Description
Technical field
The present invention relates to a kind of vibrator of vibrating roller with centrifugation lock.
Background technology
Vibrated roller in order to adapt to different operating modes, in vibration press by two kinds of amplitudes of big multi-configuration, i.e. large amplitude and small amplitude
The vibrating wheels of road machine use fluid motor-driven built with vibrator, vibrator, and amplitude is changed by changing the rotation direction of motor.
As illustrated in fig. 1 and 2, the principle of this vibrator is that two panels fixed eccentric block 2 is welded（But it is not limited to welding）It is living on main shaft 1
The dynamic empty set of eccentric block 3 has backing pin 4 on main shaft 1 between two panels fixed eccentric block 2, backing pin 4 is used for promoting movable eccentric block 3.It is different
Direction of rotation cause that movable eccentric block 3 and fixed eccentric block 2 are presented different phases, produce different eccentric moments with it is eccentric
Quality, then realizes different amplitudes.
During failure of oscillation, hydraulic motor drives fixed eccentric block 2 to slow down rapidly by main shaft 1, and movable eccentric block 3
It is in free deceleration regime in the presence of inertia, speed difference occurs between main shaft 1, fixed eccentric block 2 and movable eccentric block 3, activity
Eccentric block 3 can hit the backing pin 4 on fixed eccentric block 2, and the generation multiple impact that rebounds, and this shock can produce larger energy
Amount.During mostly occurring in road roller needs change compacting direction due to failure of oscillation, driver's operation vibrated roller slows down
And stop vibrating work, now clashing into the energy of generation can make the road surface that had been compacted produce ripple and the road surface that is difficult to repair to lack
Fall into.
The content of the invention
Regarding to the issue above, the present invention provides a kind of vibrator of vibrating roller with centrifugation lock, vibrated roller exciting
Main shaft, fixed eccentric block in device are locked and are integrated when rotated with movable eccentric block, in failure of oscillation, when rotating speed drops to necessarily
After degree, the potential energy of movable eccentric block shock backing pin is unlocked after weakening, and is locked with the process for unlocking without manual intervention.Avoid
Road surface to being compacted produces ripple and is difficult to the road surface defect repaired.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, the present invention is achieved through the following technical solutions：
A kind of vibrator of vibrating roller with centrifugation lock, including main shaft, are provided with two panels and fix eccentric on the main shaft
Block, is additionally provided with the movable eccentric block between two panels fixed eccentric block on the main shaft, set between two panels fixed eccentric block
It is equipped with the backing pin that can promote movable eccentric block, it is characterised in that the main shaft surface corresponding with movable eccentric block is provided with
First groove, is provided with movable block in first groove, the movable eccentric block is provided with the surface corresponding with main shaft
Second groove and the 3rd groove of movable block can partly be engaged.
It is preferred that, the first groove being radially arranged along main shaft.
It is preferred that, second groove and the 3rd groove are set along the centerline direction of movable eccentric block and the two is in 180 °
Phase.
It is preferred that, the U-shaped profile of first groove, the movable block is spherical in shape, second groove and the 3rd recessed
The cross section semicircular in shape of groove.
Or, the cross section of first groove is rectangle, and the movable block is pane, second groove and the
The cross section of three grooves is rectangle.
When not working, two fixed eccentric blocks are naturally drooped under gravity, and movable eccentric block is also naturally drooped, living
Motion block is fully located in the first groove under gravity.
When large amplitude is started working, hydraulic motor drive shaft clockwise and fixed eccentric block rotate, on fixed eccentric block
Backing pin promotion activity eccentric block rotation, movable block is rotated together with main shaft, and when reaching certain rotating speed, movable block is in centrifugal force
It is displaced outwardly under effect, in the first groove of main shaft, a part is located in the second groove of movable eccentric block a part, will
Movable eccentric block and spindle lock, then realize the locking of the phase of main shaft, movable eccentric block and fixed eccentric block.During failure of oscillation,
Movable eccentric block together slows down with main shaft, fixed eccentric block under the pining down of hydraulic motor, until rotating speed is reduced to movable block product
When raw centrifugal force is less than movable block weight, movable eccentric block is unlocked with main shaft, and now movable eccentric block is without enough potential energy
Go to clash into backing pin.
When small amplitude is started working, drive shaft that hydraulic motor is counterclockwise and fixed eccentric block rotate, and rotate certain angle
After degree, the backing pin promotion activity eccentric block rotation on fixed eccentric block, when reaching certain rotating speed, effect of the movable block in centrifugal force
Under be displaced outwardly, in the first groove of main shaft, a part is located in the 3rd groove of movable eccentric block a part, by activity
Eccentric block and spindle lock, the then locking of the phase of realization activity eccentric block and fixed eccentric block.During failure of oscillation, movable eccentric block
Together slow down under the pining down of hydraulic motor with main shaft, fixed eccentric block, until rotating speed is reduced to the centrifugal force of movable block generation
During less than movable block weight, movable eccentric block is unlocked with main shaft, and now movable eccentric block goes to clash into backing pin without enough potential energy.
The beneficial effects of the invention are as follows：
Vibrated roller allows main shaft, fixed eccentric block to be locked with movable eccentric block, it is to avoid rotating speed occur during failure of oscillation
Difference, so as to the energy of the larger shock that avoids movable eccentric block from being produced when can hit the backing pin on fixed eccentric block, reaching will not
Make the purpose of the road surface defect that the road surface that had been compacted produces ripple and being difficult to repair, improve the flatness on road surface.
