Description

Technical Field

[0001] This application relates to the field of single crystal furnace technology, and in particular to an anti-disengagement structure and a material hanging mechanism for a material hanging mechanism. Background Technology

[0002] During the reloading process of the charging hopper, the charging mechanism typically lifts and moves the hopper within the furnace platform. The reloading process includes two steps: charging and discharging. In the charging step, the charging mechanism is hoisted, causing the hopper to slowly rise within the auxiliary chamber of the furnace platform. In the discharging step, the charging mechanism is lowered, causing the hopper to slowly descend within the auxiliary chamber of the furnace platform.

[0003] However, existing material hanging mechanisms lack anti-disengagement structures. This means that during the lowering process, if the material bucket gets stuck, the hanging mechanism will continue its lowering action, while the bucket, obstructed, will remain stationary. At this point, the hanging mechanism and the bucket will continue to move closer until they reach the hook-up line of the hanging mechanism, at which point the bucket will disengage. In this situation, the bucket is highly likely to fall, causing not only severe damage to the equipment but also potentially triggering major safety accidents such as furnace explosions, resulting in incalculable losses. Utility Model Content

[0004] In view of this, the purpose of this application is to provide an anti-disengagement structure and a material hanging mechanism for a material hanging mechanism, so as to solve the problem that the existing material hanging mechanism lacks an anti-disengagement structure, which may cause the material hopper to disengage in the auxiliary chamber.

[0005] According to a first aspect of this utility model, an anti-disengagement structure for a material hanging mechanism is provided, wherein the anti-disengagement structure for the material hanging mechanism includes: a material hanging mechanism body; a material hanging rod disposed inside the material hanging mechanism body, the material bucket being installed at the bottom of the material hanging rod, the material hanging rod being capable of moving vertically within the material hanging mechanism body; and a linkage mechanism disposed in the material hanging mechanism body, the linkage mechanism being located above the material hanging rod, the material hanging rod being able to abut against the linkage mechanism and drive the linkage mechanism to unfold during upward movement.

[0006] Preferably, the main body of the material hanging mechanism includes: a top connector connected to a driving member, the driving member driving the top connector to move in the secondary chamber; a limiting member, the top end of which is connected to the top connector, and the bottom end of which forms a hook-shaped portion, the material hanging rod being able to hang on the hook-shaped portion; and a sleeve covering the outer periphery of the material hanging rod, the top end of which is connected to the top connector.

[0007] Preferably, the linkage mechanism includes: a first link, the top end of which is pivotally connected to the top connector; a second link, disposed on the side of the first link, the top end of which is pivotally connected to the top connector; a third link, disposed between the first link and the second link, the first end of which is pivotally connected to the middle of the first link; a fourth link, disposed between the first link and the second link, the first end of which is pivotally connected to the middle of the second link; and a bottom link, the two ends of which are pivotally connected to the second ends of the third link and the fourth link, respectively.

[0008] Preferably, the top of the hanging rod is formed with a cap, which can be hung on the hook-shaped part of the limiting member.

[0009] Preferably, after the hanging rod moves upward a first preset distance, the top end of the hanging rod contacts the bottom connecting rod; when the hanging rod continues to move upward, the hanging rod drives the bottom connecting rod to move upward, causing the connecting rod mechanism to unfold; after the hanging rod moves upward a second preset distance, the first connecting rod and the second connecting rod abut against the inner wall of the auxiliary chamber.

[0010] Preferably, the material hanging rod reaches the release line when it moves upward a third preset distance, and the third preset distance is less than the second preset distance.

[0011] Preferably, the sleeve has a first strip-shaped opening extending vertically on the first and second sides, through which the first connecting rod and the second connecting rod can extend.

[0012] Preferably, there are two limiting members, which are arranged opposite to each other.

[0013] Preferably, the top end of the limiting member is pivotally connected to the top connector, and the sleeve has a second strip-shaped opening extending vertically on the third and fourth sides, through which the limiting member can extend.

[0014] According to a second aspect of the present invention, a material hanging mechanism is provided, wherein the material hanging mechanism includes the anti-disengagement structure for the material hanging mechanism as described above.

