エレベータ装置  Elevator equipment
技術分野  Technical field
[0001] この発明は、複数の卷上機により 1台のかごを昇降させるエレベータ装置に関する ものである。  [0001] The present invention relates to an elevator apparatus that raises and lowers one car by a plurality of lifting machines.
背景技術  Background art
[0002] 近年、建物の高層化に伴い、より多くの乗客をより早く移動させることができるエレ ベータが求められている。これに対し、力ごを大型化する方法がある力 そのために は、大トルク'大出力の大型の卷上機が必要となり、製作費用及び揚重 '据付費用等 が高くなる。  In recent years, with an increase in the number of buildings, there is a demand for an elevator that can move more passengers faster. On the other hand, there is a way to increase the size of the force. For this purpose, a large lifting machine with large torque and high output is required, which increases the production cost and the lifting and installation cost.
[0003] また、卷上機を大型化せず、 2台の卷上機で 1台のかごを昇降させるエレベータ装 置が提案されている。このエレベータ装置では、かご及び釣合おもりにそれぞれ動滑 車を設けることにより、 2台の卷上機に生じる速度差による不具合が解消されている（ 例えば、特許文献 1参照)。  [0003] Further, there has been proposed an elevator apparatus that raises and lowers one car with two hoisting machines without increasing the size of the hoisting machine. In this elevator apparatus, by providing a movable pulley for each of the car and the counterweight, the problem due to the speed difference that occurs in the two hoisting machines is eliminated (see, for example, Patent Document 1).

発明が解決しょうとする課題  Problems to be solved by the invention
[0005] 上記のような従来のエレベータ装置では、かご及び釣合おもりに動滑車を設けたの で、主ロープとしてエンドレスロープが必要となる。し力し、エンドレスロープは 1本の ロープの両端部を互いに接続して製作されるため、つなぎ目の段差を無くすのが難 しい。また、 2台の卷上機に設けられたブレーキの動作タイミングや制動力に個体差 があるため、非常停止時に 2つの駆動シーブの主ロープの走行距離の差が大きくな り、ロープ位置が移動してつなぎ目が駆動シーブや動滑車を通過し、かごに振動が 発生してしまう可能性があった。 [0005] In the conventional elevator apparatus as described above, since a movable pulley is provided for the car and the counterweight, an endless rope is required as a main rope. However, since endless ropes are manufactured by connecting both ends of a single rope, it is difficult to eliminate the step difference at the joint. Also, because there are individual differences in the operation timing and braking force of the brakes installed on the two hoisting machines, the difference in the distance traveled by the main ropes of the two drive sheaves during an emergency stop increases and the rope position moves. As a result, the joint could pass through the drive sheave or the moving pulley, causing vibrations in the car.
[0006] この発明は、上記のような課題を解決するためになされたものであり、複数の卷上 機を用いつつ、非常制動時でもロープ位置の移動が小さぐ安定的に停止できるェ レベータ装置を得ることを目的とする。 課題を解決するための手段 [0006] The present invention has been made to solve the above-described problems, and is an elevator that can be stably stopped with a small movement of the rope position even during emergency braking while using a plurality of lifting machines.

[0009] 以下、この発明を実施するための最良の形態について、図面を参照して説明する。 Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
実施の形態 1.  Embodiment 1.
図 1はこの発明の実施の形態 1によるエレベータ装置を示す斜視図である。図にお いて、昇降路 1内には、一対のかごガイドレール 2と、一対の釣合おもりガイドレール 3 とが設置されている。第 1の昇降体であるかご 4は、かごガイドレール 2に沿って昇降 路 1内を昇降される。第 2の昇降体である釣合おもり 5は、釣合おもりガイドレール 3に 沿って昇降路 1内を昇降される。  FIG. 1 is a perspective view showing an elevator apparatus according to Embodiment 1 of the present invention.

The car 4 as the first lifting body is moved up and down in the hoistway 1 along the car guide rail 2. The counterweight 5 which is the second lifting body is moved up and down in the hoistway 1 along the counterweight guide rail 3.
[0010] 釣合おもり 5は、昇降体本体である釣合おもり本体 16と、釣合おもり本体 16に揺動 可能に接続された揺動部材 (ロープ接続部材） 17と、釣合おもり本体 16と揺動部材 1 7とを接続する接続部材 18とを有している。釣合おもり本体 16は、揺動部材 17から 接続部材 18を介して吊り下げられている。  [0010] The counterweight 5 includes a counterweight main body 16 that is a lift body, a swing member (rope connection member) 17 that is swingably connected to the counterweight main body 16, and a counterweight main body 16 And a connecting member 18 for connecting the swing member 17. The counterweight body 16 is suspended from the swing member 17 via the connection member 18.
