Description

Technical Field

[0001] This utility model belongs to the field of tailing tooling technology and also to the field of hoisting, specifically relating to a tailing tooling for realizing the flipping and erection of cylindrical equipment. Background Technology

[0002] As my country's industrial level continues to reach new heights, cylindrical equipment such as chimneys and reaction towers in nuclear power, thermal power, and petrochemical engineering fields are rapidly evolving towards large-scale modularization. The significant increase in the size and weight of cylindrical equipment places stringent demands on transportation and hoisting processes. Currently, cylindrical equipment is generally transported horizontally, but it is installed vertically, often requiring it to be turned over and erected. To meet installation and maintenance needs, cylindrical equipment is typically equipped with ladders and walkways. If installation is carried out after the cylindrical equipment is erected, extensive scaffolding is required, leading to frequent overlapping operations and high construction costs. If installation is completed in a horizontal position beforehand, the upper walkways, ladders, and slings are prone to interference when using traditional binding methods for vertical erection. Once interference occurs, the relevant components must be removed and reassembled after the equipment is erected, a repetitive process that is not only cumbersome but also significantly increases workload. Therefore, a vertical erection tooling is needed. When the equipment is tilted and erected, the vertical erection tooling is attached to the tooling to prevent interference between the tooling and the equipment. After erection, the tooling is removed, reducing construction costs and the risks of working at heights. Furthermore, the tooling can be reused and installed on the next piece of equipment to be tilted and erected. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides a tailing fixture for achieving the tilting and erection of cylindrical equipment. This fixture solves the problem of interference between the tailing rigging and the equipment structure during the tilting and erection of cylindrical equipment. Specifically, it effectively solves the problems of high cost, long time consumption, easy interference, and high safety risks in the existing cylindrical equipment tilting and erection process, enabling safe, efficient, and low-cost cylindrical equipment tilting and erection operations, and meeting the lifting requirements of cylindrical equipment.

[0004] To overcome the shortcomings of existing technologies, this utility model provides a solution for a tailing fixture used to achieve the tilting and verticalization of cylindrical equipment, as detailed below: A tailing fixture for tilting and uprighting cylindrical equipment, comprising: Two main beams are set vertically; Tail-end lifting lugs are welded at specific positions on the main beam. The tail-end lifting lugs are used for hanging tail-end slings and are the connection hub between the tooling and the hook of the tail-end crane. Reinforcing plates are welded to the key stress-bearing locations of the main beam.

[0005] Furthermore, the main beams are made of I-beams.

[0006] Furthermore, two I-beams are set vertically in parallel.

[0007] Furthermore, a connecting plate is welded onto the main beam. The connecting plate is used to connect the tailing fixture for turning the cylindrical equipment upright and the cylindrical equipment.

[0008] Furthermore, the material for the sling lugs is carbon steel plate.

[0009] Furthermore, the sling hanger is formed by welding a main board and several reinforcing ribs together, and then welding it to the main beam for fixation.

[0010] Furthermore, there are four reinforcing ribs, with two of them symmetrically distributed on both sides of the motherboard along with the other two.

[0011] Furthermore, the motherboard has through-hole lifting lugs.

[0012] Furthermore, connecting plates are welded to the corresponding positions of the main beam and holes are drilled to form through bolt holes. Four reinforcing plates are then welded to the connecting plates.

[0013] Furthermore, the flange face of the cylindrical equipment is annular.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model eliminates interference, reduces labor intensity and risk. The tooling eliminates the interference between the tailing rigging and the equipment structure, and eliminates the need to remove walkways, ladders and other components on the equipment. It avoids high-altitude operations during dismantling and restoration, significantly reduces the labor intensity of construction workers and improves the inherent safety level of the operation.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 3 As shown, the present invention provides a tailing fixture for achieving the tilting and verticalization of a cylindrical device, comprising: Two main beams 1 are set vertically; Tail-end lifting lug 2 is welded at a specific position on the main beam 1. Tail-end lifting lug 2 is used for hanging the tail-end sling. Tail-end lifting lug 2 is an important connection hub between the tooling and the hook of the tail-end crane, ensuring that the pulling force of the tail-end crane can be smoothly transmitted to the cylindrical equipment. Reinforcing plates 3 are welded at key stress locations of the main beam 1.

