【発明の属する技術分野】
本発明は、上下に２個のかご室を有し２個のかご室のかご間を調整するかご間調整制御装置を備えたダブルデッキエレベータの制御装置に関する。
【０００２】
【従来の技術】
超高層ビル等ではビルのスペース効率を向上するために、かご室を上下２段に構成し大量輸送が可能なダブルデッキエレベータが用いられている。ダブルデッキエレベータでは、建物の１階床の高さが一定でない場合にも、上下のかご室がほぼ同時に着床できるように２個のかご室のかご間を調整するためのかご間調整制御装置が設けられている。すなわち、建物の１階床の高さが一定でない場合であってもかご間を調整し、着床時に各階床に段差なく着床できるようにしている。
【０００３】
かご間調整制御装置としては、上下２個のかご室の一方のかご室に駆動装置を取付けてかご室の高さを変化させ、上下のかご室間の距離を変化させるようにしたものがある（例えば特許文献１参照）。また、クランク機構を用いて上下のかご室の重量をバランスさせながらそれぞれ反対方向に移動させることにより、少ない消費電力で上下のかご室間の距離を可変したものもある（例えば特許文献２参照）。
【０００４】
このような上下かご室間調整機能を持つダブルデッキエレベータでは、エレベータ運転中にかご室間の距離を調整し、着床時には各階床に段差なく着床できるようにし、乗客に不安感や不快感を感じないようにしている。

【発明が解決しようとする課題】
しかしながら、上下かご室間の距離を変化させるかご間調整制御装置が故障した場合は、上下のかご室が同時に着床できなくなるので、エレベータの故障として運転を中止することになる。エレベータの故障として運転を中止した場合には、乗客をかご室内に閉じ込めてしまう重大故障となり、乗客に不安感や不快感を生じさせてしまう。そのため、上下かご室間の距離を変化させるかご間調整制御装置が故障した場合でも上下かご室内の乗客に不安感を生じさせないように乗客救出させることが必要となる。
【０００８】
本発明の目的は、かご間調整制御装置が故障したとしても乗客をかご室内に閉じ込めることを極力防止できるダブルデッキエレベータの制御装置を提供することである。
【０００９】
【課題を解決するための手段】
請求項１の発明に係わるダブルデッキエレベータの制御装置は、上下に２個のかご室を搭載したかご枠を昇降制御するかご枠制御装置と、前記２個のかご室をかご間調整装置を駆動して上下のかご室の相対距離を変化させ上下のかご間を調整するかご間調整制御装置と、前記かご間調整制御装置の異常時に救出運転を行う救出運転装置とを備え、前記救出運転装置は、前記かご間調整制御装置による上下のかご間の調整ができなくなった異常を検出する異常検出手段と、前記異常検出手段がかご間調整異常を検出したとき前記かご枠を上下かご室共に戸開可能な階に着床させる着床制御手段と、前記着床制御手段により着床した上下かご室の着床位置が共に戸開位置であるときは上下かご室共に戸開させ、前記上下かご室の着床位置が共に戸開位置を外れていたときは、前記かご枠を上方または下方のいずれかの方向に走行させ、先に戸開位置に到達したかごを戸開させ、その後、他方のかごを戸開位置まで走行させて戸開させる救出動作手段とを備えたダブルデッキエレベータの制御装置において、前記救出動作手段は、前記上下かご室の一方のかごの着床位置が戸開位置であり、他方のかごの着床位置が前記かご間調整装置でかご間調整を行う範囲である戸開許可範囲内の戸開位置を外れた位置であるときは、先に戸開位置のかごを戸開させ、その後、他方のかごを戸開位置まで走行させて戸開させるとともに、他方のかごの着床位置が前記戸開許可範囲外であるときは、戸開位置のかごを戸開させ、その後、その位置で故障停止させることを特徴とする。
【００２３】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。図１は本発明の実施の形態に係るダブルデッキエレベータの制御装置のブロック構成図である。かご枠１１には、上かご室１２および下かご室１３が搭載され、上かご室１２および下かご室１３の間にかご間調整装置１４が設けられている。
【００２４】
上かご室１２および下かご室１３を搭載したかご枠１１はロープ１５を介してカウンタウエイト１６に連結され、巻上機１７のシーブで駆動され昇降することになる。巻上機１７にはかご位置検出器（図示省略）が設けられ、かご枠１１の位置が検出される。このかご位置検出器で検出されたかご位置信号は、かご枠制御装置１８および救出運転装置１９に入力される。
【００２５】
