The invention relates to the technical field of mechanical engineering, in particular to a steel rail elongation measuring device for steel rail stress relief operation and a measuring method of the steel rail elongation measuring device. Measuring a device cross arm; a rail contact wheel. The measuring method specifically comprises the following steps: S1, disassembling a steel rail fastener, and putting a roller under a steel rail; s2, the whole equipment is fixed through fastening bolts; s3, rotating the cross arm of the measuring device, and resetting the encoder to zero; s4, the cross arm of the measuring device is put down, and zero resetting of the encoder at the cross arm of the measuring device is completed; s5, the encoder at the cross arm and the encoder at the base record data, signals are processed, and real-time steel rail elongation information is obtained; and S6, after single-time operation is completed, the steps are repeated. Compared with the prior art, the method has the advantages that the encoder is matched with the roller to measure the elongation of the steel rail, and the accuracy of the whole measuring means is greatly improved. And the labor force required in the stress relief operation process is reduced. And the number of construction materials involved in the construction process is reduced.

    本发明涉及机械工程技术领域,具体来说是一种钢轨应力放散作业钢轨伸长量测量装置及其测量方法,包括:测量装置底座;测量装置横臂;钢轨接触轮。测量方法具体如下:S1.拆解钢轨扣件、在钢轨下垫放滚筒;S2.通过紧固螺栓完成整体设备固定;S3.旋转测量装置横臂,编码器归零复位;S4.将测量装置横臂放下,完成测量装置横臂处编码器归零复位;S5.横臂处编码器、底座处编码器记录数据,信号处理、得出实时钢轨伸长量信息;S6.完成单次作业后,重复上述步骤即可。本发明同现有技术相比,其优点在于:采用编码器配合滚筒作为测量钢轨伸长量的方式,极大提升了整体测量手段的精确性。减少应力放散作业过程中所需的劳动力。减少施工过程中涉及施工物料数目。
