A device and method for measuring and monitoring the inclination angle of a pantograph carbon sliding plate

Abstract

The invention discloses a measurement monitoring device and method for the inclined angles of a pantograph and a carbon slider. The device comprises the pantograph, the carbon slider, and further comprises a coupler, an angle transducer, a processing module, a communication interface, a central processing unit, a stepping motor and a steel wire rope, which are connected sequentially, as well as a carbon slider rotating shaft. According to the invention, the angle transducer is connected with the pantograph and the carbon slider through the coupler, so that the angle transducer and the pantograph rotate simultaneously, and the more accurate angle is measured; meanwhile, according to the inclined angle of the pantograph, the wear condition of the carbon slider can be judged, the pantograph can be detected and replaced timely, and the pantograph scraping can be avoided; in addition, since the stepping motor is arranged, the inclined angle of the inclined angle can be adjusted properly, therefore, the service life of the carbon slider is prolonged, the cost is reduced, and meanwhile, railway accidents can be prevented effectively.

Description

Technical field [0001] The invention belongs to the field of circuit design, and specifically relates to a pantograph carbon sliding plate inclination measurement and monitoring device and a method thereof. Background technique [0002] The pantograph is also called the pantograph, and is also called the power transmission frame. It is a general term for the equipment that allows electrified railway vehicles to obtain power from overhead cables. Generally, it can be divided into single-arm bow and double-arm bow. Both are composed of collector head, upper frame, lower arm rod (lower frame for double-arm bow), underframe, bow spring, transmission cylinder, support insulator and other components. , The bow head of the pantograph is equipped with a removable carbon or powder alloy conductive sliding plate, which is in contact with the contact net to get electricity. [0003] With the development of the railway industry, there are more and more applications for high-speed railways and...

Problems solved by technology

[0004] During the operation of the pantograph, the carbon slide plate will wear too fast. The bottom of the catenary section of many new railways is arc-shaped, and the surface of many contact wires is too hard, which will easily cause the wear of the carbon slide plate; A certain contact pressure is always required to ensure that the locomotive receives current in good condition. When the contact pressure is too small or even zero, the carbon slide of the pantograph will break away from the catenary and go offline. Sparks or arcs will be generated at the moment of offline, increasing the Reduces electrical wear of contact wires and pantograph carbon slides and shortens service life

[0005] The eccentric wear of the carbon skateboard is also one of the important reasons that affect the life of the carbon skateboard. When the carbon skateboard is eccentrically worn, it is easy to cause the carbon skateboard to wear through, so that the carbon skateboard forms grooves and sticks to the contact line, resulting in scraping the bow. The appearance of the scraping bow is easy to damage The pantograph will cause insufficient power supply of the train or directly fail to run, and even the pantograph will cut off the contact wire, so that the entire running line cannot be powered, resulting in greater losses. Therefore, how to detect the carbon slide plate of the pantograph has become a Problems to be Solved Urgently in Preventing Train Accidents
