Abstract
The invention discloses a kind of methods of mobile rim and spoke ultrasonic fault detection system roller devices automatic centering, specifically includes the following steps: (1) installs two laser sensors on the car body of fault detection system；(2) fault detection system is when train wheel blocks sensor 1 in lifting process, and trigger sensor 1, then system stops rising, and system car body is mobile to 2 direction of sensor, until trigger sensor 2；(3) fault detection system wheel in uphill process blocks the then system stopping rising of 2 trigger sensor 2 of sensor, and system car body is to sensor 1 to movement, until trigger sensor 1；(4) when sensor 1,2 triggers simultaneously, system lifting continues until triggering limit sensors lifting limit, lifting movement terminate；(5) idler wheel 1 after lifting movement on fault detection system, idler wheel 2 are drawn close and are come into full contact with wheel rim, carry out wheel actions, centering terminates；This method of the present invention is simple and easy, can automatically control car body centering.
Description
Technical field
The present invention relates to a kind of car body centering method methods, and in particular to a kind of movable type rim and spoke ultrasonic examination system
The method of system roller devices automatic centering.
Background technique
Mobile rim and spoke fault detection system detects a flaw to rim and spoke for motor train unit train wheel.When flaw detection operation, need
Jacking apparatus jacks wheel to from track bridge, so that roller devices and wheel come into full contact with wheel rim, then starting jacking makes wheel pair
Tyre tread is separated with track.After tyre tread is separated with track, start roller devices, the contact friction force by roller devices and wheel rim makes
It must take turns to the 360 ° of detections for completing ultrasonic fault detection system to wheel to rim and spoke that rotate a circle.
When jacking, the wheel center of circle must be made to be located at the center of two wheel rims of roller devices set, if the wheel center of circle is deviateed, rolling
Turn is set wheel rim set and is contacted with wheel rim, when rolling, be easy to cause wheel to skidding is rolled, beats.Wheel is easy to when skidding
Cause missing inspection.Wheel be easy to cause defective coupling to bounce, causes testing result unstable.So idler wheel must be made to fill when operation
Centering is set, is made by way of manually adjusting mobile system car body visual observations with mobile rim and spoke fault detection system at present
Roller devices centering is obtained, it is larger that this mode operates the lower and error of centralization.
Summary of the invention
The technical problem to be solved by the present invention is to the shortcomings that overcoming the prior art, provides a kind of mobile rim and spoke
The method of ultrasonic fault detection system roller devices automatic centering, this method is simple and easy, can automatically control car body centering.
In order to solve the above technical problems, the present invention provides a kind of mobile rim and spoke ultrasonic fault detection system idler wheel dress
The method for setting automatic centering, specifically includes the following steps:
(1) two laser sensors are installed on the car body of fault detection system；
(2) fault detection system is when train wheel blocks sensor 1 in lifting process, and trigger sensor 1, then system stops rising,
System car body is mobile to 2 direction of sensor, until trigger sensor 2；
(3) fault detection system wheel in uphill process blocks the then system stopping rising of 2 trigger sensor 2 of sensor, system car body
To sensor 1 to movement, until trigger sensor 1；
(4) when sensor 1,2 triggers simultaneously, system lifting continues until triggering limit sensors lifting limit, lifting movement knot
Beam；
(5) idler wheel 1 after lifting movement on fault detection system, idler wheel 2 are drawn close and are come into full contact with wheel rim, and it is dynamic to carry out idler wheel
Make, centering terminates.
The beneficial effects of the present invention are:
Compared at present with mobile rim and spoke fault detection system by manually adjusting the sides of mobile system car body visual observations
Formula makes roller devices centering, and this mode operates that the lower and error of centralization is larger, operates letter using centering method of the invention
Single easy, error is small, and accuracy is high.
Detailed description of the invention
Fig. 1 is the action flow chart of the embodiment of the present invention；
Fig. 2 is the structural schematic diagram of the embodiment of the present invention.
Specific embodiment
Embodiment 1
A kind of method such as Fig. 1 of mobile rim and spoke ultrasonic fault detection system roller devices automatic centering provided in this embodiment
And shown in 2, specifically includes the following steps:
(1) two laser sensors are installed on the car body of fault detection system；
(2) fault detection system is when train wheel blocks sensor 1 in lifting process, and trigger sensor 1, then system stops rising,
System car body is mobile to 2 direction of sensor, until trigger sensor 2；
(3) fault detection system wheel in uphill process blocks the then system stopping rising of 2 trigger sensor 2 of sensor, system car body
To sensor 1 to movement, until trigger sensor 1；
(4) when sensor 1,2 triggers simultaneously, system lifting continues until triggering limit sensors lifting limit, lifting movement knot
Beam；
(5) idler wheel 1 after lifting movement on fault detection system, idler wheel 2 are drawn close and are come into full contact with wheel rim, and it is dynamic to carry out idler wheel
Make, centering terminates.
Using centering method of the invention, operation is simple, and error is small, and accuracy is high, high degree of automation, reduces labor
Fatigue resistance, save the cost.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
