Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of railcar complete vehicle test platform,
Can carry out the hauling ability test to railcar, can realize that railcar does not go up circuit, carry out the hauling ability test, promptly needn't take railway track, transportation by railroad without any influence, has been saved a large amount of testing expenses again at stand.
The technical solution of the utility model is: railcar complete vehicle test platform, it is right by rail track, guide beam, upper bracket, support wheel, base, transmission shaft, universal joint, power-measuring system, electric control gear, draw beam, tractive force measurement mechanism, hydraulic jack, parallels, bearing spider, rail rest are formed, on the pedestal on buried concrete ground, be fixed with two bases, the two ends of each base are fixed with bearing spider, it is right that bearing spider connects the left and right sides support wheel of tape spool respectively, and left and right sides support wheel is to the wheel of the tested railcar of top connection.Each fixes two hydraulic jacks about on the base of the right inboard of left and right sides support wheel, is connected with guide beam by parallels, upper bracket above the hydraulic jack, and guide beam is connected with the rail track by rail rest.The support wheel of left side tape spool is to being connected with power-measuring system by universal joint, transmission shaft.Be fixed with the tractive force measurement mechanism on the mattess on the ground and be connected with hitch on the tested railcar by draw beam.Power-measuring system and tractive force measurement mechanism are electrically connected with the electric control gear of fixing on the ground.
The beneficial effects of the utility model are: the power of tested railcar can be delivered to power-measuring system by the right friction of wheel and support wheel and by transmission shaft, universal joint, be converted into electric energy and regulate and consume through the wasted work system, can describe the pulling figure of railcar accurately, can also directly measure draw bar pull by draw beam and tractive force measuring system, on the railcar testing table, railcar is tested, can not take railway track, avoid train operation is brought influence, can save a large amount of testing expenses simultaneously.
