Description

Technical Field

[0001] The present invention relates to the technical field of municipal construction, and specifically to a road surface paving and rolling device for municipal engineering. Background Art

[0002] Road surface paving and rolling devices for municipal engineering are crucial mechanical equipment in urban construction. They are specifically used for compacting the surfaces of newly built or renovated roads. These devices apply sufficient pressure to the road surface materials through their heavy rollers or additional vibration and impact systems to expel air and moisture, and to promote close contact between material particles, thereby enhancing the density, stability, and durability of the road surface. Whether it is an asphalt road surface, a cement concrete road surface, or other types of road surfaces, road surface paving and rolling devices for municipal engineering can effectively improve their load-bearing capacity and service life.

[0003] In current road rolling equipment technologies, although some road rollers are innovatively equipped with asphalt road surface cutting devices on both sides of the rolling drums, which improve construction efficiency and material recycling rates, their designs still have deficiencies. Specifically, there is inevitably a certain gap between the cutting edges of the cutting devices and the rolling drums. This gap problem highlights two major drawbacks in actual operations. Since it is not convenient to adjust the position of the cutting devices, the existence of the gap limits the accuracy of road surface cutting. During the process of the road roller rolling and synchronously cutting the asphalt road surface, due to the small distance between the cutting edges and the roller surface, the cutting edges are not smooth enough, and there may even be uncut asphalt residues. This not only affects the overall aesthetics of the road surface but may also cause unevenness in the subsequent laying layer, thereby affecting the service life of the road and driving comfort. For this reason, we propose a road surface paving and rolling device for municipal engineering. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figure 1-4 , the present invention provides a technical solution: a municipal road pavement paving and rolling device, including a road rolling mechanism 1. On both sides of the center of the lower end of the road rolling mechanism 1 near both ends, cutting units for cutting and indentation of the asphalt pavement are provided. On both sides of the center of the lower end of the road rolling mechanism 1 near both ends, adjusting mechanisms 3 for driving the cutting units to move are provided. On one side of the center of the lower end of the road rolling mechanism 1, an installation mechanism 2 for installing and supporting the two adjusting mechanisms 3 is provided. The cutting unit includes a pressing-down mechanism 4, a limiting mechanism 5, an opening and closing mechanism 6, a cutting mechanism 7, a first auxiliary mechanism 8, a second auxiliary mechanism 9, and a driving mechanism 10.

[0034] Furthermore, as the main part of the overall device, the road roller mechanism 1 is responsible for the main compaction operation on the road surface. At a position near both ends on one side of the center at the lower end of the road roller mechanism 1, cutting units for cutting and indentation of asphalt pavement are specially designed. These cutting units can play a key role under specific construction requirements, such as when lane lines need to be demarcated or the road surface is uneven. The main function of the adjustment mechanism 3 is to drive the cutting units to move horizontally. Through the precise control of the adjustment mechanism 3, the cutting units can make precise position adjustments on the road surface according to construction requirements to adapt to different cutting and indentation needs. The installation mechanism 2 is located at one side of the center at the lower end of the road roller mechanism 1. It undertakes the installation and support of the two adjustment mechanisms 3. The stability and strength of the installation mechanism 2 are directly related to the operating efficiency and safety of the entire cutting system. The cutting unit contains multiple complex and precise mechanisms that work together to complete the cutting and indentation operations. The downward pressure mechanism 4 is responsible for controlling the downward pressure depth of the cutting tool or indentation tool to ensure the accuracy and consistency of cutting or indentation. The limit mechanism 5 is used to limit the movement range of the tool to prevent over-cutting or damage to the road surface. The opening and closing mechanism 6 controls the opening and closing actions of the cutting tool or indentation tool to achieve the start and stop of cutting or indentation. The cutting mechanism 7 is the part that actually performs the cutting operation and can efficiently cut the asphalt pavement. The driving mechanism 10 cooperates with the first auxiliary mechanism 8 and the second auxiliary mechanism 9 to drive its various mechanisms to work together to complete complex cutting and indentation tasks.

