Novel long rail changing operation method
The invention discloses a novel long rail changing operation method, which comprises the following steps of 1) connecting short rails to be replaced, and loosening buckle fittings; 2) enabling the rail changing vehicle to reach a rail changing construction site, aligning the new steel rail joint with a middle guide frame of the rail changing vehicle, and descending the rail changing vehicle to thelowest position by utilizing a lifting screw rod; 3) hoisting new steel rails on the two sides to enable the steel rails to enter the middle guide frame, and enabling the rail changing vehicle to move forwards continuously; 4) hoisting the old steel rails on the two sides to enable the old steel rails to enter the lower guide frame; 5) enabling the new steel rail to enter an upper guide wheel, enabling the rail changing vehicle to move forwards, and enabling the new steel rail to enter a guide groove and perform rail alignment; 6) cutting and polishing a new steel rail, enabling one end of the new steel rail to be butted with the paved steel rail, and adjusting a rail gap; and (7) enabling the rail changing vehicle to move forwards slowly to enable the steel rail to be separated from themiddle guide frame slowly, hoisting a new steel rail through a chain block before the steel rail is about to be separated from the rear guide frame of the rail changing vehicle, after the steel rail is completely separated from the rear guide frame, putting down the new steel rail and and merging into a rail sinking groove in a sleeper, and withdrawing the rail changing vehicle after rail changingis completed.
本发明公开了一种新型长轨换轨作业方法，包括1）将需替换的短轨连接好，松开扣配件；2）将换轨车到达换轨施工地点，使新钢轨接头对准换轨车的中部导框位置，利用升降丝杆，将换轨车下行至最低位置；3）吊起两侧新钢轨使钢轨进入中部导框中，换轨车继续前行；4）吊起两侧旧钢轨使旧钢轨进入下导框中；5）使新钢轨进入上导轮中，换轨车前行，使新钢轨进入导槽并对轨；6）切割并打磨新钢轨，使新钢轨一端与已经铺好的钢轨对接，并调整轨缝；7）换轨车缓慢前行，使钢轨缓慢脱出中部导框；待钢轨即将脱出换轨车的后导框前，采用手拉葫芦吊住新钢轨；待钢轨完全脱出后导框后，放下新钢轨并入轨枕上沉轨槽；完成换轨后，换轨车撤离。
