Description

Technical Field

[0001] The invention relates to the field of road surface repair, and in particular to an asphalt road surface repair device. Background Art

[0002] In high-grade highways, asphalt pavement is valued for its well-known good performance. As a seamless continuous pavement, it has good mechanical strength, a flat and wear-resistant surface, smooth and comfortable driving performance, no dust, low vibration, low noise, short construction period and simple maintenance and repair. It is widely used in expressways. After the highway is built and opened to traffic, the quality of the highway will gradually decrease due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, wind and sand, ice and snow, sunlight and ice melting, as well as human destruction and certain defects left over from construction.

[0003] When repairing asphalt road pavement, first use a cutting machine to neatly cut out the edges of the damaged area of ​​the road surface. The cut area is generally in the shape of a long groove. Then, use tools to manually clean the gravel in the groove. After that, apply a layer of hot asphalt (or emulsified asphalt) tack coat evenly on the four walls and bottom of the cleaned pit. The amount is generally 0.3-0.6L / m. This helps to improve the adhesion between the asphalt and the groove. Finally, pour asphalt into the groove to spread and complete the repair.

[0004] In the oiling process of repairing asphalt pavement, due to the different locations and sizes of potholes, emulsified asphalt is generally applied to the inside of the potholes by manual brushing. During this process, if the operator accidentally touches the emulsified asphalt to the skin, it will cause skin allergies, redness, swelling, itching and other discomfort symptoms. These symptoms are not only uncomfortable, but also seriously affect work efficiency and safety. Summary of the invention

[0005] The main purpose of the present invention is to provide an asphalt pavement repair device, which solves the problem of manually brushing emulsified asphalt on the inside of potholes by providing a positioning mechanism, a cutting mechanism and a feeding mechanism.

[0027] 1.

[0029] 3. In the present invention, the three side walls of the pit are determined by the mounting plates of the three groups of positioning members, and then the horizontal electric push rod is started to drive the mounting frame to detach from the slot, and then the adsorption member is placed on the top of the limit plate, and the sponge is in contact with the top surface of the limit plate, and then the adsorption member is pushed to move.
