Description

Technical Field

[0001] This utility model relates to aluminum electrolysis equipment, specifically to a hoisting fixture for an electrolysis cell distributor. Background Technology

[0002] During the roasting and start-up process of the electrolytic cell, a large current flows through the cell. To prevent the large current from impacting the cell body, the current must be evenly distributed to each anode position. During the roasting and start-up period, shunts need to be installed on the horizontal busbar and the vertical busbar to reduce the impact of the large current on the cell body and ensure uniform current distribution at each anode position. One end of the shunt consists of a square iron sheet with two five-meter-long iron strips welded to its end face. The other end of the two iron strips is welded with a rhomboid iron strip.

[0003] The installation of the shunt was completed by six electrolysis workers. One worker lifted the square iron plate end of the shunt, one lifted the middle part, and two others lifted one end of the rhomboid iron plate. It was lifted from the electrolysis cell to the installation position. Then, two workers carried the square end of the shunt up the electrolysis cell to the horizontal busbar, where two installers used clamps to install one end of the shunt onto the busbar. The rhomboid ends of the shunt were clamped onto both sides of the busbar. Including the installers, the entire process required six people working together. The shunt itself was heavy, and under the influence of the strong magnetic field in the electrolysis plant, the shunt was prone to tilting and shifting during transport. The installation process was physically demanding for the electrolysis workers and could easily cause mechanical injuries. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting fixture for an electrolytic cell splitter.

[0005] To achieve the above objectives, the electrolytic cell diverter hoisting fixture provided by this utility model includes: two hoisting beams hinged at one end, forming a "V" shape; the ends of the hoisting beams are provided with lifting lugs, and the hoisting beams on the back of the lifting lugs are provided with lifting rings; and an opening and closing angle limiting device is provided between the hoisting beams.

[0006] This structure makes the diverter hoisting more stable, reducing the swaying caused by center of gravity shift in traditional hoisting methods; it prevents the hoisting beam from accidentally unfolding during hoisting, ensuring the structural integrity of the entire hoisting fixture and improving hoisting safety; it is suitable for diverters of different specifications, and the hoisting angle can be adjusted through the limit device, enhancing the versatility of the hoisting fixture.

[0007] Furthermore, the opening angle limiting device is a flexible chain, ensuring that the included angle between the two lifting beams does not exceed 25°. Due to the varying sizes and weights of the diverters, the included angle of the lifting beams needs to be within a safe range. The flexible chain's limiting mechanism avoids impacts from rigid structures while allowing for a certain angle adjustment range, providing better adaptability. The flexible chain absorbs impacts, reducing swaying caused by gravity or inertia during lifting and improving the stability of the lifting process. Limiting the maximum included angle to ≤25° ensures stable lifting of the diverter under different weights and sizes. It also prevents stress concentration caused by excessive opening, extends the service life of the lifting fixtures, and improves structural strength, stability, and safety.

[0008] Furthermore, the lifting beam is provided with a T-shaped lifting ring pointing downwards, and a flexible chain is provided between the T-shaped lifting ring and the lifting beam; the T-shaped lifting ring has a stronger force balancing ability than ordinary lifting rings, and can support the diverter more stably; the addition of a flexible chain between the lifting ring and the lifting beam allows the lifting ring to be adjusted within a certain range, avoiding excessive force concentration; this design can keep the diverter balanced during the lifting process, and will not tilt or rotate due to single-point force.

[0009] Reduces swaying during diverter hoisting, improves hoisting stability, and reduces the risk of accidents caused by unstable hoisting; buffers vibrations during hoisting, avoids impacts from direct rigid connections, and protects the diverter and hoisting equipment; applicable to diverters of different sizes, enhancing the adaptability of hoisting fixtures.

[0010] Furthermore, a flexible chain is installed between the lifting ring and the lifting beam; the lifting ring directly contacts the distributor and bears part of its weight; since the center of gravity of the distributor may shift, the addition of the flexible chain can achieve automatic center of gravity adjustment; this design allows the lifting beam to generate a certain buffering effect during lifting, reducing stress concentration. It buffers the impact force during lifting, reduces distributor swaying due to inertia, improves construction safety, enhances the distributor's self-adaptive ability during lifting, prevents additional stress from rigid connections, and reduces the risk of fatigue damage to the lifting beam and lifting ring.

[0011] Furthermore, the lifting beam is made of square tubing of stainless steel. Stainless steel (such as stainless steel) has high strength, high corrosion resistance, and high temperature resistance, making it very suitable for electrolytic cell environments and extending the service life of lifting equipment. Traditional carbon steel or aluminum alloys may be damaged by acid and alkali corrosion in electrolytic environments, while stainless steel can effectively prevent corrosion. The square tubing structure is more rigid than round tubing, which can reduce deformation during lifting, improve safety, reduce maintenance costs, and the long service life of stainless steel reduces the frequency of later maintenance and improves economic efficiency.

