The invention discloses a fastening device for assembling a water stop ring of a supporting roller. The fastening device comprises arc pieces with same shapes and certain thicknesses spliced into a round tube shape. A channel that is as long as the inner circumference of the arc pieces is formed in the upper portion of the inner circumference of the arc pieces. A semicircular lining ring is contained in the channel. A plurality of through holes are formed in the two ends in the circumferential direction of the arc pieces. After every two adjacent arc pieces are spliced, bolts penetrate throughthe plurality of through holes and then nuts are screwed at the ends of the bolts such that the arc pieces are fixed. Hanging lugs are disposed on the outer circumference of the arc pieces. The fastening device can meet the requirements of roller necks of various rollers by changing the diameter of the lining ring, namely by preparing lining rings of different diameters, thereby reducing cost by90% or more; and once the inner circumference of the lining ring is damaged during specific production, the lining ring can be replaced in time, so that safety is higher and work efficiency is higher.
本发明公开了一种用于支承辊挡水圈装配的紧固装置,包括形状相同、拼接形成圆管状的具有一定厚度的弧片,所述弧片的内圆周上部具有一条与弧片内圆周等长的槽道,槽道内容纳半圆形的内衬环;所述弧片的圆周方向的两端设有若干通孔,当两块弧片拼接后,通孔内贯穿螺栓后通过螺母在螺栓端部旋接进行固定;所述弧片的外圆周上设有吊耳。本发明通过改变内衬环的直径来适应各种轧辊辊颈的要求,只需要准备不同直径的内衬环即可,成本下降90%以上;在具体生产时一旦出现内衬环内周破损的情况,可以及时更换,安全性能更好,工作效率更高。
