The purpose of this utility model is achieved in that
An auxiliary support apparatus for cement mill, comprises base, and described base is provided with along the axially extended mounting groove of grinding machine roller, some carrying rollers be parallel to each other evenly are provided with in this mounting groove, the side face of each carrying roller all contacts with the outer peripheral face of grinding machine roller, forms supplemental support
Also comprise a kind of supporting seat for supporting this base, this supporting seat comprises connecting plate, rubber buffer, support, described support comprises top board, base plate and biside plate, top board, base plate is parallel to each other, biside plate is welded on top board respectively, the both sides of base plate, form the frame structure in isosceles trapezoid, the base plate of support is provided with the trimming bolt for adjusting pole height, described connecting plate is fixed on above support by a connecting bolt, the two ends of described connecting bolt are connected to connecting plate, in the middle part of rack plate, described rubber buffer is positioned at connecting plate, between support, connecting bolt runs through rubber buffer.
A support plate is fixed at the both ends of described carrying roller, the lower end of each support plate arranges a guide post, the axial line of guide post passes the axial line of carrying roller, grinding machine roller, and each guide post is all snug fit at the pilot hole that base is provided with, and arranges Compress Spring between at the bottom of the hole of each guide post and pilot hole;
Described guide post is notch cuttype, described pilot hole is the notch cuttype corresponding with guide post, the intersegmental gap in large footpath of guide post is engaged in the large footpath section of pilot hole, and the intersegmental gap of path of guide post is engaged in the path section of pilot hole, and described Compress Spring is enclosed within the path section of guide post.
The outer peripheral face of described rubber buffer is dentation.
The screw rod end of described trimming bolt runs through the base plate of support downwards, and coordinates with the base thread of support, and the screw rod of trimming bolt welds for reducing the gripper shoe to geostatic pressure through one end of support base plate.
The quantity of described trimming bolt is three, and wherein two trimming bolts are positioned at the two ends of support base plate, and another trimming bolt is positioned at the centre of support base plate.
Owing to have employed technique scheme, the utility model has following beneficial effect:
The length of the axis of carrying roller is longer, and, make the contact area of the cylinder of carrying roller and cement mill larger, great compressing can not be caused to the cylinder local of cement mill, prevent compressive deformation in the drum functions process of cement mill, even damaged, extend the use longevity of cement mill cylinder.
Carrying roller is relative to only using for bearing, better tightness, can prevent dust from entering bearing, the dust that bearing in carrying roller is in area that this dust in cement plant concentrates also can not be gathered, and then make to keep minimum friction between the roller of the bearing in carrying roller and inside and outside circle, make the life-span of the bearing in carrying roller longer, reduce use cost.
A support plate is fixed at the both ends of carrying roller, and the lower end of each support plate arranges a guide post, and the axial line of guide post, through the axial line of carrying roller, grinding machine roller, makes the guide post direction that is stressed consistent with own axes direction, prevents guide post from damaging by shearing.Each guide post is all snug fit at the pilot hole that base is provided with, between at the bottom of the hole of each guide post and pilot hole, Compress Spring is set, form elasticity support plate, make carrying roller can provide flexible support to the cylinder of cement mill, the trace vibration that the cylinder absorbing cement mill produces in the course of the work, and, under the effect of Compress Spring, carrying roller and grinding machine roller continuous close contact, rigid collision can not be produced, the cylinder of cement mill can not compressive deformation, even damaged, extends the service life of cement mill cylinder.
Support is the isosceles trapezoid frame structure be welded and fixed, and intensity is high, not yielding, has good support effect, can reduce installing space again.Connecting plate is fixed on above support by a connecting bolt, the two ends of connecting bolt are connected in the middle part of connecting plate, rack plate, rubber buffer is between connecting plate, support, and connecting bolt runs through rubber buffer, and is positioned on the axial line of rubber buffer.Therefore; connecting plate can produce swing when stressed; suffered power is passed to rubber buffer; rubber buffer can accept the pressure that all directions are subject to; thus absorb the vibration of cement mill cylinder generation; rubber buffer had both play a part to support grinding machine roller weight, again can at grinding machine roller because vibration plays buffer protection function by during excessive generation instantaneous stress.The trimming bolt that the base plate of support is provided with, can adjusting pole height, ensures that base plate is positioned on horizontal plane, to adapt to the installation question that ground injustice causes, enables connecting plate firmly connect grinding machine roller.The outer peripheral face indention of rubber buffer, makes rubber buffer not easily excessive deformation occur when pressurized, improves the service life of rubber buffer.
The utility model is to provide a power upwards to the cylinder of cement mill on the one hand, prevent its flexural deformation under gravity, absorb the vibration produced in the drum functions process of cement mill on the other hand, prevent the both ends of cylinder impaired, make cylinder not fragile, longer service life.
