With the rapid development of the national economy and the continuous advancement of modern science and technology, it has created preconditions for the continuous progress of China's highway construction and maintenance, and the replacement of artificial labor by automated mechanical equipment has become an inevitable trend of social development. Especially in the field of construction and construction, high-efficiency, environmentally-friendly and reliable mechanical equipment has a very significant advantage over manual operations. It has become an important indicator for owners and supervisors to assess the construction quality, safety, environmental protection, progress and cost of the contractor. one. Dagang Road Machine conforms to the development trend of mechanized construction instead of manual operation, and independently develops the DK1800 self-propelled road widening machine, which is mainly for the sidewalk widening paving of the base material and asphalt mixture when the low-grade road is widened. A professional equipment with convenient operation, high degree of mechanization, efficient operation and strong power. The main function of the DK1800 self-propelled road widening machine is to receive the hopper to discharge the dump truck and transport it to the side paving area, and then spread the construction material in the construction area through the scraping device. Mainly used for grade asphalt pavement widening construction of cold materials (soil, water stabilized soil, aggregates, etc.) and hot asphalt mixture paving; road maintenance operations on the roadside targeted repair; roadside, roadside accompany Paving of earth or gravel. 1. Receiving and conveying device The belt is used to drive the conveying belt, and the speed is continuously adjustable; the rubber conveying belt with oil resistance, high temperature resistance and wear resistance can be used for paving clay, gravel and asphalt gravel; the receiving width can be applied to various dump trucks; 2, scraping device The maximum width of the scraper plate can reach 1.8m; the width and telescopic mechanism driven by the hydraulic cylinder can quickly adapt to the change of the width of the road; the adjustable height of the scraper mechanism is suitable for different construction depths; the angle of the scraper can be adjusted to suit different roads. Road arch requirements; 3, the driving system The driving drive system is equipped with a two-speed gearbox, which is equipped with a variable pump to make the working speed and driving speed steplessly adjustable; the full hydraulic steering system has flexible steering; the hydrostatic brake and the built-in brake of the drive axle ensure the brake is safe and reliable; 4, hydraulic system Large-capacity hydraulic fuel tank and high-power radiator can cope with various working conditions; large-displacement variable travel pump can provide maximum traction force of 30kN with driving system; 5, driving control system Side-mounted operation console, wide field of view, safe operation; reasonable layout of the operation console, can complete all operations of the construction; one person can operate, improve construction speed and reduce construction cost; Self-propelled road widening machine application advantages ⊙The use of widening machines for paving materials paving is a powerful complement to paver construction; ⊙ Higher construction speed, simplified operation saves time and construction costs; ⊙ widening machine to provide a new low-cost, high-efficiency road maintenance and construction method; ⊙The widening machine can be used to carry out targeted maintenance on the road surface, reduce the construction amount and extend the road overhaul cycle.
