The straight quick cone adjusting structure of the narrow parapodum roller of arc conticaster crystallizer
Technical field
The utility model relates to straight arc conticaster crystallizer field of components, refers to particularly the quick cone adjusting structure of the narrow parapodum roller of a kind of straight arc conticaster crystallizer.
Background technology
Straight arc formula continuous casting refers to that casting in plumbness carries out, and before strand does not all solidify, in vertical state, after all solidifying, does not enter the curved system of rectifying, a kind of steel type of watering continuously that 90-degree bent is the level of state and exports.Advantage is that slab cooling is even, and in molten steel, a large amount of field trashes have floating chance at crystallizer, and residual field trash distributes and do not produce local accumulation phenomenon in strand.Conticaster crystallizer is to determine one of slab quality, casting speed, the most important link of conticaster operating rate.Narrow side copper plate is the mould for cooling molten steel in conticaster crystallizer, continuous casting billet be by crystallizer by molten steel is cooling in copper plate of crystallizer, be shaped after, straightening becomes up-to-standard strand continuously, therefore in conticaster, will adopt in a large number straight arc conventional slab caster casting steel billet.
It is the back draught of adjusting copper coin surface and sufficient roll surface for measuring that the sufficient roller of narrow side copper plate connects arc special ruler, and in normally using on production line, there are wearing and tearing on copper coin surface, and copper coin often need be removed rear processing wear surface increases coating again.Therefore copper coin is used rear thickness often to change, if more renewed, repair the just necessary back draught size of adjusting sufficient roller and copper coin surface of narrow side copper plate, because copper coin is installed former design and can not be adjusted, so must connect arc special ruler by narrow side copper plate foot roller in crystallizer reparation, measure the back draught of adjusting copper coin surface and sufficient roll surface; The straight narrow parapodum roller of arc crystallizer is heavily 30kg rectangular body, is arranged on the below of narrow side copper plate water tank, and one group of 4 sufficient roller amounts to 8 narrow parapodum rollers.In online production, the narrow side copper plate of crystallizer, sufficient roller belong to wearing detail.And the tapering adjustment of narrow parapodum roller is all for adjusting foundation according to narrow side copper plate surface size, therefore after changing narrow side copper plate or change narrow parapodum roller, must adjust the tapering of narrow parapodum roller group, if it is inaccurate that the tapering of narrow parapodum roller group is adjusted, after upper machine, the narrow side bulge of the lighter's strand is changed lower machine affect rhythm of production, serious quality equipment breakdown that severe one causes that bleed-out, corner are split etc.The tapering of the narrow parapodum roller of straight arc crystallizer of traditional design is adjusted into plus-minus gasket type method of adjustment, therefore before, when adjusting narrow parapodum roller tapering, first measure once, according to measurement data, the sufficient roller of heavily about 30kg is pulled down afterwards, pad adds deduct, tighten again afterwards, measure again, so repeatedly until adjust accurately, because crystallizer is placed on the stand of liftoff 2 meters, therefore the up-and-down dismounting of narrow parapodum roller that needs a people ceaselessly lifting 30kg, so repeatedly tax one's mind and strength, and very dangerous, two groups narrow parapodum rollers of each adjustment need 2 people just can complete for 8 hours, annual accumulative total needs 896 hours manually.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will overcome the narrow parapodum roller of the straight arc crystallizer cone adjusting degree of complicated above-mentioned complexity, provide a kind of efficiently, the straight quick cone adjusting structure of the narrow parapodum roller of arc conticaster crystallizer efficiently.
For achieving the above object, the quick cone adjusting structure of the narrow parapodum roller of straight arc conticaster crystallizer that the utility model is designed, comprise the bracing frame that is arranged on the narrow side copper plate water tank of crystallizer below, support frame as described above is provided with the shoulder hole that left and right is run through, on the hole inwall of described shoulder hole one side, be provided with thread segment, sufficient roller frame is installed on support frame as described above one sidewall, described sufficient roller frame bottom is provided with adjusting device, described adjusting device is fixed on bracing frame through shoulder hole, it is characterized in that:
Described adjusting device comprises the screw rod that is fixedly connected with hanging on sufficient roller frame with cap head, the described screw rod end that is fixedly connected with is provided with thread segment, be fixedly connected with cover on screw rod and have cored screw and locking nut, described cored screw outside is provided with thread segment and is connected with shoulder hole inner thread section, described cored screw thread segment place also coordinates is equipped with hold-down nut, described hold-down nut is fixed on cored screw on bracing frame, described locking nut is positioned at and is fixedly connected with screw flight section place, in order to connecting screw rod and the cored screw of being locked.
Further, described being fixedly connected with is also set with dish spring bag and setscrew nut on screw rod, seam butt on one end of described dish spring bag and sufficient roller frame, a side butt, the opposite side of described setscrew nut and the cored screw butt of the other end of described dish spring bag and setscrew nut.
Further, described dish spring bag arranged outside has sealing shroud, to wrap up dish spring bag.
Again further, described setscrew nut one end is provided with annular boss, in order to fit with shoulder hole sidewall.
Again further, between described sealing shroud and shoulder hole, be provided with sealing ring, avoid molten iron and impurity to flow in shoulder hole.
Again further, described in, being fixedly connected with screw rod upper locking nut outside also overlaps and has reinforcing nut.
The utility model has the advantage of: design cored screw, can in the situation that not unloading sufficient roller, regulate the tapering of sufficient roller, reduce manpower and materials, reduced labour intensity, improve operating efficiency, saved the production time, can reduce the generation of the security incident in series installation process simultaneously.
