Description

本発明は、かご枠内に上下２つのかごを有するダブルデッキエレベーター装置に関する。   The present invention relates to a double deck elevator apparatus having two upper and lower cars in a car frame.

かご枠内に上下２つのかごを有し、上かごの上部に駆動手段を設置し、この駆動手段とロープで連結された上かごのかご下、及び下かごのかご下に設けたプーリにロープを掛け渡し、駆動手段により上かご及び下かごを駆動する構成となっているダブルデッキエレベーター装置が知られている。   There are two upper and lower cars in the car frame, the driving means is installed on the upper part of the upper car, and the ropes are connected to the pulleys provided below the upper car and the lower car connected to the driving means by the rope. There is known a double deck elevator apparatus that is configured to drive an upper car and a lower car by driving means.

このように構成されるダブルデッキエレベーター装置に適用され、上かご及び下かごを駆動するロープ切れ時のかごの落下を検出するものとして従来、かご下にあってロープに当接するように検出ローラーを配置しロープの異常な緩み、及びロープの切断に応じて検出ローラーが変位し、非常止め装置を動作させるものがあった（例えば、特許文献１参照）。   As applied to the double-deck elevator device constructed as described above, a detection roller is used to detect the fall of the car when the rope that drives the upper car and the lower car is broken. In some cases, the detection roller is displaced in response to the abnormal loosening of the rope and the rope being cut, and the emergency stop device is operated (for example, see Patent Document 1).

また一般的なエレベーターの調速機として、調速機ロープの速度からかごの速度を検出し、かごの速度がある一定以上に達すると調速機が調速機ロープを停止し、調速機ロープで非常止め装置作動スイッチを動作させて、非常止め装置を動作させるものもあった。またダブルデッキエレベーター装置としては上かご及び下かごを駆動する場合にロープを用いないものなども存在した。   As a general elevator speed governor, the speed of the car is detected from the speed of the speed governor rope, and when the speed of the car reaches a certain level, the speed governor stops the speed governor rope. Some have operated an emergency stop device by operating an emergency stop device operation switch with a rope. Some double deck elevator devices do not use ropes when driving the upper and lower cars.

以下、本発明に係るダブルデッキエレベーター装置の実施例について、図面を用いながら詳しく説明する。   Hereinafter, embodiments of a double deck elevator apparatus according to the present invention will be described in detail with reference to the drawings.

図１は本発明のダブルデッキエレベーター装置全体の概略構成図である。本実施形態に係るダブルデッキエレベーター装置は、図１に示すように、昇降路１内を昇降するかご枠２と、一端がかご枠２に連結される主索３と、主索３の他端に連結され、昇降路１内を昇降するつり合いおもり４と、昇降路１上部の機械室５に設置されるとともに、主索３が巻き掛けられ、主索３を駆動する駆動装置６と、機械室５にあって駆動装置６の近傍に配置され、主索３が巻き掛けられるそらせ車７と、機械室５に配置され、ダブルデッキエレベーターの運転を制御する制御装置８とを有している。なお、制御装置８は駆動装置６とケーブル９を介して接続されている。   FIG. 1 is a schematic configuration diagram of the entire double deck elevator apparatus of the present invention. As shown in FIG. 1, the double deck elevator apparatus according to the present embodiment includes a car frame 2 that moves up and down in the hoistway 1, a main rope 3 that has one end connected to the car frame 2, and the other end of the main rope 3. And a counterweight 4 that moves up and down in the hoistway 1, is installed in a machine room 5 above the hoistway 1, the main rope 3 is wound around, and a drive device 6 that drives the main rope 3, a machine There is a deflecting wheel 7 disposed in the vicinity of the driving device 6 in the chamber 5 and around which the main rope 3 is wound, and a control device 8 disposed in the machine room 5 and controlling the operation of the double deck elevator. . The control device 8 is connected to the drive device 6 via a cable 9.

