A rapid repair device for asphalt pavement cracks

Abstract

The invention discloses a quick repair device for asphalt pavement cracks, which comprises a repair handle, an annular caulking seat device is installed on the repair handle, a controller is installed at the upper end of the repair handle, and a The repairing material extruding device is equipped with a thermal insulation heating device under the inner part of the repairing handle. Drive the extrusion screw to rotate by driving the motor, so that the extrusion baffle squeezes the storage cylinder, so that the repair material flows at a constant speed in the heating spiral coil. If the repair material needs to be heated, the heat transfer medium can be heated by the electric heating tube. In this way, the repair material is heated, and the uniform movement of the repair material, combined with the heat transfer of the heat-conducting medium, can effectively ensure the constant temperature of the repair material, thereby accurately controlling the temperature of the repair material, and then making the repair material repair cracks on the road surface When the effect is better, and can be applied to a variety of repair materials.

Description

technical field [0001] The invention relates to the field of equipment related to road surface repair, in particular to a quick repair device for asphalt pavement cracks. Background technique [0002] Asphalt concrete pavement is widely used in road engineering because of its short maintenance time, high driving comfort, strong adaptability, and convenient maintenance. It is the main type of road pavement at present. However, asphalt concrete pavement often has various diseases due to various reasons, such as cracks, potholes, ruts and oil flooding, etc., which make the road damaged. If it is not repaired in time, the damage will be relatively large under the combined action of traffic load and water. Rapid development, resulting in an increase in maintenance costs and seriously endanger the safety of drivers and passengers, there is a greater safety hazard. [0003] In the patent CN201710999074.4 - an asphalt pavement repair device for municipal engineering, the repair mat...
