Description

本発明は、地震、又は屋外用エレベータにあって風等による主ロープの揺れを抑制するエレベータの主ロープ振れ止め装置に関するものである。   The present invention relates to a main rope steadying device for an elevator that suppresses shaking of a main rope due to wind or the like in an earthquake or outdoor elevator.

一般に、高層建築物にあっては、建築物自体が地震の揺れに対応して変位する耐震構造、即ち柔構造をとっているため、地震の際にはエレベータの昇降路、及びこの昇降路に延設され昇降体を懸架する主ロープにも揺れが生じる。又、屋外エレベータにあっては、特に昇降距離が長くなると、主ロープが風によって煽られて揺れが生じる。このように主ロープに揺れが生じると、主ロープが昇降路内に設置される種々の機器に接触して運転不能になる恐れがあることから、主ロープの横揺れ抑制するエレベータの主ロープ振れ止め装置が提案されている。   Generally, in a high-rise building, since the building itself has an earthquake-resistant structure that is displaced in response to an earthquake shake, that is, a flexible structure, in the event of an earthquake, the elevator hoistway and this hoistway The main rope that extends and suspends the lifting body also sways. In the case of outdoor elevators, especially when the lifting distance is long, the main rope is swayed by the wind and shakes. If swinging occurs in the main rope in this way, the main rope may come into contact with various devices installed in the hoistway and become inoperable. Stop devices have been proposed.

従来、この種のエレベータの主ロープ振れ止め装置として、乗かご上部に載置され、エレベータ用の主ロープが挿通される主ロープ振れ止め体、及び昇降路側に設けられ主ロープ振れ止め体を支持する受台を１組設け、主ロープの揺れを抑制するものがある（例えば、特許文献１参照）。   Conventionally, as a main rope steadying device for this type of elevator, the main rope steadying body mounted on the upper part of the car and through which the main rope for elevator is inserted, and the main rope steadying body provided on the hoistway side are supported. One set of receiving bases is provided to suppress the swing of the main rope (for example, see Patent Document 1).

また、エレベータ用の主ロープが挿通される複数の主ロープ振れ止め体のそれぞれをサブロープで連結し、又、サブロープを自動巻き取りする自動巻き取り装置を備えたものがある（例えば、特許文献２参照）。
特開平４−１２７７７９号公報（第２頁、第１図） 特開２００４−５９２０８号公報（段落番号００１６〜００３２、第１図、第２図） In addition, there is an apparatus provided with an automatic winding device that connects each of a plurality of main rope steady rests through which an elevator main rope is inserted with a sub rope and automatically winds up the sub rope (for example, Patent Document 2). reference).
Japanese Patent Laid-Open No. 4-1277779 (page 2, FIG. 1) Japanese Unexamined Patent Publication No. 2004-59208 (paragraph numbers 0016 to 0032, FIGS. 1 and 2)

前述した従来の前者のエレベータの主ロープ振れ止め装置は、１組の主ロープ振れ止め体、及び受台により主ロープの揺れを抑制するものであるが、近年多く見られる昇降距離が長い高層建築物にあっては、主ロープの揺れを効果的に抑制することが難しいという問題がある。また、後者のエレベータの主ロープ振れ止め装置では、サブロープにより複数の主ロープ振れ止め体を懸架すると共に、サブロープの撓みを防止するために自動巻き取り装置を別途備えたものとしているが、装置の部品点数が多くなり設置コスト及び設置スペースの観点で問題があった。   The conventional former main rope steadying device of the elevator described above is a high-rise building with a long lifting distance that is often seen in recent years, although it suppresses the shaking of the main rope by a set of main rope steadying bodies and a cradle. There is a problem that it is difficult to effectively suppress the swing of the main rope. Further, in the latter main rope steadying device for elevators, a plurality of main rope steadying members are suspended by the sub rope, and an automatic winding device is separately provided to prevent the sub rope from bending. There was a problem in terms of installation cost and installation space because the number of parts increased.