[0015] The anti-disengagement structure and hanging mechanism of this utility model embodiment have a hanging rod disposed inside the main body of the hanging mechanism. The material bucket is installed at the bottom of the hanging rod, which can move vertically within the main body of the hanging mechanism. A linkage mechanism is disposed above the hanging rod. When the material bucket encounters obstruction during its descent, the hanging rod will also stop descending simultaneously, causing the hanging rod to move upward relative to the linkage mechanism. During this upward movement, the hanging rod can abut against the linkage mechanism and drive the linkage mechanism to unfold, causing the linkage mechanism to abut against the inner wall of the auxiliary chamber, thereby preventing the linkage mechanism from continuing to descend and avoiding reaching the disengagement line. This effectively solves the problem of existing hanging mechanisms lacking an anti-disengagement structure, which could cause the material bucket to disengage within the auxiliary chamber.

[0024] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0025] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0026] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

[0031] like Figures 1 to 3 As shown, according to the first aspect of the present invention, an anti-disengagement structure for a material hanging mechanism is provided. The anti-disengagement structure for the material hanging mechanism includes a material hanging mechanism body 1, a material hanging rod 2, and a linkage mechanism 3.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the components used in the anti-disengagement structure of the material hanging mechanism and the connection relationship of the components are described in detail.

[0033] like Figures 1 to 3As shown, in this embodiment, the hanging rod 2 can be disposed inside the main body 1 of the hanging mechanism. The material bucket can be installed at the bottom of the hanging rod 2, and the hanging rod 2 can move vertically within the main body 1 of the hanging mechanism. The linkage mechanism 3 is disposed on the main body 1 of the hanging mechanism. The linkage mechanism 3 can be disposed above the hanging rod 2. When the material bucket is obstructed during its descent, the hanging rod 2 will also stop descending synchronously, causing the hanging rod 2 to move upward relative to the linkage mechanism 3. During the upward movement of the hanging rod 2 (relative to the linkage mechanism 3), the hanging rod 2 can abut against the linkage mechanism 3 and drive the linkage mechanism 3 to unfold, so that the linkage mechanism 3 abuts against the inner wall of the auxiliary chamber, thereby preventing the linkage mechanism 3 from continuing to descend, so as to avoid reaching the tripping line. This can effectively prevent the material bucket from tripping.

[0034] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the main body 1 of the material hanging mechanism may include a top connector 11, a limiting member 12, and a sleeve 13. The top connector 11 can be connected to a driving member, which can be a counterweight inside the furnace. Specifically, the top end of the top connector 11 may have a threaded hole, and the counterweight and the top connector 11 can be threaded together. The driving member drives the top connector 11 to move up and down within the auxiliary chamber. The top end of the limiting member 12 can be connected to the top connector 11. The bottom end of the limiting member 12 may form a hook-shaped portion 120. The material hanging rod 2 can be hung on the hook-shaped portion 120, allowing the main body 1 of the material hanging mechanism to drive the material bucket to move up and down. The sleeve 13 can cover the outer periphery of the material hanging rod 2 for protection and guidance. The top end of the sleeve 13 can be connected to the bottom of the top connector 11, thereby fixing the sleeve 13 to the top connector 11.

[0035] Furthermore, preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the top of the hanging rod 2 may have a cap 20. Specifically, the hanging rod 2 may be a cylindrical rod, and the cap 20 may be located at the top of the cylindrical rod. The bottom surface of the cap 20 may be a plane, so that the cap 20 can be hung on the hook-shaped portion 120 of the limiting member 12.

[0036] Further optimized, such as Figure 2 and Figure 3 As shown, in this embodiment, there can be two limiting members 12. The two limiting members 12 can be arranged opposite each other, so that the two hook-shaped parts 120 are also arranged opposite each other. When the hanging rod 2 is hung on the limiting member 12, the bottom surface of the cap 20 simultaneously abuts against the two hook-shaped parts 120, thereby enabling the main body 1 of the hanging mechanism to drive the hanging rod 2 to move up and down.

