Description
本発明は、エレベータ装置に関する。
The present invention relates to an elevator apparatus.
エレベータ装置には、一般に、かごの昇降速度を常時監視し、かごが所定の過速状態に陥った際にかごを非常停止させる調速機が備えられている。具体的には、調速機は、かごの昇降速度が定格速度を超えて第１過速度（通常は定格速度の１．３倍程度）に達すると、かごを駆動する巻上機の電源及びこの巻上機を制御する制御装置の電源をそれぞれ遮断する。また、調速機は、何らかの原因によりかごの下降速度が第１過速度を超えて第２過速度（通常は定格速度の１．４倍程度）に達すると、かごに設けられた非常止め装置を動作させて、かごを機械的に非常停止させる。
Elevator devices are generally equipped with a governor that constantly monitors the ascending / descending speed of the car and makes the car emergency stop when the car falls into a predetermined overspeed state. Specifically, the speed governor, when the raising / lowering speed of the car exceeds the rated speed and reaches the first overspeed (usually about 1.3 times the rated speed), the power supply of the hoisting machine that drives the car and The power supply of the control device that controls the hoisting machine is shut off. The speed governor is provided with an emergency stop device provided in the car when the car descending speed exceeds the first overspeed and reaches the second overspeed (usually about 1.4 times the rated speed) for some reason. To stop the car mechanically.
そして、このような調速機の背景技術として、特開２００１－１９３１２号公報（特許文献１）がある。この公報には、昇降路の上下方向に配設される調速機ロープの下端が巻掛けられるプーリと、このプーリが回転可能に取付けられる可動リンクと、この可動リンクの自由端に設けられるテンションウェートと、昇降路に立設されるガイドレールの下部にレールクリップを介して取付けられ、可動リンクを回転可能に軸支するブラケットとを有する、と記載されている。
And as a background art of such a governor, there is JP-A-2001-19312 (Patent Document 1). In this publication, a pulley around which a lower end of a governor rope arranged in the vertical direction of a hoistway is wound, a movable link to which the pulley is rotatably mounted, and a tension provided at a free end of the movable link It is described that it has a weight and a bracket attached to a lower part of a guide rail standing on the hoistway via a rail clip and pivotally supporting the movable link.
調速機にあっては、何らかの原因により巻上機に取り付けられたブレーキなどの動作、非常止め装置の動作、緩衝器への衝突によりかごが非常制動される。この際、連結体を介してかごと連結されるかご側調速機ロープは、かごの減速と連動して減速するが、反かご側調速機ロープは慣性で上昇を続け、これによって、調速機ロープ下端で吊持されるテンションウェートは跳ね上がることがある。しかしながら、前述した従来のものでは、このテンションウェートの跳ね上げに十分な対応が施されておらず、大きく跳ね上がると調速機本体、調速機ロープ、テンションウェート及び近傍に設置される機器の損傷を招く恐れがあった。特に、近年、需要が多い高速、高揚程のエレベータ装置にあってこの問題は顕著である。
In the governor, the car is braked emergencyly due to the operation of the brakes attached to the hoisting machine for some reason, the operation of the emergency stop device, and the collision with the shock absorber. At this time, the car governor rope connected to the car through the connecting body decelerates in conjunction with the deceleration of the car, but the anti-car governor rope continues to rise due to inertia. The tension weight suspended at the lower end of the speed rope may jump up. However, in the above-mentioned conventional device, this tension weight is not sufficiently lifted up, and if it jumps up significantly, the governor body, the governor rope, the tension weight and the equipment installed in the vicinity will be damaged. There was a risk of inviting. In particular, this problem is particularly noticeable in high-speed and high-lift elevator devices that are in great demand in recent years.
一方、前述の跳ね上りを防止するために、テンションウェートを上下方向に拘束することは、経年的な調速機ロープ伸びや季節的な湿度の変化による調速機ロープ縮みに対してテンションウェートの位置が調速機ロープに追従せず、テンションウェートの機能喪失や破損が考えられる。
On the other hand, in order to prevent the above-mentioned jumping up, restraining the tension weight in the vertical direction means that the tension weight can be reduced against the governor rope contraction due to the secular governor rope elongation and seasonal humidity change. The position does not follow the governor rope, and the tension weight may be lost or damaged.
