Embodiment 1.
FIG. 1 is a perspective view showing an arrangement member 100 for arranging a switch gear device according to the first embodiment of the present invention and its peripheral structure. FIG. 2 is a perspective view of the arrangement member 100 and the pillar L-shaped frame (pillar mounting member) 8 extracted, and FIG. 3 is a perspective view showing the housing of the switch gear. The housing is for accommodating equipment inside, and has a hexahedron (for example, a rectangular parallelepiped) framework. Among the rectangular parallelepiped frames of the housing, the frame provided on the floor surface is called the floor frame 3. Further, among the rectangular parallelepiped frames of the housing, the frame provided in the pillar portion extending in the direction orthogonal to the floor surface is referred to as a pillar frame 4. The device in the present embodiment is, for example, a circuit breaker, a transformer, a capacitor, a reactor, or the like.

The floor material provided on the floor surface of the housing according to the following embodiment will be described by taking the floor frame 3 formed on the peripheral edge of the floor surface as an example, but instead of the floor frame 3, a rectangle is used. A member (not shown) that covers the entire floor surface of the housing that bends the outer circumferences of the four sides of the metal plate in an L shape may be used.

Inside the housing of the switch gear, an arrangement member 100 for arranging the device on the upper portion is attached to the housing via the attachment structure portion. Details will be described later in FIGS. 5 and 6, but the mounting structure portion is composed of the bent portion 2b (corresponding to the engaging portion) of the width direction frame 2, the floor L-shaped frame 5, the pillar L-shaped frame 8, and the like. Will be done.

The arrangement member 100 has two depth-direction frames 1 and two width-direction frames 2. As shown in FIGS. 1 and 2, the depth direction frame 1 has a function as a scaffold for moving the device to a fixed position inside the housing.

The two width direction frames 2 are arranged so as to intersect the two depth direction frames 1, respectively, to improve the rigidity of the arrangement member 100. By fastening the fastening hole 20 of the depth direction frame 1 and the fastening hole 21 for changing the position of the width direction frame 2 with bolts or rivets (hereinafter, it may be described as "fastening with bolts or the like"), the depth direction The frame 1 and the frame 2 in the width direction are fixed.

Further, at the fixed position of the device in the depth direction frame 1, a fixing hole 13 for fixing the device housed in the switch gear is provided. In the following description, the width direction frame 2 is arranged under the depth direction frame 1, but the same effect can be obtained even if the width direction frame 2 is turned upside down. Therefore, the fixing hole 13 may be provided in the width direction frame 2.

The arrangement member 100 will be described in detail later with reference to FIGS. 6 and 7, but the floor L-shaped frame (hanging member) 5 and the pillar L-shaped frame 8 (shown in FIGS. 1 and 2) shown in FIG. 3 will be described in detail later. It is fixed to the floor frame 3 and the pillar frame 4 via.

Subsequently, the depth direction frame 1 and the width direction frame 2 will be described in more detail with reference to FIGS. 4 and 5. FIG. 4 is a perspective view showing a depth direction frame 1 which is one of the parts constituting the arrangement member 100.

The depth direction frame 1 is a frame extending in the depth direction, and has a reference surface 1a as a main surface portion. Bent portions 1b and 1c bent in a direction orthogonal to the reference surface 1a are provided at each of the end portions of the reference surface 1a facing in the width direction. The bent portion 1b and the bent portion 1c are formed by being bent in the same direction (lower side in the drawing) with respect to the reference surface 1a. In the following, "orthogonal" refers to the bent portions 1b and 1c in the case of being orthogonal in the present embodiment, but the angle of the bent portion may be less than 90 °.

Further, the bent side 1d is a side facing the bent portions 1b and 1c in the depth direction, and the bent portion 1e is provided on the bent side 1d. The bent portion 1e is formed by being bent in a direction orthogonal to the bent portions 1b and 1c (left-right direction in the figure). A fastening hole 20 is provided in the bent portion 1e. A bent portion 1f is formed on the inner side of the reference surface 1a to prevent the device with wheels from falling. The bending direction of the bent portion 1f is opposite to that of the bent portions 1b and 1c, and is the upward direction in FIG.

The depth direction frame 1 is formed with two notches at the bent portion at the end. That is, a front notch 1 g and a back notch 1 h are formed. The front side notch 1g and the back side notch 1h are notches for combining the width direction frame 2 with the depth direction frame 1.

FIG. 5 is a perspective view showing a widthwise frame 2 which is one of the parts constituting the arrangement member 100. As shown in FIG. 5, the width direction frame 2 is a frame having bent portions 2b and 2c at the four side ends of the reference surface 2a and extending in the width direction.