[0011] 接続部材 18の上端部は、揺動部材 17の揺動中心、即ち揺動軸 17aに回動自在に 連結されている。摇動軸 17aは、釣合おもり本体 16の厚さ方向に平行、かつ水平で ある。接続部材 18の下端部は、釣合おもり本体 16の上部の中心に接続されている。 また、接続部材 18の上端部には、揺動部材 17の揺動状態を検出する揺動検出手 段（図示せず）が設けられている。揺動検出手段としては、例えばエンコーダが用い られる。  [0011] The upper end portion of the connection member 18 is rotatably connected to the swing center of the swing member 17, that is, the swing shaft 17a. The peristaltic shaft 17a is parallel to the thickness direction of the counterweight body 16 and is horizontal. The lower end portion of the connection member 18 is connected to the center of the upper portion of the counterweight body 16. Further, a swing detecting means (not shown) for detecting the swing state of the swing member 17 is provided at the upper end portion of the connecting member 18. For example, an encoder is used as the swing detection means.
[0012] 昇降路 1の上部には、第 1及び第 2の卷上機 6, 7が配置されている。第 1の卷上機 6は、第 1の駆動シーブ 8と第 1の卷上機本体 9とを有している。第 1の卷上機本体 9 は、第 1の駆動シーブ 8を回転させる第 1の電動機と、第 1の駆動シーブ 8の回転を制 動する第 1の卷上機ブレーキとを含んでいる。  [0012] In the upper part of the hoistway 1, first and second lifting machines 6, 7 are arranged. The first lifting machine 6 has a first driving sheave 8 and a first lifting machine body 9. The first lifting machine body 9 includes a first electric motor that rotates the first drive sheave 8 and a first lifting machine brake that controls the rotation of the first drive sheave 8.
[0013] 第 2の卷上機 7は、第 2の駆動シーブ 10と第 2の卷上機本体 11とを有している。第 2 の卷上機本体 11は、第 2の駆動シーブ 10を回転させる第 2の電動機と、第 2の駆動 シーブ 10の回転を制動する第 2の卷上機ブレーキとを含んでいる。また、第 1及び第 2の卷上機 6, 7は、駆動シーブ 8, 10の回転軸が水平となるように配置されている。 The second lifting machine 7 has a second drive sheave 10 and a second lifting machine body 11. The second hoisting machine main body 11 includes a second electric motor for rotating the second drive sheave 10 and a second drive. Includes a second lifting brake that brakes the rotation of the sheave 10. The first and second lifting machines 6 and 7 are arranged so that the rotation shafts of the drive sheaves 8 and 10 are horizontal.
[0014] 第 1及び第 2の駆動シーブ 8, 10には、少なくとも 1本の主ロープ 12が巻き掛けられ ている。力ご 4及び釣合おもり 5は、主ロープ 12により昇降路 1内に吊り下げられ、第 1及び第 2の卷上機 6, 7の駆動力により昇降路 1内を昇降される。釣合おもり 5は、か ご 4とは逆方向に昇降される。  [0014] At least one main rope 12 is wound around the first and second drive sheaves 8, 10. The force 4 and the counterweight 5 are suspended in the hoistway 1 by the main rope 12, and are raised and lowered in the hoistway 1 by the driving force of the first and second lifting machines 6, 7. The counterweight 5 is raised and lowered in the opposite direction to the car 4.
[0015] 主ロープ 12は、揺動軸 17aの一側で揺動部材 17に接続された第 1のロープ端部 1 2aと、揺動軸 17aの他側で揺動部材 17に接続された第 2のロープ端部 12bとを有し ている。第 1及び第 2のロープ端部 12a, 12bは、揺動軸 17aから等距離の位置で揺 動部材 17に接続されて!ヽる。  [0015] The main rope 12 is connected to the swing member 17 on one side of the swing shaft 17a and to the swing member 17 on the other side of the swing shaft 17a. And a second rope end 12b. The first and second rope ends 12a and 12b are connected to the swing member 17 at a position equidistant from the swing shaft 17a.
[0016] 昇降路 1の上部には、第 1のロープ端部 12a及び第 2のロープ端部 12bを釣合おも り 5に導く第 1及び第 2のそらせ車 14, 15が配置されている。第 1及び第 2のそらせ車 14, 15は、それらの回転軸が水平となるように配置されている。  In the upper part of the hoistway 1, there are arranged first and second deflecting wheels 14, 15 for guiding the first rope end 12 a and the second rope end 12 b to the counterweight 5. Yes. The first and second deflecting wheels 14 and 15 are arranged so that their rotational axes are horizontal.
