Embodiment 1 FIG.
FIG. 1 is a perspective view showing an arrangement member 100 for arranging a switchgear device according to Embodiment 1 of the present invention and its peripheral structure. FIG. 2 is a perspective view in which the arrangement member 100 and the L-shaped frame (post mounting member) 8 are extracted, and FIG. 3 is a perspective view showing a switchgear housing. The casing is for housing equipment therein and has a hexahedral (for example, rectangular parallelepiped) frame. Of the rectangular parallelepiped frame, the frame provided on the floor is referred to as a floor frame 3. Moreover, the frame provided in the pillar part extended in the direction orthogonal to a floor surface among the frame bodies of a rectangular parallelepiped of a housing is called the pillar frame 4. FIG. In addition, the apparatus in this Embodiment is a circuit breaker, a transformer, a capacitor | condenser, a reactor etc., for example.

  In addition, about the floor surface material provided in the floor surface of the housing of the following embodiments, the floor frame 3 formed on the periphery of the floor surface will be described as an example, but instead of the floor frame 3, a rectangular shape is used. You may use the member (illustration omitted) which covers the whole floor surface of the housing which bends the outer periphery of the four sides of this metal plate into L shape.

  Inside the switchgear housing, a placement member 100 for placing equipment on the top is attached to the housing via a mounting structure portion. Although details will be described later with reference to FIGS. 5 and 6, the mounting structure portion includes a bent portion 2 b (corresponding to the engaging portion) of the width direction frame 2, a floor L-shaped frame 5, a pillar L-shaped frame 8, and the like. Is 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 with the two depth direction frames 1 respectively, and the rigidity of the arrangement member 100 is improved. By fastening the fastening hole 20 of the depth direction frame 1 and the fastening hole 21 for position change of the width direction frame 2 with a bolt or a rivet (hereinafter sometimes referred to as “fastening with a bolt or the like”), the depth direction The frame 1 and the width direction frame 2 are fixed.

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

  The arrangement member 100 will be described later in detail with reference to FIGS. 6 and 7, but the floor L-shaped frame (hook member) 5 and the pillar L-shaped frame 8 illustrated in FIG. 3 (illustrated in FIGS. 1 and 2). 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 the depth direction frame 1 which is one of the components 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. Each of the end portions facing the width direction of the reference surface 1a is provided with bent portions 1b and 1c that are bent in a direction orthogonal to the reference surface 1a. The bent portion 1b and the bent portion 1c are formed by being bent in the same direction (lower side in the figure) with respect to the reference surface 1a. In the following description, “perpendicular” indicates the bent portions 1b and 1c in the present embodiment as an example of a case where they are orthogonal, but the angle of the bent portions may be less than 90 °.

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

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

  FIG. 5 is a perspective view showing the width direction frame 2 that is one of the components constituting the arrangement member 100. As shown in FIG. 5, the width direction frame 2 is a frame that has bent portions 2 b and 2 c at the ends of the four sides of the reference surface 2 a and extends in the width direction.

The bent portion 2b is bent at both ends (one direction is not shown) in the width direction of the reference surface 2a so as to be orthogonal to the reference surface 2a. In addition, this bending part 2b respond | corresponds to an engaging part so that it may mention later in FIG. 6, 7, and it engages with the floor L-shaped frame (hook member) 5 mentioned later.

The bent portions 2c are formed at both end portions in the depth direction of the reference surface 2a, and are formed by being bent in the same direction as the bent portions 2b with respect to the reference surface 2a. In other words, the bent portion 2c is formed on two sides facing each other in the depth direction of the reference surface 2a, and is formed so as to be orthogonal to the reference surface 2a. Further, a fastening hole 2 d is formed in the reference surface 2 a 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 column 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 position changing fastening holes 21 are arranged in the width direction so as to have a predetermined interval. The depth direction frame 1 and the width direction frame 2 are fixed to each other by fastening the fastening hole 20 and the position changing fastening hole 21 with a bolt or the like. The depth direction frame 1 is capable of changing the position of the position changing fastening holes 21 among the plurality of position changing fastening holes 21. Thereby, 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, a plurality of position changing fastening holes 21 are formed in the width direction frame 2. Therefore, an appropriate position changing fastening hole 21 can be selected from the plurality of position changing fastening holes 21 according to the size of the device. Thereby, it can be set as the shape suitable for the magnitude | size of the apparatus attached only by fastening the depth direction frame 1 to the width direction frame 2 using this selected position change fastening hole 21, and the depth direction frame 1 and There is no need 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 assembled in the switchgear casing, the heights of the bent portions of the depth direction frame 1 and the width direction frame 2 are preferably long enough to contact the floor frame 3 of the casing. . Thereby, about the load which the apparatus arrange | positioned on the arrangement | positioning member 100 gives to the arrangement | positioning member 100, dispersion | distribution of this load becomes easy.

