Description
Technical field
The utility model relates to a kind of field of steel metallurgy, is specifically related to a kind of crystallizer locking cylinder disc spring pick-up unit.
Background technology
In steel plant's steelmaking system, the main application of crystallizer provides even to molten steel exactly and cools fast, impels molten steel quick solidification, base shell homoepitaxial.The steel passage excessively of crystallizer is the rectangle frame be made up of two groups of copper coins varied in size, and molten steel is cooling forming when by passing through in rectangle frame.And be strained by locking cylinder between the copper coin that in rectangle frame, a packet size is larger, if the disc spring pulling force in locking cylinder is once deficiency, just gap is there will be between rectangle frame, and molten steel just can penetrate in gap in the process passed through, and hard thrust will be formed at rectangle frame seam crossing after these molten steel cools penetrating in gap, damage will be caused to the steel billet just formed, molten steel is being that surface crystallization defines box hat by time in rectangle frame, its inner or molten steel, once after the box hat of billet surface scratched by these thrusts, inner molten steel will flow out, there is bleed-out phenomenon.Described each crystallizer, when safeguarding, must detect locking cylinder, guarantees that the pulling force of the disc spring of its inside is working properly.And at present when the detection to disc spring, all that oil cylinder is dismantled, by independent after the dismounting of the disc spring of its inside, disc spring is extruded, observe its recovery capability to judge that whether disc spring is normal, its workload is large, and the time of detection is long, and efficiency is low, easily judge by accident simultaneously, extreme influence is caused to production.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of structure simple, easy to use, workload is little, short for detection time to crystallizer locking cylinder disc spring, testing result is crystallizer locking cylinder disc spring pick-up unit accurately.
In order to solve the problems of the technologies described above, the utility model have employed following technical scheme:
A kind of crystallizer locking cylinder disc spring pick-up unit, comprise worktable and vertically arrange on the table and fixed head I arranged in parallel and fixed head II, the installation position for laying locking cylinder is formed between fixed head I and fixed head II, described fixed head I top is provided with to downward-extension and groove I for embedding locking cylinder secondary piston bar, described fixed head I is also provided with the perforate for exposing for locking cylinder front end pouring orifice, described fixed head II top is provided with to downward-extension and groove II for embedding locking cylinder back piston bar, the degree of depth of described groove I and described groove II is less than the height of described fixed head I and described fixed head II respectively, on described fixed head II, level is provided with and passes the rotating shaft of described fixed head II, rotating shaft is combined with the push pedal for promoting locking cylinder towards installation position threaded one end, the described worktable being arranged in described installation position is provided with the gathering sill being parallel to described rotating shaft, the orienting lug be slidably matched with described gathering sill is provided with bottom described push pedal, the described rotating shaft being positioned at described fixed head II two ends is provided with the baffle ring moved axially for limiting described rotating shaft, described fixed head I is provided with electric pushrod back to level on the described worktable of side, described installation position, the top of electric pushrod comprises and to be oppositely arranged with locking cylinder secondary piston bar and can towards the flexible expansion link of locking cylinder secondary piston bar, the top of described expansion link is provided with the pressure-detecting device for detecting oil cylinder secondary piston bar thrust size.
In the utility model, locking cylinder is placed on the installation position between fixed head I and fixed head II, wherein the front and back piston rod of locking cylinder is embedded in groove I and groove II respectively, and the pouring orifice of locking cylinder front end is then expose from fixed head II upper shed, is convenient to inject hydraulic oil.After locking cylinder places, rotate the rotating shaft on fixed head II, and it is positioned at push pedal that installation position threaded one end coordinates under the effect of gathering sill and orienting lug, make push pedal promote locking cylinder to fixed head I direction to make it to be pressed on fixed head I, start electric pushrod, make the pressure-detecting device of expansion link front end and the plunger rod contacts of locking cylinder front end, but do not produce any pressure.Pouring orifice now to locking cylinder injects certain hydraulic oil, piston is under the effect of hydraulic oil, while compression disc spring, the back piston bar of the oil cylinder other end moves backward, record locking cylinder back piston bar mobile displacement, then electric pushrod is restarted, the pressure-detecting device of expansion link front end is made to move the displacement identical with the piston rod of locking cylinder rear end to locking cylinder one end, then stop injecting hydraulic oil in locking cylinder, now, piston in locking cylinder forward end under the effect of disc spring moves, because the secondary piston bar of locking cylinder front end is blocked by the pressure-detecting device on expansion link, will extrude pressure-detecting device, because the extruding force of secondary piston pole pair pressure-detecting device derives from the spring force of disc spring, so it is exactly the spring force of disc spring that pressure-detecting device measures what come, then the numerical value of disc spring spring force in locking cylinder brand-new to the numerical value and of testing the disc spring spring force obtained is compared, whether judgement is obtained a result qualified.Relative to traditional detection method, no longer need to dismantle locking cylinder, reduce workload, shorten locking cylinder disc spring detection time, improve detection efficiency, also improve the accuracy detected locking cylinder disc spring, structure of the detecting device is simple in addition simultaneously, use operation also to facilitate, alleviate the work load of operator.
As optimization, described fixed head II is provided with the drive motor for driving described rotating shaft to rotate back to the described worktable of side, described installation position.Utilize motor to control the rotation of rotating shaft, improve mechanization degree, alleviate the work load having drawn operator further.
As optimization, described rotating shaft is provided with bearing and described fixed head II is rotatably assorted.Make axis of rotation more flexible, also reduce wearing and tearing each other simultaneously, improve serviceable life.
As optimization, described electric pushrod is provided with the displacement transducer I for detecting described pressure-detecting device displacement, and described fixed head II is provided with the displacement transducer II for detecting oil cylinder rear end piston rod displacement.Improve the precision of measurement, it is more accurate to make the detection of locking cylinder.
In sum, the beneficial effects of the utility model are: the utility model structure is simple, use easy to operate, only need locking cylinder to be placed on the installation position between fixed head I and fixed head II, after passing into hydraulic oil, then operation electric pushrod and drive motor can complete the detection to locking cylinder disc spring respectively, reduce workload, improve crystallizer locking cylinder disc spring detection time and detection efficiency, also improve the accuracy of detection simultaneously.
