Description

Technical Field

[0001] This application belongs to the field of mechanical equipment technology, specifically relating to a device for unloading anode broken guide rods. Background Technology

[0002] As a crucial foundation of the national economy, the continuity and stability of the aluminum electrolysis industry's production process directly determine product quality and production efficiency. During the operation of an aluminum electrolysis cell, the anode carbon block assembly is a core component, consisting of anode carbon blocks connected to aluminum guide rods via steel claws. It performs the dual functions of conducting high current and participating in the electrolysis reaction. Due to the harsh working environment of the electrolysis cell, the anode carbon block assembly needs to be replaced periodically. Under prolonged high-temperature cycling, the welded joint between the aluminum guide rod and the steel claw is prone to fracture and separation due to thermal stress fatigue, resulting in broken guide rods. If broken guide rods are not promptly removed from the production line, it can lead to insufficient anode supply, affecting the continuity of electrolysis cell production. Therefore, removing broken guide rods from the production line is a routine and critical procedure in the aluminum electrolysis workshop.

[0003] Traditionally, this task relies on manual labor combined with general equipment, primarily using a lifting platform and manual support.

[0004] First, the lifting platform operator needs to adjust the lifting points to keep the broken guide rod balanced. After lifting, the direction needs to be manually corrected before it is slowly transported to the designated area. Handling a single broken guide rod takes as long as 20-30 minutes, which is inefficient. Because electrolytic aluminum production requires extremely high continuity, when multiple broken guide rods accumulate, it is necessary to temporarily stop the machine for handling, which seriously affects the smooth progress of production.

[0005] Secondly, at least two workers are required to operate the hoist: one to lift the broken guide rod, and the other to support it to prevent it from tipping over. Because manual support makes it difficult to stabilize the center of gravity, the broken guide rod is highly susceptible to lateral tilting during lifting. Furthermore, manually supporting the broken guide rod requires bearing hundreds of kilograms of lateral force, which can easily lead to muscle strain over prolonged periods. The operation of the hoist and the manual support must be highly synchronized; any miscoordination can easily cause an accident. In addition, the hoist's lifting height is limited; if the broken guide rod tilts at too large an angle, it may collide with the upper structure, creating a secondary safety hazard.

[0006] Third, this work mode, which relies on human experience, not only increases the cost of job training, but also makes it difficult to guarantee the stability of work quality. Utility Model Content

[0007] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies, namely, the low efficiency, high safety risk and high labor cost of the broken guide rod unloading work.

[0008] In view of this, the present invention provides a device for unloading a broken anode conductor rod. Using this device, only one worker is needed to stably, safely and quickly unload the broken conductor rod and transport it to the designated location.

[0009] Specifically, the following technical solutions are included:

[0010] According to an embodiment of this application, a device for unloading a broken anode guide rod is provided, including a base plate, a receiving frame, and a forklift bracket; the receiving frame is disposed on the base plate for accommodating the broken guide rod; the forklift bracket is connected to opposite sides of the receiving frame.

[0011] Furthermore, the receiving frame includes a base frame, side posts, and reinforcing plates; the base frame is disposed on the base plate; the four side posts are all vertically disposed on the base plate and connected to the inner side surface of the base frame; a reinforcing plate is connected between every two adjacent side posts.

[0012] Furthermore, the reinforcing plate is provided in three sets, located at both ends and the middle of the side post respectively.

[0013] Furthermore, the base frame is square, and the four side posts are respectively connected to the inner sides of the four corners of the base frame.

[0014] Furthermore, the forklift bracket is horizontally mounted on the reinforcing plate located in the middle of the side post.

[0015] Preferably, the forklift bracket includes a seamless square tube; the length of the seamless square tube is greater than the side length of the receiving frame, and the forklift entry end of the seamless square tube protrudes from the receiving frame.

[0016] Furthermore, the side length of the base plate is at least 60% longer than the side length of the receiving frame.

[0019] Preferably, the housing frame and the base plate, the base frame and the side post, the side post and the reinforcing plate, and the forklift bracket and the reinforcing plate are all connected by welding.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0028] In view of this, an apparatus for unwinding a broken anode conductor is provided according to an embodiment of this application, such as... Figure 1 , Figure 2 As shown, it includes a base plate 1, a receiving frame 2, and a forklift bracket; the receiving frame 2 is disposed on the base plate 1 and is used to receive the broken guide rod; the forklift bracket is connected to the opposite sides of the receiving frame 2.

[0029] Furthermore, in one embodiment, the receiving frame 2 includes a bottom frame 21, side posts 22, and reinforcing plates 23; the bottom frame 21 is disposed on the bottom plate 1; the four side posts 22 are all vertically disposed on the bottom plate 1 and connected to the inner side surface of the bottom frame 21; a reinforcing plate 23 is connected between every two adjacent side posts 22.

[0030] Furthermore, in one embodiment, the reinforcing plate 23 is provided in three sets, located at both ends and the middle of the side post 22 respectively.

