Description

Technical Field

[0001] The invention belongs to the field of wall surface construction, in particular to a thickness control device for interior wall plastering. Background Art

[0002] Wall plastering is an important part of construction, which is not only related to the beauty of the building, but also to the service life of the building and the comfort of living. The steps of plastering include: base coat: first apply a thicker layer of base coat, usually about 10-15mm thick, to level the wall; leveling: use a scraper or spatula to scrape the base coat flat to ensure the wall is flat; plastering: after the base coat is dry to a certain extent, apply a thinner layer of surface coat, usually about 2-5mm thick, to further level and decorate the wall; calendering: before the surface coat is initially solidified, use a spatula to perform calendering to eliminate smear marks and improve the smoothness and beauty of the wall;

[0003] The average thickness of ordinary plastering should not be greater than 20mm, and the average thickness of high-grade plastering should not be greater than 25mm. The thickness of plastering is crucial to ensuring the quality, durability and aesthetics of the building. If the plastering layer is too thick, it is easy to cause quality problems such as bulging and falling off; if the plastering layer is too thin, it may not be able to effectively cover the unevenness of the wall, resulting in the final wall surface being not smooth and flat enough, so the thickness of the plastering needs to be controlled.

[0004] In traditional interior wall plastering work, due to the lack of reference, the thickness of the plastering can only be determined by the experience of the staff, or an anchor point is set first, and the coil is used to measure the distance from the interior wall to the anchor point. During the plastering process, the distance from the anchor point to the wall after plastering is continuously measured to effectively control the thickness of the plastering. However, the overall operation process is relatively complicated, and it is necessary to continuously measure the distance from the anchor point to each area of ​​the wall to calculate the thickness of the difference plastering, which results in a long operation time and affects the efficiency of plastering.

[0005] To this end, the present invention provides a thickness control device for interior wall plastering. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the thickness control device of interior wall plastering described in the present invention comprises a laser rangefinder, a servo motor 1 and a servo motor 2 for adjusting the direction of the laser rangefinder are arranged on the outer side of the laser rangefinder, a moving platform is arranged on the outer side of the laser rangefinder, four electric wheels for driving the moving platform to move are arranged on the outer side of the moving platform, two negative pressure holes penetrating to the bottom are opened on the top surface of the moving platform, a negative pressure fan is arranged in the negative pressure hole, and a camera for locating the position of the moving platform is arranged at the bottom of the moving platform;

[0008] Through the setting of the laser rangefinder, the laser rangefinder is first fixed in a position facing the inner wall before plastering, and then the laser rangefinder emits a laser to measure the distance from the device to the wall. The laser rangefinder is driven to rotate by servo motor 1 and servo motor 2, so that the laser rangefinder can make the laser emission end face every corner of the wall without moving its own position. A measurement program can be formulated, and multiple points can be preset to measure the distance from the laser rangefinder to multiple points on the wall. Then the plastering work can be started. When the plastering is halfway through, the laser rangefinder starts to measure the distance from the device to the wall at this time. By measuring multiple points and comparing them with the distance from the device to the wall before plastering, the thickness of the plastering can be calculated. The operator can wear the terminal device to receive the measurement data of the laser rangefinder, so as to know the thickness of the plastering, and use the laser rangefinder again in the final finishing stage. Measure and obtain the plastering thickness at this time. By increasing or grinding, the thickness of the plastering can be controlled more accurately. In order to ensure that the anchor point fixed by the laser rangefinder remains stationary, the laser rangefinder is carried on a mobile platform. The mobile platform can control itself to move through electric wheels, and after moving into position, the negative pressure fan is started to generate negative pressure at the bottom of the mobile platform, thereby adsorbing and fixing the mobile platform, making the mobile platform unable to move. In this way, after selecting the anchor point, you can first mark the anchor point, and use a camera to observe the marked position, so that the mobile platform and the laser rangefinder can be fixed in place and cannot be easily moved. When it is necessary to plaster other inner walls, the mobile platform is controlled by the drive of the electric wheel to perform the transfer work. Through this setting, the effect of accurately controlling the thickness of the inner wall plastering is achieved, and the whole process has a high degree of automation, fewer operating steps, and can be completed relatively easily.

[0009] Preferably, the laser emitting end of the laser rangefinder is arranged horizontally, the output end of the servo motor 1 is fixedly connected to the outer side of the laser rangefinder, the servo motor 1 is used to drive the laser rangefinder to rotate on the vertical plane, the outer side of the servo motor 1 is fixedly connected with a support frame, the top output end of the servo motor 2 is fixedly connected to the support frame, and the servo motor 2 is used to drive the laser rangefinder to rotate on the horizontal plane. After the anchor point is determined, the laser rangefinder is first made to face the wall. The position of the anchor point is generally selected on the horizontal midpoint plane of the wall, so that the rotation angle of the laser rangefinder to both sides of the wall is the same, which is convenient for adjustment; the direction of the laser rangefinder on the vertical plane is adjusted by the servo motor 1, and the direction of the laser rangefinder on the horizontal plane is controlled by the servo motor 2. The cooperation of the two can make the laser rangefinder face every corner of the wall, ensuring the accuracy of the measurement, thereby assisting in the control of the thickness of the plastering.

