Now, the plastering process provided in the embodiments of the present application will be described.
The plastering process comprises the step of enabling the scraper to generate ultrasonic vibration in the process of plastering the plaster.
Compared with the prior art, the plastering process has the advantages that ultrasonic vibration is generated by the scraper, so that the plastering material and ultrasonic waves resonate in the process of plastering the plastering material by the scraper, gaps in the plastering material and gaps between the plastering material and a target wall are eliminated, the compactness of the plastering material is improved, and the hollowing phenomenon in the plastering material after the plastering material is solidified is prevented; meanwhile, under the vibration effect of ultrasonic waves, the liquidity of the ash is enhanced, the resistance of the scraper when the scraper is used for scraping the ash is reduced, and the scraper is convenient for scraping the ash.
Specifically, in the present application, before the scraper is used to level the mortar, a leveling datum plane and a mortar spraying need to be determined on the target wall surface, and the scraper and the target wall surface need to be positioned.
In determining the screeding reference surface, first, the plastering thickness on the target wall surface needs to be determined. And then, manufacturing a plurality of mortar cakes on the target wall surface according to the plastering thickness, and enabling the outer surfaces of the plurality of mortar cakes to be positioned on the same plane for ensuring the flatness and the verticality of the mortar after plastering. Wherein, the plane of the outer side surface of the ash cake is a strickle reference plane.
Specifically, the number of the ash cakes is two, the two ash cakes are both positioned at the bottom of the target wall surface and at the same horizontal position, and the two ash cakes are spaced from the ground;
and then, after the ash cakes are manufactured, the ash cakes are naturally dried, and then the guiding ruler is placed at the bottom of the target wall surface and is abutted against the outer surface of the connected ash cakes.
And in the process of spraying the lime, coating the lime on the target wall surface until the spraying thickness of the lime is close to the thickness required by the leveling reference surface, and waiting for the next leveling.
Specifically, the ash is coated on a target wall surface by a spraying robot.
The scraper blade is connected on plastering robot, by plastering robot drive to make the scraper blade can remove at horizontal direction and vertical direction, thereby make the scraper blade can trowel the lime-aggregate at different positions on the target wall, and trowel the lime-aggregate on the target wall of difference, be equipped with setting element and control on the plastering robot.
In the process of positioning the scraper and the target wall surface, the positioning piece is used for acquiring the distance information between the plastering robot and the target wall surface, the control piece is used for receiving the distance information acquired by the positioning piece and controlling the plastering robot to move according to the distance information to adjust the position of the plastering robot relative to the target wall surface, and the scraper is always in contact with the plaster, so that the plastering precision of the scraper to the plaster is ensured.
Specifically, the setting element is the resilience distancer, and when resilience distancer and scale butt, at this moment, the control acquires the interval numerical value between plastering robot and the target wall this moment to subtract the thickness of scale with this numerical value, with the reference plane of strickleing off of confirming plastering robot, thereby the control scraper blade is in strickleing off the interior vertical direction up and down movement of reference plane, with the plastering material trowelling.
At the in-process of leveling the lime material, produce ultrasonic vibration through ultrasonic wave generating device to drive the scraper blade and produce ultrasonic vibration, the scraper blade is at the in-process of leveling the lime material, and the scraper blade drives the lime material and produces the ultrasonic wave and produce resonance, makes the inside gap of lime material and with the target wall between the clearance eliminated, improved the compactness of lime material and with lime material target wall piece adsorption effect, thereby prevent that the inside hollowing phenomenon from appearing after the lime material solidification. Meanwhile, the returned materials resonate with the ultrasonic waves, the liquidity of the ash materials is enhanced, the resistance of the scraper blade when the scraper blade scrapes the ash materials is reduced, the scraper blade is convenient for scraping the ash materials protruding out of the scraping reference surface to the position where the ash materials are sunken in the scraping reference surface, the scraper blade is convenient for leveling the ash materials, and the flatness and the verticality of the scraping reference surface are guaranteed after the ash materials are scraped.
In one embodiment of the application, ultrasonic vibration is generated by the scraper in the process of leveling the ash, the thickness value of the ash where the scraper is located at present is obtained, and when the thickness value is lower than a preset value, the vibration intensity of the scraper is adjusted according to the thickness value.
The consistency of the putty is used to indicate the degree of softness. Wherein, the high consistency value indicates that the ash is soft and has good fluidity; a low consistency number indicates a stiff ash with poor flow properties. When the consistency value of the ash is 10, the ash is in an ideal state, and the consistency value of the ash is not lower than 6.
The consistency of the ash is related to various factors, such as the proportion of various raw materials of the ash, the storage time and the environment. Wherein the ash consistency value becomes lower and lower with the passage of time. If the ash is in a humid environment, its consistency will also increase, and when sprayed on a dry, breathable target wall, its consistency will decrease rapidly. It follows that the consistency of the ash is constantly changing.
Therefore, in this embodiment, the ultrasonic generator generates ultrasonic vibration while the scraper is smoothing the ash, and the ash consistency sensor is used to obtain the consistency of the ash at the scraper, so as to obtain real-time data of the consistency of the ash, and compare the implementation data of the consistency with the preset value of the ash set inside the control component. If the acquired consistency value of the ash is lower than the preset value, the control element adjusts the output power of the ultrasonic generating device according to the consistency value of the ash, so that the vibration intensity of the scraper is adjusted in time, the scraper is in the optimal vibration intensity, and the ash and the optimal vibration intensity resonate.
In one embodiment of the present application, the relationship between the solidity value and the vibration intensity is: vibration intensity is the first scale factor (preset value-consistency value). And adjusting the vibration intensity of the scraper comprises adjusting the output power of a driving piece for driving the scraper to vibrate, wherein the output power is the vibration intensity of a second proportionality coefficient.