[0013] Figure 2 This is a top view of an embodiment of the present invention. Detailed Implementation

[0014] The following detailed description illustrates the specific implementation methods:

[0015] Example 1: As Figure 1 and Figure 2 As shown, the electrolytic cell distributor hoisting fixture mainly consists of two hoisting beams 1, lifting lugs 2, lifting rings 3, an opening / closing angle limiting device 6, and a flexible chain 5. Specifically: the hoisting beams 1 are made of high-strength square tubing with one end hinged to form an adjustable "V" shape to accommodate different specifications of electrolytic cell distributors; lifting lugs 2 are installed on the hoisting beams for connection to slings and hooks to bear the load required during hoisting; lifting rings 3 are installed on the hoisting beams 1 behind the lifting lugs 2, connected to the hoisting beams 1 by a flexible chain 5, for assisting in hoisting the distributor or other hoisting components; limiting devices 6 are installed between the hoisting beams 1 to control the opening / closing angle, preventing excessive expansion or closure of the hoisting beams to ensure stability during hoisting; the limiting device 6 is a flexible chain or guide bar to control the maximum opening / closing angle of the hoisting beams to not exceed 25°.

[0016] The hinged structure allows the lifting beam to automatically unfold to the appropriate angle according to the lifting requirements, improving adaptability; the dual lifting point design of the lifting lug 2 and lifting ring 3 makes the lifting process more stable and reduces lifting sway; the angle limiting device 6 ensures that the lifting beam will not exceed the safe range, preventing the diverter from tilting or becoming unstable during the lifting process, thus improving safety.

[0017] Example 2: To further enhance the safety of the diverter hoisting, a T-shaped lifting ring 4 is provided downwards on the hoisting beam 1. The T-shaped lifting ring 4 is connected to the hoisting beam 1 by a flexible chain. The function of the T-shaped lifting ring 4 is to provide a more stable lifting point for the diverter and ensure that the diverter will not overturn or tilt during the hoisting process. The flexible chain reduces the force impact caused by the rigid connection and prevents the diverter from shaking violently during the hoisting process. The position of the T-shaped lifting ring 4 can be adjusted according to different diverter shapes through the flexible chain, improving the versatility of the hoisting tooling.

[0018] Example 3: To improve the durability of the hoisting fixture, this example uses a square tube made of stainless steel as the hoisting beam 1. Stainless steel (such as 304 / 316 stainless steel) has good corrosion resistance and is particularly suitable for the acid and alkali environment of the electrolytic cell. The square tube structure is more impact-resistant than the round tube and can withstand greater hoisting stress. The wall thickness of the square tube can be designed according to the usage requirements. Usually, a stainless steel square tube with a wall thickness of 5mm to 10mm is selected to ensure high strength load-bearing capacity during the hoisting process.

[0019] Usage process:

[0020] When the shunt is hoisted, the nylon slings are attached to the three lifting lugs 2 at the beginning and end of the stainless steel hoisting beam 1, and the other end is suspended from the hook of the multi-functional gantry crane. The nylon slings are made of insulating material, which can effectively prevent the shunt from bridging with the busbar of the electrolytic cell, causing the DC current in the electrolytic cell to surge and burn out the electrical components of the multi-functional gantry crane.

[0021] The hanger is hoisted above the distributor, and the distributor is unfolded into a V-shape. The hanger is also unfolded into a V-shape, matching the size and shape of the distributor. The three lifting rings 3 and two T-shaped lifting rings 4 of the hanger are attached to the beginning, end, and middle of the distributor, respectively. The distributor is then lifted.

[0022] During hoisting, only three people are needed to support the distributor at its head and tail. As the hook moves, the distributor is hoisted to the designated position. Then, simply adjust the distributor's position from north-south to east-west. The nylon slings can be adjusted to raise the head and lower the tail of the distributor, fixing one end to the horizontal busbar of the electrolytic cell and the other end to the vertical busbar of the electrolytic cell. This process eliminates the need for manual lifting of the distributor, significantly reducing the labor intensity of the workers and improving operational safety.

[0023] This diverter lifting device is made entirely of recycled workshop materials, requiring no additional expenses. It is better suited to the high temperatures and strong magnetic fields of the factory environment, and is lightweight, flexible, and easy to carry. Its design and usage are better adapted to the on-site working environment.

[0024] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness or practicality of this utility model. The specific embodiments described in the specification can be used to interpret the claims.
