Steer frame of flaw detection trolley of freight heavy railways

Abstract

The invention relates to the technical field of railway vehicle manufacturing, specifically to a steer frame of a flaw detection trolley of freight heavy railways. The steer frame comprises a H-shaped support frame, wherein a rolling wheel pair is arranged at the lower sections of the two ends of the support frame, and flexible fixing pins are fixedly arranged on the outer side of the axle box of the wheel pair; a suspension beam of the flaw detection trolley is fixedly arranged between the flexible fixing pins, and the flaw detection trolley is fixedly installed at the suspension beam of the flaw detection trolley; basic driving mechanisms are fixedly arranged on the two sides of the frame beam of the support frame, and the middle of the support frame is provided with a hanging mechanism; a towing hole is formed in the middle of the frame beam, and a central pin is plugged into the towing hole in a cooperating connection mode. Since the steer frame of a flaw detection trolley of freight heavy railways can conduct flaw detection operations at the same speed as the moving speed of the steer frame, the flaw detection efficiency is greatly improved, the manual transport of the flaw detection device is avoided, and the labor intensity of workers is greatly reduced while the flaw detection precision of steel rails is significantly improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing railway locomotives, in particular to a bogie of a freight heavy-duty railway flaw detection car. Background technique [0002] With the development of the domestic economy, domestic railway lines for heavy-duty freight transportation are increasing, and the frequency of railway use is becoming more and more intensive. The damage to rails on freight roads is also becoming more and more serious. Therefore, it is of great significance to strengthen the detection of railway rails for timely repair to ensure the safe operation of railway freight. At present, most railway rails are inspected manually. The efficiency of manual inspection is low, the labor load is large, and the accuracy of inspection is not satisfactory, which brings a lot of inconvenience to the inspection of freight heavy-duty railway rails. Contents of the invention [0003] The purpose of the present invention is to overcom...