[0010] Preferably, a filling capsule is fixedly connected to the outer side of the movable platform, the interior of the filling capsule is hollow, the surface of the filling capsule is made of wear-resistant material, a one-way valve is fixedly connected to the bottom of the negative pressure hole, and four bending arms for connecting to electric wheels and controlling the lifting of the movable platform are arranged on the top of the movable platform. A pressure relief solenoid valve connected to the bottom surface is installed on the top surface of the movable platform. The plastering process of the inner wall is generally when the house is under decoration. At this time, the ground is full of decoration equipment, and the operator will also walk around. The device not only occupies a certain space, but is also easily damaged by impact. Through the setting of the filling capsule, the movable platform can be adsorbed by the negative pressure generated by the negative pressure fan, so the movable platform can be moved on the wall. Let the movable platform move to the top of the wall and let the device hang upside down on the wall. During the movement, the bending arm props up the entire movable platform so that the filling capsule does not touch the wall. Wall, when the mobile platform moves to the anchor point, the bending arm bends to make the filling bag fit against the wall, increasing the speed of the negative pressure fan and thus increasing the suction at the bottom of the mobile platform. Since the filling bag is hollow and deformable, it can be fitted and sealed even on the roughest cement surface. With the setting of the one-way valve, a closed space is formed between the mobile platform and the wall. Even if the negative pressure fan is turned off, since the one-way valve can only flow in one direction, the mobile platform will be adsorbed on the wall under the action of negative pressure. When the mobile platform needs to move, the pressure relief solenoid valve is opened and the negative pressure fan is turned on at the same time to generate a certain suction, so that the bending arm drives the mobile platform away from the wall, so that the mobile platform can be moved. Through this setting, the device can be fixed on the top of the wall, which not only does not occupy the ground space, but also greatly reduces the problem of the position being changed or the equipment being damaged due to human influence after the device is fixed.

[0011] Preferably, the top of the electric wheel is installed at the end of the bending arm, and the top of the bending arm is rotatably connected to the moving platform. The bending arm is arranged in sections, and the bending arms at two adjacent ends are rotatably connected, and a torsion spring is provided at the rotatable connection. A lifting column for driving the bending arm to rotate is provided on the top of the moving platform. The bending arm can be controlled to rotate by lifting and lowering the lifting column. As the bending arm rotates, the moving platform can be lifted up away from the wall, or the bottom of the moving platform can be pressed against the wall. This is suitable for the moving process and fixing process of the moving platform. The bending arm is arranged in sections, and the bending between each section will accumulate elastic potential energy under the action of the torsion spring. In this way, it can be ensured that no matter how the bending arm rotates, the bending arm can be adaptively bent, so that the electric wheel always presses against the wall, and the electric wheel can normally drive the moving platform to move.

[0012] Preferably, four transmission racks are fixedly connected to the outer side of the lifting column, a gear is fixedly connected to the top end of the bending arm, the gear is meshed with the transmission rack, both ends of the gear are rotatably connected to the moving platform, a hydraulic rod is fixedly connected between the bottom of the lifting column and the moving platform, the lifting and lowering of the lifting column is controlled by the hydraulic rod, and as the lifting and lowering of the lifting column is coordinated with the meshing of the transmission rack and the gear, the synchronous and unidirectional rotation process of the four bending arms can be controlled, thereby ensuring the stability of supporting the moving platform.

[0013] Preferably, a marking component is provided on the bottom surface of the mobile platform, and the marking component is used to leave a mark on the wall surface. A docking component is provided on the bottom surface of the mobile platform, and the docking component is used to adapt to the mark left by the marking component to locate the position of the mobile platform. In order to pursue progress, common construction has a process of synchronous construction of multiple inner walls, and the construction process device does not need to be fixed in place all the time, but only needs to find the anchor point first. After the first measurement, subsequent measurements can be performed in the middle of the construction and when the construction is about to be completed. The anchor point position of the device is marked by the marking component. After the first measurement is completed, the device can be moved on the wall surface driven by the electric wheel, and moved to the outside of another wall surface to be constructed for the first measurement. After the measurement, the position is also marked. When the thickness of other construction walls needs to be measured, the electric wheel drives the mobile platform to move to the anchor point position, and the mark left by the docking component is docked with the marking component to determine the anchor point position, so that the mobile platform can be quickly positioned. Through this setting, it is achieved that one device can control the thickness of plastering at the same time when multiple inner walls are under construction.

[0014] Preferably, the marking component includes an electric spray gun fixedly connected to the bottom of the mobile platform, the spraying end of the electric spray gun is tilted, the docking component includes a protective frame made of glass, the protective frame is located in the middle of the bottom surface of the mobile platform, and the camera is located on the inner side of the protective frame. When the anchor point is determined, the electric spray gun sprays paint toward the wall, and the paint uses erasable disposable paint. The spraying port of the electric spray gun is tilted toward the protective frame, so it can be sprayed directly at the position opposite to the protective frame during spraying. When positioning is required, the spraying position is observed by the camera, and the camera shoots at a wide angle. When the spraying position is moved to the center point of the camera position, the device moves into place. Through this arrangement, the functions of marking the anchor point and re-docking and positioning are realized.

