Description

Technical Field

[0001] The invention relates to the technical field of wall grinding, and in particular to a device for grinding curved wall in building construction. Background Art

[0002] In the decoration process, grinding the wall after putty construction is an important process, because the wall after putty construction may be uneven, such as bumps, irregular particles, etc., through grinding, these small flaws and bumps can be removed to make the wall smoother and flatter. The flat wall can ensure that the latex paint reflects light more evenly and has a better visual effect. At the same time, grinding can increase the micro-roughness of the wall and provide more micro-anchoring points, thereby enhancing the adhesion of the paint. In this way, the latex paint after painting is more solid and not easy to fall off, and after grinding The wall is easier to paint, and the latex paint coating is more uniform. When grinding the wall, using machine grinding can improve the grinding efficiency, but because the machine grinding head is a disc structure, the machine's movement trajectory does not match the curvature of the wall. Especially when encountering curved wall grinding, it cannot fit the curved shape well for uniform grinding, resulting in inconsistent grinding degrees at different positions on the curved wall. In some places, excessive grinding leads to excessive removal of wall material and pits. In some places, insufficient grinding still has obvious protrusions or rough surfaces, which reduces the grinding efficiency. Summary of the invention

[0016] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] The present invention provides Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Fig.13 A curved wall grinding device for building construction shown in the figure comprises a curved wall 1, a grinding assembly 2 is provided on one side of the curved wall 1, and the grinding assembly 2 is used to fit the curved surface of the curved wall 1 and make the motion trajectory of the grinding assembly 2 match the curvature of the curved wall 1; The grinding component 2 includes a stabilizing seat 21 and a grinding cylinder 22, on which an adsorption component 3 and a blowing component 4 are respectively provided, and the adsorption component 3 and the blowing component 4 are used to adsorb and blow away the dust near the upper and lower ends of the grinding component 2, to ensure that the dust flying upwards generated during grinding is effectively discharged by the adsorption component 3, and the dust of the grinding component 2 and the dust near the arc wall 1 are blown from bottom to top, and two groups of synchronization components 5 are commonly connected between the grinding component 2 and the adsorption component 3 and the blowing component 4, and the synchronization component 5 is used to synchronously move the grinding cylinder 22, the adsorption component 3 and the blowing component 4 up and down along one side of the stabilizing seat 21, so that the grinding position between the grinding cylinder 22 and the arc wall 1 can be adjusted while the position of the stabilizing seat 21 remains unchanged, and the adsorption component 3 and the blowing component 4 are both connected with a diagonal support component 7: the grinding component 2 includes two cone-attached grinding cylinders 24, a grinding cylinder 22 movably arranged on one side of the arc wall 1 and a support component 7 installed on the outside of the grinding cylinder 22 The stable seat 21 is provided with a plurality of grinding rods 23 fixedly connected to the outside of the grinding cylinder 22. A handle 26 is installed on one side of the stable seat 21. A first servo motor 27 is installed at the bottom end of one of the attached cone grinding cylinders 24. The first servo motor 27 is used to drive the attached cone grinding cylinder 24, the grinding cylinder 22 and the grinding rod 23 to move in a circular motion. The diagonal support assembly 7 includes two inclined slot seats 71 symmetrically fixedly connected to the outside of the connection shell 32 and the limiting shell 41 and two connecting shaft columns 73 arranged on one side of the two inclined slot seats 71. The outsides of the two connecting shaft columns 73 are sleeved with inclined slot rods 74, and a tension spring 72 is commonly connected between the two inclined slot rods 74. The side of the inclined slot rod 74 close to the arc wall 1 is fixedly connected with a connecting tube 75, and the connecting tube 75 is used to guide and support the grinding cylinder 22 when it is attached to one side of the arc wall 1. The grinding cylinder 22 and the attached cone grinding cylinder 24 are combined to form a cone wheel structure, so that the grinding cylinder 22 and the attached cone grinding cylinder 24 can better adapt to the curve change of the arc surface of the arc wall 1, so that the grinding cylinder 22 and the attached cone grinding cylinder 24 can maintain a closer contact with the wall surface, ensuring that the wall surface is evenly ground; in addition, when the grinding cylinder 22 and the attached cone grinding cylinder 24 are in contact with the arc wall 1, different pressures will be generated. In the central area of ​​the grinding cylinder 22, a larger pressure can better grind the raised part of the wall surface. In the edge area of ​​the grinding cylinder 22 and the attached cone grinding cylinder 24, a smaller pressure can avoid excessive grinding and prevent the wall surface from being dented or damaged, so that the gradual grinding pressure helps to improve the uniformity of grinding; When it is necessary to grind the surface of the arc wall 1, the user first holds the handle 26 to provide stable support for the whole, and then moves the grinding cylinder 22 close to the surface of the arc wall 1. At this time, the two connecting cylinders 75 are in contact with the surface of the arc wall 1 in advance, and then the two connecting cylinders 75 are forced to drive the two inclined groove rods 74 and the two connecting shaft columns 73 to move relative to or towards each other along the two inclined groove seats 71. At this time, the two connecting cylinders 75 move towards each other to pull the tension spring 72 to move synchronously, so that the postures of the two connecting cylinders 75 outside the adsorption component 3 and the blowing component 4 are adjusted, so that the two connecting cylinders 75 are adjusted. The grinding cylinder 22 slowly moves to the arc wall 1 The surface of the arc wall 1 is close to and fits, which can provide an additional positioning point for the grinding cylinder 22, making it more stable during the grinding process and accurately maintaining the set grinding position. As the first servo motor 27 drives the two attached cone grinding cylinders 24 and the grinding cylinder 22 to rotate synchronously, the grinding cylinder 22 makes a circular motion between the arc wall 1 and the stable seat 21, and then the rotation of the grinding cylinder 22 drives a plurality of grinding rods 23 to rotate synchronously, and then the grinding rod 23 performs a grinding operation on the surface of the arc wall 1, so that the movement trajectory of the grinding cylinder 22 and the grinding rod 23 can match the curvature of the arc wall 1, ensuring that the grinding cylinder 22 and the grinding rod 23 grind the surface of the arc wall 1 evenly.

