Description

Technical Field

[0001] This utility model relates to the technical field of ground leveling devices, specifically a ground flatness fine grinding device. Background Technology

[0002] A floor leveling device is a type of floor construction equipment. Operators typically install a grinding disc at the bottom of the device. The device's own weight creates friction between the horizontally rotating disc and the floor, grinding away surface materials such as terrazzo, concrete, epoxy mortar, and old epoxy flooring to remove and clean the surface structure, thus achieving floor leveling. Operators can also adjust the material and structure of the grinding disc and other abrasive consumables to achieve different effects such as peeling, grinding, and polishing. However, simply changing the grinding disc's material and structure is insufficient for different floor materials. This cannot adjust the pressure between the disc and the floor, leading to situations where a heavier floor leveling device causes excessive damage to softer surfaces, while a lighter device cannot effectively grind harder surfaces, resulting in rework and delays in the construction process. Therefore, the structure of floor leveling devices needs to be improved to enhance operational efficiency. Utility Model Content

[0025] like Figures 1 to 6 The illustrated ground smoothness grinding device includes a base 1 and a pushing assembly 2 connected to the base 1. The base 1 includes a bottom cover assembly 3, a grinding assembly 4 disposed inside the bottom cover assembly 3, a drive assembly 5 connected to the grinding assembly 4, and a first connecting assembly 6 connected to the bottom cover assembly 3. The pushing assembly 2 is provided with a water tank assembly 7 communicating with the inside of the bottom cover assembly 3 and a second connecting assembly 8 cooperating with the first connecting assembly 6. The second connecting assembly 8 surrounds the outside of the drive assembly 5. The second connecting assembly 8 includes a support member 81 connected to the first connecting assembly 6, a support member 82 located on the support member 81, and a counterweight assembly 83 respectively connected to the support member 81 and the support member 82. The counterweight assembly 83 is detachably connected to adjust the grinding pressure between the grinding assembly 4 and the ground.

[0026] This invention, by incorporating a detachable counterweight component, allows operators to flexibly adjust the grinding pressure between the fine grinding component and the ground according to the material and hardness of the surface. This avoids the problems of excessive damage or insufficient grinding caused by the fixed weight of traditional ground leveling devices, which cannot adjust the pressure. As a result, it improves work efficiency and the precision of ground treatment, thereby enhancing the versatility and practicality of the device.

[0027] Specifically, the design of the pushing component facilitates the movement and positioning of the device, improving construction flexibility. The pushing component is equipped with pulleys that contact the ground and handles for operators to grip. Integrating the drive component, grinding component, and counterweight component into the base makes the overall device operate more smoothly when pushed.

[0028] Of course, the grinding components come into contact with the ground, and operators can replace them with diamond grinding discs, resin grinding discs, diamond grinding discs, resin polishing discs, etc., depending on the material of the ground.

[0029] Specifically, the counterweight component is connected to the support and bearing components of the pushing component. It is connected to the first connecting component through the support component. The weight of the counterweight component is transmitted to the fine grinding component inside the bottom cover component through the bottom cover component. The weight of the counterweight component is used to adjust the pressure between the fine grinding component and the ground. The counterweight component adopts a detachable connection method, which allows the operator to easily and quickly adjust the counterweight according to the specific conditions of the ground material during actual construction. The operation is relatively simple. By effectively controlling the degree of grinding, the construction quality can be guaranteed, ground defects caused by unsuitable pressure can be reduced, and the possibility of subsequent rework and repair can be reduced.

[0030] In addition, by setting up a counterweight component, the stability of the base is improved, preventing the base from tipping over during operation, and also reducing the abnormal noise emitted by the bottom cover component during vibration during the grinding process.

[0031] In addition, by setting up a water tank assembly, an appropriate amount of water can be applied to the ground from the direction of the bottom cover assembly to reduce dust diffusion, while also reducing the temperature and wear on the surface of the grinding assembly and extending the service life of the grinding assembly.

[0032] This utility model can perform fine grinding of the flatness of the interior decorative floor of the construction site. The floor flatness fine grinding device grinds the surface of the original concrete floor multiple times, reducing the flatness error of the floor. Compared with making a layer of fine stone concrete leveling layer on the original concrete structure surface, it greatly reduces the risk of common quality defects such as hollowing and cracking.

