Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and particularly to a paving machine for the construction of airport pavement asphalt oil and geotextile covering. Background Art

[0002] The asphalt pavement of an airport road refers to various types of airport pavements paved by mixing road asphalt materials into mineral materials. The asphalt binder improves the ability of the granular materials used for paving to resist the damage of vehicle driving or aircraft taxiing and natural factors to the road surface, making the road surface flat, less dusty, impermeable, and durable. Therefore, the asphalt pavement is a widely used high-grade pavement in airport road construction.

[0003] The asphalt pavement structure layer can be composed of a surface layer, a base layer, a sub-base layer, and a cushion layer. The asphalt-based structure layer of the asphalt pavement itself belongs to the category of flexible pavements. However, in addition to flexible materials, the base layer can also use rigid cement concrete or semi-rigid hydraulic materials. In order to improve the bonding ability between the base layer and the surface layer, a layer of asphalt oil is usually paved on the base layer. In order to prevent the surface layer from cracking, a geotextile is usually required to be laid on the asphalt oil. However, few existing mechanical devices combine the paving of asphalt oil and the laying of geotextiles, resulting in low construction efficiency. The existing patent document CN115717353A, a pavement construction method, drives a winding roller to rotate through a motor, thereby realizing the paving of the geotextile on the winding roller on the road surface, and driving a cleaning brush to rotate to clean the gravel impurities on the road surface. In addition to not having the function of simultaneously paving asphalt oil, such patent documents also have the following defects:

[0004] 1. It is very difficult for the rotation speed of the motor to match the driving speed of the vehicle, resulting in a mismatch between the output geotextile and the required amount to be laid on the road surface. Either the geotextile will accumulate on the road surface or the supply of the geotextile is likely to be insufficient.

[0005] 2. Although the rotating cleaning brush can clean the gravel impurities, the gravel impurities are easily swept to the opposite side of the road surface or still exist within the range of laying the geotextile. The former causes trouble in the laying construction of the opposite side of the road surface, and the latter causes the geotextile to be unable to closely adhere to the base layer due to the existence of the gravel impurities, resulting in a decline in construction quality. Summary of the Invention

[0006] The present invention provides a paving machine for the construction of airport pavement asphalt oil and geotextile covering, aiming to solve the problems in the background art that "few existing devices can simultaneously construct the paving of asphalt oil and geotextiles, the output of geotextiles does not match the required amount, and the cleaning effect of gravel impurities is not good".

Between the asphalt oil spreading mechanism and the traveling wheels 10, the bottom plate is connected with a cleaning mechanism.

[0030] In a further embodiment, as Figure 1 、 2 shown, at the front end of the bottom plate 1, there is a towing connector 2 for connecting with a towing device 3, and at the rear end of the bottom plate 1, there is a ladder 11.

[0031] In a further embodiment, as Figure 1 、 2 shown, there are 2 traveling wheels 10, which are respectively arranged on both sides of the front end of the bottom plate 1. There is 1 flattening roller 9, and both ends of the flattening roller 9 are rotatably connected with the bottom plate 1 through a first bracket (not marked in the figure).

As the device moves forward, the pressure roller rotates and pulls the geotextile outwards. The output speed of the geotextile matches the rotation speed of the pressure roller, and there will be no phenomenon of geotextile stacking or insufficient supply. In order to obtain a better output effect, the roller shaft of the geotextile winding roller is preferably a damping shaft. The output geotextile is pressed flat on the base layer by the flattening roller.

[0034] In a further embodiment, as Figure 1 , 2 , FIGS. 4 and 5 show that the asphalt oil spreading mechanism includes an oil tank 4 penetrating through and fixedly connected to the bottom plate 1.

[0035] In a further embodiment, as Figure 1 , 2 , FIGS. 4 and 5 show that the transition bin 6 is a cubic structure. A cylindrical shell is arranged in the transition bin 6 (as Figure 5As shown (not marked in the figure), the top of the housing is connected to the bottom end of the aggregate bin 5 through the feed inlet, and the bottom end of the housing is connected to the discharge chute 8 through the discharge outlet. A transfer roller 28 is rotatably connected inside the housing. A number of quantitative oil grooves 29 arranged axially are evenly distributed on the circumferential surface of the transfer roller 28. Both ends of the roller shaft of the transfer roller 28 are rotatably connected to the left and right ends of the transition bin 6. A stepping motor 7 is provided on the outer surface of one end of the transition bin 6. The output shaft of the stepping motor 7 is fixedly connected to one end of the roller shaft of the transfer roller 28. The stepping motor 7 is electrically connected to the storage battery through a wire. The control panel is provided with a stepping motor control button. In this embodiment, when paving asphalt oil, the stepping motor is started to rotate at a constant speed, the traction device moves at a constant speed, and the asphalt oil is quantitatively output to the road surface through the quantitative oil grooves 29 to ensure uniform paving of the asphalt oil.

[0036] In a further embodiment, as Figure 1 、 2 、6 shows, the cleaning mechanism includes a mounting plate 20. The mounting plate 20 is provided with multiple rows of uniformly inclined connection holes 30. A cleaning brush 21 is connected to each row of connection holes 30.

The driving motor 22 is electrically connected to the storage battery. The control panel is provided with a driving motor control button. In this embodiment, each cleaning brush is inclined. When in use, as Figure 6 shown, the crushed stone particles are swept to the roadside instead of the opposite side of the road surface. Multiple cleaning brushes have a unified slope and can cooperate with each other to achieve high-quality cleaning of the crushed stone impurities on the road surface. When it is necessary to adjust the width of the cleaning mechanism, the fixing plate can be connected to a new connection hole position to make the width of the cleaning mechanism match the road surface.

[0037] In a further embodiment, as Figure 1 、 2 shown, a camera 13 is fixedly connected to the rear end of the upper surface of the bottom plate 1 through a third bracket. The camera 13 is used to photograph the road surface where the geotextile and asphalt oil have been laid. The camera 13 is connected to a display mechanism (not shown in the figure) through a wire.