[0037] Preferred, such as Figure 2 and Figure 3 As shown, in this embodiment, the linkage mechanism 3 may include a first link 31, a second link 32, a third link 33, a fourth link 34, and a bottom link 35. The top end of the first link 31 is pivotally connected (hinged) to the bottom of the top connector 11. The second link 32 may be disposed on the side of the first link 31, and its top end is also pivotally connected to the bottom of the top connector 11. The second link 32 and the first link 31 are capable of swinging in the same plane. The third link 33 may be disposed between the first link 31 and the second link 32. The first end of the third link 33 is pivotally connected to the middle of the first link 31. The fourth link 34 is disposed between the first link 31 and the second link 32, and its first end is pivotally connected to the middle of the second link 32. The bottom link 35 is disposed between the third link 33 and the fourth link 34. The two ends of the bottom connecting rod 35 can be pivotally connected to the second ends of the third connecting rod 33 and the fourth connecting rod 34, respectively. With this configuration, when the bottom connecting rod 35 abuts against the top of the hanging rod 2, the hanging rod 2 will push the bottom connecting rod 35 upwards, thereby causing the third connecting rod 33 and the fourth connecting rod 34 to push the first connecting rod 31 and the second connecting rod 32 to pivot in opposite directions (i.e., the linkage mechanism 3 unfolds). When the first connecting rod 31 and the second connecting rod 32 abut against the inner wall of the auxiliary chamber, the first connecting rod 31 and the second connecting rod 32 cannot continue to pivot, causing the linkage mechanism 3 to be jammed, preventing the main body 1 of the hanging mechanism from continuing to move downwards, thus avoiding reaching the tripping line.

[0038] Specifically, in this embodiment, when the hanging rod 2 moves upward (i.e., the hanging rod 2 moves upward relative to the linkage mechanism 3; in reality, the hanging rod 2 should remain stationary while the linkage mechanism 3 descends) after a first preset distance, the top of the hanging rod 2 will contact the bottom connecting rod 35. In this case, when the hanging rod 2 continues to move upward, it will drive the bottom connecting rod 35 upward, causing the linkage mechanism 3 to unfold. However, when the hanging rod 2 moves upward a second preset distance, the first connecting rod 31 and the second connecting rod 32 abut against the inner wall of the auxiliary chamber, preventing the linkage mechanism 3 from further unfolding. After the linkage mechanism 3 is stuck, the main body 1 of the hanging mechanism will be unable to move downward due to the influence of the linkage mechanism 3.

[0039] In a further preferred embodiment, the material-hanging rod 2 reaches the release line when it moves upward (relative to the linkage mechanism 3) a third preset distance. At this point, the material-hanging rod 2 can disengage from the main body 1 of the material-hanging mechanism, meaning that the material-hanging rod 2 can disengage from the limiting member 12 after it descends again. Therefore, the third preset distance is less than the second preset distance, causing the main body 1 of the material-hanging mechanism to stop moving before the material-hanging rod 2 reaches the release line, thus preventing the material-hanging rod 2 from moving upward to the third preset distance.

[0040] In addition, preferred, such as Figure 1 As shown, in an embodiment, the sleeve 13 is located on a first side and a second side (which can be, for example,...). Figure 1 The left and right sides shown can be formed with a first strip opening 131 extending vertically. The width of the first strip opening 131 can be greater than the width of the first link 31 and the second link 32, so that the first link 31 and the second link 32 can extend through the first strip opening 131.

[0041] Further optimized, such as Figures 1 to 3 As shown, in this embodiment, the top end of the limiting member 12 can be pivotally connected (or hinged) to the bottom end of the top connecting member 11, allowing the two limiting members 12 to pivot away from each other to remove the hanging rod 2 from the hanging mechanism body 1. The sleeve 13 is located on the third and fourth sides (which can be as follows). Figure 1 The front and rear sides (shown) can be formed with a second strip opening 132 extending vertically. The width of the second strip opening 132 can be greater than the width of the limiting member 12, so that the limiting member 12 can extend through the second strip opening 132.

[0042] In addition, such as Figures 1 to 3 As shown, according to a second aspect of the present invention, a material hanging mechanism is provided, the material hanging mechanism including the anti-disengagement structure for the material hanging mechanism as described above.

[0043] During operation, when the material bucket encounters obstruction during its descent, the hanging rod 2 will simultaneously stop descending, causing it to move upward relative to the linkage mechanism 3. As the hanging rod 2 moves upward (relative to the linkage mechanism 3), it engages with the linkage mechanism 3, driving it to unfold and contact the inner wall of the auxiliary chamber, thus preventing further descent and avoiding reaching the tripping line. This effectively prevents the material bucket from disengaging. If the material bucket is not obstructed during descent, the material bucket refilling process can be completed. Afterward, the hanging mechanism and material bucket can be removed from the auxiliary chamber. Since the linkage mechanism 3 is no longer restricted by the auxiliary chamber and can fully unfold, the hanging rod 2 can rise to the tripping line, allowing the material bucket to be disassembled.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
