Description
Technical Field
[0001] This application relates to the field of auxiliary equipment for anode carbon block processing, and in particular to a remote-controlled automatic flipping fixture for prebaked anodes. Background Technology
[0002] Prebaked anode carbon blocks are a core consumable in aluminum electrolysis production. They primarily act as anode conductors in aluminum electrolysis cells, carrying current and participating in electrochemical reactions during electrolysis. During electrolysis, the carbon blocks combine with oxygen in the electrolyte to generate carbon dioxide, continuously creating a chemical environment for aluminum deposition. Prebaked anode carbon blocks are typically made from petroleum coke and pitch coke as main raw materials, through multiple processes including batching, mixing, molding, and calcination. In the anode carbon block production and testing stage, sampling is required. Before sampling, the anode carbon blocks must be rotated to a specified angle (90° or 180°) so that personnel can obtain samples that meet testing requirements. Currently, the industry commonly uses ordinary clamps to fix the anode carbon blocks, and the rotation process relies on manual operation or external large lifting equipment for assistance.
[0003] Existing flipping operations have significant drawbacks. Most fixtures do not have a flipping function themselves, requiring ground staff to manually pry up heavy carbon blocks weighing up to 1 ton using tools such as crowbars. This is not only extremely labor-intensive but also poses a high safety risk and can easily cause personal injury. In addition, manual flipping is time-consuming, directly affecting the efficiency of sampling operations. On the other hand, the few fixtures that integrate flipping mechanisms mostly rely on large hydraulic systems or complex external power sources, resulting in complex structures, high manufacturing costs, inflexible operation, and limited applicability to anodes of different heights. Utility Model Content
[0004] This device provides a remote-controlled automatic flipping fixture for prebaked anodes, the specific implementation of which is as follows: A remote-controlled automatic flipping fixture for prebaked anodes includes: The mounting base and the cross-arm structure mounted on the mounting base, with the two arms of the cross-arm structure having length adjustment rods and rotators facing each other at opposite ends; The length adjustment rod is threaded to the end of the clamp arm of the cross clamp arm structure, and its end is rotatably connected to a second side pressure plate; The rotator includes a rotary motor installed at the end of the clamping arm of the cross clamping arm structure. The output end of the rotary motor is rotatably connected to the first side pressure plate via a drive shaft. A hook is provided at the top of the cross clamping arm structure. The charcoal block is placed below the mounting base and between the two clamping arms of the cross clamping arm structure. The hook is pulled up to clamp and position the charcoal block, and the rotator automatically flips the charcoal block.
[0005] Based on the above technical solution, the length adjustment rod and the rotator are combined to act on both ends of the charcoal block and form a rotation drive unit. The rotary motor in the rotator is a low-voltage geared motor. The output shaft of the low-voltage geared motor is connected to the pressure plate by a coupling to drive the entire clamped charcoal block to rotate.
[0006] Preferably, the cross-arm structure includes a pair of main clamping arms that are hinged to each other, and an L-shaped clamping arm is hinged to the other end of the two main clamping arms; the two L-shaped clamping arms are arranged in an X-shape and are respectively rotatably connected to the mounting base.
[0007] Preferably, a lifting plate is vertically slidable on the inner side of the mounting base, and a pull plate with a pull hole is provided on the top of the lifting plate; an arc-shaped pull hook is provided at the bottom of the cross-arm structure, and the pull hook is actively connected to the pull plate downward.
[0008] Based on the above technical solution, the upper part of the cross clamping arm structure is provided with a hook for connecting with the overhead crane. The main clamping arm is opened and closed by the lifting drive of the overhead crane to clamp or release the anode carbon block. The bottom of the hook is arc-shaped. When the hook descends relative to the lifting plate, the hook can disengage from the pull hole of the plate. When the hook is lifted, the hook can hook into the pull hole of the plate.
[0009] Preferably, it also includes a controller and a lifter located on the top of the lifting plate. The lifter includes a lifting motor and at least two lead screw lifting seats arranged in parallel. The output end of the lifting motor is connected to each lead screw lifting seat through a connecting shaft. The lifting rod is vertically slidably disposed in the lead screw lifting seat. The lifting rod has an external thread along its length direction, and each lifting rod meshes with a gear on the connecting shaft.