[0035] In a preferred technical solution of this embodiment, please refer to Figure 1-Figure 4 As shown, the road roller mechanism 1 includes a control room 101. An engine 102 is assembled at a position near the lower part on one side of the control room 101. Driving wheels 105 are installed at the center near the lower part on both sides of the engine 102. A steering frame 103 is assembled at a position near the lower part on one side of the lower end of the control room 101. A road roller 104 is assembled inside the steering frame 103. The installation mechanism 2 includes a docking plate 201. The docking plate 201 is fixedly connected to the center near the lower part on one side of the lower end of the steering frame 103. A support block 202 is fixedly connected to the center at the lower end of the docking plate 201. A support plate 203 is fixedly connected to one side of the support block 202. The support plate 203 and the docking plate 201 are fixedly connected to each other on the side close to each other.

[0036] Furthermore, as the core, the road roller mechanism 1 integrates the control room 101, the engine 102, the driving wheels 105, the steering frame 103 and the road roller 104. Through the power provided by the engine 102, the driving wheels 105 achieve flexible movement, and the road roller 104 inside the steering frame 103 effectively compacts the road surface. The installation mechanism 2, with its stable structure of the docking plate 201, the support block 202 and the support plate 203, provides a solid installation foundation for the road roller mechanism 1, ensuring stability and reliability during the operation process.

[0037] In a preferred technical solution of this embodiment, please refer toFigure 1 , Figure 3 and Figure 8 As shown in Figure 3 and Figure 8 , each of the two adjusting mechanisms 3 includes a sliding frame 301. The two sliding frames 301 are respectively fixedly connected to the two ends near the center of the side of the support plate 203 close to the steering frame 103. At the positions near the two sides of the center inside the two sliding frames 301, support bearings 302 are fixedly sleeved. At the centers of the upper inner wall and the lower inner wall of the two sliding frames 301, guide grooves 303 are opened. At one side, the inner rings of the two support bearings 302 on one side and the two support bearings 302 on the other side fixedly sleeve two lead screws 304. On the outer sides of the two lead screws 304, sliders 305 are threadedly sleeved. The two sliders 305 are respectively slidably sleeved inside the two sliding frames 301. At the centers of the upper ends and the lower ends of the two sliders 305, guide rails 306 are fixedly connected. The four guide rails 306 are respectively slidably sleeved inside the four guide grooves 303. At the positions near the upper and lower ends of the center of one side of the two sliders 305, positioning plates 307 are fixedly connected. At one side, the inner rings of the two positioning plates 307 on one side and the two positioning plates 307 on the other side fixedly sleeve two support sleeves 308. At the mutually remote ends of the two lead screws 304, handwheels 309 are fixedly connected.

[0038] Further, with the road rolling mechanism 1 as the core, functions of control, power, movement and compaction are integrated to ensure the initial compaction of the road surface. The installation mechanism 2 thereon provides a stable foundation for the adjusting mechanism 3 through stable connecting components. The adjusting mechanism 3 uses the support bearings 302 in the sliding frame 301 to support the lead screws 304. By rotating the lead screws 304 through the handwheels 309, the sliders 305 are driven to slide along the guide rails 306 in the guide grooves 303, thereby driving the positioning plates 307 and the support sleeves 308 to adjust their positions. This precisely designed adjusting mechanism 3 enables the compaction operation of the road roller 104 to be flexibly adjusted according to specific requirements, further improving the operation efficiency and the road surface compaction quality.