図２は本発明のダブルデッキエレベーター装置の第１の実施例を示す要部概略構成図である。かご枠２は、図２に示すように、上枠２ａ，中間枠２ｂ，下枠２ｃ、及び左右一対の縦枠２ｄからなるとともに、その四隅に配置されたガイド部材１０を介して昇降路１に立設されたかご枠ガイドレール１１により昇降路内での昇降が案内される。また、かご枠２には、かご枠２内を互いに上下反対方向に移動可能な上かご１２及び下かご１３と、上かご１２及び下かご１３の移動を案内するガイドレール１４と、上かご１２及び下かご１３を駆動するかご駆動装置１５とが設けられている。   FIG. 2 is a schematic diagram showing the main part of a first embodiment of the double deck elevator apparatus according to the present invention. As shown in FIG. 2, the car frame 2 includes an upper frame 2 a, an intermediate frame 2 b, a lower frame 2 c, and a pair of left and right vertical frames 2 d, and a hoistway 1 through guide members 10 arranged at four corners thereof. Ascending and descending in the hoistway is guided by the car frame guide rail 11 erected on the side. Further, the car frame 2 includes an upper car 12 and a lower car 13 that can move in opposite directions in the car frame 2, a guide rail 14 that guides the movement of the upper car 12 and the lower car 13, and the upper car 12. And a car driving device 15 for driving the lower car 13.

かご駆動装置１５は、例えばモータ１５１と、上かご１２及び下かご１３の下部に各々複数個備えられるプーリ１５２と、モータ１５１のシーブ１５１ａ、及びプーリ１５２に掛け渡されるとともに、一端が上枠２ａに固定されるとともに、他端が中間枠２ｂに固定される複数のロープ１５３とを備えている。つまりロープ１５３は一端が上枠２ａに固定され、上かごのプーリ１５２に巻き掛けられて上かご１２を吊持し、その後シーブ１５１ａに巻き掛けられて下かごのプーリ１５２に巻き掛けられて下かご１３を吊持し、他端が中間枠２ｂに固定される。このような構成により、モータ１５１を駆動するとシーブ１５１ａが回転し、ロープ１５３が駆動され、上かご１２及び下かご１３はかご枠２内を互いに上下反対方向に昇降することとなる。   The car driving device 15 is spanned over, for example, a motor 151, a plurality of pulleys 152 provided respectively below the upper car 12 and the lower car 13, a sheave 151 a and a pulley 152 of the motor 151, and one end of the car driving device 15. And a plurality of ropes 153 whose other ends are fixed to the intermediate frame 2b. That is, one end of the rope 153 is fixed to the upper frame 2a and is wound around the pulley 152 of the upper car to suspend the upper car 12, and is then wound around the sheave 151a and is wound around the pulley 152 of the lower car. The car 13 is suspended and the other end is fixed to the intermediate frame 2b. With such a configuration, when the motor 151 is driven, the sheave 151a is rotated, the rope 153 is driven, and the upper car 12 and the lower car 13 are moved up and down in the car frame 2 in opposite directions.

さらに本実施形態におけるダブルデッキエレベーター装置は、かご枠内２に、上かごの移動と共に動く上かご調速機ロープ１８ａと、上かご調速機ロープ１８ａが巻き掛けられた上かご調速機ローププーリである調速機１６ａ及びその下方に配置された調速機テンションプーリ１７ａとからなる上かご調速機構を備えている。調速機１６ａとしては一般的な調速機が使用できる。そして、調速機１６ａのプーリと調速機テンションプーリ１７ａの間、即ち上かご調速機ローププーリ間に上かご調速機ロープ１８ａが架け渡されて、調速機ロープ１８ａの両端は非常止め装置連結部材１９ａに連結することで、無端状に設置されて上かご１２の動きを調速機１６ａに伝達している。   Furthermore, the double deck elevator apparatus according to the present embodiment includes an upper car governor rope 18a that moves with the movement of the upper car, and an upper car governor rope pulley that is wound around the upper car governor rope 18a. And a governor tension pulley 17a disposed below the governor 16a. A general governor can be used as the governor 16a. The upper cage governor rope 18a is bridged between the pulley of the governor 16a and the governor tension pulley 17a, that is, between the upper cage governor rope pulley, and both ends of the governor rope 18a are emergency-stopped. By connecting to the device connecting member 19a, it is installed endlessly and transmits the movement of the upper car 12 to the governor 16a.

また上かご１２には、上かご非常止め装置２２ａが設けられている。そして本実施形態では上かご非常止め装置２２ａの作動スイッチを非常止め装置連結部材１９ａが兼ねている。なお、図２には上かご１２には左右両側に上かご非常止め装置２２ａが備えられており、作動スイッチである非常止め装置連結部材１９ａが作動するとこの左右両方の上かご非常止め装置２２ａが作動する。   The upper car 12 is provided with an upper car safety device 22a. In this embodiment, the emergency stop device connecting member 19a also serves as an operation switch of the upper car safety device 22a. In FIG. 2, the upper car 12 is provided with upper car emergency stop devices 22a on both the left and right sides. When the emergency stop device connecting member 19a, which is an operation switch, is actuated, both the left and right upper car emergency stop devices 22a are provided. Operate.

