Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway maintenance equipment, in particular to a highway maintenance pavement crack filling device. Background Art
[0002] After a highway is built and opened to traffic, its quality will gradually decline due to the wear and impact of wheels, erosion and weathering by natural forces such as rainstorms, floods, sandstorms, ice and snow, sunlight, ice melting, as well as human damage and certain defects left over from construction. Therefore, after a highway is built and opened to traffic, maintenance measures must be taken and it must be continuously updated and improved. Highway maintenance must repair damaged parts in a timely manner, otherwise it will lead to increased investment in repair projects, shorten the service life of the highway, and cause losses to road users.
[0003] When cracks appear on a road due to the squeezing of heavy-loaded vehicles, the two sides of the road will separate and gaps will appear on the road. If the gaps are not dealt with in time, the scope of road damage will expand. Therefore, it is necessary to use grouting devices to deal with the gaps on the road in time.
[0004] When using existing grouting devices, a conical gun head is often inserted into the gap, and then high-strength cement slurry is poured into the gap through a pipe and the conical gun head until the gap is filled with cement slurry and overflows on the road surface. A fence is set outside the grouting part, and the fence is recovered after the cement slurry solidifies to complete the grouting operation. In actual use, it is found that due to the difference in the width of highway gaps, after the conical gun head is inserted into the gap, if the gap width is significantly larger than the gun head width, the pressure of the cement slurry filled is limited and cannot flow deep into the gap, resulting in poor grouting effect, which in turn leads to limited highway maintenance grouting effect. For this reason, we propose a highway maintenance pavement grouting device. Utility Model Content

The rubber sheet 13 has a certain elastic deformation ability. After the rubber sheet 13 is inserted into the gap in the road, the edge side of the rubber sheet 13 can be deformed to one side to ensure that the edge side of the rubber sheet 13 is tightly fitted with the gap, thereby separating the internal space of the gap, and distributing and filling the separated intervals, thereby greatly improving the filling effect.
[0027] Specifically, the sliding assembly includes vertical grooves symmetrically arranged on the inner circumference of the arc-shaped guide tube 6, and limit rods 16 are inserted and fixed in the vertical grooves. A limit ring 15 is slidably arranged between the outer circumferences of the limit rods 16, and the conical gun barrel 14 is fixed on the inner circumference of the limit ring 15.
