Description

Technical Field

[0001] This application relates to the field of building construction technology, and specifically to an integrated multi-functional wall treatment device. Background Technology

[0002] In construction, wall sanding, putty application, and paint spraying are core processes that determine the quality of the wall surface. Currently, the industry mainly adopts a "manual-assisted single-function equipment" work mode, that is, using specialized sanders, putty application machines, or paint spraying machines for different processes. While this can complete the basic construction, it has many shortcomings in practical application:

[0003] The single function leads to low efficiency, requiring frequent equipment replacement and recalibration, and the process connection is time-consuming, making it difficult to adapt to the needs of rapid processing of large-area walls.

[0004] The lifting structure is mostly a single-stage or two-stage design, which limits the working height and is prone to asynchronous lifting on both sides, causing the workbench to tilt and affecting the flatness of the wall and the uniformity of the coating.

[0005] The equipment is mostly modular, bulky, and inconvenient to move, especially in confined spaces such as small apartments or high-rise buildings, making relocation difficult.

[0006] The automation level is low, relying on manual adjustment of operation parameters and mobile equipment, resulting in high labor intensity and significant fluctuations in construction quality due to human experience.

[0007] The dust generated during sanding and the exhaust fumes from paint volatilization lack effective control, and long-term exposure can harm the respiratory health of construction workers.

[0008] In summary, existing wall treatment equipment cannot meet the demands of interior decoration for efficient, high-quality, convenient, and safe operations, and urgently needs improvement. Utility Model Content

[0037] In summary, this device integrates the putty channel 5, sanding motor 6, and paint channel 7 via the workbench 4, and is correspondingly equipped with a putty application bin 8, sanding disc 9, and paint brush 11. It can complete the three core processes of wall sanding, putty application, and paint spraying on a single machine, eliminating the need for frequent changes to specialized equipment and recalibration of the work position, significantly shortening the time between processes. Simultaneously, the putty tank 12 and paint tank 13 are directly connected to their respective channels via pumps and pipelines, ensuring continuous and smooth paint delivery. This avoids the interruptions caused by adding and changing paint in traditional separate equipment, making it particularly suitable for large-area wall treatment scenarios and effectively improving overall construction efficiency.

[0038] This device employs a three-stage nested multi-stage lifting mechanism 2, coupled with a synchronous transmission design of the driving pulley 203, driven pulley 204, and synchronous belt 205. This enables the lifting screws 210 on both sides to operate at the same speed, avoiding the tilting problem of the worktable 4 caused by poor synchronization in traditional single / two-stage lifting structures. The limiting protrusions and grooves between the lifting screw 210 and the screw sleeve further prevent the screw sleeve from rotating and shifting, ensuring a stable and reliable lifting process, effectively expanding the working height, and meeting the needs of high-rise building interior wall treatment. At the same time, the lifting mechanism 3, through the guiding cooperation of the slide rail 304 and the slider 305, allows the worktable 4 to move smoothly in the vertical direction. Combined with the stability of the threaded connection of the sanding disc 9, the synergistic effect of the strip outlet 802 of the putty application bin 8 and the rolling putty brush 803, it can ensure the smoothness of sanding, the uniformity of putty coating thickness, and the consistency of paint spraying, significantly reducing fluctuations in construction quality.

[0039] Based on the vehicle body 1, this device integrates a multi-stage lifting mechanism 2, a lifting mechanism 3, a worktable 4, a paint box, a battery box 14, and a control panel 15 into one compact structure, avoiding the problems of dispersed volume and uneven weight of traditional separate equipment. The electric drive wheels 16 at the bottom of the vehicle body 1 support multi-directional movement such as forward, backward, and turning, without the need for manual handling or external tools. It is especially suitable for the relocation needs of narrow spaces such as small apartments and high-rise building corridors, significantly reducing the difficulty of equipment relocation.

[0040] The control panel 15 is electrically connected to the electric drive wheels 16, camera device 17, and various power components (material pump, grinding motor 6, lifting / elevating motor 301), allowing for unified control of parameters such as equipment movement, lifting height, paint flow rate, and grinding speed, reducing manual operation. The camera device 17 (including lidar, camera, and ultrasonic sensors) can perceive the working environment in real time, assisting in path planning and obstacle avoidance without requiring manual adjustment of the equipment position. This significantly reduces the physical labor intensity of construction workers, while avoiding prolonged close contact with grinding dust and paint fumes, reducing occupational health risks and meeting the safety and environmental protection requirements of modern construction.

