The invention discloses a miniature constant-tension winch displacement measuring device which comprises a winch body, and the winch body comprises a hollow winch roller. A spiral groove is formed in the outer side wall of the hollow winding roller in the circumferential direction, a steel wire rope with the diameter larger than 8 mm is wound around the spiral groove, and the outer end of the steel wire rope is connected with a measured object. A coupler, a planetary reducer and a servo motor are arranged in the hollow winch roller, the output end of the servo motor is connected with an input shaft of the planetary reducer, and an output shaft of the planetary reducer is connected with the hollow winch roller through the coupler. The servo motor is connected with a servo driver which is used for collecting working parameters of the servo motor, calculating the elongation length of the steel wire rope according to the reduction ratio of the planetary reducer and the diameter and lead parameters of the spiral groove of the hollow winch roller, driving the servo motor to work and keeping the constant tension of the steel wire rope. The problem of measurement failure in a severe environment can be effectively solved.