[0015] Preferably, the marking component includes a hot-melt adhesive strip, a filling groove for placing the hot-melt adhesive strip is provided on the bottom surface of the movable platform, a protective cover is provided on the outer side of the filling groove, an electric squeezing roller for driving the hot-melt adhesive strip to move is installed in the movable platform, an electric heating wire for heating part of the hot-melt adhesive strip is provided on the inner side of the filling groove, and an arc-shaped restraining platform is provided in the filling groove, and an electric telescopic rod for driving the restraining platform to rise and fall is fixedly connected to one side of the restraining platform. Since the movement of the movable platform is multi-angle, after the movable platform moves to the anchor point position, it is also necessary to ensure that the orientation of the laser rangefinder is the original orientation. Through the setting of the hot-melt adhesive strip, before the device works, the protective cover is opened, the hot-melt adhesive strip is placed in the filling groove, and the protective cover is closed to close the filling groove, the protective cover will fit the hot-melt adhesive strip, and when the device anchor point is fixed and the first measurement is completed, the movable platform is first translated for a distance, the electric squeezing roller is started to rub the hot-melt adhesive strip, so that it moves in the direction of the heating wire, and part of the hot-melt adhesive strip moves to the restraining point. The electric telescopic rod is then extended to push the binding platform outward, allowing the hot-melt adhesive strip to fit the electric heating wire, thereby heating one side of the hot-melt adhesive strip. After heating for a period of time, the heating of the electric heating wire is stopped, and the length of the protective cover is less than the length of the filling groove, so that a small section of the hot-melt adhesive strip is exposed on the outside, and its position is just aligned with the binding platform. The binding platform continues to push the hot-melt adhesive strip outward, and the hot-melt adhesive strip is relatively soft. As the binding platform is pushed out, the hot-melt adhesive strip on the binding platform will be separated from the hot-melt adhesive strip in the filling groove. At the same time, the heated and separated hot-melt adhesive strip will push the electric heating wire open and hot-melt fit the wall. Since the mobile platform was translated before the hot-melt adhesive strip was fixed, the fixed position of the hot-melt adhesive strip here is the anchor point position. Since the binding platform is set in an arc shape, when the binding platform is docked with the docking component, there is only one direction in which docking can be performed. The docking position is observed by a camera, so that it can be ensured that after the mobile platform is docked with the hot-melt adhesive strip, the position and direction of the mobile platform remain in the original positioning state, thereby ensuring the accuracy of subsequent measurement data.

[0016] Preferably, a cutting wire for cutting the hot-melt adhesive strip is provided on one side of the restraining platform, and a rotatable power supply seat is provided on the bottom of the movable platform. The power supply seat is fixedly connected to the heating wire, and the power supply seat provides power to the heating wire and the cutting wire at the same time. In order to facilitate the cutting process of the hot-melt adhesive strip, when the restraining platform pushes the hot-melt adhesive strip outward, the hot-melt adhesive strip will contact the cutting wire, and the cutting wire can be energized to generate heat, thereby separating the hot-melt adhesive strip on the restraining platform from the hot-melt adhesive strip in the filling groove. At the same time, when pushing on the restraining platform, the power supply seat rotates outward, and a motor is fixedly connected to one side of the power supply seat to drive the power supply seat to rotate, so that the heating wire is away from the hot-melt adhesive strip, thereby facilitating the fitting of the hot-melt adhesive strip to the wall.

[0017] Preferably, the docking assembly includes an arc-shaped docking block, the restraining platform and the docking block have the same curvature, the surface of the docking block is provided with a groove which is the same as the surface of the restraining platform, the camera is arranged on one side of the docking block, and the camera is arranged at an angle. The inclined camera facilitates observation of the docking process between the hot-melt adhesive strip and the docking block, and the arc-shaped docking block and the arc-shaped hot-melt adhesive strip can fit perfectly to ensure that the moving platform is in its original position and direction after docking.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The thickness control device for interior wall plastering described in the present invention is provided with a laser rangefinder. Before plastering, the laser rangefinder is first fixed in a position facing the interior wall. Then, the laser rangefinder emits a laser to measure the distance from the device to the wall. The laser rangefinder is driven to rotate by servo motor 1 and servo motor 2. The laser rangefinder can be made to face each corner of the wall without moving its own position. A measurement program can be formulated to preset multiple points to measure the distance from the laser rangefinder to multiple points on the wall. Then, the plastering work is started. When the plastering is halfway done, the laser rangefinder is used to measure the distance from the laser rangefinder to the wall. Start measuring the distance from the device to the wall at this time. By measuring multiple points and comparing it with the distance from the device to the wall before plastering, the thickness of the plastering can be calculated. The operator can wear the terminal device to receive the measurement data of the laser rangefinder to know the thickness of the plastering. In the final stage, the laser rangefinder is used again to measure and obtain the thickness of the plastering at this time. By increasing or polishing, the thickness of the plastering can be controlled more accurately. Through this setting, the effect of accurately controlling the thickness of the interior wall plastering is achieved, and the whole process has a high degree of automation, fewer operating steps, and can be completed more easily.

