Description

Technical Field

[0001] This application belongs to the field of road maintenance, and in particular relates to a road maintenance device. Background Technology

[0002] Potholes are a common traffic hazard in urban and rural road networks (mostly asphalt roads). These roads are not only uneven but also often accompanied by water accumulation, especially during the rainy season. Potholes are characterized by their irregular terrain and unpredictable depth, while water accumulation further exacerbates their danger. For vehicles, potholes and water pose a double threat: on the one hand, vehicles may be unable to avoid them and fall into the potholes, resulting in chassis damage or suspension system failure; on the other hand, water may obscure the true depth of the potholes, making it difficult for drivers to judge and increasing the risk of accidents.

[0003] Potholes in road surfaces often result from a variety of factors, such as prolonged exposure to heavy vehicle traffic, unstable soil, and poor drainage systems. Once formed, repair work becomes extremely complex. To ensure construction safety, the repair area is usually fenced off to prevent passing vehicles and pedestrians from accidentally entering. Next, repair personnel will manually drain the water from the potholes, followed by backfilling and compaction. The entire process is time-consuming and labor-intensive, demonstrating that existing technologies need further improvement. Utility Model Content

[0004] This invention provides a road maintenance device to at least solve or alleviate one or more technical problems in the prior art, or to at least provide a beneficial alternative.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A road maintenance device includes a vehicle body, which integrates a water pumping module, a filler module, and a compaction module.

[0007] The pumping module includes pumping pipes, a pump, and a storage tank, which can quickly pump out water from depressions.

[0008] The filling module includes a storage tank with its outlet located at the bottom of the vehicle body. A first vision sensor is installed at the bottom of the vehicle body to enable operators to monitor the condition under the vehicle body for accurate delivery of repair materials.

[0009] The compaction module includes a compactor and a lifting mechanism. The lifting mechanism can drive the compactor to compact the fill material. The three modules work together to improve the efficiency of repairing and maintaining potholes.

[0010] In the above structure, the three modules of pumping, filling, and ramming are integrated into the same vehicle body, realizing an integrated operation process from water extraction to material filling and then to ramming. This greatly shortens the operation cycle and improves the overall repair efficiency. Workers only need to drive the device to the pothole location to quickly start the operation. There is no need to carry a variety of tools and equipment, reducing the preparation time. A first visual sensor is configured at the bottom of the vehicle body of the filling module, enabling the operator to monitor the situation under the vehicle in real time and ensuring the accurate placement of the repair material. This not only improves the repair quality but also reduces material waste. The pumping module can quickly extract the accumulated water in the pothole, providing a dry working environment for subsequent filling and ramming operations. This helps to ensure the tight bonding of the repair material with the pothole road surface and improves the durability of the repair. The ramming module drives the ramming component to act through a lifting mechanism to fully ram the filling material. This helps to improve the flatness and compaction degree of the repaired road surface, ensuring that the repair effect is consistent with the surrounding road surface. The device integrates multiple functional modules, realizing mechanized operation. This greatly reduces the dependence on human resources, reduces labor costs, and mechanized operation reduces the risk of manual operation and improves the safety of the operation.

[0011] In a preferred implementation, the ramming module is arranged at the front side or the rear side of the vehicle head. The lifting mechanism of the ramming module is connected to a swing adjustment device to increase the operation coverage area of the ramming component.

[0012] Since the shapes and sizes of pothole road surfaces often vary. And the ramming component may not cover some potholes. By adjusting the swing adjustment device, the ramming component can adjust its position to ensure that every corner of the pothole is fully rammed. Moreover, swing ramming can ensure the uniform distribution of the repair material in the pothole, avoiding the situation of local looseness or over-ramming. And since the ramming component can cover a wider area, the number of times the vehicle needs to repeatedly adjust its position for operation can be reduced. This helps to shorten the construction cycle and improve the overall construction efficiency.

[0013] In a preferred implementation, the swing adjustment device includes a swing beam. One end of the swing beam is connected to the lifting mechanism, and the other end is fixedly connected to a rotating shaft. The rotating shaft is rotatably connected to a bracket on the front side or the rear side of the vehicle head, and the rotating shaft is driven to rotate by a driving motor.

[0014] In a preferred implementation, the cross-section of the bracket is in a "U" shape to enable the swing beam to rotate 180°.

[0015] In a preferred implementation, a second visual sensor is configured on the front side or the rear side of the vehicle head to enable the operator to monitor the situation in front of or behind the vehicle to facilitate the accurate ramming of the repair material.

