Description

Technical Field

[0001] The utility model provides a safety platform for maintenance of a gyratory crusher, and relates to the technical field of safety. Background Art

[0002] Gyratory crushers have the advantages of high productivity, low power consumption, relatively stable operation, low vibration, large crushing ratio, and uniform product particle size, and are now widely used in large mines. Gyratory crusher linings need to be replaced periodically after wear. Due to the large volume of the moving cone, when replacing the moving cone lining, the lower shaft diameter of the moving cone must be placed vertically in the pit to reduce the height of the moving cone and improve the stability of the moving cone placement. In this state, the height of the moving cone is 3-4m, which brings great difficulties to the removal and installation of the lock cap and the moving cone lining. The commonly used method is to set up a steel pipe scaffolding for maintenance work. This method is time-consuming and labor-intensive to install, and the safety factor is low, which brings greater safety risks to maintenance personnel when replacing the lining.