一方、かご間調整装置１４により駆動されるかご室のかご位置信号は、かご室位置検出器（図示省略）により検出され、かご間調整制御装置２０に入力される。かご間調整制御装置２０は、行先階の階高寸法に基づいて上下のかご室１２、１３のかご間の距離を調整する。また、かご室のかご位置信号はかご枠制御装置１８および救出運転装置１９にも入力され、通常運転時や救出運転時の着床制御に用いられる。
【００２６】
救出運転装置１９は、かご間調整制御装置２０の異常時に救出運転を行うものであり、かご間調整制御装置による上下のかご間の調整ができなくなった異常を検出する異常検出手段２１と、異常検出手段２１がかご間調整異常を検出したときかご枠１１を上下かご室共に戸開可能な階に着床させる着床制御手段２２と、着床制御手段２２により着床した上下かご室の着床位置が共に戸開位置であるときは上下かご室共に戸開させる救出動作手段２３とから構成されている。
【００２７】
また、上下かご室１２、１３には、救出運転装置１９による救出運転の案内を報知するための報知装置２４が設けられている。この報知装置２４には救出運転の開始や乗客への救出案内等が出力される。
【００２８】
いま、かご間調整制御装置２０が何らかの要因により故障し、上下かご室１２、１３間の調整が不可能となったとする。この異常状態は異常検出手段２１で検出され、異常検出手段２１はかご間調整異常を検出すると、かご間調整制御装置２０の制御を停止させると共に着床制御手段２２を起動する。着床制御手段２２は、上下かご室１２、１３共に戸開可能な最寄階にかご枠１１を着床させる。
【００２９】
救出動作手段２３は、着床制御手段２２により着床した上下かご室１２、１３の着床位置を判定し、上下かご室１２、１３の着床位置が共に戸開位置であるときは、上下かご室１２、１３共に戸開させ、上下かご室１２、１３内の乗客を救出する。
【００３０】
図２は、最寄階での着床時の上下かご室１２、１３共に戸開位置に着床しているときのかご位置の説明図である。救出運転装置１９の救出動作手段２３は、上下かご室１２、１３共に戸開位置に着床しているので、上下かご室１２、１３共に戸開させ乗客を救出することになる。
【００３１】
このように、かご間調整制御装置２０が異常となったとき、即座にエレベータの故障として運転を中止するのではなく、上下かご室１２、１３共に戸開できる位置に停止している場合には、戸開して乗客を救出するので、上下かご室１２、１３内に乗客を閉じ込めることを防止できる。
【００３２】
次に、図３は最寄階での着床時の上下かご室１２、１３の着床位置が共に戸開位置を外れているときのかご位置の説明図である。
【００３３】
かご間調整制御装置２０の異常発生時の着床制御後の状態として、図３に示すように、上下かご室１２、１３共に戸開位置を外れていた場合は、救出動作手段２３は、かご枠１１を上方または下方いずれかの方向に走行させ、先に戸開位置に到達したかごを戸開させて乗客を救出する。そして、その後に、他方のかごを戸開位置まで走行させて戸開させ、他のかごの乗客を救出する。
【００３４】
すなわち、異常検出手段２１によりかご間調整制御装置２０の異常が検出されると、着床制御手段２２は最寄階にかご枠１１を着床させる。ここで、救出動作手段２３は、最寄階に着床時のかご位置を判定し、着床時の上下かご室１２、１３の位置が図３に示す状態である場合には、上下かご室１２、１３共に戸開位置から外れているので、例えば、かご枠１１を下方に走行させる。その場合、下かご室１３が先に戸開位置に到達するので、下かご室１３を先に着床させて戸開し下かご１３の乗客を救出する。次に、かご枠１１を上方に走行させ、上かご１２を戸開位置に着床させて戸開し上かご１２の乗客を救出する。
【００３５】
このように、かご間調整制御装置２０が異常となったとき、即座にエレベータの故障として運転を中止するのではなく、最寄階に着床させ、その着床位置を判定して、上下かご室１２、１３共に戸開位置を外れていた場合は、かご枠１１を上方または下方いずれかの方向に走行させ、先に戸開位置に到達したかごを戸開させ、その後、他方のかごを戸開位置まで走行させて戸開させて乗客を救出する。従って、上下かご室１２、１３内に乗客を閉じ込めることを防止できる。
【００３６】
次に、図４は最寄階での着床時の上下かご室１２、１３の一方のかごの着床位置が戸開位置であり他方のかごの着床位置が戸開許可範囲内の戸開位置を外れた位置であるときのかご位置の説明図である。
【００３７】
