The utility model provides a drag chain collaborative guiding device of a large-dip-angle thin seam climbing floor coal mining machine, which comprises a base and a pushing jack, the base comprises a first base and a second base, and two ends of the pushing jack are respectively connected with the first base and the second base. The telescopic movement of the pushing jack can drive the first base and the second base to do translational movement in the same direction or away from each other; the stand column is arranged on the base, the column cap is arranged on the stand column, and the column cap can be pressed tightly or away from the mining roadway wall through stretching and retracting of the hydraulic assembly so as to fix or loosen the base. A traditional anchoring type fixing mode is changed, dependence of a steel wire rope guiding and fixing device on the rock mass is eliminated, and fixing is more reliable. The base can be pushed to advance by pushing the jack, so that the traction chain is driven to
