Detailed description of the invention
Technical scheme in the embodiment of the present invention is understood better in order to make those skilled in the art person, and enable the above-mentioned purpose of the embodiment of the present invention, feature and advantage become apparent more, below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is described in further detail.
Please refer to accompanying drawing 1, accompanying drawing 1 illustrates the structural representation of the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides.Can find out from accompanying drawing 1, the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides comprises: be arranged on the drive unit 7 on the second platform 8 after stove; The guide rope 13 be connected with described drive unit 7; The elevating lever 6 be connected with described guide rope 13; The measuring tube 3 be connected with described elevating lever 6; Described Steel ladle clearance measurement mechanism also comprises the guiding trestle 5 be fixedly installed on after stove on the first platform 4, and the center line of the center line of described guiding trestle 5 and described elevating lever 6 coincides, and described guiding trestle 5 is also provided with scale 16.
Wherein, after stove, the first platform 4 is the operating platform of reinforced, control etc., and after stove, the second platform 8 is the platform of elevating gear for movable fume hood, flue etc., and after stove, after the first platform 4 and stove, the second platform 8 is the device generally used in prior art.Drive unit 7 after being arranged on stove on the second platform 8 is for providing the device of power when this Steel ladle clearance measurement mechanism is measured Steel ladle clearance.Elevating lever 6 is connected with drive unit 7 by guide rope 13, so that during drive unit 7 folding and unfolding guide rope 13, elevating lever 6 can move up and down, thus makes the measuring tube 3 be connected on elevating lever 6 immerse or to propose ladle 2, and then records the numerical value of Steel ladle clearance.Guiding trestle 5 is fixedly installed on a guider after stove on the first platform 4, and this guiding trestle 5 can provide one to lead and the passage of activity, in order to avoid elevating lever 6 arbitrarily rocks during drive unit 7 folding and unfolding guide rope 13 for elevating lever 6.Guiding trestle 5 is provided with the easy-to-read scale 16 with datum line indentation.For making this Steel ladle clearance measurement mechanism obtain measured value accurately by scale 16, the center line of guiding trestle 5 and the center line of elevating lever 6 coincide.
The guiding trestle 5 that the embodiment of the present invention provides can be the shape such as rectangle, channel-shaped, cylindrical shape, as long as one can be provided to lead and the passage of activity, then all in the scope of protection of the invention for elevating lever 6.Same, the present invention does not limit the material of elevating lever 6 and guiding trestle 5 yet.
Further, the two ends of guiding trestle 5 are respectively arranged with guide roller 12 and lower steering roll 11.Elevating lever 6 passes through lower steering roll 11 after penetrating guiding trestle 5 by upper guide roller 12, so just makes the internal activity at guiding trestle 5 that elevating lever 6 is stable, and can not shake.
The Steel ladle clearance measurement mechanism that the embodiment of the present invention provides also comprises fixed block 15, this fixed block 15 is arranged on the inside of elevating lever 6 one end be connected with measuring tube 3, by arranging the mode of fixed block 15, measuring tube 3 can be made firmly to be arranged on elevating lever 6, and can not to drop in molten steel when measuring Steel ladle clearance.
Due to the difference of molten steel composition, the numerical value of required Steel ladle clearance also can not be identical, and thus, the length of required measuring tube 3 is not identical yet, and therefore, measuring tube 3 needs adjustable being arranged on fixed block 15.The sidewall of one end that elevating lever 6 is connected with measuring tube 3 is provided with multiple through hole, and measuring tube 3 can be arranged on fixed block 15 by through hole by fixture 10.When the length variations of the measuring tube 3 needed, measuring tube 3 can be regulated to enter the length of elevating lever 6, and then measure Steel ladle clearance accurately.For ease of the dismounting of fixture 10, preferably, this fixture 10 is screw.
The Steel ladle clearance measurement mechanism that the embodiment of the present invention provides also comprises the leading block 14 be arranged on after stove on the second platform 8, and guide rope 13 is connected with elevating lever 6 by leading block 14.Because drive unit 7 is fixedly installed on after stove on the second platform 8, and elevating lever 6 is vertically place, and therefore, after stove, the second platform 8 is provided with leading block 14 for ease of the activity of guide rope 13 between drive unit 7 and elevating lever 6.Preferably, this guide rope 13 is steel wire rope, this be because steel wire rope is wear-resistant, not fragile, and elastic deformation is little, and what Steel ladle clearance can be made to measure is more accurate.
Please refer to accompanying drawing 2, accompanying drawing 2 illustrates the scheme of installation of the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides.In the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides, for measuring the Steel ladle clearance of ladle 2 from the buggy ladle 1 of track 17 traveling accurately, rapidly, the center line of drive unit 7 and the center line of track 17 vertically spatially should overlap.Preferably, this drive unit 7 is preferably hoist engine.
Please refer to accompanying drawing 2 and accompanying drawing 3, accompanying drawing 3 illustrates the measuring state figure of the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides, wherein, A condition is that measuring tube 3 drops on ladle 2 and wrapped along test mode time upper, B state is the test mode of measuring tube 3 when immersing in the molten steel of ladle 2, and h2 is the length of elevating lever 6, and h3 is edge is wrapped in the bottom of elevating lever 6 distance to ladle 2, h is Steel ladle clearance, and namely in ladle 2, liquid steel level upper surface wraps the distance on edge to ladle 2.
The using method of the Steel ladle clearance measurement mechanism that the embodiment of the present invention provides is: converter 9 is put after steel terminates, buggy ladle 1 is reached the below of Steel ladle clearance measurement mechanism, measuring tube 3 being dropped on ladle 2 wraps along upper, i.e. A condition, the top of now recording guiding trestle 5 is h1 to the distance on elevating lever 6 top.Continue to start buggy ladle 1, until the center line of the central axis of buggy ladle 1 and measuring tube 3 coincides, after the top of the slag in ladle 2 is steady, elevating lever 6 is landed, until the top of elevating lever 6 is concordant with the top of guiding trestle 5, is now B state.After stopping 3-5 second, elevating lever 6 is risen to the first platform 4 after stove, datum line on the bottom of measuring tube 3 and scale 16 is flushed, record measuring tube 3 is h4 by the height of molten steel etch, can draw Steel ladle clearance h=h1-h4 by computing formula h2+h3=(h2-h1)+h3+h+h4.
The numerical value of Steel ladle clearance can be learnt rapidly and accurately by Steel ladle clearance measurement mechanism provided by the invention, and this Steel ladle clearance measurement mechanism have equipment simple, install simple and easy, investment cost is low, the advantage of failure rate is low etc., can be applicable to industrial production.
Above-described embodiment of the present invention, does not form limiting the scope of the present invention.Any amendment done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
