Pavement notch forming device for asphalt pavement

Abstract

The invention provides a pavement notch forming device for a asphalt pavement, and the phenomena that a cutting disc is stuck and broken due to the fact that the pavement sunken part and the pavement height change ceaselessly in the grooving process are avoided; meanwhile, a depth keeping device is adopted so that the downward cutting depth from the pavement can be consistent all the time. The technical scheme is that the pavement notch forming device comprises a vehicle body, and is characterized in that the pavement notch forming device further comprises a driving assembly located at the upper end of the vehicle body and a cutting disc fixedly connected with the output end of the driving assembly, the cutting disc is pressed through the pressing rod, and the downward cutting depth of the cutting disc is controlled through the depth detection piece. According to the automatic cutting device, multiple use modes are considered, meanwhile, the automatic cutting device can be used on multiple road conditions, and the cutting depth can be kept all the time and automatically adjusted.

Description

technical field [0001] The invention relates to a device for road construction, in particular to a device for opening notches on asphalt pavement. Background technique [0002] Asphalt pavement has flat surface, no joints, comfortable driving, low vibration, low noise, wear resistance, no dust and easy cleaning, short construction period, easy maintenance and repair, recyclable utilization, and suitable for phased construction. Mainly, but the asphalt pavement will have local sags and cracks after long-term use, and once the asphalt pavement is sag, it will become larger and larger during the driving process, which will eventually lead to roadbed damage. For seams, it is necessary to cut off the recessed part as a whole during maintenance, and at the same time, the cut part needs to be flat to facilitate refilling of asphalt material. However, in the cutting process, the existing technology uses a slotting machine for slotting, because the slotting machine is in the Walking...

Problems solved by technology

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a pavement notch opening device for asphalt pavement, which not only solves the problem of cutting disc jamming, Breaking and other phenomena, at the same time, the depth maintenance device is used to make the cutting depth from the road surface consistent. At the same time, the cutting depth will be automatically adjusted after the shape of the road surface changes, so that the cutting depth is always maintained at the set depth. The technical solution is, Including the car body, it is characterized in that it also includes a drive assembly located at the upper end of the car body, a cutting disc fixedly connected to the output end of the drive assembly, the cutting disc is pressed by a pressing rod, and the downward cutting depth of the cutting disc is controlled by a depth detection member. The depth detection part includes an upper telescopic rod and a lower telescopic rod that are connected to the side of the pressing rod by rotation and sliding vertically and cooperate with each other. The lower end of the lower telescopic rod is provided with an arc-shaped piece, and the upper end of the upper telescopic rod is connected to the vehicle body through a connecting rod. , the vertical sliding connection on the upper telescopic rod is equipped with a depth maintaining device
