Road repairing device

Abstract

The invention belongs to the technical field of pavement repairing devices, Specifically, the invention relates to a road repairing device, comprising a frame, a traveling wheel, a puncture unit, a crushing unit, a stuffing box and a rolling roller, wherein the puncture unit is installed on the frame, and the puncture unit is used for knocking the edge of the damaged pavement to determine the range of the damaged pavement, and simultaneously avoiding damage to the intact pavement during the repairing process; The crushing unit is installed on the vehicle frame, the crushing unit is located behind the puncture unit, and the crushing unit is used for completely crushing the damaged road surface knocked by the puncture unit; The stuffing box is used for adding asphalt to the pavement to be repaired after being crushed by the crushing unit according to the actual needs and repairing the pavement again; The rolling roller is installed under the vehicle frame, the rolling roller is located behind the stuffing box, and the rolling roller is used for rolling the pavement and repairing the pavement. The invention greatly improves the repairing efficiency, and at the same time, the crushed asphalt is heated and reused, thereby reducing the cost.

Description

technical field [0001] The invention belongs to the technical field of road repairing devices, in particular to road repairing equipment. Background technique [0002] In high-grade highways, asphalt pavement is valued by countries all over the world for its well-known good performance. , no dust, small vibration, low noise, short construction period and easy maintenance and repair, etc., are widely used in expressways. With the development of highways in my country and the increase of traffic volume, rutting is the main form of damage to asphalt pavement. Rutting is the accumulation of permanent deformation in the vertical direction of the wheel track belt on the roadway under repeated wheel loads. When it is serious, there are usually bulging deformations on both sides. It is mainly caused by viscous flow of asphalt mixture, deformation of soil foundation and base course, and includes a certain degree of compaction and material wear.

Problems solved by technology

[0004] In the above-mentioned patent documents, the road surface is first ground, and then the asphalt after grinding and pulverization is heated on-site by an electric heating plate to melt the asphalt, and after the asphalt is melted, it is compacted by rolling rollers to complete the repair of the road surface; the grinding roller used in this scheme During the grinding process, the grinding range cannot be adjusted according to the size of the damaged road surface, and it is easy to simultaneously polish the intact road surface, resulting in waste
