Description

この発明は、エスカレータ、移動通路のような乗客コンベヤの非常制動装置に関するものである。   The present invention relates to an emergency braking device for passenger conveyors such as escalators and moving passages.

従来の乗客コンベアの非常制動装置では、軸は複数の軸受板を貫通する形で支持され、この軸の駆動チェーン側にレバーが配置され、反対側にラチェットポールが配置され、レバーとラチェットポールとはこの軸により連結されている。
そして、レバーはシューを介して駆動チェーン上に載るようになっており、駆動チェーンが破断したときには軸を中心にレバーが降下回動し、同時にラチェットポールも回動し、主軸に取り付けられているラチェットホイールと係合して主軸の回転を阻止し、踏み板が下方へ逸走しょうとする動作を制動するようになっている。すなわち、軸は離れた複数の軸受を貫通し回動する構造になっている。（特許文献１参照）。 In a conventional emergency braking system for passenger conveyors, a shaft is supported in a form that penetrates a plurality of bearing plates, a lever is disposed on the drive chain side of the shaft, a ratchet pole is disposed on the opposite side, and the lever, ratchet pole, Are connected by this shaft.
The lever is mounted on the drive chain via the shoe, and when the drive chain is broken, the lever is pivoted downward about the shaft, and the ratchet pole is also pivoted and attached to the main shaft. It engages with the ratchet wheel to prevent the main shaft from rotating, and brakes the movement of the tread plate trying to escape downward. That is, the shaft is configured to pass through a plurality of distant bearings and rotate. (See Patent Document 1).

実公昭６３−１６６９８号公報Japanese Utility Model Publication No. 63-16698

従来の乗客コンベアの非常制動装置では、軸は離れた複数の軸受を貫通し回動するので、スムーズな回動を得るためには、各々の軸受部貫通穴（軸受穴）の中心は精度よく一致させる必要がある。このため、軸受部の軸受板を溶接等で固定した後、軸受穴を同時加工する必要があり、治具や設備が嵩むことになる。
また、例えばレバー側のみ、軸受板の位置を可調整とすれば、軸を通した後に軸受穴同士の芯を調整できるので同時加工が不要となるが、付帯部品や関連した加工が増えコストが高くなる。
また、軸受板の軸受穴を軸径に対して大き目とし、先に穴を開けた状態で組み立てると穴の芯がずれても軸を貫通させることができるが、軸と軸受穴の隙間が大きくなり、チェーンの振動がレバーを介して軸に伝わると、軸受部でがたつき音が発生することがあるという問題点があった。 In the conventional emergency braking system for passenger conveyors, the shaft rotates through a plurality of distant bearings. Therefore, in order to obtain a smooth rotation, the center of each bearing portion through hole (bearing hole) is accurately located. Must match. For this reason, after fixing the bearing plate of a bearing part by welding etc., it is necessary to process a bearing hole simultaneously, and a jig | tool and an installation will increase.
For example, if the position of the bearing plate is adjustable only on the lever side, the cores of the bearing holes can be adjusted after passing through the shaft, so simultaneous processing is not necessary, but additional parts and related processing increase and costs increase. Get higher.
In addition, if the bearing hole of the bearing plate is large with respect to the shaft diameter and assembled with the hole drilled first, the shaft can be penetrated even if the center of the hole is displaced, but the gap between the shaft and the bearing hole is large. Thus, when the vibration of the chain is transmitted to the shaft through the lever, there is a problem that rattling noise may occur in the bearing portion.

この発明に係わる乗客コンベアの非常制動装置は、
乗客コンベヤの主枠に設けた駆動機、この駆動機の出力軸に取り付けられた駆動機側駆動鎖歯車、上記乗客コンベアの主枠に軸支された主軸に嵌合固定された主軸側駆動鎖歯車、およびこの主軸側駆動鎖歯車と上記駆動機側駆動鎖歯車間に巻き掛けられた無端状の駆動チェーンで構成された駆動装置を備えた乗客コンベアの非常制動装置において、

