Description

Technical Field

[0001] This application relates to the technical field of concrete construction, and more particularly to a concrete leveling device. Background Technology

[0002] In the construction of concrete pavement, leveling is a key process to ensure the flatness, density and subsequent construction quality of the pavement, which directly affects the service life and performance of the pavement.

[0003] Currently, the industry commonly uses vibratory leveling tools to level concrete pavements through vibration, achieving initial leveling and slurry enhancement of the concrete surface. However, existing vibratory leveling tools have a fixed length and their working width cannot be adjusted, resulting in significant limitations in actual construction: for wider concrete pavements, the leveling tool needs to be moved multiple times for segmented leveling, which not only increases construction steps and reduces leveling efficiency but also easily leads to flatness deviations due to segment connections; for narrower pavements or irregularly shaped work areas, the fixed-length leveling tool is not suitable, requiring the replacement with a smaller-sized leveling tool to carry out the work, which not only increases equipment investment costs but also delays construction progress due to equipment replacement, affecting the flexibility and adaptability of leveling operations, and making it difficult to meet the high-efficiency, high-quality leveling requirements for pavements of different widths. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0005] Therefore, one objective of this application is to propose a concrete leveling device that, by setting multiple flexibly adjustable leveling components, can adjust the overall working width according to actual construction needs. It can adapt to different road widths without changing the leveling equipment, and is highly flexible and adaptable, effectively solving the problem of poor adaptability and reduced construction efficiency of existing fixed-length leveling rulers.

[0006] To achieve the above objectives, a first aspect of this application provides a concrete leveling device, comprising a frame, a leveling mechanism, an adjusting mechanism, and a driving mechanism. The leveling mechanism includes multiple leveling components, each of which includes a turntable and two rulers located on the outer side of the turntable, with the two rulers aligned on the same straight line. Adjacent turntables are rotatably connected by a first support arm. The adjusting mechanism includes an adjusting component and multiple positioning seats, each positioning seat being movably fitted onto the outer side of a corresponding turntable. A second support arm is provided between the middle positioning seat and the frame. The adjusting component is connected to the remaining positioning seats. The driving mechanism is connected to the multiple turntables. A shock-absorbing spring is provided between the second support arm and the frame, and a vibrator is mounted on the second support arm.

[0007] In addition, the concrete leveling device proposed in this application may also have the following additional technical features: In one embodiment of this application, the adjusting member includes two adjusting components, each of the adjusting components including a movable seat and two third arms, wherein the two movable seats are slidably disposed on the second arm in sequence; the two third arms are symmetrically arranged relative to the second arm, and one end of each third arm is rotatably connected to the corresponding movable seat and the other end is rotatably connected to the corresponding positioning seat.

[0008] In one embodiment of this application, the drive mechanism includes a motor and a plurality of synchronous belts, wherein each of the turntables is coaxially connected to a drive shaft, and adjacent drive shafts are connected by the synchronous belts; the motor is mounted on the second support arm, and the output end of the motor is connected to the middle drive shaft.

[0009] In one embodiment of this application, the synchronization belt is disposed inside the corresponding first support arm.

[0010] In one embodiment of this application, both sides of the bottom surface of the turntable and both sides of the bottom surface of the ruler are arc-shaped.

[0011] In one embodiment of this application, the first support arm is rotatably connected to the positioning seat.

[0012] In one embodiment of this application, the second arm is inclined relative to the leveling member.

