Description

本発明は、作業員がエレベータのかご上に搭乗して保守点検作業を行うために用いられるエレベータのかご上保守作業用治具に関する。   The present invention relates to a jig for maintenance work on an elevator car used for a worker to get on the elevator car and perform maintenance inspection work.

巻上機や制御盤を昇降路内の上部に収めたエレベータの保守作業では、例えば、かご上搭乗時のエレベータの運転を制限する技術がある（例えば、特許文献１参照）。また、同様の保守作業時において、かご上搭乗後に物理的にかごの上昇を防ぐ手段を設置する技術もある（例えば、特許文献２、３参照）。   In the maintenance work of the elevator in which the hoisting machine and the control panel are housed in the upper part of the hoistway, for example, there is a technique for restricting the operation of the elevator when riding on the car (for example, see Patent Document 1). There is also a technique of installing a means for physically preventing the car from rising after boarding the car during the same maintenance work (see, for example, Patent Documents 2 and 3).

しかしながら、従来技術には、以下のような課題がある。
特許文献１は、制御的にかご上搭乗時のエレベータの運転を制限するものであり、物理的にかごの上昇を止めるわけではない。このため、何らかの原因でロープやブレーキが滑った場合には、かごが突き上げられ、作業員がかご上に閉じ込められる可能性がある。一方、特許文献２、３は、物理的にかごの上昇を止めるものである。しかしながら、保守作業員がかご上に搭乗した後に設置するものであるため、搭乗から設置までの間にかごが滑り始めた場合には、かごを止めることができない。 However, the prior art has the following problems.
Patent document 1 controls the operation of the elevator when boarding the car in a controlled manner, and does not physically stop the rise of the car. For this reason, when a rope or a brake slips for some reason, the car is pushed up, and there is a possibility that an operator is trapped on the car. On the other hand, Patent Documents 2 and 3 physically stop the rise of the car. However, since the maintenance worker installs after boarding the car, the car cannot be stopped if the car starts to slip between boarding and installation.

本発明は、かかる問題点を解決するためになされたもので、保守作業員がかご上に搭乗する前に、かごの上昇を機械的に制限することができるエレベータのかご上保守作業用治具を得ることを目的とする。   The present invention has been made to solve such a problem, and a maintenance work jig on an elevator car that can mechanically limit the ascent of the car before a maintenance worker gets on the car. The purpose is to obtain.
