METHOD FOR CLAMPING RAILS TO WELD RAILS WITH PRESSURE AND CLAMPING DEVICE USED THEREFOR

摘要

PURPOSE:To easily and rapidly carry out the correcting work of the positions in the vertical and right and left directions of rails mutually by making the clamping of the edge of each rail to two stages of the positioning clamping in the vertical direction and the positioning clamping in the right and left directions operatable independently separately from it. CONSTITUTION:Both clamping heads 1a and 1b are spread over the edges of both the rails 5a and 5b arranged with the edges abutted on each other from the above with an abutment 5c of the end faces between. Next, each upper surface of both the rails 5a and 5b is pressed against a corresponding leveler 21 by cylinder devices 23a and 23b of vertical positioning mechanisms 20 and the linearity of both the rails 5a and 5b in the vertival directions is maintained. Next, the linearity of both the rails in the right and left directions is maintained by two couples each of hydraulic cylinder devices 31a and 31b of both sides of rails of both the clamping heads 1a and 1b and clamped by the hydraulic cylinder device 31b from the opposide side. Then, in the case the right and left positions on both the rails 5a and 5b are dislocated, the fine adjustment can be easily carried out in a short time from both sides as the rail side.
