Description

本発明は、油圧ショベル等の建設機械の燃料給油器具に関する。   The present invention relates to a fuel supply device for a construction machine such as a hydraulic excavator.

一般に小旋回の油圧ショベルは、旋回時に障害となる突起物を極力少なくする構造をとっている。これは周囲への安全性と油圧ショベル自体の損傷の防止のためである。また、油圧ショベルのボディには燃料給油口が設けられている。この燃料給油口は安全面からも重要であり、保護を目的として車体外側面より突出させない構造をとっている。例えば、特開２００３−２１１９８３号公報に記載の油圧ショベルでは、本体カバーに凹状のシール部材を装着し、このシール部材の凹状空間内に給油口金が収まるように燃料給油口を設けている。   Generally, a small-turning hydraulic excavator has a structure that minimizes protrusions that become obstacles during turning. This is for safety to the surroundings and prevention of damage to the excavator itself. The body of the hydraulic excavator is provided with a fuel filler port. The fuel filler port is important from the viewpoint of safety, and has a structure that does not protrude from the outer surface of the vehicle body for the purpose of protection. For example, in a hydraulic excavator described in Japanese Patent Application Laid-Open No. 2003-211983, a concave seal member is attached to a main body cover, and a fuel filler port is provided so that a fuel filler cap fits in a concave space of the seal member.

しかしながら、上記従来技術には次のような問題がある。   However, the above prior art has the following problems.

油圧ショベル等の建設機械の場合、燃料給油口から給油する方法としては、注ぎ口を装着した燃料容器を用い、注ぎ口を燃料給油口の給油開口部に挿入し、燃料容器を傾けて燃料を注ぐのが一般的である。しかし、海外においては、燃料容器は多種であり、燃料容器に注ぎ口が付いていないものも多い。このような燃料容器から給油を行う場合、油圧ショベルの燃料給油口が本体カバーの外側面から奥に位置するため、給油作業がやり難い問題があった。その改善策として、顧客側で給油器具が個々に工夫がなされてているものの、給油器具の手持ちによる作業のやり難さ、燃料にゴミ混入発生等の問題があった。また、金属製の給油器具による場合は、給油器具に燃料容器を載せかけた場合に油圧ショベル側の燃料給油口と干渉し、燃料給油口が破損する問題もあった。   In the case of a construction machine such as a hydraulic excavator, as a method of refueling from a fuel refueling port, use a fuel container equipped with a spout, insert the spout into the fuel refueling opening of the fuel refueling port, tilt the fuel container, It is common to pour. However, overseas, there are many kinds of fuel containers, and many of them do not have spouts. When refueling from such a fuel container, the fuel refueling port of the excavator is located at the back from the outer surface of the main body cover. As measures to improve this, there have been problems such as difficulty in carrying out the work by hand of the refueling device and occurrence of dust in the fuel, although the refueling device has been devised individually by the customer side. Further, in the case of using a metal fueling device, there is a problem that when the fuel container is placed on the fueling device, it interferes with the fuel oil supply port on the excavator side and the fuel oil supply port is damaged.

The strainer 210 has a straight-shaped inlet tube portion 210a and a taper-shaped mesh portion 210b. A flange portion 210c is formed at the upper end of the inlet tube portion 210a of the strainer 210, and this flange portion is used as the oil filler base 202. The strainer 210 is supported in the fuel filler base 202 by being engaged with a support ring 202 a provided on the inner peripheral portion of the oil filler base 202.

図６に燃料給油口２００に燃料給油器具１を差し込んだ状態を斜視図で示し、図７に同じ状態を断面図で示す。以下図７を用い、燃料給油器具１の構成をより詳細に説明する。   FIG. 6 is a perspective view showing a state in which the fuel filler 1 is inserted into the fuel filler opening 200, and FIG. 7 is a sectional view showing the same state. Hereinafter, the configuration of the fuel supply device 1 will be described in more detail with reference to FIG.

燃料給油器具１の第１挿入部分３の外径部は、ストレーナー２１０の入口筒部２１０ａのストレート形状に合わせたストレート形状としており、脱着を容易にするため、その外径をストレーナー２１０の入口筒部２１０ａの内径より若干（例えば１ｍｍ程度）小径としてストレーナー２１０の入口筒部２１０ａとの間に隙間を持たせている。第１挿入部分３は、挿入が容易に行えるように案内となる長さを持たせている。   The outer diameter portion of the first insertion portion 3 of the fuel refueling device 1 has a straight shape that matches the straight shape of the inlet tube portion 210a of the strainer 210, and the outer diameter thereof is set to the inlet tube of the strainer 210 for easy attachment / detachment. The inner diameter of the portion 210a is slightly smaller (for example, about 1 mm) than the inner diameter of the portion 210a so that a gap is provided between the inlet cylinder portion 210a of the strainer 210. The first insertion portion 3 has a guide length so that the insertion can be easily performed.

