Abstract
The utility model relates to heavy and medium plate cold or hot flatteners and heat treating flatteners used in metallurgy industry, in particular to a flattener edge roll lifting gear which mainly solves the technical problems of providing a flattener edge roll anti-seizing lifting gear for preventing iron scale from entering into a lifting shaft sleeve. The flattener edge roll anti-seizing lifting gear comprises a supporting roll positioned under an edge roll, wherein the lifting shaft of a supporting roll bearing seat is installed on a sliding sleeve seat of a lower roll seat frame, and a protecting cover is arranged between the sliding sleeve seat and the boss of the lifting shaft. The edge roll anti-seizing lifting gear of the utility model can prevent the iron scale from entering into the lifting shaft sleeve and being deadly locked, and reduce various friction, further, the edge roll can be adjusted real-timely when bearing load or not during production process, thereby being favorable to controlling plate shapes.
Description
Technical field
The utility model relates to the hot and cold straightener of cut deal that metallurgy industry uses, the limit roller lowering or hoisting gear of heat treatment straightener, especially straightener.
Background technology
On the Heavy Plate Production line of metallurgy industry, straightener because the iron scale on the band steel comes off, will be piled up below straightener in process of production.And the limit roller needs on-load to adjust in real time in the straightener production process, and the iron scale of accumulation falls into the lifting shaft sliding sleeve of limit roller backing roll easily, and influence is adjusted, and is serious even cause lifting shaft stuck.Setting-out washes iron scale in often adopting now, and iron scale is along with the flushing of middle setting-out, and tiny iron scale is easier to fall into the lifting shaft sliding sleeve, so result of use is relatively poor always.
The utility model content
Technical problem to be solved in the utility model provides a kind of straightener limit roller anti-sticking lowering or hoisting gear that can stop iron scale to enter the lifting shaft sliding sleeve.
The straightener limit roller anti-sticking lowering or hoisting gear that its technical problem that solves the utility model adopts, comprise the backing roll that is installed in below the roller of limit, the lifting shaft of back-up chock is installed on the sleeve base of lower roll mounting, between the boss of sleeve base and lifting shaft protective cover is installed.
As a kind of improvement of the present utility model, described protective cover is flexible eclipsed form protective cover.
As another kind of improvement the of the present utility model, described protective cover comprise be installed on the boss on overlap and be installed in trapping on the sleeve base, described go up be sleeved on trap on.
As further improvement of the utility model, described sleeve base is the frustum on band slope.
Adopt limit of the present utility model roller anti-sticking lowering or hoisting gear can prevent that iron scale from entering the lifting shaft sliding sleeve and avoiding stuck, reduce friction everywhere, the limit roller can be adjusted when on-load or idling lotus in real time in the production process, helps the control of plate shape.And reduce owing to the stuck maintenance that causes of lifting shaft, downtime, improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The last cover of mark among the figure: 1-, 2-limit roller, the 3-boss, the 4-sleeve base, 5-traps, 6-lifting shaft, 7-sliding sleeve, 8-backing roll, 9-mud hole, 10-swash plate, 11-limit roller seat frame, 12-limit roll bearing seat, 13-lower roll mounting, 14-slope.
The specific embodiment
Straightener limit roll bearing seat 12 is installed on the limit roller seat frame 11, and can adjust the working depth of limit roller 2 up and down.The bottom of limit roller 2 is equipped with backing roll 8, and the lifting shaft 6 of the bearing block of backing roll 8 is installed in the sleeve base 4 of lower roll mounting 13, and lifting shaft 6 is provided with boss 3, and the bearing block of backing roll 8 is installed in boss 3.Between lifting shaft 6 and slide cover 4, be provided with sliding sleeve 7,, will influence the normal adjustment of lifting shaft 6 in the aligning process if the iron scale that produces etc. are fallen in the sliding sleeve 7, even stuck lifting shaft 6.
Between the boss 3 of sleeve base 4 and lifting shaft 6, protective cover is installed, lifting shaft 6 is in the airtight space, prevented that the iron scale that drops from above from falling into sliding sleeve 7, impacts sliding sleeve 7.
Embodiment 1:
Consider from common structure, protective cover is set to the flexible eclipsed form protective cover made as plastics, rubber or other chemical materials, Height Adjustment along with lifting shaft 6, it is the variable in distance between boss 3 and the sleeve base 4, protective cover also can change length thereupon, guarantees that lifting shaft 6 is in the airtight space.
Embodiment 2:
For the hot steel plate of aligning, because the iron scale temperature is very high easily to plastics, materials such as rubber cause damage, and straightener is in the very narrow and small abominable working environment in hot and humid space again, adopt the structure of embodiment 1, not only can't install on the structure, and be restricted and influence its service life, so as shown in Figure 1, protective cover comprises that being installed in going up cover 1 and being installed on the boss 3 traps 5 on the sleeve base 4, the described cover 3 of going up is sleeved on and traps on 5, no matter lifting shaft 6 is adjusted to any operating position, last cover 1 all have partial-length with trap 5 overlapping, and go up cover 1 and the as far as possible little scope that does not influence its proper motion is adjusted in the gap of trapping between 5, therefore iron scale be difficult to from last cover 1 and the gap between 5 of trapping enter into lifting shaft 6 around, just can not exert an influence yet, importantly can conveniently install sliding sleeve 7.
In above-mentioned two embodiment, all exist because after straightener work a period of time, iron scale increases, around protective cover, form accumulation, thereby influence the operate as normal of protective cover, even cause the partial oxidation iron sheet to enter into protective cover inevitably, therefore as shown in Figure 1, sleeve base 4 is designed to frustum with slope 14, iron scale will be along the slope 14 bottoms of falling lower roll mounting 13, reduce the accumulation around protective cover.
Generally be provided with mud hole 9 in the bottom of lower roll mounting 13, the iron scale of the iron scale that produces below mud hole 9 is discharged to reclaims hole or the collection box, therefore the bottom on the slope 14 of sleeve base 4 is corresponding with mud hole 9 positions on the lower roll seat 13, iron scale just can fall into mud hole 9 than more smoothly.As shown in Figure 1, for the lifting shaft 6 at straightener two ends, because mud hole 9 is arranged on the side near the middle part, therefore the slope 14 with sleeve base 4 is set to the single gradient; And for the lifting shaft 6 at middle part, because mud hole 9 all is provided with in the both sides of sleeve base 4, therefore the slope 14 with sleeve base 4 is set to the mud hole 9 of both direction the gradient is arranged all.
Because limit roller seat frame 11 and lower roll mounting 13 adopts weldments, consider from welding procedure, between the slope 14 of sleeve base 4 and mud hole 9, be provided with swash plate 10, be more conducive to iron scale and fall into mud hole 9.
