Description
Technical Field
The invention relates to the field of steel rail welding in the railway industry, in particular to a steel rail flash welding automatic centering and measuring device arranged in a fixed steel rail flash welding machine.
Background
The smoothness of the steel rail welding joint is one of the factors of the steel rail flash welding quality, and is related to the stability and the safety of the train in operation and the workload of later maintenance. The fixed rail flash welding centering device is an important factor influencing the smoothness of a rail flash welding joint. At present, in a steel rail welding base or a production line of a welding rail factory in China, centering work before steel rail welding is finished mainly by a rigid shaft and a centering arm of a steel rail flash welding machine in a manual or semi-automatic mode, and a simple centering measuring device is designed in the welding rail factory, but the simple centering measuring device and the welding machine do not form closed-loop control, and the online recording function is not realized.
The known patent (Chinese patent CN100396421C) of a fixed steel rail flash welding machine is developed by China railway science research institute, and mainly carries out rail pre-welding centering through a three-level centering structure. The primary centering is mainly completed by adjusting the top point position of a rail bottom supporting wheel, the spiral depth of the top of a rail bottom vertical adjusting oil cylinder piston rod, the position of a rail bottom horizontal direction adjusting mechanism platform and the distance between a primary centering rail frame and a host; the secondary centering is mainly completed by adjusting a gasket at the top end of a piston rod of the rail waist horizontal clamping oil cylinder; the third-stage centering is mainly completed by driving the rack to move through a horizontal centering oil cylinder and a vertical centering oil cylinder. However, all actions of the device centering device disclosed in the patent are manually adjusted, and the device centering device is not provided with any measuring device, cannot realize automatic centering, automatic measuring and automatic recording functions, and has certain limitations in the aspects of centering precision and efficiency.
One known patent for a fixed contact butt welding rail machine (chinese patent 98105796.9) was developed by the ukrainian barton welding institute. The centering function of the welding machine in the patent is mainly to complete the manual or automatic centering function through mechanical and hydraulic components such as an automatic centering roller, a guide support, a slag blocking mechanism, a projection pushing mechanism and the like which are arranged on a fixed clamping device. The manual centering function of the welding machine mainly completes centering work by adjusting the position of the mechanism and utilizing the rigidity of a guide shaft of the welding machine, and the centering effect is judged and further adjusted by adopting a visual inspection or touch mode; the automatic centering function mainly fixes the mechanism related to centering at a certain position through calibration, and under the condition of the position, two steel rails to be welded are positioned on the same axis, so that centering is realized, but the method cannot solve errors caused by appearance difference of the steel rails and abrasion of a centering device. Similarly, the welding machine does not have any measuring device, and cannot realize automatic centering, automatic measurement and automatic recording functions.
One known resistance flash welding installation suitable for rails is the swiss schlat company invention (european patent EP0499019B 1). This patent fixed rail flash welding machine's centering device adopts the four-arm structure, and the centering of accessible centre gripping in the two side work limit positions of railhead is realized to four groups arms of railhead and is adjusted, and the accessible is adjusted the position of installing proximity switch on centering adjusting device simultaneously and is realized the automatic centering function. However, because the welder disclosed in the patent adopts a direct current welding power supply, ferromagnetic substances in the mechanical arm between the two groups of electrodes are easily magnetized and adhere to welding slag, so that centering precision is influenced; without an on-line measuring device, closed-loop centering control cannot be formed, and high-precision automatic centering cannot be realized.
