Steel rail line type detecting device of railway line

The utility model relates to a steel rail line type detecting device of a railway line, which is convenient to carry and detect and high in detecting accuracy and is composed of a driving line-adjusting clamping-connecting mechanism and a driven line-adjusting clamping-connecting mechanism. One end of a line is wound on a line wheel by the driving line-adjusting clamping-connecting mechanism, tightened through rotating winding and located at the position 14-18 meters lower than a steel rail head through support of a line-adjusting rod, and simultaneously a distance between the line and the steel rail head is adjusted. One end of the line is fixed by the driven line-adjusting clamping-connecting mechanism and located at the position 14-18 meters lower than the steel rail head through the support of the line-adjusting rod, and simultaneously the distance between the line and the steel rail head is adjusted. The steel rail line type detecting device of the railway line has the advantages that 1 due to the fact the line is a high strength line, the problem of large arc formed during long-distance measurement is solved, and measurement accuracy is improved remarkably; and 2 a clamping head is manufactured according to the outline of the steel rail head and is clamped on the rail head by using a fastening shaft when installed, and the line-adjusting rod is arranged on the lateral side.
