Door-opening type stick-withdrawing vehicle of single crystal furnace

Abstract

The invention provides a door-opening type stick-withdrawing vehicle of a single crystal furnace, relating to a stick-withdrawing vehicle of a single crystal furnace. The stick-withdrawing vehicle comprises a vehicle frame, wherein the bottom of the vehicle frame is provide with an orientation wheel and a universal wheel with a brake; the vehicle frame is provided with a lifting system and a horizontal telescopic clamping system; and the lifting system mainly comprises an oil pump component, an oil box, a hydraulic cylinder, a top rod, a lifting-up footboard, a lifting-down footboard, a lifting guide rod, a guide rod bracket and a guide rod limiting board. The horizontal telescopic clamping system is arranged above the top rod of the hydraulic cylinder, and mainly comprises a telescopic hand wheel, a telescopic screw rod, a guide cylinder, a telescopic arm, a clamping screw rod, a clamping hand wheel, a locking pin, a pressing arm, a clamping block, a shaft pin, a pallet, a chain and a suspending hook. The door-opening type stick-withdrawing vehicle can avoid the accident and overcome the quality problem of the product since workers are scalded when withdrawing the stick to lead a single crystal silicon stick to be fallen off, thereby being capable of safer and more accurately completing the process of stick withdrawing.

Description

Technical field: [0001] The invention relates to a rod fetching car used in conjunction with an open-door single crystal furnace. Background technique: [0002] The rod extraction process of the single crystal furnace is mainly carried out manually, and after the production of the single crystal silicon rod, the temperature is extremely high, and the manual method has a high risk factor, which is prone to burn accidents and the drop of the single crystal silicon rod. Affect product quality, and the accuracy of manual rod removal is low, and the monocrystalline silicon rod is easy to swing, causing the seed crystal to break, which will also cause quality accidents. At present, there is no better way to solve the rod removal process of the open-door single crystal furnace of these issues. Invention content: [0003] The invention provides an open-door type single crystal furnace rod taking car, which avoids scalding accidents caused by manual rod removal, ensures product qu...
