This invention is a monitoring device for dynamic radial deformation and dynamic tension of wire ropes on double broken line multi-layer winding hoists for deep mines, including base frame, driving system, tension and compression testing system, and dynamic deformation monitoring system. The driving system includes, among others, a motor. The motor is connected with the drum via coupler A, reducer and coupler B. The outer side of the drum baffle attaches to the brake disc. The tension and compression testing system includes a servo electric cylinder, etc. The S-type tension sensor connects the servo electric cylinder and wire rope fixture. The drum surface is fitted with a friction lining, and wire ropes are wound on the double broken line grooves of the friction lining surface. One end of the wire rope fixture is fastened via the wire rope U-shaped lock on the wire rope fixture. The back of the friction lining is fitted with multiple sensor mounting grooves along the axial direction of the drum. The weighing type pressure sensor is mounted in the sensor mounting groove. The dynamic deformation monitoring system includes a 2D laser sensor. The invention can simulate the characteristics of tensile force on wire ropes under multiple operating conditions and accurately test the deformation and tension of each layer of wire ropes.
