The technical scheme that the utility model solves the problems of the technologies described above is: a kind of pans Stopper opening and closing mechanism, this mechanism's housing is fixed on the processing plane of pans, and electric digital cylinder or hydraulic cylinder are installed on the hold-down support and mobile support saddle of pans mechanism for opening/closing; Stopper and crossbeam, crossbeam and elevating lever and mobile support saddle link together by bolt and alignment pin; Manual joystick and linkage pin joint together, connecting rod promotes moving up and down of elevating lever; Manual joystick is fixed on the rotary box by sliding bearing; Rotary box couples together by thrust bearing and this mechanism's housing; Linear bearing is fixedly mounted on the inner walls, and elevating lever is loaded in two linear bearings; Anti-rotation lock is provided with a pair of fixed guide bearing, and a pair of guide bearing of adjusting offset, and working face is sealed; Elevating lever processing gathering sill; Possesses positioning function, elevating lever lifting in the impulse stroke scope.
Described stopper and crossbeam one end are fixed together, and the crossbeam other end and elevating lever are fixed, and fix in another position and mobile support saddle simultaneously, have alignment pin to link together between elevating lever and mobile support saddle, can not produce relative motion, and the stopper location accurately.
Described hold-down support and mobile support saddle possess fast interface, and electric digital cylinder or hydraulic cylinder can fast assembling-disassemblings, save and water steel time.
Described elevating lever moves up and down by the linear bearing guiding that is installed in housing, and lifting is steady, can realize the action of little displacement, no end play, and reflection is sensitive.
The lifting in the impulse stroke scope of described elevating lever has the high and low position of the limit.After rising to peak, linkage is elongated to extreme position, is limited in the high point of limit position; After elevating lever dropped to lowest order, mobile support saddle contacted with housing, was limited in limit low spot position.
Described manual joystick and linkage pin joint are moved manual joystick up and down together, drive elevating lever and move up and down.
Described manual joystick is fixed on the rotary box by axle and sliding bearing, and the rotation manual control stick can make rotary box and linkage along the rotation of elevating lever axis, and connecting rod and elevating lever can relatively rotate by oscillating bearing.
The rotation of elevating lever was adopted guide bearing when described anti-rotation lock prevented rotary box and manual joystick rotation in the gathering sill of elevating lever, can be by adjusting eccentric shaft offset compensate for wear amount.
Described anti-rotation lock is installed on the housing, uses sealing gasket protection working face.
The utlity model has following advantage:
When liquid level fluctuation of crystallizer, automatic control system promotes hydraulic cylinder or the action of electric digital cylinder, elongate or shorten shaft, drive the lifter rod lifting that leads by linear bearing by mobile support saddle, drive crossbeam and stopper lifting, stopper is gradually opened or is goed deep into middle pot drainage opening, reach the adjusting mouth of a river aperture, close and open middle pot drainage opening, thereby control stably remains on the predetermined height molten steel surface in the crystallizer from the molten steel flow of pans injection crystallizer.
Opening in continuous casting production watered and when handling unexpected accident, manual control pans Stopper opening and closing mechanism moves manual joystick up and down, drives elevating lever and moves up and down.Manual joystick also can rotate arbitrarily by 360 degree, anti-rotation lock is provided with a pair of fixed guide bearing, and a pair of guide bearing of adjusting offset, adopts eccentric shaft to adjust wear extent, rolling bearing leads on elevating lever and prevents to reverse, simultaneously the working face good seal.
