Description
Technical field
The present invention relates to a kind of milling equipment, particularly a kind of roll vertical miller of roll shifting up and down of realizing.
Background technology
In recent years, along with China's rapid economy development, the people's the level of consumption improves constantly, and has greatly promoted civil buildings, automobile and other industries flourish.The increasing that government also does one's utmost is to the dynamics of investment of capital construction.As the benefited industry in the upper reaches, steel industry has obtained great development, but also industry production efficient is had higher requirement simultaneously, cuts down the consumption of energy and change, among the saving cost has been placed in the weight.In traditional vertical miller, roll can only utilize one section effective operation face of roll to being fixed in the rolling-mill housing left and right sides translation can not to go up and down in the operation of rolling; Make roll can only open single pass; And can only use once,, must change roll if on same rolling line, realize different rolled form; Cause the frequent change of roll, not only lose time and also more roll change system cause the many situations of the high waste of cost.How to increase the roll access times and extend working time, reduce the roll change number of times and just become the important problem that wherein needs to be resolved hurrily with the time.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide a kind of vertical miller of roll shifting up and down, can use the roll of the many scope of operations of porous type, reduce roller system and change number of times, improve roll service life and rolling efficiency.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of vertical miller of roll shifting up and down; Comprise mainly milling train body by rolling-mill housing 6, edger roll roller are 7, pressure tester 8 is formed; It is characterized in that: also comprise a lowering or hoisting gear; Said lowering or hoisting gear comprises base 1 and four columns that are arranged at 1 four jiaos of bases, and each column top respectively is connected with a lifting hydraulic cylinder 5, and the piston rod part of each lifting hydraulic cylinder 5 is equipped with two jacking nuts (3) and a locking nut (2) that accompanies a spacer (4) successively; Also be provided with the absolute altitude guiding mechanism that comprises step pad adjustment hydraulic cylinder 9, two stepped step pads 10 and a connecting rod 11 on the base 1; Connecting rod 11 is fixed between two step pads 10; Two step pads 10 are slidingly connected with base, and one of them step pad is fixedly connected with the piston rod that the step pad on being fixed in base is adjusted hydraulic cylinder 9; Said milling train body is located in the framework that four columns of lowering or hoisting gear base surround; The position of corresponding each column respectively is provided with a gudgeon 12 around the rolling-mill housing 6 of milling train body, and each gudgeon 12 is inserted in spacer 4 and is clamped locking by two jacking nuts 3 and a locking nut 2.
Further, below each gudgeon 12 of said rolling-mill housing 6, be provided with the right angle face 13 that contacts with base 1, corresponding base 1 all is equipped with slide plate 16 and matches.
Further, said base 1 two ends each vertical bearing pin 14 of installing also.
Further, the vertical bolt 15 of installing in the bottom of said each bearing pin.
Further, the bottom of said base 1 also is provided with slide mechanism.
Beneficial effect of the present invention is: the shortcoming that has not only overcome traditional structure; It is little that vertical miller frame body assembling up-down is required with respect to the change of vertical miller body, and roll can leave a plurality of passes, promptly increases the service life of roll; Can realize that again single milling train realizes that under the prerequisite of not changing roll many kinds are rolling; Reduce the number of times of more roll change system, can realize roller system is ejected fast, practice thrift the time of more roll change system and raise the efficiency the reduction use cost through lowering or hoisting gear.And the relative independence of lowering or hoisting gear makes the easy shortening time between overhauls(TBO) of installing/dismounting, and this lowering or hoisting gear can be applicable to simultaneously that milling train body steel wire rope is pulled out roll change and hydraulic cylinder is released roll change, when assembling, can not distinguish the difference of fore side and transmission side.

The specific embodiment
Below in conjunction with accompanying drawing the vertical miller and the use of roll shifting up and down of the present invention are explained:
As shown in Figure 6, vertical miller body of the present invention and traditional vertical miller structure are basic identical, mainly by rolling-mill housing 6, edger roll roller be 7 and pressure tester 8 form, present embodiment is an example with the edger roll roller system that two edger rolls are formed only, but is not limited thereto.
Like Fig. 4, shown in Figure 5; With the vertical miller body; Be installed in the framework of forming by the lifting hydraulic cylinder on the base of lowering or hoisting gear, four columns and the column; The upper cover of piston rod of each lifting hydraulic cylinder has jacking nut 3, spacer 4 and locking nut 2, and rolling-mill housing 6 corresponding columns are provided with four gudgeons 12, and gudgeon 12 is locked by jacking nut 3 and locking nut 2 jointly; Make the vertical miller body under lifting hydraulic cylinder drives, realize that locking nut 2 plays and loosens effect on jacking nut 3.
For rolling-mill housing being risen and descending more stable; Also be provided with slide mechanism between rolling-mill housing and four columns; Rolling-mill housing 6 also respectively is provided with edged surface 13 always in the present embodiment below each gudgeon 12; The slide plate that also is provided with said each column one side matches, and plays the effect of guiding and location.
The absolute altitude guiding mechanism comprises the absolute altitude guiding mechanism of step pad adjustment hydraulic cylinder 9, two stepped step pads 10 and a connecting rod 11; Connecting rod 11 is fixed between two step pads 10; Two step pads 10 are slidingly connected in two slideways with base; One of them step pad is fixedly connected with the piston rod that the step pad on being fixed in base is adjusted hydraulic cylinder 9, realizes translation by two step pads 10 in step pad adjustment hydraulic cylinder 9 drive bases 1 slideway with the absolute altitude guiding mechanism that connecting rod 11 is formed.
The absolute altitude position of adjustment rolling-mill housing assembling.
Workflow: as shown in the figure, lifting hydraulic cylinder 5 promotes two step pads with vertical miller body jack-up by step pad adjustment hydraulic cylinder 9; The different ladder heights of step pad are different, and when being pushed to required ladder height, step pad adjustment hydraulic cylinder 9 stops action; Lifting hydraulic cylinder is fallen; The rolling-mill housing bottom of vertical miller body is dropped on the ladder of corresponding height of step pad 10, and promptly roll is adjusted to relevant work pass position, and hydraulic cylinder continues to shrink and applies tightening force to rolling-mill housing; Rolling-mill housing is fixedly clamped in the framework of being made up of 1 four columns of base, makes milling train in the operation of rolling, keep the state of safety and stability.
On the rolling line that uses vertical miller, change roll like need, need earlier the milling train horizontal drawing to be broken away from production line, and then hang and change roll, for making things convenient for the whole horizontal drawing of milling train, base 1 two ends of lowering or hoisting gear are each vertical bearing pin 14 of installing also.Horizontal drawing connector (piston rod of steel wire rope or hydraulic cylinder) can be connected with bearing pin, drives the whole rolling translation through bearing pin.If steel wire rope pulls, also can be at the vertical installation in the bottom of each bearing pin one bolt 15, in order to avoid the steel wire rope landing.
Further, for reducing the frictional force of the whole horizontal drawing of milling train, also be provided with slide mechanism between the bottom of base 1 and the base anchor.
