[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: Figure 1-5 As shown, this utility model provides an intelligent grinding robot for construction, including a walking mechanism 1. The walking mechanism 1 provides the robot with mobility, enabling it to move flexibly to different work areas on the construction site. A vertical shell 5 is fixedly connected to the upper surface of the walking mechanism 1. A lifting mechanism 3 is provided inside the vertical shell 5. The lifting mechanism 3 realizes the rapid and precise adjustment of the height of the grinding head body 4 to meet the grinding needs of different building heights and wall heights.

[0016] A mounting shell 9 is fixedly connected to one side of the lifting mechanism 3, and a DC motor 6 is fixedly installed inside the mounting shell 9. A support base 7 for use with the DC motor 6 is fixedly installed inside the mounting shell 9. The DC motor 6 is fixedly installed on the upper surface of the support base 7. The support base 7 provides stable support for the DC motor 6 and reduces vibration during motor operation. The output end of the DC motor 6 passes through the mounting shell 9 and is fixedly connected to a retaining sleeve 8. The DC motor 6 drives the retaining sleeve 8 to rotate through the output end, providing grinding power to the grinding head body 4.

[0017] The ferrule 8 is movably engaged with the grinding head body 4 on one side. A quick-connect assembly 2 is provided between the ferrule 8 and the grinding head body 4. The quick-connect assembly 2 enables a quick and secure connection between the grinding head body 4 and the ferrule 8. Compared with the traditional bolt installation method, it greatly shortens the replacement time and avoids the problem of loosening or falling off due to the unstable installation of the grinding head body 4, thus ensuring the continuity and efficiency of the grinding work.

[0018] The quick-installation assembly 2 includes symmetrically distributed locking blocks 25, which are symmetrically fixedly installed on one side of the grinding head body 4. The outer surface of the sleeve 8 is symmetrically provided with slots 21 for use with the locking blocks 25. The locking blocks 25 and the slots 21 are movably locked together. The locking blocks 25 are magnetic blocks, and the slots 21 are magnetic grooves. The locking blocks 25 and the slots 21 are magnetically connected. The locking blocks 25 and the slots 21 are connected by magnetic attraction. During installation, they can be automatically attracted and positioned by magnetic force, eliminating the need for manual precise alignment and simplifying the installation steps.

[0019] An electric push rod 22 is fixedly installed inside the ferrule 8, and the output end of the electric push rod 22 is fixedly connected to a plug rod 24. The inner wall of the grinding head body 4 and the inner wall of the ferrule 8 are respectively provided with a through groove 26 and a positioning groove 23 for use with the plug rod 24. The plug rod 24 is movably inserted into the through groove 26 and the positioning groove 23. The electric push rod 22 pushes the plug rod 24 into the through groove 26 and the positioning groove 23 to form a mechanical lock, which further enhances the connection stability between the grinding head body 4 and the ferrule 8 and effectively resists high-frequency vibration during the grinding process. The outer surface shape of the plug rod 24 matches the inner wall shape of the through groove 26 and the positioning groove 23. The precise matching design of the plug rod 24 with the through groove 26 and the positioning groove 23 ensures that the grinding head body 4 will not shift after installation, thus ensuring grinding accuracy.

[0020] The lifting mechanism 3 includes a servo motor 31, which is fixedly installed inside the vertical shell 5. The output end of the servo motor 31 is fixedly connected to a lead screw 35. The servo motor 31 drives the lead screw 35 to rotate. A slider 32 is threaded on the outer surface of the lead screw 35, which drives the slider 32 to move up and down along the lead screw 35. The outer surface of the slider 32 is slidably connected to the inner cavity of the vertical shell 5 to ensure the accuracy of the slider 32's movement direction. The bottom end of the lead screw 35 is rotatably connected to the inner cavity of the vertical shell 5 to ensure the smoothness of the lead screw 35's rotation.

[0021] A connecting plate 34 is fixedly connected to one side of the slider 32. A vertical groove 33 is provided on one side of the vertical shell 5 to cooperate with the connecting plate 34. The connecting plate 34 is slidably connected to the inner wall of the vertical groove 33. The vertical groove 33 guides and limits the connecting plate 34, ensuring the stability and straightness of the slider 32 when it drives the mounting shell 9 to rise and fall. The connecting plate 34 passes through the vertical groove 33 and is fixedly connected to one side of the mounting shell 9. By connecting the connecting plate 34 to the mounting shell 9, the height of the grinding head body 4 can be quickly adjusted, so that the grinding head body 4 can accurately grind at different heights.

[0022] Working principle: First, the walking mechanism 1 serves as the robot's mobile carrier. It can move flexibly to different work areas by driving the wheels or tracks to rotate through the built-in drive system, according to the terrain conditions of the construction site.

[0023] When it is necessary to adjust the height of the grinding head body 4, the servo motor 31 in the lifting mechanism 3 is started, and its output end drives the lead screw 35 to rotate. Since the lead screw 35 and the slider 32 are threadedly engaged, the slider 32 will move linearly along the axial direction of the lead screw 35.

[0024] The outer surface of the slider 32 is slidably connected to the inner cavity of the vertical shell 5 to ensure the stability and straightness of the movement. At the same time, the bottom end of the lead screw 35 is rotatably connected to the inner cavity of the vertical shell 5 to provide support for the rotation. The connecting plate 34 fixedly connected to one side of the slider 32 slides in the vertical groove 33, transmitting the movement of the slider 32 to the mounting shell 9, which in turn drives the DC motor 6, the ferrule 8 and the grinding head body 4 mounted on the mounting shell 9 to rise and fall synchronously, realizing the rapid and precise adjustment of the grinding height to adapt to the grinding needs of walls of different heights.

[0025] When installing the grinding head body 4, the quick-release assembly 2 is used to first align the symmetrically distributed locking blocks 25 on one side of the grinding head body 4 with the locking groove 21 on the outer surface of the sleeve 8. Since the locking blocks 25 are magnetic blocks and the locking groove 21 is a magnetic groove, the two will automatically attract each other and be initially positioned by magnetic force.

[0026] Subsequently, the electric push rod 22 inside the ferrule 8 is activated, and its output end pushes the insertion rod 24 to extend. The insertion rod 24 passes through the through groove 26 on the inner wall of the grinding head body 4 and the positioning groove 23 on the inner wall of the ferrule 8 in sequence. The outer surface shape of the insertion rod 24 matches the inner wall shape of the through groove 26 and the positioning groove 23, forming a mechanical lock, completing the stable connection between the grinding head body 4 and the ferrule 8, and realizing quick installation.

[0027] After the grinding head body 4 is installed, the walking mechanism 1 and the lifting mechanism 3 work together. The walking mechanism 1 moves at a low speed and moves horizontally along the wall, while the lifting mechanism 3 adjusts the height of the grinding head body 4 in real time according to the undulation of the wall.

[0028] At the same time, the DC motor 6 starts, and its output drives the ferrule 8 to rotate at high speed, which in turn drives the grinding head body 4 to grind the wall. Through the precise cooperation of multiple components, the robot can complete the wall grinding task efficiently and evenly.

[0029] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
