【考案の詳細な説明】
この考案は、タンクローりの配管構造の改良に係るもの
である。[Detailed description of the invention] This invention relates to an improvement of the piping structure of a tank truck.
一般に、石油類を運搬するタンクローりのシャシフレー
ム上面は、積荷（以下油という）を積んだ状態ではほぼ
水平となり、おろしたときには若干前側が低い状態とな
るように設計されている。Generally, the upper surface of the chassis frame of a tank truck that transports petroleum is designed so that when loaded with cargo (hereinafter referred to as oil), the top surface of the chassis frame is almost horizontal, and when unloaded, the front side is slightly lower.
これはタンクローりの油積載時の走行性及び安全性等を
考慮したものである。This is done in consideration of the running performance and safety of the tank truck when it is loaded with oil.
一方、荷おろしするガソリンスタンド等の路面は必ずし
も水平でなく若干傾斜している場合が多い。On the other hand, the road surface at gas stations, etc. where cargo is unloaded is not necessarily level, but is often slightly sloped.
したがって、これら変化する路面及び車両姿勢によって
油の荷おろし時に油の一部がタンク及び配管内に残存す
るという問題がある。Therefore, due to these changing road surfaces and vehicle postures, there is a problem that some oil remains in the tank and piping when the oil is unloaded.
勿論、ポンプ等によって強制的に荷おろしすればこのよ
うな問題はないが、油等の危険物をガソリンスタンドの
地下貯蔵タンクに荷おろしする場合には安全性も考慮し
てポンプを使用しないのが規則であるため、前記問題を
解決するには至らない。Of course, this problem does not arise if the cargo is forcibly unloaded using a pump, etc., but when unloading hazardous materials such as oil into underground storage tanks at gas stations, it is recommended not to use pumps for safety reasons. is the rule, so it does not solve the above problem.
この考案は、上記問題を解決することを企図してなされ
たもので、路面及び車両姿勢にかかわらずタンク内及び
配管内の油を残らず迅速に荷おろしできるようにしたこ
とを特徴とするタンクローリの配管構造を提供しようと
するものである。This invention was made with the intention of solving the above problem, and it is a tank lorry that is characterized by being able to quickly unload cargo without leaving any oil in the tank or pipes, regardless of the road surface or vehicle posture. The aim is to provide a piping structure for this purpose.
以下にこの考案の実施例を図面に基づいて説明する。Examples of this invention will be described below based on the drawings.
第１図はこの考案の配管構造を有するタンクローりの側
面図で、シャシフレーム１上に搭載されるタンク２内は
仕切壁（図示せず）をもって複数の室に区画されており
、各室の底部に配設される各底弁３を連結する主配管４
と、車両長手方向に沿うこの主配管４のほぼ中間に切換
弁５を介して連結されかつ車両の左右方向に延びる補助
配管６とから成る配管系統がタンク２の下部のシャシフ
レーム１の上部のサブフレーム１′の内部に配列されて
いる。Figure 1 is a side view of a tank truck having the piping structure of this invention. The inside of a tank 2 mounted on a chassis frame 1 is divided into a plurality of chambers by partition walls (not shown), and each chamber is separated by a partition wall (not shown). Main pipe 4 connecting each bottom valve 3 arranged at the bottom
A piping system consisting of an auxiliary piping 6 connected to approximately the middle of this main piping 4 along the longitudinal direction of the vehicle via a switching valve 5 and extending in the left-right direction of the vehicle is connected to the upper part of the chassis frame 1 at the bottom of the tank 2. They are arranged inside the subframe 1'.
この場合、タンク２の各室内の油は、底弁３を通って主
配管４内に導かれ、そして、切換弁５を通って補助配管
６に導かれた後、補助配管６の両端部に配設された吐出
弁７の吐出操作により左又は右の吐出口６ａ又は６ｂか
ら図示しない所定の貯蔵タンク内に荷おろしされるので
ある。In this case, the oil in each chamber of the tank 2 is led into the main pipe 4 through the bottom valve 3, and then into the auxiliary pipe 6 through the switching valve 5, and then into both ends of the auxiliary pipe 6. By discharging the discharge valve 7 provided therein, the cargo is unloaded from the left or right discharge port 6a or 6b into a predetermined storage tank (not shown).
この際、配管内の油を残り無く吐出するためには底弁３
から吐出口６ａ、６ｂ迄全てにわたり、多少の路面の傾
斜及びシャシフレーム１の傾斜を吸収しかつ若干この傾
斜を上回る傾斜を付ければ良いことになる。At this time, in order to discharge all the oil in the pipe, the bottom valve 3
All that is required is to absorb the slope of the road surface and the slope of the chassis frame 1 to some extent and to provide a slope that slightly exceeds the slope from the exhaust ports 6a and 6b to the discharge ports 6a and 6b.
