Hollow plate shaft assembly and rapid dismounting and mounting device thereof

The invention relates to a hollow plate shaft assembly and a fast dismounting and mounting device thereof. The hollow plate shaft assembly comprises a plate roller shaft arranged in a hollow plate roller in a sleeved mode; a belleville spring assembly used for locking the hollow plate roller on the plate roller shaft is arranged on one side of the hollow plate roller and sleeves the plate roller shaft; a clamping groove is formed in the position, located on the side, deviating from the hollow plate roller, of the belleville spring assembly, of the plate roller shaft; and at least one clamp spring used for locking the belleville spring assembly is clamped in the clamping groove. The hollow plate shaft assembly can be quickly dismounted and mounted, the working efficiency can be improved, the clamp springs are used for locking the belleville spring, the hollow plate roller is fixed by means of the elasticity of the belleville spring, and therefore looseness is not liable to occur. 本发明涉及种空心版轴组件及其快速拆装装置，该空心版轴组件包括
