Abstract
The utility model provides a deformation furnace door correction device which comprises a power cylinder. The deformation furnace door correction device is characterized in that one end of the power cylinder is fixed on a supporting base, the other end of the power cylinder is fixed at one end of a pull rod, and the other end of the pull rod is connected with a furnace door. The furnace door can be lifted to the end face of a vertical plate on one side of the supporting base of the deformation furnace door correction device conveniently through a jack, and the furnace door is fixed on the pull rod through bolts and nuts. Meanwhile, through the support of the supporting base, under the drive of the power cylinder, tensile force is formed under the supporting function of the pull rod and the supporting base, one or multiple edges of the deformed furnace door are corrected, straightness is recovered, convenience and labor saving are achieved, no damage can be caused on refractory materials such as refractory fibers on the furnace door, rapid repairing of the furnace door is met completely, high-performance sealing of a heating furnace is guaranteed, and meanwhile maintenance cost is effectively lowered.
Description
Technical field
The utility model relates to a kind of means for correcting, and especially a kind of device that the distortion fire door is proofreaied and correct belongs to maintenance of equipment servicing unit technical field.
Background technology
In the metallurgical industry Rolling Production, need to use various high-temperature heaters that steel are heated, to carry out rolling, the processing and forming of postorder.So charging fire door, the discharging door of heating furnace, not only be in for a long time in hot environment, but also complete continually lifting, rise and fall or the on-off action such as mobile, along with the increase of service time, inevitably can serious thermal deformation occur because of the various factor of productions.In case fire door distortion not only affects the sealing property of heating furnace, cause energy consumption to be multiplied, and in stove, high heat energy escapes, also can impact the auxiliary equipment of periphery and working environment and personal safety, even the scaling loss peripheral equipment, cause serious accident.Must repair the fire door of distortion for this reason.But prior art is to the reparation of fire door complex procedures not only, and careless slightly, will the refractory materials such as refractory fibre on fire door be damaged, and the refractory materials such as refractory fibre of fire door value is 80% of whole fire door value, the refractory materials such as refractory fibre can only disposablely use, in case destroy, whole fire door is namely scrapped, and the manufacturing time of new fire door is approximately about 150 days, and this will have a strong impact on the production of whole piece steel rolling line.In this external repair process, because fire door weight is large, carrying, lifting, fixing comparatively difficulty.Therefore, must be improved prior art, could be satisfied the production of normal heating stove.
Summary of the invention
For producing actual needs, and overcome the fire door that prior art exists and repair difficulty, operation is numerous and diverse, wastes time and energy that it is not enough to wait, and the utility model provides a kind of refractory material such as refractory fibre, high, easy to operate distortion fire door means for correcting of correction glacing flatness of not damaging.
The utility model is completed by following technical proposal: a kind of distortion fire door means for correcting, comprise power cylinder, it is characterized in that power cylinder one end is fixed on the support seat, the other end is fixed on pull bar one end, the pull bar other end is connected with fire door, so that under power cylinder drives, by the supporting role formation pulling force of pull bar with the support seat, the most a plurality of limits alignment of the fire door of distortion.
Described support seat comprises at least two horizontal bases, is located at the riser on each horizontal base, and the stiffener of each horizontal base and riser both sides is located at the interval, is fixed on the crossbeam of riser one side, and fire door is positioned at the opposite side of riser, and is connected with ground jack.
Described pull bar comprises upper and lower two straight-bars arranged side by side, two straight-bar one ends are fixed into one by biside plate, establish connecting plate between biside plate, power cylinder piston rod rod end is fixed on this connecting plate, the power cylinder seat is fixed on support seat crossbeam, and the other end of two straight-bars is connected with upper and lower fixing plate with through hole respectively, establishes bolt and nut in through hole, in order to by bolt and nut, the fire door bottom is connected with fixed head, door upper part is connected with ground jack.
the utlity model has following advantages and effect: adopt such scheme, can be easily by ground jack, fire door be winched to the support seat one cant board end of this device, and be fixed on pull bar by bolt and nut, simultaneously by supportting the support of seat, can be under power cylinder drives, by the supporting role formation pulling force of pull bar with the support seat, finally make one or more limits of the fire door of distortion proofread and correct and recover straight, convenient laborsaving again, and can not cause any damage to the refractory materials such as refractory fibre on fire door, satisfied the quick reparation of fire door fully, guarantee the high-performance sealed of heating furnace, effectively reduce simultaneously maintenance cost.
