[0002] Sapphire crystal is the most basic single crystal form of aluminum oxide. It has a series of excellent physical and chemical properties, such as high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance, good light transmission, and excellent electrical insulation properties. Therefore, it is widely used in various demanding fields such as national defense, scientific research, and civilian industry.

[0003] The crucible is a crucial and essential component in the sapphire crystal growth process. From the initial filling of raw materials to their melting, ingot growth, and finally ingot removal, all processes take place within the crucible. Therefore, the crucible plays a vital role in sapphire crystal growth. Crucibles are typically made of tungsten-molybdenum, making them quite heavy. Their proximity to the heating element also constrains the design of the thermal field.

[0004] Currently, most of the crucible fixtures used with crucibles have complex structures. During the removal or placement process, they can easily come into contact with the heater, causing it to break. In addition, they are cumbersome to use and greatly increase labor costs. Utility Model Content

[0005] One of the technical problems that this disclosure aims to solve is that most of the crucible fixtures currently used with crucibles have relatively complex structures, and the heater is easily damaged during removal or placement, which can lead to heater breakage. In addition, they are cumbersome to use.

[0006] To solve the above-mentioned technical problems, this disclosure provides a crucible hoisting tool, which includes: at least two fixing plates, the fixing plates being arc-shaped plates, a hoisting space being formed between the at least two fixing plates for hoisting the crucible body, and the fixing plates being used to fit against the outer wall of the crucible body, and at least one rope fixing part being provided on the outer side of the fixing plates;

[0013] In some embodiments, a support plate is provided on the bottom side of the fixing plate facing the hoisting space to support the bottom of the crucible body.

[0014] In some embodiments, the bottom surface of the pallet is provided with a limiting groove corresponding to the trajectory of the corresponding hoisting rope, and the limiting groove is used to accommodate part of the hoisting rope.

[0015] In some embodiments, the connection between the tray and the fixing plate is smoothly transitioned.

[0016] In some embodiments, at least one limiting rope is connected between the hoisting ropes corresponding to the adjacent sides of the two fixing plates, and the limiting rope is used to fit against the outer wall of the crucible body.

[0035] Example

[0036] Reference Appendix Figure 1 -Appendix Figure 2To address the aforementioned problems, this utility model provides a crucible lifting tool, comprising: at least two fixing plates 1, each fixing plate being an arc-shaped plate, forming a lifting space between the at least two fixing plates 1 for lifting the crucible body 5, and the fixing plates 1 being used to fit against the outer wall of the crucible body 5; at least one rope fixing part 11 being provided on the outer side of the fixing plates 1; at least two lifting ropes 2, each lifting rope 2 passing around the bottom side of the lifting space, and both ends being connected to the rope fixing parts 11 of the two fixing plates 1 respectively; and a fixing buckle 3, used to concentrate and fix the portions of the at least two lifting ropes 2 near their ends to the top side of the lifting space, so that the lifting joint is connected to the ends of the at least two lifting ropes 2; wherein, the portions of the at least two lifting ropes 2 located on the bottom side of the lifting space intersect.

[0037] Specifically, the crucible lifting tool provided in this embodiment is used for lifting crucibles used in sapphire crystal growth, specifically in the processing of sapphire grown using the Czochralski method. The crucible lifting tool includes at least two fixing plates 1, at least two lifting ropes 2, and fixing buckles 3. All the lifting ropes 2 are connected to the corresponding fixing plates 1, forming a lifting space. During lifting, the lifting ropes 2 support the bottom of the crucible body 5, and the fixing plates 1 are respectively attached to the outer wall of the crucible body 5 for lateral restraint. The fixing buckles 3 connect the ends of all the lifting ropes 2 together, allowing reliable lifting through shackles, hooks, or other lifting joints. The height of the fixing buckles 3 can be set according to the height of the crucible body 5. This design simplifies the structure of the crucible lifting tool, facilitates connection, occupies little space, and improves operational convenience and efficiency.

[0038] Reference Appendix Figure 1 and attached Figure 2 The fixing plate 1 is an arc-shaped plate and can be made of stainless steel. At least two fixing plates 1 are used in combination to form a hoisting space that is adapted to the diameter of the crucible body 5, which can improve the practicality and applicability of the crucible hoisting tool. Each fixing plate 1 has at least one rope fixing part 11 on its outer side. The rope fixing part 11 can connect the hoisting rope 2 to the fixing plate 1, and at least limit the relative position of the two during the hoisting process. The number of rope fixing parts 11 on the outer side of each fixing plate 1 can be determined according to the number of fixing plates 1 used, and must meet the requirements of the stability of the hoisting rope 2 supporting the crucible body 5 and the reliability of the connection between the hoisting rope 2 and the fixing plate 1.

