Description

Technical Field

[0001] This invention relates to the field of road paving technology, specifically to a paving device for road traffic pavement maintenance. Background Technology

[0002] Paving equipment for road traffic pavement maintenance is the core engineering equipment for road maintenance and repair operations. The whole machine integrates a power drive system, a hydraulic continuously variable transmission walking mechanism, a front-end receiving hopper, a scraper conveyor and spiral material distribution device, a screed assembly with heating and vibration functions, and an intelligent measurement and control system. In road surface milling and repaving, pothole repair, and hot recycling maintenance, it can evenly spread asphalt mixture or on-site recycled pavement materials to the base surface to be repaired. Through the vibration pre-compaction and hot leveling operation of the screed, the paving layer is shaped in one go. The mainstream models are equipped with automatic leveling and material level closed-loop control technology, which can accurately match different paving width and thickness requirements, effectively ensuring the flatness and uniformity of the paving layer, significantly improving the efficiency of road maintenance construction and the service durability of the repaired pavement.

[0003] However, the screed in existing paving equipment continuously generates vertical alternating reaction forces during operation. The screed is rigidly connected to the frame, and this excitation force is directly transmitted to the main frame, causing the whole machine to resonate. The frame vibration causes fluctuations and distortions in the data collected by the sensors, triggering frequent erroneous adjustments by the leveling system, ultimately resulting in uneven paving thickness and reduced smoothness. Furthermore, the asphalt mixture pile in front of the screed and in the auger distribution area is the feed buffer layer during the paving process. The top surface of the pile is prone to unevenness, and coarse aggregate at higher levels is likely to roll down the slope of the pile to lower levels or the paving edge, forming coarse and fine aggregate separation. At the same time, in areas with insufficient material level, the auger blades are exposed, and the material is excessively scattered by the blades, further aggravating the separation of coarse and fine aggregates. After paving, the fine aggregate separation area has low density and is prone to loosening and cracking, which is the core cause of early damage after road repair.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing paving equipment designed for road traffic and pavement maintenance. Summary of the Invention

[0007] Preferably, the shock absorption assembly includes a compression spring disposed between the fixed base and the ironing plate, a push plate is rotatably connected to the protrusion at the top of the ironing plate, a sliding ring is rotatably connected to one side of the push plate, a limit rod is slidably connected to the sliding ring, a buffer spring is fixed to one side of the sliding ring, and one end of the buffer spring is fixedly connected to the moving ring.

[0008] Preferably, the limiting rod is fixedly connected to the protrusion at the bottom of the fixed seat, the limiting rod is slidably connected to the sliding ring and the moving ring, and the buffer spring is sleeved on the outside of the limiting rod.

[0009] Preferably, the adjusting assembly includes a push rod disposed on one side of a fixed plate, a push block fixed on one side of the push rod, movable plates slidably connected to both sides of the push block, a movable plate fixedly connected to a movable ring on one side of the movable plate, and a first sliding rod fixed on one side of the push rod, the first sliding rod being slidably connected to a first oil tank.

[0010] Preferably, the first oil tank is fixedly connected to a protruding part on one side of the fixed plate, and the push rod is slidably connected to the protruding part.

[0011] Preferably, an electric telescopic rod is fixed to one side of the push rod, the electric telescopic rod is fixedly connected to the fixed plate, and the contact surfaces of the push block and the moving plate are both inclined surfaces.

[0012] Preferably, the scraping assembly includes a rotating shaft disposed at the top of the base, a turntable fixed at the bottom of the rotating shaft, a pull plate symmetrically rotatably connected to the top of the turntable, a movable frame rotatably connected to one side of the pull plate, a second oil tank fixed at the bottom of the movable frame, a second sliding rod slidably connected to the second oil tank, and the bottom end of the second sliding rod being fixedly connected to the scraper.

[0013] Preferably, a motor is fixed to one end of the rotating shaft, the turntable is rotatably connected to the base, and the moving frame is slidably connected to the base.

