Description

明 細 書 傾斜部高速エスカレー夕一 技術分野  Memorandum Description High-speed escalation at slope
この発明は、 中間傾斜部における踏段の移動速度が上側乗降口部及び下側乗降 口部における踏段の移動速度よりも速い傾斜部高速エス力レー夕一に関するもの である。 背景技術  TECHNICAL FIELD The present invention relates to a high-speed escaping race on a slope where the speed of movement of the steps at the intermediate slope is faster than the speed of movement of the steps at the upper and lower entrances. Background art
近年、 地下鉄の駅等には、 高揚程のエスカレー夕一が数多く設置されている。 この種のエスカレーターでは、 乗客は踏段に静止した状態で長い時間立っていな ければならず、 不快感を覚える乗客が多い。 このため、 高速度で運行するエス力 レーターが開発されているが、 その運行速度には、 乗客が安全に乗り降りするた めの上限値がある。  In recent years, many high-rise escalators have been installed at subway stations. In this type of escalator, passengers must stand still for long periods of time on the steps, and many passengers feel uncomfortable. For this reason, escalators that operate at high speeds have been developed, but there is an upper limit to the speed at which passengers can get on and off safely.
これに対し、 乗客が乗り降りする上下乗降口部では低速運行、 上曲部及び下曲 部では加減速運行、 中間傾斜部では高速運行することにより、 エスカレー夕一に 乗っている時間を短縮することが可能な傾斜部高速エスカレーターが提案されて いる。 このような傾斜部高速エスカレーターは、 例えば特開昭 5 1—1 1 6 5 8 6号公報に示されている。  On the other hand, reduce the time spent in Escalai by running at low speed at the upper and lower entrances where passengers get on and off, accelerating and decelerating at upper and lower bends, and operating at high speed at intermediate slopes.

Step 2 includes a tread plate 8 for carrying passengers, a riser 9 erected at one end of the tread plate 8 in the front-rear direction, a drive roller shaft 10, and a pair of drive rollers 11 rotatable around a drive roller shaft 10. It has a follow roller shaft 12 and a pair of follow ports 13 rotatable about the follow roller shaft 12. The drive roller 11 rolls along the drive rail 5. The following roller 13 rolls along the following rail 6.
互いに隣接する踏段 2の駆動ローラ軸 1 0は、 一対のリンク機構 （屈折リン ク） 1 4により互いに連結されている。 各リンク機構 1 4は、 第 1ないし第 5の リンク 1 5〜： L 9を有している。  The drive roller shafts 10 of the steps 2 adjacent to each other are connected to each other by a pair of link mechanisms (refraction links) 14. Each link mechanism 14 has first to fifth links 15 to: L9.
第 1のリンク 1 5の一端部は、 駆動ローラ軸 1 0に回動自在に連結されている。 第 1のリンク 1 5の他端部は、 第 3のリンク 1 7の中間部に軸 2 0を介して回動 自在に連結されている。 第 2のリンク 1 6の一端部は、 隣接する踏段 2の駆動口 ーラ軸 1 0に回動自在に連結されている。 第 2のリンク 1 6の他端部は、 第 3の リンク 1 7の中間部に軸 2 0を介して回動自在に連結されている。  One end of the first link 15 is rotatably connected to the drive roller shaft 10. The other end of the first link 15 is rotatably connected to an intermediate portion of the third link 17 via a shaft 20. One end of the second link 16 is rotatably connected to the drive shaft 10 of the adjacent step 2. The other end of the second link 16 is rotatably connected to an intermediate portion of the third link 17 via a shaft 20.
第 1のリンク 1 5の中間部には、 第 4のリンク 1 8の一端部が回動自在に連結 されている。 第 2のリンク 1 6の中間部には、 第 5のリンク 1 9の一端部が回動 自在に連結されている。 第 4及び第 5のリンク 1 8 , 1 9の他端部は、 摺動軸 2 1を介して第 3のリンク 1 7の一端部に連結されている。  One end of a fourth link 18 is rotatably connected to an intermediate portion of the first link 15. One end of a fifth link 19 is rotatably connected to an intermediate portion of the second link 16. The other ends of the fourth and fifth links 18 and 19 are connected to one end of a third link 17 via a sliding shaft 21.
第 3のリンク 1 7の一端部には、 第 3のリンク 1 7の長手方向への摺動軸 2 1 の摺動を案内する案内溝 1 7 aが設けられている。 第 3のリンク 1 7の他端部に は、 回転自在の補助ローラ 2 2が設けられている。 補助ローラ 2 2は、 補助レー ル 7によって案内される。  At one end of the third link 17, a guide groove 17 a for guiding the sliding of the sliding shaft 21 in the longitudinal direction of the third link 17 is provided. A rotatable auxiliary roller 22 is provided at the other end of the third link 17. The auxiliary roller 22 is guided by an auxiliary rail 7.
