Description
Technical field
The utility model belongs to technical field of metallurgical equipment, and particularly a kind of self-adapting type is directed laterally to mechanism.Especially walking cooling bank self-adapting type is directed laterally to mechanism.
Background technology
As the intermediate link being connected steel-making and steel rolling process, continuous casting plays vital effect in whole technological process, and the quality of continuous cast products quality directly determines the competitiveness of enterprise product, is the key link of Business survival.Step-by-step movement turn over cooling bed is as one of the key equipment of continuous cast products Shape Quality Control, and it has become one of necessary equipment of long scale casting machine.No matter be electronic cold bed or hydraulic pressure cold bed, its stepping and turnover technology are all very ripe, and present stage, ubiquitous problem was cold bed framework sideslip in running, and framework entirety may be caused time serious to fall rail.The applying working condition of this and cold bed has direct relation, the strand scale that cold bed transports is generally at 8-16m, cause tooth plate support frame huge, the deflection deformation of equipment self, alignment error and Synchronization Control error inherently can bring certain running deviation value, in addition the unbalance loading that strand different length causes more exacerbates the sideslip of framework, if do not have good lateral guide to be rectified a deviation, just there will be framework damage even overall fall the severe accident of rail.The side guiding mechanism of current cold bed, substantially be all the two-way sideslip adopting paired guide wheel to carry out control framework, reserved certain gap between each wheel tread and rail level, it is discontiguous for ideally running, only have when running deviation value reaches gap width, directive wheel just retrains framework.But because equipment is huge, very easily cause equipment to be installed and accuracy of manufacture deficiency, cause the guide effect of cold bed not ideal enough.Being directed laterally to wheel guide beam can only be stoped to offset further aggravation in addition in current structure, can not play automatic aligning function; Although guiding sideshake is very little, device length is large, and in sideshake allowed band, the head of equipment, afterbody beat are still very large, run the problem such as jam, device damage so still there will be.
Therefore, how improving stability and the service life of step-by-step movement turn over cooling bed operation, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
Order of the present utility model is to provide a kind of self-adapting type to be directed laterally to wheel mechanism, solves in cold bed running the problem occurring to offset.Can also reduce the installation accuracy requirement of cold bed guiding mechanism, can also carry out eccentricity compensation after directive wheel surface abrasion, this also substantially increases stability and the service life of equipment simultaneously.
A kind of self-adapting type is directed laterally to wheel mechanism, comprises guide rail 1, guiding wheels 2, damping buffer unit 3, firm banking 4, cold bed step rate 9; Guide rail 1 is fixed on step rate 9, and guiding wheels 2 are established in guide rail 1 both sides, and the one end away from guide rail 1 and the firm banking 4 of guiding wheels 2 are connected and fixed; Between guiding wheels 2 and firm banking 4, have at least side to be provided with damping buffer unit 3, damping buffer unit 3 flexible, its elastic deformation direction is perpendicular to the side of described guide rail 1, and the expansion end of damping buffer unit 3 is connected with the guiding wheels bearing 201 of guiding wheels 2.By compression and the release of damping buffer unit 3, realize moving forward and backward of directive wheel, directive wheel 202 tread belonging to guide wheel assemblies 2 contacts with rail level all the time, rectifies a deviation while guiding to cold bed step rate 9.
Described damping buffer unit 3 is driven by elastic damper or disc spring, air spring drive.
Described damping buffer unit 3 adopts two end flanges to fix, and namely stiff end is connected with firm banking 4, and movable end is connected with the guiding wheels bearing 201 of guiding wheels 2.
The guide wheel shaft 203 of described guiding wheels 2 is eccentric shaft, is compensated alignment error and the wear extent of guide wheel tread and rail level in using of directive wheel by its eccentric throw.
Described firm banking 4 is provided with spigot surface, carries out flexible guiding to guiding wheels 2, and that bears the generation of guide wheel tread place rolls the moment of resistance simultaneously.
Described guiding wheels 2 of the prior art are rigidly fixed on base 4, under normal circumstances, certain interval is set between two directive wheels 202 and guide rail 1, gap width is reached once cold bed step rate 9 position offset, skew side directive wheel 202 just can retrain it and continue sideslip, but correction can not be forced to cold bed step rate 9, occur unless there are reserve migration.The sideshake track of cold bed step rate 9, depends on the load change of self, arbitrarily swings in the scope that sideshake allows, and causes cold bed step rate 9 to run not steady, affects the service life of equipment.
A kind of self-adapting type provided by the utility model is directed laterally to mechanism, its left and right directive wheel 202 adjusts automatically according to guide rail 1 side-play amount, when the biasing force of cold bed step rate 9 is greater than the reaction force that damping buffer unit 3 provides, damper is compressed, skew is aggravation further, when the biasing force of cold bed step rate 9 is less than the reaction force that damping buffer unit 3 provides, damper will elastic recovery, to the skew of cold bed step rate 9 be rectified a deviation and just return, thus solve above-mentioned problems of the prior art.
The utility model has the advantage of: the precision and stability greatly improving guiding, installation and the maintenance load of equipment can be reduced simultaneously, the stability that the equipment that substantially increases runs and service life.