[0010] Preferably, the signal input terminal of the controller is electrically connected to a remote controller, and the signal output terminal of the controller is electrically connected to the lifting motor and the rotating motor respectively.
[0011] Preferably, it also includes a battery pack mounted on the mounting base, the battery pack being electrically connected to the controller, the lifting motor and the rotating motor.
[0012] Based on the above technical solution, the remote control is a wireless remote control transmitter independent of the clamp, held by the operator, used to send a flip signal to the remote control receiver; the battery pack is a lithium-ion battery pack, which can provide independent power for the rotary motor, lifting motor and controller. The battery pack is also equipped with a charging interface for easy charging and maintenance. The lifting motor is a DC geared motor with a rated voltage of 48V, which is safe and easy to drive by battery; the controller and battery pack can be integrated into a waterproof and dustproof enclosure to adapt to high temperature and dusty environments, and the controller and remote control are wirelessly connected through the remote control receiver.
[0013] The operator holds a wireless remote control. When it's necessary to flip the carbon block, they adjust the lifting mechanism using the remote control buttons to adjust the height of the clamp to match the height of the carbon block and center the rotator and length adjustment rod around it. After the overhead crane lifts the clamp and carbon block, the operator presses the remote control from a safe distance to raise the positioning plate to a position close to the mounting base, allowing the anode carbon block room to rotate. Then, pressing the "forward" or "reverse" button on the remote control sends a signal to the receiver in the battery pack and remote control system box. The controller then starts the rotator, rotating the carbon block to the desired angle (e.g., 90° or 180°). Releasing the button stops all motors and locks them in place. Placing the carbon block on the ground completes the flipping process.
[0014] Preferably, the rotary motor is vertically mounted on the outside of the L-shaped clamping arm, and the output end of the rotary motor is connected to the drive shaft through a gearbox.
[0015] Preferably, the length adjusting rod includes a screw threaded to an L-shaped clamping arm, one end of which is connected to a rotating handle, and the other end is rotatably connected to a second side pressure plate via a threaded sleeve.
[0016] Preferably, the second side pressure plate and the threaded sleeve, and the drive shaft and the first side pressure plate are all connected by universal joints.
[0017] Based on the above technical solutions, the length adjustment rod can be manually fine-tuned according to the actual length of the charcoal block, so that the second side pressure plate and the first side pressure plate can stably clamp the two ends of the charcoal block; and both the second side pressure plate and the first side pressure plate are designed with universal joints, which can further optimize the clamping effect and reduce the clamping deviation of the charcoal block.
[0018] In summary, this application includes the following beneficial technical effects: 1. This utility model achieves remote-controlled automatic flipping by setting a controller, length adjustment rod and rotator at the front end of the cross clamping arm structure, which completely avoids the safety risks caused by manually prying the carbon block at close range, greatly improves the safety of operation, and the flipping process is fast and accurate, which improves the overall work efficiency. 2. This utility model, by setting a positioning plate and a lifting device, rotates and centers the charcoal block before flipping it over. By adjusting the height of the positioning plate, it can achieve compatible flipping of charcoal blocks of different heights. 3. This utility model has a simple structure. Based on the existing mature fixture, only a motor, battery and controller are added. The modification cost is low and it is easy to promote and implement. Operators can easily control the flipping action from a safe distance by holding a remote control. The operation experience is good and the labor intensity is low. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-7This application will be described in further detail.
[0024] This application discloses a remote-controlled automatic flipping fixture for prebaked anodes.
[0025] Example 1 Reference Figures 1 to 2 and Figures 5 to 7 This embodiment discloses a prebaked anode remote-controlled automatic flipping fixture, including a mounting base 4 and a cross clamping arm structure 5 mounted on the mounting base 4. The two clamping arm ends of the cross clamping arm structure 5 are respectively provided with a length adjusting rod 1 and a rotator 6 facing each other. The length adjusting rod 1 is threaded to the clamping arm end of the cross clamping arm structure 5, and its end is rotatably connected to a second side pressure plate 104.