[0017] かご 4の上部には、水平な回転軸を中心に回転可能なバランスプーリ 13が設けら れている。バランスプーリ 13には、主ロープ 12の中間部が巻き掛けられている。  [0017] On the upper part of the car 4, a balance pulley 13 is provided that is rotatable about a horizontal rotating shaft. An intermediate portion of the main rope 12 is wound around the balance pulley 13.
[0018] 第 1及び第 2卷上機 6, 7は、制御装置 19により制御される。制御装置 19は、揺動 検出手段からの信号に応じて、揺動部材 17の揺動を打ち消すように、即ち揺動部材 17を水平に戻すように、第 1及び第 2の卷上機 6, 7を制御する。  The first and second upper machines 6 and 7 are controlled by the control device 19. In response to a signal from the swing detection means, the control device 19 cancels the swing of the swing member 17, that is, returns the swing member 17 to the horizontal position. , 7 is controlled.
[0019] かご 4の下部には、力ご 4の速度が予め設定された過速度 (例えば定格速度の 1. 4 倍）に達したときにかご 4を非常停止させるための非常止め装置 20が搭載されている  [0019] At the bottom of the car 4, there is an emergency stop device 20 for emergency stopping the car 4 when the speed of the force car 4 reaches a preset overspeed (eg, 1.4 times the rated speed). Installed
[0020] また、かご 4には、非常止め装置 20とは異なる条件でかご 4を非常停止させるため の昇降体搭載ブレーキ装置としての一対のかご搭載ブレーキ装置 21a, 21bが搭載 されている。かご搭載ブレーキ装置 21a, 21bは、かごガイドレール 2を把持すること によりかご 4を制動する。また、力ご搭載ブレーキ装置 21a, 21bとしては、例えば電 磁ブレーキ装置が用いられる。 [0020] Further, the car 4 is mounted with a pair of car-mounted brake devices 21a and 21b as a lifting device mounted brake device for emergency-stopping the car 4 under conditions different from those of the emergency stop device 20. The car-mounted brake devices 21a and 21b brake the car 4 by gripping the car guide rail 2. Further, as the force loaded brake devices 21a and 21b, for example, electromagnetic brake devices are used.
[0021] 昇降路 1内の最上階付近及び最下階付近には、終端階減速装置及び行過制限装 置がそれぞれ設けられている。これにより、通常、昇降路 1内の最上階付近及び最下 階付近では、カゝご 4は、予め設定された速度曲線に沿って減速停止される。しかし、 何等かの原因で、かご 4の速度が速度曲線から外れた場合、制御装置 19内の安全 回路が遮断され、制御装置 19から非常停止指令が出力される。これにより、第 1及び 第 2の卷上機ブレーキとは無関係に、かご搭載ブレーキ装置 21a, 21bによって、か ご 4が強制的に非常停止される。 [0021] Near the uppermost floor and the lowermost floor in the hoistway 1, a terminal floor speed reducer and an over-limit device are provided. This usually results in the vicinity of the top floor in hoistway 1 and the bottom Near the floor, the car 4 is decelerated and stopped along a preset speed curve. However, if the speed of the car 4 deviates from the speed curve for some reason, the safety circuit in the control device 19 is shut off and an emergency stop command is output from the control device 19. Thereby, the car 4 is forcibly stopped by the car-mounted brake devices 21a and 21b irrespective of the first and second lifting machine brakes.
[0022] このようなエレベータ装置では、第 1及び第 2の卷上機 6, 7は、同期運転するよう制 御装置 19により制御されている。しかし、駆動シーブ 8, 10の製作誤差、かご 4の加 減速及び制動時等に発生する駆動シーブ 8, 10と主ロープ 12との間の微少な滑り、 及び卷上機本体 9, 11のトルク変動等により、かご 4に対して第 1の駆動シーブ 8側の 主ロープ 12の走行距離と、第 2の駆動シーブ 10側の主ロープ 12の走行距離との間 には僅かな誤差が生じる。このような僅かな走行距離の誤差は、天秤式のバランス機 構として作用する揺動部材 17の揺動 (傾き）により吸収される。  [0022] In such an elevator apparatus, the first and second hoisting machines 6, 7 are controlled by the control apparatus 19 so as to operate synchronously. However, manufacturing errors of the drive sheaves 8 and 10; slight slippage between the drive sheaves 8 and 10 and the main rope 12 that occurs during acceleration / deceleration and braking of the car 4; and the torque of the hoisting machine main bodies 9 and 11 Due to fluctuations, a slight error occurs between the traveling distance of the main rope 12 on the first drive sheave 8 side and the traveling distance of the main rope 12 on the second drive sheave 10 side with respect to the car 4. Such a slight error in travel distance is absorbed by the swinging (tilting) of the swinging member 17 acting as a balance-type balance mechanism.
