Abstract
The invention relates to a novel vertical mill roll sleeve. The novel vertical mill roll sleeve comprises a roll sleeve body and two or more bosses, wherein the bosses are uniformly arranged on the inner circumference of the roll sleeve body; the two sides of each boss are provided with thread holes. The novel vertical mill roll sleeve has an improved vertical mill roll sleeve structure, the inner side of the vertical mill roll sleeve is provided with the two or more bosses, and during installation of the roll sleeve, the bosses are inserted into a roll core groove, so that the installation is accurate and convenient; when a vertical mill works, even though connecting bolts of a mill roll are loose, the plurality of bosses on the vertical mill roll sleeve also can effectively prevent the roll sleeve and a roll core from sliding relatively, so that the use is reliable; after the mill operates for a long time, the phenomenon of locking can occur on the roll sleeve and the conical surface of the roll core, and the disassembly is inconvenient, but when the roll sleeve is disassembled, the plurality of bosses are jacked by the bolts, and after the roll sleeve and the roll core are loosened, the lifting is finished by the thread holes in the bosses, so that the installation and the disassembly are convenient.
Description
Technical field
The present invention relates to a kind of vertical roller grinder technical field, relate in particular to a kind of vertical grinding roll cover.
Background technology
Vertical Mill, as a kind of main milling equipment, is widely used the occasions such as grinding raw material, cement, coal dust.Vertical Mill has stable mechanism performance, higher abrasive efficiency and longer life-span.Current, domestic vertical grinding roll cover is mostly conical surface tensioner form, roller shell inner side does not have or only has a key, when work, mainly rely on the expanding force of the vertical grinding roll cover conical surface, if the loosening relative sliding that just may occur roller shell and roller core of grinding roller connecting bolt, affect the service life of vertical grinding roll cover, when serious, can cause vertical grinding roll cover to destroy, affect the normal operation of grinding machine.
Summary of the invention
The invention provides a kind of more simple and reliable vertical grinding roll cover for above problem.
To the invention provides a kind of Novel vertical mill roller shell in order overcoming the above problems, to comprise roller shell body, boss, it is characterized in that: have to be more than or equal to the boss of two and to be evenly arranged on roller shell body inner periphery, and each boss both sides are provided with screwed hole.
Described screwed hole can be also a tapped through hole.
The present invention improves vertical grinding roll cover structure, and vertical grinding roll cover inner side is provided with the boss that is more than or equal to two, and when installation, multiple boss insert in roller core groove simultaneously, and it is accurately convenient to install; When Vertical Mill work, loosening even if grinding roller connecting bolt has, the multiple boss on vertical grinding roll cover also can effectively prevent that roller shell and roller core from having relative sliding, use reliable; After grinding machine long-play, roller shell and the roller core conical surface there will be " stuck " phenomenon, are inconvenient to dismantle, and this roller shell is in when dismounting, with a bolt successively boss at most, after roller shell and roller core unclamp, lift by crane by the screwed hole on boss, and installing/dismounting all more for convenience.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein, 1-roller shell body, 2-boss, 3-screwed hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, the invention provides a kind of Novel vertical mill roller shell, comprise roller shell body 1, boss 2, the boss 2 that is more than or equal to two is evenly arranged on roller shell body 1 inner periphery, and each boss 2 both sides are provided with screwed hole 3.
Different from traditional vertical grinding roll cover, there are two or more boss 2 this vertical grinding roll cover inner side, and boss 2 both sides are threaded hole 3.When roller shell is installed, lift by crane by the screwed hole 3 on multiple boss 2, multiple boss 2 insert in roller core groove simultaneously.
The foregoing is only the preferred embodiments of the present invention, be not restricted to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present invention.
