Description

Technical Field

[0001] This application relates to the field of steel grinding technology, and more specifically, to a high-strength steel grinding device. Background Technology

[0002] In modern bridge construction, plate-shaped high-strength steel is widely used in the main structure of bridges due to its excellent mechanical properties. The surface quality of the steel directly affects the fatigue life, welding strength and corrosion resistance of the bridge structure. Therefore, grinding is a key process in the processing of high-strength steel, which requires the removal of surface oxide scale, rust and processing marks, while ensuring that the surface roughness meets the design requirements.

[0003] Currently, grinding equipment for high-strength steel on the market mainly suffers from the following problems: Firstly, the grinding pressure control of traditional grinding equipment is not precise enough. High-strength steel has high hardness, and excessive grinding pressure can easily cause scratches, deformation, and other damage to the steel surface. Insufficient pressure, on the other hand, fails to achieve the desired grinding effect, especially for grinding the upper and lower surfaces of the steel, where the large surface area of ​​plate-shaped high-strength steel makes it more susceptible to damage. Secondly, most grinding equipment lacks effective dust collection devices. The large amount of metal dust generated during the grinding of high-strength steel not only pollutes the working environment but also harms the health of operators. Therefore, there is an urgent need to develop a high-strength steel grinding equipment that can precisely control grinding pressure and effectively collect grinding dust to meet the modern industrial demand for high-quality grinding of high-strength steel.

[0038] like Figure 1-4As shown, this application provides a high-strength steel grinding device, including a grinding box 1, a conveying mechanism 2, a grinding system 3, a pressure sensing system 4, and a controller 5. The grinding box 1 has conveying through holes penetrating both sides of the grinding box 1. The conveying mechanism 2 is located on the outer sides of both ends of the conveying through holes and on the grinding box 1, used to convey the high-strength steel to be ground. The grinding system 3 is located inside the grinding box 1 and consists of a first grinding mechanism 31 and a second grinding mechanism 32. The first grinding mechanism 31 is used to grind the upper and lower surfaces of the steel, and the second grinding mechanism 32 is used to grind the left and right surfaces of the steel. The right side is ground; the pressure sensing system 4 is installed on the first grinding mechanism 31 to monitor the contact pressure between the first grinding component and the steel surface in real time; the controller 5 is installed on one side of the grinding box 1 and is electrically connected to the conveying component 21, the first grinding mechanism 31, the second grinding mechanism 32 and the pressure sensing system 4. The controller 5 automatically adjusts the operating parameters of the conveying component 21, the first grinding mechanism 31 and the second grinding mechanism 32 based on the feedback signal of the pressure sensing system 4. When grinding high-strength steel, the steel to be ground is conveyed by the two ends of the conveying through hole of the grinding box 1. The outer conveyor mechanism 2 feeds the steel into the grinding box 1. After entering the grinding box 1, the first grinding mechanism 31 grinds the upper and lower surfaces of the steel, while the second grinding mechanism 32 grinds the left and right sides of the steel. During the grinding process of the first grinding mechanism 31, the pressure sensing system 4 monitors the contact pressure between the first grinding mechanism 31 and the steel surface in real time and converts the pressure data into an electrical signal, which is then fed back to the controller 5. After receiving the signal, the controller 5 analyzes and processes the data, and automatically adjusts the conveying speed of the conveyor mechanism 2 and the first grinding mechanism 32 based on the difference between the preset pressure standard and the current feedback pressure. The grinding pressure of the grinding mechanism 31 ensures that the grinding process is always carried out under suitable working conditions until the grinding of the steel is completed. Through the coordinated work of various systems, the steel is ground in all directions. The closed-loop control system formed by the pressure sensing system 4 and the controller 5 can accurately adjust the grinding pressure to avoid damage to the steel surface caused by improper pressure, thus effectively improving the grinding quality. The setting of the grinding box 1 can effectively prevent the diffusion of a large amount of metal dust generated during the grinding of high-strength steel, protect the working environment, reduce dust leakage, and reduce the harm to the health of operators.