上記軸受け部の軸受穴を、上記連動軸の軸径より大径な穴径とし、上記軸受部に、上記軸受穴での上記連動軸のがたつきを防止する押え具（以下「押え板」という）を取り付けたものである。 An emergency braking device for a passenger conveyor according to the present invention,
A driving machine provided on the main frame of the passenger conveyor, a driving side driving chain gear attached to the output shaft of the driving machine, and a main driving side driving chain fitted and fixed to the main shaft supported by the main frame of the passenger conveyor. In an emergency braking device for a passenger conveyor comprising a gear, and a driving device composed of an endless drive chain wound between the main shaft side drive chain gear and the drive side drive chain gear,
A lever that is always engaged with the drive chain and disengaged when the drive chain is broken, and is displaced (rotating operation) for emergency braking of the passenger conveyor, and when the drive chain is broken, the lever is displaced (turned). Engaging the ratchet wheel fitted and fixed to the main shaft in a moving operation), the ratchet pole for preventing the rotation of the main shaft and emergency braking of the passenger conveyor, connecting the ratchet pole and the lever, the lever A shaft (hereinafter referred to as an “interlocking shaft”) that interlocks the ratchet pole when displaced (rotation operation), and a bearing portion that supports the interlocking shaft,
The bearing hole of the bearing portion has a diameter larger than the shaft diameter of the interlocking shaft, and a presser (hereinafter referred to as “presser plate”) that prevents the interlocking shaft from rattling in the bearing hole is formed in the bearing portion. Attached).

この発明の乗客コンベアの非常制動装置によれば、連動軸は押え板によって上下方向の移動が規制されているため、押え板を設置するだけで振動により微小に動くことによる軸受穴との当たり音の発生を防止することができる。また、連動軸の軸径と軸受穴の穴径との差を比較的大きく取ることができるので、軸受穴を加工した後に軸受板の制動装置本体への溶接が可能となるので生産性があがり、最低限の施策で振動によるがたつき音を防止できる。   According to the emergency braking device of the passenger conveyor of the present invention, since the interlocking shaft is restricted from moving in the vertical direction by the presser plate, the contact sound with the bearing hole due to the minute movement due to vibration just by installing the presser plate. Can be prevented. In addition, since the difference between the shaft diameter of the interlocking shaft and the hole diameter of the bearing hole can be made relatively large, the bearing plate can be welded to the brake device body after the bearing hole has been processed, which increases productivity. With a minimum measure, rattling noise caused by vibration can be prevented.

図１〜４において、実施の形態１における駆動装置は、次の部材で構成されている。
すなわち、この駆動装置は、乗客コンベアの主枠１に軸支された主軸２、乗客コンベヤの主枠１に設けた駆動機３、この駆動機３の出力軸に取り付けられた駆動機側駆動鎖歯車３ａ、主軸２に嵌合固定された主軸側駆動鎖歯車５、この主軸側駆動鎖歯車と駆動機側駆動鎖歯車３ａ間に巻き掛けられた無端状の駆動チェーン４および主軸２に嵌合固定された踏板鎖車７などで構成されている。
上記の構成において、主軸２は、駆動機３の駆動鎖歯車３ａ、駆動チェーン４および主軸の駆動鎖歯車５を介して伝達される動力によって回転し、踏板鎖車７およびこの踏板鎖車に巻き掛られた無端状の踏板鎖９を介して、無端状に連結された踏板８を循環移動（走行）させる。なお、図２では、踏板鎖車７、踏板８、踏板鎖９などは図示していない。 1-4, the drive device in Embodiment 1 is composed of the following members.
That is, the driving device includes a main shaft 2 that is pivotally supported on the main frame 1 of the passenger conveyor, a driving device 3 that is provided on the main frame 1 of the passenger conveyor, and a driving device side driving chain that is attached to the output shaft of the driving device 3. The gear 3a, the main shaft side drive chain gear 5 fitted and fixed to the main shaft 2, and the endless drive chain 4 and the main shaft 2 wound between the main shaft side drive chain gear and the drive side drive chain gear 3a It consists of a fixed treadmill 7 and the like.
In the above configuration, the main shaft 2 is rotated by the power transmitted through the drive chain gear 3a, the drive chain 4 of the drive machine 3 and the drive chain gear 5 of the main shaft, and is wound around the treadle chain wheel 7 and the treadle chain wheel. The endlessly connected treads 8 are circulated and moved (traveled) via the endless treadle chains 9 that are hung. In FIG. 2, the treadle chain wheel 7, the treadboard 8, the treadle chain 9 and the like are not shown.

