Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis technology, specifically relating to an anode guide rod anti-fall device. Background Technology

[0002] In the aluminum electrolysis production process, anodes need to be replaced promptly after wear and tear. During replacement, the multi-functional unit's clamp assembly relies on hydraulic cylinders and locking springs to clamp the anode's guide rod, remove the anode, and move it to the appropriate position for replacement. The clamp assembly ensures the safe transport of the anode during anode replacement and transport. However, locking springs can fail or fatigue, hooks and anode cylinders can wear and deform, and human error such as accidental switch activation or failure to confirm locking significantly increases the risk of anodes falling during anode replacement and transport. Once a fall occurs, it not only directly threatens the safety of on-site personnel but may also cause secondary disasters such as equipment damage. Existing protection solutions rely excessively on standardized personnel operation and the good condition of the equipment, making it difficult to achieve inherent safety in the production process. Therefore, an anode guide rod anti-fall device is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an anode guide rod anti-fall device, including a bracket. The lower end of the bracket is connected to a clamp, and the upper end of the bracket is connected to a linkage rod. The linkage rod is hinged to a fixed frame via a hinge shaft. The fixed frame is a vertical frame, and the lower end of the vertical frame has a U-shaped groove with an opening facing downwards. The two ends of the hinge shaft are connected to the side walls on both sides of the U-shaped groove. The two ends of the linkage rod are away from the fixed frame. One end of the linkage rod is connected to a spring and a connecting rod. The upper end of the spring is connected to the upper end of the vertical frame, and one end of the connecting rod is connected to the lower end of the bracket.

[0004] Preferably, the clamp is a U-shaped anti-fall clamp, with the opening of the clamp facing away from the connecting rod.

[0005] Preferably, the spring is a tension spring.

[0006] Preferably, a baffle is fitted to the end of the linkage rod away from the spring.

[0007] This utility model also includes other components that enable the anode guide rod anti-fall device to function properly, such as a multi-functional unit clamp assembly that works in conjunction with the anode guide rod anti-fall device. Furthermore, devices or components not specified in this utility model, such as brackets, hydraulic cylinders, springs, and clamps in the multi-functional unit clamp assembly, all employ conventional techniques and equipment in the field.

[0008] Working principle: When in use, the upper end of the fixed frame is fixedly connected to the fixed end of the hydraulic rod of the multi-functional unit clamp assembly. The telescopic end of the hydraulic rod is connected to the clamp. The baffle is fixed on the telescopic end of the hydraulic rod above the clamp and corresponds to the linkage rod vertically. This ensures that when the hydraulic rod retracts, the baffle moves up and pushes the linkage rod to rotate around the hinge axis.

[0009] When the hydraulic rod retracts, the clamp holding the anode guide rod rises, and the linkage rod hits the baffle. As the hydraulic rod continues to retract, the linkage rod rotates around the hinge axis under the pressure of the baffle. The connecting rod connected to the linkage rod pushes the bracket. When the anode rises to the upper limit, the anti-fall clip connected to the lower end of the bracket is inserted horizontally into both sides of the clamp (pushing the anti-fall clip horizontally into the clamp's opening and closing path to physically prevent the clamp from opening accidentally), thus preventing the anode from falling due to incomplete clamp closure and improving safety. At this point, the anode can be safely transported. When the hydraulic rod extends, causing the anode to move away from the upper limit, the spring pulls the linkage rod, removing the anti-fall clip from the clamp and removing it from the clamp's working area without affecting the use of other mechanisms.

[0010] This application uses mechanical logic to seal equipment defects, achieving a forced "lock-in" state through a purely mechanical structure. The anti-fall card will only be fully released when the operator raises the anode to the upper limit position, without relying on the vigilance of personnel or the precision of operation, thus fundamentally preventing the occurrence of dangerous situations.

[0011] This utility model has the following beneficial effects:

[0012] 1. Through the forced locking function of the purely mechanical structure, the risk of anode falling is eliminated in all aspects, building a solid safety line for personnel and equipment and achieving inherent safety in production;

[0013] 2. Effectively overcomes traditional safety hazards such as equipment wear, spring failure, and human error.

