Description

The present invention relates to a control panel replacement method for replacing an existing control panel with a new control panel.

Conventionally, there have been various techniques for replacing an existing control panel with a new control panel. Specifically, conventionally, for example, a guide rail is installed between an existing control panel (old switchboard) and a new control panel (new switchboard) temporarily installed to face the front of the existing control panel. Then, after connecting the new cable to the new control panel, remove the old cable connected to the existing control panel, remove the existing control panel from which the old cable was removed, and then add the new control panel via the guide rail. There has been a technique for moving the above to the mark position of the existing control panel (for example, refer to Patent Document 1 below).

Also, specifically, conventionally, for example, a new cable from under the installation floor is connected to the control device of the new control panel through the excess opening of the channel base protruding from the existing control panel, and the existing cable is connected to the existing control panel. There has been a technique in which an existing control panel is removed after being removed from the panel, and a new control panel is moved to a position where the existing control panel was installed (for example, refer to Patent Document 2 below).

Further, specifically, for example, conventionally, for example, an opening portion facing a cable pit formed on a floor, a cable laying hole provided in the lowermost front surface, and a cable laying hole are openably closed. There has been a technology relating to a control panel having a casing provided with a closing member and a method for replacing the control panel (for example, refer to Patent Document 3 below).

Further, specifically, conventionally, for example, a vertical movement mechanism that is provided at four corners of the bottom of a control panel (switchboard) to move the control panel up and down while maintaining the horizontal state of the bottom of the control panel; There has been a technology relating to a control panel provided with a drive mechanism provided at a lower portion and for driving a vertical movement mechanism, and a method for replacing the control panel (for example, refer to Patent Document 4 below).

However, in the conventional techniques described in Patent Document 1 and Patent Document 2 described above, in order to move the new control panel to the position of the existing control panel, dedicated equipment must be used. There was a problem that the work was complicated. Further, similarly, the conventional technique described in Patent Document 3 described above is also limited to the replacement of a control panel having a dedicated housing that is supposed to be replaced, and the existing control panel that does not include such a housing is used. There was a problem that it was difficult to exchange.

Furthermore, the conventional technique described in Patent Document 3 mentioned above does not mention how to temporarily install a new control panel before connecting a new cable, and is not sufficient for practical use. There was a problem that there was. In addition, the conventional technique described in the above-mentioned Patent Document 4 is a replacement technique for a switchboard that is provided with a vertical movement mechanism and a drive mechanism in advance, and an existing control panel that does not have these mechanisms is replaced. Had the problem of being difficult.

In addition, all of the above-mentioned conventional techniques are intended to move an existing control panel upward when moving, and control in a working environment where a sufficient working space cannot be secured above the existing control panel. There was a problem that it was difficult to replace the board.

In order to solve the above-mentioned problems of the conventional technology, the present invention provides a control panel replacement method capable of smoothly and efficiently performing control panel replacement work regardless of the installation environment of an existing control panel. With the goal.

In order to solve the above-mentioned problems and to achieve the object, a control panel replacement method according to the present invention is a frame-shaped channel having a first opening for opening a top surface and a second opening for opening a bottom surface. A new control panel was temporarily installed near the existing control panel installed on the base with a predetermined space between the channel base installation surface and the channel base. A moving guide member having a guide surface positioned at the same height as the top surface of the channel base is installed at any position except between the new control board and the existing control board. A part of the first opening is moved to a position where the first opening is opened to the outside, and the cable that is routed into the channel base through the second opening is opened to the outside. After connecting to the new control panel through the opening of the cable and removing the cable connected to the existing control panel from the existing control panel, the existing control panel is removed and the first control panel is installed. The new control panel is moved to a position that closes the opening.

Further, in the control panel replacement method according to the present invention, in the above invention, the movement guide member includes a flat top surface and a bottom surface, and a length direction orthogonal to a facing direction of the top surface and the bottom surface. The plurality of independent members each having a substantially rod shape whose dimension is longer than the distance between the top surface and the bottom surface are installed in a state in which the length directions are aligned in parallel, and the existing control panel is The movement guide member is moved to a position where a part of the first opening is opened to the outside along the length direction.

