The road surface flatness repair machine to be installed on the road to be fixed on the road according to the drawings to install, and adjust the amount of feed. As the road specification requirements, with 3 m ruler detection, and its gap with the road height of more than 3mm is unqualified. Combined with this specification requirements, first of all the road surface roughness of the two longitudinal track made of the same height, the traction mechanism for the four groups of drive wheels, each drive wheel, respectively, through the joint bearing shaft and support universal connection, Each set of drive wheels for the two drive wheels, the role of the walking wheel will be the original smoothness of the road weakened and the average surface of the bump surface of the peak, and then reflected to the longitudinal track, work trolley and transverse orbit in the longitudinal orbit forward and backward movement The length is also set at 3 meters. In the case of road surface formation, the vertical height of the front and rear rails of the cylindrical row of the work car is set to 0 to 3 mm, the sensitivity can be adjusted, the smaller the value, the deeper the infeed , The higher the flatness of the flatness after milling. Work, the road roughness repair machine as a whole is very slow, generally 0.3 ~ 1 m / min speed forward, while the work car and horizontal track together to 2 to 4 times the speed, usually 2 ~ 85 m / min speed Along the longitudinal track to move the road surface, the work of each car to complete a 3 meters long longitudinal face after the lateral movement of a knife head position reverse movement cutting, so reciprocating and lateral movement work, milling work is forward Advance. In the work of each car to move the work of a round-trip time, the machine forward distance is less than 3 meters, otherwise there will be jumping work dead zone, to ensure that each position of the road by the work car repeatedly cut more than twice. In the case of work, in case of road turn, through the inverter to adjust the walking speed of the left and right sides of the walking wheel to achieve the turn. PLC can be based on the size of the current motor to adjust the horizontal track speed, control chip speed, to prevent motor overload. The power source of the road flatness repair machine is an external generator set. bench milling machine for sale heavy construction machinery patching concrete basement cracks asphalt sealing information
