Road roller combining vibration, oscillation and complex excitation as whole

Abstract

The invention discloses a road roller combining vibration, oscillation and complex excitation as a whole, which comprises a frame; an engine, a vibrating wheel, and a transmission part connected with the engine are disposed in the frame; a cab is disposed above the frame; the vibrating wheel comprises a vibrating wheel cylinder body; a center shaft is disposed at the center of the vibrating wheel cylinder body; four eccentric shafts are disposed around the center shaft with equal angles; the eccentric shafts are mounted on a supporting plate disposed on the vibrating wheel cylinder body; the end parts of the eccentric shafts are movably connected with driven pulleys; the driven pulleys are connected by a driving belt with driving pulleys which are disposed at the end part of the center shaft and at the same side as the driven pulleys; the driven pulleys are connected with a phase adjusting mechanism by gears at the end surfaces. The invention combines vibration, oscillation and complex excitation functions as a whole, enhances the application effect, expands the application scope, has a simple structure, is convenient for using, and is convenient for popularization and application.

Description

technical field [0001] The invention relates to a road roller, in particular to a road roller integrating vibration, oscillation and compound excitation. Background technique [0002] The function of the road roller is to make the materials of the subgrade and the structural layers of the road surface have sufficient compactness, thereby reducing the permanent deformation caused by driving, and enhancing its impermeability and stability. The service life and performance of roads are very important. [0003] In order to improve the compaction effect, the road roller has evolved from the early rolling static compaction to vibratory compaction and oscillatory compaction. The mainstream vibratory rollers on the market add an eccentric device to the central axis of the vibrating wheel. Its rotation causes the vibrating wheel to generate non-directional vibrations, thereby obtaining periodically changing exciting forces. Under the action of these exciting forces, the subgrade and...

Problems solved by technology

But at the same time, there are also the following disadvantages: when compacting the surface of the pavement, due to the action of the exciting force, the surface of the pavement is loose, the surface aggregate is crushed, and there are small construction cracks on the compacted surface.

However, the oscillating roller also has the defect of shallow compaction depth, so in most cases it is only used for compaction of thin-layer asphalt pavement
