Description

Slide block type oxygen lance slag scraper

Technical Field

The utility model belongs to the technical field of steel industry steelmaking process equipment technique and specifically relates to a slider formula oxygen rifle scum ware.

Background

The oxygen lance is the main component equipment of converter steelmaking system, and the smelting process often appears the slag and adheres to on the oxygen lance, needs one kind to scrape sediment ware equipment and assists and scrapes the slag that glues on the oxygen lance, and present sediment ware equipment is generally promoted rocking arm tool bit by the cylinder and is close to the oxygen lance outer tube and scrape the sediment, and when the oxygen lance is lumpy great or the bonding steel is more, the tool bit atress is greater than cylinder thrust and makes the cylinder return, can't continue effectively to scrape the sediment, and scrape the sediment dynamics undersize, can not guarantee to scrape the sediment effect. And the agglomeration of the oxygen lance can be slowly increased, so that the risk of pulling out the sealing port of the oxygen lance in the lance lifting process exists. In addition, poor slag scraping effect also causes the oxygen lance not to work according to a determined service life, and further increases the labor intensity of lance repair personnel.

SUMMERY OF THE UTILITY MODEL

The utility model provides a slider formula oxygen rifle slag scraping device, it can solve the current problem of scraping the slag device dynamics not enough.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the device comprises two cutters driven by cylinders, wherein the two cylinders are respectively and oppositely fixedly arranged at two ends of a guide rail support frame, sliding grooves are formed in the inner sides of cross beams at two sides of the guide rail support frame, and two sides of each cutter driven by the cylinders are in sliding connection in the sliding grooves.

In the above technical solution, a more specific solution may also be: the guide rail support frame comprises cross beams on two sides, baffles at two ends and a supporting foot at the bottom, the corresponding positions of the inner sides of the cross beams on two sides of the middle section of the guide rail support frame are arranged in a concave arc shape, and two rib plates are symmetrically and transversely arranged at the outer sides of two ends of the concave arc position at the top end of the guide rail support frame; the baffle is used for fixedly mounting the cylinder body.

Further: the cutter comprises a blade head and a cutter joint, the blade head comprises two sliding blocks with the head parts inclining towards each other, a blade is fixedly inserted at the top end of the blade head, and the cutter joint is connected with a telescopic rod of the air cylinder.

Further: and a guide wheel is arranged on the side edge of the cutter in sliding connection in the sliding groove.

Further: two baffle middle sections are equipped with the breach that cylinder block body diameter size suited, are equipped with a pair of cylinder supporting shoe that is used for the fixed connection cylinder in this breach both sides, and this is equipped with the fore shaft that is used for locking the staple bolt of cylinder block body to the corresponding position of cylinder supporting shoe.

Due to the adoption of the technical scheme, compared with the prior art, the utility model, have following beneficial effect:

because the cutter is arranged on the guide rail support frame provided with the sliding groove, the cutter moves in the sliding groove through the horizontal pushing and retraction of the cylinder, so that the slag scraping force is greatly improved, and the slag scraping effect is good; even also can guarantee the smooth and easy operation of cutter under the more abominable operating mode environment of long-pending sediment, and cylinder thrust is used for scraping the sediment by original directness and changes into and only is used for promoting the cutter motion, has alleviateed work burden greatly, and the cylinder life-span improves by a wide margin.

The serial numbers are as follows:

the device comprises an air cylinder 1, a cross beam 2, a cutter joint 3, a rib plate 4, a guide wheel 5, a slide block 6, a blade 7, a baffle plate 8, an air cylinder supporting block 9, a supporting foot 10, a sliding groove 11 and an anchor ear 12.

Detailed Description

The present invention will be described in further detail with reference to the following examples. However, the present invention is not limited to the following examples.

As shown in fig. 1 to 5, the present embodiment includes two cutters driven by two cylinders 1, the two cylinders 1 are respectively and relatively fixedly arranged at two ends of a guide rail support frame, the inner sides of beams 2 at two sides of the guide rail support frame are provided with chutes 11, two sides of the cutter driven by each cylinder 1 are slidably connected in the chutes 11, the guide rail support frame includes the beams 2 at two sides, baffles 8 at two ends and supporting feet 10 at the bottom, the corresponding positions at the inner sides of the beams 2 at two sides of the middle section of the guide rail support frame are arranged in a concave arc shape, as shown in fig. 3, two rib plates 4 are symmetrically and transversely arranged at the outer sides of the two ends of the concave arc position at the top end; the baffle 8 is used for fixedly mounting the cylinder body of the cylinder 1; the cutter consists of a blade head and a cutter joint 3, the blade head consists of two sliders 6 with the heads inclining in opposite directions, a blade 7 is fixedly inserted at the top end of the blade head, the cutter joint 3 is connected with a telescopic rod of the cylinder 1, and a guide wheel 5 is arranged on the side edge of the cutter which is in sliding connection with the sliding chute 11, so that the cutter can slide in the sliding rail more smoothly; two 8 middle sections of baffle be equipped with the breach that cylinder block body diameter size suited is equipped with a pair of cylinder supporting shoe 9 that is used for fixed connection cylinder 1 in this breach both sides, and this is equipped with the fore shaft to the corresponding position of cylinder supporting shoe 9, and the crimping has staple bolt 12 on this fore shaft, and staple bolt 12 locks the cylinder block in the breach that 8 middle sections of baffle were equipped with, when needs change the cylinder, only need turn round the staple bolt and open, can take off the cylinder, and it is convenient to change.

When the oxygen lance is used, the cylinders 1 at the two ends push the sliding block 6 and the blade 7 to be in a closed state, the slag adhered to the lance body is scraped off in a sheet mode under the action of the blade 7 when the oxygen lance is lifted, and the guide rail limits the sliding block 6 and the blade 7 to move vertically upwards during slag scraping, so that the maximum slag scraping force is provided; after the oxygen lance slag scraping is finished, the sliding block 6 and the blade 7 are pulled reversely by the cylinder to be in an open state, and then the oxygen lance enters a next slag scraping standby state.

Willow steel 3# converter has used this novel slider formula oxygen rifle to scrape sediment ware, compares original old sediment ware of scraping, scrapes the sediment dynamics and has had very big promotion, scrapes the sediment respond well, even also can guarantee the smooth and easy operation of cutter under the more abominable operating mode environment of long-pending sediment, and cylinder thrust is used for scraping the sediment by original directness and changes into only being used for promoting the cutter motion, has alleviateed work burden greatly, and the cylinder life improves by a wide margin.
