Description

Technical Field

[0001] This utility model relates to the field of lifting and flipping fixtures, and in particular to a lifting and flipping fixture for aluminum cathodes with a self-locking mechanism. Background Technology

[0002] Aluminum cathode lifting and turning fixtures enable efficient and precise lifting and turning of cathode carbon blocks during the production process. These fixtures are indispensable tools in aluminum cathode production, allowing for the turning of the carbon blocks to a suitable angle for furnace loading, machining, and other production operations. They can also be connected to cranes and other lifting equipment for safe and efficient transfer of cathode carbon blocks. These fixtures effectively improve the handling and processing efficiency of aluminum cathode carbon blocks in the production workshop, while ensuring production safety and increasing efficiency. They also possess strong adaptability and flexibility, and their application prospects will become increasingly broad as the aluminum electrolysis industry continues to grow.

[0003] Existing technology publication CN218988574U discloses a motor rotor lifting and turning fixture. This fixture includes a sliding beam, two clamping arms, two hinged rods, and a scissor frame. Clamping blocks are provided at the lower ends of the two clamping arms. Lifting the scissor frame causes the lower ends of the hinged rods to move closer together, thereby bringing the two clamping arms closer together, thus clamping the motor rotor to be turned and suspending it in mid-air. The clamping blocks are located at the lower ends of the clamping arms via a turning shaft, which allows the lifted motor rotor to be easily turned over and inverted, thereby reducing the difficulty of turning the motor rotor, improving motor rotor production efficiency, and reducing the workload for workers. Using this turning fixture also reduces the risk of product damage and quality problems.

[0004] However, in existing technologies, flipping fixtures typically clamp workpieces using gravity or simple mechanical structures. The greater the gravity, the greater the clamping force usually is. However, this relationship is not always stable because gravity is also affected by various factors such as the shape of the workpiece and the position of its center of gravity. Relying solely on gravity or simple mechanical structures to clamp workpieces cannot ensure accurate positioning of the workpiece during the flipping process. Due to inaccurate positioning, the workpiece is prone to slipping during the flipping process, which can not only damage the workpiece but also pose safety hazards to the equipment and operators.

[0023] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 and 2As shown, this embodiment provides an aluminum cathode lifting and flipping clamp with a self-locking mechanism, including a hollow crossbeam 1. Two movable beams 2 are slidably connected inside the crossbeam 1. The outer walls of the two movable beams 2 are rotatably connected to the legs of a scissor frame 3. Sliding holes are provided on the outer wall of the crossbeam 1. The legs of the scissor frame 3 are connected to the movable beams 2 through the sliding holes. Movable claws 4 are slidably connected to the outer sides of both ends of the crossbeam 1. Two movable claws 4 are fixed to the corresponding movable beams 2 through the sliding holes on the crossbeam 1. Clamping assemblies 6 are provided on the opposite surfaces of the two movable claws 4. Positioning assemblies 5 are provided on the top of the two movable claws 4.

[0025] like Figure 3 and 4 As shown, the positioning component 5 includes a first screw 501, which is fixed to the top of the moving claw 4. A threaded sleeve 502 is threadedly connected to the outer wall of the first screw 501. An adjusting disc 503 is fixedly connected to the outer wall of the threaded sleeve 502. The adjusting disc 503 forms a threaded structure with the first screw 501 through the threaded sleeve 502. The inner diameter of the threaded sleeve 502 matches the outer diameter of the first screw 501, and the outer wall of the first screw 501 fits snugly against the inside of the threaded sleeve 502, enhancing the connection between the adjusting disc 503 and the threaded sleeve 502. This allows the adjusting disc 503 to drive the threaded sleeve 502 to rotate on the outer wall of the first screw 501, facilitating the downward and upward movement of the threaded sleeve 502. A sliding sleeve 504 is rotatably connected to the bottom of the threaded sleeve 502, and a positioning rod 505 is fixedly connected to the outer wall of the sliding sleeve 504. A positioning groove 506 is provided at the top of the crossbeam 1. The crossbeam 1 and the positioning rod 505 form an embedded structure through the positioning groove 506. The inner diameter of the positioning groove 506 matches the outer diameter of the positioning rod 505. The bottom end of the positioning rod 505 extends into the positioning groove 506 for connection, which strengthens the connection between the crossbeam 1 and the positioning rod 505. This allows the positioning rod 505 to be fastened and installed in the positioning groove 506 and the crossbeam 1. By rotating the hand-held adjustment disc 503, the adjustment disc 503 drives the threaded sleeve 502 to rotate. The threaded sleeve 502 rotates on the outer wall of the first screw 501, causing the threaded sleeve 502 to move the bottom sliding sleeve 504. The sliding sleeve 504 then moves the positioning rods 505 on both sides into the positioning groove 506 in the crossbeam 1 for fastening and installation. This improves the fixing effect between the crossbeam 1 and the moving beam 2. It can also be used to further strengthen and improve the stability of the cathode carbon block after clamping.

