Description

Technical Field

[0001] The present invention relates to the technical field of house construction, and more particularly to a plastering robot for house construction. Background Art

[0002] Plastering is a decorative project that applies mortar to buildings. The plastering mortar is applied to the surface of the base material, protecting the base layer and enhancing its aesthetics. It protects the walls of buildings from erosion by wind, rain, and snow, increases the weathering resistance and thermal insulation capabilities of the walls of buildings, improves the durability of the walls, and enhances living comfort. Currently, common plastering robots primarily perform bottom-up construction operations, relying on manual labor to push the robot left or right to the construction area. During construction, the plastering mortar is directly delivered to the inclined plasterboard at a balanced flow rate. The plasterboard then squeezes the plastering mortar onto the base material to form a plaster layer. Due to the continuous feeding of the plastering mortar, the angle of the plasterboard cannot be adjusted in time when construction reaches the area near the top of the wall, resulting in less mortar at the top of the wall and more mortar at the bottom, resulting in uneven plastering.

[0024] like Figure 1-2 As shown, the present invention provides a plastering robot for house construction, comprising:

[0025] A base 1 having universal wheels 2;

[0026] A lifting unit, comprising a stand, a lifting structure, and a first power structure, wherein the stand is fixedly mounted in front of the base 1, the lifting structure is movably mounted on the stand, and the first power structure drives the lifting structure to reach different heights;

[0027] A longitudinal moving unit, comprising a longitudinal frame 6, a longitudinal moving structure, and a second power structure, wherein the longitudinal frame 6 is fixedly mounted in front of the lifting structure, the longitudinal moving structure is movably mounted in front of the longitudinal frame 6, and the second power structure drives the longitudinal moving structure to different longitudinal positions;

[0028] An angle adjustment unit, comprising a fixed plate 9, a plastering plate 10, an angle adjustment structure, and a third power structure. The fixed plate 9 is fixedly mounted in front of the longitudinal movable structure. The plastering plate 10 is movably mounted in front of the fixed plate 9 via the angle adjustment structure. The third power structure drives the angle adjustment structure to adjust the angle between the plastering plate 10 and the construction surface in front.

[0029] The transverse moving unit includes a feeding pump, a storage box 13, a transverse moving structure, a fourth power structure, and a fifth power structure. The storage box 13 is installed on the fixed plate 9 through the transverse moving structure. The feed port of the storage box 13 is located at the rear and is connected with the feeding pump through a flexible pipe. The discharge port of the storage box 13 is located at the front. The fourth power structure drives the storage box 13 through the transverse moving structure to make the discharge port move laterally backward at the position above the plastering board 10. The fifth power structure drives the storage box 13 to move vertically downward at the position above the fixed plate 9 through the transverse moving structure. The height of the storage box 13 is set to: when the storage box 13 touches the top surface of the fixed plate 9, the top surface of the storage box 13 is not higher than the top surface of the vertically arranged plastering board 10.

[0030] In the above technical solution, the base 1 forms an installation surface for installing various components, and its top universal wheel 2 can drag the base 1 to move and realize single-point locking positioning. The vertical frame of the lifting unit is a fixed structure, which is installed on the base 1 and plays a guiding role. The lifting structure can be a guide pulley assembly, a sprocket lifting assembly, etc. When a certain section is constructed, the plaster board 10 is lifted by the lifting structure for construction. The first motor structure can provide power for a rotating motor, etc. The longitudinal frame 6 of the longitudinal moving unit is installed on the lifting structure. As the lifting structure moves up and down, the longitudinal moving structure can be a guide pulley, a pulley assembly, etc., which moves longitudinally relative to the longitudinal frame 6. After the overall construction of a certain section is completed, it is moved to the next stage for construction through the longitudinal moving structure. The second power structure can provide power for a rotating motor, etc. For example, the longitudinal length of the fixed frame is less than 1 / 2 of the longitudinal length of the movable frame 7, so that the base 1 is located at the same position and at least two sections can be constructed, avoiding manual multiple movements of the present invention.

