Description
本発明は、エレベータ管制運転用の変位感知器に係わり、特に、地震又は強風時に発生する建屋残留変位発生に対応する変位感知器の感知プレートに関する。 The present invention relates to a displacement sensor for elevator control operation, and more particularly to a sensing plate for a displacement sensor corresponding to the occurrence of residual building displacement that occurs during an earthquake or strong wind.
免震建築物の免震装置を介在した下層建築部と上層建築部の間に設けられた変位感知器の従来技術として、例えば特許文献１には、強風又は地震時（以降、強風時と称する）の建屋変位量を検出するため、免震装置の上層建築部に変位感知器の検知本体部を取り付け、免震装置の下層建築部に円環状のリングを取付ける構造が開示されている。この特許文献１によると、円環状のリング内に検知本体部のワイヤが挿通されており、建築部の水平方向変位量が許容範囲を超えると、ワイヤがリングにその変位を阻止されて許容範囲超過の検知を出力するようになっている。 As a conventional technique of a displacement sensor provided between a lower-layer building part and an upper-layer building part with a seismic isolation device for a base-isolated building, for example, Patent Document 1 discloses a strong wind or an earthquake (hereinafter referred to as a strong wind). In order to detect the amount of building displacement, a structure in which a detection main body of a displacement sensor is attached to the upper building part of the seismic isolation device and an annular ring is attached to the lower building part of the seismic isolation device is disclosed. According to this patent document 1, the wire of the detection main body portion is inserted into an annular ring, and if the amount of horizontal displacement of the building portion exceeds the allowable range, the wire is prevented from being displaced by the ring. The detection of excess is output.
また、変位感知器の他の従来技術として、図４に示す構造の変位感知器が提案されている。これによると、変位感知器７は変位感知器本体８と感知プレート１０を備え、変位感知器本体８は感知レバー９を有して上層建築部に設置され、感知プレート１０は下ブラケット１２を介して下層建築部に設置されている。そして、感知プレート１０には円形穴開き開口部１１が形成され、変位感知器７の初期セット時に円形開口部１１の中央部に変位感知器本体８の感知レバー９を挿通させている。 As another conventional displacement sensor, a displacement sensor having a structure shown in FIG. 4 has been proposed. According to this, the displacement sensor 7 includes a displacement sensor body 8 and a sensing plate 10, the displacement sensor body 8 has a sensing lever 9 and is installed in an upper building part, and the sensing plate 10 is interposed via a lower bracket 12. It is installed in the lower-level building department. A circular perforated opening 11 is formed in the sensing plate 10, and the sensing lever 9 of the displacement sensor main body 8 is inserted into the center of the circular opening 11 when the displacement sensor 7 is initially set.
そして、上記の特許文献１を含めた図４に示す従来技術の変位感知器は、強風時に建物が変位した際、感知レバー９と感知プレート１０が接触し、強風時にエレベータ管制運転（例えば、規定速度で稼働中のエレベータを低速運転にする）をＯＮ状態にする役割を果たしている。 The prior art displacement sensor shown in FIG. 4 including the above-mentioned Patent Document 1 makes contact with the sensing lever 9 and the sensing plate 10 when the building is displaced during a strong wind, and the elevator control operation (for example, specified regulation) during the strong wind. It is playing a role of turning on an elevator operating at a low speed).
ところで、図４に示す従来技術の変位感知器７は、感知レバー９が感知プレート１０の円形開口部１１の中央に初期配置された構成となっている。建屋に地震や強風などの影響で残留変位が発生した場合、感知プレート１０の中央部から建屋の残留変位量分だけ、強風時管制運転用の変位感知器の位置がずれてしまい、それ以降適切な強風時の管制運転を行えないという課題が生じる。また、残留変位量の大きさによっては常に強風時管制運転用変位感知器７の感知レバー９と感知プレート１０が接触している状態になり強風時管制運転がＯＮ状態のままになってしまう虞れがある。 By the way, the displacement sensor 7 of the prior art shown in FIG. 4 has a configuration in which the sensing lever 9 is initially arranged at the center of the circular opening 11 of the sensing plate 10. When residual displacement occurs in the building due to an earthquake or strong wind, the position of the displacement sensor for control operation during strong winds will deviate from the center of the sensing plate 10 by the amount of residual displacement of the building. There arises a problem that the control operation cannot be performed in a strong wind. Further, depending on the amount of residual displacement, the sensing lever 9 of the displacement sensor 7 for strong wind control operation and the sensing plate 10 are always in contact with each other, and the strong wind control operation may remain in the ON state. There is.
上述の課題や虞れを解決するために、建屋の残留変位が発生した場合には、建屋自体を動かし強風時管制運転用変位感知器を初期の位置に戻す作業が必要になる。 In order to solve the above-mentioned problems and fears, when a residual displacement of the building occurs, it is necessary to move the building itself and return the displacement sensor for control operation during strong wind to the initial position.
