Hand-held steel rail and turnout crack depth measuring instrument based on eddy current principle
The invention belongs to the technical field of measuring instruments, particularly relates to a handheld steel rail and turnout crack depth measuring instrument based on an eddy current principle, and aims to solve the problems that an existing measuring instrument does not have a protection function, if the existing measuring instrument falls off during handheld use, a measuring instrument body is easily seriously damaged, economic loss is caused, and the detection working efficiency is influenced. According to the technical scheme, the measuring instrument comprises a measuring instrument body, a detection head is arranged on the measuring instrument body and comprises a probe connector, a probe shell, a sensor and a ceramic measuring surface, the top and the bottom of the measuring instrument body are movably connected with a top cover shell and a bottom cover shell respectively, and a through hole is formed in the top of the top cover shell; the detection head is movably connected with the through hole. The measuring instrument is simple in structure and convenient to operate, the measuring instrument body can be fixed and protected conveniently, the degree of damage caused when the measuring instrument body falls can be reduced, meanwhile, too large loss can be avoided, and the influence on the detection work efficiency is avoided.
本发明属于测量仪技术领域，尤其是基于涡流原理的手持式钢轨及道岔裂纹深度测量仪，针对现有的测量仪不具有保护功能，在手持使用时如果发生掉落，容易对测量仪本体造成严重的损坏，造成经济损失，同时影响探测工作效率的问题，现提出如下方案，其包括测量仪本体，测量仪本体上设置有探测头，探测头包括探头连接器、探头外壳、传感器和陶瓷测量表面，测量仪本体的顶部和底部分别活动连接有顶部盖壳和底部盖壳，顶部盖壳的顶部开设有通孔，探测头与通孔活动连接。本发明结构简单，操作方便，便于对测量仪本体固定保护，可以降低测量仪本体掉落时造成损坏的程度，同时可以避免造成过大的损失，避免影响探测工作效率。
