Description

この発明は、エレベータの戸開中に制御系の不具合、電気接点の異常、巻上機ブレーキの不具合等により、かごが走行した場合に機械的にかごの走行を阻止するエレベータの出発阻止装置に関するものである。 The present invention relates to an elevator start prevention device that mechanically prevents a car from traveling when the car travels due to a malfunction of a control system, an abnormality of an electrical contact, a malfunction of a hoisting machine brake or the like while the elevator door is open. Is.

近年、エレベータは電子制御により、滑らかに最適の運転動作が得られるように予めプログラム化されている。しかし、あらゆる状態を想定してプログラム化されている筈であるが、プログラムバグ等があって異常運転することも全く考えられない訳ではない。また、巻上機のブレーキ面に油が滲みて、制動力が確保できないこともある。また、電気接点に塵埃が付着して誤動作する恐れもあった。 In recent years, elevators have been programmed in advance so that an optimum driving operation can be smoothly obtained by electronic control. However, although it should have been programmed for all situations, it is not entirely impossible to operate abnormally due to program bugs. Moreover, oil may ooze on the brake surface of the hoisting machine, and the braking force may not be ensured. In addition, there is a risk of malfunction due to dust adhering to the electrical contacts.

また、従来技術として、電気的に乗場の戸が閉まったことを接点スイッチで確認してエレベータを走行させるもの (例えば、特許文献１参照)、巻上機のブレーキによりかごが停止階より動かないように保持するもの（例えば、特許文献２参照）、戸閉装置の駆動リンクの最初の動きを利用してかごの係合装置のベーンを広げ、乗場のドライブローラにがたつかないように密着させて係合して戸開閉力を伝達するもの（例えば、特許文献３参照）が知られている。 Further, as a conventional technique, an elevator is driven by confirming that a landing door is electrically closed with a contact switch (see, for example, Patent Document 1), and a car does not move from a stop floor by a hoisting machine brake. (See, for example, Patent Document 2), the vane of the car engagement device is widened using the initial movement of the drive link of the door closing device, so that it does not rattle against the drive roller of the landing A device that engages and transmits door opening / closing force is known (for example, see Patent Document 3).

従来の特許文献１記載のものでは、電気接点に塵埃の付着があると接点不良が起こり、戸が閉まっていないのに戸が閉まったと認識してエレベータを走行させる恐れがある。また、特許文献２記載のものでは、巻上機のブレーキ面に油の付着があると、規定のブレーキ保持力が出ないため、エレベータがずれ動くという問題がある。エレベータ戸開中にこのような異常が起こると、戸開したままエレベータが走行する恐れがある。 In the conventional one described in Patent Document 1, if there is dust attached to the electrical contact, a contact failure may occur, and the elevator may travel by recognizing that the door is closed even though the door is not closed. Moreover, in the thing of patent document 2, when there is oil adhesion to the brake surface of a hoisting machine, since a regular brake holding force does not come out, there exists a problem that an elevator moves. If such an abnormality occurs while the elevator door is open, the elevator may run with the door open.

この発明は、上述のような課題を解決するためになされたもので、エレベータ走行中は収納状態にある出発阻止板を、乗場に到着したら戸開動作中から戸閉動作中まで間の戸開状態では突出させておき、異常が起きて戸開状態のまま走行しても出発を阻止できるようにしたエレベータの出発阻止装置を提供するものである。 The present invention has been made to solve the above-described problems. When the elevator starts, the departure blocking plate that is in the stowed state is opened between the door opening operation and the door closing operation when arriving at the landing. The present invention provides an elevator departure prevention device that protrudes in a state and can prevent departure even when an abnormality occurs and the vehicle is left open.

この発明に係るエレベータの出発阻止装置においては、かごの戸の乗場側に突出可能に設けられ、かごの走行中はかごの戸側に引き込まれた収納位置にある出発阻止手段を備え、かごが乗場に到着し戸開動作開始から戸閉動作中までの戸開状態では、出発阻止手段を収納位置から乗場側に突出させて、一部が投影面上で乗場構成部品に重なる位置となるようにしたものである。 In the elevator departure prevention apparatus according to the present invention, the elevator departure prevention device is provided so as to be able to project to the landing side of the car door, and includes a departure prevention means in a stowed position retracted to the car door side while the car is running. In the door open state from the start of the door opening operation to the door closing operation after arrival at the landing, the departure prevention means protrudes from the storage position to the landing side so that a part overlaps the landing component on the projection plane. It is a thing.