本発明は、前述した従来技術における実状からなされたもので、その目的は、ロープの伸び縮みに対して、テンションウェートの機能喪失や破損を抑えながら、かつ、非常制動の際、テンションウェートの跳ね上げを抑止することのできるエレベータ装置を提供することにある。

以下、本発明に係るエレベータ装置の実施例を図に基づき説明する。
Hereinafter, embodiments of an elevator apparatus according to the present invention will be described with reference to the drawings.
本実施形態におけるエレベータ装置１００は、図１に示すように、メインロープ１により吊持された昇降路２を昇降する昇降体であるかご３及びつり合いおもり４と、昇降路２の上部に配置され、メインロープ１を駆動するブレーキを備えた巻上機５と、この巻上機５の近傍に配置されるビームプーリ６と、かご３及びつり合いおもり４の下部に連結されるコンペンロープ７と、このコンペンロープ７の下端に配置されるコンペンプーリ８と、昇降路２の上部に配置される調速機の調速機プーリ９と、昇降路２の下方にあって調速機プーリ９の対向位置に配置される張りプーリ１０と、調速機プーリ９と張りプーリ１０との間に無端状に掛けられる調速機ロープ１１と、張りプーリ１０に負荷を付勢して調速機ロープ１１にテンションを付与するテンションウェート１２と、かご３と調速機ロープ１１とを連結する連結体１３と、かご３が所定の過速度に達したことに応じてかご３を非常制動する非常止め装置２２と、昇降路底部にかごが衝突した場合でも、かご内の人が安全であるように衝撃を小さくして停止させる緩衝器１５とを備えている。本実施形態では張りプーリ１０とテンションウェート１２はテンション付与部材２１に設けられている。調速機ロープ１１は連結体１３によってかご３と連結されているので、本実施形態では昇降体であるかご３の昇降に応じて駆動される。また、かご３はかごガイドレール２５にガイドされて昇降路２内を昇降し、非常止め装置２２は作動した際にかごガイドレール２５を掴んでかご３を非常制動させる。
As shown in FIG. 1, the elevator apparatus 100 according to the present embodiment is disposed at the upper part of the hoistway 2 and a car 3 and a counterweight 4 that are elevating bodies that elevate and lower the hoistway 2 suspended by the main rope 1. A hoisting machine 5 provided with a brake for driving the main rope 1, a beam pulley 6 disposed in the vicinity of the hoisting machine 5, a compen- sion rope 7 connected to the lower part of the car 3 and the counterweight 4, Compensation pulley 8 disposed at the lower end of compensation rope 7, governor pulley 9 of the governor disposed at the upper part of hoistway 2, and opposite position of governor pulley 9 below hoistway 2 A tension pulley 10 disposed on the governor pulley 9, a governor rope 11 that is endlessly hung between the tension pulley 9 and the tension pulley 10, and a load on the tension pulley 10 to bias the governor rope 11 With tension The tension weight 12 to be connected, the connecting body 13 for connecting the car 3 and the governor rope 11, the emergency stop device 22 for emergency braking of the car 3 when the car 3 reaches a predetermined overspeed, Even when the car collides with the road bottom, a shock absorber 15 is provided that stops the car with a small impact so that the person inside the car is safe. In the present embodiment, the tension pulley 10 and the tension weight 12 are provided on the tension applying member 21. Since the governor rope 11 is connected to the car 3 by the connecting body 13, in this embodiment, the speed governor rope 11 is driven in accordance with the raising and lowering of the car 3 that is the lifting body. The car 3 is guided by the car guide rail 25 and moves up and down in the hoistway 2, and the emergency stop device 22 grips the car guide rail 25 and operates the emergency braking of the car 3 when operated.
