Description
Technical field
The utility model relates to track traffic security fields, specifically refers to a kind of track switch vibration monitoring device.
Background technology
Train at a high speed by time track switch (especially tongue) bear great low frequency large amplitude and high frequency small amplitude motion power (vibration acceleration), as fail effective vibration damping, goat and track switch all will be injured, its utilization state will worsen rapidly.Goat is more responsive to vibration acceleration, too high vibration acceleration, can accelerate goat internal part wearing and tearing, reduce goat serviceable life, also can cause movable part to get loose.If track switch part stock rail, tongue, movable point frogs bear too high vibration acceleration for a long time, may cause the serious track switch problems such as rail fracture, threaten traffic safety.Track switch part vibration acceleration is too high, and reason may have: when the opening of a point causes car, wheel rim strengthened the impact of tongue, stock rail, and it is large that the acceleration bearing becomes; Heart rail is not closely connected while causing car, and wheel rim strengthens the impact of heart rail, wing rail, and it is large that the acceleration bearing becomes; Height is creeped, lifted up to tongue; Track switch geometrical variations, moving bar piece become flexible.
The acceleration that track switch stock rail part is born can be delivered to goat by actuating strut, indication rod.The acceleration that monitoring analysis goat bears, vibration frequency, Oscillation Amplitude can concentrated expression track switch integral body use quality, find in time the hidden danger that track switch exists.
In acceleration measurement method, the method that can be used for vibration acceleration measurement mainly contains magnetoelectric sensor, piezoelectric acceleration transducer at present.Magnetoelectric sensor is to utilize coil in permanent-magnetic field, to make relative motion cutting magnetic line to produce the voltage signal being directly proportional to vibration velocity.Through amplifying, infinitesimal analysis can computing be surveyed vibration velocity, displacement and acceleration.Magnetoelectric sensor is highly sensitive, internal resistance is low.In mechanical vibration test, be widely used.Piezoelectric acceleration transducer claims again piezoelectric accelerometer.It also belongs to inertial sensor.General acceleration transducer is exactly this characteristic of crystal modification causing due to acceleration of having utilized its inside.Because this distortion can produce voltage, as long as calculate the relation between the acceleration that produces voltage and apply, just can change into Voltage-output by degree of will speed up.Due to the architectural characteristic of piezoelectric acceleration transducer, so piezoelectric acceleration transducer fatigue resistance is good, reliability is high, the life-span is long.
At present scene has two kinds of modes to obtain track switch vibration data: 1. manual detection method: by portable instrument as detecting main frame, adopt magnet steel base that piezoelectric acceleration transducer is adsorbed in to measuring position, before crossing car, main frame is opened, excessively after car, read the vibration data after collection.The method is applicable to the lower shipping circuit of speed.After train speed raising, because train Negotiation speed is fast, now do not allow upper track operation, cannot carry out the collection of this vibration data and obtain.2. the inner built-in acceleration transducer detection method of the monitoring equipment in goat: by the inner built-in acceleration transducer of inner other monitoring equipment arranging of goat, carry out acceleration information collection.The remarkable shortcoming of the method is: be arranged on the sensor of monitoring equipment inside in goat, what it can reflect can only be the suffered Vibration Condition of monitoring equipment, can not reflect track switch, the suffered impact condition of goat.
