Description

Technical Field

[0001] This utility model belongs to the field of building construction equipment technology, specifically a laser flooring construction integrated equipment with a vibration compensation structure. Background Technology

[0002] A laser-guided floor paver is a piece of equipment used for floor construction, primarily employing a laser-based measurement and control system to achieve high-precision floor paving operations. When the paver is running, its leveling device spreads and compacts the ground material, creating a floor surface that meets design requirements. Simultaneously, a high-precision measuring robot monitors the floor's flatness and elevation data in real time, feeding this information back to the control system to adjust paving parameters, thereby improving construction quality.

[0003] However, in actual construction, the vibration generated by equipment operation may affect measurement accuracy and smoothness. Vibration can cause deviations in the data acquired by the measuring robot, and it can also lead to instability in the working state of the paving device, resulting in uneven paving. This vibration interference is particularly significant during long-term or large-area construction and is difficult to completely avoid. To address these issues, existing technologies have not yet proposed an effective solution to completely eliminate the impact of vibration on measurement and paving.

[0004] Regarding the aforementioned technologies, the inventors believe that the combined use of laser floor pavers and measuring robots is limited by vibration interference. Therefore, they have proposed an integrated laser floor construction device with a vibration compensation structure to solve the above problems. Utility Model Content

[0005] To address the issue of decreased measurement accuracy and flatness due to vibration interference when laser floor pavers are used in conjunction with high-precision measuring robots, this invention provides an integrated laser floor construction device with a vibration compensation structure.

[0006] The integrated laser flooring construction equipment with a vibration compensation structure provided by this utility model adopts the following technical solution:

[0007] An integrated laser flooring construction device with vibration compensation structure includes a support frame. Four vibration-damping legs are symmetrically installed at the bottom of the support frame, each leg being bolted to one of the four corners of the bottom of the support frame. A paving assembly is fixedly installed in the middle of the support frame. The paving assembly includes a paving plate and a compaction wheel. The paving plate is fixed to the center of the bottom of the support frame via threaded connectors. The compaction wheel is mounted on the rear end of the paving plate via a rotating shaft and is connected to a drive motor. A measurement module is installed at the top of the support frame. The measurement module includes a laser rangefinder and a data processing unit. The laser rangefinder is fixed to the center of the top of the support frame via a bracket. The data processing unit is mounted on the rear side of the laser rangefinder via screws and connected to the laser rangefinder via a signal line. A vibration compensation mechanism is also provided inside the support frame.

[0008] Preferably, the vibration compensation mechanism includes a limiting guide rail, a sliding block, and a compensation algorithm module. The limiting guide rail is fixed to the inner wall of the support frame by welding. The sliding block is mounted on the limiting guide rail by ball bearings and slides with it. The top of the sliding block is fixed to the bottom of the measurement module by bolts. The compensation algorithm module is mounted inside the data processing unit by screws and is electrically connected to the data processing unit.

[0009] Preferably, the shock-absorbing outrigger includes an outer cylinder, an inner rod, and an elastic element. The outer cylinder is fixed to the bottom of the support frame by bolts. The inner rod is inserted into the outer cylinder and slides with the outer cylinder through a guide groove. The elastic element is sleeved on the outside of the inner rod and located inside the outer cylinder. The two ends of the elastic element are in contact with the bottom of the outer cylinder and the top of the inner rod, respectively.

[0010] Preferably, there are two limiting guide rails, which are symmetrically arranged on both sides of the inner wall of the support frame. The two ends of the sliding block are respectively embedded in the two limiting guide rails and slide in cooperation with the limiting guide rails.

[0011] Preferably, the compensation algorithm module includes a vibration detection unit and a data correction unit. The vibration detection unit is installed inside the data processing unit by screws and is electrically connected to the data processing unit. The data correction unit is connected to the vibration detection unit by a signal line and receives its output signal.

