Description

Technical Field

[0001] This invention relates to the field of concrete product grinding technology, and in particular to a surface grinding and cleaning device for concrete products. Background Technology

[0002] Concrete products, such as square piles, pipe piles, and precast components, often have burrs, laitance, or unevenness on their surfaces after demolding. They need to be ground and cleaned to ensure appearance quality and dimensional accuracy, facilitating subsequent construction and installation.

[0003] Existing surface treatment methods mostly rely on manual handheld angle grinders, which are labor-intensive, inefficient, and produce inconsistent grinding quality, easily causing over-grinding or damage to the product surface. While some automated equipment can perform basic grinding of flat or regular curved surfaces, it has poor adaptability to products with different cross-sectional shapes (such as circles and rectangles) or complex structures with grooves or holes on the sides. These devices often struggle to achieve rapid and accurate centering of products of different sizes, and cannot adaptively conform the grinding tool to recessed areas, resulting in incomplete cleaning. Furthermore, dust and debris generated during grinding, if not collected and disposed of promptly, will cause environmental pollution. Therefore, there is an urgent need for a device that can automatically adapt to concrete products of different specifications and complex shapes, achieving efficient, precise, and clean surface grinding and cleaning. We propose a surface grinding and cleaning device for concrete products. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0016] 1. This invention, by setting up a conveying mechanism and a grinding mechanism, can ensure an integrated and automated structural composition, enabling grinding operations on the surface of concrete products of different shapes and sizes. In addition, the recessed parts on the side can also be ground efficiently and adaptively. During grinding, a centralized space is cleaned uniformly, realizing full automation of the entire process from material loading, centering and positioning, conveying, multi-face grinding, special treatment of recesses, rinsing and cleaning to finished product unloading. This improves the degree of automation, processing accuracy and cleanliness and environmental protection, and reduces labor costs and operational risks.

[0017] 2. This invention features a grinding mechanism consisting of two sets of mirror-arranged mounting plates with drive plates offset by 90 degrees. The guide groove and connecting frame drive the movable plates to move synchronously towards or away from each other, allowing four grinding belts to simultaneously and precisely adhere to or leave the side of the product from four directions. This enables uniform circumferential grinding for both circular and rectangular cross-sections. Furthermore, the grinding belts are mounted via a second movable frame with elastic support, allowing them to passively adapt to the grinding operation on the product surface.

[0018] 3. By setting up an electric slide, a second electric push rod, an electric gripper, and a support roller shaft and their surrounding components, when encountering a depression, the internal electric slide, electric push rod, and electric gripper can work together to drive the support roller shaft to actively push out, forcing the grinding belt to deform and tightly fit the inner wall of the depression. This achieves active adaptive grinding of complex shapes and solves the problem that traditional equipment cannot effectively handle depressions.

[0019] 4. By setting up a working cylinder, ring frame and nozzle, this invention can ensure the integration of grinding and cleaning. Specifically, the surface of the product is high-pressure washed during or after grinding to remove grinding debris and dust in time. Wastewater and waste residue are collected into the collection box through the bottom discharge chute, realizing the centralized collection and treatment of waste materials and avoiding dust flying.

[0020] 5. By setting up a detection block, a support spring, and their surrounding components, when the support roller supports the inner side of the grinding belt, the movable block slides inside the slot and squeezes the support spring to deform it. By detecting the pressure generated by the support spring through the detection block, it can be determined whether the support roller is in place, thus ensuring the best grinding effect.

[0021] 6. By setting up a conveying mechanism and an electric push rod driven shear-type lifting frame structure, the present invention can smoothly adjust the height of the conveying frame and the material, ensuring that the central axis of the product to be polished is precisely aligned with the core position of the polishing mechanism. With the constraint plate that can be adjusted horizontally and vertically, it can quickly adapt to and clamp cylindrical or rectangular columnar products with different cross-sectional dimensions, ensuring the stability of the material during the conveying and polishing process.