このような構成により、上かご調速機ロープ１８ａと上かご１２の相対移動量に大きな差が出てくると、上かご調速機ロープ１８ａに上かご非常止め装置２２ａの作動スイッチである非常止め装置連結部材１９ａが連結されているので、上かご非常止め装置２２ａが作動する。本実施形態における上かご非常止め装置２２ａはかご枠内に設置されたガイドレール１４を掴んで上かご１２の動きを止める構成となっている。   With this configuration, when there is a large difference in the relative movement amount between the upper car governor rope 18a and the upper car 12, an emergency switch that is an operation switch of the upper car emergency stop device 22a is provided on the upper car governor rope 18a. Since the stop device connecting member 19a is connected, the upper car emergency stop device 22a operates. The upper car emergency stop device 22a in the present embodiment is configured to stop the movement of the upper car 12 by grasping the guide rail 14 installed in the car frame.

そして本実施形態では、上かご調速機ロープ１８ａに慣性質量２０ａが付加されている。このような構成により、例えば何らかの異常発生時、所定以上の速度で上かご１２が動作した場合には調速機１６ａが上かご調速機ロープ１８ａをつかみ、上かご調速機ロープ１８ａの動きを停止させて相対的に上かご１２が動作することで上かご非常止め装置連結部材１９ａを引き上げられて上かご非常止め装置２２ａが作動し、上かご１２の動きを停止させる。また、例えばロープ１５３が切断され上かご１２が落下した場合では、上かご１２に連結された非常止め装置連結部材１９ａは、調速機ロープ１８ａを引き下げようとする。すると上かご調速機ロープ１８ａはかご調速機ローププーリを介し調速機ロープ１８ａに付加した慣性質量２０ａを引き上げようとすることになる。しかし、慣性質量２０ａが付与された上かご調速機ロープ１８ａはある一定の加速度より小さな加速度で上かご１２が動作しようとしたときには上かご１２の動きと一緒に動くことが可能であるが、上かご１２がある一定の加速度以上の加速度で動こうとすると、調速機ロープ１８ａに大きなテンションが加わり非常止め装置連結部材１９ａを動作させ非常止め装置を動作させる。   In this embodiment, an inertia mass 20a is added to the upper car governor rope 18a. With such a configuration, for example, when an abnormality occurs, when the upper car 12 operates at a speed higher than a predetermined speed, the governor 16a grasps the upper car governor rope 18a, and the upper car governor rope 18a moves. The upper car emergency stop device connecting member 19a is pulled up by the relative movement of the upper car 12 and the upper car emergency stop device 22a is actuated to stop the movement of the upper car 12. Further, for example, when the rope 153 is cut and the upper car 12 is dropped, the emergency stop device connecting member 19a connected to the upper car 12 tries to pull down the governor rope 18a. Then, the upper car governor rope 18a tries to pull up the inertial mass 20a added to the governor rope 18a via the car governor rope pulley. However, the upper car speed governor rope 18a provided with the inertial mass 20a can move together with the movement of the upper car 12 when the upper car 12 tries to operate at an acceleration smaller than a certain acceleration. When the upper car 12 tries to move at an acceleration higher than a certain acceleration, a large tension is applied to the governor rope 18a, and the emergency stop device connecting member 19a is operated to operate the emergency stop device.

