Railway vehicle length measuring device with hook buffer device

The utility model belongs to the technical field of rail transit, and particularly relates to a rail vehicle length measuring device with a hook buffer device. The railway vehicle length measuring device with the hook buffer device is provided with two bases fixed on a track, and the two bases are located at the two ends of a vehicle needing to be measured respectively. The base is perpendicular to the track, and a clamping block used for being clamped with the track is arranged on the lower portion of the base. The base is provided with a stand column perpendicular to the base. In the stand columns of the two bases, one stand column is provided with a laser range finder, and the other stand column is provided with a reflector. According to the utility model, the influence of ground flatness and trench arrangement in an operation field is avoided; and the measurement precision is obviously improved. 本实用新型属于轨道交通技术领域，具体涉及一种带钩缓装置的轨道车辆长度测量装置。涉及的一种带钩缓装置的轨道车辆长度测量装置具有两个固定在轨道上的底座，且两个所述的底座分别位于需测量车辆的两端；所述的底座垂直于轨道设置，并在底