[0020] 2. The thickness control device for interior wall plastering described in the present invention, after the anchor point is determined, first let the laser rangefinder face the wall, the position of the anchor point is generally selected on the horizontal midpoint plane of the wall, so that the rotation angle of the laser rangefinder to both sides of the wall is the same, which is convenient for adjustment; the direction of the laser rangefinder on the vertical plane is adjusted by servo motor 1, and the direction of the laser rangefinder on the horizontal plane is controlled by servo motor 2. The cooperation of the two can make the laser rangefinder face every corner of the wall, ensuring the accuracy of measurement, thereby assisting in the thickness control of the plastering.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 7As shown, a thickness control device for interior wall plastering according to an embodiment of the present invention comprises a laser rangefinder 3, a servo motor 1 6 and a servo motor 2 8 for adjusting the direction of the laser rangefinder 3 are arranged on the outside of the laser rangefinder 3, a moving platform 1 is arranged on the outside of the laser rangefinder 3, four electric wheels 5 for driving the moving platform 1 to move are arranged on the outside of the moving platform 1, two negative pressure holes 9 are opened on the top surface of the moving platform 1 and extend to the bottom, a negative pressure fan is arranged in the negative pressure hole 9, and a camera 15 for locating the position of the moving platform 1 is arranged at the bottom of the moving platform 1;

[0032] In a room surrounded by walls on all sides, it is impossible to measure the thickness of the plaster from the side of the inner wall. In addition, the wall is high, so the operator usually needs to operate on a pad. If the distance between the anchor point and the wall is constantly measured, the plastering period will be extended, affecting the efficiency of the plastering.

[0033] By setting the laser rangefinder 3, the laser rangefinder 3 is first fixed in a position facing the inner wall before plastering, and then the laser rangefinder 3 emits a laser to measure the distance from the device to the wall. The laser rangefinder 3 is driven to rotate by the servo motor 1 6 and the servo motor 2 8, so that the laser rangefinder 3 can make the laser emission end face every corner of the wall without moving its own position. A measurement program can be formulated, and multiple points can be preset to measure the distance from the laser rangefinder 3 to multiple points on the wall. Then the plastering work begins. When the plastering is halfway through, the laser rangefinder 3 starts to measure the distance from the device to the wall at this time. By measuring multiple points and comparing them with the distance from the device to the wall before plastering, the thickness of the plastering can be calculated. The operator can wear the terminal device to receive the measurement data of the laser rangefinder 3, so as to know the thickness of the plastering. In the final finishing stage, the laser rangefinder 3 is used again for measurement to obtain the plastering thickness at this time. By increasing or polishing, the thickness of the plastering can be controlled more accurately. After the laser rangefinder 3 rotates at an angle, it will record its own The angle of rotation, and the actual thickness increase of the wall is calculated according to the trigonometric function; the acquired data can also be used directly without correction, which is faster than the former, because the thickness of the plaster is generally 20 mm, and the deviation caused by the angle will not cause a large impact; in order to ensure that the anchor point fixed by the laser rangefinder 3 remains stationary, the laser rangefinder 3 is carried on the mobile platform 1, and the mobile platform 1 can control itself to move through the electric wheel 5, and after moving into place, the negative pressure fan is started to generate negative pressure at the bottom of the mobile platform 1, thereby adsorbing and fixing the mobile platform 1, so that the mobile platform 1 cannot move. In this way, after selecting the anchor point, you can first mark the anchor point, and use the camera 15 to observe the mark position, so that the mobile platform 1 and the laser rangefinder 3 can be fixed in place and cannot be easily moved. When it is necessary to plaster other inner walls, the mobile platform 1 is controlled by the drive of the electric wheel 5 to perform the transfer work. Through this setting, the effect of accurately controlling the thickness of the inner wall plastering is achieved, and the whole process has a high degree of automation, fewer operating steps, and can be completed relatively easily.

[0034] The laser emitting end of the laser rangefinder 3 is arranged horizontally, the output end of the servo motor 1 6 is fixedly connected to the outer side of the laser rangefinder 3, and the servo motor 1 6 is used to drive the laser rangefinder 3 to rotate on a vertical plane. A support frame 7 is fixedly connected to the outer side of the servo motor 1 6, and the top output end of the servo motor 2 8 is fixedly connected to the support frame 7, and the servo motor 2 8 is used to drive the laser rangefinder 3 to rotate on a horizontal plane;

[0035] During operation, after the anchor point is determined, first let the laser rangefinder 3 face the wall. The position of the anchor point is generally selected on the horizontal midpoint plane of the wall, so that the rotation angle of the laser rangefinder 3 to both sides of the wall is the same, which is convenient for adjustment; the direction of the laser rangefinder 3 on the vertical plane is adjusted by the servo motor 1 6, and the direction of the laser rangefinder 3 on the horizontal plane is controlled by the servo motor 2 8. The cooperation of the two can make the laser rangefinder 3 face every corner of the wall, ensuring the accuracy of the measurement, thereby assisting in the control of the thickness of the plastering.

