Abstract

In an elevator device, a car is suspended on one side of a drive sheave by suspension means and a counterbalance weight is suspended by the suspension means on the other side. On the car is mounted an emergency stop device for emergency-stopping the car by engaging with a car guide rail. In an operation check test of the emergency stop device, a holding-force application device applies a holding force to that part of the suspension means which is on the counterbalance weight side of the drive sheave, where the applied holding force is less than an imbalance load between the car and the counterbalance weight.

Description

エレベータ装置及びその試験方法Elevator apparatus and test method thereof
　この発明は、かごに非常止め装置が搭載されているエレベータ装置、及びその非常止め装置の作動確認を行う試験方法に関するものである。 The present invention relates to an elevator apparatus in which an emergency stop device is mounted on a car, and a test method for confirming the operation of the emergency stop device.
　一般に、トラクション方式のエレベータ装置では、非常止め装置の作動試験を実施する際、非常止め装置を作動させた状態で、かごが下降する方向へ巻上機を運転する。そして、駆動シーブが空転してかごが下降しなければ、非常止め装置が正常に作動していると判断される（例えば、特許文献１参照）。 Generally, in an elevator device of a traction type, when performing an operation test of the emergency stop device, the hoisting machine is operated in a direction in which the car descends with the emergency stop device activated. If the drive sheave is idle and the car does not descend, it is determined that the emergency stop device is operating normally (see, for example, Patent Document 1).
　上記のような非常止め装置の試験方法では、トラクション限界を超えてロープが完全にスリップするまで駆動シーブを回転させる必要があるため、次式の条件が必要となる。
　Ｗ２／Ｗ１≧Γｓ　・・・（１）
　但し、Ｗ１はかごの重量、Ｗ２は釣合おもりの重量、Γｓはトラクション限界のときのトラクション能力である。 In the test method of the emergency stop device as described above, the drive sheave needs to be rotated until the rope completely slips beyond the traction limit.
W2 / W1 ≧ Γs (1)
However, W1 is the weight of the car, W2 is the weight of the counterweight, and Γs is the traction capacity at the traction limit.
　また、駆動シーブの直径をＤとすると、ロープスリップを発生させるために必要な駆動シーブでのトルクＴｓ１は次式で表される。
　Ｔｓ１＝Ｄ／２×（Ｗ２－Ｗ１）　・・・（２）
　そして、式（１）を式（２）に代入することにより、次式が得られる。
　Ｔｓ１＝Ｄ／２×Ｗ２×（１－１／Γｓ）　・・・（３）
　従って、釣合おもりの重量が大きいと駆動シーブを空転させるために必要なトルクが大きくなることが分かる。 Further, assuming that the diameter of the drive sheave is D, the torque Ts1 at the drive sheave necessary for generating the rope slip is expressed by the following equation.
Ts1 = D / 2 × (W2-W1) (2)
Then, by substituting equation (1) into equation (2), the following equation is obtained.
Ts1 = D / 2 × W2 × (1-1 / Γs) (3)
Therefore, it can be seen that when the weight of the counterweight is large, the torque required to idle the drive sheave increases.
　例えば、エレベータ装置の定格荷重をＣＡＰとすると、アンバランストルクＴ０は次式により計算される。但し、Ｗ２＝Ｗ１＋０．５ＣＡＰとする。
　Ｔ０＝Ｄ／２×｛（Ｗ１＋ＣＡＰ）－Ｗ２｝＝０．２５ＣＡＰ×Ｄ　・・・（４） For example, when the rated load of the elevator apparatus is CAP, the unbalance torque T0 is calculated by the following equation. However, W2 = W1 + 0.5CAP.
T0 = D / 2 × {(W1 + CAP) −W2} = 0.25CAP × D (4)
　これに対して、例えば駆動シーブのロープ溝形状（４０°のＶ字溝と仮定）による形状係数をＫ２＝１／ｓｉｎ（４０／２）＝２．９２、駆動シーブとロープとの間の摩擦係数をμ＝０．２、駆動シーブとロープとの接触角度をθ＝１５０°とすると、次式が成立する。
　Ｔｓ１＝Ｄ／２×Ｗ２×｛１－１／（ｅ2.92×0.2×150/180×π）｝
＝０．７８３×Ｗ２×Ｄ／２　・・・（５） In contrast, for example, the shape factor of the drive sheave rope groove shape (assuming a 40 ° V-shaped groove) is K2 = 1 / sin (40/2) = 2.92, and the friction between the drive sheave and the rope. When the coefficient is μ = 0.2 and the contact angle between the drive sheave and the rope is θ = 150 °, the following equation is established.
Ts1 = D / 2 × W2 × {1-1 / (e 2.92 × 0.2 × 150/180 × π )}
= 0.783 x W2 x D / 2 (5)
　ここで、かごの重量Ｗ１を１．５×ＣＡＰとすると、Ｗ２＝２．０ＣＡＰ（ロープ類の重量は無視）であるから、次式が成立する。
　Ｔｓ１＝０．７８３ＣＡＰ×Ｄ　・・・（６） Here, if the weight W1 of the car is 1.5 × CAP, W2 = 2.0CAP (ignoring the weight of the ropes), so the following equation is established.
Ts1 = 0.833CAP × D (6)
　式（４）と式（６）とを比較すると、駆動シーブの空転に必要なトルクＴｓ１は、アンバランストルクＴ０の３倍程度となり、かごの加減速に必要なトルク（一般的にはアンバランストルクＴ０の２倍程度）を考慮しても、非常止め装置の作動確認試験のためのみに大きなモータトルクが必要とされる。 Comparing equation (4) and equation (6), the torque Ts1 required for the idling of the drive sheave is about three times the unbalance torque T0, and the torque required for the acceleration / deceleration of the car (generally, unbalance) In consideration of the torque T0), a large motor torque is required only for the operation check test of the emergency stop device.
　また、トラクション式のエレベータ装置には、かご又は釣合おもりが昇降路底部のバッファに到達した状態で、そのまま駆動シーブを回転させても、釣合おもり又はかごをそれ以上持ち上げないという性能が要求される。このような性能を満足することを確認するための試験方法として、最も厳しい条件、即ちかごを無負荷状態とするとともに釣合おもりをバッファ上に載せ、かごを上昇させる方向へ駆動シーブを回転させた状態で、ロープに対して駆動シーブが空転することを確認する方法がある。 In addition, the traction type elevator device requires the performance that the counterweight or car cannot be lifted any more even if the drive sheave is rotated as it is when the car or counterweight reaches the buffer at the bottom of the hoistway. Is done. As a test method for confirming that these performances are satisfied, the most severe condition, that is, the car is put in a no-load state, a counterweight is placed on the buffer, and the drive sheave is rotated in the direction of raising the car. There is a method of confirming that the drive sheave is idling with respect to the rope in the state where it is in the state.
　この試験で駆動シーブを空転させるのに必要なトルクＴｓ２は、次式により求められる。
　Ｔｓ２＝Ｄ／２×（Ｗ１－Ｗ２）＝Ｄ／２×Ｗ１×（１－１／Γｓ）　・・・（７）
　ここで、Ｗ１＝１．５ＣＡＰとすると、次式が成立する。
　Ｔｓ２＝０．５８７ＣＡＰ　・・・（８） The torque Ts2 required for idling the drive sheave in this test is obtained by the following equation.
Ts2 = D / 2 × (W1-W2) = D / 2 × W1 × (1-1 / Γs) (7)
Here, when W1 = 1.5CAP, the following equation is established.
Ts2 = 0.587CAP (8)
　エレベータ装置の運転状態で必要とされる最大トルクは、非常運転状態を考慮しても式（８）に示したトルクであり、これは非常止め装置の作動確認試験のために必要なトルクに対して７５％程度である。 The maximum torque required in the operation state of the elevator system is the torque shown in the equation (8) even when the emergency operation state is taken into account. This is the torque required for the operation check test of the emergency stop device. About 75%.

