Description

Technical Field

[0001] This utility model specifically relates to a road surface vibratory leveling device for municipal road construction, belonging to the field of road surface vibratory leveling technology. Background Technology

[0002] Road surface leveling is a crucial step in municipal road construction, directly affecting road smoothness, load-bearing capacity, and service life. Through leveling operations, concrete materials can be made uniform and dense, eliminating unevenness generated during paving and ensuring that the road has good driving comfort and safety.

[0003] However, in current municipal road construction, although the road surface is initially cleaned before paving, it is still difficult to completely eliminate the presence of large stones or aggregated gravel. If these stones are not effectively removed before leveling, they will be forcibly embedded into the road surface material due to the vibration and pressure of the leveling device during the leveling process. This not only makes it difficult for the leveling device to compact the road surface evenly, resulting in local bumps and damaging the road surface smoothness, but also affects the density of the road surface material, reducing the overall strength and durability of the road surface.

[0004] To address the above problems, this application proposes a road surface vibratory leveling device for municipal road construction. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a road surface vibratory leveling device for municipal road construction. During road surface vibratory leveling, the height of the inclined teeth is adjusted by an adjustment plate. The frame moves, causing the inclined teeth to remove protruding stones from the road surface and guide them into a debris inlet. A barrier rod inside the debris inlet intercepts the stones while allowing road surface material to pass through. Subsequently, a pre-compression roller performs initial compaction, the vibratory leveling assembly vibrates and flattens the surface, and a subsequent flattening roller performs secondary compaction, significantly improving the road surface smoothness and solving the problems mentioned in the background art.

[0006] A road surface vibratory leveling device for municipal road construction includes: a frame, on which a vibratory leveling mechanism is provided, and the vibratory leveling mechanism includes a vibratory leveling component and an auxiliary component; the vibratory leveling component includes a liftable and adjustable lifting plate, a vibrating plate is connected to the lower part of the lifting plate by a spring, and a vibrating motor is installed on the vibrating plate, which vibrates to vibrate the road surface for vibratory leveling construction; the auxiliary component includes a pre-leveling roller and a pressing roller that are rotatable and installed on the front and rear sides of the frame, the front end of the frame is provided with a liftable height adjustment plate, and the bottom of the height adjustment plate is provided with multiple sets of helical teeth, and a debris opening is provided below the height adjustment plate, and multiple sets of blocking rods for blocking debris are installed at intervals inside the debris opening.

[0007] Furthermore, a fixing rod is installed on the lifting plate, and a first lead screw is threadedly connected to the top of the fixing rod. A drive motor is installed on the top of the frame, and the output shaft of the drive motor is connected to the first lead screw.

[0008] Furthermore, a set of first guide rods is installed on each of the two sides above the lifting plate, and the upper end of the first guide rods penetrates through the frame.

[0009] Furthermore, the vibration motor is provided in two sets, and the spring is provided in four sets, with the four sets of springs located at the four corners below the lifting plate.

[0010] Furthermore, a set of inclined scrapers is provided on one side below the flattening roller and the pre-flattening roller, and the upper end of the scraper is fixedly connected to the frame.

[0011] Furthermore, a set of second guide rods is provided on both sides of the height adjustment plate. The lower end of the second guide rod is fixedly connected to the frame, and its upper end passes through the height adjustment plate.

[0012] Furthermore, a second lead screw is threadedly connected to the middle of the upper part of the height adjustment plate, and a rocker wheel is installed at the upper end of the second lead screw, with its lower end rotatably connected to the frame.

[0013] Furthermore, the upper surface of the helical teeth is an inclined surface, and multiple sets of helical teeth are distributed at intervals.

[0014] Furthermore, a pusher is installed at the rear of the frame.

[0015] Beneficial effects:

[0016] 1. By designing the vibratory leveling component, when the lifting plate lowers the vibratory plate to contact the road surface, the vibratory motor generates vertical vibration, and the vibration force is evenly transmitted to the road surface through the vibratory plate. During this process, the springs between the vibratory plate and the lifting plate undergo synchronous elastic deformation, which not only absorbs part of the reverse impact force, but also concentrates the vibration energy on the road surface through elastic restoring force, forming an energy transmission cycle of vibration, buffering, and re-vibration, significantly improving the leveling effect.