[0033] like Figures 2 to 6 The ground flatness grinding device shown includes a first connecting component 6 comprising a support portion 61 for supporting the drive component 5 and a first fixing member 62 connected to the support portion 61. The support portion 61 is provided with a first connecting groove 611. The bracket component 81 is provided with a bracket component connecting end 811. The first fixing member 62 is provided with a fixing member connecting end 621 that engages with the first connecting groove 611 and a fixing member positioning end 622 that cooperates with and connects to the bracket component connecting end 811.

[0034] The support portion 61 is provided with a support portion opening 610 through which the connecting shaft of the drive assembly passes.

[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation, the support portion is used to support the drive assembly, enabling the drive assembly to be placed stably and ensuring that the drive assembly can continuously and stably provide power to the fine grinding assembly. This allows the fine grinding assembly to maintain a stable working state during the operation of the ground flatness fine grinding device, avoiding shaking or displacement due to lack of support. The cooperation between the first connecting groove and the connecting end of the support component, the engagement of the fixing member connecting end with the first connecting groove, and the cooperation between the fixing member positioning end and the connecting end of the support component enable a tight connection between the support component and the support portion. The tight engagement and accurate positioning of each component make the entire connection structure more robust, reducing the possibility of loosening or abnormal noise during use due to loose connections, and helping to extend the service life of the device.

[0036] Specifically, the first fastener is detachably connected to the support by a fastener connection end that can be connected to the first connecting groove. Of course, the fastener connection end can be a cylindrical or square structure that matches the shape of the first connecting groove for engagement, or it can be engaged by magnetic connection, snap-fit ​​connection, threaded connection, fastener connection, etc.

[0037] Specifically, the first fastener is detachably connected to the connecting end of the bracket component via the positioning end of the fastener. Of course, the positioning end of the fastener can be an open slot structure that matches the connecting end of the bracket component, and is fastened by fasteners such as screws or bolts.

[0038] Furthermore, the support portion of this invention employs two first fixing members on both sides to secure the bracket component. The bracket component is positioned between the two first fixing members to enhance its stability, and is secured using fasteners such as screws or bolts. Alternatively, it can be secured using magnetic connections, snap-fit ​​connections, threaded connections, or fastener connections.

[0039] like Figures 2 to 6 The invention relates to a ground flatness grinding device. The bottom cover assembly 3 includes a first cover 31, which has a receiving cavity 311 for accommodating the grinding assembly 4, a first opening 312 and a second opening 313 communicating with the receiving cavity 311. The support portion 61 has a first protruding edge 612 extending from the receiving cavity 311 into the first opening 312, an abutting portion 613 connected to the first protruding edge 612 and abutting against the inner side of the first opening 312, and a support portion extension 614 extending from the receiving cavity 311 into the second opening 313. The first connecting groove 611 is located in the support portion extension 614.

[0040] Furthermore, as a preferred embodiment of this utility model and not a limitation, housing the grinding component within the receiving cavity can prevent the grinding component from being interfered with by external factors during device operation. The first protruding edge of the support portion extends from the receiving cavity to the first opening, and the abutting portion abuts against the inner side of the first opening. The extension portion of the support portion extends from the receiving cavity to the second opening, thus forming a tight connection between the support portion and the first cover. The counterweight component transmits pressure to the support portion through the first fixing member, and the tight connection between the support portion and the first cover enhances the overall structural strength, ensuring that the base remains stable even when subjected to vibrations or external forces during the grinding process during device operation.

[0041] Furthermore, the first cover and the support can be fastened together by fasteners such as screws and bolts. Of course, they can also be connected by magnetic attraction, snap-fit ​​connection, threaded connection, fastener connection, etc.

[0042] Specifically, the first protruding edge and the abutment portion enhance the sealing between the bottom cover assembly and the support portion. The sealing structure helps prevent debris and dust generated during the grinding process from entering and transferring to the drive assembly or escaping from the upper side of the first cover, thereby protecting the drive assembly from damage and extending the service life of the device, and also reducing the tendency of dust to drift upwards.

