[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but in appropriate cases, the technologies, methods, and devices should be regarded as part of the specification.

[0031] Referring Figure 1 and Figure 2 , the present disclosure provides a hoisting fixture for a heat-insulating layer in a crucible, including a base 1. A plurality of plate members 3 are annularly arranged on the base 1. A ring buckle mechanism 4 is provided in the central area of the base 1. The base is placed into the groove of the middle heat-insulating layer, and then the plate members are installed to connect with the middle heat-insulating layer. Then, it is connected to the ring buckle mechanism through a hoisting device to carry the middle heat-insulating layer, making the disassembly or installation of the middle heat-insulating layer convenient and fast, ensuring the safety of the operators, reducing the labor cost, and improving the work efficiency. The plate members 3 are inserted into the gaps of the middle heat-insulating layer, and the positions are adjusted to connect the plate members 3 with the base 1.

[0032] In some embodiments, referring to Figure 6 , the ring buckle mechanism 4 includes a shaft portion 401 and a ring portion 402. The shaft portion 401 is threadedly connected to the base 1. The threaded connection enables the locking force between the ring buckle mechanism 4 and the base 1 to adapt to the gravity exerted when the middle heat-insulating layer is lifted. Even under heavy load or vibration conditions, the middle heat-insulating layer can be maintained stable, preventing it from loosening or falling off, which is beneficial to the installation or disassembly of the middle heat-insulating layer. Compared with the way that the ring buckle mechanism 4 and the base 1 are connected by welding or other permanent connection methods, the threaded connection is more flexible and easier to control and use.

[0033] In some embodiments, referring to Figure 1, the base 1 includes a first base 101 and a second base 102. The second base 102 is sleeved with the first base 101 and is located below the first base 101. The second base 102 is connected to the buckle mechanism 4. The base 1 is extended to a double-layer structure including the first base 101 and the second base 102, where the second base 102 is sleeved with the first base 101 to be able to arrange a larger number of plate members 3. It should be noted that, referring to Fig. 2, the middle insulation layer is usually set as a multi-layer structure with a certain gap left between layers to enhance the heat insulation effect. This hoisting jig utilizes this point by placing the plate members 3 in the gaps and then connecting them to the base 1. When the base 1 is lifted, the plate members 3 abut against the middle insulation layer to bear the gravity, so that the middle insulation layer is lifted. By setting the base 1 as multi-layer, it can cooperate with the structure of the middle insulation layer. The plate members 3 not only increase the contact points with the middle insulation layer but also avoid local stress concentration, effectively protecting the structure of the middle insulation layer. In addition, the plate members 3 are distributed in multiple layers of the middle insulation layer, and the forces generated during the hoisting process are more evenly distributed over the entire middle insulation layer, reducing the shaking and swinging of the middle insulation layer and ensuring the smooth progress of the hoisting operation and improving the safety of the operation.

[0034] In some embodiments, referring to Figure 3 , a positioning post 8 and a boss 6 are successively arranged on the second base 102. The first base 101 is formed with a through hole 7. The first base 101 is connected to the second base 102 by the cooperation of the positioning post 8 and the through hole 7. The boss 6 is located away from the second base 102 of the positioning post 8. The diameter of the positioning post 8 is larger than that of the boss 6, which can play a guiding role during the installation of the first base 101. The through hole 7 cooperates with the positioning post 8 to make the connection relationship between the second base 102 and the first base 101 stable and avoid the lateral movement of the first base 101.

[0035] In some embodiments, referring to Figure 3 , an external thread is provided on the outer peripheral surface of the boss 6. The nut 2 is connected to the boss 6 through this external thread. The nut 2 is pressed on the second base 102 to lock the second base 102 and the first base 101, increasing the rigidity and stability of the connection, preventing loosening caused by vibration or external force, and at the same time avoiding the rotation of the second base 102.

[0036] In some embodiments, referring to Figure 3, a mounting hole 9 is formed at the top of the convex platform 6. The mounting hole 9 is provided with internal threads. One end of the shaft portion 401 away from the ring portion 402 is provided with a screw rod. The screw rod is engaged with the internal threads to connect the buckle mechanism 4 to the convex platform 6. Additionally, the shaft portion 401 can be directly connected to the external threads provided on the convex platform 6 to fix the buckle mechanism 4 on the second base 102, making the two fit tightly. The overall structure is stable, and even when subjected to vibration or impact, the buckle mechanism 4 will not loosen or fall off. In addition, by means of the installed buckle mechanism 4 abutting against the nut 2, it can effectively prevent the nut 2 from loosening due to vibration or other reasons during use, thereby ensuring the reliability of the connection between the first base 101 and the second base 102.

[0037] In some embodiments, referring to Figure 4 , a plurality of slots 5 are provided on the peripheral side of the base 1. The plate member 3 is adapted to be inserted into the slots 5. The base 1 provides direct support for the plate member 3 inserted into the slots 5. After the plate member 3 is inserted into the slots 5, its degree of freedom is restricted. The movement of the plate member 3 in the horizontal and vertical directions is constrained, which helps the plate member 3 resist deformation or displacement under force, enabling the plate member 3 to bear greater vertical and horizontal loads. Even if the number of plate members 3 is reduced, it can still ensure that the lifting jig can bear the weight of the middle insulation layer, which is beneficial to reducing the self-weight of the lifting jig, and can also reduce the labor cost during production and installation and improve work efficiency. Since the plate member 3 and the base 1 are connected in a plug-in manner, it is beneficial for assembly. The plurality of slots 5 provided on the peripheral side of the base 1 can flexibly adjust the number and position of the plate members 3 according to actual needs, thereby increasing the load-bearing capacity and enhancing the flexibility and adaptability of the lifting jig.

