Description

本発明は、エレベーター用調速機に関する。   The present invention relates to a governor for an elevator.

従来から、エレベーター用調速機として様々なものが提案されている。例えば、下記特許文献１には、落下したくさび部をコイルばねの弾性力によって押し付け、把持片との間でガバナロープを把持するようにしたディスク形の調速機が記載されている。   Conventionally, various elevator governors have been proposed. For example, Patent Document 1 described below describes a disk-type speed governor in which a wedge part that has been dropped is pressed by the elastic force of a coil spring and a governor rope is gripped between gripping pieces.

特開昭５５−２６１４０号（第５図等）JP 55-26140 (Fig. 5 etc.)

しかしながら、上記特許文献１に記載された調速機では、コイルばねを用いているため、ガバナロープを把持する機構が大型化し、これに伴いエレベーター用調速機も大きくなってしまう傾向にあった。   However, since the speed governor described in Patent Document 1 uses a coil spring, the mechanism for gripping the governor rope is increased in size, and the speed governor for the elevator tends to be increased accordingly.

本発明の目的は、小型化が容易なエレベーター用調速機を提供することにある。   An object of the present invention is to provide an elevator governor that can be easily downsized.

上記目的を達成するために、本発明では、乗りかごと連動して移動するガバナロープが巻掛けてある軸支持されたガバナプーリと、該プーリの回転に伴う遠心力により爪部が前記プーリの外径側へ移動する振子と、移動した前記爪部との当接により回動してスイッチを解除させる係合片と、自重により回動し対向する把持片との間で前記ガバナロープを把持するくさび部と、前記プーリの外径側へ更に移動した前記爪部との当接により回動して前記くさび部の支持を解除するフックと、レバーとを備えたエレベーター用調速機において、皿ばねの弾性力によって、前記くさび部を前記ガバナロープへ押し付けるように構成し、前記くさび部が２つ設けられ、前記乗りかごが下降方向の過速状態になった場合に、一方のくさび部が前記ガバナロープを把持し、前記乗りかごが上昇方向の過速状態になった場合に、他方のくさび部が前記ガバナロープを把持し、前記フックは、前記爪部との当接により回動する第１フックと、前記第１フックの時計回りの回動により前記一方のくさび部の支持を解除する第２フックと、前記第１フックの反時計回りの回動により前記他方のくさび部の支持を解除する第３フックとを有し、前記係合片は前記爪部と当接して回動可能であり、過速状態となった場合に前記第１フックが前記爪部と接触して倒れ、前記レバーは、前記くさび部が落下した場合に倒され、前記第１フックのつっかえ棒となるように設けられた。


In order to achieve the above object, according to the present invention, a shaft-supported governor pulley around which a governor rope moving in conjunction with a car is wound, and a claw portion is formed on the outer diameter of the pulley by centrifugal force accompanying the rotation of the pulley. A wedge portion that grips the governor rope between a pendulum that moves to the side, an engagement piece that rotates by contact with the moved claw portion to release the switch, and a gripping piece that rotates by its own weight and faces each other An elevator governor comprising: a lever that rotates by releasing contact with the claw portion that has further moved to the outer diameter side of the pulley and releases the support of the wedge portion; by the elastic force, the wedge portion configured to press to the governor rope, the wedge part 2 is provided, when the car has become overrunning state of the decreasing direction, one of the wedge portion is the Gabanaro A first hook that grips the governor rope, and the hook is rotated by contact with the claw when the car is in an overspeed state in the ascending direction. A second hook that releases the support of the one wedge portion by the clockwise rotation of the first hook, and a support of the other wedge portion by the counterclockwise rotation of the first hook. A third hook, and the engagement piece is rotatable by contacting the claw portion, and when the overspeed state is reached, the first hook is brought into contact with the claw portion and falls down, and the lever Is provided so as to be turned over when the wedge part falls and to become a stick for the first hook.