かご間調整制御装置２０の異常発生時の着床制御後の状態として、図４に示すように、上下かご室１２、１３の一方のかごの着床位置が戸開位置であり他方のかごの着床位置が戸開許可範囲内の戸開位置を外れた位置である場合には、救出動作手段２３は、先に戸開位置のかごを戸開させて乗客を救出し、その後に、他方のかごの戸開位置まで、かご枠１１を上方または下方いずれかの方向に走行させ戸開させて乗客を救出する。
【００３８】
すなわち、異常検出手段２１によりかご間調整制御装置２０の異常が検出されると、着床制御手段２２は最寄階にかご枠１１を着床させる。ここで、救出動作手段２３は、最寄階に着床時のかご位置を判定し、着床時の上下かご室１２、１３の位置が図４に示す状態である場合には、上かご室１２が戸開位置に着床しているので、その場で上かご１２を戸開し、上かご１２の乗客を救出する。次に、かご枠１１を下方に走行させ、下かご１３を戸開位置に着床させて戸開し下かご１３の乗客を救出する。
【００３９】
ここで、他方のかごの着床位置が戸開許可範囲内であるか否かを判定しているのは、かご間調整装置１４（かご間を調整する機構部分）の異常であるか否かを判定するためである。戸開許可範囲とは、かご間調整装置でかご間調整を行う範囲をいう。従って、かご間調整装置１４は戸開許可範囲内でかご間調整を行うので、一方のかご室が戸開位置で着床している場合には、他方のかごはかご間調整装置１４が異常でない限りは戸開許可範囲内にある。そこで、かご間調整装置１４が異常でないことを確認して他方のかごの救出運転を行うこととしている。
【００４０】
このように、かご間調整制御装置２０が異常となったとき、即座にエレベータの故障として運転を中止するのではなく、最寄階に着床させ、その着床位置を判定して、上下かご室１２、１３の一方のかごの着床位置が戸開位置であり他方のかごの着床位置が戸開許可範囲内の戸開位置を外れた位置である場合には、救出動作手段２３は、先に戸開位置のかごを戸開させて乗客を救出し、その後に、他方のかごの戸開位置まで、かご枠１１を上方または下方いずれかの方向に走行させ戸開させて乗客を救出する。従って、上下かご室１２、１３内に乗客を閉じ込めることを防止できる。
【００４１】
次に、図５は最寄階での着床時の上下かご室１２、１３の一方のかごの着床位置が戸開位置であり、他方のかごの着床位置が戸開許可範囲外であるときのかご位置の説明図である。
【００４２】
かご間調整制御装置２０の異常発生時の着床制御後の状態として、図５に示すように、上下かご室１２、１３の一方のかごの着床位置が戸開位置であり、他方のかごの着床位置が戸開許可範囲外である場合には、救出動作手段２３は、先に戸開位置のかごを戸開させて乗客を救出し、その後、その位置で故障停止させる。
【００４３】
前述したように、かご間調整装置１４は戸開許可範囲内でかご間調整を行うので、一方のかご室が戸開位置で着床している場合には、他方のかごはかご間調整装置１４が異常でない限りは戸開許可範囲内にある。従って、一方のかご室が戸開位置で着床している状態で、他方のかごが戸開許可範囲外であるときは、かご間調整装置１４自体（かご間を調整する機構部分）の異常であると判断できる。
【００４４】
そこで、かご間調整制御装置２０の異常時に、上下かご室１２、１３のかご位置が救出運転可能なかご位置の条件を満たしていない場合には、救出運転を行わないようにしたものである。
【００４５】
すなわち、異常検出手段２１によりかご間調整制御装置２０の異常が検出されると、着床制御手段２２は最寄階にかご枠１１を着床させる。ここで、救出動作手段２３は、最寄階に着床時のかご位置を判定し、着床時の上下かご室１２、１３の位置が図５に示す状態である場合には、上かご１２は戸開位置に着床しており下かご１３が戸開可能範囲を外れている。つまり、上下かご室１２、１３の中心点が大きくずれていることから、かご間を調整する機構部分の破損と判断し、戸開位置に着床している上かご１２を戸開させて上かご１２の乗客を救出し、もう一方の下かご１３の救出運転を行わず、その場で故障停止させる。
【００４６】
このように、上下かご室１２、１３の中心点が大幅にずれている場合には、かご間調整装置１４自体（かご間を調整する機構部分）の異常であると判断し、救出運転を中止して乗客の安全を図る。この場合、下かご室１３の乗客は一時的にかご内に閉じこめられることになるが、別の救出方法で救出されるることは言うまでもない。また、報知装置２４からその旨の案内が出力されることは言うまでもない。
【００４７】
かご間調整制御装置２０が異常となった場合には、以上述べたような救出運転を行うが、その救出運転の完了後に、上下かご室１２、１３内の戸開ボタンが押されたときは、そのかご室に対して再度、同じ救出運転を行うようにしても良い。
