Description

この発明は、昇降路の固定部又は昇降体に主索の端部を連結するエレベーター主索の引き止め具に関する。   The present invention relates to an elevator main rope retainer for connecting an end portion of a main rope to a fixed portion or a lifting body of a hoistway.

従来のエレベーター主索の引き止め具においては、ソケットにテーパー状空所が設けられてソケットのテーパー状空所の大径側がエレベーターの昇降体側に配置される。そして、ソケットのテーパー状空所の小径側にエレベーターの主索が挿通され、主索がソケットのテーパー状空所内で屈曲されてループ状部が形成される。   In a conventional elevator main rope retainer, the socket is provided with a tapered cavity, and the large-diameter side of the socket's tapered cavity is disposed on the elevator body side. Then, the main rope of the elevator is inserted into the small diameter side of the tapered space of the socket, and the main rope is bent in the tapered space of the socket to form a loop portion.

そして、屈曲部の先端がソケット外に引き出される。また、ソケット内において主索の屈曲部によって形成されたループ状部の空所に楔材が嵌合されて、楔材の先細側がソケットのテーパー状空所の小径側に配置される。この状態で、主索及び楔材がソケットのテーパー状空所の小径側に押し付けられて、主索がソケットに連結される。また、ソケット外で主索の挿通部側と屈曲部の先端側がクリップによって相互に締結される。   And the front-end | tip of a bending part is pulled out of a socket. In addition, a wedge material is fitted into a space of a loop-shaped portion formed by a bent portion of the main rope in the socket, and a tapered side of the wedge material is arranged on a small diameter side of the tapered space of the socket. In this state, the main rope and the wedge material are pressed against the small diameter side of the tapered space of the socket, and the main rope is connected to the socket. Further, the insertion portion side of the main rope and the distal end side of the bent portion are fastened to each other by a clip outside the socket.

従来のエレベーター主索の引き止め具は上記のように構成され、ソケットのテーパー状空所の大径側に係合されたねじ棒を介して、ソケットがエレベーターのかご等の昇降体に連結され、主索によって昇降体を吊持するように構成されている。(例えば、特許文献1参照)。   The conventional elevator main rope retainer is configured as described above, and the socket is connected to a lifting body such as an elevator car via a screw rod engaged with the large-diameter side of the tapered cavity of the socket, The lifting / lowering body is suspended by the main rope. (For example, refer to Patent Document 1).

実開昭59−30067号公報(第6図)Japanese Utility Model Publication No. 59-30067 (Fig. 6)

従来のエレベーター主索の引き止め具では、主索がソケットのテーパー状空所内で屈曲されてループ状部が形成される。このため、ソケットの幅寸法が増し複数本の主索を並列に配置する場合に、エレベーターの昇降路固定部又は昇降体に主索を連結する水平方向のスペースが不足して主索の吊設が制約されたり、昇降体が昇降路端に接近したときに鉛直線に対する主索の傾斜角が増大することによる支障が発生したりするという問題点があった。   In the conventional elevator main rope retainer, the main rope is bent in the tapered space of the socket to form a loop portion. For this reason, when the width of the socket is increased and a plurality of main ropes are arranged in parallel, there is not enough space in the horizontal direction to connect the main rope to the elevator hoistway fixing part or elevator body, and the main rope is suspended. There is a problem that there is a problem that when the hoisting body is restricted or the inclination angle of the main rope with respect to the vertical line increases when the lifting body approaches the end of the hoistway.

この発明は、かかる問題点を解消するためになされたものであり、幅の狭いソケットによって構成されたエレベーター主索の引き止め具を得ることを目的とする。   The present invention has been made to solve such problems, and an object of the present invention is to obtain an elevator main rope retainer constituted by a narrow socket.

この発明に係るエレベーター主索の引き止め具においては、テーパー状空所が設けられてテーパー状空所の小径側にエレベーターの主索が挿通されたソケットと、テーパー状空所内に配置されて先細側がテーパー状空所の小径側に配置され、かつテーパー状空所の横断面において主索を中心とし配置されて、一側が主索側面に接し他側はテーパー状空所内面に対向して装備された複数の楔片とが設けられる。   In the elevator main rope detent according to the present invention, a tapered cavity is provided, and a socket in which the elevator main rope is inserted on the small diameter side of the tapered cavity, and the tapered side is disposed in the tapered cavity. It is arranged on the small diameter side of the tapered cavity and is arranged around the main rope in the cross section of the tapered cavity, with one side touching the main rope side and the other side facing the inner surface of the tapered cavity. And a plurality of wedge pieces.