本発明によれば、小型化が容易なエレベーター用調速機を提供できる。特に、乗りかごの上昇方向及び下降方向の両方向の過速状態について、ガバナロープの把持を必要とする場合は、その効果が顕著である。   ADVANTAGE OF THE INVENTION According to this invention, the governor for elevators with easy size reduction can be provided. In particular, the effect is remarkable when it is necessary to grip the governor rope in the overspeed state in both the upward and downward directions of the car.

以下、本発明による第一の実施の形態を図１〜図６に基づいて説明する。   Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

The speed governor 6 includes a pendulum receiver 14 fixed on the shaft of the governor pulley 13, rotation fulcrums 15, 15 A, pins 16, 16 A, two pendulums 18, 18 A coupled by a connecting lever 17, and a pendulum opening. A spring 19 for determining the amount, a nut 20 for guiding the spring 19 and adjusting the spring force, and an adjuster 20A comprising a screw, and a pin 21 for the adjuster 20A are provided. Further, the speed governor 6 has a switch 22 fixed to the frame 11, a switch piece 23 having a switch piece 23 that can rotate with respect to the governor pulley shaft 12, a pin 29 on which the switch cam 24 rides, and a frame 11A (see FIG. 3). ) And three hooks (a first hook 26, a second hook 27, and a third hook 28) that are coaxially disposed on the shaft 25.

また、第２フック２７，第３フック２８には、第１フック２６を両端から挟むようにねじ３０，３０Ａが設けられている。そして、調速機６は、くさび部３１，３１Ａ，くさび部３１，３１Ａの回転支点となる軸３２，３２Ａ，第２フック２７，第３フック２８がかかるピン３３，３３Ａを備えている。くさび部３１，３１Ａには、ピン３４，３４Ａが設けてある。レバー３５，３５Ａはフレーム１１Ａ（図３参照）に固定されたピン３６，
３６Ａを中心に回動自在に取り付けられ、エレベーター平常運運転時は自重により図示の方向にモーメントが作用するようになっている。 The second hook 27 and the third hook 28 are provided with screws 30 and 30A so as to sandwich the first hook 26 from both ends. The speed governor 6 includes pins 33 and 33A on which the wedge portions 31 and 31A, the shafts 32 and 32A serving as the rotation fulcrums of the wedge portions 31 and 31A, the second hook 27, and the third hook 28 are applied. The wedge portions 31, 31A are provided with pins 34, 34A. The levers 35 and 35A are pins 36 fixed to the frame 11A (see FIG. 3).
It is attached so as to be rotatable around 36A, and a moment acts in the direction shown in the figure by its own weight during elevator normal operation.

くさび部３１とくさび部３１Ａの間には、ばね受け４０，４１，４２が設けられ、ばね受け４１，４２の間には皿ばね４３が複数個配置されている。尚、図２では８枚の皿ばねが交互に配置されている。ばね受け４１，４２には、ねじがあり、ばね受け４１を回すことにより、皿ばね４３の圧縮量を変えることができるので皿ばね４３のばね力の調整が可能である。   Between the wedge part 31 and the wedge part 31A, spring receivers 40, 41, 42 are provided, and a plurality of disc springs 43 are arranged between the spring receivers 41, 42. In FIG. 2, eight disc springs are alternately arranged. The spring receivers 41 and 42 have screws, and the amount of compression of the disc spring 43 can be changed by turning the spring receiver 41, so that the spring force of the disc spring 43 can be adjusted.

第１フック２６，第２フック２７，第３フック２８とくさび部３１，３１Ａの周りは、図３に示すように構成されている。レバー３５，３５Ａとピン３６，３６Ａは止め輪４４，４４Ａにより、外れることはない。ストッパ４５，４５Ａは、レバー３５，３５Ａの回転範囲を制限するものである。   The first hook 26, the second hook 27, the third hook 28, and the wedge portions 31, 31A are configured as shown in FIG. The levers 35 and 35A and the pins 36 and 36A are not detached by the retaining rings 44 and 44A. The stoppers 45 and 45A limit the rotation range of the levers 35 and 35A.

