Description

Technical Field

[0001] This utility model relates to the field of sand making machine technology, and in particular to a reinforced structure for a vertical double-roll sand making machine. Background Technology

[0002] During the production process of a vertical double-roll crusher, there are certain requirements for the feed particle size. However, due to reasons such as misoperation and equipment failure, a small amount of stones exceeding the particle size range may enter the double-roll crusher. This requires stress analysis of the key parts of the entire machine and places higher demands on the strength and rigidity of the key parts of the entire equipment.

[0003] Currently, the main methods for eliminating internal stress are stress-relief annealing and mechanical vibration. Among them, stress-relief annealing increases costs and can cause workpiece deformation, so it is not recommended. While mechanical vibration is more ideal, as it can fully release internal stress by preventing cracks in critical parts within one month of production, this method requires the strength and stiffness of critical parts to exceed the conventional design range by ≥25%, while also avoiding a significant increase in costs. Conventional ear plates and frame beam structures are difficult to meet these requirements.

[0004] Therefore, there is an urgent need for a reinforcement structure for vertical double-roll crushing machines that can add reinforcement structures in dangerous areas, thereby increasing the strength and rigidity of the entire equipment. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] refer to Figure 1-13 A specific embodiment of this utility model provides a reinforcing structure for a vertical double-roll crusher, which is installed on the ear plate assembly and frame beam assembly of the vertical double-roll crusher. The ear plate assembly includes two sets of oppositely arranged outer ear plates 3 and inner ear plates 5, including: Ear plate reinforcement and first danger zone A: The first danger zone A is formed on all outer ear plates 3 and inner ear plates 5 respectively, and the ear plate reinforcement is installed on the first danger zone A; The frame beam reinforcement, the second dangerous area B and the third dangerous area C are formed at the connection of the frame beam assembly. The second dangerous area B is formed at the connection of the frame beam assembly. The third dangerous area C is formed on the inner side of the right angle of the frame beam assembly. The frame beam reinforcement is installed on the second dangerous area B and the third dangerous area C.

[0020] Currently, the main methods for eliminating internal stress are pressure-relief annealing and mechanical vibration. Pressure-relief annealing is unsuitable due to increased costs and the risk of workpiece deformation. While mechanical vibration is more ideal, allowing critical components to remain crack-free for up to a month during production to fully release internal stress, it requires strength and stiffness exceeding conventional design limits by at least 25%, while also avoiding significant cost increases. Conventional ear plate and frame beam structures cannot meet these requirements. This application employs reinforced structures for critical components of the ear plate and frame beam assemblies. Specifically, ear plate reinforcements are installed in the first hazardous area A, and frame beam reinforcements are installed in the second and third hazardous areas C. This setup is cost-effective and effectively enhances the strength of the ear plate and frame beam assemblies, thereby improving the overall strength of the vertical double-roll crusher. Overall, by adding reinforcement structures in the hazardous areas, the strength and stiffness of the entire equipment are improved.

[0021] Among them, the outer ear plate 3 and the inner ear plate 5 are each provided with two sets, such as Figure 3As shown.

[0022] The scheme is further optimized. The ear plate reinforcement installed on the outer ear plate 3 includes a steel pipe 4, which is coaxially fixedly connected to the outer ear plate 3.

[0023] refer to Figure 3 , 6 The steel pipe 4 has an outer diameter of 299mm, a thickness of 16mm, and an axial length of 40mm. The steel pipe 4 is welded to the outer ear plate 3. The welding end of the steel pipe 4 has a 6x45° welding bevel. With this setting, the steel pipe 4 becomes part of the outer ear plate 3, thereby strengthening the strength and rigidity of the outer ear plate 3 by about 30%. The steel pipe 4 is made from scrap material, which can save costs.

[0024] refer to Figure 4 Only the effect of setting the first danger zone A on the outer ear plate 3 is shown. The effect of setting the first danger zone A on the inner ear plate 5 is the same. Figure 4 Same as shown.