[0012] Preferably, the front end of the paving slab is provided with a scraper, which is fixed to the front end of the paving slab by bolts and is arranged at a certain angle to the paving slab. The bottom of the scraper is provided with a wear-resistant layer, which is fixed to the bottom of the scraper by adhesive bonding.

[0013] Preferably, the surface of the compaction wheel is provided with anti-slip texture, the anti-slip texture is evenly distributed along the circumference of the compaction wheel, and the compaction wheel is connected to the rotating shaft through a bearing and can rotate freely around the rotating shaft.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] By incorporating a vibration compensation mechanism within the support frame, the movement range of the measurement module is limited through the cooperation of limiting guide rails and sliding blocks. Simultaneously, the vibration detection unit within the compensation algorithm module collects vibration data in real time, and the data correction unit corrects the measurement data, effectively reducing the impact of vibration on measurement accuracy. The shock-absorbing legs absorb external vibration energy through elastic elements, further reducing the amplitude of vibration transmitted to the support frame. The scraper at the front of the paving slab ensures even distribution of the ground material, while the anti-slip texture on the compaction wheel surface enhances the stability of the compaction process, preventing uneven paving caused by vibration. Compared to existing technologies, this solution effectively suppresses the impact of vibration through a combination of hardware structure and software algorithms. This significantly improves the measurement accuracy and flatness of the integrated laser flooring construction equipment during long-term or large-area construction, solves the measurement deviation and uneven paving problems caused by vibration interference, and enhances overall construction efficiency and quality.

[0016] In this invention, the connection and positional relationships between the various components are clearly defined, ensuring the overall stability and functionality of the equipment. For example, the shock-absorbing legs are fixed to the bottom of the support frame with bolts, ensuring their secure installation; the limiting guide rail is fixed to the inner wall of the support frame by welding, ensuring its stability under vibration; the sliding block is mounted on the limiting guide rail using ball bearings, achieving both sliding function and reducing frictional resistance. These specific connection methods and positional arrangements make the technical solution of this invention highly feasible and practical, effectively solving the vibration interference problem mentioned in the background art.

[0023] This utility model provides an integrated laser flooring construction device with a vibration compensation structure, and its specific implementation method is described in detail with reference to the accompanying drawings. Figure 1 This is a schematic diagram of the overall structure of this utility model, showing the arrangement of the support frame 1, shock-absorbing legs 2, paving components, measurement module and vibration compensation mechanism. Figure 2 This is a partial enlarged view of the vibration compensation mechanism, showing the connection method of the limit guide rail 7, the sliding block 8, and the measurement module. Figure 3 This is a cross-sectional view of the shock-absorbing outrigger 2, showing the structure and assembly relationship of the outer cylinder 10, inner rod 11, and elastic element 12. Figure 4 This is a side view of the paving components, highlighting the structure and positional relationship of the paving slab 3, scraper 13, and compaction roller 4.

[0024] The support frame 1, serving as the foundation structure of the entire equipment, adopts a rectangular steel frame design. Four shock-absorbing legs 2 are bolted to the four corners of its bottom. Each shock-absorbing leg 2 consists of an outer cylinder 10, an inner rod 11, and an elastic element 12. The outer cylinder 10 is bolted to the bottom of the support frame 1. The inner rod 11 is inserted into the outer cylinder 10 and slides within it via a guide groove. The elastic element 12 is sleeved outside the inner rod 11 and located inside the outer cylinder 10, with its two ends contacting the bottom of the outer cylinder 10 and the top of the inner rod 11, respectively. This design allows the shock-absorbing legs 2 to absorb external vibration energy and, through the compression and rebound of the elastic element 12, reduce the amplitude of vibration transmitted to the support frame 1.