そして、第１の実施例では、ロープの伸び縮みに対して、調速機ロープ１１にテンションを付与するというテンション付与部材２１の機能を失わせること無く、かつ、ブレーキなどの動作、非常止め装置の動作、緩衝器への衝突によるかご３の非常制動の際、テンション付与部材２１が跳ね上がることを抑止する工夫がなされている。具体的には、図２に示すように、昇降路２の下部にテンション付与部材２１の左右両側に一対立設され、テンション付与部材２１の移動を案内するガイドレール１４と、テンション付与部材２１とガイドレール１４との間に設けられ、ガイドレール１４に摺接し、テンション付与部材２１の跳ね上がりを抑止する摩擦ユニット１６と、テンション付与部材２１の上部に設けられるロッド１７と、摩擦ユニット１６間に渡されるブラケット１８と、ロッド１７が挿通され、テンション付与部材２１とブラケット１８との間に配置される緩衝ばね１９と、ブラケット１８より高い位置にあってロッド１７に装着される受け部材２０とを備えている。 このように摩擦ユニット１６は一対のガイドレール１４にそれぞれ取り付けられている。そして、テンション付与部材２１は一対のガイドレール１４に取り付けられた摩擦ユニット１６をブラケット１８で連結し、ブラケット１８に挿通されたロッド１７を介して摩擦ユニット１６と連結されている。なお、緩衝ばね１９とブラケット１８との間、また、ブラケット１８と受け部材２０との間にはそれぞれ、通常時において所定の空隙が設けられている。
In the first embodiment, the function of the tension applying member 21 for applying tension to the governor rope 11 with respect to the expansion and contraction of the rope is not lost, and the operation of the brake and the emergency stop device are performed. In the emergency braking of the car 3 due to the above operation and the collision with the shock absorber, a device is devised to prevent the tension applying member 21 from jumping up. Specifically, as shown in FIG. 2, a guide rail 14 that is provided opposite to the right and left sides of the tension applying member 21 at the lower part of the hoistway 2 and guides the movement of the tension applying member 21, and the tension applying member 21. Passed between the friction unit 16 and the friction unit 16 provided between the guide rail 14 and slidingly contacting the guide rail 14 to prevent the tension application member 21 from jumping up, the rod 17 provided on the upper part of the tension application member 21, and the friction unit 16. Bracket 18, rod 17 is inserted, buffer spring 19 is disposed between tension applying member 21 and bracket 18, and receiving member 20 is mounted on rod 17 at a position higher than bracket 18. ing. Thus, the friction unit 16 is attached to each of the pair of guide rails 14. The tension applying member 21 connects the friction unit 16 attached to the pair of guide rails 14 by a bracket 18 and is connected to the friction unit 16 through a rod 17 inserted through the bracket 18. Note that a predetermined gap is provided between the buffer spring 19 and the bracket 18 and between the bracket 18 and the receiving member 20, respectively.
摩擦ユニット１６は、図３に示すように、ブラケット１８に回転可能に支持される一対のアーム１６ａと、一対のアーム１６ａの上部に挿通されるロッド１６ｂと、一対のアーム１６ａをガイドレール１４方向に付勢してガイドレール１４を挟持するためのばね１６ｃと、アーム１６ａにより支持され、ガイドレール１４に摺動可能に摺接するシュー１６ｄとを有して成っている。
As shown in FIG. 3, the friction unit 16 includes a pair of arms 16a rotatably supported by the bracket 18, a rod 16b inserted through the upper portions of the pair of arms 16a, and the pair of arms 16a in the direction of the guide rail 14. And a shoe 16d supported by the arm 16a and slidably slidably contacting the guide rail 14.
第１の実施例にあっては、経年的な調速機ロープ１１伸びに伴い、テンション付与部材２１は徐々に下方に移動した場合、ブラケット１８と受け板材２０の間の隙間がなくなり、さらにテンション付与部材２１が下方に移動すると、受け板材２０により、ブラケット１８を介して摩擦ユニット１６はシュー１６ｄによってガイドレール１４に摺動しながらテンション付与部材２１と共に下方に移動する。
In the first embodiment, when the tension applying member 21 gradually moves downward as the governor rope 11 elapses over time, there is no gap between the bracket 18 and the backing plate material 20, and the tension is further increased. When the applying member 21 moves downward, the friction unit 16 is moved downward together with the tension applying member 21 by the receiving plate member 20 through the bracket 18 while sliding on the guide rail 14 by the shoe 16d.
