As shown in fig. 1-2, an asphalt concrete pavement compacting and leveling device comprises an asphalt mixing truck 1, a compacting mechanism 4 and a leveling mechanism, wherein the compacting mechanism 4 and the leveling mechanism are arranged on the asphalt mixing truck 1; the compaction mechanism 4 comprises a frame connected to the asphalt mixing skip 1, a compaction seat plate arranged on the frame, and a driving oil cylinder for driving the compaction seat plate to reciprocate; the compaction seat plate comprises a base plate 6 and reinforcing plates 7, and the reinforcing plates 7 are detachably connected to two sides of the base plate 6 through bolts; and the levelling means is arranged behind the compacting means 4.
Compared with the prior art, the construction of the asphalt concrete road in the prior art mainly comprises the reconstruction of a new road or an old road, or the maintenance and filling operation of the asphalt concrete road surface and the like can be applied to a leveling device. In the prior art, many leveling devices are mainly applied to the compression roller to compact and level the asphalt mixture, but because asphalt is paved and needs to be heated, the asphalt mixture in a heating state has good fluidity and plasticity, but the asphalt mixture in a heating state inevitably has more bubbles, the asphalt mixture is simply compacted and leveled by the compression roller, the problem of uneven in the leveling process is solved, the whole leveling effect is poor, and the paved asphalt mixture is easy to crack and bulge in the later stage. Therefore, the pre-compaction operation is needed before the leveling of the press roller, the bubbles and the moisture of the asphalt mixture are extruded, and the leveling effect of the asphalt mixture is improved, however, the structure of the existing pre-compaction operation mechanism is fixed, so that the asphalt mixture is accumulated to two sides of a road during the pre-compaction operation, particularly, the reserved road surface is low in height in the old road reconstruction process, and finally the asphalt mixture overflows to two sides of the road. In the utility model, the provided compacting and leveling device for the asphalt concrete pavement is respectively provided with the compacting mechanism 4 and the leveling mechanism, and the provided compacting mechanism 4 can enlarge the width of the compacting mechanism 4 by adding the reinforcing plates on the two sides of the base plate 6, so that the same compacting operation can be carried out on the pavement edge under special conditions, and the asphalt mixture can be prevented from piling up on the two sides. In the new road paving process, the reinforcing plate 7 can be removed as well, and normal compaction operation can be performed.
The leveling mechanism comprises a leveling roller 5 and a leveling shaft, and the leveling roller 5 is connected to the tail of the asphalt mixing vehicle 1 through the leveling shaft.
The compacting mechanism 4 further comprises a screed 3, the screed 3 being mounted to the frame, and the screed 3 being arranged in front of the compacting shoe and close to the ground. The asphalt mixing vehicle 1 includes an asphalt storage hopper 2, and an output port of the asphalt storage hopper 2 is provided in front of a compacting mechanism 4. The output ports are a plurality of, and are uniformly distributed at the bottom of the asphalt mixing skip 1. The screed 3 can better evenly lay down the asphalt mixture after asphalt discharge.
The two sides of the base plate 6 are provided with connecting protrusions 8, and one side of the reinforcing plate 7 is provided with a connecting pair matched with the connecting protrusions 8. The width of the compaction seat board can be adjusted by a detachable connection mode.
In actual use, the asphalt concrete pavement compacting and leveling device provided by the utility model can be used in different states according to specific needs, and the compacting mechanism 4 does not need to be widened when a new road is paved. The width of the base plate 6 is directly applied to the base plate, the compacting mechanism 4 is driven to carry out repeated extrusion operation through the repeated motion of the driving oil cylinder, and the leveling roller 5 is driven to move to carry out left-rear leveling operation through the movement of the vehicle. When the old road is reformed, because the additional paving operation is carried out on the old road surface or the old asphalt road surface maintenance and seam repair operation is carried out, the fact that asphalt is easily accumulated on two sides of the road is needed to be considered, the additional paving operation can cause the defect of the original road edge height, and finally asphalt mixture overflows two sides of the road is caused. Therefore, the reinforcing plates 7 are required to be added on two sides of the base plate 6, the width of the compacting mechanism 4 is adjusted through the reinforcing plates 7, and meanwhile, the asphalt mixture can be more uniformly distributed by performing extrusion operation on the edges of the road, so that the problem of overflow after stacking is avoided.
The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