[0039] like Figure 1 As shown, the conveying mechanism 2 includes a conveying component 21, which includes a conveying frame 211 and an electric conveying roller 212. The conveying frame 211 is fixed on the grinding box 1, and the electric conveying roller 212 is rotatably mounted on the conveying frame 211. The rotational speed of the electric conveying roller 212 can be adjusted according to the actual grinding requirements, and it can flexibly adapt to the conveying of high-strength steel of different specifications and grinding process requirements. The electric conveying roller 212 is rotatably mounted on the conveying frame 211 through bearings.

[0040] like Figure 1As shown, the conveying mechanism 2 also includes four independent anti-deviation components 22. The four anti-deviation components 22 are symmetrically distributed on the outer sides of both ends of the conveying through hole, with two components at each end. The anti-deviation component 22 includes a baffle 221 and an anti-deviation electric cylinder 222. The anti-deviation electric cylinder 222 is fixed on the grinding box 1, and the baffle 221 is fixed on the telescopic rod of the anti-deviation electric cylinder 222. During the transportation of high-strength steel by the conveying mechanism 2, the four anti-deviation components 22 distributed on the outer sides of both ends of the conveying through hole play a role. The anti-deviation electric cylinder 222 drives the baffle 221 to extend and maintain a distance of 2-5mm from the side of the high-strength steel to prevent the high-strength steel from deviating excessively during the conveying process of the electric conveying roller 212.

[0041] like Figure 1-4As shown, the top of the grinding box 1 is provided with a suitable box cover 11. The first grinding mechanism 31 includes an upper grinding assembly 311 and a lower grinding assembly 312. The upper grinding assembly 311 includes an upper grinding roller 3111, an upper roller mounting frame 3112, a lifting frame 3113, and a lifting cylinder 3114. The lifting cylinder 3114 is fixedly mounted on the top of the box cover 11, and the lifting frame 3113 is located below the box cover 11. The telescopic rod of the lifting cylinder 3114 moves through the box cover 11 and is fixedly connected to the lifting frame 3113. The top of the upper roller mounting frame 3112 is symmetrically provided with first guide posts 6. The 6-movable through-lifting frame 3113 has a first anti-detachment plate 61 fixed at the upper end of the first guide column 6, and a first spring 7 sleeved on the first guide column 6. The first spring 7 is located between the upper roller mounting frame 3112 and the lifting frame 3113. The upper grinding roller 3111 is rotatably mounted on the upper roller mounting frame 3112. The lower grinding assembly 312 includes a lower grinding roller 3121 and a lower roller mounting frame 3122. The lower roller mounting frame 3122 is fixed to the bottom of the box cover 11, and the lower grinding roller 3121 is rotatably mounted on the lower roller mounting frame 3122. During high-strength steel grinding operations, the lifting electric cylinder 3114... Fixed to the top of the cover 11, when grinding of the steel is required, the telescopic rod of the lifting cylinder 3114 extends downward, moving through the cover 11 to drive the lifting frame 3113 downward, thereby pushing the upper roller mounting frame 3112 along with the upper grinding roller 3111 downward until the upper grinding roller 3111 contacts the upper surface of the steel. During the contact process, the first guide post 6 plays a guiding role, ensuring that the upper roller mounting frame 3112 moves smoothly downward and preventing deviation. At the same time, the first spring 7 is sleeved on the first guide post 6, located between the upper roller mounting frame 3112 and the lifting frame 3113. When the steel surface... When the surface is uneven or the grinding pressure changes, the first spring 7 can buffer and adjust through its own compression or extension, so that the upper grinding roller 3111 maintains a suitable contact pressure with the steel surface. The lower grinding roller 3121 is fixed to the bottom of the box cover 11 through the lower roller mounting bracket 3122, and cooperates with the upper grinding roller 3111 to grind the upper and lower surfaces of the steel at the same time. The first grinding mechanism 31 realizes the flexible adjustment of the height of the upper grinding roller 3111 through the cooperation of the lifting electric cylinder 3114 and the lifting frame 3113, which can adapt to the grinding needs of high-strength steel of different thicknesses and improve the versatility of the equipment.

