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.

Description

technical field [0001] The patent of the invention relates to a dynamic monitoring device and method for the radial deformation and tension of the steel wire rope of a deep well double-broken type multi-layer winding hoist, which can simulate various operations of the wire rope in the winding hoist system such as acceleration, deceleration, constant speed, and emergency stop. The characteristics of the tensile force under the condition can be used to explore the real-time radial deformation of each layer of steel wire rope on the drum, the pressure on different areas of the outer wall of the drum, and the dynamic changes of the tension of the steel wire rope. Background technique [0002] The whole process of mine production is inseparable from mine transportation and lifting work. Therefore, the quality of transportation and lifting work is directly related to whether mine production can be carried out normally and efficiently. Mine hoisting equipment is the throat of mine ...
