Abstract
The utility model relates to a rotary kiln supporting structure, which comprises a roller axle and a supporting roller mounted at the upper end of the roller axle, wherein steps are arranged at both ends of the roller axle, and stop piece mounting slots are arranged on the steps; the rotary kiln supporting structure is characterized in that the outer side of the mounting slots on the roller axle is wider than the inner side of the mounting slots. In the structure, the outer side of the mounting slots is modified to be wider than the inner side of the mounting slots on the premise that the axial length of the steps of the original roller axle remains unchanged, so that the mechanical strength of the steps at the end parts of the roller axle of the rotary kiln is improved; when the condition of the rotary kiln is changed, and the force borne by the supporting roller exceeds the design limit, the two ends of the roller axle of the rotary kiln can be prevented from being damaged, so that the maintenance probability of the equipment is reduced and the working efficiency of the equipment is improved.
Description
Technical field
The utility model belongs to production cement and uses the apparatus for rotating technical field, particularly relates to a kind of rotary kiln supporting construction.
Background technology
At present, the key equipment rotary kiln supports rotating operation by supporting roller of rotary kiln on the cement producing line, and the support roller fixed-site is motionless; Because rotary kiln is in tilted layout horizontal by 3.5 degree, during the rotary kiln rotation, rotary kiln is supported support roller produce oblique component; When the rotary kiln working conditions change occurring, support roller is stressed when exceeding design limit, and the end side of supporting roller of rotary kiln axle will be destroyed; Can not play fixedly support roller effect, cause the rotary kiln support system to destroy, supporting roller of rotary kiln is scrapped; The supporting roller of rotary kiln that need more renew is with the stopping production loss that causes about 5 days, about 200,000 yuan of direct economic losses.If design a kind of supporting roller of rotary kiln again, the end side of supporting roller of rotary kiln axle is no longer destroyed, avoid support roller to change, will produce than the large economy benefit.
Summary of the invention
The utility model is for solving the rotary kiln supporting construction that the technical problem that exists in the known technology provides a kind of long service life, reduces production and use cost.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of rotary kiln supporting construction comprises supporting-roller shaft, is installed in the support roller of supporting-roller shaft upper end, and the two ends of supporting-roller shaft are provided with step, and step is provided with the block mounting groove, it is characterized in that: the width in the mounting groove outside on the said supporting-roller shaft is greater than the inboard width of mounting groove.
Advantage and the good effect that the utlity model has are: because the utility model adopts said structure; Promptly under the constant situation of the step axial length that guarantees original supporting-roller shaft; The width in the mounting groove outside is changed into greater than the inboard width of mounting groove, thus the end step mechanical strength of raising supporting roller of rotary kiln axle, when the rotary kiln working conditions change occurring; Support roller is stressed when exceeding design limit; Guarantee that supporting roller of rotary kiln axle two ends are not damaged, thereby reduce the apparatus maintenance probability, improve the operating efficiency of equipment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, supporting-roller shaft; 1-1, step; 1-2, mounting groove; 2, support roller.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of rotary kiln supporting construction comprises supporting-roller shaft 1; Be installed in the support roller 2 of supporting-roller shaft 1 upper end; The two ends of supporting-roller shaft 1 are provided with step 1-1, and step 1-1 is provided with block mounting groove 1-2, and the width in the mounting groove 1-2 outside on the said supporting-roller shaft 1 is greater than the inboard width of mounting groove 1-2.
Said structure is under the constant situation of the axial L1 length of step that guarantees original supporting-roller shaft; The width L3 in the mounting groove outside is changed into greater than the inboard width L2 of mounting groove, thus the end step mechanical strength of raising supporting roller of rotary kiln axle, when the rotary kiln working conditions change occurring; Support roller is stressed when exceeding design limit; Guarantee that supporting roller of rotary kiln axle two ends are not damaged, thereby reduce the apparatus maintenance probability, improve the operating efficiency of equipment.
