Description

この発明はエレベータ装置に関し、特に釣り合いおもり用のガイドレールの上端部近傍におけるオーバヘッド寸法の縮小化に関するものである。   The present invention relates to an elevator apparatus, and more particularly to reduction of overhead dimensions in the vicinity of the upper end portion of a counterweight guide rail.

従来のいわゆる機械室レスエレベータのレイアウトについては、例えば特開２０００−９５４６２号公報（特許文献１）に、エレベータの設置スペースをより小さくして建物の利用効率を上げたものが開示されている。この例では昇降路頂部の機械室を省略して、しかもオーバヘッド寸法（最上階から昇降路天井までの寸法）、およびピット寸法（最下階から昇降路底部までの寸法）、また昇降路の平面の間口、奥行き寸法を小さくして省スペース化を図ることが示されている。以下、この発明の特徴部分を明確にするために、図１６、及び図１７を用いて従来装置をより具体的に説明する。   As for the layout of a conventional so-called machine room-less elevator, for example, Japanese Patent Application Laid-Open No. 2000-95462 (Patent Document 1) discloses a structure in which the installation space of the elevator is further reduced to increase the use efficiency of the building. In this example, the machine room at the top of the hoistway is omitted, and overhead dimensions (the dimension from the top floor to the hoistway ceiling) and pit dimensions (dimensions from the bottom floor to the hoistway bottom), and the plane of the hoistway It is shown that the frontage and depth dimensions are reduced to save space. Hereinafter, in order to clarify the characterizing portion of the present invention, the conventional apparatus will be described more specifically with reference to FIGS. 16 and 17.

上記のような従来装置では、図に示すように、かご１の側面部に釣り合いおもり４、おもり側返し車７、かご側返し車８、及び巻上機綱車１０などを配置する関係上、おもり側返し車７が、釣り合いおもり４用のガイドレール５の内、昇降路２手前側（図１６の左側）のガイドレール５ａの頂部に配置されるため、ガイドレール５ａをおもり側返し車７に当たらないように該おもり側返し車７の手前で止めなければならない。   In the conventional apparatus as described above, as shown in the drawing, the counterweight 4, the weight-side return wheel 7, the car-side return wheel 8, the hoisting machine sheave 10, and the like are arranged on the side surface of the car 1. Since the weight-side return wheel 7 is disposed at the top of the guide rail 5a on the front side of the hoistway 2 (left side in FIG. 16) in the guide rail 5 for the counterweight 4, the guide rail 5a is placed on the weight-side return wheel 7 It must be stopped in front of the weight-turning wheel 7 so as not to hit.

即ち、釣り合いおもり４に枢着されたおもり吊り車６に巻き付けられた巻上ロープ１１を、昇降路２の頂部に配置されたおもり側返し車７に掛けるわけであるが、昇降路手前側のガイドレール５ａの上におもり側返し車７が配置されるため、ガイドレール５ａの上端部はおもり側返し車７と干渉しない位置までの長さで止める必要がある。また釣り合いおもり４の上部にはガイドシュー４１や給油器４２などが取り付けられており、非常時等に、例えばかご１がピット１３ヘ突き下げた場合、釣り合いおもり４もその分、頂部へ行き過ぎるので、ガイドレール５の上端部はその場合でもガイドシュー４１や給油器４２などが外れない長さが必要であり、そのマージンとして図１６のＨｍで示す余裕寸法が予め確保されている。なお、９はかご１の底部に枢着されたかご吊り車、１２はかご側綱止め、Ｈｏはオーバヘッド寸法を示す。   That is, the hoisting rope 11 wound around the weight suspension vehicle 6 pivotally attached to the counterweight 4 is hung on the weight side return wheel 7 disposed at the top of the hoistway 2. Since the weight side return wheel 7 is disposed on the guide rail 5a, it is necessary to stop the upper end of the guide rail 5a at a length that does not interfere with the weight side return wheel 7. In addition, a guide shoe 41 and a fueling device 42 are attached to the upper part of the counterweight 4, and when the car 1 is pushed down to the pit 13 in an emergency, for example, the counterweight 4 goes too far to the top. In this case, the upper end of the guide rail 5 needs to have such a length that the guide shoe 41 and the oil filler 42 cannot be removed, and a margin dimension indicated by Hm in FIG. 16 is secured in advance as the margin. In addition, 9 is a car suspension wheel pivotally attached to the bottom of the car 1, 12 is a car side rope stop, and Ho is an overhead dimension.

