従来から、例えば天井走行クレーンやホイスト等の移動機械への電力供給用として絶縁トロリが用いられている。
この絶縁トロリの一般的なものとして特許文献１に記載された形状のものがある。
これは図６が示すように、導体１の一部を集電子２が摺動する被摺動面３として露出させた状態で導体１に絶縁カバー４を被せたもので、この被摺動面３を摺動する集電子２が脱線しないように、前記絶縁カバー４には被摺動面３の両側に位置する部分に一対の脚部５、５が設けられている。 Conventionally, an insulated trolley has been used for power supply to mobile machines such as overhead traveling cranes and hoists.

ところで図６が示す従来の絶縁トロリの場合、被摺動面３の両側に集電子２の脱線防止用に、一対の脚部５、５があるにも関わらず、例えばこの絶縁トロリに対して集電子２を介して給電されながら移動するクレーン等の移動体装置自体の振動や、この移動体の走行中の不測の揺れによって、集電子２が絶縁トロリの被摺動面３から脚部５を乗り越えて脱線することがある。
あるいはまた、周囲の温度変化等の環境変化によって、絶縁トロリ自身が伸びたりして蛇行し、その結果、集電子２が絶縁トロリの被摺動面３から外れ、一対の脚部５、５を乗り越えて脱線することもある。 By the way, in the case of the conventional insulated trolley shown in FIG. 6, although there are a pair of legs 5 and 5 for preventing derailment of the current collector 2 on both sides of the sliding surface 3, for example, The current collector 2 moves from the sliding surface 3 of the insulating trolley to the leg portion 5 due to vibration of the mobile device itself such as a crane that moves while being supplied with power through the current collector 2 or unexpected vibration while the mobile body is traveling. You may get over the road and derail.
Alternatively, the insulation trolley itself stretches and meanders due to an environmental change such as a change in ambient temperature, and as a result, the current collector 2 comes off the sliding surface 3 of the insulation trolley, and the pair of legs 5 and 5 are attached. You may get over and derail.

このように集電子２が脱線すると、集電子２は所定圧力で被摺動面３に押さえ付けられながら移動しているため、脱線した集電子２は導体１側に跳び上がった状態で走行することになる。その結果、この走行する集電子２が絶縁トロリを天井等に支持しているハンガー等の絶縁トロリ取り付け装置、あるいはこの絶縁トロリ取り付け装置に隣接して他の設備があった場合には、これらにも衝突し、これら装置や他設備を破損させることもある。 When the current collector 2 derails in this way, the current collector 2 moves while being pressed against the sliding surface 3 with a predetermined pressure, and therefore the derailed current collector 2 travels in a state of jumping up to the conductor 1 side. It will be. As a result, if the traveling current collector 2 has an insulating trolley mounting device such as a hanger that supports the insulating trolley on the ceiling, or other equipment adjacent to the insulating trolley mounting device, May collide and damage these devices and other equipment.

そこで本発明の目的は、集電子が導体の被摺動面から脱線し難く、それ故、絶縁トロリの取り付け装置等を破損させることのない絶縁トロリを提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide an insulating trolley in which the current collector is not easily derailed from the sliding surface of the conductor, and thus does not damage the mounting device for the insulating trolley.

前記目的を達成すべく請求項１記載の絶縁トロリは、導体上に被せられた絶縁カバーの一対の脚部間に前記導体の一部を集電子の被摺動面として露出させた絶縁トロリにおいて、前記絶縁カバーの一対の脚部は外方に向かって、前記脚部の成す角度が９０度〜１２０度になるように扇形に開く開脚部からなる脱線防止カバーを有していることを特徴とするものである。 In order to achieve the above object, the insulating trolley according to claim 1, wherein a part of the conductor is exposed as a sliding surface of the current collector between a pair of legs of the insulating cover placed on the conductor. The pair of leg portions of the insulating cover has a derailment prevention cover including an open leg portion that opens in a fan shape so that an angle formed by the leg portions is 90 degrees to 120 degrees toward the outside. It is a feature.