[0031] Specifically, the four side posts 22 form a receiving space 24 for accommodating the broken guide rod, allowing the broken guide rod to be placed longitudinally within the receiving space 24. The forklift bracket is used to support the two forks of the forklift, enabling the forklift to transport the entire device. The reinforcing plate 23, on the one hand, further enhances the connection rigidity between the base plate 1 and the receiving frame 2, preventing the side posts 22 from breaking or deforming; on the other hand, it allows the receiving frame 2 to support the broken guide rod in all directions in the horizontal plane.

[0032] Furthermore, in one embodiment, the base frame 21 is square, and the four side posts 22 are respectively connected to the inner sides of the four corners of the base frame 21.

[0033] In actual working conditions, the side length of the bottom frame 21 is 500mm to ensure compatibility with different types of broken guide rods. The diagonal deviation of the frame formed by the side posts 22 is controlled within ±2mm to ensure a square structure and prevent jamming when the broken guide rod is inserted.

[0034] Furthermore, in one embodiment, the forklift bracket is horizontally mounted on the reinforcing plate 23 located in the middle of the side post 22.

[0035] Specifically, the forklift bracket is mounted on the reinforcing plate 23, increasing the connection area between the forklift bracket and the housing frame 2, making the connection between the two more stable. In actual working conditions, for ease of forklift operation, the distance between the forklift bracket and the base plate 1 is 750mm.

[0036] Preferably, in a specific embodiment, the forklift bracket includes a seamless square tube 3; the length of the seamless square tube 3 is greater than the side length of the receiving frame 2, and the forklift inlet end 31 of the seamless square tube 3 protrudes from the receiving frame 2.

[0037] Specifically, the inner wall of the seamless square tube 3 is polished to allow for smooth insertion of the forklift's forks and prevent the device from falling off during transport. The two seamless square tubes 3 are arranged in a symmetrical, centered, and extended layout to precisely match the spacing of the standard forklift forks, ensuring balanced force on the device after forklift insertion. The forklift entry end 31 of the seamless square tube 3 protrudes from the receiving frame 2, forming a "lever balance" fulcrum to prevent the device from sliding on the forks during transport. This structure evenly transmits the lifting force of the forklift to the receiving frame 2 through the seamless square tube 3, achieving a "rigid connection" rather than "flexible suspension," completely eliminating the swaying problem during lifting and is the core guarantee for efficient transport of the device. In actual working conditions, the seamless square tube 3 has a length of 650mm, a cross-section of 180mm×180mm square, and a wall thickness of 8mm. This ensures that the forklift insertion depth meets the requirements for safe forklift transport while allowing the forklift entry end 31 of the seamless square tube 3 to extend sufficiently beyond the receiving frame 2 for forklift operation.

[0038] Furthermore, in one embodiment, the side length of the base plate 1 is at least 60% longer than the side length of the receiving frame 2.

[0039] Specifically, the base plate 1 increases the ground contact area, reducing the overall pressure of the device on the ground and preventing settlement on the workshop's concrete floor. Simultaneously, the side length of the base plate 1 is at least 60% longer than the side length of the receiving frame 2, forming a strong external support and further enhancing the overall anti-overturning stability of the device. In actual operation, the side length of the base plate 1 is 800mm, expanding the ground contact area to 0.64㎡ and reducing the ground pressure to below 0.02MPa.

[0040] Preferably, in a specific embodiment, the side post 22 is a triangular steel.

[0041] In actual operation, the side post 22 is a ∠75×8 triangular steel bar with a length of 1.5 meters. The triangular steel has a right-angled triangle cross-section, with its two legs capable of bearing longitudinal and lateral loads respectively. Its bending strength is 30% higher than that of square steel of the same weight, effectively resisting the impact force when the broken guide rod is inserted and the lateral force during transport. The device dimensions match the diameter of the broken guide rod, ensuring smooth insertion and establishing three-point positioning through the contact between the base plate 1 and the inner wall of the reinforcing plate 23 with the broken guide rod, limiting its radial sway. This design replaces the traditional single-point suspension method of the elevator, structurally solving the problem of the broken guide rod easily tipping over, and providing a fundamental guarantee for the device's safety performance. Furthermore, the side post 22 can be made from scrap triangular steel, further reducing production costs.

[0042] Preferably, in a specific embodiment, the base plate 1, the base frame 21, and the reinforcing plate 23 are all steel plates.

[0043] In actual operation, the base plate 1 is an 800mm×800mm, 10mm thick Q235 steel plate, making its weight account for 40% of the total weight of the device. This lowers the overall center of gravity of the device by 300mm, creating a stable, bottom-heavy structure that ensures the stability of the device under off-center loads, a necessary condition for safe transport. Actual tests show that even with a 100mm shift in the center of gravity of the broken guide rod, the device remains stable.

[0044] Preferably, in a specific embodiment, the housing frame 2 and the base plate 1, the base frame 21 and the side post 22, the side post 22 and the reinforcing plate 23, and the forklift bracket and the reinforcing plate 23 are all connected by welding.

[0045] In actual working conditions, each weld length is ≥100mm, weld leg height is ≥8mm, and a diagonal symmetrical welding process is used to reduce welding stress. After welding, stress relief treatment is required by hammering.
