The purpose of this utility model is to realize like this.The online amplitude modulated oscillations device of building block machine, be provided with casing, helical spline axle, helical spline endoporus gear, shift fork, eccentric block, straight line driving mechanism, belt pulley, helical spline axle, helical spline endoporus gear, shift fork, eccentric block are installed in the casing, helical spline endoporus gear is installed on the helical spline axle, eccentric block is installed on the vibrating shaft of helical spline axle head, belt pulley is connected the external part of helical spline axle, and shift fork connects helical spline endoporus gear and the straight line driving mechanism outer with being arranged on casing is connected.Controlling straight line driving mechanism as required back and forth promotes shift fork and helical spline endoporus gear is moved axially can carry out online amplitude modulation.
Described helical spline axle is four, and two is left-handed, and two for dextrorotation, and two adjacent installations of identical rotation direction, and the number of teeth of four helical spline endoporus gears installing on four helical spline axles equates and engagement in single file.Four helical spline axles are installed in parallel in the same horizontal plane or are installed in respectively in upper and lower two horizontal planes.Described casing is transmission case and vibrating bin, helical spline axle, helical spline endoporus gear and shift fork are installed in the transmission case, eccentric block is installed in the vibrating bin by the vibrating shaft that is connected with the helical spline axle head, is provided with power transmission shaft between helical spline axle and the vibrating shaft and is connected; Perhaps be combination box, helical spline axle, helical spline endoporus gear, shift fork, eccentric block are installed in the combination box, and eccentric block is directly installed on the helical spline axle.Described straight line driving mechanism comprises oil cylinder, cylinder, electric pushrod, Electrohydraulic push rod and linear electric motors.
The utility model is rational in infrastructure simple, manufactures easily, and the building block machine generally all has hydraulic system, and the straight line driving mechanism of online amplitude modulated oscillations device adopts oil cylinder, is provided with easy for installation.Eccentric block can be provided with the one or both ends that are connected the helical spline axle, and casing can be that transmission case and vibrating bin are provided with respectively, can also be the combination box that two combine into one.Easy for operation, vibrating device can be regulated its vibration force in operation process, realizes the purpose of online amplitude modulation, improves building block machine vibratory compaction effect and block forming efficient under different situations, and the excellent popularization using value is arranged.
Its operation principle is as follows:
When the contraction of oil cylinder piston bar, when being moved down into upper/lower positions vertically by four synchromesh gears of shift fork drive, the starting phase angle of four axles is 0, and the eccentric block on four vibrating shafts that promptly link with it all vertically downward.When power is imported via belt pulley, four beam warps are rotated in the mode that the adjacent shaft rotation direction is opposite synchronously by the synchromesh gear transmission, four vibrating shafts rotations that link with it.The centrifugal force horizontal component payment of two groups of vibrating shaft groups, the vertical component addition, the vibration force homophase of two groups of vibrating shaft groups, online amplitude modulated oscillations device obtains maximum vertical orientation vibration force.
When the oil cylinder piston bar stretches out, driving four synchromesh gears by shift fork moves up vertically, then helical spline endoporus gear forces left-handed two helical spline axles angle that moves in the direction of the clock, two dextrorotation by counterclockwise rotating an angle, caused the vibration force phase place of two groups of vibrating shaft groups that one difference is arranged, the vertical orientation vibration force that vibrating device obtains reduces.
When four synchromesh gears of shift fork drive were moved upwards up to uppermost position in fig-ure vertically, two groups of vibrating shaft group vibration force phase differences were 180 degree, and online in theory amplitude modulated oscillations device vertical orientation vibration force is 0.
