Description

Technical Field

[0001] The utility model belongs to the technical field of sensor testing, and in particular relates to a railway turnout conversion force sensor testing device. Background Art

[0002] In the railway transportation system, turnouts are key switching devices, and the stability and reliability of their operating status are directly related to the safety and efficiency of train operation. Turnout switching force refers to the resistance that the turnout needs to overcome during the switching process. The accurate measurement of this parameter is of great significance for evaluating the operating status of the turnout, preventing failures, and optimizing maintenance strategies. The turnout switching resistance sensor is a device used to detect the size of the resistance during the turnout switching process. It is mainly installed on the turnout switching device. When the turnout is switched, the sensor can sense the change in resistance in real time. This helps to timely detect whether the turnout conversion is smooth. For example, when there is a foreign object stuck or a mechanical component fails, causing an abnormal increase in resistance, the sensor can feed back the signal to the relevant monitoring system. By analyzing these signals, railway maintenance personnel can perform maintenance and repairs in advance to ensure the normal operation of railway turnouts and improve the safety and reliability of railway operation. Traditional turnout switching force sensor testing often involves complex disassembly and installation processes, relies on manual operation, has low testing efficiency, and low measurement accuracy.