[0025] A paving assembly, including a paving plate 3 and a compaction roller 4, is fixedly installed in the middle of the support frame 1. The paving plate 3 is fixed to the center of the bottom of the support frame 1 by threaded connectors. A scraper 13 is provided at the front end, which is bolted to the front end of the paving plate 3 and arranged at a certain angle. A wear-resistant layer is provided at the bottom, which is fixed to the bottom of the scraper 13 by adhesive bonding. The compaction roller 4 is installed at the rear end of the paving plate 3 via a rotating shaft and is connected to a drive motor. Anti-slip textures 14 are provided on the surface of the compaction roller 4, evenly distributed around its circumference. The compaction roller 4 is connected to the rotating shaft via bearings and can rotate freely around the shaft. The paving plate 3 is used to evenly distribute the ground material, the scraper 13 achieves initial leveling of the ground material through its inclined angle design, and the compaction roller 4 further ensures the flatness of the ground through rolling compaction.

[0026] A measurement module is installed at the top of the support frame 1. The measurement module includes a laser rangefinder 5 and a data processing unit 6. The laser rangefinder 5 is fixed to the center of the top of the support frame 1 by a bracket. The data processing unit 6 is installed on the rear side of the laser rangefinder 5 by screws and connected to the laser rangefinder 5 via a signal line. The measurement module is used to collect ground height data in real time and transmit the data to the data processing unit 6 for analysis and processing. A vibration compensation mechanism is also installed inside the support frame 1. The vibration compensation mechanism includes limit rails 7, sliding blocks 8, and a compensation algorithm module 9. There are two limit rails 7, symmetrically arranged on both sides of the inner wall of the support frame 1, and fixed to the inner wall of the support frame 1 by welding. The sliding blocks 8 are mounted on the limit rails 7 by ball bearings and slide with them. The two ends of the sliding blocks 8 are respectively embedded in the two limit rails 7 and slide with them. The top of the sliding blocks 8 is fixed to the bottom of the measurement module by bolts. The compensation algorithm module 9 is installed inside the data processing unit 6 by screws and is electrically connected to the data processing unit 6. The compensation algorithm module 9 includes a vibration detection unit and a data correction unit. The vibration detection unit is installed inside the data processing unit 6 by screws and is electrically connected to the data processing unit 6. The data correction unit is connected to the vibration detection unit through a signal line and receives its output signal.

[0027] In actual operation, when the equipment starts working, the shock-absorbing legs 2 first absorb external vibrations. The outer cylinder 10 and the inner rod 11 slide relative to each other through the cooperation of the guide grooves. The elastic element 12 deforms under the action of vibration, thereby absorbing vibration energy. The paving plate 3 and the scraper 13 work together to evenly distribute and initially level the ground material. Then, the compaction wheel 4 rolls and compacts the ground material under the drive of the drive motor to ensure the flatness of the ground. The laser rangefinder 5 in the measurement module collects ground height data in real time and transmits the data to the data processing unit 6, which performs preliminary processing on the received data. At the same time, the sliding block 8 in the vibration compensation mechanism slides on the limit guide rail 7 to limit the movement range of the measurement module and reduce the impact of vibration on its position. The vibration detection unit in the compensation algorithm module 9 collects vibration data in real time and corrects the measurement data through the data correction unit, thereby reducing the impact of vibration on the measurement accuracy.

[0028] The entire operation of the equipment relies on the close cooperation between its various components. The shock-absorbing legs 2 absorb vibration energy through the elastic element 12, reducing the impact of vibration on the support frame 1. The cooperation between the limiting guide rail 7 and the sliding block 8 restricts the movement range of the measurement module, while the compensation algorithm module 9 effectively ensures measurement accuracy through real-time acquisition and correction of vibration data. The design of the paving slab 3 and the compaction wheel 4 ensures uniform distribution and smooth compaction of the ground material, and the detailed design of the scraper 13 and the anti-slip texture 14 further improves the construction quality. Through the above structure and operation mode, this invention effectively solves the problem of decreased measurement accuracy and smoothness caused by vibration interference during laser flooring construction, meeting actual construction needs.