このように上かご調速機構には、上かご調速機ロープ１８ａが所定の加速度以上で上かご１２が昇降した際に、上かご非常止め装置２２ａの作動スイッチである上かご非常止め装置連結部材１９ａを駆動して上かご非常止め装置２２ａを作動させるための慣性力付与手段としての慣性質量２０ａを備えている。そして、通常時にモータ１５１を回転させてシーブ１５１ａによってロープ１５３を駆動させる際には、上かご１２を所定の加速度以下で駆動させるので上かご非常停止装置２２ａを作動させてしまうことはない。そして、上かごのロープ切れなどの異常が発生した場合などの一定の加速度以上で上かご１２が動作した際には応答性よく上かご非常停止装置２２ａが作動される。   In this way, the upper car speed control mechanism is connected to the upper car emergency stop device which is an operation switch of the upper car emergency stop device 22a when the upper car governor rope 18a moves up and down at a predetermined acceleration or higher. An inertial mass 20a is provided as an inertial force applying means for driving the member 19a to operate the upper car safety device 22a. When the motor 151 is rotated during normal operation and the rope 153 is driven by the sheave 151a, the upper car 12 is driven at a predetermined acceleration or less, so that the upper car emergency stop device 22a is not operated. When the upper car 12 is operated at a certain acceleration or higher, such as when an abnormality such as a rope breakage of the upper car occurs, the upper car emergency stop device 22a is operated with good responsiveness.

また本実施形態では、下かご１３においても同様の構成を有している。つまりかご枠内２に、下かご１３の移動と共に動く下かご調速機ロープ１８ｂと、下かご調速機ロープ１８ｂが巻き掛けられた下かご調速機ローププーリである調速機１６ｂ及びその下方に配置された調速機テンションプーリ１７ｂとからなる下かご調速機構を備えている。また下かご１３にも、下かご非常止め装置２２ｂが設けられていて、下かご非常止め装置２２ｂの作動スイッチも非常止め装置連結部材１９ｂが兼ねている。なお、調速機１６ｂとしては上かご１２にて説明した調速機１６ａと同様のものを用いており、下かご調速機構及び下かご非常止め装置２２ｂも上かご調速機構及び上かご非常止め装置２２ａで説明したのと同様に動作するものである。   In the present embodiment, the lower car 13 has the same configuration. That is, in the car frame 2, a lower car governor rope 18 b that moves as the lower car 13 moves, a speed governor 16 b that is a lower car governor rope pulley around which the lower car governor rope 18 b is wound, and the lower part thereof. And a governor tension pulley 17b disposed in the lower part of the car. Also, the lower car safety device 22b is provided in the lower car 13, and the operation switch of the lower car safety device 22b is also used as the safety device connecting member 19b. The speed governor 16b is the same as the speed governor 16a described in the upper car 12, and the lower car speed control mechanism and the lower car emergency stop device 22b are also used for the upper car speed control mechanism and the upper car emergency. The operation is the same as described in the stopper device 22a.

そして、下かご調速機ロープ１８ｂに慣性質量２０ｂが付加されているため、何らかの異常発生時に所定以上の速度で下かご１３が動作した場合には調速機１６ｂが下かご調速機ロープ１８ｂをつかみ下かご調速機ロープ１８ｂの動きを停止させて、相対的に下かご１３が動作することで下かご非常止め装置連結部材１９ｂが引き上げられて下かご非常止め装置２２ｂが作動し、下かご１３の動きを停止させる。また、例えばロープ１５３が切断され下かご１３が落下した場合では、慣性質量２０ｂが付与された下かご調速機ロープ１８ｂはある一定の加速度より小さな加速度で下かご１３が動作しようとしたときには下かご１３の動きと一緒に動くことが可能であるが、下かご１３がある一定の加速度以上の加速度で動こうとすると、調速機ロープ１８ｂに大きなテンションが加わり非常止め装置連結部材１９ｂを動作させ非常止め装置２２ｂを動作させる。   Since the inertia mass 20b is added to the lower car governor rope 18b, when the lower car 13 operates at a speed higher than a predetermined speed when some abnormality occurs, the governor 16b becomes the lower car governor rope 18b. The lower car speed governor rope 18b is stopped and the lower car 13 is relatively operated, whereby the lower car emergency stop device connecting member 19b is pulled up, and the lower car emergency stop device 22b is operated. The movement of the car 13 is stopped. For example, when the rope 153 is cut and the lower car 13 is dropped, the lower car governor rope 18b to which the inertial mass 20b is applied is lowered when the lower car 13 tries to operate at an acceleration smaller than a certain acceleration. Although it is possible to move together with the movement of the car 13, if the lower car 13 tries to move at an acceleration exceeding a certain acceleration, a large tension is applied to the governor rope 18b to operate the emergency stop device connecting member 19b. The emergency stop device 22b is operated.