また、この発明に係るエレベータの出発阻止装置においては、かごの戸の乗場側に突出可能に設けられ、かごの走行中はかごの戸側に引き込まれた収納位置にあり、かごが乗場に到着し戸開動作開始から戸閉動作中までの戸開状態では、収納位置から乗場側に突出して、一部が投影面上で乗場構成部品に重なる位置となる出発阻止手段と、エレベータが保守運転又は消防運転に切り替えられた時に動作して、出発阻止手段を解除して収納位置に抑えておく解除手段とを備えたものである。 Further, in the elevator departure prevention apparatus according to the present invention, the elevator departure preventing device is provided so as to be able to protrude to the landing side of the car door, and is in a storage position drawn into the car door side while the car is running, so that the car arrives at the landing. In the door open state from the start of the door opening operation to the door closing operation, departure prevention means that protrudes from the storage position to the landing side and partially overlaps the landing component on the projection surface, and the elevator performs maintenance operation Alternatively, it is provided with release means that operates when the operation is switched to the firefighting operation and releases the departure prevention means to keep it at the storage position.

この発明によれば、戸開動作中にエレベータに異常が発生し、エレベータが戸を開いたまま走行してしまうことによる２次事故を機械的に確実に阻止することができる効果がある。 According to this invention, an abnormality occurs in the elevator during the door opening operation, and it is possible to mechanically reliably prevent a secondary accident caused by the elevator traveling with the door open.

上記のように構成されたエレベータの出発阻止装置の動作について説明する。
エレベータかご１が目的階に到着すると、戸開動作を開始する。戸開力がドアー駆動モータ６を通じて働くと戸駆動用リンク３ｃの最初の動きでベーン角度変更リンク３ａは、可動ベーン１０ｂの角度を広げる。この時、可動ベーン１０ｂの背面の第１のリンク１０ｃ、第２のリンク１１、第３のリンク２０ａへと動きが伝達され、図６、図７に示すように、出発阻止板２０が連動して開き、乗場の戸９の方向に開きながら突出し、その一部が投影面上で乗場構成部品に重なる位置となる。なお、出発阻止板２０が乗場の戸９側に突出してもかごの戸７が開閉する水平方向の動きには妨げにはならない。
そして、戸開動作しつつある時或いは戸閉動作中であっても戸閉が完了していない時、万一エレベータの異常でかご１に走行指令が誤って出され、エレベータが走行し始めて、例えばかご１が上昇方向に走行すると、出発阻止板２０の上端部が乗場戸閉装置１６のハンガーケース部材１７の下端部に当たって阻止されるため、かご１はそれ以上走行できなくなる。また、かご１が下降方向に走行すると、出発阻止板２０の下端部が乗場敷居１３に当たって阻止されるため、かご１はそれ以上走行できなくなる。なお、この際、出発阻止板２０が破壊される恐れも懸念されるが、エレベータが走行し始めた時での阻止であり、慣性力も比較的小さいので、問題はない。
また、エレベータ走行中は、かごの戸閉装置は戸閉状態にある。この時、戸閉力がドアー駆動モータ６を通じて働いており、可動ベーン１０ｂを軸１０ｄで軸支させ、戻しばね２６により可動ベーン１０ｂを常に時計方向へ引き寄せられる。そして、可動ベーン１０ｂの背面の第１のリンク１０ｃの先端に軸１１ａにより接合した第２のリンク１１と、出発阻止板２０の背面の第３のリンク２０ａを軸１１ｂで接合している。したがって、かごの戸閉装置が閉状態の時は、可動ベーン１０ｂの動きと連動して、図２、図３に示すように、出発阻止板２０は閉じられ、かごの戸７の方向に畳まれて収納された状態となるので、出発阻止板２０がかご１の走行の邪魔になることはない。 The operation of the elevator departure prevention apparatus configured as described above will be described.
When the elevator car 1 arrives at the destination floor, the door opening operation is started. When the door opening force is applied through the door drive motor 6, the vane angle changing link 3a widens the angle of the movable vane 10b by the initial movement of the door drive link 3c. At this time, the movement is transmitted to the first link 10c, the second link 11, and the third link 20a on the back surface of the movable vane 10b, and as shown in FIG. 6 and FIG. It opens and protrudes while opening in the direction of the door 9 of the hall, and a part thereof is located on the projection plane so as to overlap the hall component. Note that even if the departure blocking plate 20 protrudes toward the landing door 9 side, it does not hinder the horizontal movement of the car door 7 opening and closing.
And when the door opening operation is being performed or when the door closing operation is not completed, if the elevator is abnormal, a traveling command is erroneously issued to the car 1, and the elevator starts to travel, For example, when the car 1 travels in the upward direction, the upper end portion of the departure prevention plate 20 hits the lower end portion of the hanger case member 17 of the landing door closing device 16 and is prevented, so that the car 1 cannot travel further. Further, when the car 1 travels in the descending direction, the lower end portion of the departure prevention plate 20 hits the landing threshold 13 and is blocked, so that the car 1 cannot travel any more. At this time, there is a concern that the departure prevention plate 20 may be destroyed, but this is a prevention when the elevator starts to travel, and there is no problem because the inertial force is relatively small.
Further, the car door closing device is in the door closed state during the elevator traveling. At this time, the door closing force is applied through the door drive motor 6, the movable vane 10b is pivotally supported by the shaft 10d, and the movable vane 10b is always drawn clockwise by the return spring 26. And the 2nd link 11 joined to the front-end | tip of the 1st link 10c of the back surface of the movable vane 10b by the axis | shaft 11a, and the 3rd link 20a of the back surface of the starting prevention board 20 are joined by the axis | shaft 11b. Therefore, when the car door closing device is in the closed state, the start blocking plate 20 is closed in conjunction with the movement of the movable vane 10b, and is folded in the direction of the car door 7, as shown in FIGS. Since it is rarely stored, the departure prevention plate 20 does not interfere with the traveling of the car 1.

