Abstract
The utility model discloses a scraping device for a vertical mill. The scraping device comprises a base, a scraping plate and a pin shaft, wherein the base is fixedly hinged to the scraping plate through the pin shaft; the scraping plate is a square plate body; more than two scraping plate lifting lugs are arranged at one end of the scraping plate, and are integrated with the scraping plate; corresponding scraping plate lifting lug holes are formed in the scraping plate lifting lugs; base lifting lugs are arranged below the base, wherein the number and the positions of the base lifting lugs are corresponding to those of the scraping plate lifting lugs; the base lifting lugs are integrated with the base; corresponding base lifting lugholes are formed in the base lifting lugs; the pin shaft penetrates through the scraping plate lifting lug holes and the base lifting lug holes to hinge the base and the scraping plate. The scraping device has the advantages that the connection is reliable, the assembly, the disassembly and maintenance are convenient, the service life is long, and interference scratches between the scraping device and an enclosure of the vertical mill are completely eradicated.
Description
Technical field:
The utility model relates to a kind of use equipment of Vertical Mill, relates in particular to a kind of Vertical Mill scraper.
Background technology:
Vertical Mill is in operation, and because adopting two material scraping plates to be bolted structure, connecting bolt fracture often occurs, and the material scraping plate that is positioned at bottom comes off, and cannot realize scraping function; Material scraping plate and base shackle shaft are to infinite place, and material scraping plate shifting amount is too large, produce to scratch interfere with Vertical Mill casing; Have a strong impact on normal production; Meanwhile, bearing pin is axially without fixture, and spindle nose is welded, and can only take cutting to renew maintenance, and cost is high, and because of narrow space, maintenance difficult, labour intensity is large.
Utility model content:
The purpose of this utility model is to provide a kind of and connects reliable, easy disassembly, maintenance, long service life, stops the Vertical Mill scraper that scraper and Vertical Mill casing are interfered scratch.
The utility model is implemented by following technical scheme: Vertical Mill scraper, it comprises base, material scraping plate and bearing pin, described base and described material scraping plate are hinged fixing by described bearing pin, described material scraping plate is a square plate body, in described material scraping plate one end, be provided with plural material scraping plate hanger, described material scraping plate hanger and described material scraping plate are into a single integrated structure, are provided with corresponding material scraping plate hanger hole on described material scraping plate hanger; Below described base, be provided with the base hanger corresponding with described material scraping plate hanger quantity and position, described base hanger and described base are into a single integrated structure, are provided with corresponding base hanger hole on described base hanger; Described bearing pin is through described material scraping plate hanger hole and described base hanger hole, and described base and described material scraping plate is hinged; Described material scraping plate hanger fits tightly with corresponding described base hanger.
In described bearing pin one end, be provided with gear platform, described gear platform and described bearing pin are into a single integrated structure, be provided with external screw thread, and be bolted with nut at the described bearing pin other end, on the described bearing pin other end and described nut, are movably equipped with pin.
In described base hanger hole, be provided with wear-resistant sleeve, described bearing pin is through described wear-resistant sleeve.
Advantage of the present utility model: material scraping plate and material scraping plate hanger adopt integrative-structure, and intensity is high, extends material scraping plate service life; In base hanger hole, design wear-resistant sleeve, is convenient to maintain and replace, extends base service life; Improve base, material scraping plate, the radial and axial quality of fit of bearing pin, stop scraper and Vertical Mill casing and interfere scratch; End part of pin shaft adopts nut to add pin combining structure and fixes, and connects reliably easy disassembly and maintenance again, and bearing pin is reusable, cost-saving; Scraper stable and reliable operation, whole service life increases greatly.