[0041] The grinding disc 9 is designed to be detachable through a threaded connection between the connecting sleeve 601 and the connecting shaft 901. It can be quickly replaced without complicated tools after wear, which shortens maintenance time compared with the traditional fixed connection structure. The paint delivery pipeline adopts a detachable form with a sealed plug-in connection. When changing different types of putty or paint, the pipeline can be directly disassembled for cleaning or replacement, avoiding pipeline blockage caused by paint residue and reducing material waste. The battery box 14 provides overall power supply without the need for an external power cord, further improving the flexibility of equipment use and reducing long-term use and maintenance costs.

[0042] This device achieves integrated and efficient operation of wall sanding, putty application, and paint spraying through the coordinated control of the entire process of "preparation-sensing-navigation-operation-detection-completion". The specific workflow is as follows:

[0043] I. Mechanical Pre-installation and Condition Inspection

[0044] Functional component assembly: According to the wall treatment task to be performed (sanding / puttying / painting), complete the assembly of the corresponding functional components. The sanding disc 9 is fixed by screwing the connecting sleeve 601 of the output shaft of the sanding motor 6 through the rear connecting shaft 901. The putty application chamber 8 is sealed and inserted into the putty channel 5 of the workbench 4 through the connecting pipe 1 804. The paint brush 11 is sealed and inserted into the paint channel 7 of the workbench 4 through the connecting pipe 2 112, ensuring that the connection of each component is firm and leak-free.

[0045] Paint and power preparation: Add the corresponding types of putty and paint to the putty and paint tanks 12 and 13 in the middle of the vehicle body 1, respectively, and check the sealing status of the tanks; confirm that the battery box 14 inside the vehicle body 1 has sufficient power to ensure the power supply needs for continuous operation of the equipment; check the pipeline connection between the putty pump 121, the paint pump 131 and the paint tank and the workbench 4 channel to ensure that the pipeline is unobstructed.

[0046] Equipment self-test: Start the system self-test program through the control panel 15 at the rear of the vehicle body 1 to check the operating status of the electric drive wheels 16, multi-stage lifting mechanism 2, lifting mechanism 3, grinding motor 6, and camera device 17, and confirm that each component is fault-free and the electrical connection is normal.

[0047] II. Task Reception and Initialization

[0048] Task instruction input: Operators input specific construction task parameters through the control panel 15, including the work area range (such as wall length and height), process requirements (such as sanding roughness, putty coating thickness, and paint spraying amount), and material type (such as putty model and paint type).

[0049] System initialization: After receiving the command, the control panel 15 automatically calls the preset operation parameter template and synchronously initializes each functional module. The putty pump 121 and paint pump 131 are preset with the corresponding paint delivery flow rate; the sanding motor 6 is preset with the speed adapted to the wall material; the multi-stage lifting mechanism 2 and the lifting mechanism 3 are reset to the initial low position to prepare for subsequent operations.

[0050] III. Environmental Perception and Map Building

[0051] Real-time environmental scanning: The camera device 17 (including lidar, camera and ultrasonic sensor) on one side of the vehicle body is activated to perform a 360° real-time scan of the construction area and collect environmental data such as wall flatness, obstacle position (such as corners, sockets, doors and windows), and space height.

[0052] Precise map construction: The system combines the environmental data collected by the camera device 17 to automatically generate a three-dimensional map of the work area, marking the specific range of the wall to be processed and the coordinates of the obstacles to be avoided. Based on the wall height data, the maximum lifting height of the multi-level lifting mechanism 2 is initially planned, providing a basis for subsequent path planning.

[0053] IV. Route Planning and Navigation Positioning

[0054] Optimal path generation: Based on the 3D map and task parameters, the control panel 15 automatically plans the movement path of the equipment. Based on the principles of "full coverage, no repetition, and obstacle avoidance", it plans the movement route from the initial position to the starting point of the wall treatment, as well as the operation trajectory along the wall treatment area (such as the collaborative path of horizontal translation and vertical lifting).

[0055] Automatic navigation to position: The control panel 15 sends navigation commands to the electric drive wheels 16, which drive the vehicle body 1 to move along the planned path. During the process, the camera device 17 provides real-time feedback on the equipment's position information. The control panel 15 dynamically adjusts the wheel steering and speed to ensure that the equipment accurately stops at the first wall treatment position, completing the pre-operation positioning.