The bent portion 2b is bent at both ends (not shown in one direction) of the reference surface 2a in the width direction at right angles to the reference surface 2a. The bent portion 2b corresponds to the engaging portion as described later in FIGS. 6 and 7, and engages with the floor L-shaped frame (hooking member) 5 described later.

The bent portions 2c are formed at both ends of the reference surface 2a in the depth direction, and are formed by being bent with respect to the reference surface 2a in the same direction as the bent portion 2b. In other words, the bent portion 2c is formed on two opposite sides of the reference surface 2a in the depth direction, and is formed so as to be orthogonal to the reference surface 2a. Further, a fastening hole 2d is formed on the reference surface 2a of the width direction frame 2. The fastening hole 2d is a hole provided corresponding to the fastening hole 8d (described later in FIG. 7) in order to fix the pillar L-shaped frame 8 to the width direction frame 2.

A plurality of position-changing fastening holes 21 are formed in the bent portion 2c. The plurality of repositioning fastening holes 21 are arranged in the width direction so as to have a preset distance from each other. By fastening the fastening hole 20 and the position changing fastening hole 21 with bolts or the like, the depth direction frame 1 and the width direction frame 2 are fixed to each other. In the depth direction frame 1, the position of the fixed position change fastening hole 21 can be changed among the plurality of position change fastening holes 21. As a result, the width direction frame 2 can be fixed to the depth direction frame 1 at an appropriate position according to the outer shape of the device.

As described above, the widthwise frame 2 is formed with a plurality of position-changing fastening holes 21. Therefore, an appropriate position change fastening hole 21 can be selected from the plurality of position change fastening holes 21 according to the size of the device. As a result, the shape suitable for the size of the equipment to be mounted can be obtained by simply fastening the depth direction frame 1 to the width direction frame 2 by using the selected position change fastening hole 21. It is not necessary to change the configuration such as the dimensions of the width direction frame 2. Therefore, the number of operations required when changing the design can be reduced.

When the arrangement member 100 is incorporated into the housing of the switch gear, the height of the bent portion of the depth direction frame 1 and the width direction frame 2 is preferably long enough to come into contact with the floor frame 3 of the housing. .. As a result, the load applied to the arrangement member 100 by the device arranged on the arrangement member 100 can be easily dispersed.

A method of manufacturing the arrangement member 100 by combining the depth direction frame 1 and the width direction frame 2 described so far will be described. After arranging the two width direction frames 2 so as to intersect the two depth direction frames 1, the width direction frame 2 is fitted into the front side notch 1g of the two depth direction frames 1 from below the depth direction frame 1. Include. Similarly, the width direction frame 2 is also fitted into the depth side notches 1h of the two depth direction frames 1 from the lower side of the depth direction frame 1.

With this configuration, the reference surface 1a of the depth direction frame 1 and the reference surface 2a of the width direction frame 2 are arranged so that their positions in the height direction are different from each other. As a result, unlike the case where the reference surfaces 1a and 2a of both frames are arranged so as to be flush with each other, the arrangement member 100 of the present embodiment has the outer bent portion and the width of the bent portion of the depth direction frame 1. No groove is formed at the outer bent portion of the bent portion of the directional frame 2. Therefore, it is possible to avoid fitting the wheel of the device into this groove.

Hereinafter, a mounting structure portion for mounting the arrangement member 100 including the depth frame 1 and the width direction frame 2 to each frame will be described. FIG. 6 is an enlarged view of a cross section at the position AA of FIG. FIG. 7 is an enlarged exploded perspective view showing the assembly order by enlarging the portion B surrounded by the broken line shown in FIG. As described above, the mounting structure portion fixes the arrangement member 100 to the housing. In the present embodiment, the mounting structure portion is composed of a bent portion 2b (corresponding to an engaging portion) of the width direction frame 2, an floor L-shaped frame 5, and a pillar L-shaped frame 8.

As shown in FIGS. 6 and 7, the floor L-shaped frame (hanging member) 5 is a member extending in the depth direction for fixing the arrangement member 100 to the floor frame 3 and the pillar frame 4 of the housing, and is a floor. It is arranged along the frame 3, and the cross-sectional shape of the floor L-shaped frame 5 is, for example, L-shaped. The floor L-shaped frame (hooking member) 5 is provided on each of the two opposing sides of the floor surface of the housing. The above-mentioned cross-sectional shape is a cross-sectional shape in a plane perpendicular to the extending direction (depth direction) of the floor L-shaped frame 5.