[0036] A filling capsule 2 is fixedly connected to the outside of the mobile platform 1, the inside of the filling capsule 2 is hollow, the surface of the filling capsule 2 is made of wear-resistant material, a one-way valve 14 is fixedly connected to the bottom of the negative pressure hole 9, four bending arms 4 for connecting the electric wheels 5 and controlling the lifting of the mobile platform 1 are arranged on the top of the mobile platform 1, and a pressure relief solenoid valve 27 connected to the bottom surface is installed on the top surface of the mobile platform 1;

[0037] During work, the plastering process of the inner wall is generally when the house is in the process of decoration. At this time, the ground is full of decoration equipment, and the operator will also walk around. The device not only occupies a certain space, but is also easily damaged by collision. Through the setting of the filling capsule 2, the mobile platform 1 can be adsorbed by the negative pressure generated by the negative pressure fan, so the mobile platform 1 can be moved on the wall. Move the mobile platform 1 to the top of the wall and let the device hang upside down on the wall. During the movement, the bending arm 4 props up the entire mobile platform 1 so that the filling capsule 2 does not touch the wall. When the mobile platform 1 moves to the anchor point position, the bending arm 4 bends to make the filling capsule 2 fit the wall, increase the speed of the negative pressure fan, and thus increase the suction at the bottom of the mobile platform 1. The first part is hollow and deformable, so it can be sealed even on a rough cement surface. With the setting of the one-way valve 14, a closed space is formed between the mobile platform 1 and the wall. Even if the negative pressure fan is closed, since the one-way valve 14 can only flow in one direction, the mobile platform 1 will be adsorbed on the wall under the action of negative pressure. When the mobile platform 1 needs to move, the pressure relief solenoid valve 27 is opened, and the negative pressure fan is turned on at the same time to generate a certain suction force, so that the bending arm 4 drives the mobile platform 1 away from the wall, so that the mobile platform 1 can be moved. Through this setting, the device can be fixed on the top of the wall, which not only does not occupy the ground space, but also greatly reduces the problem of the position being changed or the equipment being damaged due to human influence after the device is fixed.

[0038] The top of the electric wheel 5 is installed at the end of the bending arm 4, and the top of the bending arm 4 is rotatably connected to the moving platform 1. The bending arm 4 is arranged in sections, and the bending arms 4 at two adjacent ends are rotatably connected, and a torsion spring is provided at the rotation connection. The top of the moving platform 1 is provided with a lifting column 10 for driving the bending arm 4 to rotate;

[0039] During operation, the bending arm 4 can be controlled to rotate by raising and lowering the lifting column 10. As the bending arm 4 rotates, the mobile platform 1 can be lifted up and away from the wall, or the bottom of the mobile platform 1 can be pressed against the wall. This is suitable for the movement and fixation processes of the mobile platform 1. The bending arm 4 is arranged in sections, and the bending between each section will accumulate elastic potential energy under the action of the torsion spring. In this way, it can be ensured that no matter how the bending arm 4 rotates, the bending arm 4 can bend adaptively, so that the electric wheel 5 is always pressed against the wall, and the electric wheel 5 can normally drive the mobile platform 1 to move.

[0040] Four transmission racks 11 are fixedly connected to the outer side of the lifting column 10, a gear 12 is fixedly connected to the top of the bending arm 4, the gear 12 is meshed with the transmission rack 11, both ends of the gear 12 are rotatably connected to the moving platform 1, and a hydraulic rod is fixedly connected between the bottom of the lifting column 10 and the moving platform 1;

[0041] During operation, the lifting and lowering of the lifting column 10 is controlled by the hydraulic rod. As the lifting and lowering of the lifting column 10 is carried out, the meshing of the transmission rack 11 and the gear 12 can control the synchronous and unidirectional rotation of the four bending arms 4, thereby ensuring the stability of the supporting mobile platform 1.

[0042] The bottom surface of the mobile platform 1 is provided with a marking component, and the marking component is used to leave a mark on the wall. The bottom surface of the mobile platform 1 is provided with a docking component, and the docking component is used to adapt to the mark left by the marking component, so as to locate the position of the mobile platform 1;

[0043] During operation, common construction involves simultaneous construction of multiple interior walls in order to pursue progress. During the construction process, the device does not need to be fixed in place all the time. It only needs to find the anchor point first and perform the first measurement. Then, measurements can be performed in the middle of the construction or when the construction is about to be completed. The anchor point position of the device is marked by the marking component. After the first measurement, the device can be moved on the wall surface driven by the electric wheel 5 and moved to the outside of another wall to be constructed for the first measurement. The position is also marked after the measurement. When the thickness of other construction walls needs to be measured, the electric wheel 5 drives the mobile platform 1 to move to the anchor point position, and the mark left by the marking component is docked by the docking component to determine the anchor point position, so as to quickly locate the mobile platform 1. Through this arrangement, one device can control the thickness of the plastering at the same time when constructing multiple interior walls.

