摘要： The invention relates to a bridge exciter for inducing vibrations in railway or roadway bridges, which comprises a servo-hydraulic actuator connected to a wagon designed to transport the same over tracks or a road. The actuator generates a force by moving a variable-weight reaction mass guided by linear bearings. It comprises hydraulic equipment that enables direct transmission of the vibrations to the infrastructure, independent of the rolling gear of the wagon or the rubber-tired vehicle, via false wheels. The movement of the actuator piston is controlled by a computer allowing the actuator to apply general forces on a bridge or roadway that do not exceed the maximum acceptable displacement of the piston: harmonic, impulsive, and transient forces. The equipment is provided with the necessary load control elements.

摘要： A method for in-situ and real-time collection and processing of geometric parameters of railway lines, in a particular but non-limiting manner to those related to the height and stagger of the contact wire in electrified lines and the gauges to specific elements of the infrastructure in any line, generated based on static measurements starting from two-dimensional scenes perpendicular to the track axis, by determining the number of angular positions per scene, determining the minimum number of passes in each position, obtaining the raw coordinates, applying an averaging algorithm, applying offset corrections, transforming coordinates and applying either the steps to salve for height and stagger of the overhead contact line, or applying the steps to salve for gauges to specific elements of the infrastructure. An optimized, efficient and simple method is achieved which enables the real-time management and processing of the data obtained from the railway infrastructure.

摘要： A trolley for inspecting railway construction parameters having two frames, left and right, joined in a folding manner with a central body, wherein each frame is provided with a running assembly mounted on the free ends of the frames, wherein the running assemblies are foldable with respect to the frames and wherein a telescopic column emerges from the central body, the final section of which has a handle for operating the trolley and a tray for resting control equipment, such as a computer, wherein the tray is foldable with respect to the telescopic column and the latter is foldable with respect to the central body until it touches the top plane of the frames, forming a compact, portable assembly that can be operated by a single operator and is easy to operate.
