The roll changing structure comprises a lifting hook, a steel wire rope and a height adjuster are connected to the lifting hook in a hung mode, a lifting beam is connected to the lower end of the steel wire rope and the lower end of the height adjuster, the height adjuster controls the height of the lifting beam, a shaft head clamp is installed at the right end of the lifting beam, and the shaft head clamp is used for clamping the wringing roll. A balancing weight is installed on the left side of the lower surface of the hanging beam and keeps balance of the hanging beam, the crown block bears the weight of the wringing roller, the crown block can adjust the positions of the hanging beam and the shaft head clamp, the chain block is used for finely adjusting the height of the shaft head clamp, and it is ensured that the shaft head clamp stably clamps the wringing roller. The wringing roller can be smoothly clamped and slowly moved towards the pulling-out direction of the wringing roller by utilizing the crown block, so that the wringing roller mounted at the extreme position is dismounted and hoisted, and a series of problems that the wringing roller is near the edge in the high altitude, a roller replacing trolley cannot be mounted and the dismounting and hoisting distance is not enough are solved.

    本发明公开了一种挤干辊的换辊结构及换辊方法,包括吊钩,所述吊钩上挂接有钢丝绳和高度调节器,所述钢丝绳和高度调节器下端连接有吊梁,高度调节器控制吊梁的高度,所述吊梁右端安装有轴头夹具,所述轴头夹具用于夹住挤干辊,所述吊梁下表面左侧安装有配重块,所述配重块保持吊梁的平衡,通过天车承载挤干辊的重量,天车可以调整吊梁和轴头夹具的位置,使用手拉葫芦对轴头夹具高度进行微调,确保轴头夹具稳定夹住挤干辊,在极限位置时,可以顺利夹住挤干辊,利用天车慢慢向挤干辊拉出方向移动,从而拆除及吊装安装于极限位置的挤干辊,解决了挤干辊在高空临边、无法安装换辊小车以及拆卸吊装距离不够的一系列问题。
