Abstract
Description
Technical Field
[0001] The invention relates to the field of replacement of rolling rollers, rolling roller seats or racks, and in particular to a roller changing and lateral shifting device with segmented linear guide rails on the transmission side of a leveling machine and a method for using the device. Background Art
[0002] For a six-roller skin-pass mill driven by upper and lower support rollers, in order to realize the hoisting and replacement of the rolls, the roll-changing vehicle transverse shifting device must be used to move the working rolls and intermediate rolls out of the transmission shaft area for hoisting operations.
[0003] At present, the roller-changing and transverse shifting device on the driving side of the six-roller leveling mill usually adopts the form of rollers or sliders, and the track adopts the design of two sections of disconnected tracks at the entrance and exit to avoid interference caused by the swing of the drive shaft and the lifting of the drive shaft. The disadvantage of the roller form is that the height of the roller-changing frame is too high. Once the roller diameter is large, the height of the rolling line needs to be increased accordingly; the disadvantage of the slider form is that the sliding friction coefficient is large, resulting in a large thrust required for transverse shifting, and the driving hydraulic cylinder must also be selected. At the same time, there is a risk of derailment when the slider moves across the track, and the failure rate of roller change is high. Summary of the invention
