Abstract
Description
本発明は、ガイドレールに案内されて移動する昇降体が、規定以上の速度での移動動作を生じた場合に、昇降体を減速、停止するための安全装置を備えたエレベーター装置に関する。 The present invention relates to an elevator apparatus provided with a safety device for decelerating and stopping a lifting body when the lifting body that is guided by a guide rail moves at a speed higher than a specified speed.
一般に、ロープ式エレベーターにおいては、何らかの故障で昇降体が過速降下した場合に、その速度が定格速度の１．４倍を越えないうちに調速機のガバナロープ掴み動作を介して制動子をガイドレールに押し付け、摩擦力により昇降体を制動するエレベーターの非常止め装置が設けられている。また、昇降路の底部には、かごが衝突しそうになった場合、衝突しないうちにかごの昇降を緩やかに停止させるための緩衝器が設けられている。 In general, in a rope-type elevator, when the lifting body drops excessively due to some failure, the brake is guided through the governor rope gripping operation before the speed exceeds 1.4 times the rated speed. An elevator emergency stop device is provided that presses against the rail and brakes the lifting body by frictional force. In addition, a shock absorber is provided at the bottom of the hoistway to gently stop the raising and lowering of the car before the car is about to collide.
緩衝器によるかごの停止はかごが緩衝器に衝突する状態でなされる。したがって、かごの乗客に与える衝撃を安全な範囲に抑えるために、緩衝器の動作ストロークを一定以上の高さにする必要がある。このことは緩衝器の大型化や高コスト化につながっている。またピットの深さは一般的に動作ストロークの２倍以上必要とされるが、緩衝器の大型化によりピットの深さも深くなりその結果、建築物の利用効率を低下させることになる。 The car is stopped by the shock absorber when the car collides with the shock absorber. Therefore, in order to suppress the impact given to the passenger of the car within a safe range, it is necessary to set the operation stroke of the shock absorber to a certain level or higher. This has led to an increase in the size and cost of the shock absorber. In addition, the depth of the pit is generally required to be twice or more of the operation stroke, but the depth of the pit is increased due to the increase in size of the shock absorber, and as a result, the utilization efficiency of the building is lowered.
そこで、従来、かごを十分に減速させることのできる非常用減速装置を設け、緩衝器に対する負荷をできるだけ小さくして緩衝器の小型化を図り、さらには緩衝器の設置も不要にしたものが提案されている（例えば、特許文献１参照）。この装置は、かごを案内するガイドレールに対してこれを挟み込む状態で係合するように形成された制動挟持体と、ガイドレールの終端部に設けられ、終端方向に向けて厚みが増大する増厚部を有するストッパからなり、制動挟持体がストッパへ進入することでかごの運動エネルギを吸収することにより、非常時の減速をなすようにしたものである。すなわち、制動挟持体をかごに対して固定的に接続させるとともに、この制動挟持体がストッパへ進入することにより増厚部に削れを生じ、この削れによりかごの運動エネルギを吸収するようにしている。 Therefore, it has been proposed to provide an emergency decelerator that can sufficiently decelerate the car, reduce the load on the shock absorber as much as possible to reduce the size of the shock absorber, and eliminate the need for a shock absorber. (For example, refer to Patent Document 1). This device is provided with a brake holding body formed to engage with a guide rail that guides the car in a state in which it is sandwiched, and an end portion of the guide rail, and increases in thickness toward the end direction. It consists of a stopper having a thick part, and the braking sandwiching body enters the stopper to absorb the kinetic energy of the car so as to reduce the emergency speed. That is, the brake sandwiching body is fixedly connected to the car, and when the brake sandwiching body enters the stopper, the thickened portion is scraped to absorb the kinetic energy of the car. .
しかしながら、前述した従来の非常用減速装置では、かご側に、制動挟持体を新たに設ける必要があるとともに、ガイドレールを、その終端部に、終端方向に向けて厚みが増大する増厚部を有するストッパが備えられた特別なものとする必要があり、その製作のためのコスト増加を招くという問題があった。また、従来のものでは、ストッパ部材をガイドレールに着脱自在に取付けることも提案されているが、この場合、制動挟持体がストッパに進入する際にかかる大きな衝撃により、ストッパがガイドレールから脱落する恐れがあり、安全装置としての目的を考えた時に、その信頼性に懸念があった。さらに、従来のものは、それ自身で非常止め装置を構成するものであり、非常止め装置を確実に作動させ、緩衝器に対する負荷をできるだけ小さくして緩衝器の小型化を図り、さらには緩衝器の設置も不要とすることを念頭においたものではない。 However, in the conventional emergency speed reducer described above, it is necessary to newly provide a brake clamping body on the car side, and at the end of the guide rail, a thickened portion that increases in thickness toward the end is provided. There is a problem that it is necessary to provide a special stopper provided with the stopper, which causes an increase in cost for manufacturing the stopper. In addition, in the prior art, it has been proposed that the stopper member is detachably attached to the guide rail, but in this case, the stopper is dropped from the guide rail due to a large impact applied when the braking clamp body enters the stopper. There was a fear, and when considering the purpose as a safety device, there was concern about its reliability. Further, the conventional device constitutes an emergency stop device by itself, and the emergency stop device is operated reliably, the load on the shock absorber is reduced as much as possible, and the shock absorber is reduced in size. It is not intended to eliminate the need for installation.