Here, the structure of the floor L-shaped frame 5 will be described in detail. The floor L-shaped frame 5 has a convex portion 5a protruding upward with respect to the floor surface of the housing, and a base portion 5c fixed to the floor surface of the housing.

The convex portion 5a of the floor L-shaped frame 5 extends in the depth direction along the opposite sides of the floor surface of the housing. Both ends of the convex portion 5a in the depth direction are fixed to the pillar frame 4. In the present embodiment, the convex portion 5a of the floor L-shaped frame 5 extends in the depth direction along two opposite sides in the width direction of the floor frame 3, but in the depth direction of the floor frame 3. It may be configured to extend in the width direction along two opposing sides. That is, the convex portion 5a of the floor L-shaped frame 5 extends from the front to the back along the two sides of the floor frame 3 facing each other in the depth direction or the width direction. Here, the above-mentioned "front surface" is the front surface shown in FIG. 1, that is, one surface facing the depth direction of the housing when the convex portion 5a of the floor L-shaped frame 5 extends in the depth direction of the floor frame 3. Corresponds to. Further, when the convex portion 5a of the floor L-shaped frame 5 extends in the width direction of the floor frame 3, the "front surface" corresponds to one surface facing the width direction of the housing.

The base portion 5c is integrally formed at the lower end of the convex portion 5a and is bent in a direction orthogonal to the convex portion 5a. Further, the floor L-shaped frame 5 is fixed to the floor frame 3 by the convex portion 5a and the base portion 5c.

With such a configuration, the load applied to the arrangement member when mounting the device is fixed to the pillar frame 4 of the housing and the floor frame 3 integrally by using the floor L-shaped frame 5 in this way, so that the pillar frame of the housing is used. 4. The floor material including the floor frame 3 and the floor L-shaped frame 5 (hooking member) can be dispersed, and the load of the equipment can be suppressed from being concentrated on the floor material such as the floor frame 3. Therefore, high strength can be realized without welding, assembly workability is high, and a floor surface structure with high strength can be realized.

The cross-sectional shape of the floor L-shaped frame 5 attached to the housing may be U-shaped (U-shaped) in addition to L-shaped. Further, in order to obtain the effect of load distribution as described above, the floor L-shaped frame (hooking member) may have a convex portion for hooking and fixing the bent portion 2b of the width direction frame 2. The convex portion 5a can be directly attached to the floor frame 3 except for the base portion 5c. Further, in the above configuration, the bent portion 2b of the width direction frame 2 as the engaging portion is formed so as to be orthogonal to the reference surface 2a in the downward direction, but the bent portion corresponds to the hooking member. Needless to say, the bending angle of the song may be changed. Further, as long as the shape allows contact with the hooking member in a sufficient area, the shape may be other than bending.

The floor L-shaped frame 5 may be omitted, and the convex portion of the floor frame 3 may be used as a hooking member for the bent portion 2 of the width direction frame 2. In this case, the bent portion 2b of the width direction frame 2 engages with the convex portion of the floor frame 3. Since the floor L-shaped frame 5 can be omitted, the configuration of the mounting structure portion can be simplified.

Next, the pillar L-shaped frame 8 will be described in detail. The pillar L-shaped frame 8 is a member that integrally fixes the arrangement member 100 to the pillar frame 4 of the housing. The cross-sectional shape of the pillar L-shaped frame 8 is, for example, L-shaped and extends in the depth direction of the housing. One portion 8a of the pillar L-shaped frame 8 extending in the depth direction is fixed to the pillar frame 4. Further, the other portion 8c orthogonal to or intersecting one portion 8a is fixed to the reference surface 2a of the width direction frame 2.

By providing the pillar L-shaped frame 8, it is possible to improve the effect of distributing the weight of the device applied to the arrangement member 100 to the pillar frame 4. The pillar L-shaped frame 8 may be U-shaped (U-shaped) like the floor L-shaped frame 5. Further, even if the switch gear is configured without providing the pillar L-shaped frame 8, the effect of load distribution is reduced, but a sufficient effect can be obtained.

As for the method of fastening and fixing the floor frame 3 and the floor L-shaped frame 5, rivets, bolts and the like are used, and the pillar L-shaped frame 8 and the pillar frame 4 are fastened and fixed in the same manner.

Here, the assembly order in which the arrangement member 100 is attached to the housing of the switch gear will be described with reference to FIGS. 6 and 7.

First, the floor L-shaped frame 5 is fixed to the floor frame 3 and the pillar frame 4. The pillar frame 4 and the floor L-shaped frame 5 are fixed to each other by fastening the fastening holes 5b formed in the convex portion 5a of the L-shaped frame 5 to the fastening holes 4b of the pillar frame 4 with bolts or the like. The floor frame 3 and the floor L-shaped frame 5 are fixed to each other by fastening with bolts or the like in the fastening holes 5d and the fastening holes 3a.

