Description
Technical field
The utility model relates to a kind of retaining mechanism, relates in particular to a kind of clad retaining mechanism, is applicable to iron and steel enterprise and other corresponding industrial circle.
Background technology
In process for making, liquid steel temperature is perplexing production and the quality of steel-making for a long time as important steel-making logistics progress index and technological parameter.In the steel-making reaction vessel relevant with temperature, ladle is moving range maximum, hold the longest one of steel time, is also the container that temperature is had the greatest impact undoubtedly.Constantly promote for the measure that reduces ladle temperature drop for a long time, the technical measures of ladle stamp as one wherein also in continuous improvement.
In the time considering steel ladle full stroke covering technique, the technology arrangement of hot repair and operation are proposed to new requirement.Ladle generally designs clad steady pin in the little hook pin of ladle deslagging side in the time of automatic covering design.When ladle-pot hot-repair tumble arrangement technology required direction and deslagging opposite direction, in the process of tumbling, fixing on ladle of clad just becomes the key problem that needs solve.
Solving clad in the basic prerequisite following 1 of ladle-pot hot-repair tipping table) the hot repair clad fixed mechanism of tumbling need to be arranged on tipple, can increase workload and the scrap build expense of all ladles transformations otherwise fixed mechanism is set on ladle; 2) the hot repair clad fixed form in process of tumbling requires to adopt automated manner, and mechanical, hand-driven mode can increase workman's labour intensity greatly, and the development of modern steel works equipment will more be adopted in an automated fashion; 3) ladle-pot hot-repair is tumbled in process needs to keep clad reliably to locate.If the position of ladle clad is uncertain, the complexity of mechanism design will be increased.Therefore,, for the technical problem existing in prior art, a kind of new retaining mechanism of exigence solves above-mentioned technical problem.
Summary of the invention
The utility model is just for the technical problem existing in prior art, a kind of simple in structure, easy to operate clad retaining mechanism is provided, that the ladle tipping table ladle retaining mechanism of the utility model design has been realized is reliable, safe, practical, keep in repair target easily, while giving in each steel mill steel ladle full stroke covering, consider that the realization that hot repair is tumbled provides reference and reference, and have very strong application value realistic.
To achieve these goals, the technical solution of the utility model is as follows, a kind of clad retaining mechanism, it is characterized in that, described retaining mechanism comprises ladle, is arranged on the clad on ladle, and the top of corresponding ladle trunnion case arranges two locking gudgeons outside described clad, two locking gudgeons, coaxially through clad center, are arranged on the both sides of clad; Described retaining mechanism also comprises the framework of tumbling that is arranged on bottom, described in tumble on framework and be provided with four connecting bar locking mechanisms.
As a kind of improvement of the present utility model, described four connecting bar locking mechanisms comprise locking arm, connecting rod, driving fork and Electrohydraulic push rod, and described driving fork connects locking arm, and described Electrohydraulic push rod connects connecting rod, and promotes link motion.Locking arm contacts with the locking gudgeon designing on clad realizes locking.For accurate clad locking jaw arm, this four connecting bar lockings mechanism adopts electric drive hydraulic thruster to drive, and by adopting limit signal sender, stops fluid driven power source, and Electrohydraulic push rod uses the stroke of hydraulic lock mode fixed drive hydraulic cylinder, and then accurate positioning and locking claw hook.
This technical scheme has overcome the problem that in prior art, retaining mechanism lock-bit precision is not high, air cylinder driven strength is inadequate.
As a kind of improvement of the present utility model, described locking arm is set to rigid jaw hook structure.The shape design of this locking claw hook changes and adapts with the location of clad, and locking arm is locking pin and from locking state smooth opening on hook smoothly.Therefore, this locking bail and the locking pin tactile part that is coupling is not regular circular arc, but the combination of several sections of discontinuous circular arcs, the location that can adapt to bearing pin changes, and locks freely and throws off, and arranges after the enough structures of pawl, and overall structure is simple, and troubleshooting is convenient.
As a kind of improvement of the present utility model, described in tumble on framework and be also provided with positioning vertical column.Because the thickness of steel slag that wraps edge in ladle actual moving process changes, the location of clad on ladle also changes.In the accurate location of ladle, be convenient to the location of locking arm in order to ensure the ladle-pot hot-repair clad on framework of tumbling, this scheme has designed clad positioning vertical column on framework tumbling, and contacts with the clad holder point of the opposite one side clad design of hanging pin at clad.
1), whole apparatus structure is simple with respect to prior art, the beneficial effects of the utility model are as follows:, cost is low; Easy to operate, reliable, quick; 2) this scheme adopts the form of locking claw hook to realize locking, and implementation is simple, and troubleshooting is convenient; 3) retaining mechanism adopts four connecting rod modes, has reduced driving power; 4) clad location adopts in seat packet procedures the mode of location automatically, need not design driven, and simple in structure.
