Abstract
Description
Technical Field
[0001] This application relates to the construction of building foundation surfaces, specifically a grinding device for the construction of diamond abrasion resistant flooring. Background Technology
[0002] Emery abrasion-resistant hardened flooring, commonly known as emery abrasion-resistant flooring, has rapidly gained popularity in Europe and America since its introduction in the 1970s, becoming a perfect replacement for terrazzo flooring. By the late 1980s, abrasion-resistant flooring had become the preferred choice in developed countries. Existing devices mostly use a unidirectional continuous rotation grinding structure. When facing rough surfaces or corner areas, uneven force can easily lead to local over-grinding or omissions. This is especially true in fine construction scenarios, where deviations often occur. Traditional devices require manual mechanical adjustment of the grinding height, making it difficult to adapt to ground undulations (such as cement protrusions or differences in the height of tile joints) in real time. This can result in gaps or excessive pressure between the grinding head and the ground, affecting the effect or even damaging the equipment. Utility Model Content
[0003] In view of the above-mentioned related technologies, the purpose of this application is to provide a grinding device for the construction of diamond abrasion wear-resistant flooring, which solves the problems of uneven grinding caused by the unidirectional rotation of traditional floor grinding devices, and the difficulty in adapting to the unevenness and poor fit of the ground by manually adjusting the height. It realizes bidirectional grinding and automatic height adjustment, thereby improving the effect.
[0004] This application provides a grinding device for diamond abrasion-resistant floor construction, employing the following technical solution: It includes a main body, with a mounting frame fixedly connected to the top edge of the main body. A first motor is fixedly connected to the lower top surface of the mounting frame. A first rotating rod is fixedly connected to the output shaft of the first motor. A first half-gear disk is fixedly connected to the bottom end of the first rotating rod. An annular gear ring is fixedly connected to the top of the first half-gear disk using a fixing plate. The inner wall of the annular gear ring has semi-circular teeth, and the teeth of the annular gear ring and the first half-gear disk are positioned in opposite directions. The middle part of the main body is slidably connected via a T-shaped slider. The main body is equipped with a column, and a long toothed column is fixedly connected to the top center of the column. The long toothed column is positioned between the first half gear disk and the ring gear ring, and can mesh with the first half gear disk and the ring gear ring respectively. A groove shell is fixedly connected to the middle of one side of the column. The inner wall of the groove shell has toothed grooves on both sides. A second motor is fixedly connected to the top of the main body by means of a fixing plate. A second rotating rod is fixedly connected to the output shaft of the second motor. A second half gear disk is fixedly connected to one end of the second rotating rod. The second half gear disk is placed in the groove shell and meshes with the groove shell. By adopting the above technical solution, and through the arrangement of a first motor, a first half-gear disk, an annular gear ring, a column, and a second motor, a second half-gear disk, and a slotted shell, the first motor is turned on. When the first motor runs, it drives the first rotating rod to rotate, thus causing the annular gear ring to rotate synchronously during the rotation of the first half-gear disk. Since the tooth directions of the annular gear ring and the first half-gear disk are opposite, and the elongated toothed column is located between them and can mesh separately, the annular gear ring and the elongated toothed column will alternately mesh and transmit power during the rotation of the annular gear ring and the first half-gear disk. Subsequently, the bottom surface of the assembled chassis is ground to make the second half-gear... When the wheel rotates, the second half-gear meshes with the teeth on the inner wall of the groove shell, causing the groove shell to move up and down. As the height of the groove shell changes, the height of the column also changes accordingly. This allows the assembly chassis to adapt to the height undulations of the construction surface, ensuring that the assembly chassis remains in contact with the construction surface throughout the grinding process. This enables the second motor to be activated, allowing the groove shell and the second half-gear to mesh and adjust the height of the grinding device. This allows the device to adapt to the unevenness of different construction surfaces and to grind surfaces of different heights at different construction locations, thereby improving the overall grinding effect.
[0005] Preferably, an assembly base is fixedly connected to the end of the column away from the elongated toothed column, the assembly base is fixedly connected to the elongated toothed column by a rod, and the rod is rotatably connected to the column, and a water collection shell is connected to the top of the assembly base.
[0006] By adopting the above technical solution, water is collected, which facilitates subsequent wetting of the bottom surface and brush ring.
[0007] Preferably, a brush ring is fixedly connected to the lower surface of the assembly chassis, and the brush ring is connected to the water collection shell.
[0008] By adopting the above technical solution, the bottom surface is moistened during the grinding process, which enhances the friction during grinding and thus improves the grinding effect.
[0009] Preferably, a plurality of grinding wheels arranged in a circular array are fixedly connected to the lower surface of the assembly chassis, and grinding discs are fixed to the bottom of each of the grinding wheels.
[0010] By adopting the above technical solutions, the polishing effect is improved, and the polishing is made more refined.
