channel base 102 that does not have an extra opening for temporarily moving the existing control panel 100A.

Thus, according to the replacement method of the control panel 100 of the embodiment according to the present invention, when the existing control panel 100A does not have a dedicated mechanism for replacement, or when the existing control panel 100A is above the existing control panel 100A The replacement work of the control panel 100 can be performed smoothly and efficiently without being restricted by the work environment, such as when a sufficient work space cannot be secured.

Further, in the method for exchanging the control panel 100 according to the embodiment of the present invention, the movement guide member 400 has a flat top surface and a flat bottom surface, and has a length direction perpendicular to the facing direction of the top surface and the bottom surface. A plurality of independent members each having a substantially rod shape whose dimensions are longer than the distance between the top surface and the bottom surface, and are installed in a state in which the length direction is aligned in parallel, and the existing control panel 100A is It is characterized in that the movement guide member 400 is moved along the length direction to a position where a part of the first opening 102b is open to the outside.

According to the replacement method of the control panel 100 of the embodiment according to the present invention, the interval between the paired movement guide members 400 can be arbitrarily adjusted according to the size and movement direction of the existing control panel 100A. As a result, the existing control panel 100A can always be supported in a stable state, such as at both ends in the movement width direction.

Further, the method for replacing the control panel 100 of the embodiment according to the present invention has a flat top surface and a flat bottom surface, and the dimension in the length direction perpendicular to the facing direction of the top surface and the bottom surface is equal to that of the top surface. A plurality of substantially rod-shaped members longer than the distance from the bottom surface are aligned in parallel in the length direction, and at least one end side in the length direction is connected by a connection member 1200 to move the movement guide member 400. The movement guide member 400 is installed along the movement direction of the existing control panel 100A in the length direction, and the existing control panel 100A is arranged along the length direction of the movement guide member 400 into the first opening. 102b is moved to a position open to the outside.
