Baffle plate prevent the further transverse shifting of car body, finally in the presence of frictional force, rail-defect detector car stops, it is therefore prevented that
Rail-defect detector car is toppled, it is to avoid the generation of accident, and the structure of the baffle plate is most simplified, and at utmost mitigates vehicle weight
Amount.
Brief description of the drawings
Fig. 1 is facing for the wheel shaft structure of the electric rail-defect detecting car under the normal enforcement state of the utility model embodiment
Figure；
Fig. 2 is the front view of the wheel shaft structure of the electric rail-defect detecting car under the derailing state of the utility model embodiment.
Embodiment
Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before
Put and implemented, give detailed embodiment and specific operating process, but protection domain of the present utility model is not limited
In following embodiments.
Refer to shown in Fig. 1, the Overthrow preventing device on the steel rail ultrasonic flaw detecting car of the present embodiment includes bridge axle 1, installed
In the road wheel 2 of the rail-defect detector car at the two ends of bridge axle 1, and it is separately mounted to the retaining device 3 of both sides road wheel 2.
The retaining device 3 can be the pivotable outside for being fixed on road wheel 2, and such as retaining device 3 is solid by bearing
The end of bridge axle 1 is scheduled on, retaining device 3 can be rotated around bridge axle 1.
Or the retaining device 3 can also be directly anchored to the outside of road wheel 2, the diameter of such as retaining device 3 is smaller
One end be fixed on the end of bridge axle 1, or less one end of diameter of retaining device 3 is fixed on road wheel 2.
Specifically, the retaining device 3 includes the baffle plate 32 and the installation axle fixed with the inner side of baffle plate 32 positioned at outside
34, the diameter of baffle plate 32 is more than the diameter of installation axle 34, and the periphery of baffle plate 32 is higher by the outer surface of installation axle 34, baffle plate
32 is overall rounded.The lateral surface of road wheel 2 is more than the width of the upper part of rail 4 apart from the distance between medial surface of baffle plate 32
Degree.
It is preferred that, baffle plate 32 can be coaxial or not coaxial with installation axle 34.
It is preferred that, baffle plate 32 welds together with installation axle 34, or baffle plate 32 is integrally formed with installation axle 34.
When retaining device 3 can be it is pivotable be fixed on road wheel 2 outside when, installation axle 34 is fixed on by bearing
The end of bridge axle 1, retaining device 3 can be rotated around bridge axle 1.
When retaining device 3 can be integrally fixed at the outside of road wheel 2, installation axle 34 is fixed on the end of bridge axle 1, or
It is fixed on road wheel 2.
When rail-defect detector car is normally run, two road wheels 2 are rotated on the rail 4 of respective side respectively, when due to accident
When situation rail-defect detector car derails, as shown in Fig. 2 due to the effect of inertia, rail-defect detector car can be tilted towards horizontal side, this
When, the retaining device 3 of the reverse side of road wheel 2 of incline direction is fallen on rail 4, because retaining device 3 has the He of baffle plate 32
Installation axle 34, installation axle 34 is against the upper surface of rail 4, and baffle plate 32 is stuck in the lateral surface of rail 4, prevents rail-defect detector car
Further tilt, and because the road wheel 2 of both sides is departing from track, in the presence of frictional resistance, rail-defect detector car is most
It can stop eventually, it is therefore prevented that the generation toppled.
The retaining device 3 uses simple baffle plate 32 and the structure of installation axle 34, farthest alleviates complete vehicle weight, and
And prevent toppling for rail-defect detector car, it is to avoid the generation of accident.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
