Abstract
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.
