Description

Technical Field

[0001] The invention belongs to the field of electrolytic anode welding maintenance production, and in particular relates to an anode guide rod pressing device of an electrolytic rotary welding platform. Background Art

[0002] The anode of an aluminum electrolytic cell consists of three main components: an aluminum guide rod, a steel claw, and an anode carbon block. Domestically, the majority of electrolytic aluminum connections utilize an aluminum-steel explosive welding block as a transition between the steel claw and the aluminum guide rod. This involves explosive welding the aluminum and steel components together. The aluminum side of the explosive welding block is then welded to the aluminum guide rod to form an aluminum-to-aluminum weld, while the steel side of the explosive welding block is welded to the steel claw to form a steel-to-steel weld.

[0003] When the electrolytic anode guide rods used in large prebaked electrolytic cells are welded to the explosive weld blocks on the end faces of the steel claw body cross beams using a continuous rotary welding platform for the electrolytic anode guide rods, it is difficult to achieve tight compaction of the explosive weld blocks between the guide rod end faces and the steel claw body end faces solely by the weight of the anode guide rods themselves. This results in insufficient effective conductive area between the guide rods and the steel claw body after the anode guide rod group is welded together, and a large anode voltage drop after the anode is put into use in the electrolytic cell, which is very unfavorable for reducing the power consumption per ton of aluminum in electrolytic production. Summary of the Invention

[0004] In view of the above problems, the present invention provides the following technical solutions:

[0005] An anode guide rod clamping device for an electrolytic rotary welding platform, the welding platform comprising: a side bracket 9, the anode guide rod clamping device comprising: a jack 1, a clamping device base 5, a first clamping component, and a second clamping component, wherein the first clamping component and the second clamping component are relatively arranged on the clamping device base 5, one end of the jack 1 is connected to the clamping device base 5, and the other end is connected to the side bracket 9.

[0006] Furthermore, the first clamping component and the second clamping component both include a guide rod clamping piece 3 and an adjustment mechanism. The guide rod clamping piece 3 is provided at one end of the adjustment mechanism, and the adjustment mechanism is rotatably connected to the clamping device base 5 .

[0007] Furthermore, through holes are provided on both opposite sides of the clamping device base 5, and the adjustment mechanism includes a nut 4 and a bolt 15, wherein the nut 4 is concentrically arranged on the clamping device base 5 with the through hole, the bolt 15 is threadedly connected to the nut 4, and one end of the bolt 15 passes through the through hole and is connected to the anode guide rod clamping plate 3.

[0008] Furthermore, the jack 1 includes a first jack 11 and a second jack 12 , and the first jack 11 and the second jack 12 are relatively arranged on the pressing device base 5 .

[0009] Furthermore, the pressing device base 5 is U-shaped.

[0010] Furthermore, the anode guide rod clamping device is fixed to the welding platform through a first clamping component and a second clamping component.

[0011] Furthermore, the welding platform also includes an anode guide rod positioning fixture 13, an anode guide rod 17, and a connecting plate 14. The anode guide rod positioning fixture 13 is connected to the connecting plate 14, the connecting plate 14 is connected to the side bracket 9, and the anode guide rod 17 is fixed by the anode guide rod positioning fixture 13.

[0012] Furthermore, the welding platform also includes a welding surface 6, an explosive welding block 7 and a steel claw body 8, wherein the welding surface 6, the explosive welding block 7 and the steel claw body 8 are sequentially connected to the bottom of the anode guide rod 17.

[0014] Furthermore, a welding work platform ground base 16 is provided below the welding platform.

[0015] The anode guide rod clamping device of the present invention applies external pressure to significantly improve the performance of the pressure-bonding between the guide rod end face and the explosive weld block on the steel claw body end face. Simultaneously, the clamping surface between the clamping device and the anode guide rod is crimped by end face crimping, eliminating the problem of damage to the guide rod surface caused by the clamping parts during the clamping process. The guide rod is clamped by tightening and loosening the screw.

DETAILED DESCRIPTION

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] like Figure 1-3 As shown, the anode guide rod clamping device includes: a jack 1, a first clamping component, a second clamping component, and a clamping device base 5. The jack 1 includes a first jack 11 and a second jack 12. It should be noted that the first jack 11 and the second jack 12 are arranged opposite each other on the clamping device base 5. One end of the jack 1 is connected to the clamping device base 5, and the other end is connected to the side bracket 9.

[0026] The first clamping component and the second clamping component both include a guide rod clamping piece 3 and an adjustment mechanism. The guide rod clamping piece 3 is arranged at one end of the adjustment mechanism, and the adjustment mechanism is rotatably connected to the clamping device base 5.

