For the above situation, to overcome the defect of the prior art, it is an object of the invention to provide a kind of wearing layer is removable
The wear resistant roll unloaded, can effectively solve that existing wear resistant roll is easy to wear, and inconvenient maintenance, maintenance time is long, the problem of influencing production efficiency.
The technical solution that the present invention solves is a kind of dismountable wear resistant roll of wearing layer, including roll body, locating rod, first
Wear member, the second wear member, washer and hard alloy plug have the first positioning groove and first on the cylindrical surface of the roll body
Threaded hole has the second threaded hole on side；The locating rod is mutually agreed with the first positioning groove size shape；Described first is wear-resisting
There is the second positioning groove, third threaded hole and through-hole mutually agreed with locating rod size shape on component；The second wear-resisting structure
There is the third positioning groove and the 4th threaded hole mutually agreed with locating rod size shape on part；The roll body and the first wear member
It is positioned by locating rod with the second wear member, is linked together by screw, constitute wearing layer；The hard alloy plug can be embedded in
In the through-hole of first wear member, smooth flat is constituted.
The present invention is arranged dismountable wear member and forms wearing layer, has following advantageous effects：1. wearing layer is ground
It need not be repaired by built-up welding after damage；Wear resistant roll need not integrally be removed when 2. repairing, wear member can be carried out
It replaces, substantially increases remediation efficiency；3. repairing efficiency is short, and the equipment for not needing profession is repaired, and has significant economy
And social benefit.

Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings.
As described in Fig. 1-Fig. 4, a kind of dismountable wear resistant roll of wearing layer of the present invention, including roll body 1, locating rod 2, first are resistance to
Component 3, the second wear member 4, washer 5 and hard alloy plug 6 are ground, has 7 He of the first positioning groove on the cylindrical surface of the roll body 1
First threaded hole 8 has the second threaded hole 9 on side；The locating rod 2 is mutually agreed with 7 size shape of the first positioning groove；It is described
There is the second positioning groove 10, third threaded hole 11 and the through-hole mutually agreed with 2 size shape of locating rod on first wear member 3
12；There is the third positioning groove 13 and the 4th threaded hole mutually agreed with 2 size shape of locating rod on second wear member 4
14；The roll body 1 and the first wear member 3 are positioned with the second wear member 4 by locating rod 2, are linked together by screw, structure
At wearing layer；The hard alloy plug 6 can be embedded in the through-hole 12 of the first wear member 3, constitute smooth flat.
The length of the locating rod 2 is equal to the length of 1 maximum radius cylinder of roll body.
The roll body 1 is axial to be uniformly distributed four the first positioning grooves of circle 7；Often circle is uniformly distributed 8 the first positioning grooves 7.
The length direction of second positioning groove 10 and the angle of the T shapes side apart from nearest first wear member 3 are
10°。
The length direction of the third positioning groove 13 and the angle of the T shapes side apart from nearest second wear member 4 are