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、必要時に非常止め装置を確実に作動させることのできるエレベーター装置を提供することにある。 The present invention has been made from the state of the prior art described above, and an object of the present invention is to provide an elevator apparatus that can reliably operate an emergency stop device when necessary.
前記目的を達成するために、本発明は、昇降路を昇降する昇降体と、この昇降体の昇降を案内するガイドレールと、前記昇降体に取付けられ、必要時にガイドレールを強圧することで摩擦力を発生させる非常止め装置と、前記ガイドレールに設けられ、前記昇降体の下降を強制制動する強制作動装置とを備えたエレベーター装置において、前記非常止め装置は、ケース内で引き上げられて前記ガイドレールに摺接する非常止め制動子を、前記強制作動装置は、前記ガイドレールに摺接する制動子と、この制動子を前記ガイドレールに沿って保持する保持手段とを備え、前記強制作動装置を前記非常止め装置の鉛直投影面内に配置し、かつ、前記昇降体の異常下降に伴う前記非常止め装置の前記強制作動装置への当接により、前記非常止め制動子を引き上げて前記ガイドレールを強圧させて前記昇降体を制動することを特徴としている。 In order to achieve the above object, the present invention provides a lifting body that lifts and lowers a hoistway, a guide rail that guides the lifting and lowering of the lifting body, and a friction that is attached to the lifting body and pressurizes the guide rail when necessary. An elevator apparatus comprising: an emergency stop device that generates force; and a forcible operation device that is provided on the guide rail and forcibly brakes the lowering of the elevating body. The elevator device is lifted up in a case and the guide An emergency stop brake that is in sliding contact with a rail, wherein the forcible operating device includes a brake that is in sliding contact with the guide rail, and holding means that holds the brake along the guide rail. The emergency stop braking is arranged by placing the emergency stop device in a vertical projection plane and abutting the emergency stop device with the forced operation device when the lifting body is abnormally lowered. The by strongly pressed to the guide rail by pulling is characterized by braking said lifting body.
このように構成した本発明では、通常時、強制作動装置の制動子は保持手段によりガイドレールに係止するかたちで保持されている。そして、何らかの要因により昇降体が異常下降した場合、所定の高さ位置で昇降体に設けられた非常止め装置と、この非常止め装置の鉛直投影面内に配置された強制作動装置とが当接し、これに応じて非常止め装置の制動子がガイドレールに押し付けられ、その摩擦力により昇降体を制動する。このように、必要時に非常止め装置を確実に作動させ、昇降体の異常下降を制動できる。また、非常止め装置は、安定した制動性能を有するものであるとともに、十分な堅牢性をもってあらかじめ昇降体に設けられるべきものであり、本発明を適用するにあたりそれ自体の構造変更を要さない。さらに、ガイドレールは、非常止め装置の制動子のガイドレールへの摺動により生じる摩擦力により昇降体を制動させるものであることから通常のものを用いることができる。 In the present invention configured as described above, the brake element of the forced operation device is normally held in such a manner as to be locked to the guide rail by the holding means. When the lifting body is abnormally lowered for some reason, the emergency stop device provided on the lifting body at a predetermined height position and the forced operation device arranged in the vertical projection plane of the emergency stop device come into contact with each other. In response to this, the brake element of the emergency stop device is pressed against the guide rail, and the lifting body is braked by the frictional force. In this way, the emergency stop device can be reliably operated when necessary to brake abnormal lowering of the lifting body. Further, the emergency stop device should have a stable braking performance and should be provided in advance in the lifting body with sufficient robustness, and does not require a structural change of itself when applying the present invention. Furthermore, since a guide rail brakes a raising / lowering body with the frictional force which arises by sliding to the guide rail of the brake element of an emergency stop device, a normal thing can be used.
