Steel rail elastic strip buckling pressure detection device and method
The invention provides a steel rail elastic strip buckling pressure detection device. The steel rail elastic strip buckling pressure detection device comprises a self-checking knocking hammer, a temperature vibration sensor and a handheld measuring instrument, wherein a pressure sensor array is arranged in a hammer head of the self-checking knocking hammer, and when the self-checking knocking hammer knocks a first side limb of the steel rail elastic strip, the pressure sensor array is used for detecting the knocking force and the knocking angle; the temperature vibration sensor is attached and fixed to a second side limb of the steel rail elastic strip and used for detecting the temperature and vibration data of the steel rail elastic strip; a temperature vibration signal acquisition card, a data storage card and a controller are arranged in the handheld measuring instrument, a data display screen is arranged, and a correlation database between elastic strip buckling force and vibration frequency in different temperature environments is stored in the data storage card. The invention further provides a method for detecting the buckling pressure by adopting the device for detecting the buckling pressure of the steel rail elastic strip, the detection difficulty of the buckling pressure of the steel rail elastic strip can be reduced, and the detection precision can be improved.
本发明提供了一种钢轨弹条扣压力检测装置，包括自检式敲击锤、温振传感器，以及手持式测量仪；其中，自检式敲击锤的锤头内置有压力传感器阵列，在自检式敲击锤敲击钢轨弹条的第一侧肢时，压力传感器阵列用于检测敲击力度和敲击角度；温振传感器贴装固定于钢轨弹条的第二侧肢上，用于检测钢轨弹条的温度和振动数据；手持式测量仪内置温振信号采集卡、数据存储卡、控制器，并设有数据显示屏，数据存储卡内储存有不同温度环境中弹条扣压力与振动频率间的关联数据库。本发明还提供了一种采用上述钢轨弹条扣压力检测装置进行扣压力检测的方法，能够降低钢轨弹条扣压力的检测难度，提高检测精度。
