Problems solved by technology

The first type of visible light heating is easy to implement, but the heating depth is small and is not easily absorbed by the asphalt pavement, so the heating time is long
The second type of infrared radiation heating has been used in practice, but this technology still cannot solve the problem of uneven heating, which tends to age the asphalt, and has not yet developed a selective coating material that matches the asphalt pavement, so the heating efficiency is not good. High, and poor vehicle performance and other issues
[0005] Microwave energy has been relatively maturely applied in industry, and has achieved remarkable results in food, grain, tobacco, medicine and other industries, but it is still a new attempt in asphalt pavement heating. Although some enterprises and companies have developed asphalt The microwave heating plate on the road surface, but the heating efficiency is low, preventing microwave leakage, and the protection of construction personnel is not perfect; and it cannot be stirred and flattened in time after heating; the construction effect is not very ideal

Embodiment 1

[0037] Embodiment 1: Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 7, a microwave asphalt heating device is shown in the figure. A plurality of microwave generators 6 below the frame body 4, the frame body 4 is equipped with traveling wheels 2, and the stainless steel shielding layer 3 with a certain thickness opening downwards is wrapped outside the frame body 4; The lower edge of the stainless steel shielding layer 3 close to the ground is provided with an anti-leakage enclosure 7 made of flexible material; the microwave generator 6 is installed under the frame body 4 through the rubber damping block 5, and the traveling wheel 2 and the frame body 4 are connected and installed through a hydraulic shock absorber 1; the hydraulic shock absorber 1 contains an elastic piston and a cylinder 1-1, and the cylinder 1-1 is connected with the frame body 4, The lower part of the elastic piston is connected with the walking wheel; the elastic piston contains a spring 1-4 ...

Embodiment 2

[0038] Embodiment 2: The drawings are not drawn, and Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the flexible material for making the leak-proof enclosure 7 described in Embodiment 2 is aluminum foil Paper.

Embodiment 3

[0039] Embodiment 3: Refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 6, and Fig. 7. Embodiment 3 is basically the same as Embodiment 1. The same symbols in the figure represent the same meaning, and the similarities will not be repeated. , the difference is that the microwave generator in the third embodiment includes a housing, a transformer, a rectifier, a magnetron microwave stirrer, and a waveguide, and the above-mentioned transformer, rectifier, and magnetron are all located on the top of the housing.

The microwave asphalt pavement heating repairing machine includes traction power vehicle, microwave asphalt heating device connecting fore-and-aft and rotary tillaging flattening device, said asphalt heating device includes frame body and many microwave generators installed and fixed under the frame body according certain rules, the frame body is installed moving wheel, a non-corrodible steel shielding layer with certain thickness and downward mouth is covered on the said frame body; the lower edge near the ground surface of said non-corrodible steel shielding layer; said microwave generators are installed under the frame body through rubber buffer blocks, hydraulic absorber is installed between said moving wheel and frame body; the construction safety performance of the invention is improved greatly, it saves pavement repairing materials, the damping effect is good, and it is not easy to be shocked and damaged, the construction efficiency is improved; it is worth being applied in road construction department.

Description

1. Technical field [0001] The invention relates to a road repairing equipment for regenerating and repairing asphalt pavement, in particular to a microwave asphalt pavement heating device and a repairing machine thereof. 2. Background technology [0002] Asphalt roads (that is, asphalt roads) are almost all over urban and rural areas. However, due to the influence of the main material (asphalt) properties (hot soft, cold brittle), the asphalt pavement will be damaged to varying degrees after two or three years of use. There are two main reasons for this: first, the temperature in summer is high, and the road surface becomes soft, which is easy to be crushed and deformed by heavy-duty vehicles, and becomes uneven; second, when the temperature is low in winter, the road surface layer becomes brittle and easily crushed. Various cracks appear. Along with coming out of various large-scale vehicles and the situation that transport vehicle is seriously overloaded repeatedly prohi...