【００４８】
いま、救出運転の完了した状態が図４に示す状態であったとする。この状態のときに上かご室１２の戸開ボタンが押されたとすると、救出動作手段２３は、上かご室１２が戸開位置に着床しているので、その場で戸開させて乗客を救出する。
【００４９】
また、下かご室１３の戸開ボタンが押されたとする。救出運転装置１９は、かご枠１１を下方に走行させ、下かご１３を戸開位置に着床させて戸開し乗客を救出することになる。
【００５０】
また、かご間調整制御装置２０の異常時に、上下かご室１２、１３共に戸開位置を外れていた場合に、かご枠１１を走行させる方向として、カウンタウエイト１６と離れる方向にかご枠１１を走行させるようにする。このようにすることにより、救出運転中にかご室１２、１３とカウンタウエイト１６とがすれ違うことがなくなるので、かご室１２、１３に破損が発生し破損物が突出していた場合に、その破損物がカウンタウエイト１６と衝突することを防止でき、乗客の安全が図れる。
【００５１】
いま、最寄階に着床時の上下かご室１２、１３のかご位置が図３で示す状態であるとし、かご枠１１とカウンタウエイト１６の位置関係が図１に示す状態であるとする。救出動作手段２３は、かご枠１１をカウンタウエイト１６と離れる下方に走行させ救出運転を行う。これにより、かご枠１１に搭載されたかご機器の破損を考慮して、かご室１２、１３とカウンタウエイト１６とがすれ違うことをなくし乗客の安全を図っている。
【００５２】
【発明の効果】
以上に説明したように、本発明によれば、上下かご室間の距離を変化させるかご間調整制御装置が異常となった場合、即座にエレベータの故障として運転を中止するのではなく、可能な限り上下かご室の乗客を救出するので、乗客をかご内に閉じ込める重大故障を極力防止できる。

[Prior art]
In order to improve the space efficiency of high-rise buildings, etc., double deck elevators that can be transported in large quantities by using two tiers of cabs are used. In a double-deck elevator, even if the height of the first floor of the building is not constant, the adjustment system for adjusting the space between the two cabs so that the upper and lower cabs can be landed almost simultaneously. Is provided. That is, even when the height of the first floor of the building is not constant, the distance between the cars is adjusted so that the floor can be landed on the floor without any steps when landing.
[0003]
As an adjustment control device between the cars, there is one in which a driving device is attached to one of the two upper and lower cabs to change the height of the cab and change the distance between the upper and lower cabs. (For example, refer to Patent Document 1). In addition, there is a type in which the distance between the upper and lower cabs can be changed with less power consumption by moving them in opposite directions while balancing the weights of the upper and lower cabs using a crank mechanism (see, for example, Patent Document 2). .