[0023] しかし、非常時に卷上機ブレーキを動作させて、動作タイミングや制動力に差があ ると、駆動シーブ 8側の主ロープ 12と駆動シーブ 10側の主ロープ 12との間には、短 時間で大きな走行距離の誤差が発生し、天秤式のバランス機構では吸収しきれな ヽ 可能性がある。そこで、非常時には第 1及び第 2の卷上機ブレーキは動作させず、か ご搭載ブレーキ装置 21a, 21bのみを動作させ、かご 4を強制的に非常停止させる。 このようにすると、力ご 4が制動しても主ロープ 12とかご 4との間に昇降距離の差が出 ないので、かご 4は安定して停止できる。特に、一対のかご搭載ブレーキ装置 21a, 2 lbを機械的に連動させるようにすれば、かご搭載ブレーキ装置 21a, 21bをより確実 に同時に動作させることができる。  [0023] However, if the hoisting machine brake is operated in an emergency and there is a difference in operation timing and braking force, there is a difference between the main rope 12 on the drive sheave 8 side and the main rope 12 on the drive sheave 10 side. However, a large mileage error occurs in a short time, and the balance type balance mechanism may not be able to absorb it. Therefore, in an emergency, the first and second lifting machine brakes are not operated, but only the car-mounted brake devices 21a and 21b are operated, and the car 4 is forcibly stopped. In this way, even when the force 4 is braked, there is no difference in the lifting distance between the main rope 12 and the car 4, so the car 4 can be stably stopped. In particular, if the pair of car-mounted brake devices 21a and 2 lb are mechanically interlocked, the car-mounted brake devices 21a and 21b can be more reliably operated simultaneously.
[0024] なお、力ご搭載ブレーキ装置 21a, 21bの構成の一部を非常止め装置 20と共用し てもよい。  [0024] Note that a part of the configuration of the force-equipped brake devices 21a and 21b may be shared with the emergency stop device 20.
また、非常時には、かご搭載ブレーキ装置 21a, 21bだけでなぐ第 1及び第 2の卷 上機ブレーキを併用してもよい。この場合、かご搭載ブレーキ装置 21a, 21bが動作 して力 卷上機ブレーキを動作させるようなシーケンス回路構成とするのが好適であ る。  In an emergency, the first and second lifting machine brakes that are connected only by the car-mounted brake devices 21a and 21b may be used in combination. In this case, it is preferable to adopt a sequence circuit configuration in which the car-mounted brake devices 21a and 21b operate to operate the lifting machine brake.
また、卷上機ブレーキが無ぐかご搭載ブレーキ装置のみでシステムを構成し、通 常の各階停止時の制動もかご搭載ブレーキ装置で行うようにしてもょ ヽ。この場合、 卷上機ブレーキが無いので、部品点数が少なくなり、システムを簡素化するとともに、 低コス卜ィ匕することがでさる。 In addition, the system is composed of only the brake equipment installed in the cage without the lifting machine brake, You may also use the car-mounted brake device to stop at each floor stop. In this case, since there is no upper machine brake, the number of parts is reduced, the system is simplified, and the cost is reduced.
また、駆動する卷上機は 2台に限ったものではなぐ例えばそらせ車 14, 15の位置 にも卷上機を配置してもよい。  Further, the number of the lifting machines to be driven is not limited to two. For example, the lifting machines may be arranged at the positions of the deflecting wheels 14, 15.
[0025] 実施の形態 2.  [0025] Embodiment 2.
次に、図 2はこの発明の実施の形態 2によるエレベータ装置を示す斜視図である。 図において、釣合おもり 5には、非常止め装置 20とは異なる条件で力ご 4を非常停止 させるための昇降体搭載ブレーキ装置としての一対の釣合おもり搭載ブレーキ装置 22a, 22bが搭載されている。釣合おもり搭載ブレーキ装置 22a, 22bは、釣合おもり ガイドレール 3を把持することにより釣合おもり 5を制動し、これによりかご 4を制動する 。他の構成は、実施の形態 1と同様である。  Next, FIG. 2 is a perspective view showing an elevator apparatus according to Embodiment 2 of the present invention. In the figure, the counterweight 5 is equipped with a pair of counterweight-equipped brake devices 22a and 22b as lifting device mounted brake devices for emergency stop of the force 4 under different conditions from the emergency stop device 20. Yes. The counterweight-equipped brake devices 22a and 22b brake the counterweight 5 by gripping the counterweight guide rail 3, and thereby brake the car 4. Other configurations are the same as those in the first embodiment.
