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.

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

A mining elevator traction cable connecting apparatus and a measuring method therefor, for use in a mining elevator serving a deep-mine. The apparatus includes an industrial personal computer (IPC), a signal collector connected to the IPC, multiple symmetrically arranged cable rings for use in connecting to one end of a traction cable, and a traction cable tension adjusting apparatus connected to the multiple of cable rings. Arranged within the traction cable tension adjusting apparatus are a plurality of hydraulic cylinders, and a plurality of draw wire displacement sensors for use in monitoring the relative displacement between each hydraulic cylinder plunger and a corresponding hydraulic cylinder body. The draw wire displacement sensors and an oil pressure sensor connected to a hydraulic pipeline are connected to the IPC via the signal collector, forming a traction cable tension and degree of adjustment measuring system.
