Automatic detection oil cup and liquid level automatic detection method

Abstract

The invention discloses an automatic detection oil cup and a liquid level automatic detection method to which the automatic detection oil cup is applied. The automatic detection oil cup specifically comprises an oil storage tank body, a cover body, an oil guide device and an oil-wool separator. A liquid level sensor is arranged on the cover body. According to the technical scheme, the position ofthe liquid level in the oil cup can be detected in real time, an alarm signal can be sent when the liquid level is lower than a safety position, maintenance personnel are reminded to fill the oil cupwith lubricating oil in time, thus, the purpose of grasping the oil mass in the oil cup in real time in a non-elevator-stop overhaul state is achieved, the workload of the maintenance personnel and the elevator stop cost of users are reduced, and meanwhile the working safety coefficient of the maintenance personnel is increased.

Description

technical field [0001] The invention relates to the field of elevator accessories, in particular to an automatic detection method for an oil cup and a liquid level. Background technique [0002] At present, in the field of elevators, oil cups are generally installed on the guide shoes, and the lubricating oil in the oil cups is evenly applied to the elevator guide rails through cotton threads, so as to ensure that there is a continuous gap between the elevator guide shoes and the guide rails during the operation of the elevator. The lubricating layer reduces the wear of guide shoes and guide rails and improves the service life of elevator components. [0003] However, most of the current common oil cups do not have an automatic liquid level detection device, and only rely on the scale line in the oil storage cup to judge the oil volume during the refueling process. Moreover, during the operation of the elevator, the real-time amount of oil in the oil cup is not clear. It is...

Problems solved by technology

[0003] However, most of the current ordinary oil cups do not have an automatic liquid level detection device, and only rely on the scale line in the oil storage cup to judge the oil volume during the refueling process.

Moreover, during the operation of the elevator, the real-time amount of oil in the oil cup is not clear. It is necessary to enter the elevator shaft during the regular maintenance of the elevator. The oil guide device in the cup is too long, which leads to the deviation of oil quantity judgment or even false alarm.

In these cases, once the maintenance is not in place, that is, when the oil volume in the oil cup is omitted or the lubricating oil is not carried with you during maintenance, there will be too little remaining oil in the oil cup or the situation of the lubricating oil being exhausted. This has a great impact on the comfort of the elevator during normal operation and the service life of the elevator guide shoes and guide rails

It is easy to cause unnecessary maintenance costs to rise, and even cause safety accidents
