Description

本発明は、クレーンやホイスト等の移動する負荷に電気を供給する絶縁トロリー線集電装置に関するものである。   The present invention relates to an insulated trolley wire current collector that supplies electricity to a moving load such as a crane or a hoist.

従来より、クレーンやホイスト等の移動する負荷に電気を供給する絶縁トロリー線集電装置が用いられている（例えば特許文献１参照）。絶縁トロリー線集電装置は、天井等の造営材に取付けられる絶縁トロリー線と、移動する負荷に取付けられる集電子とで主体が構成され、集電子が絶縁トロリー線の導体に摺接して、導体から集電子を介して移動する負荷に電気を供給するものである。集電子は、絶縁トロリー線に摺接する集電子片と、集電子片に設けられる軸を受ける集電子側の回転座と、負荷に設けられる軸を受ける負荷側の回転座と、両端部が前記集電子側の回転座と負荷側の回転座とにそれぞれ回動可能に連結されるアームと、を備えている。   Conventionally, an insulated trolley wire current collector that supplies electricity to a moving load such as a crane or a hoist has been used (see, for example, Patent Document 1). An insulated trolley wire current collector is composed mainly of an insulated trolley wire attached to a construction material such as a ceiling and a current collector attached to a moving load, and the current collector is in sliding contact with a conductor of the insulated trolley wire, Electricity is supplied to the load that moves from the current collector through the current collector. The current collector includes a current collector piece that is in sliding contact with the insulated trolley wire, a current collector side rotary seat that receives a shaft provided on the current collector piece, a load side rotary seat that receives a shaft provided on a load, and both ends of the current collector And an arm that is rotatably connected to the current-collection-side rotary seat and the load-side rotary seat.

この集電子は、移動する負荷に追従しながら絶縁トロリー線に摺接するのであるが、負荷の移動経路と絶縁トロリー線の配置経路とは一致しないため、集電子が絶縁トロリー線から外れることがないように、移動する負荷に対して位置および向きが可動となるように上記のような構成とするものである。   The current collector is in sliding contact with the insulated trolley wire while following the moving load, but the current collection path does not coincide with the arrangement path of the insulated trolley wire, so the current collector does not come off the insulated trolley wire. Thus, it is set as the above structures so that a position and direction may become movable with respect to the moving load.

絶縁トロリー線は、移動する負荷の移動経路に沿って配置されるが、種々の制約から、連続した一つの絶縁トロリー線ではなく、所々で分断された複数の絶縁トロリー線で構成されることが一般的に良く行われている。この場合、集電子は、分断された複数の絶縁トロリー線間を移って摺接する必要がある。   The insulated trolley wire is arranged along the movement path of the moving load, but due to various restrictions, it may be composed of a plurality of insulated trolley wires that are divided in some places instead of one continuous insulated trolley wire. Generally done well. In this case, the current collector needs to move between the plurality of separated insulated trolley wires to be in sliding contact.

絶縁トロリー線は、絶縁枠体に形成される溝の底部に導体を配置して構成してあり、前記溝の内壁が集電子片のガイドとなる。集電子が、一絶縁トロリー線から、別の分断されている絶縁トロリー線へと乗り移る場合には、その集電子片が乗り移る先の絶縁トロリー線の溝内に収容される必要があるが、集電子は上述したように負荷に対して位置および角度が一定の範囲内で可動となっていて、集電子片が乗り移る先の絶縁トロリー線の溝内に確実に収容され得ないものであった。
実公平７−２２９６５号公報 The insulating trolley wire is configured by arranging a conductor at the bottom of a groove formed in the insulating frame, and the inner wall of the groove serves as a guide for the current collecting piece. When the current collector is transferred from one insulated trolley wire to another separated insulated trolley wire, the current collector piece needs to be accommodated in the groove of the insulated trolley wire to which the current collector piece is transferred. As described above, the electrons are movable within a certain range and position with respect to the load, and the electrons cannot be reliably accommodated in the groove of the insulating trolley wire to which the current collecting piece is transferred.