[0014] Preferably, the first oil tank and the second oil tank are filled with oil, and the first oil tank and the second oil tank are connected by a hose, and the base has a cavity that slides with the movable frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention uses a compression spring vertically installed between the connection surface of the fixed base and the screed to directly bear the vertical alternating load generated by the vibration of the screed. It is the first attenuation barrier of vibration energy, preferentially absorbing most of the high-frequency vibration reaction force. When the screed produces horizontal swaying or residual vertical vibration, the push plate deflects synchronously with the screed, converting the multi-directional vibration displacement into the axial displacement of the sliding ring. The buffer spring completes the second stage of energy absorption. The two-stage buffer structure can attenuate most of the vibration excitation force, avoiding the direct transmission of the excitation force to the main frame and causing the whole machine to resonate, thus avoiding the problems of uneven paving thickness and periodic wavy surface.

[0017] 2. This invention uses a motor to drive a turntable to swing back and forth, and a pull plate to drive a moving frame and scraper to make continuous lateral reciprocating motion along the entire paving width. This continuously smooths out the undulations and protrusions on the top surface of the material pile, maintaining a consistent material height across the entire width. After continuous smoothing by the scraper, the top surface of the material pile has a consistent height across the entire width. The lifting force of the mixture on the bottom surface of the screed is evenly distributed along the width direction, preventing the screed from being lifted by excessively high local material piles or sinking due to excessively low local material levels. This ensures the stability of the screed's floating posture from the material end, and the lateral thickness deviation of the paving layer can be controlled within a very small range, greatly improving the uniformity of thin-layer paving thickness. It also prevents the mixture from overflowing from above the side baffles, reducing material waste and on-site cleanup workload. It is especially suitable for repair work in narrow areas of urban roads, reducing the pollution of the surrounding environment during construction.

[0018] 3. This invention adjusts the initial position of the moving ring and the compression of the buffer spring according to the change in paving width, so as to achieve dynamic matching between the buffer stiffness and the working length of the screed and the magnitude of the excitation force. In the case of wide width, the stiffness is increased to avoid buffer failure due to excessive limits and to ensure vibration isolation capability. In the case of narrow width, the stiffness is reduced to avoid excessive constraint on the screed and to retain its adaptive ability for floating leveling. It can take into account both vibration isolation effect and leveling performance within the full width adjustment range. At the same time, the height of the scraper is adjusted to ensure consistent leveling effect and material stability under different paving widths, avoiding the problem of material overflow due to excessive material level in wide widths and material shortage due to excessive material level in narrow widths, and continuously ensuring the uniformity of the mixture.

[0029] Please see Figures 1 to 9 This invention provides a technical solution: a paving device for road traffic pavement maintenance, comprising a main body 1, a feeding bin 2 fixed on one side of the main body 1, a fixing plate 4 fixed on the other side of the main body 1, a telescopic plate 3 symmetrically slidably connected between the main body 1 and the fixing plate 4, a fixing seat 5 symmetrically fixed on one side of the fixing plate 4, a shock-absorbing component at the bottom of the fixing seat 5, a screed plate 7 fixed at the bottom of the shock-absorbing component, and the shock-absorbing component buffers the vibration of the screed plate 7, symmetrically arranged moving rings 8 at the top of the screed plate 7, an adjustment component between the two moving rings 8, and the position of the moving rings 8 can be adjusted by the adjustment component, a base 10 fixed between the main body 1 and the fixing plate 4, a leveling component at the top of the base 10, a scraper 12 at the bottom of the leveling component, and the leveling component drives the scraper 12 to move and level the top of the asphalt mixture pile.

[0030] In practice, the telescopic plate 3 is laterally slidable to adapt to different paving widths. The compression spring 601 and buffer spring 604, together with the push plate 602 and sliding ring 603, form a two-stage shock absorption structure, which effectively blocks the vibration of the screed 7 and prevents the frame from resonating. The position of the moving ring 8 is adjusted by the inclined transmission of the push rod 901, which dynamically adapts to the width change and adjusts the buffer stiffness. The height of the scraper 12 is adjusted synchronously through hydraulic linkage. At the same time, the crank-slider mechanism drives the scraper 12 to reciprocate and flatten the material pile, ultimately achieving stable shock absorption, uniform material distribution and high-precision paving under variable width paving.

[0031] As a further embodiment of the present invention, the shock absorption component includes a compression spring 601 disposed between the fixed base 5 and the ironing plate 7, a push plate 602 rotatably connected to the top protrusion of the ironing plate 7, a sliding ring 603 rotatably connected to one side of the push plate 602, a limit rod 605 slidably connected to the sliding ring 603, a buffer spring 604 fixed to one side of the sliding ring 603, and one end of the buffer spring 604 fixedly connected to the moving ring 8.

