DETAILED DESCRIPTION

[0027] 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.

[0028] Example

[0029] A tool for transporting and pre-installing a graphite electrode joint, comprising a hoisting assembly, a connecting assembly and a flipping assembly; the connecting assembly is connected to the bottom of the hoisting assembly, and the flipping assembly is connected to one side of the connecting assembly;

[0030] At least two groups of lifting components are provided, and the lifting components include a lifting device, a lifting rope 1, a lifting ring 2 and a lifting lug 3; the lifting rope 1 is connected to the lifting device, the lifting ring 2 is connected to the bottom of the lifting rope 1, and the lifting lug 3 is movably connected to the lifting ring 2; a connecting tube 5 is fixedly connected to the bottom of the lifting lug 3; the connecting component includes a connecting frame 7 and a connecting rod 4, and the two sides of the bottom of the connecting frame 7 are respectively fixedly connected with installation tubes 6; there are two connecting rods 4, and the two connecting rods 4 are respectively rotatably connected to the installation tube 6, and the two connecting rods 4 are also respectively rotatably connected to the connecting tube 5. It should be noted that since the lifting rope 1 is relatively long as a whole, the lifting device is not shown in the figure. It is easy to understand that the lifting device is located above the lifting rope 1.

[0031] The flip assembly includes a main rod 9, a support rod 8 and a support member 10, wherein the main rod 9 is fixedly connected to the connecting frame 7; the support rod 8 is arranged at an angle, one end of the support rod 8 is fixedly connected to the connecting frame 7, and the other end is connected to the support member 10; the support member 10 is provided with an arc-shaped contact surface matching the graphite electrode joint 14 on one side close to the graphite electrode joint 14.

[0032] First of all, it should be noted that there are paste filling holes on both sides of the graphite electrode joint 14, which are used to inject conductive paste into the electrode connection. When installing the graphite electrode joint 14, first pass the connecting rod 4 through the installation tube 6 and the connecting tube 5 in sequence, and then insert the connecting rod 4 into the paste filling hole of the graphite electrode joint 14. Start the lifting equipment, and the lifting equipment pulls the connecting rod 4 through the lifting rope 1, the lifting ring 2 and the lifting ear 3, and then pulls up the graphite electrode joint 14 as a whole through the connecting rod 4. Since the connecting frame 7 is an integral structure, the connecting frame 7 can effectively prevent the graphite electrode joint 14 from tipping over during the pulling process. The pulled-up graphite electrode joint 14 is in a vertical shape. The graphite electrode joint 14 needs to be inserted into the graphite electrode 13 and the graphite electrode joint 14 needs to be flipped 90°. At this time, by pulling the main rod 9 downward, the main rod 9 drives the connecting frame 7 to rotate, and the connecting frame 7 drives the support rod 8 to rotate. After the support member 10 connected to the support rod 8 contacts the graphite electrode joint 14, the graphite electrode joint 14 will be supported and the graphite electrode joint 14 will rotate together. In this way, after the graphite electrode joint 14 is rotated 90°, the graphite electrode joint 14 can be installed in the graphite electrode 13. The main rod 9, the connecting frame 7 and the support rod 8 form a lever structure, which can easily flip the graphite electrode joint 14. The rear end of the main rod 9 can also be equipped with an extension rod to increase the force arm, which is further convenient for flipping the graphite electrode joint. The arc-shaped contact surface of the support member 10 can increase the contact area with the graphite electrode joint 14, thereby effectively protecting the thread on the surface of the graphite electrode joint 14, and ensuring that the graphite electrode joint 14 can be installed smoothly. After the graphite electrode connector 14 is installed, the connecting rod 4 is pulled out, and the conductive paste is poured into the paste-filling hole.

[0033] In a preferred embodiment, the lifting device is an electric hoist. The electric hoist has the advantages of strong lifting capacity and precise control. For example, a PA200 electric hoist can be used.

[0034] In a preferred embodiment, a bayonet 11 is provided near the top of the lifting ring 2. The lifting lug 3 is connected to the lifting ring 2 after passing through the bayonet 11. The lifting lug 3 and the lifting ring 2 are detachably connected through the bayonet 11. When hoisting a relatively large graphite electrode joint 14, a thicker connecting rod 4 needs to be used in conjunction with it. In order to match the thicker connecting rod 4, a connecting tube 5 with a larger diameter needs to be used, so the lifting lug 3 needs to be replaced. The design of the bayonet 11 facilitates the rapid replacement of the lifting lug 3.

[0035] In a preferred embodiment, the connecting rod 4 is made of alloy steel, such as HSLA steel. The connecting rod 4 is a major load-bearing component, and bending of the connecting rod 4 will cause the graphite joint to slip, so a connecting rod 4 with high strength is required.

[0036] In a preferred embodiment, the connecting frame 7 includes a support plate 702 and a foot plate 701, and the support plate 702 is connected to the foot plate 701 by bolts. The design of the bolt connection makes the support plate 702 and the foot plate 701 detachably connected. Through this design, the position of the foot plate 701 can be adjusted, so that the connecting frame 7 can adapt to a variety of different graphite electrode 13 connectors. Furthermore, a plurality of evenly spaced bolt holes are provided on both sides of the support plate 702. The provision of multiple bolt holes can facilitate the adjustment of the position of the foot plate 701. Thus, the structure of the utility model can adapt to different graphite electrode connectors 14.

[0037] In a preferred embodiment, a mounting block 12 is connected to the support rod 8 at one side away from the connecting frame 7 by bolts, and the support member 10 is fixedly connected to the mounting block 12, and the support member 10 is connected to the support rod through the mounting block 12. This design allows the support member 10 to be detachably connected to the support rod 8, thereby realizing replacement of different support members 10 according to different graphite electrode joints 14, and effectively protecting the graphite electrode joints 14.

[0038] In a preferred embodiment, a protective plate made of rubber material is provided on the contact surface of the support member 10. The protective plate made of rubber material is relatively soft and can effectively protect the threads on the graphite electrode joint 14. Through this design, the threads on the graphite electrode joint 14 are prevented from being damaged by the support member 10.

[0039] In a preferred embodiment, the main rod 9 is a hollow structure. The main rod 9 with a hollow structure can reduce the weight of the entire tool.
