Description

Technical Field

[0001] The utility model relates to the technical field of roll changing devices, in particular to a roll changing device for metallurgical support rolls. Background Art

[0002] The use of support rollers can improve the utilization rate of industrial facilities and improve the finished product efficiency of industrial facilities. However, long-term use will cause the mechanical strength of the support rollers to decrease. At this time, they need to be replaced with a support roller changing device.

[0003] According to a support roller changing device disclosed in the patent website (authorization announcement number: CN 219380627 U), "the utility model relates to the technical field of roller changing devices and proposes a support roller changing device, including a movable seat, the four corners of the bottom end of the movable seat are fixedly connected to universal wheels, the four corners of the outer wall of the movable seat are provided with arcs of a certain angle, the top of the movable seat is axially connected to the middle part, and fixed bars are fixedly connected on both sides. In the utility model, a hydraulic column, a telescopic rod and a buffer spring are provided. When in use, the hydraulic column and the telescopic rod are started, so that the hydraulic column drives the workbench to move upward, and stops moving after moving to the appropriate position. At this time, the support roller to be replaced is placed in the arc groove at the top of the workbench. The support roller has a certain weight. When placed on the workbench, it will be pressed downward due to gravity. At this time, the buffer spring surrounding the outside of the telescopic rod will offset the gravity generated to a certain extent through its characteristics, thereby avoiding the support roller directly pressing downward, causing damage to the hydraulic column."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of the utility model, the movable seat is moved to a suitable position by the universal wheel, and then the servo motor is started. At this time, the threaded rod will be driven. Since the second movable component provided in the middle of the threaded rod is threadedly connected to it, when the threaded rod rotates, the second movable component will also move. In actual use, since the position of the universal wheel of the device is fixed, the center of gravity is easily offset during the lifting process of the support roller, resulting in unexpected situations. Therefore, it is necessary to improve a metallurgical support roller changing device to solve the above problems. Utility Model Content