Further, in the control panel replacement method according to the present invention, in the above invention, the movement guide member includes a flat top surface and a bottom surface, and a length direction orthogonal to a facing direction of the top surface and the bottom surface. With a plurality of members each having a substantially rod shape whose dimension is longer than the distance between the top surface and the bottom surface, in a state where the length directions are aligned in parallel, at least one end side in the length direction is a member connected by a connecting member.

Hereinafter, preferred embodiments of a method for replacing a control panel according to the present invention will be described in detail 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, which is the target of the control panel replacement work for replacing the existing control panel with a new control panel, has a similar configuration.

1A to 1C are explanatory views showing an example of a control panel. 1A to 1C, the control panel 100 includes a housing 101. The housing 101 has a rectangular parallelepiped (rectangular parallelepiped) shape including six rectangular surfaces. In the housing 101, the outer shapes of the surfaces facing each other have the same shape. Specifically, the outer shapes of the front surface portion and the rear surface portion, the side surface portions, and the top surface portion and the bottom surface portion are the same.

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

A door (not shown) is provided on the front surface of the housing 101 when the control panel 100 is installed on the channel base 102. The door has a substantially plate-like shape and is provided, for example, by using a hinge (not shown) or the like to close the inside of the housing 101 to the outside so as to be openable.

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

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

The channel base 102 arranged on the lower side of the housing 101 has 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. Make up. The first opening 102b and the second opening are continuous. The width dimension and the depth dimension of the channel base 102 are substantially the same as the width dimension and the depth dimension 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 replacing the control panel 100 before the last time, the depth dimension of the housing 101 of the control panel 100 before the replacement is larger than that of the control panel 100 after the replacement, and the control panel 100 before the replacement is larger. When the channel base 102 matched to the size of the housing 101 is used as it is, and the control panel 100 after replacement is installed, the depth dimension of the channel base 102 is smaller than the depth dimension of the housing 101 of the control panel 100. A long situation arises.

The control panel 100 is installed in a state of being lifted from the floor surface 130 by the height of the channel base 102 by installing the housing 101 on the channel base 102. By providing the channel base 102 between the bottom surface portion 101a of the housing 101 and the floor surface 130, the cable 104 routed from the cable processing chamber is forced to match the position of the control device 103 in the housing 101. It can be connected to the control device 103 without bending.

(Example of replacement work of 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 views showing an example of the replacement work of the control panel 100. As shown in FIG. 2, the existing control panel 100A to be replaced is arranged next to another control panel 100' next to 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 the temporary member 301 having a temporary installation surface positioned at the same height as the top surface 102a of the channel base 102.

Specifically, the temporary member 301 can be realized, for example, by a rolled steel material formed by rolling ordinary steel. More specifically, the temporary member 301 is, for example, a H-shaped steel, an I-shaped steel, a channel steel, or the like, which is a bar-shaped steel material having a length dimension larger than the cross-sectional area. It can be realized by

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 a new control panel 100B can be secured. In addition, the temporary member 301 is temporarily installed in a state where another facility or device is not interposed between the new control panel 100B and the existing control panel 100A. It is preferable that the temporary member 301 is 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 that the new control panel 100B is temporarily installed in substantially the same orientation as the existing control panel 100A. Specifically, the new control panel 100B is temporarily installed such that the door orientation of the new control panel 100B is substantially the same as the door orientation of the existing control panel 100A. As a result, the new control panel 100B is temporarily installed with the back surface of the housing 101 facing the front surface of the existing control panel 100A.

Next, the existing control panel 100A is moved. Specifically, the existing control panel 100A is moved to the back 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. 5, for example. As a result, the existing control panel 100A moves in a direction away from the new control panel 100B along the facing direction of the existing control panel 100A and the new control panel 100B.

