V-shaped grooving machine for pavement bending crack repairing construction

Abstract

The invention provides a V-shaped grooving machine for pavement bending crack repairing construction. The machine comprises an upper machine frame and a lower machine frame, a flying dust collecting device, a grooving device, a motor, a triangular belt, a motor belt wheel, an upper twisting seat, a bearing, a grooving belt wheel, a dust collecting spring, a guide sleeve, a handrail and a nut whichare installed on the upper machine frame, and a universal wheel, a supporting land wheel, a lower twisting seat and a screw rod seat which are installed on the lower machine frame, the left ends of the upper machine frame and the lower machine frame are hinged through a hinge seat shaft through which the upper hinge seat and the lower hinge seat are communicated in series; the grooving machine ischaracterized in that the surface of a conical cutter body of the grooving machine is provided with cutting edges which are arranged on a plurality of spiral lines with the screw pitches gradually reduced from top to bottom, the overall dimensions of the cutting edges are gradually reduced, and the two hollow semi-drum-shaped flying dust collecting devices are symmetrically installed on the leftside and the right side of the grooving machine. According to the machine, a V-shaped groove can be cut at a time in the pavement crack bending direction, and cut powder settles in a dust collecting cavity in the bottom of the flying dust collecting device.

Description

technical field [0001] The invention relates to the technical field of road surface maintenance engineering machinery, and is a slotting device suitable for repairing road surface cracks. Background technique [0002] Municipal roads, especially asphalt concrete pavement or cement concrete pavement, in the process of construction and use, due to various reasons, the road surface will inevitably appear curved cracks of different lengths, widths, depths, and shapes, which not only affect the appearance of the road surface, reduce the In addition, cracks can easily absorb corrosive gases and moisture in the atmosphere, as well as rainwater, snow water or moisture sprayed on artificial roads. When the ambient temperature is lower than -5ºC, the water in the cracks freezes and expands, causing cracks The expansion of width and depth will cause the road base, subbase, and even the roadbed to be eroded by water over time, which will cause the road surface to collapse, thereby affec...

AI Technical Summary

Problems solved by technology

If the joints are filled directly without slotting or if the slotting depth is not enough or the slotting cannot be accurately along the original cracks, the caulking material cannot fill and embed the gaps. As the vehicle rubs on the road, the caulking material It is easy to fall off from the gap, thus losing the meaning of crack repair