[0020] Two vertically arranged main beams 1 form the main load-bearing frame of the tailing fixture used to achieve the tilting and erection of the cylindrical equipment. The overall strength is enhanced by welding reinforcing plates 3. These reinforcing plates act as "skeletal reinforcements" for the fixture, significantly improving the overall load-bearing capacity and stability of the fixture, enabling it to withstand the enormous forces generated during the tilting of the cylindrical equipment.

[0021] In a preferred but non-limiting embodiment of this utility model, the main beam 1 is an I-beam.

[0022] The advantages of I-beam structures are: 1. Superior mechanical properties and load-bearing capacity High bending strength: The cross-sectional shape of H-beams (wide flanges and high web) gives them extremely high section modulus and moment of inertia when subjected to vertical bending loads. This perfectly matches the working conditions of tooling subjected to huge bending moments when flipping cylindrical equipment, and can effectively resist bending deformation.

[0023] High strength-to-weight ratio: While providing the same load-bearing capacity, H-beams can be lighter than solid steel blocks or certain other steel sections. This facilitates the lifting and handling of the tooling itself and reduces the additional load applied to the equipment flanges.

[0024] 2. Good structural stability Lateral stability: The wide upper and lower flanges provide good lateral stability for the tooling, which can resist lateral forces or unexpected swings that may occur during the flipping process and prevent the tooling from becoming unstable.

[0025] Clear stress distribution: The regular geometry of H-beams and the clear stress flow lines facilitate engineers to perform accurate stress analysis and calculations, ensuring safe and reliable design.

[0026] 3. Facilitates connection and processing Providing an ideal welding plane: The wide, flat flange surface of H-beams greatly facilitates the welding of connecting plates, reinforcing plates, and tail lugs. Welds can be placed on a flat surface, which not only allows for a larger weld area to improve connection strength but also ensures weld quality.

[0027] Easy to standardize and customize: H-beams are standard profiles with ample market supply and a complete range of sizes, facilitating procurement and cost control. They are also easy to cut, drill, and perform secondary processing, allowing for flexible adjustment of the welding position and drilling pattern of the connecting plates according to the dimensions of different equipment flanges.

[0028] 4. Economy and practicality Low manufacturing cost: The use of standard profiles combined with welding technology avoids complex casting or forging processes, greatly reducing the manufacturing and maintenance costs of tooling.

[0029] Durable and reusable: The H-beams are made of uniform material, have a robust structure, and are durable. This makes the entire fixture a sturdy, reusable device, meeting the requirement mentioned in the text that it can be installed on the next piece of equipment, thus offering good economic benefits.

[0030] In summary, the selection of H-beams as the main beam material is the core foundation for achieving the comprehensive technical effects of high strength, high stability, ease of fabrication and connection, and economic practicality in this tailing fixture. It ensures that the fixture can safely and reliably bear the complex loads during the tilting and erection of the cylindrical equipment, making it an ideal structural choice for achieving the invention's objectives. H-beams possess excellent mechanical properties, meeting the strength requirements of the fixture under complex stress conditions. In a preferred but non-limiting embodiment of this utility model, two I-beams 1 are arranged vertically in parallel.

[0031] Two parallel I-beams form the main load-bearing frame, effectively dispersing and bearing the bending moment and torque generated during the rotation of the cylindrical equipment by utilizing the high bending strength and stiffness of the I-beams themselves.

[0032] In use, two I-beams are arranged in parallel, and reinforcing plates are welded to their key stress-bearing parts to improve the load-bearing capacity and stability of the tooling; the tailing lugs are welded to specific positions on the tooling to connect the tailing slings.

[0033] In a preferred but non-limiting embodiment of this utility model, a connecting plate 4 is also welded onto the main beam 1. The connecting plate 4 is used to connect the tailing fixture for the cylindrical equipment to the cylindrical equipment and to the cylindrical equipment.

[0034] In a preferred but non-limiting embodiment of this utility model, the material of the sling lug 2 is carbon steel plate.

[0035] The advantages of using carbon steel plate as the material for the sling lug 2 are as follows: 1. Excellent comprehensive mechanical properties High strength and toughness: Carbon steel plates (usually referring to Q235B, Q345B, etc.) have a good balance of strength and toughness. This ensures that the lifting lugs can withstand the huge tensile loads transmitted by the tail sling, preventing breakage due to insufficient strength, while its toughness can absorb impact energy, avoiding brittle failure under dynamic loads such as start-stop or swaying.

