Description

Technical Field

[0001] The utility model relates to a tool, in particular to a tool for quickly fishing out electrodes. Background Art

[0002] The main application areas of graphite electrodes are as conductive materials and heating metals in electric arc furnaces or refining furnaces. The electrodes are easily broken due to high temperature, high stress and smoke damage during the production process. After the electrode is broken, the operator needs to stop the furnace for processing and salvage. The general specifications of graphite electrodes are 400-700mm in diameter, and there are even large-sized graphite electrodes of 800mm. The speed of salvaging the broken electrode directly determines the impact on production.

[0003] At present, the electrode clamp used in the refining furnace to handle the broken electrode accident has a structure such as "A device for quickly salvaging the electrode of the ore-heating furnace" (CN201420314728.7), which is movably connected to a clamping device through a lifting ring, and the clamping device is a clamp with a pin shaft. During operation, the clamp is first lowered and dropped onto the broken electrode. The operator needs to use a wooden stick to open the upper part of the electrode clamp, so that the bottom is opened, so that the opening is larger than the diameter of the electrode currently in use, and then command the overhead crane to lift the electrode clamp. During the lifting process, personnel need to cooperate with the overhead crane to slowly lift it. In this process, the wooden stick often falls off, resulting in the readjustment of the clamp. Once the personnel fail to evade in time, safety accidents are more likely to occur, and the efficiency of handling the electrode in the accident is affected, which is not conducive to the organization of production on site and the safety of personnel.

[0004] Therefore, there is an urgent need for a tool that is easy to operate, quick and efficient in salvaging and has high working efficiency. Utility Model Content

[0019] like Figure 1 As shown, the utility model is a tool for quickly fishing out electrodes.

[0020] In embodiment 1, it includes: a clamp arm, a rotating shaft 5 and a support rod 3.

[0021] There are two clamp arms, each of which includes a fixedly connected straight plate 4 and a curved arm 6. The lower parts of the two straight plates 4 are rotatably connected by a rotating shaft 5, and the two clamp arms form an X shape. There is a lifting hole 1 at the upper end of the straight plate 4, and the lifting hole 1 is connected by a chain to facilitate the overhead crane to lift and lower.

[0022] A support rod 3 is hinged on the inner side of the straight plate 4 on one side, and a stopper 2 is installed on the inner side of the straight plate 4 on the other side. The distance from the hinge point of the support rod 3 to the rotation axis 5 is less than the distance from the installation point of the stopper 2 to the rotation axis 5, and the distance from the hinge point of the support rod 3 to the rotation axis 5 is greater than the length of the support rod 3. The free end of the support rod 3 can be blocked by the stopper 2. In the optimization scheme, the support rod 3 is T-shaped, and the cross bar at the free end is more easily blocked by the stopper 2.

[0023] When in use, the free end of the support rod 3 is pressed against the block 2. At this time, the support rod 3 is supported by force to ensure that the bottom opening of the curved arm 6 has a certain opening. The lifting hole 1 is connected by a chain, and the auxiliary hook of the overhead crane hooks the chain, and the utility model is dropped above the broken electrode and then slowly lowered. When the curved arm 6 contacts the electrode, due to the force support, the bottom opening of the curved arm 6 is opened by the electrode, and then the opening angle of the upper end of the straight plate 4 is also increased, and the force on the support rod 3 disappears. Due to gravity, the support rod 3 rotates and fits to the inside of the straight plate 4. After touching the bottom, the overhead crane is commanded to lift the auxiliary hook. At this time, the function of the support rod 3 is lost, the opening angle of the upper end of the straight plate 4 becomes smaller, and the bottom opening of the curved arm 6 clamps the electrode, and the broken electrode is lifted out of the ladle for processing.

[0024] Embodiment 2 is optimized on the basis of embodiment 1, the stopper 2 is connected to the inner side of the straight plate 4 by bolts, and the inner side of the straight plate 4 has multiple screw holes for connecting bolts, so as to facilitate the rapid adjustment of the original opening of the bottom opening of the crank arm 6 according to the diameter of the graphite electrode (400-800mm).

[0025] The utility model effectively ensures the opening of the bottom of the clamp arm through the force support of the support rod 3; it can ensure the success rate of the operation in one time and avoid the waste of time for secondary salvage; at the same time, it protects the safety of the operators who salvage the broken electrode and avoids the occurrence of safety accidents, while reducing the time for salvaging the broken electrode and improving the operation efficiency.

[0026] It should be noted that matters not described in detail in this embodiment are well-known technologies in the art.

[0027] The above description is only for the purpose of describing the present invention in detail for the specific implementation purpose of the present invention. For those skilled in the art, various obvious changes made to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
