Description

Technical Field

[0001] This utility model relates to the field of ultra-high power graphite electrode hoisting technology, specifically to an ultra-high power graphite electrode hoisting and transportation device. Background Technology

[0002] Ultra-high power graphite electrodes (UHP) are a type of graphite electrode and belong to the category of high-value-added products. UHP electrodes are produced using petroleum coke and needle coke as main raw materials, and coal tar pitch as a binder. The process involves a series of steps including calcination, crushing and grinding, batching and mixing, extrusion molding, roasting, pitch impregnation, graphitization, and machining. Its main characteristics are higher conductivity and better thermal stability, enabling it to withstand high-temperature and high-pressure environments and ensuring the stability and efficiency of the smelting process. Testing fixtures have become a key technological requirement for improving the standardization of battery cell testing and reducing production line debugging costs.

[0003] Publication (Announcement) No.: CN217935998U, a steelmaking anti-oxidation graphite electrode device. The existing technology has the following problems: complex structure, inability to achieve immediate clamping and use, affecting the timeliness of hoisting and use; secondly, the contact surface between the hoisting clamp and the graphite electrode is small, and during the hoisting process, due to the small force surface, it is easy to cause wear and scratches on the graphite electrode, affecting the high-quality use of the graphite electrode; secondly, during the installation of ultra-high power graphite electrodes, one-sided clamping and hoisting can facilitate the installation of ultra-high power graphite electrodes. This hoisting technology has not yet been realized in the existing technology of horizontal hoisting.

[0004] Therefore, there is a need to provide an ultra-high power graphite electrode hoisting and transportation device. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides an ultra-high power graphite electrode hoisting and transportation device, which aims to solve the technical problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-power graphite electrode hoisting and transportation device, comprising a central fixing plate, with at least three mounting openings circumferentially on the central fixing plate, a rotating shaft inside each mounting opening, the rotating shaft being connected to the middle of a hoisting force-applying plate, a guide rod connected to the upper center of the central fixing plate, a lifting rod outside the guide rod, the lifting rod being slidably connected to the guide rod and limiting its sliding, a lifting ring at the top of the lifting rod, a fixing ring at the bottom of the lifting rod, a shaft base circumferentially on the fixing ring, the shaft bases being the same number as the mounting openings and matched one by one, the top of the hoisting force-applying plate being rotatably mounted to the shaft bases, and an arc-shaped clamping plate on the side of the hoisting force-applying plate below the central fixing plate.

[0007] Preferably, stiffening plates are provided at equal intervals on the outer surface of the clamping plate, and the stiffening plates are fixedly connected to the hoisting force application plate.

[0008] Preferably, the upper circumferential part of the guide rod is uniformly provided with limiting blocks, the first hanger is configured as a cylindrical structure, the upper circumferential part of the first hanger is uniformly provided with a slot, and the limiting blocks are set inside the slot to prevent the first hanger from sliding out and to limit the vertical sliding of the first hanger.

[0009] Preferably, the hoisting force-applying plate and clamping plate are made of carbon fiber composite material.

[0010] Preferably, the hoisting force-applying plate has a bent rod structure.

[0011] In summary, this utility model provides an ultra-high power graphite electrode hoisting and transportation device. The technical effect achieved by this patent is as follows: the clamping plate clamps one side of the graphite electrode. As the lifting and clamping force increases, the graphite electrode is lifted and transported. After the hoisting is completed, the first lifting rod slides downward due to gravity, rotates and presses down the hoisting force plate, causing the circumferentially set clamping plate to unfold outward, releasing the clamped graphite electrode, and completing one hoisting operation.