[0036] Reliable load-bearing capacity: As a component that directly transmits force, the reliability of the lifting lug is crucial. The mature and stable mechanical properties of carbon steel plates provide the lifting lug with a safe and predictable load-bearing capacity.

[0037] 2. Excellent processability and machinability Easy to cut and shape: Carbon steel plates can be easily processed into the required shapes (such as main plates and reinforcing plates) through flame cutting, plasma cutting or laser cutting. The manufacturing process is simple and the cost is low.

[0038] Excellent weldability: Carbon steel plates (especially low-carbon steel) are among the best weldable metal materials. This makes: The lifting lug assembly itself is easy to mold: it can easily weld "one main board" and "four reinforcing ribs" into a sturdy whole with high quality.

[0039] Reliable connection with the main beam: The formed lifting lug assembly can be firmly welded to the H-beam main beam with high quality, forming a strong metallurgical bond and ensuring the effective transmission of force from the rigging to the lifting lug to the main beam.

[0040] 3. Achieving high strength through structural design Although carbon steel plates themselves are not the strongest, the structural design of "one main plate welded with four reinforcing ribs" creates a highly reinforced and extremely rigid composite component. This "box-shaped" or "rib-reinforced" structure greatly enhances the bending and tensile stiffness of the lifting lug, making its load-bearing capacity far superior to that of a simple flat plate, perfectly meeting the stress requirements of the tooling.

[0041] 4. Economy and versatility Low cost: Carbon steel plate is one of the most common and economical structural steel materials, with ample supply, which can effectively control the manufacturing cost of tooling.

[0042] High versatility: Its performance meets the stress requirements of most such tooling, eliminating the need to use more expensive high-strength alloy steel, making the tooling economically viable for widespread adoption.

[0043] In summary, the core technological advantage of using carbon steel plates for lifting lugs lies in leveraging the excellent strength, toughness, and weldability of carbon steel. Through a rational structural design (main board + reinforcing ribs), a key load-bearing component with high load-bearing capacity, reliable connection, and low cost can be manufactured. This ensures that the tension of the tail sling can be safely and efficiently transmitted to the main tooling body, making it a reliable link in the entire force transmission chain.

[0044] In a preferred but non-limiting embodiment of this utility model, the sling lug 2 is formed by welding a main board and several reinforcing ribs 5 together, and then welding and fixing it to the main beam 1.

[0045] In a preferred but non-limiting embodiment of this utility model, the number of reinforcing ribs 5 is four, and two of the four reinforcing ribs 5 are symmetrically distributed on both sides of the motherboard along with the other two reinforcing ribs 5.

[0046] In a preferred but non-limiting embodiment of this utility model, a through-type lifting lug hole 6 is provided on the motherboard.

[0047] In a preferred but non-limiting embodiment of this invention, based on the dimensions of the cylindrical equipment flange, a connecting plate 4 is welded to the corresponding position of the main beam 1, and through bolt holes 7 are drilled. Four reinforcing plates 3 are welded to the connecting plate to enhance the load-bearing capacity. This allows for subsequent connection to the cylindrical equipment flange 9 via nuts 11 and high-strength bolts 10. The position and dimensional accuracy of the drilled holes are consistent with the bolt holes 8 on the cylindrical equipment flange 9. High-strength bolts are used for tooling installation. The bolts are tightened to the specified torque to ensure a tight connection and prevent loosening during subsequent operations.

[0048] In a preferred but non-limiting embodiment of this utility model, the flange surface 9 of the cylindrical equipment is annular.

