Abstract
The utility model relates to a lifting device of a flow guide drum of a single crystal furnace, belonging to the technical field of an auxiliary tool of the single crystal furnace. The lifting device comprises the flow guide drum and a special lifting tool of the flow guide drum, wherein an upper port of the flow guide drum is provided with flanges; the upper end surface of the flow guide drum is provided with three hooks which are uniformly distributed by taking the axis of the flow guide drum as the center; the root parts of the hooks are fixed on the flanges of the flow guide drum by hook bolts, and the end parts of the hooks are bent towards the inside of the flow guide drum; the lifting tool comprises a lifting rod, lifting arms and lifting lugs; the upper end of the lifting rod is provided with a lifting rod suspending hole; three hinged claws are uniformly distributed on the circumference of the lifting rod; the root parts of the hinged claws are respectively welded on the circumference of the lifting rod; the upper ends of the lifting arms are respectively hinged on the corresponding hinged claws by bolts; the lifting lugs are respectively welded at the lower ends of the lifting arms and are respectively provided with a suspending hole; and the suspending holes are respectively hooked at the hooks on the flow guide drum. When the flow guide drum is in place, the flanges are supported, the lifting rod falls, the lifting arms falls by self gravity, and then the lifting lugs are separated from the hooks.
Description
Technical field
The utility model relates to a kind of lifting gear of single-crystal furnace guide shell, belongs to single crystal growing furnace auxiliary means technical field.
Background technology
At present, use single crystal growing furnace to produce silicon single crystal usually, single crystal growing furnace major parts from bottom to top has drop-bottom, body of heater, bell, perble range, secondary stove etc. successively, is equipped with the chuck layer in each parts, and circulation has water coolant in the chuck.The following method manufacturing of the general employing of silicon single crystal: polysilicon is put in the intravital quartz crucible of stove, polysilicon is heated fusing in quartz crucible, then, will melt silicon and slightly do cooling, give certain condensate depression, seed crystal is packed in the silicon seed clamper, the upper end of seedholder is connected with seed shaft by web member, and seed crystal is fixed in the lower end of clamper, and makes seed crystal insert silicon melt through guide shell, by the temperature of adjusting melt and the pulling speed that seed crystal makes progress, seed body is grown up.
Guide shell is up big and down small conically shaped, and the upper port of guide shell is provided with flange.Because guide shell weight is heavier, promote very difficulty, when hanging out, hoisted in position or dismounting all waste time and energy.
The utility model content
The purpose of this utility model is, overcomes problems of the prior art, and a kind of lifting gear of single-crystal furnace guide shell is provided, and can reduce the difficulty that guide shell promotes greatly.
For solving above technical problem, the lifting gear of a kind of single-crystal furnace guide shell provided by the utility model, the special hanger that comprises guide shell and guide shell, described guide shell is up big and down small conically shaped, the upper port of guide shell is provided with flange, the upper surface of described guide shell is equipped with hook, described hook is that the center is evenly distributed with three with the axis of described guide shell, the root of described hook is fixed on by hook bolt on the flange of described guide shell, and the end of described hook is crooked in guide shell; Described suspender comprises suspension rod, arm and hanger, the upper end of described suspension rod is provided with the suspension rod suppending hole, be evenly equipped with three hinge finger on the circumference of described suspension rod, the root of described hinge finger is welded on respectively on the circumference of described suspension rod, the upper end of described arm is hinged on respectively on the corresponding hinge finger by bolt, described hanger is welded on the lower end of described arm respectively, is respectively equipped with suspension eye on the described hanger, and described suppending hole hooks the described hook on the guide shell respectively.
With respect to prior art, the utility model has been obtained following beneficial effect: three hangers with suspender are hooked in respectively on three hooks of guide shell earlier, and the upper end of suspension rod is mentioned, and hanger is stressed to remain on the hook, then guide shell has been carried transhipment; When guide shell hung in the body of heater in place after, the flange of guide shell is supported, suspension rod descends, arm relies on the gravity fall of self, hanger promptly breaks away from hook; By means of special hanger, the handling of guide shell is very convenient, and is time saving and energy saving.