[0004]
In such a double deck elevator with the function of adjusting the space between the upper and lower cabs, the distance between the cabs is adjusted during operation of the elevator so that the floor can be stepped on the floor without any steps, and the passengers feel uneasy or uncomfortable. I do not feel it.

It is characterized by being stopped .
[0023]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. FIG. 1 is a block diagram of a control device for a double deck elevator according to an embodiment of the present invention. An upper car room 12 and a lower car room 13 are mounted on the car frame 11, and an inter-car adjusting device 14 is provided between the upper car room 12 and the lower car room 13.
[0024]
The car frame 11 on which the upper car room 12 and the lower car room 13 are mounted is connected to a counterweight 16 via a rope 15 and is driven by a sheave of a hoisting machine 17 to move up and down. The hoisting machine 17 is provided with a car position detector (not shown) to detect the position of the car frame 11. The car position signal detected by the car position detector is input to the car frame control device 18 and the rescue operation device 19.
[0025]
On the other hand, the car position signal of the car room driven by the car space adjusting device 14 is detected by a car room position detector (not shown) and inputted to the car space adjusting control device 20. The car-to-car adjustment control device 20 adjusts the distance between the upper and lower car rooms 12 and 13 based on the floor height of the destination floor. The car position signal of the car room is also input to the car frame control device 18 and the rescue operation device 19, and is used for landing control during normal operation or rescue operation.
[0026]
The rescue operation device 19 performs rescue operation when the car-to-car adjustment control device 20 is abnormal, and includes an abnormality detection means 21 that detects an abnormality in which the upper and lower cars cannot be adjusted by the car-to-car adjustment control device, When the detection means 21 detects an abnormality in the adjustment between the cars, the landing control means 22 for landing the car frame 11 on the floor that can be opened in both the upper and lower cabs, and the landing of the upper and lower cabs that are landed by the landing control means 22 When the floor position is the door open position, rescue operation means 23 is configured to open both the upper and lower cabs.
[0027]
The upper and lower cabs 12 and 13 are provided with a notification device 24 for notifying the rescue operation guidance by the rescue operation device 19. The notification device 24 outputs the start of rescue operation, rescue guidance to passengers, and the like.
[0028]
Now, it is assumed that the car-to-car adjustment control device 20 has failed due to some cause and adjustment between the upper and lower car rooms 12 and 13 becomes impossible. This abnormal state is detected by the abnormality detection means 21, and when the abnormality detection means 21 detects a car-to-car adjustment abnormality, the control of the car-to-car adjustment control device 20 is stopped and the landing control means 22 is activated. The landing control means 22 causes the car frame 11 to land on the nearest floor where both the upper and lower cabs 12 and 13 can be opened.
[0029]
The rescue operation means 23 determines the landing positions of the upper and lower cabs 12 and 13 landed by the landing control means 22, and when the landing positions of the upper and lower cabs 12 and 13 are both door open positions, Both the cabs 12 and 13 are opened, and passengers in the upper and lower cabs 12 and 13 are rescued.
[0030]
2, Ru illustration der the car position when being implanted in the upper and lower cage chambers 12 and 13 together with door open position of the wearing time of the floor in the nearest floor. Since the rescue operation means 23 of the rescue operation device 19 is both in the upper and lower cabs 12 and 13, the rescue operation means 23 rescues the passenger by opening both the upper and lower cabs 12 and 13.
[0031]
In this way, when the car adjustment control device 20 becomes abnormal, the operation is not immediately stopped as an elevator failure, but when the upper and lower cabs 12 and 13 are both stopped at a position where they can be opened. Since the door is opened and the passenger is rescued, it is possible to prevent the passenger from being trapped in the upper and lower cabs 12 and 13.
[0032]
Next, FIG. 3 is Ru illustration der the car position when you are out of the landing zone are both the door-open position of the upper and lower cage chambers 12 and 13 of the wearing time of the floor in the nearest floor.
[0033]
As shown in FIG. 3, when both the upper and lower cabs 12 and 13 are out of the door open position as a state after the landing control at the time of occurrence of abnormality of the car adjusting control device 20, the rescue operation means 23 is The frame 11 is made to travel either upward or downward, and the car that has reached the door opening position first is opened to rescue the passenger. After that, the other car travels to the door open position to open the door, and rescues the passengers in the other car.