[0017] 2. By designing auxiliary components, during road surface leveling, the height adjustment plate lowers the inclined teeth to maintain a suitable working height with the road surface. As the frame moves along the construction direction, the inclined teeth advance synchronously, using the inclined surface to remove protruding stones from the road surface and guide the stones to slide into the debris inlet along the slope. The barrier bars inside the debris inlet are arranged at intervals, which can effectively prevent stones from remaining inside while ensuring that road material can pass smoothly through the gaps between the bars. Then, the pre-compression roller initially compacts the road surface after the stones are removed. After the leveling component achieves flatness through vibration, the pressing roller located behind the leveling component rolls to perform secondary compaction of the road surface. Through the integrated process of "removal-pre-compression-leveling-final compaction", the flatness and density of the road surface are significantly improved. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 As shown, a road surface vibrating and leveling device for municipal road construction includes: a frame 1, on which a vibrating and leveling mechanism is provided, and the vibrating and leveling mechanism includes a vibrating and leveling component 2 and an auxiliary component 3; the vibrating and leveling component 2 includes a lifting plate 23 that can be raised and lowered, and a vibrating plate 21 is connected to the lower part of the lifting plate 23 by a spring 22, and a vibrating motor 28 is installed on the vibrating plate 21, which vibrates the vibrating plate 21 to vibrate and level the road surface; the auxiliary component 3 includes a pre-leveling roller 32 and a pressing roller 31 that can be rotated on the front and rear sides of the frame 1, and a lifting and leveling plate 33 is provided at the front end of the frame 1, and multiple sets of helical teeth 37 are installed at the bottom of the lifting and leveling plate 33. A debris opening 38 is opened below the lifting and leveling plate 33, and multiple sets of blocking rods 39 for blocking debris are installed at intervals inside the debris opening 38.

[0026] Please see Figures 1-2 As shown, a fixing rod 27 is installed on the lifting plate 23, and a first lead screw 26 is threadedly connected to the top of the fixing rod 27. A drive motor 25 is installed on the top of the frame 1, and the output shaft of the drive motor 25 is connected to the first lead screw 26.

[0027] Please see Figures 1-2 As shown, a set of first guide rods 24 are installed on both sides above the lifting plate 23, and the upper end of the first guide rods 24 penetrates through the frame 1.

[0028] Please see Figure 3 As shown, there are two sets of vibration motors 28 and four sets of springs 22. The four sets of springs 22 are located at the four corners below the lifting plate 23. The vibration motor 28 generates vertical vibration, and the vibration force is transmitted to the road surface through the vibration plate 21, thereby realizing vibration leveling construction.

[0029] Please see Figure 5 As shown, a set of inclined scraper plates 310 are respectively provided on one side below the flattening roller 31 and the pre-flattening roller 32, and the upper end of the scraper plate 310 is fixedly connected to the frame 1. While the flattening roller 31 and the pre-flattening roller 32 are rolling, the scraper plate 310 can scrape off the excessively thick debris attached to the surface of both, so as to avoid the excessive debris from affecting the flattening effect.

[0030] Please see Figures 1-2 As shown, a set of second guide rods 34 are provided on both sides of the height adjustment plate 33. The lower end of the second guide rod 34 is fixedly connected to the frame 1, and its upper end passes through the height adjustment plate 33.

[0031] Please see Figures 1-2 As shown, a second lead screw 35 is threadedly connected to the middle of the upper part of the height adjustment plate 33, and a rocker wheel 36 is installed at the upper end of the second lead screw 35. Its lower end is rotatably connected to the frame 1. The rocker wheel 36 can drive the second lead screw 35 to rotate, which in turn can drive the height adjustment plate 33 to rise and fall to adjust the height.

[0032] Please see Figure 1 and Figure 4 As shown, the upper surface of the helical tooth 37 is an inclined surface, and multiple sets of helical teeth 37 are distributed at intervals.

[0033] Please see Figures 1-2 As shown, a pusher 4 is installed at the rear of the frame 1, which can push the frame 1.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] During municipal road construction, the second lead screw 35 is first driven to rotate by rotating the rocker wheel 36, causing the height adjustment plate 33 to rise and fall along the path defined by the second guide rod 34, which in turn drives the inclined tooth 37 to descend to the appropriate working height. The frame 1 is then pushed by the pusher 4, and the frame 1 can move along the construction direction via the flattening roller 31 and the pre-flattening roller 32. During the movement, the inclined surface of the inclined tooth 37 removes protruding stones from the road surface and guides the stones along the inclined surface into the debris opening 38. The barrier rod 39 in the debris opening 38 blocks the stones while allowing road materials to pass through. Subsequently, the pre-flattening roller 32 performs preliminary compaction on the road surface after the stones have been removed.

[0036] During the vibratory leveling process, the drive motor 25 drives the first lead screw 26 to rotate within the fixed rod 27. Through threaded transmission, the lifting plate 23 drives the first guide rod 24 to rise and fall along the vertical path. Then, the lifting plate 23 drives the vibrating plate 21 to descend until it is in contact with the road surface. The vibrating motor 28 is started to generate vertical vibration. The vibration force is transmitted to the road surface through the vibrating plate 21. The spring 22 between the vibrating plate 21 and the lifting plate 23 undergoes elastic deformation, absorbing the reverse impact force and forming an energy transmission cycle of vibration, buffering, and re-vibration through elastic restoring force, thus leveling the road surface. Finally, the pressing roller 31 located behind the vibratory leveling component 2 rolls to perform secondary compaction on the leveled road surface. Through the integrated process of "removal-pre-compaction-vibratory leveling-final compaction", efficient vibratory leveling operation is achieved. After the vibratory leveling is completed, subsequent scraping and finishing operations can be carried out on the road surface to make the road surface flat and smooth.