Detailed Implementation

[0037] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0038] Example: Figure 1 As shown, a surface grinding and cleaning device for concrete products includes two sets of conveying mechanisms 1 and a grinding mechanism 2. The two sets of conveying mechanisms 1 are mirror images of each other on both sides of the grinding mechanism 2. The conveying mechanisms 1 can adjust the height of the material and constrain its center position. The grinding mechanism 2 can grind different materials and perform the same matching grinding operation on recessed areas.

[0039] like Figures 2 to 4As shown, the conveying mechanism 1 includes a base frame 11, with a conveying frame 12 mounted on the upper side of the base frame 11. The conveying frame 12 is a rectangular frame with multiple sets of rollers synchronously mounted on its sides, and a micro motor is mounted on its side for driving, enabling all rollers to roll and convey materials. A first lifting frame 13 and a second lifting frame 14 are symmetrically arranged between the base frame 11 and the conveying frame 12. The center positions of the first lifting frame 13 and the second lifting frame 14 are rotatably connected by a rotating shaft. One side of the first lifting frame 13 and the second lifting frame 14 are respectively rotatably connected and mounted on the side of the conveying frame 12 and the base frame 11. A constraint frame 15 is symmetrically fixedly mounted on the side of the base frame 11 and the conveying frame 12 corresponding to the other end of the first lifting frame 13 and the second lifting frame 14. The constraint frame 15 is a U-shaped frame, and movable wheels 151 are slidably mounted inside the constraint frame 15, and the movable wheels 151 are respectively fixedly mounted on the opposite side. The movable wheel 151 is a round wheel located on the side of the first lifting frame 13 and the second lifting frame 14. A mating frame 152 is rotatably installed between the first lifting frame 13. The mating frame 152 is a rectangular frame. A first electric push rod 16 is fixedly installed on the upper side of the base frame 11, and the output end of the first electric push rod 16 is fixedly installed on the side of the mating frame 152. Specifically, the mating frame 152 can be pushed and pulled by the first electric push rod 16. The mating frame 152 pushes the first lifting frame 13 to move. Simultaneously, the movable wheel 151 slides in the restraint position inside the restraint frame 15. The first lifting frame 13 and the second lifting frame 14 perform shear-like lifting and lowering, so that the conveying frame 12 can be lifted and lowered on the upper side of the base frame 11. In this way, when the material is placed on the upper side of the conveying frame 12, the conveying frame 12 can drive the material to adjust its position, and the side rollers of the conveying frame 12 can transport the material.

[0040] A constraint plate 17 is mirror-imagely disposed on the upper side of the conveyor frame 12. The constraint plate 17 is a folded plate. A fixing rod 18 is vertically fixedly installed symmetrically on the upper side of the conveyor frame 12 corresponding to the position of the constraint plate 17. The fixing rod 18 is a U-shaped frame. A first movable frame 182 is horizontally movably installed inside the fixing rod 18 and is fixedly connected to the side of the constraint plate 17. The first movable frame 182 is a rectangular rod. A first movable slot 181 is opened through the side of the fixing rod 18, and a second movable slot 183 is opened through the side of the first movable frame 182. The first movable slot 181... Both the first movable groove 181 and the second movable groove 183 are rectangular grooves. Bolts 19 are provided on the side of the fixed rod 18, and the bolts 19 pass through the first movable groove 181 and the second movable groove 183 to lock the fixed rod 18 and the first movable frame 182 synchronously. Specifically, after loosening the bolts 19, the first movable frame 182 can move in both directions of lifting and stretching inside the fixed rod 18. The first movable frame 182 can drive the constraint plate 17 to adjust its position. Then, tightening the bolts 19 can synchronously fix the fixed rod 18 and the first movable frame 182, and the constraint plate 17 can laterally constrain the position of the material.

