Abstract
The utility model provides an eccentrically-supporting device of an integral roller. Specific to the integral roller, supporting rollers having supporting functions are installed in a paired and eccentric mode so that a casting blank can bear continuous and uniform load and the service life of the integral roller is greatly prolonged. The eccentrically-supporting device of the integral roller is characterized in that the two supporting rollers are eccentrically and symmetrically installed on the left side and the right side below the integral roller, and connection lines of axle centers of the integral roller and the two supporting rollers form an isosceles triangle. The left supporting roller and the right supporting roller are in a symmetrical triangular supporting type relative to the integral roller, can support the integral roller in the vertical direction, can prevent the integral roller from moving in a front-and-back mode in the horizontal direction, and can effectively bear alternating stress of the integral roller on the vertical degree of free and the horizontal degree of free.
Description
Technical field
The utility model relates to a kind of eccentric bracing or strutting arrangement of monoblock type roller, is specially the supporting construction and the device of monoblock type roller in the segments of slab section, belongs to metallurgy industry continuous casting installation for casting technical field.
Background technology
In the sheet billet continuous casting engineering of metallurgy industry; The roller of fan-shaped section has two types of whole roller and metamerism rollers, and conventional whole roller length≤1m is for the whole roller of length>=1m; Consider roll surface bearing load in the work greatly, particularly roller maximum deformation quantity≤0.5mm and the roller footpath specific (special) requirements that can not increase; Adopt the form of metamerism roller,, reach designing requirement (shown in accompanying drawing 1) through increasing the distortion that bearing block reduces roller.But adopt the metamerism roller form shown in the accompanying drawing 1, have following shortcoming: 1. increased bearing and bearing block, this has just increased input cost; 2. adopt the difficult processing of form of mandrel; 3. whole assembling relative complex of rollers, length consuming time and increased maintenance time; 4. because strand can not be supported in the position at bearing block place, the strand that often causes being positioned at the bearing block upper area produces the bulge phenomenon, is unfavorable for the steady quality of strand.
To above problem; Also be employed in the corresponding position of roll support face the backing roll mode is installed; Like Chinese invention patent " the carrying roller bracing or strutting arrangement of caster roll spare " (application number: 200710053735.0 applyings date: 2007-11-01) and utility model patent " the continuous casting roller of segments of slab section is a device " (application number: 200820154487.9 applyings date: 2008-10-27) disclosed technology; The weak point of this scheme is: above two kinds of schemes do not consider that all contradictory problems appears in the location arrangements of carrying roller and actual the use; The carrying roller ideal receives force direction to be in (carrying roller upwards to support is an example) under the carrying roller, but actual stressed be not all be vertically downward, the horizontal direction swing power of advancing along strand in addition influences; That is to say that carrying roller also will bear influences such as alternate stress in the course of the work; Therefore the carrying roller under being positioned at only is that the single direction that plays vertically upward supports the effect of monoblock type roller, in use has been difficult to effect preferably; Cause monoblock type roller fracture or damaged, shortened service life; On the other hand, the concentricity requirement of this mode when installing is very strict, gives and makes and install and bring great difficulty.
Summary of the invention
The purpose of the utility model is to ask a question to background technology; Propose a kind of eccentric bracing or strutting arrangement of monoblock type roller,, take in pairs and the passive carrying roller mode of eccentric installation to the monoblock type roller; Make carrying roller cross support monoblock type roller and bear alternate stress; Reach fine support effect, both made strand bear continuously load uniformly, the service life of having improved the monoblock type roller again greatly.
The technical scheme of the utility model is: the eccentric bracing or strutting arrangement of monoblock type roller; The bearing and the bearing block that comprise whole roller, whole roller two ends; Be positioned at two carrying rollers of below, whole roller middle part; Also be useful on the adjustment pad that carrying roller is installed, it is characterized in that: described two carrying rollers are eccentric and symmetry is installed in the left and right sides, whole roller below, and the line in whole roller and two carrying roller axle center is isosceles triangles.Its beneficial effect is: about two carrying rollers be the symmetrical triangular supporting way for whole roller; Both whole roller was played a supportive role in vertical direction; The front and back play that can stop whole roller again in the horizontal direction; On vertical and two frees degree of level, effectively carry whole roller alternate stress, improved whole roller service life.
Description of drawings
Accompanying drawing 1 is traditional metamerism roller mounting arrangements sketch map;
Accompanying drawing 2 is that the utility model embodiment monoblock type roller centering type is installed the carrying roller sketch map;
Accompanying drawing 3 is A in the accompanying drawing 2-A cutaway view;
Accompanying drawing 4 is B in the accompanying drawing 2-B cutaway view.
The specific embodiment
Mark in the accompanying drawing: in the accompanying drawing 1,1-bearing and bearing block, 2-mandrel, 3-roller; In accompanying drawing 2～accompanying drawing 4,4-whole roller, 5-left carrying roller, 6-right carrying roller, 7-sector-segment frames, 8-adjustment pad.
Below in conjunction with accompanying drawing the utility model embodiment is further specified:
Shown in accompanying drawing 2, the eccentric bracing or strutting arrangement of this reality invention monoblock type roller comprises the bearing and the bearing block 1 at whole roller 4, whole roller two ends; Be positioned at left carrying roller 5, the right carrying roller 6 of below, whole roller middle part, also be useful on the adjustment pad 8 that left and right sides carrying roller is installed, whole roller 4 is installed on the sector-segment frames 7 through bearing and bearing block 1; Left and right sides carrying roller (5,6) also is mounted on the sector-segment frames 7, and carrying roller eccentric also symmetry in the left and right sides is installed in the left and right sides, whole roller 4 below; The line in whole roller 4 and two carrying rollers (5,6) axle center is an isosceles triangle, and left carrying roller 5 axis are from whole roller 4 axis deviation distance b to the right, and right carrying roller 6 axis depart from b left from whole roller 4 axis; The adjustment pad is convenient to adjust the installation site of carrying roller; B=10mm in the present embodiment and since about two carrying rollers (5,6) be the symmetrical triangular supporting way for whole roller 4, so in vertical and horizontal direction; Left and right sides carrying roller (5,6) has all played whole roller 4 and has supported and prevention front and back play; Effectively carry whole roller alternate stress, make the deflection of whole roller 4 very little, improved 4 service lifes of whole roller.
Preferably, when whole roller total length during, can also be the carrying roller of installing more than two pairs greater than 2m, described carrying roller is respectively in 4 liang of downside symmetric arrangement of whole roller.
Preferably, the deviation distance b of carrying roller is adjustable, and its value can be 6～15mm.
The eccentric bracing or strutting arrangement of the new monoblock type roller of the utility model extensively model is applied in the sheet billet continuous casting engineering, in actual engineering, has adopted this new structure, and practical application effect is good, has realized good economic benefits.
