摘要:
A tension balance system for steel wire ropes on a friction hoisting driving end of an ultra-deep well includes a friction wheel, left and right guiding wheels, left and right steel wire ropes, left and right adjustment wheels, left and right rewinding wheels, left and right adjustment oil cylinders, a hydraulic pipeline, a pump station, a pipeline switch group, left and right hoisting containers, balance ropes, and reels. The friction wheel is disposed in the middle, the left and right adjustment wheels and the left and right rewinding wheels are circularly distributed around the friction wheel, the left and right guiding wheels, the left and right adjustment wheels, and left and right rewinding wheels are all symmetrically disposed on two sides of the friction wheel; both a quantity of left steel wire ropes and a quantity of right steel wire ropes are even numbers more than 2.
