Abstract

The invention discloses a dynamic radial deformation and dynamic tension monitoring device of a deep-well double-broken-line-type multi-layer winding elevator steel wire rope. The device comprises a pedestal, a driving system, a tension-compression detection system and a dynamic deformation monitoring system. The driving system comprises an electromotor. The electromotor is connected to a roller through a shaft coupling A, a speed reducer and a shaft coupling B. An outer side of a roller baffle plate is tightly contacted with a brake disc. The tension-compression detection system comprises a servo electric cylinder. A S-type tension sensor is connected to the servo electric cylinder and a steel wire rope clamp respectively. A roller surface is provided with a friction liner. A steel wire rope winds a double-broken-line rope groove of a friction liner surface. One end of the steel wire rope clamp is locked through the steel wire rope clamp. A back side of the friction liner is axially provided with a plurality of sensor installation grooves along the roller. A weighing-type pressure sensor is arranged in one sensor installation groove. The dynamic deformation monitoring system comprises a two-dimensional laser sensor. In the invention, tension characteristics of a steel wire rope under various kinds of work conditions can be simulated and a deformation quantity and a tension force of each layer of the steel wire rope can be accurately detected.
