The invention relates to the field of steel coil preparation, and discloses a main screw-down oil cylinder replacement mechanism of a rolling mill. The main screw-down oil cylinder replacing mechanism is a special replacing device for the main screw-down oil cylinder in a rolling mill, the main screw-down oil cylinder replacing mechanism replaces an upper bearing seat and a claw type jack to bear the main screw-down oil cylinder through cooperation with the heightening frame, various limitations and inconvenience caused when the upper bearing seat and the claw type jack support the main screw-down oil cylinder are overcome, and the main screw-down oil cylinder replacing mechanism is suitable for being used in a rolling mill. The working efficiency of maintenance and replacement is greatly improved; the supporting roller replacing device drives the main screw-down oil cylinder to enter the rolling mill, so that the receiving disc of the main screw-down oil cylinder replacing mechanism is located under the main screw-down oil cylinder, then the lifting oil cylinder drives the supporting plate and the receiving disc to ascend, the receiving disc supports the bottom of the main screw-down oil cylinder, and then a fixing bolt of the main screw-down oil cylinder is loosened; and then the lifting oil cylinder drives the main screw-down oil cylinder on the receiving disc to quickly descend to a lower height, and finally, the supporting roller replacing device safely and quickly moves the main screw-down oil cylinder out of the rolling mill.

    本发明涉及钢卷制备领域,并公开了一种轧机的主压下油缸更换机构;本发明提供主压下油缸更换机构是轧机中的主压下油缸的专用更换设备,通过与垫高架的共同配合,代替了上轴承座和爪式千斤顶对主压下油缸进行承接,解决了因上轴承座和爪式千斤顶对主压下油缸进行支撑的各种局限和不便,大大提高了维护更换的工作效率;支撑辊换辊装置驱动主压下油缸进入轧机内部,使主压下油缸更换机构的接盘位于主压下油缸的正下方,然后举升油缸驱动托板和接盘上升,使得接盘托住主压下油缸的底部,继而松开主压下油缸的固定螺栓,举升油缸再驱动接盘上的主压下油缸快速下降到一个较低的高度,最后支撑辊换辊装置安全且快捷地将主压下油缸搬出轧机。
