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

摘要

Disclosed are an apparatus and 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 apparatus and the method allow the flexible guide rail to be structurally simple, convenient to process, reliable in performance, and easy to install and to maintain. The apparatus and the method allow restriction of vertical orientation and horizontal deflection, and are capable of real-time detection and automatic adjustment of the tension in the flexible guide rail of the elevator.
