AI Technical Summary

Technical Problem

The existing shaft temperature alarm test device cannot simulate the shaft working conditions, and the heat source temperature rises slowly, which affects the test efficiency.

Method used

A shaft temperature alarm sensitivity test device is designed, which drives the connecting pipe and the movable shaft to rotate through the motor, and combines the design of the connecting piston and the shaft holding plate to simulate the working conditions during the operation of the locomotive, and quickly increases the temperature of the surface of the movable shaft through friction.

Benefits of technology

The sensitivity test of the shaft temperature alarm can simulate the working conditions of the shaft, and shorten the detection time by rapid temperature increase, improving the testing efficiency.

Abstract

The utility model relates to the technical field of axle temperature alarm testing, and discloses an axle temperature alarm sensitivity testing device. The shaft temperature alarm sensitivity testing device comprises a bottom plate, an infrared temperature sensor is embedded in the center of the bottom plate, a motor is fixedly installed above the bottom plate, a fixing frame is embedded in the outer side of the motor, a connecting pipe is installed on the outer side of a rotating shaft of the motor in a penetrating mode, and a movable shaft is installed in the center of the connecting pipe in a penetrating mode. Connecting bolts are installed on the outer sides of the connecting pipes in a penetrating mode, the connecting plates are fixedly installed at the movable ends of the connecting pistons on the front side and the rear side of the bottom plate with the center of the bottom plate as the benchmark, the radian of the shaft sticking plate is matched with the movable shaft, and the connecting pistons can drive the shaft sticking plate to move through the connecting plates so that the shaft sticking plate can make contact with the rotating movable shaft. Certain relative pressure exists between the shaft sticking plate and the movable shaft, and the surface temperature of the movable shaft can be quickly increased under the influence of friction force, so that the heating time of a heat source is shortened, and the detection efficiency is improved.