[0034]
That is, when the abnormality detection means 21 detects an abnormality in the car space adjustment control device 20, the landing control means 22 places the car frame 11 on the nearest floor. Here, the rescue operation means 23 determines the position of the car at the time of landing on the nearest floor, and when the positions of the upper and lower car rooms 12 and 13 at the time of landing are in the state shown in FIG. Since both 12 and 13 are out of the door open position, for example, the car frame 11 is caused to travel downward. In this case, since the lower cab 13 reaches the door opening position first, the lower cab 13 is landed first, the door is opened, and the passengers in the lower cab 13 are rescued. Next, the car frame 11 is moved upward, the upper car 12 is landed at the door open position, the door is opened, and the passengers in the upper car 12 are rescued.
[0035]
In this way, when the car adjustment control device 20 becomes abnormal, the operation is not immediately stopped as an elevator failure, but the operation is stopped, the floor is landed on the nearest floor, the landing position is determined, and the upper and lower cars are If both of the chambers 12 and 13 are out of the door open position, the car frame 11 is run in either the upward or downward direction, the car that has reached the door open position first is opened, and then the other car is opened. Travel to the door open position and open the door to rescue the passengers. Therefore, it is possible to prevent passengers from being trapped in the upper and lower cabs 12 and 13.
[0036]
Next, FIG. 4 shows that the landing position of one of the upper and lower cabs 12 and 13 at the time of landing on the nearest floor is the door opening position, and the landing position of the other car is within the door opening permission range. Ru illustration der the car position when a position off the open position.
[0037]
As shown in FIG. 4, as the state after the landing control at the time of occurrence of an abnormality in the car-to-car adjustment control device 20, the landing position of one of the upper and lower cabs 12 and 13 is the door open position, and the other car If the landing position is outside the door opening position within the door opening permission range, the rescue operation means 23 first opens the car at the door opening position to rescue the passenger, and then the other side The car frame 11 travels in either the upward or downward direction to the door open position of the car and opens the door to rescue the passenger.
[0038]
That is, when the abnormality detection means 21 detects an abnormality in the car space adjustment control device 20, the landing control means 22 places the car frame 11 on the nearest floor. Here, the rescue operation means 23 determines the position of the car at the time of landing on the nearest floor, and when the positions of the upper and lower car rooms 12 and 13 at the time of landing are in the state shown in FIG. Since 12 is landing at the door open position, the upper car 12 is opened on the spot, and the passengers in the upper car 12 are rescued. Next, the car frame 11 is moved downward, the lower car 13 is landed at the door open position, the door is opened, and the passengers in the lower car 13 are rescued.
[0039]
Here, whether or not the landing position of the other car is within the door opening permission range is whether or not the car space adjusting device 14 (mechanism part for adjusting the space between the cars) is abnormal. This is for determining. The door opening permission range refers to a range in which the car space is adjusted by the car space adjusting device. Therefore, the car space adjusting device 14 performs the car space adjustment within the door opening permission range, so that when one of the cabs is landed at the door open position, the other car has an abnormality in the car space adjusting device 14. Unless it is, it is within the door opening permission range. Therefore, it is determined that the car adjusting device 14 is not abnormal and the other car is rescued.
[0040]
In this way, when the car adjustment control device 20 becomes abnormal, the operation is not immediately stopped as an elevator failure, but the operation is stopped, the floor is landed on the nearest floor, the landing position is determined, and the upper and lower cars are When the landing position of one of the cars in the chambers 12 and 13 is the door opening position and the landing position of the other car is a position outside the door opening position within the door opening permission range, the rescue operation means 23 is First, the car at the door open position is opened and the passenger is rescued, and then the car frame 11 is run in either the upward or downward direction to the door open position of the other car, and the passenger is opened. Rescue. Therefore, it is possible to prevent passengers from being trapped in the upper and lower cabs 12 and 13.
[0041]
Next, FIG. 5 shows that the landing position of one of the upper and lower cabs 12 and 13 when landing on the nearest floor is the door opening position, and the landing position of the other car is outside the door opening permission range. Ru illustration der cage position of a time.
