Description

Technical Field

[0001] This utility model relates to the field of chain rigging technology, specifically a high-temperature resistant chain rigging. Background Technology

[0002] Chain slings, as a commonly used lifting and traction tool, are widely used in metallurgy, mining, construction, and high-temperature industries. They mainly consist of several interlocking links forming a chain, with a hook at the bottom for easy connection and lifting operations. Traditional chain slings are typically made of ordinary steel or alloy materials and, after surface treatment, are used for lifting operations in ambient temperatures. These slings have a simple structure, mature manufacturing process, and high load-bearing capacity and service life.

[0003] However, with the increasing demands of industrial production for high-temperature operating environments, the performance of traditional chain slings under high-temperature conditions has gradually become inadequate. Ordinary steel is prone to softening and deformation in high-temperature environments, leading to a significant decrease in its torsional resistance and structural stability, and even the risk of fracture. Simultaneously, traditional slings have limited corrosion and wear resistance, making them susceptible to corrosion and wear in high-temperature, highly corrosive environments, shortening their service life and increasing maintenance costs. Furthermore, traditional chain slings struggle to effectively disperse and transfer torsional stress under high-temperature conditions, easily leading to localized strain concentration, inducing metal fatigue, and reducing overall torsional deformation resistance.

[0004] Therefore, there is an urgent need to develop chain slings with excellent high-temperature resistance and strong resistance to torsional deformation to meet the requirements for safe and reliable operation in extreme high-temperature environments. This requires innovation in material selection and structural design to improve the overall performance of the slings in high-temperature environments and ensure their safety and durability in high-temperature industrial applications. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a high-temperature resistant chain rigging to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant chain rigging, comprising a chain and hooks composed of several interlocking links, each link being provided with a reinforcing member, specifically including sleeves fitted onto vertical columnar structures on both sides of the link, and five reinforcing discs distributed equidistantly from top to bottom, the sleeves on both sides correspondingly penetrating the interior of the five reinforcing discs and being fixedly connected, a central connecting block being provided at the center between adjacent upper and lower reinforcing discs, and side connecting blocks being provided between the non-sleeves connecting ends of adjacent upper and lower reinforcing discs.

[0007] As a preferred technical solution of this utility model, the outer surface of the cable ring is coated with a high-temperature resistant and wear-resistant coating.

[0008] As a preferred technical solution of this utility model, the sleeves and cable rings on both sides inside each reinforcing member are connected by welding.

[0009] As a preferred technical solution of this utility model, each central connecting block and the upper and lower reinforcing discs are connected by welding.

[0010] As a preferred technical solution of this utility model, each side connecting block and the upper and lower reinforcing discs are connected by welding.

[0011] As a preferred technical solution of this utility model, both the reinforcing member and the cable ring are made of ultra-high temperature resistant alloy material.

[0012] As a preferred technical solution of this utility model, the hook is specifically installed on the lowest grommets inside the chain.

[0013] Compared with the prior art, this utility model provides a high-temperature resistant chain rigging, which has the following beneficial effects: This chain sling utilizes high-temperature resistant alloy material for its grommets and a high-temperature resistant, wear-resistant coating, forming a robust and efficient first line of defense. This significantly improves the grommets' corrosion and wear resistance in extreme high-temperature environments, extending the chain sling's service life. More importantly, the special reinforcement design on the grommets, through the sleeve and five vertically equidistant annular reinforcing discs, forms a three-dimensional, multi-layered reinforcement frame. This structure, connected by welding the central and side connecting blocks, creates a continuous and stable reinforced chain, effectively enhancing the overall structural rigidity and stability.

[0014] This multi-layered, multi-directional reinforcement structure effectively disperses and transmits torsional stress at high temperatures, preventing localized plastic deformation and metal fatigue damage caused by torque concentration, thereby significantly improving the torsional deformation resistance of the cable ring. The reinforcement components are made of ultra-high temperature resistant alloy materials, ensuring excellent mechanical properties and structural integrity at high temperatures and avoiding safety hazards caused by material degradation. The hook is strategically installed at the bottom of the chain to ensure the stability and safety of the hoisting operation.