また、第１挿入部分３は、外径部のストレート形状と相俟って、燃料給油器具１の装着状態を安定させる長さを有している。燃料給油器具１は、燃料給油口２００に差し込んだ状態では、第２挿入部分４が嵌合する開口部２０３と第１挿入部分３が挿入されるストレーナー２１０の入口筒部２１０ａとの２箇所で支持され、第１挿入部分３と第２挿入部分４のその２箇所の距離が支持スパンとなる。この場合、燃料給油器具１は上記のように第１及び第２挿入部分３，４も含め柔軟性のあるラバーで一体に構成されているため、第１挿入部分３と第２挿入部分４の支持スパンが短いと燃料給油器具１の装着が不安定となる。第１挿入部分３の外径部をストレート形状とすることでその全長がストレーナー２１０の入口筒部２１０ａに支持されるため、第２挿入部分４の開口部２０３との接触部から第１挿入部分３の先端部までが支持スパンとなる。これにより第１挿入部分３の長さを適切化することで適切な長さの支持スパンが得られ、装着状態を安定させることができる。また、このようにストレーナー２１０入口筒部２１０ａの奥部まで挿入させることで流れ込む燃料をストレーナー網部２１０ｂまで導かせ、ゴミ類を完全に取り去ることができる。   Moreover, the 1st insertion part 3 has the length which stabilizes the mounting state of the fuel supply instrument 1 combined with the straight shape of an outer diameter part. In a state where the fuel filler 1 is inserted into the fuel filler port 200, the fuel filler 1 is provided at two locations, that is, an opening 203 into which the second insertion portion 4 is fitted and an inlet tube portion 210a of the strainer 210 into which the first insertion portion 3 is inserted. The distance between the two positions of the first insertion portion 3 and the second insertion portion 4 is a support span. In this case, since the fuel refueling device 1 is integrally formed of flexible rubber including the first and second insertion portions 3 and 4 as described above, the first insertion portion 3 and the second insertion portion 4 If the support span is short, the mounting of the fuel supply device 1 becomes unstable. By making the outer diameter portion of the first insertion portion 3 straight, the entire length thereof is supported by the inlet tube portion 210a of the strainer 210, so that the first insertion portion is contacted with the opening portion 203 of the second insertion portion 4. Up to the tip of 3 is a support span. Thereby, by optimizing the length of the first insertion portion 3, a support span having an appropriate length can be obtained, and the mounting state can be stabilized. Further, the fuel flowing in can be guided to the strainer net 210b by being inserted as far as the inner side of the strainer 210 inlet tube 210a, and the garbage can be completely removed.

第２挿入部分４の外径部はテーパー形状をしている。このため第２挿入部分４を開口部２０３に押し込むことで第２挿入部分４のラバーが変形して開口部２０３に食い込み、第２挿入部分４は開口部２０３に確実に嵌合する。その結果、燃料給油器具１の装着状態が安定し、特に、燃料給油時に燃料給油器具１が第１挿入部分３、第２挿入部分４、燃料注ぎ口部分２を通る長手方向の中心軸線Ａ回りに回転することが防止される。燃料給油時に発生する空気の逃がしは、燃料給油口２００の２箇所の掛かり溝２０６，２０６から排出され、空気の逆戻りによる燃料吹出しは無い。   The outer diameter portion of the second insertion portion 4 has a tapered shape. Therefore, when the second insertion portion 4 is pushed into the opening 203, the rubber of the second insertion portion 4 is deformed and bites into the opening 203, and the second insertion portion 4 is securely fitted into the opening 203. As a result, the mounting state of the fuel supply device 1 is stabilized, and in particular, around the longitudinal central axis A through which the fuel supply device 1 passes through the first insertion portion 3, the second insertion portion 4, and the fuel spout portion 2 during fuel supply. Is prevented from rotating. The escape of air generated when fuel is supplied is discharged from the two hooking grooves 206 and 206 of the fuel supply port 200, and there is no fuel blowing out due to the backflow of air.