本発明の目的は、建屋に残留変位が発生した場合でも、当該発生以降において、建屋自体を動かすことなく、簡易に且つ適切に強風時エレベータ管制運転の実行を可能にする変位感知器を提供することにある。 An object of the present invention is to provide a displacement sensor that enables an elevator control operation in a strong wind to be easily and appropriately performed without moving the building itself even when a residual displacement occurs in the building. There is.
前記課題を解決するために、本発明は主として次のような構成を採用する。
免震装置の上層又は下層建築部に取り付けられた変位感知器本体と、前記変位感知器本体の感知棒状片を挿通させるとともに前記免震装置の下層又は上層建築部に取り付けられた円形開口部をもつ感知プレートと、を備えた地震又は強風時のエレベータ管制運転用の変位感知器であって、
前記免震装置の建屋に残留変位が発生した場合、前記円形開口部をもつ感知プレートに代えて、感知プレートの円形開口部の一部に延設した切り欠き部をもつ感知プレートを採用し、前記残留変位の発生した方向に前記採用した感知プレートの前記切り欠き部が対向するように当該感知プレートを取り付け、地震又は強風時エレベータ管制運転用の変位感知器として使用可能とする構成とする。
In order to solve the above problems, the present invention mainly adopts the following configuration.
A displacement sensor body attached to the upper or lower building part of the seismic isolation device, and a circular opening attached to the lower layer or upper layer building part of the seismic isolation device through which the sensing rod-like piece of the displacement sensor body is inserted. A displacement sensor for elevator control operation in the event of an earthquake or strong wind with a sensing plate,
When a residual displacement occurs in the building of the seismic isolation device, instead of the sensing plate having the circular opening, a sensing plate having a notch extending to a part of the circular opening of the sensing plate is adopted, The sensing plate is attached so that the notch portion of the adopted sensing plate faces the direction in which the residual displacement occurs, and can be used as a displacement sensor for elevator control operation during an earthquake or strong wind.
本発明によれば、地震又は強風時に建屋に残留変位が発生した場合においても、当該発生以降において、建屋自体を動かすことなく、感知プレートの交換のみで、適切な強風時エレベータ管制運転用の変位感知器として使用することができる。 According to the present invention, even when a residual displacement occurs in the building during an earthquake or strong wind, the displacement for proper high wind elevator control operation can be performed only by exchanging the sensing plate without moving the building itself after the occurrence. Can be used as a sensor.
本発明の実施形態に係る地震又は強風時のエレベータ管制運転用の変位感知器について、図１〜図３を参照しながら以下詳細に説明する。 A displacement sensor for elevator control operation during an earthquake or strong wind according to an embodiment of the present invention will be described in detail below with reference to FIGS.

図１は本発明の実施形態に係る変位感知器を設置した免震建屋の概略構成を示す図であり、図２は本実施形態に係る変位感知器を建屋の残留変位発生後に設置した図であり、図３は本実施形態に係る変位感知器における交換用の感知プレートの構造を示す図である。 FIG. 1 is a diagram showing a schematic configuration of a seismic isolation building in which a displacement sensor according to an embodiment of the present invention is installed, and FIG. 2 is a diagram in which the displacement sensor according to this embodiment is installed after residual displacement of the building is generated. FIG. 3 is a view showing the structure of a replacement sensing plate in the displacement sensor according to the present embodiment.
図１において、通常、中間層免震建屋は上層建築部４と下層建築部５に分かれ、上層建築部４と下層建築部５の間に免震装置６を設置している。建屋の強風時管制運転用変位感知器は、上層建築部４に強風時管制運転用変位感知器７の変位感知器本体８を設置し、下層建築部５に変位感知器７の感知プレート２０を下ブラケット１２を介在させて設置し、上層建築部４と下層建築部５の変位量により（例えば、感知レバー９が円形穴開き開口部１１の周辺部に接触する変位により）、強風時エレベータ管制運転（例えば、稼働中のエレベータを低速運転にする）を行っている。なお、変位感知器本体８を下層建築部５に、感知プレート２０を上層建築部４に取り付けてもよい。 In FIG. 1, the middle layer seismic isolation building is usually divided into an upper building part 4 and a lower building part 5, and a seismic isolation device 6 is installed between the upper building part 4 and the lower building part 5. In the building, the displacement sensor for strong wind control operation is provided with the displacement sensor body 8 of the displacement sensor 7 for strong wind control operation in the upper building part 4, and the sensing plate 20 of the displacement sensor 7 in the lower building part 5. Installed with the lower bracket 12 interposed, and depending on the amount of displacement of the upper building part 4 and the lower building part 5 (for example, due to the displacement of the sensing lever 9 in contact with the peripheral part of the circular hole opening 11), Driving (for example, changing the operating elevator to low speed operation) is performed. The displacement sensor body 8 may be attached to the lower building part 5 and the sensing plate 20 may be attached to the upper building part 4.
