[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the internal connection of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0029] Attached Figure 1 The figure shows the overall structure of the airport pavement paving equipment. Figure 1 It can be seen that the airport pavement paving equipment is mainly composed of a flatbed truck 1, a concrete spreading device 2, a concrete vibrating device 3, and a vibrating ruler 4. Its structure and function are described in detail below.

[0030] See attached Figure 2 , attached Figure 2 The three-dimensional structure diagram of the flatbed vehicle 1 is shown. Figure 2 It can be seen that the flatbed truck 1 has four height-adjustable wheels 13. In the present embodiment, hollow columns 11 are provided at the four corners of the flatbed truck 1, and two upper and lower pin holes are provided on the hollow column 11. The wheel 13 is mounted on the lower end of a slide column 12, and a pin hole is provided on the slide column 12. The slide column 12 can slide up and down in the hollow column 11, and the pin hole on the slide column 12 can be coaxially connected with any pin hole on the hollow column 11 through a pin shaft 14. When the pin hole on the slide column 12 is coaxially connected with the lower pin hole on the hollow column 11, the distance between the wheel 13 and the vehicle body increases; when the pin hole on the slide column 12 is coaxially connected with the upper pin hole on the hollow column 11, the distance between the wheel 13 and the vehicle body decreases.

[0031] It is noteworthy that the wheel 13 can also be height-adjustable by a hydraulic lifting column, which is not described here. In addition, the wheel 13 also has a motor, which can drive the flatbed vehicle 1 to walk independently.

[0032] See attached Figure 3 , attached Figure 3 FIG. 2 shows a cross-sectional structural diagram of a concrete paving device 2. Figure 3 It can be seen that the concrete paving device 2 includes a concrete hopper 21 fixed on the flatbed truck 1, a rotating shaft 22 is provided at the discharge port of the concrete hopper 21, and a pair of material troughs 221 corresponding to the discharge port are provided on the rotating shaft 22.

[0033] The rotating shaft 22 is driven to rotate by a motor. When the trough 221 faces the discharge port, the concrete in the concrete hopper 21 falls into the trough 221. As the rotating shaft 22 rotates, the discharge port is blocked by the cylindrical surface of the rotating shaft 22, and the concrete in the trough 221 falls into the scraper 15. In this way, as the rotating shaft 22 continues to rotate, not only can the quantitative dropping of concrete be achieved, but the dropped concrete is in a paving state with uniform thickness without manual intervention.

[0034] A vibrator 23 is installed on the side wall of the concrete hopper 21. The vibrator 23 can make the concrete in the concrete hopper 21 in a uniform state through vibration, so as to ensure that the concrete can always evenly fill the material trough 221, which is beneficial to improving the uniformity and flatness of concrete paving.

[0035] The scraper 15 is arranged at the bottom of the flatbed vehicle 1, and the scraper 15 is funnel-shaped and is located below the rotating shaft 22. The scraper 15 has two functions, one is to guide and concentrate the concrete falling from the rotating shaft 22, and the other is to scrape the concrete piled too high on the ground.

[0036] After paving, the concrete should be vibrated. Figure 4 , attached Figure 4 FIG. 2 shows a three-dimensional structural diagram of a concrete vibrating device 3. Figure 4 It can be seen that the concrete vibrating device 3 includes eight transversely arranged vibrating rods 31, which are hinged at the rear of the flatbed truck 1 and can rotate around the hinge axis under the drive of the oil cylinder 32. In this embodiment, the eight vibrating rods 31 are fixed on a crossbar 33, and a pair of oil cylinders 32 are hinged between the flatbed truck 1 and the crossbar 33. In this way, a downward pressure can be applied to the eight vibrating rods 31 through the pair of oil cylinders 32, so that the working parts of the vibrating rods 31 extend into the concrete slurry to vibrate the concrete. The depth of the vibrating rods 31 extending into the concrete slurry can be adjusted by the oil cylinder 32, and when not in use, the vibrating rods 31 can be lifted upward by the oil cylinder 32.

[0037] After vibrating, the concrete pavement needs to be leveled using a vibrating ruler 4. Figure 1 A towing hook is provided at the tail of the flatbed truck 1, and a vibrating ruler 4 is towed on the towing hook of the flatbed truck 1 through a rope 5. In this way, when the flatbed truck 1 is moving forward, the vibrating ruler 4 can vibrate the concrete pavement with the upper plane of a pair of concrete casting partitions 6 as a reference.

[0038] Attached Figure 1 In the embodiment, the four wheels 13 of the flatbed vehicle 1 are all on the ground. In another embodiment, the road surface on one side of the flatbed vehicle 1 has been paved, and the other side has not been paved, and the height of the wheels 13 needs to be adjusted.

[0039] See attached Figure 5 , attached Figure 5 The structure diagram of the flatbed truck 1 when the wheel 13 on one side is raised is shown. Figure 5 It can be seen that the road surface on one side of the flatbed truck 1 has been paved, while the other side has not yet been paved. At this time, the sliding column 12 and the wheel 13 on the side where the road surface has been paved can be raised through the pin shaft 14 to ensure that the flatbed truck 1 does not tilt.

[0040] From the above, it can be seen that the airport pavement paving equipment can continuously realize the paving, vibration and leveling of airport pavement concrete, and basically no human participation is required throughout the process. It not only greatly reduces the labor input and labor intensity, but also improves the standardization of construction, so that the quality of the paved concrete pavement is guaranteed.

[0041] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the protection scope of the present invention is defined by the attached claims and their equivalents.