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、簡易な構造で、昇降距離の長いエレベータの主ロープの揺れを抑制することのできるエレベータの主ロープ揺れ止め装置を提供することにある。   The present invention has been made from the above-described actual state of the prior art, and an object thereof is to provide an elevator main rope swaying device capable of suppressing the swaying of the elevator main rope having a simple ascending / descending distance. There is to do.

前記目的を達成するために、本発明は、昇降路を昇降する乗かごの上部に載置され、エレベータ用の主ロープが挿通されるロープ振れ止め体、及び前記昇降路側に配設され、前記ロープ振れ止め体を所定位置で支持可能な受台をそれぞれ複数備えたエレベータの主ロープ振れ止め装置において、前記ロープ振れ止め体それぞれの長手方向の間隔寸法を、上部から下部に向かって短くなるように設定し、かつ、前記受台間の間隔寸法を、最下部の受台間の間隔寸法は、前記乗かごの幅寸法より大きく、最下部のロープ振れ止め体の長手方向の間隔寸法より小さくし、上部の受台間の間隔寸法は、この受台の下方に位置するロープ振れ止め体の長手方向の間隔寸法より大きく、この受台に支持されるロープ振れ止め体の長手方向の間隔寸法より小さくし、前記受台に設けられ前記ロープ振れ止め体との衝突時の衝撃を緩衝する緩衝材と、前記ロープ振れ止め体に設けられ前記緩衝材と係合する位置ずれ防止体を設けたことを特徴としている。 In order to achieve the above object, the present invention is placed on the upper part of a car that moves up and down a hoistway, and is provided on a rope steadying body through which a main rope for an elevator is inserted, and disposed on the hoistway side, In a main rope steadying device for an elevator provided with a plurality of cradles each capable of supporting a rope steadying body at a predetermined position, the distance between the rope steadying bodies in the longitudinal direction is shortened from the top to the bottom. And the interval between the cradle is set such that the interval between the lower cradle is larger than the width of the car and smaller than the interval in the longitudinal direction of the lower rope steady rest. The distance between the upper pedestals is larger than the distance in the longitudinal direction of the rope steady rest located below the rest, and the distance in the longitudinal direction of the rope steady supported by the pedestal. Smaller Comb, a buffer material for buffering the impact at the time of collision with the rope steadying member provided in the cradle, in that a displacement prevention member engaging said cushioning material is provided on the rope bracing member It is a feature.

このように構成した本発明では、ロープ振れ止め体それぞれの長手方向の間隔寸法を、上部から下部に向かって短くなるように設定し、かつ、前記受台間の間隔寸法を、最下部の受台間の間隔寸法は、前記乗かごの幅寸法より大きく、最下部のロープ振れ止め体の長手方向の間隔寸法より小さくし、上部の受台間の間隔寸法は、この受台の下方に位置するロープ振れ止め体の長手方向の間隔寸法より大きく、この受台に支持されるロープ振れ止め体の長手方向の間隔寸法より小さくしてある。これによって、昇降路にあって乗かごの上部に載置された複数のロープ振れ止め体は、乗かごの下降に応じて、最上部に位置するロープ振れ止め体から順次、それぞれの対応する受台に係合することにより昇降路の所定位置に配置され、主ロープの揺れを抑制する。一方、昇降路下方から乗かごが上昇することに応じて、最下部に位置するロープ振れ止め体から順次、乗かご上部に重なるようにして載置されていく。このように対となるロープ振れ止め体及び受台を、他の対となるロープ振れ止め体及び受台と異なる間隔寸法に配設するという簡易な構造で、乗かごの昇降に同期して複数のロープ振れ止め体を昇降路の所定位置に配置することができる。又、複数のロープ振れ止め体により主ロープの揺れを抑制することから、昇降距離の長いエレベータにも対応することができる。   In the present invention configured as described above, the distance between the rope steady rests in the longitudinal direction is set so as to become shorter from the upper part toward the lower part, and the distance between the cradles is set at the lowermost receiving part. The distance between the bases is larger than the width of the car and smaller than the distance between the bottom of the rope steady rests, and the distance between the upper bases is located below the base. It is larger than the distance dimension in the longitudinal direction of the rope steady rest, and smaller than the distance dimension in the longitudinal direction of the rope steady rest supported by the cradle. As a result, the plurality of rope steady rests placed on the upper part of the car in the hoistway are sequentially received from the rope steady rest located at the top in accordance with the lowering of the car. By engaging with the base, it is arranged at a predetermined position of the hoistway and suppresses the swing of the main rope. On the other hand, as the car rises from the lower part of the hoistway, the rope steadying body located at the lowermost part is sequentially placed so as to overlap the upper part of the car. In this way, a simple structure in which the pair of rope steady rests and cradles are arranged at different intervals from the other pair of rope steady rests and cradles, and a plurality of them are synchronized with the raising and lowering of the car. The rope steady rest can be arranged at a predetermined position of the hoistway. In addition, since the main rope is prevented from shaking by the plurality of rope steadying bodies, it is possible to cope with an elevator having a long lifting distance.

