Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a leveling device for a water-permeable prefabricated paved road surface. Background Art

[0002] Sponge cities can use permeable pavement to achieve the permeability of the road surface, and maintaining the flatness of the permeable pavement is one of the important indicators to ensure its normal operation and provide a good service level. Flatness refers to the intermittent or continuous measurement of the road surface according to the specified standards to evaluate its unevenness, which directly reflects the flatness of the permeable pavement structure layer.

[0003] Common permeable pavement is paved with prefabricated permeable concrete suspended slabs. Because the suspended slabs are not tightly connected to the base layer, uneven areas are easily produced during the construction process. The uneven road surface not only reduces the aesthetic effect, but also causes additional vibrations when the vehicle is driving, resulting in an increased sense of bumpiness, which further brings additional impact to the road surface and affects the service life of the permeable pavement. Especially in high-frequency and high-load areas such as highway service area parking lots, airport runways, and port terminals, the flatness requirements are higher. Therefore, in the construction of permeable pavement, flatness control is very important.

[0004] At present, common leveling devices usually adopt a linear structure. During the leveling process, the joints between the suspended plates cannot form a stable push and fill against external forces, resulting in the inability to keep the elevations of the layers consistent and gaps. In addition, the linear leveling device can only be leveled in a single direction, making it difficult to cover the entire area and leaving loopholes. The above problems lead to low leveling efficiency in the existing technology, making it difficult to achieve high-precision leveling. Once local unevenness occurs, it is very easy to expand and spread. Therefore, a new type of efficient and high-precision leveling device is urgently needed to improve the construction quality of permeable pavement, extend its service life, and meet the requirements of sponge city construction for the flatness of permeable pavement.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: As shown in the figure, a leveling device for a permeable prefabricated paved road surface includes a leveling plate 1, and also includes two brackets 2 spaced apart on the left and right, an adjustment mechanism 3 for adjusting the distance between the two brackets 2 is arranged between the two brackets 2, a movable seat 4 is movably arranged on each bracket 2, the leveling plate 1 is connected between the two movable seats 4, and a serrated portion 5 for contacting with the road surface is arranged at the lower part of the leveling plate 1.

[0026] Embodiment 2: As shown in the figure, the difference from Embodiment 1 is that a first telescopic support 6 is fixed to one end of each bracket 2, a second telescopic support 7 is fixed to the other end of each bracket 2, pads 8 are fixed to the bottom of the first telescopic support 6 and the second telescopic support 7, and a universal wheel 9 and an adjustment foot 10 are fixed to the lower end of the pad 8.

[0027] This structural design of the bracket 2 has the following advantages: the setting of the first telescopic support 6 and the second telescopic support 7 enables the bracket 2 to adjust its height to meet the construction requirements of different road surfaces. At the same time, it is supported at both ends, the force in the middle is more uniform, and the overall structure is more stable; the presence of the pad 8 disperses the force of the bracket 2 to a larger area, reducing the local pressure on the road surface and avoiding causing new unevenness. The combined design of the pad 8 and the universal wheel 9 gives the bracket 2 good mobility. The universal wheel 9 can turn freely 360 degrees, so that the entire device can turn freely during operation and meet corners, which is convenient for covering various areas. The adjustable foot can adapt to the slight ups and downs of the road surface and keep the bracket 2 in a horizontal state, so that the leveling device has good adaptability, flexibility and stability, which helps to improve the leveling efficiency and accuracy.

[0028] In this embodiment, the adjustment mechanism 3 includes two cross-distributed connecting rods 11, and a pin shaft 12 is connected to the middle part of the two connecting rods 11. A mounting plate 13 is fixed to the inner side of each bracket 2, and a slide groove 14 is opened on the mounting plate 13. An adjusting bolt 15 is slidably arranged in each slide groove 14. A mounting seat 16 is fixed to the upper part of the first telescopic pillar 6. One end of the first connecting rod 11 is hinged to the mounting seat 16 of the left first telescopic pillar 6, and one end of the right adjusting bolt 15 passes through the slide groove 14 and is screwed to the other end of the first connecting rod 11. One end of the second connecting rod 11 is hinged to the mounting seat 16 of the right first telescopic pillar 6, and one end of the left adjusting bolt 15 passes through the slide groove 14 and is screwed to the other end of the second connecting rod 11.

[0029] In the above structure, one end of the first connecting rod 11 is connected to the mounting seat 16 of the left first telescopic support 6 by an articulated manner, and the other end is connected by a sliding screw connection of the right adjusting bolt 15. One end of the second connecting rod 11 is also connected to the mounting seat 16 of the right first telescopic support 6 by an articulated manner, and the other end is connected by a sliding screw connection of the left adjusting bolt 15. Through this ingenious connecting rod structure design, a scissor-type structure is formed. When the adjusting bolt 15 on either side is rotated, the connecting rod 11 will produce relative movement, thereby changing the distance between the two brackets 2. The design of articulation and sliding screw connection enables the entire adjustment process to be completed smoothly and accurately, so as to conveniently adjust the coverage of the leveling plate 1 according to different road widths and avoid missing dead corners.