このようにしてなる請求項１記載の絶縁トロリによれば、絶縁カバーの一対の脚部には外方に向かって、前記脚部の成す角度が９０度〜１２０度になるように扇形に開く開脚部からなる脱線防止カバーが設けられているので、被摺動面から外れた集電子は前記脱線防止カバーに案内されて元の位置、すなわち被摺動面に戻される。それ故、集電子が導体の被摺動面から脱線し続けることはなくなる。しかも仮に一時的に脱線したとしても、脱線防止カバーにより導体側上方へ跳ね上がることはなくなるから、絶縁トロリの取り付け装置類に衝突して、これらを破損させる恐れもなくなる。 According to the insulating trolley according to claim 1, the pair of legs of the insulating cover opens outward in a fan shape so that the angle formed by the legs is 90 degrees to 120 degrees. Since the derailment prevention cover comprising the open leg portion is provided, the current collector that has come off the sliding surface is guided by the derailment prevention cover and returned to its original position, that is, the sliding surface. Therefore, the current collector does not continue to derail from the sliding surface of the conductor. Moreover, even if the cable is temporarily derailed, the derailment prevention cover does not jump up upward on the conductor side, so that there is no possibility of colliding with the mounting devices of the insulating trolley and damaging them.

以上のように本発明によれば、集電子が導体の被摺動面から脱線し難く、それ故、絶縁トロリの取り付け装置類を破損させることのない絶縁トロリを提供することができる。 As described above, according to the present invention, it is possible to provide an insulating trolley in which the current collector is not easily derailed from the sliding surface of the conductor, and therefore the insulating trolley mounting apparatus is not damaged.

以下に本発明の絶縁トロリを図を用いて詳細に説明する。尚、前述した図６と同じものには同じ符号を付し、詳細な説明は省略する。 The insulating trolley of the present invention will be described below in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the same thing as FIG. 6 mentioned above, and detailed description is abbreviate | omitted.

図１は本発明の絶縁トロリの一実施例を示す横断面図、図２は、図１において、集電子が導体の被摺動面から脱線しかけた状態を示す横断面図である。
図１が示すように、本発明の絶縁トロリは、導体１に、この導体１の被摺動面３を露出させた状態で絶縁カバー４を被せたもので、この絶縁トロリの特徴、より具体的には絶縁カバー４の特徴は、被摺動面３の両側に位置する一対の脚部５、５は、基端部の、脚部が互いに並行な基端脚部７、７の先端方向に、外方に向かって扇形に開く開脚部からなる脱線防止カバー８、８を有している点にある。 FIG. 1 is a cross-sectional view showing an embodiment of an insulating trolley according to the present invention, and FIG. 2 is a cross-sectional view showing a state in which the current collector is derailed from the sliding surface of the conductor in FIG.
As shown in FIG. 1, the insulating trolley of the present invention is obtained by covering the conductor 1 with the insulating cover 4 in a state where the sliding surface 3 of the conductor 1 is exposed. Specifically, the insulating cover 4 is characterized in that the pair of leg portions 5 and 5 positioned on both sides of the sliding surface 3 are the base end portions and the distal end directions of the base end leg portions 7 and 7 parallel to each other. In addition, there is a derailment prevention cover 8, 8 comprising an open leg portion that opens in a fan shape toward the outside.

尚、扇形の開脚部からなる脱線防止カバー８、８の部分の角度θは、９０度〜１２０度の範囲が最適である。
このように脚部５、５において、その基端部の互いに並行な基端脚部７、７の先に脱線防止カバー８、８を設けておくと、仮に図２が示すように何らかの理由で集電子２が導体１の被摺動面３から外れても、扇形をした一対の脱線防止カバー８、８により集電子２の上方への跳ね上がりを防止でき、脱線防止カバー８、８の内側斜面に沿って集電子２を元の位置、すなわち被摺動面３へと容易に復帰させることができる。 It is to be noted that the angle θ of the derailment prevention covers 8 and 8 formed of fan-shaped open legs is optimally in the range of 90 degrees to 120 degrees.
In this way, in the leg portions 5 and 5, if the derailment prevention covers 8 and 8 are provided at the tips of the base end leg portions 7 and 7 parallel to each other at the base end portion, for some reason as shown in FIG. Even if the current collector 2 is detached from the sliding surface 3 of the conductor 1, the pair of fan-shaped derailment prevention covers 8, 8 can prevent the current collector 2 from jumping upward, and the inner slope of the derailment prevention covers 8, 8. Thus, the current collector 2 can be easily returned to the original position, that is, the sliding surface 3.

