Grouting pipe propelling device

The embodiment of the utility model discloses a grouting pipe propelling device, and belongs to the technical field of mine grouting, the grouting pipe propelling device comprises a propeller and a propelling gun, and the propeller comprises an outer ring propelling assembly, a center positioning assembly and a tail end propelling assembly. According to the embodiment of the utility model, hexagonal steel in the center positioning assembly is more beneficial to positioning of a grouting position; a propelling stopper is arranged in the tail end propelling assembly, can forwards stop the outer ring propelling assembly and can also backwards stop the rear recommended gun; during grouting, the cylindrical grouting pipe only needs to be inserted into the straight through hole of the propelling gun and then penetrates through the cylindrical hollow hexagonal steel, and grouting can be conducted, so that convenience and practicability are achieved; moreover, the cylindrical hollow six-edge steel is generally common
