[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2The utility model provides an embodiment: a hanger clamping device for graphite crucible production, comprising a moving beam 1 and a reversing beam 7, a plurality of concave frames 3 are fixedly connected to the bottom wall of the moving beam 1 at equal intervals, the bottom ends of the plurality of concave frames 3 are rotatably connected to a first rotating shaft 4, the left and right sides of the outer walls of the plurality of first rotating shafts 4 are rotatably connected to a plurality of first support rods 5, the bottom ends of the plurality of first support rods 5 are rotatably connected to a second rotating shaft 6, the left and right sides of the outer walls of the plurality of second rotating shafts 6 are rotatably connected to a second support rod 8, two semicircular clamps 9 are fixedly connected between the adjacent plurality of second support rods 8, and a reversing mechanism 2 is arranged in the middle of the bottom wall of the moving beam 1;

[0031] Specifically, the movable beam 1 serves as the main structure of the entire device, and a plurality of concave frames 3 can be installed. The first rotating shaft 4 at the bottom end of the concave frame 3 can enable the first support rod 5 to flexibly adjust its angle. At the same time, the second rotating shaft 6 and the second support rod 8 are used in coordination to further enhance the flexibility and clamping force of the device. When the device moves above the graphite crucible, the angles of the first support rod 5 and the second support rod 8 are adjusted so that the semicircular clamp 9 can fit tightly against the outer wall of the crucible. At this time, due to the effect of its own gravity, the semicircular clamp 9 will automatically clamp the crucible under the effect of the graphite crucible's own gravity to achieve a stable clamping effect. This clamping method is not only highly safe, but also will not cause damage to the crucible.

[0032] Reference Figure 2 and Figure 3 The reversing mechanism 2 includes a fixed column 201, a mounting slot 202 is provided in the middle of the top wall of the fixed column 201, a hydraulic column 203 is fixedly installed at the bottom end of the fixed column 201, a connecting column 204 is fixedly connected to the output end of the hydraulic column 203, a fixing ring 205 is fixedly connected to the bottom end of the connecting column 204, and the inner wall of the fixing ring 205 is rotatably connected to the middle of the outer wall of the reversing beam 7;

[0033] Specifically, the fixed column 201 is installed in the middle part of the bottom wall of the moving beam 1 to provide stable support for the entire reversing mechanism 2. Since the middle part of the bottom wall conflicts with the position of the concave frame 3, the installation gap 202 is provided to achieve the supporting effect and avoid overlapping with the position of the concave frame 3. When the hydraulic column 203 at the bottom end of the fixed column 201 performs telescopic movement, it will drive the connecting column 204 to move up and down, and the fixed ring 205 at the bottom end of the connecting column 204 is connected to the middle part of the outer wall of the reversing cross beam 7. When it is necessary to clamp the graphite crucible, the hydraulic column 203 extends and pushes the reversing cross beam 7 to move downward. The movement of the reversing cross beam 7 will drive the first support rod 5 and the second support rod 8 connected thereto to perform corresponding movement, so that the two semicircular clamps 9 are close to each other and clamp the graphite crucible. When unhooking is required, the reversing mechanism 2 can realize the unhooking operation by performing reverse operation, which not only improves the production efficiency but also reduces the difficulty of operation, providing a convenient and reliable solution for the production of graphite crucibles.

[0034] Reference Figure 2 The outer wall of the reversing beam 7 is rotatably connected with a plurality of connecting rings 10, the bottom ends of the plurality of connecting rings 10 are fixedly connected with connecting rods 11, the bottom ends of the plurality of connecting rods 11 are fixedly connected with connecting plates 12, and the top wall of the connecting plate 12 is fixedly connected with a plurality of connecting frames 13; the upper and lower ends of the outer walls of the plurality of semicircular clips 9 are fixedly connected with reinforcing keels 14; the left and right ends of the plurality of first rotating shafts 4, the left and right ends of the plurality of second rotating shafts 6 and the left and right ends of the reversing beam 7 are fixedly connected with limited blocks 15;

[0035] Specifically, the connecting ring 10, the connecting rod 11 and the connecting plate 12 together constitute a stable mechanical connection system, which can improve the stability and reliability of the entire hanger clamping device when clamping multiple graphite crucibles at the same time, and avoid displacement and shaking of multiple clamps. The reinforced keel 14 is used to enhance the structural strength of the semicircular clamp 9 to ensure that it is not easily deformed or damaged when bearing heavy loads. The limit block 15 is used to limit the movement range of the first rotating shaft 4, the second rotating shaft 6 and the reversing beam 7 to prevent structural damage or safety accidents caused by excessive rotation or movement.

[0036] Reference Figure 2 The left and right sides of the top wall of the moving beam 1 are fixedly connected with connecting pieces 16, and the tops of the two connecting pieces 16 are provided with mounting grooves 17; the inner walls of the two mounting grooves 17 are provided with iron chains 18; the tops of the two iron chains 18 are fixedly connected with lifting blocks 19;

[0037] Specifically, the connector 16 enables the sling clamping device to be firmly connected to the moving device on the top of the device, ensuring the stability and safety of the sling during movement. The mounting groove 17 provided on each connector 16 is used to accommodate and fix the iron chain 18. The iron chain 18 serves as the main lifting tool. Through the lifting block 19 connected to the top of the iron chain 18, the entire sling clamping device can be conveniently connected to the moving device, so that the sling can be conveniently lifted and moved, thereby realizing the lifting operation of the graphite crucible.

[0038] Working principle: The moving beam 1 serves as the main structure of the entire device, and multiple concave frames 3 can be installed. The first rotating shaft 4 at the bottom of the concave frame 3 can make the first support rod 5 flexibly adjust the angle. At the same time, the second rotating shaft 6 and the second support rod 8 are used in coordination to further enhance the flexibility and clamping force of the device. When the device moves to the top of the graphite crucible, the angles of the first support rod 5 and the second support rod 8 are adjusted so that the semicircular clamp 9 can fit tightly against the outer wall of the crucible. At this time, due to the effect of self-gravity, the semicircular clamp 9 will automatically clamp the crucible under the effect of the graphite crucible's own gravity.

[0039] In addition, the fixed column 201 is installed in the middle part of the bottom wall of the movable beam 1 to provide stable support for the entire reversing mechanism 2. Since the middle part of the bottom wall conflicts with the position of the concave frame 3, the installation gap 202 is provided to achieve the supporting effect and avoid overlapping with the position of the concave frame 3. When the hydraulic column 203 at the bottom end of the fixed column 201 performs telescopic movement, it will drive the connecting column 204 to move up and down. The fixed ring 205 at the bottom end of the connecting column 204 is connected to the middle part of the outer wall of the reversing beam 7. When it is necessary to clamp the graphite crucible, the hydraulic column 203 extends and pushes the reversing beam 7 to move downward. The movement of the reversing beam 7 will drive the first support rod 5 and the second support rod 8 connected thereto to perform corresponding movement, so that the two semicircular clamps 9 are close to each other and clamp the graphite crucible. When unhooking is required, the reversing mechanism 2 can perform the reverse operation to achieve the unhooking operation.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
