Description

Technical Field

[0001] The utility model belongs to the technical field of highway infrastructure, and in particular relates to a portable road surface leveling device for highway construction. Background Art

[0002] During highway construction, ensuring pavement smoothness is crucial for improving road quality and extending its service life. Traditional pavement smoothing methods rely primarily on manual labor or simple mechanical equipment, the most common of which is the use of rollers. These rollers are typically cylindrical in design and work by compacting and smoothing materials like concrete through their own weight and the pressure they exert on the road surface during rolling.

[0003] However, existing pressure rollers have some shortcomings. First, due to their fixed weight, when faced with different types of road surfaces or construction under different load requirements, a pressure roller of a single weight is difficult to meet diverse needs, which may lead to problems such as over-pressure or insufficient compaction of the road surface, thereby affecting the quality of the road surface. Secondly, the material of the pressure roller is usually fixed. When faced with different temperature environments, a single material may not provide an ideal flattening effect. For example, in a high temperature environment, certain materials may affect the working performance of the pressure roller due to thermal expansion and contraction; in a low temperature environment, the hardness of the pressure roller may increase, causing unnecessary damage to the concrete surface.

[0004] Therefore, it is particularly important to develop a portable road-leveling device that can adjust its weight according to actual needs and select the appropriate material for different temperature environments. Such a device can not only improve construction efficiency but also ensure the ideal road leveling effect under various conditions, thereby better serving the highway construction industry.

[0025] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0026] Example 1:

[0027] See also Figure 1-Figure 5 As shown, a portable road leveling device for highway construction includes:

[0028] The bracket 1, the pushing roller 2, the pushing handle 3, and the mounting platform 4, the pushing roller 2 is rotatably mounted on the V-shaped connecting rod below the bracket 1, the pushing handle 3 is fixed to the top end of one side of the bracket 1, and the mounting platform 4 is fixed to the tail end of the other side of the bracket 1. Both ends of the mounting platform 4 are connected to the flattening component 6 through the connecting component 5;

[0029] The flattening assembly 6 includes a water storage pressure cylinder 61. Two rollers 62 are sleeved on the outer wall of the water storage pressure cylinder 61. The two rollers 62 are symmetrically arranged and nested in a concave and convex manner. Both side walls of the water storage pressure cylinder 61 are fixedly connected and communicated with support sleeves 63. The outer walls of the two support sleeves 63 are sleeved with rotating bearings 64. The rotating bearings 64 include an inner ring and an outer ring. The inner ring is fixedly connected to the threaded side wall of the water storage pressure cylinder 61 by multiple bolts, and the outer ring is fixedly connected to the threaded side walls of the two rollers 62 by multiple bolts.

[0030] A water injection hole 7 is provided on the supporting sleeve 63 , and a matching water injection cover 8 is installed on the water injection hole 7 .

[0031] Furthermore, a layer of epoxy resin coating is applied on the inner walls of the water storage pressure cylinder 61 and the support sleeve 63 to prevent water from corroding the inner walls of the water storage pressure cylinder 61 and the support sleeve. It can form a hard protective film to prevent moisture from penetrating and play an anti-corrosion role on the metal surface, and it is adaptable to various operating temperatures.

[0032] As can be seen from the above, when compacting and leveling the road surface, first use the push handle 3 to push the bracket 1, drive the push roller 2 to roll, and then fix the flattening component 6 to the mounting platform 4 through the connecting component 5. The rolling of the push roller 2 drives the flattening component 6 to perform the leveling work;

[0033] The flattening assembly 6 includes a water storage pressure cylinder 61 and a roller 62 sleeved on the water storage pressure cylinder 61. The roller 62 is rotated and sleeved on the outer wall of the water storage pressure cylinder 61, which can reduce the wear of the water storage pressure cylinder 61. During long-term use, the water pressure roller directly contacts with various materials of different hardness such as the road surface and is easily worn. At the same time, the roller 62 of different materials, hardness or texture can be replaced according to different types of road surfaces, and the compaction performance of the flattening device can be adjusted to better meet the compaction requirements of various road surfaces. Finally, the entire roller 62 structure is composed of two concave and convex nested and clamped rollers 62, which makes the roller 62 as a whole relatively easy to disassemble and carry. The detachability of the roller 62 can make it more convenient to clean the roller 62, simplifying the maintenance work of the flattening device.