[0043] like Figures 3 to 6 The invention relates to a ground flatness grinding device. The support component 81 has an extension shaft 812 extending outward therefrom. The counterweight assembly 83 includes a fixed counterweight block 831 with one end engaged with the extension shaft 812 and the other end abutting against the support component 82, and a connecting counterweight block 832 connected to the outside of the fixed counterweight block 831. The fixed counterweight block 831 has a first connecting end 8311, and the connecting counterweight block 832 has a second connecting end 8321 that cooperates with the first connecting end 8311. The counterweight assembly 83 also includes a counterweight baffle 833 disposed on the outside of the connecting counterweight block 832.

[0044] Specifically, multiple connecting counterweights are provided. Operators can select the appropriate number and specifications of connecting counterweights according to the different hardness of the ground material during actual construction, and use them in combination with fixed counterweights to flexibly adjust the grinding pressure between the grinding components and the ground. For example, more connecting counterweights can be added when dealing with harder ground materials, while fewer can be added for softer ground materials, thus adapting to different ground surfaces, ensuring grinding effect, and improving the device's ability to cope with various construction scenarios.

[0045] In addition, the matching connection design of the first connecting end and the second connecting end of the counterweight allows for a relatively tight and stable connection between the counterweights. The first connecting end and the second connecting end of the counterweight are connecting holes, which can be fastened by fasteners such as screws and bolts. Of course, they can also be matched by magnetic connection, snap-fit ​​connection, threaded connection, fastener connection, etc.

[0046] Specifically, one end of the fixed counterweight is engaged with the extension shaft, while the other end abuts against the support component. This combination of engagement and abutment ensures that the fixed counterweight is firmly fixed to the support structure, preventing shaking or displacement. Furthermore, the stable connection between the connecting counterweight and the fixed counterweight further strengthens the entire counterweight assembly, ensuring that the pressure generated by the counterweight is consistently applied to the grinding components during operation, thus guaranteeing the reliable implementation of the pressure regulation function.

[0047] Furthermore, the counterweight baffle is located on the outside of the connecting counterweight block, which serves to block and protect it. It can effectively prevent the counterweight block from falling off the support component due to vibration, shaking or other unexpected situations during the operation of the device. The counterweight baffle can be connected to the outside of the connecting counterweight block by fasteners such as screws, or it can be connected to the support component by fasteners such as screws. Of course, it can also be connected and fixed by buckles or other means, so as to facilitate disassembly by operators.

[0048] like Figures 2 to 5 The invention relates to a ground flatness grinding device. The first cover 31 is provided with a water inlet 314 communicating with the water tank assembly 7. A water inlet area 315 is provided between the inner side wall of the first cover 31 and the outer side of the housing 521. The bottom cover assembly 3 includes an inner dustproof ring 32 disposed inside the first cover 31 and an outer baffle ring 33 located outside the first cover 31. The inner dustproof ring 32 is provided with a dustproof ring extension end 321 extending toward the housing 521.

[0049] Furthermore, as a preferred embodiment of this utility model and not a limitation, the water in the water tank can flow into the water inlet area in an orderly and smooth manner through the water inlet. During the ground grinding process, water can be precisely delivered to the vicinity of the grinding components for dust suppression, cooling, lubrication, and other operations, ensuring that the grinding work can be carried out in a water-assisted environment, thereby improving grinding efficiency and quality.

[0050] Additionally, the inner dustproof ring is located inside the first housing, and its extended end, pointing towards the housing, effectively prevents dust, debris, and other impurities generated during the grinding process from spreading upwards. Furthermore, the extended end of the dustproof ring is located between the water inlet area and the ground, allowing water to flow towards the grinding assembly through the extended end, thus preventing water from moving along the inner wall of the first housing while the grinding assembly lacks water lubrication and dust suppression.

[0051] Furthermore, the outer retaining ring is located on the outside of the first cover, which can prevent dust and debris from the external environment from entering the bottom cover assembly. It also reduces the spillage of grinding dust, further improving the dustproof capability of the entire device. Specifically, the outer retaining ring can be made of plastic material. During the movement of the device, the outer retaining ring can push away foreign objects and prevent them from contacting the fine grinding components.

[0052] like Figures 2 to 5 The invention relates to a ground flatness grinding device, wherein the drive assembly 5 includes a motor assembly 51 connected to the upper side of the support 61, a grinding head assembly 52 located in the accommodating cavity 311 and connected to the grinding assembly 4, the grinding head assembly 52 including a housing 521 connected to the first cover 31, a gear assembly located in the housing 521, and a rotating disk 523 meshing with the gear assembly and extending to the outside of the housing 521, and the grinding assembly 4 is connected to the lower side of the rotating disk 523.