[0018] refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the adsorption assembly 3 includes a connection shell 32 installed on the top of the attached cone grinding cylinder 24 and a rotating rod 31 connected to the top of the attached cone grinding cylinder 24, and the rotating rod 31 is rotatably connected to the inside of the connection shell 32, the inside of the connection shell 32 is fixedly connected with a filter rack 35, and the filter rack 35 is sleeved on the outside of the rotating rod 31, and the outside of the rotating rod 31 is fixedly connected with a plurality of dust suction impellers 34, and the connection shell 32 and the stable seat 21 are commonly connected with a dust suction pipe 33 communicated with the inside thereof, and a fitting groove 37 is provided on one side of the stable seat 21. The interior of the connecting shell 37 is connected with a collecting frame 38, and the collecting frame 38 is used to discharge the dust near the grinding cylinder 22, and the outside of the connecting shell 32 is fixedly connected with a supporting rod 36; the blowing assembly 4 includes a receiving rod 42 arranged between the attached cone grinding cylinder 24 and the first servo motor 27, and the outside of the receiving rod 42 is fixedly connected with a blowing fan blade 43, and the outside of the first servo motor 27 is fixedly sleeved with a limiting shell 41, and the receiving rod 42 and the blowing fan blade 43 are both located inside the limiting shell 41, and the outside of the limiting shell 41 is fixedly connected with a bottom bracket 44; The collecting frame 38 is square and has an arc-shaped structure on one side, and the shape of the collecting frame 38 is consistent with the fitting groove 37, so that the collecting frame 38 is embedded in the fitting groove 37 with a moving gap, so that the collecting frame 38 can be flexibly installed in the fitting groove 37; When the grinding cylinder 22 is rotating to grind the surface of the arc wall 1, the first servo motor 27 drives the attached cone grinding cylinder 24 to move in a circular motion, and then the attached cone grinding cylinder 24 drives the rotating rod 31 to rotate synchronously inside the connecting shell 32 under the action of rotation. At this time, the rotation of the rotating rod 31 drives the dust suction impeller 34 to rotate synchronously, and the rotation of the dust suction impeller 34 generates a negative pressure effect inside the connecting shell 32, and under the negative pressure effect generated by the dust suction impeller 34, the air near the grinding cylinder 22, the attached cone grinding cylinder 24 and the connecting shell 32 together with the dust are discharged from the connecting shell 32 to the inside of the dust duct 33, and the dust inside the dust duct 33 is discharged to the inside of the fitting groove 37. At the same time, the collecting frame 38 can collect the discharged dust in a centralized manner for cleaning, and the rotation of the first servo motor 27 drives the blowing fan blades 43 to rotate synchronously, and then the blowing fan blades 43 disturb the air during rotation to form a directional airflow. At this time, the blowing fan blades 43 can blow the dust near the attached cone grinding cylinder 24, the grinding cylinder 22 and the arc wall 1, so as to disperse the dust near the attached cone grinding cylinder 24, the grinding cylinder 22 and the arc wall 1 from bottom to top, and can blow the dust from bottom to top, so that the grinding cylinder 22 and the wall surface are kept relatively clean, so that the grinding cylinder 22 has a better fit with the arc wall 1, and ensures that the grinding cylinder 22 can stably grind the surface of the arc wall 1.