[0032] In practice, the high-frequency vertical alternating vibration load generated by the screed 7 can be preferentially absorbed by the compression spring 601 arranged between the fixed seat 5 and the screed 7, completing the first stage of vibration attenuation. When the screed 7 generates horizontal swaying and residual vertical vibration, it will drive the push plate 602 connected to the top to deflect synchronously, thereby driving the sliding ring 603 to slide precisely along the outer wall of the limiting rod 605, compressing the buffer spring 604 fixed between the sliding ring 603 and the moving ring 8, realizing the second stage of multi-directional vibration energy absorption. Through the linkage of the two-stage spring buffering, the excitation force generated by the operation of the screed 7 can be greatly attenuated, preventing the vibration from being directly transmitted to the frame and causing the whole machine to resonate, effectively avoiding quality defects such as uneven paving thickness and periodic wavy patterns on the road surface. At the same time, the limiting rod 605 can constrain the sliding trajectory, prevent the screed 7 from lateral swaying, and ensure the stability of the paving operation and the flatness of the paved surface.

[0033] As a further embodiment of the present invention, the limiting rod 605 is fixedly connected to the protrusion at the bottom end of the fixed seat 5, the limiting rod 605 is slidably connected to the sliding ring 603 and the moving ring 8, and the buffer spring 604 is sleeved on the outside of the limiting rod 605.

[0034] In practice, the limiting rod 605 is fixedly connected to the protrusion at the bottom of the fixed base 5 and forms a sliding fit with the sliding ring 603 and the moving ring 8. The buffer spring 604 is sleeved on the outside of the limiting rod 605. The vibration of the screed 7 drives the push plate 602 to make the sliding ring 603 slide along the axial direction of the limiting rod 605, compressing the buffer spring 604 to achieve secondary energy absorption and buffering. The limiting rod 605 plays a guiding and limiting role, ensuring that the sliding ring 603 moves smoothly along the predetermined trajectory, constraining the direction of buffering movement, preventing the screed 7 from producing abnormal lateral sway, and cooperating with the first-level compression spring 601 to achieve two-stage flexible vibration reduction, reducing the transmission of vibration to the main frame and ensuring the flatness of the paving.

[0035] As a further embodiment of the present invention, the adjustment component includes a push rod 901 disposed on one side of the fixed plate 4, a push block 904 fixed on one side of the push rod 901, and movable plates 905 slidably connected to both sides of the push block 904. One side of the movable plate 905 is fixedly connected to the movable ring 8, and a first sliding rod 902 is fixed on one side of the push rod 901. The first sliding rod 902 is slidably connected to a first oil tank 903.

[0036] In practice, push rod 901 can drive push block 904 to move. Push block 904 drives the two moving plates 905 to move laterally through inclined sliding cooperation, thereby driving the moving ring 8 fixedly connected to it to slide along the limiting rod 605, thereby adjusting the initial compression of buffer spring 604 to adapt to the excitation force under different paving widths and realize adaptive adjustment of buffer stiffness. At the same time, push rod 901 drives the first sliding rod 902 to slide within the first oil tank 903, changing the internal oil volume. Through the hydraulic linkage structure, the height of scraper 12 is synchronously adjusted to realize the linkage adaptation between stiffness adjustment and material leveling height adjustment, ensuring stable paving quality under variable width conditions.

[0037] As a further embodiment of the present invention, the first oil tank 903 is fixedly connected to a protruding position on one side of the fixing plate 4, and the push rod 901 is slidably connected to the protruding position.

[0038] In specific implementation, the first oil tank 903 is fixedly connected to the protruding position of the fixed plate 4. The push rod 901 slides along the protruding position. When the push rod 901 slides, it drives the first sliding rod 902 to slide synchronously within the first oil tank 903, changing the volume and pressure of the oil inside the first oil tank 903. The height of the scraper 12 is adjusted through the hydraulic pipeline, realizing the synchronous linkage between the paving width adjustment and the scraping height adjustment. This ensures that the material level height in the spiral distribution zone is maintained at the optimal state under different paving widths, reducing the problem of mixture segregation.