[0029] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0030] In actual construction, the support frame 1 is first fixed to the ground using shock-absorbing legs 2 to ensure the initial stability of the equipment. The outer cylinder 10 of the shock-absorbing legs 2 is connected to the bottom of the support frame 1 by bolts. The inner rod 11 is inserted into the outer cylinder 10 and slides through a guide groove. The elastic element 12 is sleeved outside the inner rod 11 and located inside the outer cylinder 10, with its two ends contacting the bottom of the outer cylinder 10 and the top of the inner rod 11, respectively. When the equipment is running, ground vibration energy is transmitted to the elastic element 12 through the inner rod 11. The elastic element 12 deforms to absorb the vibration energy and reduces the amplitude of vibration transmitted to the support frame 1 through rebound. This design effectively reduces the impact of external vibration on the overall stability of the equipment, providing a good foundation for subsequent measurement and paving operations.

[0031] Subsequently, the paving assembly is activated to spread the ground material. The paving slab 3 is fixed to the center of the bottom of the support frame 1 via threaded connectors. A scraper 13 is located at its front end, secured with bolts and angled towards the paving slab 3. The wear-resistant layer on the bottom of the scraper 13 resists material friction, extending its service life. After the ground material is evenly distributed by the paving slab 3, the scraper 13, with its angled design, performs initial leveling. Next, the compaction roller 4, driven by a motor, rotates freely around its axis. Its surface features uniformly distributed anti-slip texture 14, further enhancing the stability of the compaction process and ensuring the ground material is evenly compacted. This series of operations achieves efficient paving and leveling of the ground material.

[0032] Meanwhile, the measurement module begins operation. The laser rangefinder 5 is fixed to the top center of the support frame 1 via a bracket, collecting ground height data in real time and transmitting the data to the data processing unit 6 for preliminary analysis. However, due to inevitable vibrations during equipment operation, the position of the measurement module may be affected. Therefore, the limiting guide rails 7 and sliding blocks 8 in the vibration compensation mechanism play a crucial role. The limiting guide rails 7 are fixed to both sides of the inner wall of the support frame 1 by welding, and the sliding blocks 8 are mounted on the limiting guide rails 7 via ball bearings and slide against them. The two ends of the sliding blocks 8 are embedded inside the two limiting guide rails 7, and the top is fixed to the bottom of the measurement module by bolts. When vibration causes a slight displacement of the measurement module, the sliding blocks 8 slide on the limiting guide rails 7, limiting the range of motion of the measurement module and thus reducing the impact of vibration on its positional accuracy.

[0033] To further improve measurement accuracy, the vibration detection unit in compensation algorithm module 9 collects vibration data in real time and transmits the data to the data correction unit via a signal line. The data correction unit corrects the height data collected by the laser rangefinder 5 based on the data provided by the vibration detection unit, thereby eliminating the interference of vibration on the measurement results. For example, when vibration causes a slight shift in the measurement module, the data correction unit calculates the shift based on the feedback from the vibration detection unit and compensates for the original measurement data, ensuring that the final output data has high accuracy.

[0034] Through the above steps, the entire equipment achieves an efficient and stable construction process. The shock-absorbing legs 2 absorb external vibration energy through the elastic element 12, reducing the impact of vibration on the support frame 1; the cooperation of the limiting guide rail 7 and the sliding block 8 restricts the movement range of the measuring module, ensuring its positional accuracy; the compensation algorithm module 9 further improves the reliability of the measuring module through real-time acquisition and correction of vibration data. The paving slab 3 and the compaction wheel 4 work together to ensure the uniform distribution and smooth compaction of the ground material, while the design of the scraper 13 and the anti-slip texture 14 further optimizes the construction quality. Ultimately, this invention effectively solves the problem of decreased measurement accuracy and smoothness caused by vibration interference during laser flooring construction, meeting actual construction needs.