負荷Ｆ側の回転座４は、負荷Ｆに取付られる取付ベース７に固定される軸４０が内部に挿通される略筒状をしたもので、上述した集電子１側の回転座３と略同様の形状をしている。図７（ａ）に示すように集電子１すなわち、負荷Ｆ側の回転座４、アーム５、集電子１側の回転座３、集電子片ケーシング１０が負荷Ｆ側に固定される軸４０回りに回転自在となっている。負荷Ｆ側に固定される軸４０は抜け止め手段（図示せず）を備えており、負荷Ｆ側の回転座４から抜け落ちるのが防止されている。   The rotary seat 4 on the load F side has a substantially cylindrical shape into which a shaft 40 fixed to the mounting base 7 attached to the load F is inserted, and is substantially the same as the rotary seat 3 on the collector 1 side described above. It has the shape of As shown in FIG. 7 (a), the current collector 1, that is, the rotation seat 4 on the load F side, the arm 5, the rotation seat 3 on the current collector 1 side, and the shaft 40 around which the current collector piece casing 10 is fixed on the load F side. It is freely rotatable. The shaft 40 fixed to the load F side is provided with a retaining means (not shown), and is prevented from falling off from the rotary seat 4 on the load F side.

負荷Ｆに取付けられる取付ベース７は、負荷Ｆの表面に取付けられる取付片７１と、取付片７１から負荷Ｆの表面から離れる方向に突出する少なくとも二つの突出片７２と、少なくとも二つの突出片７２の突出端部間に架設される被着片７３とからなるもので、本実施形態では、間隔を隔てて負荷Ｆの表面に取付けけられる二つの取付片７１と、二つの取付片７１の対向する端部からそれぞれ負荷Ｆの表面から離れる方向に連設される二つの突出片７２と、両突出片７２の突出端部間に架設される被着片７３とからなる、長手方向と直交する断面における形状がハット状をしたものである。取付片７１には、負荷Ｆにビス等の固着具により固定するための固着具挿通穴７１ａが穿設してある。このような取付ベース７の構成により、取付ベース７を負荷Ｆの表面に固定した状態で、取付ベース７の被着片７３を負荷Ｆの表面から空間をあけて位置させることができる。   The attachment base 7 attached to the load F includes an attachment piece 71 attached to the surface of the load F, at least two protrusion pieces 72 protruding from the attachment piece 71 in a direction away from the surface of the load F, and at least two protrusion pieces 72. In this embodiment, two attachment pieces 71 that are attached to the surface of the load F with an interval therebetween, and the two attachment pieces 71 are opposed to each other. Perpendicular to the longitudinal direction, which is composed of two projecting pieces 72 connected in a direction away from the surface of the load F from the respective end portions and the adherend pieces 73 installed between the projecting end portions of both projecting pieces 72. The cross-sectional shape is a hat shape. The attachment piece 71 is provided with a fastener insertion hole 71a for fixing to the load F with a fastener such as a screw. With such a configuration of the mounting base 7, the attached piece 73 of the mounting base 7 can be positioned with a space from the surface of the load F in a state where the mounting base 7 is fixed to the surface of the load F.

そして、取付ベース７の被着片７３には、負荷Ｆ側に取付けられる軸４０を挿通して固定するための固着穴７３ａが穿設してある。また、負荷Ｆ側に取付けられる軸４０には、負荷Ｆ側の回転座４から突出する部分に雄ねじ部４１が形成してあり、前記取付ベース７の被着片７３の固着穴７３ａに前記軸４０に形成した雄ねじ部４１を挿通すると共に、雄ねじ部４１にナット４２を螺着して前記軸４０を取付ベース７に締結固定する。本実施形態ではこの時、負荷Ｆ側の軸４０とともに以下に説明する回転抑制部６を取付ベース７に締結固定するものである。   And the adhering piece 73 of the attachment base 7 is drilled with a fixing hole 73a for inserting and fixing the shaft 40 attached to the load F side. The shaft 40 attached to the load F side is formed with a male screw portion 41 at a portion protruding from the rotary seat 4 on the load F side, and the shaft is inserted into the fixing hole 73a of the attachment piece 73 of the attachment base 7. The male screw portion 41 formed on the screw 40 is inserted, and a nut 42 is screwed onto the male screw portion 41 to fasten and fix the shaft 40 to the mounting base 7. In this embodiment, at this time, together with the shaft 40 on the load F side, the rotation suppressing portion 6 described below is fastened and fixed to the mounting base 7.

