Description

TECHNICAL FIELD

BACKGROUND

[0002] With the continuous expansion of photovoltaic market and the increase of installed capacity year by year, the demand for single crystal furnace equipment and its supporting thermal field products also rises. As the core equipment in the photovoltaic industry chain, the performance of single crystal furnace directly affects the quality and yield of single crystal silicon rod. As a key component of single crystal furnace, the quality and stability of thermal field products are crucial to the normal operation of single crystal furnace. Crystal pulling furnace is a device used for growing single crystal materials, which melts polycrystalline materials by heating, and then crystallizes and grows under a certain temperature gradient to form the desired single crystal. To improve the efficiency of photovoltaic thermal field crystal pulling, the size of crystal pulling furnace has been upgraded from the traditional 32 inches to 39 inches, and even some crystal furnace thermal field sizes reach more than 40 inches. The large size of crystal pulling furnace makes its supporting thermal field products adapt to large-scale adjustment. During production and preparation, due to the high weight, large size and scattered force points of large-size thermal field products, the production efficiency of the products is greatly affected, and the production cost of the enterprise is increased.

[0048] The upper lifting arm 6 is two-piece structure, and fixing holes are formed at both ends and near the lower end, a protrusion is arranged at the position where the upper lifting arm base 2 is connected with the upper lifting arm 6, the protrusion is provided with a through hole, and the upper end of the upper lifting arm 6 is fixed by a bolt and a nut, a protrusion is arranged at the top end of the lower lifting arm 11, the protrusion is provided with a through hole, and the end of the upper lifting arm 6 is fixed by a bolt and a nut, and the upper lifting arm 6 and the lower lifting arm 11 can rotate around the bolt. The support arm 8 is a single-piece structure, and through holes are formed at both ends, the position where the lower lifting arm base 5 is connected with the support arm 8 is a U-shaped ear seat, the U-shaped ear seat and the end of the support arm 8 are provided with through holes, and are fixed by a bolt and a nut, the other end of the support arm 8 is fixed by a bolt and a nut at the fixing hole formed near the lower end of the upper lifting arm 6, the support arm 8 can move in the gap between the two-piece lifting arms, and a nylon sleeve 12 is sleeved on the lower lifting arm 11.

[0049] Referring to Figure 7 and Figure 8 , the large-size photovoltaic / semiconductor thermal field spare's quick hoisting tooling of the utility model is used as follows:

[0050] After the lower hanging arm 11 is stretched outwards unilaterally, a large-size, thin-wall photovoltaic or semiconductor thermal field piece 14 (such as a crucible, a flow guide cylinder, a heat preservation cylinder, a heater, etc.) is placed in the center, ensuring that the thermal field piece 14 is in contact with the clamping jaw 13. An upward force is applied to the lifting ring 1, and the upper hanging arm 6 and the lower hanging arm 11 are subjected to a downward tensile stress. When the load is transmitted to the upper hanging arm seat 2, the upper hanging arm seat 2 moves downward, the spring 4 is compressed, the upper hanging arm 6 is subjected to a tensile stress, the support arm 8 is subjected to a compressive stress, the lower hanging arm 11 receives an inward force and compresses the thermal field piece 14 to form a compressive stress, and the clamping jaw 13 supports the thermal field piece 14, thereby firmly holding it and achieving rapid handling of the thermal field piece. After the thermal field piece 14 is transported to the designated location, it needs to be disassembled. After the force on the lifting ring 1 is cancelled, the compressive stress of the spring 4 drives the upper hanging arm seat 2 to move upward. When it moves to the protruding limit position of the lifting rod 3, the movement of the upper hanging arm seat 2 stops. The upper hanging arm seat 2 automatically returns to the original state upwardly under the action of the spring 4. The support arm 8 receives a downward compressive stress, so that the upper hanging arm 6 opens outward, thereby driving the lower hanging arm 11 to separate from the thermal field piece 14. The compressive stress of the lower hanging arm 11 and the thermal field piece 14 disappears. The whole process is safe and stable, and can significantly improve the production and handling efficiency.

[0051] In summary, the new lifting tool is designed for the rapid lifting requirement of large-size photovoltaic / semiconductor thermal field pieces in the production process. Based on the friction principle, the support feet are uniformly stressed to form stable friction between the supporting arm and the product, avoiding deformation of the large-size product due to uneven stress. After the lifting is completed, the product can be quickly separated by applying pressure to the lifting arm, effectively improving the safety and convenience of product lifting, and having a wide application prospect and economic benefit in the photovoltaic / semiconductor thermal field technology field.

[0052] The above content only illustrates the technical idea of the utility model, and cannot limit the protection scope of the utility model. Any modification made on the basis of the technical solution according to the technical idea of the utility model falls within the protection scope of the utility model claim.
