Description

Technical Field

[0001] This utility model relates to the photovoltaic manufacturing industry, specifically a quartz crucible lifting device. Background Technology

[0002] Quartz crucibles are used in the pulling of single-crystal silicon rods in a single-crystal furnace. Each furnace pull consumes one quartz crucible, making them consumables that cannot be reused. The quantity used is enormous. Upon arrival, the quartz crucibles are wrapped in an outer cardboard box or PVC plastic box, approximately 1 meter in length, width, and height. An inner plastic film bag contains the crucible to prevent contamination. Foam is used as shock-absorbing filler in the middle, with filler only at the bottom and top, leaving gaps around the edges. After opening the cardboard box and removing the top filler, the quartz crucible needs to be removed and placed on a crucible transport vehicle before being taken to the material preparation room to be loaded with silicon material. Each quartz crucible weighs approximately 80 kilograms and has a U-shaped overall structure with no gripping handles or force points; the rounded bottom also prevents it from bearing weight. Typically, two workers hold the plastic bags containing the quartz crucibles, lift the crucibles from the cardboard boxes, and place them on the crucible transport vehicle. This is a simple and quick process, but it has problems: each quartz crucible weighs 80 kilograms. Two people can handle one crucible, but opening numerous crucibles in this way is physically demanding for the workers. The plastic bags may also break at any time, causing the crucibles to fall and shatter or crack. Alternatively, impacts with metal or other hard objects during handling can cause cracks, chipping, or other damage, directly rendering the crucibles unusable. Using clamps to handle the quartz crucibles also presents problems: quartz crucibles are made of brittle materials, and defects such as air bubbles, microcracks, and internal stress may exist during the manufacturing process. The transportation and handling processes also involve impacts and other defects. Applying clamping force after opening the boxes can further damage the crucibles.

[0003] Existing methods, whether manual or using existing lifting equipment, carry the risk of damaging the quartz crucible, causing unnecessary losses. To reduce these risks and minimize losses, the applicant proposes a device specifically designed for lifting quartz crucibles. Utility Model Content

[0004] The purpose of this utility model is to provide a quartz crucible lifting device. This device is specifically designed for lifting quartz crucibles without applying clamping force to the crucibles. It also eliminates the need for manual contact with the crucibles, greatly reducing the risk of damage and contamination. Furthermore, it can be easily operated by one person, reducing labor intensity and saving labor costs.

[0005] To achieve the above objectives, the present invention proposes the following technical solution: a quartz crucible lifting device, comprising a lifting frame, a lifting assembly, and an adjusting assembly. The lifting assembly is mounted on the lifting frame, and the wire rope of the lifting assembly is connected to the adjusting assembly. The adjusting assembly is provided with a rotating arm, and a clamping arm is fixedly connected to the lower end of the rotating arm.

[0025] like Figure 1-3As shown, this embodiment provides a quartz crucible lifting device, including a hanger 1, a lifting assembly, and an adjusting assembly. The hanger 1 serves as the basic frame of the entire device, supporting the lifting assembly and the adjusting assembly. Casters are provided at the bottom of the hanger 1, facilitating the movement and positioning of the device, significantly improving its portability and flexibility, and making it suitable for various scenarios. The lifting assembly is mounted on the hanger 1, and its steel wire rope 5 is connected to the adjusting assembly. A rotating arm 7 is provided on the adjusting assembly, and a clamping arm 8 is fixedly connected to the lower end of the rotating arm 7. The adjusting assembly is used to adjust the opening or closing of the clamping arm 8. The clamping arm 8 directly grips and secures the crucible, and its lower arc-shaped design fits tightly against the crucible surface. Engineering plastics are used to reduce damage to the crucible surface.

[0026] In this embodiment, the lifting assembly includes an electric winch 4 and a pulley, as well as a remote controller 3 and a battery 2. The battery 2 provides power to the electric winch 4, and the remote controller 3 controls the opening and closing of the electric winch 4. The electric winch 4 is fixedly installed on the upper end of the frame 1, providing lifting power for raising and lowering the wire rope 5. The pulley is movably connected to the upper end of the frame 1, changing the direction of the wire rope and reducing friction. One end of the wire rope 5 is connected to the electric winch 4, and the wire rope 5 passes around the pulley and connects to the adjusting assembly, transmitting tension. The electric control of the lifting of the quartz crucible 9 reduces the burden of manual operation and improves the accuracy and efficiency of lifting. The surface of the wire rope 5 is covered with plastic, which prevents wear and extends its lifespan.

[0027] In this embodiment, the adjustment assembly includes a lifting ring 11, a screw 12, a fixed frame 13, a nut 14, and a moving block 16. The upper end of the lifting ring 11 is connected to the wire rope 5 to bear the tension. The lower end of the lifting ring 11 is fixedly connected to the screw 12. The nut 14 is threadedly connected to the screw 12, achieving precise adjustment through threaded transmission. This drives the moving block 16 and the rotating arm 7 to move. One end of the moving block 16 is fixedly connected to the nut 14, and wear-resistant sleeves 15 are provided on both the moving block 16 and the nut 14. The other end of the moving block 16 is movably connected to the rotating arm 7, which is movably connected to the fixed frame 13. The rotation of the screw 12 drives the nut 14 to rise and fall, and through the moving block 16 and the rotating arm 7, it drives the clamping arm 8 to rotate, open, or close. This achieves stable gripping and release of the quartz crucible 9, avoiding damage to the surface of the quartz crucible caused by metal. Through screw transmission, the operation is smooth and reliable, and the opening and closing range can be precisely controlled.

[0028] In this embodiment, a handwheel 6 is fixedly connected to the upper part of the nut 14 for manual adjustment of the nut 14, which facilitates fine-tuning of the opening and closing of the arm.

[0029] In this embodiment, the retaining arm 8 is made of engineering plastic material, which contacts the quartz crucible 9 to prevent contamination and damage to the crucible. The lower end of the retaining arm is arc-shaped and fits tightly with the rounded corner of the crucible.

[0030] In use, the quartz crucible 9 is located in the cardboard box 10. First, the opening and closing of the clamping arm 8 is finely adjusted. The rotation of the screw 12 can be manually controlled by the handwheel 6 to achieve more precise action. At this time, the rotation of the screw 12 drives the nut 14 to rise, and through the moving block 16 and the rotating arm 7, it drives the clamping arm 8 to rotate and open. Then, to prepare to lower the clamping arm 8, the electric winch 4 is started. The wire rope 5 transmits tension through the pulley, driving the lifting ring 11 to descend. The wire rope drives the clamping arm 8 to descend through the lifting ring 11. When the paper reaches the appropriate height, the handwheel 6 is turned in the opposite direction to close the clamping arm 8. The arc-shaped lower end of the clamping arm 8 fits with the rounded corner of the quartz crucible 9 to achieve a stable grip. When the clamping arm opens, the crucible can be released to achieve the overall lifting or placement of the crucible. The electric winch 4 is then reversed, causing the wire rope 5 to lift the boom 8 via the lifting ring 11. The casters at the bottom of the lifting frame 1 allow the device to move freely between different work sites. The casters can be locked to ensure stability during use. Once the device is moved to a suitable position, the quartz crucible 9 can be lowered. Overall, this device integrates portability, safety, and efficiency, and is particularly suitable for the frequent lifting needs of quartz crucibles in industrial production.