補助ローラ 2 2が補助レール 7で案内されることにより、 リンク機構 1 4が屈 伸するように変態し、 駆動ローラ軸 1 0の間隔、 即ち隣接する踏段 2相互の間隔 が変化される。 逆に言えば、 隣接する踏段 2相互の間隔が変化するように、 補助 レ一ル 7の軌道が設計されている。 When the auxiliary roller 22 is guided by the auxiliary rail 7, the link mechanism 14 is deformed so as to bend and elongate, and the interval between the drive roller shafts 10, that is, the interval between the adjacent steps 2 is changed. Conversely, adjacent steps 2 are assisted so that the distance between them changes. Rail 7 orbits are designed.
次に、 動作について説明する。 踏段 2の速度は、 隣接する踏段 2の駆動ローラ 軸 1 0の間隔を変化させることにより変化される。 即ち、 乗客が乗り降りする上 側乗降口部 A及び下側乗降口部 Eでは、 駆動ローラ軸 1 0の間隔が最小となり、 踏段 2は低速で移動する。 また、 中間傾斜部 Cでは、 駆動ローラ軸 1 0の間隔が 最大となり、 踏段 2は高速で移動する。 さらに、 上曲部 B及び下曲部 Dでは、 駆 動ローラ軸 1 0の間隔が変化され、 踏段 2は加減速走行する。  Next, the operation will be described. The speed of the step 2 is changed by changing the distance between the drive roller shafts 10 of the adjacent steps 2. That is, at the upper entrance / exit A and the lower entrance / exit E where passengers get on and off, the interval between the drive roller shafts 10 is minimum, and the steps 2 move at low speed. In the middle inclined portion C, the interval between the drive roller shafts 10 is maximum, and the steps 2 move at high speed. Further, in the upper curved portion B and the lower curved portion D, the interval between the driving roller shafts 10 is changed, and the step 2 accelerates and decelerates.
第 1、 第 2、 第 4及び第 5のリンク 1 5 , 1 6， 1 8， 1 9は、 いわゆるパン 夕グラフ式 4連リンク機構を構成しており、 第 3のリンク 1 7を対称軸として第 1及び第 2のリンク 1 5， 1 6のなす角度を大きくしたり小さくしたりすること ができる。 これにより、 第 1及び第 2のリンク 1 5， 1 6に連結された駆動口一 ラ軸 1 0の間隔を変化させることができる。  The first, second, fourth, and fifth links 15, 16, 18, and 19 constitute a so-called pan-graph-type quadruple link mechanism, and the third link 17 is a symmetrical axis. As a result, the angle between the first and second links 15 and 16 can be increased or decreased. As a result, it is possible to change the distance between the drive port shaft 10 connected to the first and second links 15 and 16.
図 8の乗降口部 A, Eでは、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が最小 になっている。 この状態から、 駆動レール 5と補助レール 7との間の間隔を小さ くすると、 雨傘を広げるときの傘の骨組の動作と同様にリンク機構 1 4が動作し、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が大きくなる。  At the entrances A and E in FIG. 8, the distance between the drive roller shafts 10 of the adjacent steps 2 is minimized. In this state, if the distance between the drive rail 5 and the auxiliary rail 7 is reduced, the link mechanism 14 operates in the same manner as the umbrella frame when the umbrella is spread, and the drive roller shaft of the adjacent step 2 The interval of 10 increases.
図 8の中間傾斜部 Cでは、 駆動レール 5と補助レール 7との間の間隔が最小で あり、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が最大となっている。 従って、 この領域で踏段 2の速度は最大となる。 また、 この状態では、 第 1及び第 2のリ ンク 1 5 , 1 6がほぼ一直線上に配置される。  In the middle inclined portion C in FIG. 8, the distance between the drive rail 5 and the auxiliary rail 7 is the smallest, and the distance between the drive roller shafts 10 of the adjacent steps 2 is the largest. Therefore, the speed of step 2 is maximum in this region. In this state, the first and second links 15 and 16 are arranged substantially in a straight line.
しかし、 上記のように構成された従来の傾斜部高速エスカレーターでは、 移動 手摺 2 6の移動速度は、 例えば中間傾斜部 Cにおける踏段 2の移動速度と等しく するなど、 全領域にわたって一定であった。 このため、 中間傾斜部 Cから乗降口 部 A， Eへ移動する場合、 又はその逆の場合に、 移動手摺 2 6と踏段 2との間に 移動量の差が生じ、 移動手摺 2 6を掴みにく くなつてしまう。 発明の開示  However, in the conventional high-speed escalator with the inclined portion configured as described above, the moving speed of the moving handrail 26 is constant over the entire area, for example, equal to the moving speed of the steps 2 in the intermediate inclined portion C. For this reason, when moving from the intermediate slope C to the entrances A and E, or vice versa, a difference in the amount of movement occurs between the moving handrail 26 and the step 2, and the moving handrail 26 is grasped. It becomes difficult. Disclosure of the invention

The intermediate moving handrail 40 has an intermediate linear portion 42 extending parallel to the intermediate inclined portion C. The boundary between the upper handrail device 35, the lower handrail device 37, and the intermediate handrail device 39 is located near the intersection F of the straight line extending the horizontal portion 41 and the straight line extending the intermediate straight portion 42. .