また、本発明は、前記強制作動装置が前記昇降路底部のピットに配置され、前記非常止め装置を、前記昇降体の下部に設けたことを特徴としている。 Further, the present invention is characterized in that the forced operation device is disposed in a pit at the bottom of the hoistway, and the emergency stop device is provided at a lower portion of the hoisting body.
このように構成した本発明では、非常止め装置は昇降体の下部に設けられていて、これと干渉して非常止め装置を作動させる強制作動装置は、ピット底部から所定寸法離れた高さ位置で、非常止め装置を作動させたい位置に保持させればよいので、非常止め装置作動位置を簡単に決定することが可能となる。 In the present invention configured as described above, the emergency stop device is provided at the lower part of the lifting body, and the forcible operation device that operates the emergency stop device by interfering with this is located at a height position away from the pit bottom by a predetermined dimension. Since it is only necessary to hold the emergency stop device at a position where it is desired to operate, it is possible to easily determine the emergency stop device operating position.
また、本発明は、前記保持手段に、前記制動子を前記ガイドレールに押圧する弾性体を備えたことを特徴としている。 Further, the present invention is characterized in that the holding means includes an elastic body that presses the brake element against the guide rail.
このように構成した本発明では、保持手段に備えられた弾性体により強制作動装置の制動子をガイドレールに押し付けることにより、制動時に適切な摩擦力を発生させ、安定した強制制動を実現することができる。 In the present invention configured as described above, by pressing the brake element of the forced operation device against the guide rail by the elastic body provided in the holding means, an appropriate frictional force is generated at the time of braking, and stable forced braking is realized. Can do.
本発明によれば、必要時に非常止め装置を確実に作動させ、昇降体の異常下降を制動できることから、緩衝器に対する負荷をできるだけ小さくして緩衝器の小型化を図り、さらには緩衝器の設置も不要とすることができる。特に、通常の非常止め装置およびガイドレールを使用できることから、緩衝器の小型化および緩衝器レスのエレベーター装置とするためのコスト増加を防止することができる。 According to the present invention, the emergency stop device can be reliably operated when necessary, and the abnormal lowering of the lifting body can be braked. Therefore, the load on the shock absorber can be reduced as much as possible to reduce the size of the shock absorber, and the shock absorber can be installed. Can also be made unnecessary. In particular, since an ordinary emergency stop device and a guide rail can be used, it is possible to prevent a shock absorber from being downsized and an increase in cost for a shock absorber-less elevator device.
以下、本発明に係るエレベーター装置の実施例を図に基づき説明する。 Embodiments of an elevator apparatus according to the present invention will be described below with reference to the drawings.
本実施例のエレベーター装置は、図１に示すように、昇降路１を昇降する昇降体、例えば、かご２と、このかご２の昇降を案内するガイドレール３と、かご２に取付けられ、必要時にガイドレール３を強圧することで摩擦力を発生させる非常止め装置４と、昇降路底部のピット５に配置され、かご２の下降を強制的に制動する強制作動装置６とを備えている。 As shown in FIG. 1, the elevator apparatus according to the present embodiment is attached to a lift body that moves up and down the hoistway 1, such as a car 2, a guide rail 3 that guides the raising and lowering of the car 2, and the car 2. An emergency stop device 4 that generates frictional force by sometimes pressing the guide rail 3 at a time, and a forced operation device 6 that is disposed in the pit 5 at the bottom of the hoistway and forcibly brakes the descent of the car 2 are provided.
かご２には、図示しない巻上機により駆動されるロープ７が接続されるとともに、その四隅には、ガイドレール３に摺接するガイドシュー８が配置されている。 A rope 7 driven by a hoisting machine (not shown) is connected to the car 2, and guide shoes 8 that are in sliding contact with the guide rail 3 are arranged at four corners thereof.
非常止め装置４は、かご２の下部にあってそれぞれのガイドレール３と対向するように設けられるとともに、図２に示すように、各非常止め装置４は、本体ケース４０内にガイドレール３を挟持するように対となって配置される非常止め制動子４１ａ、４１ｂと、異常時に非常止め制動子４１ａ、４１ｂをガイドレール３に摺接させるために本体ケース４０内で非常止め制動子４１ａ、４１ｂを引き上げるための引き上げ部４２と、制動時、非常止め制動子４１に対しガイドレール３方向に向けて押圧力を付与する本体ケース４０に取り付けられた弾性体４３ａ、４３ｂとを有している。 The emergency stop devices 4 are provided at the lower part of the car 2 so as to face the respective guide rails 3, and as shown in FIG. 2, each emergency stop device 4 has the guide rails 3 in the main body case 40. The emergency stop brakes 41a and 41b that are arranged in pairs so as to be sandwiched, and the emergency stop brakes 41a and 41b in the main body case 40 for sliding the emergency stop brakes 41a and 41b to the guide rail 3 in an abnormal state. A lifting portion 42 for lifting 41b, and elastic bodies 43a and 43b attached to a body case 40 for applying a pressing force toward the guide rail 3 toward the emergency stop brake 41 during braking. .
