Portable wire rope length measurement device

The invention relates to a portable wire rope length measurement device, which solves the problem that operation is difficult and the accuracy of measurement is not high when a ruler is used for manually measuring the length of a wire rope. The portable wire rope length measurement device comprises an upper cover (7), a lower cover (13) and a control circuit (8), the positions of the upper cover (7) and the lower cover (13) are limited by horizontal upper cover and lower cover positioning pins (1) and upper cover and lower cover locking springs (3), handles (12) are arranged on the outsides of the upper cover (7) and the lower cover (13), four guide rollers (2), a pinch roller (9) and a shaft-pressing spring (11) are arranged in the lower cover (13), a measuring roller (5) is arranged in the upper cover (7), the measuring roller (5) is coaxially connected with an encoder (4), the encoder (4) is connected with the control circuit (8) through a wire (6), and the encoder (4), the wire (6) and the control circuit (8) are arranged outside the upper cover (7). The portable wire rope length measurement device is used for measuring the length of a wire rope.