[0026] In this embodiment, there are two positioning rods 505 on the sliding sleeve 504, and the two positioning rods 505 are symmetrically arranged about the perpendicular bisector of the sliding sleeve 504. Each positioning rod 505 includes a horizontal part and a vertical part connected together, and the lower end of the vertical part of the positioning rod 505 is embedded in the positioning groove 506. In this embodiment, the positioning groove 506 is in the shape of a straight line and is arranged along the length of the crossbeam 1.

[0027] like Figure 5 As shown, the clamp assembly 6 includes a side plate 601 and a clamp plate 608. The side plate 601 is fixed to the movable claw 4. A rotating shaft 602 is rotatably connected to the middle of the side plate 601. A mounting sleeve 603 is fixedly connected to the end of the rotating shaft 602 away from the movable claw 4. The mounting sleeve 603 and the side plate 601 form a rotating structure through the rotating shaft 602. The positioning of the rotating shaft 602 between the side plate 601 and the mounting sleeve 603 enhances the connection between the side plate 601 and the rotating shaft 602, allowing the mounting sleeve 603 to rotate on one side of the side plate 601 by means of the rotating shaft 602. A mounting seat 606 is provided on the side of the clamp plate 608 near the mounting sleeve 603. A second screw 605 is provided on the mounting seat 606, and the second screw 605 is threadedly connected to the mounting sleeve 603.

[0028] In this embodiment, a bolt hole 604 is provided on one side of the mounting sleeve 603; a connecting hole 607 is provided on the mounting base 606. After the connecting hole 607 and the bolt hole 604 are aligned, they are connected by bolts. By loosening the bolts, the mounting base 606 is disengaged from the mounting sleeve 603. At this time, the second screw 605 on the mounting base 606 can be rotated out of the mounting sleeve 603 by rotating the mounting base 606. This makes it easy for people to disassemble and replace the clamp plate 608. Different shapes and types of clamp plates can be used and replaced according to the needs, which improves the practicality of the clamp.

[0029] The working principle of this utility model is as follows: The scissor frame 3 can be directly lifted by a crane, causing the scissor frame 3 to extend and retract upwards, and the bottom two ends of the scissor frame 3 to move closer to the middle. This can drive the moving beam 2 inside the crossbeam 1 to move, which in turn drives the moving shells 4 on both sides to move towards the middle. The moving shells 4 then clamp the cathode carbon block using the clamping plate 608. After clamping, the adjusting disc 503 can be rotated by hand, causing the adjusting disc 503 to rotate, which in turn drives the threaded sleeve 502 to rotate. The threaded sleeve 502 rotates on the outer wall of the first screw 501, causing the threaded sleeve 502 to move the bottom sliding sleeve 504. The sliding sleeve 504 then drives the positioning rods 505 on both sides to move into the positioning grooves 506 inside the crossbeam 1 for fastening and installation. This improves the fixing effect between the crossbeam 1 and the moving beam 2, and can further reinforce and improve the clamping stability of the cathode carbon block after clamping.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