[0011] Preferably, two wheel axles are fixedly connected to one side of the main body, and a common rear scraper is fixedly connected to one side of the two wheel axles.
[0012] By adopting the above technical solution, residual dirt or slurry can be scraped off after the device passes through, making the construction surface cleaner and tidier.
[0013] Preferably, a power module is fixedly connected to the top of the main body, the power module is electrically connected to two wheel axles, and two water storage tanks are fixedly connected to the top edge of the main body.
[0014] By adopting the above technical solution, the water pump can be started during use, so that the water pump draws the water storage tank into the water collection shell through the water pipe, and then the water collection shell moistens the brush ring with water.
[0015] Preferably, the lower surface of the inner wall of the two water storage tanks is inclined downward at a 45-degree angle, and the bottom of both water storage tanks is connected to a water pipe.
[0016] By adopting the above technical solutions, water flow is made smoother, avoiding waste caused by water not flowing out completely.
[0017] Preferably, the two water pipes extend through to the bottom of the main body and correspond to the water collection shell, and two water pumps are fixedly connected to the top of the main body, both of which are connected to the water pipes.
[0018] By adopting the above technical solution, water is extracted and transported, which then enables the bottom surface to be moistened when the grinding wheel and brush ring grind and sweep the bottom surface.
[0019] In summary, this application includes at least one of the following beneficial technical effects: This grinding equipment for constructing abrasive-resistant flooring utilizes a first motor, a first half-gear disc, an annular gear ring, and a column, as well as a second motor, a second half-gear disc, and a casing. When the first motor is activated, it drives a first rotating rod, causing the annular gear ring to rotate synchronously with the first half-gear disc. Since the teeth of the annular gear ring and the first half-gear disc are in opposite directions, and a long toothed column is located between them and can mesh independently, the annular gear ring alternately meshes with the long toothed column during the rotation of the first half-gear disc. The base plate is then assembled to grind the bottom surface. When the second half-gear rotates, it meshes with the teeth on the inner wall of the slotted shell, causing the slotted shell to move up and down. As the height of the slotted shell changes, the height of the column also changes accordingly. This allows the assembly chassis to adapt to the height undulations of the construction surface, ensuring that the assembly chassis remains in contact with the construction surface throughout the grinding process. This enables the second motor to be activated, allowing the slotted shell and the second half-gear to mesh and adjust the height of the grinding device. This allows the device to adapt to the varying heights of different construction surfaces and to grind surfaces at different construction locations, thereby improving the overall grinding effect.
[0020] This grinding equipment for diamond abrasion wear-resistant floor construction comprises a rear scraper, a water tank, water pipes, a water pump, a water collection shell, a grinding wheel, and a brush ring. During operation, the water pump draws water from the tank into the water collection shell, which then overflows, wetting the brush ring. As the grinding wheel and brush ring rotate and rub against the surface, the brush ring's movement keeps the surface moist, preventing dust generation. Simultaneously, the rear scraper removes any remaining slurry, achieving the goal of preventing dust generation during grinding and removing residual dirt or slurry after the equipment has passed, resulting in a cleaner and more tidy surface.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0024] Example 1: A grinding device for constructing abrasive-resistant flooring, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a main body 1, a mounting bracket 8 fixedly connected to the top edge of the main body 1, a first motor 9 fixedly connected to the lower top surface of the mounting bracket 8, a first rotating rod 10 fixedly connected to the output shaft of the first motor 9, a first half-gear disk 11 fixedly connected to the bottom end of the first rotating rod 10, an annular gear ring 12 fixedly connected to the top of the first half-gear disk 11 by a fixing plate, the inner wall of the annular gear ring 12 having half-circle teeth, and the teeth of the annular gear ring 12 and the first half-gear disk 11 being positioned in opposite directions, a column 13 slidably connected to the middle of the main body 1 via a T-shaped slider, and a long toothed column 14 fixedly connected to the top middle of the column 13. 4 is positioned between the first half-gear disk 11 and the annular gear ring 12, and the elongated toothed column 14 can mesh with the first half-gear disk 11 and the annular gear ring 12 respectively. A groove shell 22 is fixedly connected to the middle of one side of the column 13. The inner wall of the groove shell 22 has toothed grooves on both sides. The top of the main body 1 is fixedly connected to the second motor 19 by means of a fixing plate. The output shaft of the second motor 19 is fixedly connected to the second rotating rod 20. One end of the second rotating rod 20 is fixedly connected to the second half-gear disk 21. The second half-gear disk 21 is placed in the groove shell 22 and meshes with the groove shell 22. Through the first motor 9, the first half-gear disk 11, and the first half-gear disk 12, the column 13 is connected to the groove shell 22. The arrangement of the annular gear ring 12, column 13, second motor 19, second half-gear disk 21, and slotted housing 22 enables the first motor 9 to be turned on. When the first motor 9 is running, it drives the first rotating rod 10 to rotate, causing the annular gear ring 12 to rotate synchronously during the rotation of the first half-gear disk 11. Since the tooth directions of the annular gear ring 12 and the first half-gear disk 11 are opposite, and the elongated toothed column 14 is located between them and can mesh separately, the annular gear ring 12 will alternately mesh with the elongated toothed column 14 during the rotation of the annular gear ring 12 and the first half-gear disk 11. Subsequently, the mounting chassis 15 is assembled, and the bottom surface is polished to allow the second half-gear disk 21 to... During rotation, the second half-gear disk 21 meshes with the inner wall teeth of the groove shell 22, causing the groove shell 22 to move up and down. As the height of the groove shell 22 changes, the height of the column 13 also changes accordingly. This allows the assembly chassis 15 to adapt to the height undulations of the construction surface, ensuring that the assembly chassis 15 remains in contact with the construction surface during grinding. This enables the second motor 19 to be activated, allowing the groove shell 22 and the second half-gear disk 21 to mesh, thereby adjusting the height of the grinding device. This allows the device to adapt to the varying heights of different construction surfaces during grinding, and to grind surfaces of different heights at different construction locations, thus improving the overall grinding effect.
