Description

Technical Field

[0001] This utility model relates to the field of ferromolybdenum smelting technology, specifically to a lifting assembly for ferromolybdenum ingots used in ferromolybdenum smelting. Background Technology

[0002] Ferromolybdenum, a key molybdenum additive in the steelmaking industry, involves core processes in its smelting, including high-temperature melting, water quenching, and crushing and finishing. According to industry data, ferromolybdenum smelting typically employs a metallothermic melting process. The smelted ferromolybdenum ingots then undergo water quenching to enhance their brittleness and facilitate subsequent crushing.

[0003] During the processing of ferromolybdenum ingots, lifting assemblies are required for their lifting and movement. Currently, most common lifting assemblies are lifting slings. Because lifting slings are made of synthetic fibers such as polyester and nylon, their soft surface and low coefficient of friction prevent scratching the surface of the ferromolybdenum ingots and reduce the generation of fine powder. High-quality lifting slings have a working temperature range of -40℃ to 100℃, covering the environmental requirements of ferromolybdenum smelting, and will not undergo permanent deformation under short-term high-temperature exposure. Synthetic fibers have good resistance to dust and acid mist in the metallurgical environment, and their service life is significantly longer than that of steel wire ropes.

[0004] When lifting molybdenum ingots using synthetic fiber lifting slings, multiple anti-slip rubber balls are installed on the surface of the sling to enhance frictional resistance between the sling and the ingot. While this increases frictional resistance, the connection between the rubber balls and the sling is unstable (they are mostly bonded to the sling surface via thermosetting rubber). During subsequent lifting operations, these rubber balls are prone to detaching, hindering stable lifting of the ingot. Furthermore, the constant friction between the sling's edges and the sharp edges of the ingot can cause localized edge cracking, necessitating improvements in service life and safety. Utility Model Content

[0005] The purpose of this invention is to provide a lifting assembly for ferromolybdenum ingots in ferromolybdenum smelting. This assembly employs a novel connection structure to replace the traditional rubber hot-melt bonding method, firmly fixing the anti-slip rubber balls to the surface of the lifting sling. This significantly enhances the connection stability between the anti-slip rubber balls and the lifting sling, effectively preventing the localized detachment of the anti-slip rubber balls during subsequent lifting operations. This ensures stable and reliable lifting of the ferromolybdenum ingots, protects the edges of the lifting sling on both sides, reducing the probability of fraying when rubbing against the sharp points of the ferromolybdenum ingot, significantly extending the service life of the lifting sling, and improving safety performance during use. This addresses the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting assembly for ferromolybdenum ingots in ferromolybdenum smelting, comprising: a belt body, wherein a plurality of anti-slip balls are evenly distributed on the upper surface of the belt body, and both sides of the belt body are wrapped with edge strips, the edge strips being sewn to the belt body by sewing thread, the edge strips and the belt body being spun from yarn, and the anti-slip balls being connected to the belt body by a connecting assembly.

[0007] Preferably, the connecting assembly includes: a plurality of first rings, each of which is fixedly connected to the bottom end of a plurality of anti-slip balls; a rubber post is fixedly connected to the inner wall of the first ring; the top end of the rubber post is fixedly connected to the anti-slip ball; a vertical cylinder is fixedly sleeved on the outer wall of the rubber post; an eyelet is provided on the outer side of the vertical cylinder; the eyelet is fixedly connected to the belt body; a second ring is pressed against the bottom end of the eyelet; a bolt is inserted into the bottom end of the second ring; the bolt passes through the second ring and is threadedly connected to the vertical cylinder.

[0008] Preferably, the eyelet buckle passes through the belt body via a heat-fusion hole.

[0009] Preferably, the anti-slip ball and the rubber column are integrally molded.

[0010] Preferably, the spun yarn includes: multiple strong cores, which are distributed in a warp and weft pattern inside the belt and the binding strip. Polyester fiber filaments and nylon fiber filaments are spirally wound on the outer side of the strong cores, and the polyester fiber filaments and nylon fiber filaments are twisted together.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting assembly for ferromolybdenum ingots in ferromolybdenum smelting has the following advantages over traditional technology: Through the coordinated operation of various components, stable and safe lifting of ferromolybdenum ingots in ferromolybdenum smelting is achieved. During the lifting of ferromolybdenum ingots using a sling, the operator faces the ferromolybdenum ingot with the surface of the sling containing anti-slip balls facing the ingot. During the lifting operation, parts of the sling and the anti-slip balls will directly contact the surface of the ferromolybdenum ingot. Because the anti-slip balls can significantly increase the frictional resistance between the sling and the ferromolybdenum ingot, it is convenient to carry out stable lifting operations. During this period, the anti-slip balls are installed between the sling and the sling through connecting components, which can greatly enhance the connection stability between the anti-slip balls and the lifting sling, effectively preventing the local anti-slip balls from falling off during subsequent lifting operations, and ensuring stable and reliable lifting operations of ferromolybdenum ingots. In addition, after prolonged use, when the local anti-slip ball becomes severely worn, the operator can rotate the bolt corresponding to the severely worn anti-slip ball counterclockwise to separate it from the vertical cylinder. This allows the severely worn anti-slip ball, the first ring, the rubber block, and the vertical cylinder that are fixed to it to be replaced, so as to facilitate the subsequent stable and safe hoisting operation of the ferromolybdenum ingot. In addition, the edge banding strips wrapped around the edges of the strip can protect the edges of the strip, reduce the probability of cracking when it rubs against the sharp parts of the ferromolybdenum ingot, significantly extend the service life of the strip, and improve safety performance during use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a lifting assembly for ferromolybdenum ingots in ferromolybdenum smelting, comprising: a belt body 1, a plurality of anti-slip balls 2 evenly distributed on the upper surface of the belt body 1, and edge banding strips 3 wrapped around both sides of the belt body 1. The edge banding strips 3 are sewn to the belt body 1 by sewing thread 4. Both the edge banding strips 3 and the belt body 1 are spun from yarn 5. The anti-slip balls 2 are connected to the belt body 1 by a connecting assembly.

