Abstract

The invention discloses a device and method for monitoring the dynamic contact status between a multi-layer winding steel wire rope and a winding drum of an extradeep well. The device comprises a supporting system, a winding system, a dynamic loading monitoring system and a stress monitoring system, wherein the winding system comprises an electromotor; the electromotor is connected with a main shaft through a speed reducer; a flange plate is arranged on the main shaft; a double broken line winding drum that sleeves the main shaft is fixed with the flange plate; a friction disk is fixed on each of the two sides of the double broken line winding drum; a disk brake is fixed on one side of each of the friction disks; the steel wire rope is wound on the rope groove of the double broken line winding drum for at least two layers; the dynamic loading monitoring system comprises a servo electric cylinder; a threaded rod of the servo electric cylinder is connected with a steel wire rope fixture through an S type tension sensor; one end of the steel wire rope penetrates through the steel wire rope fixture to be tightly locked; U-shaped through grooves are formed in each of the rope groove and a baffle of the double broken line winding drum; strain gauges are adhered onto the inner wall of each of the U-shaped through grooves. According to the device and method, the dynamic contact stress, produced by the steel wire rope, acting on the surface of the double broken line winding drum and the baffle of the winding drum can be monitored in real time.

Description

technical field [0001] The invention relates to an ultra-deep well multi-layer winding steel wire rope and drum dynamic contact state monitoring device and method, which is used to study the double-fold line of the ultra-deep well winding hoist double-fold line multi-layer winding steel wire rope and the drum during the lifting process of the steel wire rope under dynamic load. Dynamic contact stresses on the drum surface and double-broken drum baffles. Background technique [0002] As the necessary transportation equipment for mines, mine hoists are responsible for lifting minerals and lifting personnel, equipment and materials during the production process, and are an important hub connecting the ground and underground. In my country, the coal resources under the thousand-meter strata account for 53% of the proven coal reserves. Therefore, the mining and transportation of ultra-deep mines have attracted extensive attention. Two types of shaft multi-rope friction hoisting ...
