Description
Technical field
The utility model relates to a kind of polycrystalline silicon ingot or purifying furnace, specifically relates to a kind of polycrystalline silicon ingot or purifying furnace lower furnace body synchronous lifting device.
Background technology
Silicon is a kind of important electron, optical material, plays an important role in wide fields such as information, communication, space flight, environment protection, and the market requirement is increasing.Polycrystalline silicon ingot or purifying furnace is the important production unit of production solar energy power generating field polysilicon.Polycrystalline silicon ingot or purifying furnace is mainly produced silicon semiconductor material with ingot ways at present, and traditional polycrystalline silicon ingot or purifying furnace is made up of upper furnace body and lower furnace body, in the shove charge and blow-on process of polycrystalline silicon ingot or purifying furnace, need rise and step-down operation to lower furnace body.The lower furnace body lifting device of existing polycrystalline silicon ingot or purifying furnace overlaps independently by three, and lifting motor constitutes; Three lifting motors connect three points of lower furnace body respectively; Drive lower furnace body and go up and down, three motor synchronous property of this mode are difficult to guarantee that the lower furnace body lifting process is unstable.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of polycrystalline silicon ingot or purifying furnace lower furnace body synchronous lifting device is provided, and it can effectively guarantee the stability that lower furnace body goes up and down.
The purpose of the utility model is achieved in that a kind of polycrystalline silicon ingot or purifying furnace lower furnace body synchronous lifting device; It comprises support and lower furnace body; Be characterized in: said top of the trellis is provided with three cover worm and gear assembly and motors; Said three cover worm and gear assemblies are along circumferentially evenly arranging; Said motor is positioned at wherein cover worm and gear assembly one side and its output terminal is connected with this cover worm and gear assembly through belt, and said lower furnace body outer wall upper edge circumferentially evenly is provided with three permanent seats, all is set with leading screw on said three permanent seats; Said leading screw and worm and gear assembly are meshing with each other, and interconnect through shaft coupling and flexible axle between the said three cover worm and gear assemblies.
Also be provided with the flexible axle retaining plate on the said lower furnace body outer wall, said flexible axle retaining plate is positioned at the below of flexible axle, and the flexible axle retaining plate is provided with set collar, and said flexible axle passes the set collar on the flexible axle retaining plate.
Compared with prior art, the beneficial effect of the utility model is:
A kind of polycrystalline silicon ingot or purifying furnace lower furnace body of the utility model synchronous lifting device; It couples together three cover worm and gear assemblies through flexible axle, through an electric motor driving, has realized synchronous interaction; Thereby guaranteed the levelness when lower furnace body goes up and down; It is more steady that lower furnace body is gone up and down, and hoisting appliance is not fragile, and work-ing life is longer.