次に、 動作について説明する。 踏段 2の速度は、 隣接する踏段 2の駆動ローラ 軸 1 0の間隔を変化させることにより変化される。 即ち、 乗客が乗り降りする上 側乗降口部 A及び下側乗降口部 Eでは、 駆動ローラ軸 1 0の間隔が最小となり、 踏段 2は低速で移動する。 また、 中間傾斜部 Cでは、 駆動ローラ軸 1 0の間隔が 最大となり、 踏段 2は高速で移動する。 さらに、 上曲部 B及び下曲部 Dでは、 駆 動ローラ軸 1 0の間隔が変化され、 踏段 2は加減速走行する。  Next, the operation will be described. The speed of the step 2 is changed by changing the distance between the drive roller shafts 10 of the adjacent steps 2. That is, at the upper entrance / exit A and the lower entrance / exit E where passengers get on and off, the interval between the drive roller shafts 10 is minimum, and the steps 2 move at low speed. In the middle inclined portion C, the interval between the drive roller shafts 10 is maximum, and the steps 2 move at high speed. Further, in the upper curved portion B and the lower curved portion D, the interval between the driving roller shafts 10 is changed, and the step 2 accelerates and decelerates.
第 1、 第 2、 第 4及び第 5のリンク 1 5 , 1 6， 1 8 , 1 9は、 いわゆるパン 夕グラフ式 4連リンク機構を構成しており、 第 3のリンク 1 7を対称軸として第 1及び第 2のリンク 1 5， 1 6のなす角度を大きくしたり小さくしたりすること ができる。 これにより、 第 1及び第 2のリンク 1 5， 1 6に連結された駆動ロー ラ軸 1 0の間隔を変化させることができる。  The first, second, fourth and fifth links 15, 16, 18 and 19 constitute a so-called pan-graph-type quadruple link mechanism, and the third link 17 is connected to the axis of symmetry. As a result, the angle between the first and second links 15 and 16 can be increased or decreased. Thereby, the interval between the drive roller shafts 10 connected to the first and second links 15 and 16 can be changed.
図 1の乗降口部 A , Eでは、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が最小 になっている。 この状態から、 駆動レール 5と補助レール 7との間の間隔を小さ くすると、 雨傘を広げるときの傘の骨組の動作と同様にリンク機構 1 4が動作し、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が大きくなる。 At the entrances A and E in FIG. 1, the distance between the drive roller shafts 10 of the adjacent steps 2 is minimized. From this state, if the distance between the drive rail 5 and the auxiliary rail 7 is reduced, the link mechanism 14 operates in the same manner as the umbrella frame when the umbrella is spread, The distance between the drive roller shafts 10 of the adjacent steps 2 becomes large.
図 1の中間傾斜部 Cでは、 駆動レール 5と補助レール 7との間の間隔が最小で あり、 隣接する踏段 2の駆動ローラ軸 1 0の間隔が最大となっている。 従って、 この領域で踏段 2の速度は最大となる。 また、 この状態では、 第 1及び第 2のリ ンク 1 5 , 1 6がほぼ一直線上に配置される。  In the middle inclined portion C in FIG. 1, the distance between the drive rail 5 and the auxiliary rail 7 is the smallest, and the distance between the drive roller shafts 10 of the adjacent steps 2 is the largest. Therefore, the speed of step 2 is maximum in this region. In this state, the first and second links 15 and 16 are arranged substantially in a straight line.
このような傾斜部高速エスカレー夕一では、 踏段 2の移動速度に同期して、 上 部移動手摺 3 6及び下部移動手摺 3 8が低速走行され、 中間移動手摺 4 0が高速 走行されるため、 移動手摺 3 6 , 3 8， 4 0の移動速度と踏段 2の移動速度との 差を抑えることができ、 踏段 2が変速した際にも移動手摺 3 6 , 3 8 , 4 0を掴 み易くすることができる。  In such an inclined high-speed escalating evening, the upper moving handrail 36 and the lower moving handrail 38 run at low speed and the intermediate moving handrail 40 runs at high speed in synchronization with the moving speed of the step 2. The difference between the moving speed of the moving handrails 36, 38, 40 and the moving speed of the step 2 can be suppressed, and the moving handrails 36, 38, 40 can be easily grasped even when the step 2 shifts. can do.
