DEVICE AND METHOD FOR TESTING ANTI-SLIP PERFORMANCE OF FRICTION LINER FOR MINE HOISTING

摘要

Disclosed is a device for testing the anti-slip performance of a friction liner for mine hoisting, the device comprising a positioning platform (6), a tension loading device (1), two tension positioning devices (2), a steel wire rope limiting device (3), a steel wire rope dragging device (5), two radian positioning devices (7) and a liner loading device (8), wherein all sub-devices are arranged on the positioning platform (6) in a circumferential direction, and the two radian positioning devices (7) are symmetrically arranged on two sides of the liner loading device (8) at equal included angles. The positive pressure and friction borne by a friction liner (9) are simulated based on loading by means of a hydraulic cylinder (1-a) and dragging with an endless steel wire rope (4), the radian of a winding drum is simulated by using the two radian positioning devices (7) arranged at equal included angles, and the friction and wear form of the friction liner (9) is tested at different steel wire rope transmission speeds, different positive pressures and different friction distances by means of dragging with the endless steel wire rope (4), so that the friction coefficient of the friction liner (9) can be tested, and the high-speed sliding friction working condition of the liner can be effectively simulated, thereby testing friction liners (9) with different radians and diameters of rope race so as to accurately evaluate the anti-slip performance of the friction liners (9).