[0012] A guide rod is connected to the center of the upper part of the central fixed plate. The first lifting rod slides outside the guide rod. The guide rod limits the sliding position and vertical direction of the first lifting rod, so as to achieve stable and safe hoisting and realize the vertical sliding of the first lifting rod, thus satisfying the stability and safety of hoisting.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figures 1 to 2 As shown:

[0018] This utility model is an ultra-high power graphite electrode hoisting and transportation device, which solves the problems of existing technology having complex structure, inability to achieve immediate hoisting and use; as well as small contact surface with graphite electrode hoisting, unstable hoisting, and scratches caused by high pressure;

[0019] The technology used in this patent is as follows: It includes a central fixing plate 1, with at least three mounting openings 2 circumferentially opened on the central fixing plate 1, preferably four mounting openings 2. A rotating shaft 3 is provided inside the mounting opening 2, and the rotating shaft 3 is connected to the middle of the lifting force plate 4. A guide rod 5 is connected to the upper center of the central fixing plate 1. A lifting rod 6 is provided outside the guide rod 5. The lifting rod 6 is slidably connected to the guide rod 5 and the lifting rod 6 is slidably limited. A lifting ring 7 is provided at the top of the lifting rod 6, and a fixing ring 11 is provided at the bottom of the lifting rod 6. A shaft base 12 is provided circumferentially on the fixing ring 11. Preferably, there are four shaft bases 12. The number of shaft bases 12 is the same as the number of mounting openings 2 and they are matched one by one. The top of the lifting force plate 4 is rotatably installed with the shaft base 12. An arc-shaped clamping plate 13 is provided on the side of the lifting force plate 4 located below the central fixing plate 1.

[0020] Specifically, the lifting ring 7 is used to lift the lifting rod 6. The lifting rod 6 pulls up the lifting force plate 4. The top of the lifting force plate 4 is rotatably hinged to the fixing ring 11, and the middle part of the lifting force plate 4 is rotatably installed with the rotating shaft 3. By lifting and pulling up the lifting force plate 4, the circumferentially set clamping plate 13 is closed. The clamping plate 13 clamps one side of the graphite electrode. As the lifting and clamping force increases, the graphite electrode is lifted and transported. After the lifting is completed, the lifting rod 6 slides down due to gravity, rotates and presses down the lifting force plate 4, causing the circumferentially set clamping plate 13 to unfold outward, releasing the clamped graphite electrode, and completing one lifting operation.

[0021] To achieve vertical sliding of the boom 6 and ensure the stability and safety of the hoisting, a guide rod 5 is connected to the center of the upper part of the central fixing plate 1. The boom 6 slides outside the guide rod 5, and the guide rod 5 limits the sliding position and vertical direction of the boom 6 to achieve stable and safe hoisting.

[0022] In at least one embodiment, stiffening plates 14 are provided at equal intervals on the outer surface of the clamping plate 13. The stiffening plates 14 are fixedly connected to the hoisting force application plate 4. The stiffening plates 14 are used to achieve high-strength clamping of the clamping plate 13, making the hoisting and transportation stable and safe. A wear-resistant plate 17 is provided on the inner side of the clamping plate 13 to protect the graphite electrode and protect the inner surface of the clamping plate 13 from wear.

[0023] In at least one embodiment, limit blocks 15 are evenly arranged on the upper circumference of the guide rod 5, and the lifting rod 6 is configured as a cylindrical structure. The upper circumference of the lifting rod 6 is evenly arranged with slots 16. The limit blocks 15 are arranged inside the slots 16 to prevent the lifting rod 6 from sliding out and to limit the vertical sliding of the lifting rod 6. By setting the limit blocks 15 inside the slots 16, as the lifting rod 6 slides up and down, the limit blocks 15 limit and guide the installation of the slots 16, thereby realizing the sliding of the lifting rod 6 in the vertical direction on the guide rod 5, achieving safe hoisting and stable clamping and transportation.

[0024] In at least one embodiment, to achieve high-strength use of the lifting force plate 4 and provide safe use for lifting, the lifting force plate 4 and the clamping plate 13 are made of carbon fiber composite material.

[0025] In at least one embodiment, in order to enable the lifting force plate 4 to rotate up and down and provide force bearing, the lifting force plate 4 is adopted as a bent rod structure.

[0026] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