[0039] Reference Appendix Figure 1 and attached Figure 2The lifting rope 2 can be, but is not limited to, steel wire rope. The number of lifting ropes 2 can be determined according to the number of fixing plates 1 used, or the number of lifting ropes 2 can be increased to enhance the stability of the lifting. In use, the middle part of each lifting rope 2 is placed between the bottoms of multiple fixing plates 1, that is, at the bottom of the lifting space. Then, the two ends of each lifting rope 2 are connected to the rope fixing parts 11 on two of the fixing plates 1 respectively. Finally, the ends of all the lifting ropes 2 are placed on the top side of the lifting space, and the parts of all the lifting ropes 2 near the ends are fixed together by the fixing buckle 3 to facilitate the connection of lifting hooks and other lifting joints to realize the lifting process. The connection method between the fixing buckle 3 and the ends of the lifting rope 2 can be sleeve, snap, etc., which is not specifically limited here.

[0040] Reference Appendix Figure 2 To improve the stability of lifting the crucible body 5, at least two of the lifting ropes 2 used in the crucible lifting tool can be arranged to have intersection points on the bottom side of the lifting space. This arrangement can prevent the lifting ropes 2 at the bottom of the crucible body 5 from separating during the lifting process, thus affecting the stability of the lifting. Taking the use of four fixing plates 1 as an example, to improve the lifting stability, a total of four lifting ropes 2 can be used. Each fixing plate 1 is provided with two sets of rope fixing parts 11 along the circumference of the crucible body 5. Each set of rope fixing parts 11 can include at least two rope fixing parts 11 spaced apart along the axial direction of the crucible body 5. Every two lifting ropes 2 form a group and are connected to two opposite fixing plates 1. In this way, the four lifting ropes 2 form four intersection points at the bottom of the lifting space, which can form a stable support part.

[0041] Based on the above, this utility model embodiment proposes a crucible lifting tool. At least multiple lifting ropes 2 can connect all the fixing plates 1, forming a lifting space between them. The portion of the lifting ropes 2 at the bottom of the lifting space can support the bottom of the crucible body 5. During lifting, the fixing plates 1 are respectively attached to the outer wall of the crucible body 5 to achieve lateral positioning. Fixing buckles 3 can connect the ends of all the lifting ropes 2 together, so that they can be connected to the ends of the lifting ropes 2 through lifting joints such as hooks, achieving reliable lifting. This design simplifies the structure of the crucible lifting tool, facilitates connection, occupies little space, and improves the convenience and efficiency of operation.

[0042] Reference Appendix Figure 1 and attached Figure 2 In specific implementation, there are two fixing plates 1; each fixing plate 1 has at least two rope fixing parts 11 on both sides along the circumferential direction of the crucible body 5, and the rope fixing parts 11 on the same side are distributed at intervals along the axial direction of the crucible body 5.

[0043] Specifically, in order to simplify the structure of the crucible hoisting tool while ensuring the stability and reliability of the hoisting, the technical solution adopted in this utility model can use two fixing plates 1. The two fixing plates 1 can be set with the same size and shape. Two rows of rope fixing parts 11 are arranged on the outer side of each fixing plate 1 along the circumference of the crucible body 5. Each row includes at least two rope fixing parts 11 distributed at intervals along the axial direction of the crucible body 5. The at least two rope fixing parts 11 in each row are used to connect the same hoisting rope 2, so that the hoisting rope 2 can have at least two connection positions with each fixing plate 1 to ensure the reliability of the connection. With this design, the two ends of each hoisting rope 2 pass through the two rows of rope fixing parts 11 on the two fixing plates 1 located on different sides, so that the two hoisting ropes 2 can cross at the bottom of the hoisting space to stably support the crucible body 5.

[0044] Reference Appendix Figure 1 In specific implementation, the rope fixing part 11 can be set as a fixing sleeve extending along the axial direction of the crucible body 5. When the hoisting rope 2 is connected, it can pass through the inside of the fixing sleeve. The inner diameter of the fixing sleeve can be set to match the diameter of the hoisting rope 2, which can reduce the movement of the hoisting rope 2 inside the fixing sleeve and improve the stability of the position of the hoisting rope 2 during hoisting.

