The utility model resolves the major defect that the vehicle needs to get on the main line to test operation after repairing, the utility model can simulate the operation of the vehicle at various speeds and test various parameters, thus avoiding the disturbance of the normal order of railyway transportation, which is caused by the operation of the vehicle on the main line, and saving a lot of expenses of the operation test of the vehicle.
Description
The utility model relates to a kind of pick-up unit of railway locomotive, particularly a kind of device that the locomotive car load is carried out running test.
Regulation according to Ministry of Railways's locomotive inspection and repair rules: " in repair locomotive and should carry out the main track test run that one way is no less than 50Km; " but, because China railways main track train is intensive at present, transportation is busy, the normal order of transportation by railroad is seriously disturbed in the locomotive test run, and locomotive test run expense is huge, so the main track test run difficulty behind the locomotive inspection and repair is increasing.
Goal of the invention of the present utility model is to disclose a kind of test unit that need not just can carry out omnidistance operation in the main track operation to the locomotive after the maintenance.
Realize that technical solution of the present utility model is as follows: at the output of the rotating rail wheel dynamometer motor that is coupling, dynamometer motor connects the excitation unit of scalable dynamometer motor power, and rail wheel is between the floating point rail device of position of being convenient to leave office on the tested locomotive.Design concept of the present utility model is as follows, and in normal main track process of the test, the wheel speed of locomotive is consistent.At this is to replace railway track with rail wheel, each driving wheel of supporting locomotive, the number that track changes equates with the number of locomotive driving wheel, when the driving wheel of locomotive rotates, the drive track relatively rotates, and the traction power of output locomotive, the test method of this engine static-state, can simulate the operating condition of locomotive on main track fully, and carry out the detection and the fault diagnosis of various operational factors, because the feature difference of dynamometer motor is different with the resistance of kinematic train, the rotating speed that each track changes is difficult to automatically synchronously, by the adjusting on the excitation unit, promptly the rotating speed by detecting each dynamometer motor and comparing changes the field voltage of each dynamometer motor then, each rail wheel is turned round with synchronous rotational speed, and can enlarge the variation range of simulation locomotive running speed, thereby record the pulling figure of locomotive by changing the field voltage of dynamometer motor.
The utility model has solved the locomotive after the maintenance need go up the significant deficiency that main track carries out test run.On the utility model, just can simulate the operation of the various speed of a motor vehicle of locomotive, and various parameters are detected, avoid the interference of locomotive main track operation, save the expense of locomotive test run in a large number the normal order of transportation by railroad.

Embodiment of the present utility model can be referring to Fig. 1--and-Fig. 5 provides the preferred plan of embodiment and further perfect scheme, the structure of present embodiment is as follows: at the output of rotating rail wheel 1 dynamometer motor 6 that is coupling, dynamometer motor 6 connects the excitation unit of scalable dynamometer motor 6 power, and rail wheel 1 is between the floating point rail device of being convenient to leave from office position on the tested locomotive.Detected locomotive at first enters the platform position by the floating point rail device, see also Fig. 3, the structure of above-mentioned floating point rail device is: floating point rail 8 is installed in the both sides of rail wheel 1, the one end joins with normal track, the other end is and the identical cambered surface of rail wheel 1 radius, one down suction 14 is arranged between the rail point of rail wheel 1 and floating point rail 8, floating point rail 8 is fixedlyed connected with base plate 9, and be assemblied on the bearing 11 by fastener 10, pilot pin 12 and pressure spring 13 are housed between base plate 9 and bearing 11, between fastener 10 and the base plate 9 the gap (see figure 4) that equates with gap 14 is arranged, when the driving wheel of locomotive is rolled on the floating point rail 8, spring 13 is compressed, tongue 8 and base plate 9 sinkings one intersegmental crack, base plate 9 contacts with bearing 11, the wheel face of the tip of floating point rail 8 and rail wheel 1 is fitted simultaneously, floating point rail 8 and rail top face form the track of a basic horizontal, guarantee that locomotive passes through smoothly, when locomotive driving arrives the summit of rail wheel 1, the locomotive driving wheel breaks away from floating rail point 8, floating point rail 8 moves above-mentioned down suction 14 under the effect of spring 13, the wheel face of the tip of tongue 8 and rail wheel 1 disengages, and rail wheel 1 freely rotates when guaranteeing locomotive test.For guaranteeing the suitable use of floating point rail device, down suction 14 the bests between the above-mentioned rail wheel 1 and the rail point of floating point rail 8 are about 5mm, it had both guaranteed between rail wheel 1 and the tongue 8 that one had reliable disengaging distance, need not excessive deformation distance be arranged spring 13 again, to help guaranteeing serviceable life of the present utility model.Adopt above-mentioned floating point rail device can realize the locomotive position of go up leaving office voluntarily, simple in structure to guarantee, the characteristics of reliable effect, than the method for designing safe ready that locomotive integral body is hung on the platform position.The utility model is to replace railway track with rail wheel 1, and each driving wheel of supporting locomotive, the number of rail wheel equate with the number of locomotive driving wheel, when the driving wheel of locomotive rotates, drive rail wheel 1 and relatively rotate, and the traction power of output locomotive.In order to prevent the vertical position of locomotive, when the locomotive driving wheel is positioned at the summit of rail wheel 1, an end of bearing 11 be provided with one fixedly hitch 2 locomotive is locked (see figure 1), also can be respectively equipped with fixedly hitch 2 at the two ends of bearing 11, with more reliable fixedly locomotive, the position just of the present utility model of the bearing 11 here, at first be that the locomotive driving wheel rotates and drive track wheel 1 rotates during test, drive dynamometer motor 6 work, because the property difference of dynamometer motor 6 is different with the resistance of kinematic train, the rotating speed of each rail wheel 1 is difficult to automatically synchronously, for making locomotive identical with ruuning situation on the railway at the state on the test unit, the rotating speed of rail wheel 1 should equate, just can make the rotating speed unanimity of the driving wheel of locomotive, dynamometer motor 6 connects the excitation unit of the power of adjustable
