Description

本発明は、トラクションシーブを使用せずにエレベータかご等を往復駆動するためのものにおいて、駆動装置の動作確認方法に関するものである。   The present invention relates to a method for confirming the operation of a drive device for reciprocating an elevator car or the like without using a traction sheave.

図２は、出願人が提案している方式の駆動機構を備えた駆動装置であり（特許文献１参照）、図示省略しているが、主ロープ３の一側にはエレベータかご、他側にはカウンターウェイトが設けられている。駆動装置４０はフレーム４１にシーブ４２を取り付けるとともに、該シーブ４２の上方と両側の３箇所にプーリ４３，４４，４５を配置し、これらのプーリ４３，４４，４５にベルト４６を張設し、このベルト４６によってシーブ４２に巻き付けられた主ロープ３をシーブ４２に押圧する。上方のプーリ４３はフレーム４１の背面に取り付けられたモータ（図示省略）に連結されており、ベルト４６の周回移動により、シーブ４２と主ロープ３を移動させてかごを昇降させる構成になっている。また両側のプーリ４４，４５はそれぞれ位置調節機構４７によって、フレーム４１に対して高さ位置の調節が可能取り付けられており、これら高さ位置を調節することによってベルト４６の張力を調節することができる。４８は非常時等に主ロープ３を挟持するロープグリッパーで油圧等によって動作する。４９はモータの回動状態を検出する検出装置、例えばロータリーエンコーダ、５０はモータのブレーキである。   FIG. 2 shows a drive device having a drive mechanism of the method proposed by the applicant (see Patent Document 1), which is omitted in the figure, but one side of the main rope 3 is on the elevator car and the other side is on the other side. Has a counterweight. The drive device 40 attaches a sheave 42 to a frame 41, and arranges pulleys 43, 44, 45 at three locations above and on both sides of the sheave 42, and stretches a belt 46 around these pulleys 43, 44, 45, The main rope 3 wound around the sheave 42 is pressed against the sheave 42 by the belt 46. The upper pulley 43 is connected to a motor (not shown) attached to the back surface of the frame 41, and is configured to move the sheave 42 and the main rope 3 to move the car up and down by the circular movement of the belt 46. . The pulleys 44 and 45 on both sides are attached to the frame 41 by a position adjusting mechanism 47 so that the height position can be adjusted. By adjusting these height positions, the tension of the belt 46 can be adjusted. it can. Reference numeral 48 denotes a rope gripper that holds the main rope 3 in an emergency or the like, and operates by hydraulic pressure or the like. Reference numeral 49 is a detection device that detects the rotational state of the motor, for example, a rotary encoder, and 50 is a brake for the motor.

前記装置を据え付けるとき、ベルト４６の走行状態を確認し、必要に応じて調整する必要がある。しかし駆動装置４０がエレベータ昇降路内に設置される現場では、足場の設置が困難なため、現場でベルト４６の走行を目視確認するのは非常に難しい。
また、予め工場でベルト４６の走行状態を確認しようとしても、シーブ４２に主ロープ３が掛かっていないため十分な確認ができない。更に図２のように工場内で主ロープ３を掛けることも可能であるが、設備が大掛かりになってしまうという問題があった。 When installing the device, it is necessary to check the running state of the belt 46 and adjust as necessary. However, since it is difficult to install a scaffold at a site where the drive device 40 is installed in the elevator hoistway, it is very difficult to visually check the running of the belt 46 at the site.
Further, even if it is attempted to check the running state of the belt 46 in advance at the factory, the main rope 3 is not hung on the sheave 42, so that sufficient confirmation cannot be made. Further, as shown in FIG. 2, it is possible to hang the main rope 3 in the factory, but there is a problem that the facility becomes large.