次に、図１〜４にもとづき実施の形態１における非常制動装置について説明する。
この非常制動装置は、次の部材で構成されている。
すなわち、この非常制動装置は、主軸２の一端部に嵌合固定されたラチェットホイール（爪車）６、駆動チェーン４側の、後述する連動軸１３の軸端に嵌合固定され、駆動チェーン４の破断時に回動して破断状況を検知するレバー１１、駆動チェーン４の反対側の、後述する連動軸１３の軸端に嵌合固定され、主軸２のラチェットホイール６の爪６ａに係合して主軸２の回転を阻止するラチェットポール１２、制動装置本体１４に取り付けられた複数の軸受板１６ａ、１６ｂ、１６ｃからなる軸受部１５、軸受板１６ａ、１６ｂ、１６ｃの各軸受穴１７ａを貫通して支持され、レバー１１とラチェットポール１２とを連動するよう一体に連結する連動軸１３、この連動軸のがたつきを防止する押え板２０などで構成されている。
ここで、各軸受穴１７ａの穴径は、連動軸１３が挿通し易いよう大径、すなわち軸１３の軸径に比べて若干大き目に設定し、軸径に対して余裕を持たせてあるので、隙間１８が存在する。このため、ラチェットポール６側およびレバー１１側の軸受板１６ｂ、１６ｃには、押え板２０がボルト１９で取り付けられ、その接触端面２０ａを連動軸１３上に軽く接触させることにより上記の隙間１８を塞ぎ連動軸１３のがたつきを防いでいる。 Next, the emergency braking device in Embodiment 1 is demonstrated based on FIGS.
This emergency braking device is composed of the following members.
That is, the emergency braking device is fitted and fixed to a ratchet wheel (claw wheel) 6 fitted and fixed to one end of the main shaft 2 and the shaft end of the interlocking shaft 13 described later on the drive chain 4 side. The lever 11 that rotates at the time of breakage and detects the breakage state is fitted and fixed to the shaft end of the interlocking shaft 13 that will be described later on the opposite side of the drive chain 4, and engages with the claw 6 a of the ratchet wheel 6 of the main shaft 2. Through the ratchet pole 12 for preventing the rotation of the main shaft 2, the bearing portion 15 comprising a plurality of bearing plates 16a, 16b, 16c attached to the braking device body 14, and the bearing holes 17a of the bearing plates 16a, 16b, 16c. The interlocking shaft 13 is integrally supported so that the lever 11 and the ratchet pole 12 are interlocked, and the presser plate 20 prevents the interlocking shaft from rattling.
Here, the diameter of each bearing hole 17a is set to a large diameter so that the interlocking shaft 13 can be easily inserted, that is, slightly larger than the shaft diameter of the shaft 13, and a margin is provided for the shaft diameter. , There is a gap 18. For this reason, the holding plate 20 is attached to the bearing plates 16b and 16c on the ratchet pole 6 side and the lever 11 side with bolts 19, and the contact end surface 20a is lightly brought into contact with the interlocking shaft 13 so that the gap 18 is formed. Shaking of the closing interlocking shaft 13 is prevented.

次に非常制動装置の作動について説明する。
通常運転時、連動軸１３は、軸受板６ａ、１６ｂ、１６ｃに対して回動可能であるが、レバー１１がシュー１１ａを介して駆動チェーン４上に載っているので通常は回動しない。
駆動チェーン４が破断した時などの非常時に、レバー１１が実線状態から鎖線状態（変位）になって連動軸１３が回動すると、ラチェットポール１２も回動してラチェットホイール６の爪６ａと噛み合い、この噛み合いによってラチェットホイール６を停止する。ラチェットホイール６が停止すると主軸２などと共に踏板鎖車７も停止し乗客荷重などによって踏板８が下方へ移動するのを阻止し、乗客コンベアを非常制動する。 Next, the operation of the emergency braking device will be described.
During normal operation, the interlocking shaft 13 can rotate with respect to the bearing plates 6a, 16b, and 16c, but normally does not rotate because the lever 11 is placed on the drive chain 4 via the shoe 11a.
In an emergency such as when the drive chain 4 is broken, when the lever 11 changes from a solid line state to a chain line state (displacement) and the interlocking shaft 13 rotates, the ratchet pole 12 also rotates and meshes with the claw 6a of the ratchet wheel 6. The ratchet wheel 6 is stopped by this engagement. When the ratchet wheel 6 is stopped, the tread plate chain 7 is also stopped together with the main shaft 2 and the like so that the tread plate 8 is prevented from moving downward due to the passenger load or the like, and the passenger conveyor is emergency braked.

非常制動装置が作動しない通常の運転時には、以下のように作動する。
乗客コンベアが運転されると、乗客の増減により駆動チェーン４の張力も変化する。ある張力条件で駆動チェーン４が共振して振れが生じると駆動チェーン４上に載っているシュー１１aも共に振動する。この振動がレバー１１を介して連動軸１３に伝達されるが、
連動軸１３は、押え板２０によって上下方向の移動が規制されているため、振動により微小に動くことにより生じる軸受穴１７aとの当たり音の発生は、阻止される。 During normal operation when the emergency braking device does not operate, the system operates as follows.
When the passenger conveyor is operated, the tension of the drive chain 4 also changes due to increase or decrease of passengers. When the drive chain 4 resonates under certain tension conditions and a vibration occurs, the shoe 11a mounted on the drive chain 4 also vibrates together. This vibration is transmitted to the interlocking shaft 13 via the lever 11,
Since the movement of the interlocking shaft 13 in the vertical direction is restricted by the presser plate 20, generation of a hitting sound with the bearing hole 17 a caused by a slight movement due to vibration is prevented.

