In order to test different classes of on a locomotive bed and locomotive different model, the position of testing table rail wheel must be adjusted fast, easily, and rail wheel is aimed at mutually with locomotive wheel.Each rail wheel is installed on separately the base.Present testing table is made up of standard gauge and floating point rail device, locomotive for the single model of test is not only convenient and practical but also safe and reliable, but test then because the position of floating point rail must change with the wheelbase of locomotive wheel for various engines, this just needs to adjust the position of rail wheel and floating point rail, this is an effort time-consuming job, and because the locomotive wheel position of different model locomotive is different, so can not equivalently move between the rail wheel, otherwise do not reach the requirement that wheelbase is regulated.
Summary of the invention:
Goal of the invention of the present utility model is to disclose a kind of regulating device that can move locomotive bed track crop rotation diverse location.
Realize that technical solution of the present utility model is as follows: motorized speed reducer connects bevel gear housing, bevel gear housing connects a leading screw, and all vertically be arranged on the centre position or the both sides of rail wheel, the base of each rail wheel is provided with two plate washers at regular intervals, leading screw passes plate washer, and the leading screw between two plate washers is provided with a nut; When leading screw rotated, nut can not rotate because of blocking, and can only move axially along leading screw, and then nut promotes plate washer and then promotes the displacement of rail wheel base by displacement, and rail wheel just can be realized the adjusting of wheelbase.
The utility model is simple in structure, is convenient to operation, good reliability, the plate washer on the different track wheel seats and the different spacing of nut, can make the adjusting displacement difference of each rail wheel, then can realize the adjusting of different rail wheels, make locomotive bed can adapt to the test of the locomotive of dissimilar and different model.

Fig. 2 is the schematic side view of Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment.
Fig. 4 is the structural representation of another embodiment of the utility model.
Fig. 5 is the synoptic diagram of rail wheel regulated quantity.
Embodiment:
See also Fig. 1~Fig. 5, specific embodiment of the utility model is as follows: motorized speed reducer 1 connects bevel gear housing 2, bevel gear housing 2 connects a leading screw 3, motorized speed reducer 1 drives bevel gear housing 2 and then drives leading screw 3 and rotates, above-mentioned speed reduction unit 1, bevel gear housing 2 and leading screw 3 can vertically be arranged on the centre position of rail wheel 4, and the base 5 of each rail wheel 4 is provided with two plate washers 6 at regular intervals, and the leading screw 3 that leading screw 3 passes between plate washer 6, two plate washers 6 is provided with a nut 7; When motorized speed reducer 1 drove leading screw 3 rotations, nut 7 can be stuck in base 5 surfaces and can not rotate, and can only move axially along leading screw 3, and then nut 7 displacements promote 5 displacements of rail wheel base, the rail wheel 4 corresponding adjustings that just can realize wheelbase.
Another embodiment of the present utility model is: motorized speed reducer 1, bevel gear housing 2 and leading screw 3 vertically are arranged on a side of rail wheel base 5, opposite side at rail wheel 5 is arranged with bevel gear housing 2 and leading screw 3, be connected with a coupling shaft 8 between two bevel gear housinges 2, establish two plate washers 6 at regular intervals at the sidewall of each rail wheel base 5, the leading screw 3 that leading screw 3 passes between plate washer 6, two plate washers 6 is provided with a nut 7; 1 of motorized speed reducer can drive two bevel gear housinges 2 simultaneously, 5 displacements of final drive track wheel base, owing to be the both sides application of force of each rail wheel base 5, then the collimation of displacement improves, and further improves the precision of regulating.
Above-mentioned plate washer 6 is welded on the base 5, plate washer 6 and together displacement of base 5.
Because locomotive wheel 10 positions of different locomotives are different, so three pairs of rail wheels 4 (both rail wheel a, b, c) can not equivalently move, otherwise do not reach the requirement that wheelbase is regulated, for example desire is adjusted to the position of locomotive II with rail wheel from locomotive I, and the displacement of rail wheel a, b, c should be respectively C, D or E (Fig. 5).That is to say that when rail wheel c moved E, rail wheel b can not move in the E-D scope, actual displacement is D.Rail wheel a can not move in the E-C scope, and actual displacement is C.
Realize this requirement, need between the plate washer of different rail wheel bases and nut, be provided with different gaps.What move at the interstice coverage inner nut is idle motion, does not promptly recline between nut and the plate washer, and nut can not promote rail wheel and move.Only cover idle motion, after nut and plate washer recline, just produce the effect that promotes rail wheel.
