Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0030] Please refer to the attached Figure 1 - attached Figure 2 As an embodiment provided by the present utility model: a new type of graphite crucible lifting device, including a top plate 6. Rotating shafts 1 are fixedly connected to the left and right sides of the bottom end of the top plate 6. The bottom ends of the rotating shafts 1 are rotatably connected to inclined plates 2. The bottom ends of the inclined plates 2 are rotatably connected to inclined plate 1 3. The bottom end of the inclined plate 1 3 is rotatably connected to inclined plate 3 11. The bottom end of the inclined plate 3 11 is rotatably connected to a T-shaped plate 15. Limiting sliding plates 16 are fixedly connected to the left and right sides of the outer wall of the T-shaped plate 15. An L-shaped clamping plate 17 is fixedly connected to the bottom end of the T-shaped plate 15. A C-shaped plate 18 is fixedly connected to the inner bottom end of the L-shaped clamping plate 17. A long plate 1 is arranged at the bottom end of the top plate 6. Limiting grooves 14 are opened on the left and right sides inside the long plate 1. A falling prevention mechanism 2 is arranged on the outer wall of the long plate 1. The function of the falling prevention mechanism 2 is to prevent the debris falling from the high-temperature graphite crucible from contacting the operator. Support columns 8 are fixedly connected to the left and right sides of the top end of the top plate 6. A hanging ring 10 is fixedly connected to the top end of the support column 8;
[0031] Specifically, rotating shafts 1 are fixedly connected to the left and right sides of the bottom end of the top plate 6. These two rotating shafts 1 are not only the connection points between the top plate 6 and the components below, but also the key to realizing the rotation of the components below. The design of the inclined plates 2 enables the entire structure to maintain a certain inclination angle during rotation, thereby realizing a specific movement trajectory. The bottom end of the inclined plate 2 is rotatably connected to the inclined plate 1 3. This connection method enables the inclined plate 1 3 and the inclined plate 2 to rotate relative to each other, further increasing the flexibility of the structure. This connection method enables the T-shaped plate 15 to move as the inclined plate 3 11 rotates, thereby realizing the position adjustment of the T-shaped plate 15 and its connected components. This is a component for clamping or fixing an object. A C-shaped plate 18 is also fixedly connected to the inner bottom end of the L-shaped clamping plate 17. The design of the C-shaped plate 18 may be used to further enhance the clamping force or provide additional support.
[0032] Please refer to the attached Figure 3, the anti-falling mechanism 2 includes a telescopic rod 205. The inner side of the telescopic rod 205 is fixedly connected to the front and rear sides of the outer wall of the long plate 1. The output end of the telescopic rod 205 is fixedly connected with an L-shaped plate 206. The inner bottom end of the L-shaped plate 206 is fixedly connected with a telescopic plate 201. The bottom end of the telescopic plate 201 is fixedly connected with a closing plate 202. The middle parts of the inner sides of the closing plates 202 are fixedly connected with magnetic attraction blocks 204. The bottom ends of the closing plates 202 are fixedly connected with rubber blocks 203. The inner sides of the two magnetic attraction blocks 204 are attracted to each other;
[0033] Specifically, the telescopic rod 205 is a core component in this mechanical structure, and its inner side is fixedly connected to the front and rear sides of the outer wall of the long plate 1. This design ensures the stability and reliability of the telescopic rod 205, and at the same time makes the whole structure more compact and orderly. The design of the telescopic plate 201 enables it to be telescopically adjusted according to needs, so as to adapt to different working scenarios and requirements. This design greatly improves the practicability and adaptability of the whole structure, and improves the sealing performance and stability of the structure. At the same time, the magnetic attraction blocks 204 also make the opening and closing process of the closing plates 202 smoother and easier, and the rubber blocks 203 can play a role in buffering and protection, preventing the closing plates 202 from being damaged or scratched.
[0034] Please refer to the attached Figure 1 -attached Figure 3 , both the left and right sides of the bottom end of the top plate 6 are fixedly connected with lighting lamps 7. The inner side of the hanging ring 10 is fitted with a hook 9. One side of the outer wall of the L-shaped plate 206 is fixedly connected with a fluorescent plate 12. The two fluorescent plates 12 are fixedly connected at the same horizontal height. The middle part of the front side of the front closing plate 202 is fixedly connected with a storage battery 13. The storage battery 13 supplies power to the telescopic rod 205 and the lighting lamps 7 respectively. The inner side of the limit groove 14 is slidably connected with the outer wall of the limit sliding plate 16. The inner sides of the C-shaped plates 18 are fixedly connected with anti-slip pads 19;
[0035] Specifically, lighting lamps 7 are carefully installed on both the left and right sides of the bottom end of the top plate 6. These lighting lamps 7 can not only provide bright light, ensuring that users can clearly see the inside or surrounding conditions of the mechanical structure in low-light or night environments. The hanging ring 10 is cleverly designed at an appropriate position of the mechanical structure, and its inner side is fitted with a hook 9. This design enables users to hang other items or tools on the hanging ring 10 through the hook 9, thus realizing convenient storage and access. The hanging ring 10 and the hook 9 are made of strong and durable materials and can bear a certain weight, ensuring the safety and stability of the mounted items. The two fluorescent plates 12 are accurately installed at the same horizontal height to ensure in low-light or night environments.
[0036] Working principle: When it is necessary to lift the graphite crucible, first, the graphite crucible to be lifted is clamped between the adjacencies of the C-shaped plate 18. With the cooperation of the T-shaped plate 15 fixedly connected to the L-shaped clamping plate 17 and the limit sliding plate 16, the limit sliding plate 16 slides along the inner side of the limit groove 14 opened on the long plate 1. After that, when the top plate 6 is pulled upward in cooperation with the crane, the second inclined plate 4 rotatably connected to the outer wall of the first rotating shaft 5 cooperates with the first inclined plate 3, the third inclined plate 11, and the top of the T-shaped plate 15 to rotate. Due to the inertia of the upward pulling of the top plate 6, the third inclined plate 11 cooperates with the limit sliding plate 16 to relatively slide along the inner side of the limit groove 14, so that the two C-shaped plates 18 can clamp and move the graphite crucible:
[0037] After that, during the movement of the graphite crucible, slag will fall off the surface, and the temperature of the slag surface is relatively high, which is somewhat dangerous during the falling process. At this time, the telescopic rod 205 is started, and the L-shaped plate 206 is pushed outward in cooperation. Then, according to the length of the graphite crucible, the telescopic plate 201 is telescoped downward to the bottom. Subsequently, in cooperation with the contraction of the telescopic rod 205, the two closing plates 202 are fitted with the magnetic attraction blocks 204 to form a falling prevention plate.
[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
