Description
Technical field
In order to guarantee the construction quality of road; Before road deck is built; Need to design to the proportioning of concrete service condition to asphalt, in design process, the asphalt proportioning that primary design is different usually also is compacted into bitumen mixture specimen respectively according to the rules.But the forming method of the test specimen compaction moulding method of laboratory asphalt and real road asphalt has bigger difference.The driving wheel of street roller produces tractional force to asphalt; The road surface of real road is provided with the gradient; And tractional force changes along with the variation of the longitudinal gradient gradient; The test specimen compaction moulding of laboratory asphalt does not reflect the variation of street roller tractional force in the actual making road that is provided with the gradient; Cause the textural difference of bitumen mixture specimen structure and actual making road bigger like this, indexs such as the test specimen rut of laboratory moulding, dynamic stability can not reflect actual conditions, and influence is to the optimal selection of asphalt proportioning.
Background technology
The utility model relates to a kind of asphalt test compaction moulding equipment, specifically is a kind of asphalt compaction moulding machine.
Summary of the invention
The utility model provides a kind of asphalt compaction moulding machine in order to reflect the forming method of actual laying of roadway medium pitch compound.
The utility model is to adopt following technical scheme to realize: a kind of asphalt compacting machine; Comprise frame, be located at the circular arc rolling wheel of frame below; The forward and backward both sides of the end face of circular arc rolling wheel are provided with former; The former upper end is suspended on the frame, also comprises arc resistance tooth bar, pump oil structure; Said frame below is provided with erecting frame between two disc of circular arc rolling wheel, and the said erecting frame below of going up is provided with down erecting frame; The left and right sides is equipped with supporting traverse between two disc of described circular arc rolling wheel; Described arc resistance tooth bar across and be fixed between two supporting traverses; Described arc resistance tooth bar is provided with the resistance gear that is meshed with it; Described resistance gear kink is on axle, and said axle is supported in down the below of erecting frame; Said pump oil structure comprises fuel tank, and oil cylinder is placed in in-oil cylinder piston, and the downside of connection piston is provided with the connecting rod of tooth; The bottom of said fuel tank offers first oil-in; Have first oil-out on the said oil cylinder; Be connected through surplus valve between said first oil-in and first oil-out; The bottom of said fuel tank offers second oil-out, has second oil-in on the said oil cylinder, is connected through unidirectional input pressure operation valve between said second oil-out and second oil-in; Described oil cylinder is located at the below of erecting frame, and described connecting rod is meshed with the resistance gear.
During concrete work; Be arranged at die trial on the testing table when left movement, the circular arc rolling wheel is accordingly to left movement, and the arc resistance rack drives resistance gear that is fixed between two supporting traverses turns clockwise; Because of the resistance gear is meshed with the connecting rod that has tooth; Piston inwardly is pressed into oil cylinder, produces malleation in the oil cylinder, and surplus valve is opened; Hydraulic oil is passed through first oil-in inflow fuel tank (form the rotary damping to the resistance gear, finally the circular arc rolling wheel is produced damping) of fuel tank by first oil-out of oil cylinder; When die trial moves right; The circular arc rolling wheel moves right accordingly, and arc resistance rack drives resistance gear is rotated counterclockwise, and connecting rod and piston are pulled outwardly out oil cylinder; Produce negative pressure in the oil cylinder; Unidirectional input pressure operation valve is opened, and hydraulic oil is passed through second oil-in inflow oil cylinder (form the rotary damping to the resistance gear, finally the circular arc rolling wheel is produced damping) of oil cylinder by second oil-out of fuel tank.Because of die trial is shuttle motion, the present invention is periodic cycle according to this, surplus valve, the alternation of unidirectional input pressure operation valve, and to the damping that rotates of resistance gear, and finally to the damping that rotates of circular arc rolling wheel.
During concrete the use; Because of the driving wheel of street roller produces tractional force to asphalt; The road surface of real road is provided with the gradient, and when go up a slope in gradient road surface, the driving wheel of street roller is littler than the tractional force that produces on the level road to the tractional force that asphalt produces; And tractional force changes along with the variation of the longitudinal gradient gradient; According to pavement behavior in the paving process, adjust circular arc through surplus valve between control adjustment oil cylinder and the fuel tank and unidirectional input pressure operation valve and roll damping (resistance), thereby the driving wheel of simulation street roller is to the tractional force of the asphalt that is provided with gradient road surface test specimen in the die trial.The adjustment of surplus valve and unidirectional input pressure operation valve is those skilled in the art's common practise and realizes easily between oil cylinder and the fuel tank.
The utility model novel structure, be skillfully constructed; The variation of the tractional force that the driving wheel that can simulate street roller produces the asphalt that is provided with the different gradient road surface; The bitumen mixture specimen structure can reflect the structure of actual making road asphalt compound, and indexs such as the rut of the test specimen of laboratory moulding, dynamic stability can reflect actual conditions, thereby select the best proportioning of asphalt; The making that is used for real road, the serviceable life on prolongation road surface.