以上のように、実施の形態１によれば、戸開動作中にエレベータに異常が発生し、エレベータが戸を開いたまま走行してしまうことによる２次事故を機械的に確実に阻止することができる。 As described above, according to the first embodiment, it is possible to mechanically reliably prevent a secondary accident caused when an abnormality occurs in the elevator during the door opening operation and the elevator travels with the door open. Can do.

上記実施の形態１では、出発阻止装置が働いていると、保守作業時に戸を開いたまま保守運転することができず、また消防運転付きのエレベータにおいては、消防夫による専用運転で戸を開いたまま運転することができないという問題があるが、この実施の形態２においては、保守作業時及び消防運転時に戸を開いたままエレベータを走行できるように出発阻止装置の解除装置を設けたものである。
図において、２４はかごの戸７の上方に位置するように戸閉装置桁５ａの前面に設けられた解除装置の隔て板、２４ａ、２４ｂは隔て板２４の両端部を支持するリンク、２４ｃは戸閉装置桁５ａの前面両端部に固定された軸受、２４ｄは戸閉装置桁５ａの一端部前面の軸受２４ｃの外側に固定された取付金、２４ｅは取付金２４ｄに設けられたピン、２５は取付金２４ｄにピン２４ｅにより揺動自在に軸支されて取り付けられた隔て板２４を駆動する駆動モータ、２５ａは駆動モータ２５のねじ棒軸、２４ｆはねじ棒軸２５ａにねじ込まれた首振りナット、２５ｂは首振りナット２４ｆの先端部に設けられたピン、２５ｃはリンク２４ｂの両端を軸支するピン、２７はばね、２８、２９は出発阻止板２０に設けられたストッパーで、回動範囲を規制する。３０、３１は出発阻止板２０に設けられたばね受で、このばね受の間にばね２７が装着されている。 In Embodiment 1 described above, when the departure prevention device is working, maintenance operation cannot be performed with the door open during maintenance work, and in an elevator with fire fighting operation, the door is opened by a fire engineer dedicated operation. However, in the second embodiment, a release blocking device is provided so that the elevator can be run with the door open during maintenance work and fire fighting operation. is there.
In the figure, 24 is a separating plate of the release device provided on the front face of the door closing device girder 5a so as to be positioned above the door 7 of the car, 24a and 24b are links that support both ends of the separating plate 24, and 24c is Bearings fixed to both ends of the front face of the door-closing device girder 5a, 24d is a mounting metal fixed to the outside of the bearing 24c on the front surface of one end of the door-closing device girder 5a, 24e is a pin provided on the mounting metal 24d, 25 Is a drive motor for driving a separation plate 24 that is pivotally supported by a mounting metal 24d by a pin 24e, 25a is a screw rod shaft of the drive motor 25, and 24f is a swinging screwed into the screw rod shaft 25a. Nut, 25b is a pin provided at the tip of the swing nut 24f, 25c is a pin that pivotally supports both ends of the link 24b, 27 is a spring, 28 and 29 are stoppers provided on the starting prevention plate 20, range To regulate. 30 and 31 are spring supports provided on the starting prevention plate 20, and a spring 27 is mounted between the spring supports.

