Description

High temperature rotating elevating mechanism
Technical field
The present invention relates to a kind of elevating mechanism, and in particular to one kind has single power source driving lifting, provided with transmission device And the controllable high temperature rotating elevating mechanism of lifting regional temperature and its application in heat-treatment furnace.
Background technology
Elevating mechanism be it is a kind of be widely used in industrial production can on vertically passage carrying people or goods machinery Device.The elevating mechanism of current existing type is generally included:Fork type elevator, guide rail chain-type lift, cable wire Formula lifting device, screw rod lifting device, wherein, fork type elevator is commonly used to because overall structure weight is big, size big Used under engineering construction or industrial environment, it is higher using threshold, it is more difficult to popularize.In addition, existing guide rail chain-type lift, Cable type lifting device, screw rod lifting device are typically all realized above and below object by bi-motor or multi-motor driving hoisting mechanism Lifting.Although the driving force of the elevating mechanism output of this multi-motor driving is larger, its subject matter existed is:When it In motor when breaking down, and other motor is still in work, therefore will necessarily produce hoistable platform Tilt, then cause the tenesmus of material and the paralysis of lowering or hoisting gear or damage.
Heat-treatment furnace is a kind of equipment for being heat-treated to metal, is divided into flame furnace and electric furnace according to heat-supplying mode Two classes, can be divided into cycle stove and continuous oven again according to thermal regulation.Wherein, continuous oven refers to that stove is continuously produced, and burner hearth is divided Temperature section, workpiece steps into temperature controlled region by preheating zone successively.The metal works handled via continuous oven have any surface finish, The characteristics of hardness is uniform, morphotropism is small.But, current continuous oven is all individual layer, and workpiece discharges from an endfeed other end.This Generally there is the relatively low defect of yield in the body of heater of type.In addition, heating stroke of the workpiece in stove is the furnace superintendent of body of heater, In order to improve the thermal effectiveness of workpiece, in the case where not changing the transmission speed of workpiece, it usually needs increase heat-treatment furnace Overall length.But not only equipment cost is higher for the heat-treatment furnace of this structure design, and the overall floor space of equipment compared with Greatly.Meanwhile, discharging opening and charging aperture are arranged at body of heater both sides, cross-ventilation is easily formed, causes oxidation and decarbonization.
In order to solve this problem, while heat-treatment furnace body length is not increased, heat treatment of workpieces effect is improved, can By in heat-treatment furnace set Multi-layer transmission device, workpiece a certain layer heating after, by another layer heat after transmit to Outside stove, the double-deck heat treatment of workpiece is then realized.But it is due to that workpiece needs to be transported to another layer from one layer in stove, so necessary One end sets lifting transmission mechanism in stove.But the setting of elevating mechanism must keep lifting region and heat-treatment furnace burner hearth temperature Degree is consistent.In addition, must be provided with transmission device on the transmission up and down in order to realize material, the bin of elevating mechanism.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of single power source that can be applied to multilayer heat-treatment furnace end Driving is lifted, lifting regional temperature is controllable and lifts the high temperature rotating elevating mechanism that transmission device is set on bin.
The present invention solves the technical scheme that is used of above-mentioned technical problem:A kind of high temperature rotating elevating mechanism, including rise Region, lift drop, and the lift includes lowering or hoisting gear, and the lowering or hoisting gear includes a PTO, the liter Drop region and be provided with multiple heating element heaters, cooling system, the lift top both sides are provided with two hoisting rotation axles, described two Hoisting rotation axle is connected with a PTO, and drive sprocket is respectively arranged with the hoisting rotation axle, The drive sprocket is connected by chain with lifting traveling table, and the lifting traveling table is lived provided with lifting adjustable shelf, lifting Moving frame is provided with transmission device, and the transmission device is provided with multiple backspin rolls, and the transmission device passes through in lowering or hoisting gear Power transmission shaft be connected with motor.
