The invention discloses a simple clamping and replacing device for a rolling mill roll collar and a replacing method. The middle parts of a clamping handle I and a clamping handle II of the device are hinged, the inner sides of the lower ends of the clamping handle I and the clamping handle II are respectively provided with a clamping foot matched with a roll collar hole-shaped groove surface, the outer sides of the upper parts are respectively provided with a handle, the upper ends are connected with a movable pulley, and a fixed pulley I is connected with a travelling crane. The method comprises the following steps: rechecking the standby roll collar; checking whether the loading and unloading device is normal; after the rolling mill is stopped stably, the roll collar is dismounted through a loading and unloading device, and then the roll collar is taken down through the device; cleaning a rolling mill shaft head and a roll collar gasket; putting the qualified roll collar into the contact roll collar gasket by using the device; and pressing the roll collar by using a loading and unloading device to finish the replacement of the roll collar. The clamping feet are matched with the hole-shaped groove faces so that the roll collar can be prevented from falling off during hoisting, the hinged X-shaped structure can form clamping force to clamp the roll collar in the hoisting process, the problem that a traveling crane is large in adjustment amplitude and difficult to position can be solved by adding the fine-adjustable pulley block, and the roll collar hoisting device has the advantages of being simple in structure, easy and convenient to operate, firm in clamping and high in working efficiency.

    本发明公开一种轧机辊环的简易夹持更换装置及更换方法,所述装置的夹持柄Ⅰ与Ⅱ中部铰接,夹持柄Ⅰ及Ⅱ下端内侧分设与辊环孔型槽面配合的卡脚且上部外侧分设手柄、上端与动滑轮连接,定滑轮Ⅰ与行车连接。所述方法是复查备用辊环;检查装卸压装置是否正常;轧机停稳后用装卸压装置卸下辊环,后用前述装置将辊环取下;清洗轧机轴头及辊环垫片;用前述装置将合格辊环放入至接触辊环垫片;用装卸压装置将辊环压紧,完成辊环更换。本发明的卡脚与孔型槽面配合可避免吊装时辊环脱落,铰接的“X”形结构可在吊装中形成夹持力夹紧辊环,增加可微调的滑轮组可避免行车调整幅度大而难定位的问题,具有结构简单、操作简便、夹持牢靠、作业效率高的特点。