この発明は以上説明したように、テーパー状空所が設けられてテーパー状空所の小径側にエレベーターの主索が挿通されたソケットと、テーパー状空所内に配置されて先細側がテーパー状空所の小径側に配置され、かつテーパー状空所の横断面において主索を中心とし対向して配置されて、一側が主索側面に接し他側はテーパー状空所内面に対向して装備された複数の楔片とを設けたものである。   As described above, the present invention has a socket in which a tapered space is provided and the main rope of the elevator is inserted on the small diameter side of the tapered space, and a tapered space in which the tapered side is disposed in the tapered space. It is arranged on the small-diameter side of the taper, and is arranged facing the main rope in the cross section of the tapered cavity, with one side touching the side of the main rope and the other side facing the inner surface of the tapered cavity. A plurality of wedge pieces are provided.

これによって、主索がソケットのテーパー状空所に小径側から挿通され、互いに対向した楔片の相互間に配置され、楔片がソケットのテーパー状空所の小径側に押し込まれて、ソケットと主索とが結合される。この構成によって、ソケットの幅を狭くすることができ複数本の主索を並列に配置する場合に、エレベーターの昇降路固定部又は昇降体に主索を連結する水平方向のスペースが少ないときであっても主索の張設を容易化する効果がある。また、主索に吊持された昇降体が昇降路端に接近したときに鉛直線に対する主索の傾斜角が増大することによる支障の発生を未然に防止する効果がある。   As a result, the main rope is inserted into the tapered cavity of the socket from the small diameter side and is disposed between the wedge pieces facing each other, and the wedge piece is pushed into the small diameter side of the tapered cavity of the socket, The main rope is combined. With this configuration, when the width of the socket can be reduced and a plurality of main ropes are arranged in parallel, the horizontal space for connecting the main ropes to the elevator hoistway fixing part or the elevator body is small. However, there is an effect of facilitating the extension of the main rope. Further, there is an effect of preventing the occurrence of trouble due to an increase in the inclination angle of the main rope with respect to the vertical line when the lifting body suspended by the main rope approaches the end of the hoistway.

The wedge pieces 6 are arranged to face each other, one side of each wedge piece 6 is in contact with the side surface of the main rope 3 and the other side is arranged in contact with the inner surface of the tapered cavity 2. In addition, on each side surface of each wedge piece 6 facing each other on the main rope 3 side, an engaging portion 7 made up of a plurality of projecting teeth is provided.

また、小径側からソケット1のテーパー状空所2に挿通された主索3は、互いに対向した楔片6の相互間を経てテーパー状空所2内で屈曲される。そして、その先端が主索引き出し孔5からソケット1外に引き出されて、ソケット1外で主索3の挿通部側と引き出された主索3先端側とが周知のロープクリップ8によって相互に締結される。   Further, the main rope 3 inserted through the tapered space 2 of the socket 1 from the small diameter side is bent in the tapered space 2 through the wedge pieces 6 facing each other. The leading end of the main rope 3 is pulled out of the socket 1 from the main rope lead-out hole 5 and the main rope 3 is pulled out of the socket 1 by the well-known rope clip 8. Is done.

上記のように構成されたエレベーター主索の引き止め具において、互いに対向し係合部7を相互に噛み合わせて係合した楔片6がソケット1のテーパー状空所2内に挿入される。次いで、主索3がソケット1のテーパー状空所2に小径側から挿通され、互いに対向した楔片6の相互間を経てテーパー状空所2内で屈曲され、その先端が主索引き出し孔5からソケット1外に引き出される。   In the elevator main rope retainer configured as described above, the wedge pieces 6 that are opposed to each other and engaged with each other by engaging the engaging portions 7 are inserted into the tapered space 2 of the socket 1. Next, the main rope 3 is inserted into the tapered cavity 2 of the socket 1 from the small diameter side, is bent between the wedge pieces 6 facing each other, and is bent in the tapered cavity 2, and the tip thereof is the main rope extraction hole 5.
