For solving the problems of the technologies described above, the utility model provides a kind of combined type down-the-hole hammer adjunction formula drilling rod mechanism that is connected, and replaces the conventional bolt type of attachment, in high-intensity oscillation, can realize the reliable connection of adjunction formula drilling rod.
The utility model is achieved through following technical scheme.
The described combined type down-the-hole of the utility model hammer adjunction formula drilling rod mechanism that is connected; Mainly form by right chuck, left chuck, last drilling rod, following drilling rod, wedge shape semi-ring, locking pin, hinge pin and drilling rod bearing pin; Right chuck is connected through the pin that is hinged with left chuck, forms the hinge revolute pair, and the outer convex edge of right chuck offers several locking pin-and-hole groups; Corresponding with right chuck; Chuck outer convex edge in a left side offers several locking pin-and-hole groups, and the left side locking pin-and-hole group of the right side locking pin-and-hole group of right chuck and left chuck forms the dislocation pin-and-hole, has a pair of near conllinear in the axis of the axis of right locking pin-and-hole group and left side locking pin-and-hole group; Locking pin is installed in this in the locking pin-and-hole, makes left chuck, right chuck form a clamping rings; Last drilling rod is connected through the drilling rod bearing pin with following drilling rod, and upper and lower drilling rod flange groove is laid the wedge shape semi-ring, left chuck, right chuck outsourcing wedge shape semi-ring, and the convex edge end of drilling rod bearing pin is positioned at the counterbore on the chuck; The inside groove of said left chuck, right chuck is set to the pressure conical surface; The work plane of said wedge shape semi-ring is an inclined working, and the angle of inclination is α, and the end face of two wedge shape semi-rings is fitted, and forms the conical ring of a fixed diameter, and the pressure conical surface that chuck is inboard and the work conical surface of wedge shape semi-ring are fitted.
The pressure conical surface of said left chuck, right chuck inside groove and the inclined working of wedge shape semi-ring mutually extruding and the plane effect through the wedge shape semi-ring on the drilling rod flange.
Compared with prior art; The technique effect that the utility model reaches is: 1. the utility model adopts dislocation hole calibration principle to realize being connected of drilling rod with low-angle conical surface pressing method; Replaced the conventional threads ways of connecting; In high-intensity oscillation, can realize the reliable connection of adjunction formula drilling rod, difficultly become flexible, come off; 2. the combination of different locking pin-and-hole and locking pin-and-hole in the utility model can change the distance between the work conical surface and the pressure conical surface, realizes the change of plane to drilling rod extruding dynamics; 3. the counterbore on the left and right chuck of the utility model is used for the convex edge end of double team drilling rod bearing pin, prevents that the drilling rod bearing pin from coming off in vibrations.