次に、調速機６の動作について説明する。図４に乗りかご１が上昇方向に過速し、ガバナプーリ１３が反時計回りの方向に過速してスイッチオフ動作に達した場合を示し、図５ではさらに過速が進み、ガバナロープ７を把持する動作に達した場合を示す。   Next, the operation of the governor 6 will be described. FIG. 4 shows the case where the car 1 is overspeeded in the upward direction and the governor pulley 13 is overspeeded in the counterclockwise direction and reaches the switch-off operation. In FIG. 5, the overspeed further proceeds and the governor rope 7 is gripped. The case where the operation to be performed is reached is shown.

まず、図４では、ガバナプーリ１３の回転に伴う遠心力により、振子１８，１８Ａが開き、振子１８，１８Ａの先端の爪部４６，４６Ａがガバナプーリ１３の外径側へ移動する。そして、ある速度まで達すると、爪部４６，４６Ａがスイッチピース２３と当接し、このスイッチピース２３とスイッチカムからなる係合片を反時計回りに回動して蹴り倒すことにより、スイッチ２２が解除状態になる。このときまだ、第１フック２６は爪部４６，４６Ａに接触していなので、第１フック２６は倒立したままである。   First, in FIG. 4, the pendulum 18, 18 </ b> A is opened by the centrifugal force accompanying the rotation of the governor pulley 13, and the claw portions 46, 46 </ b> A at the tip of the pendulum 18, 18 </ b> A move to the outer diameter side of the governor pulley 13. When the speed reaches a certain speed, the claw portions 46, 46A come into contact with the switch piece 23, and the switch 22 and the switch cam are rotated counterclockwise to kick the switch 22 so that the switch 22 It becomes a release state. At this time, since the first hook 26 is still in contact with the claw portions 46 and 46A, the first hook 26 remains inverted.

さらに過速が進み、一層振子１８，１８Ａが開き、爪部４６，４６Ａがガバナプーリ
１３の外径側へ更に移動すると、図５のように爪部４６，４６Ａが第１フック２６と当接し、この第１フック２６を蹴り倒して軸２５を中心に時計周りに回動させる。第１フック２６は、ねじ３０Ａを介して、第２フック２７を軸２５を中心に反時計回りに回転させるので、第２フック２７とピン３３との係合が外れ、くさび部３１の支持が解除される。くさび部３１は自重により、軸３２を中心に、反時計回りに落下しながら回動し、対向する把持片３７との間にガバナロープ７を挟みこむ。このとき、軸３２は図５のように右方向へ移動するので、皿ばね４３の弾性力によってくさび部３１をガバナロープ７へ押し付け、くさび部３１と把持片３７との間でガバナロープ７が把持される。このときの把持力は、皿ばね４３の弾性力とガバナロープ７接触部（くさび部３１と把持片３７）との摩擦特性により決定される。また、くさび部３１が落下するとき、ピン３４がピン３６を中心にレバー３５を反時計回りに回動させる。すると結果的に、レバー３５は図５の状態となり、第１フック２６の下部を支えるような位置となる。 When the overspeed further progresses, the pendulum 18, 18A further opens, and the claw portions 46, 46A further move toward the outer diameter side of the governor pulley 13, the claw portions 46, 46A come into contact with the first hook 26 as shown in FIG. The first hook 26 is kicked down and rotated clockwise about the shaft 25. Since the first hook 26 rotates the second hook 27 counterclockwise about the shaft 25 via the screw 30A, the engagement between the second hook 27 and the pin 33 is released, and the wedge portion 31 is supported. Canceled. The wedge portion 31 is rotated by being dropped counterclockwise about the shaft 32 by its own weight, and the governor rope 7 is sandwiched between the gripping pieces 37 facing each other. At this time, since the shaft 32 moves rightward as shown in FIG. 5, the wedge portion 31 is pressed against the governor rope 7 by the elastic force of the disc spring 43, and the governor rope 7 is gripped between the wedge portion 31 and the gripping piece 37. The The gripping force at this time is determined by the frictional characteristics between the elastic force of the disc spring 43 and the governor rope 7 contact portion (the wedge portion 31 and the gripping piece 37). Further, when the wedge portion 31 falls, the pin 34 rotates the lever 35 counterclockwise around the pin 36. As a result, the lever 35 is in the state shown in FIG. 5 and is in a position to support the lower portion of the first hook 26.