  A method for producing 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 notch 1g on the near side of the two depth direction frames 1 from below the depth direction frame 1. Include. Similarly, the width direction frame 2 is fitted into the depth notches 1 h 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. Thus, 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 an outer bent portion and a 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 direction frame 2. Therefore, it is possible to avoid fitting of the wheel of the device into this groove.

  Hereinafter, the attachment structure part which attaches the arrangement | positioning member 100 which consists of the depth frame 1 and the width direction frame 2 to each frame is demonstrated. FIG. 6 is an enlarged view of a cross section at the position AA in FIG. FIG. 7 is an enlarged exploded perspective view showing an assembly sequence by enlarging a portion B surrounded by a broken line shown in FIG. The mounting structure portion fixes the arrangement member 100 to the housing as described above. In the present embodiment, the attachment structure portion includes a bent portion 2b (corresponding to the engaging portion) of the width direction frame 2, a 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 column frame 4 of the frame. The cross-sectional shape of the floor L-shaped frame 5 arranged along the frame 3 is, for example, L-shaped. The floor L-shaped frame (hanging member) 5 is provided on each of two opposing sides of the floor surface of the housing. In addition, the above-mentioned cross-sectional shape is a cross-sectional shape in a plane perpendicular to the direction (depth direction) in which the floor L-shaped frame 5 extends.

  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 that protrudes upward with respect to the floor surface of the housing, and a base portion 5c that is fixed to the floor surface of the housing.

  The convex part 5a of the floor L-shaped frame 5 extends in the depth direction along opposite sides of the floor surface of the housing. Both ends in the depth direction of the convex portion 5 a are fixed to the column frame 4. In the present embodiment, the convex portion 5 a of the floor L-shaped frame 5 is configured to extend in the depth direction along two sides facing each other in the width direction of the floor frame 3, but in the depth direction of the floor frame 3. The structure may be extended in the width direction along two opposing sides. That is, the convex part 5a of the floor L-shaped frame 5 extends from the front surface to the back along the two sides on the two sides of the floor frame 3 facing each other in the depth direction or the width direction. Here, when the convex part 5a of the floor L-shaped frame 5 extends in the depth direction of the floor frame 3, the “front surface” described above is the one surface that faces the front surface shown in FIG. Corresponding to 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 5c is formed integrally with the lower end of the convex portion 5a and is bent in a direction perpendicular to the convex portion 5a. Further, the floor L-shaped frame 5 is fixed to the floor frame 3 by a convex portion 5a and a base portion 5c.

  With such a configuration, the load applied to the arrangement member when the device is mounted is fixed to the housing column frame 4 and the floor frame 3 as one body by using the floor L-shaped frame 5 as described above, thereby 4. It can disperse | distribute to the floor surface material containing the floor frame 3, and the floor L-shaped frame 5 (hanging member), and can suppress that the load of an apparatus concentrates on floor surface materials, such as the floor frame 3. Accordingly, a high strength can be realized without welding, and a floor structure with high assembling workability and 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 the L-shaped. Further, in order to obtain the effect of load distribution as described above, the floor L-shaped frame (hanging member) only needs to have a convex portion for hooking and fixing the bent portion 2b of the width direction frame 2. The convex part 5a can be directly attached to the floor frame 3 except for the base part 5c. In the above-described configuration, the bent portion 2b of the width direction frame 2 as the engaging portion is formed to be orthogonal to the lower direction with respect to the reference surface 2a. Needless to say, the bending angle and the like may be changed. Moreover, if it is a shape which can contact a hook member with sufficient area, it can also be set as shapes other than bending.

