Utility Model Content

[0003] This application provides a crucible extraction device. It solves the problem in the prior art where the crucible is easily tilted during hoisting, leading to safety accidents. The technical solution is as follows: On one hand, a crucible extraction device is provided, the crucible extraction device comprising: Lifting components, load-bearing net, at least two spring steel plates, and multiple steel wire ropes; The at least two spring steel sheets are fixed in a cross shape to the bottom central area of ​​the carrying net, and the two opposite ends of each spring steel sheet correspond to the two opposite corners of the carrying net; when the crucible is not placed, the at least two spring steel sheets can deform to cause the central area of ​​the carrying net to arch upward synchronously; after the crucible is placed on top of the carrying net, the at least two spring steel sheets can deform under pressure to cause the central area of ​​the carrying net to arch downward synchronously. The multiple steel wire ropes correspond to the multiple corners of the carrying net, and the two ends of each steel wire rope are respectively fastened to the corner of the carrying net and the lifting component.

[0004] Optionally, the boundary shape of the carrying net is square, and there are two spring steel sheets, with the central area of ​​the two spring steel sheets fixedly connected.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a crucible extraction device according to an embodiment of this application when extracting a crucible. Figure 2 This is a schematic diagram illustrating the effect of the carrying net bag provided in this application when no crucible is placed inside. Figure 3 This is a top view of the bottom of the support net bag provided in the embodiment of this application. The crucible extraction device may include: a lifting component 100, a support net bag 200, at least two spring steel plates 300, and multiple steel wire ropes 400.

[0020] At least two spring steel sheets 300 in the crucible extraction device are cross-shaped and fixed to the bottom central region of the supporting net 200, with two opposite ends of each spring steel sheet 300 corresponding to two opposite corners of the supporting net 200. When no crucible is placed in the supporting net 200, the at least two spring steel sheets 300 can deform, causing the central region of the supporting net 200 to arch upwards synchronously; after the crucible is placed on top of the supporting net 200, the at least two spring steel sheets 300 can deform under pressure, causing the central region of the supporting net 200 to arch downwards synchronously. For example, each spring steel sheet 300 can be strip-shaped, and the thickness of each spring steel sheet 300 can range from 1.2 mm to 2 mm. The material of the spring steel sheets 300 can be a shape memory alloy made of medium carbon alloy spring steel 60Si2MnA. The at least two spring steel sheets 300 can be fixedly connected by laser welding, and the spring steel sheets 300 and the supporting net 200 can be fixedly connected by laser spot welding. It should be noted that the spring steel sheet 300 has an arc-shaped structure formed by bending in its initial state.

[0021] In the crucible extraction device, multiple steel wire ropes 400 correspond to multiple corners of the supporting net 200, with each end of the steel wire rope 400 being securely connected to a corner of the supporting net 200 and a lifting component 100, respectively. For example, each corner of the supporting net 200 has a connecting ring 201 for connecting to the end of the steel wire rope 400. Here, the connecting ring 201 can be fixed to the corner of the supporting net by welding.

[0022] In this embodiment, by placing a cooperating support net 200 and spring steel sheet 300 in the crucible A extraction device, even if the initial position of crucible A is offset, the bottom of crucible A presses down on the spring steel sheet 300. The spring steel sheet 300 deforms and stores energy, and the resulting elastic restoring force always points towards the center of the support net 200. Under the action of the restoring force, crucible A automatically slides to the center position, that is, it can automatically center without manual adjustment. When the wire rope 400 is lifted, the support net 200 is evenly stressed, and crucible A remains vertical, making it less prone to tilting when lifting crucible A, effectively ensuring production safety. In addition, crucible A automatically returns to its position after placement, shortening the operation time in high-temperature environments by more than 40%.

[0023] In summary, this application provides a crucible extraction device, which may include: a lifting component, a support net, at least two spring steel plates, and multiple steel wire ropes. By placing the cooperating support net and spring steel plates in the extraction device, even if the initial position is offset when placing the crucible, the bottom of the crucible presses down on the spring steel plates, and the spring steel plates deform and store energy. The resulting elastic restoring force always points towards the center of the support net. Under the action of the restoring force, the crucible automatically slides to the center position, that is, it can automatically center without manual adjustment. When the steel wire ropes are lifted, the support net is evenly stressed, and the crucible remains vertical, making it less prone to tilting during lifting and effectively ensuring production safety. In addition, the crucible automatically returns to its position after placement, shortening the operation time in high-temperature environments by more than 40%.

