Railway track bearing rigidity testing device and using method
The invention provides a railway track supporting rigidity testing device and a using method, and belongs to the technical field of rail rigidity testing, the railway track supporting rigidity testing device comprises a testing pillow, a sleeper and a steel rail, jacks are fixedly connected to the two sides of the testing pillow, a stress beam is arranged between the tops of the jacks on the two sides, and a force measuring sensor is fixedly connected to the middle of the stress beam; the ends, away from the stress cross beam, of the force measuring sensors are fixedly connected with counter-force rods, clamps are clamped to the two sides of the steel rail, displacement meters are fixedly connected to the two sides of the top of the sleeper, and high-pressure oil pipes are fixedly connected to the side walls of the two jacks. According to the device, the jack oil pump is used for simultaneously controlling ejection of the two jacks, so that equal loads can be simultaneously applied to the steel rail from the two sides, the test pillow is subjected to equal counter-acting force, the loads with the same size are simultaneously applied to the two sides, the situation that the test pillow tilts on one side in the stress application process can be effectively avoided, and the test accuracy is improved. Therefore, the testing accuracy of the device is improved.
本发明提供了铁路轨道支承刚度测试装置及使用方法，属于铁轨刚度测试技术领域，包括测试枕、轨枕、和钢轨，测试枕两侧均固定连接有千斤顶，两侧千斤顶顶部之间设置有受力横梁，受力横梁中部固定连接有测力传感器，测力传感器远离受力横梁的一端固定连接有反力杆，钢轨两侧均卡接有夹具，轨枕顶部两侧均固定连接有位移计，两个千斤顶侧壁均固定连接有高压油管；该发明本装置通过一个千斤顶油泵同时控制两个千斤顶顶出，从而能够同时从两侧对钢轨施加均等的荷载，使得测试枕受到均等的反作用力，而且两侧同时施加相同大小的荷载，能够有效避免加力过程中测试枕存在单边翘起的情况，从而提高了该装置测试的精准度。
