Detailed Description

Fig. 1~3 is a preferred embodiment of the present invention, which is further illustrated in conjunction with 1~3.

A grinding disc dismounting device (hereinafter referred to as grinding disc dismounting device) of a vertical mill speed reducer comprises a main frame, and as shown in a graph 1~2, the main frame of the grinding disc dismounting device comprises a horizontally arranged dismounting arm. The disassembly arm comprises two main clamping plates 3 which are arranged side by side from front to back, two clamping blocks 4 are respectively arranged at two ends between the main clamping plates 3, and the main clamping plates 3 at the front side and the back side and the clamping blocks 4 at two ends of the main clamping plates 3 are sequentially fixed into a whole. The outer end faces of the clamping blocks 4 at the two ends are respectively fixed with a hanging ring 1, and the hanging rings 1 at the two ends of the dismounting arm are respectively fixed with a hoisting crane 7.

Two sides of the dismounting arm are respectively and symmetrically provided with a fixing bolt 8, and the two fixing bolts 8 respectively vertically penetrate through the gap between the two main clamping plates 3. And a group of gaskets 2 respectively corresponding to the two fixing bolts 8 are respectively and symmetrically arranged on two sides of the dismounting arm. Each set of the spacers 2 includes an upper spacer located on the upper surface of the detaching arm and a lower spacer located on the lower surface of the detaching arm, and the upper spacer and the lower spacer are respectively sleeved on the outer ring of the fixing bolt 8 from the upper portion and the lower portion of the corresponding fixing bolt 8. A fixing nut 10 in threaded connection with the fixing bolt 8 is respectively arranged above each upper gasket, and a fixing nut 10 in threaded connection with the fixing bolt 8 is respectively arranged below each lower gasket. The fixing bolts 8 are fixed with the dismounting arms by the gaskets 2 and the fixing nuts 10 which are positioned at the upper side and the lower side of each fixing bolt 8. A protective cover 5 is arranged below the middle part of the dismounting arm, and the top of the protective cover 5 penetrates through the gap between the two main clamping plates 3 and then is fixed with a reinforcing plate 6 positioned above the main clamping plates 3.
