AI Technical Summary

Problems solved by technology

The document does not describe the existence of any mechanical structure capable of resisting the lifting of the pantograph, so an analysis of the opening and closing of the overall function of the pantograph is not possible
In addition, since there is no mechanical structure that can resist the lifting force generated by the pantograph actuation element, dynamic feature evaluation can only be performed when the pantograph is in contact with the catenary
Therefore, the influence of pantograph height and catenary contact on dynamic feature evaluation is ignored

Embodiment Construction

[0111] refer to figure 1 , a preferred embodiment of the device 1 for inspecting railway pantographs according to the invention comprises a mechanical structure 2 . The above-mentioned mechanical structure 2 is provided with an axis of symmetry, and is also symmetrical with respect to two mutually orthogonal main planes including the above-mentioned axis of symmetry. Said mechanical structure 2 comprises a main body 100 equipped with all the components necessary for the function provided by the device 1 and a series of connection structures 200 designed to connect the main body 100 to the frame of the pantograph , and in this exemplary embodiment, the connecting structure 200 includes four structural elements or legs that are equivalent to each other.

[0112] The main body 100 shows a parallelepipedal envelope that approximates a cube. The profile is oriented such that the base surface is normal to the axis of symmetry and each of the two pairs of side surfaces is parallel ...

Abstract

A semiautomatic (1) sensorized apparatus for the execution of inspections of the railway pantograph (P) is detachably associated to a railway pantograph and allows the execution of two distinct tests in succession: i) the first one, which monitors the functional properties of the pantograph, based on the characterization of the thrust force generated by the main suspension; and ii) the second, which aims to identify global and local defects, adopting the principle of inspection by means of vibration analysis.

Description

technical field [0001] The invention relates to the technical field of railway pantograph detection equipment, in particular to state-based semi-automatic maintenance equipment. Background technique [0002] The advent of high-speed (HS) train railways requires the introduction of technologies for managing and processing traffic-related information. In particular, components whose performance and safety are determined form the subject of a digital definition of their characteristics throughout the life cycle of the component, with particular emphasis on maintenance. Traditional preventive maintenance is often replaced by predictive or condition-based maintenance for those components where the average cost of repair and / or replacement is comparable to the cost of any downtime. [0003] Among the train components to which this model can be applied, the railway pantograph is of crucial importance. This part performs the basic function by connecting the power circuit of the el...
