The abrasion-resistant triangular scraper comprises a hinged fork, an abrasion-resistant strip, a circular pin, a pin shaft, a scraper, a blocking plate and a web plate; two ends of the scraper are connected with the blocking plate; two ends of the blocking plate are connected with the hinged fork; the pin shaft is located in a groove of the hinged fork; the pin shaft is arranged on the hinged fork; the abrasion-resistant strip is welded on the working surface of the scraper in an embedded mode; the web plate which is arranged on the scraper is level with the abrasion-resistant strip. Compared with prior art, the abrasion-resistant position can be replaced to use and accordingly the service life of the scraper of the slag conveyor is extended, the slag conveying capacity of the scraper is increased, the friction of a slag conveyor wheel train is reduced, and accordingly the economic benefit is increased.
Description
Technical field
The utility model relates to a kind of scraper plate, specifically the wear-resisting triangle scraper plate of a kind of dragveyer.
Background technology
The scraper plate of existing dragveyer and hinge fork hardness are inadequate, easily wearing and tearing, between bearing pin and hinge fork, easily take off chain and cause parking accident, the wear rib arranging on scraper plate is vertical welding, cause wear rib to be more easily worn, seriously shorten the life-span of scraper plate, and scraper plate undercapacity, excessive velocities, defeated slag ability is little.
Utility model content
The purpose of this utility model is to provide a kind of dragveyer wear-resisting triangle scraper plate, to solve the problem proposing in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
The wear-resisting triangle scraper plate of a kind of dragveyer, comprise hinge fork, wear rib, round pin, bearing pin, scraper plate, closure plate, web, the two ends of described scraper plate connect closure plate, the two ends connecting hinge fork of scraper plate, bearing pin is positioned at the groove of hinge fork, and it is upper that described bearing pin is arranged on hinge fork, and bearing pin is between two hinge forks, described wear rib welding-on is on the working face of scraper plate, and web on scraper plate flushes with wear rib.
As further program of the utility model: described hinge fork adopts through the heat treated forging hinge of over carburizing fork, and the material of hinge fork is CrMnTi steel alloy.
As further program of the utility model: described bearing pin adopts the 45# steel through Quenching Treatment and hardness HRC >=60.
As further program of the utility model: described wear rib downhand welding is at the working face of scraper plate, and wear rib adopts the deposition techniques wear resistant composite alloy bar that macrohardness HRC is 58～62.
As further scheme of the utility model: described closure plate two ends are all than the long 70～80mm in scraper plate body two ends.
Compared with prior art, the beneficial effects of the utility model are:
1. hinge fork adopts Forging Technology hinge fork, material selection CrMnTi steel alloy, scrape slab integral and adopt precision die-forging forming technology, hinge is pitched internal structure densification, intensity is high, without the intrinsic defect of casting hinge fork self, to forge hinge fork and add the Technologies for Heating Processing such as lonneal through carburizing and quenching, wearability and intensity have all obtained improving significantly, and between hinge fork and bearing pin, adopt the spacing anti-rotation measure of groove, thoroughly solved the problem that between bearing pin and hinge fork, wearing and tearing come off.Bearing pin adopts through 45# steel Quenching Treatment and hardness HRC >=60, has good wearability, has improved its service life, has avoided because of the disastershutdown that bearing pin comes off, the de-chain of scraper plate causes.
2. the Type of Welding of wear rib changes downhand welding into by original vertical position welding, i.e. welding-on import high abrasion (micro-hardness HV >=1750 on the working face (both sides up and down of angle steel) of scraper plate, macrohardness HRC is 58～62) deposition techniques wear resistant composite alloy bar, after wear rib wearing and tearing, can may wear to scraper plate body, strengthen the anti-wear performance of scraper plate, increase the service life, wear rib has recoverability, changes wear-resisting edge strip and can reuse after wearing and tearing; And the facade epiplastron at scraper plate flushes with wear rib, is also beneficial to the whereabouts of lime-ash, scraper is 4～5 times of traditional screeds service life.
3. the closure plate at scraper plate two ends is all lengthened to 70～80mm, after lengthening, can form U-shaped slag chute with the scraper flight top of the slag, increase the defeated slag ability of scraper plate, corresponding exerting oneself of increasing equipment, after using this structure, can on former basis, exert oneself more than 25% by increase equipment, the equipment of can solve is exerted oneself not or the too fast problem of scraper velocity; If the dragveyer of normal operation is used this kind of blade structure instead, after can making the speed of service slow down, the rotating speed of all trains that are in contact with it slows down and chain wear amount reduces, and has increased the service life of train and chain scraper.
