Description

Technical Field

[0001] This invention relates to the field of water-stabilized double-layer continuous paving construction technology, specifically to a construction device and method for water-stabilized double-layer continuous paving structural layer. Background Technology

[0002] Currently, the most common construction method for semi-rigid subbase and base courses of cement-stabilized crushed stone is layered construction. This means that after completing the first layer of cement-stabilized crushed stone, it is typically cured for 7 days and only after passing inspection is the next layer constructed. Double-layer (or multi-layer) continuous paving refers to immediately constructing the next layer of cement-stabilized crushed stone after the first layer is formed, continuing until the top layer of cement-stabilized crushed stone is completed within a specified time. In existing double-layer continuous paving processes, after the first layer of cement-stabilized crushed stone has reached a certain length, the work immediately returns to construct the second layer.

[0003] However, in the current construction process of water-stabilized layer paving, stones tend to accumulate, which leads to unevenness during the paving process. This affects the subsequent road construction. Furthermore, when stones are piled up, they need to be manually spread out, resulting in high labor intensity for workers. Summary of the Invention

[0012] Preferably, both ends of one side of the mounting plate are equipped with electric push rods by screws, and the ends of the two electric push rods are connected by a pressing roller.

[0013] Preferably, an adjustable electric telescopic rod is installed at both ends of one side of the mounting plate near the position of the pressing electric push rod by screws. A fixing plate is installed at one end of the adjustable electric telescopic rod by screws. Spring dampers are installed at both ends of the fixing plate by screws. A mounting block is installed between the two spring dampers by screws. Guide plates are installed at the bottom of the two mounting blocks by screws. A bevel gear connecting mechanism is fixedly installed at one end of one roller. A drive rod is meshed at one end of the bevel gear connecting mechanism. A cam is installed at one end of the drive rod by screws.

[0014] Preferably, the cam is in contact with the outer side of the guide plate, the guide plate has a V-shaped cross-section, and the driving rod is movably mounted on one end of the mounting plate.

[0021] During the stone paving process, the angles of the limiting plates and baffles can be adjusted according to different road widths to guide the stones. This allows the construction device to adapt to different road widths, expanding its applicability. As the device moves, it drives the rotation of the fixed and adjustable mixing blades, mixing the stones at the top of the conveyor belt to prevent large stones from accumulating and affecting subsequent flattening. Furthermore, the device's movement drives the moving plate and pushing plate to reciprocate, moving the stones at the top of the conveyor belt and ensuring their flatness. This facilitates even paving of the stones on the road surface, improving the overall paving efficiency. The system improves efficiency and effectiveness. After the stones are laid, the pressing roller presses down on top of them to ensure compactness, facilitating the subsequent application of asphalt and ensuring road surface usability. It also guides stones falling from the top of the conveyor belt, ensuring the flatness of the stone paving. When the device moves, the bevel gear connection mechanism drives the drive rod to rotate, which in turn drives the cam to rotate. This causes the cam to continuously contact the guide plate, making the guide plate vibrate. This prevents stones from sticking to the guide plate and wasting them, and it also vibrates the stones at the end of the guide plate, further ensuring a more uniform and even stone paving.

[0034] Both the slider 10 and the chute 11 have T-shaped longitudinal sections. The gear ratio of the driving gear 13 and the drive gear 14 is 4:1. The limiting plate 7 has a corresponding hole at the position of the stirring rod 15.

[0035] A roller 5 is fixedly connected to a second belt connecting mechanism 19 at one end, and a reciprocating threaded rod 20 is fixedly connected to a reciprocating threaded rod 20 at one end. A movable plate 31 is threadedly connected to the outside of the reciprocating threaded rod 20. A limit post 33 is slidably connected inside the movable plate 31.

[0037] The construction method of the water-stabilized double-layer continuous paving structural layer construction device includes:

[0038] S1: Open the limit electric telescopic rod 6 according to the width of the road surface, and adjust the position of the limit plate 7 and the baffle 8;

[0039] S2: Then activate the electric push rod 21 and the bevel gear connecting mechanism 28 to adjust the position of the pressing roller 22 and the guide plate 27;

[0040] S3: Place the stone on conveyor belt 2 and turn on conveyor belt 2 to realize stone transportation;

[0041] S4: Then start the drive motor 3, drive the device to move, and then complete the laying of the stone.

[0042] Personnel start the drive motor 3, which, through the drive connection mechanism 4, drives the roller 5 to rotate, thus moving the construction device. Then, personnel place stones on top of the conveyor belt 2. Depending on the road surface to be paved, the limit electric telescopic rod 6 is activated, moving the limit plate 7. After the limit plate 7 is moved to the appropriate position, its movement causes the baffle 8 to rotate, allowing the slider 10 to move inside the chute 11. The baffle 8 is then adjusted to a suitable angle, and the conveyor belt 2 is started to transport the stones. Guided by the baffle 8 and the limit plate 7, the stones are guided, allowing the construction device to adapt to different road widths and expanding its applicability. During the movement of the construction device, the rotation of the roller 5 drives the first belt connection mechanism 12 to rotate, thereby driving the... The rotation of gear 13 drives the rotation of drive gear 14, which in turn drives the rotation of stirring rod 15, which in turn drives the rotation of fixed stirring blade 16 and adjusting stirring blade 18. This stirs the stones at the top of conveyor belt 2, preventing large stones from accumulating and affecting subsequent stone flattening. During the movement of the device, the rotation of second belt connecting mechanism 19 drives reciprocating threaded rod 20, which in turn drives moving plate 31 and pushing plate 32 to move back and forth, pushing the stones at the top of conveyor belt 2 to ensure the flatness of the stones at the top of conveyor belt 2. This allows the stones to be evenly spread on the road surface, improving the efficiency and effectiveness of stone paving.

[0043] Personnel activate the electric push rod 21, which moves the pressing roller 22 to a suitable height. During the movement of the device, the pressing roller 22 presses down on the top of the stone, ensuring a compact shape after laying. This facilitates the subsequent application of asphalt on top of the stone, ensuring the road surface's usability. Activating the electric telescopic rod 23 moves the fixed plate 24, which in turn moves the guide plate 27. This further guides the stones falling from the top of the conveyor belt 2, ensuring the flatness of the stone laying. During the device's movement, the bevel gear connecting mechanism 28 drives the drive rod 29 to rotate, which in turn drives the cam 30 to rotate. The cam 30 continuously contacts the guide plate 27, causing it to vibrate. This prevents stones from sticking to the guide plate 27, avoiding waste, and also vibrates the stones at the end of the guide plate 27, further ensuring a more even laying of the stone.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