本発明によれば、対となるロープ振れ止め体及び受台を、他の対となるロープ振れ止め体及び受台と異なる間隔寸法に配設するという簡易な構造で、乗かごの昇降に同期して複数のロープ振れ止め体を昇降路の所定位置に配置することができることから、設置コストの低減を図ることができると共に、装置の占有スペースを必要最低限とすることができる。又、複数のロープ振れ止め体により主ロープの揺れを抑制することから、昇降距離の長いエレベータにも対応可能なものとし、主ロープの揺れに伴う機器の損傷、及び故障を防ぐことができる。   According to the present invention, the pair of rope steady rests and the pedestal are arranged in a different interval from the other pair of rope steady rests and the pedestal, and are synchronized with the raising and lowering of the car. Since a plurality of rope steadying bodies can be arranged at predetermined positions in the hoistway, the installation cost can be reduced and the space occupied by the apparatus can be minimized. Moreover, since the swing of the main rope is suppressed by the plurality of rope steadying bodies, it is possible to cope with an elevator with a long lifting distance, and it is possible to prevent damage and failure of the equipment due to the swing of the main rope.

本実施形態にあっては、昇降路１にあって乗かご２の上部に載置された複数のロープ振れ止め体４〜６は、乗かご２の下降に応じて図１に示すように、まず、最上ロープ振れ止め体６が昇降路２の最上受台９に係合することにより、最上ロープ振れ止め体６は昇降路２の所定位置に配置される。このとき、緩衝材１８、２１が互いに当接することにより、係合部６ａと最上受台９との衝突による衝撃が緩衝されることから不快な音、及び振動の発生を防ぐことができる。次いで、乗かご２がさらに下降すると、中間ロープ振れ止め体５が昇降路２の中間受台８に係合することにより、中間ロープ振れ止め体５は昇降路２の所定位置に配置される。この後、乗かご２がさらに下降すると、最下ロープ振れ止め体４の係合部４ａが昇降路２の最下受台７に係合することにより、最下ロープ振れ止め体４は昇降路２の所定位置に配置される。このように乗かご２が昇降路１の下方に位置することにより、主ロープ３が昇降路１のほぼ全長に亘って垂下され、地震、或いは屋外エレベータにあっては風の影響を受けやすい状態となっても、複数のロープ振れ止め体４〜６によりその横揺れが抑制される。   In this embodiment, as shown in FIG. 1, the plurality of rope steady rests 4 to 6 placed on the upper part of the car 2 in the hoistway 1, as shown in FIG. First, when the uppermost rope steadying member 6 is engaged with the uppermost receiving base 9 of the hoistway 2, the uppermost rope steadying member 6 is disposed at a predetermined position of the hoistway 2. At this time, the shock-absorbing materials 18 and 21 are brought into contact with each other, so that the impact caused by the collision between the engaging portion 6a and the uppermost receiving base 9 is buffered, so that unpleasant noise and vibration can be prevented. Next, when the car 2 is further lowered, the intermediate rope steadying member 5 is engaged with the intermediate receiving base 8 of the hoistway 2 so that the intermediate rope steadying member 5 is disposed at a predetermined position of the hoistway 2. Thereafter, when the car 2 further descends, the engaging portion 4a of the lowermost rope steadying body 4 engages with the lowermost pedestal 7 of the hoistway 2, so that the lowermost rope steadying body 4 becomes the hoistway. 2 are arranged at predetermined positions. Since the car 2 is positioned below the hoistway 1 in this way, the main rope 3 is suspended over almost the entire length of the hoistway 1 and is easily affected by wind in an earthquake or outdoor elevator. Even if it becomes, the rolling is suppressed by the several rope steadying bodies 4-6.

