Multipurpose calibrator for infrared journal temperature detector

Abstract

The invention discloses a multipurpose scaler of infrared axle temperature detecting equipment, which consists of axial plane support rack and vertical support rod on the support rack, wherein the support rack is integrated of horizontal insulating rod, axial plane location sleeve, tensioning location seat, horizontal adjustment seat and vertical adjustment seat; the location head of tensioning location seat is tensioned under the base plane of rail lateral face; the vertical support rod is fixed in the vertical adjustment seat of horizontal adjustment rod with prismatic cross-section; the heating blackboard or analog orientation board is fixed on the vertical support rod as the standard heater of analog axle box; the laser prover is placed on the infrared probe in the box of infrared axle temperature detecting equipment. The invention is compatible with infrared axle temperature detecting equipment of each type bus and truck, which marks the temperature and location simultaneously as well as improves the detecting precision greatly.

Description

technical field [0001] The invention relates to a detection and calibration device for infrared shaft temperature detection equipment used to monitor and ensure the safety of railway passenger and freight vehicles, especially a detection of the temperature measurement accuracy and probe azimuth angle of such infrared shaft temperature detection equipment And adjust the calibration multi-purpose calibration instrument. Background technique [0002] At present, monitoring the change of bearing temperature during the operation of railway passenger and freight vehicles is the key link to prevent passenger and freight vehicles from burning and cutting shafts, and the infrared shaft temperature detection equipment installed at a specified distance on both sides of the railway trunk line is the Special equipment for monitoring vehicle axle temperature during operation. Due to the vibration during the operation of passenger and freight vehicles, the infrared probe in the box will d...

AI Technical Summary

Problems solved by technology

[0007] 1. The specifications are relatively single and the applicability is poor

Since the metal support frame of the static calibration instrument currently used only has an insulator in a local position, it is easy to be over-charged when used on the rail surface of the railway, and accidents may injure the person and affect the track circuit, which has hidden dangers; the support frame does not have Set the adjustment device in the horizontal and vertical directions, the distance between the end of the support frame and the vertical support rod cannot be adjusted, so it can only be adapted to the calibration detection of a single type of infrared shaft temperature detection equipment for container and freight vehicles

That is to say, a standard calibration instrument is not compatible with various types of infrared axle temperature detection equipment for passenger and freight vehicles produced by different manufacturers, and can only be used for one type of infrared axle temperature detection equipment. The use, adjustment and maintenance of various types of infrared shaft temperature detection equipment bring a lot of inconvenience

[0008] 2. Poor positioning accuracy and poor calibration detection accuracy

Currently used calibration instruments, due to the connection of the movable part of the support frame or the connection of the movable part of the support rod, generally use ordinary cylinders or square bodies to cooperate with each other, and then use the top screw clamping structure, the movable part The connection and clamping positioning point is a design defect such as surface contact, and the matching accuracy between the connecting parts is poor, so the calibration detection error is large

The support frame is placed between the two rails and positioned by the surface contact of the left and right positioning baffles on it. The positioning reference is selected on the upper part of the base surface on the side of the rail that is easily worn by the wheel flange, which makes the positioning accuracy error of the calibration instrument very large. , therefore, resulting in poor calibration detection accuracy

[0009] 3. It can only calibrate temperature, not azimuth and angle

Since the position of the heat source of the cigarette butt or incense tip and the output of the instrument cannot be determined, the calibration error of the orientation is relatively large, and the accurate calibration of the orientation and angle cannot be performed, and it cannot be adapted to the calibration detection of multiple orientations and angles.