[0026] The rotator 6 includes a rotary motor 603 installed at the end of the clamping arm of the cross clamping arm structure 5. The output end of the rotary motor 603 is rotatably connected to the first side pressure plate 601 via a transmission shaft 602. The top of the cross clamping arm structure 5 is provided with an upper pull arm 502. The charcoal block 10 is placed below the mounting base 4 and between the two clamping arms of the cross clamping arm structure 5. The upper pull arm 502 is pulled up to clamp and position the charcoal block 10. The rotator 6 automatically flips the charcoal block 10.
[0027] The cross-arm structure 5 includes a pair of main clamping arms 501 that are hinged to each other. The other end of the two main clamping arms 501 is hinged to an L-shaped clamping arm 503. The two L-shaped clamping arms 503 are arranged in an X-shape and are rotatably connected to the mounting base 4. In this structure, a lifting plate 401 is vertically slidably provided on the inner side of the mounting base 4. The top of the lifting plate 401 is provided with a pull plate 402 with a pull hole. The bottom of the cross-arm structure 5 is provided with an arc-shaped pull hook 7, and the pull hook 7 is flexibly connected to the pull plate 402 downward. A rotary motor 603 is vertically installed on the outer side of the L-shaped clamping arm 503. The output end of the rotary motor 603 is connected to the drive shaft 602 through a gearbox 604. The top of the cross-arm structure 5 is provided with a hook 502.
[0028] The length adjustment rod 1 includes a screw 102 threaded onto an L-shaped clamp arm 503. One end of the screw 102 is connected to a rotating handle 101, and the other end is rotatably connected to a second side pressure plate 104 via a threaded sleeve 103. The second side pressure plate 104 and the threaded sleeve 103, as well as the drive shaft 602 and the first side pressure plate 601, are all rotatably connected by universal joints.
[0029] Example 2 Reference Figures 1 to 6This embodiment also discloses a prebaked anode remote-controlled automatic flipping fixture, which includes a controller 2 and a lifter 8 located on the top of the lifting plate 401, as well as a battery pack installed on the mounting base 4. The battery pack is electrically connected to the controller 2, the lifting motor 801 and the rotary motor 603. This structure uses a battery pack for power supply, without relying on an overhead crane or a complex hydraulic system and an external power supply. The structure is independent, easy to modify, and can be widely used in different types of fixtures.
[0030] The lifting device 8 includes a lifting motor 801 and at least two lead screw lifting seats 803 arranged in parallel. The output end of the lifting motor 801 is connected to each lead screw lifting seat 803 through a connecting shaft 802. In this structure, the lead screw lifting seat 803 is vertically slidably mounted on the lifting rod 804. The lifting rod 804 has an external thread along its length, and each lifting rod 804 meshes with a gear on the connecting shaft 802. The bottom end of each lifting rod 804 is connected to a positioning pressure plate 3. The signal input end of the controller 2 is electrically connected to a remote controller 9, and the signal output end of the controller 2 is electrically connected to the lifting motor 801 and the rotary motor 603 respectively.
[0031] The specific implementation process is as follows: Before the charcoal block is flipped, the overhead crane connects to the hook 502 and lowers the crane so that the positioning plate 3 abuts against the upper end of the charcoal block 10. At this time, the pull hook 7 disengages from the pull plate 402, and the lifting plate 401 and the positioning plate 3 are at the lowest position of the mounting base 4. Based on visual inspection, the operator changes the abutment height of the positioning plate 3 with the help of the controller 2 and the lifting motor 801 so that the second side plate 104 is at the center position of the side of the charcoal block 10. During the flipping process, the overhead crane pulls the hook 502, causing the two sides of the cross clamping arm structure 5 to clamp the carbon block 10 with the help of the first side pressure plate 601 and the second side pressure plate 104. Simultaneously, the hook 7 hooks the pull plate 402, raising the lifting plate 401 and the positioning pressure plate 3, thereby leaving a flipping gap between the positioning pressure plate 3 and the top of the carbon block 10. After the carbon block 10 is lifted, a flipping gap is also left between its bottom and the ground. The controller 2 controls the rotary motor 603 to start, completing the automatic flipping of the carbon block 10. The rotator 6 contacts the anode carbon block 10 through the transmission shaft 602, which can drive the carbon block 10 to rotate, thereby realizing the flipping of the carbon block at any angle.
[0032] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
