Description

Technical Field

[0001] This utility model relates to the field of grinding devices, and in particular to a grinding device for the surface of concrete blocks used in concrete impermeability tests. Background Technology

[0002] Concrete permeability testing is a key test item for evaluating concrete durability. Its core purpose is to determine the concrete's ability to resist penetration under the pressure of water or other liquids. This indicator is directly related to the service life and safety performance of building structures (such as basements, pools, and tunnels) in long-term contact with water or humid environments. During the test, the surface smoothness and gloss of the concrete block significantly affect the accuracy of the results. If the concrete block surface has unevenness, honeycomb texture, or residual impurities, it will lead to poor sealing during the test, causing pressurized water to leak from surface gaps instead of penetrating through the internal pores of the concrete. This will distort the experimental data and fail to truly reflect the concrete's permeability resistance. Therefore, before conducting concrete permeability testing, a specialized concrete block surface grinding device must be used to grind the test surface of the concrete block to ensure that its surface meets the required smoothness and cleanliness standards for the test.

[0003] When grinding concrete blocks using a concrete block surface grinding device for concrete impermeability testing, a large amount of concrete dust is generated. This dust mainly originates from the high-speed friction between the grinding wheel and the concrete block surface. The dust permeates the experimental environment, causing irritation to the respiratory tract and eyes of operators, and long-term exposure may pose occupational health risks. Furthermore, the dust adheres to the equipment surface, experimental platform, and surrounding environment, increasing the difficulty of cleaning and maintenance. Therefore, this application proposes a concrete block surface grinding device for concrete impermeability testing to solve the above problems. Utility Model Content

[0004] The main purpose of this invention is to provide a surface grinding device for concrete blocks used in concrete impermeability testing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A concrete block surface grinding device for concrete impermeability testing includes a base. A clamp is fixedly installed on the upper end of the base. The clamp includes two clamping plates. Two support columns are symmetrically fixedly installed on the upper ends of the two clamping plates. A dust collection component is sleeved on the upper part of the clamping plates and on the two support columns. The dust collection component consists of an arc-shaped gathering plate, a connecting tube, a connecting sleeve, an annular connector, a rotating sleeve, and a protruding locking block. The connecting tube is fixedly inserted into the arc-shaped gathering plate from the outside to the inside. There are two connecting sleeves symmetrically fixedly installed on the outer wall of the arc-shaped gathering plate. There are two annular connectors fixedly installed on the upper ends of the two connecting sleeves respectively. There are two rotating sleeves rotatably installed on the two annular connectors respectively. There are two protruding locking blocks fixedly installed on the inner walls of the two rotating sleeves respectively. The annular connectors and rotating sleeves are also sleeved on the support columns.

[0006] Preferably, a lifting base is fixedly installed at the upper end of the equipment base and behind the clamp, a horizontal drive structure is fixedly installed on the lifting base, and a grinding wheel assembly is fixedly installed on the horizontal drive structure.

[0007] Preferably, the clamp is located below the grinding wheel assembly. The clamp also includes a base plate, a support plate, and a lead screw. The base plate is fixedly installed on the upper end of the equipment base. There are two support plates, which are symmetrically fixedly installed on the upper end of the base plate. The two clamping plates are respectively located between the two support plates. There are two lead screws, which are respectively installed on the two support plates, and the lead screws are rotatably connected to the outer end of the clamping plates.

[0008] Preferably, the outer wall of the support column is provided with a plurality of longitudinally uniform limiting grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing a dust-collecting assembly above the clamping plate of the fixture, consisting of an arc-shaped gathering plate, a connecting pipe, a connecting sleeve, an annular connector, a rotating sleeve, and a protruding locking block, and in conjunction with a dust collection device, the arc-shaped gathering plate can collect the concrete dust generated during grinding operations, and then suck it into the dust collection device through the connecting pipe. This effectively reduces dust dispersion, lowers the irritation to the respiratory tract and eyes of operators and reduces occupational health risks, while also reducing dust adhesion to equipment and the environment, thus simplifying cleaning and maintenance. Furthermore, by installing a support column with several limiting grooves on the outer wall at the upper end of the clamping plate of the fixture, the support column engages with the rotating sleeve with protruding locking blocks on the dust-collecting assembly. Rotating the rotating sleeve allows the protruding locking blocks to disengage from or engage with the limiting grooves, facilitating the adjustment of the height of the dust-collecting assembly on the support column. This adapts it to concrete blocks of different heights to be ground, ensuring stable dust collection and improving the flexibility and practicality of the device. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a concrete block surface grinding device for concrete impermeability testing includes a base 1. A clamp 2 is fixedly installed on the upper end of the base 1. The clamp 2 includes two clamping plates 11. Two support columns 3 are symmetrically fixedly installed on the upper ends of the two clamping plates 11. A dust collection component 4 is sleeved above the clamping plates 11 and on the two support columns 3. The dust collection component 4 consists of an arc-shaped gathering plate 13, a connecting tube 14, a connecting sleeve 15, an annular connector 17, a rotating sleeve 18, and a protruding locking block 20. The connecting tube 14 is fixedly inserted into the arc-shaped gathering plate 13 from the outside in. There are two connecting sleeves 15, which are symmetrically fixedly installed on the outer wall of the arc-shaped gathering plate 13. There are two annular connectors 17, which are fixedly installed on the upper ends of the two connecting sleeves 15 respectively. There are two rotating sleeves 18, which are rotatably installed on the two annular connectors 17 respectively. There are two protruding locking blocks 20, which are fixedly installed on the inner walls of the two rotating sleeves 18 respectively. The annular connectors 17 and rotating sleeves 18 are also sleeved on the support column 3. By installing a dust collection assembly 4 above the clamping plate 11 of the fixture 2, consisting of an arc-shaped gathering plate 13, a connecting pipe 14, a connecting sleeve 15, an annular connector 17, a rotating sleeve 18, and a protruding locking block 20, and in conjunction with a dust collection device, the concrete dust generated during grinding operations can be gathered by the arc-shaped gathering plate 13 and then sucked into the dust collection device through the connecting pipe 14. This effectively reduces dust dispersion, lowers the irritation to the respiratory tract and eyes of operators, and reduces occupational health risks, while also reducing dust impact on equipment. The dust collection component adheres to the environment, reducing the difficulty of cleaning and maintenance. By setting a support column 3 with several limiting grooves 12 on the outer wall of the upper end of the clamping plate 11 of the clamp 2, the support column 3 is engaged with the rotating sleeve 18 with protruding locking blocks 20 on the dust collection component 4. Rotating the rotating sleeve 18 can make the protruding locking blocks 20 disengage from or lock into the limiting grooves 12, thereby facilitating the adjustment of the height of the dust collection component 4 on the support column 3, so as to adapt it to concrete blocks of different heights to be ground, ensuring stable dust collection effect and improving the flexibility and practicality of the device.