[0039] As a further embodiment of the present invention, an electric telescopic rod is fixed to one side of the push rod 901, the electric telescopic rod is fixedly connected to the fixed plate 4, and the contact surfaces of the push block 904 and the moving plate 905 are both inclined surfaces.

[0040] In practice, the electric telescopic pole provides driving force to move the push rod 901, which in turn moves the push block 904. The push block 904 and the moving plate 905 form an inclined transmission structure through the inclined contact surface, which converts the axial displacement of the push rod 901 into the lateral displacement of the moving plate 905. This adjusts the position of the moving ring 8 to change the pre-compression of the buffer spring 604, adapting to different paving widths and vibration conditions. At the same time, the hydraulic system is linked to adjust the height of the scraper 12 synchronously, realizing adaptive adjustment of the widening operation parameters.

[0041] As a further embodiment of the present invention, the scraping assembly includes a rotating shaft 111 disposed at the top of the base 10, a turntable 112 fixed at the bottom of the rotating shaft 111, a pull plate 113 symmetrically rotatably connected to the top of the turntable 112, a movable frame 114 rotatably connected to one side of the pull plate 113, a second oil tank 115 fixed at the bottom of the movable frame 114, a second sliding rod 116 slidably connected to the second oil tank 115, and the bottom of the second sliding rod 116 fixedly connected to the scraper 12.

[0042] In practice, the motor drives the rotating shaft 111 to rotate, which in turn drives the turntable 112 at the bottom to rotate synchronously. The turntable 112 drives the moving frame 114 to slide back and forth in a limited manner through the hinged pull plate 113. The moving frame 114 drives the second oil tank 115, the second sliding rod 116 and the scraper 12 fixed at the bottom to move laterally back and forth synchronously, continuously scraping the top surface of the asphalt mixture in the spiral distribution area in front of the screed 7 to maintain a uniform material level throughout the width, stabilize the force posture of the screed 7, reduce the segregation of the mixture, and improve the flatness and compaction uniformity of the thin layer paving.

[0043] As a further embodiment of the present invention, a motor is fixed at one end of the rotating shaft 111, the turntable 112 is rotatably connected to the base 10, and the moving frame 114 is slidably connected to the base 10.

[0044] In practice, the motor drives the rotating shaft 111 to rotate in both directions, causing the turntable 112 to rotate on the base 10 in a limited manner. Then, through the transmission of the pull plate 113, the moving frame 114 slides back and forth along the base 10 in a limited manner, thereby driving the scraper 12 to move laterally back and forth to flatten the top surface of the material pile, so as to achieve uniform material position across the entire width, reduce segregation of the mixture, ensure the stability of the screed 7 paving posture, and improve the paving flatness and overall quality.

[0045] As a further embodiment of the present invention, the first oil tank 903 and the second oil tank 115 are provided with oil, and the first oil tank 903 and the second oil tank 115 are connected by a hose, and the base 10 has a cavity that slides with the movable frame 114.

[0046] In practice, the first oil tank 903 and the second oil tank 115 are filled with oil and connected to each other through hoses. When the push rod 901 moves, it drives the first sliding rod 902 to change the volume of the first oil tank 903, so that the oil flows between the two oil tanks. This drives the second sliding rod 116 in the second oil tank 115 to drive the scraper 12 to adjust its height synchronously. The base 10 has a cavity, which limits and guides the moving frame 114, ensuring that the moving frame 114 slides smoothly back and forth along the predetermined trajectory. This, in turn, ensures that the scraper 12 can stably scrape the material pile horizontally back and forth, maintain a uniform material level across the entire width, reduce segregation of the mixture, and improve the paving quality.

[0047] Working principle: When using this paving equipment based on road traffic pavement maintenance, first align the main body 1 with the starting edge line of paving, and place a starting pad matching the loose paving thickness under the screed 7 to make the screed 7 fall smoothly and set the leveling sensor reference to zero. Then, turn on the scraper 12 conveyor and the screw distributor in sequence to stably transport the material to the feeding bin 2. During the operation, the main body 1 maintains a constant paving speed and the walking fine adjustment mechanism automatically corrects speed fluctuations to avoid fluctuations in paving thickness.