[0044] The marking assembly includes an electric spray gun 25 fixedly connected to the bottom of the mobile platform 1, and the spray end of the electric spray gun 25 is arranged at an angle. The docking assembly includes a protective frame 26 made of glass, and the protective frame 26 is located in the middle of the bottom surface of the mobile platform 1, and the camera 15 is located inside the protective frame 26;

[0045] During operation, after the anchor point is determined, the electric spray gun 25 sprays paint toward the wall. The paint uses erasable disposable paint. The spray port of the electric spray gun 25 is tilted toward the protective frame 26, so it can be sprayed directly at the position opposite the protective frame 26. When positioning is required, the spraying position is observed through the camera 15, and the camera 15 takes a wide-angle shot. When the spraying position is moved to the center point of the camera position, the equipment moves into place. Through this setting, the functions of marking the anchor point and re-docking and positioning are realized.

[0046] The marking assembly includes a hot melt adhesive strip 17, a filling groove 21 for placing the hot melt adhesive strip 17 is provided on the bottom surface of the movable platform 1, a protective cover 13 is provided on the outer side of the filling groove 21, an electric squeezing roller 23 for driving the hot melt adhesive strip 17 to move is installed in the movable platform 1, an electric heating wire 19 for heating part of the hot melt adhesive strip 17 is provided on the inner side of the filling groove 21, and an arc-shaped restraining platform 20 is provided in the filling groove 21, and an electric telescopic rod 24 for driving the restraining platform 20 to rise and fall is fixedly connected to one side of the restraining platform 20;

[0047] During operation, since the movement of the mobile platform 1 is multi-angle, after the mobile platform 1 moves to the anchor point position, it is also necessary to ensure that the orientation of the laser rangefinder 3 is the original orientation. Through the setting of the hot-melt adhesive strip 17, before the device works, the protective cover 13 is opened, the hot-melt adhesive strip 17 is placed in the filling groove 21, and the protective cover 13 is closed to close the filling groove 21. The protective cover 13 will fit the hot-melt adhesive strip 17. When the device anchor point is fixed and the first measurement is completed, the mobile platform 1 is first translated for a distance, and the electric squeezing roller 23 is started to rub the hot-melt adhesive strip 17 to move it in the direction of the electric heating wire 19, so that part of the hot-melt adhesive strip 17 moves to the restraining platform 20, and then the electric telescopic rod 24 is extended to push the restraining platform 20 outward, so that the hot-melt adhesive strip 17 fits the electric heating wire 19, thereby heating one side of the hot-melt adhesive strip 17. After heating for a period of time, the heating of the electric heating wire 19 is stopped, and the length of the protective cover 13 is less than the filling wire 19. The length of the filling groove 21 allows a small section of the hot-melt adhesive strip 17 to be exposed on the outside, and its position is just aligned with the restraining platform 20. The restraining platform 20 continues to push the hot-melt adhesive strip 17 outward. The hot-melt adhesive strip 17 is relatively soft. As the restraining platform 20 is pushed out, the hot-melt adhesive strip 17 on the restraining platform 20 will be separated from the hot-melt adhesive strip 17 in the filling groove 21. At the same time, the heated and separated hot-melt adhesive strip 17 will push the electric heating wire 19 to be hot-melt-bonded to the wall. Because the movable platform 1 is translated before the hot-melt adhesive strip 17 is fixed, the fixed position of the hot-melt adhesive strip 17 here is the anchor point position. Since the restraining platform 20 is arranged in an arc shape, when the restraining platform 20 is docked with the docking component, there is only one direction in which docking can be performed. The docking position is observed by the camera 15. In this way, it can be ensured that after the movable platform 1 is docked with the hot-melt adhesive strip 17, the position and direction of the movable platform 1 remain in the original positioning state, thereby ensuring the accuracy of subsequent measurement data.

[0048] A cutting wire 22 for cutting the hot melt adhesive strip 17 is disposed on one side of the binding platform 20, and a rotatable power supply seat 18 is disposed at the bottom of the mobile platform 1. The power supply seat 18 is fixedly connected to the heating wire 19, and the power supply seat 18 provides power to the heating wire 19 and the cutting wire 22 at the same time;

[0049] During operation, in order to facilitate the cutting process of the hot-melt adhesive strip 17, when the binding platform 20 pushes the hot-melt adhesive strip 17 outward, the hot-melt adhesive strip 17 will contact the cutting wire 22, and the cutting wire 22 can be energized to generate heat, thereby separating the hot-melt adhesive strip 17 on the binding platform 20 from the hot-melt adhesive strip 17 in the filling groove 21. At the same time, when the binding platform 20 is pushed up, the power supply seat 18 rotates outward. A motor is fixed to one side of the power supply seat 18 to drive the power supply seat 18 to rotate, so that the heating wire 19 is away from the hot-melt adhesive strip 17, thereby facilitating the hot-melt adhesive strip 17 to fit the wall.

[0050] The docking assembly includes an arc-shaped docking block 16, the curvature of the restraining platform 20 and the docking block 16 are the same, the surface of the docking block 16 is provided with a groove that is the same as the surface of the restraining platform 20, and the camera 15 is arranged on one side of the docking block 16, and the camera 15 is arranged in an inclined manner;

[0051] During operation, the tilted camera 15 facilitates observation of the docking process between the hot melt adhesive strip 17 and the docking block 16. The arc-shaped docking block 16 and the arc-shaped hot melt adhesive strip 17 can fit perfectly, ensuring that the moving platform 1 is in the original position and direction after docking.