燃料注ぎ口部分２のラッパ形状は、最上端位置まで燃料を注がれたときの燃料給油器具１内の燃料の重心位置が第１挿入部分３、第２挿入分、燃料注ぎ口部分２の中心軸線Ａより下方に位置するような形状となっており、これにより燃料給油器具１内に燃料が注がれたときの燃料の自重による中心軸線Ａ回りの回転力を最小とし、上記第２挿入部分４の開口部２０３への嵌合と相俟って燃料給油器具１の回転ずれが確実に防止され、燃料がこぼれることは無い。燃料注ぎ口部分２の最上端開口部の周囲には、燃料給油器具１を燃料給油口２００に装着したときに建設機械の本体カバー１０９に向く側を直線部６ａとしたフランジ状の安定板６が設けられている。   The trumpet shape of the fuel spout portion 2 is such that the position of the center of gravity of the fuel in the fuel supply device 1 when the fuel is poured to the uppermost end position is that of the first insertion portion 3, the second insertion portion, and the fuel spout portion 2. The shape is such that it is positioned below the central axis A, thereby minimizing the rotational force around the central axis A due to the weight of the fuel when the fuel is poured into the fuel supply device 1. Coupled with the fitting of the insertion portion 4 into the opening 203, the rotational deviation of the fuel supply device 1 is reliably prevented, and no fuel spills. Around the uppermost opening of the fuel spout portion 2, a flange-shaped stabilizer 6 having a straight portion 6 a on the side facing the main body cover 109 of the construction machine when the fuel filler 1 is attached to the fuel filler 200. Is provided.

本実施の形態に係わる燃料給油器具１を使用するには、まず、燃料給油口２００からキャップ２０４を取り外し、燃料給油器具１の第１挿入部分３及び第２挿入部分４を燃料給油口２００に差し込んで、第１挿入部分３をストレーナー２１０の入口筒部２１０ａに挿入し、第２挿入部分４を開口部２０３に嵌合させる。これにより燃料給油器具１は燃料給油口２００に取り付けられ、作業者は両手を使える状態となる。次いで、作業者はその両手を使って燃料容器を燃料給油器具１の燃料注ぎ口部分２の上方に持ち上げ、燃料容器を傾けることで燃料が燃料注ぎ口部分２に注がれ、その燃料は第２挿入部分４、第１挿入部分３からストレーナー２１０に流入し、ここでゴミ類が取り去られた後、給油管２０１を介して燃料タンクへと流れ込む。   In order to use the fuel supply device 1 according to the present embodiment, first, the cap 204 is removed from the fuel supply port 200, and the first insertion portion 3 and the second insertion portion 4 of the fuel supply device 1 are connected to the fuel supply port 200. The first insertion portion 3 is inserted into the inlet tube portion 210 a of the strainer 210, and the second insertion portion 4 is fitted into the opening 203. Thereby, the fuel supply device 1 is attached to the fuel supply port 200, and the operator can use both hands. Next, the operator lifts the fuel container with the use of both hands above the fuel spout portion 2 of the fuel refueling device 1 and tilts the fuel container so that the fuel is poured into the fuel spout portion 2. 2 It flows into the strainer 210 from the insertion part 4 and the first insertion part 3, and after the garbage is removed here, it flows into the fuel tank through the fuel supply pipe 201.

図８は、異なる機種の燃料給油口に本実施の形態の燃料給油器具を装着した状態を、図７と同様な断面図で示す図である。   FIG. 8 is a cross-sectional view similar to FIG. 7, showing a state in which the fuel refueling device of the present embodiment is attached to a fuel refueling port of a different model.

燃料給油器具１を異なる機種に用いる場合は、燃料給油器具１の第１及び第２挿入部分３，４を燃料給油口２００に差し込めない場合もある。この場合は、補助具として、下方部分に複数の横穴８ａの開いた挿入パイプ８を用いて次のように燃料給油器具１を燃料給油口２００に取り付ける。つまり、挿入パイプ８を燃料給油器具１の第１挿入部分３の穴部分に挿入して装着し、挿入パイプ８を給油口金２０２の開口部２０３からストレーナー２１０内に挿入する。このとき、安定板６の直線部６ａを本体カバー１０９に接触させ、回転方向に安定させる。   When the fuel filler 1 is used for different models, the first and second insertion portions 3 and 4 of the fuel filler 1 may not be inserted into the fuel filler opening 200 in some cases. In this case, the fuel supply device 1 is attached to the fuel supply port 200 as follows using an insertion pipe 8 having a plurality of lateral holes 8a in the lower portion as an auxiliary tool. That is, the insertion pipe 8 is inserted and attached to the hole portion of the first insertion portion 3 of the fuel supply device 1, and the insertion pipe 8 is inserted into the strainer 210 from the opening 203 of the fuel filler base 202. At this time, the linear portion 6a of the stabilizing plate 6 is brought into contact with the main body cover 109 to stabilize in the rotational direction.