[0048] During the constant speed movement of the main body 1, the vertical vibration and horizontal swaying generated by the vibration operation of the ironing plate 7 cause the compression spring 601 between the fixed seat 5 and the ironing plate 7 to be compressed, completing the first stage of vertical vibration absorption. At the same time, the ironing plate 7 drives the push plate 602 connected to its top to deflect synchronously, thereby pushing the sliding ring 603 to slide axially along the outer wall of the limiting rod 605, so that the buffer spring 604 between the sliding ring 603 and the moving ring 8 is compressed. Through the two-stage synergistic action of the compression spring 601 and the buffer spring 604, the multi-directional vibration of the ironing plate 7 is flexibly buffered. The compression spring 601, as the first stage of buffer, can directly absorb the vertical alternating reaction force generated by the vibration of the ironing plate 7, greatly weakening the transmission path of the excitation force to the main frame of the main body 1, and avoiding the whole machine resonance of the frame. The second stage of buffer, formed by the buffer spring 604, can further absorb the horizontal swaying force and the remaining vertical vibration of the ironing plate 7. With the guidance and constraint of the limiting rod 605, the directional stability of the buffering process is ensured, and the lateral swaying of the ironing plate 7 is avoided.

[0049] At the same time, the motor is started, and the rotating shaft 111 rotates in both directions, which in turn drives the turntable 112, which is fixedly connected to the rotating shaft 111, to rotate in both directions at the top of the base 10. The rotating turntable 112 drives the pull plate 113, which is rotatably connected to it, to rotate in both directions, which in turn causes the moving frame 114, which is rotatably connected to the pull plate 113, to slide back and forth within the cavity opened in the base 10. Since the moving frame 114 is fixedly connected to the scraper 12 through the second oil tank 115 and the second sliding rod 116, the moving frame 114 drives the scraper 12 connected to its bottom end to move back and forth synchronously through the back and forth sliding of the moving frame 114, which scrapes the top of the asphalt mixture pile in front of the screed 7 and between the spiral distribution areas. The continuous back and forth scraping of the scraper 12 can keep the top surface of the pile in the spiral distribution area flat, and the material level height is uniform throughout the width. This makes the lifting force of the mixture on the screed 7 in the width direction balanced, ensuring the stability of the floating posture of the screed 7 and avoiding the lateral deviation of the paving thickness caused by the difference in local lifting force.

[0050] When the required road width changes, the telescopic plate 3, located between the main body 1 and the fixed plate 4, moves to adapt to the change in road width. This activates the electric telescopic rod, which in turn moves the push rod 901. The push rod 901 then synchronously moves the push block 904, which is fixed to it. Since the push block 904 and the moving plate 905 are slidably connected, and both their contact surfaces are inclined, the forward and backward movement of the push block 904 causes the moving plate 905 to move left and right. This, in turn, causes the moving ring 8, fixed to the moving plate 905, to move at the limit rod. The outer wall of 605 slides, enabling adaptive adjustment of the initial compression of the buffer spring 604. When the paving width is widened, the working length of the screed 7 increases, and the overall vibration excitation force increases synchronously. By increasing the initial compression of the buffer spring 604, the overall stiffness of the buffer system can be improved, ensuring sufficient buffering capacity under wide working conditions and avoiding excessive excitation force leading to buffer failure. When the paving width is narrowed, the preload of the buffer spring 604 decreases synchronously, which can prevent excessively high buffer stiffness from affecting the floating leveling characteristics of the screed 7 and ensure the adaptability of the screed 7 to the undulations of the base layer.

[0051] When push rod 901 moves, it drives the first sliding rod 902 fixed on one side to slide within the first oil tank 903, so that the oil in the first oil tank 903 is transported to the second oil tank 115 through the hose. This causes the second sliding rod 116, which is slidably connected within the second oil tank 115, to move outward, thereby driving the scraper 12 fixed to the second sliding rod 116 to move downward. When the paving width is widened, the scraper 12 moves downward accordingly, which can ensure that the relative height between the bottom surface of the scraper 12 and the spiral distributor is constant, ensuring that the leveling effect and the stability of the material are consistent under different widths. When the paving width is narrowed, the scraper 12 moves upward accordingly, avoiding excessive scraping that leads to insufficient material in the corner areas and preventing material spillage and segregation caused by exposed spiral blades.
