Problems solved by technology
With the application of this method, the width control problem arises. It is difficult for one vertical roll mill to meet the widening problem caused by the large reduction. Therefore, the designer adopts the front and back vertical vertical roll mill type horizontal roughing mill to overcome the difficulty.
[0003] After applying this kind of rolling mill, it is difficult to replace the main transmission connecting shaft, because the traditional rough rolling mill only has the front vertical roll, and the connecting shaft can be replaced quickly by leaving a space behind the machine, but after installing the vertical roll mill at the front and rear, the connecting shaft There is no room for lifting and rotating, and there is no possibility of replacement

Embodiment Construction
[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0011] See figure 1 ,, a horizontal rolling mill connecting shaft replacement device for a vertical roll mill with front and back hanging. The roller track 5 is provided with a rolling wheel set 9 on the transmission side frame 8 . An upper beam 3 is arranged above the transmission side frame and the working side frame.
[0012] Its working process is: when dismounting, the connecting shaft 10 is hoisted with the big hook head 1 and the small hook head 2, exceeding the height of the trolley 7, and then one end of the connecting shaft 10 is placed on the trolley 4 on the trolley 7, and the start The crane drives the connecting shaft 10 to move to the working side frame 6, the connecting shaft 10 rolls on the rolling wheel set 9, and the rolling wheel set 9 drives the connecting shaft 10 to drag the trolley 4 to move on the trolley 7 until the c...

The horizontal drive shaft quick changing device for back and forth hanging edger roller comprises big hooks and small hooks, made of relatively moving small carts on the bench car, with rolling wheel set on the drive side machine bracket. Using this quick drive shaft change, it makes the change of its main drive connection shaft, with greatly reduced changing time. It is simple in operation, reasonable in structure ad high in working efficiency.
Description
technical field [0001] The invention relates to a replacement device and method for mechanical equipment, in particular to a replacement device and method for a horizontal rolling mill connecting shaft of a front and rear vertical roll mill. Background technique [0002] With the development of steel rolling technology, short-process rolling technology has been widely used. This technology consumes less energy and has a fast rolling rhythm, which can greatly reduce costs and realize profits. In the short process technology, the designer adopted the technology of a roughing mill to increase the rigidity of the frame section of the rolling mill and increase the transmission rolling force to realize the large reduction rolling of the hot billet, thereby shortening the entire process line . With the application of this method, the width control problem arises. It is difficult for one vertical roll mill to meet the widening problem caused by the large reduction. Therefore, the d...