以上のように構成した本実施の形態によれば、次の効果が得られる。   According to the present embodiment configured as described above, the following effects can be obtained.

１）燃料給油器具１にストレーナー２１０に挿入される第１挿入部分３と、燃料給油口２００の入口部分の開口部２０３に挿入される第２挿入部分４とを備える構成としたので、燃料給油器具１を燃料給油口２００に直接取付可能となり、燃料容器に注ぎ口が付いていない場合でも、作業者は両手を使って効率良く、安全に給油することができる。   1) The fuel refueling device 1 includes the first insertion portion 3 that is inserted into the strainer 210 and the second insertion portion 4 that is inserted into the opening 203 of the inlet portion of the fuel refueling port 200. The tool 1 can be directly attached to the fuel filler 200, and even if the fuel container does not have a spout, the operator can efficiently and safely refuel using both hands.

２）燃料給油口２００の入口部分の開口部２０３に挿入される第２挿入部分４を設けたので、流れ込む燃料をストレーナー２１０網部まで導かせてゴミ類を取り去ることができ、燃料タンク内にゴミ類が流入することが防止できる。   2) Since the second insertion portion 4 to be inserted into the opening 203 of the inlet portion of the fuel filler port 200 is provided, it is possible to guide the flowing fuel to the net portion of the strainer 210 and remove the garbage, The inflow of garbage can be prevented.

３）燃料給油器具１の全体を構成する材質に柔軟性のあるラバーを使用したので、燃料給油時に燃料容器を燃料給油器具１に乗せたり、ぶつけたりしても、そのラバーが変形するので、燃料給油口２００を損傷させることは無い。   3) Since a flexible rubber is used as the material constituting the entire fuel refueling device 1, even if the fuel container is placed on or hit against the fuel refueling device 1 during fuel refueling, the rubber will be deformed. The fuel filler opening 200 is not damaged.

４）第１挿入部分３の外径部をストレート形状とし、その外径をストレーナー２１０の入口筒部２１０ａの内径より小径としてストレーナー２１０の入口筒部２１０ａとの間に隙間を持たせたので、燃料給油器具１の脱着が容易に行える。   4) Since the outer diameter portion of the first insertion portion 3 has a straight shape, the outer diameter is smaller than the inner diameter of the inlet tube portion 210a of the strainer 210, and a gap is provided between the inlet tube portion 210a of the strainer 210. The fuel supply device 1 can be easily attached and detached.

５）第１挿入部分３の外径部をストレート形状としたので、第１挿入部分３と第２挿入部分４との間に適切な長さの支持スパンが得られ、装着状態を安定させることができる。特に、燃料給油器具１の全体を構成する材質に柔軟性のあるラバーを使用した場合は、燃料給油器具１の装着は不安定となるが、その場合でも装着状態を安定させることができる。   5) Since the outer diameter portion of the first insertion portion 3 has a straight shape, a support span having an appropriate length is obtained between the first insertion portion 3 and the second insertion portion 4, and the mounting state is stabilized. Can do. In particular, when a flexible rubber is used as the material constituting the entire fuel supply device 1, the fuel supply device 1 is unstable in mounting, but even in that case, the mounting state can be stabilized.

６）第２挿入部分４の外径部をテーパー形状としたので、第２挿入部分４を開口部２０３に押し込むことで、第２挿入部分４のラバーが開口部２０３に食い込んで第２挿入部分４は開口部２０３に確実に嵌合し、燃料給油器具１の回転が防止され、装着状態を安定させることができる。   6) Since the outer diameter portion of the second insertion portion 4 is tapered, the rubber of the second insertion portion 4 bites into the opening 203 by pushing the second insertion portion 4 into the opening 203. 4 securely fits into the opening 203, prevents rotation of the fuel supply device 1, and stabilizes the mounted state.

７）燃料注ぎ口部分２のラッパ形状を、最上端位置まで燃料を注がれたときの燃料給油器具１内の燃料の重心位置が第１挿入部分３、第２挿入部分４、燃料注ぎ口部分２の中心軸線より下方に位置するような形状としたので、燃料給油器具１内に注がれた燃料の自重による燃料給油器具１の回転ずれが防止され、燃料がこぼれることは無い。   7) The trumpet shape of the fuel spout portion 2 is such that the center of gravity position of the fuel in the fuel supply device 1 when the fuel is poured to the uppermost position is the first insertion portion 3, the second insertion portion 4, and the fuel spout Since the shape is positioned below the central axis of the portion 2, rotation deviation of the fuel supply device 1 due to the weight of the fuel poured into the fuel supply device 1 is prevented, and fuel does not spill.