[0041] like Figure 2 and Figures 5 to 12 As shown, the grinding mechanism 2 includes a working cylinder 21 disposed between two sets of conveying mechanisms 1. The working cylinder 21 is a cylindrical cylinder. A ring frame 211 is symmetrically fixedly installed on the inner side of the working cylinder 21. The ring frame 211 is a hollow circular ring frame. The ring frame 211 is connected to an external water supply module through a pipe. Spray nozzles 212 are fixedly arranged in an equidistant array on the inner circumference of the ring frame 211, and the spray nozzles 212 penetrate into the interior of the ring frame 211. The spray nozzles 212 are multi-angle spray nozzles 212. A discharge groove 213 is opened through the bottom wall of the inner side of the working cylinder 21. A collection box 214 is provided on the lower side of the working cylinder 21. Corresponding to the discharge chute 213, the collection box 214 is a rectangular box with a hollowed-out upper side. Mounting plates 22 are fixedly mounted mirror-imagely on both sides of the working cylinder 21. Mounting plates 22 are circular plates, with a through-groove 221 at the center of their side surface. The through-groove 221 is a rectangular groove. An inner cavity 222 is formed inside the mounting plate 22, which is an annular cavity. A sliding groove 223 is symmetrically formed on the wall of the inner cavity 222, penetrating the mounting plate 22. The sliding grooves 223 on the sides of the two sets of mounting plates 22 are staggered by ninety degrees. The sliding grooves 223 are rectangular grooves. A movable part is installed inside the sliding groove 223. The drive plate 23 is a circular ring plate with teeth on the outer side. A gear 24 is meshed on the side of the drive plate 23 and is movably disposed inside the mounting plate 22. A first motor 241 is fixedly mounted on the side of the mounting plate 22, and the output end of the first motor 241 passes through the mounting plate 22 and is fixedly connected to the side of the gear 24. Guide grooves 231, which are arc-shaped, are circumferentially arrayed and equidistant from the guide groove 223 on the side of the drive plate 23. A guide block 232, which is a cylindrical block, is movably mounted inside the guide groove 231. A connecting frame 233 is fixedly installed on the side and slides inside the slide groove 223 and extends out partially. The connecting frame 233 is an "L" shaped frame. Specifically, the first motor 241 drives the gear 24 to rotate. The gear 24 meshes with the drive plate 23, causing the guide block 232 to slide inside the guide groove 231. At the same time, it drives the connecting frame 233 to slide inside the slide groove 223 to adjust its position. This allows the two sets of connecting frames 233 on the side of the mounting plate 22 to move synchronously. The positions of the other two sets of connecting frames 233 on the side of the mounting plate 22 are staggered by ninety degrees, which allows the material to be moved closer and further away from all four sides synchronously.

[0042] A movable plate 25 is fixedly installed on the side of the connecting frame 233 away from the drive plate 23. The movable plate 25 is a "C"-shaped plate. A constraint groove 224 is symmetrically opened on the side of the mounting plate 22, and the movable plate 25 is movably disposed within the constraint groove 224. The constraint groove 224 is a rectangular groove. A constraint rod 234, a cylindrical rod, is fixedly installed inside the constraint groove 224, penetrating the movable plate 25. A third movable groove 251, also rectangular, is symmetrically opened on the side of the movable plate 25, penetrating it. A second movable frame 252 is movably installed inside the slot 251 and is located below the movable plate 25. The second movable frame 252 consists of a rectangular block and a "C"-shaped frame. A guide rod 253, which passes through the second movable frame 252, is fixedly installed inside the third movable slot 251. The guide rod 253 is a cylindrical rod. A support cylinder 254 is movably sleeved on the side of the guide rod 253 and is fixedly connected between the side of the second movable frame 252 and the wall of the movable plate 25. The support cylinder 254 is a corrugated circular elastic material. The cylinder has a roller frame 255 rotatably mounted inside the second movable frame 252. The roller frame 255 is a U-shaped splined cylindrical frame. A second motor 256 is fixedly mounted on the side of the second movable frame 252, and the output end of the second motor 256 is fixedly connected to the side of the roller frame 255. A grinding belt 257 is engaged with the side of the roller frame 255. The grinding belt 257 is an "O"-shaped belt with a diamond coating on the side. Specifically, the connecting frame 233 can drive the movable plate 25 to move in position, and the movable plate 25 slides synchronously inside the constraint groove 224. Constrained by the constraint rod 234, the grinding belt 257 can then be attached to the side of the material. When the grinding belt 257 is attached to the side of the material, the roller frame 255 is pulled, which allows the second movable frame 252 to slide inside the third movable groove 251. The second movable frame 252 is constrained by the guide rod 253 and slides. The support cylinder 254 provides elastic support for the second movable frame 252, so that the grinding belt 257 can be elastically attached to the side of the material. The second motor 256 drives the roller frame 255 to rotate, which drives the grinding belt 257 to perform grinding operations on the material.

