The specific embodiment
The utility model is described in further detail for following structure accompanying drawing.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, be provided with tamping plate 7 in frame 1 bottom, on tamping plate 7, be provided with vibrating bin 6, on vibrating bin 6, be provided with dynamical system 2, be provided with two parallel active eccentric shafts 8 and driven eccentric shaft 10 in the vibrating bin 6, initiatively eccentric shaft 8 is in transmission connection with dynamical system 2, on vibrating bin 6, be provided with hydraulic jack 11, the piston rod 15 of hydraulic jack 11 and eccentric shaft initiatively 8 are coaxial and extend to initiatively in the eccentric shaft 8, on piston rod 15, be fixed with commutation pin 14, driving gear 13 turning sets be contained on the eccentric shaft 8 initiatively and with fixedly be located at the transmission of intermeshing of driven gear 17 on the driven eccentric shaft 10, driving gear 13 endoporus are provided with two the symmetrical helicla flutes 16 corresponding with the pin 14 of commutating, on active eccentric shaft 8, be fixed with first eccentric block 12, on driven eccentric shaft 10, be fixed with second eccentric block 9, first eccentric block 12 and second eccentric block 9 differ 90 degree, be provided with the operating grip 4 of adjustable-angle on frame 1, the control system 3 of hydraulic jack 11 is located on the operating grip 4.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 5 and Fig. 6, dynamical system 2 drives initiatively eccentric shaft 8 rotations during work, initiatively eccentric shaft 8 drives driven eccentric shaft 10 rotations by the driving gear 13 and the driven gear 17 of the transmission of intermeshing, first eccentric block 12 and second eccentric block 9 differ 90 degree and produce vibration, the dull and stereotyped rammer in the real-time unidirectional walking of vibro-rammer; When needing commutation, the control system 3 of hydraulic jack 11 on the manipulation operations handle 4, hydraulic jack 11 promotes piston rod 15 motions, commutation pin 14 on the piston rod 15 carries out straight line simultaneously and rotatablely moves at symmetrical helicla flute 16, thereby drive driving gear 13 relative first eccentric block, 12 Rotate 180 degree, thereby make first eccentric block 12 and second eccentric block, 9 relative positions also rotate 180 degree, realized that dull and stereotyped rammer oppositely walks.
Referring to Fig. 1 and Fig. 4, when need are mobile detachable mobile wheel system 5 is installed on the frame 1, then by artificial dilatory the transfer; During work detachable mobile wheel system 5 taken off and put aside.A people is promptly transferable for more than 300 jin equipment.
Referring to Fig. 1, Fig. 2 and Fig. 3, on operating grip 4, operate the control system 3 of hydraulic jack 11 during work by operating personnel, promote piston rod 15 by hydraulic jack 11, piston rod 15 carries out straight line simultaneously and rotatablely moves under symmetrical helicla flute 16 constraints then, thereby the driving gear 13 and first eccentric block 12 relatively rotate on the promotion active eccentric shaft 8, reach the commutation purpose; After hydraulic jack 11 unloadings, commutation pin 14 automatically resets under the effect of inertia force.The advantage of hydraulic control system is: this system has the advantage of hydraulic system, promptly dependable performance, fault rate is low, the life-span is long.Even hydraulic system breaks down, equipment can also be toward a direction walking.And the traditional theory exchange system when breaking down equipment just can not walk.
Referring to Fig. 1, Fig. 2 and Fig. 3, commutation pin 14 is under the control of hydraulic system and under the acting in conjunction of inertia force, initiatively the driving gear 13 on the eccentric shaft 8 can and active eccentric shaft 8 on the optional position of relative position between 180 degree of first eccentric block 12 stop, thereby the vibration force that first eccentric block 12 and second eccentric block 9 are produced make a concerted effort in the horizontal direction with vertical direction on the size of component change with the different of position, its pace also correspondingly changes.When the speed of travel is fast material compacting power is reduced, when the speed of travel is slow material compacting power is increased, it is to being tamped the active force maximum of material during the vibration of original place.Widened the scope of application of equipment so greatly.Its advantage:, can advance fast to raise the efficiency, as materials such as compacting pitch, grit when being compacted material easily during compacting.When being compacted material and being difficult for compacting, can advance at a slow speed even pressure is rammed in the original place for a long time, to reach higher construction requirement, as materials such as compacting earth.The vibration frequency that domestic classic flat-plate is rammed is generally at per minute 4000 times or lower, and vibration frequency of the present utility model is per minute 5400 times, improved nearly 40%, thereby nearly 2 times of stressed raisings during granular material work.
The utility model is suitable China's actual conditions, can large-scale promotion uses, can satisfy the light-duty compacting instrument that different kinds of roads are built and maintenance is used.