一方、湿気の多い季節などではロープが縮むことがあり、これに伴いテンション付与部材２１は徐々に上方に移動した場合、ブラケット１８とテンション付与部材２１に取り付いたロッド１７に備えた緩衝ばね１９との隙間がなくなり、さらにテンション付与部材２１が上方に移動すると、緩衝ばね１９により、ブラケット１８を介して摩擦ユニット１６は上方に移動する。前記により調速機ロープ１１の伸び縮みによる摩擦ユニット１６の位置を調整している。
On the other hand, the rope may shrink in a humid season or the like, and when the tension applying member 21 gradually moves upward, the buffer spring 19 provided on the bracket 17 and the rod 17 attached to the tension applying member 21 When the tension applying member 21 further moves upward, the friction unit 16 moves upward via the bracket 18 by the buffer spring 19. As described above, the position of the friction unit 16 due to the expansion and contraction of the governor rope 11 is adjusted.
このように、テンション付与部材２１と摩擦ユニット１６は、テンション付与部材２１が所定距離の範囲で上下方向に移動する際には摩擦ユニット１６に対してその移動力を伝達せず、テンション付与部材２１が所定距離以上上下方向に移動する際には摩擦ユニット１６にその移動力が伝達されて摩擦ユニット１６が摩擦力を発生しながら追従して移動する。したがって、ロープの伸び縮みに対して、テンションウェートの機能喪失を十分に確保した状態を確保できる。
Thus, the tension applying member 21 and the friction unit 16 do not transmit the moving force to the friction unit 16 when the tension applying member 21 moves in the vertical direction within a range of a predetermined distance. Is moved in the vertical direction more than a predetermined distance, the moving force is transmitted to the friction unit 16, and the friction unit 16 follows and moves while generating the friction force. Therefore, it is possible to secure a state in which the loss of function of the tension weight is sufficiently secured against the expansion and contraction of the rope.
一方、かご３の非常制動時のテンション付与部材２１の跳ね上り防止については、何らかの原因により、かご３の非常制動の際、連結体１３を介してかご３と連結されるかご側調速機ロープは、かご３の減速と連動して減速するが、反かご側調速機ロープは慣性で上昇を続け、これによって、調速機ロープ１１下端で吊持されるテンション付与部材２１は跳ね上がる。跳ね上がったテンション付与部材２１は、このテンション付与部材２１とブラケット１８との間に介在された緩衝ばね１９により緩衝されると共に、緩衝ばね１９が衝突することにより上方向に大きな力を受けたブラケット１８は、摩擦ユニット１６のシュー１６ｄがガイドレール１４に摺接することで、摩擦抵抗により減速、次いで停止し、所定位置以上、上昇することが抑止される。
On the other hand, with respect to prevention of jumping of the tension applying member 21 during emergency braking of the car 3, for some reason, the car side governor rope connected to the car 3 via the connecting body 13 during emergency braking of the car 3. However, the anti-car side governor rope continues to rise due to inertia, and the tension applying member 21 suspended at the lower end of the governor rope 11 jumps up. The tension applying member 21 that has jumped up is buffered by a buffer spring 19 interposed between the tension applying member 21 and the bracket 18, and the bracket 18 that has received a large upward force due to the collision of the buffer spring 19. When the shoe 16d of the friction unit 16 is slidably contacted with the guide rail 14, it is decelerated by the frictional resistance, then stopped, and it is prevented from rising above a predetermined position.
したがって、本実施形態によれば、第１の実施例によれば、ロープの伸び縮みに対して、テンションウェート及び摩擦ユニットの機能を失わせること無く、かつ、非常制動の際、テンション付与部材２１の跳ね上げを抑止することによって、調速機本体、調速機ロープ、テンション付与部材及び近傍に設置される機器が損傷することを防ぐことができる。
Therefore, according to the present embodiment, according to the first example, the tension applying member 21 is not lost in the function of the tension weight and the friction unit with respect to the expansion and contraction of the rope, and at the time of emergency braking. By inhibiting the jumping up of the governor, it is possible to prevent damage to the governor body, the governor rope, the tension applying member, and the devices installed in the vicinity.
また、ロッド１７には、ブラケット１８とテンション付与部材２１の間の部位に緩衝ばね１９を設けているので、跳ね上がったテンション付与部材２１の衝撃を緩衝させながらブラケット１８にその力を伝達し、緩衝により相殺できなかった力も摩擦ユニット１６とガイドレール１４との摺動により緩やかに相殺されるので、より良好にテンション付与部材２１の跳ね上げを抑止することが可能となる。
Further, since the rod 17 is provided with a buffer spring 19 at a portion between the bracket 18 and the tension applying member 21, the force is transmitted to the bracket 18 while buffering the impact of the jumping tension applying member 21, and the buffer 17 is buffered. Since the force that could not be canceled by the frictional unit 16 and the guide rail 14 is gradually canceled by the sliding, it is possible to suppress the jumping of the tension applying member 21 better.