Next, the two depth direction frames 1 and the two width direction frames 2 are assembled outside the housing to manufacture the arrangement member 100.

Subsequently, the arrangement member 100 is attached to the housing of the switch gear. Here, when the arrangement member 100 is attached to the housing of the switch gear, the bent portion 2b of the width direction frame 2 is hooked on the convex portion 5a of the floor L-shaped frame 5. As described above, when the arrangement member 100 is incorporated into the housing, the end portion of the arrangement member 100 is incorporated so as to be hooked on the floor L-shaped frame 5 of the housing, and the arrangement member 100 is fastened to the housing with bolts or the like. Assembling workability is good because it only needs to be fixed.

Next, the column frame 4 and the column L-shaped frame 8 are fixed to each other by fastening the fastening holes 4a and the fastening holes 8b with bolts or the like. Further, the pillar L-shaped frame 8 and the widthwise frame 2 are fixed to each other by fastening the fastening hole 8d and the fastening hole 2d with bolts or the like.

Note that FIGS. 6 and 7 show the left end on the back side of the housing, and the right end on the back side of the housing as well as the left end on the back side has a shape symmetrical to that in FIG. It is a structure that hooks on 5. Further, the front right end and the front left end of the housing also have the same structure as the back right end and the back left end, respectively.

Further, by making the arrangement member 100 a rail structure, all the arrangement members 100 can be assembled externally. Therefore, when the arrangement member 100 is put into the housing, the end portion of the arrangement member 100 is assembled so as to be hooked on the floor L-shaped frame 5. Then, by fixing the pillar frame 4 of the housing and the arrangement member 100 with bolts or the like via the pillar L-shaped frame 8, the floor structure of the switch gear can be configured. As a result, even if the arrangement member 100 has a rail structure for the purpose of improving the strength and rigidity of the floor structure of the switch gear, the assembly workability does not deteriorate.

FIG. 8 is a perspective view showing a modified example of the depth direction frame 1. In the present embodiment, by configuring the depth direction frame 1 as shown in FIG. 4 described above, the possibility that the wheels of the device will be fitted into the groove is reduced. On the other hand, when the mass of the device is relatively small and the wheels are difficult to fit between the two frames, the depth direction frame may be configured as shown in FIG. That is, the bent portion 6b is formed at the end portion of the reference surface 6a in the depth direction frame 6 in the depth direction, and the bent portion 6c is formed at the end portion in the width direction of the reference surface 6a. Further, fastening holes 6d are provided in the bent portions 6b at both ends of the depth direction frame 6 in the depth direction. The width direction frame 2 and the depth direction frame 6 are fixed to each other by bolting the fastening hole 6d of the depth frame 6 and the position change fastening hole 21 (FIG. 5) of the width direction frame 2.

In the present embodiment, the configuration in which the depth direction frame 1 and the width direction frame 2 are provided by two each is described as an example, but the present invention is not limited to two, and the depth direction constituting the arrangement member 100 is not limited to two. The same effect can be obtained by appropriately increasing or decreasing the number of frames 1 and the number of frames 2 in the width direction.

Further, in the above description, the arrangement member 100 has a rail structure in which two depth direction frames 1 are arranged in parallel, but the arrangement member may be formed by a flat plate or the like. In particular, when a device having no wheels is mounted, the arrangement member 100 does not need to have a rail structure, so the arrangement member may be configured by two widthwise frames 2. In this case, the depth direction frame 1 can be omitted by arranging the width direction frame 2 according to the fastening pitch of the device.

In the switch gear according to the present invention, the load applied to the arrangement member 100 when mounting the device can be distributed to the pillar frame 4, the engaging portion, and the hooking member of the housing. As a result, it is possible to suppress the concentration of the load of the equipment on the floor material.

Embodiment 2.
When the arrangement member 100 of the first embodiment is used, the positions of the fixing holes 13 for fixing the equipment in the depth direction frame 1 in the depth direction (hereinafter, referred to as “fixing hole positions”) are two width direction frames 2. It may overlap with one or both. In this case, in addition to the depth direction frame 1, it is necessary to form holes in one or both of the two width direction frames 2, and the types of frames to be manufactured increase.

Therefore, in order to reduce the types of frames to be manufactured in the present embodiment, first, a depth direction frame having at least four types of different notch positions including the depth direction frame 1 shown in FIG. 4 is prepared. Next, the depth direction frame to be used is changed according to the fixing position of the device so that the fixing hole position in the depth direction frame does not overlap with the width direction frame 2.

