Abstract
The utility model discloses an infrared detecting point aligner used for detecting the temperature of axle shafts of guest and goods vehicles on railways. The utility model comprises a casing, an electronic device and a circuit device. The utility model is characterized in that the inner part of the casing is provided with a battery pack, a charging circuit, a free-running multivibrator used for generating simulating heat source signals, and a level driving proof reading display circuit used for detecting the precision of the infrared point. Because a miniature lamp is used as the simulating heat source, the utility model has the advantages of small point area, stable frequency, rapidity and accuracy for finding the point and no influence of weather.
Description
The utility model relates to the measurement of temperature, is that a kind of infrared ray searchlighting point prover and infrared ray searchlighting device cooperate, and is used for the temperature of detecting railway waggon axle.
Operating temperature for detecting railway visitor, goods waggon axle, at each emphasis traffic coverage, surveying really at railway two, the allocation place is provided with the infra-red detection device, the critical component of this device is an infrared probe, this probe should be radiated on the assigned position of operational vehicle axle all the time, and irradiated area is generally 4 sq cms.Owing to the worker is engaged in overhauling, the climate change reason, often cause rail change up and down to take place with respect to the ground level at detector place, thereby change up and down takes place in the waggon axle that causes operating on the rail, that is to say that waggon axle is in upset condition with respect to the shadow surface (point) of infrared probe, therefore, should proofread (twice of every day) the shadow surface of infrared probe, make shadow surface all the time on definite zone of waggon axle.Check and correction way before the utility model occurs is: adopt mosquito-repellent incense or fire of cigarette tip simulation thermal source signal to proofread.Concrete grammar is that hand-held mosquito-repellent incense of staff or fire of cigarette tip swing back and forth near testing jig regulation point (being equivalent to the waggon axle end face), judges that by the test value of milivoltmeter whether probe is radiated on definite zone of axle, judges promptly whether sensing point is accurate.This manual swing mode by rule of thumb, the fiery ash of its hunting frequency shakiness, amplitude shakiness, mosquito-repellent incense or cigarette end head causes the temperature shakiness of thermal source.Manual swing mode also is subjected to weather effect, the normal check and correction of influence in various degree of raining or blow all.