[0016] Specifically, a lifting base 5 is fixedly installed on the upper end of the equipment base 1 and behind the clamp 2. A horizontal drive structure 6 is fixedly installed on the lifting base 5, and a grinding wheel assembly 7 is fixedly installed on the horizontal drive structure 6. The clamp 2 is located below the grinding wheel assembly 7. The clamp 2 also includes a base plate 8, a support plate 9, and screw rods 10. The base plate 8 is fixedly installed on the upper end of the equipment base 1. There are two support plates 9, which are symmetrically fixedly installed on the upper end of the base plate 8. Two clamping plates 11 are located between the two support plates 9. There are two screw rods 10, which are respectively installed on the two support plates 9. The screw rods 10 are rotatably connected to the outer ends of the clamping plates 11. In the concrete impermeability test, this concrete block surface grinding device is used to grind... When grinding concrete blocks, the concrete block to be ground is first placed between the two clamping plates 11 of the clamp 2. Then, the screw 10, which is mounted on the support plate 9 and rotatably connected to the outer end of the clamping plate 11, is rotated. The screw 10 pushes the two clamping plates 11 closer to each other until the clamping plates 11 clamp and fix the concrete block. Then, the lifting base 5 and the horizontal drive structure 6 are activated. The height of the horizontal drive structure 6 and the grinding wheel assembly 7 mounted on the horizontal drive structure 6 are adjusted by the lifting base 5 so that the grinding end of the grinding wheel assembly 7 is close to the surface of the concrete block to be ground. Then, the horizontal drive structure 6 drives the grinding wheel assembly 7 to move in the horizontal direction, and the grinding wheel assembly 7 is used to grind the surface of the concrete block.

[0017] Specifically, several limiting grooves 12 are evenly spaced longitudinally on the outer wall of the support column 3. The connecting sleeve 15 on the dust collection assembly 4 has mounting holes 16, which are movably fitted onto the support column 3. The connecting tube 14 is connected to the dust collection equipment via a pipe. The lower end of the rotating sleeve 18 on the dust collection assembly 4 has an annular connecting groove 19, which is rotatably mounted on the annular connector 17. The protruding locking block 20 is inserted into the limiting grooves 12 on the outer wall of the support column 3. When the height of the dust collection assembly 4 on the support column 3 needs to be adjusted according to the different heights of the concrete blocks to be ground, first hold the rotating sleeve 18 and rotate it around the annular connector 17. During the rotation of the rotating sleeve 18, the protruding locking block 20 fixed on its inner wall will rotate synchronously, causing the protruding locking block 20 to disengage from the limiting grooves 12 on the outer wall of the support column 3. At this time, the dust collection assembly... The fixing of component 4 is released, so that the dust collection component 4 can move longitudinally along the support column 3 through the mounting hole 16 on the connecting sleeve 15. After adjusting the dust collection component 4 to a suitable position higher than the top of the concrete block, the rotating sleeve 18 is rotated in the opposite direction, so that the protruding locking block 20 is re-inserted into the limiting groove 12 of the corresponding height of the support column 3. At this time, the height adjustment and height fixing of the dust collection component 4 are completed, ensuring that the dust collection component 4 is always higher than the top of the concrete block. While the grinding operation is in progress, the connecting tube 14 of the dust collection component 4 is connected to the external dust collection equipment through the pipe. The dust collection equipment is started, and the concrete dust generated by grinding will be concentrated in the area covered by the arc-shaped gathering plate 13 under the blocking and gathering effect of the arc-shaped gathering plate 13. Then, under the negative pressure generated by the dust collection equipment, this concentrated dust enters the pipe through the connecting tube 14 and is finally sucked into the dust collection equipment to achieve the collection of grinding dust.

[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
