Simulation is completed in the static pressure reality of plate tank test auxiliary material and vibrating compacting.Lifting cylinder lift carriage and vibrating wheels are controlled, then
Whole device orbital motion is controlled by assistant drive device, leaks out template box, you can completes the replacement of material, carries out different materials
Vibrating compacting experiment;The road roller vibrating compacting examination of different tonnages can be carried out by adding or reduce different rack clump weights
It tests;The road roller vibrating compacting experiment of various amplitude specification can be carried out by adding or reduce different wheel body clump weights.
Description of the drawings
Fig. 1 is the schematic front view of one embodiment of the invention.
Specific implementation mode
As shown in Figure 1, this vibrating compacting experimental rig disclosed in the present embodiment, it includes track 1, movable stand 2, rack
3, main drive 4, assistant drive device 5, vibrating wheels 6 and template box 7.Wherein template box 7 is dismountable rectangular box, outside
Wall is equipped with the connection ring 71 convenient for handling, and track 1 is arranged in the both sides of 7 a pair of sidewalls of template box, and movable stand 2 is arranged in track
On, vibrating wheels 6 are connected to 3 downside of rack by hanger bracket 8, are located in template box 7.
Movable stand 2 includes four columns 21, and the bottom end of each column 21 is equipped with idler wheel 22, and rack 3 passes through lifting cylinder 23
It is connect with the top of column 21, guide and limit wheel group 24 is additionally provided between rack 3 and column 21.Movable stand 2 by idler wheel 22 with
Track 1 connects, and driven sprocket 25 is fixed with outside the idler wheel 22 at assistant drive device 5.The upside of rack 3, which is equipped with, places rack counterweight
The loading frame 9 of block, downside are connect by hanger bracket 8 with the main shaft of vibrating wheels 6, and hanger bracket 8 is stretched out in two outer end of main shaft of vibrating wheels 6
Outside, it is wheel body counterweight construction section.Main drive 4 includes the plunger variable hydraulic pump being located in rack 3, driving motors and shakes
Dynamic motor, plunger variable hydraulic pump make vibrating wheels 6 rotate and vibrate, main driving to driving motors and vibrating motor offer power
Device is located at the upside of the rack.
Assistant drive device 5 includes sequentially connected three phase electric machine, speed reducer and arrangement of clutch, is led to outside the output shaft of speed reducer
It crosses arrangement of clutch and is connected with drive sprocket 51.
The present embodiment needs addition rack clump weight and wheel body to match according to experiment first when carrying out vibrating compacting experiment
Pouring weight;Then by lifting cylinder lift carriage and vibrating wheels, auxiliary material to be pressed is put into template box;Then pass through lifting cylinder
Control vibrating wheels are contacted with auxiliary material;Vibrating wheels spin and up-down vibration are controlled by main drive again, realized in template box
The vibrating compacting of auxiliary material is tested, the simulation of an operating mode is completed.When needing to carry out the compaction test of other materials, control lifting oil
Then cylinder lift carriage and vibrating wheels control whole device orbital motion by assistant drive device, leak out template box, you can complete
At the replacement of material;When needing to carry out the road roller vibrating compacting experiment of different tonnages, only different racks need to be added or reduced
Clump weight;When needing to carry out the road roller vibrating compacting experiment of various amplitude specification, only different wheels need to be added or reduced
Body clump weight.

Control and the interference that mutually drives of while preventing main drive or assistant drive device from acting on.
By the way that movable stand is set as four columns frame framework, convenient for keep rack balance in the horizontal plane and be unlikely to around
Vibrating wheels spindle swing, convenient for keeping the even running of complete machine.
It is set as roller type by the contact movable stand with track, reduces running resistance, convenient for keeping vibrating compacting experiment
Emulation.
By the way that template box is set as dismountable babinet, and it is equipped with the connection ring for handling outside the enclosure, convenient for experiment
The cleaning of auxiliary material is convenient in the transfer and transport of device.