ここで、地震や強風の影響で建屋における上層建築部４と下層建築部５の間に残留変位が発生した場合、図４に示す感知プレート１０を用いている場合、変位感知器本体８の感知レバー（感知棒状片であればよい）９が感知プレート１０の円形穴開き開口部１１の中央部からずれた位置に保持されることとなって、当該保持状態ではこれ以降における適切な強風時エレベータ管制運転を行うことができない（ずれた位置に保持された感知レバー９と感知プレート１０の円形穴開き開口部１１との間の離隔距離に大きなばらつきが生じるから）。 Here, when a residual displacement occurs between the upper building part 4 and the lower building part 5 in the building due to the influence of an earthquake or strong wind, when the sensing plate 10 shown in FIG. 4 is used, the sensing of the displacement sensor body 8 is performed. The lever (which may be a sensing rod-like piece) 9 is held at a position shifted from the center of the circular hole opening 11 of the sensing plate 10, and in this holding state, an appropriate strong wind elevator thereafter. The control operation cannot be performed (because there is a large variation in the separation distance between the sensing lever 9 held at the shifted position and the circular hole opening 11 of the sensing plate 10).
また、建屋の残留変位量の大きさによっては、強風時管制運転用変位感知器７の感知レバー９と感知プレート１０が接触している状態を保持することとなり（図５を参照）、強風時管制運転（例えば、エレベータの低速運転など）がＯＮ状態のままになってしまう虞れがある。 Further, depending on the amount of residual displacement of the building, the sensing lever 9 of the displacement sensor 7 for strong wind control operation and the sensing plate 10 are kept in contact with each other (see FIG. 5). There is a possibility that the control operation (for example, the low-speed operation of the elevator) remains in the ON state.
上述したような建屋の残留変位に対して、建屋自体をこの残留変位が無くなるように移動させて、感知プレート１０の円形穴開き開口部１１に対して感知レバー９を初期位置に戻す必要があるが、本実施形態では建屋自体を動かさずに、以下に説明するように簡易に適切に強風時管制運転を可能にするものである。。 In response to the residual displacement of the building as described above, it is necessary to return the sensing lever 9 to the initial position with respect to the circular hole opening 11 of the sensing plate 10 by moving the building itself so that the residual displacement is eliminated. However, in this embodiment, it is possible to easily and appropriately control the strong wind operation as described below without moving the building itself. .
そこで、本実施形態に係る残留変位時の交換用変位感知器７は、図２と図３に示すように、円形穴開き開口部１１の周辺の一部に円弧形切り欠き部２１を延設した感知プレート２０の構造を採用したものである。さらに、感知プレート２０は、如何なる回転位置でも下ブラケット１２に取り付けられるように、留め具２２の挿通する留め具用溝２３を、円形穴開き開口部１１の中心位置に対して円弧状に沿って形成している。これによって、残留変位がどの方向に発生しても対応できるようにしている。 Therefore, in the displacement sensor 7 for residual displacement according to the present embodiment, as shown in FIGS. 2 and 3, the arc-shaped notch 21 is extended to a part of the periphery of the circular hole opening 11. The structure of the provided sensing plate 20 is adopted. Furthermore, the sensing plate 20 has a fastener groove 23 through which the fastener 22 is inserted along an arc shape with respect to the center position of the circular hole opening 11 so that the sensing plate 20 can be attached to the lower bracket 12 at any rotational position. Forming. This makes it possible to cope with any direction of residual displacement.
