A plastering apparatus 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 8.
As shown in fig. 1, a plastering apparatus 100 comprises: a plastering assembly 30, a distance measuring assembly 2, a sensor assembly 3 and a control device (not shown in the figure). Through the cooperation between each structure, can realize the high accuracy operation of plastering unit 100, improve the quality of plastering, still guarantee work efficiency simultaneously.
Specifically, the method comprises the following steps: as shown in fig. 1-4, the plastering assembly 30 can plaster the wall 10 previously coated with the coating, the plastering assembly 30 includes a troweling bracket 1 and a plastering member installed on the troweling bracket 1, the plastering member can be a troweling board (not shown in the figure) arranged on the troweling bracket 1, the troweling bracket 1 provides an installation foundation for the troweling board, and the troweling board can be more stable when in use, the troweling board is suitable for plastering the wall 10, and the troweling board can be installed on the troweling bracket 1 to perform efficient plastering operation on the wall 10, thereby improving the working efficiency of plastering. The plastering member can also be a plastering barrel installed on the plastering support 1. The coating can be a mortar coating or a putty coating.
As shown in fig. 1 to 4, the ranging assembly 2 includes: the first distance measuring mechanism 21 and the second distance measuring mechanism 22 are respectively arranged at the left side and the right side of the floating support 1, and the first distance measuring mechanism 21 and the second distance measuring mechanism 22 are respectively arranged at the left side and the right side of the floating support 1. From this through first range unit 21 and second range unit 22 can detect the distance between the left and right sides of floating support 1 and the wall 10 respectively, and then can detect whether the floating plate is parallel with wall 10.
Specifically, the first distance measuring mechanism 21 and the second distance measuring mechanism 22 are installed on the left and right sides of the troweling bracket 1, wherein the left and right directions are, for example, the left and right directions in fig. 3, while the first distance measuring mechanism 21 and the second distance measuring mechanism 22 are both disposed toward the wall surface 10 to be plastered, for example, the front and rear directions in fig. 3.
Further, first range finding mechanism 21 includes first range finding pole 211, and second range finding mechanism 22 includes the second range finding pole, and first range finding pole 211 and the second range finding pole homoenergetic pierce through the coating surface to end at the benchmark piece 20 of wall 10.
The datum part 20 may be a mortar cake, which is a plate protruding from the wall surface and constructed by a worker at the wall root (position of the skirting line) with mortar, and is generally square. Because the mortar is constructed manually, the surface flatness of the mortar cakes is very high, the two mortar cakes construct an ideal standard wall surface 10, the mortar is sprayed on the wall surface 10 after the mortar cakes are completely hardened, the mortar cakes can be covered by the mortar after the mortar is sprayed, and the following example mainly takes a reference part as the mortar cakes. The connecting line of the two mortar cakes is generally vertical to the plastering direction, but the length of a part of the wall surface 10 to be plastered is possibly less than that of a plastering plate, so that the connecting line between the two mortar cakes is inclined to the plastering direction, and the plastering support 1 is rotatable, so that the plastering support 1 can drive the whole distance measuring assembly 2 to rotate to the direction of the connecting line between the two mortar cakes, and the left and right distance measuring mechanisms extend out to puncture mortar and abut against the mortar cakes so as to perform subsequent leveling operation.
The datum part 20 can also be a screed perpendicular to the plastering direction, and the screed is also laid at the position of the wall root by manual work. Because the ash cake is less relatively along the length of perpendicular to the direction of floating, first range unit 21 and second range unit 22 are not necessarily can the butt go on the ash cake, and the length of screed is far greater than the ash cake, can reduce the requirement of plastering equipment location accuracy, can let range unit butt go on the screed all the time.
The reference member 20 may also be a beam located above the wall surface, and for a wall frame cast by an aluminum mold, the beam above the wall surface has good surface flatness and can also be used as a reference surface.
Therefore, according to the plastering apparatus 100 of the embodiment of the invention, the first distance measuring rod 211 is installed in the first distance measuring mechanism 21, and the first distance measuring rod 211 can pass through mortar to make direct contact with the reference member 20 after the mortar passes; accordingly, a second distance measuring rod is mounted in the second distance measuring mechanism 22, and the second distance measuring rod can pass through the mortar to be in direct contact with the mortar-backed reference member 20. Through the reference member 20 direct contact behind first range finding pole 211 and the wall 10 mortar, the second range finding pole carries out direct contact with the reference member 20 behind the wall 10 mortar, can make the numerical value that first range finding mechanism 21 and second range finding mechanism 22 surveyed more accurate, has guaranteed the precision of plastering unit 100's work.
