Description

Technical Field

[0001] The utility model relates to the field of sectional ground roller station design, in particular to a heavy sectional ground roller station. Background Art

[0002] The ground roller station is one of the commonly used equipment in the steel coil preparation stage of the cold rolling production line. It uses a transmission motor to drive the roller to rotate, and drives the steel coil placed on the roller to rotate, so as to realize the steel coil preparation work such as removing the strapping or finding the strip head.

[0003] According to the layout direction of the ground rollers, the existing ground roller stations can be divided into two categories: the ground rollers of the first type of ground roller station are parallel to the center line of the coil transport equipment, such as Figure 1 As shown in the figure, since the coil transport device 5 does not interfere with the ground roller in the running direction, the free roller 2 and the driving roller 3 of the ground roller can be made into a full-length integral roller body, and the driving roller 3 is driven to rotate by the driving motor 4. This type of integral ground roller station has a simple structure and is easy to expand and apply. At present, there are integral light, medium or heavy ground roller stations for various tonnage steel coils; the ground roller of the second type of ground roller station is perpendicular to the center line of the coil transport device 5, such as Figure 2 As shown, since the coil transport device 5 is perpendicular to the center line of the ground roller in the running direction, the roller of the ground roller must be made into a segmented roller body. The structural type of this type of segmented ground roller station is relatively complex. At present, the common layout type of the segmented ground roller station is that the free roller 2 and the driving roller 3 of the ground roller are separated from the middle and designed into two sections of free rollers 12 and two sections of driving rollers 13, wherein the ends of the two sections of driving rollers 13 are symmetrically installed with two passive sprockets 10, and are connected to two active sprockets 9 installed at both ends of the same transmission shaft 7 through two chains 8; the transmission shaft 7 is supported by two bearing seats 11 installed on the roller support 14, and is connected to the transmission motor 4 through the coupling 6; the transmission motor 4 and the coupling 6 drive the transmission shaft 7 to rotate, and drive the active sprockets 9, chains 8 and passive sprockets 10 on both sides to operate simultaneously, thereby driving the two sections of driving rollers 13 to rotate simultaneously; four sections of rollers are installed on the roller support 14, and the middle of the roller support 14 is left empty for the coil transport device 5 to pass through.

[0004] Since the weight of steel coils carried by the existing segmented roller stations is mostly below 30t, they are medium or light roller stations, and the space left in the middle of the roller supports is limited, making them unable to adapt to the connection with large-scale coil transport equipment for coil receiving and transportation; at the same time, due to the limitation of the height of the roller supports, the layout of its transmission device is close to the ground, which will occupy a certain ground space and is not conducive to operation and maintenance.

[0005] Therefore, it is necessary to design a heavy-duty segmented roller station to overcome the above problems. Utility Model Content
