Multifunctional flaw detection vehicle for highland railway steel rail

Abstract

The invention provides a multifunctional flaw detection vehicle for a highland railway steel rail. The multifunctional flaw detection vehicle for the highland railway steel rail comprises a tractor and a detection vehicle; the rear end of the tractor is connected with one end of the detection vehicle to drive the detection vehicle to move; a steel rail flaw detection device is installed on a front steering frame of the detection vehicle and a steel rail contour detection device is installed on a rear steering frame; a rail state routing inspection device is installed below the rear end frame of the detection vehicle; a vehicle set is assembled with advanced train control and communication equipment such as an ITCS and an INMARSAT telephone and successfully introduces the aviation oxygen generator technology. The multifunctional flaw detection vehicle for the highland railway steel rail has the advantages of being simple, reasonable and practical in structure, comprehensive in function, satisfying detection requirements for railway rail ultrasonic detection, a steel rail contour, the steel rail abrasion, the rail cant, a steel rail surface and lateral side and the fastener loss, being good in integral operation stability and satisfying the requirement for the highest continuous operation speed per hour of 80 kilometer per hour of the ultrasonic flaw detection flat rail under the highland environment.

Description

Technical field [0001] The invention belongs to the technical field of plateau railway rail maintenance equipment, and specifically relates to a multifunctional flaw detection vehicle for plateau railway rails, and is particularly suitable for rail flaw detection and detection with an altitude of 5100m or less and a maximum continuous operating speed of 80km / h on a straight track. Background technique [0002] With the opening and operation of the Qinghai-Tibet Railway, the inspection and maintenance of its lines and facilities are imminent. The inspection accuracy of the inspection of various damages inside the rail, the inspection of the line surface condition, and the precise measurement of the rail profile is also constantly improving. The Qinghai-Tibet Railway Gera Line is located in the hinterland of the Qinghai-Tibet Plateau, with severe climatic conditions such as high altitude, low air pressure, hypoxia, high cold, large temperature difference, and large wind and sand. It...

Problems solved by technology

In order to do a good job in the research and development of the Qinghai-Tibet company's flaw detection vehicle, the relevant departments of the former Ministry of Railways reviewed the plan, requiring that while solving the power capacity problem, fully consider the special climate and line conditions of the Qinghai-Tibet Railway, and put high reliability in the first place in the development. On the premise of ensuring reliability and taking into account the advanced nature, the existing plateau flaw detection vehicle cannot meet the requirements in terms of speed and structure, especially the power unit and testing equipment are placed on the same vehicle, and noise and vibration have a great impact on the testing equipment , leading to inaccurate detection results, and when the flaw detection vehicle is operating, the driver and passengers have to board and stay on the vehicle for a long time, and there are no perfect living facilities on the vehicle. Therefore, the research and development of the flaw detection vehicle for the Qinghai-Tibet Plateau operation is imperative
