The utility model relates to a weld joint correcting device suitable for a rail transit steel rail drop weight test, which comprises a bottom plate, a top plate, a synchromesh gear, clamping plates and a guide pillar, the clamping plates extend downwards, the guide pillar is connected with the bottom plate in a left-right sliding mode, the guide pillar is a polygon prism, each clamping plate is provided with a rack extending left and right, and the two racks are meshed with the front side and the rear side of the synchromesh gear respectively. A reset mechanism is arranged on the bottom plate and used for driving the two clamping plates to get close to each other, a laser range finder is arranged at the top of the top plate, and the pointing axis of the laser range finder is parallel to the axis of the synchronous gear. The clamping plates are symmetrically arranged to ensure that the laser range finders on the top plate are located on the sliding rail axis of the drop hammer, the laser range finders are used