エレベータの制御において、保守運転又は消防運転（火災時に消防夫がエレベータの戸を開いたまま運転する機能）に切り替えられると、自動的に隔て板２４の駆動モータ２５が回転し、隔て板２４を支持しているリンク２４ｂの首振りナット２４ｆが引き寄せられ、リンク２４ａ、２４ｂの働きにより、隔て板２４がかご奥行き方向へ平行移動する。このため、戸開中であれば、出発阻止板２０は、図１１の状態から、出発阻止板２０の通し軸２２の上端部に設けられた腕２３のピン２３ａが隔て板２４により抑えられ、出発阻止板２０が図１３に示すように、第２のリンク１１の位置に関係なく、出発阻止板２０のばね力を抑え出発阻止板２０を閉じる（収納する）。このため、戸開状態のままエレベータを走行させることが可能となる。隔て板２４は出入口の戸開閉長さより長めに形成されているので、戸開位置全体で出発阻止板２０の動きを抑えることができる。
また、保守運転又は消防運転に切り替えた時、図１２に示すように、出発阻止板２０が閉じている状態であれば、隔て板２４がかご奥行き方向へ平行移動して、出発阻止板２０がそれ以上突出することがないように抑える。 In the control of the elevator, when the operation is switched to maintenance operation or firefighting operation (function in which the firefighter operates with the elevator door open in the event of a fire), the drive motor 25 of the separation plate 24 automatically rotates, and the separation plate 24 is The swing nut 24f of the supporting link 24b is attracted, and the partition plate 24 is translated in the car depth direction by the action of the links 24a and 24b. For this reason, when the door is open, the starting blocking plate 20 is suppressed from the state of FIG. 11 by the plate 24 with the pin 23a of the arm 23 provided on the upper end portion of the through shaft 22 of the starting blocking plate 20 being separated. As shown in FIG. 13, regardless of the position of the second link 11, the start blocking plate 20 suppresses the spring force of the start blocking plate 20 and closes (stores) the start blocking plate 20. For this reason, it becomes possible to drive an elevator with the door open. Since the partition plate 24 is formed longer than the door opening / closing length of the doorway, the movement of the start blocking plate 20 can be suppressed in the entire door opening position.
Further, when switching to the maintenance operation or the fire fighting operation, as shown in FIG. 12, if the departure prevention plate 20 is in a closed state, the separation plate 24 is translated in the car depth direction, and the departure prevention plate 20 is Keep it so that it no longer protrudes.

以上のように、実施の形態２によれば、保守作業時又は消防運転時に戸開状態のままでエレベータを走行させることができるので、保守作業時や消防運転時にも支障なく対応することが可能となる。 As described above, according to the second embodiment, the elevator can be run with the door open at the time of maintenance work or firefighting operation, so that it can be handled without any trouble at the time of maintenance work or firefighting operation. It becomes.

When a collision occurs with the hanger case member 17 or the landing threshold 13 of the landing door closing device 16, the collision is detected by the seat switch 32c of the departure prevention plate 20, and the power to the elevator hoist motor is forcibly turned off. A control circuit is configured.

これにより、機械的に確実に止めることに加え、電気的にも巻上機を止めるため安全性をより高めることができる。また、シートスイッチ表面の軟質材により、出発阻止板が衝突した時の金属音を抑えることができ、乗客を驚かせるようなことがない。 Accordingly, in addition to mechanically stopping the hoisting machine, the hoisting machine is electrically stopped, so that safety can be further improved. In addition, the soft material on the surface of the seat switch can suppress the metal sound when the departure prevention plate collides, and does not surprise the passenger.

FIG. 17 is a perspective view showing a main part of an elevator starting prevention device according to Embodiment 4 of the present invention, FIG. 18 is a perspective view showing a structure of a starting prevention plate using a spring type shock absorber, and FIG. FIG. 20 is a cross-sectional view taken along line B, FIG. 20 is a perspective view showing a configuration of a starting blocking plate using a rubber shock absorber, and FIG. 21 is a cross-sectional view taken along line CC in FIG. In the figure, the same or corresponding parts as those of the first and third embodiments are denoted by the same reference numerals and the description thereof is omitted.

