Dual-drive road leveler concrete paver
Concrete pavement paver can be widely used in various highways, Construction of concrete projects such as municipal roads, squares, airport runways, etc. Different models and different lengths of pavers can be customized according to the length of the road. Detailed explanation of the construction principle of the concrete pavement paver (three-roller axis)
The concrete pavement paver (three-roller axis) has the functions of vibration density, paving, slurry lifting and The main part of the leveling function is an eccentric vibration shaft that plays the roles of vibrating, paving, and lifting pulp, and two central axes that drive leveling. The vibrating shaft always rotates backwards, while the other two pins can rotate forwards and backwards.
// Meter roller vibrating beam
When the concrete pavement paver (three-roller shaft) is working, the machine moves forward, the vibration axis rotates backward, and at the same time, through eccentric vibration, the mixture is liquefied and vibrated The shaft cuts into the liquefied mixture under the action of its own weight and power, and squeezes forward to throw out the mixture, thereby performing the functions of paving, vibrating density, and pulp lifting. The central vibration of the vibration axis causes regular waves to be formed on the surface of the mixture. At the same time, when the slump of the deconcrete mixture is small or the cloth height is too high, there will be too much mixture accumulated in front of the vibration axis. When the three-roller machine moves forward, it will be blocked and cause a climbing phenomenon. Causes unevenness on the surface of the mixture. The two rear axes roll flatly on the template to eliminate this unevenness and realize the entire function. When the concrete paving machine (three-roller axis) moves forward, the waves formed after the vibration will fly up and be eliminated by the two entire axles behind it. However, when moving backward, the waves formed by the vibration can only be eliminated when the three-roller machine turns around. If the three-roller machine cannot turn around in time, the waves formed will remain on the surface of the mixture, thus affecting the quality of the road surface. . Therefore, the construction advantages of the concrete pavement paver (three-roller axis) that must be adopted during construction include forward vibration and backward static rolling
The body is light, the operation is simple and flexible, and it has strong paving ability. If the material supply is sufficient, the paving speed can reach 1.5 meters. The concrete pavement paver (three-roller shaft) may be unable to reach the set speed and amplitude due to long-term wear and tear, or bending deformation may occur, causing waves on the road surface. , cannot meet the flatness requirements, so regular inspection and maintenance must be paid attention to