このように、皿ばね４３を用いることにより、コイルばねを用いる場合と比べて、ガバナロープ７を把持する機構を小形にできる。更に、くさび部３１，３１Ａの間に皿ばね
４３を配置し、皿ばね４３の一端側が一方のくさび部３１に支持され、皿ばね４３の他端側が他方のくさび部３１Ａに支持されているので、共通の皿ばね４３からそれぞれの把持力を得ることができ、簡単なガバナロープ保持構造で小型な調速機６が実現可能となる。従って、乗りかご１の下降方向の過速状態だけでなく上昇方向の過速状態においてもガバナロープ７を把持するために、くさび部を２個設けたディスク形調速機であっても、全体を小形化できる。 Thus, by using the disc spring 43, the mechanism for gripping the governor rope 7 can be made smaller than in the case of using a coil spring. Further, a disc spring 43 is arranged between the wedge portions 31, 31A, and one end side of the disc spring 43 is supported by one wedge portion 31, and the other end side of the disc spring 43 is supported by the other wedge portion 31A. Each gripping force can be obtained from the common disc spring 43, and a small speed governor 6 can be realized with a simple governor rope holding structure. Therefore, in order to hold the governor rope 7 not only in the overspeed state in the descending direction of the car 1 but also in the overspeed state in the ascending direction, even if the disc type governor provided with two wedge portions is used as a whole. Can be downsized.

本発明では、くさび部３１が落下した場合、図５のように、ピン３４がレバー３５を反時計周りの方向へ倒すので、第１フック２６を時計回りの方向へ倒すとともに第１フック２６のつっかえ棒の役目を果たす。これにより、スイッチカム２４は、ピン２９からずり落ちるので、確実にスイッチ２２が切れるとともに、手動で第１フック２６，第２フック２７，くさび部３１を元の状態に戻さない限り、スイッチ２２を復帰させることはできない。このように、くさび部３１が落下した場合、確実にスイッチ２２が切れた状態を保持することが可能であるため、安全なエレベーターシステムが構築できる。   In the present invention, when the wedge part 31 falls, the pin 34 tilts the lever 35 in the counterclockwise direction as shown in FIG. 5, so that the first hook 26 is tilted in the clockwise direction and the first hook 26 Play the role of a stick. As a result, the switch cam 24 slips off from the pin 29, so that the switch 22 is surely cut off, and the switch 22 is reset unless the first hook 26, the second hook 27, and the wedge portion 31 are manually returned to the original state. I can't let you. In this way, when the wedge part 31 falls, it is possible to reliably maintain the state in which the switch 22 is turned off, so that a safe elevator system can be constructed.

尚、乗りかご１が上昇方向へ過速し、ガバナプーリ１３が時計周りの方向に過速した場合も、ガバナプーリ１３が所定の回転速度に達すると、スイッチオフ動作が成される。さらに乗りかご１の過速が進むと、くさび部３１Ａと把持片３７Ａとの間でガバナロープ７を把持する動作が成される。このように、乗りかご１が下降方向の過速状態になった場合は、一方のくさび部３１がガバナロープ７を把持し、乗りかご１が上昇方向の過速状態になった場合は、他方のくさび部３１Ａがガバナロープ７を把持するように構成されている。   Even when the car 1 overspeeds in the upward direction and the governor pulley 13 overspeeds clockwise, the switch-off operation is performed when the governor pulley 13 reaches a predetermined rotational speed. When the speed of the car 1 further increases, an operation of gripping the governor rope 7 is performed between the wedge portion 31A and the gripping piece 37A. Thus, when the car 1 is in the overspeed state in the descending direction, one wedge portion 31 grips the governor rope 7, and when the car 1 is in the overspeed state in the ascending direction, The wedge portion 31 </ b> A is configured to grip the governor rope 7.
