Description

Technical Field

[0001] The invention relates to the technical field of rail profile measurement, and in particular to a rail profile profiling template measuring tool. Background Art

[0002] Rail grinding is an effective means of preventing and repairing rail defects. Grinding can repair or reduce rail surface damage, prevent contact fatigue, corrugation and other defects, effectively improve wheel-rail matching, improve train running quality, and extend rail service life. Rail grinding operations usually require timely and effective inspection and evaluation of the grinding profile and grinding quality.

[0003] At present, the measurement of rail profile in China can be evaluated by rail profile meter or template ruler. The rail profile meter scans the rail profile and uses the sensor device to obtain the relative position of each point on the rail, and then obtains the data information of the rail profile. This method needs to further process the data after the on-site inspection. Although the evaluation is more accurate, it is more troublesome to use. The template ruler can directly evaluate the rails at the grinding site, which is fast and convenient.

[0004] The current template rulers are all fixed templates, which have at least the following disadvantages during use:

[0005] (1) According to the rail grinding standard requirements, when measuring the cross-section grinding surface of the rail on site after the grinding machine is operated, it is usually necessary to evaluate the appearance of the cross-section grinding surface, and at the same time, it is necessary to compare the cross-section dimensions of the rail on site with the template. The current template ruler can only observe the profile deviation and cannot directly obtain the cross-section of the rail. Not only can the measurement of the cross-section grinding surface width not be accurately located and measured, but also the cross-section dimension information of the rail cannot be directly and quickly obtained on site, which affects the evaluation effect and efficiency of the grinding quality.

[0006] (2) If the template ruler is placed directly on the on-site rail, the deviation between the on-site rail and the template can be visually inspected, and the cross-section cannot be intuitively evaluated. When the existing template ruler is used to evaluate the profile difference on-site, the size of the difference from the standard profile can only be subjectively evaluated by the naked eye.

[0007] (3) In order to meet the needs of train operation on different lines, railway lines of different grades often need to be designed according to specific line conditions, so as to obtain the management profile of the specific line. The current template scale has a single and fixed size. Once the grinding management profile of the rail changes, the template scale will not be applicable and the template scale needs to be redesigned. The scope of application is narrow and it is impossible to achieve personalized management of the grinding management profile of different lines. Summary of the invention

[0051] Optionally, the locking device 4 includes a locking stud, and a threaded hole is provided on the front end plate 113. The locking stud is inserted into the threaded hole and can be abutted against the adjacent contour plug plate. Rotating the stud can press the contour plug plate, thereby locking the relative position of the contour plug plate and the support device 1.

When the first clamping plate 51 and the second clamping plate 52 are at the farthest distance, the end of the sleeve 53 will not separate from the accommodating groove 522. The setting of the sleeve 53 can isolate the forward and reverse rotating screw 41 and the profiling insert, so as to prevent the rotation of the forward and reverse rotating screw from affecting the stability of the profiling insert in the process of forming the profile, thereby making the profiling more accurate.

[0054] like Figure 7 As shown, a long groove is provided on the inner wall of the accommodating groove 522, and sliders 531 are provided on the cylinder walls at both ends of the sleeve 53.