[0016] In a preferred implementation, the bracket and the discharge port of the storage tank are arranged in the same line. The second vision sensor is located on the upper side of the bracket. By monitoring the relative position of the bracket and the pitted area on the ground, the vehicle can be adjusted so that the discharge port corresponds to the pitted area on the ground.

[0017] In a preferred embodiment, the water tank is located on the underside of the vehicle's front or the underside of the vehicle body, and the free end of the water pumping pipe extends to the front of the vehicle or the rear of the vehicle body and is detachably fixed to the swing beam.

[0018] In a preferred embodiment, the storage tank stores asphalt material and is equipped with a stirring device. The stirring device continuously and uniformly stirs the material in the tank to ensure that the material maintains suitable fluidity and uniformity.

[0019] In a preferred embodiment, the storage tank is equipped with a heating pipe to heat the asphalt material inside the storage tank, so that the asphalt aggregate maintains a suitable temperature during paving and ensures the quality of the road repair.

[0020] In a preferred implementation, the lifting mechanism is a hydraulic cylinder. Attached Figure Description

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0031] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0032] The present invention will now be described with reference to the accompanying drawings.

[0033] The specific solution adopted is as follows:

[0034] like Figure 1-4 As shown, this utility model provides a road maintenance device, including a vehicle body, which integrates a water pumping module, a filler module, and a compaction module.

[0035] The pumping module includes a pumping pipe 10, a pumping pump, and a water storage tank 11, which can quickly pump out water from depressions.

[0036] The filling module includes a storage tank 12, whose outlet 120 is located at the bottom of the vehicle body 21. A first vision sensor is installed at the bottom of the vehicle body 21 so that the operator can monitor the condition under the vehicle to accurately deliver the repair material.

[0037] The compaction module includes a compactor 13 and a lifting mechanism 14. The lifting mechanism 14 can drive the compactor 13 to compact the fill material. The three modules work together to improve the efficiency of repairing and maintaining potholes.

[0038] By employing the road maintenance device of this application, the pumping module, through a combination of pumping pipes, a pump, and a water storage tank 11, can quickly remove accumulated water from depressions, creating a dry working environment for subsequent filling and compaction work. The filling module is equipped with a storage tank 12 and a first-person vision sensor, allowing operators to accurately dispense repair materials by monitoring the underside of the vehicle. This not only reduces material waste but also ensures the uniform distribution of repair materials, laying a good foundation for compaction work. The compaction module, through a lifting mechanism 14, drives the compaction component 13 to effectively compact the filling material, ensuring a solid and flat road surface after repair. This mechanized compaction method is more efficient and uniform than manual compaction. The three modules are integrated into the vehicle body for collaborative operation, forming a complete repair process, improving overall construction efficiency, reducing the degree of manual intervention, and allowing workers to primarily sit in the vehicle. Warning lights and signs can be installed on the vehicle to alert other road users, reducing the risk of construction workers working under open roads and improving construction safety.

[0039] As a preferred embodiment of this application, the compaction module is located on the front side of the vehicle head 20 or the rear side of the vehicle body 21. The lifting mechanism 14 of the compaction module is connected to the swing adjustment device to increase the working coverage of the compaction component 13.

[0040] The swing adjustment device allows the compactor 13 to swing at a certain angle in the horizontal plane. The compactor 13 can not only perform compaction work in the vertical direction but also cover a wider area in the horizontal direction. Since potholes often vary in shape and size, and the compactor 13 may not be able to cover all potholes, adjusting the swing adjustment device allows the compactor 13 to be repositioned, ensuring that every corner of the pothole is adequately compacted. Furthermore, swing compaction ensures that the repair material is evenly distributed within the pothole, avoiding localized loosening or over-compaction. Because the compactor 13 can cover a wider area, it reduces the number of times the vehicle needs to be repositioned for operation. This helps to shorten the construction cycle and improve overall construction efficiency.

