Description

本発明は、サイズの異なるガイドレール部材を連結することが可能なガイドレールの継目板を備えたエレベータ装置に関するものである。   The present invention relates to an elevator apparatus including a guide rail joint plate capable of connecting guide rail members of different sizes.

一般的に、エレベータのかご及び釣り合いおもりを円滑に走行させるために昇降路のほぼ全長に渡ってガイドレールが設置されている。しかしながら、長尺のガイドレールを一体で構成することは事実上不可能であるため、サイズが同じ複数のガイドレール部材を継目板で連結して昇降路内に設置しなければならなかった。このため、例えばマシンルームレスエレベータにおいて、カーヒッチ等をガイドレールに固定すると、一部のガイドレールにのみ大きな曲げモーメントが作用するので、該曲げモーメントに対応したサイズの大きなガイドレール部材を全長に渡って使用する必要があった。
特許第2513802号公報 特開2001−171943号公報
Generally, guide rails are installed over almost the entire length of the hoistway in order to smoothly run the elevator car and the counterweight. However, since it is practically impossible to integrally form a long guide rail, a plurality of guide rail members having the same size must be connected by a joint plate and installed in the hoistway. For this reason, for example, in a machine roomless elevator, when a car hitch or the like is fixed to a guide rail, a large bending moment acts only on some of the guide rails. Therefore, a large guide rail member corresponding to the bending moment is extended over the entire length. Needed to be used.
Japanese Patent No. 2513802 JP 2001-171943 A

しかし、上記のように一部のガイドレール部材にのみ大きな曲げモーメントが作用するために、全てのガイドレール部材のサイズを大きくしてしまうとガイドレール部材の重量が増加するだけではなく、その他の支持部材のサイズも大きくなり、据付作業性の低下やコストが増加するという問題があった。 However, since a large bending moment acts only on some of the guide rail members as described above, increasing the size of all the guide rail members will not only increase the weight of the guide rail members, but also There was a problem that the size of the support member also increased, resulting in a decrease in installation workability and an increase in cost.

本発明は、上記事情に鑑みてなされたもので、曲げモーメントの大きさに応じたサイズの異なるガイドレール部材を接続して、ガイドレール部材の重量の増加及びコストの増加を抑えることにある。 This invention is made | formed in view of the said situation, and connects the guide rail member from which the size differs according to the magnitude | size of a bending moment, and exists in suppressing the increase in the weight of a guide rail member, and the increase in cost.

本発明は、サイズの異なるガイドレール部材を含む複数のガイドレール部材からなるエレベータのガイドレールと前記ガイドレール部材の一端と該ガイドレール部材とはサイズの異なるガイドレール部材の一端を連結する継目板を備え、前記継目板はサイズの大きなガイドレール部材とサイズの小さなガイドレール部材の表面(歯面)を揃えたときに生じる段差に対応する段差を設けると共に、サイズの大きなガイドレール部材とサイズの小さなガイドレール部材の連結部の両端からサイズの小さなガイドレール部材に向かって突出部を斜めに切欠いた形状を有することを特徴とする。 The present invention relates to an elevator guide rail comprising a plurality of guide rail members including guide rail members of different sizes, one end of the guide rail members, and a joint plate for connecting one end of the guide rail members of different sizes. The joint plate is provided with a step corresponding to a step generated when the surface (tooth surface) of the large guide rail member and the small guide rail member are aligned, and the large guide rail member and the size A projecting portion is obliquely cut from both ends of the connecting portion of the small guide rail member toward the small guide rail member .

本発明によれば、サイズの異なるガイドレール部材を連結することが出来るので、上から下までサイズの同じガイドレール部材を使用する必要はなく、曲げモーメントの大きさに応じたガイドレール部材を使用することが出来る(大きな曲げモーメントがかかる部分にはサイズの大きなガイドレール部材を使用する)ので、コストの削減と重量の減少により据付作業性についても向上する。また、継目板の形状を斜めに切欠くようにしたからロープが継目板に引っ掛かる恐れもない。 According to the present invention, since guide rail members of different sizes can be connected, there is no need to use guide rail members of the same size from top to bottom, and guide rail members according to the magnitude of the bending moment are used. (A guide rail member having a large size is used in a portion where a large bending moment is applied), so that installation workability is improved by reducing cost and weight. Further, since the shape of the joint plate is cut obliquely, there is no fear that the rope will be caught on the joint plate.

以下、本発明の実施例について図面を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings.

図1は本発明の実施の形態におけるガイドレール装置の継目板の側面図であり、1はサイズの大きなガイドレール部材、2はサイズの小さなガイドレール部材、3はガイドレールの継目板、4はボルト、5はナットである。 FIG. 1 is a side view of a joint plate of a guide rail device according to an embodiment of the present invention. 1 is a large guide rail member, 2 is a small guide rail member, 3 is a guide rail joint plate, Bolts 5 are nuts.

実施の形態によると、サイズの大きなガイドレール部材1の表面(歯面)とサイズの小さなガイドレール部材2の表面(歯面)を揃えると、ガイドレール部材1とガイドレール部材2の高さが異なるため裏面に段差が出来る。この段差と対応する段差を設けたガイドレールの継目板3を、ガイドレール部材1とガイドレール部材2の裏面に配置してボルト4とナット5で前記ガイドレール部材1及び前記ガイドレール部材2を連結する。 According to the embodiment, when the surface (tooth surface) of the large guide rail member 1 and the surface (tooth surface) of the small guide rail member 2 are aligned, the height of the guide rail member 1 and the guide rail member 2 is increased. Because it is different, there is a step on the back. A guide rail joint plate 3 provided with a step corresponding to the step is disposed on the back surfaces of the guide rail member 1 and the guide rail member 2, and the guide rail member 1 and the guide rail member 2 are connected by bolts 4 and nuts 5. Link.

図2は本発明の実施の形態におけるガイドレール装置の継目板3の正面図であり、サイズの大きなガイドレール部材1の連結部の両端からサイズの小さなガイドレール部材2に向かって斜めに切欠いてる。また、ガイドレール部材1及びガイドレール部材2のサイズに応じて締結用の穴が空けられている。
以上により、本発明によれば、サイズの異なるガイドレール部材を連結することが出来るので、曲げモーメントの大きさに応じたガイドレール部材を使用することが出来る。また、ロープ等が継目板に引っ掛かることによる重大事故を未然に防止することも出来る。
FIG. 2 is a front view of the joint plate 3 of the guide rail device according to the embodiment of the present invention, and is obliquely cut from both ends of the connecting portion of the large guide rail member 1 toward the small guide rail member 2. . Further, fastening holes are formed according to the sizes of the guide rail member 1 and the guide rail member 2.
As described above, according to the present invention, since guide rail members having different sizes can be connected, the guide rail member according to the magnitude of the bending moment can be used. Further, it is possible to prevent a serious accident caused by a rope or the like being caught on the joint plate.

その他、本発明は上記の実施例に限定されるものではなく、本発明の要旨を逸脱しない範囲で、種々の改変を施すことができる。 In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.