[0039] In a preferred technical solution of this embodiment, please refer to Figure 5-Figure 10 As shown in Figure 5-Figure 10 , the downward pressing mechanism 4 includes a first hydraulic rod 401. The first hydraulic rod 401 is fixedly sleeved inside the support sleeve 308. The output section of the first hydraulic rod 401 is fixedly connected with a first rotating sleeve 402. At the lower positions on both sides of the first hydraulic rod 401, clamping plates 403 are fixedly connected. At the position near one side of the center inside the two clamping plates 403, a first rotating rod 404 is rotatably sleeved. On the outer side of the first rotating rod 404 near one side, a first nut 405 is threadedly sleeved. The limiting mechanism 5 includes a triangular frame 501. At two of the angles of the triangular frame 501, a second rotating sleeve 502 and a third rotating sleeve 503 are respectively fixedly connected. The second rotating sleeve 502 is rotatably sleeved on the outer side of the center of the first rotating rod 404, and the second rotating sleeve 502 is arranged between the two clamping plates 403.

[0040] Furthermore, the pressing mechanism 4 utilizes the power of the first hydraulic rod 401 to drive the first rotating sleeve 402 and its attached components to move vertically, achieving precise downward pressing control of the cutting tool head 707 to meet the cutting or marking requirements of different asphalt pavements. The clamping plate 403 and the first rotating rod 404 form a stable support structure, and the triangular frame 501 in the limiting mechanism 5 is connected to the first rotating rod 404 through the second rotating sleeve 502, effectively restricting the rotational offset during the downward pressing process and ensuring the stability of the operation and the accuracy of cutting and marking.

[0041] In a preferred technical solution of this embodiment, please refer to Figure 10-Figure 11 As shown, the opening and closing mechanism 6 includes a pressing rod 601. A support rod 602 is fixedly connected to the center of one side of the pressing rod 601. Fourth rotating sleeves 603 are fixedly connected to one end of the pressing rod 601 and one end of the support rod 602 respectively. A second rotating rod 604 is sleeved inside the two fourth rotating sleeves 603. A second nut 605 is threadedly sleeved on one end of the second rotating rod 604. The center of the outer side of the second rotating rod 604 is rotatably sleeved inside a third rotating sleeve 503, and the third rotating sleeve 503 is arranged between the two fourth rotating sleeves 603. A third rotating rod 606 is sleeved inside the support rod 602 and near one end of the center of one side of the pressing rod 601 close to the fourth rotating sleeve 603. The first rotating sleeve 402 is rotatably sleeved on the center of the outer side of the third rotating rod 606. A third nut 607 is threadedly sleeved on the outer side of the third rotating rod 606 near one end.

[0042] Further, the pressing rod 601 serves as the main body of the opening and closing mechanism 6. At the center of one side of the pressing rod 601, a supporting rod 602 is fixedly connected. The two together form the basic framework of the opening and closing mechanism 6. At one end of the pressing rod 601 and one end of the supporting rod 602, two fourth rotating sleeves 603 are respectively fixedly connected. A second rotating rod 604 is sleeved inside the two fourth rotating sleeves 603. The second rotating rod 604 and the second nuts 605 at both ends thereof mainly play the role of installation and positioning. They rotatably connect the pressing rod 601 and the supporting rod 602 together. The center of the outer side of the second rotating rod 604 is rotatably sleeved inside the third rotating sleeve 503, and the third rotating sleeve 503 is sleeved on the triangular frame 501 connected to the limiting mechanism 5. This design enables the opening and closing mechanism 6 to rotate relative to the limiting mechanism 5, providing a basis for subsequent opening and closing actions. To achieve the opening and closing actions, a third rotating rod 606 is also sleeved between the pressing rod 601 and the supporting rod 602. The first rotating sleeve 402 is rotatably sleeved at the center of the outer side of the third rotating rod 606. This means that the first rotating sleeve 402 and the pressing mechanism 4 connected thereto can rotate relative to the opening and closing mechanism 6. Similar to the second rotating rod 604, the third nut 607 on the outer side of the third rotating rod 606 also mainly plays the role of installation and positioning. It ensures the rotational connection between the third rotating rod 606 and the pressing rod 601 and the supporting rod 602. This design enables the cutting cutter head 707 to be flexibly adjusted for opening and closing according to the road surface conditions and working requirements, thereby improving the adaptability and operation efficiency of the device. At the same time, since the opening and closing mechanism 6 adopts a precise rotating sleeve and rod connection structure, the smoothness and reliability of the opening and closing actions are ensured.