As shown in fig. 2 and 5, the sensor assembly 3 includes: the first distance measuring sensor 31 and the second distance measuring sensor 32, the first distance measuring sensor 31 and the second distance measuring sensor 32 are respectively suitable for measuring the extending distance of the first distance measuring rod 211 and the second distance measuring rod so as to obtain a first distance value and a second distance value between the floating plate and the reference member 20.
Specifically, as shown in fig. 2 and 5, the first distance measuring sensor 31 may measure the extending distance of the first distance measuring rod 211, so as to obtain the distance between the first distance measuring mechanism 21 and the reference member 20, such as the first distance value D1 in fig. 3; accordingly, the second distance measuring sensor 32 can measure the extending distance of the second distance measuring rod, so that the distance between the second distance measuring mechanism 22 and the reference member 20 can be obtained, for example, the second distance value D2 in fig. 3, and further, the positional relationship between the plastering device 100 and the wall surface 10 can be accurately adjusted through the values of D1 and D2, thereby ensuring the plastering effect of the plastering device 100 during operation.
Further, as shown in fig. 3 and 4, the control device (not shown) is adapted to obtain an angle between the trowel and the reference member 20 according to the first distance value and the second distance value, so as to adjust the trowel to be parallel to the reference member 20.
Specifically, for example, as shown in fig. 3, the plastering device 100 can measure the distance D1 between the plastering plate and the reference member 20 by the first distance measuring mechanism 21, measure the distance D2 between the plastering plate and the reference member 20 by the second distance measuring mechanism 22, measure whether the plastering plate is parallel to the wall surface 10 by the values of D1 and D2, and control the plastering device 100 to adjust by the control device, so that the plastering device 100 is parallel to the wall surface 10, thereby improving the plastering accuracy of the plastering plate and ensuring the plastering effect of the plastering device 100.
According to the plastering device 100 of the embodiment of the invention, the distance between the first distance measuring rod 211 and the reference member 20, namely a first distance value, can be measured by the first distance measuring sensor 31 in the distance measuring assembly 2, the distance between the second distance measuring rod and the reference member 20, namely a second distance value, can be measured by the second distance measuring sensor 32 in the distance measuring assembly 2, and whether the plastering device 100 is parallel to the reference member 20 can be detected by the first distance value and the second distance value. And furthermore, the plastering device 100 can be adjusted through the control device, so that the plastering device 100 is parallel to the reference member 20, thereby improving the working accuracy of the plastering member during plastering operation and improving the plastering quality.
Wherein, through the range finding subassembly 2 that sets up, and first range finding pole 211 can pierce the mortar and contact with reference member 20 in first range finding mechanism 21, second range finding pole can pierce the mortar and contact with reference member 20 in the second range finding mechanism 22, only need beat reference member 20 on wall 10 from this, can contact through first range finding pole 211 and reference member 20 and measure first interval value, second range finding pole and reference member 20 contact the second interval value that measures, and then learn the angle of plastering board and wall 10, thereby can realize plastering of plastering unit 100 to wall 10 through adjusting the angle of plastering board to being parallel with reference member 20, and need not set up the bar planting that the height is greater than reference member 20 along the direction of height at wall 10, work efficiency has been promoted from this.
After the plastering member is adjusted to be parallel to the reference member 20, the first distance measuring sensor 31 measures the extending distance of the first distance measuring bar 211, or the second distance measuring sensor 32 measures the extending distance of the second distance measuring bar, or the first distance measuring sensor 31 and the second distance measuring sensor 32 measure the extending distance of the first distance measuring bar 211 and the second distance measuring bar, respectively, to obtain a fourth distance value between the plastering assembly 30 and the reference member 20. The control device controls the plastering assembly 30 to move towards the wall surface according to the fourth distance value, the plastering thickness and the height of the reference member 20 protruding out of the wall surface 10, so as to carry out the plastering treatment on the wall surface 10. The troweling thickness and the height of the reference member 20 protruding from the wall surface 10 (hereinafter, the height of the reference member 20) are preset values. In some cases, the troweled thickness is higher than the surface of the reference member 20, for example, when a mortar cake or a transverse screed is used as the reference member 20, it is necessary to move the wall surface 10 by a fourth distance value (troweled thickness-reference member height) to reach the preset troweled thickness. In other cases, for example, when the beam is used as the reference member, the trowel thickness is lower than the surface of the reference member 20, and then the wall surface 10 needs to be moved by a fourth distance value + (height of the reference member-trowel thickness) to reach the preset trowel thickness.