[0015] In summary, this chain sling, through its innovative multi-layered reinforced structural design and superior material selection, not only significantly improves the corrosion and wear resistance of the sling links in high-temperature environments, but also, crucially, enhances the sling's resistance to torsional deformation. This effectively solves the performance degradation problem caused by metal fatigue in traditional chain slings during high-temperature operations. This design greatly improves the overall safety and durability of the chain sling, making it suitable for lifting operations in high-temperature industrial environments and possessing broad application value.

If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them.

[0021] Please see Figure 1-5 The chain rigging consists of several interlocking links 1 forming a chain, with a hook 3 installed at the bottom of the chain. Each link 1 is reinforced by a specially designed reinforcing member 2, which effectively improves the structural stability of each link 1 when exposed to high temperatures, and also effectively improves the torsional resistance of the entire link 1.

[0022] Each cable ring 1 has its outer surface coated with a high-temperature and wear-resistant coating 11 to improve its corrosion and wear resistance in extreme high-temperature environments. The cable ring 1 is made of an ultra-high temperature resistant alloy material to ensure its structural stability in high-temperature environments.

[0023] The reinforcing member 2 comprises two main parts: a sleeve 21 and reinforcing discs 22. The sleeve 21 is a vertical columnar structure that fits onto corresponding positions on both sides of the cable ring 1 and is fixedly connected to the cable ring 1 by welding. The sleeve 21 extends through the interior of the five reinforcing discs 22, ensuring that the reinforcing member 2 is firmly connected to the cable ring 1.

[0024] The reinforcing discs 22 are ring-shaped and equidistantly distributed along the vertical direction, with a total of five discs arranged sequentially from top to bottom. Each reinforcing disc 22 has a central connecting block 23 at its center, which is welded to the adjacent reinforcing discs 22 to form a continuous reinforcing chain, improving the overall resistance to deformation and high temperature resistance.

[0025] Side connecting blocks 24 are provided between adjacent reinforcing discs 22 and between the through ends of the non-sleeve fittings 21, and are fixedly connected to the reinforcing discs 22 by welding. These side connecting blocks 24 serve to connect the reinforcing discs and enhance the stability of the overall structure.

[0026] All the integral structures in the reinforcing member 2, including the sleeve 21, reinforcing disc 22, central connecting block 23 and side connecting block 24, are made of ultra-high temperature resistant alloy materials to ensure performance stability and structural integrity in high temperature environments.

[0027] The hook 3 is installed on the bottommost sling 1 of the chain, which facilitates connection and hanging operations and ensures that the chain sling has good load-bearing capacity and safety during use.

[0028] The working principle of this chain rigging, which is resistant to high temperatures and torsional deformation, is as follows: When the chain sling operates in a high-temperature environment, the cable ring 1, made of ultra-high temperature resistant alloy material, forms the first protective barrier through a high-temperature resistant and wear-resistant coating 11 sprayed on its outer surface, effectively resisting high-temperature corrosion and wear. Simultaneously, the reinforcing member system 2 welded to each cable ring 1 plays a crucial role—the sleeve 21, as a vertical columnar connecting structure, passes through five equidistant annular reinforcing discs 22 distributed vertically, forming a three-dimensional reinforcing frame. These reinforcing discs 22 are welded together by a central connecting block 23 to form a continuous reinforcing chain, while the side connecting blocks 24 located at the non-sleeve 21 connection ends between adjacent reinforcing discs 22 further enhance the overall rigidity and stability. When the cable ring 1 is subjected to torsional force, this multi-layered reinforcing structure, composed of the sleeve 21, reinforcing discs 22, central connecting block 23, and side connecting block 24, can effectively disperse and transfer stress, preventing deformation caused by localized stress concentration. The entire reinforcing component 2 is made of ultra-high temperature resistant alloy material to ensure the consistency of material properties and structural integrity under extreme high temperature environment, thereby enabling the chain rigging to maintain the structural stability of the cable ring 1 in high temperature environment while effectively improving the resistance to torsional deformation.