[0038] In some embodiments, referring to Figure 3 and Figure 4 , each slot 5 is evenly distributed on the outer peripheral surface of the base 1. The evenly distributed slots 5 ensure the balanced force in all directions around the base 1, avoiding local overload. When the plate member 3 is inserted into the slots 5, the force received by the base 1 can be dispersed, improving the stability and reliability of the overall structure, and at the same time, the bearing capacity of the base 1 can be utilized to the maximum extent, enabling each plate member 3 to obtain sufficient support and avoiding waste of materials.

[0039] In some embodiments, referring to Figure 4, a plurality of first mounting holes 10 are provided on the base 1, each first mounting hole 10 penetrates through each slot 5, at least two first mounting holes 10 are provided at one slot 5, the first mounting holes 10 are used for mounting the locking member 12, the locking member 12 passes through the first mounting hole 10 and abuts against the plate member 3, fixing the plate member 3 in the slot 5. The locking member 12 located on the second base 102 also serves as a limiting block between the first base and the second base. By placing a gasket on the locking member 12, the distance between the first base 101 and the second base 102 is adjusted, so as to adjust the position of the plate member 3 in the middle heat preservation layer without changing the thickness of the first base 101 or the second base 102, facilitating the installation of the plate member 3 and the hoisting of the middle heat preservation layer.

[0040] In some embodiments, referring to Figure 4 and Figure 5 , a plurality of first mounting holes 10 are provided on the base 1, each first mounting hole 10 penetrates through each slot 5, at least two first mounting holes 10 are provided at one slot 5, the plate member 3 is formed with second mounting holes 13, the locking member 12 penetrates through the first mounting hole 10 and the second mounting hole 13, the locking member 12 is a screw or a bolt to be able to connect the base 1 and the plate member 3. The locking member 12 passes through the first mounting hole 10 and the second mounting hole 13 at the same time, so that the base 1 and the plate member 3 are fixed together, forming a rigid connection, significantly enhancing the stability and strength of the connection between the base 1 and the plate member 3. By accurately aligning and passing the locking member 12 through the first mounting hole 10 and the second mounting hole 13, the accurate position of the plate member 3 on the base 1 is ensured, so that the force on the plate member 3 is uniform, which is beneficial to the stability of the overall structure of the hoisting jig.

[0041] In order to better understand the technical solutions of the present disclosure, the following is described in combination with relatively preferred technical features.

[0042] Referring to Figure 1, the present disclosure provides a lifting fixture for a heat preservation layer in a crucible, including a base 1. The base 1 includes a first base 101 and a second base 102. The second base 102 is sleeved with the first base 101, and the second base 102 is located below the first base 101. The second base 102 is connected with a loop mechanism 4. A positioning post 8 and a boss 6 are sequentially arranged on the second base 102. The first base 101 is formed with a through hole 7. The first base 101 is connected with the second base 102 by the cooperation of the positioning post 8 and the through hole 7. An external thread is provided on the outer peripheral surface of the boss 6. The nut 2 is connected with the boss 6 through this external thread. An installation hole 9 is formed at the top of the boss 6. An internal thread is provided in the installation hole 9. The loop mechanism 4 is connected with the second base 102 through this internal thread. A plurality of slots 5 are arranged on the periphery of the base 1. The plate member 3 is adapted to be inserted into the slots 5. A plurality of plate members 3 are annularly arranged on the base 1.

Each first installation hole 10 penetrates each slot 5. At least two first installation holes 10 are provided in one slot 5. The plate member 3 is formed with a second installation hole 13. The locking member 12 penetrates the first installation hole 10 and the second installation hole 13 to be able to connect the base 1 and the plate member 3. The loop mechanism 4 is arranged in the central area of the base 1. The loop mechanism 4 includes a shaft portion 401 and a loop portion 402. The shaft portion 401 is threadedly connected with the base 1.

[0043] The above solution has the following advantages. Place the second base 102 of the lifting fixture at the central position of the middle heat preservation layer, insert the plate member 3 into the gap of the middle heat preservation layer, so that the plate member 3 is placed into the slot 5. The locking member 12 penetrates the first installation hole 10 and the second installation hole 13 to be able to connect the second base 102 and the plate member 3. After the plate member 3 is fixed, install the first base 101. The first base 101 is connected with the second base 102 by the cooperation of the positioning post 8 and the through hole 7. The nut 2 is connected with the external thread on the boss 6 to fix the first base 101. The nut 2 is a bearing locking nut. Then insert the plate member 3 into the slot 5 of the first base 101 in the middle heat preservation layer, and fix it with the locking member 12 again. Finally, install the loop mechanism 4. Connect the loop portion 402 of the loop mechanism 4 with the lifting equipment. The base 1 is set to be multi-layered, and each layer installs the plate member 3 corresponding to the level of the middle heat preservation layer, which is beneficial to ensure the stability and safety of the lifting process. The staff only needs to start the lifting equipment to lift the middle heat preservation layer, which is beneficial to the installation or disassembly of the middle heat preservation layer, reduces the labor cost, and improves the work efficiency.
