Multifunctional bituminous pavement hot repair machine

Abstract

The invention relates to a multifunctional bituminous pavement hot repair machine. The multifunctional bituminous pavement hot repair machine comprises a heater (2) internally provided with an infrared radiation wire face (1). A mixing chamber (3) is arranged at the front end of the heater (2). An electromagnetic valve (4) is arranged between the heater (2) and the mixing chamber (3). A thermodetector (5) is arranged in the heater (2). The electromagnetic valve (4) is switched on and off according to temperature information detected by the thermodetector (5). The multifunctional bituminous pavement hot repair machine provided by the invention is simple to operate, small in energy consumption, good in repair quality, high in safety and capable of meeting the requirements of city roads and damage construction of manhole covers.

Description

technical field [0001] The invention relates to a kind of repairing and maintenance mechanical equipment for asphalt pavement and surrounding diseases of manhole cover, more precisely, it is a multifunctional asphalt pavement hot repair machine, which is the preferred equipment for the construction of urban road and manhole cover disease. Background technique [0002] Asphalt 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 pavement often has various diseases due to various reasons, such as cracks, potholes, ruts, and oil flooding, which make the road damaged. If it is not repaired in time, the damage will be faster under the combined action of traffic load and water. Development, resulting in an increase in maintenance costs and seriously endanger the safety of drivers and passengers, there is a greater sa...

Problems solved by technology

[0004] At present, the hot repair machines used in the market have the following defects: 1) The fixed heating wall is used and the heating area is limited. When repairing long or large road surface diseases, it needs to be heated in batches

2) When repairing the road surface disease around the manhole cover, the manhole cover is often covered with high-temperature resistant cotton and then heated to avoid the aging of the manhole cover due to high temperature. Of course, it will cause a lot of energy waste and increase energy consumption; 3) from heating From the effect point of view, the existing patching machines in the market have poor infrared radiation penetration ability and low heat conversion efficiency, which may easily cause the surface temperature to be too high and the bottom temperature to be low, which will cause charred and carbonized asphalt materials, destroying the physical and mechanical properties of asphalt materials, thus Failure to achieve the purpose of hotfix
