Description

Technical Field

[0001] This utility model relates to the field of outrigger structure technology, specifically to an inflatable outrigger device for an electrolytic aluminum lifting frame. Background Technology

[0002] During electrolysis, as the anode is continuously consumed, the busbar's position also descends. Since the busbar's descent stroke is limited, once it reaches its lowest position, it needs to be lifted back to its highest position using a busbar lifting frame before the anode continues to descend. During frame lifting, the small box clamps originally used to fix the busbar and anode guide rod are removed. The clamping cylinder of the busbar lifting frame provides clamping force to press the anode guide rod and busbar together, ensuring good contact between them and achieving good electrical conductivity.

[0003] After the busbar is lifted, the current distribution of each anode guide rod needs to be monitored manually to obtain the current distribution of the electrolytic cell. Any outriggers that are too tight or too loose need to be adjusted to ensure a uniform current distribution throughout the electrolytic cell and reduce the accelerated anode loss caused by uneven current distribution. Currently, most outriggers are adjusted using hydraulic pressure, but this method involves many components and is slow, which has certain shortcomings. Therefore, this technical solution is proposed for improvement. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing lifting frame support legs, which are slow to operate during adjustment and have a large weight, and to provide an inflatable support leg device for electrolytic aluminum lifting frames.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an inflatable support leg device for an electrolytic aluminum lifting frame, comprising a support leg body, a support cylinder provided on the side of the support leg body, a support rod provided at the bottom of the support cylinder, and an anti-reverse device provided on the side wall of the support rod, the anti-reverse device comprising a stop block telescopically disposed on the support rod.

[0006] Furthermore, a protective plate is provided on the outside of the support rod, and the protective plate is fixedly connected to the support leg body.

[0007] Furthermore, the support rod has a receiving groove on its side wall, the stop block has a rotating groove at its lower part, the rotating groove has a rotating shaft inside, and the rotating groove is a vertically arranged strip groove.

[0008] Furthermore, an elastic sheet is provided on the side wall of the receiving groove, and a protrusion that abuts against the elastic sheet is provided on the side of the stop block.

[0009] Furthermore, the upper part of the stop block is provided as an inclined surface, and the lower part of the stop block is provided as an arc-shaped surface.

[0010] The beneficial effects of this utility model embodiment are as follows: When it is necessary to lift the outrigger, gas at a certain pressure is injected into the support cylinder. The pressure of the gas pushes the piston of the cylinder to move, thereby driving the support rod to move downward, thus lifting the outrigger. Conversely, when it is necessary to lower the height of the outrigger, some of the gas in the support cylinder is released, reducing the pressure in the cylinder. The support rod moves downward under its own weight, completing the lowering operation of the outrigger. Compared with the traditional hydraulic method, this greatly reduces the number of related parts, simplifies the device structure, and increases the lifting speed, improving work efficiency. Furthermore, the response time of each outrigger can be controlled by a solenoid valve, allowing simultaneous control of multiple outrigger movements, greatly improving efficiency. The stop design significantly increases safety during use, reducing accidents and solving the shortcomings of traditional hydraulic outrigger adjustment methods, thus improving safety during use.

[0015] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] See Figures 1 to 3 This utility model discloses an inflatable outrigger device for an electrolytic aluminum lifting frame, mainly comprising an outrigger body 1. A support cylinder 2 is cleverly arranged on the side of the outrigger body 1, serving as the power source for the entire device and providing power support for the lifting and lowering of the outrigger. Each outrigger is equipped with one support cylinder 2, and a support rod 3 is connected to the bottom of the support cylinder 2. The support rod 3 is a key component for realizing the lifting and lowering of the outrigger and providing stable support. Simultaneously, an anti-reverse device is provided on the side wall of the support rod 3. This anti-reverse device effectively prevents the support rod 3 from retracting when subjected to force or used beyond its range during operation, ensuring the stability of the outrigger.

