The specific embodiment:
Followingly the utility model is elaborated with reference to drawings and Examples:
Shown in Fig. 1～3; a kind of continuous casting of molten steel stopper control transmission device comprises: an end of transverse arm 2 connects stopper 10; the other end connects the top of main shaft 15 with nut 1; outer jointing jacket 12 utilizes key 3 to be installed on the main shaft 15; locking nut 11 is connected with the top of main shaft 15 threadably, and compresses outer jointing jacket 12.Internal protective cover 14 usefulness screws are installed in the upper surface of casing 16; spring 13 is enclosed within on the internal protective cover 14; spring 13 is the compression spring, and its effect is the impulsive force that reduces main shaft 15, and outer jointing jacket 12 is to prevent the influence of the heat of surrounding environment to main shaft 15 with the effect of internal protective cover 14.The middle part of main shaft 15 and bottom are installed two roller set 21 respectively, each roller set 21 is made up of 1 big roller 31 and 1 trundle 32 again, big roller 31 and trundle 32 usefulness roller installing plates 33 are installed on the main shaft 15, and in slideway 4, roll, roller set 21 is formed quadrature with slideway 4 and is contacted support, forms the constraint of main shaft 15 with casing 16 relative positions.Slideway 4 usefulness screws 27 are connected with casing 16.Roller set 21 is the stability in order to guarantee that main shaft 15 moves vertically.
The course of work of a kind of continuous casting of molten steel stopper control of the utility model transmission device can be divided manually and automatic two kinds of operation sequences: when manual operation, at first stopper being controlled transmission device is fixed on the tundish wall, selected good operating position, when needs reduce or block the tundish tapping hole, hand bar 8 is upwards carried, and by the engagement of bevel gear 9, tooth bar 18, main shaft 15 moves down, its displacement can reach 160 millimeters, by pointer 20 indications.Drive stopper 10 by transverse arm 2 and move down this moment, and the tundish tapping hole reduces or blocks.When needs enlarged the tundish tapping hole, to pressing down, by the engagement of bevel gear 9, tooth bar 18, main shaft 15 moved up and drives stopper 10 and moves up with hand bar 8, and the tundish tapping hole increases, and molten steel can inject crystallizer and begin continuous casting.When needs alter operation position, with hand bar 8 left or right rotation, by the engagement of bevel gear 9, tooth bar 18, can be in any positions rotation of 105 degree of the center line of main shaft 15.When automatic operation, electronic cylinder passes through upper bracket 22 and outer jointing jacket 12, drives main shaft 15 upper and lower moving, and drives stoppers 10 upper and lower moving by transverse arm 2, and realization tundish tapping hole enlarges or reduces.
The utility model is simple in structure, the control of rolling supporting construction is light flexibly, make stopper accurate positioning, stable, adapt to the operation of diverse location, under the steel-making continuous casting adverse circumstances, can work steadily in the long term, can be widely used in the continuous casting of molten steel production in the metallurgical industry.
