Vibration and oscillation composite type road roller steel wheel

Abstract

The invention discloses a vibration and oscillation composite type road roller steel wheel which comprises a hollow wheel body, a hydraulic driving mechanism, two wheel racks, a vibration shaft and two oscillation shafts, wherein the hydraulic driving mechanism is used for driving the hollow wheel body; the wheel racks are symmetrically arranged on the left side and the right side of the hollow wheel body; the vibration shaft is mounted in the middle of the inner side of the hollow wheel body; the oscillation shafts are symmetrically distributed on two sides of the vibration shaft; an overrunning coupler is mounted on the vibration shaft; driven gears are mounted on the oscillation shafts and are connected with the overrunning coupler; eccentric mechanisms are arranged on the outer sides of the oscillation shafts; a left mounting plate and a right mounting plate are symmetrically arranged inside the hollow wheel body; a driving disc which is in transmission connection with the hydraulic driving mechanism is mounted on the left mounting plate; a clutch driving mechanism in transmission connection with the right end of the vibration shaft is mounted on the right wheel rack. The vibration and oscillation composition road roller steel wheel is simple in structure, reasonable in design, simple and convenient to operate, good in use effect and flexible in use and operation mode, vibration and oscillation functions are integrated, and the problem that a conventional road roller steel wheel can only vibrate or oscillate can be effectively solved.

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.
