[0030] Example

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the present invention proposes a crucible-turnable and stable support, comprising two symmetrically arranged arc-shaped clamps 1. A first pressure rod 3 is rotatably mounted on the outer wall of one arc-shaped clamp 1, and a second pressure rod 4 is rotatably mounted on the outer wall of the other arc-shaped clamp 1. The first pressure rod 3 and the second pressure rod 4 are rotatably connected as one unit by a pivot shaft at their intersection. After the two pressure rods are subjected to external force, the distance between the bottom ends of the first pressure rod 3 and the second pressure rod 4 can be adjusted to facilitate clamping the crucible. Connecting parts 2 are fixedly mounted on the outer walls of the aforementioned arc-shaped clamps 1. The first pressure rod 3 and the second pressure rod 4 are rotatably mounted on the matching connecting parts 2, adopting a rotatable connection structure to facilitate subsequent crucible-turning operations. A turning handle 5 is fixedly mounted on the aforementioned connecting parts 2. When the crucible is lifted, holding the turning handle 5 and pressing it towards the ground will drive the arc-shaped clamp 1 and the crucible to rotate, facilitating the crucible-turning operation.

[0032] like Figures 1-3As shown, in order to allow the first pressure rod 3 and the second pressure rod 4 to be stably rotatably mounted on one side of the matching arc-shaped clamp 1, the connector 2 includes a connecting seat 21, which is fixedly mounted on the outer wall of the matching arc-shaped clamp 1. A connecting shaft 22 is fixedly mounted on the connecting seat 21. A limiting cap 23 is movably sleeved on one end of the connecting shaft 22 away from the connecting seat 21. The limiting cap 23 is fixedly mounted on the matching connecting shaft 22 by a locking bolt 24. A connecting sleeve 25 is movably sleeved on the connecting shaft 22. The connecting sleeve 25 is movably mounted between the matching connecting seat 21 and the limiting cap 23. The limiting cap 23 and the connecting seat 21 limit the connecting sleeve 25, ensuring that the connecting sleeve 25 can be stably rotatably mounted on the connecting shaft 22. Since the bottom ends of the first pressure rod 3 and the second pressure rod 4 are both fixedly mounted on the matching connecting sleeve 25, the first pressure rod 3 and the second pressure rod 4 can be stably rotatably mounted on the matching connector 2.

[0033] Furthermore, the bottom end of the flipping lever 5 is fixedly installed on the matching connecting seat 21. When the first pressure rod 3 and the second pressure rod 4 are lifted, the flipping lever 5 is pressed down, and the connecting shaft 22 rotates inside the connecting sleeve 25, so that the arc-shaped clamp 1 and the crucible can be flipped. At this time, the sling is connected to the first pressure rod 3 and the second pressure rod 4, and can continuously and stably provide tension to the connecting shaft 22, ensuring that the crucible can be stably suspended above the ground when flipped.

[0034] Secondly, in order to improve the stability of the limiting cap 23 in limiting the connecting sleeve 25, the threaded end of the locking bolt 24 is passed through the limiting cap 23, and its threaded end is threadedly connected to the internal thread groove chiseled at the end of the connecting shaft 22. When the connecting sleeve 25 and the connecting shaft 22 rotate relative to each other, it can prevent the end of the connecting sleeve 25 from contacting the limiting cap 23 and causing friction, thus avoiding the limiting cap 23 from rotating and effectively improving the stability of limiting the connecting sleeve 25. The limiting cap 23 and the connecting sleeve 25 can be disassembled by removing the locking bolt 24, which improves the convenience of disassembling and assembling the first pressure rod 3 and the second pressure rod 4.

[0035] like Figure 1 and Figure 4As shown, to improve the stability of the crucible during lifting, a first hand-held rod 6 is fixedly installed on the first pressure rod 3, and a second hand-held rod 7 is fixedly installed on the second pressure rod 4. The first hand-held rod 6 is positioned above the second hand-held rod 7. Lifting rings 10 are fixedly installed on both the first pressure rod 3 and the second pressure rod 4. When clamping the crucible, the operator holds the first hand-held rod 6 and the second hand-held rod 7, pushes the first hand-held rod 6 upward, and pushes the second hand-held rod 7 downward, thereby moving the two arc-shaped clamping plates 1 to the sides to increase the distance between the two arc-shaped clamping plates 1. After the distance between the clamping plates 1 is greater than the diameter of the crucible, the arc-shaped clamping plate 1 is moved downward and brought closer to the outer wall of the crucible. Then, the sling hook of the lifting equipment is put on the lifting ring 10. When the sling is stretched upward, the tops of the first pressure rod 3 and the second pressure rod 4 are both pulled upward. At this time, the bottoms of the first pressure rod 3 and the second pressure rod 4 move towards the crucible, which in turn drives the arc-shaped clamping plate 1 to move towards the crucible, ensuring that the arc-shaped clamping plate 1 can firmly clamp the crucible. During the lifting process, it can prevent the crucible from falling off the support and effectively improve the stability of the crucible during lifting.