[0017] The support cylinder 2 is fixed to the side of the outrigger body 1 via a connecting structure. A support rod 3 is installed at the bottom of the support cylinder 2. When the outrigger needs to be raised, gas at a certain pressure is injected into the support cylinder 2. The gas pressure pushes the piston of the cylinder, which in turn moves the support rod 3 downward, thus raising the outrigger. Conversely, when the outrigger needs to be lowered, some of the gas in the support cylinder 2 is released, reducing the pressure inside the cylinder. The support rod 3 moves downward under its own weight, completing the lowering operation of the outrigger. This method of raising and lowering the outrigger using gas pressure, compared to the traditional hydraulic method, greatly reduces the number of related parts, simplifies the device structure, and also allows for faster lifting and lowering, improving work efficiency. Furthermore, the response time of each outrigger can be controlled by a solenoid valve, allowing for simultaneous control of multiple outrigger movements, greatly improving efficiency.

[0018] The anti-reverse device has a stop block 302 that is telescopically mounted on the support rod 3. Specifically, a receiving groove 301 is provided on the side wall of the support rod 3, and the stop block 302 is telescopically installed in the receiving groove 301. The lower part of the stop block 302 is provided with a rotating groove 303, which is a vertically arranged strip groove. A rotating shaft is provided inside the rotating groove 303, and the stop block 302 is rotatably connected to the support rod 3 through the rotating shaft, so that the upper part of the stop block 302 can rotate and telescopically move within a certain range. In use, the stop block 302 is generally inside the movable cylinder. When the support rod 3 moves downward, the stop block 302 will pop out. Since the structural strength of the support changes when the support rod 3 moves, in order to prevent sudden retraction and stop the support rod 3 from continuing to move backward, the stop block 302 plays a role in preventing reversal and ensuring safe use. To further enhance the reliability of the anti-reverse device, an elastic plate 4 is provided on the side wall of the receiving groove 301, and a protrusion abutting against the elastic plate is provided on the side of the stop block 302. When the stop block 302 is in the receiving groove 301, the stop block 302 remains stable, and the elastic plate is compressed, exerting an outward force. When the support rod 3 moves beyond the position of the stop block 302, the upper part of the stop block 302 extends under the action of force, increasing safety during use. The upper part of the stop block 302 is designed as a slope, which provides a stable support surface after the stop block 302 pops out and reduces the corresponding resistance. The design of the rotating groove 303 allows the stop block 302 to move upward when popped out, reducing the obstruction at the bottom. The lower part of the stop block 302 is provided with an arc-shaped surface, which improves the stability and reliability of the anti-reverse device and reduces damage caused by local stress concentration.

[0019] A protective plate is installed on the outside of the support rod 3, and the protective plate is fixedly connected to the support leg body 1. The main function of the protective plate is to protect the support rod 3 and the anti-retraction device, preventing corrosion and damage to the support rod 3 and the anti-retraction device caused by impurities such as molten aluminum and alumina dust during the electrolytic aluminum production process, thus extending the service life of the device. At the same time, the protective plate also plays a certain role in isolation, reducing interference from external factors to the support rod 3 and the anti-retraction device, and ensuring the normal operation of the device.

[0020] After the busbar is raised, the current distribution of each anode guide rod needs to be monitored individually. If an abnormal current distribution is found in a certain anode guide rod, it may be due to improper clamping of the outriggers. In this case, the operator can adjust the height of the outriggers by controlling the inflation and deflation of the support cylinder 2. If the outriggers are clamped too tightly, release some of the gas in the support cylinder 2 to lower the support rod 3 and reduce the clamping force of the outriggers on the anode guide rods; if the outriggers are clamped too loosely, fill the support cylinder 2 with gas to raise the support rod 3 and increase the clamping force of the outriggers on the anode guide rods. By continuously adjusting the height of each outrigger, the current distribution of the entire electrolytic cell is made uniform, thereby reducing the problem of accelerated anode loss caused by uneven current distribution, improving the efficiency and quality of electrolytic aluminum production. The design of the stop block 302 greatly increases the safety during use, reduces the occurrence of accidents, solves the shortcomings of traditional hydraulic outrigger adjustment methods, and improves the safety during use.
