The invention discloses arch bridge deflection measuring equipment, and relates to the technical field of bridge deflection measurement. Displacement releasing parts are arranged on the two sides of the laser position measuring part, and the displacement releasing parts are movably connected with the double-station hanging connection structure in a matched mode; the displacement releasing part is in a vertical long groove shape, a first trapezoidal block is arranged at the top end of the displacement releasing part, a second trapezoidal block is arranged at the bottom end of the displacement releasing part, a double-inclined-plane block sliding in the groove is arranged in the middle of the displacement releasing part, inclined planes of the first trapezoidal block and the second trapezoidal block are located on the upper portion, inclined planes are arranged on the upper portion and the lower portion of the double-inclined-plane block, and an embedding groove is formed in the lower portion of the first trapezoidal block; the straight face of the extrusion block abuts against the lower face of the first trapezoidal block in a clamped mode, the upper inclined face of the double-inclined-face block can be embedded into the embedding groove in shape to form an embedding body, and the extrusion block can slide through the embedding body to be separated from the displacement disengaging part. The laser position measuring part can be flexibly and rapidly placed through the unmanned aerial vehicle, three-dimensional construction of all point positions of the bridge body is carried out, and the deflection of the arch bridge is rapidly and efficiently measured.