強制作動装置６は、ガイドレール３に摺接する対となる制動子６１ａ、６１ｂと、この制動子６１ａ、６１ｂをガイドレール３に沿って保持する保持手段６２とを備えており、制動子６１ａ、６１ｂは保持手段６２によりガイドレール３に係止するかたちでピット５底部から所定寸法離れた高さ位置に保持されている。また、保持手段６２は、コの字状の断面形状を有しており、その立ち上がり辺とガイドレール３との間で制動子６１ａ、６１ｂを挟み込む本体６２ａと、本体６２ａの立ち上がり辺に架設されるロッド６２ｂと、その中空部にロッド６２ｂが挿通され、一端が一方の制動子６１ｂ、他端がナット６２ｃに当接するように配置され、制動子６１ａ、６１ｂをガイドレール３に押圧する弾性体６２ｄとを備えている。 The forcible operating device 6 includes a pair of brake elements 61a and 61b that are in sliding contact with the guide rail 3, and holding means 62 that holds the brake elements 61a and 61b along the guide rail 3. 61b is held at a height position separated from the bottom of the pit 5 by a holding means 62 so as to be locked to the guide rail 3. The holding means 62 has a U-shaped cross-sectional shape, and is built on a main body 62a that sandwiches the brake elements 61a and 61b between the rising side and the guide rail 3, and on the rising side of the main body 62a. The rod 62b is inserted into the hollow portion of the rod 62b, and one end of the rod 62b is disposed in contact with the brake element 61b and the other end is in contact with the nut 62c. The elastic body presses the brake elements 61a and 61b against the guide rail 3. 62d.
本実施例にあっては、エレベーター装置に適用された強制作動装置６が非常止め装置４の後段で作動することを基本としている。すなわち何らかの故障でかご２が下降した場合の異常時に、その速度が定格速度の１．４倍を越えないうちに図示しない調速機のガバナロープ掴み動作を介し、図４に示すように、非常止め装置４の非常止め制動子４１ａ、４１ｂがガイドレール３に押し付けられ、摩擦力によりかご２を制動する。しかし、昇降路端部で異常下降した場合、非常止め装置４の作動前に、所定の高さ位置でかご２下部に設けられた非常止め装置４と、この非常止め装置４の鉛直投影面内に配置された強制作動装置６とが当接する。本実施例のものでは、図３に示すように、非常止め装置４の非常止め制動子４１ａ、４１ｂ下部と、強制作動装置６の制動子６１ａ、６１ｂ上部とが当接する。この状態でかご２が下降することで、強制作動装置６の制動子６１ａ、６１ｂがガイドレール３との摩擦力により、非常止め装置の非常止め制動子４１ａ、４１ｂをガイドレール３に当接させ、非常止め装置の非常止め制動子４１ａ、４１ｂの摩擦力により、かご２がピット５底部に衝突する前に、かご２を制動する。なお、強制作動装置６の制動子６１ａ、６１ｂとガイドレール３との摩擦係数をμ、弾性体６２ｄが制動子６１ａ、６１ｂをガイドレール３に押圧する力をＮ、非常止め装置４の非常止め制動子４１ａ、４１ｂを引き上げるために要する力をＷ、非常止め装置４と強制作動装置６との当接時に作用する力をＦとした場合、次の数式が成り立つように各部位は設計されている。即ち、Ｆ＝μＮの時、Ｗ＝ＦまたはＷ＜Ｆとなるように設計される。 In the present embodiment, the basic principle is that the forcible operating device 6 applied to the elevator apparatus operates at the rear stage of the emergency stop device 4. That is, in the event of an abnormality when the car 2 is lowered due to some failure, an emergency stop is performed as shown in FIG. 4 through the governor rope gripping operation of the governor (not shown) before the speed exceeds 1.4 times the rated speed. The emergency stop brakes 41a and 41b of the device 4 are pressed against the guide rail 3 to brake the car 2 by frictional force. However, in the case of abnormal lowering at the end of the hoistway, the emergency stop device 4 provided at the lower part of the car 2 at a predetermined height position and the vertical stop plane of the emergency stop device 4 before the operation of the emergency stop device 4 The forcible operating device 6 arranged in the position abuts. In the present embodiment, as shown in FIG. 3, the lower part of the emergency stop brakes 41 a and 41 b of the emergency stop device 4 and the upper part of the brake elements 61 a and 61 b of the forced operation device 6 abut. When the car 2 is lowered in this state, the braking elements 61a and 61b of the forcible operating device 6 cause the emergency braking brake elements 41a and 41b of the emergency locking device to abut against the guide rail 3 by the frictional force with the guide rail 3. The car 2 is braked before the car 2 collides with the bottom of the pit 5 by the frictional force of the emergency stop brakes 41a and 41b of the emergency stop device. Note that the coefficient of friction between the brake elements 61a and 61b of the forced operation device 6 and the guide rail 3 is μ, the force that the elastic body 62d presses the brake elements 61a and 61b against the guide rail 3 is N, and the emergency stop of the emergency stop device 4 is used. Each part is designed so that the following formula is established, where W is the force required to lift the brake elements 41a and 41b, and F is the force acting when the emergency stop device 4 and the forced operation device 6 are in contact with each other. Yes. That is, when F = μN, the design is such that W = F or W <F.