Hereinafter, the shapes of the three types of depth direction frames 9, 11, and 12 other than the depth direction frame 1 will be described with reference to FIGS. 9 to 14. In the following embodiment, two width direction frames 2 are used, and the front side and back side width direction frames will be described separately from the width direction frame 2X and the width direction frame 2Y, respectively.

FIG. 9 is a perspective view showing a part of the housing of the arrangement member 100 and the switch gear according to the second embodiment of the present invention. FIG. 10 is a perspective view showing a depth direction frame 9 of the arrangement member 100 according to the second embodiment of the present invention. The depth direction frame 9 of the present embodiment is different from the depth direction frame 1 of the first embodiment in the notch position of the bent portion formed at the end portion of the depth direction frame 9.

The depth direction frame 9 shown in FIGS. 9 and 10 has two notches at the bent portions formed at the ends thereof, and is referred to as a front notch 9g and a back notch 9h. The front side notch 9 g is the same as the front side notch 1 g shown in FIG. On the other hand, the depth side notch 9h is different from the depth side notch 1h in that it is formed on the front side by the length of the width direction frame 2Y in the depth direction or more. On the back side of the back side notch 9h, a bent portion 9c having a surface bent in a direction orthogonal to the bent side 9b is provided. A fastening hole 22 for fixing the bent portion 9c together with the width direction frame 2Y is formed. Further, the pillar L-shaped frame 8 for fixing the width direction frames 2X and 2Y to the housing is provided with a fastening hole 8d in advance. The fastening hole 8d is formed corresponding to the position of the width direction frames 2X and 2Y in the depth direction.

FIG. 11 is a perspective view showing a part of a modified example of the arrangement member and the switch gear according to the second embodiment of the present invention. FIG. 12 is a perspective view of the depth direction frame 11 shown in FIG.

The depth direction frame 11 shown in FIGS. 11 and 12 has two notches at the bent portions formed at the ends thereof, and is referred to as a front notch 11g and a back notch 11h. The depth notch 11h of the depth direction frame 11 has the same notch position as the depth notch 1h (FIG. 4) of the depth direction frame 1. On the other hand, the front side notch 11g of the depth direction frame 11 is equal to or more than the length of the width direction frame 2X in the depth direction, and is closer to the back side in the drawing than the front side notch 1g (FIG. 4) of the depth direction frame 1. It differs in that it is formed.

FIG. 13 is a perspective view showing a part of another modification of the arrangement member and the switch gear according to the second embodiment of the present invention. In the depth direction frame 12 shown in FIGS. 13 and 14, the fastening positions of the width direction frame 2X on the front side and the width direction frame 2Y on the back side are deeper than the fastening positions of the width direction frame 2 shown in FIG. It is moving to the side and the front side, respectively.

Similar to the depth direction frame 11, the depth direction frame 12 has two notches at each of the bent portions formed at the end portions thereof, and is referred to as a front side notch 12g and a back side notch 12h. The front side notch 12g of the depth direction frame 12 is formed on the back side in the drawing by the length of the width direction frame 2X or more in the depth direction as compared with the front side notch 1g of the depth direction frame 1 shown in FIG. .. Further, the depth side notch 12h of the depth direction frame 12 is formed on the front side by the length of the width direction frame 2Y or more in the depth direction as compared with the depth side notch 1h of the depth direction frame 1.

In the present embodiment, since it is only necessary to change the shape of the frame in the depth direction among the arranged members, the number of operations at the time of design change can be reduced. Even when the shape of the depth direction frame is changed, four types of depth direction frames shown in FIGS. 4, 10, 12, and 14 are prepared, and one of these four types is selected and then arranged. The position of the fixing hole 13 in the depth direction frame of the member is simply changed according to the shape of the device. As a result, the number of operations required when the dimensions of the device are changed can be significantly reduced.

FIG. 16 is a perspective view showing a widthwise frame 14 according to a third embodiment of the present invention. FIG. 17 is a cross-sectional view taken along the line CC of FIG. FIG. 18 is an enlarged exploded perspective view showing the assembly order by enlarging the portion D surrounded by the broken line shown in FIG.

In FIG. 15, the arrangement member of the present embodiment is different from the first embodiment in that the column L-shaped frame 8 is omitted and the column frame 4, the floor L-shaped frame 15, and the width direction frame 14 are fixed together. ..

As shown in FIG. 16, in the width direction frame 14 of the present embodiment, fastening holes 14b and 14c are formed in bent portions 14a formed on both sides in the width direction.
