Description

  The present invention relates to a tank structure.

  Conventionally, as a tank structure, there is a tank structure in which a pump and a motor are fixed to a top plate of a tank as disclosed in JP-A-6-42501 (Patent Document 1).

Japanese Patent Laid-Open No. 6-42501

  By the way, in the conventional tank structure, since the pump and the motor are fixed to the top plate of the tank, it is necessary to make the top plate of the tank thick. As a result, the manufacturing cost of the tank is high.

  As a method of thinning the top plate of the tank, a method of mounting a tank, a pump, and a motor on a base separate from the tank can be considered.

  However, when a tank, a pump, and a motor are mounted on the base, a small base is used for a small capacity tank, while a large base is used for a large capacity tank.

  Therefore, since the base can be used only for a tank having a capacity corresponding to the size of the base, the versatility is lowered, resulting in an increase in manufacturing cost.

  Then, the subject of this invention is providing the tank structure which can reduce manufacturing cost.

In order to solve the above problems, the tank structure of the present invention is
Basic base,
Is detachably mounted on the main base, and a tank for storing oil,
The basic base has a support surface for supporting all of the tank, Ri connectable der directly or indirectly so as to be arranged in the horizontal direction to the extension base,
The extension base is connected directly or indirectly to the basic base in a horizontal direction, a part of the tank is disposed on the basic base, and the other part of the tank is disposed on the extension base. When the portion is arranged, a part of the tank is supported by the support surface of the basic base, the support surface of the basic base is extended by the extension base, and other parts of the tank some are characterized by Rukoto such so as to be supported.

  According to the above configuration, the basic base can be directly or indirectly connected to the extension base so as to be aligned in the horizontal direction. Thus, if the extension base is connected directly or indirectly to the basic base so as to be arranged in the horizontal direction, the tank can be mounted on the basic base and the extension base even if the capacity of the tank is large.

  Further, when the capacity of the tank is small, the tank can be mounted only on the basic base.

  Thus, the basic base can be used for large-capacity and small-capacity tanks, and is therefore highly versatile. Therefore, the tank structure can reduce the manufacturing cost.

  Further, since the tank is detachably mounted on the basic base, the tank can be separated from the basic base. Thereby, the basic base and the tank can be individually dip-painted (so-called soaking). Therefore, the dip coating of the basic base and the tank is simplified.

  Further, since the tank is detachably mounted on the basic base, the basic base and the tank can be transported by separating the tank from the basic base. Therefore, when the basic base and the tank are transported, the place for placing the basic base and the tank can be reduced. As a result, the transport efficiency of the basic base and the tank can be improved.

In the tank structure of the present invention ,
Basic base,

The basic base has a support surface for supporting a part of the tank,
A portion of the tank is disposed on the base base, and another portion of the tank is disposed on the extension base, and the support surface of the base base is extended by the extension base, and that are characterized by another part of the tank is supported.

According to the above configuration, more extended base that is connected directly or indirectly to be aligned in a horizontal direction at the main base, even if the capacity of the tank is large, be mounted a tank main base and extension base it can.

In the tank structure of one embodiment,
The basic base is mounted with a pump so as to be arranged in a horizontal direction in the tank.

  According to the above embodiment, the motor and the pump are mounted on the basic base so as to be aligned in the horizontal direction in the tank. Thereby, the thickness of the tank can be reduced and the manufacturing cost of the tank can be reduced.

  Further, since the noise of the motor and the pump can be blocked by the tank, the noise can be reduced.

  The tank structure of the present invention includes a basic base and a tank that is detachably mounted on the basic base, and the basic base can be directly or indirectly connected to the extension base so as to be aligned horizontally. Since the tank can be used with a large capacity or a small capacity, it is highly versatile. Therefore, the tank structure can reduce the manufacturing cost.

  Further, since the tank is detachably mounted on the basic base, the basic base and the tank can be individually dip-coated. Therefore, the tank structure can simplify the dip coating of the basic base and the tank.

  Further, since the tank is detachably mounted on the basic base, the tank can be separated from the basic base, and the transport efficiency of the basic base and the tank can be improved.

Thereby, the rear leg portion 102 of the basic base 1 is directly connected to the front leg portion 302 of the extension base 3 in a detachable manner.

  According to the tank structure configured as described above, the basic base 1 can be directly connected to the extension base 3 so as to be aligned in the front-rear direction. As a result, if the extension base 3 is connected directly or indirectly to the basic base 1 in the front-rear direction, the tank 2 has a large capacity of 60 L, but the tank 2 can be mounted on the basic base 1 and the extension base 3. it can.

