[0034] To make the objectives, technical solutions and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. However, the scope of protection of this utility model is not limited to the specific embodiments described below.

[0035] refer to Figure 1 and Figure 2 A novel multifunctional overhead crane anode guide rod clamping device includes a base 11, a vertical mounting plate 12, a drive component 21, and two gripper mechanisms. The vertical mounting plate 12 is fixedly connected to the base 11, and the two gripper mechanisms are rotatably mounted on the vertical mounting plate 12. The drive component 21 is connected to the two gripper mechanisms respectively.

[0036] The gripper mechanism includes a connecting plate 31, a gripping arm 32, and a gripper head 33. A connecting block 34 is fixedly connected to the connecting plate 31. The connecting block 34 has a connecting hole 35. The gripping arm 32 has a connecting post 36 passing through the connecting hole 35. The gripper head 33 is mounted on the end of the connecting arm away from the connecting post 36. The gripping arm 32 has a locking pin 38 that engages with the gripper head 33, securing the gripper head 33 and the gripping arm 32 to maintain stability. A pin 18 is mounted on the vertical mounting plate 12, and the connecting plate 31 is rotatably connected to the pin 18. The connecting plate 31 is connected to a driving component 21, which is a hydraulic cylinder. Connecting sleeves 22 are fixedly connected to both ends of the hydraulic cylinder. The connecting plate 31 has connecting pins 23 passing through the connecting sleeves 22, with both ends of the connecting pins 23 fixed to two connecting plates 31 respectively. The driving component 21 is connected to the connecting plate 31 via the connecting sleeve 22 and the connecting pin 23. The extension of the hydraulic cylinder causes the connecting sleeve 22 and the connecting pin 23 to rotate the connecting plate 31, thus enabling the driving component 21 to drive the gripper mechanism. The upper end of the connecting plate 31 has an inclined surface 39, with the end of the inclined surface 39 away from the pin 18 tilting downwards. This inclined surface 39 serves to avoid obstruction and increases the range of rotation when the connecting plate 31 rotates upwards. Both the connecting pin 23 and the pin 18 are located on the side of the gripper arm 32 closest to the driving component 21, and are situated inside the gripper arm 32. This makes the structure more compact, reduces the probability of collision with external equipment during movement, shortens the length of the driving component 21, reduces its weight, and decreases the load the structure needs to withstand.

[0037] A vertical mounting plate 12 is fixedly connected to a partition plate 13 located above the gripper mechanism. A spring 17 is provided between the connecting column 36 and the partition plate 13. A step 37 is fixedly connected to the connecting column 36, and the spring 17 is sleeved on the step 37. The gripper mechanism has two connecting plates 31, and the spring 17 is located between the two connecting plates 31. Placing the spring 17 between the two connecting plates 31 can protect the spring 17 from collisions with external objects, and can also provide heat insulation through the connecting plates 31, further improving the reliability of the spring 17 and achieving the advantage of a low failure rate.

[0038] The hydraulic cylinder is equipped with an inlet pipe 24 and a return pipe 25, which are connected to both ends of the hydraulic cylinder. The base 11 has two oil pipe holes 14, located at both ends of the base 11 along the length of the hydraulic cylinder, through which the inlet pipe 24 and the return pipe 25 pass. Hydraulic oil is injected into one end of the hydraulic cylinder through the inlet pipe 24 and discharged from the other end through the return pipe 25, thus enabling the hydraulic cylinder to extend and retract. When the spring 17 drives the gripper mechanism, the hydraulic cylinder extends and retracts with the rotation of the gripper mechanism, allowing the hydraulic oil inside the cylinder to flow freely within the inlet pipe 24 and the return pipe 25. The inlet pipe 24 and the return pipe 25 are respectively passed through two oil pipe holes 14. The base 11 provides support to the inlet pipe 24 and the return pipe 25 at the two oil pipe holes 14, so that the inlet pipe 24 and the return pipe 25 are closer to the center of the device. This prevents the inlet pipe 24 and the return pipe 25 from scraping against other equipment when the multi-functional crane moves the base 11, and prevents the inlet pipe 24 and the return pipe 25 from being damaged by scraping and leaking. This also prevents the hydraulic oil in the oil pipe from leaking onto the anode and being ignited, thus preventing a safety accident and improving reliability.

[0039] A heat insulation plate 15 is fixedly connected to the vertical mounting plate 12, and the heat insulation plate 15 is located below the hydraulic cylinder. The heat insulation plate 15 further reduces the heat transferred to the drive component 21 and the spring 17, thereby improving the reliability of the drive component 21 and the spring 17. Each end of the heat insulation plate 15 has a limiting surface 16 that engages with the clamping arm 32. This engagement with the clamping arm 32 by the limiting surface 16 serves to limit the clamping arm 32, preventing it from rotating downwards too much and causing the spring 17 to detach from the connecting post 36.

[0040] A support frame 41 is fixedly connected to the partition 13, and a rotating frame 42 is rotatably connected to the support frame 41. A guide plate 43 is fixedly connected to the rotating frame 42. Rotating the support frame 41 on the partition 13 causes the guide plate 43 to engage with the anode guide rod, improving the stability of the anode guide rod held by the chuck 33. The guide plate 43 is mounted on the partition 13 via the rotating frame 42 and the support frame 41, thereby enabling the partition 13 and the guide plate 43 to be supported by two vertical mounting plates 12, thus improving structural stability.

[0041] In use, the base 11 is connected to the multi-functional overhead crane. The multi-functional overhead crane moves the base 11, causing the drive component 21 to extend and open the two gripper mechanisms. The base 11 then moves the gripper mechanisms, positioning the anode guide rod between the two gripper mechanisms. The spring force of the spring 17 drives the two gripper mechanisms to approach and clamp the anode guide rod, thus enabling the multi-functional overhead crane to move the anode guide rod, achieving the function of moving the anode and completing the anode replacement operation.

[0042] This embodiment has the following advantages:

[0043] By redesigning the gripper mechanism, spring 17 can be mounted on the upper end of the gripper arm 32. The partition 13 provides support to spring 17, allowing the spring 17 to exert downward elastic force on the connecting block 34, driving the connecting block 34 and gripper arm 32 to rotate downwards. This causes the two clamps 33 to move closer together and clamp the anode guide rod. Positioning spring 17 at the end of the gripper arm 32 furthest from the clamps 33 effectively increases the distance between spring 17 and the anode of the electrolytic cell, significantly reducing the heat transferred to spring 17 when clamping the anode guide rod. This effectively lowers the temperature of spring 17 during operation, preventing spring 17 failure and reducing the failure rate, thus achieving the advantage of a lower failure rate.

[0044] The connecting post 36 is fixedly connected to the step 37, and the spring 17 is sleeved on the step 37. The connecting post 36 can position the spring 17, prevent the spring 17 from shifting, keep the spring 17 in the correct position, and reduce the number of failures caused by the misalignment of the spring 17.

[0045] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