[0052] During operation, through the setting of the laser rangefinder 3, the laser rangefinder 3 is first fixed in a position facing the inner wall before plastering, and then the laser rangefinder 3 emits a laser to measure the distance from the device to the wall. The laser rangefinder 3 is driven to rotate by the servo motor 1 6 and the servo motor 2 8, so that the laser rangefinder 3 can make the laser emission end face every corner of the wall without moving its own position. A measurement program can be formulated, and multiple points can be preset to measure the distance from the laser rangefinder 3 to multiple points on the wall. Then the plastering work begins. When the plastering is halfway through, the laser rangefinder 3 starts to measure the distance from the device to the wall at this time. By measuring multiple points and comparing them with the distance from the device to the wall before plastering, the thickness of the plastering can be calculated. The operator can wear the terminal device to receive the measurement data of the laser rangefinder 3, so as to know the thickness of the plastering. In the final finishing stage, the laser rangefinder 3 is used again for measurement to obtain the plastering thickness at this time. By increasing or polishing, the thickness of the plastering can be controlled more accurately. After the laser rangefinder 3 rotates at an angle, it will record The angle of its own rotation, and the actual thickness increase of the wall is calculated according to the trigonometric function; the acquired data can also be used directly without correction, which is faster than the former, because the thickness of the plaster is generally 20 mm, and the deviation caused by the angle will not cause a large impact; in order to ensure that the anchor point fixed by the laser rangefinder 3 remains stationary, the laser rangefinder 3 is carried on the mobile platform 1, and the mobile platform 1 can control itself to move through the electric wheel 5, and after moving into place, the negative pressure fan is started to generate negative pressure at the bottom of the mobile platform 1, thereby adsorbing and fixing the mobile platform 1, so that the mobile platform 1 cannot move. In this way, after selecting the anchor point, you can first mark the anchor point, and use the camera 15 to observe the mark position, so that the mobile platform 1 and the laser rangefinder 3 can be fixed in place and cannot be easily moved. When it is necessary to plaster other inner walls, the mobile platform 1 is controlled by the drive of the electric wheel 5 to transfer. Through this setting, the effect of accurately controlling the thickness of the inner wall plastering is achieved, and the whole process has a high degree of automation, fewer operating steps, and can be completed relatively easily;

[0053] After the anchor point is determined, let the laser rangefinder 3 face the wall first. The position of the anchor point is generally selected on the horizontal midpoint of the wall, so that the rotation angle of the laser rangefinder 3 to both sides of the wall is the same, which is convenient for adjustment; the direction of the laser rangefinder 3 on the vertical plane is adjusted by the servo motor 1 6, and the direction of the laser rangefinder 3 on the horizontal plane is controlled by the servo motor 2 8. The cooperation of the two can make the laser rangefinder 3 face every corner of the wall, ensuring the accuracy of the measurement, thereby assisting the control of the thickness of the plastering;

[0054] The plastering process of the inner wall is generally when the house is in the process of decoration. At this time, the ground is full of decoration equipment, and the operator will also walk around. The device not only occupies a certain space, but is also easily damaged by collision. Through the setting of the filling capsule 2, the mobile platform 1 can be adsorbed by the negative pressure generated by the negative pressure fan, so the mobile platform 1 can be moved on the wall. The mobile platform 1 is moved to the top of the wall, and the device is hung upside down on the wall. During the movement, the bending arm 4 props up the entire mobile platform 1 so that the filling capsule 2 does not touch the wall. When the mobile platform 1 moves to the anchor point position, the bending arm 4 bends to make the filling capsule 2 fit the wall, increase the speed of the negative pressure fan, and thus increase the suction at the bottom of the mobile platform 1. The movable platform 1 is flexible and can be deformed, so it can be sealed even on a rough cement surface. With the setting of the one-way valve 14, a closed space is formed between the movable platform 1 and the wall surface. Even if the negative pressure fan is closed, since the one-way valve 14 can only flow in one direction, the movable platform 1 will be adsorbed on the wall surface under the action of negative pressure. When the movable platform 1 needs to move, the pressure relief solenoid valve 27 is opened, and the negative pressure fan is opened at the same time to generate a certain suction force, so that the bending arm 4 drives the movable platform 1 away from the wall surface, so that the movable platform 1 can be moved. Through this setting, the device can be fixed on the top of the wall, which not only does not occupy the ground space, but also greatly reduces the problem of the position being changed or the equipment being damaged due to human influence after the device is fixed.

