Abstract: A tensioning device and a tensioning method for a steel wire rope of a cage guide of an ultra-deep vertical shaft. The tensioning device comprises an upper rope clamping device, a rope adjustment guide frame, a lower hydraulic rope locking device, and a lower hydraulic rope adjustment device. The upper rope clamping device is provided with a rope clamp and a pressure sensor. The rope adjustment guide frame comprises a steel frame body, double fixed clamp-plates, a balance weight, and a balance weight steel wire rope. Double moving clamp-plates are disposed in a guide groove of the steel frame body. The double moving clamp-plates are provided with a rope clamp and a lower guide pulley. The double fixed clamp-plates are provided with an upper guide pulley. The balance weight is provided with a fastening joint. Each of the upper rope clamping device, the lower hydraulic rope locking device and the lower hydraulic rope adjustment device comprises a wedged iron block and a shim. Each of the lower hydraulic rope locking device and the lower hydraulic rope adjustment device further comprises a lever wedge adjustment mechanism and a wedge adjustment hydraulic cylinder. A wedge adjustment hydraulic pressing rod is connected to the wedged iron block. The bodies of the wedge adjustment hydraulic cylinders are connected to the shims. The tensioning device and the tensioning method can be used for implementing automatic adjustment and control of the tensile force of the steel wire rope of the cage guide of the ultra-deep vertical shaft.
