Problems solved by technology
Because the overall movement of the roller and the bearing seat is relatively long, the roller changing track is usually directly spliced by two rails, and the joint is not dense and has no transition, and it is easy to appear unevenness or even steps at the joint of the two sections of the track On the other hand, when the chock and roll move to this joint as a whole, there will be bumps and collisions with the rails, and the overall mass of the chock and roll is heavy and the volume is large. In this case, there will be a danger of overturning, which will endanger the life safety of the operators

The invention provides a modified rolling mill roll-changing rail with simple structure and safe use. The roll-changing rail comprises two sections of tracks which are spliced together. The roll-changing rail is characterized in that the splicing ends of the two tracks are both L-shaped joints, the upper surfaces of the L-shaped joints are curved surfaces, and the L-shaped joints of the two tracks are inserted and spliced together.
Description
(1) Technical field [0001] The invention relates to the field of roll machine auxiliary equipment, in particular to an improved roll changing track of a roll machine. (2) Background technology [0002] The two ends of the roll of the roll machine are installed in the bearing housing. When installing or replacing the adjusting roll, the roll and the bearing housings at both ends need to be removed from the roll mill frame along the rail as a whole before installation or replacement. Because the overall movement of the roller and the bearing seat is relatively long, the roller changing track is usually directly spliced by two rails, and the joint is not dense and has no transition, and it is easy to appear unevenness or even steps at the joint of the two sections of the track On the other hand, when the chock and roll move to this joint as a whole, there will be bumps and collisions with the rails, and the overall mass of the chock and roll is heavy and large, which will cau...
