以下、本発明に係る制動装置の異常検出装置の点検補助装置、及び点検補助方法の実施の形態を図面に基づいて説明する。   DESCRIPTION OF EMBODIMENTS Embodiments of an inspection auxiliary device and an inspection auxiliary method for an abnormality detection device for a braking device according to the present invention will be described below with reference to the drawings.

はじめに、本発明に係る異常検出装置の点検補助装置の一実施形態が取り付けられるエレベータの巻上機に備えられる制動装置の全体構成、及びこの制動装置において生じる異常状態について、図1,2に基づいて説明する。   First, based on FIGS. 1 and 2, an overall configuration of a braking device provided in an elevator hoisting machine to which an embodiment of an inspection auxiliary device for an abnormality detecting device according to the present invention is attached and an abnormal state occurring in the braking device will be described. I will explain.

図1に示すように、主レバー5A,5Bの上部には、ロッド2をマグネットケース1を貫通するように取り付けてある。制動状態にあっては、ロッド2と、このロッド2に装着された圧縮ばね3とによって、主レバー5Aと主レバー5Bは、その上方部分が互いに近づく方向に狭められる。これにより、主レバー5A,5Bのそれぞれに取り付けられたブレーキシュ6A,6Bに一体に設けられたライニング7A,7Bは、回転ドラム8に押し付けられ、制動力が発生する。この制動力の調整は、圧縮ばね3の締め付け距離を調整することにより行われる。   As shown in FIG. 1, the rod 2 is attached to the upper part of the main levers 5 </ b> A and 5 </ b> B so as to penetrate the magnet case 1. In the braking state, the main lever 5A and the main lever 5B are narrowed by the rod 2 and the compression spring 3 attached to the rod 2 so that the upper portions thereof approach each other. As a result, the linings 7A and 7B provided integrally with the brake shoes 6A and 6B attached to the main levers 5A and 5B are pressed against the rotary drum 8 to generate a braking force. The adjustment of the braking force is performed by adjusting the tightening distance of the compression spring 3.

図2に示すように、マグネットケース1内には、プランジャ10A,10Bが互いに対向するように配置されている。プランジャ10Aには、プランジャ10Bに貫入するロッド12Aとロッド12Bが取り付けられ、これらのロッド12A,12Bの端部にはプレート13が取り付けられている。このプレート13は、ボルト4Bによって押されている。   As shown in FIG. 2, plungers 10 </ b> A and 10 </ b> B are arranged in the magnet case 1 so as to face each other. A rod 12A and a rod 12B penetrating the plunger 10B are attached to the plunger 10A, and a plate 13 is attached to the ends of these rods 12A and 12B. This plate 13 is pushed by a bolt 4B.

プランジャ10Bには、プランジャ10Aに貫入するロッド11が取り付けられ、このロッド11はボルト4Aによって押されている。ボルト4Bは、主レバー5Bに締結され、ボルト4Aは、主レバー5Aに締結されている。   A rod 11 penetrating the plunger 10A is attached to the plunger 10B, and this rod 11 is pushed by a bolt 4A. The bolt 4B is fastened to the main lever 5B, and the bolt 4A is fastened to the main lever 5A.

マグネットケース1内は、このように構成してあることから、電磁コイル9に所定以上の電流が通電されると、プランジャ10Aはプランジャ10B側に引き寄せられ、ロッド12A,12B、及びプレート13を介してボルト4Bが押圧される。これにより主レバー5B、この主レバー5Bに取り付けられたブレーキシュ6B、及びブレーキシュ6Bに取り付けられたライニング7Bが回転ドラム8から離れる。   Since the inside of the magnet case 1 is configured in this way, when a predetermined current or more is applied to the electromagnetic coil 9, the plunger 10A is drawn toward the plunger 10B, and the rods 12A and 12B and the plate 13 are interposed. Then, the bolt 4B is pressed. As a result, the main lever 5B, the brake shoe 6B attached to the main lever 5B, and the lining 7B attached to the brake shoe 6B are separated from the rotary drum 8.

同様に、前述のように電磁コイル9に所定値以上の電流が通電されると、プランジャ10Bもプランジャ10A側に引き寄せられ、ロッド11を介してボルト4Aが押圧される。これにより、主レバー5A、この主レバー5Aに取り付けられたブレーキシュ6A、及びブレーキシュ6Aに取り付けられたライニング7Aが回転ドラム8から離れる。   Similarly, when a current of a predetermined value or more is applied to the electromagnetic coil 9 as described above, the plunger 10B is also drawn toward the plunger 10A and the bolt 4A is pressed via the rod 11. As a result, the main lever 5A, the brake shoe 6A attached to the main lever 5A, and the lining 7A attached to the brake shoe 6A are separated from the rotary drum 8.