[0053] Furthermore, as a preferred embodiment of this utility model and not a limitation, the support provides a stable mounting base for the motor assembly, ensuring the motor remains stable during operation and preventing shaking or displacement due to unstable installation from affecting power output. As a power source, the motor can stably provide sufficient power to the grinding head assembly and the fine grinding assembly, ensuring that grinding work can be carried out continuously and efficiently.

[0054] Specifically, the gear assembly in the grinding head assembly is located inside the housing. By meshing with the rotating disk that extends to the outside of the housing, it achieves an effective power transmission path from the motor to the fine grinding assembly. The gear assembly can precisely distribute and transmit the rotational power of the motor, driving the rotating disk to rotate stably, and thus driving the connected fine grinding assembly to perform grinding operations.

[0055] Specifically, the first cover and the housing can be fastened by fasteners such as screws and bolts. Of course, the fasteners can also be connected to the housing in sequence through the first cover and the support, so that the support will be forced to move the first cover and the housing downward, thereby giving the grinding assembly connected to the rotating disk downward pressure.

[0056] like Figures 2 to 6 The above describes a ground flatness grinding device. The first cover 31 is provided with a third opening 316 communicating with the housing 521. The bottom of the housing 521 is provided with a housing drain port 5211. Both the third opening 316 and the housing drain port 5211 are provided with sealing parts 317.

[0057] Furthermore, as a preferred embodiment of this utility model and not a limitation, the housing contains engine oil to cool and lubricate the rotating shafts of the gear assembly and motor assembly, preventing overheating or insufficient lubrication from causing malfunctions in the rotating disc. Because the gear assembly has high output power and significant wear, the engine oil needs to be changed regularly to prevent metal powder mixed in the oil from affecting operation. When the engine oil in the housing needs changing, the operator opens the sealing part of the drain port of the housing to allow the engine oil to drain smoothly. After sealing the drain port, the operator opens the sealing part located at the third opening and pours in additional engine oil through the third opening. Finally, the sealing part is closed to ensure a proper seal within the housing.

[0058] Optionally, in some embodiments, the sealing part can seal the third opening and the housing drain port by means of threaded parts, bolts, resin seals, etc.

[0059] like Figures 2 to 5 The invention relates to a ground flatness grinding device, wherein a protective cover 511 is connected to the outside of the motor assembly 51, the protective cover 511 has a protective cover opening 512, a heat dissipation drive component 513 located inside the protective cover 511, and a dustproof plate 514 covering the protective cover opening 512, the dustproof plate 514 having a dustproof plate opening 5141 communicating with the inside of the protective cover 511.

[0060] Furthermore, as a preferred embodiment of this utility model and not a limitation, the protective cover serves to protect the heat dissipation drive component. The heat dissipation drive component is installed inside the protective cover. When the motor assembly generates heat during operation, the heat dissipation drive component actively promotes airflow within the protective cover, accelerating heat dissipation. For example, a fan or other heat dissipation drive component can promptly expel hot air and introduce cool outside air, thereby effectively reducing the temperature of the motor assembly. This prevents problems such as overheating shutdown due to prolonged high-temperature operation and accelerated aging of components, ensuring that the motor always operates within a suitable temperature range and stably and continuously provides power to the grinding device. Alternatively, a semiconductor cooling device can be used to cool the electrode assembly.

[0061] Specifically, the dustproof plate has a dustproof plate opening, which not only ensures that the heat dissipation drive components can function normally and allows air to circulate inside and outside the protective cover, but also intercepts and filters dust through the dustproof plate, preventing a large amount of external dust from entering the protective cover with the airflow and affecting the motor components. This achieves an organic combination of heat dissipation and dust prevention, so that the motor components can effectively dissipate heat and be protected from dust interference, maintaining a good operating condition.

[0062] Optionally, in some embodiments, the heat dissipation drive is a fan and is connected to the connecting shaft of the motor assembly, and the fan rotates together when the motor assembly is running.

[0063] When it gets hot, the fan can also be set up separately to keep the motor assembly cool.