[0026] このようなエレベータ装置では、非常時には、第 1及び第 2の卷上機ブレーキとは無 関係に、釣合おもり搭載ブレーキ装置 22a, 22bによって、かご 4が強制的に非常停 止されるので、卷上機ブレーキの制動力の差によって駆動シーブ 8側の主ロープ 12 と駆動シーブ 10側の主ロープ 12との走行距離差が大きくなるのが防止される。即ち 、卷上機ブレーキとは無関係に停止距離をより安定的に制御することができる。特に 、一対の釣合おもり搭載ブレーキ装置 22a, 22bを機械的に連動させるようにすれば 、釣合おもり搭載ブレーキ装置 22a, 22bをより確実に同時に動作させることができる また、釣合おもり搭載ブレーキ装置 22a, 22bを用いることにより、非常制動動作に よる振動や騒音がかご 4内に伝わりに《なる。  [0026] In such an elevator device, in an emergency, the car 4 is forcibly stopped by the counterweight-equipped brake devices 22a and 22b independently of the first and second lifting machine brakes. Therefore, the difference in the travel distance between the main rope 12 on the drive sheave 8 side and the main rope 12 on the drive sheave 10 side is prevented from increasing due to the difference in the braking force of the hoisting machine brake. That is, the stopping distance can be controlled more stably regardless of the lifting machine brake. In particular, if the pair of counterweight-equipped brake devices 22a and 22b are mechanically linked, the counterweight-equipped brake devices 22a and 22b can be operated more reliably at the same time. By using the devices 22a and 22b, vibration and noise due to the emergency braking operation are transmitted to the car 4.
[0027] 実施の形態 3. [0027] Embodiment 3.
次に、図 3はこの発明の実施の形態 3によるエレベータ装置を示す斜視図である。 この例では、ノ ランスプーリ及び揺動部材を用いず、単純な 1 : 1ロービング方式によ りかご 4及び釣合おもり 5が吊り下げられている。即ち、第 1のロープ端部 12aはかご 4 の上部に接続され、第 2のロープ端部 12bは釣合おもり 5の上部に接続されて!、る。  Next, FIG. 3 is a perspective view showing an elevator apparatus according to Embodiment 3 of the present invention. In this example, the cage 4 and the counterweight 5 are suspended by a simple 1: 1 roving method without using a pulley and a swing member. That is, the first rope end 12a is connected to the top of the car 4 and the second rope end 12b is connected to the top of the counterweight 5.
[0028] また、主ロープ 12が第 1及び第 2の駆動シーブ 8, 10を連続して通過するように、第 1及び第 2の卷上機 6, 7が並べて配置されている。即ち、第 1及び第 2の駆動シーブ 8, 10は、半径方向に互いにずらして配置されている。 [0028] In addition, the main rope 12 passes through the first and second drive sheaves 8, 10 in succession so that the first rope The first and second lifting machines 6, 7 are arranged side by side. That is, the first and second drive sheaves 8 and 10 are arranged so as to be shifted from each other in the radial direction.
[0029] 昇降路 1の上部 (機械室又は昇降路内）には、主ロープ 12に制動力を付与すること によりかご 4を非常停止させるためのロープブレーキ装置 23が設置されている。ロー プブレーキ装置 23は、全ての主ロープ 12を同時に把持することにより主ロープ 12の 移動を制動し、これによりかご 4を制動する。  [0029] In the upper part of the hoistway 1 (in the machine room or hoistway), a rope brake device 23 is installed for emergency stop of the car 4 by applying a braking force to the main rope 12. The rope brake device 23 brakes the movement of the main rope 12 by gripping all the main ropes 12 at the same time, thereby braking the car 4.
[0030] このようなエレベータ装置では、非常時には、第 1及び第 2の卷上機ブレーキとは無 関係に、ロープブレーキ装置 23によって、かご 4が強制的に非常停止されるので、卷 上機ブレーキの制動力の差によって駆動シーブ 8側の主ロープ 12と駆動シーブ 10 側の主ロープ 12との走行距離差が大きくなるのが防止される。即ち、卷上機ブレー キとは無関係に停止距離をより安定的に制御することができる。  [0030] In such an elevator apparatus, in an emergency, the car 4 is forcibly stopped by the rope brake device 23 regardless of the first and second lifting machine brakes. The difference in the braking force of the brake prevents the difference in travel distance between the main rope 12 on the drive sheave 8 side and the main rope 12 on the drive sheave 10 side. That is, the stopping distance can be controlled more stably regardless of the lifting machine brake.