[0025] Example 2: A grinding device for constructing abrasive-resistant flooring, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes a column 13 with an assembly base 15 fixedly connected to one end away from the long toothed column 14. The assembly base 15 and the long toothed column 14 are fixedly connected by a rod, which is rotatably connected to the column 13. A water collection shell 16 is connected to the top of the assembly base 15. A brush ring 18 is fixedly connected to the lower surface of the assembly base 15 and is connected to the water collection shell 16. Multiple grinding discs 17 arranged in a ring array are fixedly connected to the lower surface of the assembly base 15. Grinding discs are fixedly attached to the bottom of each grinding disc 17. Two wheel axles 2 are fixedly connected to one side of the main body 1. A common rear scraper 3 is fixedly connected to one side of the two wheel axles 2. A power module 4 is fixedly connected to the top of the main body 1 and is electrically connected to the two wheel axles 2. Two water storage tanks 5 are fixedly connected to the top edge of the main body 1. The lower surface of the inner wall of the two water storage tanks 5 is inclined downward at a 45-degree angle. Water pipes 7 are connected to the bottom of the two water storage tanks 5. 7 extends through to the bottom of the main body 1 and corresponds to the water collection shell 16. Two water pumps 6 are fixedly connected to the top of the main body 1, both pumps 6 being connected to the water pipe 7. Through the arrangement of the rear scraper 3, water tank 5, water pipe 7, water pumps 6, water collection shell 16, grinding wheel 17, and brush ring 18, the water pumps 6 can be started during use. When the water pumps 6 are running, they generate suction through the water pipe 7, drawing water from the water tank 5 into the water collection shell 16. Subsequently, the water in the water collection shell 16 flows... When the water overflows, it moistens the brush ring 18. After the brush ring 18 is wetted, when the grinding wheel 17 and the brush ring 18 rotate and rub against the construction surface, the brush ring 18 wets the surface during the sweeping process to prevent dust from being generated during the friction. At the same time, after the device passes, the scraper 3 scrapes off the residual slurry on the surface. This achieves the purpose of preventing dust from being generated on the surface during grinding and removing residual dirt or slurry after the device passes, making the construction surface cleaner and tidier.
[0026] The implementation principle of this application embodiment is as follows: First, sufficient water is added to the water storage tank 5. Then, the power module 4 and the first motor 9 are turned on. When the first motor 9 runs, it drives the first rotating rod 10 to rotate, so that during the rotation of the first half gear disk 11, the annular gear ring 12 also rotates synchronously. Since the tooth directions of the annular gear ring 12 and the first half gear disk 11 are opposite, and the long tooth column 14 is located between them and can mesh separately, the annular gear ring 12 will alternately mesh with the long tooth column 14 during the rotation of the first half gear disk 11. Then, the chassis 15 is assembled and the bottom surface is polished. The entire device moves by running through the wheel axle 2. At this time, the second motor is turned on according to the different construction locations. 19. When the second half gear disk 21 rotates, it meshes with the inner wall teeth of the groove shell 22 during rotation, causing the groove shell 22 to move up and down. As the height of the groove shell 22 changes, the height of the column 13 also changes, so that the assembly chassis 15 can adapt to the height fluctuations of the construction bottom surface. This ensures that the assembly chassis 15 can always fit the construction bottom surface during the grinding process. When there is a lot of dust at the construction bottom, the worker starts the water pump 6, which pumps the water storage tank 5 into the water collection shell 16 through the water pipe 7. Then, the water collection shell 16 moistens the brush ring 18 with water. When the grinding wheel 17 and the brush ring 18 grind and sweep the bottom surface, the bottom surface is moistened, reducing dust. At the same time, after the device passes, the scraper 3 scrapes off the remaining slurry.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
