A vibrating and oscillating composite road roller steel wheel

Abstract

The invention discloses a vibrating and oscillating composite road roller steel wheel, which comprises a hollow wheel body, a hydraulic drive mechanism for driving the hollow wheel body, two wheel frames arranged symmetrically on the left and right sides of the hollow wheel body, The vibration shaft in the middle of the inner body and two symmetrically arranged on both sides of the vibration shaft, the vibration shaft is equipped with an overrunning clutch, the vibration shaft is equipped with a driven gear and the driven gear is connected with the overrunning clutch, and the outside of the vibration shaft is provided with an eccentric Mechanism; a left mounting plate and a right mounting plate are arranged symmetrically inside the hollow wheel body; a driving disc connected with a hydraulic drive mechanism is installed on the left mounting plate, and a clutch driving mechanism connected with the right end of the vibration shaft is mounted on the right wheel frame. The invention is simple in structure, reasonable in design, easy to use, good in use effect, flexible in use and operation mode, integrates vibration and oscillation functions, and can effectively solve the problem that the steel wheel of the existing road roller can only vibrate or oscillate.

Description

technical field [0001] The invention relates to a road roller steel wheel, in particular to a vibrating and oscillating composite road roller steel wheel. 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 are very important. [0003] Road rollers mainly include two types: vibratory rollers and oscillating rollers. The vibratory roller vibrates with the centrifugal force generated by the eccentric wheel, while the oscillating roller relies on the combination of the circumference of the oscillating wheel and the shaft core to form an elliptical oscillatory motion in the front and rear directions. accomplish. In actual use, the pressure wave of the vibratory roller can be transmitted to the depth, spread from ...

AI Technical Summary

Problems solved by technology

[0004] At present, the road rollers that appear at home and abroad are all independent vibratory rollers or oscillating rollers. There are few rollers that can vibrate and oscillate at the same time, and all of them can only achieve a single fixed amplitude, which is inevitable during the compaction process. Over-compacted or under-compacted ground will require repeated compaction, and the compaction method is too single, which cannot well meet the requirements of various working conditions

In this way, not only will the work efficiency be reduced, but also the cost will be increased, resulting in a waste of energy.
