The invention provides a vertical shaft hoisting crown wheel bearing performance detection device comprising a steel wire rope, a support bearing pedestal, vertical foundations, a vertical side hydraulic loading device, a tilt side hydraulic loading device, a locating plate and horizontal foundations. The horizontal foundations are arranged horizontally and transversely in parallel. The locating plate is arranged on the upper surface of the horizontal foundations. The vertical foundations are symmetrically erected on the outer side of the horizontal foundations. The support bearing pedestal islongitudinally arranged across the vertical foundations along a horizontal direction. The vertical side hydraulic loading device and the tilt side hydraulic loading device are installed on the horizontal foundations through the locating plate. The two ends of the steel wire rope are respectively connected into a vertical side lock sleeve and a tilt side lock sleeve. The crown wheel can be integrally loaded within the enclosure angle range to simulate normal and extreme working conditions such as no load, empty load, heavy load, tank jamming, secondary loading and the like, crack detection andstrength check can be performed on the crown wheel and unified bearing performance detection can be performed on the crown wheel with different diameters and enclosure angles before service, and thestructure is simple and the performance is reliable.