[0055] The bending arm 4 can be controlled to rotate by lifting and lowering the lifting column 10. As the bending arm 4 rotates, the mobile platform 1 can be lifted up away from the wall, or the bottom of the mobile platform 1 can be pressed against the wall, which is suitable for the moving process and the fixing process of the mobile platform 1. The bending arm 4 is arranged in sections, and the bending between each section will accumulate elastic potential energy under the action of the torsion spring. In this way, it can be ensured that no matter how the bending arm 4 rotates, the bending arm 4 can bend adaptively, so that the electric wheel 5 is always pressed against the wall, so that the electric wheel 5 can normally drive the mobile platform 1 to move;

[0056] The lifting column 10 is controlled by a hydraulic rod. As the lifting column 10 is lifted and lowered, the four bending arms 4 can be controlled to rotate synchronously and in the same direction in coordination with the meshing of the transmission rack 11 and the gear 12, thereby ensuring the stability of the supporting mobile platform 1.

[0057] In order to pursue progress, common construction has a process of simultaneous construction of multiple inner walls. During the construction process, the device does not need to be fixed in place all the time. It only needs to find the anchor point first, and after the first measurement, it can be measured again in the middle of the construction and when the construction is about to be completed. The anchor point position of the device is marked by the marking component. After the first measurement, the device can be moved on the wall surface driven by the electric wheel 5 and moved to the outside of another wall surface to be constructed for the first measurement. The position is also marked after the measurement. When the thickness of other construction walls needs to be measured, the electric wheel 5 drives the mobile platform 1 to move to the anchor point position, and the mark left by the docking component is docked with the marking component to determine the anchor point position, so as to quickly locate the mobile platform 1. Through this setting, one device can control the thickness of plastering at the same time when constructing multiple inner walls;

[0058] When the anchor point is determined, the electric spray gun 25 sprays paint toward the wall. The paint uses erasable disposable paint. The spray port of the electric spray gun 25 is tilted toward the protective frame 26, so it can be sprayed directly at the position opposite to the protective frame 26 during spraying. When positioning is required, the spraying position is observed through the camera 15, and the camera 15 shoots at a wide angle. When the spraying position is moved to the center point of the camera position, the device moves into place. Through this setting, the functions of marking the anchor point and re-docking and positioning are realized;

[0059] Since the movement of the mobile platform 1 is multi-angle, after the mobile platform 1 moves to the anchor point position, it is also necessary to ensure that the orientation of the laser rangefinder 3 is the original orientation. Through the setting of the hot-melt adhesive strip 17, before the device works, the protective cover 13 is opened, the hot-melt adhesive strip 17 is placed in the filling groove 21, and the protective cover 13 is closed to close the filling groove 21. The protective cover 13 will fit the hot-melt adhesive strip 17. When the device anchor point is fixed and the first measurement is completed, the mobile platform 1 is first translated for a distance, and the electric squeezing roller 23 is started to rub the hot-melt adhesive strip 17 to move it toward the direction of the electric heating wire 19, so that part of the hot-melt adhesive strip 17 moves to the restraining platform 20, and then the electric telescopic rod 24 is extended to push the restraining platform 20 outward, so that the hot-melt adhesive strip 17 fits the electric heating wire 19, thereby heating one side of the hot-melt adhesive strip 17. After heating for a period of time, the heating of the electric heating wire 19 is stopped, and the length of the protective cover 13 is less than the filling groove. The length of 21 makes a small section of hot-melt adhesive strip 17 exposed outside, and its position is just aligned with the binding platform 20. The binding platform 20 continues to push the hot-melt adhesive strip 17 outward. The hot-melt adhesive strip 17 is relatively soft. As the binding platform 20 is pushed out, the hot-melt adhesive strip 17 on the binding platform 20 will be separated from the hot-melt adhesive strip 17 in the filling groove 21. At the same time, the hot-melt adhesive strip 17 after heating and separation will push the electric heating wire 19 to hot-melt fit with the wall. Because the mobile platform 1 is translated before the hot-melt adhesive strip 17 is fixed, the fixed position of the hot-melt adhesive strip 17 here is the anchor point position. Since the binding platform 20 is set in an arc shape, when the binding platform 20 is docked with the docking component, there is only one direction in which docking can be performed. The docking position is observed by the camera 15. In this way, it can be ensured that the position and direction of the mobile platform 1 are kept in the original positioning state after docking with the hot-melt adhesive strip 17, thereby ensuring the accuracy of subsequent measurement data.

[0060] In order to facilitate the process of splitting the hot-melt adhesive strip 17, when the binding platform 20 pushes the hot-melt adhesive strip 17 outward, the hot-melt adhesive strip 17 will contact the cutting wire 22, and the cutting wire 22 can be powered to generate heat, thereby splitting the hot-melt adhesive strip 17 on the binding platform 20 and the hot-melt adhesive strip 17 in the filling groove 21. At the same time, when the binding platform 20 is pushed up, the power supply seat 18 rotates outward, and a motor is fixedly connected to one side of the power supply seat 18 to drive the power supply seat 18 to rotate, so that the heating wire 19 is away from the hot-melt adhesive strip 17, thereby facilitating the hot-melt adhesive strip 17 to fit the wall surface;

[0061] The tilted camera 15 facilitates observation of the docking process between the hot melt adhesive strip 17 and the docking block 16. The arc-shaped docking block 16 and the arc-shaped hot melt adhesive strip 17 can fit perfectly, ensuring that the moving platform 1 is in the original position and direction after docking.
