The mechanism is composed by vibration wheel, vibration bearing, big vibration shaft, small vibration shaft, amplitude-modulating device, connecting shaft with helical groove, amplitude-modulating oil cylinder, locking oil cylinder and friction plate. The amplitude-modulating oil cylinder inside the vibration wheel connects with the amplitude-modulating device. The small vibration shaft is housed inside the big vibration shaft, and the connecting shaft with helical groove is housed inside the small vibration shaft. The front end of the connecting shaft with helical groove passes through the vibration bearing and connects with the amplitude-modulating device. The rear end of the connecting shaft with helical groove passes through the friction plate, dish type spring and press cover and connects with the locking oil cylinder. The mechanism can be adjusted at will between the minimum and maximum vibration amplitudes which applies to compaction of different speadings and different materials, can easily realize the function of same vibration direction as the traveling direction of the road roller, can improve compacted surface quality. The mechanism is of simple structure and is easy to be manufactured, provides high operation efficiency, and high levelness of compacted road surface, is not liable to produce over-compacted road surface or break aggregates.
Description
Technical field
The utility model relates to a kind of vibratory compaction amplitude modulation apparatus of road roller.
Background technology
The important technological parameters of well-known road roller vibratory compaction is exciting force and amplitude, reasonably amplitude can significantly improve compaction quality, now more and more people have recognized progressively that the equipment of road roller should have the selection of more amplitudes, and amplitude should easier control and adjustment.At present, the vibrating device of road roller generally all adopts fixed eccentric block and movable eccentric block, realize two kinds of amplitudes by rotating, though many amplitudes device is also arranged, but can not adjust arbitrarily, therefore, the compacting of different shops layer and different compacting materials can not be adapted to fully, very high compactness can not be reached.
Summary of the invention
The purpose of this utility model provides a kind of road roller that can make and adjusts the telescopic amplitude modulation mechanism that amplitude adapts to different shops layer and different compacting material compactings arbitrarily.
The purpose of this utility model is achieved in that this mechanism is made up of vibrating wheels, vibration bearing, big vibrating shaft, small vibration axle, amplitude modulation apparatus, band spiral fluted connecting axle, amplitude modulation oil cylinder, locking cylinder, friction plate, amplitude modulation oil cylinder in the vibrating wheels connects amplitude modulation apparatus, be with the small vibration axle in the big vibrating shaft, be with band spiral fluted connecting axle in the small vibration axle, band spiral fluted connecting axle front end passes vibration bearing and connects amplitude modulation apparatus, and band spiral fluted connecting axle rear end is passed friction plate, disk spring and gland and is connected locking cylinder.
This mechanism utilizes the amplitude modulation oil cylinder to promote amplitude modulation apparatus and realizes rectilinear motion, the rectilinear motion of amplitude modulation apparatus drives the rotation of small vibration axle by band spiral fluted connecting axle, realize that big vibrating shaft and small vibration axle shape have a certain degree, so big or small vibrating shaft synthesizes new eccentric throw, form new amplitude, so just can adjust amplitude according to different needs; If the designed size vibrating shaft such as is at quiet eccentric throw, just can obtain from 0 to the adjustment the design maximum, satisfy the requirements of various shops layer.This mechanism is converted to rectilinear motion by helicla flute and rotatablely moves, thereby change the eccentric throw that the eccentric block phase place is adjusted eccentric block, thereby change the size of entire mechanism amplitude, the size of corresponding change exciting force, the compacting operation that adapts to different compacting materials and different-thickness, can can adapt to compacting operation by the adjustment of amplitude size, can also improve the compacting planeness, can prolong the life-span of bearing and rubber absorbers.
Because the utility model adopts said structure: can adapt to the compacting operation of different shops layer and different materials in minimum to adjusting arbitrarily between the peak swing, not have power loss; Realize direction of vibration and the consistent function of road roller enforcement direction easily, can improve the compacting surface quality.The utility model is simple in structure, is easy to make, and the operating efficiency height, compacting surface planeness height is difficult for producing overcompaction or smashing the aggregate phenomenon.
