Description
Technical field
The utility model is related to a kind of locomotive technology, especially a kind of locomotive thermometry is specifically a kind of online
Train Wheel temperature detection device of the detection wheel to temperature.
Background technology
Passenger train is assembled with axle temperature annunciator at present, can in real time be monitored to axle temperature, when bearing in the event of failure
It alarms.But the functional defect of axle temperature annunciator, which is embodied in it, can only measure axle temperature, be unable to measurement wheel temperature.According to statistics, train
Band-type brake accident monthly has generation, seriously affects railway operation safety.
When band-type brake accident occurs for train, wheel will necessarily be abnormal variation to temperature.Train band-type brake accident is totally divided into two
Kind, one is brake apparatus mechanical breakdowns to make the brake force of certain wheel pair inadequate, and other wheels can be less than to temperature by being embodied in the wheel
To temperature;Another kind is that Brake pipe pressure is insufficient or brake apparatus mechanical breakdown makes band-type brake be in on-position always, with wheel
To keeping rubbing for a long time so that wheel drastically increases temperature, and band-type brake can make wheel strength between locking, with rail under extreme case
Friction threatens railway operation safety.
System-wide braking brake failure is inertial defect at present, lacks effective prevention and judging means in advance.Part 25T and
Although 25G vehicles have installed braking on-Line Monitor Device additional and have been monitored to train air brake portion, basis is made
The monitoring of dynamic part is not also comprehensive.By the study found that band-type brake vehicle wheel has not the more other normal vehicle temperature of portion temperature
With the raising of degree.For this reason, it may be necessary to extend axle temperature detectors, increases wheel temperature monitoring channel and be used to supervise temperature on wheel
It surveys, the judgement to band-type brake failure and forecast is realized by monitoring wheel to the variation of temperature.
Since train wheel is kept in motion at runtime, so contact type measurement can not be carried out.It is most reliable at present
Non-contact measurement is infrared thermometry.Infrared temperature sensor is widely used in ground monitoring system, is passed through in train
Pass through infrared sensor thermometric when monitoring point.Infrared sensor is not yet present in vehicular applications, is because of infrared sensor pair
Water proof and dust proof is more demanding, and bad environments when train operation, and Sand Dust Environment can be that infrared sensor measurement brings challenges.It needs
Dust cover of the research and development suitable for infrared wheel temperature sensor effectively excludes influence of the sand and dust to infrared temperature probe, realizes infrared wheel
Temperature sensor it is non-maintaining.
Utility model content
The purpose of this utility model, which is existing vehicle-mounted axle temperature system, detection wheel cannot accomplish temperature change in real time
To the on-line real-time measuremen of band-type brake wheel pair, there are problems that operational safety hidden danger, designs a kind of energy on-line real-time measuremen locomotive wheel
To the detection device of temperature, lay the foundation for Railway wheelset band-type brake on-line early warning.
The technical solution of the utility model is:
A kind of Train Wheel temperature detection device, it is characterized in that it includes infrared sensor 1, infrared sensor 1 is mounted on angle steel
On holder 2, angle bar frame 2 is fixed on underbody crossbeam 3, and infrared sensor face wheel is to one end upper cover of brake disk 4 equipped with dust-proof
Cover 5.
The infrared sensor 1 is mounted on the cantilever end of angle bar frame 2, and the other end of angle bar frame 2 passes through bolt
It is fixedly linked with underbody crossbeam 3.
The probe of the infrared sensor 1 is from wheel to being 200 ± 5 millimeters with a distance from 4 peak of brake disk.
The infrared sensor 1 is powered by power module 6, its signal output end is connected with processor 7, and processor is logical
Communication module 8 is crossed to be communicated with Upper system 9.
Dust removal heater is added in the dust cover, is used to form draught head, prevents dust from entering.
The beneficial effects of the utility model:
The utility model solves the installation of infrared sensor and dust-proof problem, realizes on-line checking of the wheel to temperature,
Foundation is provided for anti-band-type brake on-line early warning.
The utility model is simple in structure, easy to install and use.