[0042] like Figure 2-4As shown, the second polishing mechanism 32 includes a front polishing assembly 321, a rear polishing assembly 322, and a drive assembly 323. A groove 12 is provided at the bottom of the cover 11. The front polishing assembly 321 and the rear polishing assembly 322 are symmetrically arranged within the groove 12. The drive assembly 323 includes a drive motor 3231 and a bidirectional screw 3232. The bidirectional screw 3232 is rotatably mounted at the bottom of the cover 11, and the drive motor 3231 is fixed to the bottom of the cover 11. The output shaft of the drive motor 3231 is connected to one end of the bidirectional screw 3232. When the bidirectional screw 3232 rotates, it can drive the front grinding assembly 321 and the rear grinding assembly 322 to move closer or further apart. When the second grinding mechanism 32 is working, the drive motor 3231 fixed at the bottom of the cover 11 starts and drives the bidirectional screw 3232 to rotate, thereby driving the front grinding assembly 321 and the rear grinding assembly 322 to move closer together and grind the high-strength steel passing between the front grinding assembly 321 and the rear grinding assembly 322. It can flexibly adapt to the grinding of high-strength steel of different widths and specifications, further improving the versatility of the equipment.

[0043] like Figure 2-4 As shown, both the front grinding assembly 321 and the rear grinding assembly 322 include a movable frame 3211 and a grinding plate 3212. The upper end of the movable frame 3211 is slidably connected to the slide groove 12. The movable frame 3211 is provided with a threaded hole adapted to the bidirectional screw 3232. The movable frame 3211 is threadedly connected to the bidirectional screw 3232 through the threaded hole. A second guide post 8 is symmetrically fixed on one side of the grinding plate 3212. The second guide post 8 movably passes through the movable frame 3211. A second anti-detachment plate 81 is fixed on the end of the second guide post 8 away from the grinding plate 3212. A second spring 9 is sleeved on the second guide post 8. The second spring 9 is located between the movable frame 3211 and the grinding plate 3212. A grinding layer 10 is provided on the side of the grinding plate 3212 away from the second guide post 8. When the drive motor 3231 drives the bidirectional screw 3212... When the screw 3232 rotates, the moving frame 3211 of the front grinding assembly 321 and the rear grinding assembly 322, which are threadedly connected to the bidirectional screw 3232, will move closer or further apart along the sliding groove 12 at the bottom of the cover 11 due to the threaded transmission principle. This adjusts the distance between the two front grinding assemblies 321 and the rear grinding assembly 322 to accommodate high-strength steel of different widths. During grinding, the front and rear sides of the high-strength steel rub against the grinding layer 10 on the grinding plate 3212 during the conveying process, thus achieving grinding. The design of the second guide post 8 and the second spring 9 enables the grinding plate 3212 to automatically adjust the pressure during the grinding process, effectively avoiding damage to the steel surface due to excessive pressure or poor grinding effect due to insufficient pressure, significantly improving the grinding quality and precision.

