Description
Technical field
The present invention relates to a kind of sliding frame and spin upside down formula door type structure steel ladle gate mechanism, belong to steel-making machinery, especially a kind of Slide gate mechanism of steel ladle be arranged on bottom steel ladle.
Background technology
In current known Slide gate mechanism of steel ladle, mainly contain two kinds of structure types, one is left and right opening door formula door type structure slide gate mechanism; Another kind is that sliding frame spins upside down formula door type structure slide gate mechanism; The security of left and right opening door formula door type structure slide gate mechanism is relatively high, but due to its complex structure, complex operation, difficult in maintenance, cost is higher, in the application of medium and small steel ladle market, be subject to larger restriction; Sliding frame spins upside down formula door type structure slide gate mechanism, and structure is simple, easy to operate, maintenance is simple, cost is lower, obtains applying comparatively widely in medium and small ladle market.
Spin upside down in formula door type structure slide gate mechanism at sliding frame, have two kinds of versions at present, one is arranged on sliding frame by pressure roller, and fixed rack is arranged on underframe; Another kind is arranged on underframe by pressure roller, is arranged on sliding frame by slip slide rail; By the rolling of roller on slide rail (or slide rail slides on roller), realize the relative motion of sliding frame and underframe in slide gate mechanism.
There is common defect in the slide gate mechanism of these two kinds of versions: because the locking pressure between upper slide and lower skateboard is that the slide rail (or roller) slided on underframe by the roller of sliding frame (or slide rail) produces afterwards, in the whole course of work, pressure is along with the corresponding fluctuation of mobile appearance of sliding frame, its power transmission point is the contact of line face and constantly change, cause the fluctuation of pressure between slide plate, the safety coefficient of such slide gate mechanism reduces, there is very big potential safety hazard, easily cause production accident; In steel pouring process, roller is easily adhered to by slag, and high temperature is yielding, can not rotary rolling, and roller shaft is easy to wearing and tearing, and cleaning is safeguarded very difficult, easily causes and locks pressure oscillation between upper slide and lower skateboard and produce bleed-out phenomenon; There is roller shaft phenomenon of rupture time serious, great pernicious production accident and security incident can be caused.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Slide gate mechanism of steel ladle, realize locking pressure between upper slide and lower skateboard not fluctuate with the movement of sliding frame, locking pressure stability is even, and slide plate slides is steady, reduces the generation of production accident dramatically.
For realizing above-mentioned technique effect, a kind of Slide gate mechanism of steel ladle of the present invention, 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, in the left and right sides of underframe, the fixed rack suitable with slip slide rail is set, 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 to be arranged in upper frame and to contact with upper slide, the lower mouth of a river is arranged on below lower skateboard, described drive unit is arranged on upper and lower frames top, and it is connected with sliding frame, and drive unit shifts sliding frame onto the end, sliding frame turning cylinder is fallen in underframe rotating shaft base automatically, and 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, move back and forth together with now sliding frame slip slide rail fits tightly with underframe fixed rack, spring pressure is evenly passed to upper slide and lower skateboard, two pieces of 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 Slide gate mechanism of steel ladle also comprises spring attachment, in the underframe left and right sides, symmetry offers spring housing, spring attachment is arranged in spring housing, described spring attachment comprises spring, spring bearer plate, hexagon slotted nut and split pin, all bolt hole is offered in spring housing and spring bearer plate correspondence position, 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, compress adhesive force between upper frame and underframe 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, avoiding the impact artificially adjusting operation factors, ensureing to compress adhesive force between upper frame and underframe more reliable and more stable.
Described a kind of Slide gate mechanism of steel ladle also comprises slide plate hold down gag and lower 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 two pieces of slide plate close contacts slide, and avoid the generation of bleed-out phenomenon between slide plate.
In steel ladle steel pouring process, sliding frame is back and forth stable in underframe to be slided, 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 reduces the bleed-out phenomenon between slide plate.
Structure of the present invention is simple, easy to operate, under the prerequisite of low cost, formula door type structure steel ladle gate mechanism is spun upside down for sliding frame, achieve and lock pressure between upper slide and lower skateboard and do not fluctuate with the movement of sliding frame, locking pressure stability is even, slide plate slides is steady, decreases the generation of production accident dramatically.