[0045] In order to facilitate the insertion of the hoisting rope 2 into the rope fixing part 11, a guide ring groove that connects with the inner wall of the fixing sleeve can be provided at the lower end of the fixing sleeve. The inner diameter of the guide ring groove gradually increases from the inside of the fixing sleeve to the lower end. This inclined guide makes it easier to insert the hoisting rope 2 into the rope fixing part 11, improving the convenience of operation for the staff.

[0046] Reference Appendix Figure 3 In practice, a support plate 4 is provided on the bottom side of the fixed plate 1 facing the hoisting space to support the bottom of the crucible body 5.

[0047] Specifically, in order to improve the stability of hoisting and reduce the stress on the hoisting rope 2, the technical solution adopted in this utility model is to fix a support plate 4 at the bottom of the fixed plate 1. The support plate 4 faces the side where the hoisting space is located to form an "L"-shaped support structure. The support plate 4 extends along the bottom edge of the arc-shaped fixed plate 1. After the hoisting rope 2 is connected to the fixed plate 1, the support plate 4 can play the role of supporting the crucible body 5 synchronously with the hoisting rope 2 located at the bottom, which can share the weight of the crucible body 5 and improve the reliability of the hoisting process.

[0048] Among them, reference appendix Figure 1To avoid wear and tear on the lifting rope 2 during long-term use, a smooth transition can be made at the joint between the support plate 4 and the fixing plate 1. This way, the contact point of the lifting rope 2 at the joint is rounded, which can reduce wear on the lifting rope 2 and improve the reliability and service life of the lifting rope 2.

[0049] Reference Appendix Figure 1 In specific implementation, the bottom surface of the pallet 4 is provided with a limiting groove 41 corresponding to the trajectory of the corresponding hoisting rope 2. The limiting groove 41 is used to accommodate part of the hoisting rope 2.

[0050] Specifically, in order to further improve the reliability of the position of the hoisting rope 2, the technical solution adopted in this utility model can be based on the position and trajectory of the hoisting rope 2 passing through the bottom surface of the pallet 4. A limiting groove 41 corresponding to the position passed by the hoisting rope 2 can be opened on the bottom surface of the pallet 4. The limiting groove 41 can be set as an arc groove adapted to the diameter of the hoisting rope 2, which can accommodate part of the hoisting rope 2 and limit the position of the hoisting rope 2 to a certain extent, so as to maintain the relative position of the hoisting rope 2 and the pallet 4 during the hoisting process.

[0051] In practice, at least one limiting rope (not shown in the figure) is connected between the hoisting ropes 2 corresponding to the adjacent sides of the two fixed plates 1. The limiting rope is used to fit against the outer wall of the crucible body 5.

[0052] Specifically, in order to further improve the limiting effect on the crucible body 5 during hoisting, the technical solution adopted in this utility model is to connect at least one limiting rope between the hoisting ropes 2 connected to the adjacent sides of the two fixed plates 1. The limiting rope extends circumferentially to the crucible body 5 and can fit against the side of the crucible body 5 during hoisting, which can prevent the crucible body 5 from falling between the two fixed plates 1, thus playing an effective protective role and not taking up unnecessary space. The two ends of the limiting rope can be detachably connected to the hoisting rope 2 through detachable parts, which makes it easy to replace the limiting rope of appropriate length to adapt to crucible bodies 5 of different sizes.

[0053] Reference Appendix Figure 1 In specific implementation, the two fixed plates 1 are movably connected to each other on adjacent sides by limiting beams (not shown in the figure), which extend along the circumference of the crucible body 5.

[0054] Specifically, in order to further improve the limiting effect on the crucible body 5 during hoisting, in addition to adding limiting ropes, the technical solution adopted by this utility model can also set a limiting beam extending circumferentially between the two fixing plates 1. During hoisting, it can fit against the side of the crucible body 5, which can prevent the crucible body 5 from falling between the two fixing plates 1, thus playing an effective protective role, and will not occupy unnecessary space. The two ends of the limiting beam can be detachably connected to the corresponding fixing plate 1 through detachable parts, which makes it easy to replace the limiting beam of appropriate length to adapt to crucible bodies 5 of different sizes.
