Detailed Description
The present invention will be further explained with reference to the accompanying drawings, but the scope of the present invention is not limited to the accompanying drawings.
Fig. 1 is the utility model discloses dismouting device schematic structure diagram, fig. 2 is the utility model discloses the installation schematic diagram of connecting line connector and coal gun pipe fitting, fig. 3 is the utility model discloses coal gun pipe fitting structure schematic diagram, fig. 4 is the utility model discloses quick-operation joint structure schematic diagram, as shown in the figure:
the utility model discloses a blast furnace coal gun pipe fitting quick assembly disassembly device comprises a pneumatic air pick 1 and a quick connector 8, wherein two hemispheroid clamping convex points 10 are additionally arranged on the outer side wall of one side of a coal gun pipe fitting 9 along the diameter direction; one side of a handle 6 of the pneumatic air pick 1 is communicated with compressed air through an air pipe connector 7; the tail end of the impact head at the other side of the pneumatic air pick 1 is screwed up and fixed with a connector 5 through threads; the quick connector 8 is a cylinder, one end of the quick connector is inwards provided with a cylindrical groove with the same outer diameter as the coal gun pipe fitting 9, and the other end of the quick connector is fixed with the connector 5; a clamping rotary groove 11 is axially formed in the diameter direction of the groove, and the clamping rotary groove 11 comprises an axial slot part 12 and a clamping part 13 in the circumferential direction; the opening width of the slot portion 12 and the engaging portion 13 is equal to the diameter of the ball where the engaging protrusion 10 is located, and the opening direction of the engaging portion 13 is the same.