回転抑制部６は、図６に示すように、連結片６１と、連結片６１の両端部からそれぞれ連設されるばね片６０とからなる断面略コ字状をしたものである。回転抑制部６は、図７（ｂ）に示すように前記ばね片６０がアーム５の側面（図中の斜線部５１）の両側から弾性的に当接することで、図７（ａ）に示すようにアーム５および負荷Ｆ側の回転座４が前記負荷Ｆ側の軸４０の回りに回転するのを抑えるものである。   As shown in FIG. 6, the rotation suppressing portion 6 has a substantially U-shaped cross section including a connecting piece 61 and spring pieces 60 respectively connected from both ends of the connecting piece 61. As shown in FIG. 7 (b), the rotation suppressing portion 6 is shown in FIG. 7 (a) by elastically contacting the spring pieces 60 from both sides of the side surface (shaded portion 51 in the drawing) of the arm 5. As described above, the arm 5 and the load seat 4 on the load F side are prevented from rotating around the shaft 40 on the load F side.

回転抑制部６の連結片６１には固着具挿通穴６１ａが穿設してあり、この連結片６１を取付ベース７の被着片７３上に重ねて合わせて、連結片６１の固着具挿通穴６１ａを被着片７３の固着穴７３ａに連通させ、負荷Ｆ側の軸４０の雄ねじ部４１を上述したようにナット４２により締結固定すると共に、回転抑制部６も固定するものである（図８（ａ）参照）。これにより、集電子１を取付ベース７に取付けるための固着具（雄ねじ部４１とナット４２）で回転抑制部６を取付けることができて、回転抑制部６を取付ベース７に取付けるための固着具を別に設ける必要がないと共に、回転抑制部６の取付ベース７に対する位置決めも容易に行うことが可能となるものである。   The connecting piece 61 of the rotation suppressing portion 6 is provided with a fastener insertion hole 61a. The connecting piece 61 is overlapped on the attachment piece 73 of the mounting base 7 so that the fixing tool insertion hole of the connection piece 61 is aligned. 61a is communicated with the fixing hole 73a of the adherend piece 73, and the male screw portion 41 of the shaft 40 on the load F side is fastened and fixed by the nut 42 as described above, and the rotation suppressing portion 6 is also fixed (FIG. 8). (See (a)). Thereby, the rotation suppressing part 6 can be attached by the fixing tool (the male screw part 41 and the nut 42) for attaching the current collector 1 to the mounting base 7, and the fixing tool for attaching the rotation suppressing part 6 to the mounting base 7. In addition, it is possible to easily position the rotation suppressing portion 6 with respect to the mounting base 7.

