Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of construction devices, and in particular to a precision control device for high-precision flooring and a control method thereof. Background Art
[0002] In the construction of high-precision flooring, traditional methods mainly rely on manual measurement and adjustment, which makes it difficult to ensure construction accuracy and prone to flatness deviations; construction efficiency is low and relies on the experience of operators; it is impossible to monitor construction quality in real time, which easily leads to rework and other problems.
[0003] In order to solve the above problems, some laser levels and automatic leveling devices have been introduced in the prior art. The laser transmitter sends a laser signal to the laser receiver installed on the floor machine. When the laser receiver receives the laser emission signal, it indicates that the two heights are consistent. When the laser receiver cannot receive the laser signal, it indicates that the two heights are inconsistent. Then a signal is sent to the control system to command the floor machine to adjust the height until the laser receiver can receive the laser signal, so that the leveling height of the floor machine is within a certain range, so that leveling does not require pulling a control line or supporting side templates to control the ground elevation. Instead, it is controlled in real time by the laser measurement and control system on the laser leveling machine. As long as the laser transmitter is not interfered with, no matter where the laser leveling machine is moved, it can ensure that the overall elevation of the paved ground is not affected.
[0004] However, in the above method, when the laser receiver cannot receive the laser emission signal, it can only determine that the height of the floor machine is not within the specified range, and cannot determine whether the height of the floor machine is too high or too low. Therefore, it can only be adjusted by first up and then down or first down and then up. It is easy to make the direction adjustment wrong when first up or first down. Then a second direction adjustment is required to find the correct adjustment direction, which will cause unnecessary waste of time and affect construction efficiency. At the same time, the laser emission is emitted in the form of a beam. When the floor machine moves, the position of the laser receiver changes. The laser transmitter needs to be manually adjusted and tracked or rotated to generate a horizontal beam to ensure that the laser emission is aligned with the laser receiver. However, the manual adjustment method is not only time-consuming and labor-intensive, but also has extremely low adjustment efficiency, requires repeated alignment, and has very low accuracy. The horizontal beam method depends on the continuous rotation of the laser transmitter, which not only consumes electricity, but also produces many moments that cannot be aligned during the rotation process. Therefore, there are many moments that cannot be aligned. These small moments will cause the laser light receiver to have a moment when it cannot receive the laser signal, thereby affecting the control accuracy of the control system and affecting the flatness accuracy of the floor. Summary of the invention
[0005] The purpose of the present invention is to provide a precision control device and a control method for high-precision flooring to solve the following technical problems:

[0011] Furthermore: the three-stage receiving part includes an upper receiving part, a middle receiving part, and a lower receiving part from top to bottom, and each of the three has an independent signal feedback module that is communicatively connected to the control system.
[0012] Furthermore: the two laser receivers are respectively vertically mounted on the vibration plate through vertical rods, and the horizontal heights of the two laser receivers are the same.
[0013] Furthermore: the laser transmitter is used to emit a horizontal laser beam, the standard horizontal height of the horizontal laser beam is the horizontal height of the middle section of the receiving part, and the laser emission direction is always toward the laser receiver.
[0014] Furthermore: the angle sensor is used to sense the rotation direction of the wheel drive shaft of the floor scooter.
[0015] Furthermore: the support frame is provided with a height adjustment device for adjusting the height of the laser emitter.
[0016] Furthermore: the angle adjustment module is used to adjust the horizontal rotation angle of the laser transmitter.
[0017] Furthermore: a control console is installed at one end of the floor machine away from the vibration plate to control the movement trajectory of the floor machine.
[0018] Furthermore: the floor machine is equipped with a display screen for displaying data information on the flatness, levelness and thickness of the floor.
[0019] In a second aspect, the present invention further discloses a control method for the precision control device for high-precision flooring as described above, comprising the following steps:
[0020] Step 1: Set the reference point of the floor and adjust the horizontal heights of the two laser receivers to be exactly the same according to the reference point;
[0021] Step 2: Position the support frame and adjust the height of the support frame so that the laser emission level of the laser transmitter is the same as the center point of the middle receiving part of the laser receiver. At the same time, start the laser transmitter and calibrate it so that the laser emission direction is aligned with the laser receiver.
[0022] Step 3: Control the motion trajectory of the floor machine through the control console.

Compared with the one-section receiving part of the laser receiver in the prior art, it can avoid the problem that the receiving part is unclear about upward or downward adjustment when the laser transmission signal cannot be received and then performs tentative up and down adjustments, saving the wasted time caused by trial errors, thereby improving the control efficiency, and helping to reduce construction time and enhance construction efficiency.
[0027] 2. The precision control device for high-precision flooring of the present invention identifies the position and movement angle of the flooring machine by arranging an angle sensor on the wheel drive shaft of the flooring machine, and transmits the signal to the control system.

Therefore, the signal feedback accuracy of the laser receiver can be improved, thereby improving the adjustment accuracy of the control system on the vibration plate of the flooring machine, so that the flatness of the floor can be better achieved.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] Example 1
[0034] This embodiment discloses a precision control device for high-precision flooring.
[0035] See also Figure 1The precision control device includes a floor machine 100. The front end of the floor machine 100 drives a vibration plate 101 through a vibration motor, and the vibration plate 101 is used to smooth the ground; a control panel 102 is installed at the rear end of the floor machine 100, and the staff can perform various types of operations on the floor machine 100 through the control panel 102, so that the floor machine 100 moves according to the set route trajectory; a display screen 103 is installed on the floor machine 100 to display data information on the flatness, levelness and thickness of the floor; the floor machine 100 is built-in with a control system to control the precision control device; an angle sensor is installed on the wheel drive shaft of the floor machine 100 to sense the angle change information of the wheel drive shaft of the floor machine 100.
[0036] Vertical rods 200 are respectively installed on the upper sides of both ends of the vibration plate 101, and the two vertical rods 200 are symmetrically arranged about the center of the vibration plate 101; laser receivers 300 are respectively installed on the tops of the two vertical rods 200, and the horizontal heights of the two laser receivers 300 are the same; the receiving part of the laser receiver 300 is a three-section receiving part, which is divided into an upper receiving part, a middle receiving part and a lower receiving part from top to bottom; the three receiving parts respectively correspond to independent signal feedback modules that are communicatively connected with the control system; among them, the height range of the middle receiving part is a standard height range, and its range value can be set according to the actual floor flatness requirements.
[0037] See also Figure 2 The precision control device also includes a support frame 400, a laser emitter 500 is installed on the top of the support frame 400, and the laser emitter 500 is built with an angle adjustment module for adjusting the laser emission angle of the laser emitter 500; the laser emission direction of the laser emitter 500 needs to be always aligned with the laser receiver 300 to ensure that the laser receiver 300 can receive the laser emission signal within the allowable height range; a height adjustment device is provided on the support frame 400 to adjust the overall height of the support frame 400, thereby adjusting the height of the laser emitter 500; it should be noted that the structure of the height adjustment device is not limited, and it only needs to meet the requirement of the adjustable height of the support frame 400, so a structure that meets the requirements in the prior art can be adopted, which will not be repeated here.
[0038] The floor machine 100 adjusts its direction by rotating the wheel drive shaft. Therefore, the change of the wheel drive shaft determines the movement trajectory of the floor machine 100. When the floor machine 100 moves, the laser receiver 300 above it moves accordingly. Therefore, the laser transmitter 500 needs to track its position to ensure that the laser emission direction is always aligned with the laser receiver 300; and the angle sensor can sense the angle change of the wheel drive shaft, and can transmit the angle change signal of the angle change to the control system. The control system has a built-in algorithm program, which can bring the angle change information into the algorithm program, calculate the angle value that needs to be changed for the laser emission direction of the laser transmitter 500 to align with the laser receiver 300, that is, the angle adjustment command signal, and the control system sends the angle adjustment signal to the angle adjustment module of the laser transmitter 500. The angle adjustment module controls the laser transmitter 500 to rotate in the horizontal direction according to the signal value, so that the laser emission direction is aligned with the laser receiver 300, so as to realize the tracking of the laser transmitter 500 to the laser receiver 300, and achieve the purpose of always aligning the laser emission signal with the laser receiver 300.
[0039] The laser transmitter 500 emits laser to the laser receiver 300. When the middle receiving part on the laser receiver 300 receives a signal, it means that the height of the vibration plate 101 is within the standard range; when the upper receiving part on the laser receiver 300 receives a signal, it means that the height of the vibration plate 101 is less than the standard height, and the vibration plate 101 should be adjusted up; when the lower receiving part on the laser receiver 300 receives a signal, it means that the height of the vibration plate 101 is greater than the standard height, and the vibration plate 101 should be adjusted down.
[0040] After the laser receiver 300 receives the laser emission signal, if the middle receiver receives the laser signal, the signal feedback module of the middle receiver sends a signal to the control system, and the control system sends a signal to the vibration motor after receiving the signal, so that the vibration motor maintains the current height; if the upper receiver receives the laser signal, the signal feedback module of the upper receiver sends a signal to the control system, and the control system sends a signal to the vibration motor after receiving the signal, so that the vibration motor adjusts the height upward until the middle receiver receives the laser emission signal and sends it to the control system; if the lower receiver receives the laser signal, the signal feedback module of the lower receiver sends a signal to the control system, and the control system sends a signal to the vibration motor after receiving the signal, so that the vibration motor adjusts the height downward until the middle receiver receives the laser emission signal and sends it to the control system; thereby ensuring that the height of the vibration plate 101 is always within the standard range, thereby ensuring that the levelness of the floor is within the set range.
[0041] Example 2
[0042] This embodiment discloses a control method for the precision control device for high-precision floor in Embodiment 1, comprising the following steps:
[0043] Step 1: Set the reference point of the floor, and adjust the horizontal heights of the two laser receivers 300 to be exactly the same according to the reference point;
[0044] Step 2: Position the support frame 400 and adjust the height of the support frame 400 so that the laser emission level of the laser transmitter 500 is the same as the center point level of the middle receiving part of the laser receiver 300. At the same time, start the laser transmitter 500 and calibrate it so that the laser emission direction is aligned with the laser receiver 300.
[0045] Step 3: Control the motion trajectory of the floor machine 100 through the control console 102. During the motion of the floor machine 100, the angle sensor sends an angle change signal of the central axis of the wheel to the control center. The control system performs an algorithm program according to the angle change signal, obtains an angle adjustment command signal and sends it to the angle adjustment module. The angle adjustment module drives the laser transmitter 500 to adjust the angle according to the signal, so that the laser emission direction is always aligned with the laser receiver 300 and sends a laser height signal.
[0046] Step 4: The laser receiver 300 transmits the received laser height signal to the control system. The control system performs an algorithm program according to the laser height signal to obtain an action command signal, and sends the signal to the vibration motor. The vibration motor performs corresponding action adjustment according to the action command signal, thereby driving the vibration plate 101 to adjust the leveling height until the horizontal height of the laser emission is within the horizontal height range of the middle section of the receiving part.
[0047] Step 5: Conduct a comprehensive inspection of the floor after construction is completed.