一方、昇降路１下方から乗かご２が上昇することに応じて、まず、図５に示すように最下ロープ振れ止め体４が乗かご２と係合することにより、乗かご２上部へ載置される。このとき緩衝材１０、１１が互いに当接することにより乗かご２と最下ロープ振れ止め体４との衝突による衝撃が緩衝されることから不快な音、及び振動の発生を防ぐことができる。次いで、乗かご２がさらに上昇すると、中間ロープ振れ止め体５が乗かご２上部、即ち最下ロープ振れ止め体４上部へ載置される。そして、さらなる乗かご２の上昇に応じて最上ロープ振れ止め体６が中間ロープ振れ止め体５に重なるようにして乗かご２上部に載置される。   On the other hand, when the car 2 rises from below the hoistway 1, first, the lowermost rope steady rest 4 is engaged with the car 2 as shown in FIG. Placed. At this time, the shock absorbers 10 and 11 come into contact with each other, so that the shock caused by the collision between the car 2 and the lowermost rope steady rest 4 is buffered, so that unpleasant noise and vibration can be prevented. Next, when the car 2 further rises, the intermediate rope steady rest 5 is placed on the top of the car 2, that is, on the bottom of the bottom rope steady rest 4. Then, as the car 2 further rises, the uppermost rope steady rest 6 is placed on the top of the car 2 so as to overlap the intermediate rope steady rest 5.

このように構成した本実施形態によれば、対となるロープ振れ止め体４〜６及び受台７〜９を、他のロープ振れ止め体及び受台と間隔寸法が異なるように配設するという簡易な構造で、乗かご２の昇降に同期して複数のロープ振れ止め体４〜６を昇降路１の所定位置に配置することができることから、設置コストの低減を図ることができると共に、装置の占有スペースを必要最小限とすることができる。又、複数のロープ振れ止め体４〜６により主ロープ３の揺れを抑制することから、昇降距離の長いエレベータにも対応可能なものとし、主ロープ３の揺れに伴う機器の損傷、及び故障を防ぐことができる。   According to the present embodiment configured as described above, the paired rope steady rests 4 to 6 and the pedestals 7 to 9 are arranged so as to have different spacing dimensions from other rope steady rests and the pedestals. Since a plurality of rope steadying bodies 4 to 6 can be arranged at predetermined positions on the hoistway 1 in synchronization with the raising and lowering of the car 2, the installation cost can be reduced and the device can be reduced. The occupation space can be minimized. In addition, since the main rope 3 is restrained from swinging by the plurality of rope steadying bodies 4 to 6, it is possible to cope with an elevator having a long lifting distance, and damage and failure of the equipment accompanying the swing of the main rope 3 are prevented. Can be prevented.

尚、本実施形態ではロープ振れ止め体の数を、最下ロープ振れ止め体４、中間ロープ振れ止め体５、及び最上ロープ振れ止め体６の３つとしたが、エレベータの昇降距離に応じて任意にその個数を変えることができることは云うまでもない。   In this embodiment, the number of the rope steady rests is three, that is, the bottom rope steady rest 4, the intermediate rope steady rest 5, and the top rope steady rest 6. It goes without saying that the number can be changed.

又、位置ずれ防止体をロープ振れ止め体の側部に設けたが、緩衝体１１，１３，１５部分に設け、緩衝体１０，１２，１４と係合するようにしても良い。 Moreover, although the position shift prevention body is provided on the side portion of the rope steadying body, it may be provided in the buffer bodies 11, 13, and 15 so as to engage with the buffer bodies 10, 12, and 14.