The holding force applied to the main rope 8 by the holding force adding device 14 is less than the unbalance load between the car 9 and the counterweight 10. Further, the holding force adding device 14 applies a holding force to the main rope 8 on the counterweight 10 side with respect to the drive sheave 5. Further, the holding force adding device 14 does not add holding force to the main rope 8 in the service state of the elevator device other than during the operation confirmation test of the safety device 13.
　図２は図１の保持力付加装置１４を拡大して示す構成図である。機械台３には、支持部材１５が固定されている。支持部材１５には、固定片１６が固定されている。固定片１６には、主索８に対向する固定側摩擦部材１７が固定されている。また、固定片１６には、複数のガイドロッド１８ａ，１８ｂが立設されている。 FIG. 2 is an enlarged configuration diagram showing the holding force applying device 14 shown in FIG. A support member 15 is fixed to the machine base 3. A fixed piece 16 is fixed to the support member 15. A fixed-side friction member 17 facing the main rope 8 is fixed to the fixed piece 16. The fixed piece 16 is provided with a plurality of guide rods 18a and 18b.
　ガイドロッド１８ａ，１８ｂには、可動片１９が支持されている。可動片１９は、ガイドロッド１８ａ，１８ｂに沿って固定側摩擦部材１７に接離する方向へ変位可能となっている。可動片１９には、主索８に対向する可動側摩擦部材２０が固定されている。ガイドロッド１８ａ，１８ｂには、可動片１９を固定片１６側へ付勢する複数の保持力付与ばね（圧縮ばね）２１ａ，２１ｂが設けられている。 A movable piece 19 is supported on the guide rods 18a and 18b. The movable piece 19 can be displaced in a direction in which the movable piece 19 contacts and separates from the fixed friction member 17 along the guide rods 18a and 18b. A movable friction member 20 facing the main rope 8 is fixed to the movable piece 19. The guide rods 18a and 18b are provided with a plurality of holding force applying springs (compression springs) 21a and 21b for urging the movable piece 19 toward the fixed piece 16 side.
　また、固定片１６と可動片１９との間には、保持力付与ばね２１ａ，２１ｂに抗して可動側摩擦部材２０を固定側摩擦部材１７から離れた状態に保持するストッパ手段（図示せず）が設けられている。保持力付加装置１４は、非常止め装置１３の作動確認試験時に、ストッパ手段を解除することにより、固定側摩擦部材１７と可動側摩擦部材２０との間に主索８を直接把持（挟持）して主索８を摩擦制動することにより主索８に保持力を与える付加ブレーキ（ロープブレーキ）として機能する。 Further, between the fixed piece 16 and the movable piece 19, a stopper means (not shown) that holds the movable friction member 20 away from the fixed friction member 17 against the holding force applying springs 21a and 21b. ) Is provided. The holding force adding device 14 directly grips (pinches) the main rope 8 between the fixed-side friction member 17 and the movable-side friction member 20 by releasing the stopper means during the operation check test of the safety device 13. Thus, the main rope 8 functions as an additional brake (rope brake) that gives a holding force to the main rope 8 by friction braking.
　このように、保持力付加装置１４は、非常止め装置１３の作動確認試験時や運転休止時に作動されるものであり、通常運転時や緊急停止時には作動されないため、通常のブレーキのように電気的に開放・作動する機構を必要としない。このため、ストッパ手段は、手動で操作するような簡素な機構で構成可能である。 As described above, the holding force adding device 14 is operated at the time of the operation check test of the emergency stop device 13 or at the time of operation stop, and is not operated at the time of normal operation or emergency stop. Does not require a mechanism to open and operate. Therefore, the stopper means can be configured with a simple mechanism that is manually operated.
　次に、非常止め装置１３の作動確認試験の方法について説明する。まず、ストッパ手段を解除し、保持力付加装置１４により主索８に保持力を与える。この状態で、かご９が上昇する方向へ巻上機４を手動で運転する。これにより、駆動シーブ５に掛かる釣合おもり１０側の主索８の張力のうち、保持力付加装置１４による保持力分の張力が減少する。 Next, a method for confirming the operation of the safety device 13 will be described. First, the stopper means is released, and the holding force is applied to the main rope 8 by the holding force adding device 14. In this state, the hoisting machine 4 is manually operated in the direction in which the car 9 is raised. Thereby, the tension | tensile_strength for the holding force by the holding force addition apparatus 14 among the tension | tensile_strength of the main rope 8 by the side of the counterweight 10 applied to the drive sheave 5 reduces.