８）燃料注ぎ口部分２の最上端開口部の周囲に、燃料給油器具１を燃料給油口２００に装着したときに建設機械に向く側を直線部６ａとしたフランジ状の安定板６を設けたので、燃料給油器具１を異なる機種に用いる場合でも、補助具として挿入パイプ８を用い、この挿入パイプ８を燃料給油器具１の第１挿入部分３につなげて、挿入パイプ８を給油口金２０２の開口部２０３からストレーナー２１０内に挿入し、安定板６の直線部６ａを本体カバー１０９に接触させることで、回転方向に安定した状態で燃料給油器具１を装着することができる。   8) Around the uppermost opening of the fuel spout portion 2, there is provided a flange-shaped stabilizing plate 6 having a straight portion 6a on the side facing the construction machine when the fuel filler 1 is attached to the fuel filler 200. Therefore, even when the fuel filler 1 is used for different models, the insertion pipe 8 is used as an auxiliary tool, and the insertion pipe 8 is connected to the first insertion portion 3 of the fuel filler 1 so that the insertion pipe 8 is connected to the fuel filler base 202. By inserting into the strainer 210 from the opening 203 and bringing the straight portion 6a of the stabilizing plate 6 into contact with the main body cover 109, the fuel supply device 1 can be mounted in a stable state in the rotational direction.

なお、以上の実施の形態においては、燃料給油器具１の全体を柔軟性のあるラバーで構成したが、燃料注ぎ口部分２を柔軟性のあるラバーで構成し、第１及び第２挿入部分３，４はプラスチック等、その他の材質で構成してもよい。この場合でも、燃料注ぎ口部分２を柔軟性のあるラバーで構成されている限り、燃料給油時に燃料容器を燃料給油器具１に乗せたり、ぶつけたりしても、燃料注ぎ口部分２のラバーが変形するので、燃料給油口２００を損傷させることは無い。また、第１及び第２挿入部分３，４をプラスチック等、比較的強度のある材質で構成した場合は、第１挿入部分３は必ずしもストレート形状である必要はなく、例えば挿入しやすいテーパー形状であってもよい。この場合は、第１及び第２挿入部分３，４の支持スパンは短くなるが、第１及び第２挿入部分３，４自体の強度で装着状態を安定させることができる。更に、装着状態での軸線Ａ回りの回り止めのため、第２挿入部分の材質をラバーとしかつ第２挿入部分４の外径部をテーパー形状として、第２挿入部分を開口部２０３に確実に嵌合させる構成としたが、別の構成で装着状態での回り止めをしてもよい。例えば、掛かり溝２０６，２０６を利用し、第２挿入部分４の外径部に溝２０６，２０６にはまりこむ凸部を形成しても、燃料給油器具１の回転を防止することができる。この場合は、第２挿入部分の材質はラバーでなくてもよいし、その外径部もテーパー形状でなくてもよい。   In the above embodiment, the fuel refueling instrument 1 as a whole is made of flexible rubber. However, the fuel spout portion 2 is made of flexible rubber, and the first and second insertion portions 3 are made. , 4 may be made of other materials such as plastic. Even in this case, as long as the fuel spout portion 2 is composed of a flexible rubber, the fuel spout portion 2 rubber will not be affected even if the fuel container is placed on or hit the fuel refueling device 1 during fuel refueling. Since it is deformed, the fuel filler opening 200 is not damaged. When the first and second insertion portions 3 and 4 are made of a relatively strong material such as plastic, the first insertion portion 3 does not necessarily have a straight shape. For example, the first and second insertion portions 3 and 4 have a tapered shape that is easy to insert. There may be. In this case, the support span of the first and second insertion portions 3 and 4 is shortened, but the mounting state can be stabilized by the strength of the first and second insertion portions 3 and 4 themselves. Further, in order to prevent rotation around the axis A in the mounted state, the material of the second insertion portion is made of rubber, and the outer diameter portion of the second insertion portion 4 is tapered, so that the second insertion portion is securely in the opening 203. Although it was set as the structure fitted, you may prevent rotation in a mounting state by another structure. For example, even if the hook grooves 206 and 206 are used to form convex portions that fit into the grooves 206 and 206 on the outer diameter portion of the second insertion portion 4, the rotation of the fuel supply device 1 can be prevented. In this case, the material of the second insertion portion may not be rubber, and the outer diameter portion may not be tapered.