[0044] like Figure 2-4As shown, the pressure sensing system 4 includes a limiting ring 41, a pressure sensor 42, a first connecting post 43, a second connecting post 44, and a connecting spring 45. The limiting ring 41 is fixed to the upper roller mounting frame 3112. The pressure sensor 42 is located inside the limiting ring 41 and abuts against the upper roller mounting frame 3112. The first connecting post 43 is fixed to the top of the pressure sensor 42. The second connecting post 44 is located above the first connecting post 43 and fixed to the lifting frame 3113. The connecting spring 45 is located between the pressure sensor 42 and the lifting frame 3113 and is sleeved on the first connecting post 43 and the second connecting post 44. During the grinding of high-strength steel, the upper grinding roller 3111 is connected to the pressure sensing system 4 through the upper roller mounting frame 3112. When the grinding operation begins, the upper grinding roller 3111 contacts the steel surface and generates pressure. This pressure is transmitted to the pressure sensor 42 inside the limiting ring 41 through the upper roller mounting frame 3112. 2. When pressure sensor 42 is subjected to force, it deforms and converts the pressure signal into an electrical signal. At the same time, the distance between the first connecting column 43 at the top of pressure sensor 42 and the second connecting column 44 on the lifting frame 3113 changes due to the pressure change. The connecting spring 45 sleeved on the two connecting columns also compresses or extends accordingly. The connecting spring 45 plays a role in buffering and assisting in the transmission of pressure, enabling pressure sensor 42 to stably sense pressure changes. Pressure sensor 42 transmits the collected pressure electrical signal to controller 5. Controller 5 compares and analyzes the preset pressure value with the feedback signal, and then adjusts components such as lifting cylinder 3114 to control the lifting and lowering of the upper grinding roller 3111 and the grinding pressure. This achieves real-time monitoring and precise control of grinding pressure, ensuring that the pressure on high-strength steel is within a reasonable range during grinding, effectively avoiding damage to the steel surface or over-grinding due to improper pressure, and improving grinding quality.

[0045] like Figure 1-4 As shown, the electric conveyor roller 212, the upper grinding roller 3111, and the lower grinding roller 3121 are all electric rollers. A grinding layer 10 is fixed on the outer surface of the upper grinding roller 3111 and the lower grinding roller 3121. The electric rollers are existing technology and will not be described in detail here. Designing the electric conveyor roller 212, the upper grinding roller 3111, and the lower grinding roller 3121 as electric rollers simplifies the transmission structure of the equipment and reduces additional transmission components.

[0046] like Figure 1-4As shown, the controller 5 is electrically connected to the electric conveyor roller 212, the anti-deviation electric cylinder 222, the lifting electric cylinder 3114, the upper grinding roller 3111, the lower grinding roller 3121, the drive motor 3231, and the pressure sensor 42. During the grinding of high-strength steel, the pressure sensor 42 monitors the contact pressure between the upper grinding roller 3111 and the steel surface in real time and converts the pressure data into an electrical signal, which is then transmitted to the controller 5. The controller 5 analyzes and processes the pressure signal. If the pressure is higher or lower than the preset value, the controller 5 controls the lifting electric cylinder 3114 to adjust the height of the upper grinding roller 3111 to change the grinding pressure. At the same time, according to the grinding process requirements, the controller 5 can control the rotation speed of the electric conveyor roller 212 to adjust the conveying speed of the steel and ensure uniform grinding. The electrical connection between the controller 5 and each component forms an automated closed-loop control system, realizing precise adjustment of the grinding pressure.

[0047] like Figure 2-4 As shown, there are two first grinding mechanisms 31, which are symmetrically arranged inside the grinding box 1. The second grinding mechanism 32 is located between the two first grinding mechanisms 31. A dust discharge port is provided on the lower part of one side of the box, and a baffle 221 is installed at the dust discharge port. A flexible dustproof cloth 14 is fixed inside the grinding box 1 on the inner side of the conveying through hole. Transparent windows 15 are provided on the left and right sides of the grinding box 1. The dust generated during the grinding process is affected by gravity and airflow and gathers at the bottom of the box. When it is necessary to clean the dust, the baffle 13 at the dust discharge port can be pulled out to discharge the dust for centralized treatment. The flexible dustproof cloth 14 inside the conveying through hole can effectively prevent the dust from escaping from the conveying through hole, maintain the dust environment inside the grinding box 1, and at the same time, it does not affect the normal conveying of steel. While ensuring the continuous operation of grinding, it can achieve effective control of dust. The two symmetrically distributed first grinding mechanisms 31, together with the second grinding mechanism 32, improve grinding efficiency and grinding uniformity, and ensure better surface treatment effect of steel.

[0048] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