[0031] The fixed plate 9 of the angle adjustment unit is installed on the longitudinal moving structure. As the longitudinal moving structure moves longitudinally, the fixed plate 9 is used to install the plastering plate 10, the angle adjustment structure, the third power structure, the storage box 12, the fifth power structure, etc. The fixed plate 9 is parallel to the longitudinal frame 6 and the angle cannot be adjusted. The plastering plate 10 can adjust the angle relative to the fixed plate 9. The angle adjustment structure can be a ball seat, a mechanical arm, etc. During construction, the plastering plate 10 is tilted and the upper falling space is larger than the lower plastering space. When the construction is near the top of the wall, the plastering plate 10 is set parallel to the wall. The third power structure can provide power for a telescopic oil cylinder, a telescopic motor, etc. The storage of the horizontal moving unit The material box 13 is fed by a feeding pump and discharged through the discharge port. The material storage box 13 has a working position and a retreat position. The working position is directly above the plastering plate 10, so that the mortar at the discharge port enters the blanking space and plastering space below. The retreat position is directly above the fixed plate 9. At this time, the discharge port is closed, and the plastering plate 10 is against the top of the wall for top construction. The horizontal moving structure can be a guide pulley, a telescopic rod, etc. The fourth power structure enables the material storage box 13 to retreat horizontally. The fourth power structure can provide power for a rotating motor, a telescopic motor, etc. The fifth power structure drives the material storage box 13 to retreat vertically. The fifth power structure can provide power for a telescopic oil cylinder, a telescopic motor, etc.

[0032] When the present invention is used, the lower edge of the plastering board 10 contacts the wall surface. When the plastering board 10 is working, the storage box 13 sprays mortar between the plastering board 10 and the wall surface, that is, the mortar is evenly coated on the wall surface by movement. The amount of mortar and the flatness of the wall surface will affect the contact force between the wall surface and the plastering board 10. The construction can be carried out in sections along the extension direction (longitudinal) of the wall surface, reducing the manual push of the manipulator to move back and forth. When performing section construction, the position of the base 1 is determined, the universal wheel 2 is locked, the second power structure drives the longitudinal moving structure to reach the construction section, the third power structure drives the angle adjustment structure to tilt the plastering board 10 (the reserved space is larger at the top and smaller at the bottom), and the fourth power structure and the fifth power structure drive the lateral moving structure to make the storage box 13 be in the working position, that is, the plastering board 10 is installed. Directly above the plaster board 10, the mortar pumped by the feeding pump enters the blanking space and plastering space below from the discharge port, the feeding pump and the discharge port are started, and the mortar pumped by the feeding pump is evenly distributed above the plastering board 10. The first power structure drives the lifting structure to perform plastering construction from bottom to top until the storage box 13 reaches the top of the wall. The fourth power structure and the fifth power structure drive the transverse moving structure to make the storage box 13 in the retracted position, that is, directly above the fixed plate 9. The third power structure drives the angle adjustment structure to set the plastering board 10 parallel to the wall surface. The plastering board 10 continues to move upward, thereby flattening the mortar near the top of the wall, and performing plastering construction on the remaining wall surface on the top, completing this stage of construction. The second power structure drives the longitudinal moving structure to reach the next construction section, and repeats the above construction process.

[0033] The base 1 of the present invention can install various components and move to the construction area. It realizes vertical plastering through the lifting unit, longitudinal multi-segment plastering through the longitudinal moving unit, adjusts the angle between the plastering board 10 and the wall through the angle adjusting unit, and realizes the yielding plastering construction of the storage box 13 through the transverse moving unit, effectively improving the smoothness of plastering and the bonding force with the wall, making the plastering of the entire wall uniform, and improving the quality of plastering construction.

The first power structure drives one of the lifting lead screws 4 to rotate, and the pair of lifting lead screws 4 are belt-driven, and the I-shaped lifting block 5 rises or falls to reach different heights.

[0035] In the above technical solution, a pair of lifting lead screws 4 are respectively arranged inside a pair of columns 3 and are connected by bearings to realize the rotation of the lifting lead screws 4 relative to the columns 3. The first power structure can be arranged at the bottom of the columns 3 to drive one of the lifting lead screws 4 to rotate. By means of belt drive, the pair of lifting lead screws 4 are driven to rotate. A pair of lifting lead screw nuts of different heights are arranged on the lifting lead screws 4. The two pairs of lifting lead screw nuts connect the four vertices of the I-shaped lifting block 5 to realize the steady lifting and lowering of the I-shaped lifting block 5.

[0036] In another technical solution, the longitudinal moving structure includes a moving frame 7, a rack 8, and a driving gear. The top and bottom surfaces of the moving frame 7 are respectively provided with longitudinal sliding grooves. The longitudinal frame 6 is respectively provided with sliders that can slide in the longitudinal sliding grooves. The rear surface of the moving frame 7 is provided with the rack 8.

[0037] In the above technical solution, the cross-section of the moving frame 7 is a U-shaped structure.

