The tester is also provided with an uninterrupted power supply device. The utility model can make use of a computer to control, detect, automatically record and count the first data of the continuous temperature change of the rail and the air. The utility model has the advantages of simple structure, low cost, convenient operation and use and high accuracy.
Description
The utility model relates to railway rail temperature, temperature field tests.
Because the geographical conditions difference, along with weather, variation of temperature, rail produces different internal stresss.Under the temperature stress effect, three foldings and expansion rail track accident constantly take place, and directly jeopardize safety of railway traffic especially.Thereby pass through the continuous temperature that changes and disclose the constantly inner link and the rule of the rail temperature of variation, manage significant for track quality.Design and laying to gapless track has important use value especially.The rule that the rail temperature changes is the basis that circuit is big or middle, maintenance is very important.According to " railway line maintenance rule " the 3rd, 4,5 regulation, it is directly related with the local maximum rail temperature difference and construction rail temperature at that time to give the calculating of staying rail gap.At present, China to adopt empirical data be that the highest rail temperature in locality equals the local highest temperature and adds 20 ℃.Yet differ in highest temperature various places, all with this add 20 ℃ just unreasonable.Thereby we should realize obtaining as early as possible being fit to the continuous data of each department rail, temperature Change, and present this data is in no position to take possession of.
The purpose of this utility model is to release a kind of appliance computer control detection, the rail that writes down and add up automatically, air continuous temperature measurement device.Obtain to be fit to the each department rail wet temperature continually varying firsthand information as early as possible to satisfy.
The technical solution of the utility model is: a kind of rail wet temperature intelligent tester is made up of temperature probe, detecting device, analog to digital converter and main frame.Its special character is that temperature probe is a platinum resistance; Detecting device is made up of detection electric bridge, multipath conversion control circuit; Analog to digital converter is made up of the A/D change-over circuit; Main frame is made up of TP-801 single card microcomputer, mini-printer, power circuit, power control circuit, external tapping and display circuit.
The utility model is described in further detail below in conjunction with embodiment:
