Description
Technical Field
[0001] This utility model relates to the technical field of building construction equipment, specifically to a concrete intelligent ground leveling machine. Background Technology
[0002] When laying concrete, after pouring the concrete into the construction area, it must be leveled before it hardens to ensure a flat surface. This requires the use of a concrete leveling machine. During construction, the ground needs to be manually compacted, then the concrete mix is poured into the construction area using equipment, and then manually spread to a relatively flat surface. Finally, the leveling machine is used to vibrate and compact the concrete.
[0003] In existing technologies, concrete screeds primarily level concrete substrates by using a fixed-height scraper. This traditional leveling method relies on a pre-set scraper height, with the screed moving across the concrete surface and mechanically scraping the concrete to achieve initial leveling.
[0004] The shortcomings of the existing technical solutions are as follows: due to the uneven height of the concrete base layer at the construction site, when the concrete leveling machine travels on the uneven base layer, there will be a significant height difference in the machine body. The fixed-height scraper cannot be adjusted in real time with the undulation of the base layer, which can easily lead to scraping too deep or too shallow, resulting in poor pre-leveling effect and even damage to the concrete base layer structure.

[0022] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.
[0023] First Embodiment
[0024] Please see Figures 1 to 4As shown, a concrete intelligent floor leveling machine includes a frame 1, wheels 2, a leveling mechanism 3, and a control terminal 4. Several wheels 2 are arranged and fitted onto the bottom sides of the frame 1. The leveling mechanism 3 is electrically connected to the control terminal 4. The leveling mechanism 3 includes a mounting base 5, a rotating frame 6, a mounting bracket 7, a support frame 8, a scraper 9, a signal output component, and a signal receiving component 10. The mounting base 5 is fixedly connected to the frame 1. One end of the rotating frame 6 is hinged to the mounting base 5, and the other end of the rotating frame 6 is hinged to the mounting bracket 7. The support... The frame 8 is vertically fixedly connected to the mounting frame 7, and the scraper 9 is horizontally fixedly connected to the mounting frame 7. The signal output component includes an infrared emitter, which is used to emit horizontal infrared rays. The signal receiving component 10 is provided in two sets and is symmetrically arranged on both sides of the support frame 8. The signal receiving component 10 includes a movable slide plate 11 and an infrared sensor 12. The movable slide plate 11 is connected to the support frame 8. Several infrared sensors 12 are provided and are arranged in a rectangular array on the side of the movable slide plate 11.
[0025] When the intelligent concrete floor leveling machine is working, the frame 1 moves via several wheels 2 on both sides of the bottom. The leveling mechanism 3 is electrically connected to the control terminal 4. During the leveling operation, the infrared transmitter emits infrared rays that are horizontal and at a fixed height. Since there are two sets of signal receiving components 10 arranged symmetrically on both sides of the support frame 8, the movable slide plate 11 is connected to the support frame 8, and the infrared sensors 12 are arranged in a rectangular array on the side of the movable slide plate 11, the infrared sensors 12 receive the infrared rays emitted by the infrared transmitter when the leveling machine moves on the concrete surface.
[0026] If the concrete surface height is inconsistent, the movable slide plate 11 will change position according to the undulations of the concrete surface, thereby causing the infrared sensor 12 to shift relative to the infrared rays. The infrared sensor 12 transmits the detected displacement signal to the control terminal 4 in real time. The control terminal 4 analyzes and processes the received signal to determine the deviation between the current concrete surface and the preset leveling height. Then, the control terminal 4 sends a command to the leveling mechanism 3, which adjusts the hinge angle between the rotating frame 6 and the mounting base 5 and mounting frame 7, thereby causing the mounting frame 7, support frame 8, and scraper 9 to adjust their positions accordingly. This allows the height of the scraper 9 to adapt to the changes in the concrete surface height in real time, thus achieving precise leveling of the concrete surface.
