Description

A kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail
Technical field
The utility model belongs to railway transportation equipment technical field, and more particularly to a kind of rail that is used for hands over car wheel-set non-pulling wheel The bearing testers that Xuan is repaiied.
Background technology
Wheel directly contacts the vehicle of track traffic with rail in operation, effect of the wheel in load pressure and frictional force It is lower that serious abrasion can occur, the index severe overweight such as out-of-roundness, surface flatness, roughness of wheel is caused, influences vehicle Safe operation, therefore inspection and repair system provides, vehicle runs and wheel is carried out into turning after certain mileage, recovers the precision of wheel Index, to ensure the safe operation of vehicle.
Axle box bearing is a critical component of vehicle safety operation, by can only lean on temperature index in vehicle operation Judge the state of bearing, and judgement of the temperature index to the initial failure of bearing is helpless, temperature is once exceeded, then marks Will that bearing fault is very serious, may threaten the safe operation of vehicle at any time.If the turning cycle of wheel can be coordinated, Judge can be monitored to the state of axle box bearing, then can greatly improve the safety of vehicle operation while turning wheel Property.
Utility model content
The utility model provides a kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail, to in-orbit friendship The problem of detecting during car wheel-set non-pulling wheel Xuan is repaiied while to wheel set bearing state, to improve the safety of vehicle operation Property.
A kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail, the detector include data acquisition unit, work All-in-one, and first, second, third and fourth vibrating sensor are controlled,
First, second, third and fourth vibrating sensor accesses data acquisition unit, and data acquisition unit is connected by communication serial port To industrial computer, by the data transfer collected to industrial computer,
The display of industrial control all-in-one machine, for the figure shows of testing result,
First, second vibrating sensor access rail hands over the first round pair of the bogie of car,
Third and fourth vibrating sensor access rail hands over the second wheel pair of the bogie of car.
The first, second, third and fourth vibrating sensor is separately mounted to Xuan and repaiies biography in the middle part of the upper paw of lathe In sensor mounting groove, and fixed with M6 bolts, the cable of vibrating sensor, which is arranged in the wire casing of sensor, to be fixed.
Detector also includes the first speed probe and the second speed probe access data acquisition circuit, for detection wheel To rotating speed.
Vibrating sensor uses piezoelectric acceleration transducer.
The utility model is mounted in the vehicle bearing monitoring instrument on underfloor wheel lathe, can be in the turning process of wheel Monitoring and judge of the middle realization to axle box bearing running status, to improve the security of vehicle operation.
Brief description of the drawings
Detailed description below is read by reference to accompanying drawing, the utility model illustrative embodiments above-mentioned and other Objects, features and advantages will become prone to understand.In the accompanying drawings, show that this practicality is new by way of example, and not by way of limitation Some embodiments of type, wherein:
Fig. 1 is the circuit block diagram of the utility model bearing testers.
Embodiment
As shown in figure 1, a kind of bearing testers for handing over car wheel-set non-pulling wheel Xuan to repair for rail, the detector include data Acquisition Circuit, industrial control all-in-one machine, and first, second, third and fourth vibrating sensor.First, second, third and fourth is shaken Dynamic sensor access data acquisition circuit, data acquisition unit are connected to industrial computer by communication serial port, the data transfer that will be collected To industrial computer.
The display of industrial control all-in-one machine, the figure shows for testing result.First, second vibrating sensor access rail is handed over The first round pair of the bogie of car, the third and fourth vibrating sensor access rail hand over the second wheel pair of the bogie of car.
The first, second, third and fourth vibrating sensor installs Xuan and repaiies sensor on lathe in the middle part of paw respectively In mounting groove, and fixed with M6 bolts, the cable of vibrating sensor, which is arranged in the wire casing of sensor, to be fixed.
Detector also includes the first speed probe and the second speed probe access data acquisition circuit, for detection wheel To rotating speed.
In use, detector of the present utility model can be 1 or two rotating speed inputs, can also be inputted without rotating speed.Can To be two passages or four-way, four-way collecting unit, making for independent single channel and two-way or four road signals measurement simultaneously can be applicable Use situation.Communicated between Acquisition Circuit and industrial computer using RS232.Industrial control all-in-one machine with touch-screen, is installed on operator side The position of convenient to operate.
In Xuan repaiies work, paw is compressed axle box by operator, without additionally being adjusted to vibrating sensor, bearing Vibration signal is delivered to vibrating sensor by axle box, paw.Detector detects the vibration data of bearing, self-excited oscillation in future sensing The vibration signal of collection is demodulated and wrapped with FFT processing into data signal, data acquisition unit by the analog-signal transitions of device Network total value and envelope frequency spectrum, the alarm limits according to setting judge the degree of injury of bearing, and according to the bearing designation monitored It is corresponding to arrive component feature value, provide the damage report of specific part.
What deserves to be explained is created although foregoing teachings describe the utility model by reference to some embodiments Spirit and principle, it should be appreciated that, the utility model is not limited to disclosed embodiment, and each side is drawn Divide and also do not mean that the feature in these aspects can not combine, this division is merely to the convenience of statement.The utility model purport Covering various modifications included in spirit and scope of the appended claims and equivalent arrangements.