特開２０００−９５４６２号公報（第３頁、図１）JP 2000-95462 A (page 3, FIG. 1)

上記のように、従来のエレベータ装置においては、釣り合いおもり４用のガイドレール５の内、昇降路２手前側のガイドレール５ａの延長線がおもり側返し車７と干渉する位置にあるため、ガイドシュー４１や給油器４２が外れないレール長さとするために図１７のＨｍで示す余裕寸法を確保する必要があり、それだけオーバヘッド寸法Ｈｏが大きくなるという問題があった。   As described above, in the conventional elevator apparatus, the extension line of the guide rail 5a on the near side of the hoistway 2 in the guide rail 5 for the counterweight 4 is in a position where it interferes with the weight-side return wheel 7. In order to make the rail length such that the shoe 41 and the oil filler 42 do not come off, it is necessary to secure a margin dimension indicated by Hm in FIG. 17, and there is a problem that the overhead dimension Ho is increased accordingly.

この発明は、上記のような従来装置の問題点を解決するためになされたもので、昇降路頂部のおもり側返し車と釣り合いおもり用のガイドレールが干渉しないように構成することにより、ガイドレール頂部を短く切る必要がなく、オーバヘッド寸法を小さくすることができるエレベータ装置を提供することを目的とするものである。   The present invention has been made to solve the above-described problems of the conventional device, and is constructed such that the weight-side return wheel at the top of the hoistway and the guide rail for counterweight do not interfere with each other.

上記構成の実施の形態５によれば、おもり側返し車７とガイドレール５ａは完全に逃げるので、上記実施の形態１と同様の効果が得られ、しかもガイドレール５ａを釣り合いおもり４の側面部に設けたため、昇降路２の奥行き方向のレール当面間隔を小さくすることが可能となり、ガイドレール５ａ、５ｂと、その取り付け用のブラケット５１ａ、５１ｂを含めた図の左右方向の奥行き方向寸法を、釣り合いおもり４の奥行き寸法より小さく納めることができ、昇降路２の奥行き方向のスペースをより小さくできる効果も得られる。   According to the fifth embodiment having the above configuration, the weight-side return wheel 7 and the guide rail 5a completely escape, so that the same effect as in the first embodiment can be obtained, and the guide rail 5a is connected to the side surface portion of the counterweight 4. Therefore, it is possible to reduce the distance between the rails in the depth direction of the hoistway 2, and the depth direction dimensions in the horizontal direction in the drawing including the guide rails 5a and 5b and the brackets 51a and 51b for mounting the guide rails 5a and 51b are as follows. The depth of the counterweight 4 can be accommodated smaller, and the effect that the space in the depth direction of the hoistway 2 can be further reduced can be obtained.

実施の形態６．
図１４及び図１５はこの発明の実施の形態６によるエレベータ装置の要部を示すもので、図１４は昇降路上部の要部構成を示す平面図、図１５は図１４の釣り合いおもり部分の詳細を示す平面図である。図示のように本実施の形態６では、釣り合いおもり４を略Ｌ字形状にして略直角を成す外側の２辺が昇降路２の奥コーナ部に沿うように配設し、一対のガイドレール５ａ、５ｂを該釣り合いおもり４のＬ字の端部相互を結ぶ略対角線上に配置したものである。その他の構成は上記実施の形態４と同様であるので説明を省略する。 Embodiment 6 FIG.
14 and 15 show the main part of an elevator apparatus according to Embodiment 6 of the present invention. FIG. 14 is a plan view showing the main part structure of the upper part of the hoistway, and FIG. 15 shows the details of the counterweight part of FIG. FIG. As shown in the figure, in the sixth embodiment, the counterweight 4 is formed in a substantially L shape and arranged on the outer corners of the hoistway 2 so that the two outer sides that are substantially perpendicular to each other are arranged along the rear corner of the hoistway 2. 5b is arranged on a substantially diagonal line connecting the L-shaped ends of the counterweight 4. Since other configurations are the same as those of the fourth embodiment, description thereof is omitted.

上記のように構成された実施の形態５においては、おもり側返し車７とガイドレール５ａの干渉はなく、上記実施の形態１と同様の効果が得られ、しかも昇降路２の奥隅部の空間にＬ字型の釣り合いおもり４を配設したことにより昇降路スペースを有効に利用できる効果も得られる。   In the fifth embodiment configured as described above, there is no interference between the weight-side return wheel 7 and the guide rail 5a, and the same effect as in the first embodiment can be obtained. By arranging the L-shaped counterweight 4 in the space, an effect that the hoistway space can be effectively used is also obtained.

なお、上記実施の形態１〜６で説明したエレベータ装置は、釣り合いおもり用のガイドレール５と、おもり側返し車７とが相互に干渉しないようにしたものの例に過ぎず、必ずしもこれら例示したもののみに限定されるものではなく、それらの配置、形状等を適宜に変更したものでも同様の効果が期待できることは言うまでもない。   In addition, the elevator apparatus demonstrated in the said Embodiment 1-6 is only an example of what prevented the guide rail 5 for counterweights, and the weight side return wheel 7 from mutually interfering, These are not necessarily what was illustrated. It is needless to say that the same effect can be expected even if the arrangement, shape, and the like thereof are appropriately changed.