本実施例によれば、強制作動装置６を作動させる非常止め装置４は、十分な堅牢性をもってあらかじめかご２に設けられるべきものであるとともに、ガイドレール３は、非常止め装置４の非常止め制動子４１ａ、４１ｂのガイドレール３への摺動により生じる摩擦力によりかご２を制動させるものであることから、通常のものを用いることができる。したがって、従来同等の安全性を確保した緩衝器レスのエレベーター装置を実現できるとともに、通常の非常止め装置４およびガイドレール３を使用できるためコスト増加の防止が図れる。さらに、保持手段６２に備えられた弾性体６２ｄにより制動子６１ａ、６１ｂをガイドレール３に押し付けることにより、制動時に適切な摩擦力を発生させ、安定した強制制動を実現することができる。 According to the present embodiment, the emergency stop device 4 for operating the forced operation device 6 should be provided in advance in the car 2 with sufficient robustness, and the guide rail 3 is used for the emergency stop braking of the emergency stop device 4. Since the car 2 is braked by the frictional force generated by the sliding of the children 41a and 41b to the guide rail 3, a normal one can be used. Therefore, it is possible to realize a shock absorber-less elevator device that ensures the same safety as that of the prior art, and the normal emergency stop device 4 and guide rail 3 can be used, thereby preventing an increase in cost. Furthermore, by pressing the brake elements 61a and 61b against the guide rail 3 by the elastic body 62d provided in the holding means 62, it is possible to generate an appropriate frictional force during braking and to realize stable forced braking.
なお、強制作動装置６は、弾性体６２ｄによって、制動子６１ａ，６１ｂが発生する摩擦力を調整することができる。つまり、制動子６１ａ，６１ｂによって非常止め装置４を強制作動させるとともに、強制作動装置６は非常止め装置４が動作することでかご２が減速しながら停止するまで、かご２と一緒に非常止め装置４を強制作動させながらガイドレール３上を下降し続けることが可能なので、かご２が急停止して、大きな衝撃がかご２内の乗客に加わることも防止できる。 The forcible operating device 6 can adjust the frictional force generated by the brake elements 61a and 61b by the elastic body 62d. That is, the emergency stop device 4 is forcibly operated by the brake elements 61a and 61b, and the forced operation device 6 is operated together with the car 2 until the car 2 is stopped while decelerating due to the operation of the emergency stop device 4. Since it is possible to continue descending on the guide rail 3 while forcibly operating 4, it is possible to prevent the car 2 from stopping suddenly and applying a large impact to passengers in the car 2.
なお、前述した実施例では、かご２に非常止め装置４を設け、この非常止め装置４を強制作動装置６で作動させるものを例としたが、本発明はこれに限らず、つり合いおもり側にも同等の構成の非常止め装置を設け、この非常止め装置を強制作動させる強制作動装置を設けてもよい。また、ピット５に緩衝器を設置しないものを例としたが、ピット５に小型の緩衝器を設けてもよい。 In the above-described embodiment, the car 2 is provided with the emergency stop device 4 and the emergency stop device 4 is operated by the forced operation device 6. However, the present invention is not limited to this, and the balance weight side is provided. Alternatively, an emergency stop device having the same configuration may be provided, and a forced operation device for forcibly operating the emergency stop device may be provided. Moreover, although the thing which does not install a shock absorber in the pit 5 was taken as an example, a small shock absorber may be provided in the pit 5.
