Number in the figure is as follows: working roll bearing block 1, butterfly spring 2, fastening bolt 3, bottom guide 4, flower basket bolt 5, block 6, adjust pad 7, cushion block 8, steel wire rope 9, under scrape phosphorus plate 10, slot 11.
The specific embodiment
The utility model is made up of cushion block 8, adjustment pad 7, fastening bolt 3, butterfly spring 2, flower basket bolt 5, steel wire rope 9, block 6.
In figure, show, have slot 11 in the outside of working roll bearing block 1, the bottom of cushion block 8 is bolted in the lower end of slot 11, installs and adjust pad 7 and bottom guide 4 on cushion block 8.
In figure, show, vertical fastening screw is arranged at the top of cushion block 8, the end of bottom guide 4 is embedded in the slot 11 of working roll bearing block 1, between the upper surface of the bottom surface of the end of bottom guide 4 and cushion block 8, there is the pad 7 of adjustment, all there is vertical through hole bottom guide 4 ends with on adjustment pad 7, bottom guide 4 ends and the through-bore axis of adjusting on pad 7 overlap with the fastening screw axially bored line on cushion block 8 tops, and fastening bolt 3 is connected with the fastening screw on cushion block 8 tops through bottom guide 4 end through holes, adjustment pad 7 through holes from top to bottom.
In upper figure, show, the vertical through hole of bottom guide 4 ends is slotted eye, and slotted eye is used for the compensation bolt causing because of bearing block locked position difference and the deviation that bolt hole misaligns, and is convenient to fastening bolt 3 and interts installation.
In figure, show, the nut below of fastening bolt 3 is set with butterfly spring 2, and butterfly spring 2 lower ends withstand on bottom guide 4 end upper surfaces.Compacted butterfly spring 2 becomes flexible or upsprings and cause gap variation because the elastic resistance of self can prevent the bottom guide 4 that vibratory impulse causes in rolling process, tightens after fastening bolt 3, and butterfly spring 2 just plays fastening effect for the first time to bottom guide 4.
In figure, show, adjusting pad 7 is multi-layer gasket, can adjust as required.
In figure, show, steel wire rope 9 two ends be looped around respectively bottom guide 4 and bearing block bottom under scrape on phosphorus plate 10, in the middle of steel wire rope 9, connect flower basket bolts 5.By flower basket bolt 5, steel wire rope 9 and the molecular annular fastening device of wire clips, by bottom guide 4 be fixed on be arranged on bearing block bottom under scrape on phosphorus plate 10, due to right-handed thread, the left hand thread structure of flower basket bolt 5 uniquenesses, by the frame structure at rotation flower basket bolt 5 middle parts, this annular fastening device can be tightened up, bottom guide 4 is played to fastening effect for the second time.
In figure, show, below bottom guide 4 ends, be welded with block 6, block 6 is in the position of adjusting between pad 7 and flower basket bolt 5.
An embodiment of the present utility model is as follows:
Adopt the fixing cushion block 8 of hexagon socket head cap screw level on slot 11 of M16x90;
The oval-shaped through-hole diameter 30mm of bottom guide 4 ends;
Fastening bolt 3 is the outer-hexagonal bolt of M24x320 or M24x300;
The thickness of cushion block 8 is 55mm, is having vertical fastening bolt holes apart from cushion block 8 32mm places of limit portion, and aperture is M24, the effective length 38mm of screwed hole;
Distance is adjusted pad 7 32mm places of limit portion the through hole of diameter 30mm;
There is M20 screwed hole at the rotating frame two ends of flower basket bolt 5, and top is right-handed thread, and bottom is left hand thread, the hook portion of flower basket bolt 5, and the part of buckle is right-handed thread, the part of band is left hand thread;
Assembling process of the present utility model is as follows:
Support the use steel wire rope 9 and the rope clip of diameter 10mm, by flower basket bolt 5, steel wire rope 9 and the molecular annular fastening device of wire clips, by bottom guide 4 be fixed on be arranged on working roll bearing block 1 bottom under scrape on phosphorus plate 10.Due to right-handed thread, the left hand thread structure of flower basket bolt 5 uniquenesses, by the frame structure at rotation flower basket bolt 5 middle parts, this annular fastening device can be tightened up, bottom guide 5 is played to fastening effect for the second time.
Along with reducing of roller diameter, the quantity of the adjustment pad 7 assembling also can reduce thereupon, on the contrary butterfly spring 2 quantity of installation to increase, can select the fastening bolt 3 of shorter length, in order to avoid butterfly spring 2 quantity are too many or other fault of the oversize initiation of fastening bolt 3 simultaneously.On the other hand, because the screw buckle length of flower basket bolt 5 is certain, when being reduced to a certain degree of roller diameter, need to regulate the length of steel wire rope 9, the girth of flower basket bolt 5, steel wire rope 9 and the molecular annular fastening device of wire clips is reduced, better fastening bottom guide 4.