When moving the existing control panel 100A, a movement guide member 400 for guiding the movement of the existing control panel 100A is installed as shown in FIG. 4 so that the position of the existing control panel 100A does not change in the vertical direction. To do. The movement guide member 400 has a flat top surface and a bottom surface, and has a substantially rod shape whose lengthwise dimension orthogonal to the facing direction of the top surface and the bottom surface is longer than the distance between the top surface and the bottom surface. When the existing control panel 100A is moved, the movement guide member 400 is installed on the floor surface 130 with the bottom surface thereof 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 rod-shaped steel material such as an H-shaped steel, an I-shaped steel, and a channel steel (channel) whose length dimension is larger than that of the cross-sectional area. It can be realized by a steel strip or the like.

The height dimension of the movement guide member 400 from the bottom surface to the top surface is substantially the same as the height dimension of the channel base 102. The height dimension of the movement guide member 400 from the floor surface 130 to the top surface is preferably equal to the height dimension of the channel base 102. Accordingly, by moving the existing control panel 100A along the top surface of the movement guide member 400 so that the existing control panel 100A can be slid on the top surface of the movement guide member 400, it is difficult to lift the existing control panel 100A high. The existing control panel 100A can be stably moved without significantly changing the vertical position of the control panel 100A.

The movement guide member 400 can be realized by a plurality of (for example, two) members that are independent of each other. The plurality of movement guide members 400 are installed in a state in which the length directions thereof are aligned in parallel, like rails. By using the plurality of movement guide members 400, the existing control panel 100A can be stably moved in a state in which a space is secured below the existing control panel 100A.

The existing control panel 100A is not limited to the one that is moved backward. The existing control panel 100A may be any one that moves in a direction other than the direction approaching the new control panel 100B along the facing direction of the existing control panel 100A and the new control panel 100B. Specifically, when the new control panel 100B is temporarily installed on the front side 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 diagonally forward or diagonally backward. The plurality of movement guide members 400 are, for example, at intervals equal to or smaller than the dimension of the existing control panel 100A in a direction orthogonal to the movement direction of the existing control panel 100A in the horizontal plane (hereinafter, appropriately referred to as “movement width direction”). Face each other and install in pairs.

Specifically, for example, when moving the existing control panel 100A to the back side, the width direction of the existing control panel 100A becomes the movement width direction. In this case, the paired movement guide members 400 are installed so as to face each other at intervals equal to or smaller than the width dimension of the housing 101 of the existing control panel 100A. Further, specifically, for example, when the existing control panel 100A is moved laterally, the movement direction is the depth direction of the existing control panel 100A (the direction orthogonal to the width direction in the horizontal plane). In this case, the paired movement guide members 400 are installed so as to face each other at an interval 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 at intervals equal to or smaller than the diagonal dimension of the casing 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 front surface or back surface) of the housing 101, such as the diagonal direction of the housing 101, the pair of movement guide members 400 face each other. The interval to be set differs depending on the moving direction of the existing control panel 100A. When the casing 101 of the existing control panel 100A has a rectangular shape having a depth dimension smaller than the width dimension, the distance between the pair of movement guide members 400 facing each other along the movement width direction is set to the casing of the existing control panel 100A. It can be maximized 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, a pair of movement guide members 400 is formed according to the size and movement direction of the existing control panel 100A and the surrounding conditions of the existing control panel 100A. The interval of can be adjusted arbitrarily. Thus, the existing control panel 100A can always be supported in a stable state.

In this way, unlike the conventional method, by allowing the existing control panel 100A to move in any direction, it is possible to ensure the degree of freedom in the replacement work of the control panel 100. As a result, the workability can be improved and the work efficiency can be improved as compared with the case where the existing control panel 100A is restricted in the moving direction to work in a narrow space. it 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 mounted is opened to such an extent that the cable 104 can pass therethrough. Further, the existing control panel 100A is moved to such an extent that the existing cable 104 is not sandwiched between the channel base 102 and the inner edge of the opening of the bottom surface portion 101a of the housing 101. This makes it possible to secure the cable laying route 600 for passing the cable 700 connected to the new control panel 100B, as indicated by the diagonal lines in FIG.

Then, via the secured cable laying route 600, as shown in FIG. 7, the cable 700 to be connected to the new control panel 100B is laid out from the cable processing chamber and connected. Then, 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 chamber is in a state of being 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 arrow 1000 in FIG. Specifically, as shown in FIGS. 10 and 11, a 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) between the position where the new control panel 100B is temporarily installed and the position where the existing control panel 100A is installed ( (Not shown) is installed.