[0041] See Figure 1, the swing adjustment device includes a swing beam 15. One end of the swing beam 15 is connected to a lifting mechanism 14. The lifting mechanism 14 is a hydraulic cylinder, which can bear a large weight and provide a strong lifting force. The lifting mechanism 14 ensures the movement and positioning of the ramming member 13 in the vertical direction. The ramming member 13 can be lifted to different heights as needed. The other end of the swing beam 15 is rotatably connected to a bracket 18 on the front side of the vehicle head 20 or the rear side of the vehicle body 21 through a rotating shaft 16, allowing the swing beam 15 to swing at a certain angle in the horizontal plane, thereby expanding the operation coverage area of the ramming member 13. The rotating shaft 16 is driven to rotate by a driving motor 17, realizing the automatic swing of the swing beam 15. Using a reduction motor as the driving motor 17 can ensure that the swing beam 15 has sufficient torque and stability during the swing. Workers can operate the reduction motor through a controller in the vehicle. The controller can accurately control the driving motor 17 to rotate forward, reverse, start or stop, realizing the swing adjustment of the swing beam 15. This application will not be elaborated on for the prior art.

[0042] To facilitate workers to see the situation of the ramming member 13 in the vehicle, a second vision sensor 19 is configured on the front side of the vehicle head 20 or the rear side of the vehicle body 21, so that the operator can monitor the situation in front of or behind the vehicle, facilitating the accurate ramming of the repair material. In this way, workers can work in a relatively safe and comfortable environment, avoiding the hardship and risks of working in a harsh environment for a long time.

[0043] See Figure 1 and Figure 2 , the cross-section of the bracket 18 is in a "U" shape, enabling the swing beam 15 to rotate 180°.

[0044] The design of the "U" - shaped bracket 18 allows the swing beam 15 to swing 180° in the horizontal plane. This large - range swing ability enables the ramming member 13 to cover a wider area. When the swing beam 15 is flush with the vehicle head 20, due to the design of the "U" - shaped bracket 18, the vehicle does not occupy a long space. This compact layout makes it more convenient for the maintenance device to travel and park on the road, reducing the impact on other traffic.

[0045] Furthermore, the bracket 18 is arranged collinearly with the discharge port 120 of the storage tank 12. The second vision sensor 19 is located above the bracket 18. By monitoring the relative position between the bracket 18 and the ground pothole area, the vehicle is adjusted to facilitate the discharge port 120 to correspond to the ground pothole area.

[0046] Through real-time monitoring by the second vision sensor 19, workers can clearly see the relative position of the support 18 to the pothole area on the ground. This allows workers to quickly and accurately adjust the vehicle position to ensure that the discharge port 120 directly aligns with the pothole area. When workers initially align the support 18 with the center of the pothole area, subsequent operations become much simpler. When filling is needed after pumping out the water, the vehicle only needs to drive in a straight line to align the discharge port 120 with the pothole area, without needing to adjust its position multiple times. Due to the rapid and accurate positioning, the entire construction process is accelerated. This helps to shorten the construction cycle and improve overall work efficiency.

[0047] As a preferred embodiment of this application, the water tank 11 is located on the lower side of the front of the vehicle 20 or the lower side of the vehicle body 21, and the free end of the water pumping pipe extends to the front of the front of the vehicle 20 or the rear of the vehicle body 21 and is detachably fixed to the swing beam 15.

[0048] The free end of the pumping pipe is detachably fixed to the swing beam 15. Clamps can be installed on the swing beam 15 as a detachable fixing method for the pumping pipe. Workers can quickly remove the pipe and place it in the pit when pumping is needed. After pumping is completed, the free end of the pipe can be re-fixed to the swing beam 15. Because the swing beam 15 has a swing-and-retrieve function, the pumping pipe will also retract when it swings to the retraction position, avoiding dragging and damage to the pipe on the ground. Since the pumping pipe can be quickly accessed and retrieved, workers do not need to spend a lot of time on pipe laying and retrieval. This greatly reduces working time and improves overall work efficiency.

[0049] In a preferred embodiment of this application, the storage tank 12 stores asphalt aggregate and is equipped with a mixing device 121. The mixing device 121 continuously and uniformly mixes the material in the tank to ensure that the material maintains suitable fluidity and uniformity. The continuous and uniform mixing by the mixing device 121 effectively prevents the asphalt aggregate from separating, settling, or solidifying due to prolonged standing. Through mixing, the material maintains suitable fluidity, facilitating subsequent construction operations. Simultaneously, the storage tank 12 is equipped with a heating pipe 122 to heat the asphalt aggregate inside, maintaining a suitable temperature during paving and ensuring the quality of the repaired road surface. A suitable temperature improves the paving effect and compaction of the asphalt aggregate, thereby enhancing the quality of the repaired road surface. The use of the heating pipe 122 ensures that the asphalt aggregate maintains the optimal working temperature during paving, helping to reduce road surface defects and extend the service life of the road surface.

[0050] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0051] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
