Quick vibration and tamping mechanism of asphalt for road and bridge construction, using method and asphalt paver of same

Abstract

The invention discloses a quick vibration and tamping mechanism of asphalt for road and bridge construction, and a using method and an asphalt paver of the same, and relates to the technical field of road construction. The quick vibration and tamping mechanism comprises a support seat, a vibration and tamping plate, a lug and a driving wheel. The vibration and tamping plate is arranged on the lower part of the support seat and moves vertically, and the driving wheel is rotatably connected with the support seat. The lug is arranged on the lower part of the driving wheel, and the bottom of the lug is connected with the upper part of the vibration and tamping plate. The driving wheel drives the vibration and tamping plate to perform vibration of different strengths through the lug. The vibration and tamping plate tend to move upward in the absence of external force. The quick vibration and tamping mechanism of the asphalt for the road and bridge construction is capable of performing vibration of different strengths on a same asphalt layer, further performs vibrating and tamping on the asphalt layer, facilitates exhausting of air from the asphalt layer and further facilitates quick tamping of the asphalt layer, thereby avoiding over-vibration and damages to edges of surface pellet materials. The quality of an asphalt pavement is guaranteed and the life cycle of the asphalt pavement is prolonged. The quick vibration and tamping mechanism of the asphalt for the road and bridge construction has the advantages of being simple in structure, reasonable in design and easy to manufacture.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a rapid vibrating mechanism for road and bridge construction asphalt, a use method and an asphalt paver. Background technique [0002] Modern road transportation has continuously improved requirements for road surface strength, stiffness, compactness, uniformity, and smoothness, driving comfort, high speed, and safety; and under the current mechanism of China's transformation period, it will bring new challenges to construction mechanization. The rapid development has come, so as the main product of the black road construction machinery that mainly undertakes the Chinese road network, the paver shows a high-speed development trend and is favored by the construction machinery industry. [0003] After the asphalt paver paves the asphalt-covered road surface, it needs to be vibrated, and the vibration process is time-consuming. When laying asphalt pavement, alth...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problems of long time spent, poor vibration quality and low efficiency existing in the prior art, the present invention provides a rapid vibration mechanism for asphalt in road and bridge construction, its use method and its asphalt paver, which can pass through the same The asphalt layer is vibrated with different intensities, and then the asphalt layer is vibrated, which is beneficial to discharge the air in the asphalt layer, and then helps to quickly vibrate the asphalt layer. At the same time, it is also beneficial to avoid over-vibration and surface vibration. The water chestnut of the pellets is damaged, which ensures the pavement quality of the asphalt pavement and is beneficial to improve the service life of the asphalt pavement
