[0002] Single crystal furnace is an essential equipment in the process of converting polycrystalline silicon into single crystal silicon, and single crystal silicon is the basic raw material in photovoltaic power generation and semiconductor industry. As the key supporting material of modern information society, single crystal silicon is one of the most important single crystal materials in the world. It is not only the main functional material for the development of computers and integrated circuits, but also the main functional material for photovoltaic power generation using solar energy.

[0003] The rod retrieval operation can be regarded as moving a 85 kg, 1600 mm long, 100-160 mm in diameter cylinder with a high temperature from the auxiliary furnace chamber 1.8 meters above the ground, using the tungsten wire rope in the single crystal furnace. The tungsten wire rope is connected to the weight and connected to the crystal rod. By controlling the lifting of the tungsten wire rope, the crystal rod is lowered from the auxiliary furnace chamber to the rod retrieval car, and the rod is retrieved by the rod retrieval car.

[0004] The existing rod-taking vehicles can generally only take out the rods, and need multiple tools to complete the work of transporting and placing them horizontally. It is impossible to use one vehicle to complete the three functions of taking out the rods, placing them horizontally and transporting them. Utility Model Content