この実施の形態４は、待ち時間や到着時間を短くするため、ランディングオープン（エレベータが階に到着する少し前に戸を開き始める機能）が付いたエレベータに適用した場合の例を示すものである。
図において、３２は出発阻止板、３２ａは出発阻止板３２の上下端部の外側に摺動可能に嵌合された外殻、３２ｂは出発阻止板３２の上下端部平坦面と外殻３２ａの内面との間に設けられた緩衝ばね、３２ｃは外殻３２ａの外表面に貼り付けられたシートスイッチで、軟質材シートを表面に貼り付けている。３２ｄは出発阻止板３２の上下端部平坦面と外殻３２ａの内面との間に設けられた緩衝ゴムである。 The fourth embodiment shows an example in which the present invention is applied to an elevator with a landing open (a function of opening a door slightly before the elevator arrives on the floor) in order to shorten waiting time and arrival time. .
In the figure, 32 is a start blocking plate, 32a is an outer shell slidably fitted to the outside of the upper and lower ends of the start blocking plate 32, and 32b is a flat surface of the upper and lower ends of the start blocking plate 32 and the outer shell 32a. A buffer spring 32c provided between the inner surface and the inner surface is a sheet switch attached to the outer surface of the outer shell 32a, and a soft material sheet is attached to the surface. Reference numeral 32d denotes a buffer rubber provided between the flat surfaces of the upper and lower ends of the start blocking plate 32 and the inner surface of the outer shell 32a.

ランディングオープン機能が付いたエレベータの着床タイミングは、着床誤差を考慮して階に到着する２５０ｍｍ程手前であり、係合ベーンの長さは着床誤差と余裕を見込み７００ｍｍ程となっている。したがって、出発阻止板の長さは、出入口有効高さ（例として、出入口高さ２１００ｍｍの場合）２１００−２５０ｍｍ×２＋余裕を見込んだ長さとして、約１５００ｍｍとすれば良く、これを戸の中央高さに取り付ける。但し、この場合にかごが異常走行した時は、エレベータの慣性力が大きくなるので、出発阻止板を衝突に耐えられるように、出発阻止板の衝突部分に衝撃を吸収するばね式緩衝装置又はゴム式緩衝装置を取り付ける。
緩衝装置は、出発阻止板の上下端に出発阻止板３２に摺動可能に外殻３２ａを形成し、衝突面に軟質材シートを表面に貼り付けたシートスイッチ３２ｃを接着し、内部に緩衝ばね３２ｂ又は緩衝ゴム３２ｄを備えたものである。
これにより、エレベータが戸開異常のまま走行しても、出発阻止板の衝突時の衝撃を緩和して止めることができる。
なお、上記緩衝装置は、ランディングオープン機能が付いたエレベータに適用したが、実施の形態１に示すような一般用のエレベータに緩衝装置を適用しても良いことは勿論である。 The landing timing of the elevator with the landing open function is about 250 mm before arrival at the floor in consideration of the landing error, and the length of the engaging vane is about 700 mm with the possibility of landing error and margin. . Therefore, the length of the start blocking plate may be about 1500 mm as the effective height of the entrance and exit (for example, when the entrance height is 2100 mm) 2100-250 mm × 2 + allowance, and this is the center of the door. Attach to height. However, if the car runs abnormally in this case, the inertial force of the elevator will increase, so that the shock absorber or rubber that absorbs the impact on the collision part of the starting blocking plate will be able to withstand the collision. Install a shock absorber.
The shock absorber has outer shells 32a formed on the upper and lower ends of the start blocking plate so as to be slidable on the start blocking plate 32, a sheet switch 32c having a soft material sheet attached to the collision surface, and a buffer spring inside. 32b or buffer rubber 32d.
As a result, even when the elevator travels with the door open abnormally, it is possible to mitigate and stop the impact at the time of collision of the departure prevention plate.
In addition, although the said buffering device was applied to the elevator with the landing open function, it is needless to say that a buffering device may be applied to the general elevator as shown in Embodiment 1. FIG.

以上説明したこの発明の出発阻止装置は、既存のエレベータへも簡単な装置を追加するだけで電気接点の接点不良や制御プログラムミスや巻上機ブレーキ面の油滲みなどによるかごに異常走行による２次事故を簡単な装置で確実に防止することができる。 The above-described start prevention device according to the present invention can be obtained by adding a simple device to an existing elevator, which is caused by abnormal running in a car due to a contact failure of an electric contact, a control program error, oil bleeding on a hoisting machine brake surface, or the like. The next accident can be reliably prevented with a simple device.

以上実施の形態では、２枚戸片開き戸について説明したが、２枚戸中央開き戸、３枚戸片開き戸、４枚戸中央開き戸にも同様に適用することができる。 Although the two-door single swing door has been described in the above embodiment, the present invention can be similarly applied to a two-door central swing door, a three-door single swing door, and a four-door central swing door.