[0036] like Figure 4 and Figure 5 As shown, during the crucible hoisting process, in order to prevent the tilting lever 5 from rotating, a limit stop bar 8 is rotatably installed on the first pressure bar 3, and a stop bar hook 9 is fixedly installed on the second pressure bar 4. By rotating the limit stop bar 8 and having one end of it engage with the stop bar hook 9, the tilting lever 5 can be limited by the limit stop bar 8, ensuring that the tilting lever 5 can be stably positioned between the first pressure bar 3 and the limit stop bar 8. Under the action of no external force, the tilting lever 5 is effectively prevented from rotating on its own.

[0037] Furthermore, when the crucible is turned over, in order to facilitate pressing down on the turning lever 5, the limiting stop 8 is rotated first. When the limiting stop 8 is rotated to the side away from the first pressing rod 3, the limiting stop 8 can be released from limiting the turning lever 5, making it easier to press down on the turning lever 5, which can then drive the dry pot to turn over.

[0038] Secondly, a hand ring 51 is fixedly installed at the top of the flip-up handrail 5. When it is necessary to press down on the flip-up handrail 5, the operator can hold the hand ring 51 to prevent the hand from slipping off the flip-up handrail 5 and improve the stability of the pressing operation. A reinforcing rod 52 is fixedly installed between the two flip-up handrails 5. The two flip-up handrails 5 are connected into one piece by the reinforcing rod 52 to ensure that the two flip-up handrails 5 form an integrated structure, which effectively increases the stability of the structure.

[0039] In this embodiment, when clamping the crucible, the operator holds the first hand lever 6 and the second hand lever 7, pushes the first hand lever 6 upward, and pushes the second hand lever 7 downward, thereby causing the two arc-shaped clamping plates 1 to move in opposite directions, which facilitates increasing the distance between the two arc-shaped clamping plates 1. When the distance between the two arc-shaped clamping plates 1 is greater than the diameter of the crucible, the support is lowered with the help of the lifting equipment to ensure that the arc-shaped clamping plates 1 can be moved down to one side of the outer wall of the crucible. The first pressure rod 3 and the second pressure rod 4 are pulled upward by the lifting equipment, thereby causing the two arc-shaped clamping plates 1 to move to one side of the crucible. When both arc-shaped clamping plates 1 are tightly attached to the outer wall of the crucible, the crucible can be firmly clamped.

[0040] Once the crucible is securely clamped, the hoisting stage begins. At this point, the slings continue to pull the first pressure bar 3 and the second pressure bar 4 upwards. When the bottom of the crucible is suspended in the air, it can be moved laterally and transported to a position above the mold. During the hoisting process, workers can hold the first hand lever 6 and the second hand lever 7 without exerting force; this provides support and reduces the likelihood of the crucible swaying during hoisting, effectively improving its stability.

[0041] After the crucible is hoisted above the mold, it enters the flipping stage. At this time, the operator rotates and adjusts the limit stop 8. When the limit stop 8 rotates away from the stop hook 9, the limitation on the flipping handle 5 is released. The operator holds the holding ring 51 and presses down on the flipping handle 5. At this time, the first pressure rod 3, the second pressure rod 4, and the connecting sleeve 25 at the ends of the two pressure rods are subjected to the upward tension provided by the sling, so that the crucible can be kept in a suspended state. The connecting shaft 22 rotates inside the connecting sleeve 25, so that the arc-shaped clamp 1 and the crucible can be flipped. Compared with the traditional crucible flipping operation, which requires the use of a spare sling to lift the bottom of the crucible, the bracket in this application can not only stably clamp the crucible, but also directly flip the crucible, effectively improving the convenience of crucible flipping.

[0042] The above specific embodiments are merely several optional embodiments of this utility model.