このように下かご調速機構にも、所定の加速度以上で下かご１３が昇降した際に、下かご非常止め装置２２ｂの作動スイッチである下かご非常止め装置連結部材１９ｂを駆動して下かご非常止め装置２２ｂを作動させるための慣性力付与手段としての慣性質量２０ｂを下かご調速機ロープ１８ｂに備えている。そして、通常時にモータ１５１を回転させてシーブ１５１ａによってロープ１５３を駆動させる際には、下かご１３を所定の加速度以下で駆動させるので下かご非常停止装置２２ｂを作動させてしまうことはない。そして、下かごのロープ切れなどの異常が発生した一定の加速度以上で下かご１３が動作した際には応答性よく下かご非常停止装置２２ｂが作動される。   In this manner, the lower car speed control mechanism also drives the lower car emergency stop device connecting member 19b, which is an operation switch of the lower car emergency stop device 22b, when the lower car 13 moves up and down at a predetermined acceleration or higher. The lower cage governor rope 18b is provided with an inertial mass 20b as inertial force applying means for operating the emergency stop device 22b. When the rope 151 is driven by the sheave 151a by rotating the motor 151 in the normal state, the lower car emergency stop device 22b is not operated because the lower car 13 is driven at a predetermined acceleration or less. When the lower car 13 is operated at a certain acceleration or higher where an abnormality such as a rope breakage of the lower car has occurred, the lower car emergency stop device 22b is operated with good responsiveness.

なお、本実施形態においてはかご枠２内の上かご１２及び下かご１３の両者に上かご調速機構，下かご調速機構及び上かご非常止め装置２２ａ，下かご非常止め装置２２ｂを設ける例を挙げて説明した。このように上かご１２及び下かご１３の両者設けると、両かごの安全性が向上される。特に本実施例のように、上かご１２及び下かご１３の駆動をロープ１５３で行うようにした場合、例えばロープ切れ等が発生した場合には上かご１２及び下かご１３の両者が落下するため、このように上かご１２及び下かご１３の両者に上かご調速機構，下かご調速機構及び上かご非常止め装置２２ａ，下かご非常止め装置２２ｂを設けると良好である。   In this embodiment, the upper car speed adjusting mechanism, the lower car speed adjusting mechanism, the upper car emergency stop device 22a, and the lower car emergency stop device 22b are provided in both the upper car 12 and the lower car 13 in the car frame 2. And explained. If both the upper car 12 and the lower car 13 are provided in this way, the safety of both cars is improved. In particular, as in this embodiment, when the upper car 12 and the lower car 13 are driven by the rope 153, for example, when the rope breakage occurs, both the upper car 12 and the lower car 13 fall. Thus, it is preferable to provide the upper car speed control mechanism, the lower car speed control mechanism, the upper car emergency stop device 22a, and the lower car emergency stop device 22b in both the upper car 12 and the lower car 13.

しかし、上かご１２及び下かご１３を駆動する方法はロープを用いるものに限られるものではないので、例えば、上かご１２又は下かご１３のどちらか一方の落下の可能性が著しく小さい又は無い場合には、落下の可能性がある一方のかごのみに、上かご調速機構または下かご調速機構及び上かご非常止め装置２２ａ又は下かご非常止め装置２２ｂを設けるようにしてもよい。このように構成することでかご枠２の構造の簡易化が図れると共に、重量等も軽量化が図れ、製造コストや製造効率，運転効率などが向上できる。   However, since the method of driving the upper car 12 and the lower car 13 is not limited to that using a rope, for example, when the possibility of dropping either the upper car 12 or the lower car 13 is extremely small or not Alternatively, the upper car speed adjusting mechanism or the lower car speed adjusting mechanism and the upper car emergency stop device 22a or the lower car emergency stop device 22b may be provided only in one of the cars that may be dropped. With this configuration, the structure of the car frame 2 can be simplified, the weight and the like can be reduced, and the manufacturing cost, manufacturing efficiency, operating efficiency, and the like can be improved.

続いて本発明の他の実施形態について説明する。なお、本実施例において実施例１と同様の構成要素については同一の符号を付して説明を省略する。図３は本発明のダブルデッキエレベーター装置の第２の実施例を示す要部概略構成図である。第２の実施例におけるダブルデッキエレベーター装置は、慣性力付与手段としての回転慣性質量２１ａ，２１ｂが調速機テンションプーリ１７ａ，１７ｂに設けられている。   Next, another embodiment of the present invention will be described. In addition, in a present Example, about the component similar to Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted. FIG. 3 is a schematic diagram showing the main part of a second embodiment of the double deck elevator apparatus according to the present invention. In the double deck elevator apparatus according to the second embodiment, rotational inertia masses 21a and 21b as inertial force applying means are provided on the governor tension pulleys 17a and 17b.