そこで、最近出願人は特願２００２−２４９４９０号に記載した方法を提案した。これは主ロープ３の代わりにロープ治具をシーブ４２に取り付けることにより、工場でも容易にベルト４６の走行状態が確認できるようにしたものである。図３に示すように、ロープ治具１０は一対の半環状体１１，１２の一側をピン１３で連結し、他側をばね１４で連結したものである。半環状体１１，１２は主ロープ３と同一の太さであり、ばね１４を広げてシーブ４２の溝に取り付ける構成である。これにより、工場内においても、シーブ４２に主ロープ３が掛かったのと同様の状態でベルト４６を走行させ、その走行状態の確認や調整を行うことができる。
国際公開第０２／０６４４８２号パンフレット Therefore, the applicant recently proposed the method described in Japanese Patent Application No. 2002-249490. By attaching a rope jig to the sheave 42 instead of the main rope 3, the running state of the belt 46 can be easily confirmed even in a factory. As shown in FIG. 3, the rope jig 10 is formed by connecting one side of a pair of semi-annular bodies 11 and 12 with a pin 13 and connecting the other side with a spring 14. The semi-annular bodies 11 and 12 have the same thickness as that of the main rope 3, and are configured to spread the spring 14 and attach it to the groove of the sheave 42. Thereby, also in the factory, the belt 46 can be traveled in the same state as the main rope 3 is hooked on the sheave 42, and the travel state can be confirmed and adjusted.
International Publication No. 02/064482 Pamphlet

前記従来技術では、シーブ４２にロープ治具１０を取り付けて、更にベルト４６を掛けるため手間が掛かるとともに、ロープ治具１０は半環状体１１，１２、ピン１３、ばね１４からなり不均一なため、シーブ４２の溝に主ロープ３が掛かった状態とは若干相違するという問題がある。   In the above prior art, it takes time to attach the rope jig 10 to the sheave 42 and further hang the belt 46, and the rope jig 10 is composed of semi-annular bodies 11, 12, pins 13, and springs 14, and is not uniform. There is a problem that the main rope 3 is slightly different from the state in which the groove of the sheave 42 is hung.

本発明は、主ロープと、主ロープが巻き付く溝を有するシーブと、周回移動するベルトを有し主ロープのシーブに巻き付く部分をベルトで押圧して主ロープをその長手方向に駆動するベルト伝動機構を備えた駆動装置において、駆動装置の動作確認時には、ベルトと主ロープに代えて、ベルトのシーブ側に主ロープに似せた突起が付いた形状のベルトを取り付けた状態で、駆動装置を駆動させるものである。   The present invention relates to a main rope, a sheave having a groove around which the main rope is wound, and a belt that has a belt that circulates and drives the main rope in the longitudinal direction by pressing the portion that winds around the sheave of the main rope with the belt. In a drive unit equipped with a transmission mechanism, when confirming the operation of the drive unit, instead of the belt and the main rope, the drive unit is attached with a belt having a shape similar to the main rope attached to the sheave side of the belt. It is to be driven.

本発明によれば、ベルト伝動機構によりシーブに巻き付けられた主ロープを駆動する駆動装置における、ベルトの走行状態の確認が、工場で容易に行うことができる。   According to the present invention, it is possible to easily check the running state of the belt in the drive device that drives the main rope wound around the sheave by the belt transmission mechanism.

本発明の実施の形態を図１により説明する。工場内においてベルトの走行状態の確認や調整を行うときには、通常のベルト４６に代えて、シーブ４２側に主ロープ３に似せた形の突起２１がシーブ４２の溝４２ａの数だけ設けられたベルト２０を使用する。すなわち、ベルト４６と主ロープ３が一体になったような形状になったベルトを使用する。
これにより、ロープ治具１０を使用することなく、駆動装置４０におけるベルトの走行状態の確認が、工場で容易に行うことができる。
本実施形態によればベルト２０の全長にわたって突起２１が設けられているため、従来のロープ治具１０にくらべ安定した動作ができる。 An embodiment of the present invention will be described with reference to FIG. When checking and adjusting the running state of the belt in the factory, instead of the normal belt 46, a belt having protrusions 21 shaped like the main rope 3 on the sheave 42 side is provided in the number of grooves 42a of the sheave 42. 20 is used. That is, a belt having a shape in which the belt 46 and the main rope 3 are integrated is used.
Thereby, confirmation of the running state of the belt in the drive device 40 can be easily performed at the factory without using the rope jig 10.
According to the present embodiment, since the protrusion 21 is provided over the entire length of the belt 20, a stable operation can be performed as compared with the conventional rope jig 10.