[0027] The clamping device base 5 is provided with through-holes on opposite sides. The adjustment mechanism includes a nut 4 and a bolt 15. The nut 4 is arranged concentrically with the through-hole on the clamping device base 5. The bolt 15 is threadedly connected to the nut 4. One end of the bolt 15 passes through the through-hole and is connected to the guide rod clamping piece 3. The clamping device base 5 is U-shaped, which facilitates the use of the anode guide rod clamping piece 3 and the guide rod clamping nut 4 to fix it to the side bracket 9 of the welding platform, and also facilitates the disassembly of the anode guide rod clamping device.

[0028] It should be noted that the adjustment mechanism realizes the flexible movement of the clamping device through the cooperation of the bolt 15, the nut 4 and the anode guide rod clamping piece 3. The adjustment mechanism facilitates the disassembly of the clamping device, thereby improving the utilization rate of the clamping device.

[0029] It should be noted that the anode guide rod clamping device first applies a clamping force in the reverse direction by lifting the jack 1, so that the explosive welding block 7 and the anode guide rod 17 are tightly compacted, and then the anode guide rod clamping device is moved by adjusting the first clamping component and the second clamping component, and the clamping force is applied in the reverse direction by lifting the jack 1 again, so that the steel claw body 8 and the anode guide rod 17 are tightly compacted.

[0030] It should be noted that in the prior art, it is difficult for the anode guide rod 17 to achieve tight compaction between the end face and the explosive welding block 7 on the end face of the steel claw body 8 by its own weight alone. Therefore, in order to address the problem in the prior art that it is difficult for the end face to be tightly compacted between the explosive welding block 7 on the end face of the steel claw body 8, in this embodiment, a jack 1 is provided on the clamping device of the anode guide rod 17, and external pressure is applied to greatly improve the crimping performance of the end face of the anode guide rod 17 and the explosive welding block 7 on the end face of the steel claw body 8, thereby solving the problem in the prior art that it is difficult for the anode guide rod 17 to achieve tight compaction between the end face and the explosive welding block 7 on the end face of the steel claw body 8.

[0031] It should be noted that the material of the anode guide rod 17 itself is relatively soft, so during the clamping process, the clamping parts can easily cause damage to the surface of the anode guide rod 17. Therefore, the clamping surface between the clamping device and the anode guide rod 17 adopts end face crimping to solve the problem that the clamping parts can easily cause damage to the surface of the anode guide rod 17 during the clamping process.

[0032] It should be noted that a nut 4 is provided on the anode guide rod clamping device, which is designed as an integrated guide rod clamping body. The anode guide rod 17 is clamped by loosening or tightening the screw. After clamping the anode guide rod 17, the jack 1 is used to apply a clamping force in the reverse direction and apply external pressure to achieve the effect of crimping the end face of the guide rod with the end face of the steel claw body 8, thereby improving the work efficiency of installing, clamping and disassembling the anode guide rod clamping device and reducing the labor intensity of the operators.

[0033] like Figure 4As shown, the welding platform includes: a welding surface 6, an explosive welding block 7, a steel claw body 8, a side bracket 9, a welding work platform base 10, an anode guide rod 17, an anode guide rod positioning fixture 13 and a connecting plate 14. It should be noted that a ground base 11 is provided below the welding platform, the welding surface 6 is provided below the anode guide rod clamping device, the explosive welding block 7 is provided below the welding surface 6, the steel claw body 8 is provided below the explosive welding block 7, the welding work platform base 10 is provided below the steel claw body 8, the side bracket 9 is provided at the left end on the welding work platform base 10, the anode guide rod positioning fixture 13 includes a first anode guide rod positioning fixture and a second anode guide rod positioning fixture, the two anode guide rod positioning fixtures are connected by a connecting plate 14, the connecting plate 14 is connected to the side bracket 9, and the anode guide rod 17 is fixed by the anode guide rod positioning fixture 13.

[0034] like Figure 5 As shown, the anode guide rod clamping device is connected to the side bracket 9 and the anode guide rod 17 through the clamping device base 5. The anode guide rod clamping device is connected to the clamping surface of the anode guide rod 17 by end face crimping, which solves the problem of damage to the guide rod surface caused by the clamping parts during the clamping process in the prior art.

[0035] It's important to note that steel claws are crucial conductive components in the electrolytic aluminum industry. Available in three-, four-, six-, and eight-claw configurations, they form the anode guide rod assembly along with the aluminum guide rod and anode carbon block. The specialized use of steel claws places stringent requirements on the center-to-center distance between the claws. Six- and eight-claw configurations, however, present significant challenges in controlling this distance due to their large number and two-dimensional nature. Exceeding this standard often leads to increased handling costs and, in severe cases, scrapping, directly impacting the company's profitability.

