Steel wire rope diameter detection device

The utility model relates to a steel wire rope diameter detection device which comprises a supporting assembly and a measuring rod. The supporting assembly comprises a vertical rod and a transverse rod, one end of the vertical rod and one end of the transverse rod are connected and perpendicularly arranged, and a plurality of inserting openings with downward openings are formed in the transverse rod from left to right. The top surface of the measuring rod is provided with an insertion block, and the insertion block is matched with the insertion opening. One surface, opposite to the vertical rod, of the measuring rod is divided into a first measuring surface, a second measuring surface and a third measuring surface from bottom to top, and the first measuring surface, the second measuring surface and the third measuring surface are vertical surfaces. According to the utility model, the size of the gap between the measuring rod and the vertical rod is compared with the diameter of the steel wire rope, so that th