[0025] The scheme is further optimized. The ear plate reinforcement installed on the inner ear plate 5 includes an annular steel plate 6, which is coaxially fixedly connected to the inner ear plate 5. Welding holes 7 and annular steel plate 6 are provided with several welding holes 7 at equal intervals in the circumferential direction. Annular steel plate 6 is welded to inner ear plate 5 through all welding holes 7.

[0026] refer to Figure 3 , 5 The annular steel plate 6 is made of 16mm thick steel, using scrap material. The annular steel plate 6 has 6 sets of welding holes 7 evenly spaced around its circumference. The inner diameter of each welding hole 7 is 18mm. By welding inside the welding holes 7, the annular steel plate 6 is connected to the inner ear plate 5 to form an integral structure, which strengthens the strength and rigidity of the inner ear plate 5 by about 35%. Welding inside the welding holes 7 is equivalent to riveting, which is simpler to manufacture and saves time and cost compared to rivets.

[0027] Further optimization of the scheme: the frame beam assembly includes an upper frame beam body 1 and a lower frame beam body 2. A second danger zone B is formed at the connection between the upper frame beam body 1 and the lower frame beam body 2, and a third danger zone C is formed on the inner side of the right angle of the upper frame beam body 1.

[0028] refer to Figure 1 , 7 The second danger zone B is located at the connection between the upper frame beam body 1 and the lower frame beam body 2, and the third danger zone C is located inside the right angle of the upper frame beam body 1.

[0029] Further optimization of the design includes the following reinforcement components for the frame beam located in the second hazardous area B: Flange 12 is fixed (welded) at the connection between the upper frame beam body 1 and the lower frame beam body 2. The flanges 12 at the connection are arranged opposite to each other and are fixedly connected by bolts. The third stiffening plate 11 is fixedly connected to the connection between the upper frame beam body 1 and the flange 12, and the connection between the lower frame beam body 2 and the flange 12.

[0030] The standard wall thickness for existing square tubes is 12mm. Increasing the wall thickness, such as to 16mm, requires custom manufacturing, significantly increasing costs. (Reference) Figure 1 , 7 13. In this application, the upper frame beam body 1 and the lower frame beam body 2 are both made of 300x300 square tubing with a wall thickness of 12mm. Based on this, at critical locations, namely the second hazardous area B, flanges 12 connect the upper frame beam body 1 and the lower frame beam body 2. Third stiffening plates 11 are fixedly connected at the connections between the upper frame beam body 1 and the flanges 12, and at the connections between the lower frame beam body 2 and the flanges 12, respectively. This configuration is suitable for longer and thinner square tubing frames. The flanges 12 are 40mm thick, and the third stiffening plates 11 are right-angled triangular stiffening plates with a width of 70mm and a height three times the width, which is 210mm. The strength and stiffness of the second hazardous area B are increased by approximately 33%.

[0031] The scheme is further optimized. The frame beam reinforcement located in the third dangerous area C includes a first stiffening plate 9 and a second stiffening plate 10. The two sets of first stiffening plates 9 are welded side by side to the inner side of the right angle of the upper frame beam body 1. The first stiffening plate 9 and the second stiffening plate 10 are welded side by side to the inner side of the right angle of the upper frame beam body 1. The plate 8 is vertically arranged and fixedly connected between the first stiffening plate 9 and the upper frame beam body 1, and between the second stiffening plate 10 and the upper frame beam body 1.

[0032] refer to Figure 1 , 7 10, 11, where the inner side of the right angle of the main body 1 of the upper frame beam adopts a double stiffening plate structure, and the size of the first stiffening plate 9 is larger than the size of the second stiffening plate 10; for the third dangerous area C with weak structural strength, a double row of first stiffening plates 9 is adopted, and for the third dangerous area C with moderate structural strength, a combination of first stiffening plate 9 and second stiffening plate 10 is adopted. This setting can improve the strength and stiffness of the third dangerous area C by about 33%.