[0042]
As shown in FIG. 5, as the state after the landing control at the time of occurrence of abnormality of the car adjusting control device 20, the landing position of one of the upper and lower cabs 12 and 13 is the door open position, and the other car When the landing position is outside the door opening permission range, the rescue operation means 23 first opens the car at the door opening position to rescue the passenger, and then stops the failure at that position.
[0043]
As described above, the car space adjusting device 14 adjusts the car space within the door opening permission range. Therefore, when one of the car rooms is landing at the door open position, the other car is the car space adjusting device. Unless 14 is abnormal, it is within the door opening permission range. Therefore, when one of the cabs is landed at the door open position and the other car is outside the door opening permission range, an abnormality in the car space adjusting device 14 itself (mechanism part for adjusting the space between the cars). It can be judged that.
[0044]
Therefore, when the car adjustment control device 20 is abnormal, the rescue operation is not performed when the car positions of the upper and lower cabs 12 and 13 do not satisfy the condition of the car position where the rescue operation is possible.
[0045]
That is, when the abnormality detection means 21 detects an abnormality in the car space adjustment control device 20, the landing control means 22 places the car frame 11 on the nearest floor. Here, the rescue operation means 23 determines the car position at the time of landing on the nearest floor, and when the positions of the upper and lower cabs 12 and 13 at the time of landing are in the state shown in FIG. Is in the door open position and the lower car 13 is out of the door openable range. In other words, since the center points of the upper and lower cabs 12 and 13 are greatly deviated, it is determined that the mechanism part for adjusting the distance between the cars is broken, and the upper car 12 that is landing at the door open position is opened. The passenger in the car 12 is rescued, and the rescue operation of the other lower car 13 is not performed, and the vehicle is stopped on the spot.
[0046]
As described above, when the center points of the upper and lower cabs 12 and 13 are greatly deviated, it is determined that the car adjusting device 14 itself (mechanism for adjusting the car space) is abnormal, and the rescue operation is stopped. To ensure passenger safety. In this case, passengers in the lower cab 13 are temporarily confined in the car, but needless to say, they are rescued by another rescue method. Needless to say, the notification device 24 outputs a guidance to that effect.
[0047]
When the car adjustment control device 20 becomes abnormal, the rescue operation as described above is performed, but when the door opening buttons in the upper and lower cabs 12 and 13 are pressed after the rescue operation is completed. The same rescue operation may be performed again for the cab.
[0048]
Assume that the rescue operation is completed as shown in FIG. If the door opening button of the upper car room 12 is pressed in this state, the rescue operation means 23 opens the door on the spot so that the passenger can move the passenger because the upper car room 12 is landed at the door opening position. Rescue.
[0049]
It is assumed that the door opening button of the lower cab 13 is pressed. The rescue operation device 19 travels the car frame 11 downward, causes the lower car 13 to land at the door open position, opens the door, and rescues the passenger.
[0050]
In addition, when the upper and lower cabs 12 and 13 are out of the door open position when the car adjustment control device 20 is abnormal, the car frame 11 travels away from the counterweight 16 as the direction in which the car frame 11 travels. I will let you. By doing in this way, the cabs 12 and 13 and the counterweight 16 do not pass each other during the rescue operation, so that when the cabs 12 and 13 are damaged and the damaged items protrude, Can be prevented from colliding with the counterweight 16, and passenger safety can be achieved.
[0051]
Assume that the car positions of the upper and lower cabs 12 and 13 when landing on the nearest floor are in the state shown in FIG. 3, and the positional relationship between the car frame 11 and the counterweight 16 is in the state shown in FIG. The rescue operation means 23 performs the rescue operation by running the car frame 11 downward away from the counterweight 16. Accordingly, in consideration of breakage of the car equipment mounted on the car frame 11, the car compartments 12 and 13 and the counterweight 16 are prevented from passing each other and passenger safety is achieved.
[0052]
【The invention's effect】
As described above, according to the present invention, when the car adjustment control device that changes the distance between the upper and lower cabs becomes abnormal, it is possible not to immediately stop the operation as an elevator failure, but to As long as passengers in the upper and lower cabs are rescued, it is possible to prevent as much as possible a serious failure that traps the passengers in the car.
