Said roll change buggy includes the following several portions: upper platform, lower platform, two supporting frames, two shearing-fork type supporting mechanism formed from two upper supporting arms, two lower supporting arms, one hydraulic cylinder connecting shaft, transverse shaft and pins, a hydraulic motor and a roll-pulling buggy. Said invention also provides its working principle and its concrete operation method.
Description
Technical field
The present invention relates to a kind of milling train corollary equipment.Be used for changing the all-hydraulic automatic adjusting lifting roll change buggy of roll when specifically, being the milling train maintenance.
Background technology
Know all that at the milling train production industry after roll used a period of time, its surface smoothness can reduce, thereby influences the surface smoothness of band, make the strip quality that rolls out descend.Therefore, roll need regularly replace.Traditional roll-changing method cooperatively interacts with artificial, driving and roll to be changed is carried out push-and-pull realizes.This roll-changing method, not only time-consuming, effort, changing a roll often needs several hrs, and very dangerous.
Summary of the invention
The problem to be solved in the present invention provides a kind of roller changing small car for rolling mill.Adopt this roller changing small car for rolling mill to change roll, save time, laborsaving, safe and reliable.
For addressing the above problem, take following technical scheme:
