Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, fig. 2 and fig. 3, a front view, a top view and a left view of the reeling rail provided with the buffering device in the present invention are provided, the reeling rail is composed of two rail beams 1 arranged in parallel and a plurality of driving rollers 2 arranged on the rail beams, two ends of the driving rollers 2 are arranged on the rail beams 1 through bearings, and a driving motor 15 for driving the driving rollers 2 to rotate is fixed on the rail beams 1. Carry out the transmission through driving chain 19 between the adjacent driving roller 2, the both ends of driving roller 2 are shaft shoulder 18, and the saddle both ends of transportation coil of strip are placed on shaft shoulder 18 to in-process at driving roller 2 pivoted, drive the saddle and realize the coil of strip transportation. An upright post 16 is also fixed to the illustrated reeling rail, and a guard plate 17 is fixed to the upper end of the upright post 16. And a buffer device 3 is arranged between the two ends of the two track cross beams 1 and the foundation.
As shown in fig. 4, a schematic structural diagram of the buffering device of the present invention is shown, which is composed of a connecting end cover 4, a supporting end cover 5, an upper pressing end cover 6, a lower pressing end cover 7, a disc spring 8, a supporting sleeve 9, a base 10, a connecting bolt 11, a connecting bolt 12, an adjusting bolt 13 and a connecting bolt 14, wherein the base 10 is fixed on a foundation through the connecting bolt 14. The upper end of the connecting end cap 4 is shown fixed to the rail cross member 1 via a connecting bolt 11, and the lower end of the connecting end cap 4 is located in the support sleeve 9. The supporting end cover 5 is positioned at the periphery of the connecting end cover 4, and the supporting end cover 5 is connected with the supporting sleeve 9 through a connecting bolt 12 (in a counter bore mode).
