U-shaped grooving machine for pavement bending crack repairing construction

Abstract

The invention provides a U-shaped grooving machine for pavement bending crack repairing construction. The grooving machine comprises a dust collecting device, a grooving device, a motor, a triangularbelt, a motor belt wheel, an upper twisting seat, a grooving device belt wheel, a bearing, a depth scale, a handrail, a nut, a guide sleeve and a dust collecting spring which are installed on an uppermachine frame, and a lower twisting seat, a screw rod seat, a universal wheel and a supporting ground wheel which are installed on a lower machine frame. The left ends of the upper machine frame andthe lower machine frame are hinged through a rotating shaft through which the upper hinge seat and the lower hinge seat are communicated in series; the grooving device is positioned at the right end through a hand wheel and a screw rod according to the depth scale; the grooving machine is characterized in that a cutter body of the grooving device is formed by combining a cylinder and a cone, thesurface is provided with different cutting edges which are arranged along in a dual-head spiral line and protruded outside, the grooving device is surrounded by an inner hollow drum type dust collecting device, a U-shaped groove can be formed in the road surface crack bending direction at a time, cut crushed materials and dust settle in a dust collecting cavity of the dust collecting device, and the road surface crack cutting machine is simple in structure and excellent in working performance.

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