このように、押え板２０によって連動軸１３の軸受穴１７aとの当たり音の発生を防止できるので、連動軸１３の軸径と軸受穴１７aの穴径との差を比較的大きく取ることができ、軸受穴１７aを加工した後に軸受板１６ａ、１６ｂ、１６ｃの制動装置本体１４への溶接が可能となり生産性がよくなる。また、押え板２０を設置するだけで、連動軸１３のがたつきによる音の発生を防止することができる。
連動軸１３と軸受部１５の隙間１８を大きくとれば、軸受穴１７ａ中心の芯ずれの許容範囲も大きくできるので生産性が向上し、しかも、上記したように、軸受穴１７aに緩く挿通した連動軸１３による、がたつき音発生の不具合を未然に防止できる。
また、連動軸１３のがたつきは、主にレバー１１側の軸受部で発生しやすいので、押え板２０の設置は、レバー１１側（矢印Ｂ側）の軸受板１６ｃ付近の一箇所に設置するのみでも十分に効果があり、その場合、最小限の押え箇所ですみ部品点数を削減できるのでコストも更に削減することができる。 As described above, since the press plate 20 can prevent the hitting sound with the bearing hole 17a of the interlocking shaft 13, the difference between the shaft diameter of the interlocking shaft 13 and the hole diameter of the bearing hole 17a can be made relatively large. The bearing plates 16a, 16b, and 16c can be welded to the brake device main body 14 after the bearing hole 17a is processed, and the productivity is improved. Moreover, generation of sound due to rattling of the interlocking shaft 13 can be prevented only by installing the presser plate 20.
If the clearance 18 between the interlocking shaft 13 and the bearing portion 15 is increased, the tolerance of misalignment at the center of the bearing hole 17a can be increased, so that the productivity is improved, and as described above, the interlock that is loosely inserted into the bearing hole 17a. The problem of rattling noise caused by the shaft 13 can be prevented in advance.
Further, rattling of the interlocking shaft 13 is likely to occur mainly in the bearing portion on the lever 11 side, so that the presser plate 20 is installed at one location near the bearing plate 16c on the lever 11 side (arrow B side). Even if it does, it is effective enough. In that case, the number of parts can be reduced with a minimum amount of pressing parts, and the cost can be further reduced.

図５に示す押え板２０は、その接触端面２０aが連動軸１３の形状に沿った円弧状になっている。その他は実施の形態１と同一構成である。
このように構成した場合も実施の形態１と同様の効果が得られると共に押え板２０と連動軸１３との接触長さが長くなるため、接触面圧を低下（軸との接触部の面圧が小さくなる）でき、連動軸１３の微小な回動による、経年的な磨耗に対して有利となる効果がある。 Embodiment 2. FIG.
FIG. 5 is a front view of the presser plate 20 according to Embodiment 2 of the present invention.
The presser plate 20 shown in FIG. 5 has a contact end surface 20 a in an arc shape along the shape of the interlocking shaft 13. The other configuration is the same as that of the first embodiment.
Even when configured in this manner, the same effect as in the first embodiment can be obtained and the contact length between the presser plate 20 and the interlocking shaft 13 is increased, so that the contact surface pressure is reduced (the surface pressure of the contact portion with the shaft). This is advantageous in that it is advantageous to wear over time due to the minute rotation of the interlocking shaft 13.

図６は、この発明の実施の形態３における押え板２０の正面図で、ボルト１９を挿通する押え板２０の取付部２１は、取り付け位置を例えば上下に位置調整できるよう長穴状となっている。その他は実施の形態１と同一構成である。
このように構成した場合も実施の形態１と同様の効果が得られると共に連動軸１３の微小な回動により経年的に軸受穴１７ａの下面や押え板の接触端面２０aが磨耗した場合でも当接部分の調整が可能となる。すなわち、経年的な磨耗で隙間が拡大しても再調整が可能となる。 Embodiment 3 FIG.

Yes. The other configuration is the same as that of the first embodiment.
Even in such a configuration, the same effect as in the first embodiment can be obtained, and even when the lower surface of the bearing hole 17a and the contact end surface 20a of the presser plate are worn over time due to the minute rotation of the interlocking shaft 13, contact is made. Adjustment of the part becomes possible. That is, readjustment is possible even if the gap increases due to wear over time.