また、非常制動時には、主ロープ 12が把持されるので、万一卷上機 6, 7が停止さ れなくても、駆動シーブ 8, 10は主ロープ 12に対して空転することになり、かご 4をより 確実に停止させることができる。  Also, since the main rope 12 is gripped during emergency braking, the drive sheaves 8 and 10 will idle relative to the main rope 12 even if the upper gears 6 and 7 are not stopped. 4 can be stopped more reliably.
[0031] 実施の形態 4.  [0031] Embodiment 4.
次に、図 4はこの発明の実施の形態 4によるエレベータ装置を示す斜視図である。 この例では、 2 : 1ロービング方式によりかご 4及び釣合おもり 5が吊り下げられている。 即ち、かご 4の下部には、一対のかご吊り車 24a, 24bが搭載されている。釣合おもり 5の上部には、釣合おもり吊り車 25が搭載されている。第 1及び第 2のロープ端部 12 a, 12bは、昇降路 1の上部に接続されている。主ロープ 12は、第 1のロープ端部 12a 側から順に、力ご吊り車 24a, 24b、第 2の駆動シーブ 10、第 1の駆動シーブ 8及び 釣合おもり吊り車 25に巻き掛けられている。他の構成は、実施の形態 3と同様である  Next, FIG. 4 is a perspective view showing an elevator apparatus according to Embodiment 4 of the present invention. In this example, the car 4 and the counterweight 5 are suspended by the 2: 1 roving method. That is, a pair of car suspension wheels 24a and 24b are mounted on the lower part of the car 4. On the top of the counterweight 5, a counterweight suspension vehicle 25 is mounted. The first and second rope ends 12 a and 12 b are connected to the upper part of the hoistway 1. The main rope 12 is wound around a force suspension wheel 24a, 24b, a second drive sheave 10, a first drive sheave 8, and a counterweight suspension wheel 25 in order from the first rope end 12a side. . Other configurations are the same as those in the third embodiment.
[0032] このように、 2 : 1ロービング方式のエレベータ装置であっても、非常時には、第 1及 び第 2の卷上機ブレーキとは無関係に、ロープブレーキ装置 23によって、力ご 4が強 制的に非常停止されるので、卷上機ブレーキの制動力の差によって駆動シーブ 8側 の主ロープ 12と駆動シーブ 10側の主ロープ 12との走行距離差が大きくなるのが防 止される。即ち、卷上機ブレーキとは無関係に停止距離をより安定的に制御すること ができる。 [0032] In this way, even in the case of an elevator device of 2: 1 roving system, the force 4 is strengthened by the rope brake device 23 regardless of the first and second lifting machine brakes in an emergency. Because the emergency stop is forcedly stopped, the difference in travel distance between the main rope 12 on the drive sheave 8 side and the main rope 12 on the drive sheave 10 side is prevented from increasing due to the difference in the braking force of the lifting machine brake. . In other words, the stopping distance can be controlled more stably regardless of the lifting machine brake. Can do.
[0033] なお、非常時には、ロープブレーキ装置 23だけでなぐ第 1及び第 2の卷上機ブレ ーキを併用してもよい。この場合、ロープブレーキ装置 23が動作してから卷上機ブレ ーキを動作させるようなシーケンス回路構成とするのが好適である。  [0033] In an emergency, the first and second hoisting machine brakes connected only by the rope brake device 23 may be used in combination. In this case, it is preferable to adopt a sequence circuit configuration in which the hoisting machine brake is operated after the rope brake device 23 is operated.
[0034] 実施の形態 5.  [0034] Embodiment 5.
次に、図 5はこの発明の実施の形態 5によるエレベータ装置を示す斜視図である。 第 1の卷上機 6には、 2個の第 1の卷上機ブレーキ 26, 27が設けられている。第 2の 卷上機 7には、 2個の第 2の卷上機ブレーキ 28, 29が設けられている。  Next, FIG. 5 is a perspective view showing an elevator apparatus according to Embodiment 5 of the present invention. The first hoisting machine 6 is provided with two first hoisting machine brakes 26 and 27. The second lifting machine 7 is provided with two second lifting machine brakes 28 and 29.
[0035] 図 6は図 5の卷上機ブレーキ 26〜29の配線図である。卷上機ブレーキ 26〜29は 、ブレーキコイル 26a, 27a, 28a, 29aへの通電により制動力を解除し、ブレーキコィ ル 26a, 27a, 28a, 29aへの通電の遮断により制動力を発生する電磁ブレーキであ る。また、卷上機ブレーキ 26〜29には、ブレーキコイル 26a, 27a, 28a, 29aへの通 電状態の監視を行う通電監視部（通電監視回路） 26b, 27b, 28b, 29bが設けられ ている。  FIG. 6 is a wiring diagram of the hoisting machine brakes 26 to 29 of FIG. The top brakes 26-29 are electromagnetic brakes that release the braking force by energizing the brake coils 26a, 27a, 28a, 29a and generate the braking force by interrupting the energization of the brake coils 26a, 27a, 28a, 29a. It is. In addition, the hoisting machine brakes 26-29 are provided with energization monitoring units (energization monitoring circuits) 26b, 27b, 28b, 29b that monitor the energization state of the brake coils 26a, 27a, 28a, 29a. .