[0043] A power supply module 26, which is a rechargeable battery, is fixedly installed at the center of the lower side of the movable plate 25. A sliding table 261 is symmetrically fixedly installed on the lower side of the movable plate 25. A second electric push rod 262 is vertically fixedly installed on the side of the slider of the sliding table 261. A fixing frame 263 is fixedly installed at the output end of the second electric push rod 262, and the fixing frame 263 is located inside the grinding belt 257. The fixing frame 263 is a concave frame. A [missing information - likely a component or component] is fixedly installed on the lower side of the fixing frame 263. The electric gripper 27, electric slide table 261, second electric push rod 262, and electric gripper 27 are connected to the power supply module 26 via wires. A clamping frame 28 is fixedly mounted mirror-image on the side of the slider of the electric gripper 27. The clamping frame 28 is a foldable "C"-shaped frame with a through slot 281 on its side. A support roller 29 is provided on the side of the clamping frame 28, with both ends of the support roller 29 movably positioned inside the slot 281. The support roller 29 is a cross-shaped cylindrical shaft. Movable blocks 282 are movably sleeved on both sides of the support roller shaft 29 and slidably installed inside the slot 281. The movable blocks 282 are rectangular blocks with round holes on their sides. A detection block 283, which is a pressure sensor, is fixedly installed through the wall of the slot 281. A support spring 284 is fixedly connected between the movable blocks 282 and the sides of the detection blocks 283. Specifically, the second electric push rod 262 can be moved by the electric slide table 261. The electric push rod 262 can push and pull the fixed frame 263 to move its position. The fixed frame 263 can then drive the electric gripper 27 to move along two axes inside the grinding belt 257. The electric gripper 27 can control the clamping frame 28 to clamp and separate a certain distance, thus adjusting the distance between the clamping frames 28. The support roller shaft 29 can then be pressed against the inner side of the grinding belt 257, actively causing the second movable frame 252 to slide elastically. This allows the grinding belt 257 to better fit against the side of the material for grinding operations.

[0044] Furthermore, a surface grinding and cleaning device for concrete products also includes concrete product materials, such as... Figure 13 As shown, the concrete product material includes a first product 31 and a second product 32. The first product 31 is a cylindrical concrete product, and the second product 32 is a rectangular columnar concrete product. A slot 33 is provided on the side of the second product 32. The slot 33 constrains the first product 31 and the second product 32 to form during the casting process and is used for subsequent positioning and installation of the concrete product.

[0045] Working principle:

[0046] Before polishing: First, place the corresponding first product 31 or second product 32 on the upper side of the conveyor frame 12. Move the position of the mating frame 152 by pushing and pulling the first electric push rod 16, so that the movable wheel 151 is constrained and slides inside the constraint frame 15. The first lifting frame 13 and the second lifting frame 14 perform shear-like cross lifting, and the conveyor frame 12 can drive the first product 31 or second product 32 to adjust the height position, so that the center position of the first product 31 or second product 32 corresponds to the center position of the mating groove 221.

[0047] The second step is to loosen the bolt 19 so that the first movable frame 182 can move in both directions inside the fixed rod 18, so that the constraint plate 17 can fit and constrain the side of the first product 31 or the second product 32. Then, tighten the bolt 19 to lock and fix the fixed rod 18 and the first movable frame 182. The constraint plate 17 constrains the center position of the first product 31 or the second product 32 to completely correspond to the center position of the first motor 241.

