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 on which a plurality of storage batteries, such as industrial cathode absorption lead storage batteries, to be used as an assembled battery are arranged vertically and horizontally.

[0002]

2. Description of the Related Art There are two types of mounts of this type: a vertical type in which a storage battery is mounted in an upright state, a horizontal type in which a storage battery is mounted in a sideways state, and There is a tilt type that is mounted in a state of being tilted greatly.

[0003] In the case of a vertical type stand on which a storage battery is placed in an upright state, it is necessary to secure a space for maintenance and inspection above the terminals of the placed storage battery, and also to perform a construction and inspection work on the side of the stand. However, there is a problem that the space efficiency at the time of installation of the gantry is deteriorated because a worker area for workers must be secured.

[0004] On the other hand, in the case of a stand of a horizontal or inclined installation type in which the inclination angle is large, the terminal portion of the storage battery mounted on the base faces the front side of the mount, so that the space for maintenance and inspection of the storage battery and the construction work are required. The inspection worker area is on the front side of the gantry.

[0005]

When installing a storage battery mount, the area for construction inspection workers is required by law to have a width of 600 mm or more in front of the mount, but generally, a storage battery mount is provided. Is often set to the lower limit of 600 mm because of its installation in a narrow space. The area for the inspection worker overlaps, and the terminal of the storage battery, which is the target for maintenance and inspection, is almost in front of the worker located in the area for the construction inspection worker. At present, it is difficult to work.

[0006] On the other hand, in the case of a horizontal installation or an inclination installation with a large inclination angle, when a horizontal force is applied due to an earthquake or the like, there is a danger that the storage battery may jump out or fall to the front side of the gantry. For this reason, the terminal mounting surface of the storage battery is pressed by a holding metal to prevent the battery from jumping out and falling.

However, on the terminal mounting surface of the storage battery,
Functional components such as safety valves are arranged in addition to the terminals.Therefore, the flat surface area is narrow and it is difficult to hold the storage battery with sufficient strength without interfering with the functional components. Contacting the terminals may cause a short circuit, which may cause danger in construction.

The present invention has been made in view of such a point. It is an object of the present invention to easily and efficiently perform maintenance and inspection work on a storage battery, and to perform an earthquake without using a holding bracket. It is an object of the present invention to provide a storage battery mount that can reliably prevent the storage battery from jumping out and dropping due to the above.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a storage battery mount provided with a receiving member for supporting a plurality of storage batteries in an inclined state. However, the receiving member is provided at a small inclination angle such that 26.6 ° ≦ inclination angle α <0 °.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of the storage battery mount, and FIG. 2 is a front view of the same. The gantry 1 has a pair of side frames 2 and 3 spaced apart from each other left and right, and angle members 4 and 5 are attached to the inside of each side frame 2 and 3 in a plurality of steps.

A flat receiving member 6 is provided in a shelf shape between the angle members 4 of each step of the one side frame 2 and the angle members 5 of each step of the other side frame 3. Each receiving member 6 is inclined obliquely upward toward the front front side of the gantry 1,
The inclination angle is an angle of α with respect to the vertical.

A supporting member 7 is mounted on the upper surface on the depth side of each receiving member 6 at right angles to the upper surface thereof, and the receiving member 6 and the supporting member 7 constitute a battery housing portion 8. A plurality of storage batteries 9 are stored in each of the battery storage sections 8 in each stage in parallel on the left and right. Each storage battery 9
Is accommodated in the battery accommodating portion 8 from the front of the gantry 1 so that the terminal mounting surface having the terminal 10 and the safety valve 11 is arranged on the front of the gantry 1, and is supported by the receiving member 6 and the support member 7. Note that a cushioning member 12 made of an elastic member such as a rubber sheet is attached to the upper surface of each of the receiving members 6 and the supporting members 7.

FIG. 3 shows the structure of the supporting portion of the storage battery 9 in an enlarged manner. CG shown in the figure is the position of the center of gravity of the storage battery 9, and the position of the center of gravity CG is lower than the position of the upper edge of the receiving member 6.

Here, the relationship between the static horizontal acceleration applied to the storage battery 9 is KH [G], the static vertical acceleration is KV [G], and the force acting on the storage battery 9 when the gravitational acceleration G = 1 is obtained. It becomes as follows.

Since the static vertical acceleration KV acts upward and the direction of the force is opposite to the gravitational acceleration G, the resultant force is 1-KV. Therefore, the resultant force of this force and the static horizontal acceleration becomes the resultant force of all the elements, and is obtained by the following equation.

Tan θ = (1−KV) / KH The angle θ at which the force acts is as follows: θ = tan ⁻¹ {(1−KV) / KH}. Here, as a condition required for an earthquake-resistant structure, K
Since V = (1/2) KH, if the required horizontal acceleration is KH = 1G, KV = 0.5G, and θ = tan ^-1 ｛(1−KV) / KH｝ = tan ⁻¹ ( 1/2) = about 26.6 °.

That is, the angle at which the force acts on the storage battery 9 is about 26.6 ° downward with respect to the horizontal. That is, if the receiving member 6 is inclined so as to be perpendicular to the direction of the angle θ, the resultant force of all elements of the storage battery 9 does not become a force for moving the storage battery 9, and the storage battery 9 It only acts as a pressing force.

When the inclination angle α of the receiving member 6 that satisfies this condition with respect to the erect state of the storage battery is obtained, α = 180 ° −90 ° − (90 ° −θ) Therefore, α = θ = about 26.6 ° If α is within this angle, the storage battery 9 arranged on the receiving member 6 will not move upward along the receiving member 6 even if it receives a horizontal force.

Therefore, when the earthquake occurs, the storage battery 9
Can be reliably prevented from jumping out or falling off without using any holding metal. For this reason, the storage battery 9
The installation work can be easily and efficiently carried out and installed, and a holding fixture is not required, so that there is no danger of construction such as a short-circuit of the terminal 10.

On the other hand, a portion indicated by A in FIG. 1 is an area for construction and inspection workers in front of the gantry 1, and a portion indicated by B is a space for maintenance and inspection on the upper surface side of each storage battery 9. here,
If the inclination angle α is within 26.6 °, the construction inspection worker area A and the maintenance inspection space B of the storage battery 9 do not interfere with each other. Maintenance work can be easily and efficiently performed. In other words, the maintenance and inspection site of the storage battery 9 is in a position where the worker naturally faces upward (the position where the worker naturally faces downward and the arm is lowered), which facilitates the work.

However, when the inclination α becomes 0 °, the battery 9
Is set upright and in a vertically installed state, and it is necessary to secure a large space for maintenance and inspection above the terminal portion of the storage battery 9 in each stage. Therefore, the inclination angle α is set to less than 0 °.

Therefore, in the present invention, the condition of 26.6 ° <inclination angle α <0 ° is satisfied.

[0023]

As described above, according to the present invention,
The maintenance and inspection work for the storage battery can be easily and efficiently performed, and the storage battery can be reliably prevented from jumping out and dropping due to an earthquake or the like without using a holding fixture.