[0013] Compared with the prior art, the beneficial effects of this application are: 1. This application, by setting multiple flexibly adjustable leveling components, can adjust the overall working width according to actual construction needs. It can adapt to different road widths without changing the leveling equipment, and is highly flexible and adaptable. It effectively solves the problem of poor adaptability and reduced construction efficiency of existing fixed-length leveling rulers. 2. The multiple leveling components of this application can rotate synchronously during vibration. Compared with the traditional leveling ruler that can only vibrate up and down, it can make the slurry distribution on the concrete surface more uniform, significantly improve the smoothness and density of the road surface, reduce quality problems such as slurry heaving and sanding, and greatly reduce the workload of subsequent finishing work, speed up the construction progress, improve the construction efficiency, and ultimately effectively improve the construction quality of concrete pavement and extend the service life of the pavement. It is both practical and economical. 3. Compared with traditional leveling rulers that move in one direction, this application has a certain width in both the horizontal and vertical directions after adjusting multiple leveling parts into an arc shape, which enables this application to perform horizontal and / or vertical moving leveling operations, further improving operational flexibility and adaptability.

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0018] The concrete leveling device according to an embodiment of this application will now be described with reference to the accompanying drawings.

[0019] like Figures 1-6 As shown, the concrete leveling device of this application embodiment includes a frame 10, a leveling mechanism, an adjusting mechanism 30, and a driving mechanism 40.

[0020] The leveling mechanism includes multiple leveling components 20, wherein each leveling component 20 includes a turntable 21 and two rulers 22 located outside the turntable 21, wherein the two rulers 22 are located on the same straight line, and adjacent turntables 21 are rotatably connected by a first support arm 50.

[0021] It should be noted that the number of leveling components 20 described in this embodiment is odd. The middle leveling component 20 is connected to the second support arm 60. The position of this leveling component 20 remains unchanged. The adjustment mechanism 30 adjusts the position of the remaining multiple leveling components 20.

[0022] The adjustment mechanism 30 includes an adjustment component and multiple positioning seats 31. The positioning seats 31 are coaxially and movably sleeved on the outside of the corresponding turntable 21. The positioning seats 31 correspond one-to-one with the turntable 21. The first support arm 50 is rotatably connected to the positioning seat 31. A second support arm 60 is provided between the middle positioning seat 31 and the frame 10. The adjustment component is connected to the remaining multiple positioning seats 31.

[0023] It should be noted that the adjusting component described in this embodiment is used to adjust the position of the connected positioning seat 31, so that the positioning seat 31 drives the connected leveling component 20 to rotate and adjust, thereby adapting to road leveling operations of different widths. Specifically, the adjusting component also includes two adjusting assemblies, each adjusting assembly including a movable seat 32 and two third support arms 33. The two movable seats 32 are slidably mounted on the second support arm 60 in sequence, and the two third support arms 33 are symmetrically arranged with respect to the second support arm 60. One end of each third support arm 33 is rotatably connected to the corresponding movable seat 32, and the other end is rotatably connected to the corresponding positioning seat 31.

[0024] In this embodiment, when the movable seat 32 moves on the second support arm 60, the two connected third supports 33 will drive the corresponding positioning seats 31 to move, causing the corresponding first support arm 50 to rotate relative to the adjacent first support arm 50 (the first support arm 50 near the middle leveling member 20). Specifically, as shown... Figure 3 As shown, the positioning seat 31 will adjust its position along an arc trajectory with the other end of the first arm 50 (the first arm 50 near the middle leveling piece 20) connected to it as the center.

[0025] In addition, each movable seat 32 can be operated electrically or manually to slide on the second arm 60, for example, each movable seat 32 is connected to a slide rail motor 41.

[0026] The drive mechanism 40 is connected to multiple turntables 21. It should be noted that the drive mechanism 40 described in this embodiment is used to drive the multiple turntables 21 to rotate individually; specifically, as shown... Figure 5-6As shown, the drive mechanism 40 includes a motor 41 and multiple synchronous belts 42. Each turntable 21 is coaxially connected to a drive shaft 211, and adjacent drive shafts 211 are connected by synchronous belts 42. Each drive shaft 211 has one or two synchronous pulleys positioned vertically on its outer side. The synchronous belts 42 are located inside the corresponding first support arm 50. The motor 41 is mounted on the second support arm 60 via a mounting bracket 12, and the output end of the motor 41 is connected to the intermediate drive shaft 211.