[0048] During polishing: First, side polishing. The first product 31 or the second product 32 is conveyed by the conveyor frame 12 through the mating groove 221 to the inner position of the working cylinder 21. The first motor 241 on the side of the first set of mounting plates 22 drives the gear 24 to mesh with the drive plate 23. The guide block 232 slides within the guide groove 231 under constraint. The connecting frame 233 slides within the slide groove 223, causing the movable plate 25 to move closer together. At this time, the corresponding polishing belt 257 can adhere to the side of the first product 31 or the second product 32. When the roller frame 255 is pulled, the second movable frame 252 slides elastically inside the third movable groove 251 under the support of the support cylinder 254. The polishing belt 257 is elastically attached to the side of the first product 31 and the second product 32. The second motor 256 drives the roller frame 255 to rotate, so that the polishing belt 257 can polish the side of the first product 31 or the second product 32. Similarly, the other side of the second set of mounting plates 22 can be polished by performing the same operation on the other side of the first product 31 or the second product 32.

[0049] The electric slide table 261 drives the electric gripper 27 to center it inside the grinding belt 257. The electric gripper 27 moves the clamping frame 28 away from the ground to a suitable position. The second electric push rod 262 pushes the electric gripper 27 so that the support roller shaft 29 fits against the inside of the grinding belt 257. When the first product 31 is being ground, the support roller shaft 29 can ensure multi-point support on the inside of the grinding belt 257, allowing the grinding belt 257 to deform and fit better against the side of the first product 31. When the second product 32 is being ground, the support roller... Shaft 29 can ensure support for the inner side of the grinding belt 257, making the grinding belt 257 fit more closely to the side of the second product 32, thus ensuring the grinding effect on the sides of the first product 31 and the second product 32; in addition, when the support roller shaft 29 supports the inner side of the grinding belt 257, the movable block 282 slides inside the slot 281 and squeezes the support spring 284 to deform it. By detecting the pressure generated by the support spring 284 by the detection block 283, it can be determined whether the support of the support roller shaft 29 is in place;

[0050] The second step is grinding and cleaning. When grinding the first product 31 or the second product 32, water is pressurized and supplied through the external water supply module. After the water flows through the inner side of the ring frame 211, it is sprayed in multiple directions through the nozzle 212. This can rinse and clean the side of the first product 31 or the second product 32. The waste liquid after rinsing flows out of the discharge trough 213 through the working cylinder 21 and finally flows into the collection box 214 for centralized collection.

[0051] The third step, as Figure 14 As shown, in the irregular mating grinding, when the first product 31 or the second product 32 has a groove 33 on its side, when the grinding belt 257 is grinding normally, after reaching the groove 33 position, by inputting data in advance, the external controller controls the electric slide table 261 to drive the electric gripper 27 to move to the center position of the corresponding groove 33. The electric gripper 27 controls the clamping frame 28 so that the support roller shaft 29 corresponds to the two walls of the groove 33. Then, the second electric push rod 262 pushes the electric gripper 27 so that the support roller shaft 29 actively squeezes the inside of the grinding belt 257, so that the grinding belt 257 is attached to each wall of the groove 33. The pressure change is detected by the detection block 283 to know that the grinding belt 257 is in place. The second motor 256 drives the roller frame 255 to rotate the grinding belt 257 to complete the grinding operation at the groove 33. In this way, the automatic grinding operation of the groove 33 at different positions on the side of the first product 31 or the second product 32 can be realized.

[0052] After grinding: The height of the conveyor frame 12 and the position of the constraint plate 17 in the other conveyor mechanism 1 are adjusted in the same way as the first conveyor mechanism 1. The first product 31 or the second product 32 after grinding extends to the upper position of the conveyor frame 12 through another set of mating grooves 221. The first product 31 or the second product 32 continues to be conveyed through the conveyor frame 12 for gradual discharge operation. Through the joint action of the conveyor frame 12 and the constraint plate 17 in the two conveyor mechanisms 1, the position of the first product 31 or the second product 32 can be ensured to be stable during grinding, so as to complete the automated grinding in coordination with the grinding mechanism 2. This device can realize the automated grinding and centralized rinsing and cleaning of materials of different specifications.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
