Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum, and more specifically, to a device for preventing a lifting machine from being damaged. Background Art

[0002] In the production process of electrolytic aluminum, the anode hoist, as the core equipment of the electrolytic cell, plays a pivotal role. In daily operations, such as aluminum tapping, voltage adjustment, and tank position adjustment, all rely on the precise rotation of the hoist, which not only ensures the stable adjustment of the electrolytic cell voltage, but also helps to maintain the stability of the entire electrolytic cell operation curve. However, in actual production, due to the control of technical conditions and interference from other factors, the anode sometimes stretches its legs and grows its angles. If not discovered and handled in time, this abnormal condition is very likely to cause damage to the upper cover or shell of the hoist, which not only poses a huge safety hazard, but also carries many risks in replacement operations. What's worse, once the hoist is damaged, the electrolytic cell will not be able to adjust the voltage in time, resulting in production interruption, which seriously affects production efficiency and product quality. Utility Model Content

[0010] As a preferred technical solution of the utility model, the long bolts and nuts are arranged in groups of two, and there are a total of six groups movably installed inside the elevator body and the elevator upper cover.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 6 As shown, the utility model provides an anti-top-damage device for an elevator, including an elevator body 1, a long bolt 3 is movably installed inside the elevator body 1, a nut 4 is movably installed on the outer surface of the long bolt 3, a elevator cover 2 is movably installed on the top outer surface of the elevator body 1, a bolt gasket 7 is fixedly installed on the top of the elevator cover 2, and a spring 6 is fixedly installed between the two bolt gaskets 7.

[0022] The staff needs to fix the hoist cover 2 on the surface of the hoist body 1, and then slowly install the nut 4 into the long bolt 3, and then install the bolt gasket 7 on the top of the nut 4. Now, slowly install the spring 6 into the two bolt gaskets 7, and then slowly screw the long bolt 3 into the interior of the hoist body 1. Through the cooperation between the nut 4, spring 6 and bolt gasket 7, the hoist cover 2 is fixedly installed on the outer surface of the hoist body 1. The hoist cover 2 is fixed. During the operation of the hoist body 1, the hoist cover 2 will damage the hoist body 1 as the hoist body 1 runs. The cooperation between the nut 4, spring 6 and bolt gasket 7 prevents the hoist cover 2 from falling off, thereby completing the protection of the hoist cover 2.

[0023] It is necessary to fix the upper cover 2 of the hoist on the outer surface of the hoist body 1, and then slowly install the nut 4 into the long bolt 3, and then install the bolt gasket 7 on the top of the nut 4. Now, slowly install the spring 6 into the two bolt gaskets 7, and then slowly screw the long bolt 3 into the interior of the hoist body 1. Through the cooperation between the nut 4, spring 6 and bolt gasket 7, the upper cover 2 of the hoist is fixed on the outer surface of the hoist body 1. The upper cover 2 of the hoist is fixed. During the operation of the hoist body 1, the upper cover 2 of the hoist will be damaged by the operation of the hoist body 1. Through the nut 4. The cooperation between the spring 6 and the bolt gasket 7 prevents the upper cover 2 of the elevator from falling off. Compared with the traditional device, the cooperation between the spring 6 and the bolt gasket 7 makes it easier to protect the upper cover 2 of the elevator. The spring 6 buffers the force by deformation to avoid direct transmission to the outer shell or the upper cover, thereby playing the role of a "buffer" to prevent damage to the equipment. Once the spring pushes open the upper cover, the inspection personnel will quickly cooperate with the electrolysis workshop personnel to simply deal with the loose fixtures, efficiently restore the elevator to work, and avoid production delays. The presence of the spring not only improves the safety of the equipment, but also ensures the continuity and efficiency of production, and reduces electrolytic cell fluctuations and accidents.

[0024] Among them, a fixed cover 8 is fixedly installed on the top of the lifting machine upper cover 2, a connecting pipe 5 is movably installed on the outer surface of the fixed cover 8, and short bolts 9 are movably installed inside between the connecting pipe 5 and the fixed cover 8, and the short bolts 9 are in four different sizes.