[0036] さらに、卷上機ブレーキ 26〜29には、ブレーキシュ一の動作位置を監視する動作 監視部（動作監視回路） 26c, 27c, 28c, 29cが設けられている。動作監視部 26c, 27c, 28c, 29cには、ブレーキシュ一が制動動作することにより開放されるマイクロス イッチが設けられている。  [0036] Furthermore, the hoisting machine brakes 26 to 29 are provided with operation monitoring units (operation monitoring circuits) 26c, 27c, 28c, and 29c for monitoring the operation position of the brake shoe. The operation monitoring units 26c, 27c, 28c, and 29c are provided with micro switches that are opened when the brake shoe performs a braking operation.
[0037] 全ての通電監視部 26b, 27b, 28b, 29b及び全ての動作監視部 26c, 27c, 28c, 29cは、ブレーキ安全回路 30に接続されている。ブレーキ安全回路 30は、第 1及び 第 2の卷上機ブレーキ 26〜29の動作状態を監視し、第 1及び第 2の卷上機ブレーキ 26〜29のいずれかが制動動作したら他も制動動作させる。具体的には、ブレーキ安 全回路 30は、通電監視部 26b, 27b, 28b, 29b及び動作監視部 26c, 27c, 28c, 29cのいずれか 1つでも制動動作を検出したら、全ての卷上機ブレーキ 26〜29を制 動動作させる。  [0037] All the energization monitoring units 26b, 27b, 28b, 29b and all the operation monitoring units 26c, 27c, 28c, 29c are connected to the brake safety circuit 30. The brake safety circuit 30 monitors the operating state of the first and second hoisting machine brakes 26 to 29, and if any of the first and second hoisting machine brakes 26 to 29 is braked, the other braking operation is performed. Let Specifically, the brake safety circuit 30 may detect all the hoisting machines when any one of the current monitoring units 26b, 27b, 28b, 29b and the operation monitoring units 26c, 27c, 28c, 29c detects a braking operation. Operate brakes 26-29.
[0038] また、ブレーキ安全回路 30は、制御装置 19のエレベータ安全回路に直列に接続 されており、エレベータシステムの異常等によりエレベータ安全回路が遮断されたとき には、全ての卷上機ブレーキ 26〜29を制動動作させる。 [0039] このようなエレベータ装置では、第 1及び第 2の卷上機ブレーキ 26〜29のいずれ かが制動動作すると、 1つのブレーキ安全回路 30により、他も制動動作されるので、 複数の卷上機 6, 7を用いつつ、非常制動時の停止距離をより安定的に制御すること ができる。 [0038] In addition, the brake safety circuit 30 is connected in series to the elevator safety circuit of the control device 19, and when the elevator safety circuit is shut off due to an abnormality in the elevator system, etc. ~ 29 is braked. [0039] In such an elevator apparatus, when one of the first and second hoisting machine brakes 26 to 29 performs a braking operation, the other braking operation is performed by one brake safety circuit 30. While using upper units 6 and 7, the stopping distance during emergency braking can be controlled more stably.
[0040] なお、実施の形態 5では、卷上機ブレーキ 26〜29の動作のみをブレーキ安全回路 30で監視したが、実施の形態 1のかご搭載ブレーキ装置 21a, 21b、実施の形態 2の 釣合おもり搭載ブレーキ装置 22a, 22b、又は実施の形態 3、 4のロープブレーキ装 置 23等を用いる場合は、これらにっ 、ても監視して制動動作を連動させてもよ!ヽ。  In the fifth embodiment, only the operation of the lifting machine brakes 26 to 29 is monitored by the brake safety circuit 30, but the car-mounted brake devices 21a and 21b of the first embodiment and the fishing of the second embodiment are monitored. When using the brake weight mounted brake device 22a, 22b, or the rope brake device 23 of Embodiments 3 and 4, etc., it is also possible to monitor and link the braking operation!