In this application, the driving piece is the ultrasonic vibrator among the ultrasonic wave generating device, and the control changes the output of ultrasonic vibrator through the consistency value that grey material consistency sensor acquireed, changes the vibration frequency of ultrasonic vibrator to change the vibration intensity of scraping plate, and then make the vibration intensity of scraping plate correspond with current grey material consistency.
The output power of the ultrasonic vibrator is equal to a first scaling coefficient and a second scaling coefficient (a preset value-a consistency value), wherein the value of the first scaling coefficient and the value of the second scaling coefficient are 0.38-0.42. The value of the first proportionality coefficient and the value of the second proportionality coefficient are taken as 0.4, and the power corresponding to different consistency values of the ultrasonic vibrator and the ash material is shown in the following table 1.
TABLE 1 ultrasonic vibrator power corresponding to different thickness values of ash
| Thickness value | Output power (kW) |
| 6 | 1.6 |
| 7 | 1.2 |
| 8 | 0.8 |
| 9 | 0.4 |
| 10 | 0 |
In the present application, as shown in table 1, when the ash consistency sensor obtains the consistency value of the ash at the current position of the scraper, the control element controls the ultrasonic vibrator to stop working when the consistency value is not lower than the preset value, so as to stop the ultrasonic vibration of the scraper.
Specifically, when the consistency value of the lime obtained by the lime consistency sensor is 10, the lime is in an ideal state, the fluidity of the lime is good, when the scraper is used for plastering the lime in the consistency value state, the ultrasonic vibrator is not needed to generate ultrasonic vibration to compact the lime, and at the moment, the scraper can discharge gaps or bubbles of the lime in the plastering process of the lime, so that the phenomenon of hollowing inside the lime is prevented after the lime is solidified.
In the application, when the value of the putty obtained by the putty consistency sensor is greater than 10, after the putty in the state is leveled, the putty cannot be shaped on a target wall surface due to the overlarge fluidity of the putty in the state. Therefore, the mortar in this state is not suitable for leveling, and needs to be placed for a period of time and naturally ventilated to change the consistency value of the mortar, and when the consistency value of the mortar is greater than or equal to 6 and less than or equal to 10, the mortar is leveled on the target wall surface by adopting the process provided by the embodiment.
In particular, the consistency of the ash can also be changed by changing the proportioning of the raw materials of the ash.
In an embodiment of the application, the obtaining of the consistency value of the ash at the current position of the scraper by the plastering process includes obtaining the consistency value of the ash at the current position of the scraper at a first time, and obtaining the consistency value of the ash at the current position of the scraper at a preset time after the first time.
In the application, when the consistency value of the mortar is more than or equal to 6 and less than or equal to 10, the scraper moves on the target wall surface under the driving of the plastering robot for plastering the mortar, and the consistency of the mortar at different parts is inconsistent due to the uneven flatness of the target wall surface after construction and the uneven thickness of the mortar sprayed on the target wall surface. Therefore, in the process of leveling the mortar by the scraper, the consistency value of the mortar on the inner target wall surface needs to be measured for multiple times at preset time, so that the control element can adjust the power output by the ultrasonic vibrator under the consistency value in time through the consistency values measured at different times.
Specifically, when the scraper is at the initial position, the first time is counted, the ash consistency sensor acquires the ash consistency value of the scraper located at the current position and feeds the ash consistency value back to the control element, and the control element adjusts the output power of the scraper according to the corresponding consistency value at the current position. When the scraping plate scrapes the ash material, the ash material consistency sensor acquires the consistency value of the ash material under the current position of the scraping plate at intervals of preset time, and feeds the consistency value back to the control part in sequence, and the control part adjusts the output power of the corresponding ultrasonic vibrator under the consistency value according to the consistency value of the ash material.
In the present application, the preset time is greater than 0ms and less than or equal to 10 ms.
In one embodiment of the present application, the blade is ultrasonically vibrated after the material is leveled until the blade reaches a predetermined cleanliness.
In this application, plastering robot drives the scraper blade and moves to the bottom of target wall along the top of vertical direction follow target wall along the bottom of vertical direction after, plastering robot drives the scraper blade again and moves to the bottom of target wall along the top of vertical direction follow target wall, accomplishes the operation of floating of a lime putty.
After finishing the leveling operation of the ash, the ultrasonic vibrator continues to generate ultrasonic vibration, and the ash adhered to the scraper falls off from the scraper through the ultrasonic vibration, so that the scraper is cleaned, and the scraper reaches the preset cleanliness.
Specifically, in the process that the plastering robot drives the scraper to move from the bottom of the target wall surface to the top of the target wall surface along the vertical direction, the scraper and the advancing direction of the plastering robot form an acute angle along the moving direction of the scraper so as to conveniently level plastering materials by the scraper. In the process that the plastering robot drives the scraper to move from the top of the target wall surface to the bottom of the target wall surface along the vertical direction, the scraper is arranged in parallel with the scraping reference surface and used for improving the plastering precision of the scraper on the plaster.
In one embodiment of the present application, the material is smoothed with a blade that reaches a predetermined degree of cleanliness, and the blade is ultrasonically vibrated in the process.
In this application, ultrasonic vibrator clears up the scraper blade through ultrasonic vibration, accomplishes the clearance back at the scraper blade, and plastering robot drive scraper blade removes in the horizontal direction and screeds the putty of other positions of target wall and screeds the in-process, and ultrasonic vibrator produces the ultrasonic wave and makes the scraper blade produce ultrasonic vibration to the putty of other positions of target wall.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
