Abstract
The utility model provides a kind of slag scraper of converter oxygen lance.The utility model comprises travelling car, U-shaped bearing is installed on described travelling car, the zygomorphy of described U-shaped bearing is installed respectively hydraulic ram, two cantilevers are installed in the bottom of described U-shaped support, described cantilever is by hinged between guide rail pole and the piston rod of described hydraulic ram, before each cantilever, scraper is installed in inner side, and outside is connected with described travelling car by telescopic boom.The utility model integral rigidity is good, and working stability is scraped slag efficiency high.
Description
technical field:
The utility model relates to a kind of slag scraper of converter oxygen lance, belongs to converter support equipment technical field.
background technology:
Steel adhesion on oxygen lance is ubiquitous phenomenon in converter steelmaking production process, in converting process, steel adhesion on oxygen lance can cause oxygen rifle heat dissipating state to worsen, oxygen lance blow head is easily burned, also can cause oxygen lance lifting difficulty simultaneously, easy-to-draw bad oxygen rifle nitrogen sealing, when serious, oxygen rifle is carried not plug for outlet, affects normal smelting operation.
Conventional oxygen rifle slagging-off adopts the cooling scarfing cinder of water spray or manually slagging-off, and due to the cooling scarfing cinder of spraying water frequently, the main oxygen-blowing gun outer tube of every block converter is less than 3000 stoves work-ing life.When simultaneously artificial scarfing cinder, in cutting scarfing cinder process, also can there is the landing of slag cover, cut slag and splash and hurt sb.'s feelings and oxygen gun body cuts the logical phenomenon such as leak, have larger potential safety hazard.
In order to address the above problem, Chinese patent 201020062488.8 discloses a kind of Y type oxygen rifle skim gate, and specifically disclose following technical characterictic: this Y type oxygen rifle skim gate is made up of V type cylinder saddle, cylinder, axle, pivoted arm, slagging-off cutter, supporting base and bearing pin, skim gate is Y type in working order time, and left and right two pivoted arms rotate in supporting base by axle; Slagging-off cutter uses screw to be connected with pivoted arm; Left and right cylinder is arranged on V type cylinder saddle.This employing cylinder promotes cantilever, and slagging-off cutter is arranged on to the slagging-off mode on cantilever, in use because reactive force is very large, works extremely unstable in the process of scraping slag, and accident is frequently continuous, and problem is urgently to be resolved hurrily.
utility model content:
The purpose of this utility model is to provide a kind of slag scraper of converter oxygen lance for the problem of above-mentioned existence, and integral rigidity is good, and working stability is scraped slag efficiency high.
Above-mentioned object realizes by following technical scheme:
Slag scraper of converter oxygen lance, comprise travelling car, U-shaped bearing is installed on described travelling car, the zygomorphy of described U-shaped bearing is installed respectively hydraulic ram, two cantilevers are installed in the bottom of described U-shaped support, described cantilever is by hinged between guide rail pole and the piston rod of described hydraulic ram, and scraper is installed in inner side before each cantilever, and outside is connected with described travelling car by telescopic boom.
Described slag scraper of converter oxygen lance, described telescopic boom comprises the rigid rod one being connected by bearing pin with described travelling car and the rigid rod two being connected by bearing pin with described cantilever, between described rigid rod one and described rigid rod two, connects by bearing pin.
Described slag scraper of converter oxygen lance, adopts bearing pin to be connected between described cantilever and described U-shaped bearing.
Described slag scraper of converter oxygen lance, between described guide rail pole and described cantilever, for being fixedly connected with, the angle between described guide rail pole and described cantilever is 30 °-60 °.
Described slag scraper of converter oxygen lance, described scraper is that semicircle is ring-like.
Beneficial effect:
1. the utility model has increased telescopic boom between cantilever and travelling car, makes to form tetragon between cantilever, telescopic boom and travelling car, has increased the rigidity of cantilever in the process of scraping slag, makes dregs scraper overall work stable, scrapes slag efficiency high.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
In figure 1, travelling car; 2, U-shaped bearing; 3, hydraulic ram; 4, cantilever; 5, guide rail pole; 6, scraper; 7, rigid rod one; 8, rigid rod two.
embodiment:
Embodiment 1:
As shown in Figure 1, the slag scraper of converter oxygen lance of the present embodiment, comprise travelling car 1, U-shaped bearing 2 is installed on described travelling car, the zygomorphy of described U-shaped bearing is installed respectively hydraulic ram 3, and two cantilevers 4 are installed in the bottom of described U-shaped support, and described cantilever is by hinged between guide rail pole 5 and the piston rod of described hydraulic ram, before each cantilever, scraper 6 is installed in inner side, and outside is connected with described travelling car by telescopic boom.The guide rail pole of the present embodiment adopts the inside to be provided with the form of slideway, a slide block is set on the piston rod of hydraulic ram, in the flexible process of oil cylinder, slide block can be in slideway slide inside, otherwise hydraulic ram cannot stretch, and also just cannot realize the folding of two semicircles annular scrapers.
Described slag scraper of converter oxygen lance, described telescopic boom comprises the rigid rod 1 being connected by bearing pin with described travelling car and the rigid rod 28 being connected by bearing pin with described cantilever, between described rigid rod one and described rigid rod two, connects by bearing pin.The length sum of guide rail pole one and guide rail pole two is greater than the tie point of guide rail pole one and dolly to the slant range between guide rail pole two and the tie point of cantilever, due in the process of work, cantilever will move back and forth under the driving of hydraulic ram, and angle between guide rail pole one and guide rail pole two also becomes large thereupon or diminishes.
Described slag scraper of converter oxygen lance, adopts bearing pin to be connected between described cantilever and described U-shaped bearing.
Described slag scraper of converter oxygen lance, between described guide rail pole and described cantilever, for being fixedly connected with, the angle between described guide rail pole and described cantilever is 30 °-60 °.
Described slag scraper of converter oxygen lance, described scraper is that semicircle is ring-like.And in actual selection scraper, to select according to the specification of oxygen rifle, make the internal diameter of annulus that two ends pipeline forms altogether and the outside dimension of oxygen rifle quite or be slightly larger than external diameter 1-2mm the best of oxygen rifle.
Working process, when need to scraping slag, primer fluid compressing cylinder, under the promotion of hydraulic ram, cantilever drives scraper to clamp, and in the process moving up, realizes and scrapes slag at oxygen rifle, scrape slag complete with post shrinkage hydraulic ram, hydraulic ram drives two scrapers to unclamp, the oxygen rifle state of resuming work.In the process of work, telescopic boom plays the effect that strengthens cantilever rigidity, and working stability is reliable, and the utility model designs on travelling car, can be as required, remove after scraping slag, use very flexibly, and do not take up space, do not affect the work such as conventional maintenance and maintenance of oxygen rifle.
The disclosed technique means of the utility model scheme is not limited only to the disclosed technique means of above-described embodiment, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belongs to those skilled in the art's common practise.