ここで、本発明に係るエレベータ装置の第２の実施例を図４に基づき説明する。なお、前述したものと同等のものには同一符号が付してある。
Here, a second embodiment of the elevator apparatus according to the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the thing equivalent to what was mentioned above.
第２の実施例のエレベータ装置は、図４に示すように、摩擦ユニット１６がテンション付与部材２１の下方に配置された点において前述した第１の実施例と異なるものである。すなわち、昇降路２の下部に対となって立設され、テンション付与部材２１の移動を案内するガイドレール２４と、テンション付与部材２１とガイドレール２４との間に設けられ、ガイドレール２４に摺接し、テンション付与部材２１の跳ね上がりを抑止する摩擦ユニット２６と、テンション付与部材２１の下部に設けられるロッド２７と、摩擦ユニット２６間に渡されるブラケット２８と、ロッド２７が挿通され、テンション付与部材２１とブラケット２８との間に配置される緩衝ばね２９と、ブラケット２８より低い位置にあってロッド２７に装着される受け部材３０とを備えている。
The elevator apparatus according to the second embodiment is different from the first embodiment described above in that the friction unit 16 is disposed below the tension applying member 21 as shown in FIG. That is, the guide rail 24 is installed in a pair in the lower part of the hoistway 2 and guides the movement of the tension applying member 21. The guide rail 24 is provided between the tension applying member 21 and the guide rail 24. A friction unit 26 that contacts and prevents the tension applying member 21 from jumping up, a rod 27 provided below the tension applying member 21, a bracket 28 passed between the friction units 26, and the rod 27 are inserted into the tension applying member 21. And a bracket spring 28 disposed between the bracket 28 and a receiving member 30 mounted on the rod 27 at a position lower than the bracket 28.
第２の実施例によれば、前述した第１の実施例と同様、ロープの伸び縮みに対して、テンションウェートの機能を失わせること無く、かつ、非常制動の際、テンション付与部材２１の跳ね上げを抑止することによって、調速機本体、調速機ロープ、テンション付与部材及び近傍に設置される機器が損傷することを防ぐことができる。
According to the second embodiment, similar to the first embodiment described above, the tension applying member 21 jumps without losing the function of the tension weight with respect to the expansion and contraction of the rope and during emergency braking. By suppressing the raising, it is possible to prevent damage to the governor body, the governor rope, the tension applying member, and the devices installed in the vicinity.
なお、上記実施例１および２では昇降体としてかご３と調速機ロープ１１を連結体１３にて連結した例を挙げて説明したが、昇降体としてつり合いおもり４にこのような構成を適用したものであってもよい。
また、本実施形態ではテンション付与部材２１と摩擦ユニット１６を連結する構成として、ブラケット１８とロッド１７を用いたが、これのみに限られるものではない。たとえば、ガイドレールを一対設けずに丸棒をガイドレールとして一本だけ立設し、この丸棒の摺面に摺動可能に摺接する円筒型の摩擦ユニットを設けて、これをテンション付与部材と連結する構成であってもよい。 In the first and second embodiments, the example in which the car 3 and thegovernor rope 11 are connected by the connecting body 13 as the lifting body has been described. However, such a configuration is applied to the counterweight 4 as the lifting body. It may be a thing.
Further, in the present embodiment, thebracket 18 and the rod 17 are used as a configuration for connecting the tension applying member 21 and the friction unit 16, but the configuration is not limited thereto. For example, without providing a pair of guide rails, only one round bar is set up as a guide rail, and a cylindrical friction unit is slidably brought into sliding contact with the sliding surface of the round bar. The structure which connects may be sufficient.
また、本実施形態ではテンション付与部材２１と摩擦ユニット１６を連結する構成として、ブラケット１８とロッド１７を用いたが、これのみに限られるものではない。たとえば、ガイドレールを一対設けずに丸棒をガイドレールとして一本だけ立設し、この丸棒の摺面に摺動可能に摺接する円筒型の摩擦ユニットを設けて、これをテンション付与部材と連結する構成であってもよい。 In the first and second embodiments, the example in which the car 3 and the
