Abstract:
A system and a method for automatically regulating the tensions of the guide ropes of a flexible cable suspension platform. The system includes a guide rope regulator mounted on a flexible cable suspension platform, a hydraulic pump station arranged on the flexible cable suspension platform, and a hydraulic system associated to the hydraulic pump station. The guide rope regulator automatically regulates the tensions of the guide ropes to enable the tensions of all the guide ropes to be consistent, so as to further ensure that the flexible cable suspension platform is in a level condition. The guide rope regulator also can measure the tension states of the guide ropes conveniently so as to ensure that the guide ropes have enough tensions to efficiently limit the swing amplitude of a lilting container. The system is simple, and convenient to operate, and has a good automatic regulating effect.
Abstract:
A guide rail rope deflection inhibition mechanism and method for a parallel soft cable suspension system in ultradeep vertical shaft construction. The guide rail rope deflection inhibition mechanism comprises a T-shaped installation support base, a rotating frame, a hydraulic support rod, and a chuck. The T-shaped installation support base comprises a vertical support rod and a horizontal support rod. The hydraulic support rod comprises an upper hydraulic support rod and a lower hydraulic support rod. The rotating frame comprises an upper Y-shaped frame and a lower Y-shaped frame. The chuck comprises an upper chuck and a lower chuck. The guide rail rope deflection inhibition method treats two guide rail rope deflection inhibition mechanisms as one group, and arranges at least two groups along the vertical direction on the shaft wall. While guaranteeing the smooth sliding of a direction guiding frame, the freedom of the guide rail rope part is restrained by the chuck, thereby enhancing the stability and safety of hoisting containers.

Abstract:
The present invention discloses a device and method for adjusting tension of a steel wire rope of an ultra-deep vertical shaft at a hoisting-container-end. The device includes two stages of steel wire rope tension adjusting devices provided on a hoisting container, where a primary steel wire rope tension adjusting device includes left and right steel wire rope tension adjusting devices that are symmetrically arranged, and a secondary steel wire rope tension adjusting device is provided below the primary steel wire rope tension adjusting device. By use of two stages of steel wire rope tension adjusting devices, tension on four steel wire ropes can be adjusted to equalize the tension, thus meeting the requirement for tension equalization in a hoisting process. The four steel wire ropes are equally divided into two groups. Tension of two steel wire ropes is adjusted by rotating a primary drum around which the two steel wire ropes are wound, and then tension of the four steel wire ropes is adjusted by rotating a secondary drum around which the multiple steel wire ropes are wound, thus achieving a final purpose. The device of the present invention has a simple structure, and is conveniently mounted and easily detached. The tension is automatically adjusted by rotating the drums. This solution is novel and has wide application.