つまり、上かご１２又は下かご１３に連結された非常止め装置連結部材１９ａ，１９ｂは、調速機ロープ１８ａ，１８ｂを引き下げようとする。それに伴って調速機ロープ１８ａ，１８ｂは、調速機１６ａ，１６ｂを介し調速機テンションプーリ１７ａ，１７ｂを回転させようとする。この時、調速機テンションプーリ１７ａ，１７ｂに付加した回転慣性質量により、上かご調速機ロープ１８ａ又は下かご調速機ロープ１８ｂが所定の加速度以上で上かご１２または下かご１３が昇降した際に慣性力が生じ調速機ロープ１８ａ，１８ｂにテンションが加わり、上かご非常止め装置２２ａ又は下かご非常止め装置２２ｂの作動スイッチである非常止め装置連結部材１９ａ，１９ｂを動作させて上かご非常止め装置２２ａ又は下かご非常止め装置２２ｂを動作させる。この回転慣性質量は調速機本体１６ａ，１６ｂの回転体に付加されても同様の効果を生む。   That is, the emergency stop device connecting members 19a and 19b connected to the upper car 12 or the lower car 13 try to pull down the governor ropes 18a and 18b. Accordingly, the governor ropes 18a and 18b attempt to rotate the governor tension pulleys 17a and 17b via the governors 16a and 16b. At this time, due to the rotational inertial mass added to the governor tension pulleys 17a and 17b, the upper car governor rope 18a or the lower car governor rope 18b moves up and down at a predetermined acceleration or higher. In this case, an inertial force is generated and tension is applied to the governor ropes 18a and 18b, and the upper cage is operated by operating the emergency stop device connecting members 19a and 19b which are operation switches of the upper cage emergency stop device 22a or the lower cage emergency stop device 22b. The safety device 22a or the lower cage safety device 22b is operated. Even if this rotational inertial mass is added to the rotating bodies of the governor bodies 16a and 16b, the same effect is produced.

このように慣性力付与手段としては、かご枠２の構造や要求される性能や大きさなどにより適宜選択して使用することができる。   As described above, the inertial force applying means can be appropriately selected and used depending on the structure of the car frame 2 and the required performance and size.

以上説明したように、本発明はかご枠内を互いに上下反対方向に移動可能な上かご及び下かごに設置される調速機ロープに慣性質量、又は調速機回転体もしくは調速機テンションプーリに回転慣性質量を付加する構成により、上かご及び下かごを駆動するロープ切れ時に生じる通常のエレベーター加速度を超えたかご落下の加速度に応じて発生する慣性力により非常止め装置を高応答で動作させることができる。   As described above, the present invention has an inertial mass, or a governor rotor or governor tension pulley on a governor rope installed in an upper car and a lower car that can move in the opposite directions in the car frame. By adding rotational inertial mass to the car, the emergency stop device is operated with high response by the inertial force generated according to the acceleration of the car falling over the normal elevator acceleration that occurs when the rope driving the upper and lower cars is broken. be able to.

このように構成した本発明では、何らかの理由によりロープが切断されかごに落下の加速度が発生すると、調速機ロープに付加した慣性質量、又は調速機回転体もしくは調速機のテンションプーリに付加した回転慣性質量の効果によりかごの非常止め装置に連結された調速機ロープに慣性力が加わり非常止め装置を動作することができる。   In the present invention configured as described above, when the rope is cut for some reason and the fall acceleration occurs in the cage, the inertia mass added to the governor rope, or the governor rotating body or the tension pulley of the governor is added. Due to the effect of the rotating inertial mass, the inertial force is applied to the governor rope connected to the car safety device, and the safety device can be operated.

また、本発明は、かごの落下の加速度を検知するため、調速機が動作前であっても調速機ロープに慣性力が加わることで非常止め装置を動作することができる。また、上かご及び下かごを駆動するロープ切れ時のかご落下を確実に検出できる。   Moreover, since the present invention detects the acceleration of the fall of the car, the emergency stop device can be operated by applying an inertial force to the governor rope even before the governor is in operation. In addition, it is possible to reliably detect the car falling when the rope driving the upper car and the lower car is broken.
