Summary of the invention
The objective of the invention is to provide for the deficiency of the technology that overcomes existing experiment of weighing platform and under a kind of puzzled volume state motor train unit is weighed and transfer spring to pretend the intelligent accent spring testing table of industry.The present invention can eliminate the influence of two pairs of tested vehicles of motor train unit front and back car, accurately calculates the accent spring amount that each transfers the spring position, and accomplishes simulation accent spring.
In order to achieve the above object, technical scheme of the present invention is: a kind of intelligent accent spring testing table adopts syllogic weighting platform structure, comprise: leading portion Weighing mechanism, back segment Weighing mechanism, the accent spring main body mechanism of weighing, the motor train unit vehicle is parked in successively to weigh and transfers on the spring main body mechanism, and the accent spring amount that each transfers the spring position is measured and calculated automatically to vehicle automatically.
Described leading portion Weighing mechanism is made up of track, support, LOAD CELLS.Described track is I shape standard rail, and support is welded by steel plate.Described support connects LOAD CELLS, the LOAD CELLS supporting track, and vehicle acts on the LOAD CELLS fully by track.
Described back segment Weighing mechanism is made up of track, support, LOAD CELLS.Described track is I shape standard rail, and support is welded by steel plate.Described support connects LOAD CELLS, the LOAD CELLS supporting track, and vehicle acts on the LOAD CELLS fully by track.
Described back segment Weighing mechanism and leading portion Weighing mechanism are similar.
Described weighing transfers the spring main body mechanism to be made up of two groups of accent spring mechanisms of weighing, and respectively two bogies of motor-car vehicle measured.Described accent spring Weighing mechanism is made up of track, support, adjusting mechanism, LOAD CELLS, displacement transducer and base.Described track is I shape standard rail, and support is welded by steel plate.Described adjusting mechanism is connected with LOAD CELLS, can adjust the height of LOAD CELLS, and the height control position is determined by described displacement transducer.Described LOAD CELLS is for satisfying the standard transducer of the range of weighing.Described displacement transducer is the standard transducer that resolution is not less than 0.01mm.Described base is welded by steel plate, and support, adjusting mechanism all are connected with base.
The utility model compared with prior art by adjusting the height of measured wheel of vehicle, is accurately measured the wheel load of each bogie, eliminates the front and back vehicle to the influence of tested vehicle, and then accurately calculates accent spring amount, accomplishes intelligence accent spring.The present invention shortens the time of transferring the spring operation greatly, reduces adjustment personnel's working strength.
