Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic cells, and in particular to a welding and repair device for the anode busbar of an aluminum electrolytic cell. Background Technology

[0002] During daily use, the horizontal busbar and aluminum conductor rod of an aluminum electrolytic cell rub against each other, frequently causing arcing and discharge on the contact conductive surface. This results in arc craters and scratches, measuring 550mm in length and 140mm in width, which increases voltage drop and causes significant economic losses. To reduce this contact voltage drop and repair the scratched busbar, welding is required to fill the arc craters, followed by milling to smooth the busbar. Currently, the main online in-situ repair technologies for horizontal busbars under strong magnetic fields include thermal spraying, fusion welding, and self-fusion welding.

[0003] The side of the horizontal busbar that contacts the aluminum guide rod is also equipped with multiple support arms, as shown in the attached diagram. Figure 1 As shown, the support arm is used to support the horizontal busbar. However, during the welding process of the busbar using a robotic arm, the support arm will hinder the movement of the robotic arm as it moves horizontally.

[0004] Existing repair welding equipment cannot be directly mounted on the horizontal busbars of the electrolytic cell for repair welding. To repair the surface of the busbars, a robotic arm is usually used to drive the welding gun. However, robotic arms have strict requirements for the working space. In the narrow environment around the aluminum electrolytic cell, due to the compact equipment layout and small spacing between busbars, the robotic arm often cannot operate effectively, resulting in the inability to repair the busbars effectively. Utility Model Content

[0005] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0006] A welding device for repairing anode busbars in an aluminum electrolysis cell includes: a movable frame installed on one side of a horizontal busbar, the movable frame being configured to move along the length of the horizontal busbar; a drive plate installed on the movable frame on the other side of the horizontal busbar, the drive plate being configured to move along the vertical direction of the movable frame; and a welding torch installed on the drive plate for repairing and welding the anode busbars.

[0007] Preferably, the movable frame includes: an upper clamping arm mounted on the movable frame, the upper clamping arm being disposed at the top of the horizontal busbar; and a lower clamping arm mounted on the movable frame, the lower clamping arm being located below the upper clamping arm and disposed at the bottom of the horizontal busbar.

[0023] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0024] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0025] Reference Figures 2-6 A welding device for repairing anode busbars in an aluminum electrolysis cell includes: a movable frame 200 installed on one side of a horizontal busbar 100, the movable frame 200 being configured to move along the length of the horizontal busbar 100; a drive plate 300 installed on the movable frame 200, located on the other side of the horizontal busbar 100, the drive plate 300 being configured to move along the vertical direction of the movable frame 200; and a welding torch 400 installed on the drive plate 300 for repairing and welding the anode busbars.

[0026] In this embodiment, the movable frame 200 is installed on the horizontal busbar 100. The movable frame 200 can drive the drive plate 300 and the horizontal busbar 100 of the welding gun eye to move horizontally, which can adapt to the narrow environment around the electrolytic cell. Through the cooperation of the movable frame 200 and the drive plate 300, repair welding of different positions of the anode busbar can be realized. Moreover, the drive plate 300 can move flexibly in the vertical direction. When passing the support arm next to the horizontal busbar 100, the drive plate 300 can move downward and pass over the support arm. The movement of the movable frame 200 is not obstructed or affected.

[0027] The movable frame 200 includes: an upper clamping arm 201, which is mounted on the movable frame 200 and is located at the top of the horizontal busbar 100, and the number of upper clamping arms 201 is at least two; and a lower clamping arm 202, which is mounted on the movable frame 200 and is located below the upper clamping arm 201 and is located at the bottom of the horizontal busbar 100.

[0028] The main function of the upper clamping arm 201 is to clamp and position the horizontal busbar 100 from above, and at the same time provide an installation base for components such as the traveling wheel 206 and the power source 205. The lower clamping arm 202 works in conjunction with the upper clamping arm 201 to clamp and fix the horizontal busbar 100, ensuring the stability of the equipment during movement and welding.

[0029] The upper clamping arm 201 includes: a traveling wheel 206, installed at the bottom of the upper clamping arm 201, the traveling wheel 206 contacting the top of the horizontal busbar 100; a power source 205, installed at one end of the upper clamping arm 201, the power shaft of the power source 205 being connected to the traveling wheel 206; and a limiting plate 207, installed at the bottom of the upper clamping arm 201, the limiting plate 207 contacting one side of the horizontal busbar 100.

[0030] Driven by the power source 205, the traveling wheels 206 can roll on top of the horizontal generatrix 100, thereby driving the moving frame 200 to move along the length of the horizontal generatrix 100. The traveling wheels 206 are made of wear-resistant and high-strength materials to ensure that they can withstand the weight and friction of the equipment during long-term use, while ensuring smooth rolling. The power source 205 uses a servo motor, but a stepper motor can also be used. The function of the limit plate 207 is to laterally limit the movement of the moving frame 200, prevent the moving frame 200 from deviating during movement, and ensure that the moving frame 200 can move stably along the length of the horizontal generatrix 100.