[0041] また、図 5に示すように、バランスプーリ 13にバランスプーリブレーキ 31, 32を設け てもよい。この場合、バランスプーリブレーキ 31, 32の動作をブレーキ安全回路 30で 監視し、他のブレーキと制動動作を連動させてもよい。また、バランスプーリブレーキ 31 , 32は、バランスプーリ 13の回転を止めるものではなぐ固定側から主ロープ 12を 押さえて制動するものとしてもよぐノ ランスプーリ 13にトラクシヨン能力がなくても主口 ープ 12を制動することができる。さらに、バランスプーリブレーキは、釣合おもり側に ノ ランスプーリを搭載する場合にも付加することができる。  In addition, as shown in FIG. 5, the balance pulley brakes 31 and 32 may be provided on the balance pulley 13. In this case, the operation of the balance pulley brakes 31, 32 may be monitored by the brake safety circuit 30, and the braking operation may be linked with other brakes. Also, the balance pulley brakes 31 and 32 are not intended to stop the rotation of the balance pulley 13, but may be braked by pressing the main rope 12 from the fixed side. 12 can be braked. In addition, a balance pulley brake can be added when a non-reel pulley is mounted on the counterweight side.
[0042] さらに、図 6の例では、ブレーキ安全回路 30は、通電監視部 26b, 27b, 28b, 29b 及び動作監視部 26c, 27c, 28c, 29cのいずれか 1つでも制動動作を検出したら、 全ての卷上機ブレーキ 26〜29を制動動作させる力 このとき、卷上機ブレーキのう ちの少なくとも 1つの制動力をブレーキ安全回路又は動作監視部により制御してもよ い。即ち、制動力を低減させ、力ごの減速度が過大になるのを防止してもよい。これ により、力ごと釣合おもりとの負荷バランスがどのような状態のときでも、かごに過大な 衝撃を与えずに、かごを減速停止させることができる。  [0042] Further, in the example of FIG. 6, the brake safety circuit 30 detects the braking operation in any one of the energization monitoring units 26b, 27b, 28b, 29b and the operation monitoring units 26c, 27c, 28c, 29c, At this time, at least one braking force of the lifting machine brake may be controlled by the brake safety circuit or the operation monitoring unit. That is, the braking force may be reduced to prevent excessive deceleration of the force. As a result, the car can be decelerated and stopped without giving an excessive impact to the car, regardless of the load balance between the force and the counterweight.
[0043] さらにまた、ブレーキ安全回路は、卷上機毎に分けて設けてもよい。例えば図 7で は、第 1の卷上機 6に対応する第 1のブレーキ安全回路 30aと、第 2の卷上機 7に対 応する第 2のブレーキ安全回路 30bとが用いられている。そして、第 1及び第 2のブレ ーキ安全回路 30a, 30b間での信号の送受信が可能となって 、る。  [0043] Furthermore, the brake safety circuit may be provided separately for each hoist. For example, in FIG. 7, a first brake safety circuit 30a corresponding to the first lifting machine 6 and a second brake safety circuit 30b corresponding to the second lifting machine 7 are used. Signals can be transmitted and received between the first and second brake safety circuits 30a and 30b.
このように、卷上機 6, 7毎にブレーキ安全回路 30a, 30bを構成することにより、卷 上機のユニットィ匕を図ることができ、 1台の卷上機を用いるエレベータ装置と 2台の卷 上機を用いるエレベータ装置とで、卷上機を共通化することができる。 In this way, by configuring the brake safety circuits 30a, 30b for each lifting machine 6, 7, the uniting of the lifting machine can be achieved, and an elevator device using one lifting machine and two elevators卷 The elevator machine using the upper machine can be used in common.
また、例えば図 8に示すように、ブレーキコイル 26a, 27a, 28a, 29a、通電監視部 26b, 27b, 28b, 29b及び動作監視咅 26c, 27c, 28c, 29cの全体をシリアノレに接 続してもよい。この場合、何等かの異常により例えば動作監視部 26c, 27c, 28c, 29 cのいずれか 1箇所が遮断されると、図 8の回路が遮断され、全ての卷上機ブレーキ 2 6〜29が強制的に制動動作するので、フェールセーフのシステムを構成することがで き、信頼性を向上させることができる。  In addition, for example, as shown in FIG. 8, the brake coils 26a, 27a, 28a, 29a, the current monitoring units 26b, 27b, 28b, 29b and the operation monitoring rods 26c, 27c, 28c, 29c are all connected to the Silanole. Also good. In this case, for example, if any one of the operation monitoring units 26c, 27c, 28c, and 29c is cut off due to some abnormality, the circuit in FIG. 8 is cut off, and all the lifting machine brakes 26 to 29 are turned on. Since the braking operation is forcibly performed, a fail-safe system can be configured and the reliability can be improved.
さらに、主ロープとして、断面円形のロープを用いても、ベルト状のロープを用いて ちょいことは勿！^である。  Furthermore, even if you use a rope with a circular cross section as the main rope, you should not use a belt-like rope! ^.
