The utility model content
Can't automatic centering at the above-mentioned roller-way that exists in the prior art, the shortcoming of moving about, cause backplate wearing and tearing and influence to produce about the band steel is easy, the purpose of this utility model provides a kind of spray hot rolling conveying roller road, and this roller-way can carry out automatic centering to the band steel that moves about.
For achieving the above object, the utility model adopts following technical scheme:
This hot rolling line conveyor roller comprises the roller that several are identical and be arranged side by side, and described roller all is designed to two circular cone stage bodies coaxial and tapering does not wait, and the smaller diameter end of the circular cone stage body that the larger diameter end of the circular cone stage body that tapering is big and tapering are little is connected; The installation direction of described adjacent two rollers is opposite.
The equal diameters of the smaller diameter end of the circular cone stage body that the diameter of the larger diameter end of the circular cone stage body that described tapering is big and tapering are little and overlapping is connected and fixed.
All be on the side of the circular cone stage body that described tapering is little and be horizontally disposed with.
The equal in length of the circular cone stage body that the length of the circular cone stage body that described tapering is big and tapering are little.
In technique scheme, hot rolling line conveyor roller of the present utility model comprises the roller that several are identical and be arranged side by side, this roller all is designed to coaxial and two circular cone stage bodies that tapering does not wait, and the smaller diameter end of the circular cone stage body that the larger diameter end of the circular cone stage body that tapering is big and tapering are little is connected; And the installation direction of adjacent two rollers is opposite.The roll surface speed of roller-way both sides that adopts this roller arrangements is greater than the roll surface speed of roller-way center line near zone, band steel in transportation takes place when a side is moved about, can be pushed to the roller-way middle part automatically by roller, thereby realization automatic centering, avoid the roller-way both sides to wear and tear, strong assurance rhythm of production, increased economic benefit, also effectively eliminated the heap steel accident that time the step operation takes place.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Fig. 3～5, hot rolling line conveyor roller 20 of the present utility model equally also comprises the roller 21 that several are identical and be arranged side by side, unlike the prior art be, this roller 21 all is designed to two coaxial and tapering does not wait circular cone stage body 21a, 21b, the equal diameters of the smaller diameter end of the circular cone stage body 21b that the diameter of the larger diameter end of the circular cone stage body 21a that tapering is big and tapering are little, and coincide and be connected and fixed.The equal in length of the circular cone stage body 21b that the length of the circular cone stage body 21a that tapering is big and tapering are little that is to say that the junction of two circular cone stage body 21a, 21b is positioned on the center line of this roller-way 20.The installation direction of adjacent two rollers 21 of this roller-way 20 is opposite, and all rollers 21 are alternately arranged all the time in this way side by side.Upper end, the side of the circular cone stage body 21b that the tapering of all rollers 21 is little in addition 212 all is and is horizontally disposed with, thereby constitutes the horizontal roll surface in both sides of roller-way 20.Also there are following characteristics in the roller-way 20 arranged of roller 21 thus: the axis of adjacent two rollers 21 is to reporting to the leadship after accomplishing a task mutually and having less angle; The upper end 211, side of the circular cone stage body 21a that tapering is big is a little less than the upper end, side 212 of the little circular cone stage body 21b of tapering; Therefore, from the vertical view (Fig. 3) of whole roller-way 20, the upper end roll surface of this roller-way 20 is broadly divided into following three zones: the I zone level is provided with, and linear velocity maximum, the II zone is also for being horizontally disposed with, but linear velocity relatively and the I zone less, and the III zone is downward-sloping, highly be lower than I, II zone, and the linear velocity minimum.Therefore, when adopting this roller-way 20 to be used to be with steel 1 transportation, in case band steel 1 is when roller-way 20 1 sides are moved about, band steel 1 contacts with the I zone of this side, because the linear velocity in this side I zone is greater than the linear velocity in the II zone at roller-way 20 middle parts, therefore can push band steel 1 to roller-way 20 middle parts automatically, thereby realize the automatic centering function, guarantee to be with steel 1 to carry along roller-way 20 center lines, and the III of this side zone is because lower always, do not contact, so can not influence the centering effect with band steel 1.
After adopting hot rolling line conveyor roller 20 of the present utility model; substantially eliminated the phenomenon that band steel about 1 moves about; thereby band steel 1 bump even wearing and tearing backplate have been avoided; also reduce the band steel 1 correction operation of non-programmed halt; help guaranteeing the hot rolling rhythm of production; improve operating efficiency, increased economic benefit.In addition, also eliminated because of band steel 1 head sideslip enters down the step operation and caused heap steel accident, and improved on-line measurement and followed the tracks of The conditions of calculation, effect is very remarkable.