[0049] This utility model has the following characteristics: 1. Main Structural Design: The core structure consists of two parallel I-beams as the main beams, with reinforcing plates welded to key load-bearing areas. This structural design combines the high load-bearing capacity of the I-beams with the strengthening effect of the reinforcing plates to enhance the overall strength and stability of the tooling. Unlike conventional single-support structures, this is a crucial component ensuring the reliability of the tooling during the tilting of the cylindrical equipment. 2. Tail-Slip Lifting Lugs: Tail-slip lifting lugs are welded to specific locations on the tooling. These lugs are made of carbon steel plates, with a main plate welded to the main beam and four reinforcing ribs welded together. This lug structure connects to the tail-slip rigging, allowing the crane's pulling force to be effectively transferred to the cylindrical equipment. Its unique welded assembly structure and installation location design provide a reliable point of leverage for the tilting of the cylindrical equipment. 3. Customized connecting plate design: Based on the flange dimensions of the cylindrical equipment, the connecting plate is welded and drilled at the corresponding position on the main beam. This customized connecting plate design enables precise docking between the tooling and the cylindrical equipment. High-strength bolts ensure connection strength and stability, making it a key component for reliable connection between the tooling and the cylindrical equipment.

[0050] 4. A reinforcing plate is welded to the stress concentration area of ​​the connecting plate and fixedly connected to the connecting plate to enhance the overall strength and stability of the tooling.

[0051] 5. The interference-free construction method utilizes tooling independent of the cylindrical equipment structure, ensuring that the tailing rigging does not interfere with the cylindrical equipment body, upper walkway slabs, ladders, or other structures, allowing construction to proceed without dismantling related components of the cylindrical equipment. This innovative construction method solves the problem of interference between rigging and the cylindrical equipment structure in traditional construction, improving construction efficiency and safety.

[0052] During the fabrication of the tailing fixture used to tilt and erect the cylindrical equipment, the main beam is made of H-beams, and the chute lugs are machined from carbon steel plates. These lugs are formed by welding a main plate and four reinforcing ribs together, and then welded to the main beam for fixation. Based on the flange dimensions of the cylindrical equipment, connecting plates are welded and drilled at corresponding positions on the main beam. Four reinforcing plates are then welded to the connecting plates to increase load-bearing capacity. The tailing fixture used to tilt and erect the cylindrical equipment is typically located next to the ladder 12 on the walkway platform 13. When installing the tailing fixture used to tilt and erect the cylindrical equipment, first inspect the fixture, which consists of I-beams, reinforcing plates, and tailing lugs, to ensure that the welds are secure and the structure is intact. Use a truck crane to lift the two auxiliary fixtures to the installation position on the equipment flange face, connect them with high-strength bolts, and tighten them to the specified torque. Then, connect the tailing crane hook to the fixture lugs using slings and shackles, and adjust the crane and slings.

[0053] The cylindrical equipment is tilted and erected. The slings and shackles are connected to the hook of the tailing crane and the lifting lugs of the tooling. This tooling effectively transfers the crane's pulling force to the cylindrical equipment. Because the tailing tooling used to tilt and erect the cylindrical equipment is independent of the equipment structure, it cleverly avoids interference between the tailing slings and the equipment body, upper walkway, ladders, and other structures, eliminating the need to dismantle related parts of the equipment. The crane and slings are adjusted, the crane is started, and with the help of the tooling and the main lifting point, the cylindrical equipment is tilted and erected from its horizontal position.

[0054] The beneficial effects of this utility model are as follows: 1. This utility model eliminates interference, reduces labor intensity and risk. The tooling eliminates the interference between the tailing rigging and the equipment structure, and eliminates the need to remove walkways, ladders and other components on the equipment. It avoids high-altitude operations during dismantling and restoration, significantly reduces the labor intensity of construction workers and improves the inherent safety level of the operation.

[0055] 2. This utility model has a simple structure and strong applicability. The tooling structure mainly consists of I-beams, reinforcing plates, and lifting lugs, making the structure concise and clear, and the manufacturing process is not complicated. At the same time, it is highly practical and can adapt to the flipping needs of various similar structures. Furthermore, compared to traditional processes and other complex tooling, its promotion cost is low, making it easy to promote and apply within the industry.

[0056] 3. The tooling structure of this utility model is reasonably designed. The selection of materials and processing precision of the main beam, lifting lugs and connecting plates meet the construction requirements. Through strict welding process and quality inspection, the overall strength and stability of the tooling are guaranteed, and it can reliably withstand various loads during the rotation of the cylindrical equipment.

[0057] The present invention has been described above by way of example. Those skilled in the art should understand that the present disclosure is not limited to the embodiments described above, and various changes, modifications and substitutions can be made without departing from the scope of the present invention.
