Description

Subway bolt disassembly-free torque detection device and method Technical Field The invention relates to the field of machinery, in particular to a subway bolt disassembly-free torque detection device and method. Background In the subway operation and maintenance process, the bolts are used as key connecting pieces, and the fastening state of the bolts directly relates to the operation safety and the service life of the train. In the running environment of high-frequency start-stop and complex vibration of the subway for a long time, the problems of loosening, torque attenuation and the like of the bolts are very easy to occur, and if the problems can not be found and treated in time, serious safety accidents such as falling off of train parts and electrical faults can be possibly caused. Meanwhile, bolts are widely distributed and complex in working condition, a plurality of parts such as a car body, a bogie and electrical equipment are covered, the bolts at different parts have different torque requirements, and the detection environments have larger differences, such as dim light in a tunnel, narrow space at the bottom of a train and the like, so that a plurality of challenges are brought to the detection of the torque of the bolts. Traditional bolt torque detection mainly relies on manual inspection and torque wrench detection, and in subway maintenance scenes, a screw-up method is often adopted to inspect the bolt torque, namely, the torque is steadily increased by a wrench, and the torque change during bolt rotation is observed to judge the fastening state. The traditional detection method has the defects that firstly, the traditional detection method has low efficiency and insufficient precision, the manual screw-on method depends on experience, has low efficiency and large deviation, is easy to miss detection and false detection, is difficult to operate in a hidden or narrow space, is easy to damage parts, cannot monitor and record data in real time, and is unfavorable for long-term tracking analysis. Secondly, the existing tools are obvious in limitation, most of the tools are large in size, poor in operation flexibility and weak in capability of adapting to complex environments, bolts are partially detached, the flow and damage risk are increased, the intelligent level is low, only single measurement can be achieved, and the operation and maintenance informatization requirement cannot be met. And moreover, the existing tool lacks customized design, the universal tool is not suitable for the characteristics of multiple specifications and multiple working conditions of subway bolts, the sleeve is single and needs to be replaced frequently, the vibration environment is not optimized, the detection is easy to interfere, the detection speed is low, the endurance is short, and the quick and comprehensive detection is difficult. In addition, due to the limitations of subway running environments and self structures, when bolts in narrow spaces, gap spaces and different installation directions are monitored in the detection process, the front end of a tool is difficult to contact the bolts, so that detection cannot be implemented. Therefore, the defects of the traditional detection device and method lead to low efficiency, insufficient precision and high operation risk ‌ of subway bolt detection ‌, and comprehensive and real-time state monitoring and data management are difficult to realize. The detection process is easy to leak detection and misjudge, the hidden part is difficult to operate and possibly damages parts, and is difficult to rapidly and comprehensively detect, the operation and maintenance safety and the intelligent level ‌ are influenced in the ‌ long term, and the operation and maintenance cost and the potential safety risk are increased.
