Title: TENSION ADJUSTING DEVICE AND METHOD FOR STEEL WIRE ROPES ON HOISTING CONTAINER OF ULTRA-DEEP VERTICAL SHAFT
Abstract:
A tension adjusting device and method for steel wire ropes on a hoisting container of an ultra-deep vertical shaft, the device comprising two stages of steel wire rope tension adjusting devices arranged on a hoisting container (4). The first-stage steel wire rope tension adjusting device (1) comprises left and right steel wire rope tension adjusting devices which are symmetrically arranged, and the second-stage steel wire rope tension adjusting device (3) is arranged below the first-stage steel wire rope tension adjusting device (1). The tensile forces of the four steel wire ropes may be adjusted and balanced by means of the two stages of steel wire rope tension adjusting devices, and the requirement for tension balance in the hoisting process is thus met. The four steel wire ropes are divided in pairs, a first-stage winding drum on which two steel wire ropes are wound is rotated to adjust the tensile forces of the two steel wire ropes, and a second-stage winding drum on which the steel wire ropes are wound is further rotated to adjust the tensile forces of the four steel wire ropes, so as to achieve the final purpose. The tension adjusting device is simple in structure, convenient to mount and easy to disassemble; additionally, the tensile forces are adjusted automatically by rotating the winding drums, and thus the invention has a wide scope of application.