[0030] Embodiment 3: As shown in the figure, the difference from Embodiment 2 is that each bracket 2 is provided with a driving mechanism 17 for driving the corresponding moving seat 4 to move.

[0031] In this embodiment, each driving mechanism 17 includes a fixed plate 18, a driving motor 19, a screw rod 20 and a nut seat 21. The fixed plate 18 is fixed to the lower end of the bracket 2, and reinforcing plates 22 are distributed and fixed at the front and rear ends of the fixed plate 18. The screw rod 20 is rotatably connected between the two reinforcing plates 22. The driving motor 19 is fixed on one of the reinforcing plates 22, and the output shaft of the driving motor 19 is coaxially connected to the screw rod 20. The nut seat 21 is screwed on the screw rod 20. The movable seat 4 is fixed on the nut seat 21. A guide assembly 23 is also arranged between the movable seat 4 and the fixed plate 18.

[0032] The leveling device is also provided with a driving mechanism 17 on the bracket 2 for driving the leveling plate 1 to move along the road surface for leveling operation.

[0033] During operation, the driving motor 19 drives the screw rod 20 to rotate. Since the nut seat 21 is screwed on the screw rod 20, as the screw rod 20 rotates, the nut seat 21 will generate linear reciprocating motion under the action of the screw rod 20. Since the moving seat 4 is fixed on the nut seat 21, it will also generate linear reciprocating motion. Through the guidance of the guide assembly 23, the movement of the moving seat 4 is kept on the correct track. The leveling plate 1 is connected between the two moving seats 4 to achieve precise movement along the road surface.

[0034] The driving mechanism 17 is reasonably designed and compact in structure. The motor provides power, the screw rod 20 and the nut seat 21 realize movement, and the guide assembly 23 ensures the movement trajectory, which effectively avoids the displacement deviation of the leveling plate 1 during movement. At the same time, this driving method can realize the forward and reverse movement of the leveling plate 1, which is convenient for operation. This design enables the leveling device to move autonomously, greatly improves the working efficiency, reduces the manpower burden, and is beneficial to the control of the construction quality and construction period of the permeable paving.

[0035] In this embodiment, the guide assembly 23 includes two guide rails 24 and two sliders 25. The two guide rails 24 are fixed on the fixed plate 18 at intervals up and down. The screw rod 20 is located between the two guide rails 24. The two sliders 25 are fixed on the side wall of the movable seat 4 at intervals up and down, and each slider 25 is slidably arranged on the corresponding guide rail 24.

[0036] When the drive mechanism 17 is working, when the screw rod 20 rotates under the drive of the drive motor 19, the nut seat 21 will drive the moving seat 4 to produce linear reciprocating motion. At this time, the slider 25 will slide on the corresponding guide rail 24, playing the role of limiting and guiding, so that the motion trajectory of the moving seat 4 remains on a precise straight line to avoid displacement deviation. The guide component 23 is compact in design and simple in structure. The guide rail 24 provides precise linear motion guidance. The slider 25 can slide smoothly under the constraint of the guide rail 24 to avoid jamming. At the same time, the setting of the upper and lower sets of guide rails 24 and sliders 25 makes the guidance more reliable and the movement more stable. In general, this design ensures the position accuracy of the leveling plate 1 during operation, which is conducive to obtaining a uniform and high-quality leveling effect.

[0037] In addition, the guide rail 24 and the slider 25 are made of wear-resistant materials, have a long service life, are easy to maintain, and have high overall operational reliability, which is conducive to the long-term use of the leveling device.

[0038] Embodiment 4: As shown in the figure, the difference from Embodiment 3 is that a bending plate 26 is fixed to the upper end of the leveling plate 1, a slot 27 is provided on each movable seat 4, the left and right ends of the bending plate 26 are respectively connected to the corresponding slots 27, and the movable seat 4 is also connected to a locking bolt 28 for locking the bending plate 26 in the slot 27.

[0039] In the above structure, a bending plate 26 is fixed to the upper end of the leveling plate 1, and a slot 27 is provided on each moving seat 4. The left and right ends of the bending plate 26 are respectively connected to the slots 27 on the corresponding moving seats 4. To ensure the firmness of the connection, the moving seats 4 are also connected with locking bolts 28 for locking the bending plate 26 in the slots 27. The structural design of the bending plate 26 combined with the slots 27 enables the leveling plate 1 to be firmly and reliably connected between the two moving seats 4, and no displacement deviation will occur during the movement. The presence of the locking bolts 28 further increases the reliability of the connection. At the same time, this connection method also facilitates assembly and disassembly, which is conducive to the replacement and maintenance of the leveling plate 1.

[0040] In this embodiment, the sawtooth portion 5 has a sawtooth angle of 30°, a sawtooth spacing of 5-10 mm, and a sawtooth length of 5-10 mm.

[0041] The serrated portion 5 of the leveling device has optimized parameter design: the serrated angle is 30°, the serrated spacing is 5-10mm, and the serrated length is 5-10mm. The selection of these parameters enables the serrated portion 5 to exert appropriate pushing force on the road surface during the leveling process, flattening the protrusions and filling the recesses. The size of the serrated teeth is conducive to achieving a good leveling effect and avoiding material loss due to excessive cutting.

[0042] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
