Abstract

The present invention relates to the technical field of escalator testing, and specifically to an escalator step torsion test measuring device and method. An escalator step torsion test measuring device is used to measure the displacement of the step, and includes a measuring piece, a first sensor and a second sensor. One end of the measuring piece is set to a measuring block in a cube shape. After the measuring block is connected to the step, one side of the measuring block is horizontal and the other side is vertical. The first sensor is arranged above the horizontal plane, and the second sensor is arranged in front of the vertical plane. The first sensor and the second sensor can respectively measure the displacement of the measuring block in the horizontal and vertical directions, and measure the length of the arc along the center of the follower roller centered on the center of the step chain roller in real time according to the geometric relationship formula and through computer calculation. The vibration of the measuring block is synchronized with the vibration of the center of the follower roller. The setting of the measuring block facilitates the measurement of the real-time displacement of the follower roller.
