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 steel ladle slide gate mechanism that is arranged on the steel ladle bottom.
Background technology
In present known steel ladle slide gate mechanism, mainly contain two kinds of structure types, a kind of 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, is subject to larger restriction in medium and small steel ladle market application; Sliding frame spins upside down formula door type structure slide gate mechanism, simple in structure, easy to operate, safeguard simple, cost is lower, obtain applying comparatively widely in medium and small ladle market.
Spin upside down in formula door type structure slide gate mechanism at sliding frame, two kinds of versions are arranged at present, a kind of is that pressure roller is arranged on sliding frame, and fixed rack is arranged on underframe; Another kind is that pressure roller is arranged on underframe, and the slip slide rail is arranged on sliding frame; , the rolling on slide rail (or slide rail slides on roller), realize the relative motion of sliding frame and underframe in slide gate mechanism by roller.
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 to produce after roller (or slide rail) by sliding frame slides into slide rail (or roller) on underframe, pressure is along with mobile appearance of sliding frame fluctuates accordingly in the whole course of work, its power transmission point is the contact of line face and constantly variation, cause the fluctuation of pressure between slide plate, the safety coefficient of slide gate mechanism reduces like this, 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 locking pressure oscillation between upper slide and lower skateboard and produces the bleed-out phenomenon; The roller shaft phenomenon of rupture occurs when serious, can cause great pernicious production accident and security incident.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of steel ladle slide gate mechanism, realize that between upper slide and lower skateboard, locking pressure does not fluctuate with the movement of sliding frame, the locking pressure stability is even, and slide plate slides is steady, reduces dramatically the generation of production accident.
for realizing above-mentioned technique effect, a kind of steel ladle slide gate mechanism of the present invention, it comprises upper frame, underframe, sliding frame, the 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, the sliding frame both sides arrange the slip slide rail, the left and right sides at underframe arranges the fixed rack suitable with the slip slide rail, the sliding frame bottom arranges turning cylinder, at the 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 with upper slide, contacts, the lower mouth of a river is arranged on the lower skateboard below, described drive unit is arranged on the upper and lower frames top of the trellis, it is connected with sliding frame, drive unit is shifted sliding frame onto the end, the sliding frame turning cylinder is fallen in the underframe rotating shaft base automatically, sliding frame relies on the gravity automatic turning until with underframe, contact, the sliding frame upset is lifted until with the upper frame upper slide, contact, drive unit makes sliding frame up, complete the Self-pressurizing agri process, sliding frame slip slide rail and underframe fixed rack fitted tightly together and moved back and forth this moment, 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, symmetry is offered spring housing in the underframe left and right sides, spring attachment is arranged in spring housing, described spring attachment comprises spring, spring bearer plate, hexagon slotted nut and split pin, all offer bolt hole in spring housing and spring bearer plate correspondence position, square head bolt passes bolt hole, hexagon slotted nut screws square head bolt, split pin is passed hex nut and is fixed, 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 the 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 between upper frame and underframe to compress adhesive force more reliable and more stable.
Described a kind of steel ladle slide gate mechanism 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, guarantee that further two slide plate close contacts slide, avoid the generation of bleed-out phenomenon between slide plate.
In the steel ladle steel pouring process, sliding frame is back and forth stablized and is slided in underframe, the 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 present invention is simple in structure, easy to operate, under prerequisite cheaply, spin upside down formula door type structure steel ladle gate mechanism for sliding frame, realized that between upper slide and lower skateboard, locking pressure does not fluctuate with the movement of sliding frame, the locking pressure stability is even, slide plate slides is steady, has reduced dramatically the generation of production accident.