ここで、図２と図３の例示では、感知プレート２０の外径形状は四角であるが円形であってもよい。また、図４に示す当初に設置した感知プレート１０は、その円形開口部１１の中心位置から円形開口部１１の周辺部までの距離が一例として２０ｍｍであるとすれば、図２に示す残留変位発生時の感知レバー９と円弧形切り欠き部２１の周辺部までの離隔距離が２０ｍｍ以下の適宜の距離になるように円弧形切り欠き部２１を形成するのである。なお、交換後の感知プレート２０の配置構成を示す図２において、感知レバー９と、円弧形切り欠き部２１の反対側の円形開口部１１周辺部と、の離隔距離は略４０ｍｍになり、強風時に当該方向に略４０ｍｍ変位して初めて管制運転がオン（ＯＮ）状態となるが、上層建築部４と下層建築部５の初期位置から判断すると（図２の図示例で、元々２０ｍｍ左方変位している）、略４０ｍｍだけ右方変位して管制運転がオン状態となることに問題はないのである（元の初期位置から右方向に２０ｍｍ動いたときにオン状態となることに外ならないから）。 Here, in the illustration of FIG. 2 and FIG. 3, the outer diameter shape of the sensing plate 20 is a square, but may be a circle. Moreover, the sensing plate 10 initially installed in FIG. 4 has a residual displacement shown in FIG. 2 if the distance from the center position of the circular opening 11 to the peripheral part of the circular opening 11 is 20 mm as an example. The arcuate notch 21 is formed so that the distance between the sensing lever 9 and the peripheral part of the arcuate notch 21 at the time of occurrence is an appropriate distance of 20 mm or less. In FIG. 2 showing the arrangement configuration of the sensing plate 20 after replacement, the separation distance between the sensing lever 9 and the periphery of the circular opening 11 on the opposite side of the arc-shaped notch 21 is about 40 mm. The control operation is turned on only when it is displaced by about 40 mm in the direction of strong wind, but judging from the initial positions of the upper building part 4 and the lower building part 5 (in the illustrated example of FIG. There is no problem that the control operation is turned on by shifting the position by approximately 40 mm to the right (the displacement is in the on state when moved 20 mm to the right from the original initial position). From).
換言すると、建屋の残留変位の発生時における交換用の感知プレートは、残留変位方向に円弧状に切り欠いた形状の感知プレート２０で構成している。さらに、残留変位時の交換用の感知プレート２０は回動自在の取り付けが可能な構造をしており、図３に示すような留め具用円弧状溝２３が形成されている。すなわち、どの方向に建屋残留変位が発生しても、円弧状の切り欠き部２１が残留変位方向に合うように下ブラケット１２に取り付けられる。例えば、残留変位が右方向に発生した場合、標準構造の円形状開口部１１の感知プレート１０から、円弧状切り欠き部２１を右向きにした残留変位時の感知プレート２０に交換し取り付けることによって、これ以降の強風時エレベータ管制運転に用いることのできる変位感知器７とすることができる。 In other words, the sensing plate for replacement when the residual displacement of the building is generated is constituted by the sensing plate 20 having a shape cut out in an arc shape in the residual displacement direction. Further, the replacement sensing plate 20 at the time of residual displacement has a structure that can be pivotably attached, and a circular arc groove 23 for a fastener as shown in FIG. 3 is formed. That is, regardless of the direction in which the building residual displacement occurs, the arcuate notch 21 is attached to the lower bracket 12 so as to match the residual displacement direction. For example, when the residual displacement occurs in the right direction, by replacing the sensing plate 10 of the circular opening 11 of the standard structure with the sensing plate 20 at the time of residual displacement with the arc-shaped notch 21 facing right, It can be set as the displacement sensor 7 which can be used for the elevator control operation at the time of a strong wind after this.
また、建屋残留変位の発生時における交換用の感知プレート２０は、図５に示すように感知レバー９が円形開口部１１の周辺部に接触して例えば残留変位が略２０ｍｍである場合には、例示として略２０ｍｍの円弧形切り欠き部２１のある予め準備した感知プレート２０を用い、また、例えば残留変位が１５ｍｍである場合には、例示として略１５ｍｍの円弧形切り欠き部２１のある予め準備した感知プレート２０を用いてもよい。このように、適宜の寸法で適宜の形状の切り欠き部を交換用の感知プレート２０として予め準備しておいて、残留変位に大きさに応じて適用すべき感知プレートを適宜選定すればよい。 Further, the replacement sensing plate 20 at the time of occurrence of the residual building displacement is, as shown in FIG. 5, when the sensing lever 9 is in contact with the peripheral portion of the circular opening 11 and the residual displacement is about 20 mm, for example. For example, when the sensing plate 20 prepared in advance having the arc-shaped cutout portion 21 having a substantially 20 mm is used, and the residual displacement is 15 mm, for example, the arc-shaped cutout portion 21 having the approximately 15 mm is illustrated. A sensing plate 20 prepared in advance may be used. In this way, a notch having an appropriate size and an appropriate shape may be prepared in advance as the replacement sensing plate 20, and the sensing plate to be applied to the residual displacement may be selected as appropriate.
以上説明したように、本実施形態に係る感知プレートによれば、建屋に残留変位が発生しても強風時エレベータ管制運転用変位感知器７の感知レバー９と感知プレート２０の離隔距離を調整でき、残留変位発生以降の適切な強風時エレベータ管制運転を実施できるものである。 As described above, according to the sensing plate according to the present embodiment, the separation distance between the sensing lever 9 and the sensing plate 20 of the displacement sensor 7 for elevator control operation during strong winds can be adjusted even if residual displacement occurs in the building. Thus, it is possible to carry out appropriate high wind elevator control operation after the occurrence of residual displacement.
