For realizing above-mentioned technique effect, a kind of steel ladle slide gate mechanism of the utility model, it comprises upper frame, underframe, sliding frame, slip slide rail, fixed rack, upper slide, lower skateboard, filling pipe end, the lower mouth of a river, turning cylinder, rotating shaft base, square head bolt and drive unit, described upper frame is connected by square head bolt with underframe, sliding frame both sides arrange slip slide rail, the left and right sides at underframe arranges the fixed rack suitable with slip slide rail, sliding frame bottom arranges turning cylinder, at underframe correspondence position, the rotating shaft base suitable with turning cylinder is set, upper slide is arranged in upper frame, lower skateboard is arranged in sliding frame, filling pipe end is arranged in upper frame and contacts with upper slide, the lower mouth of a river is arranged on lower skateboard below, described drive unit is arranged on upper and lower frames top of the trellis, it is connected with sliding frame, drive unit is shifted sliding frame onto the end, sliding frame turning cylinder is fallen in underframe rotating shaft base automatically, sliding frame relies on gravity automatic turning until contact with underframe, sliding frame upset is lifted until contact with upper frame upper slide, drive unit makes sliding frame up, complete Self-pressurizing agri process, together with fitting tightly with underframe fixed rack, now sliding frame slip slide rail also moves back and forth, spring pressure is evenly passed to upper slide and lower skateboard, two slide plate close contacts are slided and without bleed-out phenomenon between slide plate, and complete pouring molten steel throttling process.
Described a kind of steel ladle slide gate mechanism also comprises spring attachment, in the underframe left and right sides, symmetry is offered spring housing, spring attachment is arranged in spring housing, described spring attachment comprises spring, spring bearer plate, hexagon slotted nut and split pin, in spring housing and spring bearer plate correspondence position, all offer bolt hole, square head bolt is through bolt hole, hexagon slotted nut screws square head bolt, split pin is fixed through hex nut, make upper frame, underframe, spring, spring bearer plate links together, slide gate mechanism is when depressurization phase, between upper frame and underframe, compress adhesive force and keep stable.
Described square head bolt arranges spring bearer plate limited step, the bolt hole position of spring bearer plate offers cannelure, when adjusting upper frame and underframe position, avoid the impact of artificial adjusting operation factor, guarantee to compress adhesive force between upper frame and underframe more reliable and more stable.
Described a kind of steel ladle slide gate mechanism also comprises slide plate hold down gag He Xia mouth of a river top-fastener, described slide plate hold down gag is fixedly installed in upper frame, fits and compress upper slide, it is outside that lower mouth of a river top-fastener is arranged on the lower mouth of a river, hold out against the lower mouth of a river, further guarantee that two slide plate close contacts slide, avoid the generation of bleed-out phenomenon between slide plate.
In steel ladle steel pouring process, sliding frame is back and forth stablized and is slided in underframe, and slip slide rail contacts with fixed rack, and spring pressure is passed to upper slide and lower skateboard uniformly and stably, between slide plate, pressure oscillation is little, effectively reduced the bleed-out phenomenon between slide plate.
The utility model is simple in structure, easy to operate, under prerequisite cheaply, for sliding frame, spin upside down formula door type structure steel ladle gate mechanism, realized and between upper slide and lower skateboard, locked pressure and with the movement of sliding frame, do not fluctuate, locking pressure stability is even, slide plate slides is steady, has reduced dramatically the generation of production accident.
