Rapid repairing device for asphalt pavement cracks

Abstract

The invention discloses a rapid repairing device for asphalt pavement cracks. The repairing device comprises a repairing handle, an annular joint filling base device is mounted on the repairing handle, and a controller is mounted at one end above the repairing handle. A repairing material extrusion device is mounted in the center above the repairing handle, and a heat insulation and heat preservation heating device is arranged at the lower portion in the repairing handle. A driving motor drives an extrusion screw to rotate, so that an extrusion baffle extrudes a storage barrel, and the repairing material flows in a heating spiral coil at a constant speed. If the repairing material needs to be heated, a heat-conducting medium can be heated through an electric heating pipe, so that the repairing material is heated. The temperature of the repairing material can be effectively ensured to be constant through the uniform-speed movement of the repairing material and the heat transfer of the heat-conducting medium, so that the temperature of the repairing material can be accurately controlled, the effect of the repairing material for repairing the pavement cracks is better, and the repairing device can be suitable for various repairing 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...
