when the compression roller (4) presses the strip (21), the driving device (5) drives the base (22) of the belt track to press downwards, the driving device (5) continues to press downwards after the compression roller (4) is in contact with the surface of the strip (21), the lower surface of the base (2) with the track is tightly attached to the upper surface of the flat plate (13) of the roller frame (3) at the moment, positioning in the height direction is achieved, the levelness tolerance of the compression roller (4) is guaranteed, the vertical roller (6) is separated from the roller changing track (10), all side rollers (7) are tightly attached to the guide surfaces (12) on the two sides of the long groove (9), positioning of the compression roller (4) in the rolling direction of the rolling mill is achieved, and the parallelism tolerance of the compression roller (4) and other rollers is guaranteed.
10. The use method of a floating type press roll device capable of efficiently changing rolls as claimed in claim 9, wherein: when the roller (4) needs to be replaced, the driving device (5) lifts the base (2) with the track, the vertical roller (6) falls on the surface of the roller replacing track (10), the upper surface of the flat plate (13) of the roller frame (3) is separated from the positioning surface (11) of the base (2) with the track, the limiting block (1) is taken out, and then the whole roller frame (3) and the roller (4) are pulled out of the base (2) with the track and are lifted away by a workshop crane;
when the replaced compression roller (4) is reset, a workshop travelling crane is used for integrally hoisting the roller frame (3) and the compression roller (4) to the side of the base (2) with the track, the vertical plate (14) of the roller frame (3) is aligned to the long groove (9) in the base, the compression roller (4) is pushed to reset, the limiting block (1) is inserted into the limiting groove (20), and the roller replacement is completed.