  Further, when using a tank (not shown) having a small capacity of, for example, 30 L, the tank can be mounted only on the basic base 1. That is, it is not necessary to use the extension base 3.

  As described above, the basic base 1 can be used for the large-capacity and small-capacity tanks 2, and therefore has high versatility. Therefore, the tank structure can reduce the manufacturing cost.

  Further, since the tank 2 is detachably mounted on the basic base 1, it can be separated from the basic base 1. Therefore, since the tank 2 and the basic base 1 can be individually dip-coated, the dip coating is simplified.

  Further, since the tank 2 is detachably mounted on the basic base 1, the basic base 1 and the tank 2 can be transported by separating the tank 2 from the basic base 1. Therefore, when the basic base 1 and the tank 2 are transported, the place where the basic base 1 and the tank 2 are placed can be reduced, so that the transport efficiency of the basic base 1 and the tank 2 can be improved.

  In addition, a motor 4 and a pump 5 are mounted on the basic base 1 so as to be aligned with the tank 2 in the front-rear direction. Thereby, the thickness of the tank upper plate 202 can be reduced to, for example, 2.3 mm, and the manufacturing cost of the tank 2 can be reduced.

  Moreover, since the noise of the motor 4 and the pump 5 can be blocked by the tank 2, the noise can be reduced.

  In the said embodiment, the cover which covers the motor 4 and the pump 5 may be attached to the basic base 1 so that noise can be further reduced.

  In the above embodiment, the extension base 3 is directly connected to the basic base 1 so as to be aligned in the horizontal direction, but may be indirectly connected to the basic base 1 so as to be aligned in the horizontal direction. For example, a plate material may be interposed between the basic base 1 and the extension base 3.

  In the above embodiment, the extension base 3 is detachably connected directly to the basic base 1 so as to be arranged in the front-rear direction. However, the extension base 3 is directly connected to the basic base 1 so as to be non-detachable so as to be arranged in the front-rear direction. May be.

  In the above embodiment, the tank 2 is partially located on the basic base 1, but may be entirely located on the basic base 1. In this case, the extension base 3 does not have to be directly or indirectly connected to the basic base 1 so as to be aligned in the horizontal direction.

Bolts 1251 are inserted into and tightened through the through holes 1213a and the through holes 1102a of the legs 1102 on the rear side of the basic base 1001. As a result, the front leg 1213 of the tank body 1201 is detachably connected directly to the rear leg 1102 of the basic base 1001.

  According to the tank structure having the above configuration, even if a tank (not shown) having a capacity larger than that of the tank 1002 is used, the basic base 1001 can be used, so that versatility is high. Therefore, the tank structure can reduce the manufacturing cost.

  Further, the tank 1002 can be separated from the basic base 1001 by loosening the bolt 1251. Accordingly, since the basic base 1001 and the tank 1002 can be individually dip-coated, the dip coating is simplified.

  Further, by loosening the bolt 1251, the tank 1002 can be separated from the basic base 1001, and the basic base 1001 and the tank 1002 can be transported. Therefore, when the basic base 1001 and the tank 1002 are transported, the place for placing the basic base 1001 and the tank 1002 can be reduced, so that the transport efficiency of the basic base 1001 and the tank 1002 can be improved.

  The basic base 1001 is equipped with a motor and a pump. Thereby, the thickness of the tank upper plate 1202 can be reduced to, for example, 2.3 mm, and the manufacturing cost of the tank 1002 can be reduced.

Bolts 2251 are inserted into and tightened into the through holes 2213a and the through holes 2102b in the rear legs 2102 of the basic base 2001. Thereby, the front leg portion 2213 of the tank body 2201 is detachably connected directly to the rear leg portion 2102 of the basic base 2001.

  Further, leg portions 2216 are provided on the peripheral edge portion of the lower surface of the tank body 2201 so as to be positioned between the rear leg portions 2213. The length of the leg portion 2216 in the left-right direction is longer than the length of the leg portion 2213 in the left-right direction.

  According to the tank structure having the above configuration, the basic base 2001 can be used even when a tank (not shown) having a capacity larger than that of the tank 2002 is used. Therefore, the tank structure can reduce the manufacturing cost.

  Further, the tank 2002 can be separated from the basic base 2001 by loosening the bolt 2251. Accordingly, since the base base 2001 and the tank 2002 can be individually dip-coated, the dip coating is simplified.

  Further, by loosening the bolt 2251, the tank 2002 can be separated from the basic base 2001, and the basic base 2001 and the tank 2002 can be transported. Therefore, when the basic base 2001 and the tank 2002 are transported, the place where the basic base 2001 and the tank 2002 are placed can be reduced, so that the transport efficiency of the basic base 2001 and the tank 2002 can be improved.