　次に、調速機のロープキャッチを作動させ、非常止め装置１３を作動させる。この後、かご９が下降する方向へ駆動シーブ５を回転させる。そして、駆動シーブ５が空転するかどうかを確認する。 Next, the rope catch of the governor is activated and the emergency stop device 13 is activated. Thereafter, the drive sheave 5 is rotated in the direction in which the car 9 descends. Then, it is confirmed whether the drive sheave 5 is idling.
　このような手順で非常止め装置１３の作動確認試験を行った場合、駆動シーブ５の部分の主索８の張力が減少するため、空転に必要なモータトルクを低減することができ、巻上機４を小形化することができる。 When the operation check test of the emergency stop device 13 is performed in such a procedure, the tension of the main rope 8 in the portion of the drive sheave 5 is reduced, so that the motor torque required for idling can be reduced, and the hoisting machine 4 can be miniaturized.
　例えば、保持力付加装置１４がアンバランス荷重（かご９内に乗客がいない状態では一般的に定格荷重の５０％）の９０％の保持力を有し、かご９の重量を１．５×ＣＡＰとすると、Ｗ２＝２．０ＣＡＰ（ロープ類の重量は省略）であるから、空転に必要なトルクは、次式のように計算され、保持力付加装置１４を用いない場合に対して７７％まで低減できる。
　Ｔｓ１’＝Ｄ／２×Ｗ２’×（１－１／Γｓ）＝Ｄ／２×（Ｗ２－０．５ＣＡＰ×０．９）×（１－１／Γｓ）＝０．６０７ＣＡＰ×Ｄ For example, the holding force adding device 14 has a holding force of 90% of an unbalanced load (generally 50% of the rated load when there is no passenger in the car 9), and the weight of the car 9 is 1.5 × CAP. Then, since W2 = 2.0CAP (the weight of the ropes is omitted), the torque required for idling is calculated as follows, and is up to 77% compared to the case where the holding force adding device 14 is not used. Can be reduced.
Ts1 ′ = D / 2 × W2 ′ × (1-1 / Γs) = D / 2 × (W2-0.5CAP × 0.9) × (1-1 / Γs) = 0.607CAP × D
　なお、保持力付加装置１４がアンバランス荷重以上の保持力を有していると、非常止め装置１３が正常に作動していなくても、保持力付加装置１４の保持力によりかご９の落下を阻止している可能性が発生してしまう。逆に、保持力付加装置１４の保持力がアンバランス荷重未満であれば、巻上機ブレーキを開放した際に釣合おもり１０が下降方向へ移動し、保持力付加装置１４によりかご９を保持していないことを照明できる。 If the holding force adding device 14 has a holding force equal to or greater than the unbalance load, the cage 9 can be dropped by the holding force of the holding force adding device 14 even if the emergency stop device 13 is not operating normally. The possibility of blocking occurs. On the other hand, if the holding force of the holding force adding device 14 is less than the unbalance load, the counterweight 10 moves in the downward direction when the hoisting machine brake is released, and the holding force adding device 14 holds the car 9. You can illuminate what you are not doing.
　実施の形態２．
　次に、図３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側面図、図４は図３の釣合おもり１０を拡大して示す側面図である。この例では、釣合おもり１０の上下に保持力付加装置２２が搭載されている。各保持力付加装置２２の構成は、図２の保持力付加装置１４と同様であるが、固定片１６は釣合おもり１０に固定されている。そして、固定側摩擦部材１７と可動側摩擦部材２０とは、釣合おもりガイドレール１２を挟持するようになっている。 Embodiment 2. FIG.
3 is a side view showing an elevator apparatus according to Embodiment 2 of the present invention, and FIG. 4 is an enlarged side view showing the counterweight 10 in FIG. In this example, holding force adding devices 22 are mounted above and below the counterweight 10. The configuration of each holding force applying device 22 is the same as that of the holding force applying device 14 of FIG. 2, but the fixing piece 16 is fixed to the counterweight 10. The fixed friction member 17 and the movable friction member 20 sandwich the counterweight guide rail 12.