[0019] refer to Figure 8-Figure 12As shown, the synchronization component 5 includes two support arms 55 fixedly connected to the support rod 36 and the bottom bracket 44 near one end of the stable seat 21 and a synchronization chamber 51 opened on one side of the stable seat 21, the synchronization chamber 51 is internally rotatably connected with a threaded column 54, the synchronization chamber 51 is internally fixedly connected with a second servo motor 58, and the second servo motor 58 is used to drive the threaded column 54 to rotate, one end of the two support arms 55 passes through the interior of the synchronization chamber 51 and is fixedly connected with two moving rings 56 that match the threaded column 54, and the threaded column 54 is provided with a shaking component 6 for intermittently pushing the collection frame 38 to reciprocate; the top and bottom of the stable seat 21 are provided with positioning grooves 53 for the support rod 36, the bottom bracket 44 and the support arm 55 to move, the positioning groove 53 is provided with a guide groove 52 that communicates with the interior of the synchronization chamber 51 for guiding the movement of the support arm 55, and the support A centering rod 57 is fixedly connected to one side of the arm 55, and the centering rod 57 and the support arm 55 are combined to form a cross-shaped structure for guiding the support rod 36 and the bottom bracket 44 to move stably in the positioning groove 53; the shaking assembly 6 includes a cam plate 61 fixedly sleeved on the middle part of the outer portion of the threaded column 54, a chimeric frame 62 slidably connected in the chimeric groove 37, and a connecting cavity 64 provided on one side of the collection frame 38 for the chimeric frame 62 to be embedded, a displacement groove 65 communicating with the interior of the connecting cavity 64 is provided on one side of the collection frame 38, a displacement rod 66 is fixedly connected to one side of the chimeric frame 62, and one end of the displacement rod 66 extends to the interior of the synchronization cavity 51 and is fixedly connected to a semi-arc plate 67 that matches the cam plate 61, a crescent groove 68 is provided on the outer portion of the cam plate 61 for the semi-arc plate 67 to move, and a spring 63 is commonly connected between the chimeric frame 62 and the chimeric groove 37; In addition, the contact position of the grinding cylinder 22 and the arc wall 1 can be adjusted while the position of the stabilizing seat 21 remains unchanged, which can adapt to the on-site grinding environment. In a narrow construction space, if the stabilizing seat 21 is frequently moved, the collision between the stabilizing seat 21 and the grinding cylinder 22 and the surrounding objects increases, and the distance between the stabilizing seat 21 and the ground is reduced, which is not conducive to the user's stable grip of the handle 26, so that the operating space of the stabilizing seat 21 and the grinding cylinder 22 on the arc wall 1 is limited, resulting in excessive shaking of the grinding cylinder 22 when grinding the arc wall 1. By adjusting the position of the grinding cylinder 22 by moving it up and down along one side of the stabilizing seat 21, the user can stably grip the handle 26, ensuring that the grinding cylinder 22 can maintain relative stability with the arc wall 1, which helps to maintain the consistency of grinding and make the grinding effect of the arc surface more uniform. When the construction environment on site is limited and the position of the stabilizing seat 21 needs to remain unchanged while adjusting the contact position of the grinding cylinder 22 along one side of the arc wall 1, the threaded column 54 is driven by the second servo motor 58 to rotate synchronously in the synchronous cavity 51, and then the threaded column 54 rotates to drive the two moving rings 56 to move synchronously downward or upward along the synchronous cavity 51. At this time, the two moving rings 56 move synchronously downward along the synchronous cavity 51, driving the support rod 36 and the bottom bracket 44 to move synchronously downward, and the support rod 36 moves downward to drive the support arm 55 installed outside thereof to move downward along the positioning groove 53 and the guide groove 52 along the inside of the synchronous cavity 51. At this time, the part of the centering rod 57 on the support rod 36 exposed inside the positioning groove 53 is constantly decreasing, and The bottom bracket 44 moves downward, driving the support arm 55 installed outside it to move along the inside of the synchronous cavity 51 toward the inside of the positioning groove 53 and the guide groove 52. At this time, the part of the centering rod 57 on the bottom bracket 44 exposed inside the positioning groove 53 is constantly increasing, so that the stabilizing seat 21 adjusts the contact position of the grinding cylinder 22 and the arc wall 1 without changing its position, and drives the cam plate 61 to rotate synchronously through the rotation of the threaded column 54. Then the cam plate 61 rotates to move its protruding part closer to the outside of the semi-arc plate 67. At this time, the crescent groove 68 opened on the cam plate 61 and the protruding part of the cam plate 61 rotate on the outside of the semi-arc plate 67, and the cam plate 61 and the semi-arc plate 67 are used to push the semi-arc plate 67 and the displacement rod 66 along the synchronous cavity 5 1. The engaging groove 37 and the displacement groove 65 move, and the displacement rod 66 moves to push the engaging frame 62 to move synchronously, and the engaging frame 62 is embedded and connected with the connecting cavity 64, so that the engaging frame 62 moves and drives the collection frame 38 synchronously, and the spring 63 generates elasticity and relatively contracts under the movement of the engaging frame 62. As the cam plate 61 continues to move, its protruding part and the semi-arc plate 67 are staggered and lose contact, and then the crescent groove 68 moves to the vicinity of the semi-arc plate 67, and then the spring 63 itself elastically stretches to give a thrust to one side of the engaging frame 62, pushing the engaging frame 62 and the collection frame 38 to move and reset along the engaging groove 37, and the engaging frame 62 moves and pushes the displacement rod 66 and the semi-arc plate 67 to move and reset, so that the outer part of the semi-arc plate 67 is aligned with the crescent groove 6 8 forms a conflict inside, during which the collection frame 38 reciprocates once along the fitting groove 37. In addition, the cam plate 61 drives the crescent groove 68 to move synchronously under continuous rotation, and then the inside of the collection frame 38 moves between the fitting groove 37 and pushes the semi-arc plate 67 to move. At this time, the outside of the semi-arc plate 67 moves out of the inside of the crescent groove 68 and conflicts with the outside of the cam plate 61, and the semi-arc plate 67 also produces a small displacement when moving out of the inside of the crescent groove 68, so that the cam plate 61 again contacts its external protruding part with the semi-arc plate 67 under rotation, and reciprocates in this way, so that the collection frame 38 cooperates with the grinding cylinder 22 when collecting dust and not cleaning it, so that the grinding cylinder 22 drives the collection frame 38 to move intermittently and synchronously during the adjustment process.Make full use of the space of the collection frame 38 to improve the capacity and efficiency of dust collection, collect dust more effectively, and ensure the continuity of grinding operations.