[0038] It should be noted that there is an error in the English translation of the part "带动齿条8的纵向移动,即带动纵向架6的纵向移动" in item . The corrected translation is "带动 the longitudinal movement of the rack 8, that is,带动 the longitudinal movement of the longitudinal frame 6". The correct and complete translation of item is: In the above technical solution, the cross-section of the moving frame 7 is a U-shaped structure. The rack 8 is installed in the middle and meshes with the driving gear of the longitudinal frame 6. The second power structure drives the driving gear to rotate,带动 the longitudinal movement of the rack 8, that is,带动 the longitudinal movement of the longitudinal frame 6. The top and bottom surfaces of the moving frame 7 are used to install longitudinal sliding grooves, which play a guiding role for the sliders of the longitudinal frame 6, making the longitudinal sliding process smooth.In another technical solution, the angle adjustment structure includes an upper connecting rod, a lower connecting rod, and a rangefinder. The upper connecting rod and the lower connecting rod are located at a height of the vertical center line of the plastering plate 10. The front end of the upper connecting rod is hinged to the plastering plate 10, and the rear end of the upper connecting rod is hinged to the third power structure. The front end of the lower connecting rod is hinged to the plastering plate 10, and the rear end of the lower connecting rod is fixedly connected to the fixed plate 9. The rangefinder is embedded in the front surface of the plastering plate 10, and the third power structure drives the upper connecting rod to swing to adjust the angle between the plastering plate 10 and the construction surface.

[0039] In the above technical solution, both ends of the upper connecting rod are hinged, the front end of the lower connecting rod is hinged and the rear end is fixed. There is no restriction on the form and principle of the rangefinder. For example, a laser rangefinder emits a laser to the wall and measures the time when it returns to calculate the distance. The controller adjusts the telescopic length of the third power structure and the hinge point angle of the upper connecting rod and the lower connecting rod according to the distance control, and adjusts the angle between the plastering plate 10 and the wall. When the distance of the upper connecting rod is greater than the distance of the lower connecting rod, it is convenient for blanking. When the distance of the upper connecting rod is equal to the distance of the lower connecting rod, it is convenient for construction on the top of the wall. The third power structure pushes the upper connecting rod to swing through its telescopic part, such as the telescopic rod, so that the plastering plate 10 changes between a parallel position and an inclined position, thereby realizing active and flexible control of the plastering plate 10 and improving the construction quality of the plastering process.

[0040] In another technical solution, the lateral movement structure includes a pair of telescopic screws 11, a pair of telescopic screw nuts, a gear transmission assembly, and a storage box 12. The pair of telescopic screws 11 are arranged in parallel in the horizontal direction, and the front ends of the pair of telescopic screws 11 are fixed to the rear surface of the storage box 13. The pair of telescopic screw nuts are each provided with a telescopic screw 11. The gear transmission assembly includes a pair of first bevel gears and a pair of second bevel gears. A first bevel gear is fixed to the outside of a telescopic screw nut, and the first bevel gear is meshed with the second bevel gear. The fourth power structure drives the axle of a second bevel gear to rotate, and the axle belt of a pair of second bevel gears is driven, and the storage box 13 moves laterally to different positions.

Since the telescopic screw nut is installed inside the storage box 12 through a bearing, only rotation occurs and no displacement occurs, that is, the telescopic screw 11 moves laterally, and the fifth power structure drives the storage box 12 to move up and down, thereby driving the components inside the storage box 12 and the storage box 13 connected thereto to move up and down, so that the storage box 13 moves from above the plastering board 10 to above the fixed plate 9.

When the first touch-pressure block 14 is subjected to external force, the first touch-pressure spring is compressed until the cross rod part of the first touch-pressure block 14 touches the first touch-pressure switch, and the fourth power structure is started. When the second touch-pressure block is no longer subjected to external force, the elastic force of the second touch-pressure spring reaches the cross rod part of the second touch-pressure block when it touches the second touch-pressure switch, and the fifth power structure is started.

[0044] When the material storage box 13 is retracted near the top wall, the first contact pressure spring is compressed to the top of the vertical rod of the first contact pressure block 14 and retracts into the material storage box 13, and the cross bar of the first contact pressure block 14 presses the first contact pressure switch downward to start the fourth contact pressure block 14. That is, when the storage box 13 touches the top surface of the fixed plate 9, the second contact pressure spring is converted from being compressed again from being naturally extended, and the bottom end of the vertical rod portion of the second contact pressure block is retracted into the storage box 13 again, and the second contact pressure switch is disconnected.