[0064] like Figures 2 to 5 The invention relates to a ground flatness grinding device, wherein the support component 81 includes a left support 813 and a right support 814 respectively connected to both sides of the bottom cover assembly 3, the counterweight assembly 83 is provided in two sets and is respectively connected to the left support 813 and the right support 814, the front cover assembly 815 is connected between the left support 813 and the right support 814, and the motor assembly 51 is located in the space formed by the left support 813, the right support 814 and the front cover assembly 815.

[0065] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the present invention is provided with two water inlets. The left bracket is provided with a left bracket through hole through which the water supply pipe passes, and the right bracket 814 is provided with a right bracket through hole 8140 through which the water supply pipe passes. The water pipes are connected between the water tank assembly and the water inlets through the left bracket through hole and the right bracket through hole, respectively. The left bracket through hole and the right bracket through hole are respectively higher than the height of the water inlet or are respectively level with the height of the water inlet, so as to make the water intake smoother.

[0066] Specifically, the counterweight assembly consists of two sets, connected to the left and right supports respectively. This symmetrical design ensures that the entire floor grinding device experiences more even and balanced forces in the front-to-back and left-to-right directions. During the grinding process, when the device is running or moving, the dual counterweights effectively prevent tilting, swaying, or other instability caused by uneven weight distribution on one side. This ensures the device is placed stably on the ground, maintaining good and stable contact between the grinding components and the ground, thereby improving the precision and quality of the grinding process and ensuring its smooth operation.

[0067] Furthermore, the front cover assembly connects between the left and right supports, and the space they enclose provides further protection for the motor assembly, preventing physical damage from accidental collisions. The left and right supports, along with the space they form with the front cover assembly, provide a relatively enclosed and stable mounting position for the motor assembly, preventing displacement and swaying during operation due to a lack of stable support. Moreover, shock-absorbing components can be installed within the enclosed space to abut against the motor assembly, thereby reducing noise generated by motor vibration while securing the motor assembly.

[0068] like Figures 2 to 5The invention relates to a ground flatness grinding device. The front cover assembly 815 includes a front crossbeam 8151 connected to the left side bracket 813 and the right side bracket 814 respectively, a front cover 8152 connected to the outside of the front crossbeam 8151, and a shock absorber located between the front cover 8152 and the front crossbeam 8151. The front cover 8152 includes a left connecting portion 81521 connected to the left side bracket 813, a right connecting portion 81522 connected to the right side bracket 814, and a front connecting portion 81523 connected between the left connecting portion 81521 and the right connecting portion 81522. The front cover 8152 is U-shaped, and the front crossbeam 8151 is U-shaped. The front cover 8152 and the front crossbeam 8151 enclose a shock-absorbing space 8153 for accommodating the shock absorber.

[0069] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the front cover, as an external protective structure, can shield and protect key components such as motor assemblies inside the device, preventing collisions with hard objects, intrusion of dust and debris, etc., reducing the risk of damage to internal components from external factors, maintaining internal components in a relatively clean and safe environment, helping to ensure the stable performance of each component and ensuring the normal operation of the device.

[0070] In addition, the front crossbeam is connected to the left and right supports respectively, which can provide a stable support frame for the front cover, so that the front cover can be firmly installed on the device. The front cover is connected to the corresponding left and right supports through the left and right connecting parts, which not only maintains the structural strength, but also improves the assembly efficiency and reduces the installation time cost.

[0071] Furthermore, the shock absorbers effectively buffer the vibrations generated during the operation of the device, protecting internal components and reducing the transmission of vibrations to the outside of the device. This prevents the entire device from generating excessive noise due to vibration, making the operation more stable and quiet, and improving the user experience for operators. Specifically, the shock absorbers are installed within the damping space formed by the U-shaped front crossbeam and the U-shaped front cover. By buffering vibrations, they can prevent problems such as loosening of connections between components and accelerated wear of parts caused by long-term vibration, extending the service life of components and ensuring stable operation of the device.

[0072] Example 1

[0073] like Figures 1 to 6The illustrated ground smoothness grinding device includes a base 1 and a pushing assembly 2 connected to the base 1. The base 1 includes a bottom cover assembly 3, a grinding assembly 4 disposed inside the bottom cover assembly 3, a drive assembly 5 connected to the grinding assembly 4, and a first connecting assembly 6 connected to the bottom cover assembly 3.