ところで絶縁カバー４の脚部５、５の基端部の互いに並行な一対の基端脚部７、７の長さは、この絶縁トロリが使用される使用環境に応じて適宜選択すればよい。すなわち、集電子２の脱線防止は一義的にはこの基端脚部７、７で行うため、振動の激しい場所で使用される絶縁トロリにあっては少し長めに基端脚部７、７を設定すればよい。 By the way, the length of the pair of base end leg portions 7 and 7 parallel to each other of the base end portions of the leg portions 5 and 5 of the insulating cover 4 may be appropriately selected according to the use environment in which the insulating trolley is used. That is, since the derailment prevention of the current collector 2 is primarily performed by the base end legs 7 and 7, the base end legs 7 and 7 are slightly longer in the insulating trolley used in the place where the vibration is intense. You only have to set it.

図３、図４は本発明の絶縁トロリの別の実施例を示す横断面図である。各々導体１の形状に応じて絶縁カバー４の断面形状が選択される。
但し、いずれの形状のものにあっても絶縁カバー４の脚部５、５は、その基端脚部７、７の先に外方に向って扇形に開く開脚部、すなわち脱線防止カバー８、８を有していて、集電子２の被摺動面３からの脱線を防止できるようになっている。 3 and 4 are cross-sectional views showing another embodiment of the insulating trolley of the present invention. The cross-sectional shape of the insulating cover 4 is selected according to the shape of each conductor 1.
However, regardless of the shape, the legs 5, 5 of the insulating cover 4 are open leg portions that open in a fan shape toward the ends of the base end legs 7, 7, that is, the derailment prevention cover 8. , 8 so that the current collector 2 can be prevented from derailing from the sliding surface 3.

図５は本発明の絶縁トロリの、応用例を示す横断面図である。
図５が示す絶縁トロリの特徴は、絶縁カバー４の一対の脚部５、５は、その内側に集電子２が被摺動面３から外れた場合に係止可能な凹部９を各々有していて、この凹部９の底には、脱線してこの凹部９に係止された集電子２を検知するために、検知線１０が、導体の一部を露出した状態で埋設されている点にある。 FIG. 5 is a cross-sectional view showing an application example of the insulating trolley of the present invention.
The insulating trolley shown in FIG. 5 is characterized in that each of the pair of legs 5 and 5 of the insulating cover 4 has a recess 9 that can be locked when the current collector 2 is detached from the sliding surface 3 inside thereof. In order to detect the current collector 2 derailed and locked to the recess 9, a detection line 10 is embedded in the bottom of the recess 9 with a part of the conductor exposed. It is in.

このように脚部５、５の内側に凹部９を設け、その部分に検知線１０を導体を露出した状態で埋め込んでおけば、仮に集電子２が被摺動面３から外れた場合でも、外れた集電子２がこの凹部９に係止されるから、集電子２と検知線１０の導体が接触すれば、両者間に電気的導通が生じ、これを常時検知できる状態にしておけば、集電子２が被摺動面３から脱線したことを常時監視することができる。 Thus, if the concave portion 9 is provided on the inner side of the leg portions 5 and 5 and the detection line 10 is embedded in the exposed portion of the conductor, even if the current collector 2 is detached from the sliding surface 3, Since the detached current collector 2 is locked in the recess 9, if the current collector 2 and the conductor of the detection line 10 come into contact with each other, electrical continuity occurs between them, and if this can be detected at all times, It can always be monitored that the current collector 2 has derailed from the sliding surface 3.

尚、上記実施例においては、脚部５、５の内側に設けた凹部９に導体を露出した状態で検知線１０を埋め込んで検知手段としたが、検知手段はこれに限定されるものではなく、例えば導体を露出した２本の導体を並行に配置しておき、この２本の導体を被摺動面３から外れた集電子２で短絡させ、集電子２の脱線を検知する検知手段もある。もちろんこれ以外の検知手段であってもよいことはいうまでもない。 In the above-described embodiment, the detection line 10 is embedded with the conductor exposed in the recess 9 provided inside the legs 5 and 5, and the detection means is used. However, the detection means is not limited to this. For example, there is also a detecting means for arranging two conductors with exposed conductors in parallel and short-circuiting the two conductors with the current collector 2 deviated from the sliding surface 3 to detect derailment of the current collector 2. is there. Of course, other detection means may be used.

以上述べたように、本発明によれば、集電子が導体の被摺動面から脱線し難く、それ故、絶縁トロリの取り付け装置類を破損させることのない絶縁トロリを提供することができる。 As described above, according to the present invention, it is possible to provide an insulating trolley in which the current collector is not easily derailed from the sliding surface of the conductor, and therefore does not damage the mounting device of the insulating trolley.
