Description
Technical field
This utility model relates to steel rail flaw detection technology field, particularly relates to a kind of steel rail welding line scanning equipment.
Background technology
Construction and train speed raising, train density increase along with China Express Railway and overlength seamless railway, in-service rail failure and steel rail welding line development of defects speed is made to accelerate, wherein the trauma in steel rail welding line region accounts for about the 60% of whole trauma, and has the trend of growth.
Rail welding mainly has factory's weldering, on-the-spot gas pressure welding and exothermic welding three kinds.Due to the impact of the factors such as welding method, technique and material, weld seam often occurs Dangerous defect, is broadly divided into volume shape defect peace planar defect.In use, weld seam also has original manufacturing defect and fatigue failure.If these defects detect not in time, it is possible to cause brittle fractures of rail, seriously jeopardize safe train operation.
At present, domestic steel rail welding line crack detector mainly has simulation seam inspection instrument and general digital crack detector two kinds.Instrument is mainly to separate the manually flaw detection of single probe, and for the defect of different orientation, the different probe that changes the outfit detects respectively, and method is not comprehensive, and complex operation is consuming time longer.Additionally defects detecting technology comparatively complete, specification is not designed among software and hardware (including ultrasound probe) by instrument, lacks ability of comprehensively detecting a flaw.Each Railway Bureau can only formulate flaw detection management method and technique under the existing functional conditions of instrument, causes that steel rail welding line is detected by many people multiple stage instrument, complex process, inefficiency.In the last few years, instrument is improved by instrument manufacturer facility man according to the requirement of user, and what have adds probe socket for instrument, but only address only the trouble repeatedly changing probe；Have for apparatus preparation Type B scanning frame, but function is simple, vertical defect is detected only by single K type scanning, and scanning scope is little, the scope (requirement of TB/T2658.21-2007 " work business operation the 21st part: steel rail welding seam ultrasonic inspection operation " seam inspection standard) of such as scanning 400mm, then need scanning 20 times.
In addition, needs due to information system management, user emphasizes the writing function of flaw detection data especially, current seam inspection instrument does not also possess the whole-process automatic writing function of data and the playout software of specialty, flaw detection operation is by manual record, verity can not be ensured, is unfavorable for data sharing and information system management.
The industries such as weld seam supersonic detection instrument in the market mostly is general weld seam ultrasonic reflectoscope, advantage: carrying portable, is suitable for and Aero-Space, boats and ships, railway, boiler.Shortcoming: 1. adopt single probe flaw detection mode that operator's professional skill is required height.Owing to rail is big to ultrasonic attenuation and noise is high, trauma not easily finds, it is necessary to operator have very abundant field experience to differentiate trauma, and therefore trauma recall rate is low, and on-the-spot flaw detection operation quality is directly limited by the technical merit of site operation personnel；2. inadequate for the special industry tailored version of railway weld seam, complicated weld seam is not had effective detection means.Such as lossless fixture reinforced weld, this weld seam cannot be detected by traditional single probe scanning；3. not having field operation process recording and flaw detection data record, manager is low to field personnel's operation quality ability to supervise.4. menu is loaded down with trivial details, and parameter regulates time-consuming, is unfavorable for on-the-spot sharp work, and working performance is low.
In sum: there is presently no user's desirably total digitalization specialty heads for crank detection of ultrasonic bonding lines instrument both at home and abroad.Develop a kind of detection means is complete, recall rate is high, speed of detection is fast steel rail welding line method of detection and defect-detecting equipment, be those skilled in the art's urgent problems.