絶縁トロリー線２は、上述したように複数本（本実施形態では４本）平行に並設するもので、前記絶縁トロリー線２の本数に合わせて集電子１の数が決まり、この集電子１の数に合わせて該集電子１が取付けられる取付ベース７の被着片７３の長さを変えるものである。すなわち、取付ベース７の被着片７３の長さは、一つの集電子１の取付け幅×集電子１の数となり、本実施形態では図８（ａ）に示すように集電子１の取付け幅四つ分の長さとなると共に、各集電子１の取付け部分にそれぞれ固着穴７３ａが穿設してある。集電子１の取付け幅は回転抑制部６の連結片６１の幅（両ばね片６０間の距離）となる。そして、各集電子１ごとの回転抑制部６の連結片６１を取付ベース７の被着片７３上に重ねて、連結片６１の固着具挿通穴６１ａを被着片７３の固着穴７３ａにそれぞれ連通させ、軸４０の雄ねじ部４１をナット４２により締結固定するのであるが、この時、図８（ｂ）（ｃ）に示すように隣接する回転抑制部６のばね片６０が互いに当接するようにして固定することで、各回転抑制部６自体の回転防止のための手段を特に設けずに済むものである。すなわち、回転抑制部６を他の回転抑制部６と当接させずに固定した場合には、集電装置を使用するにつれて回転抑制部６を締結固定しているナット４２が緩んで回転抑制部６が取付ベース７に対して回転してしまうが、隣接する回転抑制部６のばね片６０が互いに当接するようにして固定することで、当接する回転抑制部６が互いに回転抑制部６が回転するのを防止することになる。本実施形態では、取付ベース７の被着片７３には、並設される回転抑制部６の両外端のばね片６０の外面に当接して位置決めする規制片７４が突設してあり、回転抑制部６の取付ベース７に対する位置決めおよび回転防止をより一層確実にしてある。   The insulating trolley wires 2 are arranged in parallel (in the present embodiment, four) in parallel as described above, and the number of current collectors 1 is determined according to the number of the insulating trolley wires 2. The length of the adherend piece 73 of the mounting base 7 to which the current collector 1 is mounted is changed in accordance with the number of the current collectors 1. That is, the length of the adherend piece 73 of the mounting base 7 is the mounting width of one collector 1 × the number of collectors 1. In this embodiment, the mounting width of the collector 1 is shown in FIG. In addition to the length of four, fixing holes 73a are formed in the attachment portions of the current collectors 1, respectively. The mounting width of the current collector 1 is the width of the connecting piece 61 of the rotation suppressing unit 6 (the distance between the two spring pieces 60). And the connection piece 61 of the rotation suppression part 6 for every collector 1 is piled up on the to-be-attached piece 73 of the attachment base 7, and the fixing tool penetration hole 61a of the connection piece 61 is set to the fixing hole 73a of the to-be-attached piece 73, respectively. The male screw portion 41 of the shaft 40 is fastened and fixed by the nut 42, and at this time, as shown in FIGS. 8B and 8C, the spring pieces 60 of the adjacent rotation suppressing portions 6 come into contact with each other. By fixing in this manner, it is not necessary to provide a means for preventing the rotation of each rotation suppression unit 6 itself. That is, when the rotation suppression unit 6 is fixed without being brought into contact with another rotation suppression unit 6, the nut 42 that fastens and fixes the rotation suppression unit 6 is loosened as the current collector is used. 6 rotates with respect to the mounting base 7, but the spring pieces 60 of the adjacent rotation suppression units 6 are fixed so that they are in contact with each other, so that the rotation suppression units 6 that are in contact with each other rotate the rotation suppression unit 6 with each other. Will be prevented. In the present embodiment, the attachment piece 73 of the mounting base 7 is provided with a restriction piece 74 that contacts and positions the outer surfaces of the spring pieces 60 at both outer ends of the rotation suppressing portions 6 provided side by side, Positioning and rotation prevention of the rotation suppressing portion 6 with respect to the mounting base 7 are further ensured.

上記のような回転抑制部６を設けることで、例えば図５（ｂ）に示すように絶縁トロリー線２を壁面に横向きに配置した場合、負荷Ｆの側面に横向きに取付ベース７を固定すると共に、取付ベース７に集電子１をその集電子片１１が横向きとなるように取付けることとなるが、この時図７（ａ）に示すように集電子１すなわち負荷Ｆ側の回転座４、アーム５、集電子１側の回転座３、集電子片ケーシング１０が負荷Ｆ側に固定される軸４０回りに回転自在となっていて、集電子１の自重によって集電子片１１が下向きとなるように回転してしまうのを、回転抑制部６によって集電子１が前記軸４０回りに回転するのを抑えて、集電子片１１が下向きにならず所定の方向を向くように姿勢を維持することができて、乗り移る先の絶縁トロリー線２の溝２２内に確実に安定して収容することが可能となる。この結果、乗り移る際の集電子１の速度が１２０ｍ／分でも安定して乗り移ることが可能となった。   By providing the rotation suppression unit 6 as described above, for example, when the insulated trolley wire 2 is disposed laterally on the wall surface as shown in FIG. 5B, the mounting base 7 is fixed laterally on the side surface of the load F. The current collector 1 is attached to the attachment base 7 so that the current collector piece 11 faces sideways. At this time, as shown in FIG. 7 (a), the current collector 1, that is, the rotary seat 4 on the load F side, the arm 5. The rotary seat 3 on the current collector 1 side and the current collector piece casing 10 are rotatable around a shaft 40 fixed on the load F side so that the current collector piece 11 faces downward due to its own weight. To prevent the current collector 1 from rotating around the axis 40 by the rotation suppression unit 6 and maintain the posture so that the current collector piece 11 does not face downward and faces a predetermined direction. Insulated trolley wire where you can transfer It is possible to the groove 22 accommodates reliably and stably. As a result, it is possible to transfer stably even when the speed of the current collector 1 is 120 m / min.

