Hoisting device for single crystal furnace guide cylinder

Abstract

The invention relates to a hoisting device for a single crystal furnace guide cylinder. The hoisting device includes a hoisting plate, a positioning column, L-shaped transmission plates and L-shaped clamps, wherein the positioning column is hollow, the upper end of the positioning column is rotatably connected with the bottom of the hoisting plate; the top of the hoisting plate is provided with aboom mounting mechanism; the positioning column is internally provided with a lifting mechanism; L-shaped transmission plates are arranged on both sides of the positioning column; L-shaped transmission plates are connected with transmission screw rods; through troughs are formed on the two side walls of the positioning column; the transmission screw rods are connected with the lifting mechanism through the through troughs; electric cylinders are arranged on the outer walls of the two L-shaped transmission plates; and two L-shaped clamps are connected with the two electric cylinders on the twoL-shaped transmission plates. The hoisting device has the advantages of simple structure, easy manufacture, practicality and high efficiency.

Description

technical field [0001] The invention relates to the technical field of single crystal furnaces, in particular to a hoisting device for a single crystal furnace guide tube. Background technique [0002] At present, single crystal silicon is usually produced by using a single crystal furnace. The main components of the single crystal furnace from bottom to top include furnace floor, furnace body, furnace cover, flap box, auxiliary furnace, etc., and jackets are installed inside each part. layer, cooling water circulates in the jacket. Monocrystalline silicon is generally produced by the following method: put polycrystalline silicon into a quartz crucible in the furnace body, polycrystalline silicon is heated and melted in the quartz crucible, and then the molten silicon is cooled slightly to give a certain degree of supercooling, and the seed crystal is placed in the furnace. In the silicon seed crystal holder, the upper end of the seed crystal holder is connected to the seed...

AI Technical Summary

Problems solved by technology

Many existing manufacturers put the guide tube into the single crystal furnace through manual handling. Due to the heavy weight of the guide tube, it is very difficult to lift

There are also some manufacturers who use hoisting for transportation. However, these hoisting mechanisms are complex in structure and high in cost. It takes time and effort to disassemble and assemble each time, and it is easy to shake or even fall during hoisting, which is more dangerous.