[0034] According to the type of road surface and its required construction load requirements, the water injection cover 8 is opened, and the required amount of water is injected into the water storage pressure cylinder 61 through the water injection hole 7. According to the environment and road surface characteristics, water of suitable temperature is selected for injection, so that the water storage pressure cylinder 61 reaches the required leveling weight. The water injection cover 8 is closed, and the support sleeve 63 is pushed forward through the connecting component 5. By rotating the bearing 64, the water storage pressure cylinder 61 can be kept stationary while the roller 62 rotates relatively. Therefore, when the water storage pressure cylinder 61 is driven forward by the support sleeve 63, the roller 62 will continue to roll forward / backward. The water storage pressure cylinder 61 does not rotate due to the influence of gravity. The road surface leveling work is completed by the overall weight of the flattening component 6.

[0035] The method of changing the weight of the device by injecting water is chosen. On the one hand, because water has a high specific heat capacity, this not only helps to prevent the concrete from losing its viscosity due to temperature increase in high temperature environments, but also avoids the problem of premature solidification of concrete under low temperature conditions, thereby ensuring the quality of flattening, allowing the device to work under various climatic conditions, and improving the flexibility and efficiency of construction. On the other hand, by adjusting the amount of water injected into the water storage pressure cylinder 61, the internal pressure level can be easily adjusted, which means that the pressure can be customized according to the needs of highway projects of different scales and thicknesses to achieve the best compaction effect. This adjustability enables the device to perform well in different construction environments, ensuring the high-quality completion of road construction projects.

[0036] Specifically, regarding the above-mentioned connection component 5, refer to Figure 3 and Figure 4 As shown, the connecting assembly 5 includes two first screws 51 and two second screws 52. The two first screws 51 are respectively fixed on the two ends of the mounting platform 4, and the two second screws 52 are respectively fixed on the side walls on the opposite sides of the two support sleeves 63. The first screw 51 and the second screw 52 located on the same side are sleeved and connected with the same connecting arm 53, and are both fixedly connected to the connecting arm 53 by a locking nut 54.

[0037] As can be seen from the above, after adjusting the flattening assembly 6 to a suitable state in advance, the two ends of the connecting arm 53 are respectively put on the first screw 51 and the second screw 52, ​​and then the flattening assembly 6 and the mounting platform 4 are firmly fixed by the locking nut 54, and then the operation is carried out. When the operation is completed and the device needs to be cleaned or the device is recovered and taken back to the vehicle, the locking nut 54 is removed, the connecting arm 53 is removed, and the flattening assembly 6 is removed separately for subsequent processing.

[0038] Specifically, regarding the second screw 52, ​​refer to Figure 4 and Figure 5 As shown, the second screw rod 52 is sleeved with a support arm 13 on the opposite side. The support arm 13 is fixed to the second screw rod 52 through a nut thread. At the same time, a threaded hole is opened at the front end of the support arm 13 and is threadedly connected to a push bucket 14 through a bolt.

[0039] As can be seen from the above, the support arm 13 is placed on the second screw 52, ​​and the support arm 13 is rotated to a suitable angle according to the required leveling height of the leveling bucket 14, and then locked by the locking nut 54, and finally fixed by the bolt. Through this assembly method, the detachability of the device is achieved, which improves the portability of the device. At the same time, the setting of the leveling bucket 14 can help remove excess material and roughly level the surface, creating a more uniform surface for subsequent compaction, reducing the number of compactions and reducing equipment wear.

[0040] Specifically, regarding the above-mentioned mounting platform 4, refer to Figure 5 As shown, a cleaning blade 15 is fixedly connected to the front side wall of the mounting platform 4 , and the arc-shaped surface of the cleaning blade 15 fits the outer wall of the roller 62 .

[0041] As can be seen from the above, during the compaction process, the roller may be stuck with mud, asphalt or other materials. The cleaning scraper 15 can help remove these attachments, keep the roller surface clean, and then improve the road smoothing effect.

[0042] Example 2:

[0043] refer to Figure 4 and Figure 5 As shown, a water supply bucket 9 is fixedly connected to the top surface of the mounting platform 4, a water supply hole is opened on the top surface of the water supply bucket 9, and a plug 10 adapted thereto is installed in the water supply hole, and water supply pipes 11 are connected to both sides of the water supply bucket 9, and the other ends of the two water supply pipes 11 are connected to the supporting sleeve 63, and a water stop valve 12 is installed in the middle of the two water supply pipes 11.

[0044] As can be seen from the above, the water replenishment bucket 9 serves as a supplementary device for the external water source. When the water in the water storage pressure cylinder 61 is reduced due to evaporation or other reasons, it can open the water stop valve 12 and use the water replenishment pipe 11 to replenish water into the interior. This design enables the water storage pressure cylinder 61 to be replenished with water in a timely manner, effectively preventing the problem of insufficient water caused by evaporation of the internal water source, thereby ensuring the quality and efficiency of the leveling operation. At the same time, a stable water supply also helps to improve the quality of the working surface, ensuring that the compacted road surface has uniform density and flatness, and meets the requirements of engineering specifications.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
