Data transmission line traction equipment for track deformation monitoring in railway tunnel

The utility model discloses data transmission line traction equipment for track deformation monitoring in a railway tunnel, which comprises a fixed base, a top box is movably mounted at the top of the fixed base, a traction mechanism is movably mounted in the top box, and two support columns are fixedly mounted at the top of the fixed base. According to the utility model, the traction mechanism and the electric push rod are arranged, and the output shaft of the electric push rod slowly moves upwards to drive the moving plate to move upwards, so that the limiting column moves upwards, the limiting column is inserted into the limiting groove, and the limiting column limits the data transmission line and has a certain fixing effect on the data transmission line; the situation that a cable wound on the winding body is loose can be prevented, and the situation that when the electric push rod is pushed upwards, the electric push rod cannot sense the pressure value between the limiting column and the limiting groove