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

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

The new control panel 100B moves the cable 700 connected to the new control panel 100B while pulling from the cable processing chamber side. This can prevent the cable 700 connected to the new control panel 100B from being excessively bent in the channel base 102. And thereby, 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 the movement guide member)
Next, another configuration of the movement guide member will be described. In the above-described embodiment, an example in which the paired movement guide members 400 are realized by separate and independent members has been described, 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 pair of 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 pair of movement guide members 400 can be realized by the same steel material as that of 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 connection member 1200 have a substantially U-shape.

The paired movement guide members 400 may be connected by the connecting members 1200 on both end sides in the length direction. When the paired movement guide members 400 are connected at both end sides in the longitudinal direction, the paired movement guide members 400 and the connection member 1200 have a substantially “B” shape.

In this way, the pair of movement guide members 400 are connected and integrated by the connecting member 1200, so that the distance between the pair of movement guide members 400 can be constantly maintained. As a result, it is possible to reduce the burden on the operator for installing the paired movement guide members 400. In addition, it is possible to reduce the burden on the operator for carrying the paired movement guide members 400.

In the above-described embodiment, the method of replacing the control panel 100 in which the control device 103 realized by the electromagnetic switch, the protection device, the circuit breaker, the PLC, etc. is housed 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 into a voltage according to the electrical equipment connected to the secondary side, and then distribute the voltage to a distribution panel. It can be applied to replace the board.

As described above, according to the method of exchanging the control panel 100 of the present embodiment, the predetermined control is performed between the existing control panel 100A installed on the channel base 102 and the installation surface of the channel base 102. A new control panel 100B is temporarily installed in a state where a space is secured, and the height is equal to the top surface of the channel base 102 at any position except between the channel base 102 and the temporarily installed new control panel 100B. The movement guide member 400 having the guide surface positioned at is installed.

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

According to the method of replacing the control panel 100 of the embodiment according to the present invention, by using the moving guide member 400 having the guide surface positioned at the same height as the top surface of the channel base 102, It is possible to move the existing control panel 100A that does not have a dedicated mechanism for replacement in advance, without significantly changing the 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.

According to the method of exchanging the control panel 100 of the embodiment according to the present invention, the movement guide member 400 is installed at any 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 opened to the outside, the existing control panel 100A does not have to have sufficient space around the existing control panel 100A. It is possible to connect the new control panel 100B and the cable 104 before disconnecting the connection between the cable 104 and the cable 104. As a result, it is possible to avoid that the control panel 100 cannot be used for a long time.

Further, according to the method of exchanging 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 is possible to adapt to the surrounding conditions of the existing control panel 100A. The movement guide member 400 can be installed at any position. As a result, a high degree of freedom in the replacement work of the control panel 100 can be secured, and workability can be improved.

Further, as a result, it is possible to limit the retracted position of the existing control panel 100A to only a specific place such as "only behind the existing control panel 100A" or "only in front of the existing control panel 100A". Since the replacement work of 100 can be performed, a high degree of freedom in the replacement work of the control panel 100 can be ensured, and the workability can be improved.

Further, according to the method of exchanging the control panel 100 of the embodiment of 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. Good. As a result, a new control panel 100B can be installed by using the existing channel base 102 that does not have a surplus opening for temporarily moving the existing control panel 100A as it is.

As described above, according to the method of replacing 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 installed above the existing control panel 100A. When a sufficient working space cannot be secured, the control panel 100 can be replaced smoothly and efficiently without being restricted by the working environment.

In addition, in the method of replacing the control panel 100 according to the embodiment of the present invention, the movement guide member 400 includes a flat top surface and a bottom surface, and the movement guide member 400 is provided in It is a plurality of independent members each having a substantially rod shape whose dimension is longer than the distance between the top surface and the bottom surface, and is installed in a state where the length directions thereof are aligned in parallel. It is characterized in that a part of the first opening 102b is moved along the length direction of the movement guide member 400 to a position where it is opened to the outside.

According to the method of exchanging 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 the moving direction of the existing control panel 100A.
