Multi-functional Graphite Electrode Handling Crane: High-efficiency Solution for Carbon Industry
The multi-functional graphite electrode handling crane is a furnace-loading and unloading equipment developed specifically for the carbon industry. The assembly section automatically stores graphite sheets, wraps them with film, assembles strings, and automatically switches between single and double rows of assembly. The lifting section simplifies the process, enabling the overall loading and unloading of single or double rows of multi-specification graphite electrodes and the lifting of the furnace lid. This multi-functional graphite electrode assembly and loading/unloading crane not only improves the product quality of graphite electrodes but also truly achieves high-efficiency production.
Features of Multi-functional Graphite Electrode Handling Crane
- The structure is rationally designed. The graphite electrode string assembly utilizes a main and auxiliary hydraulic propulsion system, a mobile packaging device, an automatic sheet dropping device, and a damping roller device, making it flexible and sophisticated.
- It can handle the loading and unloading of electrodes of various specifications. The lifting device is also equipped with a furnace cover hook for furnace cover lifting, meeting various production needs and offering multiple functions in one machine.
- Its complex lifting device is an innovative design, capable of loading and unloading single and double rows of graphite electrodes, as well as lifting furnace covers. The safety devices are rationally designed, accommodating both heavy lifting and delicate operation.
- The structure employs protective end seats, providing support and protection at the vulnerable ends of the graphite electrodes to prevent slippage or impact during lifting.
Lifting Device for Graphite Electrode Single and Double String
Operating Principles
First, the lower crossarm is raised via a synchronous telescopic mechanism, causing the two clamp arms of the gripper to rotate in opposite directions along the hinge point of the mounting rod, thus opening the gripper to its maximum opening degree.
Then, the gripper is aligned with the graphite electrode, positioning it at a specific height.
Next, the synchronous telescopic mechanism lowers the lower crossarm, causing the clamp arms to close simultaneously with the raising of the upper crossarm. At the same time, the speed at which the synchronous telescopic mechanism raises and lowers the lower crossarm is the same as or similar to the speed at which the crane’s overhead wire rope is retracted. This ensures that the gripper, while holding the graphite electrode, does not contact the ground or other objects.
The diameter of the graphite electrode that can be lifted is 400-800mm. If the diameter of the graphite electrode to be lifted is less than 500mm, a double-string lifting method should be used; if the diameter of the graphite electrode to be lifted is greater than 500mm, a single-string lifting method should be used.
Features of the Lifting Device
- Installing multiple clamps on the upper cross arm ensures stability during lifting, preventing graphite electrode swaying.
- The clamps can hold double strings of graphite electrodes, effectively improving the lifting efficiency of this lifting device. When holding double strings of graphite electrodes, the parallel graphite electrodes are separated by spacers, ensuring stable clamping.
- The mounting end of the clamp arm is curved, and both the mounting and clamping ends are located on the same side, increasing the clamping space between the two arms. This allows for the clamping of graphite electrodes of various diameters, improving the applicability of this lifting device.
- Wear-resistant liners on the inner side of the clamping end of the clamp arm increase friction between the clamp and the graphite electrode, enhancing the clamping capacity, ensuring stability in holding the graphite electrode, improving wear resistance, and extending service life.
