The invention provides a wheel rail friction heat flash temperature measuring device, and relates to the technical field of indoor test devices. The wheel rail friction heat flash temperature measuring device comprises a placing mechanism and a data acquisition module, a control mechanism is fixedly arranged at the center of the front face of the placing mechanism, a steel rail fixing mechanism is fixedly arranged at the center of the front end of the upper surface of the placing mechanism, and a supporting mechanism is fixedly arranged at the center of the rear end of the upper surface of the placing mechanism. An infrared temperature measuring mechanism is fixedly arranged at the upper end of the supporting mechanism, an adjusting mechanism is fixedly arranged at the upper end of the infrared temperature measuring mechanism, and a wheel fixing mechanism is rotationally arranged in the middle of the upper end of the front face of the adjusting mechanism. The pure sliding working condition of the wheel along the steel rail is simulated through friction between the steel rail test piece and the simulated wheel, accurate temperature control of the wheel and the steel rail test piece can be achieved through the two heating plates, sliding friction of the wheel rail at different temperatures is simulated, and the device is simple in overall structure, convenient to maintain and repair, wide in application range and higher in practicability.
