Abstract
The utility model relates to a novel vertical mill roll sleeve comprising a roll sleeve body and two or more than two bosses, the bosses are arranged on the inner circumference of the roll sleeve body uniformly, and threaded holes are formed in two sides of each boss. The novel vertical mill roll sleeve has the advantages that by the aid of an improved vertical mill roll sleeve structure, the bosses are arranged on the inner side of the roll sleeve and are inserted into roll core grooves at the same time during mounting, so that mounting is accurate and convenient; when a vertical mill is operated, even if mill roll connection bolts are loosened, the bosses on the vertical mill roll sleeve can also prevent relevant slide of the roll sleeve and a roll core effectively, and thereby the novel vertical mill roll sleeve is reliable to use; after long-time operation of the vertical mill, 'jamming' of the roll sleeve and a roll core conical surface can occur to enable demounting to be inconvenient, and the roll sleeve is demounted by ejecting the bosses by the bolts sequentially and being lifted by the threaded holes in the bosses after the roll sleeve and the roll core are loosened, thereby being quite convenient to mount and demount.
Description
Technical field
The utility model relates to a kind of vertical roller grinder technical field, relates 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.
Utility model content
Provide a kind of more simple and reliable vertical grinding roll cover for above problem the utility model.
Provide a kind of Novel vertical mill roller shell in order to overcome the above problems the utility model, comprised 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 have been provided with screwed hole.
Described screwed hole can be also a tapped through hole.
The utility model improvement vertical grinding roll cover structure, 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 utility model.
Wherein, 1-roller shell body, 2-boss, 3-screwed hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model provides a kind of Novel vertical mill roller shell, comprises roller shell body 1, boss 2, and 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 preferred embodiment of the present utility model, be not restricted to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