また、 上部移動手摺 3 6及び下部移動手摺 3 8の移動速度を上側乗降口部 A及 び下側乗降口部 Eにおける踏段 2の移動速度と同じにすることにより、 上側乗降 口部 A及び下側乗降口部 Eにおいて乗客が安定して乗降することができる。 さらに、 実施の形態 1では、 上部手摺装置 3 5及び下部手摺装置 3 7と中間手 摺装置 3 9との境界が、.水平部 4 1を延長した直線と中間直線部 4 2を延長した 直線との交点 F付近に位置している。 このため、 例えば図 2では、 上部移動手摺 3 6又は中間移動手摺 4 0の進行方向が変わるところで、 手摺の持ち替えを行う ことができる。 従って、 手摺の持ち替えのタイミングが取り易く、 持ち替え動作 をスムーズに行うことができる。 図 2では上曲部 Bを示したが、 下曲部 Dについ ても同様の構成をとることができる。  In addition, by making the moving speed of the upper moving handrail 36 and the lower moving handrail 38 the same as the moving speed of the step 2 at the upper entrance / exit A and the lower entrance / exit E, the upper entrance / exit A and the lower exit / exit. Passengers can get on and off the vehicle stably at the side entrance E. Further, in the first embodiment, the boundary between the upper handrail device 35 and the lower handrail device 37 and the intermediate handrail device 39 is a straight line extending the horizontal portion 41 and a straight line extending the intermediate straight portion 42. It is located near the intersection F with. For this reason, for example, in FIG. 2, the handrail can be changed when the traveling direction of the upper moving handrail 36 or the intermediate moving handrail 40 changes. Therefore, it is easy to change the handrail holding timing, and the handholding operation can be performed smoothly. Although FIG. 2 shows the upper bent portion B, the same configuration can be applied to the lower bent portion D.
なお、 上部移動手摺 3 6及び下部移動手摺 3 8の移動速度は、 上側乗降口部 A 及び下側乗降口部 Eにおける踏段 2の移動速度と完全に同じにする必要はなく、 例えば上側乗降口部 A及び下側乗降口部 Eにおける踏段 2の移動速度と中間傾斜 部 Cにおける踏段 2の移動速度との中間の速度としてもよい。 これにより、 上部 移動手摺 3 6及び下部移動手摺 3 8の移動速度と中間移動手摺 4 0の移動速度と の差を小さくすることができる。 実施の形態 2 .  Note that the moving speed of the upper moving handrail 36 and the lower moving handrail 38 does not need to be completely the same as the moving speed of the step 2 at the upper entrance / exit A and the lower entrance / exit E. The speed may be an intermediate speed between the moving speed of the step 2 in the part A and the lower entrance / exit E and the moving speed of the step 2 in the intermediate inclined part C. Thereby, the difference between the moving speed of the upper moving handrail 36 and the lower moving handrail 38 and the moving speed of the intermediate moving handrail 40 can be reduced.

このような傾斜部高速ェスカレ一ターでは、 踏段 2に加減速度が生じる上曲部 B及び下曲部 Dで手摺の持ち替えを行わずに済む。 即ち、 乗客は、 踏段 2の速度 が一定となる上側乗降口部 Aと中間傾斜部 Cとの境界付近、 或いは、 下側乗降口 部 Eと中間傾斜部 Cとの境界付近で手摺を安定して持ち替えることができる。 また、 上曲部 B及び下曲部 Dでは踏段 2と上部移動手摺 3 6との間に移動量の 差が生じることになるが、 上側乗降口部 A及び下側乗降口部 Eと中間傾斜部 Cと の間の速度比 （変速比） が 1 . 5〜2程度であれば、 上曲部 B又は下曲部 Dの範 囲内での踏段 2と上部移動手摺 3 6との間の移動量の差は 2 0 0〜3 0 0 mm程 度であり、 許容できる範囲内である。  In such a high speed escalator with a slope, it is not necessary to change the handrail at the upper curved portion B and the lower curved portion D where the acceleration / deceleration of the step 2 is generated. In other words, the passenger stabilizes the handrail near the boundary between the upper entrance / exit A and the middle inclined part C where the speed of the step 2 is constant, or near the boundary between the lower entrance / exit E and the middle inclined part C. Can be changed. Also, in the upper curved section B and the lower curved section D, a difference in the amount of movement occurs between the step 2 and the upper moving handrail 36, but the upper and lower entrances A and E have an intermediate inclination. If the speed ratio (speed change ratio) between part C and 1.5 is about 2-2, the movement between step 2 and upper handrail 36 within the range of upper curved part B or lower curved part D The difference between the quantities is on the order of 200 to 300 mm, which is within an acceptable range.
