DIRECTIONAL COUPLER STRUCTURE BY DIRECTIONAL COUPLER SWITCHING AND EXCHANGE OF RAILROAD

摘要

The present invention is a part of the railway track turnout, negative points for wear or damage, particularly the branch is started time require repair by a method of this gaenghwan this improved product quality and relates to the structure of the turnout according to such a method, it will improve the safety and robustness compared with the conventional and to gaenghwan assembly and maintenance is to be convenient. ; linear primary rail (1) and curved base rail (1 ') and the straight lead rail (3) and the cutting step for cutting each of the rails in proper position; The cut-point linear primary rail portion (1) and curved base rail (1 '), a straight lead rail (3), and two tongue rails (2) (2') to separate and remove the curve lead rail (3 ' ) is dismantled to remove the whole process and the rail; Part demolition and dismantling process and to remove the parts installed in 19 of the top 12 from the sleeper number; 12 No. 15 of the sleeper from sleeper (9) making the new point on the top plate (5), fixing the upper panel (5 '), mounting parts for installing the base plate (5 ") and the process for branch; curve lead rail (3 '), a linear primary rail (1) and curved base rail (1'), a straight lead rail (3) and curved tongue rail (2 ') and the straight tongue rail (2) the installation but, straight tongue rail (2) and curved tongue rail (2 ') is machined obliquely to the head (2a) of a " " shape, linear primary rail (1) and curved base rail (1 contacting this "head of a) (1a) is" " New installation and the processed form, straight tongue rail (2) and curved tongue rail (2 ') is fastened to install a rail to form a resilient elastic expression tongue rail cutting portion (2c) to the bottom (2b) of the rail Process and; sleeper number 18 and the straight base rail (1) and the curve 19 between the primary rail (1 ') and to the connection part, a straight tongue rail (2) and the curved tongue rail (2') are each straight lead rail (3 ) and curve lead rail (3 ') which is connected to the joint portion on each plate (8) the rail fastening process of signing the joint board; would that features constituted by