[0024] Optional, such as Figure 3 As shown, the carrying net 200 has a square boundary shape, and there are two spring steel sheets 300, with their central areas fixedly connected. In this way, the square carrying net 200 can accommodate different crucibles A.

[0025] In this application, the distances between the two ends of each spring steel sheet 300 and the two corners of the corresponding supporting net 200 are equal, and the distances between the ends of the two spring steel sheets 300 and the corners of the supporting net 200 are also equal. This further ensures that the supporting net 200 and the spring steel sheets 300 apply a uniform force to the crucible A, thereby ensuring the stable placement of the crucible A.

[0026] In the embodiments of this application, such as Figures 1-3 As shown, the inner side length L1 mm of the carrying net 200 and the outer diameter D mm of the crucible A satisfy the following relationship: L1 = K1 × D, where 1.3 ≤ K1 ≤ 1.6. Here, the inner side length L1 of the carrying net 200 can be the side length of the inner ring. Thus, the inner side length of the carrying net 200 can be determined based on the outer diameter of the crucible A.

[0027] Optionally, the length L2 mm of the spring steel sheet 300 and the inner side length L1 mm of the carrying net bag 200 satisfy the following relationship: L2 = K2 × L1, where 0.8 ≤ K2 ≤ 0.9. Thus, the length of the spring steel sheet 300 can be determined based on the inner side length L1 of the carrying net 200.

[0028] Here, the distance d between the end of the spring steel sheet 300 and the corner portion opposite to it in the carrying net bag 200 satisfies the following relationship: d = K3×L1, where 0.15≤K3≤0.2. Thus, the distance between the end of the spring steel sheet 300 and the opposite corner of the carrying net 200 can be determined based on the inner side length L1 of the carrying net 200.

[0029] The initial free state arch height h of the fixed multiple spring steel sheets 300 satisfies: h = K4 × L1, where 0.1 ≤ K4 ≤ 0.15. Thus, the initial free state arch height of the fixed multiple spring steel sheets 300 can be determined based on the inner side length L1 of the supporting net 200. It should be noted that this arch height h is the upward arch height of the central area after the multiple spring steel sheets 300 cross each other.

[0030] Optional, such as Figure 3 As shown, the support net 200 may include an annular frame 202 and a support net body 203 fixed within the annular frame 202. In this way, the annular frame 202 increases the stability and structural strength of the support net 200, ensuring safety when hoisting the crucible. For example, the support net body 203 may be a mesh structure woven from multiple stainless steel wire ropes. The annular frame 202 may be a frame structure welded from stainless steel square tubing.

[0031] In the embodiments of this application, such as Figure 1 As shown, the lifting component 100 in the crucible A extraction device may include: a universal hook 101 and multiple clamps 102. Each clamp 102 corresponds to one of multiple wire ropes 400. One end of each wire rope 400 passes over the hook of the universal hook 101 and is then securely connected to the other part of the wire rope 400 via the corresponding clamp 102. This use of the universal hook 101 allows for lifting at different angles, increasing flexibility. For example, crucible A is placed in the carrying net 200, the clamps are loosened, and the length of the wire rope 400 is adjusted to make the carrying net 200 horizontal; the clamps are tightened, and crucible A is lifted using the universal hook. During lifting, the spring steel plate 300 keeps crucible A stable and centered.

[0032] In summary, this application provides a crucible extraction device, which may include: a lifting component, a support net, at least two spring steel plates, and multiple steel wire ropes. By placing the cooperating support net and spring steel plates in the extraction device, even if the initial position is offset when placing the crucible, the bottom of the crucible presses down on the spring steel plates, and the spring steel plates deform and store energy. The resulting elastic restoring force always points towards the center of the support net. Under the action of the restoring force, the crucible automatically slides to the center position, that is, it can automatically center without manual adjustment. When the steel wire ropes are lifted, the support net is evenly stressed, and the crucible remains vertical, making it less prone to tilting during lifting and effectively ensuring production safety. In addition, the crucible automatically returns to its position after placement, shortening the operation time in high-temperature environments by more than 40%.

[0034] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