[0036] It should be noted that the explosive welding block 7, also known as a reinforced explosive welding block, anode explosive welding block, or steel-aluminum explosive welding block, is a metal composite material produced using explosive welding. As a new welding process, explosive welding combines pressure welding, fusion welding, and diffusion welding. It can weld together various metals with significantly different strengths, different expansion coefficients, and incompatible properties. This saves precious metals and facilitates the rational combination and matching of the properties of the composite material and the base material. It is widely used in the electrolytic aluminum industry and the metallurgical industry.

[0037] It should be noted that in the prior art, the fixed clamping device has a small installation space and a complex structure. Therefore, the present invention adopts a separate clamping device to solve the difficulties of the overhead crane lifting the guide rod and aligning the explosive welding block 7 on the end face of the steel claw body 8 during the welding process of the anode guide rod group, and lifting it away from the welding platform after the welding is completed. The fixed clamping device has a small installation space and a complex structure.

[0038] It should be noted that the anode guide rod 17 is a new type that allows for easy replacement of steel columns. Furthermore, when the weld between the steel column and the steel claw base cracks, it can be repaired or re-welded. This saves material for the explosive welding block 7 and reduces the degree of heat applied to the explosive welding block 7 during the welding operation. Due to the long service life of the anode guide rods 17, as well as transportation and outdoor storage, all of the anode guide rods have varying degrees of bending and rust. Some of the anode guide rods also have defects such as cracked explosive welding blocks, cracked steel claws, rotten claws, and fallen claws. These anode guide rods cannot be used in electrolysis unless they are repaired.

[0039] It should be noted that a jack 1 refers to a lightweight lifting device that uses a rigid lifting member as a working mechanism to lift a heavy object within the limited stroke of a top support or bottom claw. Jacks 1 are classified into mechanical and hydraulic jacks, each operating on different principles. In principle, the most fundamental principle of hydraulic transmission is Pascal's law, which states that pressure is constant everywhere in a liquid. Therefore, in a balanced system, the smaller piston exerts less pressure, while the larger piston exerts greater pressure, maintaining the liquid's stability. Therefore, through the transfer of fluid, different pressures can be achieved at different ends, achieving a variable force. Common hydraulic jacks utilize this principle to transmit force. In a mechanical jack, by reciprocating the handle, the claws drive the ratchet wheel to rotate, and the small bevel gear drives the large bevel gear, rotating the lifting screw, thereby raising or lowering the lifting sleeve and achieving the lifting force.

[0040] Therefore, the present invention adopts a mechanical jack, which is also called a screw jack. It is driven by manpower through a screw pair, and a screw or nut sleeve serves as a lifting member. Ordinary screw jacks rely on the self-locking effect of the thread to support heavy objects. They have a simple structure, but low transmission efficiency and slow return. The thread of the self-lowering screw jack has no self-locking effect and is equipped with a brake. When the brake is released, the heavy object can be quickly lowered by itself, shortening the return time, but this jack has a more complex structure. The screw jack can support heavy objects for a long time, with a maximum lifting capacity of 100 tons, and is widely used. After the horizontal screw is installed on the lower part, the heavy object can also be moved laterally a small distance.

[0041] It should be noted that screw jacks can be made into multi-stage telescopic models to further reduce their overall height and increase their lifting distance. These lightweight lifting devices use a rigid lifting member as the working device, lifting heavy objects within their travel range via a top support or bottom claw. The head undergoes special heat treatment and features a plum blossom-shaped anti-slip surface, making it less susceptible to slippage, bending, or breaking during use. The entire machine features multiple anti-counterfeiting features, effectively guaranteeing quality and after-sales service. The oil filling port utilizes a spiral seal, offering excellent sealing performance, easy assembly and disassembly, and convenient use. The screw jack features an adjustable safety valve, and the chassis has been enlarged and thickened to accommodate a variety of harsh surfaces, ensuring safety. High-quality seals, high-quality materials, and specialized manufacturing processes enhance overall performance. Screw jacks are lightweight, easy to carry and maintain, safe and reliable to use, simple in construction, and offer a high lifting capacity, making them ideal large-tonnage mechanical jacks.

[0042] The present invention designs and manufactures an anode guide rod clamping device for a welding platform, which features easy installation and disassembly, and provides effective side clamping and vertical compression of the guide rod. This effectively addresses the technical challenges of insufficient conductive area between the welded end face of the guide rod and the explosive weld block 7 on the end face of the steel claw body 8, resulting in excessive anode voltage drop. By achieving side clamping and vertical compression of the guide rod, the resistance between the welded end face of the guide rod and the explosive weld block 7 on the end face of the steel claw body 8 is effectively reduced, thereby increasing the effective conductive area between the guide rod and the steel claw body 8 in the anode guide rod assembly. This has the positive effect of reducing power consumption per ton of aluminum in the electrolytic production process.