これらにより、回転ドラム8に対する制動が解除された状態となる。したがって、図示しない主ロープの移動が可能になり、図示しない昇降路内に配置された乗かご及びつり合い重りの昇降が可能となる。   As a result, braking on the rotating drum 8 is released. Therefore, the main rope (not shown) can be moved, and the elevator car and the counterweight arranged in the hoistway (not shown) can be raised and lowered.

前述した制動解除状態において、電磁コイル9の電流が切れると、プランジャ10Aとプランジャ10Bの引き寄せ合う力が無くなり、ロッド2に装着された圧縮ばね3によって主レバー5Aと主レバー5Bが狭められる。これにより、ブレーキシュ6A,6Bに取り付けられたライニング7A,7Bは、回転ドラム8に押圧され、回転ドラム8が制動された状態となる。したがって、図示しない主ロープは移動不能に保持され、図示しない乗かご、及びつり合い重りは停止状態に保持される。   In the above-described braking release state, when the current of the electromagnetic coil 9 is cut off, the pulling force between the plunger 10A and the plunger 10B disappears, and the main lever 5A and the main lever 5B are narrowed by the compression spring 3 attached to the rod 2. As a result, the linings 7A and 7B attached to the brake shoes 6A and 6B are pressed by the rotating drum 8, and the rotating drum 8 is braked. Accordingly, the main rope (not shown) is held immovable, and the car (not shown) and the counterweight are held in a stopped state.

次に、このような制動装置において生じ得る異常状態について説明する。   Next, an abnormal state that can occur in such a braking device will be described.

プランジャ10Aが固渋すると、電磁コイル9に所定以上の電流が通電されても、プランジャ10Aはプランジャ10B方向へ完全には引き寄せられず、ボルト4Bを押し出すことができなくなる。したがって、主レバー5B、主レバー5Bに取り付けられたブレーキシュ6B、及びこのブレーキシュ6Bに取り付けられたライニング7Bが、回転ドラム8から十分に離れることができない状態となる。   When the plunger 10A is stiff, even if a current greater than a predetermined value is applied to the electromagnetic coil 9, the plunger 10A is not completely drawn in the direction of the plunger 10B, and the bolt 4B cannot be pushed out. Accordingly, the main lever 5B, the brake shoe 6B attached to the main lever 5B, and the lining 7B attached to the brake shoe 6B cannot be sufficiently separated from the rotating drum 8.

この状態で回転ドラム8が回転すると、ライニング7Bと回転ドラム8が擦り合い、摩擦熱が発生して発煙する。プランジャ10Bが固渋した場合も、前述と同様な状況となる。   When the rotating drum 8 rotates in this state, the lining 7B and the rotating drum 8 rub against each other, generating frictional heat and generating smoke. Even when the plunger 10B is stiff, the situation is similar to that described above.

次に、前述した制動装置の異常を検出する異常検出装置を点検する際に用いられる本実施形態に係る点検補助装置、及び点検補助方法について、図3,4に基づいて説明する。   Next, an inspection assistance device and an inspection assistance method according to the present embodiment used when inspecting the abnormality detection device that detects the abnormality of the braking device described above will be described with reference to FIGS.

前述したライニング7Bと回転ドラム8との擦れ合いによって生じる摩擦熱の温度が、所定値を超えたときに異常信号を出力する異常検出装置に含まれる温度センサ14は、例えばブレーキシュ6Bに貫入させて、回転ドラム8と対向する側とは反対側を形成する当該ライニング7Bの裏面に設けてある。   The temperature sensor 14 included in the abnormality detection device that outputs an abnormality signal when the temperature of frictional heat generated by the friction between the lining 7B and the rotating drum 8 exceeds a predetermined value is inserted into the brake shoe 6B, for example. Thus, it is provided on the back surface of the lining 7B that forms the side opposite to the side facing the rotating drum 8.

本実施形態に係る異常検出装置の点検補助装置は、ブレーキシュ6Bの表面部、例えば正面部に取り付けられるヒータ15と、ブレーキシュ6Bの表面部、例えば側面部に取り付けられる温度検出器16とを備えている。ヒータ15は温度センサ14の近傍に配置してあり、温度検出器16は温度センサ14から少し離れた位置に配置してある。すなわち、温度センサ14とヒータ15との距離に比べて、温度検出器16とヒータ15との距離を予め大きく設定してある。   The inspection auxiliary device for an abnormality detection device according to the present embodiment includes a heater 15 attached to the surface portion of the brake shoe 6B, for example, the front portion, and a temperature detector 16 attached to the surface portion of the brake shoe 6B, for example, the side portion. I have. The heater 15 is disposed in the vicinity of the temperature sensor 14, and the temperature detector 16 is disposed at a position slightly away from the temperature sensor 14. That is, the distance between the temperature detector 16 and the heater 15 is set larger in advance than the distance between the temperature sensor 14 and the heater 15.

以上のような本実施形態に係る点検補助装置を用いて行う本実施形態に係る点検補助方法は、以下のとおりである。   The inspection assistance method according to this embodiment performed using the inspection assistance device according to this embodiment as described above is as follows.