[0031] The movable frame 200 further includes: an adjusting plate 500, mounted on the movable frame 200, with one end of the lower clamping arm 202 mounted on the adjusting plate 500; a lead screw 501, mounted on the movable frame 200, and threadedly connected to the adjusting plate 500; a knob 502, mounted on the top end of the lead screw 501; a through hole 203, formed on one side of the movable frame 200, with a movable seat 301 mounted on one side of the drive plate 300, and the movable seat 301 installed inside the through hole 203; and a slide rail 204, mounted on the inner wall of the through hole 203, with the movable seat 301 connected to the slide rail 204.

[0032] The function of the aforementioned adjusting plate 500 is to adjust the position of the lower clamping arm 202 to accommodate horizontal busbars 100 of different thicknesses. By adjusting the position of the lower clamping arm 202, the upper clamping arm 201 and the lower clamping arm 202 can form a tighter clamping force on the horizontal busbar 100, improving the stability of the equipment. The rotation of the lead screw 501 can drive the adjusting plate 500 to move up and down, thereby adjusting the position of the lower clamping arm 202; the lead screw 501 can be driven to rotate by rotating the knob 502. The knob 502 is designed to facilitate manual adjustment of the lead screw 501 by the operator, thereby adjusting the position of the lower clamping arm 202; the through hole 203 provides space for the movement of the drive plate 300, allowing the drive plate 300 to move vertically on the moving frame 200; the slide rail 204 guides the moving seat 301, ensuring smooth and stable vertical movement of the drive plate 300. The slide rail 204 adopts a high-precision guide rail design, which can reduce frictional resistance and improve the movement accuracy of the drive board 300. The slide rail 204 is an electric slide rail.

[0033] During use, the movable frame 200 is installed on one side of the horizontal busbar 100, with the upper clamping arm 201 positioned at the top of the horizontal busbar 100 and the lower clamping arm 202 positioned at the bottom of the horizontal busbar 100. The operator rotates the knob 502, which drives the lead screw 501 to rotate. The rotation of the lead screw 501 causes the adjusting plate 500, which is threaded to it, to move up and down, thereby adjusting the position of the lower clamping arm 202. This ensures that the upper clamping arm 201 and the lower clamping arm 202 tightly clamp the horizontal busbar 100 to accommodate different thicknesses. The horizontal busbar 100 ensures the stability of the equipment during movement and welding. The power source 205 is turned on, and the power shaft of the power source 205 drives the traveling wheel 206 to rotate. Under the drive of the power source 205, the traveling wheel 206 rolls on the top of the horizontal busbar 100, thereby driving the moving frame 200 to move along the length of the horizontal busbar 100, so that the moving frame 200 moves stably horizontally along the horizontal busbar 100. At the same time, it drives the drive plate 300 and the welding torch 400 installed on the moving frame 200 to move together.

[0034] When the moving frame 200 moves the equipment to the support arm position next to the horizontal busbar 100, the slide rail 204 installed on the inner wall of the through hole 203 drives the moving seat 301 installed on one side of the drive plate 300 and located in the through hole 203, so that the drive plate 300 moves downward in the vertical direction of the moving frame 200. After the drive plate 300 moves downward past the support arm, it is then moved to a suitable height position by the electric slide table as needed to continue the subsequent movement and welding operations. This ensures that the movement of the moving frame 200 is not blocked or affected by the support arm. Through the horizontal movement of the moving frame 200 and the vertical movement of the drive plate 300, the welding torch 400 installed on the drive plate 300 is moved to the position of the anode busbar that needs to be repaired and welded. The welding torch 400 is started to repair and weld the defective parts of the anode busbar. During the welding process, the horizontal movement speed of the moving frame 200 and the vertical position of the drive plate 300 can be adjusted according to the actual situation to complete the repair welding of different positions of the anode busbar.

[0035] In summary, compared with existing technologies, it has the following beneficial effects:

[0036] By installing the mobile frame 200 on one side of the horizontal busbar 100, the equipment can move horizontally along the busbar, and the drive plate 300 can move vertically on the mobile frame 200, enabling the equipment to flexibly move between the compactly arranged electrolytic cells, adapt to narrow spaces, and expand the operating range.

[0037] The movable frame 200 moves along the length of the busbar, and the drive plate 300 can be flexibly adjusted vertically, allowing the welding torch 400 to reach different positions on the busbar. When it encounters obstacles such as support arms next to the busbar, the drive plate 300 can move downwards to pass over them, and then reset to continue working, enabling the equipment to perform comprehensive repairs on busbars with complex layouts.
