Background technology
as everyone knows, lift resistance furnace is mainly used for the high temperature sintering of diamond bit, emery grinding wheel binder, accurate grinding materials and grinding tool, powder metallurgy, various structural ceramics etc.Early stage lift resistance furnace, it is usually by burner hearth, liftable furnace bottom cover with drive the lift drive mechanism of furnace bottom cover activity jointly to form, but its defect existed is: furnace bottom cover to be remained with the grate of lower furnace portion by lift drive mechanism and is connected, not individual member, its workman is when actual job, need by material by by cart transport to stove, then unload and be carried on furnace bottom cover, comparatively loaded down with trivial details time-consuming.
certainly in a known and common at present class lift resistance furnace, furnace bottom cover is designed to independently component, and pushes by dolly; Lift drive mechanism is then generally the elevating bracket of singe screw or rack drives, and this elevating bracket is usually designed to the form of single-open, can depart from dolly and lifting by furnace bottom cover from a direction fork.Compare traditional lift resistance furnace, really save man-hour, but still there is following defect when reality uses:
1) because lift drive mechanism is that one-sided lifting drives, elevating bracket often discontinuity equalization in the process of fork kindling bottom, causes furnace bottom cover to tilt, thus cannot effectively and to close with burner hearth bottom uncovered coupling completely reliably.Cause body of heater not close time serious and SINTERING PRODUCTION, greatly reduce production efficiency.
2) for want of dolly to be implemented effectively and position-limit mechanism reliably, makes dolly often depart from burner hearth lower position, after needing workman to adjust can with burner hearth bottom open position Corresponding matching, comparatively loaded down with trivial details, comparatively affect production efficiency.
Summary of the invention
the utility model object is: provide a kind of furnace bottom cover up and down balance system reliable lift resistance furnace, and this resistance furnace fast and effeciently can guarantee furnace bottom cover and burner hearth bottom uncovered mating well, thus enhances productivity.
the technical solution of the utility model is: a kind of lift resistance furnace, comprise the furnace shell be fixed on support, the burner hearth be fixed in furnace shell, with the uncovered furnace bottom cover that coordinates of burner hearth bottom be positioned at below burner hearth for transporting the dolly of furnace bottom cover; Characterized by further comprising the hoistable platform for carrying dolly and the steel wire rope synchronization lifting drive unit for driving described hoistable platform to be elevated, described steel wire rope synchronization lifting drive unit comprises the motor and reduction box, the bull wheel be located on reduction gearbox output shaft that are fixed on described support side, and pivotable to be installed on bottom furnace shell and around at least three sheaves of the uncovered distribution that is centrosymmetric of burner hearth bottom, the steel wire rope on described bull wheel is fixed through described sheave is vertical with hoistable platform.
further, the quantity of bull wheel described in the utility model is two, is individually fixed in the two ends of described reduction gearbox output shaft; And the quantity of described sheave be four and in four directions distribution, these four sheaves be divided into two groups corresponding with two bull wheels respectively; Often group is two sheaves and is arranged on straight line with corresponding bull wheel, bull wheel is drawn two steel wire ropes respectively through fixing with two sheaves organized are vertical with hoistable platform.
further, the dolly position-limit mechanism be located at for the activity of block dolly on hoistable platform is also comprised in the utility model, this dolly position-limit mechanism comprises car front locking mechanism and car backstop locking mechanism, described car front locking mechanism comprise at least one front elasticity be installed on hoistable platform turn over block and for block its upset before spiral cover; Car backstop locking mechanism then comprises at least one rear elasticity be installed on hoistable platform and turns over block and the rear spiral cover for its upset of block; When described forward and backward spiral cover is outwarded winding, described forward and backward elasticity is turned over block and is all overturn towards dolly and be butted on dolly.
more preferred, hoistable platform described in the utility model is provided with the groove turning over block for burying forward and backward elasticity underground.
more preferred, dolly described in the utility model comprises vehicle frame and pivotable and is mounted to the forward and backward wheel shaft being respectively used to fixing front and rear wheel on vehicle frame, when described forward and backward spiral cover is outwarded winding, described forward and backward elasticity is turned over block and is overturn respectively and be butted on forward and backward wheel shaft.
