The invention discloses a bridge crack measuring device and method for municipal bridge engineering, and relates to the technical field of bridge engineering, and the device comprises a vehicle bottom plate, Mecanum wheels, and a driving mechanism connected with the Mecanum wheels. The device further comprises a control box, a convex frame, an angle adjusting mechanism, a deflection detection mechanism, a linear driving mechanism, a bridge crack detector, a storage battery, a controller, a first visual sensor and an infrared sensor. The method comprises the steps that the deflection detection mechanism is used in cooperation with the bridge crack detector, and the controller comprehensively evaluates the safety risk level of the crack according to information transmitted by the deflection detection mechanism and the bridge crack detector. According to the invention, the deflection, width and depth of the bridge crack can be comprehensively detected, so that the detection result has higher reference value, and
