Description

Technical Field

[0001] The utility model relates to the technical field of single crystal furnaces, in particular to a pressure roller type guide tube trolley. Background Art

[0002] At present, when using a single crystal furnace to make single crystal rods, the direct pulling method is usually adopted. This method is to put polycrystalline silicon into the single crystal furnace, melt it at high temperature, and then go through multiple processes to complete the pulling of single crystal silicon rods. Then, after the single crystal furnace is cooled, the guide tube in the single crystal furnace needs to be cleaned. When cleaning the guide tube in the single crystal furnace, it is necessary to first take the guide tube out of the single crystal furnace, and use a trolley to move the guide tube to the designated position, and then clean it. Currently, the single crystal furnaces of most companies are disassembled frequently every month.

[0003] However, some guide tube trolleys now use grooved pulleys to limit the guide tube. The gravity of the guide tube is relatively large. During the transportation process, the grooved pulley is greatly worn, which can easily cause damage to it and endanger the safety of the operator. At the same time, the grooved pulley also causes serious wear on the lower edge of the guide tube's felt cover, thereby increasing the company's cost. For this reason, we propose a pressure roller guide tube trolley to solve the above problems. Utility Model Content
