A wound lifting wire rope impact friction test system in a kilometer-deep well, comprising: a frame (5), a roller (1) is disposed on the left end of the frame (5), and is mounted within a bearing block (8) above the frame (5) via a roller central shaft (9), the roller central shaft (9) is connected to a variable-speed motor (6) via a torque and rotational speed meter (7), a thrust oil cylinder (4) is horizontally disposed at the same height as the roller central shaft (9) on the right end of the frame (5), the thrust oil cylinder (4) and a friction wheel (2) are connected together via a pin, a centroid position of the friction wheel (2) is located at the same height as the thrust oil cylinder (4), two sides of the friction wheel (2) are fixed on a movable bearing (3), the movable bearing (3) is mounted on a guide rail (13) fixed on the frame, two wire ropes (10) are wound side by side on the roller (1), and one wire rope (12) is wound on the friction wheel (2). The system simulates a working condition of wound lifting wire rope impact friction test system in a kilometer-deep well, studies tribology property of the wire rope under different rotational speeds, accelerations, impact velocities, and contact pressures, and has a simple and compact structure, a low cost, and provides an easy method and effective results.
Description
technical field [0001] The invention relates to an impact friction test system for winding and hoisting steel wire ropes in a thousand-meter deep well, which can conduct friction research on the impact friction fatigue behavior between hoisting wire ropes, and specifically relates to a winding hoist driving wheel torque speed, which can be measured Test system for friction temperature rise and friction coefficient between steel wire ropes. Background technique [0002] With the continuous development of mine hoisting depth in our country, the design, production and use of deep shaft hoists have become the mainstream direction of hoist development in our country. For a thousand-meter deep well hoist, wire rope failure is a key factor restricting its life. Among them, during the winding hoisting process in a thousand-meter deep well, the hoisting speed can reach 25m / s, and the high-speed impact and extrusion friction and wear between the wire ropes and between different layer...