しかし、このような構造にするには主配管４と補助配管
６とが交差した状態で主配管４に傾斜を付けなければな
らないためサブフレーム１′の高さＨを高くしなければ
ならず、そのため車体が全体的に高くなるという不都合
が生じる結果となる。However, to create such a structure, the main pipe 4 must be inclined with the main pipe 4 intersecting with the auxiliary pipe 6, so the height H of the subframe 1' must be increased. This results in the inconvenience that the overall height of the vehicle body increases.
そこで、この考案は上記問題を解決することを企図して
なされたもので、第２図及び第３図に示すように、主配
管４の前端部分ａから補助配管６の上部に至る部分すを
補助配管６と接触しない範囲で下り勾配に形威し、この
部分すから後方に位置する切換弁接続部分Ｃまでを下方
に向けて急勾配にするとともに、主配管４の後端部分ｄ
から切換弁接続部分Ｃに向って下り勾配に形威し、そし
て、前記主配管４の前端部分ａの近傍部分と補助配管６
の一側の下部とを抜き取り管８で連結する。Therefore, this invention was made with the intention of solving the above problem, and as shown in FIGS. It forms a downward slope within a range that does not contact the auxiliary pipe 6, and has a steep slope downward from this part to the switching valve connection part C located at the rear, and the rear end part d of the main pipe 4.
It forms a downward slope toward the switching valve connecting portion C, and connects the vicinity of the front end portion a of the main pipe 4 and the auxiliary pipe 6.
and the lower part of one side thereof are connected by a extraction pipe 8.
この抜き取り管８には前記切換弁５に接続されたポンプ
（図示せず）と接続する抜き取り用切換弁９が配設され
ている。This extraction pipe 8 is provided with a extraction switching valve 9 connected to a pump (not shown) connected to the switching valve 5.
上記のように構成されるこの考案の配管構造から荷おろ
しを行なう場合、補助配管６より後方部分にある底弁か
らの排出は、補助配管の位置に制約されず主配管４の傾
斜が大きくとれているので、配管１４に油の残留がなく
行なわれる。When unloading from the piping structure of this invention constructed as described above, the discharge from the bottom valve located at the rear of the auxiliary piping 6 is not restricted by the position of the auxiliary piping, and the main piping 4 can be tilted to a large extent. Therefore, there is no oil remaining in the piping 14.
しかし、補助配管６より前方にある底弁からの排出時、
路面の状態等により、車体が前に傾くと、主配管４の前
端部分ａと補助配管上方部分すとがほぼ水平に近い状態
となるので、路面及び車両の傾斜が累積された状態にお
いてはｂがａより高くなり、主配管４のａ、 ｂ間に油
が残るが、前記路面及び車両の傾斜の累積分を吸収し得
るように傾斜上に配管された抜き取り管８を介して残っ
た油は補助配管６へ導かれ、所定の貯蔵タンクへ荷おろ
しすることができる。However, when discharging from the bottom valve located in front of the auxiliary pipe 6,
When the vehicle body leans forward due to the condition of the road surface, etc., the front end part a of the main pipe 4 and the upper part of the auxiliary pipe become almost horizontal, so when the slope of the road surface and the vehicle is accumulated, b becomes higher than a, and oil remains between a and b of the main pipe 4, but the remaining oil is removed through a withdrawal pipe 8 installed on the slope so as to absorb the accumulated amount of slope of the road surface and vehicle. is led to the auxiliary pipe 6 and can be unloaded into a predetermined storage tank.
この状態すなわち重力で荷おろしする時開放する抜き取
り用切換弁９は、タンク２内の油の排出又はタンク２内
へ油を吸い上げる時は閉止されるようになっている。In this state, the extraction switching valve 9, which is opened when unloading by gravity, is closed when draining the oil from the tank 2 or sucking up oil into the tank 2.
以上に説明したように、この考案の配管構造によれば、
路面及び車両姿勢にかかわらずタンク内及び配管内の油
を残らず迅速に荷おろしすることができるので、配送効
率の向上を図ることができ、また、貴重なエネルギ源で
ある油の有効利用を図れるなどの優れた効果が得られ、
その利用価値は顕著である。As explained above, according to the piping structure of this invention,
Regardless of the road surface or vehicle posture, it is possible to unload the cargo quickly without leaving any oil in the tank or pipes, thereby improving delivery efficiency and making effective use of oil, which is a valuable energy source. You can get excellent effects such as being able to
Its utility value is remarkable.
