The utility model content
In order to overcome the defective of above-mentioned prior art, technical problem to be solved in the utility model provides a kind of roll change efficient height, the milling train of remaining silent with changing rig that mobile stationarity is good.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of milling train of remaining silent with changing rig comprises base, is fixed on rolling-mill housing on the base, is assemblied in the roll assembly on the rolling-mill housing and is fixed on roll change mechanism on the base.
Described base is provided with by rolling-mill housing to the horizontally extending guide rail of roll change mechanism;
Described rolling-mill housing comprises transmission side memorial archway and fore side memorial archway, and the height of the lower bolster of transmission side memorial archway is greater than the height of the lower bolster of fore side memorial archway;
Described roll assembly comprises roll, transmission side bearing block and fore side bearing block, described transmission side bearing block is assemblied on the lower bolster of described transmission side memorial archway, described fore side bearing block is assemblied on the lower bolster of described fore side memorial archway, the axial line of described roll is in level, the bottom of described roll assembly is provided with roller, described roll assembly cooperates along described guide rail with the rolling of guide rail by described roller and moves, and described roll assembly is provided with bail in the side near described roll change mechanism;
Described roll change mechanism comprises hydraulic cylinder, and the piston rod of described hydraulic cylinder is connected with described bail.
Wherein, the height of the lower bolster of described transmission side memorial archway is greater than the height 6mm of the lower bolster of described fore side memorial archway.Accordingly, also there are the difference in height of 6mm in transmission side bearing block and fore side bearing block bottom surface.
Wherein, described roller is when steel rolling is produced and leave the gap of 5mm between the described guide rail.
Wherein, described guide rail has two, is set in parallel on the described base; Be provided with two rollers corresponding to every guide rail, described roller is set in parallel in the bottom of described roll assembly.
The utlity model has following beneficial effect: because the height of the lower bolster of transmission side memorial archway is greater than the height of the lower bolster of fore side memorial archway, when the needs roll change, when transmission side bearing block process fore side memorial archway, the phenomenon that the lower bolster of the bottom of transmission side bearing block and fore side memorial archway is collided can not take place, make the roll change process smooth, improved roll change efficient and mobile stationarity.

The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.
See also Fig. 1 and Fig. 2, the milling train of remaining silent with changing rig of present embodiment comprises base 1, is fixed on rolling-mill housing 2 on the base 1, is assemblied in the roll assembly 3 on the rolling-mill housing 2 and is fixed on roll change mechanism 4 on the base 1.
Described base 1 is provided with by rolling-mill housing 2 to roll change mechanism 4 horizontally extending guide rails 10.
Described rolling-mill housing 2 comprises transmission side memorial archway 20 and fore side memorial archway 21, and the height of the lower bolster 200 of transmission side memorial archway 20 is greater than the height of the lower bolster 210 of fore side memorial archway 21.Preferably, the height of the lower bolster 200 of described transmission side memorial archway 20 is greater than the height 6mm of the lower bolster 210 of described fore side memorial archway 21.
Described roll assembly 3 comprises roll 30, transmission side bearing block 31 and fore side bearing block 32, described transmission side bearing block 31 is assemblied on the lower bolster 200 of described transmission side memorial archway 20, described fore side bearing block 32 is assemblied on the lower bolster 210 of described fore side memorial archway 21, and the axial line of described roll 30 is in level.Because the height of the lower bolster 200 of transmission side memorial archway 20 is greater than the height of the lower bolster 210 of fore side memorial archway 21, for the axial line that makes roll 30 is in level, can correspondingly the bottom of fore side bearing block 32 be exceeded the identical numerical value in bottom of transmission side bearing block 31: such as the height of the lower bolster 200 of the transmission side memorial archway 20 height 6mm greater than the lower bolster 210 of described fore side memorial archway 21, then the bottom of fore side bearing block 32 exceeds the bottom 6mm of transmission side bearing block 31.
The bottom of described roll assembly 3 is provided with roller 33, and described roll assembly 3 cooperates along described guide rail 10 with the rolling of guide rail 10 by described roller 33 and moves.Further, described roller 33 is when roll 30 work and leave the gap of 5mm between the described guide rail 10, when being roll 30 work roller 33 unsettled above guide rail 10 the 5mm place, like this when roll change, roll assembly 3 will slide 1 segment distance earlier, whereabouts 5mm, roller 33 could contact with guide rail 10.Moreover since the height of the lower bolster 200 of transmission side memorial archway 20 greater than the height 6mm of the lower bolster 210 of described fore side memorial archway 21; the existence of this " difference in height "; make and when transmission side bearing block 31 moves to fore side memorial archway 21 places, can not blocked by lower bolster 210; thereby need not to force one section height of pulling lifting just can pass through smoothly; guarantee that the roll change process carries out smoothly and can not produce vibration and impact, improve roll change efficient and mobile stationarity.
Described roll assembly 3 is provided with bail 34 near a side of described roll change mechanism 4, and described roll change mechanism 4 comprises hydraulic cylinder 40.The piston rod of described hydraulic cylinder 40 is connected with described bail 34.By the movement of piston rod, it is mobile at guide rail 10 to drive roll assembly 3.
In the above-described embodiments, described guide rail 10 is preferably two, is set in parallel on the described base 1; Be provided with two rollers 33 corresponding to every guide rail 10, described roller 33 is set in parallel in the bottom of described roll assembly 3, thereby improves mobile stationarity.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
