ベータ用給油装置に関する。Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a lubricating device for an elevator that supplies lubricating oil to a guide rail on which an elevating body moves up and down. The present invention relates to an elevator refueling system that can be monitored.
従来のエレベータ用給油装置は、昇降路内に配設された
ガイドレールに案内されて昇降する昇降体(かご)に取

ってかごのガイドシューとガイドレールとの摺動を円滑
にするものである。Conventional elevator lubricating devices are attached to an elevating body (car) that moves up and down guided by guide rails installed in the hoistway, and supply lubricating oil to the guide rails to cool the car's guide shoes and guide rails. This is to ensure smooth sliding between the parts and the parts.
而して、従来のエレベータ用給油装置は、潤滑油を貯留

ことによって潤滑油を円滑に供給し得るようにしていた
。In conventional elevator lubrication systems, when the amount of lubricant in the oil tank decreases due to lubricant consumption, the liquid level becomes low and lubrication by the brush tends to be insufficient, which in turn causes damage to the car's guide shoes and guide rails. The frictional force increases, making the car ride uncomfortable and accelerating the wear of the guide shoes and guide rails. For this reason, during periodic inspections of elevators, lubricating oil is supplied to the oil tank up to a standard level to ensure smooth supply of lubricating oil.