[0027] The infrared transmitter and the infrared sensors 12 arranged in a rectangular array can accurately detect changes in the height of the concrete surface and transmit the signal to the control terminal 4 in real time. The control terminal 4 automatically adjusts the height of the scraper 9 according to the signal, eliminating the need for frequent manual operation, which greatly improves the automation and efficiency of the leveling operation and reduces labor costs and labor intensity.
[0028] The infrared sensor 12 enables the leveling machine to detect height differences on the concrete surface in a timely and accurate manner, and adjust the height of the scraper 9 in real time for leveling, effectively ensuring the flatness of the leveled ground, meeting the requirements of high-quality construction, and improving the quality of the project.
[0029] Second Embodiment
[0030] Based on the first embodiment, the leveling mechanism 3 further includes a signal light 13, which is fixedly connected to the movable slide plate 11. All infrared sensors 12 are divided into a first receiving group, a second receiving group, and a third receiving group from top to bottom. The signal light 13, the first receiving group, the second receiving group, and the third receiving group are all electrically connected to the control terminal 4. The signal light 13 includes a mounting plate 14, a lower triangular light 15, a straight light 16, and an upper triangular light 17. The mounting plate 14 is fixedly connected to the movable slide plate 11. The lower triangular light 15 is fixedly disposed on the upper side of the mounting plate 14, the upper triangular light 17 is fixedly disposed on the lower side of the mounting plate 14, and the straight light 16 is fixedly disposed on the side of the mounting plate 14 and located between the lower triangular light 15 and the upper triangular light 17. The lower triangular light 15 and the upper triangular light 17 emit red light, and the straight light 16 emits green light.
[0031] During the leveling process, infrared sensor 12 receives infrared rays emitted by the infrared transmitter in real time. When the concrete surface height is inconsistent, the movable slide plate 11 causes the infrared sensor 12 to shift relative to the infrared rays, and the infrared sensor 12 transmits the detected signal to the control terminal 4. At the same time, the indicator lights 13 on the movable slide plate 11 are electrically connected to the control terminal 4. The lower triangular light 15, the straight light 16, and the upper triangular light 17 will light up according to the deviation of the current concrete surface from the preset leveling height. When the infrared sensor 12 of the first receiving group receives infrared rays, the lower triangular light 15 lights up red, indicating that the concrete surface is below the preset height; when the infrared sensor 12 of the second receiving group receives infrared rays, the straight light 16 lights up green, indicating that the concrete surface is within the preset height range; when the infrared sensor 12 of the third receiving group receives infrared rays, the upper triangular light 17 lights up red, indicating that the concrete surface is above the preset height.
[0032] The indicator lights 13 allow operators to intuitively understand the height deviation of the concrete surface without constantly monitoring the data on the control terminal 4, thus improving operational convenience and efficiency. Simultaneously, the division into different receiving groups helps to more accurately determine the range of height changes on the concrete surface, providing more detailed signals to the control terminal 4, thereby further improving the leveling accuracy and ensuring the flatness of the leveled ground.
[0033] Third Embodiment
[0034] Based on the first embodiment, the leveling mechanism 3 further includes a first telescopic rod 18. One end of the first telescopic rod 18 is hinged to the mounting base 5, and the telescopic end of the first telescopic rod 18 is hinged to the rotating frame 6. The first telescopic rod 18 is electrically connected to the control terminal 4, and the first telescopic rod 18 is an electric push rod. The control terminal 4 sends a command to the first telescopic rod 18 based on the concrete surface height deviation signal detected by the infrared sensor 12. The telescopic end of the first telescopic rod 18 performs telescopic movement, changing the hinge position with the rotating frame 6, thereby driving the rotating frame 6 to rotate around the hinge point with the mounting base 5, and thus adjusting the height of the mounting frame 7, the support frame 8, and the scraper 9. This allows the scraper 9 to adapt to the height changes of the concrete surface in real time, achieving leveling of the concrete surface.
