Title:
DEVICE FOR TESTING BEARING PERFORMANCE OF VERTICAL SHAFT LIFTING SPINDLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/073578
Kind Code:
A1
Abstract:
A device for testing the bearing performance of a vertical shaft lifting spindle device, comprising a vertical substrate (1), a hydraulic loading device (2), a loading positioning platform (3) and a horizontal base (8). The horizontal base (8) is arranged in a horizontal longitudinal direction; the vertical substrate (1) is horizontally arranged across the center line of the horizontal base (8); the loading positioning platform (3) is arranged on the vertical substrate (1) along an arc-shaped notch; the hydraulic loading device (2) is arranged on the loading positioning platform (3) and the vertical substrate (1) in the circumferential direction. On the basis of a multi-point hydraulic cylinder loading mode, positive pressure applied to the spindle device along the circumferential direction of a drum (4) is simulated; normal and extreme conditions such as non-load, no-load, heavy-load, clamping and secondary loading may be simulated; crack detection and strength checking may be carried out on the spindle device; defects such as spindle bending, spindle imbalance, and assembly loosening may be diagnosed; and the bearing performance of spindle devices having different spindle diameters, different wrapping angles, different numbers of steel cords and different wire rope intervals may be tested in a unified manner before such spindle devices are put into use. The testing device has a simple structure and reliable performance.
