Description

Technical Field

[0001] The present application relates to the technical field of road pavement maintenance devices, and in particular to a road pavement rapid paving maintenance device and method. Background Art

[0002] In the field of road construction, laying asphalt is a key step in building a smooth and durable road surface. This link is crucial to improving the overall quality of the road and extending its service life. However, as the road is put into use, external forces such as vehicle loads, climate factors, and time accumulation effects will cause various forms of damage to the asphalt pavement, among which surface bulges are a common disease phenomenon. These bulges not only destroy the visual beauty of the road, but also potentially threaten driving safety and reduce driving stability and comfort. Therefore, timely and effective maintenance measures are particularly important.

[0003] In response to the problem of asphalt pavement bulges, a variety of maintenance devices have been developed in the prior art, such as the utility model patent with publication number CN216193857U, which introduces a highway road engineering asphalt rapid paving maintenance device. The device integrates a flattening block and a vibration function, which can respond quickly when a road bulge is detected, and effectively flatten the raised part by using the downward pressure and vibration of the flattening block. It is particularly worth mentioning that the design also cleverly combines a heating mechanism, which further enhances the flattening effect by heating and softening the asphalt pavement, ensuring the flatness of the repair area and good integration with the original pavement.

[0004] Since the asphalt pavement is heated and softened during the flattening process, some asphalt material is often left on the bottom of the flattening block after the flattening operation is completed. If these residues are not cleaned up in time, they will not only affect the efficiency of subsequent maintenance operations, but may also be difficult to remove due to hardening. In the long run, they may cause wear and tear on the flattening block, increase maintenance costs, and also bring unnecessary troubles to the operation of road maintenance personnel. There is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a road surface rapid paving and maintenance device and method to solve the problem of low efficiency in cleaning residual asphalt impurities adhered to the flattening block in the above-mentioned related technologies.

[0006] In the first aspect, the present application provides a road surface rapid paving and maintenance device that adopts the following technical solution: The cam is provided with a plurality of support rods, each of which is provided with a plurality of support rods, each of which is provided with a plurality of support rods, each of which is provided with a plurality of support rods.

[0007] By adopting the above technical solution, the scraper and the power part are cleverly combined, so that after the flattening operation is completed, when the flattening plate moves up to a position flush with the upper edge of the scraper, the power part can be quickly started, driving the scraper to slide along the slide rail, effectively scraping off the asphalt material remaining on the bottom side of the flattening plate. This design not only simplifies the cleaning steps and reduces the workload of maintenance personnel, but also avoids the wear of the flattening block caused by the hardening of the residue, extending the service life of the device. At the same time, this technical solution ensures the efficient and continuous maintenance of the maintenance work, improves the overall work efficiency, and brings a more convenient and efficient maintenance solution to the road construction field.

[0008] Optionally, the power component includes a power motor fixed on the bottom side of the base plate, a power screw coaxially fixedly connected to a driving rod on the power motor, and the slider is provided with an adjustment screw hole for the power screw to be screwed into and pass through.

[0009] By adopting the above technical solution, the combination of the power motor and the power screw provides a stable and controllable power source for the sliding of the scraper. When the power motor is running, its driving rod drives the power screw to rotate. Since the slider is provided with an adjustment screw hole that matches the power screw, the rotation of the power screw can be converted into a linear sliding motion of the crossbar. This design is not only simple in structure and easy to implement, but also can accurately control the moving speed and position of the scraper, ensuring the uniformity and thoroughness of the cleaning of the bottom and side of the flat plate.

[0010] Optionally, support plates are provided on two opposite sides of the base plate, and a support rod with adjustable length is fixed on the lower side of the support plate, and the support rod can be adjusted to a state where its lower end is flush with the bottom side of the moving wheel.

[0011] By adopting the above technical solution, the support rod can be adjusted to a state where the lower end is flush with the bottom side of the moving wheel. This design not only ensures a smooth transition of the device between the working state and the non-working state, but also enables the device to quickly retract the support rod when it needs to be moved to restore the supporting function of the moving wheel, thereby improving the portability and flexibility of the device.

[0012] Optionally, the support rod and the base plate are rotationally connected at the side edges close to each other, and a locking member for fixing the rotation state of the support plate is provided above the base plate, and the support rod can rotate upward with the support plate to a vertically upward state.

[0013] By adopting the above technical solution, the rotational connection design between the support rod and the edge of the base plate, combined with the fixing function of the locking piece, enables the support rod to flexibly switch between two states: vertically supporting the device downward and vertically retracting upward. This design not only saves space occupied by the device when the support rod is not used for support, but also facilitates the rapid deployment of the support rod for support when needed, thereby improving the efficiency and convenience of the device.

[0014] Optionally, a protective curtain is provided above the base plate, hooks are fixedly provided at the four corners of the protective curtain, and a clamping ring is fixedly provided on the outer edge of the end of the support rod away from the support plate; the four hooks are respectively inserted into the corresponding clamping rings when the support rod is in a vertical upward state.

[0015] By adopting the above technical solution, the setting of the protective curtain, combined with the clamping and fixing method of the hooks on the four corners and the clamping rings at the ends of the support rods, can provide effective shielding protection (sun protection and rain protection) for the upper part of the device when the support rod is in a vertical upward state. This can not only prevent operators from being accidentally injured by upper components during maintenance, but also reduce the interference of external factors on key components such as driving parts and flattening blocks, ensuring the smooth progress of maintenance operations. At the same time, the quick clamping design of the hooks and the clamping rings makes the installation and removal process of the protective curtain simple and quick, and improves the convenience and flexibility of the device.

