Description

Technical Field

[0001] This utility model belongs to the field of aluminum electrolysis production, and specifically relates to a device for repairing aluminum electrolysis anode clamps. Background Technology

[0002] Currently, during the electrolytic aluminum production process, problems such as screw breakage, bolt stripping, and screw deformation occur in the anode clamps. The following methods are currently used to address these issues:

[0003] 1. Traditionally, repairs are performed by personnel on the ground using wrenches. This method is extremely difficult, labor-intensive, and inefficient. The most common repair method involves cleaning the anode clamp surface with a cleaning agent to remove oil and dirt, thus maintaining the clamp's cleanliness. Lubricant is then applied to the rotating parts of the anode clamp to reduce friction and wear.

[0004] 2. The vast majority of actual damaged clamps are caused by slippage of the threads in the upper and lower shafts or wear of the lead screw. Repairing them is very difficult, and a large number of them are scrapped. Only a very small number are disassembled using gas welding tools and the upper and lower shafts or lead screws are replaced. Utility Model Content

[0005] The purpose of this invention is to provide a repair device for aluminum electrolysis anode clamps to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A maintenance device for aluminum electrolysis anode clamps includes a platform with legs at the bottom. A clamp fixing and disassembly assembly mechanism is provided on the platform. The clamp fixing and disassembly assembly mechanism includes a support, with supporting screws symmetrically arranged on both sides of the support. The supporting screws are parallel to the central axis of the support, and nuts are screwed onto the supporting screws. A clamping groove is symmetrically arranged on the top surface of the support. A movable clamping plate is provided above the support, with through holes symmetrically arranged on the movable clamping plate. The supporting screws are respectively inserted into the through holes, and the movable clamping plate is parallel to the top surface of the support.

[0008] To further realize this utility model, channel steels are symmetrically arranged on both sides of the support, the bottom surface of the channel steels is fixedly connected to the side wall of the support, the channel plates of the channel steels extend toward the side away from the side wall of the support, and the support screw is arranged between the two channel plates.

[0009] To further realize this utility model, the long side of the slot is parallel to the short side of the support, and the width of the slot matches the width of the clamp arm.

[0010] To further realize this utility model, a limiting block is provided at the center of the top surface of the support.

[0011] To further realize this utility model, the platform is also provided with a clamp fixing mechanism, which includes a short fixing rod and symmetrically arranged fixing slots. The center line between the two fixing slots is parallel to the short side of the platform. The short fixing rod is set close to the long side of the platform. The center of the short fixing rod and the ends of the two fixing slots form an isosceles triangle. The fixing slots are "「" structures. The horizontal plates at the top of the two fixing slots are set facing each other. The distance between the vertical plates of the two fixing slots is 420mm. The short fixing rod is a hollow steel column with a diameter of 85mm. A square fixing wrench is set inside the hollow steel column.

[0012] To further realize this utility model, the platform is also provided with a long fixing rod, which is a solid steel column with a diameter of φ45mm×360mm.

[0013] To further realize this utility model, the support, supporting screw, long fixing rod and short fixing rod are all perpendicular to the platform.

[0014] To further realize this utility model, a pull ring is provided at the center of the top surface of the movable clamp.

[0015] To further realize this utility model, the height of the support is 690mm, the length of the support screw is Φ35mm×250mm, and the sum of the width of the support and the thickness of the bottom surface of the channel steel is 450mm.

[0016] The advantages of this utility model compared to the prior art are as follows:

[0017] In this utility model, the support of the clamp fixing and disassembly assembly mechanism cooperates with the movable clamping plate to clamp the clamp. By adjusting the position of the nut on the support screw, the movable clamping plate is pressed tightly against the top surface of the clamp for fixing and limiting. The square fixing wrench set in the short fixing rod of the clamp fixing mechanism is used to fix and remove the central nut of the clamp. The two fixing grooves are used to fix the clamp arm of the clamp for maintenance and lubrication. The long fixing rod is used to facilitate the disassembly of the clamp when the clamp screw is stripped.

[0018] From a safety perspective, the entire clamping device is designed with precise dimensions, and the spacing and angles between each component have been rigorously calculated and tested to ensure that there will be no loosening or slippage during operation. Key components are all made of high-strength steel, possessing high impact resistance and wear resistance, effectively ensuring the safety of operators.

[0019] In terms of efficiency, this utility model adopts a highly integrated design, making the entire operation process simpler and faster.

[0020] This invention improves maintenance efficiency: the design of the clamp maintenance device makes it easier and less strenuous for operators to carry out maintenance work, effectively improving maintenance efficiency.

[0021] This invention reduces labor intensity: the clamp repair device reduces labor intensity through mechanized operation, making repair work easier.

[0022] This invention improves maintenance accuracy: the device's specialized design ensures accuracy during the maintenance process and effectively avoids maintenance quality problems caused by human error.

[0023] This invention saves on maintenance costs: using a clamp-type maintenance device can reduce the manpower and time costs required for maintenance, thereby reducing maintenance costs.

[0024] This invention extends the lifespan of electrolytic cell anode clamps: proper use of the clamp maintenance device can effectively reduce wear on electrolytic cell anode clamps and extend their service life.