[0020] Working principle: When in use; The user holds the handle 26 to provide stable support for the whole, and then moves the grinding tube 22 close to the surface of the curved wall 1. At this time, the diagonal support component 7 is in contact with the surface of the curved wall 1 in advance, and the diagonal support component 7 adapts to the curvature of the surface of the curved wall 1 after contacting the curved wall 1, so that the posture of the diagonal support component 7 outside the adsorption component 3 and the blowing component 4 is adjusted, which can provide an additional positioning point for the grinding tube 22, making it more stable during the grinding process.

[0021] The first servo motor 27 drives the two attached cone grinding cylinders 24 and the grinding cylinder 22 to rotate synchronously, so that the grinding cylinder 22 moves in a circle between the arc wall 1 and the stable seat 21, and then the rotation of the grinding cylinder 22 drives a number of grinding rods 23 to rotate synchronously. At this time, the grinding rods 23 perform a grinding operation on the surface of the arc wall 1, and the first servo motor 27 drives the blowing component 4, the grinding cylinder 22 and the adsorption component 3 to cooperate with each other during rotation. The blowing component 4 is used to blow and disperse the dust near the grinding cylinder 22 and the arc wall 1 from bottom to top, and the adsorption component 3 is used to adsorb the dust above the grinding cylinder 22, so as to discharge the dust near the grinding cylinder 22, so that the grinding cylinder 22 and the surface of the arc wall 1 are evenly polished.

[0022] The synchronous component 5 can drive the grinding cylinder 22, the adsorption component 3 and the blowing component 4 to move synchronously along one side of the stable seat 21. Then, when the stable seat 21 needs to remain in position, the contact position of the grinding cylinder 22 along the side of the arc wall 1 is adjusted, so that the user can hold the handle 26 tightly to ensure that the grinding cylinder 22 can achieve stable grinding of the surface of the arc wall 1. The driving of the synchronous component 5 drives the shaking component 6 to cooperate with the adsorption component 3, so that the adsorption component 3 can move and cooperate with the grinding cylinder 22 when collecting dust but not cleaning it, so that the grinding cylinder 22 can drive the adsorption component 3 to move intermittently and synchronously during the adjustment process, so as to make full use of the space of the adsorption component 3, improve the capacity and efficiency of dust collection, collect dust more effectively, and ensure the continuity of the grinding operation.