最初に、ヒータ15によってブレーキシュ6Bを加熱する。この加熱によるブレーキシュ6Bの温度を温度検出器16で検出する。この温度検出器16で検出される温度が、制動装置の異常時のライニング7Bの上昇温度に相応する所定温度に至ったかどうか確認し、所定温度に至った時に温度センサ14を含む異常検出装置の点検を行うようにする。   First, the brake shoe 6B is heated by the heater 15. A temperature detector 16 detects the temperature of the brake shoe 6B due to this heating. It is confirmed whether or not the temperature detected by the temperature detector 16 has reached a predetermined temperature corresponding to the rising temperature of the lining 7B when the braking device is abnormal, and when the temperature reaches the predetermined temperature, the abnormality detection device including the temperature sensor 14 is detected. Make an inspection.

前述した本実施形態に係る制動装置の異常検出装置の点検補助装置、及び点検補助方法にあっては、温度センサ14と温度検出器16は同じブレーキシュ6Bに取り付けられていることから、熱伝導率は同一である。この場合、ヒータ15からの距離が長い方が温度上昇は遅くなる。したがって、温度センサ14とヒータ15との距離に比べて、温度検出器16とヒータ15との距離を予め大きく設定してあることから、ヒータ15の加熱によって温度検出器16で検出された温度が前述した所定温度に至ったときには、異常検出装置の温度センサ14が制動装置のライニング7Bが異常と見做される温度を検出している状態、すなわち制動装置の異常状態が作り出されている状態となる。この状態の時に異常検出装置の点検作業を実施すればよい。   In the inspection auxiliary device and the inspection auxiliary method for the abnormality detection device for a braking device according to the present embodiment described above, the temperature sensor 14 and the temperature detector 16 are attached to the same brake shoe 6B. The rate is the same. In this case, the temperature rise is slower as the distance from the heater 15 is longer. Therefore, since the distance between the temperature detector 16 and the heater 15 is set larger in advance than the distance between the temperature sensor 14 and the heater 15, the temperature detected by the temperature detector 16 due to the heating of the heater 15 is set. When the predetermined temperature is reached, the temperature sensor 14 of the abnormality detection device detects a temperature at which the lining 7B of the braking device is regarded as abnormal, that is, a state where an abnormal state of the braking device is created. Become. What is necessary is just to inspect the abnormality detection apparatus in this state.

本実施形態によれば、ヒータ15と温度検出装置16を同じブレーキシュ6Bの表面部に取り付けたことから、これらのヒータ15及び温度検出器16の取り付け、取り外しを容易に行うことができ、制動装置の異常状態を再生させることなく、また温度センサ14の取り外しを要することなく、制動装置の異常を検出する異常検出装置の点検作業を行うことができる。これにより本実施形態は、異常検出装置の点検作業が簡単になって短時間で行うことができ、点検作業能率を向上させることができる。   According to the present embodiment, since the heater 15 and the temperature detector 16 are attached to the surface portion of the same brake shoe 6B, the heater 15 and the temperature detector 16 can be easily attached and detached, and braking is performed. The inspection operation of the abnormality detection device for detecting the abnormality of the braking device can be performed without regenerating the abnormal state of the device and without requiring the temperature sensor 14 to be removed. As a result, in the present embodiment, the inspection work of the abnormality detection device can be simplified and performed in a short time, and the inspection work efficiency can be improved.

なお、前述した実施形態にあっては、温度センサ14をライニング7Bの裏面に設け、ヒータ15をブレーキシュ6Bの正面部に設け、温度検出器16をブレーキシュ6Bの側面部に設けたが、温度センサ14をライニング7Aの裏面に設け、ヒータ15をブレーキシュ6Aの正面部に設け、温度検出器16をブレーキシュ6Aの側面部に設けた構成にしてもよい。   In the above-described embodiment, the temperature sensor 14 is provided on the back surface of the lining 7B, the heater 15 is provided on the front surface of the brake shoe 6B, and the temperature detector 16 is provided on the side surface of the brake shoe 6B. The temperature sensor 14 may be provided on the back surface of the lining 7A, the heater 15 may be provided on the front surface of the brake shoe 6A, and the temperature detector 16 may be provided on the side surface of the brake shoe 6A.

また、前述した実施形態にあっては、温度検出器16をブレーキシュ6Bの側面部に取り付けたが、この温度検出器16をブレーキシュ6Bの正面部に取り付けてもよい。温度検出器16をブレーキシュ6Aに設ける場合も同様に、温度検出器16をブレーキシュ6Aの正面部に設けてもよい。   In the above-described embodiment, the temperature detector 16 is attached to the side surface of the brake shoe 6B. However, the temperature detector 16 may be attached to the front portion of the brake shoe 6B. Similarly, when the temperature detector 16 is provided in the brake shoe 6A, the temperature detector 16 may be provided in the front portion of the brake shoe 6A.