[0017] In the specific implementation process, it is worth noting that the belt body 1, as the main load-bearing structure of the entire lifting assembly, can adapt to molybdenum ingots of different shapes and angles during lifting, reducing the risk of breakage due to excessive rigidity. Multiple anti-slip balls 2 are evenly distributed on the upper surface of the belt body 1, their distribution density carefully calculated and experimentally verified to ensure that, regardless of the contact position between the molybdenum ingot and the belt body 1 during lifting, a sufficient number of anti-slip balls 2 are in contact with the surface of the molybdenum ingot, thus providing stable and uniform friction. The material of the edge banding strip 3 matches that of the belt body 1, also possessing good wear resistance and tear resistance. Its width is determined according to the belt body 1. The thickness and usage requirements are designed to ensure that the edges of the belt body 1 are completely wrapped, effectively preventing edge wear and unraveling. The sewing thread 4 is made of high-strength nylon thread, which has high tensile strength and wear resistance, and can firmly sew the binding strip 3 to the belt body 1 together. It is not easy to break during long-term use. The spinning thread 5 serves as the basic material for the belt body 1 and the binding strip 3. Its spinning process has been optimized, which allows multiple strong cores 51 to be tightly combined. At the same time, the spiral winding and twisting connection of polyester fiber 52 and nylon fiber 53 further enhances the strength and toughness of the spinning thread 5, improving the overall performance of the belt body 1 and the binding strip 3.

[0018] Furthermore, the connecting assembly includes: multiple first rings 6, which are respectively fixed to the bottom ends of multiple anti-slip balls 2; a rubber post 7 is fixed to the inner wall of the first ring 6; the top end of the rubber post 7 is fixedly connected to the anti-slip ball 2; a vertical cylinder 8 is fixedly sleeved on the outer wall of the rubber post 7; a cornice buckle 9 is provided on the outer side of the vertical cylinder 8; the cornice buckle 9 is fixedly connected to the belt body 1; a second ring 10 is pressed against the bottom end of the cornice buckle 9; a bolt 11 is inserted into the bottom end of the second ring 10; the bolt 11 passes through the second ring 10 and is threadedly connected to the vertical cylinder 8.

[0019] In the specific implementation process, it is worth noting that the first ring 6 is made of high-strength metal materials, such as stainless steel, which has good resistance to deformation and corrosion, ensuring that it will not deform under stress during long-term use, thus guaranteeing the stability of the connection with the anti-slip ball 2. The rubber column 7 is made of high-quality rubber material, which has a certain degree of elasticity and flexibility, and can play a buffering role during lifting, reducing the rigid impact between the anti-slip ball 2 and the surface of the molybdenum ingot. At the same time, it can adapt to the surface of molybdenum ingots of different shapes, increasing the contact area and improving friction. The vertical cylinder 8 is also made of metal material, and the thread precision of its inner wall is strictly controlled to ensure that it is in close contact with the bolt 1. The threaded connection of 1 is tight and reliable, and there will be no loosening during the lifting process. The eyelet 9 is used to fix the connecting component to the belt body 1. It is made of metal and has high strength and wear resistance. It is firmly connected to the belt body 1 through the hot melt hole 12 and can withstand a large tensile force. The second ring 10 plays a supporting and positioning role. Its size matches the vertical cylinder 8 and the bolt 11 to ensure that the bolt 11 can be accurately inserted and connected to the thread of the vertical cylinder 8. The bolt 11 is made of high-strength alloy steel and has undergone heat treatment process. It has high hardness and tensile strength, which can ensure the overall connection strength of the connecting component and ensure that the anti-slip ball 2 will not fall off during the lifting process.

[0020] Furthermore, the eyelet 9 penetrates the belt body 1 through the hot-melt hole 12.

[0021] In the specific implementation process, it is worth noting that the hot melt hole 12 is made using an advanced hot melt process. The material of the belt body 1 is melted at high temperature to form a hole. This process can ensure that the edge of the hole is smooth and neat, and will not cause excessive damage to the strength of the belt body 1. When installing the eyelet 9, it is pressed into the hot melt hole 12 with a special tool so that the edge of the eyelet 9 fits tightly with the belt body 1, forming a strong connection structure.

