Zusammenfassung: | The utility model discloses a mine buffering and damping device for coal mining, and relates to the field of coal mining. The device comprises a bottom plate, a transverse plate and a top seat, a vertical column is arranged on the outer side of a piston column in a sleeved mode, a limiting groove is formed in the bottom of the vertical column, a buffer spring is arranged on the top of the limiting groove, a damping spring is arranged on the outer side of the vertical column in a sleeved mode, and a guide mechanism is arranged on the outer ring of the top seat. External force is preliminarily absorbed and decomposed, an inserting rod is inserted into an inserting groove, the stand column is locked and limited, next operation of the external force is prevented in time, the stability of the stand column is improved, the influence of instant acting force on the device is reduced, and the overall damping and buffering effect is greatly improved; and a guide mechanism is arranged, so that the movement track of tran |