[0027] In this embodiment of the application, after the motor 41 is started, it can drive the drive shaft 211 connected to it to rotate. Under the action of multiple synchronous belts 42, the multiple drive shafts 211 achieve synchronous and unidirectional rotation drive. The connection between adjacent drive shafts 211 by synchronous belts 42 allows the position of the drive shafts 211 to be adjusted smoothly and flexibly.

[0028] A shock-absorbing spring 80 is provided between the second arm 60 and the frame 10, and a vibrator 90 is provided on the second arm 60. In this embodiment, the vibrator 90 has the function of controlling the vibration of the second arm 60. The vibrator 90 cooperates with the drive mechanism 40 and can use a combination of low-speed rotation and high-frequency vibration to make multiple leveling parts 20 rotate synchronously during the vibration process. Compared with the traditional leveling ruler that can only achieve up and down vibration, it can make the slurry distribution on the concrete surface more uniform, significantly improve the smoothness and density of the road surface, reduce quality problems such as slurry heaving and sanding, and greatly reduce the workload of subsequent finishing work, speed up the construction progress, improve the construction efficiency, and ultimately effectively improve the construction quality of concrete pavement and extend the service life of the pavement, which is both practical and economical.

[0029] Specifically, when road leveling is required, the operator can first adjust the overall width of the multiple leveling components 20 according to the road width using the adjustment mechanism 30. Specifically, the operator manipulates the sliding seat 32 of the leveling component 20 closest to the center to slide on the second arm 60, causing the two connected leveling components 20 to rotate symmetrically in an arc. Then, another sliding seat 32 can be adjusted to achieve symmetrical arc rotation of the other two leveling components 20, thereby adjusting the overall width of the multiple leveling components 20 to a suitable size.

[0030] After the width of the leveling component 20 is adjusted, the operator can use the frame 10 to drive multiple leveling components 20 to move linearly on the concrete surface. During this process, the drive mechanism 40 will control the rotation of each leveling component 20, while the vibrator 90 drives the second support arm 60 to vibrate. This vibration is transmitted sequentially through components such as the moving seat 32, the third support arm 33, the positioning seat 31, and the first support arm 50 on the second support arm 60, ultimately causing multiple leveling components 20 to vibrate synchronously.

[0031] Multiple leveling components 20 can vibrate and rotate to smooth the concrete during movement, thus efficiently completing the leveling construction of the concrete pavement.

[0032] As one possible scenario, such as Figure 2 As shown, after adjusting the multiple leveling parts 20 into an arc shape, this application has a certain width in both the horizontal and vertical directions, enabling this application to perform horizontal and / or vertical moving leveling operations, further improving operational flexibility and adaptability.

[0033] In addition, the frame 10 is equipped with adjustable wheels 11 or adopts a caster wheel structure to adapt to lateral and / or longitudinal movement needs.

[0034] In one embodiment of this application, such as Figure 1 As shown, the second support arm 60 is inclined relative to the leveling component 20. It is understood that when multiple leveling components 20 can conform to the concrete pavement, this design allows the positioning rod and adjusting mechanism 30 to be kept away from the concrete pavement, thus protecting them. For example, the angle between the second support arm 60 and the leveling component 20 needs to be greater than 10 degrees.

[0035] In one embodiment of this application, such as Figure 4 As shown, both sides of the bottom surface of the turntable 21 and both sides of the bottom surface of the ruler 22 are curved. Understandably, this design facilitates the rotary scraping operation on concrete pavements.

[0036] In summary, the concrete leveling device of this application embodiment, by setting multiple flexibly adjustable leveling components, can adjust the overall working width according to actual construction needs. It can adapt to road surfaces of different widths without changing the leveling equipment, and is highly flexible and adaptable. It effectively solves the problem of poor adaptability and reduced construction efficiency of existing fixed-length leveling rulers.