[0014] 3. Zero operational burden, with safe actions seamlessly integrated into the normal lifting process of the equipment, requiring no additional personnel intervention; the automatic release design does not affect the operation of other mechanisms and ensures production efficiency.

[0015] 4. Reduced maintenance costs: Purely mechanical design with no electrical components, excellent dust resistance and high temperature resistance, high reliability; reduces impact damage to equipment caused by anode falling, lowers equipment maintenance frequency and costs, extends the overall service life of the equipment, and improves the economic benefits of enterprises.

[0022] Example

[0023] like Figure 1-3 As shown, this utility model provides an anode guide rod anti-fall device, including a bracket 5. The lower end of the bracket 5 is connected to a clamp 4, and the upper end of the bracket 5 is connected to a linkage rod 2. The linkage rod 2 is hinged to a fixed frame 1 via a hinge shaft. The fixed frame 1 is a vertical frame, and the lower end of the vertical frame is provided with a U-shaped groove with an opening facing downwards. The two ends of the hinge shaft are connected to the side walls on both sides of the U-shaped groove. The two ends of the linkage rod 2 are away from the fixed frame 1. One end of the linkage rod 2 is connected to a spring 3 and a connecting rod 7. The upper end of the spring 3 is connected to the upper end of the vertical frame, and one end of the connecting rod 7 is connected to the lower end of the bracket 5.

[0024] The clamp 4 is a U-shaped anti-fall clamp, and the opening of the clamp 4 faces away from the connecting rod 7.

[0025] The spring 3 is a tension spring 3.

[0026] The end of the linkage rod 2 away from the spring 3 is fitted with a baffle 6.

[0027] In use, the upper end of the fixed frame 1 is fixedly connected to the fixed end 10 of the hydraulic rod of the multi-functional unit clamp 12 assembly, the telescopic end 11 of the hydraulic rod is connected to the clamp 12, and the baffle 6 is fixed on the telescopic end 11 of the hydraulic rod above the clamp 12 and corresponds vertically with the linkage rod 2 to ensure that when the hydraulic rod retracts, the baffle 6 moves upward to push the linkage rod 2 to rotate around the hinge axis.

[0028] When the hydraulic rod retracts, the clamp 12 holds the anode guide rod 9 of the anode 8 and rises. The linkage rod 2 touches the baffle 6. As the hydraulic rod continues to retract, the linkage rod 2 rotates around the hinge axis under the pressure of the baffle 6. The connecting rod 7 connected to the linkage rod 2 pushes the bracket 5. When the anode 8 rises to the upper limit, the anti-fall clip connected to the lower end of the bracket 5 is inserted horizontally into both sides of the clamp 12 (pushing the anti-fall clip horizontally into the opening and closing path of the clamp 12 to physically prevent the clamp 12 from opening accidentally), thus preventing the anode 8 from falling due to the clamp 12 not closing properly and improving safety. At this time, the anode 8 can be safely transported. When the hydraulic rod extends and drives the anode 8 away from the upper limit, the spring 3 pulls the linkage rod 2 to pull the anti-fall clip away from the clamp 12 and remove it from the working area of ​​the clamp 12 without affecting the use of other mechanisms.

[0029] This embodiment features an intelligent interlocking mechanism: using the inherent hydraulic stroke of the equipment (the stroke of the hydraulic rod of the multi-functional unit clamp assembly) as the trigger signal to automate the protective action, completely eliminating the reliance on human attention and operational precision; rigid locking technology: the moment the equipment reaches the upper limit, it is forcibly locked into an irreversible state, preventing danger from occurring at the source; automatic reset function: after the equipment leaves the upper limit, the anti-fall clip automatically releases, requiring no additional manual operation and ensuring smooth production.

[0030] The hydraulic rods, clamps, springs, etc. involved in the anode guide rod anti-fall devices in the above-mentioned embodiments are all existing technologies. This application does not make any improvements to them, but only utilizes their existing functions. For their specific structure and principle, please refer to the product manual or existing technical data, which are all existing technologies.
