According to technical scheme recited above, the utlity model has following beneficial effect:
1) the utility model is through gathering the strain value of cylinder side plate, through being converted into stress value, and then is converted into the tension force of steel rope through the moment of torsion formula, judges then whether mining elevator is in the slack rope state.Its device is 1 slack rope monitoring node, is installed on the cylinder side plate, because device adopts the transmission over radio alerting signal, thereby can not exert an influence to the safety of elevator system itself etc.
2) a kind of mining elevator slack rope prior-warning device of relating to of the utility model need not that existing lifting means is done too much change and can realize the slack rope monitoring, alarming, and easy to install and use, maintenance cost is low.
3) a kind of mining elevator slack rope prior-warning device of relating to of the utility model adopts sensor acquisition and transmission over radio, has advantages such as simple in structure, that stability is strong, safe and reliable, operation and maintenance is convenient.
