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.

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.

The present invention discloses a device and a method for detecting the tension on a guide rope of a hanging scaffold in a construction shaft. The guide rope is released by a winch, rounds over a hoisting sheave, is connected to the hanging scaffold, and then is tensioned up; the hoisting sheave is disposed at a position above the winch, and the device comprises a slide device, two tension ropes, and a pull rope, wherein, the slide device is fitted around the guide rope, the two tension ropes are fixed to the two sides of the slide device respectively and arranged parallel to the guide rope, the pull rope is fixed to the lower part of the slide device and arranged perpendicular to the guide rope. On the basis of the basic principles of mechanics, the force applied on the guide rope can be calculated indirectly according to the proportional relation between the forces applied on the tension rope and guide rope and the lengths of the ropes. The device disclosed in the present invention is simple, and the method disclosed in the present invention is skillful. The device and method are applicable to thick and thin steel wire ropes and highly universal, and are low in cost.