[0035] Fourth embodiment
[0036] Based on the first embodiment, the leveling mechanism 3 further includes a first support 19, a second telescopic rod 20, a second support 21, a roller 22, a rubber column 23, a vibrating plate 24, and an attached plate vibrator 25. The first support 19 is fixedly connected to the frame 1, the second telescopic rod 20 is fixedly connected to the first support 19, the telescopic end of the second telescopic rod 20 is fixedly connected to the second support 21, the roller 22 is horizontally connected to the second support 21 in a rotatable fit, the top of the rubber column 23 is fixedly connected to the mounting frame 7, the bottom of the rubber column 23 is fixedly connected to the vibrating plate 24, the attached plate vibrator 25 is fixedly installed on the top of the vibrating plate 24, and the second telescopic rod 20 is an electric push rod.
[0037] During the leveling operation, the telescopic end of the second telescopic rod 20 extends and retracts, causing the second support 21 and roller 22 to move up and down. This allows the roller 22 to adaptively adjust according to the height of the concrete surface, initially compacting and leveling the concrete surface. Next, the attached plate vibrator 25 is activated, causing the vibrating plate 24 to vibrate. The vibrating plate 24 further vibrates and compacts the concrete surface, making the concrete denser and improving the strength and smoothness of the ground. Simultaneously, the rubber columns 23 absorb and buffer vibrations, preventing direct rigid transmission of vibrations to the mounting frame 7 and affecting other components.
[0038] Fifth Embodiment
[0039] Based on the first embodiment, the support frame 8 has a first vertical slide groove 26 and a second vertical slide groove 27 on both sides. The movable slide plates 11 in the two sets of signal receiving components 10 are a first slide plate 28 and a second slide plate 29, respectively. The first slide plate 28 is slidably connected to the first slide groove 26, and the second slide plate 29 is slidably connected to the second slide groove 27. The leveling mechanism 3 also includes a first lead screw 30 and a second lead screw 31. The first lead screw 30 and the second lead screw 31 are rotatably disposed in the first slide groove 26 and the second slide groove 27, respectively, in a vertical state. The first slide plate 28 has a first screw hole that is threadedly connected to the first lead screw 30, and the second slide plate 29 has a second screw hole that is threadedly connected to the second lead screw 31. The leveling mechanism 3 also includes a rotating shaft 32, a driving bevel gear 33, and a driven bevel gear 34. The rotating shaft 32 is horizontally connected to the support frame 8 in a rotatable engagement. Two driving bevel gears 33 and two driven bevel gears 34 are provided. The two driving bevel gears 33 are coaxially and fixedly connected to both ends of the rotating shaft 32, and the two driven bevel gears 34 are coaxially and fixedly connected to the first lead screw 30 and the second lead screw 31, respectively. The driving bevel gears 33 mesh with their corresponding driven bevel gears 34. The leveling mechanism 3 also includes a drive motor 35, two pulleys 36, and a synchronous belt 37. The drive motor 35 is fixedly connected to the support frame 8. The two pulleys 36 are coaxially and fixedly connected to the output end of the drive motor 35 and the rotating shaft 32, respectively. The synchronous belt 37 is positioned between the two pulleys 36.
[0040] When the position of the signal receiving component 10 needs to be adjusted according to different construction requirements and concrete surface conditions, the drive motor 35 is started, driving the rotating shaft 32 to rotate through the transmission of the pulley 36 and the synchronous belt 37. The driving bevel gears 33 at both ends of the rotating shaft 32 mesh with the driven bevel gears 34 on the first lead screw 30 and the second lead screw 31, respectively, thereby driving the first lead screw 30 and the second lead screw 31 to rotate synchronously. Since the first sliding plate 28 and the second sliding plate 29 are threadedly connected to the first lead screw 30 and the second lead screw 31, respectively, and slide in the first sliding groove 26 and the second sliding groove 27, respectively, the rotation of the first lead screw 30 and the second lead screw 31 will drive the first sliding plate 28 and the second sliding plate 29 to move in the vertical direction, thereby adjusting the height of the movable sliding plate 11 and the infrared sensor 12, realizing the adjustment of the position of the signal receiving component 10, and enhancing the adaptability and versatility of the equipment.