[0022] Furthermore, the anti-slip ball 2 and the rubber column 7 are integrally molded structures.

[0023] In the specific implementation process, it is worth noting that the one-piece molding structure is achieved through special molds and injection molding processes. During production, rubber material is injected into the mold, which simultaneously forms the shape of the anti-slip ball 2 and the rubber column 7. This process ensures that there are no obvious connection gaps between the anti-slip ball 2 and the rubber column 7, improving the integrity and strength of the structure. The one-piece molding structure also ensures that the connection between the anti-slip ball 2 and the rubber column 7 is firm and reliable, and there will be no separation during lifting. This ensures that the anti-slip ball 2 can stably play its role in increasing friction. In addition, the one-piece molding structure can reduce production steps, improve production efficiency, and reduce production costs.

[0024] Furthermore, the spinning thread 5 includes: multiple strong cores 51, which are distributed in a warp and weft pattern inside the belt body 1 and the binding strip 3. Polyester fiber filaments 52 and nylon fiber filaments 53 are spirally wound on the outside of the strong cores 51, and the polyester fiber filaments 52 and nylon fiber filaments 53 are twisted together.

[0025] In the specific implementation process, it is worth noting that the interlacing distribution of multiple strong cores 51 can form a stable mesh structure. This structure can evenly distribute the force, improving the tensile strength and tear resistance of the belt body 1 and the edge strip 3. The strong cores 51 are made of high-strength fiber materials, such as aramid fiber, which has extremely high strength and modulus and is not easily broken when subjected to large tensile forces. The spiral winding and twisting connection of polyester fiber 52 and nylon fiber 53 further enhances the strength and toughness of the spun yarn 5. Polyester fiber 52 has good abrasion resistance and corrosion resistance, while nylon fiber 53 has high elasticity and resilience. The combination of the two allows the spun yarn 5 to maintain good performance in complex usage environments. At the same time, the spiral winding and twisting connection can also increase the surface area of ​​the spun yarn 5, improve the friction between it and other materials of the belt body 1 and the edge strip 3, and enable the spun yarn 5 to be more firmly integrated into the belt body 1 and the edge strip 3, thereby improving the overall structural stability.

[0026] Working principle: The belt and anti-slip balls work together to increase frictional resistance and achieve stable lifting. When hoisting ferromolybdenum ingots, the operator positions the surface of the conveyor belt 1 with the anti-slip balls 2 facing the ingot. During the hoisting operation, parts of the conveyor belt 1 and the anti-slip balls 2 will directly contact the surface of the ferromolybdenum ingot. The design of the anti-slip balls 2 significantly increases the frictional resistance between the conveyor belt 1 and the ferromolybdenum ingot. This increased friction effectively prevents the ferromolybdenum ingot from sliding relative to the conveyor belt 1 during hoisting, thus facilitating stable hoisting operations. The anti-slip balls 2 are installed on the conveyor belt 1 through a connecting component. The presence of the connecting component greatly enhances the connection stability between the anti-slip balls 2 and the conveyor belt 1, ensuring that the anti-slip balls 2 will not easily fall off the conveyor belt 1 during subsequent hoisting operations, further guaranteeing stable and reliable hoisting operations for the ferromolybdenum ingot.

[0027] The replaceable anti-slip ball design ensures long-term stable and safe lifting: After prolonged use of the lifting assembly, some anti-slip balls 2 may experience severe wear. Operators can identify severely worn anti-slip balls 2 by observing and inspecting their appearance and friction performance. When severe wear is detected, operators can rotate the bolt 11 corresponding to the severely worn anti-slip ball 2 counterclockwise. As the bolt 11 rotates, it separates from the vertical cylinder 8. Since the severely worn anti-slip ball 2 is fixed to the first ring 6, rubber column 7, and vertical cylinder 8, once the bolt 11 separates from the vertical cylinder 8, the severely worn anti-slip ball 2, along with its connected first ring 6, rubber column 7, and vertical cylinder 8, can be replaced as a whole. This replaceable design allows for timely replacement of worn anti-slip balls 2, ensuring sufficient frictional resistance between the belt 1 and the molybdenum ingot, thus facilitating stable and safe lifting operations of the molybdenum ingot and extending the effective service life of the lifting assembly.

[0028] Edge banding protects the edges of the belt to extend its service life and improve safety. The edge banding strips 3 wrapped around the edges of the belt body 1 protect the edges of the belt body 1. During hoisting operations, the edges of the belt body 1 will rub against the sharp parts of the molybdenum ingot. The edge banding strips 3 act as a protective barrier, bearing some of the friction and reducing the chance of the edges of the belt body 1 directly contacting the sharp parts of the molybdenum ingot. By reducing the probability of the edge banding strips rubbing against the sharp parts of the molybdenum ingot and causing a break, the edge banding strips 3 effectively protect the structural integrity of the belt body 1. This not only significantly extends the service life of the belt body 1 and reduces the frequency and cost of replacement due to damage to the belt body 1, but also improves the safety performance of the hoisting components during use, avoiding safety accidents such as the falling of the molybdenum ingot due to a break in the belt body 1.
