When the operation of the elevator is completed in accordance with a predetermined operation command, the injection operation of the oil spray nozzle is automatically stopped on receiving an oil spray finishing command from the computation part of the elevator control panel, and the oil spray nozzle is restored into an original distant position. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an elevator rust preventive oil automatic application apparatus and method for automatically applying rust preventive oil to an elevator rope that operates in a dry hoistway environment, such as an elevator for observation in which direct sunlight hits an elevator hoistway. It is about.

  When an elevator rope that operates in a dry hoistway environment, such as an elevator for observation in which the elevator hoistway is exposed to direct sunlight, is being inspected, the occurrence of rust is particularly noticeable. If rust is found, rust has already progressed deep into the trough of the strand. Even if rust preventive oil is applied with oil spray, rust is not completely removed, and the elevator rope is replaced with a new one. There is a need. This replacement cycle is uneconomical at around 3-4 years. Moreover, it took time and effort to apply the oil spray.

  As a conventional technique, a rust preventive oil supply device for an elevator rope and a rust preventive oil coating device for an elevator rope are known (for example, see Patent Documents 1 and 2).
