The invention belongs to the technical field of water conservancy gates, and particularly relates to a hanger shaft monitoring device for a hydraulic opening and closing gate. Guide wheel supports are additionally arranged on the two sides of a counterweight assembly, and the guide wheel supports are arranged on a limiting device base below the counterweight assembly through bolts. The guide wheel support comprises a base, a vertical rod is arranged on one side of the base, and a rotatable guide wheel is transversely arranged in front of the upper end of the vertical rod. On the basis that an original structure is kept, two sets of guide wheel support devices which are symmetrical left and right are additionally arranged to position a balancing weight and play a guiding role in the vertical operation process, and guide wheels support the balancing weight in the gate falling process so that a guide rod can not incline or be clamped. The guide wheel support seat adopts a kidney-shaped groove ...