  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 by omitting the floor L-shaped frame 5. In this case, the bent portion 2 b of the width direction frame 2 is engaged 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 column L-shaped frame 8 is a member for fixing the arrangement member 100 to the column column 4 of the housing as a unit. The cross-sectional shape of the columnar L-shaped frame 8 is, for example, L-shaped and extends in the depth direction of the housing. One portion 8 a of the pillar L-shaped frame 8 extending in the depth direction is fixed to the pillar frame 4. In addition, the other portion 8 c that is orthogonal to or intersects with the one portion 8 a is fixed to the reference surface 2 a of the width direction frame 2.

  By providing the column L-shaped frame 8, it is possible to improve the effect of dispersing the weight of the device applied to the arrangement member 100 to the column frame 4. The column L-shaped frame 8 may be U-shaped (U-shaped) like the floor L-shaped frame 5. Even if the switchgear is configured without providing the column 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 fastening of the column L-shaped frame 8 and the column frame 4 is similarly performed.

  Here, the assembly sequence for attaching the arrangement member 100 to the switchgear housing will be described with reference to FIGS.

  First, the floor L-shaped frame 5 is fixed to the floor frame 3 and the pillar frame 4. By fastening the fastening hole 5b formed in the convex portion 5a of the L-shaped frame 5 to the fastening hole 4b of the pillar frame 4 with a bolt or the like, the pillar frame 4 and the floor L-shaped frame 5 are fixed to each other. 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 assembly of the two depth direction frames 1 and the two width direction frames 2 is performed outside the housing, and the arrangement member 100 is manufactured.

  Subsequently, the arrangement member 100 is attached to the casing of the switch gear. Here, when the arrangement member 100 is attached to the switchgear housing, the bent portion 2 b of the width direction frame 2 is hooked on the convex portion 5 a of the floor L-shaped frame 5. As described above, when the arrangement member 100 is incorporated into the housing, the arrangement member 100 is assembled so that the end of the arrangement member 100 is hooked on the floor L-shaped frame 5 of the housing, and the arrangement member 100 is fastened to the housing with a bolt or the like. Since it is only necessary to fix it, assembly workability is good.

  Next, by fastening the fastening hole 4a and the fastening hole 8b with a bolt or the like, the column frame 4 and the column L-shaped frame 8 are fixed to each other. Furthermore, the columnar L-shaped frame 8 and the width direction frame 2 are fixed to each other by fastening the fastening hole 8d and the fastening hole 2d with a bolt or the like.

  6 and 7 show the rear left end portion of the housing, and the rear right end portion of the housing is symmetric with FIG. 6 in the same manner as FIG. 5 is a structure to be hooked. 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.

  Furthermore, the arrangement | positioning member 100 can be assembled outside by making the arrangement | positioning member 100 into a rail structure. Therefore, when placing the arrangement member 100 into the housing, the arrangement member 100 is assembled so that the end of the arrangement member 100 is hooked on the floor L-shaped frame 5. And the floor surface structure of a switch gear can be comprised by fixing the pillar frame 4 and arrangement | positioning member 100 of a housing | casing with a volt | bolt etc. via the pillar L-shaped flame | frame 8. FIG. As a result, the assembly workability does not deteriorate 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 switchgear.

  FIG. 8 is a perspective view showing a modification of the depth direction frame 1. In the present embodiment, as shown in FIG. 4 described above, the depth direction frame 1 is configured to reduce the possibility that the wheels of the equipment will fit into the grooves. On the other hand, when the mass of the device is relatively small and the wheel is difficult to fit between the frames, the depth direction frame may be configured as shown in FIG. That is, the bent portion 6b is formed at the end in the depth direction of the reference surface 6a in the depth direction frame 6, and the bent portion 6c is formed at the end in the width direction of the reference surface 6a. Furthermore, the fastening holes 6d are provided in the bent portions 6b at both ends in the depth direction of the depth direction frame 6. 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 changing fastening hole 21 (FIG. 5) of the width direction frame 2.

