When Chen Zhiyong, the person in charge of the work, pushed the railway fault detection vehicle across the tracks, the waveforms on the instruments began to pulse. \u201c\u8fd1\u671f\u5217\u8f66\u73ed\u6b21\u8f83\u591a\uff0c\u73ed\u6b21\u7d27\u5f20\u3002\u8bf7\u5c0f\u5fc3\u6ce2\u5f62\u5f02\u5e38\u3002\u201d\u4e09\u540d\u5de5\u4eba\u64e6\u7740\u6c57\uff0c\u4ed6\u63d0\u9192\u9053\u3002\u4ed6\u4eec\u8f7d\u7740\u51e0\u5341\u516c\u65a4\u7684\u6c7d\u8f66\uff0c\u6500\u722c\u4e00\u767e\u5757\u87ba\u65cb\u77f3\u7070\u5ca9\u624d\u5230\u8fbe\u5927\u6865\u3002

\n From time to time, mosquitoes circled around the light on Chen Zhiyong’s head, and some of them were still lying on his face, ready to bite him. But he was always focused on the image of the instrument, his fingers moving between the keys. He did not slow down until a scissor-shaped steel structure appeared on the tracks.
\n “This is a telescopic rail adjuster consisting of a base rail and a tip rail. The adjuster is connected to the bridge with this ‘scissors’ structure andIt can expand and contract freely depending on temperature changes to prevent the track from being deformed due to temperature changes. During operation, the probe of the fault detection vehicle emits ultrasonic waves from various angles to the rail. The waveform is analyzed to check for damage inside the adjuster.\u201d\u9648\u5fd7\u52c7\u5b89\u88c5\u5b8c\u6bd5\uff0c\u7ee7\u7eed\u6211\u7684\u5de5\u4f5c\u3002\u68c0\u67e5\u8bbe\u5907\u3002

He turned the probe adjustment knob clockwise several times by hand, stood up and said to Dong Peiwei: “Retry the test.”
\n “This is not damage. This is because the probe was displaced in the connecting part of the straight rail and the tip rail after the equipment entered the regulator. It needs to be manually adjusted.” Chen Zhiyong explained as he saw the red line on the screen disappear.
\n “Many trains will pass during the holidays, so please stay alert and check the status of the equipment carefully. Your attitude is enough.” After Chen Zhiyong explained to Dong Peiwei, he turned around and started jogging, then returned to his original position.and continued working.
\n In follow-up work, Chen Zhiyong and his colleagues completed fault-finding inspections on eight sets of telescopic rail adjusters and found no damage. I returned to the dormitory by bus around five o’clock in the afternoon and inspected the “massage device” on the railway bridge that will continue to protect the safe movement of passengers. \uff08\u5b8c\uff09
