Apparatus and method for automatically adjusting the tension of a flexible guide rail

A method of automatically adjusting a tension of a steel rope that comprises a guide system along which a mining elevator car moves vertically, the method comprising monitoring the tension of the steel rope in real time using an oil pressure sensor, collecting tension data and transferring the collected data to an industrial personal computer of a tension detection system via a signal collector to perform analysis and processing;

• wherein when the tension of the steel rope is lower than a lower limit value set by the industrial personal computer, the industrial personal computer sends a signal to drive a hydraulic system to pressurize a pipeline at a bottom of tightening oil cylinder blocks and push plungers, and the plungers push upwards a tightening fixing rope clamp fixed on a hinge pin fixing seat to tighten the steel rope;
• wherein when a primary lift of the plungers is unable to make the tension of the steel rope reach an upper limit value set by the industrial personal computer, the plungers lift the tightening fixing rope clamp fixed on the hinge pin fixing seat, and a wedge of the tightening fixing rope clamp is disengaged from the steel rope, while due to a self-locking feature of wedges of a rope adjusting guiding clamp and an anti-fall rope clamp, the steel rope is clamped by a wedge of the rope adjusting guiding clamp and the tension of the steel rope is maintained;
• afterwards, the pipeline at the bottom of the tightening oil cylinder blocks is further pressurized to push the plungers upwards, and the monitoring, analysis and processing is repeated until the tension of the steel rope reaches an upper limit value set by the industrial personal computer.