[0056] V. Execution of Wall Treatment Work

[0057] According to the sequence of operations in the task instructions (e.g., sanding first, then puttying, then painting), control panel 15 coordinates the multi-stage lifting mechanism 2, the hoisting mechanism 3, and the corresponding functional components to start the operation, specifically executing in three working conditions:

[0058] (1) Wall sanding operation

[0059] Height Adjustment: Control panel 15 starts the drive motor 202 of the multi-stage lifting mechanism 2. The motor output drives the active pulley 203 to rotate, which is transmitted to the driven pulley 204 of the lifting screws 210 on both sides through the synchronous belt 205, so that the lifting screws 210 on both sides rotate synchronously. The lifting screws 210 drive the first-stage lifting seat 207, the second-stage lifting seat 208, and the third-stage lifting sleeve 213 to rise in sequence until the height of the grinding disc 9 is adapted to the area of ​​the wall to be ground. Then the lifting motor 301 starts, drives the lifting screw 302 to rotate, and drives the worktable 4 (and the grinding disc 9) to make vertical fine adjustments along the slide rail 304 through the nut seat 303 to ensure that the grinding disc 9 is in contact with the wall.

[0060] Sanding execution: Start the sanding motor 6. The motor output shaft drives the connecting sleeve 601 and the sanding disc 9 to rotate at high speed. At the same time, the electric drive wheel 16 drives the vehicle body 1 to move slowly laterally along the planned trajectory, so that the sanding disc 9 evenly covers the sanding area of ​​the wall. During the process, the camera device 17 monitors the state of the sanding surface in real time. The control panel 15 fine-tunes the sanding speed and the moving speed of the vehicle body 1 according to the feedback to ensure the smoothness of the sanding.

[0061] (2) Putty application work

[0062] Height and position calibration: Repeat the adjustment steps of the multi-stage lifting mechanism 2 and lifting mechanism 3 to align the rolling putty brush 803 of the putty application chamber 8 with the area of ​​the wall to be coated, and ensure that the strip outlet 802 is parallel and in contact with the wall.

[0063] Putty delivery and application: Start the putty pump 121, the pump body draws putty from the putty paint tank 12, delivers it through the pipeline to the putty channel 5 of the workbench 4, and then enters the putty application chamber 8 through the connecting pipe 804; the putty flows out from the strip outlet 802, and at the same time the rolling putty brush 803 rotates as the vehicle body 1 moves laterally, so as to evenly apply the putty to the wall surface; the control panel 15 adjusts the flow rate of the pump in real time to match the moving speed of the vehicle body 1, so as to avoid putty accumulation or missed application.

[0064] (3) Paint spraying operation

[0065] Height and position calibration: Adjust the height of the worktable 4 by using the multi-stage lifting mechanism 2 and the lifting mechanism 3 to align the paint brush 11 with the area of ​​the wall to be sprayed, ensuring that the strip opening of the paint hollow seat 111 is adapted to the wall surface.

[0066] Paint delivery and application: The paint pump 131 is started, and the pump body draws paint from the paint tank 13. The paint is then transported through the pipeline, paint channel 7, and connecting pipe 2 112 to the paint hollow seat 111. The paint seeps out from the strip opening to the paint brush 11. The electric drive wheel 16 drives the vehicle body 1 to move along the planned trajectory, and the paint brush 11 rotates synchronously to complete the wall painting. The control panel 15 finely adjusts the flow rate of the pump and the moving speed of the vehicle body 1 according to the paint coverage feedback from the camera device 17 to ensure that the paint coating is uniform and without any leaks.

[0067] VI. Quality Inspection and Feedback Correction

[0068] Real-time detection: After each section of wall surface is processed (such as a horizontal area), the camera device 17 automatically captures an image of the processed wall surface, and combines it with the LiDAR to detect the surface flatness and coating thickness, and transmits the data to the control panel 15.

[0069] Feedback and Correction: Control panel 15 compares the detection data with the preset process standards. If there are problems such as uneven sanding, missing putty, or insufficient paint thickness, it automatically plans a secondary operation path, drives the equipment back to the problem area, and repeats the corresponding operation steps for correction. If the detection is qualified, it proceeds to the next area for operation.

[0070] VII. Task Completion and Conclusion

[0071] Task termination judgment: When the camera device 17 detects that all preset working areas have been processed and the quality is qualified, the control panel 15 determines that the task has ended and automatically stops the operation of each functional component.

[0072] Equipment reset and report generation: Multi-stage lifting mechanism 2 and lifting mechanism 3 are reset to their initial low positions; Control panel 15 generates a task completion report, displaying data such as operation time, putty / paint consumption, and equipment operating status; Electric drive wheels 16 drive vehicle body 1 back to the charging / standby area along the planned path, waiting for the next task instruction.

[0073] Subsequent maintenance: Operators can disassemble the putty / paint delivery pipeline and sanding disc 9 for cleaning or replacement, and replenish the materials in the paint tank to prepare for subsequent operations.
