Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage battery mount or storage box.

[0002]

2. Description of the Related Art There have been proposed various types of storage battery mounts and storage boxes.

For example, Japanese Utility Model Laid-Open Publication No. 2-49065 discloses a structure in which the columns are connected by beams, and a battery frame for receiving a storage battery is provided between the beams. The connection between the columns and the beams is generally welded.

[0004] Since the storage battery gantry or storage box is manufactured by welding between the columns and the beams, when the storage battery is installed in a place where the carrying path is narrow, the gantry or the storage box is individually arranged so as not to interfere with the carrying path. Had to be designed.

[0005] In addition, the gantry or the storage box requires a transportation space for transporting the product in a large-volume finished product state.
This was a factor that increased transportation costs. In this regard, it is conceivable to perform welding assembly work at the installation site,
Due to restrictions on the use of fire, etc., it was difficult to actually perform the assembly work at the installation site.

[0006] On the other hand, the structure in which the column and the beam are joined by bolts has a weaker joint strength than the welded structure, and in particular, there is a case where the strength is insufficient in the case of the frame for loading a heavy storage battery as in the present invention. there were.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to provide a storage battery mount which can be easily assembled at an installation place without using assembling means by welding as in the conventional mount described above. As a result, the gantry design is not restricted by the carry-in route to the installation location. In addition, since it can be transported in a disassembled state, the volume at the time of transportation can be minimized and the transportation cost can be reduced. In addition, it is possible to provide a storage battery mount and a storage box having sufficient strength.

[0008]

According to a first aspect of the present invention, there is provided a frame for a storage battery having a column and a beam connected to the column. The beam is connected to the beam with a bolt via a bracket, and at the connection surface between the bracket and the support or the beam, the bracket is provided with a convex portion or a concave portion close to a bolt hole of the bolt, and the convex portion is formed on the bracket. A corresponding fitting concave portion or a fitting convex portion corresponding to the concave portion is provided on the column or the beam.

According to a second aspect of the present invention, in the storage battery frame having the structure of the first aspect, a plurality of uneven portions are provided, and a bolt connecting portion is connected to the plurality of uneven portions. It was configured to be located on the line.

According to a third aspect of the present invention, a top plate, a bottom plate, and a side plate are connected to columns and beams of a storage battery mount having the configuration of the first or second aspect to form a storage battery storage box. .

[0011]

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a storage battery mount 1 according to the present invention.

The battery frame 1 has a structure in which four vertically positioned columns 2 are connected to beams 4 and 5 via brackets 3. A receiving angle 6 on which a storage battery (not shown) is mounted is connected to the support 2 at a predetermined interval.

FIG. 2 is a perspective view showing a bracket 3 used for a joint between the column 2 and the beam 4.

The bracket 3 has an L-shape with two coupling surfaces 3a coupled at one end thereof, and a right-angled triangular reinforcing piece 3b is coupled to a side of the coupling surface 3a.

The coupling surface 3a has a bolt hole 7 and a projection 8 in the vicinity thereof. The protrusion 8 is formed by extruding from the inside of the bracket 3. According to such a configuration, the protrusion 8 can have strength by a relatively simple method.

FIG. 3 is a sectional view showing a state where the bracket 3 and the beams 4 and 5 are connected. The beams 4 and 5 have a hollow quadrangular prism shape formed by bending a rolled steel material. With the beams 4, 5 and the coupling surface 3a of the bracket 3 in close contact with each other, the projection 8 of the coupling surface 3a is fitted into a concave portion or coupling hole 9 provided in the beams 4,5. The beams 4 and 5 and the bracket 3 are connected by bolts 10 and nuts 11 through bolt holes 7. Thus, even if the beams 4 and 5 and the columns 2 are displaced by the load of the storage battery (not shown), the stress is not concentrated on the bolts 10 and the nuts 11 and sufficient strength can be secured. Also, a clip nut or nut 11 is welded to the inside of a bolt insertion hole 12 provided in the beam 4, 5, and the bracket 3 and the beam 4, 5 are bolted into the bolt hole 7 of the bracket 3 and the bolt 4, 5. The beam 4 and the beam 5 or the beam 4,
5 and the strut 2 are configured to prevent the lateral displacement. Also,
Bolts 10 are provided inside bolt insertion holes 12 provided in beams 4 and 5.
Spirals can be formed.

A plurality of projections 8 are provided,
Position the bolt 10 on the line connecting them, that is,
By arranging the projection 8-the bolt 10-the projection 8 on a straight line, it is possible to effectively receive the load generated by the load or vibration of the storage battery.

As described above, since all the columns and beams can be connected by one kind of bracket, the manufacturing cost can be reduced, and the assembling of the gantry or the storage box can be facilitated. Further, since the gantry or the storage box can be disassembled and transported in the minimum space, the transportation cost can be reduced.

FIG. 4 is a perspective view showing a state in which the beams 4 and 5 are connected to the support 2. The bracket 3 is disposed at a corner formed by the column 2 and the beams 4 and 5. With such a configuration, the column 2 and the beams 4 and 5 can be securely connected without using a welding method.

FIG. 5 shows a front door 1 on the storage battery base shown in FIG.
3 is a perspective view of a storage box for a storage battery configured by attaching a side plate 14 and a ceiling plate 15.

Further, it is needless to say that a recess or a through hole may be used instead of the projection 8 of the bracket 3, and in this case, the projection may be provided on the support and the beam.

[0023]

According to the present invention, it is possible to obtain a configuration of a storage battery mount that can be easily assembled at an installation place without using welding. As a result, the gantry design is not restricted by the carry-in route to the installation location. In addition, since it can be transported in a disassembled state, the volume at the time of transportation can be minimized and the transportation cost can be reduced. In addition, it is possible to provide a storage battery mount and a storage box each having sufficient strength.
