A bridge steel cable vibration detection device comprises a clamping mechanism, a lifting mechanism, a measurement mechanism, and a monitoring unit, wherein the clamping mechanism utilizes adjusting component to control the operation of two pairs of arm assemblies, causing the saddles located on opposite sides to approach each other, thereby bringing the active component and passive component of the lifting mechanism on both sides of the saddles into contact with the steel cable. The passive component applies pressure to the steel cable through elastic element, allowing the active and passive components to appropriately clamp the steel cable. The active component is driven by power element to make the active and passive components roll and climb along the steel cable to a predetermined position, and a laser rangefinder is used to determine the height of the vibration detection device. The measurement mechanism utilizes the forward-pushing characteristic of electromagnet to pressure the sensor against the stee
