Description
Technical field
A kind of steel rail straightening roller is the utility model is related to, belongs to metallurgy industry heavy rail finishing equipment technical field.
Background technology
At present, Rail Production enterprise is typically all that rail is aligned using flat vertical compound roll leveller, so as to obtain
Obtain high straightness rail.Flat vertical compound roll leveller is made up of Horizontal weld type straightener and vertical roll leveller.Level is rectified
Straight machine is aligned in vertical direction to rail, and vertical straightening machine is aligned in the horizontal direction to rail.Wherein vertical aligning
Machine is made up of eight smoothing rolls, and the smoothing roll of seven identical passes acts on rail head side of rail, and a plain-barreled roll acts on rail
Waist.Vertical straightening machine smoothing roll is monoblock type smoothing roll, and referring to the drawings 1, the vertical smoothing roll of monoblock type exists such as in production
Lower problem：
（1）Recoverability is poor after damage, the vertical smoothing roll working face of monoblock type usually occurs and chip off-falling occurs, but can not repair
Again, it is necessary to the situation that whole branch roller is scrapped；
（2）Turnery amount is big, because each turning needs to carry out turning to whole branch smoothing roll, even if not producing abrasion
Protection face also want turning, turnery amount is larger；
（3）Use cost is high, because recoverability is poor after its damage, needs overall turning after abrasion, and use cost is higher.
Utility model content
The utility model purpose is to provide a kind of special Split type vertical smoothing roll of rail, and integral vertical type smoothing roll is changed to point
The vertical smoothing roll of body, cost is low, and recoverability is good, and Lathe quantity is small, solves problem present in background technology.
The technical solution of the utility model is：
A kind of special Split type vertical smoothing roll of rail, comprising rail, edger roll mandrel, edger roll building ring, edger roll pad and stand
Roller guide circle, edger roll building ring, edger roll pad and edger roll guide collar, institute are sequentially provided with from top to bottom on the outer surface of edger roll mandrel
The rail head profile of the pass and rail of stating edger roll building ring matches, and the diameter of edger roll guide collar is more than the diameter of edger roll pad.
The contact surface of the edger roll building ring and rail head side of rail is the inclined-plane being engaged with rail head side of rail, edger roll
The contact surface of building ring and rail head of rail lower jaw is the inclined-plane being engaged with rail head of rail lower jaw.
The edger roll pad and the outer face of edger roll guide collar are engaged with the web of the rail of rail.
The edger roll mandrel is provided with collars centre bore along axis, and centre bore is sheathed in the rotating shaft of transmission device.
Keyway is provided with collars centre bore on the edger roll mandrel axis.
Using the utility model, vertical straightening machine smoothing roll needs to repair or worn needs turning afterwards to a certain extent
When, the building ring of smoothing roll need to only be repaired or turning, change flexible, turnery amount is small.
The beneficial effects of the utility model are：Should be Split type vertical smoothing roll by integral vertical type smoothing roll, while to aligning
Roller aperture type is modified, and makes the shape of its rail head of rail that more coincide, leveling effect is better than prior art smoothing roll aligning effect
Fruit.It is simple in construction firm, change flexibly, use cost is low, and recoverability is good, and turnery amount is small, remarkable in economical benefits.

Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 2-5, a kind of special Split type vertical smoothing roll of rail, rail 1, edger roll mandrel 3, edger roll building ring are included
4th, edger roll pad 5 and edger roll guide collar 6, edger roll building ring 4, edger roll are sequentially provided with from top to bottom on the outer surface of edger roll mandrel 3
Pad 5 and edger roll guide collar 6, the pass of the edger roll building ring 4 and the rail head side profile of rail 1 are matched, and edger roll is oriented to
The diameter of circle 6 is more than the diameter of edger roll pad 5.
In the present embodiment, referring to the drawings 3, the thickness of edger roll building ring 4 is 77.83mm, edger roll building ring 4 and rail 1
The gradient of rail head side contacting portion is consistent with the rail head side wall slope of rail 1, and edger roll building ring 4 contacts with the rail head lower jaw of rail 1
Partial gradient is consistent with the rail head lower jaw gradient of rail 1, i.e., the pass of edger roll building ring 4 just coincide with the rail head profile of rail 1.
Referring to the drawings 4, the thickness of the edger roll pad 5 between edger roll guide collar 6 and edger roll building ring 4 is 10-25mm, is stood