[0043] In a preferred technical solution of this embodiment, please refer to Figure 11 As shown, the cutting mechanism 7 includes a support disk 701. The support disk 701 is fixedly connected to the end of the pressing rod 601 away from the fourth rotating sleeve 603. At the center of one side of the support disk 701, a support column 702 is fixedly connected. A second bearing 703 is fixedly sleeved on the outer side of the support column 702. A docking cover 704 is fixedly sleeved on the outer side of the second bearing 703. A positioning ring 705 is fixedly sleeved on the outer side of the docking cover 704 near one end of the support disk 701. A plurality of positioning bolts 706 are fixedly connected in a circular arrangement at the center near the edge on the side of the positioning ring 705 away from the support disk 701. A cutting cutter head 707 is arranged on the side of the positioning ring 705 away from the support disk 701. Positioning holes 708 are formed through the cutting cutter head 707 in a circular arrangement at the center near the edge. The plurality of positioning holes 708 are respectively sleeved on the outer sides of the plurality of positioning bolts 706, and the cutting cutter head 707 and the positioning ring 705 are detachably connected. Tightening nuts 709 are threadedly sleeved on the outer sides of the plurality of positioning bolts 706 near one end.

[0044] Furthermore, as a component directly acting on the road surface, the cutting mechanism 7 is designed with full consideration of cutting efficiency and durability. The close cooperation of components such as the support disk 701, support column 702, second bearing 703, docking cover 704, positioning ring 705, and cutting cutter head 707 ensures the smoothness and high efficiency of the cutting process. At the same time, through the detachable design of the positioning bolt 706 and fastening nut 709, it is convenient for users to replace the cutting cutter head 707 of different specifications or worn ones according to needs.

[0045] In a preferred technical solution of this embodiment, please refer to Figure 11-Figure 13 As shown, the first auxiliary mechanism 8 includes two fifth rotating sleeves 801, which are respectively limited and rotatably connected to the outer sides of the third rotating rod 606 near both sides of the center. One side of the two fifth rotating sleeves 801 is fixedly connected to the first V-shaped frame 802. At the end of the first V-shaped frame 802 far from the two fifth rotating sleeves 801, a second V-shaped frame 803 is fixedly connected. At both ends of the second V-shaped frame 803 far from the first V-shaped frame 802, sixth rotating sleeves 804 are fixedly connected. A fourth rotating rod 805 is sleeved inside the two sixth rotating sleeves 804. A fourth nut 806 is threadedly sleeved on the outer side of the fourth rotating rod 805 near one end. The second auxiliary mechanism 9 includes a connecting strip 901. At one end of the connecting strip 901 close to the fourth rotating rod 805, a seventh rotating sleeve 902 is fixedly connected. The seventh rotating sleeve 902 is rotatably sleeved on the outer side of the center of the fourth rotating rod 805. At the end of the connecting strip 901 far from the seventh rotating sleeve 902, a V-shaped plate 903 is fixedly connected. Link rods 904 are fixedly connected to both ends of the V-shaped plate 903.

[0046] Furthermore, the first auxiliary mechanism 8 and the second auxiliary mechanism 9 further enhance the flexibility and stability of the cutting unit. The design of components such as the first V-shaped frame 802, second V-shaped frame 803, sixth rotating sleeve 804, and fourth rotating rod 805 enables the cutting unit to make fine adjustments according to different road conditions during operation to adapt to complex operating environments. The connecting strip 901, V-shaped plate 903, and link rods 904, driven by the second hydraulic rod 1004, further adjust the overall posture of the cutting unit.