[0016] Optionally, the handle is tilted and fixed on the upper edge of the base plate, a fixed sleeve is slidably provided on the outer periphery of the two tilted rods on the handle, and the handle is provided with a fastener for locking the fixed sleeve by sliding up and down; a storage box for storing the protective curtain is provided above the base plate, and the two ends of the storage box are respectively fixedly connected to the side surfaces of the two fixed sleeves close to each other, the upper side surface of the storage box is a storage opening, and a cover plate is hinged on the upper edge of the storage box.

[0017] By adopting the above technical solution, the inclined design of the handle and the sliding locking function of the fixed sleeve allow the operator to flexibly adjust the height of the storage box according to personal height and work requirements; the hinged setting of the cover plate makes it easy for the operator to quickly open or close the storage opening when needed, thereby realizing the rapid access and storage of the protective curtain.

[0018] Optionally, two limiting notches are provided on the side of the storage box facing the driving member; when the support rod is in a vertically upward state, the two support rods close to the handle can be inserted into the limiting notches after the storage box is slid downward and adjusted.

[0019] By adopting the above technical solution, the limiting notch on the side of the storage box cooperates with the clamping when the support rod is in the vertical upward state, so that the support rod can be effectively fixed and stored when not in use, avoiding the problem of the support rod swinging at will or occupying extra space. This design not only makes the overall structure of the device more compact, convenient for storage and transportation, but also improves space utilization, making the operation area more tidy and orderly.

[0020] Optionally, an extension plate parallel to the support rod is fixed on the side edge of the support plate away from the support rod, and the extension plate and the support rod are fixed on the same side of the support plate; a first screw hole is provided on the vertical side of the base plate, and a first through hole is provided on the extension plate, which coincides with the first screw hole when the support rod is in a vertical downward state; a second through hole is provided on the support plate, and a second screw hole is provided on the upper side of the base plate, which coincides with the second through hole when the support rod is in a vertical upward state; the locking piece is a locking bolt that passes through the first through hole and then is screwed into the first screw hole, and passes through the second through hole and then is screwed into the second screw hole.

[0021] By adopting the above technical solution, the support rod is firmly locked in the vertical downward supporting state and the vertical upward retracted state, which prevents the support rod from rotating or loosening due to unexpected factors, and ensures the stability and safety of the device in different use states. At the same time, the design of the first through hole, the second through hole, the first screw hole and the second screw hole allows the locking bolt to be easily inserted and locked, which is easy and quick to operate, and improves the adjustment flexibility and practicality of the device.

[0022] Optionally, a connecting plate is fixedly provided on the sides of the two sliders away from each other, and a vertically upward limiting plate is vertically fixedly provided on the end of the connecting plate away from the slider; when the support rod is in a vertically downward state, the side of the limiting plate toward the slider can slide with the cross bar to a state of abutting against the side of the extension plate toward the support rod.

[0023] By adopting the above technical solution, when the support rod is needed to support the maintenance device, the support rod is first flipped downward with the support plate, and then the side of the limit plate facing the slider can slide with the cross bar to abut the side of the extension plate facing the support rod, so that the limit plate is used to pre-lock the support rod in this state, which is convenient for further fixing the extension plate in this state with the locking bolt; this design not only provides an accurate positioning reference for the subsequent locking bolt fixing, but also effectively prevents the support rod from accidentally rotating or shifting during the fixing process, thereby improving the stability of the support. At the same time, the pre-locking operation is simple and quick, without the need for additional tools or steps, further improving the convenience and practicality of the device.

[0024] In the second aspect, the present application provides a method for rapid pavement maintenance using the following technical solutions: A method for rapid pavement paving and maintenance, using any one of the rapid pavement paving and maintenance devices described above, comprises the following steps: Step 1: Move the maintenance device to the top of the road surface to be maintained, then rotate the support rod with the support plate downward to a vertical state and fix it, and then adjust the length of the support rod so that the lower end of the support rod abuts against the road surface; Step 3: Start the driving member to drive the flattening block to move downward, and the flattening plate first heats the road surface and then flattens the road surface; Step 4: After the road surface maintenance is completed, the driving member drives the hole pressing block and the pressing plate to move upward and reset, and then the power member drives the scraper to slide to clean the lower side of the pressing plate; Step 5: Rotate the support rod upward with the support plate to a vertical position and secure it.

[0025] By adopting the above technical solution, the method makes full use of the various functions of the maintenance device, including the flexible adjustment of the support rod, the heating and flattening effect of the flattening plate, and the effective cleaning of the scraper, etc., to ensure the quality and efficiency of road maintenance. At the same time, the steps are clear and the operation is simple, so that the operator can quickly master and perform it skillfully, improving the overall fluency and consistency of the operation.

[0026] In summary, this application includes the following beneficial technical effects: After the flattening operation is completed, when the flattening plate moves up to a position flush with the upper edge of the scraper, the power part can be quickly started to drive the scraper to slide along the slide rail, effectively scraping off the residual asphalt material on the bottom side of the flattening plate. This design not only simplifies the cleaning steps and reduces the workload of maintenance personnel, but also avoids the wear of the flattening block caused by the hardening of the residue, thus extending the service life of the device.