[0025] By fixing the fixing cover 8 on the outer surface of the upper cover 2 of the elevator, the connecting pipe 5 is slowly moved to the outer surface of the fixing cover 8, and now the short bolts 9 are slowly screwed into the inside of the connecting pipe 5 and the fixing cover 8. There are four short bolts 9, so that the short bolts 9 can fix the fixing cover 8 and the connecting pipe 5 more stably. This is very important for the connecting pipe 5 of the elevator. It can ensure the tightness and firmness of the pipeline connection, effectively avoid loosening or falling off, and reduce the risks of leakage, breakage, etc., so as to ensure the stable operation of the elevator. The stable connection of the connecting pipe 5 reduces the downtime and maintenance time caused by pipeline problems, improves work efficiency, and extends the service life of the pipeline. At the same time, this also reduces maintenance costs and energy consumption, and improves the energy efficiency ratio of the elevator.

[0026] Among them, a fixing plate 11 is fixedly installed on the top of the hoist upper cover 2, and a hook 10 is fixedly installed on the top of the fixing plate 11, and the hooks 10 and the fixing plates 11 are grouped in pairs, and there are two groups at the top of the hoist upper cover 2.

[0027] Since the hooks 10 and the fixing plates 11 are connected in pairs, with a total of two groups on the top of the elevator cover 2, the flexibility and adaptability of the elevator are significantly enhanced by adding the hooks 10, so that it can quickly and firmly connect and fix various items to meet diverse operational needs. At the same time, the hooks 10 simplify the mounting and unloading processes, improve work efficiency, and ensure the stability of items during the lifting process, reducing safety hazards. The hooks 10 also provide additional support and fixation, enhancing the safety of the lifting process. By optimizing the design and layout of the hooks 10, the overall performance of the elevator is further improved, and the carrying capacity and stability are significantly enhanced, enabling it to cope with various challenges and achieve efficient and safe lifting operations.

[0028] The spring 6 is in the shape of six different sizes and is located between two bolt washers 7 , and the spring 6 is made of stainless steel.

[0029] Since the spring 6 is made of stainless steel and the spring 6 is in the shape of six sizes between the two bolt washers 7, the stainless steel spring 6 is highly praised for its excellent corrosion resistance. The high chromium content forms a tough chromium oxide film that effectively resists a variety of corrosive environments. At the same time, it has excellent physical properties, such as a uniform and beautiful surface, good formability and high plasticity, ensuring stable elastic deformation under load and recovery to its original shape.

[0030] Among them, the long bolts 3 and nuts 4 are grouped in pairs, and there are a total of six groups movably installed inside the elevator body 1 and the elevator upper cover 2.

[0031] The long bolts 3 and nuts 4 are arranged in pairs, with a total of two groups inside the elevator body 1 and the elevator cover 2. A strong fastening connection can be achieved through the combination of the long bolts 3 and the nuts 4. The bolts are generally cylindrical with external threads, while the nuts are annular with internal threads. When the external threads of the bolts and the internal threads of the nut are engaged with each other, they generate a large static friction force in the direction perpendicular to the threads. At the same time, since the internal and external threads are compressed and deformed when the nuts are tightened, there is also static friction along the thread direction, which enables the bolts and nuts to withstand a large vertical thread force under static conditions, thereby achieving a fastening connection.

[0032] The working principle and use process of this utility model:

[0033] The staff needs to fix the hoist cover 2 on the surface of the hoist body 1, and then slowly install the nut 4 into the long bolt 3, and then install the bolt gasket 7 on the top of the nut 4. Now, slowly install the spring 6 into the two bolt gaskets 7, and then slowly screw the long bolt 3 into the interior of the hoist body 1. Through the cooperation between the nut 4, spring 6 and bolt gasket 7, the hoist cover 2 is fixedly installed on the outer surface of the hoist body 1. The hoist cover 2 is fixed. During the operation of the hoist body 1, the hoist cover 2 will damage the hoist body 1 as the hoist body 1 runs. The cooperation between the nut 4, spring 6 and bolt gasket 7 prevents the hoist cover 2 from falling off, thereby completing the protection of the hoist cover 2.
