Description
Technical field
The utility model relates to guider, especially relate to a kind of for the Slab Caster Dummy Bar car, adjustable dummy bar centering guider.
Background technology
Along with the development of national economy and smelting iron and steel technology, more and more higher to the requirement of smelting iron and steel quality and efficient.In the sheet billet continuous casting field, dummy bar is that one of visual plant that waters left by conticaster, its effect is the interior end that forms crystallizer in cast advances into crystallizer, after the cast beginning, the molten steel in the crystallizer condenses in dummy bar, by the traction of withdrawal straightening machine, strand is pulled out from the crystallizer end opening continuously with dummy bar, until strand enters withdrawal straightening machine, after dummy bar and strand broke away from, conticaster entered normal throwing state.The load mode of existing Slab Caster Dummy Bar is divided into two kinds of dress formula and down-mounting types, the dummy bar car is one of main equipment of upper dress formula Dummy Bar System, its function is that dummy bar is transported to the crystallizer top, is inserted into the crystallizer from crystallizer is suitable for reading.The dummy bar car owner will be comprised of car body, running gear, dummy bar centering guider, driving-chain and driving-chain tension-adjusting gear etc.Wherein, dummy bar centering guider carries out the side guiding for the process of transporting dummy bar at driving-chain to dummy bar, thereby makes dummy bar can accurately enter crystallizer inside.
Existing dummy bar centering guider mostly is a square bloom, its direct and dummy bar contacts side surfaces formation sliding friction, dummy bar length is longer, rubbing action is just more, damage to dummy bar is just larger, and along with the maximization of conticaster, dummy bar is more and more longer, therefore dummy bar transporting apart from also more and more longer on driving-chain need more reliable centralising device.
Summary of the invention
The utility model mainly is for the existing above-mentioned technical problem of prior art, provides a kind of simple in structure, the adjustable guiding device less to its frictional dissipation in the centering guiding process of dummy bar.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of dummy bar centering guider, comprise the centering guide holder, and described centering guide holder top is provided with guide wheel, and the bottom is fixedly connected with drive unit.The utility model is installed in entrance side and the outlet side of dummy bar car upper driving chain, is used for dummy bar is carried out the centering guiding, makes it move to crystallizer inside along the direction that limits.Guide pad on traditional centralising device is a square steel, its direct and dummy bar contacts side surfaces formation sliding friction, and dummy bar length is longer, and rubbing action is just more, and is just larger to the damage of dummy bar.On the utility model centering guide holder guide wheel is installed; this guide wheel is the free roll that rotates around fixed central spindle; between guide wheel and the mandrel rolling bearing is housed; make the guide wheel freedom that can go slick; contact with dummy bar by guide wheel; make sliding friction become rolling friction, reduce friction, the protection dummy bar.In addition, when dummy bar need to enter the dummy bar car, because the preorder operation, the centering of dummy bar may be bad, at this moment the drive unit of the dummy bar centering guider of entrance side driving centering guide holder and guide wheel move, and suitably the enlarged opening degree makes dummy bar can enter smoothly the dummy bar car; At outlet side in order accurately dummy bar to be put in the crystallizer, need to suitably reduce the opening degree of this side dummy bar centering guider, the drive unit that the utility model arranges, when being used in twos, can regulate by drive unit the position of centering guide holder, satisfy flexibly the requirement of different openings degree, and flexible operation is convenient.
As preferably, described drive unit is hydraulic cylinder, and described centering guide holder is fixedly connected with the piston rod of described hydraulic cylinder.Use hydraulic cylinder that the centering guide holder is carried out Adjustment operation, convenient, practical.
As preferably, described centering guide holder bottom is provided with chute, and disposes a slide bar that can be installed on the dummy bar car car body.Guide groove can slide at the guide rod that is fixed on the car body, makes slide bar play the effect of supplemental support to the centering guide holder, so that the utility model is more steady, simple in structure, practical to the guiding process of dummy bar.
As preferably, also comprise a protective cover that can be installed on the dummy bar car car body.This protective cover is installed on the dummy bar car car body for the protection of centering guide holder and guide wheel.
The technique effect that the utility model reaches is as follows: reduced the frictional dissipation to dummy bar, satisfied dummy bar requirement to the different centering opening degrees of dummy bar car in guided procedure, simple in structure, flexible and convenient operation.
Description of drawings
Accompanying drawing 1 is for installing the dummy bar bassinet structure schematic diagram of a kind of dummy bar centering of the utility model guider.
Accompanying drawing 2 is the structural representation of a kind of dummy bar centering of the utility model guider.
Accompanying drawing 3 is the side-looking structural representation of a kind of dummy bar centering of the utility model guider.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail, obviously, described embodiment only is part embodiment of the present utility model.
Embodiment 1:
Referring to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, a kind of dummy bar centering of the utility model guider 5 is installed on the top of dummy bar car car body 1, lay respectively at entrance side and the outlet side of driving-chain 3, a cover be set about every side, jointly to dummy bar transport realize in and the side guiding.The utility model dummy bar centering guider 5 comprises hydraulic cylinder 7, guide wheel 8, centering guide holder 9, locking nut 10, slide bar 11 and protective cover 12.Hydraulic cylinder 7 is fixed on the dummy bar car car body 1, and the perforate in the middle of the centering guide holder 9 is passed in its piston rod 2 ends, and with locking nut 10 that centering guide holder 9 is fixing with piston rod 2, and it can be driven by hydraulic cylinder 7.A guide wheel 8 has been installed at the top of centering guide holder 9, and guide wheel 8 is the free roll that rotates around fixed central spindle, between guide wheel and the mandrel rolling bearing is housed, and makes guide wheel 8 freedom that can go slick.A slide bar 11 is installed on the car body 1, has a semicircle chute 4 in the bottom of centering guide holder 9, this chute 4 can slide at slide bar 11, and slide bar 11 plays the effect of supplemental support centering guide holder 9, makes its guiding more steady.In addition, protective cover 12 is installed also on the car body 1, this protective cover 12 is for the protection of guide wheel 8, centering guide holder 9 and slide bar 11.
When dummy bar 6 need to enter driving-chain 3, because the preorder operation, the centering of dummy bar 6 may be bad, and at this moment hydraulic cylinder 7 driving centering guide holders 9 and the guide wheel 8 of the dummy bar centering guider of entrance side move, suitably the enlarged opening degree makes dummy bar 6 can direct into smoothly on the driving-chain 3; In order accurately dummy bar 6 being put in the crystallizer, suitably to reduce the centering opening degree of dummy bar car by hydraulic cylinder 7 at outlet side, can to finish the guiding to dummy bar.
Should be understood that above-described embodiment only is used for explanation the utility model and is not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