　実施の形態２の保持力付加装置２２は、非常止め装置１３の作動確認試験を行う際に、釣合おもりガイドレール１２を挟持し釣合おもり１０を摩擦制動することにより、アンバランス荷重未満の保持力を、駆動シーブ５よりも釣合おもり１０側で主索８に与える。他の構成及び試験方法は、実施の形態１と同様である。 The holding force adding device 22 according to the second embodiment holds the counterweight guide rail 12 and frictionally brakes the counterweight 10 when the operation check test of the safety device 13 is performed. A holding force is applied to the main rope 8 on the counterweight 10 side of the drive sheave 5. Other configurations and test methods are the same as those in the first embodiment.
　このような構成及び試験方法によっても、駆動シーブ５の部分の主索８の張力が減少するため、空転に必要なモータトルクを低減することができ、巻上機４を小形化することができる。 Also with such a configuration and test method, the tension of the main rope 8 in the drive sheave 5 portion is reduced, so that the motor torque necessary for idling can be reduced and the hoisting machine 4 can be reduced in size. .
　実施の形態３．
　次に、図５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側面図である。図において、そらせ車７には、保持力付加装置２３が設けられている。保持力付加装置２３は、非常止め装置１３の作動確認試験を行う際に、そらせ車７の回転を制動することにより、アンバランス荷重未満の保持力を、駆動シーブ５よりも釣合おもり１０側で主索８に与える。他の構成及び試験方法は、実施の形態１と同様である。 Embodiment 3 FIG.
5 is a side view showing an elevator apparatus according to Embodiment 3 of the present invention. In the figure, the deflecting wheel 7 is provided with a holding force adding device 23. The holding force adding device 23 brakes the rotation of the baffle wheel 7 when performing the operation check test of the emergency stop device 13, so that the holding force less than the unbalance load is on the counterweight 10 side than the drive sheave 5. Then give it to the main rope 8. Other configurations and test methods are the same as those in the first embodiment.
　このような構成及び試験方法によっても、駆動シーブ５の部分の主索８の張力が減少するため、空転に必要なモータトルクを低減することができ、巻上機４を小形化することができる。 Also with such a configuration and test method, the tension of the main rope 8 in the drive sheave 5 portion is reduced, so that the motor torque necessary for idling can be reduced and the hoisting machine 4 can be reduced in size. .
　なお、そらせ車７に対する主索８の巻き付け角度が小さく、そらせ車７の回転を制動しても主索８が滑ることにより必要な効果が得られない場合がある。このような場合、そらせ車７の主索８が挿入される溝面を高摩擦材で構成してもよい。また、そらせ車７の主索８が掛かる部分を直接制動してもよい。即ち、そらせ車７との間に主索８を挟持するようにしてもよい。さらに、非常止め装置１３の作動確認試験を行う際に、主索８のそらせ車７に掛かる部分の外周に高摩擦材を巻き付けてもよい。 Note that the wrapping angle of the main rope 8 with respect to the deflecting wheel 7 is small, and even if the rotation of the deflecting wheel 7 is braked, the necessary effect may not be obtained due to the main rope 8 slipping. In such a case, the groove surface into which the main rope 8 of the deflector wheel 7 is inserted may be made of a high friction material. Moreover, you may brake directly the part on which the main rope 8 of the baffle wheel 7 hooks. That is, the main rope 8 may be sandwiched between the baffle wheel 7. Furthermore, when performing the operation check test of the safety device 13, a high friction material may be wound around the outer periphery of the portion of the main rope 8 that hangs on the deflector 7.
　また、上記の例では、１：１ローピング方式のエレベータ装置を示したが、これに限定されるものではなく、例えば２：１ローピング方式のエレベータ装置にもこの発明は適用できる。 In the above example, the 1: 1 roping type elevator apparatus is shown. However, the present invention is not limited to this. For example, the present invention can also be applied to a 2: 1 roping type elevator apparatus.
