High-precision inclinometer for measuring rail height difference and measuring method thereof

The invention discloses a high-precision inclinometer for measuring rail height difference and a measuring method thereof, and belongs to the technical field of inclinometers. According to the high-precision inclinometer for measuring the rail height difference and the measuring method thereof, the high-precision inclinometer comprises an inclinometer main body and further comprises four inclination angle pulleys, the inclination angle pulleys are installed on the periphery of the inclinometer main body, and a screen shell plate is arranged on the surface of one side of the inclinometer main body. In order to solve the problem that after a gyroscope in an inclinometer is used for long-time measurement, a tension spring structure formed in the inclinometer generates metal fatigue under continuous stretching and contraction, so that errors are generated in the using process of the inclinometer, after measurement is completed, the face, provided with a display screen, of an inclinometer body is placed upwards, a