  In the present embodiment, the configuration in which two depth direction frames 1 and two width direction frames 2 are provided has been described as an example. However, 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 the frames 1 and the width direction frames 2 respectively.

  In the above description, the arrangement member 100 has a rail structure in which the two depth direction frames 1 are arranged in parallel. However, the arrangement member may be configured by a flat plate or the like. In particular, when a device that does not have wheels is mounted, the arrangement member may be configured by the two width direction frames 2 because the arrangement member 100 does not need to have a rail structure. In this case, the depth direction frame 1 can be omitted by arranging the width direction frame 2 in accordance with the fastening pitch of the device.

  In the switchgear according to the present invention, the load applied to the arrangement member 100 when the device is mounted can be distributed to the column frame 4, the engaging portion, and the hooking member of the housing. Thereby, concentration of the load of the apparatus with respect to a floor surface material can be suppressed.

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

  Therefore, in the present embodiment, in order to reduce the types of frames to be manufactured, first, depth direction frames having at least four different cutout positions including the depth direction frame 1 shown in FIG. 4 are prepared. Next, the depth direction frame used according to the fixing position of the device is changed 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 are 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 Embodiment 2 of the present invention. FIG. 10 is a perspective view showing the depth direction frame 9 of the arrangement member 100 according to Embodiment 2 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 of the depth direction frame 9.

  The depth direction frame 9 shown in FIGS. 9 and 10 has two cutouts at the bent portions formed at the end portions thereof, which are referred to as a front side cutout 9g and a backside cutout 9h. The front notch 9g is the same as the front notch 1g shown in FIG. On the other hand, the rear side notch 9h is different from the rear side notch 1h of the depth frame 1 in that it is formed on the near side more than the length of the width direction frame 2Y in the depth direction. A bent portion 9c having a surface bent in a direction orthogonal to the bent side 9b is provided on the inner side of the rear notch 9h. A fastening hole 22 for fixing together with the width direction frame 2Y is formed in the bent portion 9c. Furthermore, a fastening hole 8d is provided in advance in the column L-shaped frame 8 for fixing the width direction frames 2X and 2Y to the housing. The fastening holes 8d are formed corresponding to positions in the depth direction of the width direction frames 2X and 2Y.

  FIG. 11 is a perspective view showing a part of a modification of the arrangement member and the switch gear according to Embodiment 2 of the present invention. 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 cutouts at the bent portions formed at the end portions thereof, which are referred to as a front cutout 11g and a deep cutout 11h. The depth-side notch 11h of the depth direction frame 11 has the same notch position as the depth-side 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 more than the length of the width direction frame 2X in the depth direction compared to the front side notch 1g of the depth direction frame 1 (FIG. 4). It differs in that it is formed.

  FIG. 13 is a perspective view showing a part of another modified example of the disposing member and the switch gear according to Embodiment 2 of the present invention. In the depth direction frame 12 shown in FIGS. 13 and 14, the fastening position of the front side width direction frame 2X and the back side width direction frame 2Y is respectively farther than the fastening position of the width direction frame 2 shown in FIG. It has moved to the side and the near side respectively.

  Similarly to the depth direction frame 11, the depth direction frame 12 has two cutouts at the bent portions formed at the ends thereof, which are referred to as a front side cutout 12 g and a back side cutout 12 h. The front side notch 12g of the depth direction frame 12 is formed on the back side in the drawing by a length equal to or longer than the width direction frame 2X in the depth direction, compared to 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 more than the depth-direction notch 1h of the depth-direction frame 1 by the length of the width-direction frame 2Y in the depth direction.

  In the present embodiment, it is only necessary to change the shape of the depth direction frame in the arrangement member, so that the number of operations at the time of design change can be reduced. Even when the shape of the depth direction frame is changed, the four types of depth direction frames of FIGS. 4, 10, 12, and 14 are prepared, and one of these four types is selected, and then arranged. It is only necessary to change the position of the fixing hole 13 in the depth direction frame of the member in accordance with the shape of the device. Thereby, when the dimension of an apparatus is changed, the number of work required can be reduced significantly.