回転抑制部６は、上記のように負荷Ｆ側に固定される軸４０回りの集電子１の回転は抑えるが、アーム５の回転座３、４に対する回動に対してはフリーとなっていて、負荷Ｆに追従する集電子１が絶縁トロリー線２から外れないように負荷Ｆに対する自由度を有している。そして、アーム５が回転座３、４に対して上方に回動した際、アーム５（本実施形態では取付ベース７から遠い方のアーム５）が回転抑制部６のばね片６０から脱する場合がある。この時、回転抑制部６のばね片６０間から脱したアーム５がばね片６０の先端部から再び両ばね片６０間に入る際に入り易いようにガイドすべく、ばね片６０の先端部に曲げ部６２が設けてある。曲げ部６２は、図６に示すように、各ばね片６０の先端部に、もう一方のばね片６０から遠ざかる方向に傾斜するように屈曲して形成してある。本実施形態では、一方のばね片６０の曲げ部６２を一方の半部に形成すると共に、他方のばね片６０の曲げ部６２を他方の半部に形成して、側面視において互い違い千鳥状となるように形成してある。これにより、図８（ｂ）（ｃ）に示すように、隣接する回転抑制部６のばね片６０が互いに当接するようにして固定する際、当接するばね片６０の曲げ部６２が干渉するのを回避することが可能となる。   The rotation suppressing unit 6 suppresses the rotation of the current collector 1 around the shaft 40 fixed on the load F side as described above, but is free for the rotation of the arm 5 relative to the rotating seats 3 and 4. The current collector 1 that follows the load F has a degree of freedom with respect to the load F so that it does not come off the insulated trolley wire 2. When the arm 5 pivots upward with respect to the rotary seats 3 and 4, the arm 5 (the arm 5 far from the mounting base 7 in this embodiment) is detached from the spring piece 60 of the rotation suppression unit 6. There is. At this time, the arm 5 removed from between the spring pieces 60 of the rotation suppressing portion 6 is guided to the tip of the spring piece 60 so that the arm 5 can easily enter when entering the space between the two spring pieces 60 from the tip of the spring piece 60 again. A bent portion 62 is provided. As shown in FIG. 6, the bent portion 62 is formed at the tip end portion of each spring piece 60 by being bent so as to be inclined away from the other spring piece 60. In the present embodiment, the bent portion 62 of one spring piece 60 is formed in one half, and the bent portion 62 of the other spring piece 60 is formed in the other half, which is staggered in a side view. It is formed so that Thus, as shown in FIGS. 8B and 8C, when the spring pieces 60 of the adjacent rotation suppressing portions 6 are fixed so as to contact each other, the bent portions 62 of the spring pieces 60 that contact each other interfere with each other. Can be avoided.

また本実施形態では、負荷Ｆ側の回転座４と、集電子片ケーシング１０の前記負荷Ｆ側の回転座４側の端部とを、自在に伸長して復元力が生じるセンタリング部材８で連結してある。センタリング部材８は、本実施形態のようにコイルばねやその他ゴムのようなものでもよく、特に限定されない。   In the present embodiment, the rotating seat 4 on the load F side and the end of the current collecting piece casing 10 on the rotating seat 4 side on the load F side are connected by a centering member 8 that freely expands to generate a restoring force. It is. The centering member 8 may be a coil spring or other rubber like the present embodiment, and is not particularly limited.

集電子片ケーシング１０は上述したように、図９（ａ）に示すように集電子１側の回転座３の軸４０回りに左右方向に回転自在となると共に、図９（ｂ）に示すように集電子片ケーシング１０の枢支部１３において上下方向に回転自在となっており、センタリング部材８を設けなければ特に復元力が生じないため、集電子片１１の向きが任意に変化するものの変化したままとなってしまう。そこで本実施形態のようにセンタリング部材８を設けたことで、センタリング部材８の復元力によって集電子片１１の向きが維持されることとなる。   As described above, the current collector piece casing 10 is rotatable in the left-right direction around the axis 40 of the rotary seat 3 on the current collector 1 side, as shown in FIG. 9A, and as shown in FIG. 9B. In addition, the pivoting portion 13 of the current collector piece casing 10 is rotatable in the vertical direction, and unless the centering member 8 is provided, no restoring force is generated. It will remain. Therefore, by providing the centering member 8 as in the present embodiment, the orientation of the current collecting piece 11 is maintained by the restoring force of the centering member 8.
